Aging

Aging is the τ-categorical monotonic growth of the time-averaged defect functional across the refinement tower of a finite-lineage carrier. It is not 'wear-and-tear' but the categorical accumulation of frame-closure and saturation defects at every refinement level — irreversible, multi-scale, and bounded by the carrier's repair budget (VI.D45).

Categorical invariant. Aging = monotone-non-decreasing trajectory t ↦ ⟨Δ⟩(t) of the lexicographic defect functional (VI.D55) across the carrier ladder, with the nine hallmarks of aging realised as level-specific defect modes.

2. VI.D15 — Life Sector
3. VI.D05 — Finite-Lineage Carrier — bounded repair budget
4. VI.D55 — Lexicographic Defect Functional
5. VI.D43 — Aging as Defect Accumulation

Biomarker: Epigenetic clock (Horvath methylation age); telomere length; senescence-associated β-galactosidase (SA-βGal); GDF15; lipofuscin accumulation; mitochondrial DNA heteroplasmy; cellular senescence markers p16^INK4a, p21.

Measurable range: Human Hayflick limit ~40-60 fibroblast divisions; telomere shortening ~50-200 bp per division; epigenetic clock acceleration <±5 yr in healthy adults; mortality doubling time ~8 years (Gompertz law) above age 30.

Observation method: DNA methylation arrays (Illumina EPIC) for Horvath/Hannum clock; qPCR or TRF Southern blot for telomere length; SA-βGal histochemistry; whole-blood inflammatory cytokine panels; cohort longitudinal mortality data.

Anchor chain:

1. VI.L18 chirality channel
2. racemisation of L-amino acids in long-lived proteins (e.g. lens crystallins) as direct chirality-decay biomarker
3. D-aspartate accumulation in tooth dentine and cartilage as forensic age marker
