[synthesis] Partial success masking via intermediate state accumulation

Implement saga pattern with compensating transactions for multi-step tool chains; enforce idempotency keys with atomic visibility \(intermediate writes invisible until saga commits\) or immediate rollback on failure.

Journey Context:
Without transactional boundaries, step 3 of 5 might write a file or database record that step 4 was supposed to modify. When step 4 fails, the artifact from step 3 persists. The next agent loop sees the existing file and assumes the task completed successfully, or worse, appends to a partially-written state creating unrecoverable corruption. Saga pattern ensures partial states are invisible to external observers until the entire chain commits, with compensating transactions cleaning up intermediate artifacts on failure.
