Durable Execution

Your code will crash. Durable execution means: when it restarts, it picks up where it left off — not from the beginning.

Traditional:  start → step1 → step2 → crash → lost
Queue-based:  start → step1 → step2 → crash → retry from top → duplicates
Durable:      start → step1 → step2 → crash → replay to step2 → continue from step3

Everything else — frameworks, protocols, infrastructure — is implementation detail.
