+## v0.62d production Docker packaging established
+
+- `Dockerfile` — minimal multi-stage Alpine build (Node 22), Next.js standalone output mode
+- `.dockerignore` — excludes dev artefacts, secrets, docs from build context
+- `next.config.mjs` — added `output: 'standalone'` (required for lean production container)
+- `.env.example` — reorganized: Supabase → Ollama → Mock sections; Ollama vars now tracked as deployment-relevant
+- **npm production build: PASS** ✓
+- **Docker image build: BLOCKED** — no Docker runtime on development machine (apparatus limitation, not product defect)
+- Production container starts / `/api/health` smoke test: pending Docker runtime availability
+- No persistent application volume required
+- Supabase remains external, Ollama remains private and server-reachable
+- Public `NEXT_PUBLIC_*` variables may require build-time injection via `--build-arg` as established by the implementation (baked into browser bundle)
+- **No deployment performed yet**
+
 ## CURRENT MVP DIRECTION
 
 Initial-decomposition hardening is frozen for the current MVP stage.

 # Current Project State — Confidence Engine

+- `Dockerfile` created: multi-stage Alpine build (Node 22), Next.js standalone output, configurable port 3000, health-check boundary via `/api/health`
+- `.dockerignore` created: excludes `node_modules`, `.next`, secrets (`env.*.local`), docs, IDE, OS artefacts
+- `next.config.mjs`: added `output: 'standalone'` for lean production container (only config change required)
+- `.env.example`: reorganized; Ollama variables now tracked as deployment-relevant env vars
+- npm production build: PASS ✓
