🟢 IsingSquare/SpontaneousMagnetization/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: Yang 1952
  • M(T) = (1 - sinh⁻⁴(2βJ))^(1/8) for T < T_c.

Test calls

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

verify(IsingSquare(; J = J), SpontaneousMagnetization(), Infinite(); route = :limiting_case, fetch_kw = (; β = 0.9βc), independent = 0.0, agree_within = 1.0e-10, refs = ["Yang 1952: m = 0 for T >= Tc"])
verify(IsingSquare(; J = J), SpontaneousMagnetization(), Infinite(); route = :second_closed_form, fetch_kw = (; β = β), independent = m_ind, agree_within = 1.0e-9, refs = ["Yang 1952: m = (1 - sinh^{-4}(2βJ))^{1/8}, exponent 1/8"])

Assurance (provisional)

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