 -   **Security Hardening:** Implemented a 5-level recursion depth limit and a field allowlist (`searchable_fields`) for the Search API.
 -   **Non-blocking Concurrency:** Standardized on `asyncio.sleep()` for delay simulation to prevent Gunicorn worker hangs.

 ### V3 CRUD Infrastructure & Security
 - **Modular Object Definitions**: Successfully refactored the monolithic `ae_obj_types_def.py` into a domain-driven structure under `app/object_definitions/`. This improved maintainability while keeping legacy V2 keys for backward compatibility.
 - **Advanced Search (POST)**: Implemented a robust `/search` endpoint supporting recursive AND/OR logic and standardized full-text search via the `q` property.
+- **Soft Delete Implementation**: Updated `DELETE /v3/crud/{obj}/{id}` and its child equivalent to support a `method` query parameter (`delete`, `hide`, `disable`). This allows for soft deletion by setting `hide=True` or `enable=False`, while preserving the default hard delete behavior.
+- **Badge Model Updates**: Added `print_count`, `print_first_datetime`, and `print_last_datetime` to `Event_Badge_Basic_Base` to ensure these fields are returned in basic badge queries.
 - **Security Hardening**: Enforced a 5-level recursion depth limit and a field allowlist (`searchable_fields`) per object to prevent unauthorized data leaks.
 - **JWT Authentication**: Implemented modern JWT validation for V3, supporting both the `Authorization` header and a `jwt` query parameter (enabling secure, header-free file downloads).
 - **Frontend Integration**: Created a dedicated `V3_FRONTEND_API_GUIDE.md` to help the Svelte Gemini agent and developers migrate to the new endpoints.
