WorkflowPatchInvoice trigger fallback proof.
A redacted or synthetic proof that compares a QuickBooks-style invoice export with Zapier run history. It catches late or missing triggers, duplicate runs, missing Stripe links, void invoices, and malformed rows before any client-facing invoice email is sent.

Input
Seven mock invoices and six mock Zap trigger runs with created times, trigger times, and payment-link readiness.
Output
Safe rows become review-ready invoice events; late rows are recovered and flagged with evidence.
Failure Path
Missing triggers, duplicate runs, missing payment links, void invoices, and missing emails stay blocked.
| Invoice | Trigger State | Decision | Evidence | Next Step |
|---|---|---|---|---|
| INV-1001 | 3 minute delay | Ready for review | Stripe link present and one Zap run found. | Review draft before client send. |
| INV-1002 | 156 minute delay | Late but recovered | Instant trigger arrived in a burst hours after creation. | Fallback review confirms staff did not wait on the trigger. |
| INV-1004 | Payment link missing | Blocked send | Zap triggered before Stripe link was ready. | Hold client email until the payment link appears. |
