Summary

• Add regression coverage ensuring the package-content checker rejects a declared bin target absent from the npm archive.
• The check verifies the exact missing path and failing exit status.

Verification

• node --test test/package-content.test.js
• npm test (27 tests)
• npm run build
• npm run smoke
• npm run package:smoke
• git diff --check
• Manual review completed

Risk Level

• Low

Notes:

One commit: test: reject missing declared bin targets. Only test/package-content.test.js changed. CI workflow triggers only validation on pull requests; no release, deploy, or package publishing workflow is triggered.

Rollback Plan

• Revert this test-only commit.

Human Decision Needed

• Maintainer review
