Chapter 13: The No Knobs Principle
The 4+1 sector template derived in the relevant chapter provides the organisational blueprint for the four primitive sectors and the ω-coupling that mediates between them. The Parity Bridge Theorem singled out the weak sector as the unique carrier of the E₁ → E₂ transition. One structural question remains: how strong is each inter-sector coupling? The answer, established in this chapter, is that there is no freedom in the coupling strengths at all. Every coupling is a canonical rational function of the master constant ι_τ = 2/(π + e) evaluated at a specific primorial depth. The theory has no adjustable parameters—no knobs to turn. This is the No Knobs Principle, the capstone of Part II. We catalog all ten coupling entries in the No Knobs Ledger, preview the physical consequences (under strict conjectural scope), and close Part II with its export contracts.
