Ghost Trial

A simulated production run in which representative data is passed through live business logic in parallel with real operations — the mechanism by which Continuous Regression Loops detect Logic Decay before it reaches the revenue loop.

Extended Definition​

A Ghost Trial is a shadow execution: the same logic gates, the same agent workflows, the same integration layers that handle real transactions — but fed with representative simulated data rather than live customer data. The Ghost Trial produces outputs that can be compared against expected parameters. When those outputs deviate, the deviation is logged and surfaced for architectural review. When they remain within expected ranges, the trial confirms that the live logic is still calibrated for the current data environment.

  • Continuous Regression Loop — The Ghost Trial is the mechanism that the Continuous Regression Loop runs: simulated data through live logic in parallel with real operations, producing outputs comparable to expected parameters.
  • Logic Decay — The Ghost Trial is the primary detection tool for Logic Decay: when the simulated outputs deviate from expected parameters, the decay is identified before any real transaction is affected.
  • Execution Divergence — Ghost Trial output deviations are expressed as Execution Divergence: the measured difference between expected parameters and actual outputs under the current data environment.
  • Deterministic Failure — When a Ghost Trial flags a deviation, the result is a Deterministic Failure event in the test environment: logged, escalated, and resolved before the corrected logic is deployed to the live system.
