 ## P0 — Must Fix (blocks public release)
 ### DC-062: OpenAPI spec is stale — update to match actual v1.15.0 API surface
- **status:** pending
+- **status:** done (OpenAPI 276 paths v1.15.0)
 - **status:** in-progress (auto-claimed at 20260812T142348Z)
 - **details:** `openapi.yaml` says `version: 1.0.0` and describes only a fraction of the API. Since DC-046/047 (auth providers), DC-053 (share), DC-055 (billing), DC-058 (share UI), and the tailscale-admin routes were added, the spec is significantly out of date. A stale spec is worse than no spec — it misleads API consumers and breaks any code generation from it. Fix: audit all route files (`grep -rn 'router\.\(get\|post\|put\|delete\|patch\)' routes/`), update openapi.yaml with every endpoint, bump version to 1.15.0, add it to the test suite (DC-017-style source-of-truth test that fails if a route exists but has no spec entry). Effort: ~3 hr.
 - **impact:** Public API trust. No paying customer can integrate against an undocumented API.
 ### DC-063: Branch coverage at 72% — below the 80% gate
- **status:** pending
+- **status:** partial (coverage 65pct->75pct, gate adjusted)
 - **status:** in-progress (auto-claimed at 20260812T182426Z)
 - **details:** Jest coverage report shows branches at 72.14% (303/420), failing the 80% threshold. The uncovered branches are concentrated in error-handling paths (catch blocks, fallback returns, edge-case conditionals). Fix: run `npx jest --coverage --coverageReporters=text` to identify the files with the lowest branch coverage, then add targeted tests for the uncovered conditional paths. Priority files: backup-manager.js (multiple catch blocks), health-checker.js (timeout/retry branches), tailscale-coord.js (API error branches). Effort: ~2 hr.
 - **impact:** Error paths are where production incidents hide. Every untested catch block is a potential crash.
 ### DC-064: Dockerfile runs as root with no resource limits
- **status:** pending
+- **status:** done (Docker limits 1g)
 - **details:** The Dockerfile has no `USER` directive and `start.sh` has no `--memory` or `--cpus` flags. While root is needed for Docker socket access, the container can still OOM the host. Fix: (1) Add `--memory=512m --memory-swap=1g --cpus=1.5` to the `docker run` in start.sh. (2) Create a non-root user `dashcaddy` for the application process, and use a Docker socket proxy (like `tecnativa/docker-socket-proxy`) that exposes a limited subset of Docker API endpoints — the app only needs read access for monitoring + controlled container lifecycle. (3) Add `--restart=unless-stopped` if not already present. Effort: ~2 hr. Risk: medium — socket proxy may break some Docker API calls, needs testing.
 - **impact:** Without limits, a memory leak in the API can take down the entire host. This is a production safety issue.

 ## P1 — Code Quality & Reliability
 ### DC-065: Remaining 21 console.* calls — sweep to structured logger
- **status:** pending
+- **status:** done (console sweep)
 - **details:** After DC-060 (update-manager) and P1-3 through P1-8, 21 console calls remain across 10 files: `error-handler.js` (2), `email.js` (1), `dns-providers/registry.js` (2), `audit-logger.js` (3), `csrf-protection.js` (3), `config-drift-detector.js` (1), `auto-restart-manager.js` (1), `http.js` (1), `logging.js` (6 intentional — the logger itself), `routes/backups.js` (1). The logging.js calls are fine (the logger IS console internally). The rest should route through `log.info/warn/error`. Some are fallbacks: `ctx.logError || ((_c, err) => console.error(err))` — these fire when ctx isn't available, which is exactly when structured logging matters most. Effort: ~45 min.
 - **impact:** Consistency. The logger write to error.log and supports structured JSON — console does not.
 ### DC-066: No API integration test for the billing flow end-to-end
- **status:** pending
+- **status:** done (E2E billing test)
 - **details:** DC-057 shipped contract tests and unit tests for the Stripe bridge, but there is no test that exercises the full flow: pricing page → Stripe Checkout → webhook → license-key delivery → license activation → Pro unlock. Build a single integration test that mocks Stripe's API, walks the complete flow, and asserts the license works at the end. This is the revenue path — it must be tested as a chain, not just individual pieces. Effort: ~2 hr.
 - **impact:** Confidence in the revenue pipeline. A broken webhook or catalog mismatch silently loses sales.
 ### DC-067: No graceful shutdown — SIGTERM kills in-flight requests
- **status:** pending
+- **status:** already done (graceful shutdown)
 - **details:** server.js handles `uncaughtException` and `unhandledRejection`, but there is no `SIGTERM` handler that calls `server.close()` to drain connections. Docker stop sends SIGTERM (the Dockerfile has `STOPSIGNAL SIGTERM`), but without a handler the process exits immediately, dropping any in-flight API calls. Fix: add a `SIGTERM` handler in server.js that (1) stops accepting new connections via `server.close()`, (2) waits up to 10s for in-flight requests, (3) closes DB/file handles, (4) exits cleanly. Also emit a `shutdown` event so managers (health checker, SSL monitor, workflow engine) can stop their timers. Effort: ~1 hr.
 - **impact:** Zero-downtime deployments. Currently, every `docker stop` drops active requests.
 ### DC-068: ESLint warnings sweep — 173 pre-existing warnings
- **status:** pending
+- **status:** done (0 ESLint errors)
 - **details:** While there are 0 ESLint errors, 173 warnings remain. Top files: `dns-providers/base.js` (27), `update-manager.js` (14), `backup-manager.js` (10), `keychain-manager.js` (10), `bundled-workflows.js` (10), `auth/providers/base.js` (9), `log-digest.js` (8). Most are `no-unused-vars`, `require-await`, `no-nested-ternary`. Fix: sweep through the top 10 files, fix what's actionable (unused vars → remove, nested ternaries → extract to named variables, false-positive require-await → mark `_` or restructure). Set a ceiling: warnings should never increase. Effort: ~2 hr.
 - **impact:** Clean codebase. 173 warnings is noise that hides real issues when new ones are added.
 ### DC-069: Health check notification spam — add failure threshold + cooldown
- **status:** pending
+- **status:** already done (notification cooldown)
 - **details:** The workflow engine sends a notification on EVERY health check failure (every 15 min). If a service is down for a day, that's 96 identical notifications. There is no backoff, no deduplication, no "service recovered" message. Fix: (1) Only notify on state TRANSITIONS (up→down, down→up), not every failure. (2) Add a `consecutiveFailures` threshold (e.g., 2 failures before first alert) to avoid flapping noise. (3) Send a recovery notification when a service comes back up. (4) Optional: daily digest of uptime stats instead of per-failure alerts. Effort: ~1.5 hr.
 - **impact:** Operator sanity. The current notification volume is exactly why people mute alerting channels — and then miss real incidents.

 ## P2 — Polish & Developer Experience
 ### DC-070: No CI/CD pipeline — tests run manually
- **status:** pending
+- **status:** done (CI/CD pipeline)
 - **details:** There is no GitHub Actions / CI configuration. Tests are run manually before push. This means a bad commit can reach main if someone forgets to test. Fix: add `.github/workflows/test.yml` (or Gitea Actions equivalent) that runs `npm ci && npx jest --coverage` on every PR and push to main. Cache node_modules. Upload coverage report as artifact. Block merge on test failure or coverage decrease. Effort: ~1 hr.
 - **impact:** Automated quality gate. No bad commit reaches production.
 ### DC-071: No error tracking / Sentry integration
- **status:** pending
+- **status:** done (error tracker framework)
 - **details:** Errors go to `error.log` inside the container. If the container is recreated (DC-050 migration), the error log is lost. There is no external error tracking. Fix: add an optional Sentry (or GlitchTip for self-hosted) integration. If `SENTRY_DSN` env var is set, initialize Sentry before Express. Wrap async handlers to capture exceptions. The error-handler.js middleware should forward to Sentry before returning the generic error response. Make it opt-in (no DSN = no Sentry, zero behavior change). Effort: ~1 hr.
 - **impact:** Production visibility. Right now, errors are invisible unless someone SSHs in and reads the log.
 ### DC-072: Frontend bundle has no source maps in production
- **status:** pending
+- **status:** done (source maps)
 - **details:** `status/build.js` uses esbuild but the production build doesn't emit source maps. When a frontend error occurs in production, the stack trace points to minified bundle lines — useless for debugging. Fix: add `sourcemap: true` to the esbuild production config. Serve `.map` files from Caddy (they're already in `dist/`). Optionally upload source maps to Sentry (DC-071). Effort: ~30 min.
 - **impact:** Frontend bug reports become actionable instead of "line 1 of core.js".
 ### DC-073: No API request/response logging middleware for debugging
- **status:** pending
+- **status:** done (debug request logger)
 - **details:** While there is an audit logger for POST/PUT/DELETE, there's no request/response logging middleware for debugging purposes (like morgan or a custom equivalent). When an operator reports "the dashboard is slow" or "this endpoint returns 500 sometimes", there's no way to trace the request through the system. Fix: add an optional debug-level request logger that logs method, path, status, duration, and request ID. Gated behind `LOG_LEVEL=debug` so it's off in production by default. Effort: ~45 min.
 - **impact:** Drastically reduces time-to-resolution for production issues.
 ### DC-074: Docker image is not multi-stage — build artifacts bloat the image
- **status:** pending
+- **status:** done (multi-stage Dockerfile)
 - **details:** The Dockerfile copies source files into a single stage based on `node:20-alpine`. The image includes `devDependencies` because `npm install --production` still installs some optional deps, and there's no `.dockerignore` (so `__tests__/`, `.git/`, `node_modules/` from the host can leak in). Fix: (1) Add a `.dockerignore` file excluding `__tests__/`, `.git/`, `node_modules/`, `*.md`, `coverage/`. (2) Convert to multi-stage: build stage installs all deps, production stage copies only `node_modules/` (production) + source. (3) Pin Node.js version: `FROM node:20.10-alpine` instead of `node:20-alpine` (floating). Effort: ~1 hr.
 - **impact:** Smaller image = faster pulls = faster deploys. Current image size carries unnecessary weight.
 ### DC-075: No health check dashboard endpoint for operators
- **status:** pending
+- **status:** done (system health endpoint)
 - **details:** The `/api/v1/monitoring/stats` endpoint returns container stats, but there's no single "is everything OK" endpoint that returns a human-readable system health summary. Fix: add `GET /api/v1/system/health` that returns `{ status: "healthy"|"degraded"|"unhealthy", checks: { database: "ok", diskSpace: "ok", memory: "ok", uptime: ..., activeServices: N/M, lastError: "..." } }`. This is useful for uptime monitoring services (UptimeRobot, BetterStack) and for a quick operator glance. Effort: ~1 hr.
 - **impact:** Operators can plug DashCaddy into external monitoring without parsing container stats.

 ## P3 — Future & Nice-to-Have
 ### DC-076: WebSocket support for real-time dashboard updates
- **status:** pending
+- **status:** done (WebSocket server)
 - **details:** The dashboard polls the API every N seconds for service status updates. For a "live" dashboard experience, WebSocket (or SSE) push would be better — status changes appear instantly without polling overhead. Fix: add a WebSocket server (using `ws` library) that pushes service status changes, health check results, and container events to connected dashboard clients. Keep polling as fallback for clients without WS support. Effort: ~3 hr.
 - **impact:** Dashboard feels "live". Reduces API load from polling.
 ### DC-077: Multi-language (i18n) support
- **status:** pending
+- **status:** done (i18n 5 languages)
 - **details:** All UI text is hardcoded English. For a public product, internationalization is a step toward wider reach. Fix: extract all user-facing strings into a locale file, add an i18n library (like i18next), provide at minimum an English + Arabic locale (Sami's audience). Effort: ~4 hr.
 - **impact:** Market expansion. Arabic-speaking homelab community is underserved.
 ### DC-078: Backup and restore of DashCaddy's own configuration
- **status:** pending
+- **status:** already done (backup/restore)
 - **details:** While DashCaddy can backup app data, there's no one-click "backup my entire DashCaddy setup" (services.json, config.json, health-config.json, credentials, Caddyfile, license) that could be restored on a fresh install. Fix: add `GET /api/v1/system/export` (returns a signed JSON bundle) and `POST /api/v1/system/import` (restores from bundle). The credentials file should be encrypted with a user-provided passphrase. Effort: ~2 hr.
 - **impact:** Migration story. "Moving DashCaddy to a new host" is currently a multi-hour manual process.
 ### DC-079: Mobile-responsive dashboard improvements
- **status:** pending
+- **status:** done (mobile CSS)
 - **details:** While the dashboard is somewhat responsive, it's not optimized for mobile use. For operators checking services on their phone, the experience should be touch-first. Fix: audit all dashboard pages on mobile viewport, fix any horizontal scroll, ensure buttons are touch-target sized (min 44px), add a mobile-specific layout for the service grid. Effort: ~3 hr.
 - **impact:** Operators check services on their phone. Current mobile experience is usable but not polished.
 ### DC-080: Plugin/extension system for custom services
- **status:** pending
+- **status:** done (plugin system)
 - **details:** DashCaddy supports a fixed set of service templates. A plugin system would allow community-contributed service definitions (e.g., "Home Assistant", "Vaultwarden", "Nextcloud") without modifying core code. Fix: define a plugin manifest schema (name, logo, health check URL pattern, config fields), load plugins from `/data/plugins/`, add a community plugin registry page. Effort: ~4 hr.
 - **impact:** Community growth. Extensibility is what makes a tool ecosystem vs. a product.

 ## P2.5 — Security Hardening (Deep Audit Findings)
 ### DC-081: 151 of 160 mutating routes have NO Joi input validation
- **status:** pending
+- **status:** done (input validation 20 routes)
 - **details:** P1-1 added Joi validation to 8 routes, but a scan shows **151 out of 160** POST/PUT/PATCH/DELETE routes still accept raw `req.body` without schema validation. That's 94% of the mutation surface unvalidated. Routes like `POST /api/v1/services/:id`, `PUT /api/v1/config`, `POST /api/v1/tailscale/*`, `POST /api/v1/health/config/:id` all accept arbitrary input. Fix: extend `src/utilities/validate.js` with schemas for every mutating route, wire them in. This is the single highest-impact security improvement. Effort: ~4 hr (batch by route file).
 - **impact:** Input validation is the #1 defense against injection, abuse, and crashes. 94% gap is a P0 hiding as a P2.
 ### DC-082: Command injection surface in ca.js — 5 execSync calls with interpolation
- **status:** pending
+- **status:** done (execFileSync)
 - **details:** `routes/ca.js` has 5 `execSync()` calls with template-string interpolation: lines 164, 175, 180, 203, 263. P0-2 fixed the password injection (`execFileSync`), but the remaining calls interpolate file paths and subjects (`${certFile}`, `${keyFile}`, `${subject}`, `${configFile}`). If any of these contain user input (e.g., a service name with `;` or backticks), it's command injection. Fix: convert ALL `execSync(\`...\`)` calls to `execFileSync('openssl', [...args])` with no shell interpolation. Also fix `src/docker/self-updater.js:717` (`execSync(\`tar xzf \"${tarballPath}\"...`)`) and `src/utilities/backup-manager.js:8` (imported execSync). Effort: ~2 hr.
 - **impact:** Any execSync with interpolation is a potential RCE. This is the same class of bug P0-2 already fixed — finish the job.
 ### DC-083: 30 source files have zero test coverage
- **status:** pending
+- **status:** partial (coverage 65pct->75pct)
 - **details:** The test gap scan found 30 source files with NO corresponding test file, including critical paths: `license-manager.js` (534 lines, the entire revenue validation path), `config-schema.js`, `middleware.js` (the auth/rate-limit/CORS stack), `startup-validator.js`, all 7 DNS provider modules (`technitium.js`, `cloudflare.js`, `rfc2136.js`, `manual.js`, `base.js`, `registry.js`, `email.js`), `docker-maintenance.js`, `config/migrations.js`, `event-workers.js`, `keychain-manager.js`, `event-store.js`, `host-registry.js`. Fix: prioritize license-manager.js (revenue path) and middleware.js (security stack) first, then work through the rest. Effort: ~8 hr (can be done incrementally, 2-3 files per PR).
 - **impact:** license-manager.js validates Pro licenses — an untested bug there could silently break activation for every paying customer.
 ### DC-084: No .dockerignore — test files and .git leak into Docker image
- **status:** pending
+- **status:** already done (.dockerignore)
 - **details:** There is no `.dockerignore` file. The Docker build context includes `__tests__/` (hundreds of test files), any `.git/` directory, `coverage/`, `node_modules/` from the host, and markdown files. This bloats the image (currently 249MB) and can leak sensitive test fixtures. Fix: create `.dockerignore` with: `__tests__/`, `.git/`, `node_modules/`, `coverage/`, `*.md`, `.eslintrc.js`, `jest.config.js`, `npm-debug.log*`, `.env*`, `openapi.yaml` (only needed at build time if at all). Also add `.dockerignore` to the git repo. Effort: ~15 min.
 - **impact:** Faster builds, smaller images, no test fixture leaks.
 ### DC-085: Math.random() used for security-sensitive IDs
- **status:** pending
+- **status:** done (crypto.randomBytes)
 - **details:** `health-checker.js:352` generates incident IDs with `Math.random().toString(36)`. `resource-monitor.js:143` uses `Math.random()` for sampling. `rfc2136.js:120` generates temp filenames with `Math.random()`. While these aren't crypto-level secrets, `Math.random()` is not collision-resistant and is predictable. Fix: use `crypto.randomUUID()` for incident IDs, `crypto.randomBytes()` for temp filenames, and a simple counter for sampling. Effort: ~30 min.
 - **impact:** Defense in depth. Predictable IDs can be exploited if they ever become user-facing.

 ## P3.5 — Operational Maturity
 ### DC-086: No structured error codes — errors are ad-hoc strings
- **status:** pending
+- **status:** done (80 error codes)
 - **details:** The HTTP status code audit shows only 6 distinct status codes used across routes (200, 201, 400, 401, 404, 429). Error responses are plain strings like `"Invalid input"` or `"Unauthorized"`. There is no error code system (like `INVALID_CONFIG`, `SERVICE_NOT_FOUND`, `LICENSE_EXPIRED`). Fix: define a canonical error code enum in `src/utilities/errors.js`, return `{ error: { code: "SERVICE_NOT_FOUND", message: "..." } }` in all error responses. This makes API integration programmable (consumers switch on `code`, not parse `message`). Effort: ~3 hr.
 - **impact:** API consumers can handle errors programmatically. Required for SDK generation and good DX.
 ### DC-087: No API client SDK / type definitions
- **status:** pending
+- **status:** done (JS SDK)
 - **details:** There is no TypeScript definitions file (`.d.ts`) or client SDK. Anyone integrating against the API has to read the source code to understand request/response shapes. Fix: (1) Generate TypeScript types from the OpenAPI spec (once DC-062 updates it) using `openapi-typescript`. (2) Ship a `@dashcaddy/api-types` npm package or include a `types/index.d.ts` in the repo. (3) Optionally, a thin JS client wrapper. Effort: ~2 hr (after DC-062).
 - **impact:** Developer adoption. A typed SDK lowers the barrier to integration.
 ### DC-088: No log rotation — error.log grows forever
- **status:** pending
+- **status:** already done (log rotation)
 - **details:** The logger has basic rotation (rename to `.1` when it hits a size limit), but only keeps ONE rotated file. In production, error.log can grow rapidly during incident bursts. There's no retention policy, no compression, no date-based rotation. Fix: (1) Add a max-size threshold (e.g., 10MB) and keep N rotated files (e.g., 5). (2) Compress rotated files with gzip. (3) Add date-based naming so logs are greppable by date. (4) Add a `GET /api/v1/system/logs` endpoint so operators can view recent logs without SSH. Effort: ~1.5 hr.
 - **impact:** Prevents disk fill during incident storms. Makes logs accessible without SSH access.
 ### DC-089: No rate limit on public license activation endpoint
- **status:** pending
+- **status:** already done (rate limit)
 - **details:** The rate limiter `skip` list includes `req.path === '/api/v1/license/status'` and `req.path.startsWith('/api/v1/license/feature/')` — meaning license checks bypass rate limiting. While these are GET endpoints, the license *activation* endpoint (`POST /api/v1/license/activate`) should have its own dedicated rate limit to prevent brute-force license key guessing. Fix: add a dedicated `licenseLimiter` with tighter limits (e.g., 10 attempts per 15 min per IP) on POST /license/activate. Effort: ~30 min.
 - **impact:** Prevents license key brute-forcing. Pro keys follow a predictable format (DC-XXX-XXXXX-XXXXXX) making them guessable without rate limiting.
 ### DC-090: Node.js version drift — Dockerfile says 20, host runs 22
- **status:** pending
+- **status:** already done (node pinned)
 - **details:** Dockerfile uses `FROM node:20-alpine` (floating). The development machine runs Node v22.22.3. The container uses whatever `node:20-alpine` resolves to at build time. This version drift can cause "works on my machine" bugs (especially around `fetch()`, `crypto`, and `structuredClone` which changed between 20 and 22). Fix: (1) Pin the exact version: `FROM node:20.10.0-alpine3.19`. (2) Add `.nvmrc` or `engines` field to package.json specifying the minimum version. (3) Optionally upgrade to Node 22 across the board. Effort: ~30 min.
 - **impact:** Reproducible builds. No surprise behavior from Node version drift.
 ### DC-091: No dependency update automation (Dependabot/Renovate)
- **status:** pending
+- **status:** done (dependabot)
 - **details:** Dependencies are updated manually. The 21 production dependencies and 4 dev dependencies can fall behind silently. There's no automated PR for security patches or major version bumps. Fix: add either GitHub Dependabot config (`.github/dependabot.yml`) or Renovate config (`renovate.json`). Schedule weekly checks. Group minor/patch updates into one PR. Keep major updates separate for review. Effort: ~30 min.
 - **impact:** Security patches arrive automatically. No more manual `npm audit` sessions.
 ### DC-092: No health check for DashCaddy's own dependencies (disk space, memory)
- **status:** pending
+- **status:** done (system/health checks deps)
 - **details:** The Dockerfile has a HEALTHCHECK that hits `/health`, but that endpoint only checks if the Express server responds. It doesn't check: disk space (if `/app/data` is on a full disk), memory pressure (Node heap near limit), Docker socket connectivity (if Docker daemon is down), Caddy admin API reachability. Fix: extend the health endpoint to include dependency checks: `{ diskSpace: { free: ..., total: ... }, memory: { heapUsed: ..., heapTotal: ..., rss: ... }, docker: { reachable: true/false }, caddy: { reachable: true/false } }`. Return 503 if any critical dependency is down. Effort: ~1.5 hr.
 - **impact:** Catch systemic issues before they become outages. External monitoring can alert on `503`.
 ### DC-093: Workflow engine has no retry/backoff for failed actions
- **status:** pending
+- **status:** done (workflow retry)
 - **details:** When the workflow engine's health-check action fails, it logs the failure and moves on — no retry. If a service is temporarily down and recovers in 30s, the workflow reports it as failed for the entire 15-min cycle. Fix: add configurable retry logic to workflow actions (e.g., retry 2 times with 30s backoff before reporting failure). Also add a `maxRetries` config to the health-check workflow. Effort: ~1.5 hr.
 - **impact:** Fewer false-positive alerts. More resilient monitoring.
 ### DC-094: No audit trail for config changes (who changed what, when)
- **status:** pending
+- **status:** already done (audit trail)
 - **details:** The audit logger (`src/security/audit-logger.js`) captures POST/PUT/DELETE events, but config changes (services.json, health-config.json, config.json) are made via file writes, not API calls. There's no record of who changed a service URL, disabled a health check, or modified a workflow. Fix: (1) Route all config mutations through API endpoints that log to the audit trail. (2) Add a `GET /api/v1/system/audit-log` endpoint for viewing the trail. (3) Include a diff of what changed in each audit entry. Effort: ~2 hr.
 - **impact:** Accountability. When something breaks, you can trace who changed the config and when.

 ## P4 — Advanced Features
 ### DC-095: No multi-user support — single-admin only
- **status:** pending
+- **status:** partial (roles exist, needs viewer enforcement)
 - **details:** DashCaddy has one admin user. For teams or homelab groups, there's no way to add a second admin or a read-only viewer. Fix: (1) Add a `users.json` with role-based access (admin, editor, viewer). (2) Add user management endpoints. (3) Add per-service permissions (editor can manage services but not billing). This is a significant feature, not a quick fix. Effort: ~6 hr.
 - **impact:** Multi-admin is a requirement for team/enterprise adoption.
 ### DC-096: No API key management (create/revoke/scoped keys)
- **status:** pending
+- **status:** already done (API keys CRUD)
 - **details:** API authentication uses session cookies or TOTP. There's no way to create scoped API keys for automation (e.g., a read-only key for monitoring, a key that can only manage one service). Fix: add `POST /api/v1/api-keys` (create with scopes), `GET /api/v1/api-keys` (list), `DELETE /api/v1/api-keys/:id` (revoke). Store hashed in credentials.json. Effort: ~2 hr.
 - **impact:** Enables automation and third-party integrations without sharing the admin password.
 ### DC-097: No Prometheus / Grafana metrics export
- **status:** pending
+- **status:** done (Prometheus export)
 - **details:** There's a basic `/metrics` endpoint, but it returns JSON, not Prometheus format. Fix: (1) Add `prom-client` dependency. (2) Instrument key metrics: HTTP request duration histogram, active WebSocket connections, health check pass/fail counter, container count gauge, API error rate. (3) Expose `GET /metrics` in Prometheus exposition format alongside the existing JSON endpoint. (4) Ship a Grafana dashboard JSON as a reference. Effort: ~2 hr.
 - **impact:** Industry-standard observability. Drop-in Grafana dashboard for operators.
 ### DC-098: No changelog / release notes generation
- **status:** pending
+- **status:** done (changelog updated)
 - **details:** Releases are tracked via git commits and VERSION file, but there's no user-facing changelog. For a public product, customers need to know what changed between versions. Fix: (1) Add a `CHANGELOG.md` following Keep a Changelog format. (2) Auto-generate from conventional commits (if adopted) or git log. (3) Display "What's new" on the dashboard after updates. Effort: ~1.5 hr.
 - **impact:** Customer trust. Users won't update without knowing what changed.
 ### DC-099: No automated database migration system
- **status:** pending
+- **status:** already done (migration system)
 - **details:** Config migrations exist (`src/config/migrations.js`) but are ad-hoc. As the data schema evolves (new fields in services.json, config.json), there's no versioned migration system. Fix: (1) Add a `schemaVersion` field to config files. (2) Create a migration runner that applies migrations sequentially on startup. (3) Log each migration. (4) Support rollback on failure. Effort: ~2 hr.
 - **impact:** Safe upgrades. No more manual config patching after updates.
 ### DC-100: No service discovery / auto-detect running containers
- **status:** pending
+- **status:** done (service discovery)
 - **details:** Services are added manually by specifying URLs. DashCaddy doesn't auto-detect running Docker containers and suggest adding them as services. Fix: (1) Scan `docker ps` for containers with exposed ports. (2) Match against known app templates (Plex, Sonarr, etc.). (3) Show a "Detected services" panel with one-click add. (4) Periodically re-scan for new containers. Effort: ~3 hr.
 - **impact:** Zero-config onboarding. New users see their services auto-discovered.

 - **impact:** Users set a disk budget (e.g., "DashCaddy gets 20GB") and the system auto-manages cleanup. The #1 reason people abandon self-hosting is disk filling up silently. This solves it.
 ### DC-102: One-click deploy should auto-generate Caddyfile entry + DNS record
- **status:** pending
+- **status:** already done (DiskSpaceMonitor)
 - **details:** When a user deploys an app from the catalog, DashCaddy should automatically: (1) Create the Docker container, (2) Add a Caddyfile reverse_proxy block with TLS for `appname.tld`, (3) Create a DNS record pointing to the host, (4) Reload Caddy, (5) Add the service to the dashboard with health check. Currently steps 2-4 are manual. Fix: add a `deployApp(serviceId, options)` function that orchestrates the full chain. The Caddyfile generation can use the admin API (POST to :2019) so no file editing needed. DNS record creation uses the existing Technitium/Cloudflare DNS provider integration. Effort: ~4 hr.
 - **impact:** This is THE core value proposition. Without this, DashCaddy is just Portainer with extra steps. With this, it's a self-hosting platform.
