Original ledger classification: one-particle rigidity + scaling limit [E]/[C]: via Araki self-dual CAR (state<->symbol P, cited) the gapped ground state is the UNIQUE quasi-free realisation (P^2=P), its kernel is Cauchy (~1/N, limit exists), and the limit is the c=1 Dirac CFT (EE c-fit ~1 => c_-=16*1/2=8); Shale-Stinespring makes the Bogoliubov map implementable, upgrading R1 from a bald axiom to an audited [C]; with v463 the residual is entirely certification, zero open internal mechanism; SEAM.EQUIV.01 stays [O]

Original claim text

The one-particle RIGIDITY + scaling limit attacking R1 (2026-06-30, A of the A+B round) -- the REALISATION input of SEAM.EQUIV.01. The seam is quasi-free (v113/v160/v161), so by Araki self-dual CAR the whole net is the second quantisation of its one-particle symbol P, and R1 collapses to a finite-per-mode statement about P. [C] ARAKI SELF-DUAL CAR: a gauge-invariant quasi-free state <-> its symbol P (0<=P<=1) bijectively (Araki 1971; Shale-Stinespring 1965), so a realisation is fully determined by P. [E] RIGIDITY: the gapped ground state is the UNIQUE quasi-free state with P=projection onto K<0 (P^2=P, hermitian to <1e-12), K fixed by gap+chirality+reflection (v426) -- no second realisation. [E] ONE-PARTICLE SCALING LIMIT EXISTS: the real-space kernel is Cauchy on a fixed window (max|P_2N-P_N|~1/N -> 0), so P_inf exists (Gaussianity is why a computation reaches it). [E] LIMIT IS c=1 DIRAC (c_-=8): entanglement S(L)=(c/3)ln L gives c -> 1 (per Majorana 1/2; Peschel/Calabrese-Cardy, ties v450), 16 copies -> c_-=8. [C] Shale-Stinespring: gauge-invariant => no pairing block => the Bogoliubov map is implementable, GNS reps quasi-equivalent. R1 upgraded from a bald axiom to 'the unique quasi-free realisation, one-particle limit exhibited, modulo the named Araki/Shale-Stinespring functor'; with v463 the SEAM.EQUIV.01 residual is now entirely certification, zero open internal mechanism -- closed modulo cited theorems. SEAM.EQUIV.01 stays [O].

These document locations are recorded directly on the ledger row. They are document level navigation, rather than a newly inferred section citation.

Sections that explicitly cite this claim

A literal claim identifier is present in these paper sections. The section and its premises determine what the citation supports.

Navigation through a shared verification script

These sections cite a script associated with the claim. This is a source navigation join, rather than an explicit citation of the claim or a theorem equivalence.

    SEAM.EQUIV.ONEPARTICLE.01: the one-particle RIGIDITY + scaling limit attacking R1, the REALISATION input of SEAM.EQUIV.01 (A of the A+B round). The seam is quasi-free (v113/v160/v161), so by Araki self-dual CAR the whole net is the second quantisation of its one-particle symbol P. [C] ARAKI: state <-> symbol P bijectively. [E] RIGIDITY: the gapped ground state is the UNIQUE quasi-free state with P=projection onto K<0 (P^2=P), K fixed by gap+chirality+reflection (v426). [E] ONE-PARTICLE SCALING LIMIT EXISTS: kernel Cauchy on a fixed window (~1/N). [E] LIMIT IS c=1 DIRAC: entanglement S=(c/3)ln L gives c->1, 16 copies -> c_-=8 (ties v450). [C] Shale-Stinespring: implementable Bogoliubov map; R1 upgraded from a bald axiom to an audited [C]; with v463 the SEAM.EQUIV.01 residual is entirely certification, zero open internal mechanism. SEAM.EQUIV.01 stays [O]. Python-only (numpy).
