# DisCoPy Execution Sub-module

## Overview

Execution module for DisCoPy categorical diagrams generated by Step 11 (Render). Validates and analyzes DisCoPy diagram structures, verifying compositional correctness and computing categorical properties.

## Architecture

```

discopy/

├── __init__.py # Package exports and entry point

└── discopy_executor.py # DisCoPy validation and analysis engine (436 lines)

```

## Key Functions

- **`execute_discopy(script_path, output_dir)`** — Validates and executes a rendered DisCoPy diagram script.

- **Diagram validation** — Verifies categorical composition rules (functoriality, naturality).

- **Property computation** — Computes diagram invariants and structural properties.

- **Result serialization** — Outputs execution results as JSON for downstream analysis.

## Dependencies

- `discopy` (optional, graceful degradation if missing)
