WFC design session v28: best candidate (Q=23.9, 30.3kHz)
Sweep: Attack 150 Td cold-window from the density side — cold low-ppm high-εr water pins f_r and raises N while wider gap/longer electrodes drop the field, co-swept with peak_v/duty for <200mA average draw.
Cell: 12mm rod in 24.0mm tube × 100mm, 6 cell(s) parallel → C_eff = 4.19nF, bulk water R = 44446Ω. Water/electrodes (Randles): 0.1ppm Na+ @ 2°C, surface ×0.5 → λ_D 227nm, C_dl 25.6µF, cell series R 35.5Ω, displacement current 97.3%, breakdown margin ×280. Vapor-film discharge (CGDE onset, 1434V across 0.1mm film): regime streamer, film Paschen 719V, 572 Td. Per-molecule (series micro-capacitor chain): 22.22M molecules across 6.00mm → 64.54 µV/molecule (polarization (µV band)). Chokes: 2 × 0.0033H (1350 turns, AWG 22, 161m wire, AC R 8.5Ω each). At resonance f_r = 30.26kHz: Xl = 1255Ω, Xc = 1255Ω, tank Q = 23.9, coil Q = 73.7. Cell voltage 1434V from 60V drive (×23.9). Tank current 1.14A circulating (CW upper bound — rate wire/switch for this); average input 23mA at 2% duty. No hard violations (band, wire length, dielectric). Average current is scored, not gated. Score 0.695.
