Finite encodings and reversible composition

Fix a clock precision $p_{\mathrm{c}}\ge 1$ and report precision $p_{\mathrm{r}}\ge 0$. Endpoint parameters are encoded exactly as

The two zero germs have separate mode codes. A report for one of the 24 finite slots is

with zero for inactive slots.

All compact endpoints have spatial norm at most four. An induced spacelike edge length is at most the spatial endpoint distance, hence at most eight. Therefore $p_{\mathrm{r}}+4$ bits per report are sufficient.
