PHILIA-EcoSensory Swarm v53: Beyond Single-Axis Control — y(w) Independence and the Necessity of Dual-Axis GearboxY in Recursive Multi-Agent Systems

We present PHILIA-EcoSensory Swarm v53, a pre-registered 4-cell ablation study (400 runs, N=20 seeds, seeds 362–381, T=80,000 steps) determining whether y(w) — the coexistence coordinate of the PHILIA Phase Vector — is a z-cascade variable or an independent control axis. Building on v52+'s SkewedBell geometry of z(w) (R²=0.9990, ΔAIC=97.35 vs. linear, DOI: 10.5281/zenodo.19947800), v53 Phase 1 implements a pre-registered 4-cell ablation (Red Team 0번 관문 11/11 PASS):- cell_A: GearboxZ ON, GearboxY OFF (key verdict cell)- cell_B: GearboxZ OFF, GearboxY ON- cell_C: GearboxZ ON, GearboxY ON- cell_D: control Primary finding: cell_A yields Y_res = 0.0163 ± 0.0013 (95% CI), CONDITIONAL verdict. Five independent lines of evidence — y/z recovery ratio 0.057, cell_A y-range 78% of control, additive effect decomposition (Z: +0.0050, Y: +0.0131, synergy: −0.0039) — are consistent with a weakly coupled independent mechanism. cell_C (Z+Y) achieves Y_res=0.0071, Y_max=0.0045, near-complete PHI_NATURAL restoration with zero over-correction. GearboxY is a necessary independent control module. Exploratory post-hoc analysis reveals x-axis drift under GearboxZ intervention (|x−0.34|_max=0.0247 vs. free-swarm baseline 0.0056), consistent with COUPLE_XZ linear cross-coupling. Pre-registered validation deferred to future work. Hardware: AMD Ryzen 9 9800X3D + RTX 4080 SUPER 16GB. Substrate: CERN dielectron + ATLAS Higgs + NYC Taxi.
