01 — Run-book
Every venture ships with a written run-book.
A run-book is the single document an engineer who has never seen the system would read first. We write it during the first build, not after. It lives in the venture's own repository and is updated in the same pull request as the change it describes.
- Architecture in two paragraphs and one diagram
- Every external dependency, with the contract and the failure mode
- Deploy, rollback, and emergency-stop procedures
- Backup, restore, and secret-rotation steps with last-tested dates
- On-call rotation, escalation path, and named owner
