Queue-flake anchor: packages/app-shell/src/views/metadata-admin/PermissionMatrixEditor.servedLabel-26884.test.tsx #27150
Description
packages/app-shell/src/views/metadata-admin/PermissionMatrixEditor.servedLabel-26884.test.tsx has ejected 5 pull requests from the merge
queue within a rolling 24 hours — 1 independent hit once
GitHub's speculative stacking is accounted for. This issue is the single place for
that conversation; it is refreshed by the merge-queue-triage workflow on every
further ejection.

stack column is read out of the queue
branch names: GitHub builds each queued PR on top of the previous entry, so a
build whose BASE chain reaches another victim's queue HEAD (directly, or through
green groups queued between them) contains that victim's tree by construction.
A single deterministic break therefore ejects every PR
behind it, and the raw victim count climbs with QUEUE DEPTH until the owner
lands a fix. Start with the root above; an inherited row is a bystander until shown otherwise.
This issue is a NAME, not a diagnosis. The workflow that files it reads the
failing test file path out of the job logs and counts PRs; it does not
know whether this is a flake, a load/timing cliff, a semantic conflict between
queued PRs, or a real regression, and it does not act on any of those. No test is
skipped, quarantined or re-queued by it, and no PR is labelled by it — weakening
a gate stays a human act.
What to do with it: read one victim PR's triage comment for the failure REASON
line beside the FAIL line (a timeout and an assertion are the same FAIL line and
opposite diagnoses), decide the cause, and close this issue with the fix or with
the reason it is not one.
A later queue build that went green on the same main is a control only if its
affected-only selection ran the failing package; a green group that never selected
it carried the same tree without testing it.
Last refreshed by queue build 40655321196 (PR #27043).
Filed by the merge-queue-triage workflow (#4859, aggregation #10128).

Root cause ·
domain:ui#2·session_01JQwxbXpF772qWJjojJvRXw· 2026-10-28T08:19ZAll the hits so far are one cause: PR #27019's own new test, not load and not the other PRs in the stack.
PermissionMatrixEditor.servedLabel-26884.test.tsxbuilds a fake client (makeClient) with nowithPreviewDrafts. Since #27019 branched,main'sPermissionMatrixEditor.tsxcallsclient.withPreviewDrafts(true)(≈L239 get, ≈L915 list), so the load throws and the header never renders. This is the same break #27095 / PR #27103 fixed for the other fakes. #27027 and #27035 failed only because their speculative builds stacked on #27019.Action: #27019 was removed from the queue and drafted at 08:17Z. Its dev merged
origin/mainand gave the fakewithPreviewDrafts. The seat re-pins and re-readies it once the new head is green. ⛔ Do not re-enqueue #27019 on its old head.objectstack-fleet commentedon Oct 28, 2026
