Provisional v2 view โ€” RES not wired

Generated by docs/atlas/generate.jl โ€” 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 โ€” 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, status exact, reliability medium, refs: Pauling1935
  • Pauling 1935 mean-tetrahedron closed form S/N = (1/2) log(3/2); a few percent below Nagle 1966.

Test calls

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

verify(SpinIce(), ResidualEntropy(), Infinite(); route = :second_closed_form, independent = 0.5 * log(3 / 2), agree_within = 1.0e-9, refs = ["Pauling 1935: ice-rule residual entropy S = (1/2) log(3/2) โ‰ˆ 0.2027"])
verify(SpinIce(), ResidualEntropy(), Infinite(); route = :second_closed_form, independent = log(3 / 2) / 2, agree_within = 1.0e-12, refs = ["Pauling 1935: spin-ice T=0 residual entropy = (1/2) log(3/2) per spin"])

Assurance (provisional)

  • level: corroborated-at-p ๐ŸŸข
  • cards: 2 ยท model ED-feasible
  • RES not wired โ€” measured residuals / confidence are not shown yet.
