[synthesis] Agent retries a failed operation but partial state from the first attempt corrupts the retry environment

Use atomic write patterns for all file operations: write to a temp file then rename \(POSIX rename is atomic\). Before any retry, run an explicit 'clean slate' check that verifies no residual state from the prior attempt exists. Add idempotency keys to stateful API calls.

Journey Context:
Distributed systems solved partial-write corruption with atomic commits and idempotency keys. Autonomous agents face a unique amplification: they retry automatically without human review of partial state. A failed mkdir might have created the directory before failing on permissions; the retry sees the directory exists and assumes success. A failed API call might have committed on the server but timed out on the client; the retry duplicates the resource. The agent cannot distinguish 'I created this' from 'this already existed' without explicit state tracking. Atomic operations and pre-retry cleanup are not optional niceties — they are the difference between a self-healing agent and a self-corrupting one.
