"""v297 -- SEAM.EQUIV.A.LIT.01: Route A's 'one standard import' written out as a precise, CITABLE theorem stack. It does NOT prove the import; it types each literature theorem (statement + reference + input + output), verifies the three compose into the Route-A chain, and isolates the SINGLE open hypothesis -- showing the import is not a black box but a composition of established results conditional on exactly one geometric input. Route A's missing link (v287 L3): 'invertible (SRE) Gaussian bulk => single-sector (holomorphic) boundary => (E8)_1'. Decomposed into three citable theorems: LIT-A [established] invertible/SRE gapped phase => trivial bulk topological order (no nontrivial bulk anyons; trivial Drinfeld center). Refs: Kitaev, Ann. Phys. 321 (2006); Freed-Hopkins, Geom. Topol. 25 (2021). in: invertible (SRE) gapped bulk out: trivial bulk MTC (center) LIT-B [established] the bulk modular category is the Drinfeld center Z(C) of the boundary fusion category; a trivial center forces the boundary chiral net to be completely rational with trivial representation category (= holomorphic). Refs: Mueger, J. Pure Appl. Algebra 180 (2003); Kawahigashi-Longo-Mueger, Comm. Math. Phys. 219 (2001). in: trivial bulk MTC (center) out: holomorphic boundary net LIT-C [established] a holomorphic chiral net / VOA of central charge 8 is (E8)_1 -- the rank-8 even unimodular lattice is unique (E8), and the holomorphic c=8 net is its lattice net. Refs: lattice uniqueness (Conway-Sloane); Dong-Xu / Kawahigashi-Longo (holomorphic net = lattice net). in: holomorphic c=8 boundary net out: (E8)_1 [E] 1. LIT-A, LIT-B, LIT-C TYPED. three established theorems, each with statement, reference, typed input and output. [E] 2. CHAIN COMPOSES. output(LIT-A) = input(LIT-B) and output(LIT-B) = input(LIT-C), so the three compose into 'invertible bulk => (E8)_1' as a single logical chain (verified by matching the typed in/out slots). [E] 3. ALL THREE LEGS ESTABLISHED. none of LIT-A/B/C is the open step -- each is a cited theorem; Route A imports a COMPOSITION, not a black box. [O] 4. THE ONE OPEN HYPOTHESIS. the input of LIT-A, 'the raw quasi-free seam bulk is invertible (SRE)', is the single open premise -- and it is the SAME geometric input as Route B's Flat-Away (the raw seam is flat away from the marks). So Route A reduces SEAM.EQUIV.01 to one cited stack modulo one hypothesis shared with Route B. [E] 5. NON-CIRCULAR WITH ROUTE B. the stack uses only AQFT/topological-phase literature (no DtN/Steklov geometry), so it meets Route B only at the shared open hypothesis, not in its machinery (the v286 import firewall holds). Status: [E] the typed citable stack + the composition + the shared-hypothesis isolation; [O] the one open hypothesis (seam-bulk invertibility = Route B's Flat-Away). A documentation/typing module that turns Route A's import into a precise theorem stack; it does NOT prove the hypothesis. Python (stdlib).
