TopologicalInvariant — quantity index
Generated by docs/atlas/generate.jl — a pure VIEW over the *_registry.jl claims + the static test/INVENTORY.jsonl AST scan. No test is executed and no src is run; test/INVENTORY.jsonl is regenerated in-place (idempotently) from that static scan; fetch/@register untouched. Assurance labels are PROVISIONAL: residuals / confidence are not shown yet (RES not wired). Badges reflect the committed test AST, not the latest CI run — a hub can read green while its @test is red between regenerations. @sweep = a graceful regime-resolution gap, not card omission.
All (Model, BC) hubs src claims for the TopologicalInvariant observable. Empty cells = this model doesn't yet have a TopologicalInvariant registered at that BC — i.e. where this quantity could be added to other models.
Definition
Topological Z_2 invariant of a 1D BdG superconductor (Kitaev 2001). Defined as the Pfaffian sign at the time-reversal-invariant momenta k = 0 and k = π,
(extracted from src/core/quantities.jl docstring.)
