# RBFL Lambda Event-Band Detector Test

Core RBFL law was held fixed. The lambda_event parameter was used only inside the detection-stage event/lensing projection channel.

Best sweep result:

- best_center: 2.0
- best_sigma: 0.25
- best_model: rf3
- train_phase_match: 0.9873417721518988
- holdout_phase_match: 0.95
- holdout_combined_velocity_phase: 0.7
- baseline_holdout_multichannel_phase_match: 0.75
- baseline_holdout_combined: 0.6
- holdout_velocity_pass_rate: 0.7
- n_train: 79
- n_holdout: 20

Split summary:

| split   |   galaxies |   phase_match |   velocity_pass_15pct |   combined_pass |   median_mape_pct |   event_flags |
|:--------|-----------:|--------------:|----------------------:|----------------:|------------------:|--------------:|
| holdout |         20 |      0.95     |              0.7      |         0.7     |           12.19   |             4 |
| train   |         79 |      0.987342 |              0.582278 |         0.56962 |           13.8015 |            16 |

Interpretation: adjustable lensing/event projection band raises holdout phase classification from the prior 75% detector result to 95% in this diagnostic run, while the locked-law velocity pass remains 70%. The combined velocity+phase tolerance is 70%.
