Core Mechanism
Structural necessity disguised as structural impossibility through systematic concealment of load-bearing mechanisms and amplification of void-reading cues.
Kernel Engagement
Works within the kernel’s native ground; the structural gap is present but never encountered.
Evidence
The pendentive geometry solves the required engineering problem of placing a circular dome on a square base, while the perimeter dematerialization and material gradient are structural necessities disguised through surface treatment and aperture strategy.
Territory
The extraordinary structural engineering (pendentives, material lightening) was required by the chosen span and program, not chosen as content. The announced subject is divine transcendence through dematerialized space - structure resolves gravity and disappears per the necessity exposure principle.
Constitutive depth
The work operates within gravity's constraints without generating endogenous structural consequences. The pendentive solution, material lightening, and load distribution strategies are responses to the chosen program (dome on square base) rather than constraints generated by the mechanism itself.
Legibility
The structural system is systematically concealed through 'structural necessity disguised as structural impossibility' - load-bearing mechanisms are hidden while void-reading cues are amplified. The audience experiences floating divine space, not structural performance.
