+# Waiter Floor Workflow API
+
+## Purpose
+
+This BFF exposes execution-facing waiter workflows over REST while delegating orchestration to `operations-service`.
+
+## Endpoints
+
+- `GET /api/waiter/floor/assignments?contextId=<value>`
+  - Returns assignment summary, location context, current assignments, and recent activity.
+- `GET /api/waiter/floor/activity?contextId=<value>`
+  - Returns recent waiter activity projected from the same operations workflow snapshot.
+- `POST /api/waiter/floor/orders`
+  - Submits a waiter order snapshot for processing.
+- `PUT /api/waiter/floor/orders/{orderId}`
+  - Updates an existing waiter order snapshot using the same operations workflow contract.
+
+## Upstream Dependency
+
+- Base address configuration: `OperationsService:BaseAddress`
+- Default runtime target: `http://operations-service:8080`
+- Internal upstream routes:
+  - `GET /internal/operations/waiter/assignments`
+  - `POST /internal/operations/orders`
+
+## Notes
+
+- The update route currently reuses the operations order submission contract so waiter-floor can expose update semantics without introducing a new cross-repo dependency.
+- Correlation IDs are preserved through Thalos session checks and operations-service calls.

+- Owns edge contracts for assignment views, recent floor activity, and order submit or update orchestration.

 ## Domain-Specific Candidate Features
 - Order lifecycle consistency and state transitions.
+- Waiter assignment visibility with recent floor activity context.
+- Waiter order update workflows that stay aligned with service-level restaurant order orchestration.
 - Kitchen queue and dispatch optimization hooks.
 - Operations control-plane policies (flags, service windows, overrides).
 - POS closeout and settlement summary alignment.

 - Integration artifact path: `greenfield/demo/restaurant/docker-compose.yml`
 ## Known Limitations
 
-- Current runtime adapters are still predominantly in-memory for deterministic local/demo behavior.
+- Waiter-floor now delegates workflow snapshots to `operations-service`, but the upstream operations adapter still serves deterministic demo data rather than database-backed state.
 - Demo PostgreSQL seeds validate integration contracts and smoke determinism, but do not yet imply full persistence implementation parity.
