Verified Copy with Post-Copy Checks

Create a module that replicates a directory tree while verifying that every copied path exists on disk immediately after the operation.

Capabilities

Copies and verifies tree

• Copying a directory with nested files from sourceDir to targetDir returns a sorted array of destination paths, and each reported path exists on disk after verification. @test

Fails when verification is missing

• If a destination file is removed right after the copy, the operation rejects with an error that identifies the missing destination path discovered during verification. @test

Respects filter exclusions

• When provided a filter that excludes certain paths (for example matching /\\.log$/), the returned path list omits those items and verification does not expect them to exist. @test

API

export interface CopyOptions {
  overwrite?: boolean;
  filter?: RegExp | ((path: string) => boolean);
}

export function replicateWithVerification(
  source: string,
  destination: string,
  options?: CopyOptions
): Promise<string[]>;
