CIIL v6 is a preregistered computational investigation of accessibility structure in driven optomechanical systems using linearised quantum Langevin dynamics with rotating-wave and rotating frame consistent injection. The project examines whether accessibility between dynamical regimes is governed primarily by spectral admissibility and fluctuation content, or whether additional geometric and temporal transport structure emerges before conventional nonlinear or quantum thresholds activate. The study evaluates multiple structured drive families, including coherent, chirped, broadband stochastic, intermittent, phase coherent, frequency modulated, and null control drives under matched injected RF envelope normalization. Accessibility is analyzed through locked preregistered observables including δk*L persistence burden metrics, fluctuation admissibility measures, persistence weighted admissibility structure, corridor-excursion geometry, Rice crossing statistics, PCA accessibility manifolds, null-survival analysis, and accessibility isocontours. This v6 release represents the corrected and physically constrained extension of earlier CIIL v4/v5 exploratory runs. Major corrections include rotating frame consistent RF demodulation, κ/2 low-pass envelope extraction, removal of lab frame harmonic aliasing, explicit null model testing, locked figure provenance, preregistered prediction files, reproducible seed ensembles, and SHA-256 reproducibility locking. The primary result of CIIL v6 is that simple spectral admissibility and fluctuation only predictors do not fully determine accessibility ranking. Distinct drive families occupy structured regions of accessibility space despite weak scalar rank separation, indicating that accessibility behaves geometrically rather than as a one-dimensional burden coordinate. The results further suggest that excursion topology, burst organization, residence structure, and temporal localization contain information lost under scalar persistence compression. Structured intermittent drives produce disproportionately strong corridor excursions relative to continuous stochastic forcing under matched injected drive normalization, while accessibility organization emerges before conventional observables such as entanglement activation or strong DCE like threshold behavior. The manuscript explicitly separates established physics including quantum Langevin equations, rotating wave approximations, covariance dynamics, Rice crossing theory, and standard optomechanics from the project’s new contributions involving accessibility geometry, excursion topology interpretation, manifold organization, scalar compression failure, and preregistered falsification architecture. This release includes the full manuscript PDF, locked simulation code, prediction JSON files, sweep outputs, figure-generation pipeline, reproducibility metadata, SHA-256 integrity records, and all manuscript figures generated directly from locked outputs. The project is presented as an exploratory but reproducible investigation into pre threshold accessibility organization inside standard driven optomechanical dynamics, not as evidence for new fundamental physics beyond QED or optomechanics.
