STRUC-I is a structural interrogation engine. It evaluates how ordered numerical structures respond to perturbations and tests whether their internal ordering remains admissible.
It operates on ordered ladders — sequences such as:
The chamber is domain-agnostic. It operates on the geometry of ordering — not on the physical domain.
STRUC-I evaluates the Universal Structural Law:
inv(Pε ; L) ≤ ν(Vε(L))
across preregistered ordered ladders. inv counts perturbation-induced rank inversions; ν is the maximum independent set of the vulnerability graph. No perturbation scale and no physical domain is excluded a priori — the chamber is a falsification engine.
Three regimes: ■ Geometric Persistence (ρ < 0.60, Aκ=1) · ■ Structural Boundary (ρ 0.60–1.0) · ■ Structural Instability (ρ > 1 or Aκ < 1).
