THPDFHeadlessSignatureReservation

A borrowed offset record created by HPDFWriteHeadlessSignatureReservation in HPDFHeadlessSignatureWriter

FieldMeaning
ObjectOffset, ObjectLengthAbsolute signature object position and serialized object extent
ByteRangeOffsets[0..3]Absolute positions of the four fresh 20-digit numeric patch slots
ContentsStart, ContentsEndAbsolute gap bounds, including the opening and closing hexadecimal delimiters
ReservedCMSBytesMaximum DER bytes that fit the reserved hexadecimal Contents value
CAdESThe selected detached signature profile, which must match finalization options
DocumentTimestampTrue selects a genuine RFC3161 document timestamp reservation and its timestamp-specific finalizer

The stream must remain seekable and read/write until finalization; do not change this record, reuse it with another output, or finalize it twice

Finalization validates object bounds, gap size, numeric-slot ordering, fresh numeric zeros, and gap delimiters before patching
