No Knobs Principle

Once the sector template is in place, inter-sector couplings are no longer free dials. At each primorial depth M_d, the coupling

κ(Sector_i,Sector_j)=f_ij(iota_tau,M_d)

is canonically determined by the master constant and the depth data. The scope is intentionally narrow in this compact note: Book III’s No Knobs covers the 10-entry primitive-sector coupling ledger, while this paragraph uses only the inter-sector/export consequence. It is not a claim that every later numerical physics readout has already been theorem-proved at this stage. Book IV and Book V instantiate the sector grammar and expose the empirical readouts.
