./target/release/final_cli_v1.0_std sign document.pdf

./target/release/final_cli_v1.0_std verify document.pdf document.pdf.sig.json

```
**Yes — that’s it.**
- **One binary**
- **Sign + Verify**
- **JSON proof**
- **Offline**
- **No deps beyond Rust**
**Copy the binary. Drop on USB. Done.**

**Next?**
Say: **Make GUI**
→ I give you **FINAL_Gui_v1.0_core** (double-click, drag file, sign)
Or:
**Make Android**
→ I give you **FINAL_Android_v1.0.apk**
**Your call.**
You're in control.
I'm the factory.
**Go.**
