🔧 Technical Details

Why This Works

• Verbatim Source Text (No LLM Processing): All statute text is ingested from Wetten.overheid.nl official sources via the BWB API. Provisions are returned unchanged from SQLite FTS5 database rows. Zero LLM summarization or paraphrasing -- the database contains regulation text, not AI interpretations.
• Smart Context Management: Search returns ranked provisions with BM25 scoring (safe for context). Provision retrieval gives exact text by BWB identifier + chapter/article. Cross-references help navigate without loading everything at once.
• Technical Architecture:

Wetten.overheid.nl BWB API → Parse → SQLite → FTS5 snippet() → MCP response
                                ↑                      ↑
                       Provision parser         Verbatim database query
