Operator directive: VIOLET must do IDENTICALLY what BLUE does for the three parity
flags — approximation cannot guarantee bit-for-bit functioning. Reworked
live_blue_source.py to call BLUE's OWN code paths, not reconstruct/substitute them.
boost/beta — was reading the published DOLPHIN_FEATURES.acb_boost scalar
(acb_processor_service's daily value). BLUE's trader does NOT use that for sizing; it
recomputes live via acb.get_dynamic_boost_from_hz(exf_latest, w750_velocity, direction)
with a bare AdaptiveCircuitBreaker() and NO ob_engine (nautilus_event_trader.py
on_exf_update:4769 / rollover prewarm:2710). New _source_boost_beta replicates that call
exactly (reads exf_latest + latest_eigen_scan.w750_velocity; 0.0→None like BLUE; on stale
exf ValueError → neutral, mirroring BLUE's "ACB Stale Data Fallback"). The published
acb_boost is never read. Test pins bit-identity against the real ACB.
signal-gen (dc_status) — was AlphaSignalGenerator() bare defaults; coincidentally equal to
BLUE today, but BLUE builds it from ENGINE_KWARGS (trader:128-133, threaded at
esf_alpha_orchestrator.py:180-191), so a champion retune would silently diverge. Now
constructed with BLUE_SIGNAL_GEN_KWARGS (vel_div_* imported from the kernel constants).
Test parses ENGINE_KWARGS from the trader source and asserts each param matches — drift
becomes a red test, not a silent miss.
OB — was a reinvented HazelcastOBProvider reading asset_*_ob with custom parsing. Now uses
BLUE's OWN HZOBProvider + OBFeatureEngine, wired exactly as _wire_obf
(nautilus_event_trader.py:4967-4980): step_live(assets, bar_idx) then get_market. Engine
is injectable + persistent so OB accumulation matches BLUE across scans (caller owns it).
Deleted: HazelcastOBProvider, _extract_acb, the status-label mc path. mc_scale fix
(begin_day cat/env thresholds) retained. Module docstring + structural-divergence doc
updated: all three flags FIXED; only _derive_mc_scale remains hand-replicated (pinned by
formula test). OPEN follow-up: launcher shadow_decision_step should pass a persistent
ob_engine + bar_idx for cross-scan OB history.
34 tests (33 + live-HZ smoke deselected): boost/beta-vs-ACB bit-identity (incl. w750=0→None,
no-exf, stale ValueError, ignores acb_boost), signal-gen ENGINE_KWARGS pin (parametrized),
OB wiring (step_live call, HZ coords, neutral paths), mc_scale formula, sequence dc/selector
parity, anomaly handling. violet-only; no shared-file edits.
