1. Manifest missing newline 🐞 ⚙

Description

kb/.manifest.json still has no trailing newline at EOF, which can break strict tooling/linters and
creates noisy diffs when regenerated.

Code

kb/.manifest.json[R18-19]

+  "4228375029": "domain_knowledge/pr-closure-explained-by-dependency-on-prior-knowledge-base.md"
}

Evidence

The PR diff for kb/.manifest.json explicitly includes the “No newline at end of file” marker at the
end of the file, indicating it is missing the final newline character.

kb/.manifest.json[17-19]

Closing this automation PR because it was generated from discussion on the rolling KB PR itself. The extractor now skips automation KB PRs entirely, and the demo will be rerun against that fix.
