 ## Current To-Do List
 
 1. **Docker Environment Insight Improvements (Priority: High)**: Implement methods/endpoints to give the agent more insight into the actual Docker runtime environment.
-2. **Security - Field Allowlists (Priority: High)**: Finish populating `searchable_fields` for all remaining object definitions.
+2. **Security - Field Allowlists (Priority: Done)**: Finished populating `searchable_fields` for all object definitions (Core, CMS, Events, Membership, Orders, Other).
 3. **Refactoring - Modularize `db_sql.py` (Priority: Done/Low)**: Successfully implemented a facade pattern, moving search builders and Redis helpers to modular files. This reduced `db_sql.py` by nearly 500 lines while preserving stability. Further modularization of core CRUD should only be attempted if stability risks are mitigated.
 4. **Specialized Endpoints (Priority: Medium)**: Plan modernization of custom logic (importing, websockets) to match V3 patterns.
 5. **Security - Authentication (Priority: High)**: Continue refining and enforcing JWT-based authentication across all V3 endpoints.
 
+### Workflow & Collaboration
+- **`GEMINI.md` Strategy:** The user is creating `GEMINI.md` files in key project directories. Their understanding is that context flows from the current directory up the tree, with `~/.gemini/GEMINI.md` serving as a global catch-all for general memories.
+- **Agents Sync (rsync):** Shared documentation, notes, and architectural updates are pushed to the `agents_sync` directory using `rsync`. This allows real-time coordination between different specialized agents (e.g., FastAPI backend and Svelte frontend agents).
+- **Home Server:** The user self-hosts a Proxmox server for services like Nextcloud.
