 - [x] **CodeMirror Migration:** Replaced all instances of the old Tiptap editor with a new CodeMirror wrapper. This includes fixing initialization errors, enabling text wrapping, and ensuring content is correctly saved.
 - [ ] **Component Review:** Audit third-party components to understand their conventions and isolate them from internal standards.
 
+### 3. Aether Object Field Definitions
+
+- [ ] **Goal:** Create a common way to define which fields can be sent in when creating or updating a record for all Aether objects.
+- [ ] **Process:**
+    - For each Aether object type, create a `ae_<module>__<object>.editable_fields.ts` file that exports a whitelist of editable fields.
+    - Modify the `create` and `update` functions for each object type to use this whitelist to filter the data before sending it to the API.
+    - Start with the `event` object type as a proof of concept. (DONE)
+    - Apply this pattern to all other Aether object types.
