2479 — Local Counterterms Occupy the Contact Port, Not the Loop-Polynomial Plane
Correction
Entry 2470 initially entertained the conditional scheme plane
and corresponding quotient ranks (7,6,5). That classification was mistyped and is retracted.
Sequence claim: seqclaim-630a43593f0f8c82605dd3d6.
Type distinction
The displayed polynomials depend on the loop coordinates (a,b,c). They are interaction-integrand directions, not spacetime-local counterterms.
A local counterterm has no loop integration variable. At fixed external kinematics, its contribution to the fixed-cycle observer lies in the loop-independent contact port.
Exact test
The direct physical-cycle score audit predeclared this port. At two generic unequal-energy samples and two independent primes,
while
Therefore
This remains true for any externally momentum-dependent local polynomial: once external kinematics are fixed, it is constant over the loop cycle.
Consequence
Arbitrary source-authorized local finite counterterms may translate the contact readout but cannot identify two rank-seven interaction classes. Hence quotienting genuine local scheme freedom preserves
The rank protection is stronger than the retracted conditional lattice. It does not require selecting a counterterm basis, and it introduces no new Carrier support.

Next falsifier
Test a nonlocal subtraction, boundary-condition change, or source-derived coefficient projection that is not confined to the contact port. Such an operation could lower rank, but it must not be called a local counterterm.
