Returns one entry per signature: the signer, the issuing CA, the claimed signing time, the eIDAS qualification (QESig / AdESig / Unknown), and the individual checks \u2014 byte-range integrity, CMS/PKCS#7 cryptographic validity, EU trusted-list anchoring, and whether the signature covers the whole document. Partial coverage is reported as a fact, not as tampering. Consumes 1 verification credit."
