Sal-Meter Open Competition — Phase 0 PI Invitation Dossier v1.1 (Scientific Validation Framework Edition)

Sal-Meter Phase 0 is a strict, reproducibility-first state-separability experiment. Single question:Can a biochemical interface signal be measured in a reproducible and independently verifiable manner under CAIS compliance constraints? This dossier is an invitation to Principal Investigators (PIs) and research teams to participate in a validation-driven framework (not product development, not marketing, not winner-takes-all). What you can do immediately: Choose at least one state module: Sleep / Meditation / Acute Stress / Clinical Anesthesia Collect signals under your own lab setup (hardware and algorithms remain your autonomy) Run leakage-protected cross-validated classification Report Balanced Accuracy (primary metric) and negative controls Submit a structured package for audit-ready archiving Phase 0 decision rule (fixed): Balanced Accuracy ≥ 0.65 with cross-validation and documented leakage protection Null results are acceptable if methodologically sound.This program is designed to minimize reputational risk for participating labs:predefined metrics, explicit negative controls, and canonical compliance boundaries.Independent replication across laboratories is encouraged, and cross-lab concordance will be transparently archived.
