By typing `where` directly (not through T), TypeScript's Excess Property Checking (EPC) now catches unknown field names at compile time. Previously: `findMany({ where: { notExistsColumn: 1 } })` - no error Now: TypeScript reports TS2353 for unknown fields in `where` The fix works by splitting the method signatures so that T only covers the SelectIncludeOmit part (select/include/omit - what affects return type), while `where` is typed as a direct WhereInput parameter, which triggers EPC for object literal assignments. Affected methods: findMany, findFirst, findFirstOrThrow, findUnique, findUniqueOrThrow, update, updateMany, updateManyAndReturn, upsert, delete, deleteMany.

When TypeScript inferred T from the full argument (which includes 'where'), the SelectSubset mapped 'where -> never' (not in OmitWhere). The intersection of { where: WhereUniqueInput } & { where: never } resolved to { where: never }, causing valid calls like update({ where: { id: 1 }, data: {...} }) to fail. Fix: Use the full XxxArgs type (not OmitWhere) in SelectSubset/Subset calls. Now 'where' in T maps to WhereUniqueInput/WhereInput (not never), making the intersection resolve correctly. T's constraint stays OmitWhere. EPC for 'where' in findMany/findFirst (optional where) still works. For update/upsert/delete (required data + where), EPC on where was also not effective in the original code (structural inference limitation), so no regression there.

This prevents the { where: WhereInput } & { where: unknown } intersection from collapsing to { where: never }, while still preserving TypeScript's excess-property checking on the where argument. Apply these helpers to update, upsert, updateMany, and updateManyAndReturn (the methods where T is inferred to include 'where' because the user must also pass a required field like data/create/update). Find/delete methods are unaffected: their T stays {} when no required non-where fields are present, so EPC already works via the separate { where: W } intersection. Also fix pre-existing misplaced @ts-expect-error directives in the e2e typecheck tests (error is on the excess property line, not the call site) and remove an invalid name: { not: null } filter in the valid-usage test (null is not assignable to StringFilter for a non-nullable field).
