+## Checklist
+
+### 1. Load Testing Results (K6 Baseline)
+
+| Field | Value |
+|-------|-------|
+| **Status** | PARTIAL PASS |
+| **Owner** | SRE Engineer |
+| **Evidence** | [`load-tests/results/BASELINE-REPORT.md`](../load-tests/results/BASELINE-REPORT.md) |
+| **Date tested** | 2026-04-09 |
+
+**Findings:**
+- K6 v1.7.1 baseline run completed against local dev environment
+- 4 test suites executed: Auth, Listings, Search, Payments
+- Latency SLAs met at framework level (p50 < 3ms, p95 < 6ms, p99 < 19ms)
+- Error rate SLA **FAILED** — auth/listings/payments return HTTP 500 due to dev-environment dependency issues (Prisma/DB not fully configured)
+- Search tests skipped (Typesense unavailable in dev)
+
+**Blocker:** Load tests must be re-run against a staging environment with fully operational backend dependencies (PostgreSQL, Redis, Typesense, VNPay sandbox). Framework-level latency is validated; business logic performance is not.
+
+**Required action:**
+- [ ] Provision staging environment with all dependencies
+- [ ] Re-run K6 suites against staging
+- [ ] Validate error rate < 1% across all critical paths
+- [ ] Document production-equivalent load test results
+
+---
+
+### 2. Security Penetration Test Sign-off
+
+| Field | Value |
+|-------|-------|
+| **Status** | FAIL |
+| **Owner** | CTO / DevOps Engineer |

+**Findings:**
+- Automated security scanning exists (`.github/workflows/security.yml`, `.github/workflows/codeql.yml`)
+- No formal third-party or manual penetration test has been conducted
+- No security sign-off document exists
+
+**Blocker:** Production launch requires a formal security assessment covering OWASP Top 10, authentication flows (JWT, OAuth, CSRF), payment endpoint security, and API authorization boundaries.
+
+**Required action:**
+- [ ] Schedule penetration test (internal or third-party)
+- [ ] Scope: auth flows, payment callbacks (VNPay/MoMo/ZaloPay), admin endpoints, file upload, geospatial API
+- [ ] Remediate critical/high findings
+- [ ] Obtain signed pen-test report and remediation confirmation
+
+---
+
+### 3. Monitoring Alert Thresholds Configured
+
+| Field | Value |

+- Test infrastructure: Playwright with global setup/teardown
+- Organized by domain: `api/` (backend API tests), `web/` (frontend browser tests), `load/` (load scenario tests)
+- **2 tests currently failing** (per last Playwright run)
+- No saved `test-results/.last-run.json` available for detailed failure analysis
+
+**Blocker:** All E2E tests must pass before production launch.
+
+**Required action:**
