Align release metadata, capability-scoped support, installation guidance, hook boundaries, maintainer documentation, changelog ownership, and the PR-first release procedure with the stabilized distributions.
Constraint: Canonical and Claude surfaces use 2.2.2 while the Codex manifest retains 2.2.2-codex.0.
Rejected: Maintain two current changelogs | duplicate release authority drifts.
Rejected: Publish before the Windows matrix passes | violates the accepted release state machine.
Confidence: high
Scope-risk: moderate
Directive: Keep generated skill versions sourced from the canonical skill and preserve immutable release tags.
Tested: hooks 228/228; orchestrator 195/195; regression 65/65; maintenance 50/50; transform; shell syntax; link/path sweep; diff check
Not-tested: GitHub Windows runner remains blocked pending explicit approval for a fresh gate attempt
Adds the 14th family command — a layered regression stability gate (orchestrator + git-worktree differential core + debug-style hunter) across 8 dimensions with a tiered HARD/SCORE verdict and the green-to-red classification invariant. Ships scripts/score-regression.sh, tests/test-regression.sh (50 assertions, 10 golden fixtures), 5-surface mirror parity, and 3 plugin manifests. Released as v2.1.4.
