Summary

• Quarantines js/net's "a session close right after a datagram track's end keeps the end" with test.skip for every version. Its lite-06 case dropped chore(deps): bump the nix group with 2 updates #8280 from the merge queue, js/net's lite-06 session-close test keeps the end under load #8321 re-enabled it with a Budget.poll mock, and its lite-05 case then failed the merge queue for feat(net)!: finishing a track or group returns a Finished handle #8276 with Session: remote error: 0.
• Plans quest/m0/test-flakes-2/datagram-close-end.md [S] to order the abort after the end by an observed event and remove the skip, and records it in the flake epic.

Under the repository's flaky-test rule: disable now, fix in a quest.

Impact

None: a test and a quest. No public API or wire change.

Walkthrough

The session-close-after-end test changes from an active test to test.skip. The flake tracker records the reported merge-queue failure and lists a follow-up quest. The quest describes investigating event-based ordering for client.abort() after the client observes the end event. It does not describe an implemented test fix.

Merge Risk: Low · up to 4e91b

The quarantine is mergeable with follow-up awareness: lite-07 temporarily loses protection against post-end abort regressions. Restore deterministic coverage in the documented follow-up.

Full details: Title check

Explanation

The title names the main change: the js/net datagram session-close-after-end test is quarantined with test.skip, and a fix is planned in a quest document. The title matches the changeset's test skip and quest doc additions, and it is specific enough for a teammate scanning history.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 1 files. (2 skipped: 2 unsupported.)

Full details: Description check

Explanation

The description states the PR quarantines the js/net datagram session-close-after-end test with test.skip for every version, explains the lite-06 and lite-05 merge-queue failures, and names the plan document and the flake-epic record. It also states the impact is a test and a quest, with no public API or wire change. This is specific and directly tied to the changeset.

Restore deterministic lite-07 post-end abort coverage.

The enabled lite-05/06 test does not cover lite-07’s separate datagram path. With this test skipped, a regression that aborts a track after its end can pass the suite. As a follow-up, order the abort after the client observes the end and assert the result after teardown.

ℹ️ One factual correction inline; the quarantine itself is sound.

Reviewed changes

• Quarantines the flaky test — js/net/src/lite/datagram-tracks.test.ts now registers the datagram session-close-after-end case with test.skip for all three ALPN versions, with a comment pointing at the new quest.
• Adds the quest — quest/m0/test-flakes-2/datagram-close-end.md plans ordering the abort after an end event the client observes, then removing the skip.
• Records it in the epic — the test-flakes-2 README gains a Plan paragraph and a Required child entry.

I verified the skip locally: the filtered run reports 3 skip, 0 fail.

Automated review by review (OpenAI)

Reviewed head 4e91b50. No actionable findings in this quarantine change.

The skip covers the session-close-after-end case for all three ALPN variants without changing production code or the neighboring tests. The linked quest and epic entry track restoring coverage with an observed end event instead of a fixed microtask drain. This intentionally leaves the skipped scenario untested until that follow-up lands; it does not fix the underlying race.

Verification limits: GitHub-only static review of all three changed files and surrounding test setup/cleanup. No test runs or merge-queue reproduction performed.

Reviewed changes

This run reviewed the delta since the prior Pullfrog review (4e91b50..3ce0a4d), which is documentation-only:

• Corrected the #8321 history in the quest — quest/m0/test-flakes-2/datagram-close-end.md now says #8321 re-enabled the test with no fix after finding no repro, and points at its investigation (rules out microtask reordering; names Budget stubbed only after connect resolves and now() in group.ts/cache.ts as the real-time suspects).
• Mirrored the correction in the test comment — js/net/src/lite/datagram-tracks.test.ts now attributes the quarantine to lite-06 on #8280 and lite-05 on #8276 after #8321 re-enabled it, dropping the earlier claim that #8321 added the Budget.poll mock.

I checked both claims against #8321's PR body ("No repro, so no fix", the microtask conclusion, and the Budget/now() suspects), and they match. The earlier inline finding on this history is now addressed; the quarantine and quest plan are otherwise unchanged.
