Signature, parameters, and return type

/**
 * App-owned persistent-file storage seam.
 *
 * This is deliberately separate from `FileSystemAdapter`: upload code needs a
 * cache directory plus base64 reads, whereas an application attachment store
 * needs a durable root plus directory creation. Keeping the contracts apart
 * avoids making every upload-only adapter pretend it can persist user files.
 */
interface DurableFileStoreAdapter {
    /** App-owned durable root URI. It must identify a directory, or return null when unavailable. */
    rootDirectory(): string | null;
    /** Creates a directory and all missing parents. Repeating the call must be safe. */
    ensureDirectory(uri: string): Promise<void>;
    /** Same discriminated stat contract as the upload file-system seam. */
    stat(uri: string): Promise<FileStat>;
    copy(input: {
        readonly from: string;
        readonly to: string;
    }): Promise<void>;
    /** Idempotent best-effort removal. */
    remove(uri: string): Promise<void>;
