+Clarus Population Framework Transition Integrity v0.1
+
+What this dataset tests
+
+- You track how the study population is defined as it moves across formal frameworks
+- You detect when inclusion, exclusion, or analysis sets change without explicit mapping
+- You flag population drift introduced between planning and reporting stages
+
+Framework transitions covered
+
+- Trial registry → protocol
+- Protocol → statistical analysis plan
+- SAP → publication
+
+Scope
+
+- One trial
+- Multiple population definitions
+- Multiple formal frameworks
+
+Typical failure modes
+
+- Registry eligibility differs from published cohort
+- ITT redefined as modified ITT without mapping
+- Post-randomization exclusions introduced
+- Per-protocol sets promoted without justification
+- Subgroup restrictions applied retroactively
+
+What this dataset does not test
+
+- Internal narrative rhetoric within a single section
+- Endpoint definition changes
+- Safety or adjudication rule drift
+
+Task format
+
+- Each row presents a population definition in a source framework and a target framework
+- The model judges whether correspondence is valid
+- The model must name the mechanism of drift when correspondence fails
+
+Label meaning
+
+- A indicates invalid or unsupported population correspondence
+- B indicates valid correspondence with sufficient justification
+
+Use cases
+
+- Automated audit of trial registries versus publications
+- Systematic review population vetting
+- Regulatory submission consistency checks
+
+Version note
+
+- v0.1 establishes baseline population transition auditing
+- Higher-resolution variants may add explicit mapping requirements
