Vidéo et 3D : prise en charge réduite dans la version actuelle.
public layer
Invisible, non modifiable.
Markers live in the contenu's semantic structure, so they are not removable like a visible overlay nor forgeable like a metadata tag. Verification is deterministic and reproducible across hosts; the chaîne de provenance is cryptographic rather than trust-based.
stated openly
Là où le système est plus faible.
Video and 3D have reduced support today; severe transformations (major edits, re-encoding) can break verification — use the original for the strongest check. Independent cryptographic audit is scheduled and available to évaluation partners under NDA. Marker-generation mechanics and the frozen cœur stay sealed.
