     - Created `editable_fields` definitions for Archives and Archive Content.
 - **Core Placeholders:** Built logic and UI placeholders for **Addresses** and **Contacts** at `/core/addresses` and `/core/contacts`.
 - **Navigation Update:** Integrated the new Address and Contact management routes into the core layout navigation.
+- **Inter-Agent Communication:** Established identity as `frontend_svelte` and confirmed the file-based "Inbox" messaging system via `agents_sync/inbox` for coordination with `backend_fastapi` and other agents.
 
 **Key Learnings:**
 - **API Health Monitoring:** Learned to use `curl -s https://dev-api.oneskyit.com/v3/crud/health` for direct backend health checks, bypassing frontend complexity during diagnosis.
 - **Client Error Handling:** It is critical to differentiate between network failures (worth retrying) and client errors (400, 403) which indicate fundamental request issues.
 - **Nested CRUD Pattern:** Successfully applied the `create_nested_obj_v3` and `delete_nested_ae_obj_v3` patterns to the Event Badge and Archive Content modules.
+- **Agent Coordination:** The `agents_sync/inbox` provides a low-friction way to align frontend and backend efforts, especially during breaking API transitions.
 
 **Next Steps:**
 - **Bulletin Board (Posts):** Migrate `ae_posts` to V3 CRUD.
 - **Person Activity UI:** Finalize the "Linked Activity & Content" section in the Person detail view to show real related data.
 - **Address/Contact Details:** Build out the detail pages for these new modules.
+- **Agent Inbox:** Periodically check `/home/scott/agents_sync/inbox/frontend_svelte/` for messages from the backend agent.
