STM32 emulation (open-core, runs via libqemu-arm in the backend worker):
- backend: stm32_lib_manager + stm32_worker (GPIO, USART, I2C/SPI device models
reusing the ESP32 slaves, live sensor updates), arduino_cli STM32 branch,
start_stm32 simulation route.
- frontend: Stm32Bridge + Stm32BluePill(/BlackPill) web components (Wokwi SVGs),
board kinds, Interconnect/boardPinMapping/boardProtocols wiring, example
projects (blink, serial, I2C BMP280/MPU6050/DS1307/SSD1306/weather, 7-seg,
RGB, button, switch, stepper, cross-board interconnect).
- Raspberry Pi 4/5 board elements + thumbnails.
Pro board gating (generic OSS->Pro seam; entitlement logic lives in the overlay):
- lib/proBoardGate.ts: isProBoardKind (STM32 + every QEMU Raspberry Pi),
installBoardGateImpl/boardGateDecision, triggerProUpgradePrompt.
- PRO badge on those boards in the component picker; gate at the picker add +
the run backstop (startBoard).
- backend/app/services/board_access.py: server-side enforcement seam for the
simulation WebSocket; STM32/Pi unavailable -> Pro-framed message.
- desktop: generic QemuDownloadPrompt + Stm32QemuPrompt (download-behind-license,
mirrors the ESP32 prompt).
- .gitignore: never ship libqemu-* binaries in the public image.

Replaces the native OS-modal update dialog (which blocked the editor
and looked dated) with a non-intrusive bottom-right toast that
appears 30 s after app mount when the Tauri updater finds a newer
release.
State machine:
idle → no update detected, render nothing
available → "Update available - Velxio Desktop X.Y.Z" + Install/Later
downloading → progress bar with "X.X / Y.Y MB (NN%)"
installing → "Installing X.Y.Z... will restart automatically"
error → error message + Retry/Dismiss
Click "Install and restart":
1. downloadAndInstall() streams the full signed installer (~70 MB)
2. Tauri verifies the minisign sig against the embedded pubkey
3. Replaces the install in-place
4. Auto-relaunch (the app exits and reopens on the new version)
"Later" dismisses for the rest of the session (sessionStorage flag).
A close+reopen re-checks. Manual re-check via the menu still works.
Companion change in velxio-prod flips tauri.conf.json
updater.dialog from true to false so our custom toast is the only
update UI - no double-prompting.
Files:
- frontend/src/desktop/UpdateAvailableToast.tsx (new): the component
- frontend/src/desktop/desktop.css: toast styles + slide-in animation
- frontend/src/desktop/index.ts: mount alongside GraceBanner +
Esp32QemuPrompt in the existing sidePanelRoot

Adds the frontend half of the v0.3.0 desktop paid model. The Tauri
shell (in velxio-prod) emits velxio://license-required when the
license gate refuses to spawn the sidecar; this commit teaches the
OSS desktop overlay to react.
- LockoutOverlay.tsx (new): full-screen modal with three variants
(no_credential / tampered / expired). Sign-in or paste-key
resolves it via restartApp().
- DesktopWelcomePage.tsx: new grandfather variant - "you have N
days to keep using Velxio Desktop" + "Continue without signing in".
- GraceBanner.tsx: rewrite with pre-expiry tones (5d amber, 24h
red, dismissible), polling every 10 min while document visible,
separates pre/post-expiry messaging.
- Esp32QemuPrompt.tsx: signup gate for grandfather users (ESP32
binaries are not part of the grandfather grace) + inline progress
bar driven by velxio://esp32-qemu-progress events.
- index.ts: rewires on getGateInfo() at first paint to decide
welcome vs lockout vs nothing; installs license-required listener
+ 10-min foreground polling for the locked transition.
- tauriBridge.ts: adds GateInfo type, getGateInfo(), restartApp().

Three coordinated changes that fix the "Waiting for browser…" hang
and unblock first-launch UX on the Tauri desktop build:
1. desktop/index.ts — DON'T mountWelcome unconditionally on first
launch. Before, an empty keychain (no key yet) forced the
welcome / sign-in screen on top of the editor, gating 100% of
the app behind an account. Now the editor opens directly:
compile + run + sim + save .vlx all work for free (they're
upstream OSS features), and the license check still runs in
the background just to populate state for the GraceBanner
(which shows for invalid keys — locked, tampered, in
soft/hard grace). Pro-only features (ESP32 QEMU download,
agent IA) prompt for license at use time, where it actually
matters. Matches the "try before you buy" expectation a
desktop install creates.
2. desktop/tauriBridge.ts — rewrite `openExternal` to try every
known IPC path in cascade order and log via the desktop debug
file which one worked. The previous implementation invoked
`plugin:shell|open` with `{ path: url }`, which silently
failed (no ACL match + wrong arg shape) and fell back to
`window.open`, which inside a Tauri webview is a no-op for
external URLs — the browser never opened. New cascade:
plugin:opener|open_url (paired with tauri-plugin-opener which
ships in this revision), then plugin:shell|open with both
`{ path, with: null }` and `{ url }` shapes, then the
window.__TAURI__.shell / opener high-level wrappers that
specific Tauri 2.x flag combos expose. Each attempt logged
via the dlog helper so the next operator can see exactly
which path was used (or that all failed) without devtools.
3. desktop/menu.ts — new `navigate-route` action type. Routes
bundled in the SPA (DocsPage, ExamplesPage, AboutPage) that
used to open velxio.dev in the system browser now navigate
in-window via history.pushState + popstate (mirrors the
locale-switch handler). Respects the current locale prefix
so `/examples` from `/es/editor` lands at `/es/examples`
instead of jumping back to English.

Two new modules under the existing desktop/ subtree, both no-op
outside a Tauri runtime (tauriBridge.listen / .invoke fail gracefully).
desktop/menu.ts — listens for the `velxio://menu` event the Rust
shell emits from the native menubar (Velxio Desktop / File / Edit
/ View / Help, full menu defined in
pro/desktop/src-tauri/src/menu.rs). Internal actions handled
directly here: Save .vlx and Open .vlx via utils/vlxFile, Toggle
Serial Monitor via useSimulatorStore, Check for Updates via the
tauri-plugin-updater global. The rest (new-project, Find,
Toggle File Explorer) re-emit as window CustomEvent so the owners
of that UI state can subscribe without pulling this module in.
desktop/log.ts — `dlog(message, extra?)` round-trips a line to a
Rust `write_debug_log` command that appends to
`<app_data_dir>/desktop-debug.log`. Packaged Tauri apps have no
devtools or stdout capture, so this is the only way to see what
the webview did when a user reports a bug. Falls back to plain
console.log when the command isn't registered (older shell).
mountDesktop() now installs the menu listener and dlog's its own
start — useful as a "did the desktop module even load" smoke marker.

New `frontend/src/desktop/` module loaded only when VITE_DESKTOP=true.
Hosts the Tauri-bound UI that pure OSS doesn't need:
- tauriBridge.ts typed invoke / listen / openExternal / beginSignIn
wrappers with no-op fallbacks for `vite dev` outside
the Tauri webview.
- DesktopWelcomePage.tsx sign-in flow with browser handoff +
paste-key fallback; listens for
`velxio://auth-completed` from the shell.
- GraceBanner.tsx renders soft/hard grace banners driven by
`license_status` + `velxio://license-status`
emits from the background checkin loop.
Toggles `body.vlx-desktop-readonly` so the
editor's Save / Compile buttons disable
themselves via CSS in hard-grace.
- Esp32QemuPrompt.tsx one-time download modal when the user picks
an ESP32 board on a fresh install.
- index.ts mounts welcome conditionally and the side
panels unconditionally.
- desktop.css shared styles.
All entry points are no-ops outside Tauri so the existence of the
folder has zero effect on the OSS build.
