The ETU Hybrid Standard v1.0 (EXPERIMENTAL / PROVISIONAL) defines a reproducible framework for quantifying transformation across physical, biological, and computational systems. It introduces the Elementary Transition Update (ETU) as a dimensionless unit of change, grounded in the six-substrate structure STEMIO (Space, Time, Energy, Matter, Information, Organization). Building on the Grammar of Existence — Architecture of Change, this standard provides a three-tier operational grammar: X – a dimensionless counter of discrete updates. ETU₀ – a reproducible reference closure, defined as one complete cycle of a minimal 3-node feedback loop returning to its initial state within ε = 5 %. wₓ – empirical weights for the six substrates, derived through Adaptive Weight Extraction (AWE). By defining ETU₀ as a conventional anchor—analogous to the historical kilogram or second—the standard resolves the proportionality problem between subjective measurement and objective reproducibility. It is intended as a provisional operational metric pending validation through multi-lab and multi-domain replication.
