Rules and limits
- The model locks the database row FOR UPDATE and updates only a pending record.
- A second or concurrent submission receives the current already-signed outcome rather than replacing evidence.
Check it worked
- The requested record, output or setting is created or updated through the supported module flow.
- Any related status, count, email, audit/event, PDF/file or queue evidence agrees with the source action.
- An error message is investigated rather than bypassed.
Security, privacy and operational checks
- Apply least privilege and verify the correct customer, lead, sales document or recipient before processing.
- Protect public tokens, recipient data, IP/browser evidence, templates and exported files according to organisational policy.
- Test configuration changes with controlled records before production-wide use.
- Retain or delete evidence only under an authorised retention process.
