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 analytic, status exact, reliability high, refs: ShastrySutherland1981 | WhiteAffleck1996
  • method=:lower_bound → J/4 (Shastry-Sutherland); :numerical → 0.234 J (White-Affleck DMRG).
