SacrificialProbe

Learning via cheap, instructive failure

Definition

Mechanism

A Generalized Pattern where an Agent sends a low-cost 'probe' into a System expecting it to fail, but designs the failure to be instructive. 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.

Preconditions

  1. System failure Modes are observable

Postconditions

  1. Strategy updated

Invariants

  1. Cost Asymmetry: Cost(Probe) << Cost(MainPayload)
  2. Instructive Failure: InfoGain(Failure) > EntropyReductionThreshold
  3. Strategy Update: MainPayload parameters are a function of ProbeResult

Risks

Failure modes

  1. Probe too expensive

    breaks the Cost Asymmetry invariant, making the sacrifice unaffordable.

  2. Silent probe failure

    Probe fails but produces no observable signal, destroying the Instructive Failure property.
