+# nostr-id-tui
+
+Boot-time terminal identity UI for n-OS-tr.
+
+Current local implementation provides a functional ncurses flow:
+
+- Main menu
+- Enter existing mnemonic -> validate -> derive account 0 `npub`
+- Generate new mnemonic -> derive account 0 `npub` -> show random confirmation positions
+
+## Local host dev loop (fast iteration)
+
+Use the wrapper script to auto-bootstrap `nostr_core_lib` (if missing), rebuild, and run in your current terminal:
+
+```bash
+./stack/nostr-id-tui/dev.sh
+```
+
+What it does:
+
+1. If `includes/nostr_core_lib/libnostr_core_x64.a` is missing, builds it with `./build.sh x64`.
+2. Configures `stack/nostr-id-tui/build-host` with CMake.
+3. Rebuilds `nostr-id-tui` for host.
+4. Runs it with `TERM=${TERM:-xterm-256color}`.
+
+Manual equivalent (if preferred):
+
+```bash
+cmake -S stack/nostr-id-tui -B stack/nostr-id-tui/build-host
+cmake --build stack/nostr-id-tui/build-host -j
+TERM=xterm-256color ./stack/nostr-id-tui/build-host/nostr-id-tui
+```
+
+## Static Docker build (musl, reproducible)
+
+This path now builds `nostr_core_lib` inside Alpine and links `nostr-id-tui` fully static against musl.
+
+```bash
+./stack/nostr-id-tui/build_static.sh
+```
+
+Output:
+
+- `stack/nostr-id-tui/build/nostr-id-tui_static_x86_64`
+
+## Notes
+
+- Uses upstream helpers from `nostr_core_lib`:
+  - `nostr_secure_memory`
+  - `nostr_bip39_ui`
+  - `nostr_generate_mnemonic_and_keys`
+  - `nostr_derive_keys_from_mnemonic`
+- Identity-agent IPC and systemd boot wiring are intentionally out of scope for this step.
