VIC design session v97: best candidate (Q=6.7, 75.2kHz)

Sweep — screen-guided: live [Choke L (each), Turns], refined score 0.418

Cell — 12mm rod in 24.0mm tube × 100mm, 6 cell(s) parallel → C_eff = 3.85nF, bulk water R = 3774Ω.
Water/electrodes (Randles) — 2ppm Na+ @ 25°C, surface ×1 → λ_D 53nm, C_dl 197.8µF, cell series R 81.6Ω, displacement current 87.1%, breakdown margin ×445.
Vapor-film discharge (CGDE onset, 805V across 0.1mm film) — regime townsend-avalanche, film Paschen 719V, 321 Td.
Per-molecule (series micro-capacitor chain) — 22.22M molecules across 6.00mm → 36.25 µV/molecule (polarization (µV band)).
Chokes — 2 × 0.0005808785733563704H (20 turns, AWG 18, 2m wire, AC R 0.1Ω each).
At resonance f_r = 75.22kHz — Xl = 549Ω, Xc = 549Ω, tank Q = 6.7, coil Q = 3488.8.
Cell voltage 805V from 120V drive (×6.7). Tank current 1.47A circulating (CW upper bound — rate wire/switch for this); average input 29mA at 2% duty.
No hard violations (band, wire length, dielectric). Average current is scored, not gated.
Score 0.379.
