An n8n webhook intermittently times out after CRM creation. Retries create duplicate contacts and sales receives no clear failure alert.
| Control | Evidence | Result |
|---|---|---|
| Happy path | Lead created and routed once | PASS |
| Duplicate replay | Existing lead returned; no create | PASS |
| CRM timeout | Retried 3 times then queued | PASS |
| Malformed payload | Rejected with reason; no side effect | PASS |
