parity_harness.py: median-curve parity of V3a VioletBetSizer vs recorded
dolphin.trade_events (vel_div->leverage), restricted to short-signal domain.
GATE PASSES on prod host: pearson 0.9998, max_abs_err 0.238 (budget 1.0) over
23 bins -> base conviction sizer reproduces BLUE's central tendency. Per-trade
scatter is the deferred SC/ACB/OB/gold modulation layer (separate finding doc).
3 unit + 1 gate green.

90s BTCUSDT-PERP capture on the prod host, public data, dummy creds
(factory demands key env vars even for the data client; public endpoints
ignore the header). NT internal dispatch p50 0.23ms / p99 3.3ms — inside
VIOLET reactor budgets; 77 ticks/s sustained, zero drops. Qualifications:
NT owns its (uvloop) event loop -> recommended separate feed process
bridging via Zinc/HZ; exchange->cb p50 135ms is network+NTP+throttle, a
relative baseline only; PRODGREEN-era launcher API calls no longer exist
in 1.219 (FUTURES->USDT_FUTURE) — pin version + API smoke on adoption.
Exec-client spike remains keys-blocked; executor decision at the V4 gate.
