+-- Step 1: Add new column
+ALTER TABLE knowledge_bases ADD COLUMN IF NOT EXISTS storage_provider_config JSONB DEFAULT NULL;
+COMMENT ON COLUMN knowledge_bases.storage_provider_config IS 'Storage provider config for this KB. Only stores provider name; credentials come from tenant StorageEngineConfig.';
