 - For plugin-owned fallback runs, operators must opt in with `plugins.entries.<id>.subagent.allowModelOverride: true`.
 - Use `plugins.entries.<id>.subagent.allowedModels` to restrict trusted plugins to specific canonical `provider/model` targets, or `"*"` to allow any target explicitly.
 - Untrusted plugin subagent runs still work, but override requests are rejected instead of silently falling back.
+- Plugin-created subagent sessions are tagged with the creating plugin id. Fallback `api.runtime.subagent.deleteSession(...)` may delete those owned sessions only; arbitrary session deletion still requires an admin-scoped Gateway request.
 
 For web search, plugins can consume the shared runtime helper instead of
 reaching into the agent tool wiring:
