 ## Contract
 
-- Tools may return a subscribable resource hint after a successful provider
+- Tools may return a subscribable resource hint after a successful plugin
   operation.
 - Core owns subscription creation, cancellation, expiry, deduplication, and the
   conversation association.
 - Inspection and stop actions stay in the tool catalog. A successful
-  subscription result identifies the exact no-argument catalog call that stops
-  every resource watch for the conversation.
+  subscription result identifies the exact watch id to stop. Omitting that id
+  is reserved for an explicit request to stop every watch in the thread.
 - A thread opt-out cancels every active subscription for that conversation
   before the Slack thread is marked unsubscribed.
-- Provider route code validates and normalizes incoming events before calling
+- Plugin route code validates and normalizes incoming events before calling
   the ingestion boundary.

-- Normalized events contain stable provider/resource identity and a bounded,
+- Plugin-owned routes publish normalized events through the route-hook resource
+  event publisher; core binds the plugin namespace and never needs the raw
+  provider webhook. Publication requires an active registration that declares
+  the event type.
+- Plugins declare resource types, supported and suggested event types, and
+  ingress readiness on their registration. Core builds one enabled runtime
+  catalog for search, tool schemas, and validation.
+- `searchResourceEventTypes` discovers that catalog without creating anything.
+  `watchResourceEvents` creates a temporary resource subscription for the
+  current Slack thread. Concrete identifiers still come from plugin tool
+  results rather than catalog enumeration.
+- Core validates namespace, resource type, and event ownership again before
+  storing a subscription.
+- Normalized events contain a stable namespace and identifier plus a bounded,
   safe notification summary rather than a raw webhook payload.
 - Ingestion appends a system-authored conversation message and sends a normal
   task-execution wake-up.
+- A subscription selector is one namespace, one identifier, and one or more
+  event types. `resourceType` and `label` are presentation metadata, not match
+  keys.
 - Duplicate provider deliveries must not create duplicate conversation work.
 - A plugin cannot use a resource event to widen conversation visibility or
   credential authority.
+- Watches default to 14 days and reject requested lifetimes over 30 days rather
+  than silently shortening them.
