The probe must be cheap relative to the main payload, and the failure {{mode}} must update the {{strategy}} for the main payload. Common in startups (landing pages), immunology (dendritic cells), and warfare (reconnaissance). It wraps the concept of a staked probe in a higher-order strategy where the probe's destruction is the intended {{signal}}.",
