HPDFSignVerify

Value	Purpose
`vesNone`	No source recorded; source fields keep this value until real evidence is applied
`vesCMS`	Revocation material such as CRLs found embedded in the CMS SignedData itself
`vesPDFVRI`	Evidence harvested from the PDF VRI dictionary of the signed document
`vesPDFDSS`	Evidence harvested from the PDF document security store (DSS)
`vesCaller`	Evidence handed in through the `THPDFCertificateValidationOptions` arrays; also the fallback for array entries without an explicit source
`vesCache`	Revocation evidence restored from the shared cache of a batch validation run

Source arrays such as OCSPResponseSources, CRLSources, and DeltaCRLSources are parallel to the evidence arrays; a non-vesNone entry overrides the vesCaller fallback
The source of the winning revocation evidence is reported in THPDFCertificateValidationInfo.RevocationSource and DeltaCRLSource
Comparing sources tells apart evidence embedded by the signer from material collected later during LTA-style evidence acquisition
