WFC design session v29: best candidate (Q=101.2, 99.4kHz)

Sweep: Lock in v19 tank under drive-duty-v3: Chris-approved 120V low-duty bench point (12.1kV cell at ~196mA average) — exact v19 cell + 0.99mH/129T choke pinned, drive ladder around 120V/2%

Cell: 15.9mm rod in 25.5mm tube × 127mm, 1 cell(s) parallel → C_eff = 1.29nF, bulk water R = 137985Ω. Water/electrodes (Randles): 0.1ppm Na+ @ 3°C, surface ×0.25 → λ_D 227nm, C_dl 3.3µF, cell series R 11.1Ω, displacement current 99.1%, breakdown margin ×32. Vapor-film discharge (CGDE onset, 10121V across 0.1mm film): regime streamer, film Paschen 719V, 4036 Td. Per-molecule (series micro-capacitor chain): 17.78M molecules across 4.80mm → 569.31 µV/molecule (polarization (µV band)). Chokes: 2 × 0.00099H (129 turns, AWG 18, 15m wire, AC R 0.6Ω each). At resonance f_r = 99.41kHz: Xl = 1237Ω, Xc = 1237Ω, tank Q = 101.2, coil Q = 1090.3. Cell voltage 10121V from 100V drive (×101.2). Tank current 8.18A circulating (CW upper bound — rate wire/switch for this); average input 82mA at 1% duty. No hard violations (band, wire length, dielectric). Average current is scored, not gated. Score 0.845.
