Two new nightly enrichments for the day's tracked names, both SHADOW
ONLY (float was refuted as a gate; a filings-based dilution veto needs
its own pre-registered bar):
- research/ingestion/float_cache.py: FMP stable shares-float ->
float_cache table (free-plan budget guards: 7-day refresh, 200
calls/run). First real float data in the system — LHSW's +346% ran
on a 1.1M float; BJDX is 0.4M.
- research/ingestion/sec_dilution.py: SEC EDGAR full-text search (free,
keyless, fair-use paced) -> populates the previously-empty
dilution_events table with S-1/S-3/424B filings; TVRD + BJDX flag
immediately. recent_dilution() helper for future veto work.
Wired into premarket_eval nightly. Not wired: Polygon/AlphaVantage/
TwelveData/Marketstack/EODHD (redundant vs paid Alpaca SIP) and the
generic news aggregators (slower than Alpaca/Benzinga, dedup noise).
