# CalCOFI integrated database release v2026.08.03

**Release date:** 2026-08-03

## All released geometry is tagged EPSG:4326

`ST_Point()` tags `OGC:CRS84` while `ST_Read()` over GeoJSON tags `EPSG:4326`; DuckDB refuses
`ST_Intersects` across the two, so a `sample` → `spatial` join errored outright. Geometry is
normalised immediately before the freeze — and exported locally, because most tables are uploaded
by GCS server-side copy and never pass through the connection (the check passed while the published
`grid.parquet` stayed `OGC:CRS84`). `_spatial`/`_spatial_attr` become `spatial`/`spatial_attribute`
with a real `spatial_key`. Five spatial gates added (23 → 28). Partitioned uploads use `rsync`, so a
retry resumes; full-scan parquet is clustered by cast. Rows unchanged; 2.19 → 2.16 GB.
