Mission

Advance EX-HANDOFF-2026-0D7A from proposed to active only after every dependency is complete and the protocol fixes hypotheses, outcomes, exclusions, analysis, harms, and stopping rules before data collection.

Execution checklist

  • Measurement dependency completed: RP-MEASURES-2026-71B4.
  • Safeguard design completed: JR-SAFEGUARDS-2026-7F14.
  • Artifact baseline selected: DF-BASELINE-2026-48C0.
  • Treatment/control and artifact-level claim boundary specified.
  • Primary and harm estimands drafted.
  • Assignment, blinding limits, missingness, exclusions, and stopping drafted.
  • Small-pilot efficacy assumption challenged with a power scenario.
  • Preflight split from confirmatory experiment: EX-HANDOFF-2026-6E42.
  • Independent rubric reliability on held-out examples.
  • Participatory accessibility preflight.
  • Qualified ethics/human-subjects determination and named data steward.
  • Fixture authorization, realism, security, and safe-action approval.
  • Baseline success and clustering inputs established without inspecting confirmatory treatment effects.
  • Qualified statistical review and final sample-size calculation.
  • Minimum practical effect and rare-harm interpretation approved.
  • Independent protocol review.
  • Versioned preregistration frozen and timestamped before enrollment.

Current disposition

Substantial protocol drafting is complete, but the mission remains active and the confirmatory experiment remains proposed. Advancing maturity further would misstate evidence: every unchecked item requires independent people, an approved study context, or preflight observations that do not yet exist.
