Why: recording checks in a frozen task card can change the candidate and invalidate current-head CI.
Evidence: SELF fixed-candidate capture regression and all 33 evidence tests passed; actual output and object digests are preserved by make evidence.
Impact: document preparation, external receipts and post-phase import using existing schema 1; no filesystem freeze or trust upgrade is introduced.
Refs: U3; policy/governance.md; .task/feature-merge-queue-policy-draft.md
Why: an existing authorized task should not merge a moving target merely to resume local work, while new task startup and delivery remain strict.
Evidence: SELF red-green recovery and environment regressions; task, recovery, evidence and local-mode write-guard suites passed through make evidence.
Impact: add explicit LOCAL_READY and task-resume, validate worktree/card/baseline and receipt purpose, preserve schema 1 and prevent local receipts from starting or releasing tasks.
Refs: U2; policy/merge-queue.md; .task/feature-merge-queue-policy-draft.md
Why: independent review found shared submodule metadata risk, quoted header leakage, stale JSON receipt blindness and missing abandon coverage.
Evidence: SELF 92 governance regressions pass; the original review receipt and replay output are recorded in the task card.
Impact: preserves external component worktrees, handles both evidence formats and adds targeted failure-path coverage; no product behavior changes.
Refs: .task/feature-governance-reliability.md; .task/reviews/governance-reliability.json
Why: cleanup, component synchronization, receipt recording and credential handling could contradict the documented development boundaries.
Evidence: SELF 75 isolated governance tests and source checks are captured in .task/feature-governance-reliability.md; combination and CI verification follow.
Impact: hardens local task and CI tooling, aligns policy and component documentation, and adds continuous regression tests without changing product behavior.
