Struct DiskBusyRule 

pub struct DiskBusyRule { /* private fields */ }

A block device busy for a sustained period (§11.2).

Why this rule reads the radar instead of counting history

History retains device throughput, not the busy share (§8.5) — a busy percentage per device per sample would grow every retained sample with the machine’s device count. The sustained-ness of device busy is therefore established by the hysteresis the PressureEngine already applies to the disk signal, and this rule reports it with the evidence the engine kept. The consequence is an ordering requirement, documented on the engine: pressure must be derived before the rules run. Until it is, the signal is warming up and this rule stays silent — which is the correct answer, not a missed detection.

The finding says the device is busy. §11.3 forbids concluding anything about the health of the hardware from it: a device at 100% busy is usually a device doing its job.
