src-tauri/fuzz: nmh_session drives a whole kestrove-nmh connection through
Broker::serve (framing, outer JSON, pair_init/pair_confirm/open/msg); frame_read
checks read_frame. 8 min each (2.5 M / 2.7 M execs): no findings.

- Builds and runs (tauri build --debug); placeholder icons; persistent VaultCore::open in the
OS app-data dir; Secret Key remembered on the device; tray keeps the app serving the extension.
- Auto-lock: idle (system idle on Windows/macOS, in-app activity on Linux), screen lock, sleep.
- Local IPC for kestrove-nmh: 0700 dir + 0600 Unix socket with peer-uid checks; Windows named
pipe (first instance, local only, user DACL, client SID check) behind cfg.
- Pairing channel: X25519 → HKDF → 6-word fingerprint confirmed in both UIs, per-connection
session keys, AES-256-GCM with strict counters. Test vectors shared with kestrove-browser.
- Broker: query/fill/totp/save with origin re-checks; pairing and save prompts in the UI.
- kestrove-nmh relays ciphertext only; native-host installers for Linux/macOS/Windows.
- Tests: unit tests, tests/nmh_stdio.rs (real kestrove-nmh over stdio), examples/test-host.
