Differentiators

  • Captures the plan, searches, source evaluation, conflict resolution, and unresolved gaps as one end-to-end trajectory.

Record Schema

schema — 31 fields
action_maskarrayOptional mask identifying trainable or scoreable actions in the trajectory.

applicable_time_windowstringTime period within which the answer and evidence are applicable.
citation_dpoobjectCitation-level preference data and sentence attribution.
competencies_exercisedarrayResearch and reasoning competencies evaluated by the task.
conflictsobjectConflicting claims, resolution strategy, and unresolved conflicts.
contamination_checkobjectAssessment of whether the task can be answered without external search.
cross_document_requirementnumberScore indicating how strongly the task requires evidence across documents.
difficulty_calibrationobjectEstimated steps and baseline accuracy measures used to calibrate difficulty.
dpoobjectChosen and rejected trajectories with preference source and margin.

Methodology & Quality

Methodology

SME involvement

Domain-expert curated with up to L2 review

Stressors

Multi-hop search, conflicting sources, evidence synthesis, and unresolved uncertainty.

Design criteria

  1. Preserve complete multi-hop research traces rather than final answers alone.

Build assumptions

Quality approach

  • Legal sample trajectories include rubric-based rewards and retained comparison groups.

Known limitations

Customization & Scalability

Custom sets available. Additional volume in progress
