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: uncorroborated-but-feasible

src claims this hub and dense ED is feasible, but no corroboration card exists. Actionable: add a route = :ed_finite_size or :second_closed_form card.

src claim

  • method jks_qtm_nlie, status approx, reliability medium, refs: JuttnerKlumperSuzuki1998
  • "eq (53) NLIE โ€“ the SIX-unknown real-axis form (two boundary values " * "each of b, c, cbar), transcribed from the arXiv LaTeX source. " * "Supersedes the eq (47) route this row used to call, which is retained " * "in Hubbard1Djksnlie.jl for comparison but is no longer reachable " * "from fetch. That route carried FOUR defects at once (#798): it " * "convolved the c channel with K1 where the paper says K1bar, used " * "log(1+b) where it says log(1+1/b), collapsed the +- boundary index " * "into the bar index so eq (51) needed six unknowns and it had four, " * "and โ€“ dominating the error โ€“ was fed mu = U/2 as though it were the " * "PAPER's half filling. CONVENTION, now executable rather than prose " * "(_jks_paper_mu / _jks_plain_offset in Hubbard1D.jl): the JKS " * "Coulomb term is symmetric, U(ndown-1/2)(nup-1/2), so ITS half " * "filling is mu = 0 and fpaper(mu) = fplain(mu+U/2) + U/4. The old " * "route passed mu straight through, i.e. solved a DOPED system and " * "compared it against half-filled ED. That mismatch was silent โ€“ " * "nothing errored, the numbers were merely wrong by the doping energy. " * "IMPROVEMENT, NOT CLOSURE: eq (53) reproduces the parameter-free " * "high-T limit f -> -log(4)/beta and returns a finite value for every " * "beta where the old route gave NaN, but see error_order for the " * "low-T drift that remains."

Corroboration

No corroboration card. Flagged by the R1 risk-linter (src claims this hub, ED is feasible, no independent card).

Assurance (provisional)

  • level: uncorroborated-but-feasible ๐ŸŸ 
  • cards: 0 ยท model ED-feasible
  • RES not wired โ€” measured residuals / confidence are not shown yet.
