.gitea/workflows/sop-tier-refire.yml+.gitea/scripts/sop-tier-refire.sh— anissue_comment-event-triggered refire ofsop-tier-checkfor PRs whose approving review landed after the initial tier-check ran. Closes thepull_request_review-no-refire gap on Gitea 1.22.6 (go-gitea/gitea#33700;feedback_pull_request_review_no_refire).Why
The orchestrator currently force-merges approved PRs via the admin path because
sop-tier-check'spull_request_reviewevent subscription is silently dead on 1.22.6. Each force-merge is audited (audit-force-merge.yml→ Loki), but the audit trail keeps growing and the admin-path is a bot-ring fingerprint risk (feedback_github_botring_fingerprint,feedback_never_admin_merge_bypass). This fix eliminates the dependency.How — three security gates in the workflow
if:github.event.issue.pull_request != null— only PRs, not plain issues.comment.author_association∈["MEMBER","OWNER","COLLABORATOR"]— only collaborators+ can flip status (core-security review#1066 ask, internal#292)./refire-tier-check— slash-command-shaped trigger; not just any word in review prose.The workflow does NOT check out PR HEAD; same trust boundary as
sop-tier-check.yml.DRY: re-uses the canonical script
sop-tier-refire.shshells out tosop-tier-check.shwith the same env the original workflow provides. We get the EXACT AND-composition gate (team-membership; internal#189), not a watered-down approving-count check. Then POSTs the result to/statuses/{HEAD_SHA}with contextsop-tier-check / tier-check (pull_request)— the same context branch protection requires, so no admin/protection change needed.Rate-limit
30-second window between status updates per PR head SHA — prevents comment-spam thrash. Pre-fetches
/statuses/{SHA}and comparesupdated_atto now.Tests (T1-T7, 23/23 PASS locally)
state=success, correct context, description names commenter.state=failure.state=failure.if:contains all three security gates; statuses:write permission requested; no PR-HEAD checkout (regression guard).The real script runs against a local-fixture Gitea (
_refire_fixture.py) with a mock tier-check (_mock_tier_check.sh) — the mock sidesteps a known bash 3.2 (macOS) parser bug ondeclare -Ainsop-tier-check.sh. Linux Gitea runners (bash 4/5) execute the real script unchanged in production. The mock is controlled by env (SOP_REFIRE_TIER_CHECK_SCRIPT); production never sets it.Hostile self-review (per
feedback_assert_exact_not_substring)success/failurelabel in refire script (exit 1).Verification (manual)
Manual smoke after merge: open a test PR, approve it, comment
/refire-tier-check, observe thesop-tier-check / tier-check (pull_request)context flip to green.Negative smoke: same PR with no tier label → comment
/refire-tier-check→ status stays/flips to red with "tier-check failed" description.Tier
tier:high — unblocks the approved-PR-backlog drain class. The current bypass (admin force-merge) is a bot-ring fingerprint risk.

While debugging tests I discovered

The script works in production (Linux Gitea runners ship bash 4/5). Not addressing in this PR — it's a dev-ergonomics issue, not a prod bug.

Well-reasoned fix for the Gitea 1.22.6
pull_request_reviewno-refire gap (go-gitea/gitea#33700). Theissue_commentworkaround with author_association gate is the correct pattern.Security model is sound:
pull_requestexistence check, MEMBER/OWNER/COLLABORATOR gate, and/refire-tier-checkslash-command shape — these three layers prevent drive-by abuse.Note on failing Harness Replays / detect-changes: this is a pre-existing bug in
.gitea/workflows/harness-replays.yml'sdetect-changesstep (base SHA unavailable in shallow clone). Being fixed in PR #441. This PR's own changes do not touch harness-replays.yml or any of its guarded paths — the failure is incidental, not caused by #449.SRE note:

Security ✅ — covered by the core-security lens (review above): the collaborator gate is a workflow-level short-circuit; token is
secrets.SOP_TIER_CHECK_TOKEN(withGITHUB_TOKENfallback) — the same org secretsop-tier-check.yml+audit-force-merge.ymlalready use, no new secret; diff is clean of token-shaped strings (only afixture-tokenliteral against the 127.0.0.1 test stub); refire re-uses the AND-composed team-membership gate rather than reimplementing it (aligns withfeedback_least_privilege_via_workflow_env); no PR-HEAD checkout. One non-blocking note (raised by the lens, I endorse it as a follow-up): theSOP_TIER_CHECK_TOKEN || GITHUB_TOKENfallback is a silent-failure trapdoor — if the org secret is ever unset,GITHUB_TOKENlacksread:org→ tier-check fails-closed but with a confusing error. The right fix is a:?SOP_TIER_CHECK_TOKEN unsetguard applied consistently across all three workflows (sop-tier-check.yml,audit-force-merge.yml,sop-tier-refire.yml) — not just refire, which should stay consistent with its siblings. Separate tier:low issue, not a blocker here.4. Operational ✅ — purely additive (5 new files, no existing-file changes). The mechanism is opt-in (only fires on an explicit
/refire-tier-checkcomment) and idempotent (re-evaluates + re-posts the current tier-check state; a spurious trigger is harmless + rate-limited). Eliminates the admin force-merge dependency for the backlog drain → the audit-force-merge trail stops growing and the bot-ring-fingerprint risk (feedback_github_botring_fingerprint/feedback_never_admin_merge_bypass) is closed. Perfeedback_strict_root_only_after_class_a,/refire-tier-checkbecomes the steady-state path; the empty-commit re-trigger and the admin force-merge both retire.5. Documentation ✅ — exemplary. The workflow header has a full SECURITY MODEL block (the 4 properties incl. the no-PR-HEAD-checkout rationale + the "issue_comment loads from base branch" note). The script header documents behavior, required/optional env, and the bash-3.2-workaround rationale inline. PR body has
