Report #52083

[synthesis] State-mutation-free retry loops guarantee identical failure while exhausting context window

Implement 'escalating retries' that mutate context between attempts—add error logs, adjust temperature/parameters, or escalate privileges; never retry with identical state

Journey Context:
Standard retry patterns \(exponential backoff, circuit breakers\) assume transient network failures that resolve with time. But LLM agent failures are often deterministic given identical context—the same prompt produces the same error \(e.g., persistent hallucination, consistent parsing failure\). Simple retry loops burn tokens and context window without progress. Worse, they often include the error message in context, poisoning future steps with accumulated failure states. The missing insight: retries must mutate state, not just wait. Solutions: \(1\) 'escalation retries' that add more detailed instructions, switch to higher-capacity models, or use different tool selections on failure, \(2\) error log rotation that prevents error message accumulation in context, \(3\) 'circuit breaker with fallback' that switches to a different approach rather than retrying the same failed approach, \(4\) temperature adjustment between retries to break deterministic loops.
