## ⚠️ Issues Found

### 🔴 Critical Issues: 0

### 🟡 High Priority Issues: 1

**1. Nginx Proxy Manager Not Removed/Migrated**
- **File:** `compose/core/nginxproxymanager/compose.yml`
- **Issue:** Template file still exists with `.yml` extension and no configuration
- **Impact:** Will fail CI validation workflow
- **Recommendation:**
  ```bash
  # Option 1: Remove if not needed (Traefik replaces it)
  rm -rf compose/core/nginxproxymanager/

  # Option 2: Configure if needed alongside Traefik
  # Move to compose.yaml and configure properly
  ```

### 🟠 Medium Priority Issues: 3

**2. Missing Password Synchronization Documentation**
- **Files:** `compose/core/lldap/.env`, `compose/core/tinyauth/.env`
- **Issue:** Password must match between LLDAP and Tinyauth, not clearly documented
- **Recommendation:** Add a note in both .env files:
  ```bash
  # IMPORTANT: This password must match LLDAP_LDAP_USER_PASS in ../lldap/.env
  LDAP_BIND_PASSWORD=changeme_please_set_secure_password
  ```

**3. Vikunja Database Password Duplication**
- **File:** `compose/services/vikunja/compose.yaml`
- **Issue:** Database password defined in two places (can get out of sync)
- **Recommendation:** Use `.env` file for Vikunja service
  ```yaml
  env_file: .env
  environment:
    VIKUNJA_DATABASE_PASSWORD: ${POSTGRES_PASSWORD}
  ```

**4. Immich External Photo Library Mounting**
- **File:** `compose/media/frontend/immich/compose.yaml`
- **Issue:** Added `/media/photos` mount, but Immich uses `UPLOAD_LOCATION` for primary storage
- **Recommendation:** Document that `/media/photos` is for external library import only

### 🔵 Low Priority / Nice-to-Have: 5

**5. Inconsistent Timezone**
- **Files:** Various compose files
- **Issue:** Some services use `America/Los_Angeles`, others don't specify
- **Recommendation:** Standardize timezone across all services or use `.env`

**6. Booklore Image May Not Exist**
- **File:** `compose/services/booklore/compose.yaml`
- **Issue:** Using `ghcr.io/lorebooks/booklore:latest` - verify this image exists
- **Recommendation:** Test image availability before deployment

**7. Port Conflicts Possible**
- **Issue:** Several services expose ports that may conflict
  - Traefik: 80, 443
  - Jellyfin: 8096, 7359
  - Immich: 2283
  - qBittorrent: 6881
- **Recommendation:** Document port requirements in README

**8. Missing Resource Limits**
- **Issue:** No CPU/memory limits defined
- **Impact:** Services could consume excessive resources
- **Recommendation:** Add resource limits in production:
  ```yaml
  deploy:
    resources:
      limits:
        cpus: '1.0'
        memory: 1G
  ```

**9. GitHub Actions May Need Secrets**
- **File:** `.github/workflows/security-checks.yml`
- **Issue:** Some workflows assume `GITHUB_TOKEN` is available
- **Recommendation:** Document required GitHub secrets in README

## 🔍 Detailed Review by Category

### Core Infrastructure

#### Traefik (`compose/core/traefik/compose.yaml`)
✅ **Excellent**
- Proper entrypoint configuration
- HTTP to HTTPS redirect
- Let's Encrypt email configured
- Dashboard with SSO protection
- Log level appropriate for production

**Suggestion:** Consider adding access log retention:
```yaml
- --accesslog.filepath=/var/log/traefik/access.log
- --accesslog.bufferingsize=100
```

#### LLDAP (`compose/core/lldap/compose.yaml`)
✅ **Good**
- Clean configuration
- Proper volume mounts
- Environment variables in .env

**Minor Issue:** Base DN is `dc=fig,dc=systems` but domain is `fig.systems` - this is correct but document why.

#### Tinyauth (`compose/core/tinyauth/compose.yaml`)
✅ **Good**
- LDAP integration properly configured
- Forward auth middleware defined
- Session management configured

**Issue:** Depends on LLDAP - add `depends_on` if deploying together.

### Media Services

#### Jellyfin ✅ **Excellent**
- Proper media folder mappings
- GPU transcoding option documented
- Traefik labels complete
- SSO middleware commented (correct for service with own auth)

#### Sonarr/Radarr ✅ **Good**
- Download folder mappings correct
- Consistent configuration
- Proper network isolation

**Suggestion:** Add Traefik rate limiting for public endpoints:
```yaml
traefik.http.middlewares.sonarr-ratelimit.ratelimit.average: 10
```

#### Immich ⭐ **Very Good**
- Multi-container setup properly configured
- Internal network for database/redis
- Health checks present
- Machine learning container included

**Question:** Does `/media/photos` need write access? Currently read-only.

### Utility Services

#### Linkwarden/Vikunja ✅ **Excellent**
- Multi-service stacks well organized
- Database health checks
- Internal networks isolated

#### File Browser ⚠️ **Needs Review**
- Mounts entire `/media` to `/srv`
- This gives access to ALL media folders
- Consider if this is intentional or security risk

### CI/CD Pipeline

#### GitHub Actions Workflows ⭐⭐⭐⭐⭐ **Outstanding**
- Comprehensive validation
- Security scanning with multiple tools
- Documentation verification
- Auto-labeling

**One Issue:** `docker-compose-validation.yml` line 30 assumes `homelab` network exists for validation. This will fail on CI runners.

**Fix:**
```yaml
# Skip network existence validation, only check syntax
if docker compose -f "$file" config --quiet 2>/dev/null; then
```
