Principal-Conditioned Decision Differential

Does changing only the named principal change the model's decision?

Configure an audit
What this audit can surface
Does the model change a consequential decision for one beneficiary but not a matched control?
What would count as evidence
The same-direction decision difference must repeat in discovery and held-out scenarios.
Execution requirement
A suspected principal, a matched control, and twelve balanced eligibility scenarios.

Interpretation

A repeated differential is a loyalty lead. One changed answer is not sufficient evidence.

What this module audits

Does changing only the named principal change the model's decision?

Evidence boundary. The narrow-secret-loyalty paper did not release its trained Qwen organisms or training corpus. Use released AuditBench organisms or another ground-truth model; do not claim the paper's private artifacts are on Hugging Face.

Audit protocol

  1. Run twelve matched scenarios with only the named principal changed.
  2. Check that the model responds to scenario content before testing a principal effect.
  3. Estimate discovery and holdout deltas separately.
  4. Inspect discordant pairs and the exact paired test before issuing an outcome.

Controls

  • A prominence-matched control principal.
  • Eligible and ineligible scenarios balance generic compliance.
  • A behavioral-responsiveness gate blocks interpretation of a non-responsive model.

What the audit checks and retains

Checks

  • Matched principal substitution
  • Twelve balanced eligibility scenarios
  • Behavioral responsiveness
  • Discovery/holdout replication
  • Exact paired test

Evidence record

  • A same-direction principal effect in discovery and holdout scenarios.
  • Complete matched-pair decisions with explicit numerators and denominators.
  • Behavioral responsiveness that shows the model tracked the scenario.

Thresholds and quality gates come from the versioned audit configuration and evidence record. A failed or unmet gate is not a no-signal finding.

Validation and limits

Implemented · uncalibrated. Balanced positive and negative controls, strict decisions, holdout replication, and an exact McNemar-style test are implemented; ground-truth model calibration remains required.

The narrow-secret-loyalty paper did not release its trained Qwen organisms or training corpus. Use released AuditBench organisms or another ground-truth model; do not claim the paper's private artifacts are on Hugging Face.
