-# Project Context: AI Char Bot
-
-## Overview
-Python backend project using FastAPI and MongoDB (Motor).
-Root: `/Users/xds/develop/py projects/ai-char-bot`
-
-## Architecture
-- **API Layer**: `api/endpoints` (FastAPI routers).
-- **Service Layer**: `api/service` (Business logic).
-- **Data Layer**: `repos` (DAOs and Repositories).
-- **Models**: `models` (Domain models) and `api/models` (Request/Response DTOs).
-- **Adapters**: `adapters` (External services like S3, Google Gemini).
-
-## Coding Standards & Preferences
-- **Type Hinting**: Use `Type | None` instead of `Optional[Type]` (Python 3.10+ style).
-- **Async/Await**: Extensive use of `asyncio` and asynchronous DB drivers.
-- **Error Handling**:
-    - Repositories should return `None` if an entity is not found (e.g., `toggle_like`).
-    - Services/Routers handle `HTTPException`.
-
-## Key Features & Implementation Details
-- **Generations**:
-    - Managed by `GenerationService` and `GenerationRepo`.
-    - `toggle_like` returns `bool | None` (True=Liked, False=Unliked, None=Not Found).
-    - `get_generations` requires `current_user_id` to correctly calculate `is_liked`.
-- **Ideas**:
-    - Managed by `IdeaService` and `IdeaRepo`.
-    - Can have linked generations.
-    - When fetching generations for an idea, ensure `current_user_id` is passed to `GenerationService`.
-
-## Recent Changes
-- Refactored `toggle_like` to handle non-existent generations and return `bool | None`.
-- Updated `IdeaRouter` to pass `current_user_id` when fetching generations to ensure `is_liked` flag is correct.
