 # Aether Project Brief: aether_api_fastapi
-**Last Updated:** 2026-01-28 19:21:44
+**Last Updated:** 2026-02-05 20:19:52
 **Current Agent:** mcp_agent
 
 ## 🛠️ What I Just Did
-Implemented GET /v3/data_store/code/{code} with cascading lookup and limit override. Refactored Data_Store_Base for ID Vision standard. Created ARCH__V4_CORE_STANDARDS documentation. Updated and synced GUIDE__V3_FRONTEND_API. Fixed legacy data_store router crashes. Unified E2E testing for Data Store.
+- Standardized Event and CMS (Post/Comment) models to 'ID Vision' (clean string IDs).
+- Hardened model root_validators to support standardized creation/search workflows.
+- Implemented 'physical', 'virtual', and 'external_person_id' in Event schema.
+- Updated Post Comment views to join account context relationaly.
+- Created 'tests/e2e/test_e2e_v3_cms_vision_parity.py' for long-term verification.
+- Synced updated V3 Frontend Guide to 'agents_sync' mesh.
 
 ## 🚧 Current Blockers
-None. System is stable at release baseline v3.0.99.
+None. (Lesson learned on DDL overreach).
 
 ## ➡️ Exact Next Steps
-1. Begin Aether API V4 lifecycle field migration (approved_on, enable_on, archive_on). 2. Standardize Search Optimization (default_qry_str) across all core objects. 3. Unify Websocket infrastructure.
+- Audit 'hosted_file' and 'event_file' usage for regressions after recent refactors.
+- Continue refactoring monolithic files (>800 lines): 'api_crud_v2.py' and 'person_methods.py'.
+- Monitor frontend feedback on the standardized ID Vision documentation.

 - **Vision ID Persistence**: Pydantic `Field(exclude=True)` strips fields from `.dict()` by default. In methods like `create_hosted_file_obj`, these must be explicitly re-included if they are internal DB fields (like `subdirectory_path`).
 - **Universal ID Resolution**: `GET /v3/action/hosted_file/{id}/download` now intelligently resolves container IDs (`event_file`, `archive_content`) to physical binaries.
 - **Temporary Access Patterns**: Implemented `?key=` and `?site_key=` (using `access_key`) for unauthenticated Read-Only file access to unblock frontend components like `<img>`.
+- **ID Vision Standardization**: Standardized Event and CMS models to clean string IDs. Learned that `root_validator(pre=True)` must be hardened during the "Create" phase to prevent deleting integer IDs resolved by `sanitize_payload`.
+- **Relational View Joins**: Established that account context for child objects (like `post_comment`) should be inherited via SQL `INNER JOIN` in the view (`v_post_comment`) rather than duplicating columns in the physical table.

 - **[Zoom Events]:** initial integration complete (OAuth2, Sync logic, Ticket retrieval). Pending real credentials.
 - **[Refactor]:** Reduced monolithic files (>800 lines). `api_crud.py` and `hosted_file.py` COMPLETED. `api_crud_v2.py` and `person_methods.py` PENDING.
-- **[Test Suite]:** E2E suite consolidated into primary functional suites (Search, Auth, Lifecycle, Vision).

-- **Status:** Operational / Refactored
-- **Last Action:** Finalized monolithic refactor and initial Zoom Events integration.
+- **Status:** Operational / Standardized
+- **Last Action:** Finalized ID Vision standardization for Event and CMS modules.
 - **Achievements:** 
-    - Reduced `api_crud.py` (1843 -> 143 lines).
-    - Reduced `hosted_file.py` (1596 -> 361 lines).
-    - Implemented Zoom Events OAuth2 and Sync backend.
-    - Verified Full File Lifecycle (Upload -> Download -> Delete) via standardized E2E test.
-- **Immediate Next Step:** Await further instructions.
+    - Standardized Event models (Event_Base, Flat) to string IDs.
+    - Fixed Post Comment validation bug (integer purge during POST).
+    - Verified account context inheritance via view joins.
+    - Created `test_e2e_v3_cms_vision_parity.py`.
+    - Updated V3 Frontend Guide and notified Frontend agent.
+- **Immediate Next Step:** Audit `hosted_file` and `event_file` usage for regressions.
