Test Improvement

src/labels/hold.ts cancelHold releases the hold labels by lower-casing both the configured hold.label / legacy hold names and the issue's labels. Neither side of that fold was asserted: every cancel fixture in __tests__/label/hold.test.ts carries do-not-merge/hold and hold in lower case, and both hold.label fixtures are lower case too. A 14-mutant single-operator probe of hold.ts against its six direct suites left exactly two non-equivalent survivors — dropping .toLowerCase() on line 70 (the wanted set) or line 71 (the issue's labels). Either one leaves a label created as Hold or DO-NOT-MERGE/HOLD stuck on the pull request after /hold cancel, while meetsMergeGate (pinned for Hold in __tests__/utils/mergeGate.test.ts) keeps blocking the merge.

Two cases added to the cancel block of __tests__/label/hold.test.ts:

• /hold cancel on an issue carrying Hold and DO-NOT-MERGE/HOLD → observes DELETE …/labels/Hold and DELETE …/labels/DO-NOT-MERGE%2FHOLD (removed under their own names), no setFailed — kills the line-71 mutant
• hold.label: Do-Not-Merge/Hold with the issue carrying do-not-merge/hold → observes DELETE …/labels/do-not-merge%2Fhold and no DELETE for the configured spelling — kills the line-70 mutant

Test-only. Files: __tests__/label/hold.test.ts (describe('hold') › describe('cancel')). No src/ or dist/ change. Disjoint from every open held PR (#510–#540): none touches __tests__/label/hold.test.ts or src/labels/hold.ts (#512 is label/remove.test.ts, #539 is label/label.test.ts + label/lifecycle.test.ts).

Verification (this branch, local)

• npx vitest run __tests__/label/hold.test.ts: 21 tests pass (19 before)
• npx eslint __tests__/label/hold.test.ts: clean
• probe re-run on hold.ts with the new file: both .toLowerCase() mutants KILLED; the only survivor is the equivalent swap of the two names inside the Set
• npm run test:coverage on main @ 88241f4: 163 files / 2206 tests, 100 / 99.75 / 100 / 100; npm run test:coverage:e2e: 99.96 / 98.79 / 100 / 99.95 — hold.ts at 100 % in both, so this is a mutation-robustness pin, not a coverage gap

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.

Both issue-label casing and configured hold-label casing are independently exercised; DELETE requests use the existing label's actual spelling.

Verified successful build-test, e2e-coverage and DCO results on head cd08852. Any folded issue findings remain assigned to the canonical destinations in the updated scope tables.
