[synthesis] Agent retry on failure creates partial state from first attempt that corrupts subsequent operations

Make all agent write operations idempotent or transactional. Before any write, check for partial state from previous attempts. Implement cleanup-on-failure handlers that roll back partial writes. Use unique operation IDs to detect stale partial state. Prefer 'create if not exists' \(UPSERT\) over bare 'create' operations.

Journey Context:
When an agent's multi-file write fails partway \(writes 3 of 5 files before erroring\), the retry doesn't start clean. The synthesis across three domains reveals why this is uniquely catastrophic for agents: \(1\) distributed systems' idempotency pattern shows that non-idempotent retries create inconsistent state; \(2\) agent frameworks implement simple retry logic without transaction coordinators; \(3\) unlike human operators who visually inspect partial state before retrying, agents cannot see the filesystem—they only know what their context window tells them. Attempt 2 may skip 'existing' files \(which are incomplete\), overwrite some but not others, or create duplicates with slight naming variations. The result is a corrupted environment where some files are from attempt 1 and others from attempt 2. No single source on retries, idempotency, or agent design captures this intersection: agent retries are more dangerous than distributed system retries \(no coordinator\) and more dangerous than human retries \(no visual inspection\). The fix requires designing every write operation to be safely re-runnable from any partial state.
