Bounded Model-Reliability Audit

Determine whether your model evidence justifies the next expensive engineering action.

Current stateCOMMERCIAL DIAGNOSTIC ROUTE
Core Proposition

Bring the model result, the decision it informs and the consequence of being wrong. Systemica applies declared perturbations, comparison routes, negative controls and replay discipline to determine what remains stable, what becomes fragile and what evidence is still missing.

What Gets Stress-Tested

Five diagnostic dimensions evaluated under controlled local computation.

1. Model & Split Changes

Does the conclusion survive a different reasonable modelling route or cross-validation fold?

2. Noise & Measurement Disturbance

Does a small noise injection or sensor tolerance shift overturn the primary decision?

3. Missing Features & Input Sensitivity

Which conclusions depend disproportionately on a single fragile input descriptor?

4. Population & Distribution Shifts

Does the model result travel beyond the specific training/calibration population that produced it?

5. Broken Controls & Null Refusals

Can the audit logic correctly refuse random or uninformative structure that should not be trusted?

What the Customer Supplies & The Audit Workflow

Low-friction intake designed to run locally or under strict confidentiality.

What You Supply

  • Declared Decision: The engineering action under consideration (simulation, testing, procurement).
  • Consequence Boundary: The cost and risk of acting on an unstable conclusion.
  • Model & Data Inputs: Reproducible notebook, script, dataset, or exported model predictions.
  • Execution Constraints: Local execution requirements or confidential dataset boundaries.

Bounded Audit Workflow

  1. Intake & Contract
  2. Perturbation Run
  3. Weakness Register
  4. Replay Receipt
  5. Decision Packet
Every audit produces a deterministic replay receipt and an explicit decision rating.

Evidence Ceiling

Current Evidence Ceiling

The current GIL evidence includes locked shear and bulk repeats, controlled perturbations and negative controls, four model families and a 10,982-row Materials Project expansion. The work shows that some descriptors can remain predictive while being too unstable to support the same explanation across reasonable changes.

Evidence Ceiling: Current ceiling: internally replayed, bounded materials-model evidence. It is not yet independent-source, customer or production validation.
