Queue-flake anchor: src/domains/mcp-object-schema-mask.test.ts

src/domains/mcp-object-schema-mask.test.ts has ejected 2 pull requests from the merge
queue within a rolling 24 hours — 2 independent hits 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.

PR	stack	queue build
#31142	independent	42383103865
#31149	independent	42385456389

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 42385456389 (PR #31149).

Filed by the merge-queue-triage workflow (#4859, aggregation #10128).

Cause read from build 42385456389 (PR #31149's ejection): the failing assertion at mcp-object-schema-mask.test.ts:785 compares wireText(member) with wireText(staff), and the wire text includes the Last-Modified header. The two strings in the log differ only there: Sat, 07 Nov 2026 15:19:24 GMT vs 15:19:23 GMT. Two requests made in sequence straddled a second boundary.

So this is a timing flake in the test, not a projection difference: the body and ETag are equal. A fix is to drop Last-Modified (or every date header) from wireText before comparing, or to freeze the clock for the pair. The test came in with #31104 (ADR-0106 D1).

⛔ Not a claim.

runtime src/domains/mcp-object-schema-mask.test.ts failed on two unrelated PRs, fix(plugin-security): canReadObject, getReadFilter and security/explain answer the delegated business-unit read as the read door does #31142 (15:06Z) and feat(cli): os mcp connect registers your environment's MCP server with Claude Code #31149, as two independent hits with no stacking between them. Both fail a JSON-string Object.is comparison of a served action entry (st_ping, then st_rename), and fix(plugin-security): canReadObject, getReadFilter and security/explain answer the delegated business-unit read as the read door does #31142 passed on its re-run and merged.
Two independent hits on unrelated diffs, which a re-run clears, point to nondeterminism in the test or in the projection it pins (key order, an entry's optional fields), not to either PR. The surface is the one PR fix(rest, runtime)!: the /meta action doors and MCP list_actions serve an action entry as the object door projects it (ADR-0106) #31104 landed this morning (the /meta action doors and MCP list_actions).
Graded p1, domain:server, pm:queue on the anchor itself: two queue ejections in one afternoon is a repeated red (「平台测试清单反复变红，肯定要修啊」). The fix makes the comparison order-insensitive, or makes the projection deterministic if that is the defect, and keeps what the test proves. finding removed.
