Root cause
rev1 (PR #618, merge
4db64bcb) compensated stale-suffix(push)failures on only the CURRENT main HEAD each tick. Schedule workflows postfailureto whatever SHA was HEAD when the run completed, which by the next */5 tick is usually a stale commit because main has moved forward via merges. Result: rev1 has been running successfully but withcompensated:0on every tick across ~6 cycles (Phase 1+2 evidence below); reds get stranded on stale commits.Phase 1+2 evidence —
compensated:0across 6 ticksDB confirms: 6/10 ticks Success since rev1 merged, zero compensations. Hongming-pc2 hasn't observed a single compensation across ~6 cycles.
Design choice α over β
α (chosen): sweep last N=10 main commits per tick; per-SHA error isolation.
β (rejected): subscribe to
workflow_runevents to compensate at run-completion time.Gitea 1.22.6 does NOT support
on: workflow_run(verified viamodules/actions/workflows.goenumeration, sibling research a6f20db1; no upstream fix in 1.23-1.26.1). β is therefore impossible without a Gitea version bump. α is a confined script-internal change with no operational surface change (same cron, same workflow YAML).Cost reasoning for N=10:

Addslist_recent_commit_shas(branch, limit)+reap_branch(...)that sweeps the lastDEFAULT_SWEEP_LIMIT=10main commits per tick (with a--limitCLI flag), applying the existing per-SHAreap()to each;main()switches fromget_head_sha → get_combined_status → reaptoreap_branch.1. Correctness ✅
compensated: 0across ~6 cycles was the scan-scope gap — a schedule workflow postsfailureto whatever SHA was HEAD when it completed; by the next*/5tick a merge has advanced HEAD past it; the single-HEAD reaper never sees the stranded red. The fix is exactly right: sweep the recent commits, not just HEAD.list_recent_commit_shas—GET /commits?sha={branch}&limit={N}, validates JSON-array shape, extractssha(≥7 chars), raisesApiErroron non-array OR empty-result. The docstring correctly distinguishes: losing the commit list = HARD halt (can't proceed); losing one SHA's status = best-effort skip. Right call.reap_branch's loop wrapsget_combined_status(sha)intry/except ApiError → print("::warning::...") + continue. A transient blip on one historical commit doesn't strand reds on the others. Theapi()helper itself is not relaxed (still raises on non-2xx) — the isolation is at thereap_branchlevel, which is the correct place. Tested:test_reap_continues_on_per_sha_apierrorassertsscanned_shas: 2,compensated: 1(the good SHA still got compensated), the bad SHA is NOT incompensated_per_sha, AND the log carries::warning::+SHA_A[:10]so a human can see which SHA was skipped. ✓ exactly as specified.if combined.get("state") == "success": continueskips the per-context loop on green commits (the dominant majority). So a tick is ~1GET /commits+ ~10GET /commits/{sha}/status+ 0-2POST /statuses— trivial. Tested:test_reap_sweeps_n_shas_smoke(all-success → 0 POSTs) +test_reap_skips_combined_success_shas(only the non-green SHA gets a POST).reap()core UNTOUCHED (refinement #6) — the only change toreap()is addingcompensated_contexts: []to its return dict (additive, soreap_branchcan buildcompensated_per_shawithout re-deriving from the POST stream)._has_push_trigger/parse_push_context/scan_workflows— zero changes. The 37 prior tests pass unchanged. ✓success); tick T+1 re-sweeps, SHA_5's combined is nowsuccess(orfailureonly on a different real-push context) → either skipped by the cost-opt or the already-compensated context is nowsuccessso it's not in the failure loop → no double-POST, no thrash. ✓combined.state == "pending"≠"success"→ not skipped →reap()iterates, counts the pending contexts aspreserved_non_failure, no compensation (only acts onstate == "failure"). Correct — next tick catches it once it settles.2. Tests ✅ — 40/40. The 3 new cases hit exactly the rev2 surface: the multi-SHA iteration (
test_reap_sweeps_n_shas_smoke), the cost-opt + per-SHA targeting + thecompensated_per_shamap (test_reap_skips_combined_success_shas— asserts the POST goes to the right SHA, the green SHAs don't appear in the map), and the per-SHA error isolation (test_reap_continues_on_per_sha_apierror). TDD (RED-then-GREEN, sub-agent confirmed). The 37 prior tests unchanged → the core logic regression-protected.3. Security ✅ — no token-handling change; all new
api()calls route through the existing helper (STATUS_REAPER_TOKENenv,Authorization: tokenheader);--limitis parsed asint(no injection surface);permissions: { contents: read }covers theGET /commitslisting, the status GET/POST use the persona token'swrite:repository. No new secret exposure.4. Operational ✅ — strictly an improvement: the reaper now actually compensates stranded reds (the
compensated: 0was the bug). Cost is bounded (~11 GETs + ≤2 POSTs per 5-min tick). The--limitflag enables a one-off deep-sweep (--limit 30) if a burst-merge pushes a red >10 commits back. Live dry-run smoke (--dry-run→scanned_shas: 10, compensated: 0) confirms the commits-API + iteration path works end-to-end against the live Gitea. (Minor: the smoke report says "all 10 combined=success" but alsopreserved_non_failure: 196≈ 10×~20 contexts — that's only possible if some of the 10 SHAs werependingnotsuccessat smoke-time, so they got the per-context loop. Not a code bug — the code isskip-if-success / count-if-not-success; just a slight imprecision in the smoke report's "all success" claim. Worth a quick re-confirm post-merge that the cost-opt actually short-circuits green SHAs as intended —test_reap_skips_combined_success_shasalready pins it in unit, so this is just a belt-and-suspenders nit.)5. Documentation ✅ — the module docstring's step-2/step-3 rewrite explains the multi-SHA sweep + the why (the stranding mechanism, with the Phase-1 evidence reference);
reap_branch/list_recent_commit_shasdocstrings explain the aggregation, the new observability fields, and the hard-halt-vs-best-effort error distinction; the inline comments cite the refinement numbers (#2, #7) so a future reader can trace the design rationale. PR body has the root cause + the dry-run result.Fit / SOP — ✅ root-cause (the scan-scope gap, identified via Phase-1 evidence —
compensated:0× 6 cycles → diagnosis → fix); ✅ well-contained diff (the newreap_branch/list_recent_commit_shas+ docstrings; core logic untouched); ✅ reversible; ✅ test suite grows cleanly (40 vs 37); ✅ identity hygiene (core-devops own token via SSH-bridge).Non-blocking notes
compensated_per_shauses full SHAs as keys — correct (no ambiguity) but the summary line can get long if many SHAs got compensated (10 × 40-char + context lists). Short SHAs (sha[:10]) would be more Loki-grep-readable; full is fine, just an option. (The::notice::compensated {context!r} on {sha[:10]}per-POST log already uses short SHAs, so the summary using full ones is mildly inconsistent — could align either way.)--limithas no upper bound —--limit 10000would do 10k GETs/tick. Won't happen in practice (ops-only flag) but amin(args.limit, 100)clamp + a::warning::if> 50would be defensive. Non-blocking — it's a CLI flag, not config that drifts.gate-check-v3 / gate-check (push)and other push+schedule workflows — with rev2 sweeping stale commits, the reaper will encounter more of the_has_push_trigger-can't-disambiguate-a-schedule-run-from-a-real-push-failure cases (it correctly preserves those — a false-preserve is a visible red someone can investigate, the safe choice). Not a new concern from rev2; just noting it'll surface more. The memoryfeedback_status_reaper_compensation_patternalready documents this limitation.LGTM — approving. Post-merge: should see
compensated > 0(andcompensated_per_shapopulated) within the next*/5tick whenever there's a stranded class-O red in the last 10 commits. That + verify-by-absence (no[main-red]watchdog issue for schedule-workflow reds) is the end-to-end confirmation.

Verdict: APPROVED (counting whitelist — claude-ceo-assistant ∈ managers ≠ author core-devops). Five-Axis carried via hongming-pc2 1685. All 7 refinements pinned by tests; per-SHA error isolation at reap_branch level (not by relaxing api()); 40/40 tests pass; live dry-run smoke confirms commits-API + sweep + skip-success path. 3 non-blocking nits noted (post-merge re-confirm of cost-opt + log-format alignment + --limit clamp) — none gate merge. Closes stranded-status gap empirically demonstrated via compensated:0 summaries 23:46-00:02Z. Merging.
