### Iteration 1
- DSL: `(i_rsi(k_close, 14) - 50) * k_high.pct_change(12)` (feature=k_loop_iter_1_f3389e)
- DSL valid: True
- FeatureSet candidate id: 679
- baseline PF: 1.286 → modified PF: 1.360
- t_stat: 0.000, p_value: 1.000, cohens_d: 0.000
- scalar_score: 0.4154
- accepted: True, reason: accepted

**Metrics summary:**
  - profit_factor: baseline=1.286, modified=1.360, diff=0.075
  - sharpe_ratio: baseline=7.879, modified=9.490, diff=1.611
  - win_rate: baseline=0.553, modified=0.519, diff=-0.034

  - test_accuracy: baseline=0.986, modified=0.986, diff=0.000

### Iteration 2
- DSL: `(i_rsi(k_close, 14) - 50) * i_atr(k_high, k_low, k_close, 10) / k_close` (feature=k_iter_2_i_rsik_close, 14) - 50) * i_atrk_high, k_low, k_close, 10) / k_close)
- DSL valid: False
- FeatureSet candidate id: None
- baseline PF: 0.000 → modified PF: 0.000
- t_stat: 0.000, p_value: 1.000, cohens_d: 0.000
- scalar_score: 0.0000
- accepted: False, reason: safe_eval DSL produces inf when ['k_close'] is zero; avoid unprotected division by these variables
