Do not equate architecture with determination
The event layer is global. The determination layer is jurisdiction-specific. A registry row is not a tax engine.
| Jurisdiction | Event model | Determination | Receipt |
|---|---|---|---|
| EU VAT | SUPPORTED | SUPPORTED | V1 SUPPORTED |
| UK VAT | SUPPORTED | EXPERIMENTAL | UNSUPPORTED |
| US sales tax | SUPPORTED | MANUAL_REVIEW | UNSUPPORTED |
| Canada GST/HST/PST/QST | SUPPORTED | MANUAL_REVIEW | UNSUPPORTED |
| Other countries | REPRESENTABLE | NOT_VERIFIED | UNSUPPORTED |
Receipt v2 is experimental and generic. Production EU issuance remains fiscal402.receipt/1.0.0.
