Continuous Regression Loop

Arco's architectural practice of running Ghost Trials — simulated production data through live business logic — in parallel with real operations, to detect Logic Decay before it affects the revenue loop.

Extended Definition​

A Continuous Regression Loop is not a scheduled test or a deployment gate. It runs continuously, in parallel with live operations, feeding simulated production data through the same logic gates that handle real transactions. When the outputs of the Ghost Trial diverge from expected parameters, the loop flags the deviation before any real transaction has been affected. The logic is reviewed, recalibrated, and updated. The live system continues operating on the current logic until the recalibration is validated and deployed.

  • Logic Decay — The Continuous Regression Loop exists specifically to detect Logic Decay before it reaches the revenue loop: simulated data reveals miscalibration before real transactions are affected.
  • Execution Divergence — When Ghost Trial outputs deviate beyond the expected parameter range, the deviation measurement is expressed as Execution Divergence and triggers architectural review.
  • Architectural Certainty — Continuous Regression Loops are a required component of Architectural Certainty: a system without them cannot detect Logic Decay before it produces a visible revenue failure.
  • Deterministic Failure — The Continuous Regression Loop converts Logic Decay from a silent, accumulating failure into a Deterministic Failure: flagged, logged, and recoverable before it reaches production.
  • Ghost Trial — The Ghost Trial is the mechanism the Continuous Regression Loop runs: simulated production data through live logic, in parallel with real operations.
