Provisional v2 view — RES not wired

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.

Assurance level: cited-only

Backed only by a literature citation — no in-repo independent re-derivation yet.

src claim

  • method dmrg_reference, status exact, reliability medium, refs: WhiteAffleck1996 | Eggert1996
  • Δ ≈ 0.234 J DMRG; Shastry-Sutherland 1981 bound Δ ≥ J/4 is trimer-sector only.

Test calls

The exact verify(...) call the harness executed for this hub (reconstructed from the test AST):

verify(MajumdarGhosh(; 0.5 = 0.5), SpinGap(), Infinite(); route = :literature_value, independent = 0.234 * 0.5, agree_within = 1.0e-14, refs = ["White-Affleck 1996 DMRG; Eggert 1996: spin gap Δ ≈ 0.234 J"])
verify(MajumdarGhosh(; 1.0 = 1.0), SpinGap(), Infinite(); route = :literature_value, independent = 0.234 * 1.0, agree_within = 1.0e-14, refs = ["White-Affleck 1996 DMRG; Eggert 1996: spin gap Δ ≈ 0.234 J"])
verify(MajumdarGhosh(; 3.0 = 3.0), SpinGap(), Infinite(); route = :literature_value, independent = 0.234 * 3.0, agree_within = 1.0e-14, refs = ["White-Affleck 1996 DMRG; Eggert 1996: spin gap Δ ≈ 0.234 J"])
verify(MajumdarGhosh(; 1.0 = 1.0), SpinGap(), Infinite(); route = :literature_value, independent = 0.234 * 1.0, agree_within = 0.005, refs = ["White-Affleck 1996 PRB 54 9862: MG point singlet-triplet spin gap Δ_S ≈ 0.234 J (DMRG)"])

Assurance (provisional)

  • level: cited-only ⚪
  • cards: 4 · model ED-feasible
  • RES not wired — measured residuals / confidence are not shown yet.
