 ## Runtime Notes
 
 - Exposes REST edge endpoints for waiter assignment and order submission flows.
+- Requires `ThalosAuth__BaseAddress` to resolve Thalos session introspection endpoint.
+- Returns standardized auth failures (`401|403|503`) with `x-correlation-id` propagation.
 
 ## Health Endpoint Consistency
 

docs/security/auth-enforcement.md

@@ -38,8 +38,13 @@ Standard auth error payload:
 
 - `401`: missing or invalid session
 - `403`: permission denied by identity service
+- `503`: identity service unavailable or timeout (`identity_unavailable|identity_timeout`)
 
 ## Correlation
 
 - Incoming/outgoing correlation header: `x-correlation-id`
 - Correlation ID is forwarded to Thalos session validation call.
+
+## Validation Rule
+
+- Successful session introspection must also include `isAuthenticated=true` in Thalos response payload.
