eight_div_2
plain-language theorem explainer
Eight divided by two equals four, linked to the eight-tick structure for kaon derivations. Modelers of strange meson masses on the phi-ladder cite this when handling the T7 octave period. The proof reduces to a native decision procedure that settles the integer arithmetic directly.
Claim. The arithmetic identity holds: $8 / 2 = 4$, recorded with the eight-tick connection.
background
The KaonMasses module derives K+, K0 masses from strange quark dominance and phi-ladder rung placement, with ratios such as m_K/m_pi near phi^2.6. The eight-tick connection points to the period 2^3 octave in the forcing chain that precedes derivation of three spatial dimensions. This identity requires no upstream lemmas, matching its zero dependency count in the module.
proof idea
The declaration uses the native_decide tactic to evaluate the integer division in a single term-mode step, confirming the result without any referenced definitions or imported lemmas.
why it matters
It anchors the eight-tick octave (T7) inside the kaon mass section and supports the chain step toward D=3. The fact supplies basic arithmetic for phi-ladder scaling without recorded downstream applications yet, leaving integration into sibling approximations such as kaon_pion_ratio_approx as an extension point.
