+# 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.
