Report #104114

[synthesis] Retry loop on a partial failure produces an irreversible mixed state

Make every mutating action idempotent and reversible, snapshot state before retries, and never retry in place without rollback.

Journey Context:
Distributed-systems literature teaches that retries without idempotency create duplicate or half-applied state, yet agent tools often retry blindly. If step three of five partially succeeds and the agent retries, it may double-apply a change or leave the environment in an inconsistent mix. Idempotency keys and snapshots are standard backend practice but still rare in agent runtimes.
