Reviewed diff chunks: 3
Advisory LLM verdict: APPROVE
Advisory summary: Reviewed all 3 diff chunk(s). Documentation-only governance housekeeping chunk: updates CHANGELOG.md, README.md, TODO.md, and project/README.md ticket index. No code, secrets, workflow, or test changes. Content is consistent with described ticket closures. | Governance-only documentation PR adding ticket-029 scaffold, closing ticket-028 (DONE/DONE), and extending the ticket index. All changes are non-code markdown/JSON governance artifacts with consistent metadata. The single test result (governance / remote lifecycle) is PASS. | Governance housekeeping chunk adding ticket-029 metadata and preprompt files. The visible diff only adds documentation and governance scaffolding; no executable code, secrets, workflow changes, or destructive actions are introduced. The preprompt correctly restricts execution scope and requires new authority for sensitive operations.
