Validate is the\nsole `verdict.v2` writer when persistence is requested. It never asks the model\nto reconstruct Plan or Candidate packets.\n\n## Preconditions\n\n- The subject is a nonempty implementation candidate: the manifest lists at\n  least one entry, and `store-verdict` refuses an empty one. Plans, audits,\n  reviews, and other control artifacts are not completion subjects unless the\n  caller explicitly requested document review.\n- The intent source is available as a caller-owned artifact or runtime-owned\n  content-addressed snapshot; its acceptance digest is derived automatically.\n- The subject manifest still matches the subject.\n- Author and validator context IDs are explicit.\n- Freshness is explicitly attested with `source: runtime | caller` and an\n  attester identity.\n\nMissing, colliding, or unattested identities produce `NOT_PROVEN`. This is a\ndeclared trust fact, not cryptographic proof that contexts were isolated.\n\n## Cross-model fresh validator (caller-elected)\n\nA caller may request that the fresh validator run on a different model than\nthe author. Dispatch via the controller-session recipe in\nthe `agent-native` model-dispatch recipe (`codex-exec` and/or `ntm`,\nprobed at runtime). Record author and validator `model_identity` in evidence\nrefs and freshness attestation notes — do not change `verdict.v2` schema. If\nthe requested validator model has no live adapter, disclose the unsatisfied\ndiversity request and proceed same-model; never invoke `claude -p` /\n`claude --print`. Single fresh validator remains the default shape.\n\n## Mutating-check quarantine\n\nBefore running any acceptance-listed command, classify it as read-only or\nsubject-mutating. Regen scripts, sync scripts, formatters, and anything with\n`--force` are subject-mutating until proven otherwise. Never run a\nsubject-mutating check against an uncommitted subject: on 2026-07-15,\n`scripts/test-ci-deterministic-gates.sh` regenerated `skills-codex/` from HEAD\nmid-validation and destroyed the uncommitted subject, forcing `NOT_PROVEN`\n(verdict `b6e759dd...cb6a`); only restoring the subject and revalidating in a\nfresh context produced the PASS (`e9b6cdb8...37b9`). If a mutating check is\ngenuinely required by acceptance, run it against a disposable copy or a\ncommitted subject, never the judged working tree.\n\n## Scope disclosure\n\n`not_checked` has exactly one meaning: **in-scope acceptance surface this\nvalidation did not verify**. PASS asserts that the whole declared acceptance\nsurface was verified, so a PASS carries no `not_checked` entries; the helper\nrefuses one and records a `validate.integrity` finding.\n\nThat rule never pays for deleting an honest caveat, because every kind of scope\nlimit has a home that survives inside a PASS:\n\n| Scope limit | Home | Example |\n|---|---|---|\n| A criterion proven by a bounded check | `criteria[].reason` on that criterion | \"proven by the unit suite; the full integration matrix was not replayed\" |\n| A declared non-goal or out-of-scope area | the intent source's non-goals, optionally restated as an evidence-backed boundary criterion in `criteria` | \"`cli/**` is a declared non-goal; the diff proves it untouched\" |\n| Residual risk or judgment caveat | the caller-facing report | \"the migration path is untested against pre-3.0 stores\" |\n| Acceptance that genuinely went unverified | `not_checked`, and the result is `NOT_PROVEN` rather than PASS | \"criterion 3 needs hardware this context cannot reach\" |\n\nEmptying `not_checked` to obtain PASS is a contract violation, not a\nworkaround. If acceptance really went unverified, the honest result is\n`NOT_PROVEN`. If the entry was never acceptance in the first place, it belongs\nin one of the other homes, where it stays visible in the stored artifact\ninstead of being deleted.\n\n## Helper commands\n\nThe helper ships beside this file. Invoke it through this skill's own\ndirectory rather than a checkout-relative path: `$SKILL_DIR` is the directory\ncontaining this `SKILL.md` — `skills/validate/` in a repository checkout,\n`.agents/skills/validate/` in an installed runtime.\n\n| Command | Required | Optional |\n|---|---|---|\n| `manifest` | `--root <dir>`, `--include <path>` (repeatable, at least one) | `--exclude <path-or-glob>` (repeatable), `--base-manifest <file>`, `--git-metadata-json <json>`, `--output <file>` |\n| `verify-manifest` | `--root <dir>`, `--manifest <file>` | `--base-manifest <file>` |\n| `snapshot-intent` | `--source <file>` (`-` reads stdin) | `--workspace <dir>`, `--intent-dir <dir>` |\n| `digest` | `<json-file>` positional | none |\n| `store-verdict` | `--draft`, `--intent-source`, `--subject-manifest`, `--author-context-id`, `--validator-context-id`, `--freshness-source <runtime\\|caller>`, `--freshness-attester-id`, `--scope-result <PASS\\|FAIL\\|NOT_PROVEN>` | `--workspace <dir>`, `--verdict-dir <dir>` |\n\n```sh\npython3 \"$SKILL_DIR/scripts/validate.py\" manifest \\\n  --root . --include skills/validate --exclude '**/*.log' --output manifest.json\n```\n\n## Workflow\n\n1. Recompute and compare `subject-manifest.v1` with the `manifest` command\n   above (`--root` plus at least one `--include`). The helper uses only\n   filesystem content; Git commit/tree IDs are optional metadata. Derive the\n   manifest at the start of validation and re-derive it at the end; any\n   mismatch between the two is subject mutation and returns `NOT_PROVEN`.\n2. Confirm the intent-source digest has not changed since implementation. If\n   the subject changed or complete changed-path coverage cannot be derived,\n   return `NOT_PROVEN`.\n3. Adjudicate the actual diff, not a declared path list: compare\n   runtime-derived actual changed paths against the intent's scope classes. A\n   proven out-of-scope path returns `FAIL`; incomplete scope evidence returns\n   `NOT_PROVEN`.\n4. Inspect the exact subject and factual evidence. Reported exit codes are\n   claims, not evidence: re-execute the claimed proofs that bear on acceptance\n   (see the freshness rules below for when a digest-bound receipt suffices).\n   If the subject changes a test, gate, fixture, golden, tolerance, suppression,\n   or acceptance source, determine whether the original intent requires that\n   change and whether green came from implemented behavior rather than a\n   weakened oracle. Green obtained by weakening acceptance is `FAIL`, not\n   evidence of completion.\n   Judge every acceptance criterion and record criterion-level results,\n   findings, evidence references, `checked`, and any acceptance surface that\n   went unverified in `not_checked` (see Scope disclosure).\n5. Choose exactly one semantic result: `PASS`, `FAIL`, or `NOT_PROVEN`. Return\n   it with criterion results, findings, evidence references, `checked`,\n   `not_checked`, the acceptance and subject identities, distinct author and\n   validator context IDs, and the freshness attestation. PASS requires distinct\n   identities, explicit freshness, nonempty checked scope, top-level evidence,\n   evidence for every criterion, and an empty `not_checked`; route bounded\n   proofs, declared non-goals, and residual risk to the homes named in Scope\n   disclosure rather than deleting them or downgrading a proven result.\n6. Only when the caller requests machine-readable evidence or a declared\n   downstream consumer requires it, persist canonical `verdict.v2` with the\n   helper's\n   `store-verdict --draft <draft.json> --intent-source <resolved-intent>\n   --subject-manifest <manifest.json> --author-context-id <id>\n   --validator-context-id <id> --freshness-source <runtime|caller>\n   --freshness-attester-id <id> --scope-result <PASS|FAIL|NOT_PROVEN>`. The\n   helper snapshots the exact resolved intent under\n   `<workspace>/.agents/ao/intents/sha256/<digest>.intent`, then computes and\n   injects intent and subject digests plus author, validator, and freshness\n   facts. Identity and changed-path facts come from runtime-derived inputs and\n   receipts, not model transcription. Storage defaults to\n   `<workspace>/.agents/ao/verdicts/sha256/<digest>.json`; callers may provide\n   `verdict_dir`.\n7. Return the semantic result and, when persisted, the artifact path and digest.\n   Stop.\n\nThe digest is SHA-256 over canonical JSON with `artifact_digest` omitted. Writes\nuse a same-directory temporary file, flush, fsync, and atomic rename. Identical\nexisting content is idempotent success; conflicting content is an integrity\nfailure represented by `NOT_PROVEN`.\n\n## Freshness without duplication\n\nFresh validation means independent judgment over the exact subject. It does not\nrequire mechanically replaying every author command. Verify intent identity,\nscope, evidence digests, and every acceptance criterion; independently rerun\nthe risk-critical, uncertain, or insufficiently evidenced checks. A\ndigest-bound deterministic receipt may prove routine facts. Replay an expensive\nfull suite only when acceptance requires that result or the supplied receipt\ncannot establish it.\n\n## Boundary\n\nValidate emits no WARN, confidence, disposition, briefing learning, owner,\nnext action, repair, retry, replan, helper, escalation, tracker, Git, release,\nclosure, or delivery state. Generic provenance may record a verdict later, but\nledger availability cannot change its validity.\n","command":"/bin/zsh -lc \"sed -n '1,240p' /Users/bo/.agents/skills/validate/SKILL.md\"","exit_code":0,"id":"item_1","status":"completed","type":"command_execution"},"type":"item.completed"}
