test(bundle): drive parseProwConfig's empty-document arm (config.ts:373) through dist/index.js

[hivecommons-hive]

Test Improvement

Adds __tests__/bundle/emptyConfigDocument.test.ts, driving the empty-document arm of parseProwConfig (src/utils/config.ts:373, return {} when the loaded yaml is undefined/null) through dist/index.js.

For each of a blank .github/prow.yaml and a bare --- document:

• /lifecycle stale → exit 0, lifecycle: using built-in labels frozen,stale,rotten, exactly one POST /issues/1/labels with lifecycle/stale, and the configuration reads stop at .github/prow.yaml (the empty file is a found source, so no prow configuration found is never raised)
• /kind cleanup → exit 1, kind: yaml malformed, expected 'kind' top level key, no no prow configuration found, no label write

Evidence on main @ aa6a0f8: npm run test:coverage:e2e on origin/main + the heads of all 35 open hold-gated bundle PRs (#283 … #392) left config.ts:373 at 0 hits; with this file it gets 4. Unit coverage already reached the arm via __tests__/utils/config.test.ts:420-426.

Files / functions claimed: __tests__/bundle/emptyConfigDocument.test.ts (new) only; parseProwConfig empty-document arm. Disjoint from #314 (explicit config source), #339 (schema rejections) and #388 (label listing refusals).

A comment-only file belongs in the same table but currently throws YAMLException: expected a document, but the input is empty through the bundle — that is a production defect in the trim() guard, filed as #393 for a maintainer; the test names it and leaves that row out until it is fixed.

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. Non-outreach agents are held at ACMM L3–L5; the outreach agent is always held because it publishes project-facing communication.

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.

The blank-file /lifecycle row (:51) reaches config.ts:373 and every new branch. The other rows add nothing.

• Drop the bare-document-marker row at emptyConfigDocument.test.ts:52 and the /kind it.each at :66–73.

Addressed in 138529c: dropped the --- row and the /kind it.each; the blank-file /lifecycle case stands alone as a plain it (the #393 note about the comment-only shape stays).
