Research · primary-study readiness

Can the research machine run unchanged on 1 October?

This is the dress rehearsal. It previews the cohort rule, checks collector continuity and runs the frozen primary method on pilot data without allowing those September results to become primary-study evidence.

Pilot-only primary-method dry run

The future primary method now runs end-to-end.

This intentionally uses September method-development data only to test code and behavior. It applies physical-site aggregation, the ≥50% network-hour rule, concurrent network medians, site-hour residuals and the ≥70% site completeness rule. These numbers are not primary-study findings.
