Frame Constitution and Identity Tolerance: The Determination of δ_F in La Profilée

The Paper "Existence witout Identity" established the Frame Continuity Condition (FCC) as the identity complement to LP’s existence condition IR ≤ 1. FCC requires that Frame drift from origin does not exceed identity tolerance δ_F. The present paper addresses the determination of δ_F. We argue that δ_F is neither empirically stipulated nor universally fixed, but structurally derived from a distinction internal to Frame itself: F_constitutive, the identity-bearing core of the Frame, and F_operational, its variable expression. δ_F is the maximal displacement of F_operational compatible with F_constitutive remaining intact. This derivation makes δ_F system-relative without making it arbitrary, and operational without requiring external calibration. The result extends LP’s measurement program to the identity dimension and closes the determination problem opened by FCC.
