Genki Theory: A Dual-Universe Research Framework Built on KOKU Cosmology

This exploratory technical note defines Genki Theory as a dual-universe research framework built on KOKU cosmology. The visible universe consists of source-space domains containing ordinary matter, fields, clocks and instruments. A coincident hidden universe is hypothesized to arise from the connected interstices between those domains. KOKU cosmology supplies the observational-time sector, including KDT-1 as an unvalidated observational law rather than a local force law. The framework requires one total action, common causal structure, explicit inter-sector exchange, complete conservation laws, and recovery of established physics in tested limits. Apparent anomalous forces, if they survive ordinary error models, are treated as candidate momentum exchange between sectors, not as reactionless propulsion. No empirical evidence, proof, validation, peer review or physical detection of the hidden universe or Genki Theory is claimed.
