When it appears
This path is uncommon on the first CargoWise outbound push. The normal income path arrives unstamped; Lambda stamps through Facturapi and then returns artifacts. Stamped externally appears when CargoWise already carries an outside SAT UUID — for example a CFDI issued before Lambda owned the route, or evidence that only arrives with a later push.What Lambda does
- Records the external stamp evidence on the document
- Leaves the fiscal result as observed, not re-created
- Continues downstream work that only needs verified parent stamp evidence when that evidence is usable
- Create a second CFDI for the same document
- Quietly replace an external UUID with a Lambda-issued stamp
