pub const DEFAULT_POWER_DIP_FRACTION: f64 = 0.5;Expand description
Default beam-dip threshold as a fraction of the median power.
A dip is counted when the power PV drops below
power_dip_fraction × median(power). 0.5 sits between nominal
source jitter (a few percent around the median) and true beam-off
dips (power → 0), so it flags real outages without firing on noise.
