TTbar — model index
Universal irrelevant TT̄ deformation of a 2-D QFT whose UV completion is a CFT of central charge c > 0, with deformation coupling λ of dimension (length)². Default c = 1 (free boson seed), λ = 0 (undeformed CFT). Any real λ is admissible: λ > 0 is the Hagedorn-like branch, λ < 0 is the "good-sign" branch.
c(λ) = c.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 (Quantity, BC) hubs src claims for TTbar. Cells link to the per-hub card; — = not yet implemented at that BC. The shape of the matrix is the gap visualisation: empty cells are where physics could be added next.
