Proof of Work

Evidence, not assertions.

This evidence hub documents what is demonstrated, what is reproducible, what is corroborated, and what still requires independent validation.

Evidence status

Strongest current proof

  • Reproducible: 50,000-observation synthetic credit-risk analysis.
  • Reproducible: PD test AUC ≈ 0.701 under the documented pipeline.
  • Verified: dynamic-programming FICO bucketing implementation.
  • Verified: public source code and correctness tests for the core risk algorithm.

Evidence still required

  • External validation: public/independent data.
  • Business impact: attributable outcome metrics.
  • AI evaluation: human-judged/public benchmark.
  • Automation: public/licensed corpus and timing study.
