Every card below shows the score and the exact filing data it was computed from โ€” no unexplained numbers. Some signals (P-02, P-03, P-08, P-09, P-10, P-11) pull live documents from SEC EDGAR the first time you view this company; a few of those (P-03, P-10, P-11) use AI to read the filing text, but every AI claim must quote the actual document verbatim or it's discarded โ€” never a guess.
