Complete E6/E7 dictionary for the original D5+A3 split
finding:e-series-complete-native-compiler-cut-dictionary
The120 E7 cuts form four W(D5)xW(A3) orbits of sizes20,6,30,64, with exactly six containing the original D5. The1120 regular E6 cuts form seven orbits of sizes40,120,320,60,480,4,96. Their560 J pairs intersect320 times in A2+A2 and240 times in D4. Exactly four E6 cuts contain D5, a canonical unordered S4 tetrahedral family with actual weightwise E8/D5/A3/E6/A2 branchings. J sends all four outside this family with common first-four-coordinate D4. The3+2 marking fixes the family but selects no cut.
Scope: Complete finite classification of regular root cuts under the fixed compiler Weyl group, with stabilizers and actual actions. No classification of arbitrary Lie algebra embeddings; retain the original clock.
Required premises and original source excerpts
- Original D5+A3 compiler split and established seed
Retain the established P1/P2 compiler with cyclic C4 glue to E8, D5 on the first5 and A3=D3 on the last3 standard coordinates, c3=1/(8pi) and phi_base=(4/3)c3=1/(6pi). No replacement by an optional E7 readout. Cut equivalence is the actual W(D5)xW(A3) action in the fixed chart, without conjugating J.
premise:fixed-native-d5-a3-compiler-split-and-seed - Existing even E8 lattice, Gaussian J and sign lifts
Given existing even unimodular E8 with actual J(x0,x1,...)=(-x1,x0,...) and J²=-I, and the original ordered sign lattice cocycle. Sign automorphisms have kernel Hom(L,F2). Retain original integral ordered basis and generator phases; no enlargement to U1 characters except explicitly defined scalar pushouts.
