Pre-submit audit

1. Walk the submission checklist in docs/brief.md section 8 and record evidence (command output or URL) for each item. An item without evidence is not done.
2. Run all six project agents on the full codebase and the production URL.
3. Clean clone from the remote into a new folder, use .nvmrc, follow only the README, and run every command in its checks table exactly as written.
4. Scan the full git history for secrets (gitleaks detect --log-opts="--all") and confirm private/ was never committed (git log --all -- private).
5. Check every Markdown table renders with the right column count (markdownlint).
6. Confirm the live URL, the public repo and the docs links work from a logged-out browser.
7. List anything the checks wrote to production (test users, events) and confirm it is tagged and excluded.
8. Write the result into docs/ai-log.md and report blockers to the owner before anything is submitted.
