Could you build this?

Partial Aggregating public 13F and Form 4 filings from SEC EDGAR is buildable, but the proprietary Pulse Scores and signal-confidence logic require a novel, validated analytical model that vibe coding won't produce.

What it would actually take: Ingest EDGAR bulk data for 13F and Form 4 filings, normalize holdings and insider transactions, and display them in a dashboard. The hard part is designing and backtesting a scoring model that actually predicts something, which requires quantitative finance expertise and historical data pipelines.
