- record that per-minor slots are unreachable from install.packages(), with
the measured size of the gap on alpine324 and noble
- choose a union index written by bincraft over an edge-side merge, and note

concatenated members)
- scope the edge script to PACKAGES* only, gated on a UNION_SLOTS variable
- move the script into the repo as a bunnynet_compute_script applied by tofu
