A system isn’t “resilient” because it has retries. It’s resilient when it survives real conditions without requiring a human to glue it back together.

Most architectures look solid on slides, but they rest on one thing: humans compensating what wasn’t made explicit.

Resilience begins when you refuse: “we’ll see in prod.”

Resilience = normalized restarts
+ explicit failure
+ stable invariants
+ continuity without runbooks
