Original ledger classification: edge existence forced by the invertible bulk (anomaly inflow) -- realised non-gappable chiral edge on the lattice strip [E]/[C]/[O]

Original claim text

Track 1 (2026-06-23): the bulk-edge / anomaly-inflow leg (S4 of the v356 chain) made CONCRETE on the v367 lattice model -- a finite STRIP of the gapped p+ip model has a REALISED, non-gappable chiral edge, so edge EXISTENCE is a CONSEQUENCE of the bulk being a nontrivial invertible phase (anomaly inflow), NOT a separate assumption. This directly discharges the v336/v351 'does the gapped collar HAVE a chiral edge?' residual on the lattice. [E] TOPO IN-GAP EDGE STATES: for M=1 (|C|=1) the strip spectrum reaches min_kx|E|~0 deep in the bulk gap (a chiral edge branch traverses the gap). [E] TRIVIAL CLEAN GAP (neg control): for M=3 (C=0) min_kx|E|>0.3 stays well above zero. [E] EDGE-LOCALISED: the near-zero in-gap state's weight is concentrated within 4 sites of a boundary (edge>>bulk). [E] BULK-EDGE CORRESPONDENCE: the chiral edge branch count = bulk Chern |C|=1 (one chiral Majorana per edge) => the 16-copy carrier has a 16-Majorana chiral edge, c_-=8. [C] ANOMALY INFLOW: a gapped invertible phase with c_-!=0 cannot have a gappable edge, so the chiral edge of the collar (c_-=8, v301/v356) EXISTS as a consequence of the bulk. [O] residual: the continuum scaling-limit of that lattice edge (MMST v336) stays open; v368 establishes edge EXISTENCE on the lattice, not the scaling limit.

Original classification detail

[E] the strip edge spectrum + localisation + bulk-edge correspondence + the trivial neg control; [C] the anomaly-inflow edge-existence argument; [O] the continuum scaling limit. Discharges the S4 'edge exists' leg on the lattice; does NOT close SEAM.EQUIV.01.

Location recorded in the ledger

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.

    Track 1: the bulk-edge / anomaly-inflow leg (S4 of the v356 chain) made CONCRETE on the v367 lattice model -- a finite STRIP of the gapped p+ip model has a realised, non-gappable chiral edge, so edge EXISTENCE follows from the invertible bulk (anomaly inflow), NOT a separate assumption. [E] topo in-gap edge states (M=1 strip min_kx|E|~0) vs trivial clean gap (M=3, neg control); [E] the near-zero state is edge-localised (weight within 4 sites of a boundary, edge>>bulk); [E] bulk-edge correspondence (edge branch count = bulk Chern |C|=1) => 16-Majorana edge, c_-=8. [C] anomaly inflow: a c_-!=0 invertible bulk cannot have a gappable edge => discharges the v336/v351 'does the edge exist?' residual on the lattice. [O] residual: the continuum scaling limit (MMST v336). Establishes edge EXISTENCE on the lattice; does NOT close SEAM.EQUIV.01.
