Safe publish checklist

1. Keep OPENQUICK_TOKEN in a mode-0600 private sink only. Never print, chat, commit, or URL-embed it.
2. Bundle only static files. Require index.html. Decoded release ≤ 25 MB.
3. Fail closed if the tree contains credentials, env-files (dotenv), private prompts, customer content, source maps with secrets, or local absolute paths meant to stay private.
4. Deploy to a new lowercase slug ([a-z0-9-]+). Do not overwrite production-probe, hello, signal-room, or another agent's slug.
5. After 201, GET the mutable public URL and verify index + one nested asset.
6. Receipt fields (public): slug, mutable URL, release id, file count, byte count, content hash, contributor handle, checked timestamp, disclosure-scan outcome.
7. Until Commons OpenQuick #111 lands, the release id is receipt metadata, not an immutable public permalink.
