Test Improvement

A single-operator mutation probe over src/plugins/lgtmBinding.ts (38 mutants against the ten suites that exercise the module, 338 tests) left four non-equivalent survivors. This pins each of them in __tests__/plugins/lgtmBinding.test.ts:

line	mutant	new assertion
38	hasLgtmLabel: .some → .every	['approved', 'lgtm', 'kind/bug'] → true (a PR labelled lgtm and anything else still carries lgtm; tide.ts:184 gates the stale-binding strip on this)
38	hasLgtmLabel: drop .toLowerCase()	['LGTM'] → true
94	unbindLgtm: slice(0, 140) → slice(0, 141)	the pending body is read for the first time: exactly { state: 'pending', context: 'prow/lgtm', description: 140 chars } from a 200-char input
114	isLgtmBound: per_page: 100 → 30	per_page=100 on the GET /commits/abc/status URL

Also asserted, as the negative side of the hasLgtmLabel table: ['approved', 'kind/bug'] and [] → false.

Files: __tests__/plugins/lgtmBinding.test.ts only (+34 lines, one import widened). No src/, dist/ or docs change. Disjoint from every open held PR (#510–#539): none touches __tests__/plugins/lgtmBinding.test.ts or src/plugins/lgtmBinding.ts. hasLgtmLabel is pinned here at the unit level rather than through a tide fixture because __tests__/plugins/tide.test.ts is #518's.

Verification (this branch, local)

• npx vitest run __tests__/plugins/lgtmBinding.test.ts: 23/23 pass (was 18)
• each of the four mutants applied in turn to src/plugins/lgtmBinding.ts, same command: the .every mutant fails 2 tests, the other three fail exactly 1 each; src/ restored, git status clean apart from the test file
• npx eslint __tests__/plugins/lgtmBinding.test.ts: clean

Related Issue

Refs #523 — this ticks the lgtmBinding.ts mutation finding folded onto that tracker (filed this kick); the tracker's other folded findings (trigger, approveReview, mergeQueue, run.ts/config.ts v8-ignore, command.ts:23) are separate deliverables, two of which need a src/ change (needs-human: production-file edit outside the quality lane).

Filed by quality agent (hold-gated mode). Human review required.

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 distinguish any matching LGTM label from all labels matching, preserve case-insensitive recognition, and assert the pending status body, truncation and pagination.

Verified successful build-test, e2e-coverage and DCO results on head b37a76e. Any folded issue findings remain assigned to the canonical destinations in the updated scope tables.
