Code layout

The geometric control and report block has

bits, allocated as follows:

The clock uses signed two's-complement representation, restricted to $-2^d\le j\le 2^d$. Thus $j=0$ is an exact integer-zero test.

The particle block has nine bits: six for its cell label and three fixed identifiers for the particle, deficit, and reference rest/worldline data. Their semantic values are the fixed packet ${\Pi }_{\star }$; no numerical approximation to $\pi /2$ is stored.

Set

For each original matter name reserve six location bits and six history bits. These are not charged to the geometric budget.
