## 1. UAT Overview & Objectives

**Release:** Drop v0.5.0 — Phase 0.5 Security Hardening
**UAT Period:** TBD (before Phase 1 production launch)
**UAT Environment:** `https://drop-staging.fly.dev/`

**Objectives:**
1. Confirm that all Phase 0.5 security hardening features match the agreed acceptance criteria
2. Validate that all original MVP business flows (registration, login, remittance, QR payment) remain intact after security changes
3. Verify that the pass-through model invariant is enforced: Drop NEVER holds customer funds
4. Provide formal business sign-off by Alem Bašić (CEO) for production deployment

**Scope of this UAT:**
- Authentication module (registration, OTP, PIN, login) with security hardening
- Remittance flow (0.5% fee, 6 NOK corridors, mock BaaS)
- QR payment flow (1% fee, mock merchant, mock BaaS)
- Exchange rates API (6 corridors)
- Security features (rate limiting, CSRF, input validation, security headers)
- Database compliance checks (no balance column, no card_number/cvv)

**Out of scope:**
- BankID integration (Phase 2)
- Real BaaS payments (Phase 2)
- Real Sumsub KYC (Phase 2)
- Cards feature (Phase 3)
- Mobile native app (Phase 2)

## 7. Outstanding Issues & Risk Acceptance

### Issues Deferred to Future Release

| # | Issue | Severity | Reason for Deferral | Fix Version | Risk Acceptance By |
|---|-------|----------|--------------------|-----------|--------------------|
| 1 | BankID SCA not integrated — DOB form validation only | Medium | Requires Finanstilsynet PISP/AISP registration (Phase 2) | v1.0.0 | Alem Bašić (CEO) |
| 2 | Sumsub KYC mocked — no real identity verification | Medium | Requires live Sumsub key + AML production config | v1.0.0 | Alem Bašić (CEO) |
| 3 | BaaS payments mocked — no real bank transactions | Medium | Requires SpareBank1 or Swan BaaS partnership (Phase 2) | v1.0.0 | Alem Bašić (CEO) |
| 4 | Cards feature absent | Low | Requires card partner; feature-flagged (Phase 3) | v2.0.0 | Alem Bašić (CEO) |

### Workarounds in Place for Sign-Off

| Issue | Workaround | Acceptable for Production | Accepted By |
|-------|------------|--------------------------|-------------|
| Mock BaaS | `NEXT_PUBLIC_SERVICE_MODE=mock`; no real money movement | Yes — for MVP/staging only; NOT for Phase 1 production | Alem Bašić (CEO) |
| Mock Sumsub KYC | `kyc_status` auto-approved in dev/staging | Yes — for MVP/staging only | Alem Bašić (CEO) |

---

## 8. Go / No-Go Recommendation

### Individual Recommendations

| Participant | Module | Recommendation | Conditions |
|-------------|--------|----------------|------------|
| Validator Agent | All (automated) | **Go** | All 12 AC-series and NF-AC-series tests passing |
| John (AI Director) | Technical | **Go** | Security audit score ≥ 80/100 post-Phase 0.5 hardening |
| Alem Bašić (CEO) | All | TBD | Pending CEO UAT execution |

### Overall Recommendation

**UAT Coordinator recommendation (John):** **Conditional Go**

**Rationale:** Phase 0.5 delivers the security hardening required before BaaS partner discussions and Finanstilsynet submission. All MVP flows remain functional. Three medium-priority Phase 2 blockers (BankID, real BaaS, real KYC) are accepted as deferred. Production deployment of v0.5.0 is safe for staging-only use. Phase 1 production with real users requires BaaS partnership confirmation.
