🟢 IsingChain1D/CorrelationLength/Infinite

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: corroborated-at-p

Independently corroborated. See the cards below.

src claim

  • method analytic, reliability high, refs: Ising 1925
  • ξ(β,h) = 1/log(λ+/λ-); at h=0 reduces to 1/log(coth βJ).

Test calls

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

verify(IsingChain1D(; J = J), CorrelationLength(), Infinite(); route = :second_closed_form, fetch_kw = (; beta = β), independent = 1 / log(coth(β * J)), agree_within = 1.0e-9, refs = ["Ising 1925: ξ = 1 / log(coth βJ) at h = 0"])
verify(IsingChain1D(; J = J), CorrelationLength(), Infinite(); route = :second_closed_form, independent = -1 / log(tanh(β * J)), agree_within = 1.0e-12, refs = ["Kramers-Wannier 1941: ξ(β) = -1/log(tanh(βJ)) per lattice spacing"], fetch_kw = (; beta = β))

Assurance (provisional)

  • level: corroborated-at-p 🟢
  • cards: 2 · model ED-feasible
  • RES not wired — measured residuals / confidence are not shown yet.
