### Purpose
Perform deterministic workout analysis and generate reports/charts

### Core Requirements
- **Analysis Capabilities**
  - FIT/TCX/GPX file parsing
  - Power, heart rate, and speed analysis
  - Training metrics calculation (TSS, IF, NP)
  - Zone distribution analysis
  - Chart generation (power curves, elevation profiles)

- **API Endpoints**
  - `POST /api/analyze/workout` - Analyze single workout
  - `POST /api/analyze/batch` - Analyze multiple workouts
  - `GET /api/analysis/{id}/charts` - Generate charts
  - `GET /api/analysis/{id}/summary` - LLM-ready summary

- **Technical**
  - CPU-intensive processing isolation
  - Support for existing GarminAnalyser codebase
  - Chart generation (PNG, HTML, PDF)
  - Standardized output format for LLM consumption
  - Result caching


  - **Existing Code**
  - Use @GarminAnalyser.md to pull code from the existing implementation
  - use @DB_API_SPEC.json to get the API spec for the CentralDB that will store the Activity files and artifacts that we create
