Why: card_merge only recognized "Merge ... from <branch> into main"
merge commits, so a PR landed as a squash (real case: #457) left its
task card in .task/ forever; task-close reported nothing to close and
precheck showed no debt. Closing required a manual backfill (PR #541).
Evidence: card_merge now returns sha|subject|pr and falls back to a
Gitea API lookup by head ref or label (deleted branches keep the
original name only in label), gated by merge_commit_sha ancestry in
origin/main; precheck [cards] reuses card_merge so both surfaces agree.
Live probe against production Gitea returns 226a4af15791|Reset
per-service runtime state in svc.sh env_config|457 for
feature/svc-pidcheck-leak; stub-server tests cover squash landing,
decoy skip and the not-on-main refusal; full governance suite follows
in-card evidence.
Impact: scripts/task.sh close and precheck detect squash-merged cards
when GITEA_TOKEN is set (merge-commit path unchanged without token);
tests/test_task.py adds two regressions; no protocol change for
existing merge-commit closures beyond the appended pr field.
Refs: card-merge-misses-squash-merges (memory); PR #541 manual closure.
Why: F2 token extraction predates the two-section (HOME/IMC) layout of
~/.secrets/gitea so it concatenated both tokens and always failed; F6
registered a grep BRE alternation that facts-verify unescapes into a
literal pipe, failing re-verification and misaligning precheck's naive
pipe split into a spurious F6 date-format expiry warning, while both
underlying facts still hold.
Evidence: make facts-verify now 6/6 PASS with last_verified refreshed
to 2026-10-14; new regression test for escaped pipes in facts rows;
full governance suite 342 tests OK (18 skipped); precheck [facts] line
reports all facts fresh on the fixed parser.
Impact: policy/facts.md F2 (HOME-section awk extraction) and F6
(negated pipe-free grep); scripts/task.sh precheck neutralizes escaped
pipes the same way facts-verify does; tests/test_task.py covers it.
Refs: precheck WARN 过期事实 F6(日期格式); AGENTS.md 证据与验证门禁.
Why: pipefail treated a recent merged-card match as a failed git log after grep exited early, hiding completed cards from precheck and task-close.
Evidence: A disposable long-history regression failed before the fix and passed after it; make test-governance passed 341 cases. Git history confirms PR #489/#488/#486 merge SHAs.
Impact: Detect merged cards reliably and archive only the three authorized trial cards; four unrelated eligible cards remain untouched.
Refs: Dev merge queue #518; Dev #489, #488, #486
Why: agents need consistent entrypoints and recording defaults to avoid retrying synchronization and CI outside the final delivery window.
Evidence: SELF generated-task-card red-green regression and governance suite recorded through make evidence; pending shared record created as Issue #518.
Impact: rules, task template and capability matrix stay explicit about pending activation, default strict startup, manual coordination and unchanged CI triggers.
Refs: U4; policy/merge-queue.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: repeated task-sync calls changed HEAD and invalidated CI even when main had not advanced.
Evidence: SELF red-green regression and 58 task lifecycle tests recorded through make evidence in the task card.
Impact: sync still fetches and validates components, creates records only for an actual merge, and reports the complete final source SHA.
Refs: U1; policy/merge-queue.md; .task/feature-merge-queue-policy-draft.md
Why: make the agent responsible for merging reviewed PRs without another human merge step.
Evidence: SELF governance and generated-card checks are captured in .task/feature-agent-pr-merge.md; CI remains required on the final PR HEAD.
Impact: update project delivery policy, agent entry points, task metadata and closure guidance; preserve platform protection and scoped authorization.

Why: git receive-pack runs 'gc --auto' in the background after a push;
the fixture's TemporaryDirectory teardown then races the gc writer and
fails with OSError 39 (remote.git not empty) — observed on the PR #285
runner (job 1967). The fixture remote holds no durable value, so auto-gc
is pure flake surface.
Evidence: the failing test passes 5/5 locally after the fix; full
make test-governance green (104 tests).
Impact: test fixture only; no governance-script behavior change.
Refs: Dev CI run 1438 job 1967; same race family as the upload-host
TempDir flake fixed earlier.
Why: preserve project direction across tasks and require grounded next-task recommendations.
Evidence: the generated task-card regression fails before the template update and passes afterward; original SELF receipts are in the task card.
Impact: document the planning entrypoint and extend task records without granting new-task execution rights.
Refs: .task/feature-goal-continuity.md; policy/delivery.md
Why: archived task cards change directory and must retain an unambiguous policy reference.
Evidence: review finding 1, focused red-green proof and 104 passing governance tests are preserved in the task card.
Impact: use a repository-root text reference; record the completed review and its resolved finding.
Refs: .task/feature-iterative-delivery.md; .task/reviews/iterative-delivery.json
Why: main advanced with merged-task-name and legacy evidence guards during this task.
Evidence: SELF 44 lifecycle regressions pass after resolving both hunks; independent review repairs are recorded in the task card.
Impact: retains both task-start protections and the stronger JSON/legacy receipt reader, without rewriting either branch history.
Refs: Dev PR #211 and #212; .task/feature-governance-reliability.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.
