## Step 2: Playwright E2E Tests (Ntfy)

**Command**: `npx playwright test --project=firefox tests/settings/ntfy-notification-provider.spec.ts`

All 12 tests passed in 1.6 minutes:

| Test | Result |
|------|--------|
| Form Rendering — token field and topic URL placeholder | PASS |
| Form Rendering — toggle between ntfy and discord | PASS |
| Form Rendering — JSON template section | PASS |
| CRUD — create with URL and token | PASS |
| CRUD — create with URL only (no token) | PASS |
| CRUD — edit and preserve token when field left blank | PASS |
| CRUD — test notification | PASS |
| CRUD — delete provider | PASS |
| Security — GET response does NOT expose token | PASS |
| Security — token not in URL or visible fields | PASS |
| Payload Contract — POST body type/url/token structure | PASS |

---

## Step 4: Backend Unit Coverage

**Command**: `cd backend && go test -coverprofile=coverage.txt ./...`

| Package | Coverage |
|---------|----------|
| services | 86.0% |
| handlers | 86.3% |
| notifications | 89.4% |
| models | 97.5% |
| **Overall** | **88.0%** |

Threshold: 85% — **PASS**

---

## Step 5: Frontend Unit Coverage

**Source**: `frontend/coverage/coverage-summary.json` (163 test files, 1938 tests passed)

| Metric | Coverage |
|--------|----------|
| Statements | 89.38% |
| Branches | 81.86% |
| Functions | 86.71% |
| Lines | 90.13% |

Threshold: 85% line coverage — **PASS**

---

## Step 8: GORM Security Scan

**Command**: `/projects/Charon/scripts/scan-gorm-security.sh --check`

- Scanned: 43 Go files (2396 lines)
- CRITICAL: 0
- HIGH: 0
- MEDIUM: 0
- INFO: 2 (missing FK indexes on `UserPermittedHost.UserID` and `UserPermittedHost.ProxyHostID`)
- **Result**: PASSED (no blocking issues)

---

## Step 9: Trivy Filesystem Scan

**Command**: `trivy fs --severity HIGH,CRITICAL --scanners vuln`

- Backend (`/projects/Charon/backend/`): 0 HIGH/CRITICAL
- Frontend (`/projects/Charon/frontend/`): 0 HIGH/CRITICAL
- **Result**: PASSED

Known CVEs from SECURITY.md (all "Awaiting Upstream", not ntfy-related):
- CVE-2025-68121 (Critical, CrowdSec Go stdlib)
- CVE-2026-2673 (High, OpenSSL in Alpine)
- CHARON-2025-001 (High, CrowdSec Go CVEs)
- CVE-2026-27171 (Medium, zlib)

## Step 11: Security Code Review

### Token Handling

| Check | Status | Evidence |
|-------|--------|----------|
| Token never logged | PASS | `grep -n "log.*[Tt]oken" notification_service.go` — 0 matches |
| Token `json:"-"` tag | PASS | `models/notification_provider.go`: `Token string \`json:"-"\`` |
| Bearer auth conditional | PASS | Line 593: `if strings.TrimSpace(p.Token) != ""` — only adds header when set |
| No hardcoded secrets | PASS | Only test file has `tk_test123` (acceptable) |
| Auth header allowed | PASS | `http_wrapper.go` line 465: `"authorization"` in sanitizeOutboundHeaders allowlist |
| Token preservation | PASS | Handler update logic includes ntfy in token preservation chain |

### SSRF Protection

| Check | Status | Evidence |
|-------|--------|----------|
| HTTPWrapper uses SafeHTTPClient | PASS | `http_wrapper.go` line 70: `network.NewSafeHTTPClient(opts...)` |
| SafeHTTPClient blocks SSRF | PASS | `safeclient_test.go` line 227: `TestNewSafeHTTPClient_BlocksSSRF` |
| Cloud metadata detection | PASS | `url_validator_test.go` line 562: `TestValidateExternalURL_CloudMetadataDetection` |

The ntfy dispatch path (`dispatchURL = p.URL` → `httpWrapper.Send()`) uses `SafeHTTPClient` at the transport layer, which provides SSRF protection including private IP and cloud metadata blocking.

### API Security

| Check | Status |
|-------|--------|
| Only admin users can create/modify providers | PASS (middleware-enforced) |
| Token write-only (never returned in GET) | PASS (E2E test verified) |
| `has_token` boolean indicator only | PASS (computed field, `gorm:"-"`) |

### Gotify Token Protection Policy

| Check | Status |
|-------|--------|
| No tokens in logs | PASS |
| No tokens in API responses | PASS |
| No tokenized URLs in output | PASS |
| URL query params redacted in diagnostics | PASS |

## Issues & Recommendations

### Blocking Issues

None.

### Non-Blocking Observations

1. **ESLint warnings (834)**: Pre-existing, zero ntfy-related. Recommend gradual cleanup.
2. **GORM INFO findings**: Missing indexes on `UserPermittedHost` foreign keys. Non-blocking, performance optimization opportunity.
3. **Frontend coverage (branches 81.86%)**: Below 85% but line/statement/function metrics all pass. Branch coverage is inherently lower due to conditional rendering patterns.

---

## Final Verdict

**APPROVED** — The ntfy notification provider implementation passes all mandatory quality and security gates. No blocking issues identified. The feature is ready to ship.
