🟢 LongRangeXY1D/MassGap/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, status exact, reliability high, refs: LiebSchultzMattis1961 | Pfeuty1970 | MaghrebiGongGorshkov2017
  • α=Inf NN XX limit: Δ = 2·max(0, |h|-2J); finite α deferred to Phase 2.

Test calls

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

verify(LongRangeXY1D(; 0.0 = 0.0), MassGap(), Infinite(); route = :second_closed_form, independent = 0.0, agree_within = 1.0e-10, refs = ["NN XX chain: gapless for |h| <= 2J (free fermion)"])
verify(LongRangeXY1D(; 1.0 = 1.0), MassGap(), Infinite(); route = :second_closed_form, independent = 0.0, agree_within = 1.0e-10, refs = ["NN XX chain: gapless for |h| <= 2J (free fermion)"])
verify(LongRangeXY1D(; 2.0 = 2.0), MassGap(), Infinite(); route = :second_closed_form, independent = 0.0, agree_within = 1.0e-10, refs = ["NN XX chain: gapless for |h| <= 2J (free fermion)"])

Assurance (provisional)

  • level: corroborated-at-p 🟢
  • cards: 3 · model ED-feasible
  • RES not wired — measured residuals / confidence are not shown yet.
