 ## Session Learnings & Progress (Jan 2-7, 2026)
 
-### Agent Bridge & Docker Integration (Jan 7, 2026)
-- **Agent Bridge Implementation**: Developed `app/routers/agent_bridge.py` to provide administrative insight into the Docker runtime environment.
-    - Endpoints include `/status`, `/system/usage`, `/logs`, `/logs/list`, `/processes`, and `/container/metadata`.
-    - Implemented `is_admin` helper for consistent security across administrative tools.
-    - Added support for listing and tailing various log files, with path sanitization.
-- **MCP Docker Explorer**: Created `mcp_docker_explorer.py` as a standalone client to test the Model Context Protocol (MCP) Docker server integration. This script uses `npx` to run `@modelcontextprotocol/server-docker`.
-- **Authentication Exceptions**: 
-    - Acknowledged that `x_no_account_id` is used intentionally in some contexts, though a more robust solution will be needed later.
-    - **Direct Download Links**: Noted that Hosted Files and Event Files often require direct download links that cannot include custom headers, as they are often shared directly with users.
+### V3 API Security Hardening (Jan 7, 2026) - MILESTONE
+- **Mandatory JWT Authentication**: Successfully implemented strict multi-tenant isolation across all V3 CRUD and Search endpoints.
+    - All requests (except context resolution) now require a valid JWT `Authorization: Bearer <token>` or `?jwt=<token>`.
+    - **Account Isolation**: results are automatically filtered by `account_id` from the JWT.
+    - **Documentation**: Updated `V3_FRONTEND_API_GUIDE.md` with explicit instructions and security requirements for the frontend agent.
+
+### Agent Bridge & Docker Integration
+- **Agent Bridge Implementation**: Developed `app/routers/agent_bridge.py` for environment diagnostics.
+- **Dependency Management**: Noted `psutil` is missing from the container, causing system usage metrics to fail.
+    - **Decision**: Holding off on adding `psutil` to minimize extra dependencies; the code fails gracefully for now.
+- **MCP Docker Explorer**: Created `mcp_docker_explorer.py` to test MCP server integration.
 
 ### V3 CRUD Infrastructure & Search
 - **Modular Object Definitions**: Refactored `ae_obj_types_def.py` into modular domain files in `app/object_definitions/`.
 - **Advanced Search Fixes**: 
-    - Resolved account listing and search issues by implementing `get_supported_filters` in `api_crud_v3.py`. This helper automatically adjusts `status_filter` (enabled/hidden) based on model field support (e.g., handles tables missing the `hide` column).
-    - Improved standardized full-text search (`q` parameter) in `sql_search_qry_part` with a dry-run check for the `default_qry_str` column. It now falls back to a `LIKE` search across all searchable fields if the column is missing.
-    - Added support for the `%` wildcard in `q`, allowing it to bypass filtering and return all records.
-- **Data Integrity & Aliasing**: Fixed a critical issue where aliased fields (like `account_id_random`) were returned as `null` by adding `allow_population_by_field_name = True` to Pydantic models (updated `Account_Base`, `Site_Domain_Base`, etc.).
-- **Consolidated V3 Router**: Systematically cleaned up `api_crud_v3.py`, removing duplicate endpoint definitions and standardizing logic across all CRUD and Search routes.
-- **Robust Error Handling**: Updated V3 routers to return 500 status codes on database failures instead of masking errors with empty result sets.
+    - Resolved account listing and search issues by implementing `get_supported_filters` in `api_crud_v3.py`.
+    - Improved standardized full-text search (`q` parameter) with fallback logic for missing columns.
+- **Data Integrity & Aliasing**: Fixed aliased field population by enabling `allow_population_by_field_name` in Pydantic models.
 
-### Database Schema Insights
-- Verified schema for core tables (`account`, `event`, `person`, `user`, `data_store`, `site`, `site_domain`).
-- Noted that `site_domain` lacks a `hide` column, and `hosted_file_link` lacks both `hide` and `enable`.
-- Most major tables now have a standardized `hide` column (added to `account` on Jan 6, 2026).
+### Tool Stability & Recovery Note (Jan 7, 2026)
+- **Frequent Hangs:** The agent experienced multiple hangs (18+) when using shell commands or `list_directory`.
+- **Recovery Action:** A `NameError: name 'SearchFilter' is not defined` in `app/routers/api_crud_v3.py` was fixed by adding the missing import. This error was triggered by the new account isolation logic in the search endpoint.
+- **Verification:** The fix was applied, but verification was interrupted by a tool hang. Verification resumes in the next session.
 
 ## Current To-Do List
 
-1. **Docker MCP Integration (Priority: High)**: Proceed with integrating the Docker MCP server into the Gemini CLI environment for direct container management.
-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.
+1. **Frontend Integration (Priority: High)**: Coordinate with the frontend agent to ensure they adopt the mandatory JWT authentication pattern.
+2. **Routing - Nginx (Priority: High)**: Resolve 404 errors on `/v3/` and `/agent/` routes (Port 8888) by updating the Nginx configuration.
+3. **Docker MCP Integration (Priority: Medium)**: Proceed with integrating the Docker MCP server into the Gemini CLI environment.
 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, while respecting the need for header-less direct download links for certain file types.
-6. **Account ID Handling (Priority: Low)**: Address the `x_no_account_id` usage with a more permanent and secure architecture.
+5. **Account ID Handling (Priority: Low)**: Address the `x_no_account_id` usage with a more permanent architecture.
 
 ### 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.

-## 6. Authentication in V3
+## 6. Authentication and Security in V3 (Mandatory)
 
-V3 supports multiple authentication methods. The backend resolves these automatically.
+Implemented in January 2026, the V3 architecture enforces strict **Multi-Tenant Isolation** and requires valid authentication for nearly all requests.
 
-### A. Standard Requests (Header)
-For most API calls, use the standard Bearer token in the `Authorization` header.
+### A. Authentication Requirement
+Most API calls now require a standard Bearer token in the `Authorization` header.
 
-```ts
-// Example: Setting the JWT in headers
-headers: {
-    "Authorization": `Bearer ${user_jwt_token}`
-}
+*   **Mandatory:** V3 CRUD endpoints require a valid JWT or an administrative bypass header.
+*   **Account Isolation:** The backend automatically filters all results based on the `account_id` found in your JWT. You cannot access data belonging to another account even if you know the ID.
+*   **Status Codes:**
+    *   `401 Unauthorized`: Your JWT is invalid or expired.
+    *   `403 Forbidden`: No authentication provided, or you attempted to access an object belonging to a different account.
+
+**Example Request Header:**
+```http
+Authorization: Bearer <your_jwt_token>
 ```
 
-### B. Secure File Downloads (URL Parameter)
-**Crucial for `hosted_file` and `event_file`**: To allow browsers to download files without complex header modifications, you can pass the JWT directly in the URL.
+### B. Role-Based Access
+The API performs background checks on the user's role stored in the system:
+*   **Managers/Admins:** Can see and edit most data within their account.
+*   **Super Users:** Can bypass account isolation (reserved for system maintenance).
+
+### C. Secure File Downloads (URL Parameter)
+For `hosted_file` and `event_file`, browsers often need to download files without complex header modifications. In these cases, you can pass the JWT directly in the URL.
 
 ```ts
-// Example: Creating a secure download link
+// Example: Creating a secure download link for a browser
 // GET /v3/crud/hosted_file/{id}/?jwt={token}
-const downloadUrl = `${BASE_URL}/hosted_file/${fileId}/?jwt=${jwtToken}`;
+const downloadUrl = `${BASE_URL}/v3/crud/hosted_file/${fileId}/?jwt=${jwtToken}`;
 ```
 
-### C. Legacy Fallback (X-Account-ID)
-For development and backward compatibility, the `X-Account-ID` header is still supported but should be phased out in favor of JWT.
+### D. Administrative Bypass (Utility/Dev only)
+For development utilities and automated scripts, the `X-No-Account-ID: true` header grants full administrative access. **Never use this in a public-facing application.**

-## 5. Best Practices for V3
+## 7. Best Practices for V3
 
 1.  **Use `view` for Rich Data**: Instead of manually joining data in separate calls, use `?view=enriched` or `?view=detail` if defined in the backend.
 2.  **Hybrid Search**: Use query parameters for simple toggles (enabled/hidden) and the POST body for complex logic.
