Life Glossary — 78 entries, 7 categories
Glossary for the τ-framework's life domain — 78 canonical entries grouped by category.
The 78-entry life glossary covers biological structure, process, information, energy, temporal, systemic, and phenomenal categories. Every entry carries an empirical correlate (biomarker + measurable range + observation method), with kinetic-pseudoscalar (LG-Y02, VI.L18) as the kχ channel anchor for chirality-sensitive correlates.
Glossary contract. Every entry below carries a 4-section structure: τ-definition (categorical invariant + primary registry anchor), τ-derivation (chain of registry steps), domain-specific Section 3, and Lean coverage. The structure is uniform across all three domains so cross-references resolve unambiguously.
