Certificate and scope

The event uses the interface theorem subject to its assumptions; it does not supply those assumptions. No $\mathrm{Enter}$ fires at the event. Physical patch diameter is not a computational block-diameter certificate, and the channel retiming theorem does not move the event past a record-dependent or geometry-dependent gate.

The central incidence is the type A exchange pattern of tHooft1993 (Section 3.1). This is not the full transition catalogue. The patch contains no particle or nontrivial spacetime monodromy. Ambient identity words also do not imply that every intrinsic slice angle sum is $2\pi$.

different collapsed quadrilateral. For comparison, let

For $t\ne 1$, the boundary order $ABCD$ has crossing segments $AB,CD$. Its convex hull has area $2|1-t|$, so the whole patch collapses. The proposed replacement $AB$ has length $2$, rather than being born from zero. With spacetime time $T=t$, the $A,B$ trajectories are timelike and $C,D$ trajectories null. This is not the certified exchange.
