Proposed sheaf-theoretic model of aging as cross-hallmark repair obstruction
The abstract proposes a mathematical model in which aging is a cost-constrained, stochastic loss of repair closure, with cross-hallmark obstruction rank reducing coupled repair reserve. Published clock, muscle-regeneration and senolytic results are mapped to the model, not used as empirical validation. [1]

Proposed model of repair closure loss
The abstract states that the twelve hallmarks of aging describe heterogeneous changes but do not by themselves explain organism-level loss of repair capacity. It proposes representing aging as a cost-constrained, stochastic loss of autopoietic repair closure, organizing hallmark processes as coupled local-to-global constraint layers on a finite biological complex. Global sections represent compatible repair modes; a connecting morphism measures when coherent regulatory states generate material-repair incompatibilities.

Accounting identity and dynamical extension
The principal accounting identity states that coupled repair reserve equals material-repair closure plus regulatory-interface closure minus cross-hallmark obstruction rank. The abstract says the identity follows from standard exact-sequence and rank-nullity arguments, while its biological content lies in constructing the coupled aging object and interpreting obstruction rank as cross-hallmark repair incompatibility. A dynamical extension places repair under finite, fallible control, stochastic perturbation, delayed feedforward dependence and an explicit viability domain; additional surveillance can reduce global repair when coupling costs exceed local gains.

Two-compartment example and literature-anchored mappings
The abstract describes a reproducible two-compartment example specifying stalk variables, restriction maps, coboundary matrices, connecting-map rank and an approximate persistence interval. It states that published epigenetic-clock, skeletal-muscle regeneration and senolytic results are literature-anchored mappings rather than empirical validation. The proposed invariants therefore target one structural dimension of aging: loss of achievable, globally compatible repair under finite biological control.
