Gerostasis

Gerostasis, in the covolution framework, is the maintained regime of aging-resistant regulatory order: the condition in which a horon preserves its identity, feedback fidelity, perturbation-recovery capacity, and required (requisite) functional variety in its cybernetic attractors and switching architecture, despite molecular noise and symvironmental perturbation. Gerostasis is a regime/state — the youthful or functional attractor architecture that interventions aim to preserve or restore — not a degradation process.

The term combines gero- (Greek geras, old age) with -stasis ("standstill, steady-state"), paralleling homeostasis. Its antonym is Gerorhesis, the aging-directed degradative flow that erodes the gerostatic regime; the measurable expression of that flow is Geroflux and its direction is Gerotropy. (An earlier version of this page used "gerostasis" for the degradation process; that material now lives at Gerorhesis.)

stable cell identity preserved lineage markers
feedback fidelity recovery after perturbation
low non-required variety few off-lineage / hybrid states
attractor depth strong return to baseline
symvironmental fit appropriate ligand–response mapping

Relation to capacity C

In terms of functional-information-processing capacity C = (A, M, P, K), gerostasis is maintenance of the viability-weighted ‖C‖ against perturbation (Δ‖C‖ ≈ 0). Covolution raises ‖C‖; Gerorhesis degrades it; gerostasis holds it.
