GitHub Actions 5bafd92edf fix: supply slack webhook token in handler create sub-tests 
The slack sub-tests in TestDiscordOnly_CreateRejectsNonDiscord and
TestBlocker3_CreateProviderRejectsNonDiscordWithSecurityEvents were
omitting the required token field from their request payloads.
CreateProvider enforces that Slack providers must have a non-empty
token (the webhook URL) at creation time. Without it the service
returns "slack webhook URL is required", which the handler does not
classify as a 400 validation error, so it falls through to 500.

Add a token field to each test struct, populate it for the slack
case with a valid-format Slack webhook URL, and use
WithSlackURLValidator to bypass the real format check in unit tests —
matching the pattern used in all existing service-level Slack tests.

# QA Audit Report — Slack Sub-Test Fixes
**Date:** 2026-03-15
**Branch:** `feature/beta-release`
**Commit:** `6e4294dc` — `fix: validate Slack webhook URL at provider create/update time`
**Scope:** Two handler test files + service test + notification_service.go (Slack URL validation)
**Reviewer:** QA Security Agent
---
## Overall Verdict: PASS
All quality and security gates pass. The two test-only fixes are safe, coverage is maintained above threshold, and no security regressions were introduced.
---

## 1. Backend Test Suite
**Command:** `bash /projects/Charon/.github/skills/scripts/skill-runner.sh test-backend-coverage`
| Metric | Result | Threshold |
|---|---|---|
| Test failures | **0** | 0 |
| Statement coverage | **87.9%** | ≥87% |
| Line coverage | **88.2%** | ≥87% |
All packages returned `ok`. No `FAIL` entries. Selected package breakdown:
| Package | Coverage |
|---|---|
| `internal/api/handlers` | 86.3% |
| `internal/api/middleware` | 97.2% |
| `internal/api/routes` | 89.5% |
| `internal/caddy` | 96.8% |
| `internal/cerberus` | 93.8% |
| `internal/metrics` | 100.0% |
| `internal/models` | 97.3% |
| `internal/services` | included in global |
---
## 2. Patch Coverage (Local Patch Report)
**Command:** `bash /projects/Charon/scripts/local-patch-report.sh`
| Scope | Changed Lines | Covered | Patch Coverage | Threshold |
|---|---|---|---|---|
| Overall | 81 | 77 | **95.1%** | ≥90% |
| Backend | 75 | 71 | **94.7%** | ≥85% |
| Frontend | 6 | 6 | **100.0%** | ≥85% |
**4 uncovered changed lines** in `notification_service.go` at lines 477–478 and 481–482. These are error-handling branches for `json.Marshal` and `bytes.Buffer.Write` in Slack payload normalization — conditions requiring OOM-class failures and effectively unreachable in practice. Not a coverage concern.
---
## 3. Pre-Commit Hooks
**Commands:** `lefthook run pre-commit`; `go vet ./...`; `golangci-lint`
| Hook | Result |
|---|---|
| `end-of-file-fixer` | PASS |
| `trailing-whitespace` | PASS |
| `check-yaml` | PASS |
| `actionlint` | PASS |
| `dockerfile-check` | PASS |
| `shellcheck` | PASS |
| `go vet ./...` (manual) | PASS — 0 issues |
| `golangci-lint` v2.9.0 (manual) | PASS — 0 issues |
Go and frontend hooks were skipped by lefthook (no staged files). Both were run manually and returned clean results.
---
## 4. Trivy Filesystem Scan
**Command:** `bash /projects/Charon/.github/skills/scripts/skill-runner.sh security-scan-trivy`
Scanners: `vuln,secret`. Severity filter: `CRITICAL,HIGH,MEDIUM`.
| Target | Type | Vulnerabilities | Secrets |
|---|---|---|---|
| `backend/go.mod` | gomod | **0** | — |
| `frontend/package-lock.json` | npm | **0** | — |
| `package-lock.json` | npm | **0** | — |
| `playwright/.auth/user.json` | text | — | **0** |
**Result: 0 findings.**
---
## 5. GORM Security Scan
**Command:** `bash /projects/Charon/.github/skills/scripts/skill-runner.sh security-scan-gorm`
Scanned 41 Go files (2,253 lines).
| Severity | Count |
|---|---|
| CRITICAL | **0** |
| HIGH | **0** |
| MEDIUM | **0** |
| INFO | 2 (pre-existing, informational only) |
**Result: 0 actionable issues.**
---
## 6. Security Review: `WithSlackURLValidator`
The new `WithSlackURLValidator` functional option exposes a test-injectable hook in `NotificationService`.
| Concern | Assessment |
|---|---|
| SSRF via production bypass | **Not a risk.** `NewNotificationService` always defaults to `validateSlackWebhookURL`. The option must be explicitly passed at construction time. |
| Allowlist strength | Regex `^https://hooks\.slack\.com/services/T[A-Za-z0-9_-]+/B[A-Za-z0-9_-]+/[A-Za-z0-9_-]+$` — pins to HTTPS, exact domain, and enforced path structure. Robust against SSRF. |
| Test bypass scope | Only used in `*_test.go` files. Comment states: *"Intended for use in tests that need to bypass real URL validation without mutating shared state."* |
| Exported from production package | **LOW / Informational.** The option is exported from `services` with no `//go:build test` build-tag guard. It could theoretically be called from production code, but there is no evidence of misuse and the default is safe. Consider adding a build-tag guard in a future cleanup pass if stricter separation is desired. |

## 4. Verification Greps
### 4a. All `mccutchen/go-httpbin` `docker run` instances have `-e PORT=80`
```
scripts/cerberus_integration.sh:174: docker run ... -e PORT=80 mccutchen/go-httpbin
scripts/waf_integration.sh:167: docker run ... -e PORT=80 mccutchen/go-httpbin
scripts/rate_limit_integration.sh:187:docker run ... -e PORT=80 mccutchen/go-httpbin
scripts/coraza_integration.sh:158: docker run ... -e PORT=80 mccutchen/go-httpbin
```
Remaining `mccutchen/go-httpbin` matches are `docker pull` lines (no `-e PORT` needed).
**Result: PASS** — 4/4 confirmed.
### 4b. Zero executed `docker exec ... curl` calls
Only 2 matches found in `scripts/verify_crowdsec_app_config.sh` (L94–95) — both inside `echo` statements (user hint text, not executed). Confirmed by manual review.
**Result: PASS** — 0 executed `docker exec ... curl` calls.
---
## 5. Security Review
| Check | Result | Notes |
|-------|--------|-------|
| Secrets/credentials in diff | PASS | `git diff | grep -iE "password\|secret\|key\|token\|credential\|auth"` — no matches |
| Gotify tokens | PASS | `grep -rn "Gotify\|gotify\|token="` across all 6 scripts — no matches |
| Injection vectors | PASS | `-e PORT=80` is a static literal; no user-controlled input flows into new code |
| Command injection | PASS | `wget -qO` flags are hardcoded; no interpolated user input |
| SSRF | N/A | URLs are internal container addresses (127.0.0.1, localhost) in CI-only scripts |
| Sensitive data in logs | PASS | No new log/echo statements added |
| URL query parameters | PASS | No tokenized URLs (e.g., `?token=...`) in changed or adjacent code |

## Remaining Validation (CI)
The integration scripts cannot be executed locally without a built `charon:local` image and Docker network. Full end-to-end validation will occur when the PR triggers CI:
- `.github/workflows/cerberus-integration.yml`
- `.github/workflows/waf-integration.yml`
- `.github/workflows/rate-limit-integration.yml`
- `.github/workflows/crowdsec-integration.yml`
