the missing form was already latent

Exact assertion

The signature-(2,3) form used by the rectangular Spin(2,3) closure can now be derived, up to scale, from selector data that predates that closure: a symplectic form and its uniquely compatible positive metric define a complex structure, whose action on primitive two-forms splits five real directions into two and three with opposite wedge-pairing signs. This is a real anti-retrofit advance, but it does not identify those abstract sectors with physical ports. The native positive adjoint still admits two completions: one closes to compact SO(5), the other to noncompact SO(2,3). Worse, the unbroken selector has no invariant map from its two-sector to its three-sector. The remaining experiment and theory target is therefore one independently calibrated common-carrier map that reproduces a selector operation at the ports, treats the observed cross-channel as symmetry breaking, and fixes the noncompact reverse-channel phase.

What this commits us to

The claim supplies a map or analogy. It becomes a derivation only after an explicit carrier-preserving map and invariant are given.

Logical anatomy

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

Provide an explicit map that preserves the claimed structure, then identify an observable consequence that the analogy alone did not supply.
