2836 — Coarse Endpoint Aggregation Cancels a Nonzero Occurrence Packet

Hostile incidence test

Entry 2835 showed that an endpoint support can have a nonzero physical boundary pairing. The converse implication

$$\text{nonempty support incidence} \Longrightarrow \text{nonzero coarse readout}$$

is false.

Use the same oriented chain

$$\Gamma_\xi=[-1,1], \qquad \partial\Gamma_\xi=[1]-[-1].$$

The coarse Cayley–Menger endpoint face factors as

$$\xi^2-1=(\xi+1)(\xi-1).$$

Occurrence-resolved packet

The negative and positive endpoint occurrences carry oriented coefficients

$$r_-= -1, \qquad r_+=+1.$$

Thus the resolved route packet is

$$(r_-,r_+)=(-1,+1).$$

Neither route vanishes.

Coarse aggregation

The unweighted forgetful map

$$\sigma(r_-,r_+)=r_-+r_+$$

gives

$$\sigma(-1,+1)=0.$$

The zero coarse readout is therefore cancellation after aggregation, not absence of support or failure of both routes.

Architectural consequence

The physical selection law requires three typed stages:

$$\text{supported incidence} \longrightarrow \text{occurrence-resolved route packet} \longrightarrow \text{declared aggregation/readout}.$$

Incidence alone is insufficient. A scalar zero must be classified as either route loss or cancellation in the aggregation kernel. This is the cosmological endpoint realization of the exact route-packet distinction already found in the magnetic sector.

Scope

The result uses the unweighted boundary aggregation. A coefficient local system may supply nontrivial endpoint weights; those must be derived before applying a weighted sum. The present theorem forbids interpreting the unweighted zero as empty support.
