Objective
Transient failures succeed; 4xx stop; destination unique; attempts logged.
| # | Success condition |
|---|---|
| 1 | 5xx retried with bound + jitter or Retry-After |
| 2 | 4xx not retried |
| 3 | Payload unique in the destination |
| 4 | run.log records attempts |
| # | Visible instruction |
|---|---|
| 1 | Use the flaky writer stub. |
| 2 | Honor Retry-After when present. |
| 3 | Make the write idempotent on payload_id. |
Hidden tests score the final tables or files, not the exact syntax you used. Test implementation is never shown to participants.
