Life Sector

The Life Sector is the τ-categorical sub-category that hosts all biological structure, process, and information. It is one of the canonical τ-sectors at the E₂ enrichment level, characterized by its closed Life Loop Class and the kinetic pseudoscalar amplification of weak-sector chirality.

Categorical invariant. τ-categorical sector at E₂ where the Life Loop Class (VI.T09) is non-trivially realized; the conceptual home of cells, organisms, ecosystems.

Primary registry anchor: VI.D15

Supporting items: VI.D04, VI.T09, VI.D31, VI.L18

1. I.K0 — Universe Postulate
2. VI.D04 — τ-Distinction defines structural separability across sectors
3. VI.D15 — Life Sector — the τ-sector hosting biological structure

Biomarker: All living organisms — domain-classified across Bacteria / Archaea / Eukarya (three-domain taxonomy, VI.D35); biosignatures include cellular structure, homochirality, metabolic activity, hereditary continuity.

Measurable range: Earth's biosphere: ~10³⁰ cells total; mass ~5.5 × 10¹¹ tonnes (carbon-equivalent); diversity ~10⁷-10⁹ species (estimated); span of habitats: from -89°C (Antarctic) to 122°C (deep-sea hydrothermal vents).

Observation method: Microscopy across scales; metabolomics; ³H/¹⁴C-labeled isotope assays for metabolism; genomics; ribotyping for taxonomy.

Calibration anchor: LG-Y02-kinetic-pseudoscalar-channel

Anchor chain:

1. VI.L18 kinetic pseudoscalar channel — anchors all life-sector biomolecules
2. homochirality propagates through every life-sector morphism
3. the K_χ channel's parity-odd time-even signature defines the boundary of the life sector
