Fairshift Lab v1.1.0 — Policy Studio
Fairshift Policy Studio makes decision assumptions explicit.
Highlights:
- 20-seed, 72-cell benchmark across three distribution shifts, three error-cost declarations, and eight policy families
- Accessible fairness–utility Pareto explorer with uncertainty ranges and a complete data table
- Deterministic scenario JSON export with provenance and limitations
- Preregistered protocol and report plus a frozen, byte-reproducible result registry
- 100% Python statement and branch coverage; all web, accessibility, dependency, and code-scanning checks pass
Scientific boundary: synthetic, descriptive, internally verified evidence. This release is not externally peer reviewed, a policy recommendation, legal advice, fairness certification, or deployment approval.
