Additive (non-breaking): decide(factors=None) keeps the V3a base-only path (existing
11 tests unchanged); decide(factors=SizingFactors(...)) produces BLUE-complete
conviction via VioletSizer (base_max=8 + dc/regime(ACB)/ob/esof, capped@9) with the
full factor breakdown on ShadowDecision (base_leverage/dc_lev_mult/regime_size_mult/
market_ob_mult/esof_size_mult, None on the base path). SizingFactors value object =
the live-plane inputs the launcher will source (V3.4b). 6 new tests incl. consistency
vs VioletSizer, STALKER cap, EsoF-stale haircut. 17 pass.

Soak surfaced USDCUSDT being shorted. BLUE has a hardcoded exclusion gate around
its (muted-IRP) picking: _STABLECOIN_SYMBOLS removed from prices_dict pre-select
(nautilus_event_trader.py:24/3906). Replicate exactly: VioletDecisionEngine skips
the same 10 symbols in observe() so IRP never sees them. Following BLUE in all
regards (picking unchanged; this is BLUE's separate gate). Set-equality drift
guard vs BLUE source + never-selected test. 11 tests pass.
