 This is not a toy converter. It handles real-world PineScript with 240+ function mappings, full series semantics, state persistence across bars, multi-timeframe support, and a post-conversion reviewer that catches problems before they hit you at runtime.

 - Runs a multi-stage post-conversion reviewer that catches syntax errors, missing functions, and conversion artifacts

-### Optional AI review
-
-The repo includes a fully local AI reviewer that runs a small code model on your machine. No server, no API key, no data leaves your laptop.
-
-Default model: `Qwen/Qwen2.5-Coder-0.5B-Instruct` (fast, low RAM)
-Larger model: `Qwen/Qwen2.5-Coder-1.5B-Instruct` (better results, slower)
-
-Setup:
-
-```bash
-pip install -r ai_reviewer/requirements.txt
-```
-
-Run with AI review enabled:
-
-```bash
-PINE_REVIEW_AI=1 node src/cli.js script.pine output.js --review-ai
-```
-
-Note: Small models can produce repetitive or low-quality output. The reviewer sanitizes bad responses and will suggest switching models if needed.
