Cross-cutting playbooks
Patterns that span multiple lifecycle areas.
- The autonomy ladder — how to promote an action C → B → A safely.
- The watchdog pattern — independent fact-checking that makes autonomous public action safe.
- Designing scheduled jobs — cron design: silent-on-no-op, deterministic-where-possible, the heartbeat pattern.
- The triage scoreboard — turning a pile of open work into a ranked, evidence-tagged review queue.
- Resilience & self-healing — keeping the maintenance system itself healthy: layered supervision (OS + app watchdog), the pre-restart guard, the reconcile pattern for hand-maintained ledgers, and the flake ledger.
