Description

Fixes retry-on-race in run_tests_inline_auth.yml (#62): its retry went green, but the PR that lost the race stayed red and blocked, while the Slack alert was suppressed.

What we measured in lu_market (forced races, PRs #849–#851, since closed):

• A dispatched run's check on the PR's head commit does not count toward the PR's required check. Only runs triggered by the PR itself count. After the old retry, PR #849's required run-tests / test-templates stayed FAILURE while the retry run on the same commit was green.
• A re-run of the losing run (Re-run failed jobs) does count, and it reads the current CONFIG_JSON. It refreshed cleanly and the PR's check went to SUCCESS. (be_market's fork assumed re-runs reuse the old secrets; they don't.)

New flow:

1. The losing PR run's retry-on-race dispatches the caller's workflow on the default branch with rerun_run_id=<its own run id>. A run can't re-run itself while still going.
2. In that dispatch run, only the new rerun-losing-run job runs. It waits for the losing run to finish, then runs gh run rerun <id> --failed. Attempt 2 can't retry again, because retry-on-race requires run_attempt == 1.
3. The helper alerts Slack itself if it can't re-run: failed, cancelled, timed out, or the run ended as something other than success/cancelled. A failed re-run alerts from its own attempt.

The helper only re-runs a run that is all of the following:

• a pull_request run
• of the same caller workflow
• from a branch in this repo, not a fork
• under 2 hours old
• still on its first attempt, re-checked after the wait
• still an open PR whose head is the run's commit, checked right before the re-run (a newer commit has its own run; a merged PR is a quiet skip)

Duplicate helpers for the same run are serialised. Dispatching on the default branch also removes the old "branch predates the trigger → 422" case. check-changed-templates, test-templates and the alert job all skip on the helper's dispatch run, and the base_sha dispatch path is removed.

Caller change needed: swap the workflow_dispatch input base_sha for rerun_run_id (README updated). lu_market follows in its own PR. Until it merges, a race in LU dispatches with an input LU's caller doesn't declare yet → 422 → the normal Slack alert fires, the same loud behaviour as no retry at all. be_market (still on its own fork) is unaffected and gets this when it moves to the shared file.

Type of change

• Bug fix
• New feature
• Breaking change

Checklist

• README updated (if needed)
• Version updated (if needed)
• Documentation updated (if needed)

Test plan

• actionlint: no new findings (the 4 shellcheck notices predate this change)
• Helper's parsing and run filter checked in bash against real lu_market runs: a genuine loser is accepted; an attempt-2 run, a dispatch run, a 4.5h-old run and a malformed ID are refused
• /review-pr dry run (correctness, error handling, security). 6 findings, all fixed in b465769; the attempt-number timing gap was raised by all three finders independently
• After the lu_market caller PR merges: force a race again and confirm the loser's PR check turns green via the re-run, with no Slack alert

Walkthrough

The inline-auth workflow dispatches a helper with the losing run ID. The helper validates the target run, waits for completion, and reruns failed jobs when eligible. Helper runs skip the normal alert, template-detection, and test jobs.

Changes

Inline-auth retry flow

Layer / File(s)	Summary
Caller retry dispatch .github/workflows/run_tests_inline_auth.yml, README.md	The caller checks that the pull request head has not moved, then dispatches the workflow on its default branch with the losing run ID as rerun_run_id. The README describes this input and retry flow.
Validate and rerun losing run .github/workflows/run_tests_inline_auth.yml	The helper validates the run ID and target run, waits up to 15 minutes, and reruns failed jobs only if the target is a qualifying first-attempt pull request run that concludes with failure.
Helper-run workflow isolation .github/workflows/run_tests_inline_auth.yml	Helper runs use a separate Slack alert step and skip the normal alert, template detection, and tests. Changed-file comparisons use the PR base SHA or push before SHA, not a dispatched base_sha.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 7d5d8

No new merge-blocking issue was established in the reviewed workflow. Failed retry dispatches still trigger the original alert.

164-165: REACHED_WAIT is set too early. It also does not reach the Slack step as intended.

GITHUB_ENV writes apply to later steps in the same job. The Slack step is a later step, so the flag does reach it. The flag is set after validation and before the run_attempt check. A hand-dispatched helper for an already re-run loser exits 0 and does not alert, so this case is harmless.

I found no defect here. This also resolves the earlier review concern about refused dispatches paging Slack.
