I Luk Kim bc4ffecb10 Add v6new.275: SQS 72.7 #1, CW 312.6% — OME early fail day 1
OME engine early_failure_no_progress_days=1 (from day 2 in v272) further
improves capital recovery speed. 198 trades, 312.6% CW return.

SQS 72.7 = new #1 on leaderboard (including overlays).
Test return +45.5%, Profit Factor 19.23.

Key: cutting OME losers at day 1 instead of day 2 frees capital faster
while losing only marginal OME winners that needed >1 day to show progress.

I Luk Kim 165424ecc2 Add v6new.272: CW 310.8% breakthrough via OME early failure cut
Trade analysis revealed OME engines had 54-60% WR with stop-heavy exits.
Adding early_failure (day 2, R=0.0) for OME engines frees capital faster,
enabling 6 more trades (194→200) and boosting CW from 293.2% to 310.8%.

Key insight: cutting low-quality engine losers early improves compounding
more than any scoring/feature/sizing change tested in this session.

v6new.272: SQS 72.4 (#6), CW 310.8%, 200 trades, test +44.9%

I Luk Kim 1c38415cb7 Add v6new.265-268: small-cap expansion experiments
Lowering market cap floors to 2B added 15 trades (194→209) but CW return
dropped from 293.2% to 278.5%. Small-cap PEAD events have lower average
quality — individual outliers like SEDG exist but don't compensate.

v6new.255 (293.2%) confirmed as optimal trade-quality balance.

I Luk Kim e2229646e6 Add oversold bounce engine experiments (v6new.259-264) — blocked by architecture
Bounce engine (buy negative reaction, bet on mean reversion) could not
execute: system architecture ties scoring to single model per backtest,
and selector/store indexes are optimized for positive-reaction PEAD.
Negative-reaction candidates get score=0 from PEAD scoring, blocking
engine selection regardless of engine-level threshold overrides.

Implementing bounce trades requires: dual scoring model support,
selector changes for negative-reaction candidate routing, and
store indexing changes. Deferred to future refactor.

Current best CW return: 293.2% (v6new.255)

I Luk Kim 74244b15d2 Add v6new.224-258: grid search risk×ATR toward 300% CW
Best: v6new.255 (293.2%) = risk 0.069 + ATR 1.45 + entropy + doc 0.50
ATR 1.45 is critical threshold — below it loses 1 trade and drops to 269%.
Risk 0.069 is max before trade loss at 0.070.

Progress: 262.9% → 284.4% → 288.3% → 290.4% → 291.8% → 293.2%

I Luk Kim 672098c077 Add v6new.215-223: three-way parallel search toward 300% CW
Best: v6new.220 (289.6%) = risk 0.065 + max_pos_value 1.5 + ATR 1.6.
194 trades fixed — event count is the structural bottleneck.
Management_change/oneoff relaxation hurt. Budget/leverage neutral.
300% requires fundamentally more trades or higher per-trade returns.

I Luk Kim 6dee2c24d2 Add v6new.197-214: parameter grid search around v196
Best CW return: v6new.207 (288.3%) = v196 + risk 0.060 + ATR 1.6.
Public SQS: v6new.196 (72.6) still best — v207 is 72.5.
ATR 1.6 is optimal stop distance. Sector limit increase hurts badly.

I Luk Kim cc953949f1 Add v6new.196: new best SQS 72.6 (#3) — v29+entropy+risk+doc_quality
v6new.196 = v29 base + entropy scoring (v13e) + per_trade_risk 0.058
+ doc_quality 0.50. CW return 284.4% (+21.5pp over v122), 194 trades.

Key finding: v29 base with doc_quality 0.50 (not 0.55) is the optimal
quality gate when combined with entropy scoring.

I Luk Kim 090bfa8e36 Add contrarian feature analysis + v15 scoring (v6new.174-188)
Data analysis revealed OBV Q1 (distribution) has 56.4% WR vs Q5 51.2% —
contrarian signal confirmed. Previous OBV bonus was applied in wrong
direction. Corrected with v15 scoring models.

Best result: v6new.185 (entropy + risk 0.058) CW 274.4% but SQS 72.2,
still below v6new.122 (72.4). WFV/robustness offsets CW gains.

v6new.122 confirmed as optimal under current SQS v4 formula.

I Luk Kim 1e66b67c7a Add technical/scientific feature experiments (v6new.106-173) and v6new.122 SQS 72.4
Tier 1: Vol/RSI/BB/OBV features — sizing scalers hurt public SQS, scoring
adjustments ineffective on 28-30 trades. Only doc_quality gate lowering
(0.66→0.55) improved results (+2 trades, +0.8 SQS).

Tier 2: Hurst exponent, Shannon entropy, sector momentum — entropy bonus
CW +10.7pp but SQS equivalent (72.3 vs 72.4). Sector momentum hurt badly.

Tier 3: OU theta, gravitational pull, market temperature — all caused
large CW return drops (-80 to -103pp). Physics-based indicators don't
fit event-driven PEAD.

Best result: v6new.122 (SQS 72.4, #3 leaderboard) = v6new.29 + doc quality
gate 0.66→0.55. Single parameter change outperformed all feature engineering.

New code:
- libs/features/market_features.py: 9 new features (vol, RSI, BB, OBV,
  Hurst, entropy, OU theta, gravitational pull, market temperature)
- libs/backtest/scoring.py: v12-v14 scoring models with technical gates
- libs/backtest/allocator.py: volatility + conviction size scalers
- libs/backtest/domain.py: volatility_size_scaler + conviction_boost config
- scripts/enrich_*.py: snapshot enrichment scripts
- 68 experiment configs (v6new.106-173)

I Luk Kim daa8536546 Add v6new.36: mean reversion engine for high-VIX drops
New engine: next_open_long_mean_reversion_high_vix
  Targets: react < -7%, close 0.15-0.60, bearish/mixed/unknown direction
  Signal: VIX>20 + big drop = 62.9% WR, +3.91% 5d mean (n=167)
  VIX 25-30 sweet spot: 75% WR, +5.46% 5d mean

Test split: 3 MR trades, 67% WR, +5.59% total PnL
Paper BT: 51 trades vs 48 (v6new.30), return ~equal

Also fixes _rows_to_table to handle sparse feature columns.

I Luk Kim e8241d2924 Test execution model + short side — both rejected, v6new.30 confirmed
Short Side (Direction 3):
  Bearish events: 45-55% WR for short — no actionable edge
  Mean reversion after large drops cancels short PEAD

Execution Model (Direction 2):
  T+2 delayed entry: loses 54% of alpha (Day 1 = 54% of 5d return)
  Wider stops (v6new.34): -0.68pp — smaller positions offset fewer stop-outs
  Tighter trailing (v6new.35): -12.48pp — cuts winners too early
  reaction_close >> next_open (86% vs 57% WR) but post_market can't use RC

Direction 1 (new data: Form 4, XBRL, Earnings Surprise) requires Oracle API
implementation. Free sources identified: SEC EDGAR, Alpha Vantage, FINRA.

v6new.30 is the confirmed framework optimum.

I Luk Kim 85515f2db9 Add v6new.31-33: parameter tuning — all neutral/worse, v6new.30 confirmed optimal
v6new.31 (all OME risk reduced): +105.23% — worse, mixed_ome/other_material_mixed need full risk
v6new.32 (patient risk only): +108.15% — marginal, not worth
v6new.33 (core warmup 10): +108.62% — identical to v6new.30

v6new.30 (+108.62%, Sharpe 3.77, SQS 63.8) is the framework optimum.
Further parameter tuning yields diminishing/negative returns.

  - other_material_unknown: 0.005→0.003
  - unknown_ome: 0.012→0.008

I Luk Kim 7a2001a4fa Add v6new.25: OME risk halved — paper BT +94.38% beats v6.29 +93.60%
Based on paper backtest loss analysis (not backtester SQS optimization):
- OME engines contribute only +$1,405 on 8 trades but generate most losses
- Halving OME per_trade_risk reduces loss magnitude without removing trades
- Paper BT: +94.38% vs v6.29 +93.60%, MaxDD 4.07% vs 4.60%
- WFV: 100% positive fold rate (worst +0.02%)
- RM worst: -0.88%, OOT worst: -0.33%
- SQS: 62.9 (vs v6.29 62.8)

This is the first strategy improvement validated by BOTH backtester SQS
AND paper backtest return, using the now-unified engine systems.

I Luk Kim bb659cf7ae Add reaction-based position sizing to reduce mean-reversion loss risk
New feature: reaction_size_cap_threshold in RiskConfig
- When abs(reaction_day_return) > threshold, position size scales down
- Formula: scaler = threshold / abs(reaction) (linear inverse)
- E.g. threshold=8%: 8% reaction → 100%, 16% → 50%, 24% → 33%

Paper trading impact simulation (top 10 trades):
- PII (react +14%): loss $501 → $288 (saved $214)
- VSCO (react +18%): loss $792 → $350 (saved $442)
- RYTM (react +12%): loss $397 → $256 (saved $141)
- Winners (react <5%): unchanged (SSRM, FLS, LW, KGS all 100%)
- Total loss reduction: $2,610 → $1,813 (-30%)
- Net PnL improvement: +$797

v6new.24 backtest: Train SQS 92.5 (session best), risk=75.6.
Public SQS 52.5 (lower return due to sizing, but best risk profile).

I Luk Kim 89e5b647b0 Add v6new.23: OME risk halved + vol/reaction gates — SQS 62.3, best loss profile
v6new.22 + additional loss reduction:
- OME engine risk halved (per_trade_risk * 0.5)
- Volume minimum raised to 1.0 (blocks LKQ vol=0.8)
- Guidance reaction_min raised to +1% (blocks SEIC react=0.5%)

SQS 62.3 (up from 61.9 in v6new.22). Train SQS 91.6 (session best).
OOT worst window -0.31% (session best). Test +55.22%.
Trades 90 (down from 106) — quality over quantity.

Paper trade impact: blocks ALL major losses (TEM, PII, ORCL, FND, LKQ, SEIC).
This is the recommended config for live deployment.

I Luk Kim 60da697d54 Add v6new.22: paper trade loss fixes — SQS 61.9 but blocks $1.5K live losses
Targeted fixes from paper trading analysis:
- Recovery engine: reaction_min -0.10→-0.03 (blocks PII -5.3% reaction)
- Broad oneoff: close_min 0.30→0.40 (blocks TEM 0.38, FND 0.37 low close)
- Guidance: close_max 0.93 (blocks ORCL 0.94 exhaustion)

Result: SQS 61.9 (< v6new.9 63.3) due to trade count 118→106.
However, these fixes would have prevented ~$1,500 in paper trading losses
(TEM -$541, PII -$402, ORCL -$386, FND -$129).

Trade-off: historical SQS vs live loss prevention. The gates are correct
for live trading even if they reduce backtest SQS.

I Luk Kim 3c13c9e1b5 Add vix_pead regime sizing mode and macro experiments (v6new.19-21)
New in allocator.py:
- vix_pead mode: boosts sizing at VIX>18 (PEAD favorable), penalizes VIX 15-18
- Fixed vix_scaler application to support boost (scaler > 1.0)

Results:
- v6new.19 (spy_qqq risk_off=0.55): SQS 62.8 — reduces size in favorable PEAD regime
- v6new.21 (vix_pead boost+penalty): SQS 46.9 — penalty too aggressive, kills trades

VIX signal is real (62.3% vs 48.2% WR) but sizing alone can't capture it:
- Boosting doesn't help because same trades just get bigger
- Penalizing shrinks or drops trades, losing count
- Need the signal in TRADE SELECTION, not just sizing

v6new.9 (SQS 63.3) remains best.

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.

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 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%

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

I Luk Kim 867d70afae fix: correct simulation loop and equity curve calculation after real-data testing
- BacktestRunner.run() now iterates all NYSE trading days (not just candidate
  days) via SnapshotStore.all_trading_days() so stop/target/time exits are
  checked every day, not only on days with new candidates
- Record initial DailyPortfolioState before simulation loop starts so
  total_return_pct is computed relative to the true initial equity (100k),
  not the first post-entry equity snapshot
- SnapshotStore._fetch_event_metadata() now synthesises event_timestamp from
  event_date + 21:00 UTC when filed_at_utc is NULL (transparent enrichment at
  loader boundary, not silent substitution in selector)
- SnapshotStore._async_load() maps event_close → entry_price_est when the
  column is absent, and derives score from abs(reaction_day_return) when the
  Parquet snapshot has no score column
- Add --snapshot-dir CLI flag to BacktestRunner to override the default
  parquet_dir base path (needed for non-standard snapshot locations)
- Fix integration test assertion: total_trading_days >= 2 (was == 2)
- Add configs/experiments/realdata_test_v1.json for real Phase 3 snapshot runs

I Luk Kim 2f4d9f61f7 feat: implement Phase 4 -- event-driven backtester
Full backtesting engine that reads Parquet snapshots and simulates a
swing-trading strategy with no look-ahead bias.

## New modules (libs/backtest/)
- domain.py: All Pydantic v2 models (Candidate, PlannedOrder, FilledTrade,
  OpenPosition, DailyPortfolioState, MetricsBundle, BacktestConfig, etc.)
- calendar.py: Thin wrappers over time_utils + reaction_date
- manifests.py: Config load/deep-merge/validate, run-ID generation
- metrics.py: 21 pure-function metrics (no pandas, stdlib statistics only)
- selector.py: build_candidate(), rank_candidates() (score↓ ADV↓ symbol↑)
- allocator.py: 7-gate run_entry_gates(), ATR stop, floor() shares
- execution.py: simulate_entry/exit(), update_trailing_stop() (ratchet-up only)
- splits.py: Walk-forward windows, year/regime split utilities
- snapshot_store.py: Sync load() → asyncio.run(_async_load()), no look-ahead
- artifacts.py: Full run-dir writer (Parquet, CSV, JSON)

## App modules (apps/backtester/)
- run.py: BacktestRunner (exit-first→entry simulation, 25% kill switch) + CLI
- replay.py: Double-run determinism checker

## Config files
- configs/backtest/defaults.json: Base strategy defaults
- configs/experiments/baseline_v1.json: First experiment manifest

## Tests: 142 new tests, all passing
- 132 unit tests (no DB/HTTP required)
- 8 integration tests (synthetic SnapshotStore)
- 3 backtest determinism/replay tests
