Single-model fairness monitor (automated-decision disparity audit)
ONE classifier trained with a fairness-aware loss (demographic-parity / equalized-odds penalty) plus an external held-out audit cohort that measures protected-class disparity post-hoc. Non-infringing design-around of US11922435B2's dual-model bias architecture: no second/monitoring model, no pseudo-unbiased corpus, no dual-classifier comparison. Complements the HO-191 pay-equity analyzer (compensation disparity) on the protected-class fairness thread.

Maturity evidence
- Functioning
- train + audit implemented (core/fairness-monitor.ts); 8/8 tests pass (tests/fairness-monitor.test.ts): biased cohort flags disparity, fairness-loss training reduces measured disparity, degenerate single-group case, deterministic, structural boundary.
- Valuable
- Complements the HO-191 pay-equity analyzer on the protected-class fairness thread (decision-outcome disparity vs compensation disparity). No paying consumer yet; in-force design-around pending legal review before commercial use.
- Understood
- README section + mermaid (train-with-fairness-loss -> audit-cohort -> disparity-report) + machine-readable boundaryAttestation in every report.
- Integrated
- REST + MCP from one declaration (registered in wage-benchmark MCP register + registry.ts contracts). No downstream consumer wired yet.
