Tamper-Evident Multi-Layer Labels

The extra plies here are doing security work rather than carrying copy. Depending on the threat model we build in a VOID release pattern that transfers to the container, a frangible face that fragments on removal, a destructible inner ply, or a serialised panel hidden under a scratch layer.

We are honest about what this does: it makes tampering visible, it does not make it impossible. For high-value goods we combine the construction with serialisation so a scanned code can be checked against a database — the physical layer and the digital layer covering different attacks.
