Research integrity · live gate
Can this archive be interpreted as the prospective primary study yet?
This page turns the preregistration, protocol hash, study dates and baseline-cohort freeze into explicit machine-readable checks. It is deliberately stricter than the public exploratory tools.
Primary-analysis gate
Primary interpretation is blocked.
Phase: primary. Registration: Registered under embargo. Frozen baseline: 73 sites. Candidate preview today: 0 sites.
EXTERNAL_REGISTRATION
blockedProspective external registration
No verifiable pre-primary external-registration timestamp is attached; confirmatory interpretation is blocked until this is resolved and documented.
BASELINE_COHORT
passFrozen baseline physical-site cohort
73 eligible physical sites were frozen at 2026-09-30T19:00:00.082Z.
PILOT_EXCLUSION
passPilot-period exclusion boundary
Primary analysis must filter observations to timestamps on or after 2026-09-30T18:30:00.000Z; September pilot observations remain method-development data.
FROZEN_RESULTS_OBJECT
infoImmutable reporting object
Formal results must be generated from a named frozen release/export with code version, analysis-spec version and checksums; live pages are not citable primary results.
