• Causal Inference Under Partial Identification — Sensitivity and Evidence Hierarchies When real-world data fail strong ignorability, point identification gives way to bounds, proxies, and sensitivity analysis — an honest hierarchy of evidence that connects credible causal claims to semiparametric efficiency.
• OPE Deployment-Gate Playbook — Ruling "Trust / Distrust / A/B" Without Ground Truth Operating rules for an OPE deployment gate that rules on deployment from recommendation logs alone, under the real-world condition that nobody knows the true value V(π_e) — a 3-way gate over three diagnostics, the validity battery (a necessary-condition screen), the Λ-sensitivity certificate, the comparative-first principle, and the in-principle limit called observational equivalence. A playbook curation of the ope-to-decision benchmark.
