Test Improvement

Pins six behaviours of src/plugins/tide.ts that a 50-mutant single-site probe showed no test asserts (each mutant passed the full npx vitest related src/plugins/tide.ts --run set, 60 files / 1166 tests, on a clean main@88241f4). Test-only; src/ and dist/ are untouched.

__tests__/plugins/tideMergeQueue.test.ts

• Both merge_queue: off tests assumed an unhandled /graphql request would fail them. It does not: queueState swallows the failed read with one core.warning and falls back to a direct merge, so "always call queueState" survived. They now serve /graphql with the call counter and assert calls is empty (and, in the 405 case, that no warning fired).
• New: a pr without a draft field whose mergeable_state is draft is refused, not enqueued — the only path to queueRefusedStates' 'draft' entry, since blockedReason catches draft: true first and getPull defaults a missing field to false.

__tests__/plugins/tide.test.ts

• New: does not wait for an unknown state on a draft pr — one GET, no sleep; pins blockedReason's draft check as distinct from the later mergeable_state check.
• New in the fork-403 describe: exactly five workflow files are all listed, with no "and 0 more" (fileList's > 5), and only paths under the top-level .github/workflows/ count — docs/.github/workflows/… and templates/.github/workflows/… (which this repository ships) are not workflow files (startsWith, not includes).
• New in getPull: a head whose repository is gone (head.repo: null) is not a fork.

After this change all six mutants are killed (re-run of the same probe against the direct tide test files). The two remaining survivors — state === 'open' → !== 'closed' in getPull and tideOnComment — only differ for a state GitHub never emits and are deliberately not tested.

Verification: npx vitest run __tests__/plugins/tide.test.ts __tests__/plugins/tideMergeQueue.test.ts — 141 passed; npx eslint on both files clean.

Occupied ground: __tests__/plugins/tide.test.ts (getPull, tryMergePullRequest state cases, fork-403 describe) and __tests__/plugins/tideMergeQueue.test.ts (draft and merge_queue: off cases). Disjoint from #510, #511, #512, #514, #516.

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.

The cases separately observe no GraphQL when the queue is off, draft refusal without retries, top-level-only workflow diagnosis, the exact five-file boundary, and deleted-head-repository handling.
