Definition

Full descent diagram

For a cover of a space or spacetime , the full descent diagram records local fields on patches, their identifications on overlaps, and every required higher compatibility. A higher stack satisfies descent when

Definition

Reconstruction fiber

The space of full reconstructions compatible with specified admitted data. Its emptiness, components, and higher homotopy describe obstruction, ambiguity, and invisible automorphisms.

Definition

Truncated limit-initiality

For an -truncated target, the witness functor is -limit-initial when the relevant comma spaces are -connective. This is a standard, diagram-independent sufficient condition ensuring that restriction preserves the required limits.

Dirichlet Passage Pencil

The Dirichlet passage pencil is the finite positive matrix problem that measures the least ordinary-gluing energy carried by a selected charged passage after every allowed interior relaxation and every common Dirichlet zero mode have been removed.

Definition

Seam Reserve

The seam reserve is the positive fraction of the local Dirichlet passage cost that remains after partition, boundary-comparison, and catalog-representative errors are subtracted.

Definition

Coherent Selected Branch

A coherent selected branch is a compatible family of physical choices—carriers, source and fusion sectors, comparison maps, associators, form domains, complete-ground lineage, and Hamiltonian-descent controls—on which the later analytic statements are actually defined.

Certified Raw Arrow

A certified raw arrow is a raw refinement whose observable and carrier maps satisfy GLC, whose carrier preserves the distinguished vector, and whose carrier is Dirichlet-covariant.

Dirichlet Carrier Category

is the category whose objects are Hilbert carriers with a distinguished fixed vector and specified Dirichlet semigroup, and whose morphisms are bounded maps preserving that vector and intertwining the semigroups.

Admissible Transport

Admissible transport first meant scale-comparison transport encoded by a 2-lax natural transformation; later GAT formulations organize more general certified physical comparisons.

Descent defect

The defect records outputs that remain when the chosen realization makes the inputs disappear. If defines an operator on , Proposition 7.2 identifies this defect with the multivalued part of its graph closure.

Mixed incidence

It measures what the new source increment adds to a given reconstruction component. This is an algebraic quotient, before analytic closure.
