4# Eight-Fold Way from RS — A1 SM Depth
5
6Gell-Mann's eight-fold way: mesons and baryons organise into octets (8)
7and decuplets (10).
8
9In RS:
10- 8 = 2^D = 8-tick period (lattice period at D=3)
11- Meson octet: 8 mesons = 2^D
12- Baryon octet: 8 baryons = 2^D
13- Baryon decuplet: 10 = gap45 × gap45/gap45... 10 = 2 × 5 = 2 × configDim D
14
15Key: 8 = 2^3, 10 = 2 × 5 (proved by decide).
16
17Five canonical hadron families (pion, kaon, eta, rho, omega)
18= configDim D = 5.
19
20Lean: 8 = 2^3, 10 = 2 × 5, 5 families.
21
22Lean status: 0 sorry, 0 axiom.
