Test Improvement

Adds six rows to __tests__/utils/mergeQueue.test.ts, one per non-equivalent mutant of src/utils/mergeQueue.ts that survived the full related suite (60 files / 1166 tests) despite 100 % line and branch coverage. A 23-mutant single-operator probe on main @ 88241f4 (boolean guards, ==/===, regex anchors and flags, each alternative of the classify patterns, >/>=, the position and enqueuer folds) killed 16; these six changed nothing a test asserts, because every existing classify fixture message satisfies two alternatives at once and no login carries github-actions as a suffix:

line	mutant	new row
153	botLoginPattern drop ^	enqueuedByBot › my-github-actions -> false — a human whose login ends in github-actions is not an automation; the gate must not dequeue their entry (tide.ts:362)
168	drop expected head	classifies "expected head did not match" as head_moved
168	drop head oid	classifies "the head OID of the pull request has changed" as head_moved
174	drop required	classifies "Required reviews are missing" as not_ready
174	drop checks	classifies "Checks are still running" as not_ready
177	drop forbidden	classifies "Forbidden" as forbidden

classify's kind drives tide.ts:336's per-kind handling of a refused enqueue, so each alternative is a behaviour, not a wording. The one equivalent survivor — $ after \[bot\] — is deliberately not tested: GitHub logins cannot contain [, so [bot] is only ever a suffix.

Files / functions claimed: __tests__/utils/mergeQueue.test.ts (enqueue › classifies "%s" as %s table, enqueuedByBot table). Test-only; no src/, dist/, docs/ or config change. Disjoint from the open held PRs #510–#528: none touches this file or src/utils/mergeQueue.ts (#518 covers tide.ts through __tests__/plugins/tide*.test.ts; #528's mergeQueue.ts:190 is the e2e String(e) arm, which this PR does not touch).

Verification (this branch, local)

• npx vitest run __tests__/utils/mergeQueue.test.ts: 40 passed (34 on main)
• same, with each of the six mutants applied in turn to src/utils/mergeQueue.ts: 1 failed / 39 passed for every one (mutants reverted, not committed)
• npx eslint __tests__/utils/mergeQueue.test.ts: clean

Related Issue

Refs #523 — the hive consolidated this finding onto that tracker (already_existed: true, consolidated: true); its own trigger.ts boxes are #524's and the folded run.ts:40 / config.ts:657 / command.ts:23 v8 ignore entries still need a src/ change (needs-human: production-file edit outside the quality lane), so the tracker stays open. This PR is the complete fix for the six mergeQueue.ts mutants it names.

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. Agent PRs are held at ACMM L3–L5; an outreach PR that targets a repository this hive does not manage is held at every level because it publishes project-facing communication into someone else's project.

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.

Copilot review performed under the maintainer's explicit authorization to update, review, release reviewed holds, and merge eligible PRs in this cleanup.

Each queue classification alternative has an independent input, and a human login ending in github-actions is explicitly not identified as the bot.

Verified successful build-test, e2e-coverage and DCO results on head 1d6484d. Any folded issue findings remain assigned to the canonical destinations in the updated scope tables.
