The KY-040 rotary encoder was already fully simulated (wokwi-ky-040 element + PartSimulationRegistry 'ky-040' driving CLK/DT quadrature and the SW button) and present in the catalog, but unfindable: named 'KY040', in the 'other' category, with no rotary/encoder search tags and a placeholder thumbnail. A user searching 'rotary encoder' got nothing (issue #104).
- generate-component-metadata.ts: let component-overrides.json patch category, description and tags on scanned wokwi parts (previously only name/thumbnail) -- the fields the picker category tab and ComponentRegistry.search() actually use. - component-overrides.json: ky-040 override -> name 'KY-040 Rotary Encoder', category 'input', rotary/encoder/knob tags, description, real encoder thumbnail SVG. - examples.ts: KY-040 + Arduino Uno example (quadrature read + SW reset). Regenerated components-metadata.json; searching rotary/encoder/knob now returns the KY-040. tsc clean.

The boards added in 6813891 (F103CB / F401 pill variants, F4 Discovery,
Olimex H405, Netduino 2/+2) run on the libqemu-arm backend with no
in-browser canvas example, like the existing Blue/Black Pill. Add them to
ACCEPTED_UNCOVERED so the coverage matrix passes.

useSimulatorStore eagerly imports STM32_LED from this module, so the
top-level `class extends HTMLElement` + customElements.define ran at import
time and threw "HTMLElement is not defined" under vitest's node environment,
breaking 20 test files that load the store. Guard the base class with a
dummy fallback and skip registration when customElements is absent; browser
behavior is unchanged.

Adds stm32-f4-discovery, stm32-olimex-h405, stm32-netduino-plus2, stm32-netduino2, stm32-blackpill-f401 and stm32-bluepill-f103cb, mapped to existing qemu-lcgamboa machines (netduinoplus2, olimex-stm32-h405, netduino2, stm32vldiscovery). A generic inline board renderer (no SVG) draws the Discovery/Olimex/Netduino boards from a header pin layout; the Pill variants reuse the Blue/Black Pill SVGs. Per-board onboard-LED pin and polarity via STM32_LED. One blink+serial example per board.

Add STM32 Blue Pill / Black Pill tabs to BOARD_TABS, and make getBoardFilter
honor an explicit boardFilter before the boards[] check. The STM32 examples
are authored with the multi-board boards[] format even when single-board, so
they were all bucketed under "Multi-Board" and had no STM32 filter tab.
Now they appear under their dedicated STM32 tabs (attiny85 single-board
examples authored the same way get correctly bucketed too).

STM32 Blue/Black Pill sketches failed to compile with "Platform
'STMicroelectronics:stm32' not found" because the arduino-cli STM32 core
and its board-manager URL were never set up. Add the stm32duino board
manager URL (first-run block) and `core install STMicroelectronics:stm32`
alongside the other cores so a fresh arduino-libs volume can compile STM32.

stm32-bluepill and stm32-blackpill are Pro features emulated on the backend
via the licensed libqemu-arm QEMU lib (no in-browser canvas engine, same as
the Raspberry Pi boards), and their gallery examples are intentionally not
shipped to the free tier. Add them to ACCEPTED_UNCOVERED so the board-kind
coverage matrix passes — this was missed when the boards were introduced.

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.

Sixth overflow-menu item, Pro-badged. Dispatches
velxio-pro-replay-record-toggle (projectId in detail) which the pro
overlay handles — plan check, board-type check, start/stop the
recorder. OSS build has no listener → silent no-op.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Two unrelated polish fixes.
espidf_compiler: headers that resolve to an arduino-esp32 CORE lib
(WebServer, WiFi, …) were correctly skipped from the user-lib merge but
then fell through to a scary "Library for <X> not found — build may
fail" warning — even though the build succeeds because the symbols are
compiled into the core. Now logs an accurate "provided by arduino-esp32
core — already compiled in, not merging". Same treatment for core
headers that aren't standalone lib dirs (Udp.h, IPAddress.h,
WiFiUdp.h, …) via a new _CORE_ESP32_HEADERS allowlist.
SimulatorCanvas: the WiFi badge's "open IoT gateway" click now consults
an optional window.__velxio_iot_gateway_open_gate__ hook before opening
the gateway tab. A private overlay can install it to gate the gateway
behind a paid plan and show an in-place upgrade modal instead of dumping
a 402 page in a new tab. OSS builds have no hook → opens normally. The
check is synchronous so it doesn't trip popup blockers.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Adds a generic gating hook so a private overlay can restrict the IoT
gateway proxy to paid plans without the OSS image carrying any plan
logic. register_iot_gateway_gate() installs an async callback that
returns None to allow or a detail dict to block; the OSS default (no
overlay) allows everyone, and a failing gate fails OPEN so the gateway
can never be taken down by a buggy overlay.
gateway_proxy() calls the gate first. When blocked it content-
negotiates the 402: browsers (Accept: text/html — the frontend opens
the gateway via window.open) get a small styled upgrade page with a
link to /pricing; programmatic fetch/XHR callers get the JSON detail.
No behaviour change for the open-source image — the gate is a no-op
there.

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.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
LandingPage footer gains a "For schools" link sitting between Pricing
and About — gives institutional visitors a discoverable path to the
Classroom landing without burying it inside the FAQ.
seoRoutes.ts adds the /classroom entry (priority 0.85, monthly
changefreq) so the auto-generated sitemap picks it up on every build.
Bonus: getSeoMeta('/classroom') now returns the institutional title +
description if any other code wants to read it programmatically.
The static public/sitemap.xml is not committed — `npm run generate:sitemap`
overwrites it during the Docker build, so any hand-edit would be wiped.

The home page's pricing section was still showing the dropped Phase 0
shape (Free / Pro $15 / Pro Max $35) instead of what /pricing and the
billing backend actually serve (Free / Maker $7 / Pro $19).
- Replace the middle card from "Pro $15" → "Maker $7" (CTA "Start
Maker") + the right card from "Pro Max $35" → "Pro $19" (CTA
"Subscribe to Pro"). "Most popular" badge moves to the now-Pro
card (still the upsell sweet spot).
- i18n keys renamed in lockstep: tiers.pro → tiers.maker, tiers.pro_max
→ tiers.pro. Updated in all 9 locales (en/es/pt-br/fr/de/it/ja/ru/
zh-cn) with translated copy that mentions the actually-shipped Pro
perks (private projects, GitHub Sync, BOM CSV, schematic PNG,
watermark-free embed). The Spanish line about "Maker" is left as
the loanword so it stays consistent with /pricing.
No backend changes — quota.py PLANS was already correct.

Adds the proposed llmstxt.org file under frontend/public/ so the SPA
nginx serves it at https://velxio.dev/llms.txt. ChatGPT-driven traffic
has had the highest engagement of any channel (82% session quality per
GA), so feeding the AI crawlers a curated, machine-readable summary
is high-leverage: the model gets accurate tier prices, supported
boards, comparison framing vs Wokwi / Tinkercad / Proteus, plus FAQ
answers — instead of stitching together a fuzzy view from blog posts.
Notable departures from the original phase-5 draft:
- Tier shape is the shipped one (Free / Maker $7 / Pro $19), not the
proposed Pro/Hobbyist + LemonSqueezy variants that never landed.
- Geo-pricing section dropped (Phase 2 deferred — same reason).
- Supported boards list reflects the actual MCU emulator coverage in
the latest velxio image, not the aspirational roadmap.
- GitHub Sync and embed iframe (D3.5) are now first-class features.

Fifth item in the overflow menu next to Sync to GitHub. Free for
all users (no PRO badge); dispatches velxio-pro-share-prompt with the
current project id so the overlay's ShareModal can render the direct

Dispatches velxio-pro-upgrade-prompt's sibling event
velxio-pro-github-sync-prompt with the current project id. The pro
overlay's GithubSyncModal listens and runs the four-state link/sync
flow (no-pro / not-connected / not-linked / linked) inline without
leaving the editor.
Pure OSS builds have no listener so the click is a silent no-op —
those users can't have linked repos anyway.

Replace the hard /pricing redirect on 402 with a window-dispatched
'velxio-pro-upgrade-prompt' event so private overlays can surface an
in-editor upgrade modal instead of bouncing the user out of context.
Move BOM, Schematic image and firmware upload buttons into a "..." More
menu next to the existing Export ZIP icon, freeing two button slots in
the inline toolbar. Mark the two premium items with a small "PRO" pill
so free-plan users know they're gated before they click — Notion- /
Linear-style discoverability cue.
Also wire Import + Export ZIP to fall back into that same menu once the
toolbar container drops below 320 / 280 px (container queries on the
editor pane width). Mobile / narrow-split layouts keep full feature
parity through the dropdown instead of overflowing into a horizontally
scrolling row.

- Updated the introduction to reflect new features and capabilities of Velxio, including multi-board support and enhanced simulation features.
- Expanded the roadmap to include detailed sections on implemented features, in-progress tasks, and future plans, highlighting new boards, languages, and simulation improvements.
- Added a new desktop app documentation file outlining features, installation, licensing, and troubleshooting for the Tauri-based desktop version of Velxio.
Phase 1 D1.4 — replaces the binary public/private toggle in ShareModal
with three radio-button-styled options. Optimistic UI: every option
renders for every user; the backend's 403 (with structured
visibility_not_allowed detail) redirects to /pricing?from=visibility_X
so the pricing page can lead the right pitch.
Why optimistic-then-redirect instead of hiding/locking options:
1. Discovery — Free / Maker users SEE Pro unlocks Private. That's the
exact conversion signal the pricing page is trying to surface.
2. Discovery without surprise — the locked click goes to /pricing
with a hint, not a dead modal.
3. Less plan-coupling — this upstream component doesn't need to know
about the pro overlay's plan store. Backend is the only source of
truth for what's allowed.
Touched:
- ShareModal.tsx: full rewrite as a 3-option picker with badges
(Maker / Pro) on the gated options.
- projectService.ts: ProjectResponse / ProjectSaveData now declare
`visibility?: 'public' | 'unlisted' | 'private'`. is_public stays
declared for backward compat with old callers.
- useProjectStore.ts: CurrentProject gains `visibility?`; setVisibility
accepts EITHER the legacy boolean OR the new enum and keeps both
fields coherent.
- common.json (4 locales): new editor.share.visibility.{publicLabel,
publicHint, unlistedLabel, unlistedHint, privateLabel, privateHint}
+ editor.share.updateFailed.
Backend gating + DB migration are in the velxio-prod pro overlay
(commit referencing this submodule pointer).

Front-end half of the schematic image export. New camera-icon button in
the editor toolbar between BOM and Upload-Firmware. Handler:
1. POSTs to /api/pro/projects/{id}/screenshot.png (server renders the
canvas with headless chromium, returns a PNG).
2. 402 → /pricing?from=screenshot_export
3. 401 → /login with redirect-back
4. 422 → friendly "add at least one component" toast
5. 200 → blob download with Content-Disposition filename
6. The "rendering..." toast surfaces during the 5-10 s of headless
chromium time so users know to wait, not click again.
i18n key editor.toolbar.exportScreenshot added in en/es/pt-br/zh-cn.

Phase 3 D3.1 — front-end half of the BOM export. The toolbar gains a
new spreadsheet-icon button next to the existing project-export button.
On click:
1. POST is NOT used — the backend endpoint is GET-based and streams a
CSV. We just open the URL.
2. 402 (Pro-required) routes the user to /pricing?from=bom_export
so the page can show the right upgrade narrative.
3. 401 routes to /login with redirect-back.
4. 200 triggers a Blob download with Content-Disposition filename.
i18n key editor.toolbar.exportBom added in en/es/pt-br/zh-cn — the
" — Pro" suffix on the tooltip hints at the gating without forcing the
user to discover it only on click.
The button is shown to everyone, not hidden by plan. Free/Maker users
clicking it gets the 402 route to /pricing, which is intentional — that
is the upgrade-discovery funnel we want, not a silent locked icon.

Phase 1 D1.8 — the home-page hero leads with three defensible
differentiators Velxio has that the dominant alternative doesn't:
- AI agent integrated (Wokwi has none)
- Works offline as a desktop app (Wokwi is cloud-only)
- AGPLv3 open source (Wokwi is proprietary)
Subtitle and trustLine rewritten across all four shipped locales
(en, es, pt-br, zh-cn). No layout change — the LandingPage.tsx
component renders both strings already.
The competitor name isn't mentioned anywhere — the user comparing
side-by-side does the math themselves. Anchoring on the USPs makes
the eventual /pricing visit ("Maker $7 = AI included") land in
context instead of cold.

The quota-exhausted modal (rendered by the velxio.dev pro overlay when
a free user hits the daily AI cap) was hardcoded English. The modal is
seen by users from CN/BR/MX/CO/AR/PE/IN — the audiences most likely to
bounce on English-only UX. This adds the four key languages.
Keys:
titleFree — "You've hit today's free limit"
titlePaid — "You've reached your daily limit"
bodyFree — explainer + Pro upgrade pitch (interpolates cap/proCap/multiplier)
bodyPaid — explainer for paid users who hit their own tier's cap
today / thisMonth / resets — stats labels
ctaUpgrade — primary CTA ("Upgrade to Pro — $15/mo")
ctaSeePlans — fallback CTA for non-free users
ctaWait — secondary "Wait until reset"
Upstream-only change — the velxio-prod overlay's AgentChatPanel.tsx is
wired to consume these via useTranslation in a separate commit.

Same root cause as the previous test fix in 3e38397 — upstream commit
d64eebc (fix(stop): reset CPU to PC=0) added a hardResetPinStates() call
to useSimulatorStore.stopBoard. The vi.mock factories in these 6 ESP32-
adjacent test files only exposed updatePort/onPinChange/getListenersCount,
so any test path that hits stopBoard crashed with "is not a function"
once the real prod code called the new method.
Each gets a single-line addition: this.hardResetPinStates = vi.fn();
Verified with full vitest run: 127 files pass, 2,005 tests pass, 0 failures.

1. multi-board-integration.test.ts — PinManager mock was missing
hardResetPinStates(). Upstream commit d64eebc (fix(stop): reset CPU
to PC=0) added that method to PinManager and useSimulatorStore.stopBoard
calls it, but this test's vi.mock factory never exposed it. Result:
"TypeError: getBoardPinManager(...)?.hardResetPinStates is not a function"
even though the optional chain looks safe — the chain only short-circuits
on null/undefined, not on a non-function property.
2. vitest.config.ts — was missing the @velxio alias that vite.config.ts
defines. defineConfig from vitest/config does NOT auto-inherit from
vite.config.ts; the alias has to be re-declared. Without it, overlay
tests importing @velxio/store/useEditorStore failed with "Cannot find
package '@velxio/...'" even though the build (which DOES inherit the
alias) resolves them fine.
Verified: full set of 3 previously-failing tests now pass cleanly
(multi-board-integration: 43 passed, snapshot: 0, pinIntrospection: 10).

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.
Brings hardware flashing into Velxio Desktop. Per-board "Flash to
real board" entry in the canvas context menu opens a modal that
enumerates USB serial ports, lets the user pick one, then
streams arduino-cli upload output live until the board is flashed.
Backend (Phase D1) — backend/app/api/routes/flash.py (new):
POST /api/flash/upload (multipart: board_id, port, fqbn,
program_format, program)
→ SSE stream of {phase, line?, progress?} events
→ final {phase:'done', success, elapsed_ms, error?}
- Wraps `arduino-cli upload -p <port> -i <file> --fqbn <fqbn> -v`
so AVR (avrdude), ESP32 (esptool), RP2040 (picotool), SAMD
(bossac) all share one code path — arduino-cli internally
dispatches by FQBN.
- Per-port asyncio.Lock prevents two simultaneous flashes from
fighting over the same /dev/ttyACM0.
- Allow-list of FQBN prefixes (arduino:avr, ATTinyCore:avr,
rp2040:rp2040, esp32:esp32, arduino:samd) so a typo can't
cause a confusing arduino-cli error.
- Format allow-list (hex / bin / uf2 / elf) drives the temp
file extension - arduino-cli uses the extension to route to
the right uploader.
- 8MB hard cap on the uploaded program (real sketches are
well under that; protects against a runaway frontend).
- X-Accel-Buffering: no header so nginx doesn't hold the SSE
chunks until the flash completes.
Frontend (Phase D3):
- frontend/src/services/flashService.ts (new):
async generator streamFlash() yields parsed SSE events.
Handles the base64-vs-text gotcha (compile returns hex_content
as text but binary_content as base64; for binary formats we
atob() into a Uint8Array before posting so the form upload
sends actual bytes, not the base64 ASCII).
- frontend/src/components/simulator/FlashModal.tsx (new):
Three-state UI: picking (port dropdown), flashing (progress
bar + live log), success/error (verdict + retry).
Empty-ports state shows a Linux dialout-group hint.
- SimulatorCanvas.tsx: board context menu gains "Flash to real
board" entry, gated on isTauri() + presence of compiledProgram.
Hidden in web (WebSerial is a separate sprint).
- tauriBridge.ts: SerialPortInfo type + listSerialPorts() helper
that invokes the Rust shell command added in Phase D2.
The sidecar already has arduino-cli on PATH (per
`pro/desktop/sidecar/main.py::_expose_bundled_arduino_cli`), so
no installer changes are needed — flash works the moment the
0.4.x desktop bundle ships with these commits.
Plan + remaining phase tracked in project/hardware-flashing/.
D2 (Rust serial enum) committed separately as a Tauri-shell-only
concern; D4 (manual smoke matrix with real boards) requires
physical hardware so it stays a follow-up.

The desktop Tauri wrapper drops the downloaded libqemu-xtensa.<ext>
inside the directory it exports as VELXIO_QEMU_PATH. The sidecar
previously only checked the dedicated QEMU_ESP32_LIB env var (full
path) plus a fixed file beside the module, so the in-app installer's
output was invisible — adding an ESP32 to the canvas right after
install reported "unavailable" until the sidecar was restarted.
Two changes:
1. New _resolve_lib() helper checks QEMU_ESP32_LIB first, then
VELXIO_QEMU_PATH/<lib_name>, then the legacy module-adjacent path.
Both Xtensa and RISC-V flow through the same resolver.
2. lib_xtensa_path() / lib_riscv_path() functions replace the module
constants for all internal call sites (is_available,
is_riscv_available, start_instance). Resolution happens per call,
so a post-boot install is picked up without restarting the
sidecar. The LIB_PATH / LIB_RISCV_PATH constants stay for any
external readers but reflect import-time state only.
Pairs with the Tauri-side change that writes libqemu-xtensa.<ext>
directly to VELXIO_QEMU_PATH (no archive extraction).
User report after the v0.4.0 desktop agent landed:
> agente devuelve "LLM call failed: Failed to fetch"
"Failed to fetch" is a network-layer error, not 401. Root cause: the
OSS CORS allow_origins list only included http://localhost:517[3-5]
(vite dev) and settings.FRONTEND_URL. The desktop bundle runs from
either tauri://localhost (macOS/Linux) or http://tauri.localhost
(Windows) - both cross-origin to velxio.dev - so the browser
blocked the agent's POST /api/pro/agent/llm preflight before the
backend ever saw it.
Added all three Tauri scheme variants to the allow list. After this
lands + a backend restart the desktop agent's fetch reaches the
real /api/pro/agent/llm and the dual-auth dep from v0.4.0 Phase 1
gets to do its job (Bearer license-key → resolved User → quota
check → upstream LLM proxy).
Origins added:
tauri://localhost # macOS / Linux (Tauri 2.x default)
http://tauri.localhost # Windows (Tauri 2.x default)
https://tauri.localhost # older Tauri 2.x releases
allow_credentials stays True - the existing cookies-from-web flow
still works, the Tauri origins just don't have any cookies to send.

#208 — stale binary executes after compile error
EditorToolbar.handleCompile: on failed compile, clear the active
board's compiledProgram so a subsequent Run can't silently execute
the previous successful build (which doesn't match the editor any
more). The Run gate already short-circuits on !compiledProgram and
forces a fresh compile.
#209 — compile terminal kept stale messages across runs
EditorToolbar.handleCompile: setCompileLogs([]) at the top of the
handler. Previously logs from the prior compile lingered, making it
hard to tell new errors / warnings apart from old ones.
#210 — desktop File > New Project did nothing
desktop/menu.ts: the menu action used to dispatch a CustomEvent
nobody listened to. Replaced with a real `newProject()` function
that stops the running simulation, removes every board (also drops
the bridges + wires touching them), clears components / wires,
loads the default Blink sketch into the editor, clears project
metadata, and wipes the compile output. Confirms first if there's
unsaved work on the canvas.
#211 — deleting the only board made every other component
unresponsive (wires still worked)
SimulatorCanvas.tsx::interactionRunning: the old expression
treated boards.length === 0 as "boardless electrical mode is
running" — which suppressed the property dialog on click and made
non-sensor components look frozen. Fixed by also requiring
useElectricalStore.submittedNetlist !== '' before flipping to the
boardless-running branch. SPICE has to have actually solved at
least once for the mode to engage.
#212 — ESP32 Support 404 with no actionable message
desktop/Esp32QemuPrompt.tsx: catch the raw "download HTTP 404" /
"not found" upstream error and reword it to "ESP32 support is not
yet available for your platform. The Velxio team is preparing
this build - try again in a few days, or use Arduino/RP2040
boards in the meantime." The real fix is server-side (the velxio
team needs to publish a qemu-xtensa.tar.gz for the user's
platform into the asset bucket and update esp32-qemu/latest.json).
Tracked in project/desktop-agent-v040/ follow-ups.
All five fixes verified with `tsc --noEmit` clean and the existing
25-test vitest suite green.

The previous fix preserved display state on Stop so Resume could pick
up the multiplexed frame seamlessly — but that's Pause semantics, not
Stop. On a real Arduino, hitting the physical Stop is cutting power:
the next Run must boot from setup(), not continue at the saved PC.

- calls sim.reset() (was sim.stop()) — CPU back to PC=0
- calls hardResetPinStates() (was the soft resetPinStates) — clears
cached states AND notifies listeners so 7-seg / NeoPixel / LCD
blank out instead of freezing on whatever was lit.
Reset and Stop are now the same cold-boot semantics; Reset still
additionally clears serial output + baud rate. The soft
resetPinStates() helper stays for internal SPICE-classification-only
paths that don't want listener fan-out.
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.

The previous fix rotated overlay hotspots but the pivot was off by
+6px in each axis, which manifested as a 12px X-offset for a 90°
rotation (because (I - R) maps (6,6) to (12, 0) for R = 90° CW).
The wrapper top-left in container-local coords is -wrapperOffsetX,
not -(6 - wrapperOffsetX). The container origin already sits INSIDE
the wrapper's padding+border by exactly wrapperOffsetX/Y; we have
to back out by that same amount, not by 6 - that amount.
Visual verification on https://velxio.dev/example/esp32-pwm-led-rgb:
overlay centers of rotated resistor now match the rotated pin tips
exactly (was 12px off in X).
Reporter on GitHub: after rotating a component the WIRES followed
the pin tips (already fixed in the (6,6) offset commit) but the
clickable connection boxes stayed in the unrotated layout —
visible misalignment between the rotated component and its
hotspots, no way to start a fresh wire from a rotated pin.
Root cause: PinOverlay renders as a SIBLING of the DynamicComponent
wrapper, not as a child. CSS rotation on the wrapper doesn't reach
the overlay div, so its child pin boxes stay at the unrotated
(pin.x, pin.y) coordinates.
Fix:
- Plumb component.properties.rotation from SimulatorCanvas into
PinOverlay as a new `rotation` prop.
- In PinOverlay, capture wrapper.offsetWidth/Height when reading
pinInfo and apply the same rotation matrix the wire calculator
uses (pivot at wrapper center, transform-origin: center center).
- Use the rotated (pinX, pinY) for both the visual `left/top` AND
the canvas-coord passed to onPinClick, so wires that get started
from the hotspot anchor at the rotated tip too.
Also align the default wrapperOffsetX from 4 to 6 (padding:4 +
border:2 on each side of the DynamicComponent wrapper). The
previous asymmetric (4, 6) was the same 2px X bias we fixed in
pinPositionCalculator a few commits back; the overlay was reading
its own copy of the bad number and putting hotspots 2 px left of
the pin tip on unrotated components too. Board paths that pass
wrapperOffsetX/Y = 0 explicitly are unaffected.
All 29 vitest tests in the rotation + simulator suites pass.
Two related changes for the v0.4.0 desktop-agent rollout:
- include glob now also matches `../../pro/frontend/src/pro/**/__tests__/`
so the agent-overlay tests in velxio-prod are discovered when this
config is used from a velxio-prod checkout. On pure-OSS clones the
glob has nothing to match - harmless.
- server.fs.allow extended to `..` and `../..` so Vite's filesystem
sandbox doesn't reject the cross-project test paths with
"Cannot find module '/@fs/...'".
No behavior change for OSS-only contributors. velxio-prod gets the
agent's `desktopAuth` unit tests picked up automatically by
`npx vitest run` in this directory.

v0.3.x main.tsx explicitly REFUSED to load @pro when VITE_DESKTOP was
true ("desktop owns its own license + auth UI"). v0.4.0 brings the
AI agent into the desktop bundle, so the refusal needs to relax for
that one use case.
New routing inside the if(VITE_PRO_BUILD) branch:
- VITE_DESKTOP also set → load @pro/desktop_index (slim entry that
only mounts AgentChatPanel + DiagnoseCompileButton, no analytics
/ sessions / billing / admin / save overrides - those expect
velxio.dev cookies the desktop has no way to send)
- VITE_DESKTOP not set → load @pro/index (existing web behavior)
VITE_DESKTOP alone (no pro) still loads zero overlay - that's the
pure-OSS desktop build path for self-hosters who don't have the
pro source tree at $PRO_OVERLAY_PATH.
Companion commit in velxio-prod creates @pro/desktop_index, adapts
the agent client for license-key Bearer auth, and updates
build-frontend.sh to pass both flags.

Reporter feedback after 7aca3db: pressing Stop on the uno-7segment
example turned the 7-segment off, and pressing Start again left
random segments lit / no number at all. The previous fix made
resetPinStates() notify every listener with (pin, false) on both
Stop and Reset, which was right for Reset (full reboot) but wrong
for Stop:
- On Stop the AVR CPU is just paused. Internally it still has
PORTD=0xFF (or whatever the last drive was).
- resetPinStates blanked the pinStates cache + fan-out LOW
notifications. Display turns off, fine.
- On Start the CPU resumes from where it paused. avr8js's port
listener fires only for bits that CHANGED relative to its OWN
oldValue (which still holds the pre-stop value). If oldValue
matches the live register, no pinChange event fires for that
bit, and the display has no signal telling it to come back on.
Split the API into two methods:
resetPinStates() — soft cleanup, drops outputPins only. Used by
stopBoard. Cached pinStates and visual state
stay so the resume picks up where it left off.
hardResetPinStates() — full cleanup, drops outputPins + pinStates
and fan-outs (pin, false) to listeners.
Used by resetBoard (CPU starts at PC=0,
firmware re-drives every pin from setup()).
Updated the test helper clearAllPinManagerState to call
hardResetPinStates between tests so the same-state short-circuit in
triggerPinChange doesn't suppress fresh events.
All 32 vitest tests pass (AVRSimulator, interconnect-routing,
dual-arduino-software-serial, pin-position-rotation).
Self-hosted feedback: a user on Orange Pi 5B copied the README quick-
start `docker run` line and then couldn't find the container with
`docker logs` because the command didn't pass `--name`, so Docker
assigned a random adjective-noun name. Same friction as filing an
issue with no container id.
Aligns the quick-start with the detailed "Option A" block lower in
the README that already had --name velxio. Also points at
`docker logs -f velxio` so the next person knows how to tail without
hunting for the auto-generated name.
Two paired bugs that surfaced on the Reset button.
(1) 7-segment / NeoPixel / LCD freeze on last pattern after Reset.
resetPinStates() was wiping the pinStates cache + outputPins set
silently — no listener notifications fired, so visual components
that update on pinChange kept rendering whatever segments were
lit at the instant the user pressed Reset. Now we snapshot every
pin that was HIGH before clearing and fan out a synthetic
(pin, false) to each registered listener. Stateful displays
redraw cleanly to all-off; passive listeners (analog sensors,
debounce-only buttons) ignore the synthetic LOW and recover on
their next real write.
(2) Cross-board serial silently dies after pressing Reset. resetBoard
was unconditionally reassigning:
sim.onSerialData = (ch) => appendSerial(boardId, ch);
immediately after sim.reset(). The comment said "re-wire after
reset" but reset() does NOT clear that property — the new USART's
onByteTransmit chains through `this.onSerialData` which IS the
Interconnect wrapper. The reassignment destroyed that wrapper and
sibling-board UART forwarding (Uno TX → Nano RX) stopped working
until a full page reload. Same root pattern as the initSimulator
bug fixed in 5480052 — Interconnect's __icSerialHookInstalled
flag is on the live sim, so once the wrapper is blown away
nothing reinstalls it. Removed the reassignment and left a NOTE
so the next person doesn't reintroduce it.
Verified the AVRSimulator + dual-arduino-software-serial +
interconnect-routing test suites still pass (26 tests).
Cross-board UART forwarding silently broke for any project loaded
with > 1 board. User report: Arduino Uno → Arduino Nano serial echo
test where the Uno transmits fine but the Nano's Serial.available()
is never true.
Root cause traced live with chrome-devtools-mcp + temporary debug
logs in AVRSimulator.onSerialData setter and Interconnect:
1. loadProjectState → addBoard(uno) → createSimulator → sim.onSerialData = appendSerial
2. addBoard(nano) → same
3. setWires → Interconnect.updateWires → ensureSerialHook(uno)
wraps sim.onSerialData with a fan-out callback that ALSO pushes
to the Nano's RX queue. __icSerialHookInstalled flag set.
4. SimulatorCanvas mounts → useEffect calls store.initSimulator()
5. initSimulator unconditionally did:
simulatorMap.delete(boardId);
const sim = createSimulator(...); // ← brand-new sim
simulatorMap.set(boardId, sim); // ← Interconnect's wrapper is gone
The new sim's onSerialData is just appendSerial. The old sim
(where the wrapper lived) has been orphaned; Interconnect never
re-installs because its flag was on the discarded sim.
6. Run all boards → Uno.usart.onByteTransmit → this.onSerialData →
appendSerial (Uno's monitor shows TX) but no fan-out call →
Nano never receives anything.
initSimulator is a legacy single-board helper from the days when the
store only knew about one MCU. Multi-board flows already create
their sims in addBoard. Bail out early if a sim for the active
boardId already exists, so the legacy helper becomes a no-op when
the multi-board path has already done the work.
Verified the 3 related test suites still pass (AVRSimulator,
dual-arduino-software-serial, interconnect-routing).
