[grade=A] AI Intent Router — natural language → structured actions

POST /api/v1/ai/intent takes natural language and returns structured intent:
- 'Deploy Plex' → { intent: deploy, appId: plex, deployPlan }
- 'I want to stream movies' → { intent: recommend, categories: [media-streaming] }
- 'Why is Plex down?' → { intent: diagnose, serviceId: plex }
- 'Back up everything' → { intent: backup }
- 'Is everything OK?' → { intent: health }

GET /api/v1/ai/capabilities returns self-describing capabilities for agent discovery.

Pattern-based matching works offline (no LLM call needed). LLM_PROXY_URL env
var can be set for complex query delegation.

18 intent tests covering deploy, recommend, diagnose, backup, health, list,
and unknown intents. 1770 total tests pass.

+# DashCaddy AI-Native Vision
+
+## The Vision
+DashCaddy should be inherently optimized for AI agents to control it.
+Users should be able to self-host anything using natural language.
+
+## Core Principles
+1. **AI as first-class citizen** — not a bolt-on chatbot, but where the API itself is designed for AI consumption
+2. **Natural language → deployment** — "host a Plex server" → running container + reverse proxy + DNS + health check
+3. **Agent-friendly API** — structured responses, semantic error codes, state machines, idempotent operations
+4. **MCP-native** — DashCaddy should expose itself as an MCP server so any AI agent can control it
+
+## Architecture Layers
+
+### Layer 1: Natural Language Intent Router (NEW)
+`POST /api/v1/ai/intent` — Takes natural language, returns structured action plan
+- "I want to stream movies" → { category: media-streaming, recommended: [plex, sonarr, radarr] }
+- "Set up a password manager" → { category: file-sync, recommended: [vaultwarden] }
+- "Block ads on my network" → { category: home-network, recommended: [adguard] }
+- "Why is Plex down?" → diagnostics query → { action: health-check, service: plex }
+
+### Layer 2: MCP Server (NEW)
+Expose DashCaddy as a Model Context Protocol server so ANY AI agent (Claude, GPT, Gemini, Hermes) can:
+- List services, containers, health status
+- Deploy/stop/restart apps
+- Manage DNS records and Caddyfile routes
+- Run diagnostics and get structured results
+- Create backups and restore
+
+### Layer 3: Structured Action API (EXISTING — needs enhancement)
+366 existing routes already cover the CRUD surface. Enhancement needed:
+- Consistent response envelopes (already have `ok()` / `errorResponse()`)
+- All error responses include machine-readable codes (DC-086 done — 80 codes)
+- Idempotency keys for mutating operations
+- Operation receipts (UUID + status tracking)
+
+### Layer 4: Semantic Service Catalog (EXISTING — DC-104)
+76 templates with categories, auto-categorization, search.
+Enhancement: Add intent tags ("movie streaming", "password manager", "ad blocking")
+
+### Layer 5: Diagnostic Engine (NEW)
+`POST /api/v1/ai/diagnose` — Structured troubleshooting
+- "Why is X slow?" → checks: CPU, memory, network, disk I/O, container logs
+- Returns structured findings with severity + suggested fix
+- Can auto-apply fixes with user approval
+
+### Layer 6: Deployment Orchestrator (PARTIAL — DC-103 + wizard)
+"Deploy Plex" → full automation chain:
+1. Pull image
+2. Create container with optimal config
+3. Generate Caddyfile route (DC-106)
+4. Create DNS record
+5. Add to services list
+6. Start health monitoring
+7. Configure notifications
+8. Return ready-to-use URL

 ### DC-083: 30 source files have zero test coverage
-- **status:** partial (coverage 65pct->75pct)
+- **status:** partial (license-manager.js done; 29 files remain — claimed by hermes 2026-08-12)
 - **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-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.
