+# Changelog
+
+All notable changes to this project will be documented in this file.
+Format follows [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+---
+
+## [1.2.1] - 2026-05-17
+
+### Added
+
+- **Version footer** — the dashboard footer now displays the running app version (e.g. `sofarr v1.2.1`), fetched from the `/health` endpoint on page load.
+
+---
+
+## [1.2.0] - 2025-05-17
+
+### Security
+
+- **Docker secrets support** — all sensitive environment variables (`COOKIE_SECRET`, `EMBY_API_KEY`, `SABNZBD_API_KEY`, `SONARR_API_KEY`, `RADARR_API_KEY`, `QBITTORRENT_PASSWORD`) now support the standard `_FILE` variant for loading values from mounted secret files (e.g. `COOKIE_SECRET_FILE=/run/secrets/cookie_secret`).
+- **Weak secret warning** — server now warns at startup if `COOKIE_SECRET` is shorter than 32 characters.
+- **EMBY_URL validation** — validates the Emby URL scheme at startup and warns on misconfiguration.
+- **Improved error sanitization** — `sanitizeError()` now also redacts hostnames from full request URLs that may appear in axios error messages.
+- **Graceful shutdown** — `SIGTERM` and `SIGINT` handlers now stop the background poller and drain open HTTP connections before exiting. Prevents data loss and zombie processes on `docker stop`.
+
+### Compliance
+
+- **MIT LICENSE file** added to project root.
+- **Copyright headers** added to key server source files (`index.js`, `poller.js`, `config.js`, `sanitizeError.js`, `loadSecrets.js`).
+- **`security.txt`** (`/.well-known/security.txt`) added for responsible disclosure.
+
+### Configuration
+
+- **URL validation** added to `config.js` — all configured service instance URLs are validated for scheme (`http`/`https`) and well-formedness at startup; malformed URLs emit a warning instead of crashing.
+
+### Docker / Deployment
+
+- **`docker-compose.yaml`** updated with commented Option B (Docker secrets `_FILE` pattern) alongside the existing plain-env Option A.
+- **`.dockerignore`** updated — `tests/`, `coverage/`, `vitest.config.js`, `CHANGELOG.md`, `SECURITY.md`, `LICENSE`, `.markdownlint.json` excluded from the production image.
+
+### CI
+
+- **`docs-check` workflow** added — separate Gitea Actions workflow that lints all Markdown files and validates Mermaid diagram syntax on every push that touches `.md` files. Both jobs use `continue-on-error: true` so documentation issues never block a release.
+- **Mermaid diagrams** in `docs/ARCHITECTURE.md` fixed — replaced invalid `\n` in stateDiagram transition labels, Unicode arrows/dashes, and double-spaces in flowchart edge definitions.
+
+---
+
+## [1.1.2] - 2025-05-15
+
+### Changed
+
+- Server startup message now includes the current version (`sofarr v1.1.2`).
+
+---
+
+## [1.1.1] - 2025-05-14
+
+### Fixed
+
+- Docker/TrueNAS SCALE healthcheck: dynamic HTTP/HTTPS selection based on `TLS_ENABLED` environment variable. Prevents containers from being stuck in "starting" state when `TLS_ENABLED=false`.
+
+---
+
+## [1.1.0] - 2025-05-13
+
+### Added
+
+- **Episode display** — TV show download cards now show episode information (S01E01 format with title). Multi-episode packs show a "Multiple episodes" badge with a tooltip listing all episodes.
+- **Episode tooltip** — solid background colour (theme-dependent) for readability.
+- Sonarr queue and history API requests now include `includeEpisode=true`.
+
+---
+
+## [1.0.0] - 2025-05-01
+
+### Added
+
+- Initial release.
+- SABnzbd queue and history integration.
+- qBittorrent torrent integration.
+- Sonarr and Radarr queue/history matching with user tag filtering.
+- Emby/Jellyfin authentication.
+- Server-Sent Events (SSE) real-time dashboard.
+- Per-request CSP nonce, CSRF double-submit, HSTS, Permissions-Policy.
+- Background polling with configurable interval and on-demand fallback.
+- Docker multi-stage build, non-root user, read-only filesystem.
+- TLS support with bundled snakeoil certificate.

+
+## Threat Model
+
+sofarr is a personal dashboard intended for a small trusted group (household/team).
+It proxies requests to *arr stack services using stored API keys and authenticates
+users via Emby. The primary threat surface when exposed to the public internet:
+
+| Threat | Mitigations |
+|--------|-------------|
+| Credential brute-force | Rate limiting (10 fails/15 min per IP), account lockout window |
+| Session hijacking | HMAC-signed cookies, `httpOnly`, `secure`, `sameSite=strict`, short TTL |
+| CSRF | Double-submit cookie pattern (`X-CSRF-Token` header required on all mutations) |
+| API key leakage via errors | `sanitizeError()` redacts keys/tokens from all error responses and logs |
+| Token theft after logout | Server-side token store; Emby token revoked on logout |
+| XSS → token theft | `httpOnly` cookies; CSP with per-request nonce blocks inline injection |
+| Clickjacking | `X-Frame-Options: DENY` + CSP `frame-ancestors 'none'` |
+| Info disclosure via headers | Helmet v7 removes `X-Powered-By`, sets `noSniff`, `xssFilter`, etc. |
+| Privilege escalation (container) | Non-root user (UID 1000), `no-new-privileges`, all caps dropped |
+| Unbounded log growth | Size-based rotation: 10 MB cap, 3 rotated files kept |
+| Dependency vulnerabilities | `npm audit --audit-level=high` in CI on every push |
+
+---
+
+## Production Deployment Checklist
+
+### Required
+
+- [ ] `COOKIE_SECRET` set to a random 32-byte hex string (`openssl rand -hex 32`)
+- [ ] `NODE_ENV=production`
+- [ ] `TRUST_PROXY=1` set if behind a reverse proxy
+- [ ] sofarr bound to `127.0.0.1` only (not `0.0.0.0`) — expose via proxy
+- [ ] HTTPS enforced by the reverse proxy with a valid certificate
+- [ ] Firewall rules: only 443/80 open externally; 3001 not directly exposed
+
+### Recommended
+
+- [ ] Reverse proxy: Nginx, Caddy, or Traefik with TLS termination
+- [ ] Set `Strict-Transport-Security` at proxy level (sofarr also sends HSTS)
+- [ ] `DATA_DIR` on a named Docker volume (not bind-mounted to sensitive host path)
+- [ ] Rotate `COOKIE_SECRET` periodically (causes all users to re-login)
+- [ ] Enable Docker's `--read-only` flag (already in `docker-compose.yaml`)
+- [ ] Monitor `/health` endpoint with an uptime checker
+
+### Docker Secrets (alternative to env vars)
+
+For production environments that support Docker secrets, you can mount secret
+files and reference them:
+
+```yaml
+secrets:
+  cookie_secret:
+    file: ./secrets/cookie_secret.txt
+  emby_api_key:
+    file: ./secrets/emby_api_key.txt
+
+services:
+  sofarr:
+    secrets:
+      - cookie_secret
+      - emby_api_key
+    environment:
+      - COOKIE_SECRET_FILE=/run/secrets/cookie_secret
+      - EMBY_API_KEY_FILE=/run/secrets/emby_api_key
+```
+
+> Since v1.2.0, sofarr natively supports the `_FILE` pattern.
+> Set `COOKIE_SECRET_FILE=/run/secrets/cookie_secret` and sofarr will
+> read the secret value from that file at startup. See `docker-compose.yaml`
+> for a complete example.
+
+---
+
+## Reverse Proxy Example (Caddy)
+
+```caddy
+sofarr.example.com {
+    reverse_proxy localhost:3001
+    header {
+        Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
+        X-Robots-Tag "noindex, nofollow"
+    }
+}
+```
+
+## Reverse Proxy Example (Nginx)
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name sofarr.example.com;
+
+    ssl_certificate     /etc/letsencrypt/live/sofarr.example.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/sofarr.example.com/privkey.pem;
+
+    location / {
+        proxy_pass http://127.0.0.1:3001;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+
+        # Required for SSE (Server-Sent Events) — disable response buffering
+        proxy_buffering off;
+        proxy_cache off;
+        proxy_read_timeout 3600s;
+    }
+}
+```
+
+---
+
+## Security Headers (emitted by sofarr)
+
+| Header | Value |
+|--------|-------|
+| `Content-Security-Policy` | `default-src 'self'; script-src 'self' 'nonce-…'; style-src 'self' 'nonce-…'; style-src-attr 'unsafe-inline'; img-src 'self' data: blob:; object-src 'none'; frame-ancestors 'none'` |
+| `Strict-Transport-Security` | `max-age=31536000; includeSubDomains; preload` (production only) |
+| `X-Content-Type-Options` | `nosniff` |
+| `X-Frame-Options` | `DENY` |
+| `Referrer-Policy` | `strict-origin-when-cross-origin` |
+| `Permissions-Policy` | `camera=(), microphone=(), geolocation=(), payment=(), usb=()` |
+
+---
+
+## Rate Limits
+
+| Endpoint | Limit |
+|----------|-------|
+| `POST /api/auth/login` | 10 failed attempts per 15 min per IP |
+| All `/api/*` routes | 300 requests per 15 min per IP |
+
+---
+
+## Supply Chain
+
+- All dependencies pinned to minor version ranges in `package.json`
+- `npm audit --audit-level=high` runs in CI on every push and pull request
+- `npm audit fix` should be run when vulnerabilities are reported

+
+## Key design decisions
+
+- **`server/app.js`** — Express factory extracted from `server/index.js`. Tests import `createApp()` without triggering the log-file setup, `process.exit()` calls, or background poller in the entry point.
+- **nock over `vi.mock('axios')`** — Vitest's `vi.mock` only intercepts ESM `import` statements. Since `auth.js` uses CJS `require('axios')`, nock (which patches Node's `http`/`https` modules) is the correct tool for intercepting outbound requests.
+- **`SKIP_RATE_LIMIT=1`** — All supertest requests originate from `127.0.0.1`, which would quickly exhaust per-IP rate-limit windows. Setting this env var raises the limits to `Number.MAX_SAFE_INTEGER` in both the API limiter and the login limiter.
+- **Isolated `DATA_DIR`** — Each test worker gets a unique temp directory so `tokenStore.js` file I/O never conflicts with a running dev server.
+- **`createApp({ skipRateLimits: true })`** — The app factory accepts an option to disable the general API rate limiter in addition to the env var for the login-specific limiter.
+
+## Coverage targets
+
+The tested files meet these per-file minimums (enforced in CI):
+
+| File | Lines | Branches |
+|---|---|---|
+| `server/app.js` | 85% | 65% |
+| `server/routes/auth.js` | 85% | 70% |
+| `server/middleware/requireAuth.js` | 75% | 80% |
+| `server/utils/sanitizeError.js` | 60% | — |
+| `server/utils/config.js` | 50% | 55% |
+
+`dashboard.js` and `poller.js` are large files requiring complex external-service mocks (Sonarr, Radarr, qBittorrent, Emby) and are tracked as future test coverage work.
