Root cause The charge path was append-only. After a gateway timeout, the fake provider had already accepted a charge, but retrying with the same idempotency key created a new provider charge and the ledger had no local idempotency lookup to return an existing local charge. Files Changed
Validation Command: Result: passed, 1 test run. Remaining Risk This is still an in-memory implementation. A production version would need persistent idempotency storage with transaction/concurrency protection, and likely validation that reused idempotency keys match the original customer and amount. |
Root cause: no idempotency-key lookup; timeout lost the accepted provider charge locally, and retries created new charge records. Files changed:
Validation: Remaining risk: idempotency state is in-memory only; no durable/concurrent store in this fixture. |
Result: both fixed the retry bug and passed python3 -m unittest -v. Answer length: 1022 chars vs 520 chars, 49% shorter. |
