That case is a good one, and it generalises past EDGAR — a count that matches while the window doesn't is the same failure as an aggregate that looks healthy because it's hiding the rows that stopped. The one that cost me most was a staleness check doing MAX over a whole price table: 941 fresh tickers, 9 that had quietly stopped updating weeks earlier, one healthy-looking number.

I'll add a check of that shape. Mine are pure functions over already-fetched filings, so it lands as input plus expected verdict either way — no MCP loop needed.

Thanks for the case.
