Claims are made at property level: what the hardware provides, what it resists, and how it integrates. Mechanism, circuit architecture and implementation detail are not published, and no useful buyer decision depends on them being published.
Language is chosen with the same care. Tamper-evident is described as tamper-evident, and not escalated to the stronger word. No system is described as impossible to attack. Where a claim depends on an assumption or a configuration, the assumption is stated.
Detailed technical discussion happens under a non-disclosure agreement, where the mechanism, the threat model and the evaluation evidence are all available.
