Summary

Widens the finish quarantine from moq-dev/moq#8404 to every publisher, per the maintainer's 2026-11-09 decision (rejected: quarantining each lane separately; leaving only cpp and rust quarantined).

A loaded local just test interop --all (while iterating moq-dev/moq#8366) also failed the finish go cells, plus js -> c and rust-swapped -> js-native-node once; a clean rerun passed. With three publishers failing finish the same way, the suspected cause is the harness's waits under load, not one implementation.

• test/interop/interop.sh: run_finishes records every finish cell as a quarantined skip. The body stays in place behind shellcheck disable directives so removing the quarantine is a deletion.
• quest/m0/test-flakes-2/interop-finish.md: covers every publisher and records js -> c and rust-swapped -> js-native-node (not quarantined), leading with the harness-under-load hypothesis; first step is still a loaded reproduction with logs kept. Epic README entry updated.

ℹ️ Two documentation gaps only — the harness change itself checks out.

Reviewed changes

• finish quarantine widened — run_finishes now records every PUB_LIST × SUB_LIST cell as a quarantined skip and returns, leaving the original orchestration body behind a single # shellcheck disable=SC2317 so removing the quarantine is a deletion.
• Unused helpers annotated — finish_ready and finish_marker gain SC2329 disables since only the unreachable body calls them; shellcheck 0.11.0 is clean on the file apart from the three pre-existing SC1091 infos.
• Follow-up quest widened — the goal, plan, and the epic's Required entry now cover every publisher, and the plan records the unquarantined js -> c and rust-swapped -> js-native-node misses alongside the harness-under-load hypothesis.

ℹ️ test/interop/README.md still presents the finish case as a live lane

The section at test/interop/README.md:112-131 tells readers that just test interop --finish --all runs the case and spells out the pass criteria, with no hint that every cell is now a recorded skip. The README does mark other quarantined cases (line ~558, the replacement case), so one sentence here keeps the interop doc honest about what CI actually covers.

Technical details

# Document the finish quarantine in the interop README

## Affected sites
- test/interop/README.md:112 — "The in-tree matrix also has a `finish` case. `just test interop --finish --all` runs it alone." reads as an active lane.
- test/interop/README.md:558 — existing precedent: "The replacement case is quarantined from the default run on every engine until …" shows how this README marks quarantines.

## Required outcome
- A reader of the interop README learns that the whole `finish` scenario currently records skipped cells, and is pointed at the quest tracking its removal.

## Suggested approach (optional)
- Add a sentence beside the existing `quest/m3/ietf-finish.md` reference at line 130 that names `quest/m0/test-flakes-2/interop-finish.md` as the quarantine record.

The Required entry now covers every publisher, but the provenance paragraph three lines up (quest/m0/test-flakes-2/README.md:252-254) still reads "interop's finish cases with a cpp or rust publisher … They are quarantined until their child fixes them". Since the code now quarantines all five publishers, that decision record understates what the epic is tracking. Widening it to "interop's finish cases with any publisher" (and noting the go failures) keeps the epic consistent with run_finishes.

Walkthrough

The documentation now covers finish cases for every publisher and records observed failures and reproduction details. In run_finishes, the script records non-moq-transport-* publisher/subscriber finish cases as skipped during quarantine, then returns before the existing finish-test loop.

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. 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 3 functions across 1 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

No actionable defects found.

The quarantine covers the same publisher/subscriber cells that planning records, emits explicit skips with the follow-up quest, and returns before opening finish FIFOs or starting finish clients. The existing moq-transport skip reason remains intact. Normal media, wrong-tone, tail, and socket scenarios retain their separate dispatch paths.

The scope matches the recorded decision to quarantine the whole finish scenario. The follow-up appropriately treats a shared harness cause as unconfirmed and calls for a loaded reproduction with retained logs before fixing the cause and restoring coverage. No changes requested.

Limits: GitHub-only static review of all three changed files, relevant result handling, and recent history. No builds, ShellCheck, tests, or load reproduction were run. Skipped finish cells do not verify finish behavior. COMMENT only, not approval.
