EXPLICIT BOUNDARIES

Two layers, never conflated

Official C2PA layer
c2pa-python reads manifests and validates media bindings.
H/M interoperability layer
Verifies H/M JSON, audit and BagIt contracts locally.
Identity boundary
A checksum is not a signature and does not authenticate an exporter.
Truth boundary
Neither layer proves factual truth, authorship, AI absence or legal compliance.
