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.
The Pico W WiFi showcase examples are a paid-overlay feature now (the WiFi
engine moved to the overlay). Read them through a build-time `@pro` seam so the
SSR prerender + gallery + sitemap include them when built with the overlay, and
OSS gets an empty stub.
- data/examples.ts: import { proExamples } from '@pro/data/proExamples' (static,
build-time) instead of the local examples-picow-wifi.ts; delete that file.
- src/__pro_stub__/data/proExamples.ts: OSS no-op (empty list) for the @pro alias.
- vitest.config.ts: mirror the @pro alias (stub by default / overlay when
VITE_PRO_BUILD) so tests loading examples.ts resolve it.
- scripts/generate-sitemap.mjs: also parse <PRO_OVERLAY_PATH>/data/proExamples.ts
when building with the overlay (the script reads example IDs from source text,
so it can't follow the alias).
- Tests: drop the picow-wifi import/usage from the 5 OSS example tests (they
validate the OSS set now); prune the 4 obsolete picow netlist snapshots. The
overlay's proExamples get their own coverage in pro/.../__tests__/.
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.

Three small, backwards-compatible hooks let anyone with private features
(velxio.dev's analytics, custom integrations, paid tiers, …) layer them
on top of the open-source build without forking files.
Backend (app/main.py):
- After standard router registration, try-import an optional `app.pro`
module exposing `register_pro(app)`. ImportError is silently swallowed
(the OSS image doesn't ship `app.pro`, so this is a no-op there).
Frontend:
- EditorToolbar: new optional `rightSlot` prop renders extra elements
after the built-in right-group buttons (mirrors the existing
`centerSlot` pattern).
- main.tsx: dynamic `import('@pro/index')` gated by VITE_PRO_BUILD env.
When unset (OSS build), the branch is dead-code-eliminated and no pro
chunk is emitted.
- vite.config.ts: `@pro` alias resolves to `src/__pro_stub__/` by default.
Private builds set `VITE_PRO_BUILD=true` and `PRO_OVERLAY_PATH=<path>`
to point at their real overlay tree.
- src/__pro_stub__/index.ts: 1-line no-op `mountPro` so TypeScript and
Vite resolvers stay happy in OSS builds.
Verified: `npm run build:docker` succeeds; `npm test` passes 1161/1162;
the OSS bundle (43 MB) contains zero references to `__pro_stub__`,
`@pro`, or `pro/index` (verified via `grep dist/`).
