Filing reader

In-line read of any filing's primary document, with auto-extracted sections and key risk-factor highlighting.

Pending wiring

Reader fetches the primary HTML document from SEC, sanitizes, and extracts structure:

Fetch /Archives/edgar/data/{cik}/{acc}/{primaryDoc} and run through DOMPurify
Section extraction: Items (1A risk factors / 7 MD&A / 7A market risk / 9A controls)
Risk-factor highlighting (LM-dictionary based) overlays a heat strip in the right margin
Anchor index in the left rail; deep-link `?section=item-1a`
One-click “Summarize this filing” → /ask with the document body as context
