Judge r2 (grade C) — all 3 blockers + both polish items:
1. REQUEST-vs-NOTIFICATION by PRESENCE, never truthiness: validateJsonRpc
uses hasOwnProperty('id'); id 0 and id '' are VALID request ids echoed
back BY VALUE (strict-equality tested), id:null treated as a request
under the documented error-id convention. mcp-core default branch fixed
the same way (`if (id)` → hasOwnProperty — id 0 / '' unknown-method now
answer -32601 with the id echoed instead of being swallowed as falsy).
Routes' malformed-notification silence path also switched to
presence-based detection (id:null + bad params → 400 envelope, not 204).
2. params:null REJECTED (-32600): contract is object-or-omitted ONLY
(strict JSON-RPC; the old code's m.params !== null guard contradicted
the documented contract). Boundary tests pin the policy.
3. Unknown-method boundary tests: id 0 → -32601 id:0, id '' → -32601 id:'',
id null → -32601 id:null — asserted at BOTH layer levels (route).
Polish:
- 16-case TABLE-DRIVEN boundary matrix covering every allowed/rejected
id/params combination incl. 202 vs 204 notification split.
- Verifier now probes writable /tmp up front (exit 73 + clear message if
unavailable; documented requirement) instead of dying at mktemp.
- Verifier target count 57 → 73 (DC-162 suites) with the boundary table
named in the assertion label.
Full DC-162 suite: 73 passed (route 50 + core 23). No transport/credential
semantics changed from rev2.

DashCaddy is now controllable by ANY AI agent via Model Context Protocol.
17 MCP tools exposed:
- Service management: list, get, health check
- Container management: list, start/stop/restart/remove
- Deployment: deploy app, wizard recommendations, catalog search, discovery
- System: health, metrics, diagnostics
- Infrastructure: DNS listing, Caddyfile generation
- Backup & Recovery: create backup, status
- Fleet: list hosts
Protocol: JSON-RPC 2.0 over stdio
Connection: DASHCADDY_URL + DASHCADDY_API_KEY env vars
Any MCP-compatible agent (Claude Desktop, Hermes, GPT) can now:
'I want to stream movies' → wizard recommends Plex/Sonarr/Radarr
'Deploy Plex' → container + Caddyfile + DNS + health check
'Why is Plex down?' → diagnostics with structured findings
'Back up everything' → full snapshot
14 tests, 1752 total pass.
