v0.4.0

Footprints rounded to 8 decimals (#4), so a build on linux and one on macOS write the same item
bytes, and the monthly update publishes only what changed. Every item's geometry and bbox
moved, and the collection's spatial extent with them. Nothing else changed: the build listed the
same 175,278 files and built the same 174,282 items as 0.3.0. Against a copy of the 0.3.0 bucket,
all 2,439,948 coordinates equal the published value rounded to 8 decimals, the largest shift is
5e-9 degrees (under 1 mm), and no other key of any item differs (scripts/catalogue_compare.py,
rewritten for this release). Published 2026-10-14 and verified IN SYNC (174,282 ids equal in
both directions, every body digest-equal). Before registration, stacs register --dryrun found
exactly the expected drift: all 174,282 items changed, the collection changed, the queryable
missing, nothing missing or orphaned.

• lidarbc:delivery is declared as a queryable in stacs.toml (#5), so CQL2 clients can
  discover the key at /collections/stac-pointcloud-bc/queryables. stacs moves from v0.1.1,
  which predates queryables (stacs 0.1.2), to v0.2.0. This release's registration loaded it, and
  stac-elevation-bc's queryables are unchanged (its own declaration is
  NewGraphEnvironment/stac_elevation_bc#62).
