WFC design session v30: best candidate (Q=13.3, 45.7kHz)
Sweep: Freeze near-v19 tank geometry but attack the Td window directly with a fine electrode-gap × length ladder crossed against a low-mid drive ladder (3-10kV V_cell), holding water cold/pure to raise R_ct and Q while nudging gap to slide the 0.1mm vapor film into 80-250 Td.
Cell: 16mm rod in 25.6mm tube × 90mm, 6 cell(s) parallel → C_eff = 5.51nF, bulk water R = 8517Ω. Water/electrodes (Randles): 1ppm Na+ @ 5°C, surface ×1 → λ_D 72nm, C_dl 175.7µF, cell series R 47.1Ω, displacement current 93.1%, breakdown margin ×384. Fig-8 voltammetry (4,798,661): τ_EDL 1496451.5µs (68393.6 carrier cycles to charge), Faradaic leakage at peak 1335.5mA (leak score 0.00 — keep amp leakage inhibited while voltage climbs the ladder). Vapor-film discharge (CGDE onset, 800V across 0.1mm film): regime townsend-avalanche, film Paschen 719V, 319 Td. Per-molecule (series micro-capacitor chain): 17.78M molecules across 4.80mm → 44.97 µV/molecule (polarization (µV band)). Chokes: 2 × 0.0011H (20 turns, AWG 22, 2m wire, AC R 0.1Ω each). At resonance f_r = 45.70kHz: Xl = 632Ω, Xc = 632Ω, tank Q = 13.3, coil Q = 2200.4. Cell voltage 800V from 60V drive (×13.3). Tank current 1.27A circulating (CW upper bound — rate wire/switch for this); average input 25mA at 2% duty. No hard violations (band, wire length, dielectric). Average current is scored, not gated. Score 0.512.
