Readiness & Ownership
What a service owes before it carries traffic — an owner, a runbook that encodes understanding, dashboards, alerts, a rollback plan and a tested recovery path.
The conversation before a service carries real traffic: who owns it, how you will know it is broken, and how you get back.
Making the owner of a service retrievable at 3am by a stranger — the record, what it contains, how it decays, and how transfers actually work.
A document written for someone tired, under pressure, who did not build this: symptom, possible causes, checks, mitigation, escalation, and how to verify recovery.
"Restart the service" is ritual. "Restart only after checking X, because Y indicates Z" is understanding — and the difference decides what happens when reality does not match the entry.
Status per dimension with evidence — READY, PARTIAL, MISSING, UNKNOWN — and deliberately never a number, because a number invites optimising the number.
