HPDFSignVerify

Value	Purpose
`vesNone`	No source recorded; the source fields hold this value until real evidence is applied
`vesCMS`	Revocation material such as CRLs found embedded within the CMS SignedData itself
`vesPDFVRI`	Evidence gathered from the PDF VRI dictionary of the signed document
`vesPDFDSS`	Evidence gathered from the PDF document security store (DSS)
`vesCaller`	Evidence handed over through the `THPDFCertificateValidationOptions` arrays; also the fallback for array entries with no explicit source
`vesCache`	Revocation evidence brought back from the shared cache of a batch validation run

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