Abstract

We construct a self-contained local Grade S adaptation of VII-F's particle-supported slicing event to I-B's prescribed $3+1$-dimensional conical product. The background has fixed deficit $\pi /2$; its singular set is a worldsheet. An explicit product lift preserves VII-F's transverse three-to-six incidence change, the exact birth laws for six vertices, twelve edges, and six faces, and one common framed affine peripheral holonomy. The construction distinguishes a developing atlas around the defect from the compact regular laboratory in which all quantum operations occur.

The additional contribution is a complete finite operational certificate. An exact guarded metadata update has a forward decoder, a constructive NOT–CNOT–Toffoli realization with retained history, and an explicit storage and gate bound. A destructive finite clock returns both its classical code and every unnormalized conditional payload block, including arbitrary untouched references. Four exact classical evaluations are represented by finite diagonal matrices and a completely specified table-probe instrument. The resulting package separates event-time calibration from history labeling: reading an installed event code is not acquiring information from the singular worldsheet. A buffered, target-adapted causal route transports the surviving payload, location/history data, and classical control record without changing the complete instrument.

Two useful diagnostic conclusions are proved explicitly. Intrinsic lengths and areas alone cannot determine the exact event guard, even before rounding, because they are constant throughout the incoming epoch. Also, matching classical records leaves a possible residual discrepancy of trace distance $1/2$. These features make the package a reproducible finite test case for separating geometric consistency, finite readout, and physically scheduled implementation. The classical incidence event and the general channel principles are not claimed as new in themselves. The contribution is their dimensionally explicit, supported assembly with checked interfaces. No metric emergence, singular detector, Einstein dynamics, continuum-field acquisition, quantum Ward identity, or inherited quantum response coefficient is constructed.
