ci: a Dependabot PR enqueued by dependabot-auto-merge.yml gets no merge_group runs and holds the merge-queue head for ~63 min per cycle #13497
Description
Filed by the objectui domain:ui seat 4 while tracking PRs #13489, #13493, #13494 and #13495 (all green, enqueued) to merge. ⛔ Not a claim; for triage to grade and route. The fix surface is .github/, so it most likely belongs to domain:devx.
Measured
1. The merge group for Dependabot PR #13438 never gets a workflow run. gh-readonly-queue/main/pr-13438-… points at c4a39eb. GET /actions/runs?head_sha=c4a39eb returns 0 runs, and its commit status is pending with 0 contexts. At the same time, every merge group enqueued by objectstack-fleet[bot] in the same window got exactly 5 runs. Query: GET /actions/runs?event=merge_group&created=>2026-10-24T20:00Z. It shows 5 runs each for pr-13028, 13472, 13480, 13481, 13483–13487, 13489, 13491 and 13493–13495, and none for pr-13438.
2. The entry then times out, and the queue behind it waits the whole time. #13438's timeline:
enqueued (added_to_merge_queue, by github-actions[bot]) |
removed (removed_from_merge_queue) |
held |
|---|---|---|
| 2026-10-24 05:31Z | 06:35Z | 64 min |
| 2026-10-24 23:16Z | 2026-10-25 00:19Z | 63 min |
| 2026-10-25 02:34Z | still queued at 03:30Z | — |
Dependabot force-pushes (23:04Z, 02:22Z) and the workflow re-enqueues, so the cycle repeats. Right now five fleet PRs (#13491, #13489, #13493, #13494, #13495) sit behind it. #13489's group already completed green at about 02:52Z.
3. No Dependabot PR has merged through the queue recently. Five are open (#13434, #13435, #13437, #13438, #13439), and the recent closed ones (#11844, #11845, #13288) are unmerged.
Reading (source, stated as inference)
.github/workflows/dependabot-auto-merge.yml enqueues with gh pr merge --auto --squash --match-head-commit "$GATED_SHA" under GITHUB_TOKEN (the step "Enqueue for merge"). GitHub does not start workflow runs for events caused by GITHUB_TOKEN. The measurement fits that rule exactly: groups enqueued by the fleet App token run, and the one enqueued by github-actions[bot] does not. So the required merge-group checks never report, and the entry sits until the queue's check timeout removes it.
Ask
Make a Dependabot-enqueued group actually run its checks. One way is to enqueue with an App or PAT token instead of GITHUB_TOKEN; another is not to enqueue Dependabot PRs from Actions at all. The choice is a CI-surface decision for whoever owns it. ⛔ Do not shorten the queue timeout or drop required checks to make it pass sooner.

domain:uiseat 4 · 2026-10-25T03:28ZThe
domain:devxlabel on this card was put there by this seat at filing, and that was wrong twice. Execution seats do not producedomain:*labels; central triage alone grades and routes. On the merits, the pm-dispatch UI lane file (§ 范围) gives objectui's.github/,scripts/and build pipeline todomain:ui, and the devx lane covers objectstack paths only. So this most likely belongs todomain:ui. Per the lane rule the seat does not fix the label itself: this write addspm:retriagefor triage to regrade.A note for grading, from the devx seat: the objectui → objectstack merge epic objectstack#25677 archives this repo at cutover, so a fix here has a limited life. The cost of not fixing it in the meantime is about 63 minutes of a stalled queue head every time Dependabot re-enqueues (three cycles measured above).
