WFC design session v36: best candidate (Q=47.6, 91.9kHz)
Sweep: Hold #1's 12/16mm cell but attack Paschen from the water side — sweep gap, temperature and purity to lower the film breakdown voltage so a modest V_cell (24-42V drive, moderate duty) lands inside 80-250 Td without extinguishing, trading R_ct leakage against the cold/pure floor rather than just trimming peak_v.
Cell: 12mm rod in 16.0mm tube × 100mm, 1 cell(s) parallel → C_eff = 1.67nF, bulk water R = 80377Ω. Water/electrodes (Randles): 0.2ppm Na+ @ 4°C, surface ×0.4 → λ_D 161nm, C_dl 4.1µF, cell series R 13.4Ω, displacement current 98.7%, breakdown margin ×116. Fig-8 voltammetry (4,798,661): τ_EDL 327884.4µs (30132.0 carrier cycles to charge), Faradaic leakage at peak 98.5mA (leak score 0.50 — keep amp leakage inhibited while voltage climbs the ladder). Vapor-film discharge (CGDE onset, 1143V across 0.1mm film): regime townsend-avalanche, film Paschen 719V, 456 Td. Per-molecule (series micro-capacitor chain): 7.41M molecules across 2.00mm → 154.34 µV/molecule (polarization (µV band)). Chokes: 2 × 0.0009H (520 turns, AWG 22, 62m wire, AC R 4.2Ω each). At resonance f_r = 91.90kHz: Xl = 1039Ω, Xc = 1039Ω, tank Q = 47.6, coil Q = 124.1. Cell voltage 1143V from 24V drive (×47.6). Tank current 1.10A circulating (CW upper bound — rate wire/switch for this); average input 33mA at 3% duty. No hard violations (band, wire length, dielectric). Average current is scored, not gated. Score 0.691.
