The explorer toggle tooltips (Hide/Show file explorer) and the header's
Share-project title were raw English — now keyed and translated in all
nine locales, same common2.json home as the menubar strings.
The floating corner box sat ON TOP of the file tree — create enough files
and the last rows scrolled underneath it. The account + language block is
now the explorer panel's footer (VS Code style): the tree scrolls above
it, always. When the explorer is collapsed the block falls back to the
small fixed corner box, so account and language stay reachable.
The standalone language globe becomes a logged-out affordance: once the
pro auth slot renders its signed-in marker (data-auth-user), a :has()
rule hides the globe — signed-in users change language inside the
account menu, where the pro overlay now hosts it.
The header's backdrop-filter makes it a containing block for fixed
descendants, so the corner box's bottom:8px resolved against the 45px
header — measured at y=-4, sitting on the logo. Portaled to <body>, where
fixed means the viewport. The auth slot keeps working: pro's injector
finds it by attribute wherever it lives.
IDE-style: a small fixed box in the explorer's quiet bottom corner holds
the language switcher and the account button (pro keeps injecting it into
the same data-velxio-slot, just relocated). The autosave dot rides next
to the menus, and the header's Share button is gone — File > Share/Embed
already covers it.
The point is width: emptying the header's right side gives the toolbar
the last ~150px it needed, so the single-row layout now holds down to
~1400px WITH the chat docked — which is exactly the reported 1440x900
case. Tight-fallback thresholds drop accordingly (1400/1060/1040).
Desktop-editor variant only; marketing pages and mobile keep their
header untouched.
With the marketing nav gone from the editor header, its middle was ~700px
of dead space at 1280 while the toolbar occupied a whole second 38px bar.
The unified toolbar strip now fills that middle through a new AppHeader
editorToolbar slot: one 44px row where there used to be 44+38 — a full
row returned to the code and the canvas.
The strip keeps its own class names, so everything that keyed on them
keeps working untouched: the container queries, the docked-chat
padding-right, and the internal flex-wrap. When it truly cannot fit, the
strip wraps and the header grows (height: auto on the modifier class)
instead of clipping or overlapping; brand and the right-side controls
stay pinned to the first line. Inside the header the strip drops its own
background and border so it reads as one bar, not a box within a bar.
Mobile keeps the previous layout (no strip; the mobile tab bar remains).
The open-source build now ships exactly its product surface: /editor, the
examples gallery (/examples, /examples/:id) and the per-example editor
(/example/:id). Landing, about, pricing, docs, the 14 keyword-targeted
simulator landings and the v2/v2.5/v3 showcases move to the private
overlay, registered through the same registerProRoutes seam that already
carries login/admin/classroom.
Root behaves per build: an overlay that registers an index route claims
'/' (velxio.dev keeps its landing); otherwise '/' redirects to /editor.
The redirect waits for the overlay import to settle — same contract as
markProExamplesSettled — so a velxio.dev visitor is never bounced into
the editor because the landing was 300ms away from registering.
Prerender and sitemap follow the split: entry-server pulls the marketing
page map from '@pro/pages/marketing' behind a VITE_PRO_BUILD-gated dynamic
import (the proven main.tsx pattern, with an OSS stub for tsc), and
generate-sitemap lists only served routes in OSS builds (2 URLs) while
pro builds stay byte-identical — verified against a pre-migration
baseline: sitemap (37 URLs) and prerendered /, /about, /docs,
/arduino-simulator, /esp32-simulator, /v3 all identical modulo hashed
asset names. OSS prerender drops exactly the 32 marketing pages (348→316).
The OSS header slims down to match: Editor, Examples, GitHub, Discord —
the marketing links only render in pro builds, where their routes exist.
The editor Help menu links those pages absolutely (velxio.dev) in OSS,
exactly like the desktop app's Help menu.
La queja: demasiados botones en una sola fila, y en pantallas pequenas se
solapan — medido, no impresion: a 1024px Code/Both/Circuit pisaban a
Compile/Run/Stop por 9-20px y Add pisaba el chat por 29px, con el idioma y
el usuario cortados fuera del viewport.
Tres piezas:
1. En el editor, el nav de marketing (Home/Docs/Pricing/...) sobra: ya
estas dentro, y cuesta exactamente el ancho que le falta a la toolbar.
AppHeader gana la variante editorMenu — mismo mecanismo que ya usa la
build de escritorio (VITE_DESKTOP) — que oculta el nav y pinta un menu
File/Edit junto al logo. El logo sigue llevando a inicio; idioma,
autoguardado, Share y usuario se quedan.
2. File/Edit al estilo escritorio: lo que se usa cada minuto sigue siendo
boton; lo que se usa unas veces por sesion va al menu. File: nuevo
workspace, nuevo fichero, abrir, guardar, importar, exportar, BOM,
imagen del esquema. Edit: undo/redo (con su estado real del historial),
centrar vista, zoom. Las acciones viven en cierres de cuatro
componentes distintos, asi que hay un registro id->handler
(lib/editorCommands, mismo patron de seam que registerProExamples o
registerBoardBuiltins): cada dueno registra al montar y el menu invoca
por id; un item sin dueno montado se pinta deshabilitado, que ademas es
la verdad. El registro sobrevive al remontaje StrictMode (el cleanup
viejo no borra al sucesor) y tiene test de eso.
3. La toolbar adelgaza: fuera Undo/Redo (Ctrl+Z/Y siguen), fuera los
botones inline de Import/Export y sus gemelos responsivos del More
(~70px recuperados); el More queda solo con los extras pro (firmware,
GitHub, share, grabacion). El CSS responsivo de los botones retirados
se va con ellos.
Suite en verde (2300) y build del overlay verificado desde este arbol.
Search-engine indexing of public projects
- Update robots.txt to also list /sitemap-projects.xml so Googlebot /
Bingbot discover every public project's canonical /:username/:slug URL.
- Add /docs/github-sync + /classroom entries to seoRoutes.ts so the
build-time sitemap.xml picks them up.
Navigation polish
- AppHeader gains a "For schools" link between Pricing and Download.
- LandingPage's pricing section gets a slim banner under the cards
pointing institutional visitors to /classroom (visible discovery path,
not just a footer link).
- Localised header.nav.classroom + landing.pricing.classroomBanner +
landing.pricing.classroomCta across all 9 maintained locales (en/es/
pt-br/fr/de/it/ja/ru/zh-cn).
Community examples
- New CommunityProjectsGrid component lives next to ExamplesGallery on
/examples. Fetches /api/projects/featured (Pro-overlay-only endpoint)
and renders the top public projects ranked by run_count. Quietly
hides itself when the endpoint returns nothing or fails, so the OSS
build still ships cleanly.

Inserts a Download entry between Pricing and Blog in the main nav.
Routes to the existing DesktopInstallPage in the velxio-prod pro
overlay (auth gate + platform-detect + signed-licence download flow).
i18n: header.nav.download added across all 9 shipped locales
(en/es/ja/it/de/ru/pt-br/zh-cn/fr) with native translations.
Self-hosted OSS image: the route doesn't exist there, so the link
lands on the upstream router's 404 — same fallback behaviour as
/pricing already has for self-hosters. Acceptable until the OSS
side gets its own placeholder.
Three QoL fixes for the Tauri shell:
1. Hide the entire AppHeader strip in VITE_DESKTOP, not just the
marketing nav. The previous gate left the black bar painting
over the editor with the brand + auto-save + share + auth
slot, all of which are irrelevant in desktop (cloud Pro
features, license is handled by DesktopWelcomePage, the title
bar already says "Velxio Desktop"). Return null at the top so
the editor takes the full window height.
2. Splash screen during sidecar boot + Monaco hydration. Cold
launch was a 3-8 s black window — now there's an inline SVG
logo, "Velxio" wordmark, slogan, animated spinner, and a
"Starting local backend…" caption. Lives in index.html as a
fixed-position overlay with display:none by default; the inline
script reveals it only when `window.__TAURI__` is present, so
web users never see it. main.tsx fades it out (250 ms ease-out)
after two animation frames — guarantees React's first paint has
committed before the handoff, no black flash. Self-contained:
inline styles, inline SVG, inline CSS keyframes, zero external
requests.
3. Native locale switcher under View → Language. Emits
`velxio://menu` with action='set-locale' + the locale code; the
desktop/menu.ts handler navigates via history.pushState +
popstate so React Router picks it up without a hard reload
(Monaco + simulator state preserved). Locale list mirrors
i18n/config.ts::LOCALES.

The marketing nav (Home/Docs/Examples/Pricing/Blog/GitHub/Discord) and
the LandingPage hero are great for velxio.dev visitors but become
clutter once the SPA ships inside a Tauri shell — the user installed
the desktop app to land in the editor, not to read about the project.
Two small VITE_DESKTOP gates handle this:
- AppHeader.tsx hides the <nav> + the mobile hamburger that toggles
it. The brand, language switcher, auto-save indicator, share
button, and the pro overlay's auth slot all stay visible — they
carry real per-session info, not navigation.
- App.tsx swaps the `/` route's element for a <Navigate to=/editor>
so first-launch (and any future `velxio://` deep-link that lands
on `/`) goes straight to the editor.
Equivalent actions for the items being hidden live on the native
menubar that the velxio-prod overlay builds via
pro/desktop/src-tauri/src/menu.rs.

Phase 3 of the OSS / pro split — frontend side. Phase 2 already moved
the auth/DB stack out of the OSS backend; this commit does the same
for the React app. After this, the OSS image is editor + simulator
+ landing + docs only.
What moved to the private overlay (pro/frontend/src/pro/):
pages/{Login,Register,ForgotPassword,ResetPassword}Page.tsx
pages/{Admin,UserProfile,Project,ProjectById}Page.tsx
components/admin/{AdminBoardsTab,AdminDashboardTab,UserActivityModal}.tsx
components/layout/{SaveProjectModal,LoginPromptModal}.tsx
services/{authService,adminService}.ts
store/useAuthStore.ts
hooks/autoSaveImpl.ts
New seams added so OSS components stay decoupled:
* lib/proRoutes.ts — registerProRoutes()/useProRoutes() via
useSyncExternalStore. mountPro() injects the moved pages at runtime;
App.tsx subscribes to the registry, so registration after the
initial render re-renders without a Not-Found flash.
* lib/proSession.ts — registerSessionCheck()/triggerSessionCheck().
App.tsx fires this on mount instead of useAuthStore.checkSession();
pure OSS no-ops.
* lib/proSaveAction.ts — installSaveActionImpl()/triggerSaveAction().
EditorPage's Save button dispatches through this; the overlay
decides whether to show SaveProjectModal or LoginPromptModal based
on auth state. In OSS without an overlay it's a no-op today; in
Phase 4 of the split it becomes the .vlx Export entry point.
OSS-side rewrites:
* App.tsx drops the 8 page imports + 8 route entries; uses
triggerSessionCheck() instead of useAuthStore directly.
* AppHeader.tsx drops the user/login/register block entirely. The
header-auth slot (introduced in Phase 1) now stays empty in OSS
and gets filled by the overlay's portal mount.
* EditorPage.tsx drops useAuthStore + SaveProjectModal +
LoginPromptModal imports. The Save handler is now triggerSaveAction().
* LandingPage.tsx drops the dead UserMenu component (defined but
never rendered) + its useAuthStore imports.
* main.tsx drops the side-effect import of hooks/autoSaveImpl — the
impl lives in pro now and self-registers via mountPro().
Build config:
* vite.config.ts adds @velxio alias → src/. Lets the overlay import
upstream modules (lib/proRoutes etc.) by stable name regardless of
whether it's symlinked (local dev) or COPYed (Docker).
* preserveSymlinks now gated on VITE_PRO_BUILD only (not on serve
mode). Needed so Rollup keeps the overlay logically inside src/pro/
during local junction-based builds.
Build verification:
* OSS-only: 20-ish routes, no /login, /admin, /:username — 285 SEO
pages prerendered. Bundle drops ~80-120 KB.
* OSS + overlay: full 38 routes (30 upstream + 8 from registerProRoutes),
HeaderAuth dropdown injected via slot, save action wired to the
overlay's modal flow.

First phase of the OSS / pro split. Goal: open the seams so the auth/DB/admin
stack can move into the private overlay (Phase 2-3) without the routes that
stay in OSS (compile, libraries, simulation, iot_gateway) having to know.
Backend
-------
* New app/core/hooks.py — registry for record_compile, get_current_user_id,
and lifespan startup tasks. Each hook is a no-op by default; overlays
call register_* in register_pro(app) to plug in a real implementation.
* compile.py now imports only from app.core.hooks. Drops the direct deps on
app.core.dependencies, app.database.session, app.models.user, and
app.services.metrics. Route signatures use `Depends(get_current_user_id)`
instead of `Depends(get_current_user)`; the metric helper passes user_id
through rather than a User instance.
* compile_chip.py drops the unused _current_user Depends entirely.
* main.py wraps the auth/DB stack import in try/except. When it succeeds
(today's behavior on velxio.dev), an adapter bridges record_compile and
get_current_user_id to the existing app.services.metrics + dependencies,
and the create_all + ALTER TABLE migration block runs via a registered
lifespan_startup hook. When it fails (the post-Phase-2 OSS image), main
logs "running stateless" and skips registering anything — the routes
still load and behave as no-ops for metrics + always-anonymous for auth.
Frontend
--------
* useAutoSaveProject becomes a skeleton: one useState + one useEffect that
delegates to an installed AutoSaveImpl. installAutoSaveImpl() replaces
the impl without changing hook count, so React's rules-of-hooks stay
satisfied even after the impl moves out of OSS.
* New hooks/autoSaveImpl.ts holds the original logic (debouncing, dirty
detection, owner eligibility, fetch keepalive on unload), refactored to
emit() instead of useState. It self-registers at module load; main.tsx
imports it for the side effect.
* AppHeader wraps the entire user-vs-login UI in a data-velxio-slot
="header-auth" boundary. Today the OSS UI still renders inside the slot
— the overlay can portal-inject additional items now, and in Phase 3
the slot becomes the sole owner of header auth UX.
Behavior is identical on velxio.dev (pro overlay imports everything
successfully, every adapter wires up). The change is purely structural:
deleting the auth/DB modules tomorrow no longer crashes OSS at import.

The /pricing page exists (PricingPlaceholder upstream, real PricingPage
portal-mounted by the private overlay) but had no entry in the top nav.
Adds 'pricing' to header.nav in all 9 locales (de, en, es, fr, it, ja,
pt-br, ru, zh-cn), wires the Link in AppHeader between About and Blog,
and mirrors the link in the landing-page footer.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
This is Phase 1 of multi-language support: the visible chrome (header,
footer, language switcher) and routing are wired up for all 9 locales
(en, es, pt-br, it, fr, zh-cn, de, ja, ru) — same set the blog at
velxio.dev/blog/ already supports. The Editor and the long-form
landing-page copy are still English-only and will be translated in a
follow-up.
Infrastructure
- frontend/src/i18n/config.ts: locale registry + LOCALE_META (htmlLang,
native name, og locale, dir). Mirrors pro/blog/src/i18n/config.ts so
cookie sync stays consistent.
- frontend/src/i18n/cookie.ts: read/write the velxio_locale cookie at
Path=/; Max-Age=1y; SameSite=Lax (Secure on HTTPS). The blog reads
the same cookie via an inline script in its Layout.astro.
- frontend/src/i18n/path.ts: getLocaleFromPath / stripLocaleFromPath /
localizedPath / switchLocale / blogUrlFor — match the blog's helpers
one-to-one.
- frontend/src/i18n/index.ts: i18next bootstrap. English bundle is
inlined synchronously for first paint; non-default locales are
lazy-loaded via dynamic import on demand. Initial locale is decided
in priority order URL > cookie > navigator > en.
- frontend/src/i18n/LocaleSync.tsx: top-level wrapper inside <Router>.
On every URL change loads the matching locale bundle, calls
i18n.changeLanguage, writes the cookie, and mirrors the locale onto
<html lang> and dir.
- frontend/src/i18n/useLocalizedNavigate.ts: useCurrentLocale,
useLocalizedHref, useLocalizedNavigate hooks for components that
build internal links.
Routing
- App.tsx: route table extracted to a single ROUTES array, then
registered twice — once at the root (default English) and once
nested under each non-default locale (`/<locale>/...`). Explicit
per-locale parent routes (rather than a generic `:lang` param) so
React Router never accidentally swallows a real top-level path
like `/circuit-simulator` as a locale segment.
Header / Footer
- LanguageSwitcher.tsx + .css: dropdown matching the blog's
LanguageSwitcher.astro. Globe icon + locale code on the trigger,
native names + ISO codes in the menu. Click → `switchLocale()`
rewrites the URL under the new locale; LocaleSync handles the
rest (load bundle, change language, write cookie).
- AppHeader.tsx: every nav label and the auth dropdown copy now
goes through `t('header.nav.*')`, `t('header.auth.*')`. All
internal Links wrapped with localize() so navigation stays
inside the active locale. Added a "Blog" link computed via
`blogUrlFor(currentLocale)` so /es/ → /blog/es/, etc.
- LandingPage.tsx: footer About-Velxio paragraph reads from
t('footer.about').
Translations (Phase 1 strings)
- frontend/src/i18n/locales/<locale>/common.json: nav labels, auth
buttons, footer About copy. Hand-translated for all 9 locales,
AGPLv3 / brand names preserved as-is.
Tooling
- frontend/scripts/translate-i18n.mjs: standalone Node script that
takes the en.json bundles and auto-translates them to the 8 other
locales via DeepSeek (primary) + Gemini (fallback). One LLM call
per (locale, namespace) pair. Run after extracting new strings
with `npm run translate:i18n`.
Phase 2 (deferred)
- Editor (toolbar, file explorer, simulator canvas, component picker,
library manager, error toasts) — hundreds of strings.
- Examples / Docs / About / Profile pages.
- The translate-i18n.mjs script is ready to handle these once the
strings have been extracted into JSON keys.
Three small markers (each one HTML attribute) so private overlays can
portal-inject UI into well-defined places without forking the upstream
component:
- AppHeader user dropdown: data-velxio-slot="user-menu"
Lets overlays add menu items between "My projects" and "Sign out"
(e.g. a Privacy / opt-out item).
- AdminPage tab bar: data-velxio-slot="admin-tabs"
Lets overlays add extra tabs alongside Dashboard / Users / Projects /
Boards (e.g. a Pro Analytics tab).
- AdminPage tab content area: data-velxio-slot="admin-tab-content"
Sibling div where overlay tab content can portal-render.
Generic markers, no overlay-specific code in upstream. Anyone with
private extensions can use them. The OSS build is otherwise unchanged.

The project save/load pipeline only persisted a single `board_type`, so
multi-board workspaces silently lost every board except the active one
on save, and wires referencing the dropped boards' IDs orphaned to the
canvas corner on reload. An audit of the production backup found 74/306
projects (24%) with at least one orphaned wire and 174/301 non-trivial
projects whose code was still the default Blink template — strong signal
that users save once and never re-save.
Backend
- Add `boards_json` column on `projects` with idempotent ALTER TABLE in
the lifespan migration list.
- New `FileGroup` schema + `file_groups` array on
ProjectCreate/Update/Response. Legacy `files`/`code` kept for back-compat.
- `project_files.py` now uses `{pid}/{groupId}/{filename}` subdirs via
`read_groups`/`write_groups`. Legacy flat layouts are auto-promoted on
read; legacy single-list `files` only updates the active group, leaving
other boards' files intact.
- `_persist_files_from_body` honors file_groups → files → code priority.
Frontend
- `useSimulatorStore.addBoard` accepts an optional `explicitId` so
saved board IDs can be restored verbatim (wires reference IDs literally).
- New `loadProjectState({boards, fileGroups, components, wires,
activeBoardId})` action: tears down current boards, recreates from the
payload, restores file groups atomically, recalculates wire positions
on the next frame, and refreshes the Interconnect.
- `useEditorStore.replaceFileGroups` for atomic multi-group restore.
- `SaveProjectModal` and `ProjectByIdPage`/`ProjectPage` now go through
`buildSavePayload` / `buildLoadPayload` (handles pre-backfill projects
by synthesising a default board from `board_type`).
Auto-save (#useAutoSaveProject hook)
- 2.5s debounced silent PUT triggered ONLY when an authenticated user
has a `currentProject` with a UUID. State hash detects real changes
vs. UI-only churn; baseline is reset on project load so the just-loaded
state isn't immediately re-saved.
- `beforeunload` flush via `fetch keepalive: true` (supports PUT +
credentials, survives unload).
- Compact status indicator in `AppHeader` (idle/dirty/saving/saved/error).
Backfill script (one-off, idempotent)
- `backend/scripts/backfill_boards_2026_05.py` populates `boards_json`
for legacy projects. Heuristic per project, based on which board IDs
the wires reference:
Case A — wires only ref 'arduino-uno' but board_type ≠ uno:
rename id→board_type and rewrite wire endpoints.
Case B — single-board normal: keep verbatim.
Case C — multi-board: recreate one board per distinct ref, infer
kind by stripping trailing -N suffix.
Also moves any flat files into the active board's group subdir.
Stdlib-only, runs from host or `docker exec`.
Docker
- `Dockerfile.standalone` now copies `backend/scripts/` into the image
so the backfill is callable via `docker exec velxio-app python
/app/scripts/backfill_boards_2026_05.py --apply`.
Verified locally on the restored production backup (363 projects):
33 Case A, 316 Case B, 14 Case C, 135 wire endpoints renamed, 0 orphans.
Re-running the script after apply skips all 363 (idempotent).
