Detailed Description

Computed accuracy, robustness, and drift metrics per EU AI Act Art.15.

Art.15(1): Accuracy metrics appropriate to the system's intended purpose. Art.15(3): Resilience against errors, faults, and inconsistencies. Art.15(4): Cybersecurity posture (addressed at infrastructure level).

Defined at namespace scope for Apple Clang compatibility.
