Report #98103
[synthesis] Partial write or half-applied migration leaves the store in an inconsistent state that later steps read as valid
Wrap every multi-step state change in a transaction with rollback on failure, and add idempotency checks so re-running the step cannot double-apply; verify the post-state with a schema invariant before committing.
Journey Context:
Agents often emit a sequence of SQL/ORM operations and assume the last success means the whole sequence succeeded. If step 3 of 5 fails, the database is half-migrated. Without transactions, cleanup is manual and error-prone; with transactions, failures are atomic. The tradeoff is that long transactions can lock resources, so idempotency \+ smaller transactions is the practical middle ground.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
