gahusb	2aa9f48ea3	feat(signal_v2-phase4): add emit/skip logging to signal_generator ... logger was declared but unused. Operational visibility was zero — trader debugging 'why no signal?' had to step through code mentally. - INFO on emit: '[signal emit] 005930 buy conf=0.823 rank=3' / sell with reason - DEBUG on each skip path: same-cycle sell, hard gate, low confidence, dedup 24h (buy and sell) Per final reviewer recommendation. 56 tests still pass.	2026-05-17 13:35:29 +09:00
gahusb	e574074ca8	fix(signal_v2-phase4-task2): code review fixes — sell-first ordering + anomaly test + defensive .get ... - generate_signals now evaluates sell before buy; buy candidates with a same-cycle sell signal are skipped (resolves silent overwrite of state.signals[ticker]). - Added test_sell_signal_triggers_on_anomaly_path covering _try_anomaly path (previously 0% covered). - Fixed stale test comment referencing deprecated relative spread formula. - _check_buy_hard_gate uses dict.get(..., 0) for defense against partial upstream state. - _compute_buy_confidence clamps screener_norm to >= 0 for future Top-N changes.	2026-05-17 13:18:22 +09:00
gahusb	b9def06993	feat(signal_v2-phase4): signal_generator + 9 unit tests ... generate_signals(state, dedup, settings) → state mutating: - Buy: screener Top-N + portfolio. Hard gate (chronos median > 0 + spread < 0.6 + momentum strong_up + bid_ratio >= 0.6) + soft confidence (chronos*0.5 + minute*0.3 + screener*0.2) > 0.7. - Sell: portfolio only. Priority stop_loss > anomaly > take_profit. Stop loss confidence 1.0, take_profit 0.6 (review alert). - SignalDedup 24h via dedup.is_recent/record per (ticker, action). - State signal dict matches Phase 0 spec §5.2 schema. 54 tests pass.
