Module rag 

RAG pipeline for hardware datasheet retrieval.

Supports:

• Markdown and text datasheets (always)
• PDF ingestion (with rag-pdf feature)
• Pin/alias tables (e.g. red_led: 13) for explicit lookup
• Keyword retrieval (default) or semantic search via embeddings (optional)

Structs

DatasheetChunk

A chunk of datasheet content with board metadata.

HardwareRag

Hardware RAG index — loads and retrieves datasheet chunks.

Type Aliases

PinAliases

Pin alias: human-readable name → pin number (e.g. “red_led” → 13).
