+# Booking Domain Boundary
+
+## Purpose
+
+Booking procedures for rooms, resources, counters, equipment, appointment types, public slots, internal reservations, waiting lists, cancellations, attendance, and no-shows.
+
+## Owns
+
+- booking procedures
+- public and internal slot allocation
+- waiting lists
+- reservation lifecycle
+- attendance and no-show facts
+
+## Does Not Own
+
+- resource inventory master data
+- calendar event storage
+- generic approval engine
+
+## Integration Candidates
+
+- resources
+- calendar
+- appointments
+- scheduling
+- mail
+- notifications
+- files
+- workflow
+- approvals
+- portal
+
+## Seed State
+
+The current repository state is intentionally small:
+
+- module manifest and entry point
+- tenant-level permission definitions
+- manager and viewer role templates
+- documentation topic describing the module boundary
+- Gitea issue workflow templates
+- manifest contract test
+
+No runtime API, database model, migration, WebUI route, or navigation item is registered yet. The first implementation slice should preserve the boundary above and only add user-visible surfaces once the workflow model is clear.
+
+## First Implementation Slice
+
+Define booking type, slot, reservation, attendance, cancellation, and no-show concepts, then add APIs for tenant-local booking configuration.
