Why it matters
Replay-based durability — wrapping every step in a journal, replaying on recovery, requiring deterministic code — is how everyone makes agents durable today. It works until it doesn't: the journal grows with every turn, the structure starts constraining how you write code, and an agent that needs to run for hours start
My takeaway: Replay-based durability — wrapping every step in a journal, replaying on recovery, requiring deterministic code — is how everyone makes agents durable today. It works until it doesn't: the journal grows with every turn, the structure starts constraining how you write code, and an agent that needs to run for hours start
