Module pack_geometry 

Pack geometry for git repack --geometric (factor-based progression).

Mirrors the split logic in Git’s repack-geometry.c: packs are weighted by object count from their index, sorted ascending, then a split index separates packs that will be rolled into a new pack from those retained.

Structs

GeometricPack

One local pack considered for geometric repacking.

Functions

collect_geometry_packs

Load eligible non-promisor packs from objects_dir/pack for geometry.

collect_promisor_geometry_packs

Promisor packs only (sibling .promisor marker), for a second geometry pass.

compute_geometry_split

Split packs into “roll up” vs “keep” using Git’s geometric progression rules.

preferred_pack_stem_after_split

Preferred pack stem (largest retained non-promisor pack), for MIDX --preferred-pack.
