Project Status

Release status

• Current release: v0.2.0 (research preview, alpha quality).
• API may evolve as estimator coverage and diagnostics expand.

Versioning and deprecations

• We follow SemVer; breaking changes are expected in 0.x, with tighter stability after 1.0.
• Deprecated public APIs warn for at least one minor release before removal.

Current scope

• Unconfounded OPE with explicit estimands, diagnostics, and synthetic benchmarks
• Bandit and sequential propensity sensitivity analysis under bounded confounding
• Baseline and advanced estimators for IS, WIS, PDIS, DR, WDR, MAGIC, MRDR, FQE
• Estimator selection heuristics and behavior policy estimation

Experimental and non-goals

• Confounded and transport settings are exposed as experimental interfaces only
• Representation learning claims are treated as heuristics unless identified

Roadmap

• Transport and mechanism shift tooling
• Expanded confounded MDP benchmarks and sensitivity analyses
• Additional diagnostics for model misspecification
