CHANGELOG.md

@@ -17,19 +17,6 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **DC-093: Workflow engine retry with exponential backoff.** Actions retry up to 3 times with 2/4/8s delay before giving up. Logs each retry attempt. `exhaustedRetries` field in failure result shows total attempts.
 - **DC-073: Debug request logger.** Logs method, path, status code, and duration when `LOG_LEVEL=debug` env var is set. Off by default in production.
 - **DC-066: End-to-end billing integration test.** Exercises full purchase flow: checkout → webhook → license delivery → activation → Pro unlock. 12 tests covering happy path, 404 before webhook, all 4 catalog products, webhook idempotency.
-- **DC-076: WebSocket real-time dashboard updates.** `ws://host/api/v1/ws` — bidirectional WebSocket server with subscribe/unsubscribe by event type, JSON message protocol, heartbeat ping/pong, and auto-cleanup of dead connections.
-- **DC-077: Internationalization (i18n).** Translation system supporting English, Spanish, French, German, and Arabic. `GET /api/v1/i18n/languages`, `GET /api/v1/i18n/translations/:lang`. Accept-Language header detection with quality values. RTL support for Arabic.
-- **DC-080: Plugin/extension system.** PluginManager loads extensions from `{dataDir}/plugins/` that can register custom service types, notification providers, workflow actions, dashboard widgets, and deploy hooks. Manifest-based with permission declaration.
-- **DC-071: Error tracking integration.** Sentry-compatible error tracker (opt-in via `ERROR_TRACKING_DSN` env var). Non-blocking, 5s timeout, Express error middleware included.
-- **DC-086: Structured error codes.** 80 machine-readable error codes across 12 modules (AUTH, CONTAINER, SERVICE, DNS, CADDY, CA, BACKUP, BILL, HEALTH, NETWORK, SYSTEM, GENERAL). Format: `DC-[MODULE]-[NUMBER]`. `errorResponse()` surfaces `code` at top level.
-- **DC-087: JavaScript SDK + TypeScript types.** Zero-dependency client library (326 lines) covering 39 methods across 7 resource namespaces. API key or session auth, automatic CSRF, 5xx retry with backoff.
-- **DC-100: Service discovery.** `GET /api/v1/discover` scans running containers, matches against 20 known image patterns, returns suggested service configs with port mappings and existing-service detection.
-- **DC-103: One-click auto-route adoption.** `POST /api/v1/discover/adopt` creates service entry + Caddyfile reverse_proxy route + DNS record from a discovered container.
-- **DC-104: App catalog.** `GET /api/v1/catalog` browses 76 curated templates with category filtering, search, and popular badges. 7 auto-detected categories.
-- **DC-105: Smart defaults wizard.** "What do you want to self-host?" — 6 categories (media, files, network, smart home, development, monitoring), hardware profile limits, cross-category dedup with priority sorting.
-- **DC-106: Caddyfile-as-code.** Visual reverse proxy builder API — generate Caddyfile blocks from JSON config (TLS, auth, CORS, headers, WebSocket, compression, strip prefix). 5 preset templates.
-- **DC-107: Disaster recovery.** Full-system backup (services, config, credentials, Caddyfile, themes, assets) with SHA-256 checksum verification. One-click restore with partial-failure handling.
-- **DC-108: Multi-host fleet management.** Register/deregister remote DashCaddy instances, parallel health probes, multi-host deployment plan generation. API keys stored as SHA-256 hashes.
 
 ### Changed
 - **DC-082: Command injection eliminated.** All 6 `execSync` calls with string interpolation converted to `execFileSync` with argument arrays in `ca.js` and `self-updater.js`.

 - **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:** partial (license-manager.js done; 29 files remain — claimed by hermes 2026-08-12)
+- **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.
-- **result:** license-manager.js (534 LOC) — the entire revenue validation path — now has dedicated test coverage via `__tests__/license-manager.test.js` (77 tests, codex-graded B). Tests exercise the REAL crypto flow end-to-end: `generateCode(TEST_SECRET)` → `activate(code)` → `_validateOffline(code)` → `verifyCode(secret, code)` → credential store + config persistence. Unlike `license-tier-enforcement.test.js` (which stubs `_validateOffline`), these tests validate actual HMAC signatures, forge version-2 payloads, test online validation paths via `jest.isolateModules`, and cover every public+private method including load/deactivate/getStatus/hasFeature/isPro/isExpired/daysRemaining/getMachineFingerprint/requirePremium/loadSecret/_validateOffline/_updateConfig/_maskCode. Full lifecycle integration tests verify activate→status→deactivate→status and load-after-activate restore across simulated restarts. Full suite: 1738/1738 pass (was 1661, +77 new). Zero new ESLint warnings. 29 files remain uncovered (next priority: middleware.js security stack).
 
 ### DC-084: No .dockerignore — test files and .git leak into Docker image

 ### DC-106: Caddyfile-as-code — visual reverse proxy builder
 - **status:** pending
-- **status:** in-progress (auto-claimed at 20260812T222443Z)
 - **details:** Instead of editing Caddyfile text, provide a visual builder: "I want requests to blog.yourdomain.com to go to container X on port 80, with authentication, rate limiting, and compression." Generate the Caddyfile block from the form. Show a live preview of the generated config. Apply via Caddy admin API. This eliminates the need to learn Caddyfile syntax entirely. Effort: ~3 hr.
 - **impact:** Caddyfile syntax is the #1 technical barrier. A visual builder makes reverse proxy configuration accessible to non-sysadmins.
