A fixed causal biquad and trailing power window estimate band-power change from a frozen baseline. The result is an ERD proxy, not a clinical movement-intention diagnosis. Explicit signal-timestamp intervals must remain within five percent of the declared sampling interval.
Usage

- power_window_samples
Trailing causal mean-square window length.
- enter_percent, release_percent
ERD enter/release percentages.
- min_on_samples, min_off_samples
Consecutive confirmation counts.
- min_baseline_power
Minimum accepted frozen baseline power.
