Could you build this?
Partial A basic disk visualizer can be built quickly, but writing a high-performance scanner in Rust that correctly resolves hard links, parses APFS file system quirks, and matches POSIX `du` parity without crashing or lagging takes real systems programming.
What it would actually take: The core requires a high-performance multithreaded systems language implementation (Rust using `crossbeam` and low-level POSIX filesystem APIs) tailored specifically for Apple's APFS file system, handling inodes, clones, and hard links accurately. A native macOS UI (SwiftUI via FFI or Tauri) must integrate to safely handle macOS system permissions (Full Disk Access) and trash interactions.
