VAT execution
Read the exact action guide for prerequisites, identifier discovery, supported input, effects, captured successful and refused responses, verification and recovery. Synthetic fixture results do not authorize a live mutation or establish a provider outcome.
- List UK VAT schemes: List effective-dated UK VAT scheme history, optionally including archived records.
- Create UK VAT scheme: Add an effective-dated standard, cash accounting, flat-rate or annual-accounting scheme. Active scheme dates cannot overlap.
- Update UK VAT scheme: Change one VAT scheme record and its effective dates. Active scheme dates cannot overlap.
- Archive UK VAT scheme: Archive one VAT scheme record while preserving its history.
- Restore UK VAT scheme: Restore an archived VAT scheme when its dates do not overlap another active scheme.
Evidence
Actual Books route handlers and the exported Worker were exercised against five local SQLite D1 concern databases with all committed migrations, the real posting Durable Object and local R2. Route captures use synthetic verified Auth; Worker captures use synthetic Auth transports. Nexus, Brand, Notify, Pay, Mercury and Xero responses are explicitly simulated at the provider transport boundary. Captures prove local request/response behavior and canonical SDK projection, not live bank access, payment movement, email delivery, provider eligibility, tax compliance, encrypted custody, scheduled execution, deployment or production completion. Fixture identities, credentials, addresses and records authorize no live operation.
