"""Insider filings and prediction-market odds are bounded by the run's trade date.
|
|
|
|
Neither tool takes a date from the model, so the run's trade_date is injected from
|
|
graph state. Insider filings carry dates and are filtered to it; Polymarket serves
|
|
only live odds, so a historical run withholds them.
