F3: an override drifts exactly as the same member would on a plain record. A slot the type dropped is ignored and reported by the store's schema resolution (LastSchemaMigrationReports), the one surface a plain record uses; a value that no longer decodes refuses the load, naming the variant and member. The second report surface (VariantMigrationReports, the per-variant report map, the catalog slot-name plumbing) is deleted. F4: an override for a slot the type does not have, or a value that does not decode as the member, is refused at write. Drift is for type changes after the fact, not for bad writes. F5: two overrides of one slot are refused. F2: a variant that shares an indexed value with another record is refused, naming both keys and the index (the R6 rule extended to [CultIndex]); plain record duplicate handling is unchanged. F7: a flatten now resolves against the same batch, so a base edited in that batch is in the flattened record; and the directory store refuses to load a variant page as it refuses to write one. The C1 vector's big variant now overrides its indexed code, as the unique-index rule requires. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
