contract guards, and updates repository configuration. - -### Addressed Issues -- closes #303 -- closes #302 -- closes #301 -- closes #300 - -### Key Changes -- **Auth Routes (`src/routes/auth.routes.ts`)**: Optimized and hardened request validation schemas and error handling wrapper for auth routes. -- **Invoice Service (`src/services/invoice.service.ts`)**: Added `rejectInvoice` functionality with status transition validation, rejection reason persistence, and seller notification. -- **Contract Guard Service (`src/services/stellar/contract-guard.service.ts`)**: Fixed Soroban contract address parsing and ledger key building to prevent cache poisoning on RPC errors. -- **Git Ignore (`.gitignore`)**: Added `mimo` build and configuration artifacts ignore patterns. +Implements KYC document submission, verification status checks, admin review transitions, and invoice submission gating as requested in Issue #475. + +### Scope & Key Implementation: +- **`POST /kyc/submit`**: + - Accepts seller details (`legalName`, `registrationNumber`, `jurisdiction`, etc.) and IPFS document CIDs (`documentCids`, `documentType`, `documentNumber`, `ipfsDocumentUrl`). + - Validates payload structure and stores document CIDs within verification records. + - Sets KYC status to `PENDING`. + - Rejects new submissions with HTTP 409 Conflict if a verification is already `PENDING` or `APPROVED`. +- **`GET /kyc/status`**: + - Returns current verification status (`PENDING`, `APPROVED`, `REJECTED`) for the authenticated seller/wallet. + - Returns `rejectionReason` when status is `REJECTED`, and `null` otherwise. +- **Admin `PATCH /kyc/:id/review`**: + - Allows administrators (authenticated via `x-admin-key` header or admin JWT) to update verification status to `APPROVED` or `REJECTED`. + - Requires rejection reason when rejecting verification. + - Dispatches notifications (`KYC_APPROVED` / `KYC_REJECTED`) and logs audit trail via `logKYCStatusChange`. + - Also mounted on `/admin/kyc/:id/review` and `/api/v1/admin/kyc/:id/review`. +- **Re-submission on Rejected Status**: + - Permitted when user's KYC status is `REJECTED`. + - Archives previous verification record in `KycHistoryRepository`. + - Resets status to `PENDING`, updates document CIDs, and clears previous rejection reason. +- **Invoice Submission KYC Gating**: + - Invoice submission (`POST /invoices` and `POST /api/v1/invoices`) checks seller KYC verification. + - Blocks wallets without approved KYC (`user.kycStatus === 'approved'` or `user.isKycVerified === true`) with HTTP 403 (`KYC_APPROVAL_REQUIRED`), unless `skipVerification` is enabled in configuration. +- **Backwards Compatibility**: + - All endpoints are accessible both directly on `/kyc` and under the `/api/v1/kyc` prefix. + - Legacy webhook and submission routes remain functional. + +Closes #475 + +## Type of Change + +- [ ] 🐛 Bug fix (non-breaking
