+# Furniture DAL Domain Alignment
+
+## Goal
+Align DAL with furniture-domain abstractions while keeping DAL technical.
+
+## DAL Responsibilities
+- Persistence and retrieval
+- Technical data translation
+- Provider/repository boundaries
+- Contract adaptation for service and domain boundaries without owning decisions
+
+## Prohibited
+- Domain decision ownership
+- Service orchestration concerns

+# Furniture DAL Package Consumption Baseline
+
+## Objective
+
+Remove cross-repo source coupling from `Furniture.DAL` and consume shared contracts through NuGet packages.
+
+## Applied Baseline
+
+`Furniture.DAL.csproj` now consumes:
+
+- `BuildingBlock.Catalog.Contracts` `0.2.0`
+- `Core.Blueprint.Common` `0.2.0`
+
+## Feed Configuration
+
+Repository-level `nuget.config` includes:
+
+- `gitea-org`: `https://gitea.dream-views.com/api/packages/AgileWebs/nuget/index.json`
+- `nuget.org`
+
+Because feed is currently HTTP, `allowInsecureConnections="true"` is required for the Gitea source.
+
+## Boundary Notes
+
+- No cross-repo `ProjectReference` remains in `src/Furniture.DAL/Furniture.DAL.csproj`.
+- DAL remains technical/provider-oriented and independent from BFF/Service source coupling.

+# DAL Port Alignment Map

+## Alignment Areas
+- DAL read/write ports map to domain contracts.
+- Technical DTO translation remains in DAL adapters.
+- Domain invariants are not reimplemented in DAL.

+## Rules
+- Mapping logic must remain technical and deterministic.

+# Feature Epics
+
+## Repository
+furniture-dal
+
+## 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.

+## Image Build

+```bash
+docker build   --build-arg NUGET_FEED_USERNAME=<gitea-login>   --build-arg NUGET_FEED_TOKEN=<gitea-token>   -t agilewebs/furniture-dal:dev .
+```
+
+## Local Run
+
+```bash
+docker run --rm -p 8080:8080 --name furniture-dal agilewebs/furniture-dal:dev
+```
+
+## Health Probe
+
+- Path: `/health`
+- Fallback path: `/healthz`
+- Port: `8080`
+
+## Runtime Notes
+
+- Exposes internal DAL lookup endpoints for furniture availability and catalog projections.
+- In-memory demo provider accepts canonical demo IDs (`FURN-001..003`) and aliases (`demo-context`, `FUR-*`, `PRD-*`, `PROD-FURN-*`).
+
+## Health Endpoint Consistency
+
+- Canonical probe: `/health`
+- Compatibility probe: `/healthz`
+- Container port: `8080`
+
+## Demo Integration
+
+- Participates in: **furniture** demo compose stack.
+- Integration artifact path: `greenfield/demo/furniture/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.
