Burst cadence is the elevated, incident-triggered data-reporting interval a sensing node adopts in place of its normal baseline cadence, for a bounded duration, when a hazard is recognised.
The hazard classes worth detecting have precursor windows spanning five orders of magnitude - seconds for an open flame, weeks for a failing bearing. Any single fixed sampling rate is therefore either too slow for the fast events or wastefully fast for the slow ones.
The node reports one vector every ten seconds at baseline and one per second in burst, for up to five minutes, returning automatically under platform control.
A node sampling slowly enough to be stored indefinitely escalates sixty-fold for the five minutes that actually matter, then returns without anyone switching it back.
