Use these guides to establish transport boundaries, select the correct protocol edition and verify checksums, signaling and media before interpreting individual fields.
Most field-decoding failures begin earlier than the field itself. This guide validates stream boundaries, unescaped bytes, checksum and header layout before interpreting a message body.
Inter-platform captures fail when transport boundaries, escaping, declared length and peer configuration disagree. This guide establishes a conservative validation sequence.
A black screen can originate in signaling, transport loss, timestamp handling, PS reconstruction or codec data. This guide isolates each layer in order.
A syntactically valid message can still fail at transaction, dialog, profile or media layers. This guide correlates those layers without exposing credentials or real endpoints.
Hex utilities are useful only when the byte boundary and interpretation assumptions are explicit. This guide keeps representation work separate from protocol meaning.
