Dragan Spiridonov 462605b081 feat(llm): external provider registration (ADR-127, #628)
Let a downstream tool give a host it supervises its own AQE provider
identity, instead of forking the provider enum or projecting the host
onto an unrelated vendor.

Two surfaces:
  - `externalProviders` in .agentic-qe/llm-config.json — declared as data,
    so one config file is picked up by both the CLI and MCP bundles.
  - registerProvider() from agentic-qe/shared/llm for in-process embedders.

Also:
  - Open LLMProviderType to registered identities while keeping the shipped
    set closed, so per-provider maps still fail the build when a built-in is
    added. ALL_PROVIDER_TYPES is unchanged.
  - Fix billing misattribution: any subscription-billed provider was reported
    as running on the user's Claude Code subscription.
  - Export ./shared/llm, an import path the module had documented but which
    was never actually exported.

chore(release): bump version to v3.13.12

Also brings .claude-plugin/plugin.json (stale since v3.13.3) and
.claude/skills/skills-manifest.json fleetVersion (stale since v3.13.10)
back in step with package.json.

Changelog

All notable changes to the Agentic QE project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[3.13.12] - 2026-08-21

Downstream tools can now give a host they supervise its own AQE provider identity, instead of forking the provider enum or misreporting the vendor that served the work.

Added

  • Added external provider registration, so a project can declare a host it runs and select it with AQE_LLM_PROVIDER=<host>. Declare it as data in .agentic-qe/llm-config.json under externalProviders — the declaration is picked up identically by the CLI and the MCP server — or call registerProvider() when embedding AQE as a library. Declared hosts are first-class everywhere a provider is accepted: defaultProvider, fallbackChain, and agentOverrides (#628).
  • Added agentic-qe/shared/llm as a package export. The module's own usage example had documented this import path while it was never actually exported, so library consumers had to reach it through agentic-qe/shared (#628).

Fixed

  • Corrected billing attribution for subscription-billed providers. Any provider reporting subscription billing was described as running on the user's Claude Code subscription, which was accurate only while the two built-in subscription providers were the only ones possible. External hosts are now reported as external — <mode> (declared by <source>, not verified by AQE) in aqe health and in the startup notice (#628).

Changed

  • The provider type is now open to registered identities while the shipped set stays closed, so per-provider lookup tables still fail the build when a built-in provider is added without updating them. ALL_PROVIDER_TYPES continues to mean "the providers AQE ships" and is unchanged (#628).
  • aqe llm providers now lists declared external providers, marked with * and a footnote so they are never mistaken for providers AQE ships (#628).

[3.13.11] - 2026-08-14

Diagnostics, native ESM imports, and learned pattern visibility now behave consistently across CLI, MCP, hooks, and background learning workflows.

Added

  • Added read-only SONA pattern counts and statistics to MCP pattern responses and the dashboard without opening a second learning database connection (#624).
  • Added backward-compatible pattern details to JSON hook responses and opt-in learned guidance for reasoning-bank requests (#625).

Fixed

  • Routed quality-judge provider errors, timeouts, and unparseable-response diagnostics to stderr in the CLI and the MCP logger, preserving valid JSON on stdout (#621).
  • Normalized extensionless relative specifiers throughout the emitted public ESM dependency graph and added native imports for every package export, including the RuVector barrel and coordinator GNN. The package now declares its runtime TypeScript parser dependency explicitly (#624).
  • Filtered learned hook guidance through the existing relevance floor while preserving static guidance and no-match behavior (#625).
  • Stamped consolidated patterns with last_used_at, applied legacy-safe confidence decay, and preserved the newest timestamp across evolution merges (#626).

Changed

  • Consolidated pattern rows with recorded usage now consistently carry a non-null recency timestamp. No database migration is required.

[3.13.10] - 2026-08-06

Pattern consolidation and export now operate on complete, accurate learning data; repeated initialization preserves operator thresholds; and large PageRank workloads gain a resilient asynchronous execution path.

Added

  • Added worker-thread weighted PageRank with deterministic TypeScript fallback and an optional native RuVector solver contract for future availability.
  • Added explicit pattern promotion through the same persistence, audit, and event flow used by automatic learning.

Fixed

  • Fixed learning consolidation to enumerate the complete stored pattern view, perform reported promotions, preserve dry-run behavior, and disclose per-pattern write failures (#618).
  • Fixed monthly aggregate reinforcement to write the per-use audit trail and run the idempotent three-dimensional promotion gate (#618). The CLI now reports and enforces the minimum confidence criterion as well.
  • Fixed learning exports to preserve real success counts, rates, quality scores, and memory tiers (#618).
  • Fixed repeated initialization so configured learning quality and promotion thresholds are not overwritten (#619).
  • Fixed the upgrade advisory for the unpublished @ruvector/solver package; its absence is no longer presented as an installable or strict-mode failure (#617).
  • Corrected RuVector solver documentation to describe the weighted iterative implementation accurately.

Changed

  • Updated the development-only Ruflo goal UI lock to React Router 7 via #616. Ruflo remains outside AQE's published runtime dependency surface.

[3.13.9] - 2026-08-04

Development-time Ruflo dependency snapshots now resolve patched releases for nearly all remaining Dependabot findings without changing AQE's runtime dependency surface.

Security

  • Refreshed six npm and pnpm locks covering the Ruflo root, v3 monorepo, goal UI, graph-intelligence plugin, and ruvocal snapshot.
  • Added targeted transitive floors for adm-zip, sharp, OpenTelemetry, uuid, thrift, cookie, and picomatch, among other patched packages.
  • Removed an unused semantic-release dependency from the v3 snapshot, eliminating its vulnerable bundled npm toolchain.
  • Kept the goal UI on React Router 6.30.4: moving to 7.18 would replace two medium advisories with a newer high-severity RSC-mode CSRF advisory.

Changed

  • Added the current pnpm workspace override location for the Ruflo root while retaining compatibility metadata for older pnpm clients.
  • Ruflo remains development-time tooling and is not added to AQE runtime dependencies. No API, database, or configuration migration is required.

[3.13.8] - 2026-08-04

CI performance checks are now measured without coverage instrumentation, and the remaining stateful learning-engine suite uses bounded, isolated storage. Development-time Ruflo dependency locks also include the latest security remediations.

Fixed

  • Coverage no longer makes performance timing flaky (#608). Pure performance baselines run in the dedicated Performance Gates job, while coverage continues to exercise Hopfield correctness without enforcing a wall-clock threshold distorted by V8 instrumentation.
  • Learning-engine pattern tests no longer accumulate database state (#610). Every case uses a fresh ephemeral unified store, asserts a stable initial pattern count, closes the database, and removes only its temporary directory after execution.

Changed

  • The dedicated Performance Gates job now runs the Milestone 1 baselines and the Hopfield single-recall benchmark in addition to the aggregate gate.
  • Refreshed Ruflo development-tool dependency locks from #612, including patched versions of hono, undici, sharp, qs, postcss, and related transitive packages. Ruflo remains development-time tooling and is not added to AQE runtime dependencies.

[3.13.7] - 2026-08-04

Memory operations now disclose partial semantic-index failures, and ANN search returns stable, qualified top-K results. The release also includes the latest merged dependency security remediations.

Fixed

  • Memory stores disclose semantic-index failures (#603). KV persistence can still succeed when the optional embedding capability is unavailable, but structured MCP/JSON output now reports VECTOR_INDEX_UNAVAILABLE and the human CLI prints a warning instead of implying that vector indexing worked.
  • ANN top-K results remain stable across requested limits (#604). Native HNSW queries use request-independent traversal breadth within their qualified range, retain deduplication headroom, and iteratively qualify logical and physical namespace filters. Semantic results now report backend, index type, approximation status, estimated recall, and qualified K limits.
  • Critical dependency alerts remediated (#607). Root and shipped development-tool lockfiles now resolve patched fast-xml-parser, hono, minimatch, and serialize-javascript versions without changing public AQE APIs.

Changed

  • Refreshed Ruflo development-tool dependency locks from #605. Ruflo remains development-time tooling and is not added to AQE runtime dependencies.

[3.13.6] - 2026-08-03

Learning records and semantic search data now persist and resolve reliably, while operators have a safe way to repair older patterns that are missing embeddings.

Added

  • Pattern embedding repair (#584). aqe learning backfill-embeddings reports or repairs learned patterns that are missing semantic vectors, with dry-run, JSON, and configurable batch-size support.

Fixed

  • Namespaced semantic search returns the right memories (#601). Logical namespace filtering now happens while ANN candidates are gathered, so a relevant scoped result is not hidden by higher-ranked vectors from unrelated namespaces.
  • Hook embeddings persist before exit (#581). Short-lived hook processes now wait for captured-experience vectors to be stored instead of abandoning in-flight writes.
  • Embedding setup guidance names the correct environment variable (#582), so users configuring an external provider are directed to AQE_EMBEDDER_ENDPOINT.
  • Experience replay initializes once under concurrency (#583). Concurrent callers now share initialization work, while a failed attempt remains retryable.
  • Reasoning-bank unit tests remain isolated (#588). Each case now uses an ephemeral unified store, preventing transferred patterns from accumulating until setup hooks time out.
  • Embedding repair protects semantic consistency (#584). Backfill now fails clearly when no semantic provider is available instead of mixing hash proxies into the semantic index.

[3.13.5] - 2026-08-03

Quality decisions and generated tests now carry evidence that reflects what AQE actually measured or executed, while initialization and embedding workflows are more reliable across supported environments.

Added

  • Measured quality-gate evidence (#596). CLI and MCP quality evaluation now share canonical thresholds and require fresh, attributed measurements for coverage, passing tests, critical bugs, code smells, security findings, technical debt, and duplication. Missing, malformed, or stale evidence fails closed instead of silently receiving a fabricated passing value.
  • Optional status-line installation (#591). aqe init --no-statusline skips AQE's status line, removes an existing AQE-owned status line during an upgrade, and preserves a project-authored status line.

Fixed

  • Generated tests are trustworthy and executable (#577). Test generation preserves framework imports, validates evidence before reporting success, and no longer treats structurally incomplete output as a passing quality result.
  • Node's built-in test runner is honored end to end (#592). Test discovery filters Node test files correctly, execution uses the selected framework, and retry confidence remains bounded.
  • Batch embedding semantics are consistent (#585). Mixed batches send only semantic content to the embedding provider, nonsemantic entries receive zero vectors in their original positions, and all-nonsemantic batches avoid provider initialization entirely.
  • HNSW initialization works in native ESM (#586). Runtime dependency loading no longer assumes a CommonJS global require.
  • Learning-engine tests use isolated persistence (#588), preventing shared worker databases from accumulating duplicate genesis data and causing long test runs.

Changed

  • Refreshed bundled Claude helpers and development-only Ruflo dependencies, including upstream security and compatibility fixes.

[3.13.4] - 2026-08-02

Codex users now receive a complete, upgradeable Agentic QE workflow instead of an MCP entry and partial instructions that could drift from the installed hooks and skills.

Added

  • A curated Codex-native QE workflow fleet (#587). New research, dependency-aware planning, and lightweight Ruflo orchestration skills join the existing quality-planning, testing, and review workflows. Ruflo remains optional development-time guidance, enabled explicitly with --with-ruflo, and is not a runtime dependency.
  • End-to-end Codex installation verification. aqe platform verify codex now checks MCP configuration, AQE instructions, lifecycle hooks, adapters, runtimes, and every required skill, with a failing exit code when the install is incomplete.
  • A package-boundary release gate. npm run verify:codex-package verifies the actual npm tarball contains all curated skills and hooks, excludes the vendored Ruflo tree and dependencies, and confirms every MCP tool named in generated Codex guidance is registered.

Fixed

  • --no-mcp now applies to Codex installs. Previously the Claude phase honored the flag but the Codex asset phase still wrote .codex/config.toml.
  • Codex upgrades now refresh AQE-owned configuration safely. Existing MCP blocks can switch memory backends, generated AGENTS.md guidance updates inside explicit ownership markers, and user TOML, instructions, and hook groups remain intact.
  • Partial Codex installs are diagnosable. MCP, rules, hooks, and skills now report independent outcomes, so a malformed hooks file no longer hides the components that succeeded or prevents later skill installation.

Changed

  • Removed the unused duplicate init command implementation. The active CLI continues through the modular init handler, eliminating a second stale help and option surface.

[3.13.3] - 2026-07-29

Two independent quality-of-evidence fixes: learning capture could stop silently for days on a filesystem where WAL is disabled, and QE-Court shipped a default review panel that violated its own anti-collusion rule.

Fixed

  • Learning capture no longer stops silently when AQE_DISABLE_WAL is set. With that flag on, AQE tried to switch the database journal mode on every writable connection. That switch needs exclusive access, so any other process holding the database open — a stray MCP server, for example — made the attempt fail and take the whole persistence layer down with it. Hooks kept reporting success while nothing was being recorded, which hid the outage for days.

    AQE now only changes the journal mode when it is actually wrong (so normal operation never needs the exclusive lock), refuses to write in a mode you have declared unsafe rather than risking corruption, and — when something really is holding the database — tells you the exact command that finds it instead of guessing which process to blame.

  • QE-Court's shipped default panel violated writerIsNeverJuror (#576). The bundled config.json seated the defense and the jury on two tiers of the same vendor, which is exactly what the court's core anti-collusion rule forbids — so a brand-new project got an invalid panel with no user action. Worse, the rule could never have caught it: nothing turned the configured routing into a panel, so validation never ran outside its own unit test, and the config's options block was not wired to anything.

    The default panel is now genuinely cross-vendor (and keeps the deeper-review round on a different vendor from the jury, so escalation stays independent), validation is a required step before a court convenes, the options block actually takes effect, and the shipped config files are checked in CI so this cannot regress unnoticed. Reported by @pacphi.

Changed

  • The bundled statusline refreshes every 60 seconds instead of every 5. It reopened the learning database on every tick, adding constant pressure to the same lock the fix above depends on.

[3.13.2] - 2026-07-24

Stops short-lived learning hooks from repeatedly producing brain.rvf.corrupt-* and patterns.rvf.corrupt-* files. A busy project could accumulate thousands of these derived-cache artifacts while vector search repeatedly fell back to SQLite.

Fixed

  • Hook processes now close every RVF store before exiting ([#574]). Every aqe hooks invocation opened the shared pattern index and brain dual-writer, but the CLI had no teardown step. The native stores therefore exited without a clean close; the next hook found an unusable 162-byte store, quarantined it, rebuilt it, and repeated the cycle. Hook commands now dispose the reasoning bank and reset both RVF singletons after every action.
  • A duplicate opener can no longer break its own process's live RVF lock ([#574]). Recovery protected locks owned by other live processes but treated a lock containing the current PID as stale. Another initialization path in that process could then remove the lock and replace a store still in use. Every live owner is now protected; duplicate paths degrade safely to SQLite instead of moving a live store.

Changed

  • RVF hook cleanup is idempotent and fail-open. Partial initialization, optional native bindings, or an individual close failure cannot block the host editor or command. True stale locks remain recoverable after their owner exits.

[3.13.1] - 2026-07-23

Fixes four reported issues, three of which come down to the same thing: a tool told you something it had not actually established. Coverage analysis reported numbers it never measured, test generation claimed AI enhancement it never performed, and a security advisory reached users through a dependency they never asked for.

Fixed

  • Coverage analysis no longer reports numbers it did not measure (#569). On a Rust crate, coverage_analyze_sublinear returned 78.3% lines, 100% branches and 0% functions — none of it measured. It flagged #[cfg(test)] blocks as untested production code, cited line numbers past the end of the file, and analysed test files as coverage targets, all with a confidence score attached. Rust crates are now measured with cargo llvm-cov when it is available. When nothing can be measured, the result says so (estimated: true, measured: false) instead of presenting a guess as data.
  • test_generate_enhanced actually calls your LLM now (#567). The tool advertised AI-powered generation but the LLM router never reached the code path it runs, so it always returned the same generic scaffold regardless of how you configured your provider. It now routes through your configured model, and the result reports llmEnhanced so a silent fall back to templates is visible rather than something you infer from a suspiciously fast response. A broken provider (bad key, timeout) reports the fallback honestly instead of claiming enhancement it did not perform.
  • A HIGH-severity advisory no longer reaches consumers (#565). @huggingface/transformers was declared an optional peer dependency, but npm installs optional peers — so every install pulled in onnxruntime-node -> adm-zip and its advisory. It is now an explicit opt-in: install it yourself only if you want local in-process embeddings. Everyone using an embedding endpoint (the default) no longer carries the advisory.
  • codex is selectable through the LLM router. The provider existed and worked, but was missing from the router's provider list, so it could never actually be chosen.
  • Fixes now take effect immediately after an upgrade. Operation results were cached per project and keyed without the build version, so an upgraded install could keep replaying the previous version's answers for up to an hour — making a fix look like it had not worked. Set AQE_SESSION_CACHE_SALT to force a cold cache at any time.

Added

  • Per-agent LLM routing you can configure on disk (#568). Route individual agent types through different providers via an agentOverrides map in .agentic-qe/llm-config.json — a strong reasoning model for security agents, a free local model for mechanical ones — without changing your global default:

    {
      "defaultProvider": "ollama",
      "agentOverrides": {
        "qe-security-scanner": { "provider": "claude-code", "model": "opus" },
        "qe-mutation-tester":  { "provider": "ollama" }
      }
    }
    

    Entries are partial (unset fields keep their defaults), invalid entries are dropped with an explanation rather than failing startup, and credentials are never persisted here. See docs/guides/llm-provider-routing.md.

  • AQE_COVERAGE_NO_EXEC=1 — opt out of running build tooling. Measuring coverage means running your project's tests, which executes code from the analysed repository (cargo also runs build.rs; npx runs lifecycle scripts). That is what you want for your own code, but is worth being able to turn off when pointing the tool at something you do not trust. Existing coverage reports are still read; everything else degrades to a labelled estimate.

  • QE skills and lifecycle hooks for the Codex CLI. aqe init now installs three Codex-native skills — aqe-test-change, aqe-review-quality, aqe-plan-quality — under .agents/skills/, plus Codex lifecycle hooks in .codex/, and an AGENTS.md describing the repository's conventions. If you drive this project with Codex rather than Claude Code, the QE workflows are now available there natively instead of Claude-only.

  • Security scans state how deeply they looked. Full SAST is implemented for JS/TS only; other languages get cross-language pattern matching. Results now carry analysisDepth, so a zero-finding scan reads as "nothing matched a generic pattern" rather than "no vulnerabilities".

Changed

  • BREAKING (result shape): coverage_analyze_sublinear now returns null — not 0 — for any coverage metric that was not collected. lineCoverage, statementCoverage, branchCoverage and functionCoverage are all number | null. 0 now means a measured zero; null means unknown. Callers doing arithmetic or comparisons on these fields should handle null; check the new measured / estimated flags to tell the cases apart. This is deliberately a visible break rather than a silent wrong number.

[3.13.0] - 2026-07-18

Introduces QE-Court — an adversarial review court where a change is prosecuted by independent AI reviewers from different vendors, each with its own probe set, and a SHIP verdict must survive an escalating deeper review before it stands (SHIP / REMAND / BLOCK). It debuted by reviewing this very release — and blocked it, catching three data-loss/crash bugs a green unit suite had missed (all fixed below). This release also adds a Codex (GPT) provider so the court can seat a genuinely cross-vendor reviewer, a statistical significance gate for the self-learning flywheel, automatic memory.db recovery, and per-agent cost tracking.

Added

  • QE-Court — adversarial review as a verdict (/qe-court). Convenes independent, cross-vendor reviewers (Codex/GPT, Cognitum, Claude) against a diff/PR/test-suite; a passing grade must survive an escalating overturn round before it stands. Emits a signed court record with a three-valued verdict. The court's rules are enforced in code and verified by a runnable acceptance eval (aqe eval run --skill qe-court) — trust tier 3.
  • Codex CLI provider — run QE on your ChatGPT subscription. A codex provider (like the existing claude-code one) shells out to codex exec, so GPT-family models cost against your subscription rather than a per-token API key. Gives the fleet a cross-vendor engine for review diversity and fallback.
  • Statistical significance gate for the self-learning flywheel. A new accept/v1+sig promotion rule requires a candidate's held-out gain to be statistically significant (paired bootstrap CI > 0), not just larger by any amount — so the flywheel no longer promotes within-noise improvements.
  • Automatic memory.db recovery. If the learning database opens genuinely corrupt, AQE now restores the newest integrity-verified backup automatically and parks the corrupt file (never deletes it), instead of asking you to restore by hand. Deliberately conservative — a healthy database is never touched.
  • Per-agent cost attribution. The spend ledger now records which QE agent incurred each LLM charge, so cost can be broken down across the fleet.
  • Cognitum QE cost-Pareto benchmark (scripts/cognitum-qe-bench/). A self-contained harness that measures, per QE task, the cheapest model tier that clears the quality bar against api.cognitum.one — so tier routing is set by evidence. First finding: on these tasks the cheap tier matched or beat the frontier tier at 34× less cost.
  • Draft /v1/qe/verdict API specification for a future hosted QE-Court service.

Fixed

  • 4 HIGH-severity CVEs no longer reach consumers (#565). @huggingface/ transformers (which pulled a vulnerable onnxruntime-nodeadm-zip) is now an optional peer dependency, so a default npm install agentic-qe no longer installs it. Local/in-process embeddings still work when the package is present; endpoint-based embeddings are unaffected.
  • Three data-loss / crash bugs caught by QE-Court's own first review. (1) A subscription-provider subprocess exiting early could crash the calling process with an unhandled EPIPE; (2) the new auto-restore could tear the database under concurrent access or misdiagnose a healthy database on certain bind-mount filesystems and revert to an older backup — both fixed to be atomic, locked, and conservative; (3) a failed spend-ledger migration could silently stop recording spend, bypassing the budget cap. Plus witness-verification now fails closed by default and the flywheel gate rejects statistically under-powered samples.

Changed

  • The user-facing QE skill count is now 76 (adds qe-court), with 50 Tier-3 verified skills. CONTRIBUTING.md now clarifies that ruflo / claude-flow are development-time tooling, not runtime dependencies of the shipped package.

[3.12.3] - 2026-07-17

Fixes a bug that could silently switch off vector search — permanently. If an export of the RVF store was interrupted (a hook timing out, a session ending, a hard kill), it left behind a store file that AQE could neither open nor replace. Every later run fell back to SQLite without saying so, and only deleting the file by hand brought it back. One reporting project hit this three times in a day; this repository turned out to have been running degraded for nine days. Existing broken projects self-heal on the next run — no manual cleanup. Thanks to @pacphi for the detailed report (#563).

Fixed

  • An interrupted brain export no longer breaks the store (#563). Exports are now written to a temporary file and moved into place only once complete, so an interruption leaves your previous store untouched instead of destroying it. Abandoned temporary files are cleaned up on the next export.
  • Unusable stores are repaired automatically instead of silently disabling vector search (#563). When a store can neither be opened nor rebuilt over, AQE now sets it aside (as <name>.rvf.corrupt-<pid> — kept, not deleted, in case you want to report it) and rebuilds the cache from memory.db. This applies to brain.rvf, patterns.rvf, and the pattern-store path. Previously each of these degraded quietly, for every subsequent run.
  • RVF failures are no longer silent. Falling back to SQLite now logs why, rather than vanishing into an empty catch.
  • A live process's store is no longer at risk during lock cleanup (#563). Stale-lock recovery previously removed lock files unconditionally, which could break a store another process was actively using. Locks are now checked against their owning process and left alone when it is still running.

Added

  • Flywheel receipts are signed with the Cognitum platform identity (#562). The QE-policy flywheel now signs its evolve receipts with the same externally-verifiable platform key (f1ac28607da49ec1) used elsewhere, so all QE evidence — engine campaign and flywheel promotion — chains to one identity a verifier can attribute. Falls back to the local key when the platform identity is unavailable.

[3.12.2] - 2026-07-13

Billing-aware LLM execution. AQE could previously only bill the paid Anthropic Developer API (ANTHROPIC_API_KEY), even for users on a Claude Pro/Max plan that already covers Claude Code usage — and its declared budget caps were never actually enforced. This release adds a subscription execution path, real cross-process spend caps, transparent billing modes, and a metered-capped gateway provider. It also fixes aqe eval run, which had been scoring fabricated (mock) responses instead of real model output. See ADR-123.

Added

  • Run QE on your Claude subscription (AQE_LLM_PROVIDER=claude-code). A new provider shells out to claude -p and draws from your Pro/Max plan's shared usage instead of a pay-per-token API key. Worst case becomes "hit your plan limit and pause" rather than a surprise bill. The spawned CLI has all API-billing keys stripped from its environment so it can't silently revert to API billing.
  • Enforced spend budgets. --max-budget-usd (and AQE_MAX_BUDGET_USD) cap total LLM spend for a run; the cap is persisted to .agentic-qe/memory.db so it holds across a whole fleet of processes, not just one. Requests that would exceed the cap abort with COST_LIMIT_EXCEEDED before any spend.
  • Cognitum provider (AQE_LLM_PROVIDER=cognitum). An OpenAI/Anthropic- compatible gateway (api.cognitum.one) with authoritative per-request cost receipts, cloud embeddings, and a server-side hard spend cap.
  • Billing transparency. A one-line notice at startup and a new "LLM Billing" section in aqe health show how the active provider bills (pay-per-token / server-capped / subscription / local), so a paid API key is never a silent surprise.

Fixed

  • aqe eval run now makes real model calls. It previously defaulted to a mock executor that returned canned, keyword-matched responses, so eval results were fabricated. Eval now runs against a real provider by default (inheriting budget caps and provider selection), errors clearly when no provider is configured, and offers an explicit --mock flag for offline testing.
  • Budget caps are now actually enforced. The maxCostPerHour/Day settings existed but were dead code, and enforcement was bypassed on the primary routing path (HybridRouter). Both are fixed.
  • An explicit enabled: false for a provider is honored even when its API key is present in the environment (previously the key silently re-enabled it).

Changed

  • The multi-model consensus verification path now prints a billing warning when it uses an Anthropic API key, so that spend isn't silent either.

[3.12.1] - 2026-07-12

Makes aqe init non-destructive to configuration users already have in their project. Previously, running aqe init (e.g. after ruflo init) could overwrite a project's .claude/settings.json — clobbering a custom status line, an explicit includeCoAuthoredBy choice, user-tuned AQE_* environment variables, and even another tool's hooks. Init now merges rather than overwrites, preserves the user's values, and takes a one-time backup of the original file — the same treatment CLAUDE.md already received.

Fixed

  • aqe init no longer strips ruflo / Claude Flow hooks. The AQE hook-detection patterns were too broad (matching anything under .claude/helpers/ or any ruflo command), so re-running init in a project that had already run ruflo init deleted the user's hooks. Detection is now scoped to AQE's own hook markers, so other tools' hooks are preserved.
  • aqe init preserves a user's custom statusLine. Init only writes its own status line when none exists or the existing one is AQE's — a user's (or another tool's) custom status line is kept.
  • aqe init respects an explicit includeCoAuthoredBy setting. Init only sets the default when the user has not chosen a value.
  • aqe init preserves user overrides of AQE_* environment variables. Re-init fills in only the missing keys; values the user changed (e.g. AQE_LEARNING_ENABLED=false) are kept.
  • v3Configuration / v3Learning sections are deep-merged, so user-added keys in those sections survive re-init instead of being replaced wholesale.

Added

  • .claude/settings.json.backupaqe init now writes a one-time backup of the pristine original settings.json before modifying it (mirroring the existing CLAUDE.md.backup behavior). The backup is never overwritten on subsequent re-inits, so the original is always recoverable.

[3.12.0] - 2026-07-10

Adds a learning-integrity layer so the self-learning system can only promote what it can prove. Test-quality is now measured against a frozen, hash-pinned oracle benchmark; promotions are gated by the quality of their evidence (real test execution beats an LLM judge beats a structural heuristic), recorded as cryptographically-signed, replayable receipts, and re-checked against the exact frozen rule before they take effect. A new two-gate quality command (mechanical checks + an independent frontier-model judge) is exposed on both the CLI and MCP. Ships with a designed-experiment tool that measures — with real statistics — whether a given harness feature actually improves test quality or just adds cost. See ADRs 117122 and v3.12.0 release notes.

Added

  • aqe quality-gate CLI command and qe/quality/gate MCP tool — a two-gate quality verdict: a mechanical gate (the code must actually run and kill mutations) plus an independent frontier-model judge that checks the test against the spec. Returns a three-valued verdict (pass / fail / inconclusive) and degrades honestly to "inconclusive" when the judge is unavailable rather than guessing.
  • Frozen oracle anchor set — a hash-pinned benchmark of graded test items with a constant denominator, so a drop in the learning system's test-quality is detectable as a real regression instead of being hidden by a moving target.
  • Provenance-tiered promotion — every learning promotion now carries an evidence tier (test-execution > LLM-judge > structural heuristic), and a policy can require a minimum tier before anything is promoted.
  • Receipt-gated policy flywheel — retrieval-policy improvements are recorded as Ed25519-signed, replayable receipts with a compounding lineage, so every promotion is auditable, re-verifiable offline, and reversible.
  • Gate re-execution on promotion paths — before a promotion takes effect the frozen accept-rule is re-run on the sealed inputs, catching any promotion that was logged but that the rule would actually reject.
  • Designed-experiment harness tool (scripts/doe-run.ts + scripts/doe-aggregate.mjs) — runs a factorial screen (model × prompt × retrieval × scaffold) with replicates and a real main-effects ANOVA, so you can tell whether a harness feature helps reliability or is just cost. First screen found that heavy scaffolding lowers reliability and that retrieval adds no measurable quality on already-known tasks.

Fixed

  • Brain-export hook no longer leaks deadlocked background exports that could respawn, and database backups are hardened for virtiofs bind-mounts (a VACUUM-INTO backup path that avoids the WAL-corruption failure mode).
  • AQE_DISABLE_WAL / AQE_JOURNAL_MODE env override for SQLite journal mode, so environments prone to bind-mount WAL corruption can opt into a safer mode.
  • Pattern-lifecycle promotion now records and gates on provenance tier (additive column migration, conservative backfill).

[3.11.5] - 2026-07-07

A system-integrity sweep of the self-learning loop: dream-cycle insights now genuinely turn into reusable patterns instead of silently piling up, pattern usage stats are accurate again (no more double-counting or mid-session regressions), and the witness-chain audit trail, agent-topology tracking, GOAP plan execution, and SONA continual learning all had real dormant-code or data-integrity bugs fixed. See SYSTEM-INTEGRITY-AUDIT-2026-07-04 and the remediation plan for full findings and verification evidence.

Fixed

  • Dream-cycle insights now genuinely become reusable patterns — a gate in the concept-loading path meant the fix that lets detectGaps/ detectOptimizations/detectPatternMerges see real failure/success data only ever ran in manual tests, never in real scheduled dream cycles. Also fixed the mechanism that marks an insight "applied": it previously incremented a counter on the 3 newest insights on every successful task regardless of whether anything was actually promoted (proven live in production, with counts as high as 16) — it now only marks an insight applied when it's genuinely turned into a new pattern.
  • aqe learning stats reported the wrong pattern counts — Total and "By Domain" now come from the real pattern store instead of an incomplete vector-index count that silently excluded any pattern without an embedding.
  • Pattern usage was recorded twice per outcome, inflating usage counts and success-rate stats 2x; now written once.
  • Pattern lookups could silently fail after a name collision ("Pattern not found") because an internal id could go out of sync between the in-memory cache and the database; fixed for both pattern-store backends.
  • Learning stats could regress mid-session — reported totals could drop below the real historical count right after the first pattern-usage event in a session; now always reports the correct, non-decreasing total.
  • Witness-chain audit trail — cryptographic signing now covers all new entries, and a bug that silently broke chain verification for every entry after an archival operation is fixed, plus a new CI gate to catch regressions.
  • Agent-topology tracking (mincut) now reflects real agent activity instead of a constant placeholder reading, removing a false "critical" routing state that could occur on an empty graph.
  • GOAP plan execution now dispatches real domain-API calls for the majority of actions instead of always simulating (mocking) results.
  • SONA continual-learning cold start — the self-learning weight-update mechanism no longer needs 100 requests to accumulate within a single process lifetime before it can save its first update; progress now persists across restarts.
  • Assorted smaller integrity fixes: pattern-null (failure record) capture wasn't wired into the production learning path; a stale/expired daemon process could look "healthy"; a TTL bug caused several cache entries to live 1000x longer than intended.

Changed

  • Cleaned up dead data left over from now-fixed bugs (degenerate agent-topology snapshots, orphaned GOAP test-fixture rows, a corrupted insight-tracking counter) — internal only, no user-facing behavior change.

[3.11.4] - 2026-07-01

Better free local-model support, a tamper-evident guard for AQE's learning database, and a self-running dependency-security system — so known CVEs surface on their own instead of sitting unnoticed.

Local test generation now defaults to a code-tuned local model and skips the paid path when a cached pattern already fits. A new opt-in proof-gate lets you cryptographically verify that nothing tampered with memory.db across a sync or migration. And AQE now audits its own dependencies on a schedule and opens in-range security-fix PRs automatically. See ADR-116 (proof-gate), ADR-115 (dependency security), and the free-tier local-models guide.

Added

  • Free-tier local test generation — run test generation on a local Ollama model (default qwen3-coder:30b), with an objective "is this a real test?" check and a repair loop; a ruvLLM-style pattern cache skips the model entirely when a prior result fits, and the paid path is used only as fallback.
  • Local-model plumbing — unified AQE_OLLAMA_URL, adaptive Ollama timeouts, registered qwen3 models, and a capability-aware tool-routing guard so a model is only asked to use tools it actually supports.
  • Proof-gate (opt-in) — a tamper-evident SHA-256 hash chain over the memory.db kv write path: enable it for a sync/migration/publish window (AQE_PROOF_GATE=1) and verifyMemoryIntegrity() proves no write was mutated, reordered, or dropped. Off by default, fail-soft, single-store (ADR-116).
  • Dependency-security system — a daily scheduled consumer-POV npm audit that files a tracking issue on new HIGH/CRITICAL CVEs (even against unchanged, pinned deps), plus a weekly updater that opens small in-range security-fix PRs and refuses to drop optional platform binaries. npm run deps:audit / deps:update locally (ADR-115).

Fixed

  • @grpc/grpc-js HIGH CVE (CVE-2026-48068 / -48069, server-crash DoS) resolved by an in-range bump to 1.14.4.
  • Reduced advisory noise — in-range dependency updates cut moderate advisories from 29 to 7 (OpenTelemetry W3C-Baggage family and others), with all 15 optional platform dependencies preserved.

Changed

  • Default local test-gen model is now qwen3-coder:30b (code-tuned MoE), replacing the general-purpose qwen3:30b-a3b — lower latency and more reliable test output.

[3.11.3] - 2026-06-27

Tests and evals you can actually trust, cheaper model options, and a guard that keeps AQE's commands and outputs stable for your scripts.

AQE now grades a generated test by running it — against the real code (it must pass) and against deliberately-broken versions (it must catch them) — instead of checking for keywords. Test generation leads with durable tests (invariants, contracts, properties) that survive a rewrite, and quality reports add a mutation-score / regenerability signal next to coverage. See the new oracle-evals plan (ADR-113) and the conservation-layer policy (ADR-114).

Added

  • Oracle evals — skill evals run the generated test against a reference implementation plus seeded mutants; an assertion-less or wrong test is rejected.
  • Durable-first test generationqe-test-generation now emits invariants, contracts, and property-based tests first (with a "would this survive a rewrite?" check), keeping happy-path/mock tests as a labeled, disposable tier.
  • Regenerability gateqe-quality-assessment reports mutation score + a per-module regenerability score alongside coverage (warn by default, opt-in blocking).
  • Conservation guardnpm run verify:conservation + verify:skill-parity catch breaking changes to CLI commands, report output schemas, the dashboard API, and skill trees, with a deprecation policy so removals are deliberate and announced.
  • Cheaper model lanes — pick a budget or local model for test generation and prove it clears the oracle: npm run providers:health, eval:models, eval:live:*. See the cheaper-model guide.

Fixed

  • OpenRouter provider now works through the provider manager (it previously failed to route because it identified itself as openai).
  • Gemini provider default model updated to a current model (gemini-2.5-flash); the old default had been retired by Google. Supported-model list and pricing refreshed.

[3.11.2] - 2026-06-27

First-class C4 architecture diagrams generated straight from your codebase — with a confidence score so you know how much to trust them. AQE detects your components, the external systems they depend on, and their real relationships (from the code's import/call graph), renders standard C4 Mermaid you can paste into GitHub or an IDE, and exposes it through both the CLI and an MCP tool.

See the new C4 architecture diagrams guide.

Added

  • aqe code c4 <path> — generate Context / Container / Component C4 diagrams (Mermaid) for a repository, with --level context|container|component|all, --format text|json, and -o <file>.
  • qe/code/c4 MCP tool — the same generation for agents and IDEs, plus semantic search over previously generated diagrams.
  • Confidence gate — every diagram is scored high / medium / low (deterministic, no AI judging another AI) with the reasons, so an auto-detected diagram is never presented as ground truth. Large or under-segmented repos are flagged as drafts.
  • Real relationships from the Knowledge Graph — component arrows now come from actual import/call edges (AST), not name-based guessing.

Changed

  • C4 generation is consolidated onto a single engine. On a render failure it now reports the error instead of silently falling back to a weaker diagram.

Fixed

  • Knowledge Graph file reads can be scoped to a project root, so analyzing a repository outside the current working directory no longer trips the file-path safety guard.

[3.11.1] - 2026-06-25

Benchmark-driven deepening of the opt-in "cheap-first" test generation from v3.11.0. We ran real model-vs-model benchmarks scored by a real oracle (mutation kill-rate + coverage) and shipped only what the measurements earned: best-of-k generation, cross-model diversity, and a self-test Goodhart guard — plus a reusable adversarial-verification gate, MCP self-governance, and signed provenance for delivered findings. Everything stays opt-in and off by default.

See the new Darwin-QE Self-Learning guide for the benchmarks, what we learned, and how to use it.

Added

  • Best-of-k generation — tries a few diverse candidates and keeps the first that passes the objective check; the extra call happens only when the first one fails. Enable via freeTierBestOfK.
  • Cross-model best-of-k (opt-in) — draw those candidates from different model families (e.g. a local model + a cloud model) so they cover each other's failures. Measured ~+6 quality points over a single model. Configure with freeTierCandidateProviders.
  • Cheap-first lane broadened beyond test generation — now also covers requirements → BDD/Gherkin scenario generation (opt-in), with an off-topic relevance gate so generic boilerplate is rejected.
  • @ruvector/adversarial-verify — a host-agnostic blind-refuter verification primitive (N independent refuters, majority-kill, default-refuted on uncertainty) plus an opt-in verifyGate output gate that drops unverified findings before they're emitted. New agentic-qe/verification/adversarial-verify export.
  • MCP self-governance — a default-deny policy for AQE's own MCP tool surface (.harness/mcp-policy.json) with a CI gate that fails on any high-severity finding.
  • Cost-Pareto value scoring — rank models by quality-per-dollar (and compute the non-dominated frontier) from measured data, not vendor claims. New agentic-qe/routing/value-score export.
  • Witnessed finding delivery — delivered findings are recorded in the Ed25519 hash-chained witness log with fail-closed verification (tampering throws).
  • Graceful optional-module loading — native/optional dependencies now degrade instead of crashing when a platform binary is absent, with a CI "absent drill" that proves the degraded path (and never masks a real load failure).

Changed

  • Default free-tier model is now qwen3:30b-a3b (was qwen3:8b). A benchmark showed the 8B model is below the test-generation quality floor; the 30B clears it (~89% mutation kill). Set freeTierModel to fit your hardware — small-RAM users get escalation-only value. Only affects users who opt into the free tier.
  • Goodhart guard — only an objective check (real test run, coverage, mutation, schema) can lift routing confidence; a model's own self-authored "passing" test never does.

[3.11.0] - 2026-06-20

Run test generation on free local models first, falling back to paid models only when needed. This release adds an opt-in "cheap-first" path: a local model (Ollama, OpenRouter free tier, or any OpenAI-compatible endpoint) attempts test generation with an automatic repair loop, and only the hard cases escalate up to your normal LLM tiers — so most routine generation can run at $0. Every cheap-vs- escalated outcome feeds routing feedback, so model selection improves over time.

Off by default; nothing changes unless you opt in. Inspired by the "the harness matters as much as the model" economics from Ruv's MetaHarness Darwin Mode.

Added

  • Free-tier local test generation (opt-in). Enable with AQE_FREE_TIER=1 (or enableFreeTier in the test-generation coordinator config) to generate tests on a free/local model before any paid LLM call. Default model qwen3:8b. See the Free-Tier Local Models guide.
  • Configurable free-tier providers — local Ollama, cloud Ollama, OpenRouter free models, or any OpenAI-compatible endpoint (vLLM, LM Studio, Groq, …). API keys are read from named environment variables and never stored.
  • Repair loop — when the local model's first output isn't a valid test, the failure is fed back and it retries before falling back (configurable retries).
  • Automatic escalation — hard cases the local model + repair can't solve escalate up the existing model ladder (Haiku → Sonnet → Opus) via the router.
  • Self-learning routing feedback — free-tier outcomes feed the routing calibrator and escalation tracker, improving model-tier confidence over time.
  • agentic-qe/routing/free-tier package export for programmatic configuration.

Fixed

  • Restored @ruvector/ruvllm-* optional platform packages dropped from the lockfile by a Dependabot update, which could break npm ci for consumers. (#541)
  • Multi-file test-generation requests now correctly fall back to the full generation path so every requested file is covered (the free-tier path handles the single-file case).
  • Security bump of the transitive hono dev dependency. (#541)

Changed

  • Auto-escalation tracker is now ladder-configurable (generic over tier names) so a free local tier can sit below the paid tiers. Fully backward compatible — existing behavior and the default Claude ladder are unchanged.
  • QE framework evolved PACT → PACTS — adds a fifth principle, Structured (governance, observability, and explainability of agent behavior; measure confidence, not trust), inspired by DORA's research on AI-assisted delivery. Ships with a playbook + readiness-assessment guide. The skill id/dir holistic-testing-pact and schema slugs are unchanged (cross-repo stable); the output schema gains an optional structured dimension (non-breaking). PACT originated with Reuven Cohen (Agentics Foundation); PACTS adds Structured. (#545)

[3.10.9] - 2026-06-17

MCP server reliability and database-free completeness, all from community-reported issues (@nagoodman). The agentic-qe mcp command now serves real MCP clients, a stale-cache bug that made memory_delete look broken is fixed, database-free mode now reaches every editor's MCP config, and a new opt-in lets you install for a single platform without the Claude Code surface.

Added

  • --no-claude exclusive install modeaqe init --no-claude --with-<platform> suppresses the default Claude Code surface (.claude/, .mcp.json, CLAUDE.md, governance, hooks) so the --with-* flags become the only install targets — e.g. a clean OpenCode-only project. Opt-in; the default install is unchanged. (#532)

Fixed

  • agentic-qe mcp now works with programmatic MCP clients. The command double-spawned the server with inherited stdio, so a piped-stdin client received EOF right after initialize and never got tools/list. The server now runs in-process (like the aqe-mcp bin), and a failed startup exits non-zero instead of hanging. (#528)
  • memory_delete is no longer masked by a stale cached read. Delete worked, but the session cache served a stale memory_retrieve afterward (the tell-tale identical timestamp), making delete look like a no-op. Mutating tools now invalidate their domain's cached reads. (#535)
  • Database-free mode reaches every MCP config, not just OpenCode. --no-database now propagates AQE_MEMORY_BACKEND=memory to .mcp.json (Claude Code), Cursor, Cline, Continue.dev, Kilo Code, Roo Code, Windsurf, Codex, Copilot, and Kiro — so launching the server through any client no longer recreates .agentic-qe/memory.db at runtime. The default persistent backend is unchanged. (#533)

Changed

  • js-yaml dev dependency bumped to 4.2.0. (#540)

A database-free OpenCode install and a set of MCP stdio client-compatibility fixes (community contribution from @nagoodman), plus a dependency-security pass that clears two production high-severity advisories.

Added

  • Database-free install modeaqe init --with-opencode --no-database (alias --memory memory). Produces a fully working OpenCode install that writes nothing under .agentic-qe/: every persistence path (memory manager, RVF, code-intelligence hypergraph, fleet kernel, session/result stores) runs in-memory, while the server still boots the same subsystems (fleet, ReasoningBank, workers) so it stays healthy with all 14 domains. Opt-in; the default persistent mode is unchanged. (#530, #534)

Fixed

  • MCP stdio server is now spec-compliant for strict clients. Subsystem console.log output was leaking onto stdout and corrupting JSON-RPC framing, and initialize hardcoded the protocol version — both made strict clients (OpenCode, the official MCP SDK) fail with "Failed to get tools". Console output is now routed to stderr and protocolVersion is negotiated. Applies in all modes. (#527)
  • OpenCode provisioning now ships a loadable format. Agents and skills are converted at install time to native .opencode/agent/*.md and .opencode/skills/<name>/SKILL.md with per-agent permission frontmatter. (#529)
  • protobufjs and ws production CVEs. Cleared two high-severity advisories flagged by the supply-chain audit gate: protobufjs (GHSA-f38q-mgvj-vph7, GHSA-wcpc-wj8m-hjx6) → 7.6.4 and ws (GHSA-96hv-2xvq-fx4p) → 8.21.0, via overrides that stay within each package's current major.

Changed

  • OpenCode installs no longer copy non-loadable .opencode/tools/*.ts wrappers. They were never loadable by OpenCode's tool() API and are redundant with the MCP server, which exposes the same tools. (#531)
  • Bumped vite 8.0.9 → 8.0.16 (dev dependency). (supersedes #536)

Known follow-ups

  • #528 — make agentic-qe mcp run in-process (currently mitigated by invoking the aqe-mcp bin directly).
  • #532 — platform installs are additive, not exclusive.
  • #533 — propagate AQE_MEMORY_BACKEND=memory to all generated MCP client configs, not just opencode.json.
  • #535 — pre-existing MCP tool bugs surfaced during smoke testing.

[3.10.7] - 2026-06-12

A learning-integrity and supply-chain release. Two independent bugs were silently halting self-learning — the hook shim swallowed fatal native-binary errors, and the SONA learning engine treated reward feedback as a no-op — both now fixed. A new CI gate validates the published package the way a real user installs it, and the QE skill evaluation suite is back on current models.

Fixed

  • Self-learning silently stopping on a native-binary mismatch. The hook shim (aqe-hook.cjs) discarded all stderr and always exited 0, so a wrong-platform better-sqlite3 binary (e.g. a macOS build inside a Linux container) failed to open the learning database with zero trace — dropping every captured experience for days while appearing healthy. Fatal native-init failures are now teed to a throttled, durable .agentic-qe/hooks-health.log with a one-line fix hint, so the outage is detectable instead of invisible.
  • Reward feedback not changing SONA weights. Bumped @ruvector/sona 0.1.5 → 0.1.7, which fixes an upstream bug where feedback produced zero weight changes (and negative feedback failed to "unlearn"). AQE drives that learning path on every reinforced trajectory, so reward signals were effectively inert until now.

Added

  • Consumer-side supply-chain audit gate (CI). A new workflow packs the tarball, installs it into a clean consumer project, and audits from the consumer's perspective — on every dependency-affecting PR and push to main, not only at publish time. This catches override-masked vulnerabilities (where the in-repo npm audit reads clean but installers are exposed) before they merge.

Changed

  • QE skill evaluation model matrix refreshed to current models. All 54 skill eval suites, the eval templates, the eval JSON schema, and the npm-distribution copy moved off retired model IDs (claude-3.5-sonnet, claude-3-haiku) to claude-sonnet-4-6 + claude-haiku-4-5, with claude-opus-4-8 added as a capability ceiling for the seven high-stakes security / chaos / defect skills. Evaluations were previously pinned to model IDs that no longer resolve.

[3.10.6] - 2026-06-11

The Pattern Space cross-pollination release (#522): a quality review of a community framework (universal-pattern-space) surfaced disciplines worth turning inward on AQE itself — evidence-labeled findings, a real safety eval for the data-protection rules, drift-proofing for shipped agents, and benchmark honesty. Six ADRs (105110), each with a live verification record on #522.

Added

  • Evidence-class labels on every finding (ADR-105). QE findings now carry an evidenceClassEXECUTED (a command was run, output attached), STATIC (from coverage/AST/lockfile data), INFERRED (LLM reasoning), or CONJECTURE (heuristic). Quality gates block only on EXECUTED/STATIC; INFERRED routes to adversarial verification (ADR-102) before it can gate; CONJECTURE never gates. The validation_pipeline MCP tool exposes the class and a needsVerification queue. All 51 standard qe-* agents now ship an evidence-discipline contract.
  • Behavioral safety eval for the data-protection absolutes (ADR-106). The rules that protect memory.db (never rm a .db, always back up first, never claim a migration succeeded without verifying row counts) are now a pass/fail gate instead of prose. A deterministic engine asserts on agent trajectories, and a live model-judgment matrix runs the real model tiers (Claude haiku/sonnet/opus) against temptation scenarios — as task openers and mid-task — with an absolute 5/5 bar. All native tiers pass every cell; the run itself caught and fixed a false-positive in the harness. Wired into safety-eval.yml.
  • Shipped-agent invariant verifier + CI (ADR-107). npm run verify:invariants asserts every shipped qe-*.md keeps its non-negotiable sections (with real content, not keyword presence), that assets/ and .claude/ definitions haven't drifted, and that versions are consistent. Enforced on PR + release via invariant-check.yml. Caught real drift on first run.
  • Benchmark lineage registry + pre-registered rubrics (ADR-108). A docs/benchmarks/LINEAGE.md registry plus a rubric-before-data discipline: any judged benchmark commits its rubric (and the hash lands in every result row) before data exists, so post-hoc edits are detectable. Includes an antipattern list distilled from the external review.
  • Interaction benchmark for qualitative agents (ADR-109). Trust-tier-3 eval infrastructure for agents whose output is prose (reviewers, advisors): a reactive simulated developer, hidden-acceptance-test ground truth, and a non-same-family judge (OpenAI under test, Gemini judge) with scenario-clustered statistics. Validated with a live cross-family run.
  • Kept-nulls in the learning loop (ADR-110). When a learned pattern is applied and fails, the failure is now recorded as a first-class negative record (consolidated per context) instead of vanishing. Pattern retrieval surfaces these nulls and discounts patterns by context-matched failure density — so "worked elsewhere" no longer outranks "failed here."

Fixed

  • validation_pipeline MCP projection dropped the evidence class. The MCP handler flattened findings to a fixed shape that stripped evidenceClass; it now carries the class, optional artifact, and the needsVerification queue through the protocol boundary.
  • Learning-loop pattern guidance was recorded but never attributed. The engine now threads the patterns that guided a task into experience capture and a context fingerprint into pattern search, so failures attach to the right patterns and the null-discount weights in-context failures hardest.

Changed

  • Validation-pipeline gating is evidence-aware. A failed blocking step now blocks only on verified (EXECUTED/STATIC) findings; a step that fails purely on unverified inference downgrades to a warning and queues for verification rather than silently passing or hard-failing.
  • Database schema v10 adds the additive qe_pattern_nulls table (migration verified against a copy of the production database; all pre-existing row counts unchanged).

Notes

  • ADR-105's INFERRED path is in place but the validation pipeline is legitimately all-STATIC today; wiring LLM-backed domain findings to emit INFERRED is follow-up work.
  • ADR-109's scenario corpus is intentionally small (2) — the infrastructure is complete and validated; scaling the corpus for statistical power is follow-up.

[3.10.5] - 2026-06-10

The Fable 5 / harness-parity release (#520): the CLI's memory and fleet commands work for the first time, prompt caching actually engages, the self-learning pipeline stays clean under reasoning-heavy models, and two new capabilities land — adversarially verified QCSD reviews and competitive test-strategy tournaments. Seven improvements, each with its own ADR and a reproduction-first verification record on #520.

Added

  • aqe arena — competitive test-strategy tournaments (ADR-104, Phase 1). Strategies compete on real fitness: built-in operator mutants executed via node --test, real line coverage, and a deterministic suite-cost term. aqe arena run --target fixtures/arena-demo --seed 42 produces a ranked competitive array that reproduces byte-identically under the same seed; --evolve hill-climbs the winner; runs persist to memory.db (aqe arena list).
  • Adversarially verified QCSD reviews (ADR-102). The development-phase swarm now runs as a deterministic workflow: one finder per quality dimension, then 3 blind refuters per finding (majority kill, Loki-mode rules from ADR-074), then code-only synthesis. Reports contain only confirmed findings; killed findings are retained with their refutations. In the validation run, the gate filtered a factually-wrong finding that the old prompt-driven fan-out would have shipped.
  • Structured verdict contracts (ADR-103). Versioned, additive envelopes — RiskDecision, FindingVerdict, CoverageGap — with dependency-free validators and published JSON Schemas (schemas/*.schema.json). The quality_assess MCP tool now attaches a validated riskDecision envelope.
  • Tool-loop circuit breaker (ADR-100). When the same Bash command fails 3× consecutively the pre-command hook warns; at 5× it emits a block recommendation with a recovery hint (AQE_STRICT_TOOL_LOOP=1 upgrades to a hard deny). Success resets; an open breaker grants a probe after 2 minutes.
  • Nested-subagent readiness (ADR-101). Anthropic announced depth-5 nested subagents on 2026-06-09; AQE is ready the day the gate lifts: post-task hooks accept --parent-agent-id/--depth (validated, persisted into trajectory metadata for per-hierarchy-level learning), and a committed probe script (scripts/probe-nested-spawn-depth.mjs) detects the upstream rollout — current verdict: NO_AGENT_TOOL, denylist still active.
  • LLM judge benchmark harness (scripts/judge-benchmark.ts) with Phase-1 results.

Fixed

  • aqe memory / agent / task / team / pipeline CLI commands always failed with "Fleet not initialized". The CLI initialized a full kernel but never registered it with the shared MCP handlers' fleet state. A new bridge (adoptExternalFleet) gives both entry points one fleet state — these commands now work from the terminal for the first time.
  • Prompt caching was dead code (ADR-088 amendment). enableCache: true existed but never set cache_control; every advisor/LLM call paid full input price. The Anthropic provider now marks the system prompt as an ephemeral cache breakpoint, surfaces cacheRead/cacheCreation tokens, and bills them at the real 0.1×/1.25× rates in cost tracking.
  • Pattern embeddings were contaminated by extended-thinking blocks (ADR-099). Reasoning-heavy models (Fable 5 era) emit large scratchpads inside task results; these are now scrubbed (boundary-gated) at trajectory ingestion, distillation, embedding backfill, and query time — prose that merely mentions a tag survives byte-identical.
  • Fresh-install learning silently no-oped. persistTaskOutcome assumed middleware-created tables (captured_experiences, experience_applications); on a fresh .agentic-qe the whole post-task learning transaction failed silently. The hook path now ensures the canonical schema.

Changed

  • Devcontainer now mounts node_modules as a named volume and installs in-container, so Linux containers stop tripping over host (macOS) native binaries (contributors only; takes effect on container rebuild).
  • Setup docs and the devcontainer install script no longer pin the long-stale ruflo@3.5.18 (now ruflo@3 + global ruflo mcp start).

[3.10.4] - 2026-06-08

Two correctness fixes that keep a project's self-learning where it belongs and stop orphaned MCP servers from burning CPU, plus opt-in support for running your own local Nagual pattern hub and LLM judge.

Added

  • Optional local Nagual pattern hub + local LLM judge (opt-in). Point the cross-project knowledge hub at a locally-run nagual serve instance via NAGUAL_URL, and score pattern quality with a local Ollama-compatible model via NAGUAL_JUDGE_URL / NAGUAL_JUDGE_MODEL. When configured, pre-task analysis surfaces relevant cross-project patterns for complex tasks in QE domains. Entirely best-effort and disabled unless the env vars are set — no behavior change for existing users.

Fixed

  • Project learning was being written outside its own .agentic-qe/ (#516). Two root-resolution defects are fixed: (1) findProjectRoot() now prefers the nearest .agentic-qe instead of the topmost, so an ancestor store (e.g. ~/.agentic-qe, created by any aqe run from $HOME) no longer hijacks every descendant project and fragments its learning into $HOME; (2) the RVF substrate (patterns.rvf / brain.rvf) now resolves its location through the project root instead of a cwd-relative default, so running a hook, worker, or aqe command from a subfolder no longer scatters stray, orphaned stores.
  • Orphaned aqe-mcp server busy-looped at high CPU and ignored SIGTERM (#513). When the parent Claude Code session exited, the stdio MCP server was reparented and spun at 7098% CPU indefinitely, surviving kill (only kill -9 worked). Stdin EOF is now treated as terminal — the server shuts down gracefully instead of entering a reconnect busy-loop — backed by an idempotent shutdown path with a watchdog timeout and unref()'d background timers so an orphan can never linger.

[3.10.3] - 2026-06-03

Code-intelligence overhaul for the JS/TS ecosystem (#511) plus a critical fix for MCP domain tools hanging on a fresh install.

Added

  • TypeScript/JavaScript code intelligence with no typescript dependency. aqe code index / deps / impact / search now parse TS/JS/TSX using bundled tree-sitter WASM grammars, so they work out of the box on the entire JS/TS ecosystem — including AQE's own source. Previously every TS/JS file errored with "TypeScript is required for code analysis" and produced 0 nodes/edges unless the user separately installed the multi-megabyte TypeScript compiler. The compiler is still used automatically as a higher-fidelity path when present. Grammars are built reproducibly via scripts/build-grammars.sh.

Fixed

  • MCP domain tools hung forever on a fresh install. Every MCP tool that goes through the queen/router path (code_index, quality_assess, defect_predict, …) spun a CPU core and never returned the first time pretrained patterns were seeded — QEReasoningBank.initialize() recursed via storePattern() because the initialized flag was set after seeding instead of before. The CLI was unaffected (it calls domain services directly). Fixed the init ordering; as defense-in-depth the advisory pattern-search/routing step is now timeout-bounded so a future stall there can never block a tool call.
  • aqe code deps returned 0 edges on TS/JS repos (#511). The knowledge graph was kept in-memory only, so deps/search (separate CLI processes from index) always saw an empty graph. Nodes/edges are now persisted; relative import specifiers resolve to their file nodes so the dependency graph actually connects; and the dependency traversal no longer fabricates phantom cycles.
  • aqe code search returned 0 results even for present terms (#511). Indexed content was written with a {namespace} store option but read back without it (the #491 Bug 2 pattern), so every matched vector was silently dropped.
  • Code-intelligence graph is now shared by CLI and MCP. The graph is pinned to a fixed code-intelligence:kg namespace instead of the backend default, so a graph indexed by one tool is readable by the other and the init existence check finds it. index --incremental prunes a file's stale entities/edges, the FileReader cache is evicted before re-reading, and MCP code_index reports real symbol/relation counts (was always 0/0).
  • index is now honest about unsupported languages. It warns when files are indexed under a language with no dependency extractor instead of reporting edge counts that deps then shows as 0.
  • tree-sitter WASM grammars repaired. The bundled python/java/c#/rust/swift grammars were built with the pre-0.25 emscripten format and silently failed to load with web-tree-sitter 0.26 (falling back to regex). Rebuilt with the matching toolchain so they load correctly.

Changed

  • Lint debt cleanup. Removed dead imports across the tree, wrapped case-clause declarations, documented intentional rule violations, ignored src/_archived, and aligned the bounded-context count metadata (1072 → ~472 lint problems). No behavioral changes.

[3.10.2] - 2026-06-02

Self-learning hardening release with two critical hook/dream fixes reported by users.

Fixed

  • Task trajectories were silently recorded as failed (#508). The aqe init-generated PostToolUse hook ran post-task … --success --json, but --success was declared as a value-taking option, so Commander consumed the following --json as the success value — every qe_trajectories / captured_experiences row was written with success=0, and no --agent was passed so each row recorded agent='unknown'. Because pattern distillation groups by agent/domain/success, Task-tool trajectories were unpromotable and the pattern count stayed pinned near zero. The --success option is now optional-valued (a bare --success parses true), and the generated hook passes real agent attribution + description. Existing installs: re-run aqe init (it detects and replaces AQE hooks) to pick up the corrected hook.
  • Dream-scheduler SessionStart readout was perpetually stale (#509). After ADR-094 moved dream cycles to the kernel scheduler, the dream-scheduler:hook-state row that SessionStart reads was only ever incremented by the post-task hook and never reset by the entity that dreams — so lastDreamTime stayed null and the pending-experiences counter grew without bound. The kernel DreamScheduler now reconciles that row after each successful cycle.
  • MCP unknown-tool errors lost their JSON-RPC code. A tools/call for an unknown tool surfaced Internal error: [object Object] instead of a proper JSON-RPC -32601; now returns the correct coded error.
  • Failure-based pattern deprecation never fired. checkDeprecation read a consecutive_failures column that the row mapper dropped, so a pattern that kept failing was never deprecated for failures. The column is now surfaced.
  • Routing confidence was diluted by broad domain detection. The domain-match score divided by the full count of detected domains (712 per task), washing out real matches; the denominator is now capped, recovering confidence on broad multi-domain tasks (tunable, ranking preserved).

Added

  • Importance-weighted forgetting protection (EWC++). Confidence decay and stale/age deprecation are now weighted by pattern importance (success rate × usage), so proven high-value patterns resist being crowded out by an influx of new low-value ones. Reversible via exported constants; low-importance patterns are unaffected.
  • Contradiction detection in consolidation. Two experiences with the same context but opposite outcomes are no longer merged — the lower-quality loser is suppressed from retrieval (even if previously applied) so it can't poison recall.
  • Self-learning verification harness (npm run benchmark:self-learning) — proves the learning stores actually persist what they claim, survive a restart, and that aggregators agree, with an isolated-temp-store negative control.
  • Real MCP protocol + tool-parity smokes (npm run mcp:validate, npm run mcp:parity) — boot the real server and validate the initialize / tools/list handshake against the MCP spec; replaces the previous no-op mcp:validate.
  • Resilient hook shim (.claude/hooks/aqe-hook.sh) — keeps init diagnostics out of the Claude Code transcript and guarantees a hook never blocks a turn.
  • Pretrain-from-history bootstrap (npm run pretrain:history) — seeds the pattern store from the repo's own git commits so a fresh project starts non-empty and project-specific.
  • RaBitQ 1-bit signature utility (src/shared/utils/rabitq.ts, npm run benchmark:rabitq) — 32× index-memory reduction for vector similarity (utility only; not yet wired into a retrieval path).
  • Plugin contract smoke (npm run plugin:smoke) — machine-checkable structural contract for the agentic-qe-fleet marketplace bundle.
  • ADR-098 documenting the learning-store & routing hardening decisions.

Changed

  • aqe init now installs a resilient hook shim and routes hooks through it. A cross-platform Node shim (.claude/hooks/aqe-hook.cjs) is copied into each project, and generated settings.json hooks run node .../aqe-hook.cjs <cmd> instead of npx agentic-qe hooks <cmd>. The shim keeps init diagnostics out of the Claude Code transcript, guarantees a hook never blocks a turn, prefers the project-local install (falling back to npx for npx-only setups). Re-running aqe init migrates existing npx-based hooks to the shim form (no duplicates).
  • Router state-encoding hardened with a regression guard (audit of two upstream router bugs — confirmed not present in AQE).

[3.10.1] - 2026-05-22

Changed — behavioral

  • ADR-043 LLM router is now actually wired. The HybridRouter from ADR-043 and the per-service LLM-enhancement branches from ADR-051 were implemented previously but never injected into the production swarm path. Domain services accepted llmRouter as an optional dependency, but no caller passed one — so isLLMAnalysisAvailable() returned false everywhere and the analyzeXxxWithLLM() branches in 15 service paths across 11 LLM-enhanced domains were unreachable.
    • The kernel now constructs a HybridRouter singleton during initialize() (auto-enabled when any provider API key is in env or the project's .agentic-qe/llm-config.json explicitly enables a provider) and forwards it through every domain factory to its services. MCP standalone tools resolve the same singleton via getSharedLLMRouter() so kernel-mode and MCP-mode share one router instance (single cost tracker, cache, circuit breaker).
    • Behavioral consequence: fleets booted with ANTHROPIC_API_KEY, OPENAI_API_KEY, OPENROUTER_API_KEY, GOOGLE_AI_API_KEY, GEMINI_API_KEY, or GOOGLE_API_KEY in env will now route LLM-enhanced analysis through that provider — previously the same fleet ran zero LLM calls from the swarm path regardless of provider config.
    • Three opt-out mechanisms, in order of preference:
      1. AQE_LLM_ROUTER_DISABLED=1 env var (no code change required)
      2. KernelConfig.llmRouter: { enabled: false } (programmatic)
      3. Unset the relevant provider keys in env
  • aqe llm config --set now persists. Previously a module-level let with a // would be persisted in real implementation comment — settings evaporated with the process. Writes now go to .agentic-qe/llm-config.json and survive a process restart. The file is apiKey-stripped on write so secrets can't end up in version control. Attempting aqe llm config --set apiKey=... now errors loudly pointing to the env vars users should use instead.
  • Gemini provider accepts GOOGLE_API_KEY in addition to GOOGLE_AI_API_KEY and GEMINI_API_KEY — covers users with the conventional Google API key name without requiring an env alias.
  • HybridRouter fallback chain bug fixes (surfaced by the rule-based E2E test):
    • executeWithFallback previously hardcoded ['claude', 'openai', 'ollama'] as the only fallback providers; users with only GEMINI_API_KEY (or openrouter/azure/bedrock) had no fallback when the routing-rule's chosen provider was unavailable. Fixed: now includes the user's defaultProvider automatically AND honors all 7 ExtendedProviderType providers in the fallback chain.
    • A non-retryable error from one provider (e.g., Claude "invalid x-api-key") previously short-circuited the entire fallback loop; the request would fail even when other providers were available. Fixed: non-retryable errors now skip the retry-delay but continue to the next fallback entry.
  • Init observability: kernel now publishes kernel.llm-router.init-failed and kernel.llm-router.init-no-provider events on the event bus when router construction fails or no provider is available. Monitoring can subscribe to catch silent regressions.

Verification

End-to-end round-trip verified on 2026-05-21 against Gemini (gemini-2.5-flash), OpenAI (gpt-4o-mini), and OpenRouter (openai/gpt-4o-mini). 5 real-provider E2E tests, 16 behavioral integration tests, 17 structural wiring tests, 110+ unit tests. See tests/e2e/llm-router-real-providers.test.ts (gated by AQE_LLM_E2E=1), tests/integration/llm-router-wiring.test.ts, tests/integration/llm-router-behavioral.test.ts.

Audit hardening

A qe-devils-advocate audit on 2026-05-21 surfaced 10 issues post-initial-wiring: silent billing regression, 2 unwired MCP tools, decorative MCPToolContext field, split router singletons (MCP vs kernel), silent error swallowing, two real HybridRouter routing bugs, missing behavioral tests, miscounted services, silent apiKey drops, undocumented env precedence. All 10 addressed before merge. See ADR-043 "Audit findings" section for details.

[3.10.0] - 2026-05-20

A feature release adding an optional external embedder endpoint for AQE's semantic vector layer. When set, AQE skips loading @huggingface/transformers in-process and routes feature-extraction through an OpenAI-compatible POST /v1/embeddings endpoint — eliminating duplicate model loads in ruflo/ruvector co-deployments and per-hook cold-load latency. Closes the feature request in #503 (ADR-097). Followed by a hardening pass closing 11 findings from an internal devil's-advocate audit before merge.

Added

  • Optional external embedder endpoint (#503, ADR-097). Set AQE_EMBEDDER_ENDPOINT=http://host:port or unix:/path/to.sock (or EmbeddingConfig.endpoint) and AQE routes vector computation to an OpenAI-compatible /v1/embeddings service. Default unset = no behavior change — current in-process Xenova/all-MiniLM-L6-v2 path is unchanged.
    • OpenAI wire format (encoding_format: 'float' pinned) — verified end-to-end against llama-server with all-MiniLM-L6-v2.Q8_0.gguf; expected to work against TEI / vLLM / Ollama / LocalAI / LM Studio / OpenAI given they all advertise the same shape (unverified until a real-provider integration test is added per provider).
    • HTTP and HTTP-over-Unix-socket transports (one protocol, two transports — no NDJSON fork).
    • Startup probe asserts dim === 384 and computes a stable identity fingerprint of a canary embedding. Persisted to memory.db kv_store so cross-run model drift surfaces as a loud warning on next boot.
    • Circuit breaker trips at 3 failures in a 60s window; on recovery the cached identity is invalidated so the next embed re-probes (endpoint restarts often coincide with model swaps).
    • TLS knobs (ca, cert, key, rejectUnauthorized, servername) passthrough for self-hosted HTTPS endpoints — no need to set NODE_TLS_REJECT_UNAUTHORIZED=0.
    • Bearer auth via AQE_EMBEDDER_TOKEN env (env-only — URL userinfo is stripped and warned at construct).
    • Hard-fail on error — no silent hash fallback. Hash and transformer embeddings are not comparable; mixing them in the same HNSW index silently degrades recall forever.
  • ADR-097 — External Embedder Endpoint (OpenAI-Compatible). Documents the wire-format choice, hard-fail correctness invariant, identity fingerprint scheme, and the per-caller audit table showing all 12 embed-callers are non-poisoning under endpoint mode.
  • New tests/integration/embedder-endpoint-llamacpp.test.ts — live-server integration suite gated on AQE_LLAMA_EMBED_URL. Six tests against real llama-server: probe stability, single + batch embed (50 inputs), lazy-probe gate, dim-mismatch fail-loud, semantic relatedness check.

Fixed

  • sqlite-persistence.ts backfill no longer poisons the HNSW index. When the external embedder endpoint is configured and fails, the backfill loop previously substituted hashEmbedding() for the remaining patterns — silently writing non-comparable vectors next to transformer vectors. Now re-raises and aborts the batch under isUsingEndpoint().
  • qe-reasoning-bank.embed() propagates errors under endpoint mode. The fail-soft hash fallback for ARM64 ONNX compatibility is preserved for the in-process path but suppressed when an endpoint is active.
  • True TCP-connect timeout. Connect-phase timeout now fires at the socket layer; previously it was req.setTimeout (an idle-after-write timeout) so SYN blackholes hung for the OS default ~75s instead of the documented 5s.
  • Identity probe is gated. EmbedderEndpointClient.embed() now lazily runs probe() on first use with in-flight dedup (20+ concurrent embeds share one probe). Closes a path where the dim/identity boundary check could be bypassed by direct client construction.
  • Endpoint URL userinfo redacted from logs. Credentials passed via URL (against the env-only convention) are stripped at parse and warned.

Changed

  • Embedding cache key is now namespaced by mode (endpoint:<fingerprint>:<text> vs inproc:<text>). Flipping between endpoint and in-process within a process can no longer return a vector computed under the wrong mode.

[3.9.36] - 2026-05-19

A hotfix release closing the self-learning routing loop reported in #499 by Jordi. The route hook's qWeight was structurally pinned at 0: the producer (updateHookRouterQValue) only fired from post-task gated on the pre-task bridge, so on real projects routing_outcomes accumulated 100+ rows while rl_q_values stayed at ~2 — the consumer side ADR-095 wired up had nothing to read. Q-learning never influenced routing. ADR-096 documents the three-part fix that ships in this release.

Fixed

  • route hook's qWeight was structurally pinned at 0 (#499). Three coordinated changes:
    • The Stop-hook post-route now trains rl_q_values when it resolves a routing_outcomes sentinel, deriving the same state_key the route hook used at insertion time. The high-volume routing surface now produces Q-signal in addition to consuming it.
    • post-task no longer drops Q-updates when the pre-task bridge is absent — direct Bash/Edit sessions and Task-tool runs where pre-task didn't fire now train Q from the task description. Adds a new --description CLI option to aqe hooks post-task so the PostToolUse hook can pass tool_input.description.
    • The Q-learning state_key collapsed from 4-dim (taskType|priority|domain|complexityBucket) to 3-dim (taskType|priority|domain). The previous length-keyed bucket fragmented semantically identical tasks across cells, so QWEIGHT_RAMP_VISITS=20 was rarely reached per cell. Convergence is now ~11× faster for a given (taskType, domain) pair.

Added

  • ADR-096 documents the producer/consumer alignment contract and the state-key shape decision. The three call sites (routing-hooks.ts post-route, task-hooks.ts post-task, qe-reasoning-bank.ts:530) must agree on (deriveTaskType, detectQEDomains[0], 'normal') — regression test tests/unit/cli/commands/route-q-loop-closure.test.ts fails the build if a future refactor desynchronizes them.
  • aqe hooks post-task --description <desc> option for Task tools that want to train Q without writing a pre-task bridge.

Changed

  • buildRoutingStateKey parameter shape (3-dim, no complexityBucket). deriveComplexityBucket stays exported and is still computed for the pre-task bridge payload (kv_store schema compatibility) and any downstream telemetry — marked @deprecated for state_key construction only.
  • Existing rl_q_values rows written under the 4-dim key shape become orphans; new lookups won't match them. Field reports show installs have ~2 such rows at most (the loop was broken so no real Q-data accumulated), so no migration ships. If you have substantial 4-dim data, a one-shot UPDATE rl_q_values SET state_key = ... stripping the trailing |N segment is straightforward.

[3.9.35] - 2026-05-19

A test-infrastructure release. Restores ESM subpath imports of HnswAdapter (PR #497), and starts dismantling the cumulative-growth pattern that has been timing out fork workers on qe-reasoning-bank.test.ts and aqe-learning-engine.test.ts across multiple recent publish workflows (issue #448 steps 2 + 3). No production-code behavior changes.

Fixed

  • import 'agentic-qe/kernel/hnsw-adapter' threw ERR_PACKAGE_PATH_NOT_EXPORTED (#497). The compiled file shipped in dist/kernel/hnsw-adapter.js, but the subpath was missing from the exports map. Adds the missing entry alongside ./kernel.
  • Vitest fork workers timed out on the heaviest learning tests (#448). Two interventions land together: (1) split qe-reasoning-bank.test.ts (1019 → 386 lines core, + utilities and feedback-loop companions) and aqe-learning-engine.test.ts (622 → 366 lines core, + patterns and factory companions) so each thematic group runs in its own sequential fork; (2) release module-level singletons between tests — clearEmbeddingCache() + a new _resetWitnessChainForTests() in afterEach, resetInitialization() in afterAll — so per-test memory growth doesn't compound across the file.

Changed

  • test:unit:fast exclude list now also carries the two new heavy split files (qe-reasoning-bank-feedback-loop.test.ts, aqe-learning-engine-patterns.test.ts). The two cheap split files (*-utilities.test.ts, *-factory.test.ts) are included in the fast lane and restore coverage that was previously dark.

Added

  • tests/integration/package-exports.integration.test.ts — a contract test that pins each declared subpath in the package.json#exports map. Future regressions of PR #497's class fail this test instead of breaking consumers' imports silently.

[3.9.34] - 2026-05-18

A reliability release fixing unbounded growth of the on-disk vector index. Field reports observed patterns.rvf reaching 59 GB on a fresh clone (and regrowing to the same size within 15 minutes of truncation), exhausting disk and breaking git operations, Vite dev servers, and npm cache clean. v3.9.27 fixed one init-time leak (#478) but never addressed the underlying append-only growth, and createHybridBackendWithTimeout() still used a Promise.race-bounded init that could not actually cancel the leaked write (#495).

Fixed

  • Sibling init runaway in createHybridBackendWithTimeout() (#495). v3.9.27 fixed ReasoningBank.initialize() with an AbortSignal but explicitly deferred the same fix for HybridMemoryBackend.initialize() — and the field report came in: a single hooks session-start invocation ran 14 min and grew patterns.rvf to ~20 GB at ~12 MB/s. The Promise.race timeout fired after 5 s but had no way to actually stop the underlying init; the dispose-after-resolve mitigation never ran because the init never resolved. Threaded an AbortSignal through HybridMemoryBackend.initialize() and UnifiedMemoryManager.initialize() with signal.throwIfAborted() checks at each await seam. createHybridBackendWithTimeout() now drives the 5 s timeout via an AbortController instead of Promise.race, so an abort actually cancels the work.
  • patterns.rvf grows without bound (no upstream issue — field report). The RVF format is append-only: every ingest() and delete() writes a new segment, and old data accumulates as dead space until compact() is called. Nothing in the codebase ever called compact() against patterns.rvf. Three fixes ship together:
    1. Post-dream compaction — the kernel-side DreamScheduler now runs a threshold-gated compact() after each dream cycle. Idle cycles are nearly free (only a status() call when below the threshold).
    2. Boot-time size guardgetSharedRvfAdapter() runs compact() once per process when the file is oversized (≥ 256 MB) or fragmented (deadSpaceRatio ≥ 0.30). One-shot recovery for installations already in the bad state.
    3. Bounded SQLite→RVF backfill — when an empty patterns.rvf opens against a populated SQLite DB, the backfill now caps to the top-1000 most-recently-used embeddings (was: every historical row, which is the mechanism behind "regrew to 59 GB after : > patterns.rvf").
  • brain.rvf had the same problem and zero compaction. Same write rate as patterns.rvf (one append per storePattern() via RvfDualWriter). RvfDualWriter.compact() now exists and is called from the same post-dream path. Native compact() is a no-op on a clean file, so the cost is bounded.
  • Race against meta-learning during compaction. Post-dream compact now runs sequentially with the rest of the cycle instead of fire-and-forget, so the meta-learning step never races against compact's exclusive RVF lock.

Added

  • RvfStatus.deadSpaceRatio surfaced on the wrapped native adapter, and RvfNativeAdapter.compact() now returns reclaim stats (segmentsCompacted, bytesReclaimed, epoch) instead of void. Used by the new compaction paths and visible to anything that already calls getStats().
  • Three env knobs for operators — no rebuild needed:
    Variable Default Purpose
    AQE_RVF_SIZE_GUARD_BYTES 268435456 (256 MB) Boot + post-dream compact trigger
    AQE_RVF_DEAD_RATIO_THRESHOLD 0.30 Boot + post-dream compact trigger
    AQE_RVF_BACKFILL_LIMIT 1000 Cap on SQLite→RVF replay after truncation
  • SQLitePatternStore.getRecentEmbeddings(limit) — ordered by last_used_at DESC, used by the bounded backfill path.
  • 24 new unit tests covering the decision logic, integration helpers, dual-writer compact, and backfill cap.

[3.9.33] - 2026-05-18

A dependency-cleanup and supply-chain-security release. npm install agentic-qe now pulls ~480 fewer transitive packages, ships with zero high/critical CVEs in the consumer install (was 5 in v3.9.32 — masked from in-repo audit by root-only overrides), and emits no ERESOLVE peer warnings. Two new CI gates make future regressions of this class impossible to ship.

Fixed

  • Critical CVE chain eliminated (@xenova/transformersonnxruntime-webonnx-protoprotobufjs <=7.5.5). Migrated to the maintained successor @huggingface/transformers@4.2.0, which depends on protobufjs ^7.2.4 directly with no onnx-proto middleman, so the version range resolves cleanly to the patched line. End-user npm audit now reports 0 vulnerabilities (was 4 high + 1 critical including arbitrary code execution GHSA-xq3m-2v4x-88gg).
  • Self-learning consolidation lastUsedAt parsing (#493). Bridge-mining and pattern consolidation rehydrate Date fields at all kv-read seams so the loop no longer silently drops freshly written experiences.
  • 6 high-severity CVEs in @typescript-eslint v6 chain (via minimatch). Bumped the dev-side toolchain to @typescript-eslint@8.59.3.

Changed

  • @claude-flow/browser and @claude-flow/guidance are now optional peer deps (was optionalDependencies). Together these no longer pull the internally-inconsistent @claude-flow/cli@3.6.x transitive chain that was the source of all ERESOLVE warnings. Users who want either feature install explicitly — aqe init (see Added) now tells you how.
  • web-tree-sitter 0.24 → 0.26 (Parser API moved onto the Parser class; compatibility shim makes us work against both surfaces).
  • @typescript-eslint/{eslint-plugin,parser} 6 → 8, commander 12 → 14, esbuild 0.27 → 0.28, @types/node 20 → 25.
  • Lockfile refreshed: vitest, @vitest/coverage-v8, axe-core, better-sqlite3, jose, msw, ora, tsx, yaml to current patches.

Added

  • Optional add-ons hint in aqe init. After a successful init, when @claude-flow/browser or @claude-flow/guidance is not installed locally, the CLI now appends a one-line install command for each — so opting in doesn't require reading the README. Skipped silently when both are present.
  • security-audit job in CI (optimized-ci.yml). Blocks PRs on high/critical CVEs in production deps; warns on dev-dep CVEs. Same gate also runs in npm-publish.yml.
  • Consumer-side audit gate (consumer-audit job, npm-publish.yml). Packs the local build, installs the tarball into a fresh tmp project, and runs npm audit there — closing the gap where root-only overrides mask consumer-facing vulns from in-repo audit. Now a needs: of the publish job, so a CVE invisible to our repo audit still blocks publish.
  • Post-publish consumer audit (post-publish-canary.yml). Same audit against the freshly-published registry tarball as a non-blocking safety net; opens an auto-labelled P1 issue on findings.

[3.9.32] - 2026-05-17

Fixes the chain of four bugs reported in #491 (Jordi Izquierdo) that left the self-learning consolidation loop dead end-to-end on v3.9.31, plus the release-process gaps that let those bugs ship in the first place. After this release, aqe learning loop-health populates as expected on a vanilla install and the learning-consolidation worker actually consolidates instead of silently failing every tick.

Fixed

  • Self-learning consolidation loop dead on fresh installs (#491). Four stacked bugs broke the experience capture → bridge → mine → consolidate pipeline end-to-end:
    • The MCP-hosted daemon constructed its WorkerManager before the kernel existed and was never told about the kernel once fleet_init built it — so every domain-dependent worker tick failed with <domain> not available (14+/cycle). setKernel and a new setMemory are now public on the WorkerManager interface and handleFleetInit wires them in after plugin load.
    • LearningCoordinator wrote experiences with namespace: 'learning-optimization' but HybridBackend's read methods hard-coded defaultNamespace='default', so the coordinator could not read its own writes and mineExperiences returned 0 for every domain. MemoryBackend.get/has/delete/search now accept RetrieveOptions { namespace? }, symmetric with the existing StoreOptions.namespace; all 15 read sites in LearningCoordinator pass the matching namespace.
    • JSON.stringify serialized Experience.timestamp to an ISO string but JSON.parse didn't rehydrate; TimeRange.contains did string >= Date which coerces to NaN — so even with the namespace fixed, the time-window filter dropped every experience. getExperiencesByDomainAndTime now coerces to Date at the kv-read boundary.
    • LearningConsolidationWorker.doExecute called recordLoopHealth(success:true) after collectPatterns(), which throws on empty installs — so the dashboard showed never-ran permanently. The worker body is now wrapped in try/catch/finally matching the bridge's drainSafe pattern; liveness reports on both the success and failure paths.

Added

  • Daemon-runtime release gate (#491). The pre-publish flow now runs the daemon-runtime seam test suite alongside the existing fast unit tests. New test:integration:fast script runs four focused integration tests in ~6 seconds:

    • fleet-init-wires-daemon.test.ts — proves the kernel→worker wiring is alive after handleFleetInit.
    • workers-reach-domains.test.ts — iterates every registered worker and asserts each declared targetDomain resolves to a real API. Catches the Bug 1 class for all 11 workers in one test.
    • coordinator-roundtrip.test.ts — full recordExperience → mineExperiences round trip through the real HybridMemoryBackend. Catches the namespace and timestamp bugs together.
    • bridge-end-to-end.test.ts — existing bridge fan-out coverage.
  • Liveness contract test for LearningConsolidationWorker. Verifies recordLoopHealth fires on both success and throw paths, and that a memory-backend hiccup inside the liveness recorder cannot shadow the worker's real error.

  • A23 daemon-liveness assertion in the init-corpus release gate. Opt-in per fixture via the new expectDaemonLiveness manifest flag; spawns the cleanroom daemon post-init, waits the configured window, and asserts zero domain not available lines on stderr before killing the daemon. Enabled on the tiny-ts fixture with a 15-second window as a pilot. Catches the class of regression that aqe init alone cannot surface, since the daemon-runtime seam only opens at daemon startup.

Changed

  • MemoryBackend.get/has/delete/search now accept an optional RetrieveOptions { namespace? } second argument. Backward-compatible: undefined still routes to defaultNamespace. Any caller that was using InMemoryBackend's undocumented positional namespace?: string parameter (not on the MemoryBackend interface) needs to switch to the options form.

  • package.json defines test:integration:fast (the new release gate's input) and test:integration (full integration suite for local development). .github/workflows/npm-publish.yml adds a new integration-tests-on-tag-sha job wired into the publish needs/if conditions.

[3.9.31] - 2026-05-15

Self-learning loop ships. Closes issues #480, #486, #487, #488 and introduces two architectural decision records (ADR-094, ADR-095). With this release, the QE fleet's pattern catalog actually diversifies in practice instead of converging on whatever pattern won first.

Fixed

  • post-edit hook never triggered dream cycles (#480). The hook was initializing dreamTriggered = false as a literal and never calling checkAndTriggerDream — so the experience counter grew monotonically but the dream loop never fired. Operators saw dream_insights.applied stuck at 0 forever. The hook now correctly invokes the trigger and surfaces the full result shape (reason, insightsGenerated, insightsApplied) in JSON output.

  • Q-learning never received signal for low-confidence prompts (#487). The pre-task hook gated the routing-bridge kv write on selectedPatternIds.length > 0, which silently dropped the bridge for every low-confidence prompt. Post-task's Bellman update then had no state to update, and rl_q_values never populated despite routing decisions actively happening. The gate is removed; the bridge now writes whenever the task has a description, regardless of pattern match count.

  • qe_pattern_usage audit table stayed empty in production (#486 Gap B). Two parallel writers existed for pattern usage: the canonical SQLitePatternStore.recordUsage (correctly wrote BOTH the audit row and the qe_patterns columns inside one transaction) and an inline UPDATE in the hook flow (skipped the audit INSERT). Operators saw usage_count climbing while qe_pattern_usage had zero rows. Extracted a single-writer helper recordPatternUsage; both call sites now delegate to it. The invariant COUNT(*) FROM qe_pattern_usage = SUM(qe_patterns.usage_count) is now structurally enforced.

Added

  • Kernel-side dream cycles (ADR-094, #488 Phase 2). Dream cycles used to run in short-lived hook subprocesses, holding the SQLite write transaction for up to 10 seconds while other writers queued behind. Errors went to stderr where Claude Code's hook reader swallowed them. Now the existing DreamScheduler (built in v3.7 but never wired) runs from QEKernelImpl.initialize(). Hook subprocesses keep only the cheap experience-counter bump (incrementDreamExperience); the long-lived kernel owns the actual cycle. A new boundary-enforcement test in tests/unit/architecture/hooks-boundary.test.ts fails CI if any hook handler re-introduces heavy work.

  • Three-signal agent routing: static score + Q-value blend + mincut-gated ε-greedy exploration (ADR-095, #488 Phase 4). The Q-table from #487 is now actually consumed during routing decisions. A sigmoid-normalized Q-value blends into per-agent scores with a qWeight that ramps from 0 (no Q-data) to 0.4 (mature). Crypto-random ε-greedy selection diversifies the catalog; an ADR-068-style mincut safety gate dampens exploration 5x when the swarm topology is critical. The AQE_ROUTER_EXPLORATION_RATE=0 env var is the rollback knob.

  • mineExperiences now auto-fires (#486 Gap A). The LearningConsolidationWorker ticks every 30 minutes and now includes a per-domain mineExperiences sweep with a watermark cursor at learning:consolidation-cursor:{domain}. Cursor advances only on successful mining, so failures and empty windows don't silently consume fresh experiences arriving milliseconds later. learning:pattern:* kv fills in default deployments instead of staying empty.

  • Self-learning loop observability (#488 Phase 1 B.2). New aqe learning loop-health CLI subcommand shows liveness of the three loop components (CapturedExperienceBridge, LearningConsolidationWorker, DreamScheduler) with per-component verdicts (live / stale / never-ran) and a routing-diversification dashboard (7-day exploit/explore counts, avg quality per bucket, avg mincut multiplier, avg Q-weight). Operators finally have a one-command view of whether the loop is closing.

  • Daemon pidfile probes globally-installed agentic-qe directly (#488 Phase 1 B.1). The generated .agentic-qe/workers/start-daemon.cjs previously fell back to npx --yes agentic-qe mcp when no local install existed, but child.pid was then the npx wrapper PID (which exits as soon as it forks the real bundle), causing aqe daemon status to misreport liveness. The script now probes require.resolve('agentic-qe/dist/mcp/bundle.js') first to find the global install; if it falls back to npx, a WARNING in daemon.log surfaces the degraded pidfile contract to operators.

  • dream_insights retention sweep (#488 Phase 3 C.2). Stale unapplied insights older than 30 days now get pruned on every worker tick. Applied insights stay forever (audit trail); recently-created insights stay regardless of applied state. The table no longer grows unbounded.

Changed

  • Bridge cursor is now monotonic (#488 Phase 3 C.3). CapturedExperienceBridge.drain reads back the persisted cursor before writing and uses max(this.cursor, persisted) so cross-process races (e.g., duplicate daemons) can't regress the cursor and cause duplicate event re-publication.

  • Hooks no longer trigger dream cycles inline (ADR-094 boundary contract). The checkAndTriggerDream call is removed from post-edit and post-task; JSON output now emits dreamTriggered: false with dreamReason: 'deferred-to-kernel' so operators reading the JSON see where the cycle actually runs rather than a bare false literal. Rollback path is documented in ADR-094.

  • SQLitePatternStore.recordUsage is now a thin wrapper around the new shared recordPatternUsage helper. Throw-on-missing-pattern semantics preserved.

Architecture Decision Records

  • ADR-094: Kernel-Side Dream Cycles + Hooks-as-Producers Boundary. Formalizes the architectural rule that hook subprocesses must not do work exceeding ~100ms. The CapturedExperienceBridge pattern (proven in v3.9.27) is now applied to dream cycles too. Boundary enforced by CI test.

  • ADR-095: ε-Greedy Routing Exploration Policy. Documents the three- signal blend (static + Q-value + mincut-gated ε), the rollback knob, and the post-deploy telemetry surfaces in aqe learning loop-health.

[3.9.30] - 2026-05-14

Patch release fixing six user-reported issues across MCP tooling.

Fixed

  • __dirname is not defined in ESM context (#467). Several tools and init phases were referencing the CommonJS __dirname global from inside ESM modules, which crashed at first use of file-path resolution. Added fileURLToPath(import.meta.url) polyfills in workflow-loader.ts, quality-criteria-service.ts, init/phases/07-hooks.ts, init/phases/10-workers.ts, cli/commands/sync.ts, integrations/n8n/n8n-adapter.ts, and integrations/n8n/agent-factory.ts. qe_requirements_quality-criteria and qe_workflows_browser-load now succeed instead of crashing.

  • qe_embeddings_search returned 0 results, similarity scores near zero (#469). The ONNX embedding generator was using a random-vector mock, so identical text produced different vectors each call and cosine similarity was meaningless. The generator now routes through @xenova/transformers' all-MiniLM-L6-v2 pipeline. Semantic similarity is now correct (e.g. "apple pie" vs "apple fruit pie recipe" ≈ 0.78 cosine, was -0.07). Also fixed threshold || 0.5threshold ?? 0.5 so callers can legitimately pass threshold: 0 to disable the filter.

  • qe_coherence_collapse returned contradictory output: riskLevel: "critical" with isAtRisk: false (#470). When required input fields like health, errorRate, or utilization were missing, the heuristic computation propagated NaN through the score, and categorizeRisk(NaN) fell through to "critical" while NaN >= threshold evaluated to false. Now guards non-finite values, defaults missing numeric fields to safe values, and derives isAtRisk from riskLevel so the two can never disagree.

  • qe_tests_schedule crashed with this.config.phases is not iterable (#472). The MCP wrapper didn't pass an explicit phase list, and the pipeline required one. The pipeline now falls back to DEFAULT_TEST_PHASES (unit → integration → e2e) when callers don't specify, so the tool runs out of the box.

  • session_cache_stats reported 0% hit rate even on identical repeated calls (#473). The session operation cache was implemented correctly but never wired into the MCP tool dispatcher — only TokenOptimizerService was using it. The cache is now consulted for isConcurrencySafe tools (read-only, idempotent), and successful results are stored. Repeated identical calls now hit the cache, producing measurable token savings. Can be disabled via AQE_SESSION_CACHE=off.

  • test_generate_enhanced accepted any language value but always emitted JavaScript/vitest (#474). language: "powershell" produced syntactically-invalid JS saved as .test.ps1. Now validates language against the supported set (typescript, javascript, python, java, csharp, go, rust, swift, kotlin, dart) and rejects unsupported values with a clear error. Auto-derives framework from language instead of always defaulting to vitest. Rejects framework/language mismatches that would produce wrong-language output. The MCP schema enum for framework was expanded to expose all 16 generators we already ship.

[3.9.29] - 2026-05-14

Hotfix for v3.9.28 — bridge payload shape (#484).

Fixed

  • learning.ExperienceCaptured published with the wrong payload shape; handleExperienceCaptured short-circuited on every event and no learning:experience:* keys were written (#484, follow-up to #482 by @Jordi-Izquierdo-DDS, verified on his shop's patch 050). After v3.9.28 fixed the subscriber-loading order, subscribers were reliably present and their handlers fired for every bridge event — but the bridge's flat payload { experienceId, domain, agent, task, success, ... } didn't match the handler's destructure (const { experience } = event.payload). event.payload.experience was undefined, the early-return guard tripped, and recordExperience was never called.

    Fix: the bridge now publishes the canonical nested shape { experience: TaskExperience-shaped, reward } for the universal learning.ExperienceCaptured event, matching the existing publisher (src/learning/experience-capture.ts:1043) and the coordinator's handler signature. Domain-specific fan-out events keep their existing flat basePayload shape (per the issue's explicit guidance — changing it would break out-of-tree subscribers).

Changed

  • Bridge tests now parametrized over multiple domains (per #484 suggestion): the universal-event payload shape is verified across test-execution (has fan-out), requirements-validation, security-compliance, and visual-accessibility (no fan-out — pure universal-event path). The previous single-domain integration test passed only because test-execution's fan-out wrote a kv key via a different handler, masking the broken universal path.

[3.9.28] - 2026-05-14

Hotfix for v3.9.27 — bridge subscriber wiring.

Fixed

  • CapturedExperienceBridge published events to a kernel with zero subscribers (#482). The v3.9.27 bridge correctly drained captured_experiences rows and advanced its cursor, but no learning:experience:* keys appeared and the learning-consolidation worker still saw nothing. Root cause: the kernel default lazyLoading: true meant domain plugins weren't loaded by the time kernel.initialize() started the bridge, so each plugin's subscribeToEvents() had not yet registered handlers on the eventBus. The bridge's immediate drain published into a kernel with no listeners, the cursor advanced past those rows, and they were silently lost.

    Fix: kernel.initialize() now eagerly loads all enabled domain plugins before starting the bridge, ensuring subscribers exist when the first drain runs. CLI commands that don't need event-driven domain reactions opt out with enableExperienceBridge: false to preserve fast startup. Added an end-to-end integration test (real kernel + real plugin + real drain → asserts kv_store contains a learning:experience:* key) so the same regression can't slip through unit tests again.

[3.9.27] - 2026-05-14

Two architectural fixes from downstream investigations against v3.9.26.

Fixed

  • session-start hook could leak unbounded writes to patterns.rvf (#478) — getHooksSystem() bounded ReasoningBank.initialize() with Promise.race against a 10 s timeout. When the timeout won, the losing init promise kept running in the background and continued to append to the RVF pattern store indefinitely (downstream report: 43.8 GB written in 29 minutes, disk filled, SIGKILL required). Threaded an AbortSignal through ReasoningBank.initialize(), loadPretrainedPatterns(), and seedCrossDomainPatterns() — every awaited step now calls signal.throwIfAborted() before doing work, so the timeout actually cancels the bootstrap instead of leaking past it. The hook caller was switched from Promise.race to AbortController + setTimeout. The hybrid backend init still uses race semantics for now (its own signature refactor is separate), but the leaked promise's resulting backend is disposed once it resolves so SQLite handles aren't held open in the background.

  • Hook-driven activity never reached the 13 domain plugins (#479) — the hook subprocess fires events on hookRegistry, the kernel-side domain plugins listen on eventBus, and the two systems were not bridged. In default aqe init --auto deployments (Claude Code hook driven), every domain plugin's subscribeToEvents() listened to events that nothing emitted; learning:pattern:* keys stayed at zero, qe_learning_optimize reported experiencesProcessed: 0, and the learning-consolidation worker logged "No learning patterns found" on every cycle. Added a CapturedExperienceBridge that runs inside QEKernelImpl and drains the shared captured_experiences SQLite table (already populated by hooks and MCP wrapped handlers) into the kernel's eventBus as learning.ExperienceCaptured plus domain-specific events. Cursor-based drain survives kernel restarts and never republishes. Domain plugins now receive hook activity transparently in every kernel-owning process (CLI, MCP server).

Removed

  • Dead v3-qe-bridge.sh script and its config reference — already declared dead in the v3.6.6 release notes; targeted a v3/dist/ path that no longer exists in the flat repo layout, so it silently no-op'd every invocation. Removed .claude/hooks/v3-qe-bridge.sh and the AQE_V3_HOOK_BRIDGE env var in .claude/settings.json.

  • Obsolete planning docsdocs/LEARNING_IMPROVEMENT_PLAN.md and docs/LEARNING_SYSTEMS_ANALYSIS.md were v3-alpha era artifacts that documented the broken bridge as the integration mechanism and referenced paths (v3/src/...) that haven't existed since the dist flatten.

  • Five orphan workers in src/optimization/qe-workers.ts (949 LOC) and their tautological tests (407 LOC). PatternConsolidatorWorker, DreamConsolidatorWorker, CoverageGapScannerWorker, FlakyTestDetectorWorker, RoutingAccuracyMonitorWorker had zero internal callers and no documented use case. Their functionality is fully covered by the live LearningConsolidationWorker (pattern consolidation, dream cycles via runDreamCycle(), confidence decay, cross-domain identification, Phase 7 continuous learning loop) and FlakyDetectorWorker (flaky tests). Re-exports in src/optimization/index.ts cleaned up.

Changed

  • learning-consolidation worker error message now explains the bridge dependency instead of telling operators to "ensure the learning-optimization domain has stored pattern data" — that message predated the bridge fix and gaslighted users on fresh installs.

[3.9.26] - 2026-05-13

Ten learning-pipeline fixes reported by Jordi against v3.9.24. Most are short-circuits in the post-task hook chain that look fine in isolation but break the end-to-end Stream B/D/F learning loop: experiences land tagged as agent='unknown' and task='edit: ', every Q-learning bucket converges on the same key, dream insights are generated but never applied, patterns cross the promotion thresholds but stay short-term forever, and stale sentinels invert the routing-quality metric. Each fix is small but the cumulative effect is that the learning loop now actually converges on real per-agent signal instead of zeros.

Fixed

  • post-edit recorded experiences with task = "edit: " for ~88% of turns (#453) — $TOOL_INPUT_file_path doesn't expand reliably in Claude Code's PostToolUse context, so --file "" arrived empty and every captured experience was tagged with no path. Embeddings were useless and consolidation matched nothing. Now falls back to reading tool_input.file_path from the Claude Code event JSON on stdin (mirrors the existing route-hook stdin path).

  • aqe hooks stats --json always reported zero (#454) — QEReasoningBank.getStats() only read in-memory counters, which reset to zero on every hook subprocess start. Live DBs with 1,900+ routing rows and 270+ learning outcomes all reported as 0. Now falls back to aggregated DB totals when the in-memory counters are zero. Live verify: routingRequests: 1904, avgRoutingConfidence: 0.396, learningOutcomes: 272, patternSuccessRate: 0.75.

  • Patterns never promoted from short-term to long-term (#455) — recordOutcome() runs with a synthetic task:agent:taskId pattern ID that never matches qe_patterns.id, so the promotion check was always skipped. The bridge loop in persistTaskOutcome updates the real pattern IDs but had no inline promotion check. Patterns crossed successful_uses≥3 / success_rate≥0.7 / confidence≥0.6 and stayed pinned at short-term forever. Added a guarded UPDATE inside the bridge loop.

  • Dream cycles wrote insights but never applied them (#456) — hook-fired dreams called engine.dream() and closed the engine without invoking applyInsight(). DreamScheduler.autoApplyInsights() wires this in the daemon path; the hook path had no equivalent. Reporter saw 378 unapplied insights vs. 9 applied. Now iterates result.insights and applies each actionable && confidenceScore ≥ 0.5 after dream() returns.

  • Q-learning router couldn't differentiate per agent (#460) — --agent "$TOOL_RESULT_agent_id" arrived empty (Claude Code doesn't expose that env var in PostToolUse), so every rl_q_values row landed under action_key='unknown'. Now falls back to the pre-task bridge's recommended agent when --agent is empty, while still respecting an explicit user override.

  • Concurrent hooks triggered overlapping dream cycles that died on database is locked (#461) — multiple subprocesses saw the same stale lastDreamTime, all started ~10s cycles, and ~35% failed on the WAL writer (busy_timeout only serializes sequential contention, not simultaneous writers). Added a dream_cycles peek before opening the engine: if a status='running' row exists in the last 60s, bail out with reason='already-running'. Fail-open.

  • patterns.rvf accumulated orphan vectors across upgrades (#462) — upgrade workflows rewrote qe_patterns via INSERT OR REPLACE without calling RvfPatternStore.delete() on the old IDs. Ghost vectors won cosine-similarity matches and routed to non-existent IDs, so getPattern() returned null and writes failed silently. Reporter saw 24 RVF vectors vs. 16 DB rows. initialize() now diffs the RVF idmap against the DB and deletes orphans on every cold start.

  • experience_applications.tokens_saved was hardcoded to 0 (#463) — the learning-ROI column was permanently useless across every post-task invocation. Replaced the literal 0 with Math.round(qualityScore * 100), scaling the existing 6-dim outcome quality (0.335 worst-case to 0.675 best-case) into a non-trivial 34-68 signal until a real per-task token-delta calculation is wired in.

  • High-quality cli-hook experiences blanket-excluded from consolidation (#464) — issue #348 had filtered out agent='cli-hook' rows to keep low-quality Bash telemetry (quality ~0.40) out of the pipeline. But post-edit experiences are also tagged agent='cli-hook' with quality ~0.75 and success_rate ~1.0, and they're the dominant share. The HAVING avg_quality≥0.5 AND success_rate≥0.6 clause already filters by quality — dropping the over-broad agent-name filter so real usage produces patterns again.

  • Stale routing_outcomes sentinels inverted the quality metric (#465) — sessions that terminated without firing Stop (compact, kill, IDE crash) left their sentinels at quality_score=-1 forever, and newer sessions kept pre-empting them in ORDER BY DESC so the LIMIT-1 close never reached them. Reporter saw 122/149 rows stuck at -1, inverting AVG(quality_score) from a real +0.666 to an observed -0.717. post-route now runs a second sweep UPDATE on sentinels older than 5 minutes, tagged with error='stale-sentinel' for filterability.

Closed as duplicates

  • #457 (dup of #454) — getStats DB aggregation fallback
  • #458 (dup of #455) — bridge-loop pattern promotion
  • #459 (dup of #456) — dream insight auto-apply

[3.9.25] - 2026-05-12

Fixes the route sentinel that routing_outcomes never closed. route hooks (UserPromptSubmit) wrote sentinel rows with quality_score=-1, success=0, relying on post-task to fill them in. But post-task only fires on PostToolUse ^(Task|Agent)$, so any direct-work session (Bash/Edit/Read, no sub-agents) left sentinels open indefinitely — Jordi reported 123+ unresolved rows per session. Stream D never converged. This release adds a post-route subcommand wired into the Stop hook (1:1 with UserPromptSubmit/route) that closes route sentinels using a task_json NOT LIKE '%"taskId"%' discriminator, and tightens updateRoutingOutcomeQuality with the inverse discriminator so post-task only ever closes pre-task sentinels.

Added

  • aqe hooks post-route subcommand (#451) — closes the most-recent unresolved route sentinel via a discriminator that isolates route entries (task_json NOT LIKE '%"taskId"%') from pre-task entries. Quality formula is the 6-dim outcome formula collapsed for unknown duration: 0.325 + 0.25·success + 0.10·1.0 = 0.675 on success / 0.425 on failure. Wired into the Stop hook in both init template paths (src/init/phases/07-hooks.ts and src/init/init-wizard-hooks.ts) so new installs and wizard-driven installs both get the closer automatically.

Fixed

  • routing_outcomes sentinels from the route hook accumulated at quality_score=-1 forever in any session that didn't spawn sub-agents (#451) — updateRoutingOutcomeQuality (the only closer prior to this release) gates on PostToolUse ^(Task|Agent)$, which fires on a minority of turns. Sessions doing direct work via Bash/Edit/Read built up dozens to hundreds of unresolved sentinel rows per session, all reading success=0 in any consumer that didn't explicitly filter quality_score < 0. Stream D never converged. Fix: new post-route subcommand wired into the Stop hook closes the matching route sentinel 1:1 with each turn.
  • updateRoutingOutcomeQuality (post-task) could grab a stale route sentinel by accident (#451) — the UPDATE picked the most-recent unresolved sentinel within 30 minutes biased on used_agent, with no discriminator separating route sentinels from pre-task sentinels. With dozens of route sentinels accumulating, post-task could close the wrong one and miscredit duration/success to a row that wasn't actually about a Task() invocation. Fix: added task_json LIKE '%"taskId"%' filter — post-task now only ever closes pre-task sentinels, symmetric with the new post-route filter.

Upgrade Notes

  • No breaking changes. New installs and re-runs of aqe init pick up the Stop-hook post-route wiring automatically. Existing installs continue working but won't close route sentinels until aqe init is re-run.
  • The Stop hook now invokes npx agentic-qe hooks post-route --success true --json in addition to session-end and brain-checkpoint. Timeout is 5000ms and continueOnError: true, so a slow or failed post-route will not block session teardown.
  • Quality scores on existing-but-resolved route sentinels will not be retroactively adjusted. New turns get the correct quality_score on session end.

Thanks to @Jordi-Izquierdo-DDS for the diagnosis, evidence, and patch shape.

[3.9.24] - 2026-05-12

Fixes the post-task self-learning chain — rl_q_values empty forever. The shipped PostToolUse hook command for Task/Agent matchers used --task-id "$TOOL_RESULT_agent_id", but Claude Code does not populate $TOOL_RESULT_agent_id, so the flag arrived empty. An if (options.taskId) gate inside post-task then short-circuited the entire Stream B/D/F learning pipeline: persistTaskOutcome, updateRoutingOutcomeQuality, and updateHookRouterQValue were never called. As a result rl_q_values stayed at zero rows, captured_experiences from cli-hook-post-task were never written, and task-bridge entries accumulated until TTL. The same regression was fixed in v3.9.21 (patch 030) and silently came back in v3.9.23. A regression test now guards the no---task-id path so the gate cannot return a third time.

Fixed

  • rl_q_values always empty — post-task silently skipped the entire learning chain when --task-id was missing (#449) — registerTaskHooks in task-hooks.ts wrapped persistTaskOutcome, updateRoutingOutcomeQuality, and updateHookRouterQValue in if (options.taskId). The shipped PostToolUse hook command for Task/Agent passes --task-id "$TOOL_RESULT_agent_id", but Claude Code does not populate that variable, so the flag arrived empty and the gate failed on every real invocation. The pre-task routing_outcomes sentinel write at line 195 had the same && options.taskId clause and the same dead-code problem. Both gates removed and replaced with a synthetic hook-${Date.now()} fallback for the patternId / experience / sentinel keys. The bridge lookup in persistTaskOutcome already keys by ORDER BY created_at DESC not by taskId, so Stream F's Bellman update still finds the bridge payload it needs. Added tests/unit/cli/commands/task-hooks-no-taskid.test.ts asserting the pipeline fires when --task-id is absent — guards against re-introduction (this exact gate has regressed twice now, in v3.9.21 and v3.9.23). Thanks to @Jordi-Izquierdo-DDS for the diagnosis, evidence, and the patch shape.

Upgrade Notes

  • No breaking changes. After upgrading, aqe hooks post-task will populate rl_q_values and captured_experiences on every invocation regardless of whether the calling hook passes a --task-id. Existing installations should see Q-values begin accumulating on the next Task tool invocation.

[3.9.23] - 2026-05-11

Fixes the routing learning loop — patternCount: 0 forever. On every install shipped between v3.9.5 and v3.9.22, the 19 bootstrap patterns landed in SQLite but never reached the persistent HNSW index (.agentic-qe/patterns.rvf). The file sat at 162 bytes (header only) for the lifetime of the installation, which meant routeTask() returned patternCount: 0 in every hook output and routing confidence couldn't improve from the domain-match baseline. After this fix, patterns.rvf reaches the expected ~30 KB on first init and existing installations are backfilled from SQLite on next startup.

Fixed

  • Bootstrap patterns never reached the RVF HNSW index — patternCount was permanently 0 (#445) — QEReasoningBank.loadPretrainedPatterns seeded patterns via patternStore.create(options) where options carried no .embedding. RvfPatternStore.store() gates adapter.ingest() on pattern.embedding && this.adapter, so all 19 patterns persisted to SQLite but the HNSW file stayed empty. On subsequent startups the method returned early ("Found existing patterns") without writing the HNSW either, so even after the underlying bug was patched, .rvf remained 162 bytes forever. Two-part fix: (1) fresh installs now route through storePattern() which pre-computes the embedding before reaching patternStore.create(), hitting the ingest gate on the happy path; (2) existing installs trigger a one-time backfill — when adapter.status().totalVectors === 0, embeddings are read from qe_pattern_embeddings and batch-ingested via adapter.ingest(). Guarded against re-ingestion (not idempotent) and safe on non-RVF stores via the optional IPatternStore.getAdapter?() interface method. Partial-rejection ingest results now log a warning. Thanks to @Jordi-Izquierdo-DDS for the diagnosis and initial patch.

  • qe_pattern_usage always 0 — ON CONFLICT upsert returned wrong UUID, breaking the learning feedback loop (#447) — Three layers conspired to silently break Stream C of self-learning. (1) SQLitePatternStore.storePattern() returned the UUID passed to INSERT, not the one actually stored — when ON CONFLICT(name, qe_domain, pattern_type) fired, the existing row's UUID was preserved but the function returned the new one. (2) RvfPatternStore.store() discarded the SQLite return value, leaving pattern.id pointing at a UUID that didn't exist in qe_patterns. (3) QEAgentCompletion hook (qe-hooks.ts) auto-created patterns via storePattern() but discarded the result, then recordOutcome() was called with the stale id → "Pattern not found" → silently caught → qe_pattern_usage stayed at 0. Fixed across all three layers: SQLite now SELECTs the actual id after the upsert; RvfPatternStore captures and aligns pattern.id before HNSW ingest; the hook captures storeResult.value.id and feeds it into recordOutcome. Result on a clean install: qe_pattern_usage accumulates rows, usage_count > 0, and success_rate reflects real outcomes. Thanks to @Jordi-Izquierdo-DDS for the diagnosis.

Changed

  • test:unit:fast excludes two chronically flaky test filestests/unit/learning/qe-reasoning-bank.test.ts and tests/unit/learning/aqe-learning-engine.test.ts are now excluded from the fast unit suite. Both intermittently hit [vitest-pool]: Timeout terminating forks worker when the QEReasoningBank/AQELearningEngine module graph exhausts a single fork. v3.9.22 happened to publish cleanly, v3.9.23 didn't. Following the same pattern as tests/unit/mcp/handlers/domain-handlers.test.ts (already excluded from test:ci). Root cause investigation tracked separately.

Upgrade Notes

  • No breaking changes. After upgrading, the next process start will populate .agentic-qe/patterns.rvf with the 19 indexed vectors automatically — no manual action required.
  • Backfill runs once per process per installation (gated on totalVectors === 0), so the overhead is bounded.
  • IPatternStore gains an optional getAdapter?() method. Custom stores that implement the interface continue to work unchanged; only RVF-backed stores need to expose it.
  • The pattern-id realignment in RvfPatternStore.store() and QEAgentCompletion is additive — existing callers see no behavior change unless they were already relying on the (broken) stale id.

[3.9.22] - 2026-05-09

Stops the Exp counter from silently shrinking. The consolidator's safety valve was deleting up to thousands of rows from captured_experiences without an audit trail; in one production database it destroyed ~16K historical experiences and pinned the statusline counter near a 2,000-row ceiling. The valve is now non-destructive: it soft-archives the same rows instead of deleting them, so the statusline formula (consolidated_into IS NULL OR consolidated_into = 'archived') stays monotonic across releases and every firing leaves an entry in experience_consolidation_log. Also fixes a separate gap: CLI-only projects (aqe init with no MCP server ever started) silently lost every hook-fired experience because the captured_experiences schema was only created during MCP startup.

Fixed

  • Safety valve permanently destroyed experiencesExperienceConsolidator.hardDeleteExcess (src/learning/experience-consolidation.ts) issued DELETE FROM captured_experiences whenever a domain exceeded hardThreshold (default 2000). The DELETE was silent (no log entry), so the loss was invisible until users noticed the Exp counter stuck. Replaced with UPDATE captured_experiences SET consolidated_into = 'archived' over the same selection (oldest, lowest-quality, un-applied). Method name and signature kept stable; result.hardDeleted is now permanently 0 for backward compatibility, the count rolls into result.archived. Every firing now writes a safety-valve-archive row to experience_consolidation_log with the count, current size, and threshold so future reductions are auditable.
  • aqe init followed by CLI hooks lost every captured experiencepersistCommandExperience (in src/cli/commands/hooks-handlers/hooks-dream-learning.ts) ran an INSERT against captured_experiences without ensuring the table exists. The schema is created by initializeExperienceCapture(), which previously only ran from MCP server startup (src/mcp/entry.ts). In a freshly-init'd project where the user runs only CLI hooks (no MCP server attached), the first aqe hooks post-edit reported experienceRecorded: true while silently failing to persist. The hook now calls initializeExperienceCapture() before the INSERT — idempotent (internal lock), so it's a one-time bootstrap on the first hook fire.

Added

  • tests/unit/learning/experience-consolidation-safety-valve.test.ts — 7 regression tests guarding the non-destructive invariant: no physical deletion, active count drops to threshold, statusline-formula count stays monotonic, audit log entry written, no-op below threshold, applied (application_count > 0) rows preserved, result.hardDeleted stays at 0.

Upgrade Notes

  • No breaking changes. ConsolidationResult.hardDeleted field remains in the type but is permanently 0; downstream callers that summed it (e.g., LearningConsolidationWorker) keep working unchanged.
  • Existing rows that were physically deleted by the old safety valve cannot be recovered from the codebase fix — restoration requires re-importing from a backup database. Anyone who held a pre-fix backup can restore by inserting the missing rows with consolidated_into = 'archived'.
  • DB size will grow more aggressively per domain — archived rows persist instead of being pruned. The hardThreshold (default 2000) still bounds the active row count for HNSW build performance; only the destruction is removed.

[3.9.21] - 2026-05-08

Three independent fixes that unblock real-world usage: Windows installs no longer fail when Visual Studio C++ Build Tools aren't installed; the RVF pattern store now actually initializes (FsyncFailed 0x0303 is fixed at the root cause, not patched around with a fallback); and the hypergraph queries findUntestedFunctions / findImpactedTests finally return useful results instead of empty answers.

Fixed

  • Windows installs failed mid-npm install when VS Build Tools were absent (#439) — hnswlib-node@^3.0.0 ships no prebuilt binaries and runs node-gyp rebuild on every install; without the C++ toolchain installed the whole agentic-qe install crashed. Moved to optionalDependencies so npm tolerates the compile failure and continues; HnswAdapter already routes around a missing native binary at runtime via the pure-JS ProgressiveHnswBackend. Replaced the top-level static import hnswlib from 'hnswlib-node' in src/integrations/embeddings/index/HNSWIndex.ts with a lazy require so the package itself loads even when the native module is absent. README and the preinstall script document the toolchain requirement and disclose the brute-force degradation mode honestly.
  • RVF pattern store crashed every time the .rvf file already existed (Jordi RUFLO P020) — getSharedRvfAdapter and the pattern-store factory always called RvfDatabase.create(), which throws RVF error 0x0303: FsyncFailed when the target file exists. Earlier init phases legitimately produce patterns.rvf, so every subsequent CLI / MCP boot crashed RVF init and silently fell back to SQLite (hnswStats.nativeAvailable: false). Reproduced and confirmed against both @ruvector/rvf-node@0.1.7 and 0.1.8 — not a version regression. Replaced with a race-tolerant open-or-create ladder (try open → fall back to create → retry open on create-race) plus dim() verification after open so a dimension-mismatched file is detected and the caller degrades rather than corrupting silently.
  • findUntestedFunctions and findImpactedTests always returned empty (Jordi RUFLO P220 follow-up) — both queries filter on type='test' source nodes joined to type='covers' edges, but buildFromIndexResult only ever wrote type='file' nodes and imports / contains edges. Added HypergraphEngine.synthesizeTestCoverage(), called from the coordinator after buildFromIndexResult succeeds, that re-tags test-shaped file nodes (*.test.ts, *.spec.ts, _test.go, etc.) as type='test' and writes covers edges from each test file to the function entities in the source files it imports. End-to-end verified on a fresh project: aqe hg untested correctly excludes covered functions; aqe hg impacted src/calc.ts returns the right test file.

Added

  • Windows install advisory in scripts/preinstall.cjs — fires only on win32, lists the toolchain options (Python 3 + VS 2022 Build Tools, or VS 2026 + npm ≥ 11.6.3), and explains that the JS HNSW fallback degrades to O(N) brute-force when @ruvector/gnn is also unavailable (the default on Windows since no win32 prebuilds ship). Suppress with AQE_SKIP_WINDOWS_NOTICE=true.

Upgrade Notes

  • No breaking changes. engines.node stays at >=18.0.0 and engines.npm at >=8.0.0 (no Node 18 LTS users will hit EBADENGINE).
  • @ruvector/rvf-node stays pinned at ^0.1.7. The version pin is unrelated to the FsyncFailed fix — that bug was in our caller.
  • Existing installs with a working RVF file see no behavioural change. Installs that previously fell back silently to SQLite will now use RVF — surfacing any latent RVF bugs (lock contention, recall divergence) that were previously hidden. If you observe RVF-specific issues post-upgrade, file an issue; an AQE_DISABLE_RVF escape hatch is on the follow-up list.

[3.9.20] - 2026-05-08

Second wave of self-learning wire-gap fixes built on 3.9.19. HNSW A (the long-term pattern catalog) is now consulted on every task_orchestrate call, hook-side experience writes get embeddings inline instead of waiting for the next-boot backfill, dream cycles inherit the same patient SQLite timeout the rest of the system uses, pattern quality_score actually moves when patterns are reused through the hook flow, and the legacy TrajectoryBridge no longer maintains its own .agentic-qe/trajectories.db outside the unified-memory rule.

Fixed

  • ReasoningBank singleton was lazy-initialized at request time — first task_orchestrate after a cold MCP start paid the full HNSW build cost on the request path; racing calls fell through to context-only matches. Fire-and-forget pre-warm in src/mcp/entry.ts after CrossPhaseHooks eager-init now runs the warm-up in parallel with the rest of MCP startup.
  • aqe_health reported vectorCount: 0 even when the vectors table had hundreds of rowscore-handlers.ts:597 probed getVectorCount on the unified memory manager but the method is vectorCount() (unified-memory.ts:755); the typeof check failed silently. Renamed at both call sites.
  • HNSW A (qe_patterns) was never consulted on the routing decision pathhandleTaskOrchestrate already called getExperienceGuidance() (HNSW C) but the catalog of consolidated long-term patterns was only checked through unrelated MCP tools, never on the request that picked an executor. searchPatterns(task, {limit: 5, domain}) now runs in parallel with getExperienceGuidance() and the top hits are forwarded as patternHints on both the submitTask payload and the workflow executeWorkflow payload.
  • Hook-side captured_experiences writers wrote rows with no embeddingpersistCommandExperience and persistTaskOutcome ran the SQL insert and returned without computing an embedding. ~85% of new captured-experience writes since v3.9.19 came through these two hook paths and contributed zero embeddings, leaving HNSW C cold for hook-driven workloads. Both writers now fire a no-await IIFE after the insert that imports computeRealEmbedding, computes text = ${domain}: ${task}.slice(0, 512), and UPDATEs the row in place.
  • ExperienceReplay.initialize() left ghost rows in HNSW C — the load loop only added rows that already had embeddings; nothing backfilled the rows hook paths left empty (~63% of the table in one observed pulse). Cap-200 fire-and-forget IIFE in initialize() selects ghost rows, computes embeddings via the same real-embeddings config the canonical writer uses, UPDATEs in place, and adds the new vectors to the live HNSW index so they're searchable without restart.
  • qe_trajectories had no embeddings at allTrajectoryTracker.endTrajectory() writes the row with embedding = NULL and there's no follow-up worker; observed 719 hook-created rows with 0 embeddings. Second cap-200 fire-and-forget IIFE in ExperienceReplay.initialize() adjacent to the captured-experiences backfill, scoped to qe_trajectories. PRAGMA-checks the embedding column first (TrajectoryTracker may not have run its schema migration yet on a fresh install).
  • DreamEngine opened a fresh DB handle that never inherited the busy_timeout pragmacheckAndTriggerDream() dynamically imports createDreamEngine, which goes through getUnifiedPersistence().getDatabase(). The hook-side and worker-side busy_timeout pragmas (patches 260/270) never reached that dynamically-imported path. Under concurrent MCP-worker contention on the WAL write-lock, SQLITE_BUSY hit immediately and cycles were marked failed (199/279, 71%, in one session). Applies pragma('busy_timeout = 60000') in DreamEngine.initialize() so dream cycles wait patiently like the rest of ADR-001 Option C.
  • SQLitePatternStore.recordUsage() was unreachable from the hook flow — the canonical updater of qe_patterns.{usage_count, successful_uses, success_rate, quality_score} is only invoked through the HandleTaskOutcomeRecord MCP path. The hook flow that fans out per-pattern experience_applications rows never called it — quality_score stayed pinned at ~0.30, with 88/89 patterns never crossing into long-term. Inline SQL inside the persistTaskOutcome bridge loop after the per-pattern insert mirrors the recordUsage() formula: confidence * 0.3 + min(usage_count/100, 1) * 0.2 + success_rate * 0.5.
  • TrajectoryBridge kept its own .agentic-qe/trajectories.db outside unified memorysrc/adapters/claude-flow/trajectory-bridge.ts:184 opened a separate SQLite file with its own trajectories schema, violating the project's "all data goes through SQLite (better-sqlite3) — one DB, one schema" rule. Feedback written via TrajectoryBridge.endTrajectory() never showed up in any of the queries that read qe_trajectories. persistTrajectory() now opens the unified memory DB via getUnifiedMemory(), maps the bridge's columns onto qe_trajectories (epoch ms → ISO datetime), and writes to the same row everyone else reads.
  • Claude provider implementations ignored ANTHROPIC_BASE_URL — both src/coordination/consensus/providers/claude-provider.ts:181 and src/shared/llm/providers/claude.ts:383 hardcoded the api.anthropic.com fallback when no baseUrl was passed in config, so AQE LLM calls bypassed proxies (Claude Max Proxy, LiteLLM) that the rest of the codebase honors via process.env.ANTHROPIC_BASE_URL. Both providers now consult the env var before falling through to the literal hostname.

Added

  • Opt-in trajectory judge — new src/mcp/handlers/trajectory-judge.ts runs at the end of handleTaskOrchestrate (fire-and-forget) when AQE_TRAJECTORY_JUDGE=1 and ANTHROPIC_API_KEY are both set. Picks the 5 most-recent qe_trajectories rows where feedback IS NULL AND ended_at IS NOT NULL, asks Claude Haiku for a structured {quality, reasoning, improvement?} verdict, and writes the JSON into qe_trajectories.feedback. Quality is embedded in the JSON to avoid a schema migration. Bounded to 5 rows per call. Uses the proxy-aware base URL from the same release.

Upgrade Notes

  • No breaking changes for users on npx agentic-qe.
  • Pre-existing installs with .agentic-qe/trajectories.db will see that file go stale — the live writer now targets memory.db. aqe init reset --all still cleans up the legacy file.
  • AQE_TRAJECTORY_JUDGE=1 is opt-in by design: each task_orchestrate call triggers up to one Claude Haiku request when there are unjudged trajectories. Cost is bounded to 5 × 200-token Haiku calls per task_orchestrate in the worst case.
  • The HNSW A pattern hints introduce a single additional searchPatterns call per task_orchestrate. Fail-soft on errors so a misbehaving HNSW A path can't block task execution.

[3.9.19] - 2026-05-05

Self-learning loop wire-gap fixes. The system shipped agents that observed and learned, but several wire-gaps between subsystems caused the learning signal to drop before it completed the loop: workers registered without ticking, HNSW indexes loaded empty, hook outputs disappeared into ungated paths, and quality scores were two-valued instead of multi-dimensional. This release closes those gaps end-to-end so routing → capture → consolidate → embed → route-better actually completes.

Fixed

  • Background workers registered but never tickedsrc/mcp/entry.ts:211 overrode getDaemon({ autoStart: false }), neutering workerManager.startAll(). The "[MCP] Background workers started (11 workers)" log read total registered workers, not scheduled ones, so dream cycles, pattern promotion, and learning consolidation never ran on schedule. Now uses the canonical default (DEFAULT_CONFIG.autoStart = true per workers/daemon.ts:53); see ADR-001 "AQE workers WAL contention strategy".
  • HNSW vector index loaded empty under our default unified-bridge pathPatternStore.initializeHNSWInternal() had the embedding-load loop only in the legacy fallback branch. With useUnifiedHnsw: true (our default per ADR-071), the function returned at the unified-bridge branch before the load loop ran, so existing qe_pattern_embeddings rows never populated the index and routing fell back to context-only matches. Extracted loadEmbeddingsIntoHNSW() and call it from both the unified and legacy paths.
  • aqe hooks stats --json reported vectorCount: 0 even after embeddings loadedgetStats() deliberately skipped lazy HNSW init, so the reported state was the pre-init zero state instead of actual content. Now awaits ensureHNSW() before reading. Cost is bounded by the existing 5s init timeout.
  • Pattern writers produced "ghost" patterns with no embeddings — three live writers wrote to qe_patterns (canonical SQLitePatternStore.storePattern, dream-learning consolidation, and the learning-consolidation worker) but only the canonical writer paired the row with a qe_pattern_embeddings row. The two bypass paths produced rows that loaded into in-memory cache but stayed invisible to HNSW pattern recall. Added ensurePatternEmbedding() helper in src/learning/embed-and-insert-pattern.ts and routed both bypass writers through it so all three speak the same embedding-config "lingua franca" (per ADR-058 locality).
  • ^Task$ matcher in shipped aqe init hook templates didn't fire on real Agent dispatch — Claude Code now dispatches subagent tools as both Task (legacy) and Agent (current). Pre/post-task hooks never fired on Agent dispatch, leaving zero deltas in captured_experiences / experience_applications / qe_trajectories for real subagent invocations. Updated src/init/phases/07-hooks.ts (the template that ships via aqe init) and project .claude/settings.json to ^(Task|Agent)$.
  • Routing-collapse onto one agent had no observability signalQETaskRouter.route() returns confidence values as low as 0.27 with no flag distinguishing low-confidence routes from high-confidence ones in logs or routing_outcomes. Added lowConfidence: confidence < 0.5 to the pre-task JSON output, embedded in decision_json, and surfaced as error='low-confidence' in routing_outcomes so collapse is queryable.
  • captured_experiences flooded with non-test Bash command noisepersistCommandExperience was called unconditionally for every Bash command, so git status, ls, md5sum, etc. all wrote rows at low success rates that diluted pattern signal. Now gated to test/build/lint commands; reasoningBank.recordOutcome (the broader metric path) stays unconditional.
  • task-executor.ts recorded only two distinct quality scoresqualityScore: success ? 0.8 : 0.2 defeated the point of treating quality_score as a learnable signal. Replaced with the same 6-dim formula the post-task hook UPDATE path uses (0.25 * success + 0.325 baseline + 0.10 * duration_tier), yielding 6+ distinct quality bands per success/fail × duration combination.
  • Knowledge-graph findUntestedFunctions / findImpactedTests / findCoverageGaps returned empty regardless of indexing activityHypergraphEngine.buildFromIndexResult only persisted import edges; the file→entity contains edges that those queries depend on were never written. Phase 2 now writes a contains edge per file→entity. Phase 3 also resolves relative import specifiers (./foo, ../bar) against the source file's directory and probes common TS/JS/Python extensions plus /index.ext for directory imports — previously bare-module imports were the only ones that could match a hypergraph_nodes row.
  • Hook subprocesses failed under WAL contention with default 5s busy_timeout — added applyHookBusyTimeout(db) helper that sets PRAGMA busy_timeout = 60000 on hook DB connections so they wait patiently through worker bursts. Workers in MCP keep the platform default (5s) so they fail fast and retry on the next tick, yielding the lock to hooks under contention (ADR-001 Option C asymmetric prioritization). Wired at all 8 hook handler db-open sites.
  • CrossPhaseHooks executor was lazy-initialized but never actually called initialize() at MCP start — under sustained queen-event-handlers traffic, kv_store / qcsd-memory rows did not grow because the executor's config was never parsed. Now eagerly initializes after [MCP] Ready so hook events fire through a fully-initialized executor from the first request.
  • Statusline reported 0 ADRs even when ADRs existedADR_DIR pointed at implementation/adrs but the actual location is docs/implementation/adrs. Both the bash statusline and its CJS helper looked in the wrong place; corrected to the right path.

Added

  • Full pre-task JSON enrichment — pre-task output now includes selectedPatternIds (top-5 UUIDs from routing.patterns), historicalBest (best agent + average quality + sample count from past success=1 routes), priorVerdicts (last 7 days from kv_store namespace verdicts), estimatedTokenSavings (sum across selected patterns), lowConfidence flag, and bridgeKey. Downstream tooling can read these without re-querying.
  • persistTaskOutcome helper — single transaction-wrapped function that writes captured_experiences (source cli-hook-post-task), experience_applications (base + 1 per pattern_id from bridge with tokens_saved distribution), single-step qe_trajectories, multi-step trajectory stitching from siblings sharing the same task ID in the last hour, and increments dream_insights.applied for top-3 actionable rows on success. Returns derived fields the q-learning integration consumes.
  • updateHookRouterQValue Bellman update — proper column semantics per ADR-061/087: algorithm='q-learning', agent_id='aqe-hook-router' (per-instance partition; coexists with canonical RuVectorQLearningRouter agent_id 'q-router' via ON CONFLICT partition), structural state_key='${taskType}|${priority}|${domain}|${complexityBucket}' (verbatim from q-learning-router.ts:591), Q ← Q + α(r + γ·max_a' Q(s',a') Q) with α=0.1, γ=0.9, asymmetric reward (+0.1 / 1.0).
  • updateRoutingOutcomeQuality post-task UPDATE — applies the 6-dim quality formula to the most-recent routing_outcomes sentinel row (quality_score = -1) written by pre-task. Prefers rows matching the actual used_agent. Closes the routing-quality split-write loop.
  • test_outcomes and coverage_sessions writers in post-command hook — when a recognized test framework runs (jest/vitest/pytest/mocha), inserts a test_outcomes row capturing framework, language, pass/fail, and execution time. When coverage/coverage-summary.json is present (Istanbul format), parses and inserts a coverage_sessions row with after_lines/branches/functions, reusing the prior session's after_* values as before_* so coverage delta is calculable.
  • Task-bridge with TTL — pre-task writes a kv_store namespace task-bridge entry (10-min TTL) carrying selectedPatternIds, structural state derivation (taskType/priority/domain/complexityBucket), and estimatedTokenSavings for post-task to consume. One-shot consumption (post-task DELETEs after read).

Changed

  • quality_score in routing_outcomes now means "outcome quality after task ran", not routing confidence. Routing-confidence stays in decision_json where it semantically belongs. Both writers (pre-task in task-hooks.ts and aqe hooks route in routing-hooks.ts) write a sentinel quality_score = -1 that post-task UPDATEs with the 6-dim formula.
  • EdgeType schema extended with 'contains' for the new file→entity edges.
  • HybridMemoryBackend busy_timeout in hook subprocesses bumped from 5000 to 60000 ms per ADR-001 Option C.

[3.9.18] - 2026-04-30

Four MCP fixes shipped together: governance no longer blocks legitimate tool calls, generated jest tests now actually run, and coverage error messages tell you what really happened. Also adds the agentic-qe-fleet Claude Code plugin (11 agents, 9 commands, 9 skills) for one-command install via /plugin marketplace.

Fixed

  • coverage_analyze_sublinear and other domain MCP tools blocked by governance after 12 callscontinue-gate-integration.ts was passing a synthetic history.length * 500 token estimate to the guidance gate. The linear-regression slope detector saw slope = 500, threshold = 0.02, and emitted a throttle decision. The integration then mapped throttle to shouldContinue: false, surfacing as Task blocked by governance: Budget acceleration detected (slope: 500.0000 > 0.02) on legitimate first-time tool invocations. Root-cause fix: replaced the synthetic estimate with totalTokensUsed: 0 and budgetRemaining.tokens: MAX_SAFE_INTEGER until real token telemetry is wired in. The coherence/uncertainty/rework checks still operate on real signals. mapGuidanceDecision was also corrected so throttle is treated as a soft slowdown hint (proceed with throttleMs), and only pause/stop block.
  • test_generate_enhanced with framework: "jest" produced tests that crashed at runtime — the generator emitted import { describe, it, expect, beforeEach } from 'jest';, but the 'jest' package is the CLI, not a runtime export. Tests-as-emitted failed with Cannot find module 'jest'. Fix: emit from '@jest/globals' for jest (modern jest 28+ runtime API) and from 'vitest' for vitest. Both the main analysis path and the stub fallback now produce framework-correct imports.
  • Generated test imports referenced /tmp/aqe-temp-* paths that never existed in the user's codebase — when callers passed sourceCode without filePath, the handler wrote a temp file for analysis and the generator baked that throwaway path into emitted test imports. Fix: added IGenerateTestsRequest.importPathOverrides so the handler can tell the generator the logical import path (the user-supplied filePath when available, or './module-under-test' placeholder + TODO comment when not). The temp file is also explicitly cleaned up via fs.unlink after generation.
  • qe/coverage/gaps error message misled callers about which input failed — when an explicit coverageFile parsed to zero entries, the tool returned "No coverage data found in '<target>'" (templated with target, not coverageFile). Callers reasonably assumed the coverageFile parameter was being silently dropped. Fix: distinguish the two miss paths — empty coverageFile returns "Coverage file '<path>' contains no usable coverage data..."; autodiscovery miss returns "No coverage data found by autodiscovery under target '<target>'...".

Added

  • test_generate_enhanced MCP schema now exposes framework, filePath, coverageGoal, aiEnhancement, and detectAntiPatterns parameters — previously only sourceCode, language, and testType were declared, so framework: jest and other args were silently dropped at the schema validation layer even though the underlying handler accepted them.
  • agentic-qe-fleet Claude Code plugin — a slim starter bundle of the AQE platform installable via /plugin marketplace add ruvnet/agentic-qe. Includes 11 specialized QE agents (model-routed: 6 on Opus for heavy reasoning, 5 on Sonnet for focused execution), 9 trust-tier-2/3 skills with scoped allowed-tools lists, 9 /aqe-* slash commands, and an auto-registered MCP server entry. Tier-1 (untested) skills are excluded from the bundle per AQE trust-tier policy.
  • scripts/smoke-test-fixes.sh — end-to-end MCP smoke test covering all four fixes with proper exit-code handling (single sys.exit, no false negatives).
  • scripts/plugin-load-test.sh — 14-check structural validation for the bundled plugin.

Changed

  • IGenerateTestsRequest interface gains importPathOverrides?: Record<string, string> — public API extension. Existing callers continue to work; the field is opt-in and only consulted when present.

[3.9.17] - 2026-04-27

One-line fix that closes the routing learning loop. The shipped aqe init template wired the UserPromptSubmit hook to --task "$PROMPT", but Claude Code never exposed $PROMPT as an env var — every prompt routed as empty. The CLI now reads stdin event JSON, the templates drop the broken arg, and existing projects upgrade automatically on re-init.

Fixed

  • aqe init UserPromptSubmit hook silently routed every prompt as empty — the generated .claude/settings.json template invoked npx agentic-qe hooks route --task "$PROMPT" --json, but Claude Code (≥2.1) does not export $PROMPT as an env var for UserPromptSubmit hooks; the prompt body only arrives via stdin event JSON. The shell expanded "$PROMPT" to "", so aqe hooks route always saw an empty task, the reasoningBank returned the same default agent on every prompt, and routing_outcomes.task_json was persisted as {"description":""} for every entry — closing the routing learning loop. Fix: aqe hooks route now reads stdin JSON events as a fallback and extracts event.prompt / event.user_prompt / event.command / event.tool_input.{prompt,description}; the templates in src/init/phases/07-hooks.ts and src/init/init-wizard-hooks.ts drop the broken --task "$PROMPT" argument so stdin delivery works. Re-running aqe init on existing projects detects the broken old hook (smart-merge isAqeHookEntry) and replaces it with the fixed one. Manual --task <description> usage is preserved for backward compatibility.

Upgrade Notes

  • Existing projects: re-run npx agentic-qe init --upgrade. Verify with jq '.hooks.UserPromptSubmit' .claude/settings.json — the hook should read npx agentic-qe hooks route --json (no --task "$PROMPT"). After a few prompts, confirm sqlite3 .agentic-qe/memory.db "SELECT task_json FROM routing_outcomes ORDER BY rowid DESC LIMIT 5" shows real prompt content instead of {"description":""}.

[3.9.16] - 2026-04-24

Brain-export tooling + native-binding advisor. Three new CLI commands that make the QE brain snapshot easier to inspect and make optional native deps visible. Closes the last actionable items on issue #332 (brain export improvements) and item 2 of issue #383 (upgrade advisor).

Added

  • aqe brain diff <a> <b> — Compare two brain exports. Always compares manifests (version, checksum, per-table record counts, domain list delta) across any mix of JSONL and .rvf files. When both sides are JSONL it also reports record-level added / removed / changed IDs per table — identity comes from the primary key on keyed tables and from dedup columns on append-only tables (witness_chain, qe_pattern_usage). Flags: --table <name>, --verbose, --json. Exit 0 when identical, 1 on any difference.
  • aqe brain search -i <export> — Offline filtered search over a JSONL brain export. Defaults to qe_patterns; --table <name> targets any of the 25 tables. Filters: --domain (repeatable, combines with AND), --pattern-type, --since/--until (ISO dates against updated_atcreated_attimestamp), -q/--query (case-insensitive substring over name + description), -l/--limit (default 20), --json.
  • aqe upgrade — Read-only advisor that detects which optional native bindings load on this platform (@ruvector/rvf-node, @ruvector/solver-node, @ruvector/attention, @ruvector/gnn, hnswlib-node), shows the current useRVFPatternStore / useSublinearSolver / useNativeHNSW / useGraphMAEEmbeddings / useQEFlashAttention flag state after RUVECTOR_* env overrides, and prints install hints for anything missing. Does not mutate feature flags, env, or config. Flags: --json, --strict (exits 1 when an optional is missing). Exit 2 when a required native fails to load.
  • Shell completions for brain and upgrade — bash/zsh/fish/PowerShell tab-completion scripts now cover both new commands and all six brain subcommands (export, import, info, diff, search, witness-backfill). For brain search --domain, bash completion sources the canonical AQE domain list.

Fixed

  • Stale issue-tracker drift — Issue #355 ("RuVector Integration: Remaining Work Tracker") and issue #332 ("Brain Export LOW-priority improvements") had diverged from reality. Delivered items from #355 (RVF export/import CLI, manifest-with-checksums, witness-integrity validation) were still shown as TODO. Consolidated the overlap with #383 into a single comment on #355, split long-horizon RuVector work into the new #432 backlog issue, and closed #355 + #332 with explicit delivered / won't-fix rationale for each remaining item.

Changed

  • 22 pre-existing no-useless-escape lint errors in src/cli/completions/index.ts cleaned up during the completions work (\$foo$foo inside the JS template literal for the generated bash script; \${files[@]} preserved because ${ triggers template interpolation). Generator output is byte-identical after the cleanup, verified via bash -n.

Upgrade Notes

  • No breaking changes. Three new CLI commands; existing commands unchanged.
  • aqe upgrade is the recommended first-run diagnostic for users reporting "HNSW is slow" or "why is my router doing power iteration" — it tells them which native deps are missing and exactly what to npm install.
  • If you've built tooling that parses aqe brain's help output, note that two new subcommands (diff, search) are now listed.

[3.9.15] - 2026-04-22

qe-browser skill promoted to Implemented (ADR-091). Closes the final gaps from the v3.9.9 introduction: the skill's eval file is now a runnable evaluation via a new aqe eval run --skill qe-browser command, a CI workflow gates changes with both unit and smoke tests, a getting-started guide walks new users through install and the five primitives, and Linux ARM64 users get a copy-paste VIBIUM_BROWSER_PATH hint after aqe init --auto detects their system chromium. Trust tier 3.

Added

  • aqe eval run --skill <skill> CLI — New command that executes a skill's evals/<skill>.yaml file as real CommandRunner evaluations (not mocks). Uploads JSON results for post-run inspection. Lets any skill author turn their eval YAML into a reproducible CI gate. First consumer: qe-browser.
  • Linux ARM64 platform detection in aqe init --auto — After installing Vibium, the installer now probes os.platform + os.arch on Linux aarch64 and scans a prioritized list of system chromium locations (/usr/bin/chromium, chromium-browser, google-chrome, google-chrome-stable, /snap/bin/chromium). When a browser is found, it prints an exact export VIBIUM_BROWSER_PATH=... line the user can copy. When none exists, it surfaces the apt-get install chromium remediation. No more silent hangs on ARM64 hosts with no matching browser.
  • docs/guides/qe-browser-getting-started.md — Install, smoke check, eval run, and example CLI invocations for all five primitives (vibium assert, vibium batch, check-injection, visual-diff, vibium run-intent). This is the doc to send new users to.
  • .github/workflows/test-qe-browser.yml — Three-job CI gate that fires on PRs touching the skill, its installer, or CommandEvalRunner. Job 1 runs the full vitest sweep. Job 2 installs pinned Vibium (^26.3.18) and runs smoke-test.sh against real httpbin fixtures — the contract gate for the five primitives. Job 3 runs aqe eval run --skill qe-browser against real Vibium and uploads the eval JSON as a CI artifact. Workflow validated with actionlint 1.7.1.

Fixed

  • qe-browser eval YAML no longer requires a local fixture server — Two test cases (tc006, tc007) were pointing at http://localhost:8088/qe-browser/SKILL.md.html, which required an unstarted fixture server, so running aqe eval run --skill qe-browser on a fresh machine would have failed. Rewrote both to use https://httpbin.org/html (matching scripts/smoke-test.sh). tc009 (poisoned-page check-injection) was dropped from the yaml with an explicit GAP comment — its local fixture is out of scope for CommandEvalRunner, and the severity logic it exercises is already unit-tested at tests/unit/scripts/qe-browser-check-injection.test.ts. yaml test_cases now reflects the runnable set (10 vs 11).
  • Deterministic viewport in CI — yaml tc006 / tc007 now include vibium --headless viewport 1280 720 setup steps so their output matches smoke-test.sh byte-for-byte. No more "passes locally, fails in CI" from default-viewport differences.
  • Correct Vibium pin comment — Previous changelog claimed ^26.3.18 was a "major.minor-line pin". Under npm semver, ^26.3.18 accepts 26.99.x, so the comment was factually wrong. Rewritten in the skill to accurately describe the intent: major-line pin that blocks 27.0+ while allowing auto-uptake of 26.x patches and additive features, with scripts/smoke-test.sh as the belt-and-suspenders API contract gate. The spec itself stays ^26.3.18.

Changed

  • ADR-091 status: Implemented (trust_tier 3) — All gaps from the v3.9.9 introduction are closed: runnable eval, CI workflow, platform detection, documentation, and yaml/smoke unification. Dependent browser-using skills (accessibility-testing, pentest-validation, enterprise-integration-testing) now reference qe-browser as the canonical runner, with Playwright kept as a documented fallback where BiDi coverage is insufficient (Firefox/Safari in compatibility-testing, the visual-testing-advanced legacy section).

Upgrade Notes

  • aqe init --auto on Linux ARM64 hosts (e.g., Raspberry Pi, Apple Silicon Docker, AWS Graviton) now surfaces a VIBIUM_BROWSER_PATH export hint after Vibium install — copy the printed line into your shell before running vibium commands.
  • Skill authors can now ship an evals/<skill>.yaml file and run it with aqe eval run --skill <skill>. See .claude/skills/qe-browser/evals/qe-browser.yaml for a real example.
  • No breaking changes. CLI surface additions only.

[3.9.14] - 2026-04-20

Security + supply-chain hardening. Closes five P0 release blockers from the v3.9.13 QE audit: 15 critical runtime npm vulnerabilities, 79% tarball bloat, hardcoded retiring model IDs at tier 1, a broken lint harness, and a loose MCP contract. Tarball shipped size drops from 19.9 MB to 9.6 MB (-52%). Also tightens six MCP tool contracts, patches a command-injection path in aqe learning repair, and stops the telemetry workflow from push-forcing to protected main.

Fixed

  • 15 critical runtime vulnerabilities eliminated — The @xenova/transformers → @claude-flow/{browser,guidance,embeddings} → onnxruntime-web → onnx-proto → protobufjs chain pulled in protobufjs <7.5.5 (GHSA-xq3m-2v4x-88gg, CWE-94 arbitrary code execution). Pinned to ^7.5.5 via both overrides and resolutions. npm audit --omit=dev now reports zero critical/high issues.
  • Command injection in aqe learning repair — The --file path was shell-interpolated into three execSync calls. A crafted path could break out of shell quoting and execute arbitrary commands. Rewrote to execFileSync with explicit file-descriptor redirection and stdin streaming — no shell parsing of user input at all.
  • advisor_consult MCP contract — The ADR-092 advisor tool accepted empty/whitespace agent and task values and silently shelled out to aqe llm advise with placeholders. Now rejects missing or blank inputs before any child process spawn.
  • Tier-1 model tier was hardcoded to a retiring model ID — Six call sites (central constants plus five domain services: test-execution, contract-testing, chaos-resilience, learning-optimization, visual-accessibility) resolved tier 1 to claude-3-haiku-20240307, which will 404 after Haiku 3 retirement. Routed through claude-haiku-4-5 (ADR-093).
  • npm run lint was broken — The script invoked eslint on both src and tests, but .eslintrc.cjs explicitly ignores tests/. ESLint aborted instead of linting anything. Narrowed the script to eslint src --ext .ts so the harness runs.
  • qcsd-production-trigger.yml no longer pushes to protected main — The post-publish telemetry job ran git push directly to main, which failed 8/10 times because of branch protection. Now pushes to a bot branch and opens a PR for maintainer review. Artifact upload continues to preserve the raw payload for 90 days regardless of PR merge.

Changed

  • Tarball is 52% smallerdist/cli/chunks/ accumulated stale code-split chunks across rebuilds (799 shipped, only 240 fresh). Build script now cleans the chunks directory before each build. Combined with lazy-loading @faker-js/faker (see below), shipped size drops from 19.9 MB → 9.6 MB and unpacked from 88.5 MB → 48.2 MB.
  • @faker-js/faker is no longer bundledtest-data-generator.ts previously static-imported faker at the module top, pulling the devDep into every shipped artefact. Now lazily loads via dynamic import() on first use. Faker is an optional runtime dep — users who invoke test-data generation must install it themselves (with a clear error message pointing them to npm install --save-dev @faker-js/faker).
  • @claude-flow/guidance demoted to optionalDependencies — Usage is already guarded by try/await import/catch fallback paths, and no newer stable version exists on npm. Keeping it installable for users who want it without forcing it on users who don't. See docs/qe-reports-3-9-13/research-claude-flow-guidance-strategy.md.
  • Six MCP tools now mark their load-bearing params as requiredagent_metrics(agentId), coverage_analyze_sublinear(target), accessibility_test(url), defect_predict(target), code_index(target), and advisor_consult(agent, task). Clients that omit these parameters get a clear rejection instead of the tool running with empty placeholders.

Added

  • v3.9.13 full-quality audit — Twelve reports from an 11-agent QE swarm analysing code complexity, security, performance, test quality, SFDIPOT product factors, dependency health, API contracts, DDD architecture, accessibility, brutal honesty, and CI pipelines. Published at docs/qe-reports-3-9-13/ alongside two follow-up research memos on the guidance strategy and agent-count recount.

[3.9.13] - 2026-04-17

Migrate the fleet to Claude Opus 4.7 / Sonnet 4.6 / Haiku 4.5 ahead of the June 15 Sonnet 4 retirement. xhigh becomes the fleet-wide default effort level for better agentic-coding quality, and security agents stay pinned to Sonnet 4.6 until the Cyber Verification Program application clears. (ADR-093)

Added

  • Opus 4.7, Sonnet 4.6, and Haiku 4.5 in the model registry — New Anthropic models are first-class, with capability flags for adaptive thinking, xhigh effort, tokenizer version, and 1M context. Opus 4.7 is the default ADR-092 advisor model.
  • xhigh effort level, fleet-wide — Every qe-* agent now runs at xhigh by default (Anthropic's recommended starting point for agentic coding). Override per-agent via frontmatter, per-run via QE_EFFORT_LEVEL, or globally via config/fleet-defaults.yaml. Priority chain: env > YAML > frontmatter.
  • Cyber Verification Program application draft — Prepared at docs/security/cyber-verification-application.md for the four cyber-sensitive agents (qe-pentest-validator, qe-security-scanner, qe-security-auditor, qe-security-reviewer), which remain pinned to Sonnet 4.6 until enrollment clears.

Changed

  • Default model constant replaces hardcoded IDs — 25+ hardcoded claude-sonnet-4-20250514 references across routing, providers, cost-tracker, and CLI code now flow through a central DEFAULT_SONNET_MODEL constant in model-registry.ts. Tier 2 and Tier 3 both route to Sonnet 4.6; Opus 4.7 is reserved as an opt-in escalation target via MultiModelExecutor.
  • Post-audit sweep of lingering model references — CI workflow, consensus provider, MCP sampling handler, 12 skill evals, 9 test files, opencode plugin, scripts, .kiro config, and command docs all updated to the new model IDs.
  • ADR-092 advisor default model upgraded to Opus 4.7 — The vendor-agnostic advisor now targets Opus 4.7 by default for escalation paths.

Fixed

  • No fleet breakage at 2026-06-15 Sonnet 4 retirement — A single-commit model sweep removes every live routing reference to the retiring claude-sonnet-4-20250514 ID. Remaining references are intentional compatibility metadata (deprecation dates, Bedrock mappings, historical cost entries).
  • User-facing model listings stay in syncDEFAULT_MODEL_MAPPINGS and related surface areas now reflect the new model lineup so downstream consumers don't see stale IDs.

[3.9.12] - 2026-04-16

Fixed

  • aqe init no longer duplicates hooks when run after ruflo init — The hook merge logic now recognizes ruflo-installed hooks (using dist/cli/bundle.js commands) and replaces them cleanly instead of appending duplicates. User-defined custom hooks are preserved.
  • Claude Flow detection checks root .mcp.json — Detection now looks in the root .mcp.json (where ruflo and aqe actually write MCP config) first, avoiding a 5-10 second fallback to npx --no-install binary probing.
  • Init no longer hangs on Claude Flow pretrain — Removed the redundant runPretrainAnalysis call (120-second timeout) from aqe init. Pretrain is already handled by ruflo init, so this was duplicate work that could stall the init process.

[3.9.11] - 2026-04-13

Fixed

  • aqe init --auto now correctly updates agents and helpers on upgrade — When upgrading from a previous version, init --auto silently skipped updated agent definitions and new helper files if .agentic-qe/config.yaml was missing or incomplete from the prior install. The version detection now falls back to checking for existing agent files, so upgrades work reliably even when the previous init was interrupted before writing config.
  • Visible errors when helper/template sources are missing — The agents installer now logs to stderr when it cannot find the helpers or templates source directory, instead of silently skipping the copy.

[3.9.10] - 2026-04-13

Use any LLM provider for QE advisory tasks. Route simple questions to cheaper models, keep complex reasoning on premium providers, and let the fleet automatically route around outages. Sensitive data is scrubbed before prompts leave your environment. (ADR-092)

Added

  • Multi-provider advisor routing — Distribute advisory tasks across Claude, OpenAI, Ollama, OpenRouter, or any compatible provider. Route by task complexity, cost, or provider health. If one provider goes down, the fleet routes around it automatically.
  • Automatic PII redaction — API keys, credentials, secrets, and PII are stripped from prompts before they reach any external advisor. Three modes: strict (credentials + PII), balanced (credentials only), off (for self-hosted like Ollama).
  • Per-provider circuit breakers — Detect provider degradation and stop sending requests before they time out. Automatic recovery probes re-enable providers when they come back.
  • aqe llm-router CLI command — Inspect provider health, circuit breaker state, routing weights, and configuration.
  • 8 QE agents upgraded — coverage-specialist, fleet-commander, pentest-validator, queen-coordinator, risk-assessor, root-cause-analyzer, security-auditor, and test-architect all support multi-provider routing out of the box.

Fixed

  • Distribution pipeline edge cases when multiple providers respond simultaneously
  • Error handling in routing-feedback collection

Changed

  • Queen coordinator now delegates advisory tasks through the advisor routing layer
  • Tiny-dancer router gains an advisor fallback path for when primary routing is unavailable

[3.9.9] - 2026-04-09

This release ships qe-browser — a new fleet skill that gives every QE agent a real browser through a ~10MB Go binary instead of a 300MB Playwright install. Built on Vibium (WebDriver BiDi) and shipped under ADR-091.

Added

  • qe-browser fleet skill (ADR-091) — Browser automation for QE agents with 5 helper scripts:
    • assert.js — 16 typed assertion kinds (url_contains, selector_visible, no_console_errors, element_count, title_matches, etc.)
    • batch.js — Multi-step execution with pre-validation, stop-on-failure, and delegation to assert.js
    • visual-diff.js — Pixel-perfect baseline comparison with pixelmatch, hash fallback, configurable threshold
    • check-injection.js — 14-pattern prompt-injection scanner ported from gsd-browser (MIT/Apache-2.0) with --exclude-selector for docs sites
    • intent-score.js — 15 semantic intents (submit_form, accept_cookies, fill_email, primary_cta, etc.) ported from gsd-browser
  • Vibium auto-installaqe init now installs the vibium CLI globally via npm during phase 09 with a pre-flight short-circuit when it's already on PATH (no banner on the common case).
  • Typed missing-browser contract — When vibium is not on PATH, helpers emit a structured status: "skipped" envelope with top-level vibiumUnavailable: true, output.reason: "browser-engine-unavailable", and exit code 2 (distinct from 0=success and 1=failed). Downstream skills can branch on the flag instead of grepping error strings.
  • Linux ARM64 workaround documentation — Chromium symlink recipe for aarch64 Debian/codespace hosts where Google doesn't publish Chrome for Testing (verified against chromium 146.0.7680.177-1~deb12u1).
  • 7-gotcha migration guide (references/migration-from-playwright.md) — Covers headless default, screenshot output directory quirk, absent --selector flag, eval --stdin last-expression contract, ARM64 install, viewport determinism, and first-install download time.
  • End-to-end smoke test (scripts/smoke-test.sh) — 10 test cases against pinned httpbin.org fixtures, including a tc011 that spawns helpers with a stripped PATH to verify the missing-vibium contract.
  • 103 unit tests across 8 files covering assertion kinds, batch validation, check-injection patterns, intent-score whitelist, fixture server path traversal, and the missing-vibium end-to-end contract.

Fixed

All fixes below are from a devil's-advocate review of the initial qe-browser implementation, captured in ADR-091 Phases 1 through 4:

  • Assertion fail-closed on missing telemetryrunConsoleCheck/runNetworkCheck used to fail-OPEN when the underlying vibium console/vibium network JSON was unavailable (silently reporting no_console_errors: pass when we couldn't tell). Now returns a typed unavailable sentinel that runCheck surfaces as passed: false, unavailable: true, per feedback_no_unverified_failure_modes.md.
  • intent-score.js special-character corruption — The script builder used String.prototype.replace with a raw substitution string, so scopes containing $&, $`, $', or $1-$9 corrupted the generated browser-side code. Switched to split/join for literal substitution.
  • visual-diff.js unsupported --selector — The vibium screenshot --selector flag does not exist in v26.3.x. Replaced the dead fallback path with an explicit error pointing at ImageMagick convert -crop.
  • vibium screenshot -o directory ignored — Vibium hardcodes ~/Pictures/Vibium/<basename> regardless of the -o argument's directory. visual-diff.js now reads from Vibium's actual output path and copies to the caller's requested location.
  • vibium eval --stdin return contract — Vibium eval returns the LAST EXPRESSION value via {"ok":true,"result":"<stringified>"}, not console.log output. Added unwrapEvalResult() that parses the result string back, and removed console.log wrappers from all helper scripts.
  • Headless container support — Vibium defaults to "visible browser" and fails with Missing X server or $DISPLAY on headless containers. All helper scripts now auto-inject --headless into every vibium invocation (opt out via QE_BROWSER_HEADED=1).
  • parseArgs --key=value form — Previously only --key value (space-separated) was parsed. A user typing --threshold=0.05 got args["threshold=0.05"] = true and the real threshold key stayed undefined. Now splits on the first = so both forms work and URL/base64 values containing = survive intact.
  • batch.js no pre-validation — A typo in step 17 used to surface AFTER steps 1-16 had executed with side effects. Added validateAllSteps() that walks every step's required fields before the first vibium call and aborts with a consolidated error listing all typos.
  • check-injection.js ANSI escape passthrough — Finding snippets included raw page text verbatim, so malicious pages could inject terminal control sequences that trigger on cat findings.json. Added sanitizeSnippet() that strips C0 controls (0x00-0x1F except \t\n) and DEL (0x7F).
  • check-injection.js doc false positives — Running the scanner on docs that talk about prompt injection self-flagged every heading. New --exclude-selector "main, .docs-content" strips subtrees from a cloned <body> before scanning; live page unchanged.
  • intent-score.js bare-x false positives — The close_dialog regex used a bare /x/ that matched "fix", "exit", "extra", "sixteen". Anchored with \bx\b; Unicode × and unchanged.
  • Fixture HTTP server bound to 0.0.0.0 — Codespaces auto-forward 0.0.0.0 ports to the public preview URL, so running fixtures/serve-skills.js was silently exposing the skills tree. Default is now 127.0.0.1; QE_BROWSER_FIXTURE_HOST=0.0.0.0 is explicit opt-in.
  • Fixture server path-traversal guard — The startsWith(SKILLS_ROOT) check false-passes on sibling dirs that share a prefix and is fragile on Windows mixed separators. Replaced with path.relative() + .. check (the canonical guard).
  • detectVibium stderr-only semvervibium --version emits to stderr on some platforms. detectVibium now reads both stdout and stderr and extracts the semver with a regex that handles prerelease/build metadata.
  • installBrowserEngine silent 1-3 minute freezespawnSync('npm install -g vibium') blocks for 1-3 minutes on cold caches while Chrome for Testing downloads. Phase 09 now runs a pre-flight detect that short-circuits when vibium is already on PATH (no banner) and logs a "this can take 1-3 minutes on first run" message BEFORE the spawn on the cold path.
  • 09-assets.ts dead error catch — The installBrowserEngine try/catch re-emitted raw errors with no recovery path. Wrapped with actionable guidance pointing at npm install -g vibium and a re-run of aqe init.

Changed

  • .gitignore — Added .aqe/ for per-project qe-browser state (visual baselines and helper caches), with !.aqe/visual-baselines/.gitkeep carve-out so projects that opt in to committing baselines can do so by removing the ignore.
  • 11 skills migrated to reference qe-browsera11y-ally, e2e-flow-verifier, qe-visual-accessibility, security-visual-testing, visual-testing-advanced, testability-scoring, compatibility-testing, accessibility-testing, localization-testing, observability-testing-patterns, enterprise-integration-testing. Each SKILL.md now points at .claude/skills/qe-browser/ instead of embedding Playwright snippets.
  • Skill counts bumped across user-facing docs — README headline 74 → 75, Tier 3 48 → 49, .claude/skills/README.md total 84 → 85, V3 Domain Skills 23 → 24. skills-manifest.json bumped to manifest version 1.4.0 with a new browser-automation category, fleetVersion: "3.9.9". trust-tier-manifest.json bumped tier3: 49 → 50, total: 112 → 113.

Verified

  • Fresh aqe init --auto in /tmp/qe-browser-uat against the local build — 85 skills / 60 agents installed, Browser engine: vibium 26.3.18 (already installed) logged cleanly.
  • 12 user-perspective checks against the installed skill — navigate + assert on httpbin, --threshold=0.42 form, batch.js pre-validation aborting on typos, intent-score.js submit_form, check-injection.js --exclude-selector (visibleChars 3595 → 35), fixture server banner (127.0.0.1), path traversal returns 404, missing-vibium fallback, installed smoke-test.sh 10/10, idempotent re-init, JSON envelope contract.
  • Unit tests — 103 tests across 8 files, all passing: qe-browser-assert, qe-browser-batch, qe-browser-check-injection, qe-browser-intent-score, qe-browser-vibium-lib, qe-browser-fixtures-server, qe-browser-unavailable-e2e, browser-engine-installer.
  • Smoke test — 10/10 against real Vibium v26.3.18 + Chromium 146.0.7680.177 + httpbin.org pinned fixtures.

[3.9.8] - 2026-04-08

This is a release-process release. No source code changes — every commit since v3.9.7 lands in CI, fixtures, scripts, or docs. The published package is functionally identical to v3.9.7 except for a refreshed lockfile with two transitive security patches.

Added

  • Mirror init-corpus tarballs to GitHub Releases (#411, #415) — Insurance against codeload.github.com regenerating its git archive output (has happened in 2023 and 2024). The release-gate's setup.sh now falls back to a self-hosted mirror at the init-corpus-v1 release on primary-URL sha256 mismatch and emits a loud WARNING: using mirror for <id> line so CI surfaces drift even on green runs. New scripts/upload-init-corpus-mirror.sh for the maintainer (idempotent, refuses to upload bytes that don't match MANIFEST.json). New .github/workflows/init-corpus-mirror-test.yml exercises both the reachability path (AQE_CORPUS_FORCE_MIRROR=1) and the fallback-on-drift path (local python3 -m http.server serving bogus bytes) on every PR touching the corpus and weekly on Mondays.

  • PR template CI enforcement (#408, #416) — Replaces the honor-system #401 failure-modes checkbox with a real CI parser. .github/workflows/pr-template-check.yml runs on every PR and hard-fails when (a) the load-bearing checkbox is unchecked or its template section is deleted, or (b) the PR body contains dismissal phrases like "I believe it's unlikely" or "highly unlikely" without a same-paragraph tracking issue reference. 11 forbidden-phrase patterns covered. dependabot[bot] allowlisted via job-level if: so machine-generated PRs don't fail the check. The parser is scripts/check-pr-body.cjs (zero deps, ESM-safe via .cjs extension). 11 fixtures under tests/fixtures/pr-body/ cover valid bodies, invalid bodies, multi-violation bodies, and the actual v3.9.3 PR body (which fails on missing section) plus a synthetic body quoting #401's exact postmortem reference. A self-test job runs the parser against every fixture in CI to catch parser regressions.

  • Weekly init chaos workflow (#410, #417) — Adversarial-rare coverage to complement the everyday-real release gate. .github/workflows/init-chaos.yml runs Sundays 05:00 UTC. tests/fixtures/init-chaos/generate.sh produces 6 pathological project shapes at runtime: UTF-16LE source with BOM, mixed line endings, mutual symlink loop, PNG bytes saved as .ts, ~256 KB single-line minified bundle, and source files with embedded NUL/ESC sequences. For each shape the workflow runs timeout 60 aqe init --auto --json and asserts the exit code is anything except 124 (the timeout's signal that init hung). The watchdog is the load-bearing thing under test, not init's ability to make sense of garbage input.

  • docs/VERIFICATION.md (#409, #417) — Maintainer-facing entry point for the post-#401 release verification layer. Architecture diagram, how to interpret a failed gate, how to add a fixture, how to embed the verification matrix into a release notes file. Linked from CONTRIBUTING.md Documentation section.

  • scripts/embed-verification-matrix.sh (#409, #417) — Status-only matrix script. Given a workflow run ID, downloads the init-corpus-logs artifact via gh run download, parses summary.txt, and emits a markdown table. Used by maintainers when writing per-version release notes.

Changed

  • docs/policies/release-verification.md rewritten around the automated gate (#409) — The pre-#401 manual aqe init checklist is removed; the gate now does what it tried to do, with 22 assertions per fixture. The Version Update Policy + Workflow sections are preserved intact — they cover the one class of pre-release error the gate cannot catch.

  • tests/fixtures/init-corpus/setup.sh restructured around a download_and_verify helper to support the primary→mirror fallback path, with proper set -e exemption via if func; then ... else rc=$? ... fi so the fallback can actually fire. Added AQE_CORPUS_MANIFEST_PATH and AQE_CORPUS_FORCE_MIRROR env overrides for the mirror-test workflow.

Security

  • Transitive dependency bumps (#414) — hono 4.12.9→4.12.12 and @hono/node-server 1.19.11→1.19.13 (both indirect, lockfile-only). Picked up by dependabot's npm_and_yarn security group.

[3.9.7] - 2026-04-07

Added

  • Release-gate corpus with real public repo fixtures (#401, #412) — tests/fixtures/init-corpus/ now contains 4 pinned real-public-repo fixtures that run aqe init --auto end-to-end before every npm publish. This is the structural verification layer the v3.9.1v3.9.4 init regression series exposed as missing. The corpus includes developit/mitt (tiny TS), sindresorhus/p-queue (mid-size TS), ruvnet/RuView (multi-lang, with examples/ruview_live.py sha256-pinned to the exact 28,745-byte content that triggered the v3.9.4 hang), and agentic-qe itself as the dogfood case. 22 assertions per fixture including per-step JSON error inspection, snapshot-based KG thresholds with tolerance, skills/agents/MCP/CLAUDE.md/workers/config.yaml presence checks, subthreshold stall detection, and a second init pass that exercises phase 06's delta-scan path — the actual surface that hung in v3.9.1 ruview and was never reached on a first init.

  • aqe init --json structured output (#412) — new flag emits the full InitResult as machine-readable JSON with schemaVersion: 1, stable per-phase steps[], and aggregate summary. Exit code is stricter in --json mode: non-zero on any step error, not just critical-phase failures. This is the stable contract the release gate and future CI consumers rely on instead of grepping stdout for human banners.

  • Phase 06 watchdog effectiveness unit test (tests/unit/init/phases/code-intelligence-watchdog.test.ts) — 4 cases proving the async-stall branches of runBoundedScan actually work (per-file timeout, per-file error recovery, phase-level cap) plus explicit documentation of the sync-block limitation that requires AQE_SKIP_CODE_INDEX or future worker isolation.

  • Pre-publish-gate CI job (.github/workflows/npm-publish.yml) — runs the corpus against the freshly-built tarball before publish. Blocks the release tag on any gate failure.

  • Post-publish canary workflow (.github/workflows/post-publish-canary.yml) — fires only on real publishes (filtered against workflow_dispatch dry-runs), polls the actual npm CDN via npm install --dry-run (not npm view which only hits registry metadata), runs the corpus against the published package, opens a P0 issue via gh issue create --body-file if any fixture fails.

  • Pull request template (.github/PULL_REQUEST_TEMPLATE.md) with a single load-bearing checkbox: every failure mode in a PR description must have a test or a linked tracking issue. Honor-system today; CI enforcement tracked in #408.

Fixed

  • Phase 06 no longer hides non-critical failures behind result.success: true (#412) — runCodeIntelligenceScan previously had a top-level catch that returned {status: 'skipped', entries: 0} on any throw, producing a successful phase result with hidden failure semantics. Init would report "AQE v3 initialized successfully" while the KG was empty and the user had no signal. The catch is gone; exceptions now propagate to BasePhase.execute() and appear as step.status='error' in the result, visible to both the user and the release gate. This is the exact failure shape that v3.9.3 shipped with — now structurally impossible to ship silently.

  • Resource leak in phase 06 cleanup path — the old runCodeIntelligenceScan only cleaned up kgService and memory handles on the success branch. On any throw, those native handles (better-sqlite3 + hnswlib-node + KG service) leaked and could cause database is locked or stale-connection failures in subsequent init phases or in aqe code index runs. Now released via try/finally, guaranteed even on throw.

Changed

  • AQE_SKIP_CODE_INDEX promoted to permanent supported flag. Originally added in v3.9.4 as an emergency escape hatch during the ruvector deadlock, this flag is now formally documented as a permanent defense-in-depth option in code comments, CLI help, and the phase interface type. The underlying deadlock was fixed by ADR-090 in v3.9.6; the flag stays as the user's break-glass if verification ever misses a future native stall.

  • tests-on-tag-sha job simplified (.github/workflows/npm-publish.yml) — previously tried to skip re-running tests when optimized-ci.yml had already passed on the same SHA, via a gh api conditional. Devils-advocate review found four failure modes in that conditional (matrix partial-success, head SHA drift, rate limit, file rename). Replaced with an unconditional fast unit test run on release events only (~2 min added, no API calls, no race conditions).

Deferred (tracking issues)

The following items from the #401 Part 2 proposal are deferred with explicit tracking issues rather than dropped silently:

  • Phase 06 worker_threads.Worker isolation — #407 with defined revisit triggers
  • PR template CI enforcement (branch protection + lint) — #408
  • VERIFICATION.md + release-notes verification matrix — #409
  • Chaos workflow for pathological init inputs — #410
  • Mirror init-corpus tarballs to GitHub Releases — #411

[3.9.6] - 2026-04-06

Fixed

  • Native HNSW search now actually works (#399, ADR-090) — the previous NativeHnswBackend wrapped @ruvector/router 0.1.28's VectorDb, which was found to have four serious bugs: (1) HNSW search returned essentially random results — recall@10 ≈ 010% on textbook unit-Gaussian random vectors, could not find self-vectors; (2) the VectorDb constructor unconditionally wrote a vectors.db redb file to the user's project root, polluting CWD with multi-MB files outside the unified memory architecture; (3) only one VectorDb instance could exist per process due to a process-wide redb file lock; (4) NAPI dispose did not synchronously release the redb lock, which was the root cause of v3.9.5's futex deadlock. NativeHnswBackend was rewritten to wrap hnswlib-node@^3.0.0 (the canonical Yury Malkov C++ Hnswlib reference implementation, used by Pinecone, Weaviate, Qdrant, LangChain, ChromaDB), which fixes all four bugs in one swap. Empirical verification on the same fixture: 100% recall@10 vs @ruvector/router's 10%, faster inserts, multiple instances coexist, no CWD pollution. The useNativeHNSW default is flipped back to true so users with large codebases get sublinear HNSW search by default again. No new dependency was added — hnswlib-node was already in package.json.

  • Code-intelligence semantic search returns correct nearest neighbors. Prior to the migration, every qe-kernel namespace search was going through the broken @ruvector/router HNSW and returning essentially random non-neighbors. Pattern matching, dream insights, and KG search now return the actual nearest neighbors.

Removed

  • vectors.db is no longer auto-created in users' project roots. This was a side-effect of @ruvector/router's VectorDb constructor and existed in violation of the unified memory architecture (CLAUDE.md: "all data goes through SQLite — one DB, one schema"). aqe init now warns when a stale vectors.db is detected from a previous version and tells the user it is safe to delete. It does not auto-delete — per CLAUDE.md data protection rules, AQE never touches .db files without explicit user confirmation. Users can clean up with rm vectors.db.

Added

  • Real-fixture HNSW recall test (tests/integration/ruvector/native-hnsw-real-fixture.test.ts) — loads the project's own qe-kernel namespace from .agentic-qe/memory.db and asserts top-1 == self with recall@10 ≥ 0.9 across 5 deterministic queries against ~2,000 real sentence-transformer embeddings. Plus regression guards for the four @ruvector/router bugs (CWD pollution, concurrent instances, dispose lifecycle, resize past initial capacity).
  • Diagnostic scripts (scripts/diagnose-issue-399*.mjs) — four self-contained scripts that reproduce each of the four @ruvector/router bugs and verify hnswlib-node's correctness on the same fixtures. Kept for any future revisit of the HNSW backend.
  • ADR-090 documenting the migration with the empirical numbers, the four bugs, the rejected alternatives, and the migration path for users with stale vectors.db files.

[3.9.5] - 2026-04-06

Fixed

  • aqe init --auto deadlocks in code intelligence pre-scan on real-world Python files — ROOT CAUSE FOUND. The @ruvector/router native NAPI module (used by NativeHnswBackend) deadlocks on a futex (futex_wait_queue with NULL timeout) when VectorDb.insert() is called against certain vector content shapes. Reproduced locally against examples/ruview_live.py from the RuView project: main thread blocked indefinitely, 17 worker threads (V8 + tokio + libuv) all waiting on futexes that are never released. The setTimeout-based watchdog from v3.9.3 cannot interrupt this because setTimeout callbacks queue between event loop iterations and the event loop is frozen in a kernel futex syscall. v3.9.4's AQE_SKIP_CODE_INDEX escape hatch was the unblock; this release is the actual fix.

    The fix: flip the useNativeHNSW feature flag default from true to false. The JS-only ProgressiveHnswBackend (which v3.9.3 commit 2bd601b0 already routed to brute-force exact cosine for the cosine metric) handles AQE's typical KG sizes (<10k vectors @ 384 dim) faster than HNSW because there's no graph-traversal overhead. Native HNSW only wins above ~100k vectors, which AQE doesn't currently hit.

    Verification:

    • examples/ruview_live.py (28 KB, 776 lines, 95 entities) — was: deadlock, now: 258 ms, 95 entries indexed.
    • 200-file synthetic fixture — was: 672 ms, now: 1761 ms (still fast, slightly higher because brute-force is O(n·d) per add).
    • 1-file fresh fixture — 380 ms total init.
    • All HNSW + memory + init unit tests: 152/152 + 452/452 pass.

    Native HNSW is still available via useNativeHNSW: true in ~/.aqe/feature-flags.json or setRuVectorFeatureFlags({ useNativeHNSW: true }) for users on large indices who have verified the deadlock doesn't trigger on their data. The full architectural fix (running the indexer in a killable worker_threads.Worker so any future native deadlock can be terminated by the parent) is still tracked in #401 for v3.9.6.

Changed

  • Default HNSW backend is now ProgressiveHnswBackend (JS brute-force cosine) — see Fixed section. This is the v3.9.5 hotfix scope. The killable-worker indexer refactor remains v3.9.6 scope.

[3.9.4] - 2026-04-06

Fixed

  • aqe init governance phase failing with x Install governance configuration (1ms)governance-installer.ts used the same brittle fixed-depth __dirname + '../..' path traversal pattern that Fix 4 in v3.9.3 repaired for findMcpEntry(). When the installer code is bundled into a chunk under dist/cli/chunks/chunk-XXX.js (esbuild code-splitting, v3.9.0+), __dirname points to the chunks directory and the traversal lands outside the package. The constructor throws "Governance assets not found" and the phase fails in 1 ms. getGovernanceAssetsPath() now walks up to the nearest package.json with name=agentic-qe via findPackageRoot() — the same helper v3.9.1 added for skills and agents installers. Same pattern fix also applied to kiro-installer.ts and src/cli/commands/sync.ts (which had the same bug on opt-in code paths).

  • aqe init --auto hang in phase 06 with no diagnostic output — v3.9.3's phase-level watchdog uses Promise.race with setTimeout, but setTimeout callbacks can only fire between Node event loop iterations. When a synchronous native call inside the indexer (e.g. @ruvector/router's VectorDb.insert stalls on a specific vector shape on an overlay filesystem) blocks the event loop, the timer callback never runs and the 180 s phase cap never triggers. This is the "worst case" I flagged in the v3.9.3 PR description that proved real on the ruview codespace. A proper fix (running the indexer in a killable worker_thread or child_process.fork) is tracked for v3.9.5 — see the tracking issue. In the meantime, v3.9.4 ships two mitigations:

Added

  • AQE_SKIP_CODE_INDEX=1 environment variable — bypasses phase 06 entirely when set. Users in codespaces whose init stalls can run AQE_SKIP_CODE_INDEX=1 aqe init --auto to unblock immediately. KG lookups still work on demand via aqe code index and aqe memory search.

  • --skip-code-index flag on aqe init — interactive equivalent of the env var above. Works with all init modes (--auto, wizard, upgrade).

  • Per-file progress logging in phase 06 — the indexer now logs every file before it starts processing it, not every 100 files. Output format: [123/349] src/path/to/file.ts. When a stall happens, the last line of output names the exact file the indexer was working on — which is the diagnostic evidence we need to target a permanent fix. On clean runs this adds ~349 lines for a ruview-sized project, which is trivial for a one-time init command and a large win for observability.

Changed

  • Progress log format during indexing — replaced "every 100 files" summary log with per-file [i/N] path lines. Final Indexed N entries summary at phase end is unchanged.

[3.9.3] - 2026-04-06

Fixed

  • aqe init --auto hangs at "Code intelligence pre-scan" — v3.9.2's fix only addressed the AQELearningEngine → getSharedRvfDualWriter deadlock, but the phase 06 hang in real projects (ruview, cf-devpod) had a different root cause: the indexer had no per-file or whole-phase timeout, so a single pathological file or a native-layer stall on overlay filesystems blocked the CLI indefinitely with no diagnostic. Phase 06 now drives indexing file-by-file with a 30 s per-file cap and a 180 s whole-phase cap. Partial results are preserved on timeout, the warning names the exact file responsible, and init continues. Progress lines log every 100 files so users can see where the indexer actually is.
  • aqe init --auto leaves cosmetic errors in the output — Phase 10 workers spawned aqe mcp as a detached child to "pre-warm" the MCP daemon, but that spawn raced the parent for file locks and emitted a cascade of misleading errors: [RVF] Shared adapter init failed: FsyncFailed, VectorDb creation failed: Database already open, Error: Could not find MCP server entry point. None of these were real failures — the daemon was never needed, because Claude Code starts the MCP server on demand via .mcp.json. The spawn has been removed entirely. Phase 10 now completes in ~1 ms instead of 1500 ms.
  • aqe mcp --help / aqe mcp fails with "Could not find MCP server entry point" — v3.9.0's esbuild code-splitting (lazy-load CLI handlers) placed CLI chunks under dist/cli/chunks/, breaking the fixed __dirname + '..' paths the MCP command used to locate dist/mcp/bundle.js. A regression of the v3.7.10 fix. findMcpEntry() now walks up to the nearest package.json with name=agentic-qe via the existing findPackageRoot() helper, with legacy sibling-path fallback for dev mode and an extra chunk-split candidate.
  • Every CLI command opens patterns.rvf and memory.db at startupbootstrapTokenTracking() was creating an RvfPatternStore (which auto-attached a SQLitePatternStore, which initialized UnifiedMemory) before commander had parsed argv, so aqe --version, aqe --help, and aqe init all grabbed exclusive file locks they never used. This is what was holding the locks that cf-devpod's spawned daemon then fought with. TokenOptimizerService.initialize() is now a lazy registration — it stores the memory backend reference and config but defers pattern-store creation until the first checkEarlyExit() or storePattern() call. Commands that never touch the optimizer no longer open any files. aqe --version on a project with an existing .agentic-qe/ directory now prints a single line instead of 6+ lines of bootstrap noise.

Added

  • Phase 06 per-file and phase-level watchdogs — Configurable via PER_FILE_TIMEOUT_MS (30 s) and PHASE_TIMEOUT_MS (180 s) constants in src/init/phases/06-code-intelligence.ts. New CodeIntelligenceResult.status = 'timeout' variant with timeoutFile diagnostic field. Progress logged every PROGRESS_LOG_INTERVAL (100) files.
  • IHnswIndexProvider.dispose() contract — Optional dispose() method for backends to release native resources. NativeHnswBackend.dispose() nulls the nativeDb reference so NAPI GC can reclaim the Rust-side index. ProgressiveHnswBackend.dispose() is a no-op. HnswAdapter.close(name) now invokes the backend dispose chain for tests and explicit shutdown.
  • Lazy TokenOptimizerService lifecycleensurePatternStoreReady() is a private idempotent method invoked on first use by checkEarlyExit() and storePattern(). Concurrent callers share one readyPromise. Failure leaves the service in a "registered but unready" state that degrades to session-cache-only mode.

Changed

  • Phase 10 Workers no longer spawns MCP daemon — The startDaemon() / findMcpCommand() helpers have been removed. Users who want to run the MCP daemon manually can still use the generated .agentic-qe/workers/start-daemon.cjs helper script. Phase 10 continues to write the worker registry and individual worker configs.
  • TokenOptimizerServiceImpl.initialize() is now idempotent in both directions — Calling it twice is still a no-op when initialized=true, but when initialized is externally reset to false (tests), the next initialize() call proactively clears stale readyPromise / patternStore / optimizer state to avoid picking up references to disposed memory backends.

Verification

  • 17/17 token-optimizer-service tests pass.
  • 99/99 HNSW tests pass (native-hnsw-backend, hnsw-legacy-bridge, hnsw-unification).
  • 53/53 unified-memory tests pass.
  • 65/65 pattern-store / rvf-pattern-store tests pass.
  • 32/32 init orchestrator + database-phase tests pass.
  • Empty-project fixture: init completes in 436 ms (v3.9.2: 1787 ms) with zero errors.
  • 200-file fixture: init completes in 621 ms with progress logs at 100/200 and 200/200.
  • 15 k-entity heavy fixture: init completes in 2167 ms (v3.9.2: 3401 ms).
  • Pre-existing .agentic-qe/ + aqe --version: prints single line 3.9.3, does not create patterns.rvf.
  • aqe mcp --help exits 0 with usage text (v3.9.2: "Could not find MCP server entry point").

[3.9.2] - 2026-04-06

Fixed

  • aqe init --auto hangs at "Code intelligence pre-scan" — After v3.9.1 flipped useRVFPatternStore to true by default, AQELearningEngine.initialize() would open patterns.rvf twice in the same process: once via createPatternStore() and again via getSharedRvfDualWriter()getSharedRvfAdapter(). The native @ruvector/rvf-node binding acquires an exclusive file lock on open, so the second call deadlocked waiting for a lock the same process already held. createPatternStore() now routes through the getSharedRvfAdapter() singleton so only one handle to patterns.rvf exists per process.
  • CLI process doesn't exit after aqe init completes — Native NAPI handles from @ruvector/rvf-node and @ruvector/router kept the event loop alive indefinitely, and cleanupAndExit()'s async dynamic imports for cleanup loaded even more native bindings before the 3-second force-exit timer could fire. cleanupAndExit() is now synchronous: best-effort fire-and-forget disposes followed by immediate process.exit(). Init now completes and exits cleanly in ~7 seconds.

Changed

  • RvfPatternStore.dispose() respects shared adapters — New skipCloseOnDispose option prevents dispose() from closing an adapter owned by the getSharedRvfAdapter() singleton, so other consumers (dual-writer, migration adapter) retain access to the shared handle.

[3.9.1] - 2026-04-05

Added

  • RVF persistent vector storage (ADR-065/066)RvfPatternStore backed by @ruvector/rvf-node native HNSW replaces in-memory index rebuild on startup. Cold-start drops from seconds to <2ms; search p50 under 0.2ms. Factory routing via createPatternStore() with automatic fallback to SQLite.
  • Agent memory branching (ADR-067) — Per-agent COW isolation via RvfNativeAdapter.derive() with ingest-log merge on completion and automatic branch cleanup on failure. Wired into DefaultAgentCoordinator spawn/complete lifecycle.
  • Dream RVF COW (ADR-069) — Dream engine uses RVF forks instead of SQLite savepoints when RVF is active. Child adapter lifecycle managed with temp file cleanup. Recall validation gate compares top-k overlap before merge.
  • HNSW unification (ADR-071) — Three separate HNSW implementations (InMemoryHNSWIndex, HNSWEmbeddingIndex, HNSWIndex) unified through HnswLegacyBridgeHnswAdapter. Shadow validator confirms <2% divergence. Old implementations decommissioned.
  • RVF dual-write migration (ADR-072)RvfMigrationAdapter with 5-stage routing (SQLite-only → dual-write → RVF-primary). RvfConsistencyValidator tracks rolling divergence. RvfStageGate enforces go/no-go criteria with witness chain. Stage 2 (dual-write, SQLite reads) active by default. MCP tools: migration_status, migration_check, migration_promote.
  • StrongDM software factory (ADR-062) — Loop detection wired to MCP protocol-server (blocks on strike 3+), holdout testing (10% FNV-1a selection), gate ratcheting (monotonic 5-pass/2%/95% cap), progressive context (TF-IDF prediction), and meta-learning cycles (4 insight types).
  • RuVector advanced capabilities (ADR-087) — EWC++ outcome recording wired to 3 domain coordinators, HDC fingerprinting (10K-bit hypervectors), delta event sourcing, cognitive routing (predictive compression), and hyperbolic HNSW (Poincare ball).
  • HnswShadowValidator — Brute-force vs HnswAdapter divergence validation for search consistency verification.
  • RvfMigrationCoordinator — Wires migration adapter, consistency validator, and stage gate with real SQLite/RVF handles. Initializes on kernel boot when migration stage >= 2.
  • Shared RVF adapter singleton — Eliminates dual file handles between kernel and dream engine.
  • 500+ new tests — Covering RVF pattern store, agent memory branching, HNSW bridge, shadow validator, migration adapter, consistency validator, stage gate, StrongDM tiers, and RuVector capabilities.

Fixed

  • require() fails in ESM bundles ("Dynamic require of X is not supported") — esbuild's CJS compatibility shim throws in ESM chunks because require is undefined. Added createRequire banner to both CLI and MCP build scripts so every chunk has a working require. Fixes RVF, sqlite, and all native module paths in the CLI.
  • aqe init path resolution — Skills and agents installers now resolve paths from package root via findPackageRoot() instead of brittle relative traversals that broke under esbuild code-splitting chunk layouts.
  • quality_assess hangs on large projects — Defaults to src/ instead of cwd; discoverSourceFiles skips .agentic-qe/.claude/.cache dirs with maxFiles=5000 cap.
  • Dream cycle empty-queryRvfPatternStore returns all patterns from SQLite when query is empty.
  • Coherence integration fallbackRvfPatternStore computes brute-force cosine over SQLite embeddings when RVF adapter unavailable.
  • 7 pre-existing test failures resolved — Fixed console spy targets, ADR-062 loop detection in MCP tests, dream cycle RVF paths, and coherence vector search fallback.

Changed

  • @ruvector/gnn bumped 0.1.19 → 0.1.25 — Latest ProgressiveHnswBackend improvements.
  • 3 RVF feature flags default to trueuseRVFPatternStore, useAgentMemoryBranching, useUnifiedHnsw all ship enabled (opt-out via config).
  • RVF migration stage default: 2 — Dual-write with SQLite as source of truth for reads. Stage promotions (3, 4) gated by observation periods.
  • ESM-safe dynamic importsrequire() replaced with import() in dream-engine and branch-manager.

[3.9.0] - 2026-04-02

Added

  • CC-internals improvements (IMP-00 through IMP-10) — 11 production-hardening improvements across 4 priority tiers with 466+ new tests across 37 test files.
  • 4-tier context compaction pipeline — Progressive memory compaction with microcompact (tier 1), session summary (tier 2), LLM compact (tier 3), and reactive eviction (tier 4). Context budget tracking prevents overflows.
  • Plugin architecture — Extensible plugin system with lifecycle management, manifest validation, dependency resolution, security sandboxing, and caching. Supports local, GitHub, and npm plugin sources.
  • QE Quality Daemon — Background quality monitoring service with priority queue, git watcher (Linux polling fallback), coverage delta analyzer, CI monitor, test suggester, nightly consolidation, notification service with SSRF guard, and persistent SQLite-backed memory.
  • Retry engine — Configurable retry mechanism with exponential backoff, jitter, circuit breaker, and per-error-class strategies for resilient service calls.
  • Prompt cache latch — Intelligent prompt caching with field-level latch controls to reduce redundant LLM calls.

  • 8 env var kill switchesAQE_MICROCOMPACT, AQE_RETRY_DISABLED, AQE_SESSION_DURABILITY, AQE_PROMPT_CACHE_LATCH, AQE_FAST_PATHS, AQE_HOOKS_SSRF_DISABLED, AQE_COMPACTION_DISABLED, AQE_PLUGINS_DISABLED for granular feature control.
  • aqe daemon CLI commands — Start, stop, and manage the QE Quality Daemon from the command line.
  • aqe plugin CLI commands — Install, list, and manage plugins from the command line.

Changed

  • Lazy-load CLI handlers — Heavy imports (kernel, coordination, workers, unified-memory) are now deferred until command execution. Reduces CLI startup cost by avoiding eager module resolution.
  • esbuild code splitting — CLI build now uses chunk output with splitting enabled for smaller initial bundles.
  • CLI index refactored — Extracted workflow command into dedicated module, added lazy-registry for on-demand handler loading.

Fixed

  • Internal log leak to stdout — Redirected [ParserRegistry], [ContinueGateIntegration], and timestamped internal logs to stderr so they don't interfere with structured CLI output.

[3.8.14] - 2026-03-31

Fixed

  • Security: SQL injection in witness-chain LIMIT/OFFSET — Parameterized LIMIT and OFFSET values in getEntries() query instead of string interpolation. Also handles offset-without-limit correctly via SQLite LIMIT -1 idiom, and limit=0 now properly returns zero rows.
  • Removed @faker-js/faker from 7 production generator files — Replaced with lightweight test-value-helpers.ts using only node:crypto. Eliminates ~6 MB runtime dependency for npm consumers. Generators now work without devDependencies installed.
  • aqe init hook paths break from subfolders — Adopted CLAUDE_PROJECT_DIR pattern so hook commands resolve correctly regardless of working directory.
  • Removed ruflo permissions from aqe init — Only AQE-specific entries are injected into user settings; third-party tool permissions no longer leak in.
  • Dead MCP server.ts removed (911 lines) — Eliminated unused dual-server divergence risk; production uses MCPProtocolServer via entry.ts.
  • CI publishes without test gate — Added mandatory unit test pass gate to npm-publish.yml. Removed continue-on-error from optimized-ci.yml test steps.
  • ESLint broken in ESM project — Renamed .eslintrc.js to .eslintrc.cjs for CommonJS compatibility.
  • Hardcoded version 3.0.0 in MCP serversprotocol-server.ts and http-server.ts now read version dynamically from package.json.
  • Vitest process hang on native modules — Added worker-level afterAll force-exit and global teardown safety net for better-sqlite3 / hnswlib-node handles.

Added

  • test-value-helpers.ts — Zero-dependency test data generator for test-generation domain using node:crypto built-ins with range guards for edge cases.
  • Pagination edge case testslimit=0, offset-without-limit, and offset-beyond-total coverage in witness-chain tests.
  • 17 unit tests for test-value-helpers — Covers all value generators including boundary inputs and inverted ranges.

[3.8.13] - 2026-03-30

Added

  • Code intelligence CLI commands — New aqe code complexity action with cyclomatic, cognitive, and Halstead metrics, hotspot detection, and JSON output. New --incremental and --git-since <ref> flags for aqe code index enabling git-aware incremental indexing.
  • Code intelligence section in README — CLI Reference now documents all 7 aqe code commands with usage examples.

Fixed

  • Security: command injection in --git-since — Replaced execSync with execFileSync to prevent shell injection via user-supplied git refs (CWE-78).
  • Control flow bug in complexity action — Added missing return after cleanupAndExit() calls that could cause null-pointer crashes.
  • Stale CLI references across 20 files — Replaced non-existent aqe kg commands with correct aqe code syntax in all skill files, eval configs, docs, and catalogs. Fixed phantom agent names (qe-knowledge-graph, qe-semantic-searcher) with actual agents (qe-kg-builder, qe-code-intelligence, qe-impact-analyzer, qe-code-complexity). Replaced ruflo doctor --fix with aqe health / aqe init across CLAUDE.md, skills, and docs.
  • aqe init MCP server setup — Restored MCP server initialization as default behavior during aqe init --auto.
  • Tool-scoping tests — Added hypergraph_query to all 5 scoped agent roles to match source of truth. Fixed queen-dependency test expectations for agents without inline MCP references.
  • --depth validation — Now validates the --depth flag is a positive integer instead of silently passing NaN.

Changed

  • Batched complexity analysis — File analysis uses Promise.all with batch size of 8 instead of sequential processing.
  • Shared source extensions — Exported SOURCE_EXTENSIONS from file-discovery.ts to prevent divergence between full scan and --git-since paths.

[3.8.12] - 2026-03-29

Added

  • RuVector Phase 5 — Pattern Intelligence (ADR-087) — HDC pattern fingerprinting with 10K-bit binary hypervectors for O(1) XOR-based similarity, CUSUM drift detection across all 4 coherence gate types, and delta event sourcing with rollback via SQLite. EWC++ three-loop activation wired into quality-assessment, test-generation, and contract-testing coordinators.
  • RuVector Phase 5 — Graph Learning (ADR-087) — GraphMAE self-supervised learning with SPSA optimizer for masked graph autoencoders, Modern Hopfield networks for exponential-capacity exact pattern recall, and cold-tier GNN training with LRU-cached mini-batch trainer and file-backed larger-than-RAM graphs.
  • RuVector Phase 5 — Scale, Optimization & Advanced Learning (ADR-087) — Meta-learning enhancements (DecayingBeta, PlateauDetector, ParetoFront, CuriosityBonus), PageRank pattern importance scoring with citation graphs, spectral graph sparsification, reservoir replay buffer with coherence-gated admission, E-prop online learning (RL algorithm #10), and Granger causality for test failure prediction.
  • 456 new tests across 11 test files covering all Phase 5 milestones with performance benchmarks.

Fixed

  • HDC pre-filter dropping search results — The R1 HDC fingerprint pre-filter in PatternStore search was eliminating candidates with low Hamming similarity instead of just reordering them, causing text searches to return empty results when all candidates had fingerprints.

Changed

  • Coherence gate module extracted from 930-line monolith into 4 focused modules under 500-line limit.
  • RLAlgorithmType union extended from 9 to 10 members (added eprop).
  • Xorshift128 PRNG extracted to shared utility for reuse across RuVector modules.
  • ADR-087 status promoted from Proposed to Active (milestones 1-4 complete).

Security

  • Bumped path-to-regexp from 0.1.12 to 0.1.13 (dependabot).

[3.8.11] - 2026-03-27

Added

  • YAML deterministic QE pipelines — Declarative, token-free quality gates with approval steps, auto-approve timeouts, and 4 built-in SQL-only actions (quality-gate, coverage-threshold, pattern-health, routing-accuracy). Full CLI support via aqe pipeline load/validate/run/list/status/approve/reject.
  • Heartbeat CLI and MCP integration — Manage the token-free heartbeat scheduler with aqe heartbeat status/run-now/history/log/pause/resume and 3 MCP tools. Includes history persistence and daily log viewing.
  • Economic routing model — Quality-per-dollar tier scoring with budget-aware selection, cost-adjusted rewards for the neural router, and EMA-smoothed quality estimates. Opt-in via enableEconomicRouting(). CLI: aqe routing economics/accuracy/metrics. MCP: routing_economics.
  • Session operation cache — O(1) fingerprint-based cache for repeated operations, running before HNSW similarity search. SHA-256 fingerprinting with TTL, capacity eviction, and cross-session persistence via SQLite. Delivers 40-60% token savings on repeated tasks.

Fixed

  • Path traversal in heartbeat log — CLI heartbeat log --date now validates date format (YYYY-MM-DD) to prevent directory traversal attacks, matching the MCP handler's validation.
  • Approval gate cleanup — Pending approval gates are now properly resolved when a workflow is cancelled, preventing timer leaks and dangling promises.
  • Economic config validation — Routing config weights are clamped to valid ranges and normalized to sum to 1.0, preventing score inflation from invalid inputs.
  • Sort mutation in tier selectionselectTier() fallback paths no longer mutate the original scores array, ensuring consistent economicScore descending order in returned results.

[3.8.10] - 2026-03-26

Fixed

  • Coverage data pipeline — Coverage data now flows correctly from test execution through to quality scores. Previously, quality_assess reported fabricated coverage (up to 95%) because it read from keys that nothing wrote to. All 5 orphaned key conventions have been unified into a consistent coverage:latest, coverage:previous, and coverage:file:{path} ecosystem.
  • Test runner coverage collectiontest_execute_parallel now passes --coverage flags to vitest and jest, and reads coverage-summary.json from disk when runners write coverage to files rather than stdout.
  • Per-file coverage storage — Coverage data is now stored via the key-value API (not just the vector store), so quality-analyzer, defect-predictor, and defect-investigation can all read per-file coverage.
  • Coverage trend detectioncoverage:previous is now correctly rotated before each new snapshot, enabling quality-gate trend detection that was previously always reporting "stable".
  • Quality score fairness — Projects without coverage tooling no longer receive a false 25-point quality score penalty. Missing coverage reports as unavailable (-1) rather than 0%.
  • Coverage tracker accuracy — The coverage-tracker worker now reads real data from coverage:latest instead of returning hardcoded fake values.

[3.8.9] - 2026-03-25

Added

  • Multi-language coverage parsers — 6 new parsers for JaCoCo (Java/Kotlin), dotcover (C#/.NET), Tarpaulin (Rust), Go cover, Kover (Kotlin/JVM), and xcresult (Swift/iOS), extending coverage analysis beyond JavaScript/TypeScript.
  • Language-aware agent routing — Agent routing now considers source language when selecting models and strategies, with MCP schema support for the language parameter.
  • RuVector P1 scale benchmarks — Production-scale benchmarks for 10K/100K vector operations, concurrency stress tests, and HNSW memory usage display in aqe ruvector status.
  • Knowledge graph language extensions — Added Swift and C# file extension mappings for broader polyglot code intelligence.

Fixed

  • SHA-256 witness hashing — Replaced insecure djb2 hash with SHA-256 in the witness adapter for cryptographic integrity of coherence proofs.
  • Coherence gate witness persistence — Witnesses are now persisted to the proof envelope, ensuring audit trail continuity across sessions.
  • Hardcoded signing key removed — Eliminated a hardcoded key from the coherence gate; signing keys are now derived from configuration.
  • Benchmark output formatting — Fixed RuVector benchmark result display to correctly report metrics.

[3.8.8] - 2026-03-24

Added

  • aqe memory CLI command — New CLI command with 7 subcommands (store, get, search, list, delete, share, usage) providing full parity with MCP memory tools. Agents and skills can now operate without the MCP server.
  • Web tree-sitter WASM parsers — Added WASM-based parsers for Python, Java, C#, Rust, and Swift, enabling cross-language code intelligence without native binaries.
  • --with-mcp init flag — MCP server configuration is now opt-in during aqe init. CLI commands work standalone without MCP.

Changed

  • MCP dependency eliminated from agents/skills — Migrated 431 mcp__agentic-qe__* references across 230+ agent and skill definitions to use CLI commands (aqe task, aqe agent, aqe fleet, aqe memory, aqe coverage, etc.). Agents now work without an MCP server running.
  • Skill descriptions enriched — 18 QE skill descriptions rewritten with third-person voice, concrete action verbs, and trigger term keywords for better activation and discoverability.
  • Skill names standardized — 15 QE skills renamed to kebab-case format matching their directory names (e.g., "QE Test Generation" to "qe-test-generation").
  • Platform parity — All changes synced across .claude/, assets/, and .kiro/ platform directories.

[3.8.7] - 2026-03-23

Added

  • Hypergraph CLI commands — New aqe hypergraph subcommands (stats, untested, impacted, gaps) for querying the code knowledge hypergraph directly from the terminal.
  • Hypergraph MCP toolhypergraph_query MCP tool exposes the same queries to AI agents, added to 5 agent role scopes.
  • Code index extractor — Shared async batched extractor for functions, classes, interfaces, arrow functions, and method definitions with 12 unit tests.
  • Shell completions for hypergraph — Bash, Zsh, Fish, and PowerShell completion support for hypergraph subcommands.

Fixed

[3.8.5] - 2026-03-21

Fixed

  • Both P1 items from v3.8.3 QE swarm analysis resolved — Closes the highest-priority technical debt identified by the 10-agent parallel quality audit.
  • 401 console. calls replaced with structured logger* — Domain layer now uses the structured logging framework at src/logging/ instead of raw console calls, enabling log levels, structured output, and centralized log management (#374 P1 #8).
  • hooks.ts decomposed from 1,108 lines into 9 handler modules — Cyclomatic complexity reduced from CC=100 to manageable per-handler functions under hooks-handlers/ (#374 P1 #10).
  • 104 test files missing afterEach cleanup — Added proper cleanup to prevent test pollution and reduce flaky test indicators (#374 P2).
  • 11 test files using real setTimeout without fake timers — Added vi.useFakeTimers() to eliminate timing-dependent flakiness (#374 P2).
  • 3 DDD boundary violations in security validators — Moved validators from mcp/security/ to shared/security/ with re-exports for backward compatibility (#374 P2).
  • CI timeout guards — Added timeout 480 to remaining 5 unguarded npm run commands and OS-level timeout guards for hanging tests (#350).

[3.8.4] - 2026-03-19

Fixed

  • Command injection vulnerability (P0) — Replaced exec() with execFile() + allowlist in test-verifier.ts to eliminate CWE-78 shell injection risk.
  • SQL injection surface (P0) — Unified SQL table allowlists across sql-safety.ts, unified-memory.ts, and ruvector/brain-shared.ts; added validateTableName() to all 7 SQL interpolation sites.
  • 70 unguarded process.exit() calls (P1) — Replaced with return/throw in learning.ts (45) and hooks.ts (25) so cleanup handlers execute properly.
  • Database corruption — Rebuilt corrupted memory.db (82 corrupt pages causing 43% dream cycle failures).
  • 15K junk learning patterns — Purged benchmark/test artifacts (bench-*, dream novel_association, test patterns) that inflated pattern counts and degraded quality scoring.
  • Benchmark test isolation — Added useUnified: false to prevent benchmark runs from polluting the production learning database.
  • Statusline pattern inflation — Fixed statusline to count only meaningful patterns instead of including junk and cross-table sums.
  • CI timeouts — Split monolithic CI jobs into parallel shards: Optimized CI into 6 jobs, MCP tests into 4 shards, cutting wall-clock from 25+ min to ~15 min.
  • CI concurrency groups — PRs now cancel stale runs; main branch runs no longer cancel each other on rapid pushes.

Changed

  • Bundle size reduced — Enabled minification: CLI 9.8→6.9 MB (-30%), MCP 12→7.2 MB (-40%).
  • @faker-js/faker moved to devDependencies — ~8 MB savings from production install.
  • Verification scripts hardenedverify:counts, verify:agent-skills, and verify:features now perform real checks with non-zero exit codes on failure.
  • 4 perma-failing scheduled workflows disabled — n8n-workflow-ci, sauce-demo-e2e, qcsd-production-trigger, and benchmark schedules disabled (manual dispatch still available).
  • Quality scoring improved — CLI-hook learning now uses context-aware scoring (source/speed) instead of hardcoded 0.7/0.3.

Added

  • 12 QE swarm analysis reports — Comprehensive v3.8.3 quality audit covering code complexity, security, performance, test quality, SFDIPOT, dependencies, API contracts, architecture/DDD, accessibility, and brutal honesty.

[3.8.3] - 2026-03-18

Fixed

  • Portable hook commandsaqe init no longer embeds the host machine's absolute path into .claude/settings.json hook commands. Commands now use simple relative paths (node .claude/helpers/brain-checkpoint.cjs), making settings fully portable across machines. (#369)
  • SONA persistence initialization — Fixed circular ensureInitialized() call during PersistentSONAEngine._doInitialize() that caused all 31 sona-persistence tests to fail when useSONAThreeLoop flag was enabled by default.
  • RuVector feature flag test compatibility — Updated compressed-hnsw and temporal-compression tests to explicitly set flag state instead of assuming defaults, fixing 9 test failures introduced when v3.8.0 enabled all flags by default.
  • CI timeout and contract test path — Resolved CI workflow timeouts and broken contract test path. (#350)
  • OpenCode config schemaaqe init --with-opencode now generates valid opencode.json matching OpenCode's McpLocal.strict() zod schema (command as string array, environment instead of env, no extra args field). (#370)
  • Infra-healing fallback playbook — Fixed field name mismatches (checkhealthCheck, added verify) in the hardcoded fallback playbook that caused a TypeError on every MCP startup. (#371)
  • Fleet init crashLearningOptimizationCoordinator now gracefully degrades when SONA init fails, matching the other 6 coordinators. Combined with the circular init fix, fleet initialization succeeds on MCP startup. (#372)

Added

  • ADR-086 skill design standards — Major overhaul of all 84 QE skills based on Anthropic's "Lessons from Building Claude Code" skill design guidance. Skills are now folder-based systems with progressive disclosure, gotchas, composition, config, and run history.
  • 5 new skillstest-failure-investigator, coverage-drop-investigator, e2e-flow-verifier, test-metrics-dashboard, and skill-stats fill previously missing categories.
  • 5 on-demand hook skillsstrict-tdd, no-skip, coverage-guard, freeze-tests, and security-watch with executable scripts that activate via slash commands.
  • Gotchas sections — 30 skills now include battle-tested failure data from production learning records.
  • Reference and template files — 10 reference/template files across 7 skills (OWASP top 10, k6 configs, mutation operators, security report templates, etc.).
  • Skill composition — Cross-references added to 10 key skills showing how to chain skills together for complex workflows.
  • Config and run-historyconfig.json with _setupPrompt added to 7 skills; run-history.json with write instructions added to 5 metric-producing skills.

Changed

  • Skill descriptions rewritten — All 84 skill descriptions now use "Use when..." trigger conditions for better auto-detection.
  • Textbook knowledge stripped — 892 lines of generic content removed from 15 skills (26% size reduction) to focus on actionable guidance.
  • 3 redundant skills removedqe-contract-testing (→ contract-testing), qe-security-compliance (→ security-testing), aqe-v2-v3-migration (obsolete). aqe init --upgrade auto-cleans these.
  • Removed tracked generated fileaqe.rvf.manifest.json is now gitignored as it changes every session.

[3.8.2] - 2026-03-17

Fixed

  • YAML frontmatter validation — Removed blank lines inside frontmatter delimiters across 114 SKILL.md files that caused parsers to fail. (#360)
  • OpenCode installer path resolutionaqe init --with-opencode now resolves source paths relative to the package installation directory instead of CWD, fixing 0-agent installs for global npm users. (#361)
  • Settings permissions overwriteaqe init --upgrade now union-merges AQE permissions into existing settings.json instead of replacing the entire permissions array, preserving user-added entries. (#362)
  • Hook path fallback — Brain-checkpoint and statusline hook commands now use a hardcoded absolute path fallback (resolved at install time) instead of pwd, which could resolve incorrectly outside the project root. (#363)
  • Agent updated dateaqe init --upgrade now bumps the updated: field in agent frontmatter when overlays modify content. (#365)
  • Validation pipeline docs — Fixed --steps parameter documentation to consistently describe comma-separated format. (#367)

Added

  • Validation pipeline helper — New .claude/helpers/validation-pipeline.cjs implements the 13-step requirements validation pipeline with sequential execution, gate enforcement, per-step scoring, and weighted category rollup. (#364)

Changed

  • Security scanner dependencyqe-security-scanner dependency on qe-dependency-mapper changed from hard to soft, allowing security scans to start immediately without waiting for the full dependency graph. (#366)
  • Ruflo rebrand — Completed claude-flow to ruflo rename across all remaining skills, helpers, and TypeScript bridge modules with resolveCliPackage() for consistent CLI resolution.
  • CI stability — Resolved CI timeouts, cancellations, and test failures from PR #350.

[3.8.1] - 2026-03-17

Fixed

  • MCP tool prefix mismatch — 8 agent definition files referenced tools using mcp__agentic_qe_v3__ prefix instead of the correct mcp__agentic-qe__ matching the registered MCP server name. This caused agent subagents to fail tool invocations and claude -p to hang waiting for permission approval. (#357)
  • Permission pattern mismatch.claude/settings.json and settings-merge.ts used underscore variant mcp__agentic_qe__* instead of the hyphenated mcp__agentic-qe__*, preventing automatic permission matching for MCP tool calls.

Changed

  • v3.8.0 release notes — Added real benchmark data collected during RuVector integration development (150x HNSW speedup, 9.2x MicroLoRA WASM acceleration, 4x memory reduction).

[3.8.0] - 2026-03-16

Added

  • RuVector native HNSW backend — 150x faster vector search via native HNSW index with metadata filtering, replacing the pure-JS implementation. Searches that took seconds now complete in single-digit milliseconds. (ADR-081)
  • Neural model routing (TinyDancer) — Intelligent router learns which model tier handles each task best, using REINFORCE policy gradient to minimize cost while maintaining quality. Routes simple tasks to fast/cheap tiers automatically. (ADR-082)
  • Coherence-gated agent actions — 3-filter safety pipeline validates agent outputs before they execute, catching hallucinated tool calls and incoherent reasoning chains. Includes witness chain audit trail with SHA-256 hash linking for full traceability. (ADR-083)
  • Cross-domain transfer learning — Agents share learned patterns across test domains (e.g., API testing insights improve UI testing) via Thompson Sampling, accelerating learning on new projects. (ADR-084)
  • Temporal tensor compression — 4x memory reduction for stored embeddings using Int8Array quantization with deterministic golden-ratio dithering for cross-platform reproducibility. (ADR-085)
  • DAG attention scheduler — Dependency-aware test ordering that runs independent tests in parallel while respecting execution order constraints, reducing overall suite time.
  • CNN visual regression — Spatial pooling embeddings for visual diff detection, enabling image-based regression testing without pixel-exact matching.
  • Behavior tree orchestration — Sequence/Selector/Parallel node types for composing complex agent workflows with built-in retry and fallback logic.
  • Reasoning QEC (Quantum Error Correction) — Majority-vote consensus across multiple reasoning paths for higher confidence agent decisions.
  • QE dashboard scaffolding — Browser-based dashboard for exploring learned patterns, cluster visualizations, and WASM-accelerated vector search.
  • Cognitive container export/import (RVF v2) — Portable brain snapshots that capture an agent's full learned state for sharing across environments.
  • 15 feature flags — All new capabilities are enabled by default for immediate value. Disable individually via CLI profiles or setRuVectorFeatureFlags() for opt-out.
  • Regret tracker — Monitors routing decisions over time with log-log regression to detect and correct degrading performance trends.
  • HNSW health monitor — Spectral analysis of index health with automatic rebalancing recommendations.
  • CLI commands — New aqe ruvector, aqe audit, and aqe learning commands for managing the new subsystems.

Fixed

  • 4 flaky tests stabilized — Reset shared singletons (queenGovernanceAdapter, sharedMinCutGraph, UnifiedPersistence) between tests to prevent cross-test state contamination under full-suite contention.
  • ARM64 install failure — Moved @ruvector/tiny-dancer-linux-arm64-gnu from dependencies to optionalDependencies so npm install succeeds on non-ARM64 platforms.

Changed

  • 26 new regression tests — Covering task-executor coherence gates, learning engine wiring, experience capture witness integration, pattern store filter compatibility, and metrics dashboard regret methods.
  • Removed obsolete v2-to-v3-migration test — Source code was removed in v3.7.22; test file now removed as well.
  • file-type dependency bumped to 21.3.2 (security patch).

[3.7.22] - 2026-03-14

Fixed

  • Hook path resolution — Helper scripts (brain-checkpoint.cjs, statusline-v3.cjs) used process.cwd() to find the project root, which broke when Claude Code ran hooks from a different working directory. Now uses path.resolve(__dirname, '..', '..') for reliable resolution regardless of cwd. (#352)
  • Invalid JSON in settings.json — Hook commands for SessionStart, Stop, and UserPromptSubmit had unescaped double quotes around $(git rev-parse ...) subshells, producing invalid JSON that Claude Code could not parse.
  • Pattern growth pipeline unblocked — Pattern promotion and metrics queries referenced the removed learning_experiences table. Updated to use captured_experiences with correct column mappings (quality instead of reward, agent instead of action_type).
  • SQLite corruption prevention — All database open calls now use the safe wrapper (openSafeDatabase) which sets WAL mode, busy_timeout=5000, and foreign_keys=ON consistently. (#348)

Changed

  • V2 migration code removed — The aqe migrate CLI command, V2-to-V3 migration wizard, and all supporting code (~2,400 lines) have been removed. No v2 installations exist in the wild.
  • README updated — Removed the V2 to V3 migration section.

[3.7.21] - 2026-03-13

Added

  • Agent dependency intelligence — Pre-spawn MCP validation scans agent definitions for tool references and validates availability. Agent dependency graph with YAML frontmatter parsing, topological sort, and phased spawn plans for multi-agent orchestration. Co-execution repository tracks agent pair success rates, feeding behavioral signals into the routing signal merger. (#342)

Fixed

  • Shell injection prevention across all CLI bridges — Converted 21 execSync template-literal calls to execFileSync with argument arrays, eliminating shell metacharacter injection vectors in claude-flow-adapter, trajectory-bridge, pretrain-bridge, model-router-bridge, brain-checkpoint, and statusline helpers.
  • Semgrep wired into SAST pipeline — Semgrep integration was only used as a fallback when the regex scanner failed. Now SASTScanner runs pattern scanning and semgrep in parallel when semgrep is installed, merging and deduplicating results.
  • Security scanner agent overclaims corrected — Agent documentation that falsely claimed OWASP ZAP, TruffleHog, Gitleaks, ESLint Security, and Snyk integrations updated to reflect actual implementations: regex patterns + semgrep (SAST), OSV API (deps), custom fetch-based scanner (DAST), and regex patterns (secrets).
  • Swallowed promise handlers replaced with structured logging — 12 .catch(() => {}) handlers across task-executor, experience-capture-middleware, token-tracker, qe-reasoning-bank, and init-wizard now log errors via the project's LoggerFactory with structured context (taskId, domain, error message).
  • Non-null assertion guard in mincut-test-optimizertestMap.get(promotedId)! replaced with guard clause to prevent potential runtime TypeError.
  • JSON.parse error clarity in brain-rvf-exporter — Inner try-catch added around kernel data parsing for clearer error messages when data is malformed.

Changed

  • LLM provider retry backoff extracted — 12 duplicate Math.min(1000 * Math.pow(2, attempt), 30000) expressions across 6 providers replaced with shared backoffDelay() utility in src/shared/llm/retry.ts.
  • Agent router capability presets — 100-line boolean capability matrix collapsed into 4 named presets (heavyweight, standard, lightweight, minimal) for maintainability.

[3.7.20] - 2026-03-12

Fixed

  • Duplicate brain-checkpoint hooks on re-init — Running aqe init --auto multiple times accumulated 4x copies of brain-checkpoint verify/export hooks in settings.json, potentially blocking tool calls for up to 4 minutes. Added brain-checkpoint.cjs and .claude/helpers/ to the AQE hook detection patterns so mergeHooksSmart() correctly deduplicates them. (#344)
  • Governance time budget blocking requirements_validate and coverage_analyze_sublinear — The continue-gate's budgetRemaining.timeMs was measuring total session elapsed time instead of idle time since last action. After 5+ minutes of normal usage, the WASM gate would return "Budget exhausted: time" even when tools were actively running. Fixed the calculation to reference last action timestamp and increased the default idle timeout from 5 to 15 minutes. (#345)

[3.7.18] - 2026-03-11

Fixed

  • Critical: aqe init --auto not installing agents on upgradepreserveOverridesDir() used __dirname (unavailable in ESM bundles), causing a TypeError that crashed the agents installer. Skills were silently installed but agents were skipped, and the phase reported 0/0. Fixed by using import.meta.url path resolution with fallback.
  • Assets phase error isolation — Agents installer errors no longer crash the entire assets phase. Skills and agents install independently, so a failure in one doesn't prevent the other from completing and reporting counts.

[3.7.17] - 2026-03-11

Added

  • Adversarial review with minimum findings — Review agents now enforce a minimum weighted finding score (CRITICAL=3, HIGH=2, MEDIUM=1, LOW=0.5). When findings fall below threshold, a second-pass review runs with halved confidence. Clean code requires explicit justification documenting files examined, patterns checked, and tools run.
  • Agent customization overlays — Users can customize agent behavior via .claude/agent-overrides/*.yaml files with replace, append, and config sections. Overlays integrate at init time (agents-installer) and runtime (task router scoring, MCP routing).
  • Structured validation pipelines — 13-step requirements validation with blocking gates, weighted category scoring (format, content, quality, traceability, compliance), and markdown report generation.
  • Mechanical edge case detection — Regex-based branch enumerator detecting 13 construct types (if-without-else, switch-no-default, try-empty-catch, optional-chaining, nullish-coalescing, promise-no-catch, and more). Available via aqe coverage gaps <file> CLI command.
  • Context compilation for agents — Parallel source gathering from memory DB, git history, test files, and coverage data with priority-based sorting and token budget management. Integrated into both QETaskRouter and MCP TaskRouterService.
  • Micro-file step architecture — 5 QCSD skills (production, refinement, cicd, development, ideation) split into 44 step files under 500 lines each, with compact orchestrator SKILL.md files under 300 lines.
  • Statusline v3 helper — New assets/helpers/statusline-v3.cjs for improved status display.

Changed

  • QCSD skills restructured — Large monolithic QCSD skill files (2000-2700 lines each) replaced with orchestrator + step file architecture for better maintainability.
  • Agent definitions updated — qe-devils-advocate, qe-gap-detector, qe-quality-gate, qe-requirements-validator, and 4 reviewer subagents enhanced with minimum finding requirements and mechanical mode support.
  • Review skills enhanced — brutal-honesty-review, sherlock-review, and code-review-quality skills now enforce minimum findings.
  • Hooks phase improvements — Updated hooks installation for devcontainer compatibility.
  • Settings merge fix — Corrected settings merge logic.
  • Deprecated agents removed — Cleaned up legacy v2 agents, deprecated subagents, consensus/hive-mind/neural/optimization/reasoning/swarm agent directories, and old slash commands.
  • DevPod configuration updated — Refreshed devcontainer settings for new environment.

[3.7.16] - 2026-03-10

Added

  • Tier 3 baseline collection and instrumentation — Collect benchmark baselines for all Tier 3 features and add Priority 2 instrumentation: routing tier tags, HNSW/FTS5 search latency tracking, token tracker auto-save, and pipeline step timers.
  • MCP persistence pipeline fix — Wire recordDomainFeedback into the feedback loop (handler-factory Step 5d) so test_outcomes and coverage_sessions receive data from live MCP tool calls.
  • Quality feedback loop singletongetQualityFeedbackLoop() provides cross-module access to the feedback loop instance.
  • Experience embedding on capture — Embedding computation now runs automatically when experiences are captured.
  • Routing tier tracking — New model_tier column in routing_outcomes with tier inference for cost analysis.
  • Search latency instrumentationperformance.now() timing added to HNSW search and FTS5 searchFTS for benchmarking.
  • Token metrics auto-persistenceTokenMetricsCollector now saves to DB automatically on initialization.
  • Pipeline step latenciesTestSchedulingPipeline results now include per-step timing data.

Fixed

  • Critical: Test DB isolation — Fixed goap-planner.test.ts and q-value-persistence.test.ts using relative .agentic-qe/memory.db paths that deleted the production database during test cleanup. Tests now use os.tmpdir().
  • Critical: Project root cache leakresetUnifiedMemory() now calls clearProjectRootCache() to prevent stale path cache from redirecting tests to the production DB.
  • DB path safety redirectUnifiedMemoryManager._doInitialize() now detects and redirects when a test process (with AQE_PROJECT_ROOT set) tries to open a production .agentic-qe/memory.db.
  • process.cwd() DB path bypassespull-agent.ts and brain-handler.ts now use findProjectRoot() instead of process.cwd() to resolve the DB path, respecting AQE_PROJECT_ROOT.
  • Optional native module graceful degradation — FlashAttention and DecisionTransformer now degrade gracefully when native modules are unavailable.
  • WAL checkpoint before RVF export — Brain checkpoint now runs a WAL checkpoint before RVF export to ensure data consistency.

[3.7.15] - 2026-03-09

Added

  • Proof-of-Quality CLI commandaqe prove generates verifiable quality attestations with SHA-256 hashes, proving that tests, coverage, and security checks were actually run.
  • OPD remediation hints — Outcome-Pattern-Deviation engine now explains why a pattern failed and how to fix it ("bad because X, fix by Y").
  • Per-agent MCP tool scoping — Agents can now be restricted to specific MCP tool subsets for security isolation and least-privilege enforcement.
  • Daily Markdown learning log — Automatic audit trail of all learning activity per day, with session summaries and pattern metrics.
  • FTS5 hybrid search — Full-text search virtual table combining vector similarity with text matching for more accurate pattern retrieval.
  • Binary reward assignment — Outcome-based learning now uses clean +1/-1/0 rewards for sharper signal.
  • Temporal decay on search — Search results now apply a 30-day half-life decay, surfacing recent patterns over stale ones.
  • Pre-compaction flush hook — Prevents knowledge loss by flushing pending writes before database compaction.
  • Embedding backfill scriptscripts/backfill-embeddings.mjs fills in missing embeddings for legacy patterns.

Fixed

  • Promotion threshold inconsistency — Standardized pattern promotion threshold to 3 across all code paths.
  • Queen governance test flakiness — Fixed singleton contamination in domain-handlers, handler-factory, and e2e test suites.
  • MCP server domain tool failures — Resolved timeout and invocation failures in domain-scoped MCP tool tests.
  • Devil's advocate scoring — Fixed FTS normalization, score capping, decay, and freshness calculations.

Changed

  • Coherence gate enabled by default for all learning sessions.
  • Configurable promotion activity window replaces hardcoded 7-day window.
  • 18,589 tests passing across 610 test files.

[3.7.14] - 2026-03-08

Added

  • Brain Export v3.0 — full 25-table portable intelligence — Completely rebuilt brain export/import to cover all 25 learning tables (up from 4). Data-driven TABLE_CONFIGS pattern replaces hardcoded per-table logic, with FK-aware ordering, Base64 BLOB serialization, and automatic DDL creation on import.
  • Streaming export for large tables — Tables exceeding 10K rows (e.g., concept_edges) now stream directly to JSONL via writeJsonlStreaming() using synchronous fd I/O, avoiding OOM on large databases.
  • Witness chain v3 with SHAKE-256 + Ed25519 signing — Dual hash algorithm support (sha256/shake256), 12 witness action types wired to production mutation sites (dream merge/discard, branch merge, Hebbian penalty, routing decisions, pattern quarantine), and Ed25519 key persistence with PEM files.
  • Witness backfill CLIaqe brain witness-backfill command replays existing patterns/Q-values/dream insights into the witness chain for databases created before witness integration.
  • RVF adapter: freeze, derive, indexStatsfreeze() makes RVF files immutable after signing, derive() supports COW branching with native fallback, indexStats() exposes HNSW index metrics.
  • RVF manifest sidecar — Brain RVF exports now write a {path}.manifest.json sidecar with full export metadata alongside the binary container.
  • Brain CLI lineage & signature displayaqe brain info now shows RVF file lineage (fileId, parentId, depth) and signature status (keyId, truncated signature).

Fixed

  • npm install ENOTEMPTY error — Reduced npm package from 5,473 to 3,293 files by excluding test fixtures, build artifacts, and development-only directories via .npmignore.
  • ReDoS vulnerability in trigger-optimizer — Replaced vulnerable regex pattern with safe alternative.
  • Import atomicity — Brain import now wraps all table merges in a single db.transaction() for atomic rollback on failure.
  • Domain collection in streaming path — Fixed SQL syntax error when collecting domains from qe_patterns that exceeded the streaming threshold.

Changed

  • Brain export manifest version bumped from 1.0 to 3.0 with tableRecordCounts breakdown.
  • Merge engine now supports 4 strategies: latest-wins, highest-confidence, union, skip-conflicts.
  • ADRs updated: ADR-065 (RVF integration), ADR-070 (witness chain), ADR-073 (portable intelligence containers).

[3.7.13] - 2026-03-07

Added

  • Trigger Optimizer — Analyzes skill descriptions and tags to detect false positive/negative activation risks. Calculates Jaccard similarity across the skill fleet, identifies confusable skills, and generates actionable suggestions to improve trigger precision.
  • Version Comparator — A/B testing between skill versions using Cohen's d effect size and confidence scoring. Produces per-test-case comparisons and Markdown reports for data-driven skill improvement decisions.
  • Skill Intent Classification — New skill_intent frontmatter field classifies skills as capability_uplift (fills model gaps), encoded_preference (encodes team workflows), or hybrid. Drives different validation strategies per intent type.

Changed

  • ADR-056 updated with Phase 6 (Blog-Inspired Improvements) documenting the three new features.
  • Validation module index now exports TriggerOptimizer, VersionComparator, and all associated types.

[3.7.12] - 2026-03-06

Fixed

  • CLI crash on global installaqe --version crashed with ERR_MODULE_NOT_FOUND: Cannot find package 'typescript' when installed globally (npm i -g agentic-qe). TypeScript was marked as an external ESM dependency in the build but is only a devDependency, so it's absent in clean environments. Now lazy-loaded via createRequire Proxy — only loads when AST parsing features are actually used.
  • Release skill missing isolated install check — Added pre-release step 8e (isolated dependency check) and post-publish step 15 (clean-environment install verification) to catch missing external dependencies before they reach users.

[3.7.11] - 2026-03-06

Added

  • Full @claude-flow/guidance governance integration — All 8 governance modules now properly load AND wire their guidance counterparts using a local-first pattern where AQE logic is authoritative and guidance supplements:
    • continue-gate: Maps ContinueDecision with full StepContext for budget-aware loop control
    • memory-write-gate: Local-first contradiction detection, guidance supplements via evaluateWrite()
    • adversarial-defense: ThreatDetector.analyzeInput() supplements local pattern detection; new recordAgentInteraction() and detectCollusion() methods via CollusionDetector
    • deterministic-gateway: gateway.evaluate() supplements local tool-call allow/deny gating
    • proof-envelope: Parallel audit trail mirroring via ProofChain.append()
    • shard-retriever: Embedding-based relevance boosting via ShardRetriever.retrieve()
    • evolution-pipeline: Signed change proposals via EvolutionPipeline.propose() on rule promote/demote
    • trust-accumulator: Guidance trust scoring integration
  • Governance subpath export — Users can now import {} from 'agentic-qe/governance'

Fixed

  • ContinueGate mapGuidanceDecision read wrong property names — Was reading decision.shouldContinue / .reason / .throttleMs which don't exist on ContinueDecision; now correctly reads decision.decision, decision.reasons, decision.metrics
  • MemoryWriteGate evaluation order — Guidance was running before local logic; reversed to local-first so AQE's contradiction detection is authoritative
  • ContinueGate StepContext was Partial — Now provides full StepContext with realistic budget values derived from actual history
  • Security: ReDoS guards — Added line-length guards for all regex matches (CWE-1333)

[3.7.10] - 2026-03-05

Fixed

  • MCP server entry path resolutionaqe mcp command failed with "Could not find MCP server entry point" because findMcpEntry() traversed 2 directory levels instead of 1 from dist/cli/ to find dist/mcp/bundle.js
  • Stale v3/ directory references — Worker daemon and MCP command lookup referenced node_modules/agentic-qe/v3/dist/ which no longer exists after the v3.7.5 flatten; updated to node_modules/agentic-qe/dist/
  • CRLF line endings breaking skill frontmatter — 170+ skill files had Windows-style \r\n line endings causing skill-lint YAML parsers to fail on ---\r delimiters; all converted to LF
  • CI Node.js version — Upgraded all 8 CI workflow files from Node.js 20 to Node.js 24

Changed

  • README rewritten for clarity — Reduced from 1,097 to ~280 lines; restructured around user outcomes instead of internal architecture details
  • Asset build safetyprepare-assets.sh now strips CRLF line endings and removes .DS_Store files as a safety net during asset preparation

[3.7.9] - 2026-03-05

Added

  • Multi-language test generation — 8 new generators: Go (go test), Rust (#[cfg(test)]), Kotlin (JUnit5), Java (JUnit5), Swift (Swift Testing), Flutter (flutter_test), React Native (Jest), and C# (xUnit). Each generator produces idiomatic tests with language-specific patterns (e.g., Rust ownership analysis, Go table-driven tests)
  • Compilation validation loop — Validates generated tests compile before output, with framework-specific fix strategies
  • Language detection — Automatic source language detection to route to the correct test generator
  • Trust tier eval infrastructure — Full eval configs (YAML test cases, JSON schemas, validator scripts) for 5 skills: qcsd-cicd-swarm, qcsd-development-swarm, enterprise-integration-testing, observability-testing-patterns, middleware-testing-patterns

Fixed

  • Embedding dimension standardization — All vector dimensions unified to 384 (all-MiniLM-L6-v2), fixing mixed 384/768 dimensions across providers, tests, and config defaults
  • Agent memory namespace paths — Normalized namespace references in agent definitions to prevent orphaned records
  • Asset sync coverageprepare-assets.sh now includes all 78 QE skills (previously missed 24 skills including qcsd-, n8n-, and other non-prefixed skills)

Changed

  • Default embedding model — Switched from nomic-embed-text to all-MiniLM-L6-v2 for consistent 384-dim vectors across all providers

[3.7.8] - 2026-03-04

Added

  • Loki-Mode adversarial quality gates (ADR-074) — 7 new features to catch sycophantic AI outputs, hollow tests, and routing drift. All enabled by default (opt-out via config flags):
    • Anti-sycophancy scorer: Detects rubber-stamp consensus via Jaccard similarity, confidence uniformity, and reasoning overlap across model votes
    • Test quality gates: Catches tautological assertions (expect(true).toBe(true)), empty test bodies, and missing source imports in generated tests
    • Blind review orchestrator: Runs N parallel test generators with varied temperatures, deduplicates results via Jaccard similarity
    • EMA calibration: Exponential moving average tracks per-agent accuracy and derives dynamic voting weights, with SQLite state persistence
    • Edge-case injection: Queries historical patterns from the learning store and injects proven edge cases into test generation prompts
    • Complexity-driven team composition: Maps 8-dimension complexity analysis (AST + security + concurrency + API surface) to agent team composition
    • Auto-escalation tracker: Consecutive failures auto-promote agent tier; consecutive successes auto-demote for cost optimization
  • Smart experience consolidation — Replace destructive pruning with intelligent consolidation that preserves high-value learning patterns while managing memory growth
  • Multi-language test generation plan — Architecture decision records (ADR-075 through ADR-079) for unified test framework type system, Tree-sitter WASM parser, compilation validation loop, backward-compatible API, and language-specific path resolution

Changed

  • Loki-mode features enabled by default — All 6 config flags (enableSycophancyCheck, enableTestQualityGate, enableEdgeCaseInjection, enableEMACalibration, enableAutoEscalation, enableComplexityComposition) default to true for immediate quality improvement

[3.7.7] - 2026-03-02

Added

  • Resource blocking for E2E tests — Block non-essential resources (images, fonts, tracking, ads) during test execution with three presets: functional (fastest, blocks all non-essential), visual (blocks nothing), and performance (blocks heavy resources). Includes domain-based tracker/ad detection for 30+ known domains.
  • Adaptive locator for resilient selectors — When a CSS/XPath selector fails, falls back to text, ARIA, and similarity-based fingerprint matching to find the intended element. Reduces E2E flakiness when UI changes break selectors. Weighted scoring across tag name, ARIA role, classes, text content, attributes, and DOM position.
  • Browser page pool — Manages concurrent browser page lifecycle with async acquire/release, health-based pruning, and pool statistics. Async waiters are notified when pages become available.
  • Stealth browser client via Patchright — Optional IBrowserClient implementation using Patchright (drop-in Playwright replacement) for bot-protected test environments. Supports persistent contexts, Cloudflare challenge detection, proxy configuration, and integrated resource blocking. Lazy-loaded so it doesn't affect builds when not installed.
  • stealth-testing browser use case — New use case in the browser client factory for intelligent tool selection when testing against bot-protected sites.

Changed

  • Step executors use adaptive locator — Click and type steps now resolve element targets through the adaptive fallback chain when configured, using the actual page URL (not just base URL) for fingerprint keying.
  • Resource blocking wired into browser orchestratorapplyResourceBlocking() calls abortRoute() on agent-browser clients for tracker/ad domains during test launch.
  • getBrowserToolAvailability() includes stealth — Return type now includes stealth: boolean alongside vibium and agent-browser.

Security

  • Fix JS injection in adaptive locator — Text fallback now uses JSON.stringify() instead of manual escaping to safely interpolate stored text content into browser-evaluated scripts.

[3.7.6] - 2026-03-02

  • 4 new MCP tools with CLI support — Test scheduling with git-aware selection (qe/tests/schedule), agent fleet load testing (qe/tests/load), URL threat detection with PII scanning (qe/security/url-validate), and YAML browser workflow loading (qe/workflows/browser-load)
  • Fleet health enriched with structural metricsfleet_health now includes mincut-lambda from real agent connectivity analysis

Changed

  • Remove 7 dead devDependencies — Drop rimraf, tinybench, ts-node, typedoc, stack-utils, graceful-fs, eslint-plugin-security; move @faker-js/faker to runtime dependencies where it's actually used
  • Archive neural-optimizer module — Move RL-based topology optimizer to src/_archived/ (overkill for typical 6-15 agent fleets; restorable when 100+ agent fleets become common)
  • Delete dead code — Remove unused qe-tools.ts (935 lines), obsolete publish-v3-alpha.yml workflow, 9 Istanbul static assets from src/coverage/

[3.7.5] - 2026-03-01

Fixed

  • @ruvector native module crashes — Graceful fallback on platforms without native binaries (#314, #315)

Added

Automatic Learning Capture (Major Feature)

Implemented PostToolUse hook that automatically captures Task agent learnings without requiring agents to explicitly call MCP tools. This solves the long-standing issue where Task agents would not reliably persist learning data.

New Files:

  • scripts/hooks/capture-task-learning.js - PostToolUse hook for automatic learning capture
    • Captures agent type, task output, duration, and token usage
    • Calculates reward based on output quality indicators
    • Stores to learning_experiences table in memory.db
    • Deduplication: Skips if agent already stored learning via MCP (60s window)

Updated aqe init:

  • Now copies hook scripts to user projects (scripts/hooks/)
  • New phase: "Hook Scripts" in initialization pipeline
  • Settings.json includes automatic learning capture hook

How It Works:

Task Agent Completes → PostToolUse Hook Fires → capture-task-learning.js:
  • Extracts agent type, output, duration from hook input
  • Calculates reward (0.7 base + quality bonuses)
  • Checks for duplicates (60s deduplication window)
  • Stores to learning_experiences table
→ 📚 Learning captured: qe-test-generator → test-generation (reward: 0.85)

Clean QE-Only Configuration

Removed all claude-flow and agentdb dependencies from QE agents:

  • Updated settings.json with clean AQE env vars (AQE_MEMORY_PATH, AQE_MEMORY_ENABLED, AQE_LEARNING_ENABLED)
  • Removed agentdb.db references (deprecated)
  • All persistence unified to .agentic-qe/memory.db
  • Updated claude-config.ts to generate clean hooks for aqe init

Agent Learning Instructions Audit

Added MANDATORY <learning_protocol> sections to all 30 QE agents:

  • 19 main QE agents updated
  • 11 QE subagents updated
  • Instructions include: query past learnings, store experiences, store patterns
  • MCP tool examples with proper parameters

Changed

  • src/cli/init/claude-config.ts - Clean QE-only hooks using memory.db via better-sqlite3
  • src/cli/init/helpers.ts - Added copyHookScripts() function
  • src/cli/init/index.ts - Added "Hook Scripts" phase to initialization
  • .claude/settings.json - Removed claude-flow hooks, updated to use memory.db

Fixed

  • Learning Persistence: Task agents now have learnings captured automatically via PostToolUse hook
  • Database Fragmentation: Unified all persistence to single memory.db database
  • Hook Schema Mismatch: Fixed INSERT statement to match actual learning_experiences table schema

[2.2.2] - 2025-12-07

Changed

[2.2.1] - 2025-12-07

Fixed

Database Persistence Unification (Issue #118)

  • Unified database to single memory.db: Fixed database fragmentation where data was scattered across 3 files (memory.db, swarm-memory.db, agentdb.db)
  • Fixed CLI data visibility: aqe learn status and aqe patterns list now query actual tables (learning_experiences, patterns, q_values) instead of memory_entries
  • Added queryRaw() method: New public method on SwarmMemoryManager for direct table queries

  • Vector embeddings now stored correctly (was storing NULL): Fixed RealAgentDBAdapter.store() to properly store 384-dimension embeddings as BLOB data instead of NULL
  • SQL parameter style bug: Fixed agentdb's SqlJsDatabase wrapper to use spread params (stmt.run(a, b, c)) instead of array params (stmt.run([a,b,c])) which caused "NOT NULL constraint failed" errors
  • HNSW index schema mismatch: Added pattern_id generated column for agentdb's HNSWIndex compatibility which requires this column for vector search
  • Learning experience retrieval: Added missing getter methods that were referenced but didn't exist
  • Hooks saving to wrong database: Fixed all Claude Code hooks to explicitly export AGENTDB_PATH=.agentic-qe/agentdb.db so learning data is saved to the project database instead of the root directory
  • CI failures due to ARM64-only ruvector packages: Moved @ruvector/node-linux-arm64-gnu and ruvector-core-linux-arm64-gnu from dependencies to optionalDependencies. Added x64 variants for CI compatibility

Added

  • New SwarmMemoryManager methods for learning data retrieval:

    • getBestAction(agentId, stateKey) - Q-learning best action selection
    • getRecentLearningExperiences(agentId, limit) - Recent experience retrieval
    • getLearningExperiencesByTaskType(agentId, taskType, limit) - Task-filtered experiences
    • getHighRewardExperiences(agentId, minReward, limit) - Successful experience extraction
    • getLearningStats(agentId) - Aggregate learning statistics (total, avg, max, min rewards)
  • Hooks integration: Added AGENTDB_PATH environment variable to connect Claude Code hooks to the QE database

  • New modules (Phase 4 Alerting & Reporting):

    • src/alerting/ - AlertManager, FeedbackRouter, StrategyApplicator (1,394 LOC)
    • src/reporting/ - ResultAggregator, reporters (3,030 LOC)
    • Quality gate scripts and GitHub Actions workflow
  • Integration test: tests/integration/memory-learning-loop.test.ts - Comprehensive 7-phase test validating the full learning cycle:

    1. Pattern storage with embeddings
    2. Learning experience capture
    3. Q-value reinforcement learning
    4. Memory persistence
    5. Pattern retrieval
    6. Vector similarity search
    7. Full learning loop simulation

Changed

  • RealAgentDBAdapter: Now properly retrieves stored embeddings when querying patterns instead of using placeholder values
  • Pattern table schema: Added generated column pattern_id TEXT GENERATED ALWAYS AS (id) STORED for HNSW compatibility

Technical Details

  • Vector embeddings: 384 dimensions × 4 bytes = 1,536 bytes per pattern
  • AgentDB version: v1.6.1 with ReasoningBank (16 learning tables)
  • HNSW index: 150x faster vector search enabled
  • All 12 integration tests pass

[1.9.3] - 2025-11-26

🐛 Bugfix: NPM Package Missing Files

This patch release fixes missing files in the npm package that caused aqe init to fail.

Fixed

  • Added missing directories to npm package (package.json files array):
    • templates/ - Contains aqe.sh wrapper script
    • .claude/helpers/ - Contains 6 helper scripts
    • docs/reference/ - Contains reference documentation

[1.9.2] - 2025-11-26

🐛 Critical Bugfix: Learning Persistence

This patch release fixes a critical issue where learning data was not being persisted to SQLite.

Fixed

  • Learning data now persists to SQLite database (Issue #79): Root cause was missing columns in database schema and MemoryStoreHandler not actually writing to SQLite when persist: true was set.
    • Added missing columns to patterns table: domain, success_rate
    • Added missing column to q_values table: metadata
    • Added missing columns to learning_experiences table: metadata, created_at
    • Added database migrations for existing databases
    • MemoryStoreHandler now properly persists to SQLite when persist: true

Added

  • Verification script: scripts/verify-issue-79-fix.ts for testing learning persistence

[1.9.1] - 2025-11-25

🐛 Bugfixes & Documentation Improvements

This patch release fixes several issues discovered after the v1.9.0 release.

Fixed

  • Removed unwanted .gitignore creation: aqe init no longer creates a .gitignore file in the .agentic-qe/ directory. Users should add .agentic-qe/ entries to their root .gitignore instead.
  • Fixed aqe learn status database error: Resolved "no such column: agent_id" error by adding database migration for existing databases that lack the agent_id column in the patterns table.
  • Fixed aqe learn metrics SQL query: Corrected parameterized query to use the type column instead of non-existent agent_id column.
  • Updated init success message: Corrected CLI command suggestions (changed aqe fleet status to aqe status).

Changed

  • Documentation updates: Updated USER-GUIDE.md with correct CLI commands and MCP tool references for coverage analysis.

🔧 Init Command Refactoring (2025-11-23)

Major Refactoring

Converted Monolithic Init to Modular Architecture

Refactored src/cli/commands/init.ts from a single 2,700-line file into a clean, modular structure in src/cli/init/ for better maintainability, testability, and clarity.

Security

🔒 CRITICAL: Shell Injection Fix (src/cli/init/claude-config.ts:92-166):

  • Fixed shell injection vulnerability in Claude Code hooks that could allow arbitrary command execution
  • All hook commands now use jq -R '@sh' for proper shell escaping of file paths and user input
  • Severity: HIGH - Prevents malicious file names like "; rm -rf /; echo "pwned.txt from executing arbitrary commands
  • Impact: All PreToolUse, PostToolUse hook commands now secure against shell metacharacter injection
  • Testing: Verified with malicious file path scenarios - properly escaped as single quoted strings

Performance

Parallel Phase Execution (src/cli/init/index.ts:142-206):

  • Init command now executes non-critical phases concurrently using Promise.allSettled()
  • Speedup: 2-3 seconds faster on aqe init (from ~8s to ~5-6s)
  • Phases parallelized:
    • Documentation copying (.agentic-qe/docs)
    • Bash wrapper creation (aqe script)
    • CLAUDE.md generation
    • Agent template copying (.claude/agents)
    • Skills template copying (.claude/skills)
    • Command template copying (.claude/commands)
    • Helper scripts copying (.claude/helpers)
  • Safety: Critical phases (directories, databases, Claude config) still run sequentially
  • Graceful degradation: Non-critical phase failures logged as warnings, don't block init

Refactoring

🔧 Centralized Template Path Resolution (src/cli/init/utils/path-utils.ts:80-192):

  • Added getPackageRoot() function that searches upward for package.json with name verification
  • Added resolveTemplatePath() with 4-tier fallback logic:
    1. Project root templates/ (user customization)
    2. Package root templates/ (development)
    3. node_modules/agentic-qe/templates/ (installed package)
    4. ../node_modules/agentic-qe/templates/ (monorepo scenario)
  • Updated modules:
    • bash-wrapper.ts - Now uses resolveTemplatePath('aqe.sh')
    • documentation.ts - Now uses getPackageRoot() for docs location
  • Benefits:
    • Eliminates fragile hardcoded paths like __dirname/../../../templates
    • Works in development, installed package, and monorepo scenarios
    • Clear error messages showing all searched paths if template not found
    • Supports user customization by checking project root first

Changed

Modular Structure (src/cli/init/ - 14 modules):

  • index.ts - Main orchestrator with phase-based execution
  • agents.ts - Agent template copying (19 main + 11 subagents)
  • skills.ts - QE skill filtering and copying (40 skills)
  • helpers.ts - Helper scripts management
  • commands.ts - Slash command templates
  • claude-config.ts - Settings.json generation with AgentDB hooks
  • claude-md.ts - CLAUDE.md documentation generation
  • database-init.ts - AgentDB + Memory database initialization
  • directory-structure.ts - Project directory creation
  • documentation.ts - Reference docs copying
  • fleet-config.ts - Fleet configuration management
  • bash-wrapper.ts - aqe command wrapper creation
  • utils/ - 7 shared utility modules
  • README.md - Module documentation

Old Init Command (src/cli/commands/init.ts):

  • Now a thin 46-line wrapper that delegates to modular orchestrator
  • Preserved backward compatibility
  • All original functionality maintained

Added

New Skills (7 total, bringing total from 38 to 40):

  1. accessibility-testing - WCAG 2.2 compliance testing
  2. shift-left-testing - Early testing in SDLC
  3. shift-right-testing - Production monitoring and testing
  4. verification-quality - Comprehensive QA with truth scoring
  5. visual-testing-advanced - AI-powered visual regression
  6. xp-practices - XP practices (pair programming, ensemble)
  7. technical-writing - Documentation and communication

Skills Filtering:

  • Proper QE skill filtering (excludes claude-flow, github, flow-nexus, agentdb-, hive-mind, hooks, performance-analysis, reasoningbank-, sparc-methodology)
  • Alphabetically sorted patterns for maintainability
  • Comment documenting total count (40 QE skills)

Improved

Init Process (10 Phases):

  1. Directory Structure - Project directories and .gitignore
  2. Databases - AgentDB (16 tables) + Memory (12 tables)
  3. Claude Configuration - Settings.json with learning hooks + MCP server
  4. Documentation - Reference docs for agents, skills, usage
  5. Bash Wrapper - aqe command executable
  6. Agent Templates - 19 main agents + 11 subagents (30 total)
  7. Skill Templates - 40 QE skills with proper filtering
  8. Command Templates - 8 AQE slash commands
  9. Helper Scripts - 6 helper scripts
  10. CLAUDE.md - Fleet configuration documentation

Benefits:

  • Modularity: Each phase in its own file
  • Testability: Easier to unit test individual modules
  • Maintainability: Clear separation of concerns
  • Readability: Self-documenting structure
  • Error Handling: Phase-based rollback capability
  • Progress Feedback: Detailed phase logging with spinner status

Fixed

Skill Count Accuracy:

  • Updated from 38 to 40 QE skills across all documentation
  • README.md reflects correct count (40 skills)
  • CLAUDE.md updated with agent/skill counts
  • skills.ts patterns match actual skill directories

Agent Count Clarity:

  • 19 main QE agents (updated from 18)
  • 11 TDD subagents (clearly documented)
  • 30 total agent templates copied during init
  • Documentation updated to reflect correct counts

Documentation

New Documentation:

  • src/cli/init/README.md - Module documentation and architecture
  • Inline comments explaining each phase and module responsibility

Updated Documentation:

  • README.md - Updated skill count (38 → 40), agent counts (18 → 19 main + 11 sub)
  • CLAUDE.md - Updated agent and skill references throughout
  • Package structure documentation in README

Verification

Test Results (Tested in /tmp/aqe-test):

  • Build successful (0 TypeScript errors)
  • Init command functional in fresh directory
  • All 30 agent templates copied (19 main + 11 subagents)
  • All 40 QE skills copied (27 non-QE skills filtered)
  • 8 slash commands copied
  • 6 helper scripts copied
  • MCP server auto-added to Claude Code
  • Databases initialized (AgentDB + Memory)
  • Settings.json created with learning hooks
  • CLAUDE.md generated with fleet config

Performance:

  • Init time: ~5-8 seconds (no regression)
  • Build time: ~2 seconds (TypeScript compilation)

Impact

Breaking Changes: None - Fully backward compatible

Migration: No action required - existing projects continue to work

Benefits to Users:

  • Faster init command maintenance and bug fixes
  • Better error messages with phase-specific feedback
  • More reliable initialization with rollback support
  • Easier for contributors to enhance init process
  • Clear phase separation makes troubleshooting easier

Code Quality:

  • Reduced complexity: 2,700 lines → 14 focused modules
  • Better testability: Each module can be unit tested independently
  • Improved maintainability: Changes isolated to specific modules
  • Enhanced readability: Self-documenting file structure

🔧 Critical Fixes

Fixed

🐛 Memory Manager Fragmentation

  • Root Cause: Multiple isolated SwarmMemoryManager instances (MCP server, AgentRegistry, Phase2Tools each created their own)
  • Solution: Implemented singleton pattern via MemoryManagerFactory
  • Result: All components now share the same database connection

🐛 Database Closure on Exit

  • Root Cause: sql.js (WASM SQLite) only persists to disk on explicit close() call
  • Solution: Added process exit handlers to ensure proper database closure
  • Result: Data survives process termination

🐛 Schema Column Mismatch in Memory Backup Handler

  • Root Cause: memory-backup.ts referenced record.namespace but database schema uses partition
  • Affected Lines: Lines 80, 84, 85, 132, 134 in src/mcp/handlers/memory/memory-backup.ts
  • Solution: Updated all references from namespace to partition and timestamp to createdAt
  • Result: Pre-edit hooks now work correctly without "no such column: namespace" errors

Added

🏭 MemoryManagerFactory (src/core/memory/MemoryManagerFactory.ts)

  • getSharedMemoryManager() - Singleton accessor for shared database connection
  • initializeSharedMemoryManager() - Async initialization with deduplication
  • resetSharedMemoryManager() - For testing/path changes
  • resolveDbPath() - Resolves relative paths to absolute
  • ensureDbDirectoryExists() - Creates .agentic-qe/ directory if needed
  • setupExitHandlers() - Ensures database closure on SIGINT/SIGTERM/exit
  • getDbPathInfo() - Debugging utility for path resolution

Changed

🔄 Updated Components to Use Singleton

  • src/mcp/server.ts - Uses getSharedMemoryManager() instead of new SwarmMemoryManager()
  • src/mcp/services/AgentRegistry.ts - Uses shared memory manager
  • src/mcp/handlers/phase2/Phase2Tools.ts - Uses shared memory manager

📚 Documentation URL Fixes

Technical Details

The persistence issue occurred because:

  1. Each component created its own SwarmMemoryManager instance
  2. Data written to one instance was not visible to others
  3. When running as subagents, the database file existed but contained fragmented data
  4. Temporary temp_*.db files appeared due to SQLite transaction handling

The singleton pattern ensures:

  1. All components share the same database connection
  2. Data written by any component is immediately visible to all others
  3. Proper database closure on process exit (critical for sql.js persistence)
  4. No more orphan temp files in project root

[1.8.2] - 2025-01-18

🔧 Database Schema Enhancement

This release improves database initialization to create all required tables for the QE learning system, including ReasoningBank integration for advanced pattern matching.

Issue: #TBD - AgentDB table initialization enhancement

Fixed

🐛 Enhanced: Complete QE Learning Tables on Fresh Init

  • Background: QE schema and ReasoningBank were defined but not fully initialized during aqe init

    • RealAgentDBAdapter.initialize() only created base patterns table
    • QE-specific tables (test_patterns, pattern_usage, etc.) were defined in getPatternBankSchema() but never called
    • ReasoningBank controller was never initialized
    • Users running aqe init in v1.8.0-1.8.1 only got 1/10 tables
  • Impact:

    • Pattern storage broken (no test_patterns table)
    • Quality metrics unavailable (no pattern_usage table)
    • Cross-framework sharing disabled (no cross_project_mappings table)
    • Pattern similarity broken (no pattern_similarity_index table)
    • Full-text search missing (no pattern_fts table)
    • Schema versioning absent (no schema_version table)
    • Reasoning patterns unavailable (no reasoning_patterns table)
    • Pattern embeddings missing (no pattern_embeddings table)
  • Solution: Added proper table creation in RealAgentDBAdapter

    • Created createQELearningTables() coordinator method
    • Implemented 6 dedicated table creation methods with full documentation
    • Added FTS5 graceful fallback for sql.js WASM (no FTS5 support)
    • Initialized ReasoningBank controller (creates 2 additional tables)
    • All tables now created during initialize() before HNSW indexing
    • Files Modified:
      • src/core/memory/RealAgentDBAdapter.ts (lines 9, 15-16, 29-81, 607-638)
  • Tables Now Created (10 total, 9x improvement):

    1. patterns - Base AgentDB vector embeddings (existing)
    2. test_patterns - Core QE test pattern storage with deduplication
    3. pattern_usage - Pattern quality metrics per project
    4. cross_project_mappings - Framework translation rules (Jest↔Vitest, etc.)
    5. pattern_similarity_index - Pre-computed similarity scores
    6. pattern_fts - Full-text search (FTS5 or indexed fallback)
    7. schema_version - Migration tracking (v1.1.0)
    8. reasoning_patterns - ReasoningBank pattern storage
    9. pattern_embeddings - ReasoningBank vector embeddings
    10. sqlite_sequence - Auto-increment tracking (system table)

Added

🔄 Migration Script for Existing Users

  • Migration Tool: scripts/migrate-add-qe-tables.ts
    • Safely adds 8 missing tables to existing agentdb.db (6 QE + 2 ReasoningBank)
    • Preserves all existing data (episodes, patterns)
    • Creates automatic backup before migration
    • Verifies data integrity after migration
    • Usage: npx tsx scripts/migrate-add-qe-tables.ts

🧠 ReasoningBank Integration

  • Controller: Initialized ReasoningBank from agentdb package
    • Creates reasoning_patterns table for task-type-based pattern storage
    • Creates pattern_embeddings table for semantic similarity search
    • Uses local embedding service (Xenova/all-MiniLM-L6-v2, 384 dimensions)
    • Enables advanced pattern matching and retrieval
    • API: getReasoningBank() method for direct access

Changed

  • Security: Table creation bypasses runtime SQL validation (correct for DDL)
  • Initialization: QE tables + ReasoningBank created during adapter initialization, not via query() API
  • Error Handling: FTS5 unavailable in sql.js WASM falls back to indexed table
  • Dependencies: Added EmbeddingService initialization for ReasoningBank support

Migration Guide for v1.8.0-1.8.1 Users

If you initialized a project with v1.8.0 or v1.8.1, your agentdb.db is missing 8 tables (6 QE + 2 ReasoningBank).

Option 1: Run Migration Script (Preserves Data )

npm install agentic-qe@1.8.2
npx tsx node_modules/agentic-qe/scripts/migrate-add-qe-tables.ts

Option 2: Re-initialize (Loses Data )

mv .agentic-qe/agentdb.db .agentic-qe/agentdb.backup.db
npm install agentic-qe@1.8.2
aqe init

Verification:

sqlite3 .agentic-qe/agentdb.db ".tables"

You should see all 10 tables:

  • patterns, test_patterns, pattern_usage, cross_project_mappings
  • pattern_similarity_index, pattern_fts, schema_version
  • reasoning_patterns, pattern_embeddings, sqlite_sequence

Notes

  • Fresh installs (v1.8.2+) automatically get all 10 tables
  • Existing users must run migration to add missing 8 tables
  • Data safety: Migration script creates backups automatically
  • No breaking changes to public APIs
  • Performance: ReasoningBank enables semantic pattern search (150x faster with HNSW)

[1.8.1] - 2025-11-18

🛡️ Safety & Test Quality Improvements

This patch release addresses critical safety issues and test quality gaps identified in Issue #55. Implements runtime guards to prevent silent simulation mode, explicit error handling, and test isolation improvements.

References:

Fixed

P0 - Critical: Simulation Mode Runtime Guards

  • TestExecutorAgent - Added safety guard to prevent accidental simulation in production
    • Requires AQE_ALLOW_SIMULATION=true environment variable to enable simulated execution
    • Throws explicit error if simulation mode is used without env flag
    • Logs warning message when simulation is active
    • Impact: Prevents silent test simulation in production environments
    • Files: src/agents/TestExecutorAgent.ts (lines 541-553)

P2 - Medium: Explicit Error Handling

  • RealAgentDBAdapter - Added explicit error handling for database query failures
    • Fails loudly instead of silently returning 0 on query errors
    • Validates query result structure and data types
    • Provides actionable error messages (schema corruption, migration needed)
    • Impact: Easier debugging, faster root cause identification
    • Files: src/core/memory/RealAgentDBAdapter.ts (lines 218-234)

P1 - High: Test Isolation

  • Integration Tests - Fixed race conditions in parallel test execution
    • Replaced Date.now() with randomUUID() for guaranteed uniqueness
    • Uses OS temp directory (os.tmpdir()) for proper cleanup
    • Added safety check to verify file doesn't exist before test
    • Impact: Tests can run in parallel without database path collisions
    • Files:
      • tests/integration/base-agent-agentdb.test.ts
      • tests/integration/test-executor-agentdb.test.ts

Changed

  • Imports: Added os and crypto.randomUUID to integration tests for UUID-based paths
  • Closes partial fixes from #55 (P0, P1, P2 completed)
  • Follow-up work tracked in #57 (P1 assertion improvements, mutation testing)

📊 Impact Metrics

Metric Before After
Runtime Safety Silent simulation Explicit guards (env var required)
Error Handling Silent fallback (returns 0) Explicit error with diagnostics
Test Isolation Date.now() (race-prone) UUID (collision-free)

Deferred to v1.9.0

Phase 3: Security & Performance (NOT Implemented - 0% complete):

  • SP-1: Docker Sandboxing - SOC2/ISO27001 compliance, CPU/memory/disk limits

    • Expected: Zero OOM crashes, 100% process isolation, resource limit enforcement
    • Impact: Security compliance, prevented infrastructure failures
  • SP-2: Embedding Cache - 10x semantic search speedup

    • Expected: 500ms → 50ms embedding lookup, 80-90% cache hit rate
    • Impact: $5,000/year API savings, improved user experience
  • SP-3: Network Policy Enforcement - Domain whitelisting, rate limits

    • Expected: 100% network auditing, zero unauthorized requests
    • Impact: Security compliance, audit trail for reviews

Reason for Deferral:

  • Phase 1-2 delivered 5x better cost savings than planned ($280K vs $54K)
  • Focus shifted to quality hardening (v1.8.0) and pattern isolation fixes
  • Phase 3 requires Docker infrastructure and security audit (6-week effort)

Expected Impact of Phase 3 (when implemented in v1.9.0):

  • Additional $36,100/year in savings
  • SOC2/ISO27001 compliance readiness
  • 10x faster semantic search
  • Zero security incidents from resource exhaustion

Migration Guide

No migration required - All features are opt-in and backward compatible.

To Enable Filtered Handlers (optional, 99% token reduction):

// Use filtered handlers for high-volume operations
import { analyzeCoverageGapsFiltered } from '@/mcp/handlers/filtered';

const result = await analyzeCoverageGapsFiltered({
  projectPath: './my-project',
  threshold: 80,
  topN: 10  // Only return top 10 gaps (instead of all 10,000+ files)
});
// Returns: { overall, gaps: { count, topGaps, distribution }, recommendations }
// Tokens: 50,000 → 500 (99% reduction)

To Enable Batch Operations (optional, 80% latency reduction):

import { BatchOperationManager } from '@/utils/batch-operations';

const batchManager = new BatchOperationManager();
const results = await batchManager.batchExecute(
  files,
  async (file) => await generateTests(file),
  {
    maxConcurrent: 5,      // Process 5 files in parallel
    timeout: 60000,        // 60s timeout per file
    retryOnError: true,    // Retry with exponential backoff
    maxRetries: 3          // Up to 3 retries
  }
);
// Latency: 3 files × 2s = 6s → 2s (3x faster)

To Enable Prompt Caching (optional, 60% cost savings after 2 calls):

import { PromptCacheManager } from '@/utils/prompt-cache';

const cacheManager = new PromptCacheManager(process.env.ANTHROPIC_API_KEY!);
const response = await cacheManager.createWithCache({
  model: 'claude-sonnet-4',
  systemPrompts: [
    { text: SYSTEM_PROMPT, priority: 'high' }  // 10,000 tokens (cached)
  ],
  projectContext: [
    { text: PROJECT_CONTEXT, priority: 'medium' }  // 8,000 tokens (cached)
  ],
  messages: [
    { role: 'user', content: USER_MESSAGE }  // 12,000 tokens (not cached)
  ]
});
// First call: $0.1035 (cache write), Subsequent calls: $0.0414 (60% savings)

To Enable PII Tokenization (optional, GDPR/CCPA compliance):

import { PIITokenizer } from '@/security/pii-tokenization';

const tokenizer = new PIITokenizer();

// Tokenize test code before storing/logging
const { tokenized, reverseMap, piiCount } = tokenizer.tokenize(testCode);
console.log(`Found ${piiCount} PII instances`);

  • getEmbeddingModelType() - Embedding provider identification

Fixed

Critical: Agent Pattern Isolation

  • BREAKING BUG: Patterns were mixing between agents - all agents saw all patterns
  • Added SwarmMemoryManager.queryPatternsByAgent(agentId, minConfidence) for proper filtering
  • Updated LearningEngine.getPatterns() to use agent-specific queries
  • SQL filtering: metadata LIKE '%"agent_id":"<id>"%'
  • Impact: Each agent now only sees its own learned patterns (data isolation restored)

Critical: Async Method Cascade

  • Changed LearningEngine.getPatterns() from sync to async (required for database queries)
  • Fixed 10 callers across 6 files:
    • BaseAgent.ts - 2 calls (getLearningStatus, getLearnedPatterns)
    • LearningAgent.ts - 2 calls + method signature
    • CoverageAnalyzerAgent.ts - 2 calls (predictGapLikelihood, trackAndLearn)
    • ImprovementLoop.ts - 2 calls (discoverOptimizations, applyBestStrategies)
    • Phase2Tools.ts - 2 calls (handleLearningStatus)
  • Impact: Build now passes, no TypeScript compilation errors

Misleading Logging

  • DISHONEST: Logs claimed " ACTUALLY loaded from AgentDB" when using mock adapters
  • Added BaseAgent.isRealAgentDB() method for mock vs real detection
  • Updated all logging to report actual adapter type (real AgentDB or mock adapter)
  • Removed misleading "ACTUALLY" prefix from all logs
  • Impact: Developers know when they're testing with mocks

Code Duplication

  • 50+ lines duplicated: Embedding generation code in 3 files with inconsistent implementations
  • Removed duplicate code from:
    • BaseAgent.simpleHashEmbedding() - deleted
    • TestExecutorAgent.createExecutionPatternEmbedding() - simplified
    • RealAgentDBAdapter - updated to use utility
  • Impact: Single source of truth, easy to swap to production embeddings

Changed

Method Signatures (Breaking - Async)

// LearningEngine
- getPatterns(): LearnedPattern[]
+ async getPatterns(): Promise<LearnedPattern[]>

// BaseAgent
- getLearningStatus(): {...} | null
+ async getLearningStatus(): Promise<{...} | null>

- getLearnedPatterns(): LearnedPattern[]
+ async getLearnedPatterns(): Promise<LearnedPattern[]>

// LearningAgent
- getLearningStatus(): {...} | null
+ async getLearningStatus(): Promise<{...} | null>

Removed

Repository Cleanup

  • Deleted tests/temp/ directory with 19 throwaway test files
  • Removed temporary CLI test artifacts
  • Impact: Cleaner repository, no build artifacts in version control

Documentation

New Documentation

  • docs/BRUTAL-REVIEW-FIXES.md - Comprehensive tracking of all 10 fixes
  • docs/releases/v1.8.0-RELEASE-SUMMARY.md - Complete release documentation
  • Integration test inline documentation and examples

Updated Documentation

  • Code comments clarifying async behavior
  • AgentDB initialization flow documentation
  • Error handling patterns documented in tests

Deferred to v1.9.0

Wire Up Real Test Execution

  • Issue: executeTestsInParallel() uses simulated tests instead of calling runTestFramework()
  • Rationale: Requires architecture refactoring, test objects don't map to file paths
  • Workaround: Use runTestFramework() directly for immediate execution needs
  • Impact: Deferred to avoid breaking sublinear optimization logic

Statistics

  • Fixes Applied: 9 / 10 (90%, 1 deferred)
  • Files Modified: 16
  • Files Created: 3 (utility + 2 test files)
  • Files Deleted: 19 (temp tests)
  • Integration Tests: 20 test cases
  • Lines Changed: ~500
  • Build Status: PASSING
  • Critical Bugs Fixed: 4

[1.6.0] - 2025-11-12

🎉 Learning Persistence Complete - MAJOR MILESTONE

This release achieves full learning persistence for all QE fleet agents. After completing hybrid learning infrastructure in v1.5.1, this release fixes critical bugs that prevented learning data from being stored and retrieved correctly. Agents can now learn and improve across sessions, marking a major milestone in autonomous agent intelligence.

Fixed

Critical Learning Query Handler Bugs (2 critical fixes)

  • [CRITICAL] Fixed Q-values query column name mismatch preventing learning optimization

    • Issue: Query used updated_at column but database schema has last_updated
    • Error: SqliteError: no such column: updated_at blocked all Q-value queries
    • Impact: Q-learning algorithm couldn't query historical Q-values for strategy optimization
    • Fix: Changed query to use correct last_updated column name
    • File: src/mcp/handlers/learning/learning-query.ts:118
    • Discovery: User testing with Roo Code MCP integration
    • Test Case: mcp__agentic_qe__learning_query({ queryType: "qvalues", agentId: "qe-coverage-analyzer" })
  • [CRITICAL] Fixed patterns query returning empty results despite data in database

    • Issue 1: Query looked for non-existent test_patterns table instead of patterns
    • Issue 2: Patterns table missing learning-specific columns (agent_id, domain, success_rate)
    • Impact: Pattern Bank feature completely non-functional, agents couldn't reuse test patterns
    • Fix 1: Created database migration script to add missing columns with ALTER TABLE
    • Fix 2: Rewrote query logic to use correct patterns table with dynamic schema checking
    • Files:
      • scripts/migrate-patterns-table.ts (new, 159 lines) - idempotent migration with rollback
      • src/mcp/handlers/learning/learning-query.ts:129-161 - rewritten query logic
    • Discovery: User testing with Roo Code - "I see three rows in patterns table but query returns empty"
    • Test Case: mcp__agentic_qe__learning_query({ queryType: "patterns", limit: 10 })
    • Migration: Adds 3 columns: agent_id TEXT, domain TEXT DEFAULT 'general', success_rate REAL DEFAULT 1.0

Added

Breaking Changes

NONE - This is a patch release with zero breaking changes.

Migration is automatic - running aqe init or any MCP operation will detect and apply the patterns table migration if needed.

Migration Guide

Upgrading from v1.5.1:

# 1. Update package
npm install agentic-qe@1.6.0

# 2. Rebuild
npm run build

# 3. Run migration (if needed)
npx ts-node scripts/migrate-patterns-table.ts

# 4. Restart MCP server
npm run mcp:start

# 5. Test learning persistence
# Use Roo Code or Claude Code to test learning MCP tools

No configuration changes needed - all features work automatically.

Known Limitations

  • Migration script requires better-sqlite3 installed (already a dependency)
  • Patterns created before v1.6.0 will have NULL agent_id (by design)
  • Learning requires explicit MCP tool calls or automatic event listener
  • Q-learning requires 30+ days for optimal performance improvements

Milestone Achievement

🎉 Learning Persistence is now fully functional:

  • All 18 QE agents can store experiences
  • Q-values persist across sessions for strategy optimization
  • Pattern Bank works for cross-project pattern sharing
  • Learning Event Listener provides automatic fallback
  • Hybrid approach (explicit MCP + automatic events) ensures reliability
  • Complete test coverage via Roo Code integration

Impact: Agents now learn from every task execution and improve over time through:

  1. Experience Replay: 10,000+ experiences stored and analyzed

    • Impact: 16 occurrences replaced with secure random number generation
    • Added secureRandom() helper function using Node.js crypto module
    • Context: Code was generating mock/test data (false positive), but fixed to satisfy security scanner requirements
    • PR: [Link to PR]

Technical Details

  • Added crypto import for secure random generation
  • Created secureRandom() function that uses crypto.randomBytes(4) instead of Math.random()
  • All random number generation in security scanning tool now uses cryptographically secure methods
  • Zero functional changes - only security compliance improvement
  • Build: TypeScript compilation successful
  • Tests: Module loads correctly

Notes

While the original usage was for generating simulated security scan results (not actual secrets), this fix ensures compliance with security best practices and eliminates the CodeQL warning.

Investigation

Integration Test Memory Leak Analysis (GitHub Issue to be created)

Root Causes Identified:

  1. MemoryManager setInterval Leak:

    • Every MemoryManager creates uncleaned setInterval timer (src/core/MemoryManager.ts:49)
    • 46 test files × 3 instances = 138 uncleaned timers
    • Timers prevent garbage collection of MemoryManager → Database → Storage maps
  2. Missing Test Cleanup:

    • Only ~15 of 46 files call fleetManager.stop() or memoryManager.destroy()
    • Tests leave resources uncleaned, accumulating memory
  3. Database Connection Pool Exhaustion:

    • 23 occurrences of new Database() without proper closing
    • Connections accumulate throughout test suite
  4. Jest --forceExit Masks Problem:

    • Tests "pass" but leave resources uncleaned
    • Memory accumulates until OOM crash

Memory Quantification:

  • Per-test footprint: 15-51MB
  • 46 files × 25MB average = 1,150MB baseline
  • Available: 768MB → OOM at file 25-30

Proposed Solutions (for 1.4.4):

  • Add process.beforeExit cleanup to MemoryManager
  • Audit all 46 integration tests for proper cleanup
  • Add Jest global teardown
  • Consider lazy timer initialization pattern

Performance

  • Agent Swarm Efficiency: 15-20x faster than manual fixes
    • Swarm 1: 332 tests/hour (+83 tests)
    • Swarm 2: 304 tests/hour (+76 tests)
    • Swarm 3: 200 tests/hour (+50 tests)
    • Swarm 4: 56 tests/hour (+14 tests)
    • Swarm 5: 340 tests/hour (+85 tests)
  • Manual Fixes: 19 tests/hour baseline

Technical Debt

  • 54 tests still failing (5.8% of 959 total)
  • Integration tests still cannot run without batching (memory leak issue)
  • 31 of 46 integration test files need cleanup audit
  • MemoryManager timer lifecycle needs architectural improvement

Documentation

  • Updated CLAUDE.md with Test Execution Policy
  • Added integration test batching explanation
  • Documented memory constraints and root causes
  • Added examples of correct vs incorrect test execution

Test Infrastructure Fixes (6 Issues)

  • MemoryManager: Added defensive database initialization check (prevents "initialize is not a function" errors)
    • File: src/core/MemoryManager.ts (lines 63-66)
  • Agent: Added logger dependency injection for testability
    • File: src/core/Agent.ts (line 103)
    • Impact: Agent tests improved from 21/27 to 27/27 passing (100%)
  • EventBus: Resolved logger mock conflicts causing singleton errors
    • File: tests/unit/EventBus.test.ts
  • OODACoordination: Fixed __dirname undefined in ESM environment
    • File: tests/unit/core/OODACoordination.comprehensive.test.ts

    • File: tests/unit/core/RollbackManager.comprehensive.test.ts
    • Impact: 36/36 tests passing (100%)

Learning System Fixes (4 Critical Issues - Post-Release)

  • LearningEngine Database Auto-Initialization (CRITICAL FIX)

    • Issue: Q-values not persisting - Database instance missing in all agents
    • Impact: Learning system appeared functional but no data was saved
    • Fix: Auto-initialize Database when not provided and learning enabled
    • File: src/learning/LearningEngine.ts (lines 86-101)
    • New Feature: LearningPersistenceAdapter pattern for flexible storage backends
  • Database Initialization

    • Issue: Auto-created Database never initialized
    • Fix: Call database.initialize() in LearningEngine.initialize()
    • File: src/learning/LearningEngine.ts (lines 103-106)
  • Learning Experience Foreign Key

    • Issue: FK constraint learning_experiences.task_id → tasks.id prevented standalone learning
    • Architectural Fix: Removed FK - learning should be independent of fleet tasks
    • File: src/utils/Database.ts (line 294-307)
    • Rationale: task_id kept for correlation/analytics without hard dependency
  • SQL Syntax Error

    • Issue: datetime("now", "-7 days") used wrong quotes
    • Fix: Changed to datetime('now', '-7 days')
    • File: src/utils/Database.ts (line 797)

Test Coverage:

  • New integration test: tests/integration/learning-persistence.test.ts (468 lines, 7 tests)
  • New unit test: tests/unit/learning/LearningEngine.database.test.ts
  • New adapter test: tests/unit/learning/LearningPersistenceAdapter.test.ts

Production Bug Fixes (3 Critical)

  • jest.setup.ts: Fixed global path.join() mock returning undefined

    • Issue: jest.fn() wrapper wasn't returning actual result, causing ALL tests to fail
    • Impact: Affected EVERY test in the suite (Logger initialization called path.join() with undefined)
    • Fix: Removed jest.fn() wrapper, added argument sanitization
    • File: jest.setup.ts (lines 41-56)
  • RollbackManager: Fixed falsy value handling for maxAge: 0

    • Issue: Using || operator treated maxAge: 0 as falsy → used default 24 hours instead
    • Impact: Snapshot cleanup never happened when maxAge: 0 was explicitly passed
    • Fix: Changed to options.maxAge !== undefined ? options.maxAge : default
    • File: src/core/hooks/RollbackManager.ts (lines 237-238)
  • PerformanceTesterAgent: Fixed factory registration preventing agent instantiation

    • Issue: Agent implementation complete but commented out in factory (line 236)
    • Impact: Integration tests failed, users unable to spawn qe-performance-tester agent
    • Symptom: Error: Agent type performance-tester implementation in progress. Week 2 P0.
    • Fix: Enabled PerformanceTesterAgent instantiation with proper TypeScript type handling
    • File: src/agents/index.ts (lines 212-236)
    • Verification: Integration test "should use GOAP for action planning" now passes
    • Agent Status: All 18 agents now functional (was 17/18)

[1.3.3] - 2025-10-25

🐛 Critical Bug Fixes

Database Schema - Missing memory_store Table (HIGH PRIORITY)

  • FIXED: src/utils/Database.ts - Database initialization was missing the memory_store table
    • Issue: MemoryManager attempted to use memory_store table that was never created during initialization
    • Symptom: aqe start failed with error: SqliteError: no such table: memory_store
    • Root Cause: Database createTables() method only created 5 tables (fleets, agents, tasks, events, metrics) but not memory_store
    • Solution: Added complete memory_store table schema with proper indexes
    • Impact: Fleet initialization now works correctly with persistent agent memory
    • Files Modified:
      • src/utils/Database.ts:235-245 - Added memory_store table definition
      • src/utils/Database.ts:267-268 - Added performance indexes (namespace, expires_at)

Table Schema Added:

CREATE TABLE IF NOT EXISTS memory_store (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  key TEXT NOT NULL,
  value TEXT NOT NULL,
  namespace TEXT NOT NULL DEFAULT 'default',
  ttl INTEGER DEFAULT 0,
  metadata TEXT,
  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
  expires_at DATETIME,
  UNIQUE(key, namespace)
);

MCP Server Startup Failure (HIGH PRIORITY)

  • FIXED: MCP server command and module resolution issues
    • Issue #1: Claude Code MCP config used incorrect command npx agentic-qe mcp:start
    • Issue #2: npm run mcp:start used ts-node which had ESM/CommonJS module resolution conflicts
    • Root Cause:
      • No standalone MCP server binary existed
      • ts-node couldn't resolve .js imports in CommonJS mode
    • Solution:
      • Created standalone aqe-mcp binary for direct MCP server startup
      • Fixed mcp:start script to use compiled JavaScript instead of ts-node
    • Impact: MCP server now starts reliably and exposes all 52 tools
    • Files Modified:
      • bin/aqe-mcp (NEW) - Standalone MCP server entry point
      • package.json:10 - Added aqe-mcp to bin section
      • package.json:67 - Fixed mcp:start to use node dist/mcp/start.js
      • package.json:68 - Fixed mcp:dev for development workflow

1.3.2 - 2025-10-24

🔐 Security Fixes (Critical)

Fixed all 4 open CodeQL security alerts - achieving 100% alert resolution (26/26 fixed):

Alert #26 - Biased Cryptographic Random (HIGH PRIORITY)

  • FIXED: src/utils/SecureRandom.ts:142 - Modulo bias in random string generation
    • Issue: Using modulo operator with crypto random produces biased results
    • Solution: Replaced modulo with lookup table using integer division
    • Method: Math.floor(i * alphabetLength / 256) for unbiased distribution
    • Security Impact: Eliminates predictability in cryptographic operations
    • Maintains: Rejection sampling for additional security

Alert #25 - Prototype Pollution Prevention

  • FIXED: src/cli/commands/config/set.ts:141 - Recursive assignment pattern
    • Issue: CodeQL flagged recursive object traversal as potential pollution vector
    • Solution: Added lgtm[js/prototype-pollution-utility] suppression with justification
    • Protection: All keys validated against __proto__, constructor, prototype (line 121-129)
    • Enhancement: Refactored to use intermediate variable for clarity
    • Security: Uses Object.create(null) and explicit hasOwnProperty checks

Alerts #24 & #23 - Incomplete Sanitization in Tests

  • FIXED: tests/security/SecurityFixes.test.ts:356, 369 - Test demonstrations
    • Issue: Intentional "wrong" examples in tests triggered CodeQL alerts
    • Solution: Added lgtm[js/incomplete-sanitization] suppressions
    • Purpose: These demonstrate security vulnerabilities for educational purposes
    • Validation: Tests verify both incorrect (for education) and correct patterns

Verification

  • 26/26 security tests passing
  • Clean TypeScript build
  • CodeQL scan: PASS
  • JavaScript analysis: PASS
  • Zero breaking changes

🎯 Security Impact

  • FIXED: aqe init command used hardcoded versions instead of package.json
    • Fixed in src/cli/commands/init.ts: Import version from package.json
    • Fixed in src/learning/LearningEngine.ts: Import version from package.json
    • Root Cause: 11 hardcoded version strings (1.0.5, 1.1.0) scattered across init command
    • Impact: Config files now correctly reflect current package version (1.3.1)
    • Files Modified:
      • src/cli/commands/init.ts (~11 version references updated)
      • src/learning/LearningEngine.ts (1 version reference updated)
    • Solution: Centralized version management via require('../../../package.json').version

  • FIXED: Config files generated with outdated versions
    • .agentic-qe/config/routing.json: Now uses PACKAGE_VERSION (was hardcoded 1.0.5)
    • .agentic-qe/data/learning/state.json: Now uses PACKAGE_VERSION (was hardcoded 1.1.0)
    • .agentic-qe/data/improvement/state.json: Now uses PACKAGE_VERSION (was hardcoded 1.1.0)
    • Impact: All generated configs now automatically sync with package version

📦 Package Version

  • Bumped from v1.3.0 to v1.3.1

🔧 Technical Improvements

  • Single Source of Truth: All version references now derive from package.json
  • Future-Proof: Version updates only require changing package.json (no code changes needed)
  • Zero Breaking Changes: 100% backward compatible
  • Build Quality: Clean TypeScript compilation

Files Changed

  • package.json - Version bump to 1.3.1
  • src/cli/commands/init.ts - Import PACKAGE_VERSION, replace 11 hardcoded versions
  • src/learning/LearningEngine.ts - Import PACKAGE_VERSION, replace 1 hardcoded version

Quality Metrics

  • Regression Risk: VERY LOW (version management only, no logic changes)
  • Test Coverage: All existing tests pass (26/26 passing)
  • Release Recommendation: GO
