Deep Quantum Characterisation of the Vibration → Light → Mass-Threshold Chain via Cavity Optomechanics and the Dynamical Casimir Effect

This record contains the complete data, code, figures, and sealed manifests for the CIIL v4 QED Full registered exploratory study. The study presents a comprehensive preregistered quantum characterisation of the Constraint Induced Identity Locking (CIIL) cascade operating in a physically grounded cavity-optomechanical system parameterised by the Teufel et al. (2011) aluminium drumhead experiment and the Wilson et al. (2011) Dynamical Casimir Effect circuit. Seven distinct mechanical drive geometries (V-types) at matched mean energy are characterised using the linearised quantum Langevin equation framework the standard theoretical formalism of cavity optomechanics across three independent pre-declared random seeds (42, 1234, 99999), with 200 trajectories per V-type per seed and 40+ physical observables per run spanning the vibration (V), photon field (L), and DCE threshold (M) regimes. Principal findings: Nine of twelve pre-declared hypotheses pass in every seed. The null separation partition four V-types with temporal modulation structure cleanly distinguished from the structural null, three falling inside the null distribution reproduces identically across all three seeds. The cascade burden δk*_L spans a 3.05-fold range from the stochastic broadband (V5) to the multi-harmonic (V4) drive geometry, and the downstream DCE pair production rate spans an 18-fold range over the same V-types at identical cooperativity and temperature. A previously unrecognised inverse relationship between spectral transfer efficiency H(ωm) and cascade burden quantifies the cavity's bandpass-filtering role in the V→L transition. The two hypothesis failures (zero logarithmic negativity E_N and near-zero DCE squeezing r_sq) are physically explained by the thermal bath dominance at the reference operating point (n̄_th = 29.1 at 15 mK, C = 100) and sub-threshold DCE operation respectively; both are consistent with the correct predictions of the Vitali–Serafini Lyapunov formalism and the Johansson et al. parametric amplification formula.
