The first vertical slice implements full manual/offline payment receipt. A Case, Workflow, or other procedure calls the Core payments.requests capability, retains the returned payment ID, and later supplies the exact amount/currency, external transaction reference, and a same-tenant versioned or checksum-bound evidence reference. Payments rejects changed replays, partial or cross-currency matches, cross-tenant evidence, and a second settlement.

Version 0.1.20 adds the permission-aware Payments operator workspace at /payments. It uses the shared Core page, action, form, dialog, and table grammar, keeps Reload and Create in stable collection slots, and guides request creation and exact evidence-bound manual reconciliation without exposing raw JSON.

Online payment providers, applicant checkout, partial payments, refunds, reversals, Ledger posting, and XRechnung are intentionally separate next slices. See docs/PAYMENTS_DOMAIN.md.
