TUI Hz fix:
- hazelcast_projection.py: write_engine_snapshot now writes all NAUTILUS-era
field aliases (trades_executed, current_leverage, open_positions as list,
last_scan_number, last_vel_div, vol_ok, open_notional) so gear_rows/capital
panel work with no TUI changes.
- dolphin_status_pink.py: _normalize_eng_for_tui() safety-net translation added;
render() uses it on every Hz read.
DC gate (SYSTEM BIBLE §4.2, champion config):
- pink_direct.py: _dc_contradicts() — 7-tick lookback, 0.75 bps threshold.
Rising price (chg > 0.75 bps) blocks ENTER via dataclasses.replace(HOLD, DC_CONTRADICT).
Price history deque initialized in connect(); dc_skip_contradicts=True enforced.
ACB boost (SYSTEM BIBLE §10):
- hazelcast_feed.py: fix wrong key "latest_acb" → "acb_boost" (DOLPHIN_FEATURES key
written by acb_processor_service.py).
- pink_direct.py: _last_acb_boost read from scan_payload["acb_boost"] first (scan
bridge may embed it), then Hz direct fallback. Applied to intent.leverage via
dataclasses.replace() after IntentEngine.plan(), capped at 3x.
- _last_scan_number, _last_vel_div, _last_vol_ok tracked from scan_payload.
OBF gate: NOT implemented. OBF shards (DOLPHIN_FEATURES_SHARD_*) require new
Hz map connections + symbol routing. Gap documented; requires separate decision.
Tests: TestDCGate (5) + TestNormalizeEngForTui (5) — 10 new, 104 total, all green.
