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

Pilot period — confirmatory interpretation is not allowed yet.

Phase: pilot. Registration: Prepared · not submitted. Frozen baseline: 0 sites. Candidate preview today: 71 sites.

PROTOCOL_LOCK

pass

Frozen protocol

Protocol DAH-PM25-2026-27-v1-1-1 is finalized with SHA-256 22076bd8e22dba94f8f6ca11bb66f0ac09fe4e9dc6801a1a6ebd76682835672a.

EXTERNAL_REGISTRATION

due

Prospective external registration

OSF registration must be submitted and timestamped before the primary period begins.

BASELINE_COHORT

scheduled

Frozen baseline physical-site cohort

The baseline cohort is intentionally not frozen yet; it is generated from the prespecified seven-day run-in at primary start.

PILOT_EXCLUSION

pass

Pilot-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

info

Immutable 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.
