``` bash
cc-steer compare-arms REPORT_A REPORT_B
```


Pairs the reports' per-row probs on the frozen watcher frame and prints the card verdict -- an actionable gain or regression with its CI and measured rho, or `within noise floor (MDE <value>)`. A report predating per-row persistence falls back to the card's unpaired frame MDE.
