Test Improvement

Files: __tests__/cronJobTest/sweep.test.ts only. No src/, dist/, docs/ or eslint.config.mjs change — disjoint from #510 (src/utils/auth.ts, dist/index.js), #511 (docs/contributing.md), #512 (__tests__/label/remove.test.ts, eslint.config.mjs) and #514 (__tests__/utils/labelMatch.test.ts, __tests__/utils/command.test.ts).

A single-operator mutation probe over src/cronJobs/* and src/plugins/{ownersLabel,blunderbuss,requireMatchingLabel,lgtmBinding}.ts on main @ 88241f4 (258 mutants; details on #515) left four non-equivalent survivors against their full vitest related set, all in src/cronJobs/sweep.ts. Four cases pin them:

• sweep candidates › includes a pull request updated exactly at the start of the window — sweep.ts:178 (>= on updated_at).
• sweep candidates › a full page whose oldest entry sits exactly on the start of the window is not the last page — sweep.ts:179 (the exhausted fold); asserts page=1 and page=2 were listed via servePulls's listCalls.
• sweep on a repository with OWNERS files › a pull request opened exactly at the start of the window is fresh and gets reviewers — sweep.ts:149 (< on created_at).
• sweep on a repository with OWNERS files › a fresh pull request by an author in blunderbuss.ignore_authors gets no reviewers — sweep.ts:163 (explicit: false); configures ignore_authors: [Dave] through prowYaml, asserts the requested_reviewers POST is not made and core.debug logs blunderbuss: ignoring pull request by dave (also pins the case-insensitive match).

Verification (this branch, local)

• npx vitest run __tests__/cronJobTest/sweep.test.ts: 35 passed (31 on main)
• same, with each mutant applied to src/cronJobs/sweep.ts in turn: :149 1 failed, :163 1 failed, :178 3 failed, :179 1 failed (mutants reverted, not committed)
• npx eslint __tests__/cronJobTest/sweep.test.ts: clean
• The msw "unhandled request" noise the file prints (POST /graphql, GET /branches/master) is the pattern main already prints for the existing 100-pull-request paging test; the 100-pull-request case here adds the same.

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 sweep cases observe inclusive time boundaries, continuation beyond a full page ending at the boundary, and the case-insensitive ignored-author no-write behavior.

Verified successful build-test, e2e-coverage and DCO results on head 71a1ab1. Any folded issue findings remain assigned to the canonical destinations in the updated scope tables.
