the mixed interface has an exact shape

EstablishedIntegrator

Follows from declared assumptions and has an inspectable certificate. joins several typed results while letting the weakest edge set the claim.

Exact assertion

With the equal-weight vertex pairing the interface is positive definite, has determinant nine and discriminant group \(\mathbb Z_9\). It carries a natural permutation-invariant cubic, but the product obtained by projecting coordinate multiplication back to the zero-sum space is not Jordan. The result is therefore a definite transfer lattice, not an octonion, Leech, \(E_6\) or \(E_8\) identification and not a physical A8 symmetry.

What this commits us to

The stated conclusion follows inside the declared model. Reusing it elsewhere requires carrying the same object definitions, assumptions and typing.

Logical anatomy

Scope

Chapter “The admissibility frontier”, section “the mixed interface has an exact shape”. This is assertion 2 of 4 in that section.

Evidence posture

Audit the declared carrier, assumptions and certificate. The result is exact only within that written scope.

Research move

joins several typed results while letting the weakest edge set the claim.

Verification route

  1. Recover the declared objects and assumptions from the controlling documents.
  2. Check the calculation, construction, obstruction or stopping rule on those same objects.
  3. Compare the source conclusion with the exact assertion above; do not strengthen its verbs or enlarge its domain.
  4. Apply the status rule and retain every named external dependency.

What would move or defeat this claim

Locate a mismatched definition, an omitted assumption, a failed certificate step or a counterexample on the declared carrier.
