📝 WalkthroughWalkthroughThe production and read-only workflows replace the pinned cleanup action with a repository-owned Go driver. The driver validates configuration and API listings, enumerates runs from a fixed repository-wide snapshot, applies workflow filters and retention rules, and plans deletions before mutation. It reports dry-run results and stops when a deletion is rejected or unconfirmed. Native HTTP tests cover selection, pagination, retries, and deletion failures. Workflow credential checks and documentation are updated for the driver. Severity of issue fixed: Medium 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

The retained orphan-consistency concern in CodeRabbit's review is repaired at 3770f62. Before any mutation, each orphan parent is individually looked up after its run was observed. A valid existing workflow retains its runs; only a complete, unambiguous GitHub Not Found response confirms absence. Unknown or invalid lookup evidence stops the entire plan before any deletion. The new race control reproduced deletion of the protected run before the repair. Native HTTP controls now pass for an appearing workflow, denied lookup, unconfirmed or duplicate-key absence and a wrong identity. They also prove that a later orphan lookup failure prevents deleting an already-selected ordinary run. A healthy confirmed-absence fixture preserves the previous orphan filter/age/minimum policy. The complete suite passes under the race detector. Function documentation now describes the driver's validation and mutation boundaries and the native fixtures' purpose, addressing the reported documentation-coverage warning. Current-head hosted CI and fresh substantive review remain required. |

The native minimal-input run exposed a real concurrency defect: its run history changed between pages, so the cleanup correctly refused to act but could not finish in this busy repository. Commit d790791 freezes every run search at the last complete second before invocation. It splits searches at GitHub's 1,000-result cap into disjoint ranges, including the ambiguous exactly-1,000 case, and refuses overflowing single-second buckets, out-of-range records, inconsistent pages and inaccessible later partitions before mutation. Both new behavior regressions failed before this repair and passed afterward. The full race-enabled suite passed 59 cases; the cleanup projection and 29 README contract cases also passed. The new hosted run must confirm the native caller behavior before promotion. CodeRabbit is currently unavailable on this PR: its authenticated 2026-10-06T01:16:32Z reply reported that included reviews are exhausted, with recovery in 39 minutes (01:55:32Z). There is no current-head CodeRabbit verdict; earlier findings remain accounted for. Advancing to Codex in the ordered review loop without requesting paid overage. |

- Cursor Bugbot: freshly read user/team usage refusal, provider event 2026-10-04T23:36:15Z. Scope is the requesting user/team; recovery requires a user/team administrator to lift the limit. The current lane-health observation continues to report usage exhaustion with no successful review, and direct current-head reads contain no Bugbot check or finding.
Reviewed the current diff, driver, native HTTP conversation tests, workflow permissions/source identity, generated projection and credential controls. Inputs enter through environment bindings; repository names cannot choose another host, redirects cannot forward credentials, and the checkout uses the defining workflow's repository and exact SHA without persisted credentials. PR callers retain their read-only ceiling. The driver requires complete, unambiguous HTTP 200 listings and HTTP 204 deletions; DELETE has no application retry and the lost-response fixture proves a single write. Every selected workflow and orphan-parent read finishes before mutation, and any later read failure prevents all writes.
The native CI failure at the earlier head showed arrivals shifting pagination. Both run endpoints now use the same fixed creation-time cutoff. Capped searches, including exactly 1,000 results, split into disjoint inclusive second ranges; leaf searches require stable totals, unique identities and range membership. Dense one-second buckets and inaccessible later partitions fail closed. The full race-enabled suite passed 59 cases, including a 1,001-run partition, retention across pages, native command defaults/overrides and failed-write exits. Hosted current-head caller checks are still pending and remain a separate promotion gate.
Earlier CodeRabbit orphan-race findings are fixed by parent revalidation and appeared/denied/malformed/wrong-ID controls. Its docstring warning was addressed with function documentation. LanguageTool's capital-H suggestions concern literal .github paths, so changing them would break the paths; those suggestions are refuted. The checkout warning has a disclosed resolution and its thread is resolved. Direct conversation, review-object, thread and Bugbot reads found no new unresolved finding.
Verdict: no P0/P1 findings

Reviewed the full change and the new shared-snapshot delta. All workflow metadata and repository-run pages must be complete before planning. A fixed creation-time cutoff prevents new arrivals from shifting the run pages. Searches at or above 1,000 results are partitioned into disjoint second ranges; inconsistent totals, duplicate/out-of-range identities, denied later partitions and overflowing one-second buckets fail before mutation. Validated runs are grouped by their exact workflow identity, so each selected workflow retains its own newest minimum matching old runs plus recent runs. This removes redundant per-workflow rescans while preserving the filters. Unknown workflow parents require individual confirmed-absence lookups before orphan deletion; newly appearing parents are retained.
The full race-enabled native suite passed 63 cases. The single-snapshot regression failed before the change and passed afterward. The multi-workflow fixture proves independent minimum retention and filename filtering. The existing defaults/overrides, rejected writes, uncertain responses, pagination, orphan races, redirects and cancellation controls remain green.

All three callers retain the read-only ceiling and the generated wrapper matches production.
Direct current-head review, conversation, thread and Bugbot reads contain no new finding, and all three no-gate guards admit this head.

The real-API exercise and hosted caller results remain separate user-evaluation/CI gates. This review authorizes neither promotion nor merge while those gates are pending.
Verdict: no P0/P1 findings
At commit 481d124, the native command completed against the real GitHub API with its normal preview defaults. A local bridge allowed only GETs to this repository's workflow/run endpoints and blocked every mutation method; the command received a synthetic bridge credential, not the live API credential. It completed with 141 reads, zero write attempts and The earlier implementation made 230 reads and reached the same probe's eight-minute deadline before completion. The final implementation reuses one complete run snapshot instead of repeating per-workflow scans. This is a concrete completed user-path exercise, not a claim about production deletion authority or a controlled performance benchmark. Rejected/unknown writes remain covered against the offline HTTP API. The full race-enabled suite passed 63 cases. A two-workflow control failed before shared-snapshot planning and passed after it; separate controls preserve each workflow's minimum retention and filename filter. All 29 credential controls, the full catalogue credential graph, workflow/test wiring and 29 README contract cases passed. Current-head hosted checks remain required before promotion; the earlier local review is stale, and review 5422854418 is the qualifying clean review for this commit. |

Reviewed the fresh-base merge as well. Main repair #509 preserves two PR-only caller admissions outside execution selection; no cleanup driver, wrapper or fixture byte changed in the merge. The selector, trusted-base catalogue-scope controls, complete credential graph and cleanup native suite passed after integration. The previously completed real-API exercise therefore applies to identical enacting bytes; final hosted execution still must bind this new workflow commit before promotion.
Verdict: no P0/P1 findings
Final integration head: 0dd5828, including current main 726fb7e and its #509 CI-admission repair. The merge is signed, and the selector, trusted-base scope controls, complete credential graph and native cleanup suite pass after integration.

Hosted coverage job 112068145995 exposed a harness mismatch: its fixed Go 1.26.6 toolchain tried to build the command inside the nested module that declares Go 1.26.8. The production wrapper actually invokes the source file from outside that module. Commit 60fed6b makes the native command fixture use an isolated workspace and the absolute shipped source path, matching that invocation without changing production's Go 1.26.8 pin or CI's Go policy. The original fixture failed with the same Go 1.26.6 compiler before the change. The complete race-enabled suite passed with both Go 1.26.6 and Go 1.26.8 after the repair. No check is skipped or allowed to fail. The production driver, its module and both wrappers are unchanged.

Evaluated the signed current head d97627d as a command user. The compiled production command ran against a loopback HTTP server that admits only synthetic credentials and literal fixture histories/deletions. Two confirmed deletions were separated by more than one second. A preview printed both proposed deletions, performed no writes and completed without a pacing pause. Sending SIGTERM after the first confirmed deletion interrupted the pause, returned a failing exit and produced no second write or completion claim. No real workflow history was changed. The earlier complete real-API read-only evaluation remains applicable to the unchanged enumeration/retention path; this directly exercises the newly added mutation pacing and cancellation path. The full race-enabled suite, Go 1.26.6 compatibility, README parity, 29 credential/source negative controls, complete credential graph and generated projection parity pass. Final hosted checks and a fresh current-head review remain separate promotion gates. |
Final-head hosted behavior and credential readback for d97627d: CI 37402542001 ran all three cleanup callers successfully. Each checked out b4b4f8a, the merge of this exact source head into reviewed base 726fb7e; each used Go 1.26.8 and the complete generated read-only wrapper.

Final source d97627d has 211 successful checks and no reported test failure. In CI 37402542001, the sole remaining Windows authenticated .NET job passed the actual tests at 02:09:26Z and its source-preservation assertion. It has remained in managed checkout post-job cleanup since 02:09:27Z, with no terminal conclusion after more than 14 minutes. Recording this as a stalled managed-runner job, not a passing complete CI run. Canceling this own exact-source run and retrying the failed/canceled job plus its dependent required-check aggregation at the same source; successful job evidence is preserved. Promotion remains blocked until the restarted job, required reducer and complete current-head checks finish successfully. No source or check is disabled to bypass the stall. |

Reviewed commit: d97627d
- CodeRabbit: the normal current-head request 6008130116, made after CI settled, received an explicit review-rate-limit refusal at 2026-10-06T02:32:21Z. This refusal is scoped to this PR's command; it is not a green review or a global outage. The freshly read edited summary, updated at 02:32:18Z, reports exhausted included OSS reviews and the next included review in 27 minutes, approximately 02:59:18Z when bound to that event. Recovery is quota renewal; the contract explicitly permits immediate local review during this retry window. The reply, summary and request were freshly read, and no serving review remains in flight.
- Codex: the connector's refusal on this PR, submitted at 2026-10-06T01:25:08Z, reports exhausted account code-review usage. The source was freshly read. Recovery requires account quota renewal or maintainer intervention; purchasing usage is not authorized.
- Cursor Bugbot: the requesting-user/team usage-limit refusal, submitted at 2026-10-04T23:36:15Z, was freshly read under the same authenticated requester. The live lane-health result also reports usage exhaustion and no completed Bugbot review. Recovery requires the account/team administrator to lift the limit. This is user/team scoped, not a verdict on this diff.
I reviewed the complete native driver and workflow changes against the current base, then the final pacing, cancellation, fixture and documentation delta. The review covered correctness, deletion safety, credential boundaries, compatibility and actual caller execution. No new actionable finding remains.
Enumeration requires complete, unambiguous HTTP 200 responses, stable totals, unique identities, required fields and bounded pagination. Run enumeration uses one repository snapshot with a fixed creation cutoff. Searches reaching GitHub's 1,000-result ceiling are divided into disjoint second ranges; ambiguous dense ranges fail before mutation. The snapshot is grouped by workflow rather than repeatedly scanning repository history. All enumeration and orphan-parent revalidation completes before writes. A parent appearing after the original workflow listing is retained; an uncertain parent lookup stops planning. This does not claim that GitHub provides a transactional history snapshot.
Mutations require HTTP 204 and are never replayed. Rejection, transport uncertainty and cancellation stop the command with a failing exit. The first write is immediate; each later write waits at least one second after the preceding confirmed write. Cancellation interrupts that wait, while previews have no pacing delay. The compiled-command evaluation measured a 1.002348708-second gap between two confirmed writes, zero writes in preview, and exactly one write when SIGTERM interrupted the pause. Regression cases cover incomplete listings, duplicate identities, capped searches, retention and filters, changed orphan parents, rejected writes and interrupted pacing. The complete race-enabled suite passed with Go 1.26.6 and Go 1.26.8.
Both wrappers check out the reusable workflow's own repository and exact commit using job.workflow_repository and job.workflow_sha, disable persisted checkout credentials and bind caller inputs through environment variables. The existing production permissions remain actions: write and contents: read. The read-only wrapper retains its read-only ceiling and is regenerated from the canonical wrapper. The 29 independent credential/source controls, projection and README behavior checks pass. The executable fixture now uses the same named-source compilation context as the actual reusable workflow; it does not assume the caller workspace is a Go module.
The three hosted All, Specific and Minimal callers completed successfully at this exact head with read-only credentials, Go 1.26.8 and the verified merge of this head with base 726fb7e. They selected 2,834, 2,224 and 2,834 runs respectively without deletion. The required reducer and all 286 checks are settled and successful. Run 37402542001 attempt 2 succeeded after an ordinary targeted rerun of the managed Windows job whose tests had passed but whose checkout post-step stalled; no check was excluded or weakened.
CodeRabbit's previously reported orphan-parent race, missing documentation, write pacing and separator documentation findings are fixed. Its final-head replies confirm the last two fixes. All three review threads are resolved, including the separately documented checkout finding. Empty reply-container reviews and quota replies were not counted as substantive green reviews. The final audit found no unresolved inline or non-thread finding. The release interface and orphan retention policy remain explicitly documented.
Verdict: no P0/P1 findings
Ready to promote and merge d97627d against current main 726fb7e. The final readback has 290 settled, successful or intentionally skipped/neutral checks and CI - Required Checks succeeds. There are zero unresolved threads and no unresolved inline or non-thread findings; the branch is clean against main and no other writer is working on it. The substantive exact-head local review satisfies the review gate. All three external lanes have separately authenticated, freshly read quota refusals; CodeRabbit's current-head refusal includes a retry window. This is the permitted fallback, with no review/check bypass or paid usage. The review-verdict helper confirms GREEN self@d97627d244ef446c84eb65510942620be0eac59f. User evaluation is recorded in the compiled command pacing/cancellation probe and three hosted real-API read-only callers. The race-enabled native suite, credential/source controls and generated-wrapper parity pass. No real run history was deleted during evaluation. The stalled managed Windows post-step has since completed successfully on the ordinary targeted rerun at the same head, and the full CI run succeeds. |

Why
Workflow cleanup can report success after GitHub rejects a deletion. That hides incomplete cleanup and leaves operators unable to trust the result.
What
Make cleanup fail on rejected or unconfirmed deletions and finish reading the history before deleting anything. Protect runs whose workflows appear during cleanup, while preserving preview defaults and ordinary retention behavior. Native tests exercise these failures without live deletion authority.
