Ontological Resolution Theory (ORT) — Canon v8.0: Time as Ticks, Gravity as Computational Load, and a Spectral-Invariant Bridge for Z

ORT is an axiomatic meta-framework for operational reality under finite observer capacity. Canon v8.0 introduces an explicit two-layer discipline separating a micro layer (discrete ticks and lattice operators) from an effective layer (continuum PDE used as conversion tables). The geometric impedance parameter Z is retained as an empirical ansatz, while a concrete microscopic derivation target is introduced via canonical FCC spectral invariants (trace-per-unit-volume and lattice Green function / Watson integral). Gravity is treated as inhomogeneity in local tick rate induced by computational load; Poisson/Lag behavior is adopted as weak-field effective closure with explicit micro-derivation targets. Strong-field behavior is parameterized by the tick-permission factor U=(Ω/Ω0)2 and related hypotheses. The mapping from Z to α−1 is stated as a leading-order empirical bridge with precision-status accounting. A roadmap of falsification criteria and open derivation problems is included.
