+# Feature Epics
+
+## Repository
+kitchen-service
+
+## Core Epics
+- Epic 1: Expand domain-aligned capabilities for restaurant operations.
+- Epic 2: Stabilize service contracts for containerized runtime integration.
+- Epic 3: Improve observability and operational readiness for demo compose environments.
+
+## Domain-Specific Candidate Features
+- Order lifecycle consistency and state transitions.
+- Kitchen queue and dispatch optimization hooks.
+- Operations control-plane policies (flags, service windows, overrides).
+- POS closeout and settlement summary alignment.
+
+## Documentation Contract
+Any code change in this repository must include docs updates in the same branch.

+# Containerization Runbook
+
+## Image Build
+
+If the repo consumes internal packages from Gitea, pass feed credentials as build args.
+
+```bash
+docker build   --build-arg NUGET_FEED_USERNAME=<gitea-login>   --build-arg NUGET_FEED_TOKEN=<gitea-token>   -t agilewebs/kitchen-service:dev .
+```
+
+## Local Run
+
+```bash
+docker run --rm -p 8080:8080 --name kitchen-service agilewebs/kitchen-service:dev
+```
+
+## Health Probe
+
+- Path: `/health`
+- Fallback path: `/healthz`
+- Port: `8080`
+
+## Runtime Notes
+
+- Exposes internal queue and order state transition endpoints.
+
+## Health Endpoint Consistency
+
+- Canonical probe: `/health`
+- Compatibility probe: `/healthz`
+- Container port: `8080`
+
+## Demo Integration
+
+- Participates in: **restaurant** demo compose stack.
+- Integration artifact path: `greenfield/demo/restaurant/docker-compose.yml`
+## Known Limitations
+
+- Current runtime adapters are still predominantly in-memory for deterministic local/demo behavior.
+- Demo PostgreSQL seeds validate integration contracts and smoke determinism, but do not yet imply full persistence implementation parity.
