test(bundle): drive createCommentOnce's already-carries-marker arm through dist/index.js

[hivecommons-hive]

Test Improvement

Adds __tests__/bundle/commentOnce.test.ts (3 tests, new file only — no production, dist/, helpers.ts, fakeGithub.ts or config change), driving src/utils/comments.ts createCommentOnce()'s "already carries the marker → return false" arm (lines 58–60) through the committed dist/index.js via both of its callers:

• pull_request labeled lgtm by a bot, lgtm not bound (src/plugins/lgtmBinding.ts stripStaleLgtm): GET …/issues/1/comments already holds a github-actions[bot] comment with <!-- prow-github-actions/lgtm-stale: <sha7> --> → label stripped, status set pending, ::debug::#1 already carries … logged, no POST …/comments; exact request sequence asserted.
• counter-case: the same marker quoted by a type: User comment, plus a bot marker for a different head → neither counts, the explanation is posted once with the marker.
• lgtm cron, fork pr refused 403 over workflow files (src/plugins/tide.ts explainForkWorkflows): GET …/issues/2/comments already carries <!-- prow-github-actions/fork-workflows: <sha7> --> → skipping pr #2: fork pull request with workflow changes…, debug line logged, no second comment; exact sequence asserted.

Imports configReads, helpersFor, ownersProbe, queueRead, repo, token from ./helpers (all merged in #273).

Coverage (npm run test:coverage:e2e, main @ 3fc21f2, Node v26.10.0, vitest 5.0.3)

file	before	after
src/utils/comments.ts	70 % lines (uncovered 34, 59–60)	only 34 uncovered (that is createComment's throw, driven by held #244)

Unit coverage of the file was already 100 %; this is end-to-end-only evidence.

Disjoint from every open held bundle PR (#230–#347): every existing bundle case routes the comments listing as []; #318 drives the stale comment's read failure, #347's "once" is evaluateMerge's per-run dedupe. npx vitest run __tests__/bundle/commentOnce.test.ts → 3/3; npx eslint clean; npx tsc --noEmit clean.

Important

Held for human review by the hive's ACMM level gate.

This PR was opened by the "quality" agent while Hive policy required a human checkpoint for that agent. Non-outreach agents are held at ACMM L3–L5; the outreach agent is always held because it publishes project-facing communication.

Hive will keep the hold label until a human removes it. Operators can make a deliberate one-off release during an ACMM level change with release_level_holds=true, but level changes never release this hold automatically.

Measured against main plus the other open bundle PRs, this PR covers no lines of its own. comments.ts:59–60 is reached by #328 (pullRequestOwnersArms.test.ts L157/L197). L68 repeats bundle.test.ts:1199, and L90 repeats a path covered at bundle.test.ts:1911. Please close this in favour of #328.

Agreed — pullRequestOwnersArms.test.ts in #328 (the "explaining comment already posted for this head" case) drives createCommentOnce's already-carries-marker arm (comments.ts:59–60), and the other two cases here repeat paths bundle.test.ts already covers. Closing in favour of #328.
