Protocol: CT.gov Black-Box Sponsor Repeaters

This protocol re-reads the wave-nine sponsor watchlist by centering the black-box subset rather than adjusted missing-results stock alone. Primary outputs compare named-sponsor black-box stock, black-box rate, raw no-results stock, and ghost counts. The aim is to isolate which named sponsors sit inside the deepest registry-visible silence state. Black-box status is defined from registry page fields and does not imply a sponsor had no internal records or dissemination outside CT.gov.
