I Luk Kim 8dacdaab4e Add v10 macro regime scoring (VIX+HY) and FRED macro features — SQS 59.1 (rejected)
New features:
- _enrich_macro_features() in snapshot_export: adds macro_vix, macro_hy_spread from FRED
- compute_return_max_long_score_v10: +12% bonus in favorable regime (VIX>18+HY>3.25)
- _macro_regime_score(): regime-aware scoring component

Findings:
- VIX signal is statistically strong: 62.3% WR (VIX>18+HY>3.25) vs 50.8% (other)
- But scoring bonus promotes marginal trades, diluting OOS quality
- Same pattern as eps_growth, drift bonus: raw signal ≠ scoring improvement
- v6new.17 SQS 59.1 < v6new.9 SQS 63.3

v6new.9 remains best at SQS 63.3 after 17 experiments.

I Luk Kim 85c4d98987 Add v6new experiment suite: scoring v8/v9/v9g, cross-event drift, coverage engines
Scoring additions (libs/backtest/scoring.py):
- v8: conditional financial bonus (eps_growth_qoq/revenue_growth_qoq)
- v9: cross-event drift momentum (+/-10% from prior same-ticker 5d return)
- v9g: gated variant — reject events with negative prior drift

Snapshot export (libs/export/snapshot_export.py):
- _enrich_prior_event_drift: computes prior_event_fwd5d for all snapshots
- smallcap-liquid-long-v1 universe profile ($500M-$2B)
- market_cap_max support in screener and filtering

8 experiment configs (v6new.1-v6new.8):
- v6new.1: unknown event reclassification (neutral)
- v6new.2: financial features (neutral, EPS growth is noise)
- v6new.3: small-cap (blocked, survivorship bias)
- v6new.4-6: cross-event drift variants (rejected)
- v6new.7: engine pruning (quality up, count down)
- v6new.8: coverage expansion with 2 new post-market engines (best result)

Best result: v6new.8 SQS 41.5 vs v6.29 control 32.3 on same conditions.

I Luk Kim 2395a0c0c3 feat: PEAD mid-cap strategy + pipeline hardening + README cleanup
- Implement PEAD 7% Long+Short strategy with mid-cap universe expansion
- Add Stock Oracle screener/company clients, text sentiment features
- Enhance backtest engine: short-side execution, walk-forward CV, MFE/MAE analysis
- Harden pipeline: sequential Oracle API calls, scoring recalibration (event_quality 65%)
- Add experiment configs for 60+ strategy variants and journal tracking
- Add review/analysis CLI tools
- Remove obsolete dev/phase0-4 design documents and analysis scripts
- Clean README to reflect only implemented features (remove unbuilt adapters/engines)

I Luk Kim 191653394d feat: scoring cleanup — alpha-only composite, default-deny unknown events, new exit/risk features
Remove 5 non-alpha features (earnings surprise, risk penalty, parse confidence,
direction clarity, LM sentiment) from composite score to eliminate double-counting
with hard gates and noise sources. Redistribute weights to 5 alpha features.

Add default-deny for unknown event types, no-follow-through early exit (D+1),
kill switch log-only mode, macro regime size scaler. Remove SUE gate (Gate 8).

I Luk Kim 4d0e773ba0 feat: overhaul strategy — document quality > price momentum
Flip scoring weights so event/document quality is primary signal (55%)
and market confirmation is secondary (35%). Add research mode with
kill-switch cooldown/reset, veto gates for bad events, reduced portfolio
risk, and 4 diagnostic analysis scripts.

Phase A: Research mode kill-switch reset, risk reduction (0.5%/trade,
max 4 positions), bullish-only direction for all event types.

Phase B: 2 new sub-scorers (parse_confidence, direction_clarity),
4 veto gates (oneoff risk, parse confidence, unknown/bearish direction).

Phase C: signal_quality, event_type_decomposition, kill_switch_impact,
concurrent_position analysis scripts.

I Luk Kim cdf6ae3493 feat: Phase 5 fundamental strategy improvements
Fix core strategy flaws identified from academic research and Phase 4
backtest results (23% win rate, 0% target hits, 77% stop exits).

5A — Exit mechanics: ATR-based targets (reachable ~4.5% vs unreachable ~6-8%),
     partial profit-taking at target with breakeven stop on remainder,
     wider catastrophic stop (3.0 ATR), trailing stop enabled by default.
5B — Event-type-specific logic: EventTypeProfile with per-type overrides
     for holding days, ATR multipliers, score thresholds, direction filter.
     Disabled management_change and other_material_event (low evidence).
5C-1 — Expanded universe from 15 to 97 symbols across sectors including
       mid-cap growth where PEAD is stronger.
5C-3 — Bootstrap 95% confidence intervals for key trade metrics.
5D — SUE integration: earnings surprise scoring (eps_growth_qoq) at 10%
     weight, entry gate blocks negative EPS surprise for earnings events.
5F — Extended label horizons to 10D/20D with Alembic migration.

I Luk Kim d4ae900286 feat: expand data pipeline and integrate event features into scoring
Data expansion:
- Poll SEC 8-K filings from 2025-10-01 to 2026-03-12 (was ~2 months)
- Pipeline: 36 new filings → 24 new events → total 44 events, 15 symbols
- Re-export with merged features (market_v1+event_v1+financial_v1)
- Parquet columns: 7 → 41 (adds signal_strength, guidance_direction,
  document_quality, oneoff_penalty, eps_growth_qoq, etc.)

Score model v2:
- Add event quality component (15% weight): signal_strength_score,
  guidance_direction_score, document_quality_score
- Add risk penalty component (10% weight): inverted oneoff_penalty
- Rebalance market weights: reaction 25%, close 25%, volume 15%, gap 10%
- Graceful degradation when event features are absent (returns 0.5)

Export pipeline:
- Add --feature-versions CLI flag to merge multiple feature types
- export_dataset_snapshot() accepts feature_versions list parameter
- Groups features by event_id and merges feature_json dicts

I Luk Kim 354f7a1716 feat: add rule-based entry score model for backtester
Replace naive abs(reaction_day_return) fallback with a composite score
from 4 market microstructure features available at entry time:

  1. Reaction quality  (35%) — moderate positive return (PEAD zone) is
     ideal; extreme positives penalized as "priced in"
  2. Close strength    (30%) — close near session high = buyers won
  3. Volume conviction (20%) — 1.2-2x is healthy; >3x is exhaustion
  4. Gap quality       (15%) — small positive gap = orderly strength

Real data results (14 events, b1868603 snapshot):
  - Score filters out 6 of 10 losers (DDOG -11.7%, META -9.1%, etc.)
  - With threshold 0.5: return -2.63% → +0.27%, drawdown 4.24% → 0.86%
  - Profit factor 0.44 → 1.16 (turns profitable)
  - MSFT loss (-8.7%) is macro-driven, not predictable from stock features
