+# DashCaddy Project Guidelines for AI Assistants
+
+## HARD RULE: Docker Storage on E: Drive
+
+**ALL Docker container data, volumes, bind mounts, and app configs MUST use `E:/dockerdata/` via bind mounts or CIFS volumes. No exceptions.**
+
+- E: is a network share (`\\Sami-pc\e_share`) shared across all home network computers
+- The ONLY thing allowed on C: is the Docker Desktop WSL engine VHD (`C:/dockerdata/DockerDesktopWSL/`) — this is the absolute bare minimum WSL2 requires (local NTFS). WSL2 cannot create VHDs on network shares.
+- Keep C: Docker usage under 5GB
+- When deploying new containers, always use `E:/dockerdata/<app-name>/` for bind mount paths
+- For CIFS volumes in docker-compose, use `//Sami-pc/e_share/dockerdata/...` as the device path
+
+## CRITICAL: Production vs Development Paths
+
+### Production Files (LIVE - what actually runs)
+```
+C:/caddy/

+
+## Docker Container Mount Points
+
+The `caddy-api` container mounts production files:
+
+| Container Path | Host Path (Production) |
+|----------------|------------------------|
+| `/app/services.json` | `C:/caddy/services.json` |
+| `/app/dns-credentials.json` | `C:/caddy/dns-credentials.json` |
+| `/caddyfile` | `C:/caddy/Caddyfile` |
+| `/app/assets` | `C:/caddy/sites/status/assets` |
+
+## When Making Changes
+
+### To add/remove services from dashboard:
+Edit `C:/caddy/services.json` (NOT e:/CaddyCerts/sites/caddy-api/services.json)
+
+### To modify Caddy reverse proxy rules:
+Edit `C:/caddy/Caddyfile`, then reload via:
+```bash
+curl -X POST http://localhost:2019/load -H "Content-Type: text/caddyfile" --data-binary @"C:/caddy/Caddyfile"
+```
+
+### To modify API server code:
+Edit `e:/CaddyCerts/sites/caddy-api/server.js`, then:
+1. Copy to production: `C:/caddy/sites/caddy-api/`
+2. Restart container: `docker restart caddy-api`
+
+### To modify app templates:
+Edit `e:/CaddyCerts/sites/caddy-api/app-templates.js`
+(Templates are loaded at runtime, changes require container restart)
+
+### To modify dashboard UI:
+Edit `e:/CaddyCerts/sites/status/index.html`
+Copy to `C:/caddy/sites/status/` for production
+
+### To modify DashCA (CA certificate distribution):
+Edit files in `e:/CaddyCerts/sites/ca/`, then:
+1. Regenerate certificate formats: `cd e:/CaddyCerts/sites/ca/scripts && bash generate-all.sh`
+2. Copy to production: `cp -r e:/CaddyCerts/sites/ca/* C:/caddy/sites/ca/`
+3. Reload Caddy if Caddyfile changes were made
+
+## DashCA - Certificate Authority Distribution
+
+**Purpose**: Provides a one-click installation page for the root CA certificate, allowing users to easily trust *.sami domains on any device.
+
+**Access**: https://ca.sami (or https://ca.yourdomain for other installations)
+
+### File Locations

+└── assets/
+```
+
+### Certificate Source
+
+Caddy's built-in PKI generates certificates at:
+- **Root CA**: `C:/caddy/certs/pki/authorities/local/root.crt`
+- **Intermediate CA**: `C:/caddy/certs/pki/authorities/local/intermediate.crt`
+
+**Certificate Info:**
+- **CN**: Sami Home Network Root CA
+- **Algorithm**: ECDSA P-256 with SHA-256
+- **Valid Until**: Dec 22, 2034 (~10 years)
+- **Fingerprint**: `08:98:A5:63:F5:A1:A2:58:5F:02:D7:A8:A2:54:87:E6:BC:33:96:21:29:0E`
+
+### Deployment
+
+DashCA is a **static site** (not Docker-based), deployed via the app selector:
+1. Navigate to App Selector in dashboard
+2. Find "DashCA" in Security category
+3. Click Deploy
+4. System automatically:
+   - Creates `C:/caddy/sites/ca/` directory
+   - Copies files from development directory
+   - Generates certificate formats (DER, mobileconfig)
+   - Adds ca.sami block to Caddyfile
+   - Reloads Caddy configuration
+   - Registers service in `services.json`
+
+### Updating Certificates
+
+When Caddy's CA certificate is renewed (every ~10 years):
+
+```bash
+# 1. Regenerate all certificate formats
+cd e:/CaddyCerts/sites/ca/scripts
+bash generate-all.sh
+
+# 2. Update fingerprint in installation scripts
+# Edit install.ps1 - update $ExpectedFingerprint
+# Edit install.sh - update EXPECTED_FP
+
+# 3. Copy to production
+cp -r e:/CaddyCerts/sites/ca/* C:/caddy/sites/ca/
+
+# 4. Notify users via dashboard or email
+```
+
+### API Endpoints
+
+- **GET /api/ca/info** - Returns certificate metadata (name, fingerprint, expiration, etc.)
+- **GET /api/health/ca** - Returns CA expiration health status
+  - `healthy`: >90 days remaining
+  - `warning`: 30-90 days remaining
+  - `critical`: <30 days remaining
+
+### Caddyfile Configuration
+
+DashCA's Caddyfile block (auto-generated on deployment):
+- **Root**: `C:/caddy/sites/ca`
+- **TLS**: Internal (uses Caddy's local CA)
+- **MIME Types**: Proper headers for .crt, .der, .mobileconfig, .ps1, .sh files
+- **SPA Fallback**: Rewrites non-file requests to /index.html
+- **Cache Control**: Certificates cached for 24h, HTML not cached
+
+### Supported Platforms
+
+- **Windows**: PowerShell installer (installs to LocalMachine\Root store)
+- **macOS**: .mobileconfig profile or command-line installer
+- **Linux**: Shell installer (Debian, RedHat, Arch)
+- **iOS**: .mobileconfig profile (requires manual trust in Settings)
+- **Android**: Direct .crt download (installs as user certificate)
+
+### Landing Page Features
+
+- Automatic OS detection
+- QR code for mobile access
+- Certificate info display (loaded from `/api/ca/info`)
+- Platform-specific installation instructions
+- Copy-to-clipboard for fingerprint and commands
+- Download links for all certificate formats
+
+### Troubleshooting
+
+**Issue**: Certificate fingerprint mismatch during installation
+**Cause**: CA certificate was renewed
+**Solution**: Regenerate certificates and update fingerprints in install scripts
+
+**Issue**: *.sami sites still show warnings after CA install
+**Cause**: Browser may have cached the untrusted state
+**Solution**: Clear browser cache, restart browser, or visit site in incognito mode
+
+**Issue**: iOS doesn't trust certificate after profile install
+**Cause**: iOS requires manual trust enablement
+**Solution**: Settings → General → About → Certificate Trust Settings → Enable trust
+
+## Key Services
+
+| Service | Port | Description |
+|---------|------|-------------|
+| Caddy (HTTPS) | 443 | Reverse proxy |
+| Caddy Admin | 2019 | Caddy API (note: NOT 2021) |
+| DashCaddy API | 3001 | Dashboard backend |
+| DNS2 (Primary) | 100.74.102.61:5380 | Technitium DNS |
+| DNS1 (Secondary) | 192.168.254.204:5380 | Technitium DNS |
+
+## Common Mistakes to Avoid
+
+1. **Wrong services.json**: The API container reads from `C:/caddy/services.json`, not the development copy
+2. **Caddy admin port**: It's 2019, not 2021 (check with `netstat` if unsure)
+3. **DNS server**: DNS2 (100.74.102.61) is PRIMARY, DNS1 is secondary
+4. **Caddyfile not reloaded**: After editing, must POST to /load endpoint or restart Caddy
+
+## Project Info
+
+- **Name**: DashCaddy
+- **Version**: 1.0
+- **Purpose**: Unified management for Docker + Caddy + DNS
+- **Local TLD**: .sami

+# What is DashCaddy?
+
+DashCaddy is a self-hosted web dashboard that unifies Docker container management, Caddy reverse proxy configuration, DNS automation, and SSL certificate provisioning into a single interface. It is designed for homelabbers and self-hosters who want to deploy and manage services without manually editing config files, writing Docker Compose YAML, or configuring DNS records by hand.
+
+You open one page, click "Deploy", pick an app, and DashCaddy handles everything: pulls the Docker image, starts the container, creates a DNS record, adds a reverse proxy block with automatic HTTPS, and registers the service on your dashboard — all in about 30 seconds.
+
+## The Stack
+
+| Layer | Technology | Role |
+|-------|-----------|------|
+| Frontend | Vanilla JS SPA (~12,000 lines across 33 modules) | Dashboard UI, modals, wizards |
+| Backend | Node.js / Express (~20,000 lines across 22 modules + 20 route files) | API server with 125+ endpoints |
+| Reverse Proxy | Caddy | HTTPS termination, internal CA, automatic certificates |
+| DNS | Technitium DNS Server | Automatic A-record creation for `*.sami` domains |
+| Containers | Docker (via dockerode) | Application lifecycle management |
+| Auth | TOTP (RFC 6238) + JWT | Two-factor authentication for dashboard access |
+| Encryption | AES-256-GCM | Credential storage with OS keychain fallback |
+
+The API server runs inside a Docker container (`caddy-api`) on port 3001. Caddy sits in front of everything on port 443, terminating TLS with certificates signed by its own root CA.
+
+## What It Does
+
+### One-Click App Deployment
+
+55 pre-configured templates across 16 categories (Media, Downloads, Productivity, Development, Monitoring, DNS, Security, and more). Each template defines the Docker image, default port, environment variables, volume mounts, health check endpoint, and setup instructions. Deploying an app:
+
+1. Pulls the Docker image
+2. Creates the container with the right env vars, ports, and volumes
+3. Creates a DNS A-record on Technitium (e.g., `plex.sami`)
+4. Adds a reverse proxy block to the Caddyfile with TLS
+5. Reloads Caddy
+6. Registers the service on the dashboard with health monitoring
+
+### Dashboard
+
+Real-time service cards showing status (up/slow/down), response time, uptime percentage, and container ID. Each card has controls to open the service, restart the container, view logs, edit settings, manage auto-login credentials, or delete the service.
+
+Special top-row cards for DNS servers, internet connectivity, TOTP auth status, and the certificate authority.
+
+### Smart Arr Connect
+
+A four-phase wizard that auto-detects Plex, Radarr, Sonarr, Overseerr/Jellyseerr, and Prowlarr, fetches their API keys, and wires them together automatically — connecting Overseerr to Plex, configuring Prowlarr with indexers for Radarr/Sonarr, etc.
+
+### Auto-Login SSO
+
+Per-service credential storage that authenticates users into services transparently via Caddy's `forward_auth` directive. Supports cookie-based auth, JWT-based auth (Open WebUI, Plex), IP-based auth (router), and Emby/Jellyfin token auth with separate device IDs to avoid token invalidation.
+
+### DashCA (Certificate Authority Distribution)
+
+A static site at `ca.sami` that auto-detects the visitor's OS and provides one-click installation of the root CA certificate. Supports Windows (PowerShell), macOS (.mobileconfig), Linux (shell script), iOS (profile), and Android (direct .crt download).
+
+### Monitoring and Operations
+
+- **Health Checker**: Periodic HTTP probes with configurable endpoints per service
+- **Resource Monitor**: Per-container CPU, memory, disk I/O, and network stats
+- **Update Manager**: Checks Docker Hub for newer image versions, one-click updates
+- **Backup/Restore**: Export/import full dashboard configuration as JSON
+- **Audit Logger**: Tracks all administrative actions
+- **Error Log Viewer**: Aggregated error logs with severity filtering
+- **Metrics**: Request counts, response times, error rates, business events (deploys, deletions, DNS records created)
+- **Notifications**: Configurable alerts for health check failures and resource thresholds
+
+### Security
+
+- TOTP two-factor authentication with QR code setup
+- CSRF token protection on all mutating endpoints
+- Helmet security headers
+- Rate limiting (general, strict, TOTP tiers)
+- Input validation and sanitization (via `validator` library)
+- AES-256-GCM credential encryption with OS keychain integration
+- Docker security scanning
+- API key management
+- Non-root container execution with health checks
+
+### Other Features
+
+- Three themes (dark, light, blue)
+- Keyboard shortcuts
+- Customizable logo with position control

+
+## Current State
+
+**Version**: 0.95 (1.0 = public release)
+
+The project is fully functional and in daily use. All core features work. The codebase has a test suite (17 test files under `__tests__/`) covering validators, crypto, health checks, state management, API endpoints, and integration scenarios.
+
+---
+
+## Obstacles to v1.0 Release
+
+### 1. Windows-Only — No Cross-Platform Support
+
+DashCaddy was built on and for Windows. The entire deployment model assumes:
+- `C:/caddy/` as the production path
+- Windows-style path handling throughout (`C:\caddy\Caddyfile`, `host.docker.internal`)
+- Docker Desktop for Windows
+- Windows Task Scheduler for backups
+- PowerShell for CA certificate installation
+
+A Linux or macOS user cannot run this without significant path rewiring. For a public release, either the documentation must clearly state "Windows only" or the path handling needs to be abstracted with platform-aware defaults.
+
+### 2. Hardcoded Infrastructure Assumptions
+
+The codebase has assumptions baked in that only apply to the author's setup:
+
+- **`.sami` TLD**: The local domain suffix is referenced throughout (Caddyfile templates, DNS record creation, documentation). A public user would need their own TLD — this needs to be a first-run configuration option, not a find-and-replace exercise.
+- **Technitium DNS**: DNS automation assumes Technitium's REST API. Users running Pi-hole, CoreDNS, or no local DNS server have no path. The DNS layer needs to be pluggable or clearly documented as a hard requirement.
+- **Docker Desktop**: Container operations assume Docker Desktop's `host.docker.internal` hostname. Native Docker on Linux uses `localhost` differently.
+- **Caddy internal CA**: The TLS model assumes Caddy's built-in PKI. Users wanting Let's Encrypt or other CAs need a different onboarding flow (partially addressed by the "Public Server" setup wizard mode).
+
+### 3. Single-Page HTML Monolith
+
+The frontend is a ~12,000-line single HTML + 33 JS files architecture with no build step, no bundler, no framework, and no component system. While this means zero build tooling to configure, it creates obstacles:
+
+- No minification or tree-shaking — the full payload is served on every load
+- No code splitting — all 33 modules load upfront
+- IIFEs communicate through `window` globals — fragile, hard to test
+- No TypeScript — no compile-time safety on a 12k-line frontend
+- CSS is embedded in the HTML — no style extraction or scoping
+
+This works fine for a personal tool but makes contribution and maintenance harder at scale.
+
+### 4. No Automated Test Coverage for the Frontend
+
+The backend has 17 test files with unit and integration tests. The frontend has zero tests. The dashboard UI is the primary interface users interact with, and it has no test safety net — no unit tests, no E2E tests, no screenshot regression tests.
+
+### 5. No CI/CD Pipeline
+
+There is no GitHub Actions workflow, no pre-commit hooks, no automated linting, and no automated test runs. The deployment process is manual:
+
+1. Edit files in `e:/CaddyCerts/sites/dashcaddy-api/`
+2. Copy JS files to `C:/caddy/sites/dashcaddy-api/`
+3. Run `docker restart caddy-api`
+
+A public project needs at minimum: automated tests on push, a linter, and a documented release process.
+
+### 6. No Installation or Setup Documentation
+
+There is no README explaining how to install DashCaddy from scratch. The `CLAUDE.md` is an internal reference for AI assistants. A new user would need:
+
+- Prerequisites (Docker Desktop, Caddy, Technitium, Node.js)
+- Step-by-step installation guide
+- First-run configuration walkthrough
+- Troubleshooting guide
+- Architecture overview
+
+### 7. Single-User Only
+
+There is no concept of user accounts, roles, or permissions. TOTP protects access but there's one global session. For a household with multiple users, there's no way to give someone read-only access or restrict who can deploy/delete containers.
+
+### 8. No Container Orchestration Beyond Single-Host
+
+DashCaddy manages containers on one Docker host. There's no support for:
+- Docker Compose stacks (multi-container apps like Nextcloud + MariaDB + Redis)
+- Docker Swarm or Kubernetes
+- Remote Docker hosts
+- Container networking (custom networks, inter-container communication)
+
+Apps that need multiple containers (databases, caches, sidecars) must be set up manually.
+
+### 9. Credential and Secret Management Gaps
+
+While credentials are encrypted with AES-256-GCM, the encryption key management has limitations:
+- The master key derivation and storage strategy isn't documented for end users
+- Key rotation exists but there's no scheduled rotation or policy
+- Backup exports include encrypted credentials but the key management for restoring on a different machine isn't clear
+- No integration with external secret managers (Vault, 1Password, etc.)
+
+### 10. Incomplete Template Coverage
+
+55 templates is a strong start, but several popular self-hosted apps are missing, and the template system has constraints:
+- No user-contributed templates or template marketplace
+- No template versioning — if an image tag changes, templates need manual updates
+- No Docker Compose support — templates are single-container only
+- Environment variable templating is basic (`{{PORT}}`, `{{SUBDOMAIN}}`) with no conditional logic
+
+### 11. No Persistent Logging or Metrics Storage
+
+Metrics (request counts, response times, business events) are in-memory only — they reset on container restart. There's no time-series database, no Prometheus endpoint, no Grafana integration. For a monitoring-focused dashboard, losing all metrics on restart is a significant gap.
+
+### 12. The Development/Production File Split
+
+The two-directory development model (`e:/CaddyCerts/sites/` for editing, `C:/caddy/` for production) works for the author but would confuse contributors and can't work as-is for other users. A public release needs a single canonical source of truth with a proper build/deploy pipeline.
+
+---
+
+## What's Strong
+
+Despite these obstacles, DashCaddy has substantial strengths that position it well for release:
+
+- **Feature-complete for its core use case**: Deploy apps, manage reverse proxy, automate DNS — it all works
+- **Security-first design**: TOTP, CSRF, rate limiting, encryption, input validation, non-root containers
+- **Polished UI**: Themes, keyboard shortcuts, onboarding tour, skeleton loaders, responsive design
+- **Smart Arr Connect**: A genuinely useful automation that saves significant manual configuration
+- **Auto-Login SSO**: Handles the messy reality of diverse auth mechanisms (cookies, JWT, IP-based, localStorage)
+- **55 app templates**: Broad coverage of the self-hosting ecosystem
+- **Thread-safe state management**: Proper file locking prevents corruption under concurrent access
+- **In-memory metrics and monitoring**: Even without persistence, the real-time view is useful
+- **Test suite exists**: 17 backend test files covering critical paths
+- **Modular route architecture**: 20 route files keep the 125+ endpoints organized and maintainable
+
+## Summary
+
+DashCaddy is a mature, feature-rich self-hosting dashboard that solves a real problem — the tedium of manually configuring Docker + reverse proxy + DNS for every new service. It's daily-driver stable for a single Windows user with Caddy and Technitium DNS.
+
+The gap between "works great for me" and "anyone can install this" is the remaining 0.05 to v1.0. The biggest obstacles are cross-platform support, installation documentation, and removing the hardcoded infrastructure assumptions. The frontend architecture and CI/CD are secondary concerns that matter more for long-term maintainability than for a functional v1.0 release.

+# DashCA - Certificate Authority Distribution
+
+A self-hosted landing page for distributing your root CA certificate with one-click installation across all major platforms.
+
+## Quick Start
+
+### Regenerate All Certificate Formats
+
+```bash
+cd scripts
+bash generate-all.sh
+```
+
+This will:
+1. Copy root.crt and intermediate.crt from Caddy PKI
+2. Generate root.der (DER format for Windows)
+3. Generate root.mobileconfig (Apple profile for iOS/macOS)
+4. Extract certificate metadata to cert-info.json
+
+### Deploy to Production
+
+```bash
+# Copy all files to production directory
+cp -r e:/CaddyCerts/sites/ca/* C:/caddy/sites/ca/
+```
+
+Or deploy via the dashboard app selector (preferred method).
+
+## File Structure
+
+```

+
+## Development Workflow
+
+1. **Edit Files:** Make changes in `e:/CaddyCerts/sites/ca/`
+2. **Test Locally:** Open `index.html` in browser (file:// protocol works)
+3. **Regenerate Certificates:** Run `scripts/generate-all.sh` if CA renewed
+4. **Deploy:** Copy to production or use dashboard deployment
+5. **Verify:** Visit https://ca.sami and test on target platforms
+
+## Updating After CA Renewal
+
+When Caddy regenerates its CA certificate (every ~10 years):
+
+### 1. Regenerate Certificate Formats
+
+```bash
+cd e:/CaddyCerts/sites/ca/scripts
+bash generate-all.sh
+```
+
+### 2. Update Fingerprints in Scripts
+
+The new fingerprint will be in `cert-info.json`. Update these files:
+
+**install.ps1** (line 17):
+```powershell
+$ExpectedFingerprint = "NEW:FIN:GER:PRINT:HERE"
+```
+
+**install.sh** (line 13):
+```bash
+EXPECTED_FP="NEW:FIN:GER:PRINT:HERE"
+```
+
+### 3. Deploy to Production
+
+```bash
+cp -r e:/CaddyCerts/sites/ca/* C:/caddy/sites/ca/
+```
+
+### 4. Notify Users
+
+- Add banner to dashboard
+- Send notification via configured channels
+- Update documentation with new expiration date
+
+## API Endpoints
+
+DashCA integrates with DashCaddy API:
+
+### GET /api/ca/info
+
+Returns certificate metadata:
+
+```json
+{
+  "success": true,
+  "certificate": {
+    "name": "Sami Home Network Root CA",
+    "fingerprint": "08:98:A5:...",
+    "validFrom": "Feb 12 07:44:51 2025 GMT",
+    "validUntil": "Dec 22 07:44:51 2034 GMT",
+    "daysUntilExpiration": 3235,
+    "algorithm": "ECDSA P-256 with SHA-256",
+    "serialNumber": "c1:dc:48:...",
+    "downloadUrl": "https://ca.sami/root.crt"
+  }
+}
+```
+
+### GET /api/health/ca
+
+Returns CA expiration health status:
+
+```json
+{
+  "status": "healthy",
+  "message": "CA certificate valid for 3235 days",
+  "daysUntilExpiration": 3235,
+  "expiresAt": "Dec 22 07:44:51 2034 GMT"
+}
+```
+
+**Status values:**
+- `healthy`: >90 days remaining
+- `warning`: 30-90 days
+- `critical`: <30 days or expired
+- `error`: Certificate not found or error reading
+
+## Troubleshooting
+
+### Certificate Not Found Error
+
+**Symptom:** Scripts fail with "certificate not found"
+**Cause:** Caddy hasn't generated the local CA yet
+**Solution:** Visit any *.sami domain to trigger CA generation
+
+### Fingerprint Mismatch
+
+**Symptom:** Install scripts reject certificate with fingerprint mismatch
+**Cause:** CA was renewed but scripts not updated
+**Solution:** Run `generate-all.sh` and update fingerprints in install scripts
+
+### iOS Profile Won't Install
+
+**Symptom:** .mobileconfig shows error when installing
+**Cause:** Invalid XML or missing UUIDs
+**Solution:** Regenerate with `node generate-mobileconfig.js`
+
+### Android Shows "Not Trusted"
+
+**Symptom:** Certificate installs but sites still show warnings
+**Cause:** Android installs as "user" certificate; some apps don't trust user CAs
+**Solution:** This is by design. System CA installation requires root access.
+
+### Landing Page Shows "Loading..."
+
+**Symptom:** Certificate info stuck on loading state
+**Cause:** API endpoint not accessible
+**Solution:** Check that dashcaddy-api server is running and `/api/ca/info` responds
+
+## Testing Checklist
+
+Before deploying to production:
+
+- [ ] All certificate formats generated successfully
+- [ ] Landing page loads correctly in browser
+- [ ] OS detection works (test multiple user agents)
+- [ ] QR code renders and scans correctly
+- [ ] Download links work for all file types
+- [ ] API endpoint returns valid certificate info
+- [ ] Copy-to-clipboard buttons work
+- [ ] Platform instruction tabs function correctly
+- [ ] Responsive design works on mobile viewport
+- [ ] HTTPS access works after deployment
+
+## Security Notes
+
+- **Private Key:** NEVER serve the CA private key (`root.key`). Only public certificates are safe to distribute.
+- **Fingerprint Verification:** Install scripts verify fingerprint to prevent MITM attacks
+- **Access Control:** ca.sami should only be accessible on your Tailnet/internal network
+- **HTTPS Enforcement:** The page itself uses HTTPS (via Caddy's internal CA) to protect the distribution
+- **No Auto-Execution:** All installation methods require explicit user action
+
+## Contributing
+
+When adding features to DashCA:
+
+1. Test on multiple platforms before committing
+2. Update this README with new features
+3. Add relevant sections to troubleshooting guide
+4. Update CLAUDE.md if deployment process changes
+5. Ensure backward compatibility with existing certificates
