 # Settings Integration Configuration Model
 
-This document records the logical model behind the Settings -> Integrations page.
+This document records the current logical model behind Settings -> Integrations,
+with the provider catalog aligned to the bridge-only design.
 
-The page is organized into three layers:
+## Current Rule
 
-- User login state
-- Base connection configuration
-- Advanced custom mode
+- Settings only manages bridge connection parameters and upstream sync
+  definitions.
+- The provider picker is not derived from local endpoint presets.
+- `xworkmate-bridge` is the only source of truth for the provider catalog.
 
-The base connection layer is the default configuration surface. It represents the connection identity that can come from either `svc.plus` or a self-hosted service. Advanced custom mode does not replace the base layer; it overrides selected defaults on top of it.

 ## Notes
 
-- User login state describes authentication only.
-- Base connection configuration describes the default connection path and identity.
-- Advanced custom mode is a layered override mechanism.
-- The effective runtime configuration is computed from the base layer plus any advanced overrides.
-
+- `externalAcpEndpoints` still matters, but only as bridge sync input.
+- Provider visibility, picker contents, and auto-provider resolution all come
+  from `acp.capabilities.providers`.
+- `openclaw` and other mount-target discovery states are also bridge-owned and
+  come from ACP capabilities merged into `ManagedMountTargetState`.
+- Persisted thread `providerId` restores the user's previous selection, but it
+  does not repopulate the provider catalog.
