The Discord release-notify workflow read the version from
frontend/package.json but never wrote it back, so every merge to release
announced the SAME version (the CHANGELOG ended up with two "[2.0.1]"
entries). Now, after generating the CHANGELOG and before announcing, the
workflow bumps the PATCH in frontend/package.json and commits it alongside
the CHANGELOG to release. Each merge advances the counter:
3.0.0 -> 3.0.1 -> 3.0.2 ...
Also sets the baseline to 3.0.0 so the next release is announced as v3.0.0.
To jump the major/minor, edit frontend/package.json on the release branch
(e.g. "version": "3.1.0") and the next merge continues from there.
End-to-end pipeline fixes uncovered while auditing the /examples gallery.
Each bug shipped past green unit + snapshot tests because none of those run
firmware + render LEDs. Added scripts/visual-led-test.mjs as a CDP-driven
visual harness that loads each example, runs the simulator, samples
`wokwi-led.brightness`, and asserts toggle / gradient / initial-off
invariants — exits non-zero on any regression.
Frontend simulator
- PinManager.updatePort: new optional ddrMask param. A pin is added to
`outputPins` only if the DDR bit is set, so the PORTx write that
enables INPUT_PULLUP (DDR=0, PORT=1) no longer falsely marks the pin
as MCU output. AVRSimulator now reads DDRB/C/D (0x24/0x27/0x2A on
Uno/Nano, 0x37 on ATtiny85, per-port table on Mega) and forwards it.
- AVRSimulator: pass DDR mask alongside every port-listener fire.
- BasicParts pushbutton{,-6mm}: seed pin HIGH in attachEvents so
`digitalRead()` returns HIGH while idle. avr8js doesn't auto-simulate
INPUT_PULLUP — without this the firmware reads LOW from boot and
thinks the button is permanently pressed (the "LED is always on,
pressing does nothing" UX bug).
- connectMcuEdgesToService: suppress synthetic digital edges on pins
with active PWM, AND subscribe to onPwmChange to re-tick the netlist
on duty changes. Fade-LED now produces a true gradient (6 distinct
brightness levels across a fade cycle) instead of a binary 0/full
toggle.
- CircuitSimulationService.handleMcuEdge: replace single-slot
pendingMcuEdge with a per-pin Map. Multiple pins toggling during the
same in-flight tick used to overwrite each other; now every pin's
most-recent edge replays after the tick. Fixes Traffic-Light RED→
YELLOW→GREEN sequencing.
- NetlistBuilder: new sanitizeSpiceId() helper replaces hyphens with
underscores in V-source names. ngspice's interactive `alter` command
treats `-` as an operator and silently no-ops on hyphenated source
names, so mid-simulation MCU pin transitions stopped propagating
after the first solve. MixedModeScheduler.onMcuPinChange and
CircuitSimulationService self-heal use the same sanitizer so names
stay consistent across emit/alter/lookup. Also added a regex-based
fallback in step 2 so any board pin matching `GND.\d+` canonicalises
to net "0" — ESP32-C3 dev kits expose up to 10 GND pins and the
per-board `groundPinNames` list missed several, leaving wires
floating instead of grounded.
- collectPinStates: emit V-sources only for pins in `outputPins`, not
every wired board pin. Leaves INPUT pins (analog sensors on A0,
pull-down dividers, etc.) free for the SPICE solver instead of being
shorted to 0 V by an ideal MCU V-source.
- start.ts: extended __spiceDebug to also expose outputPinsByBoard +
nodeVoltages + pinNetMapEntries for the visual harness.
- ESP32 / RP2040 / RISC-V / C3 simulators: pass `'mcu'` source flag to
triggerPinChange / setPinState so the new outputPins tracking fires
on those boards too (was AVR-only before).
- useSimulatorStore: stopBoard/resetBoard call pm.resetPinStates() so
outputPins clears between runs; Esp32Bridge.onPinChange passes the
`'mcu'` flag in all three places it's wired.
- types/board.ts: ATtiny85 FQBN `clock=internal16mhz` →
`clock=16pll` (ATTinyCore 1.5.2 renamed the option).
Backend
- esp-idf-template/main/CMakeLists.txt: skip the
`-DLED_BUILTIN=2` fallback for esp32c3 and esp32s3 targets. Both
variants already define LED_BUILTIN in pins_arduino.h via a
self-define macro (`#define LED_BUILTIN LED_BUILTIN` + `static const
uint8_t LED_BUILTIN = ...;`). Pre-defining the symbol from the
command line expanded the static-const declaration to
`static const uint8_t 2 = ...;` — a syntax error that broke every
ESP32-C3 / S3 build (`expected unqualified-id before numeric
constant`).
Examples
- examples.ts: bulk-fix 72 wire endpoints that referenced
`componentId: 'nano-rp2040'` / `'esp32-c3'` etc. (boards that don't
exist on the canvas). Replaced with `'arduino-uno'` (the canvas
board-id convention) and converted `D<n>` pin names to `GP<n>` for
Pico-style boards. Affects pico-blink, pico-i2c-scanner,
pico-i2c-rtc-read, pico-spi-loopback, c3-blink and others.
Tests
- scripts/visual-led-test.mjs: CDP-driven harness. Default suite covers
Blink (single-pin), Button (idle-OFF invariant — catches the
INPUT_PULLUP regression), Traffic-Light (multi-pin sequencing),
Fade-LED (PWM gradient — ≥3 distinct levels), RGB-LED (≥3 PWM pins
driven). Run via `npm --prefix frontend run test:visual` against a
Chrome on `:9222` + vite on `:5174` + backend on `:8001`.

pro/frontend/src/pro/components/admin/DataTable.tsx (introduced in
the pro analytics dashboard work) already imports ColumnDef/useReactTable
etc. from @tanstack/react-table. The dependency was missing because
an earlier velxio-prod commit (e1dfc5f) added it locally but the
matching upstream package.json change was never pushed. Adding it
here unblocks the prod docker build.
K (frontend-tests.yml reinforced):
• Matrix node-version: [20, 22] — catches Node-version-specific bugs
• Cache the 24 MB ngspice WASM by hash — saves ~10s/run
• `npm run tsc` step (continue-on-error: pre-existing strict errors
in unrelated test files; tracked but not blocking)
• `npm run build` — Vite production build smoke catches Rollup/
Vite-only failures that vitest doesn't see (manualChunks wiring,
dynamic import paths, asset resolution)
• `npm run test:coverage` + upload as artifact (Node 22 only)
L (package.json scripts):
• `tsc` → `tsc -b`
• `test:libraries` → `RUN_LIBRARY_TESTS=1 vitest run
src/__tests__/library-compile.integration.test.ts`
I (library-compile nightly):
• New `.github/workflows/library-compile.yml` — 5 AM UTC cron +
workflow_dispatch. Not on PRs (slow + external deps).
• Sets up arduino-cli + caches `~/.arduino15` cores (avr, esp32,
rp2040 — ~500 MB).
• New `library-compile.integration.test.ts` — iterates every
example with `code` + `libraries` + a known FQBN. For each:
arduino-cli lib install → write .ino → arduino-cli compile.
7 examples currently match (epaper-displays).
• Gated behind RUN_LIBRARY_TESTS=1; default vitest skips the file.
Final tally: 1853 tests pass (was 1461 before Phase 1d-tests — +392
new sub-tests across 8 new test files + 1 new workflow). Vite build
green (2.68 MB main chunk, unchanged).

The mixed-mode migration's endgame. After this commit there is ONE
SPICE solver path in the codebase — the vendored ngspice WASM via
SolverPort, behind both NgSpiceWorkerAdapter (production browser) and
NgSpiceNodeAdapter (Vitest Node). Zero hybrids; zero legacy left to
maintain.
Deleted production files:
• simulation/spice/CircuitScheduler.ts (200ms-poll legacy)
• simulation/spice/SpiceEngine.ts (eecircuit-engine wrap)
• simulation/spice/SpiceEngine.lazy.ts (lazy code-split)
• simulation/spice/subscribeToStore.ts (legacy solve loop)
• simulation/spice/connectLegacySolverToMixedMode.ts (bridge)
• simulation/spice/connectMixedModeSchedulerToStore.ts (feature flag)
Deleted tests (no longer cover any live code):
• connect-legacy-solver-to-mixed-mode.test.ts
• connect-mixed-mode-scheduler-to-store.test.ts
• spice-rectifier-live-bootstrap.test.ts
Migrated 6 tests off the deleted `circuitScheduler.solveNow` API to
the new `__tests__/helpers/solveInput.ts` (same shape, backed by
NgSpiceNodeAdapter).
`useElectricalStore` rewritten as a pure state container:
• setSolveResult(snapshot) — atomic publish from the service
• paused / setPaused — UI control unchanged
• reset — project unload
• REMOVED: triggerSolve, solveNow, setDebounceMs, scheduler hook
• REMOVED: dependency on SpiceEngine.lazy preload
EditorPage now mounts a single `startSimulation()` from
`simulation/spice/start.ts`, which constructs
CircuitSimulationService + ADC bridge + MCU edge bridge. Four
useEffect calls collapsed to one.
`circuitVerifier.ts` (production) and `runNetlist.ts` use an
environment-aware factory: Web Worker in browser, in-proc WASM in
Node tests. `/* @vite-ignore */` keeps the Node adapter chain
(node:fs, node:url) out of the browser bundle while still letting
Node resolve it dynamically.
Removed `eecircuit-engine` from package.json dependencies.
`collectPinStates` extracted to its own module so the service doesn't
depend on the (now deleted) subscribeToStore.ts.
Verification:
• 1392/1392 tests pass across 103 files (28 pre-existing skips).
• `tsc --noEmit` clean.
• `vite build` succeeds (27 s, only the existing chunk-size
warning that pre-dates this work).
Phase 1c — COMPLETE.

Replace Unix-only shell one-liner (mkdir -p / printf / cp -r) with a
Node.js ESM script (scripts/copy-monaco.mjs) that works on Windows,
macOS and Linux alike. The script still writes public/monaco/.gitignore
to keep copied assets out of git.
- postinstall now writes a '*' .gitignore into public/monaco/ so the
copied monaco-editor assets are never tracked as untracked files
- Also add public/monaco/ to frontend/.gitignore as a belt-and-suspenders
fallback for the same reason
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.
Changes that ship to OSS — all benign for self-hosters, but most are
extension points the velxio-prod overlay (and any private fork) needs to
plug an in-editor AI chat into the page.
Editor:
- 3-way view-mode toggle (code / both / circuit) in the unified toolbar.
Lets users hide a pane to give a right-docked sidebar (e.g. the AI
chat overlay) more breathing room. Persisted in useEditorStore.
- Default file explorer narrower (210 → 165 px); min 110.
- Removed the redundant `tb-board-pill` (icon + "Editing: X" tooltip);
the BoardSelector dropdown elsewhere already shows the active board.
- Inlined Import/Export/Upload-firmware buttons; the 3-dot overflow
menu gave up too much discoverability. Removed dead overflow state.
Simulator:
- Fix: global Delete/Backspace handler in SimulatorCanvas no longer
fires when the event target is an INPUT/TEXTAREA/SELECT/contentEditable
— affected any in-page text field, not just the chat overlay.
Overlay extensibility:
- New `data-velxio-slot="agent-chat"` at the bottom of EditorPage so
pro overlays can portal a chat panel into the editor without
forking the page.
- vite.config.ts: preserveSymlinks=true when VITE_PRO_BUILD is set.
Lets local-dev junctions (overlay tree → frontend/src/pro) resolve
bare imports back to the OSS node_modules without resolving symlinks.
Deps:
- Added react-markdown + remark-gfm (rendered chat output) and
@google/genai + zod (overlay agent loop). Tree-shaken from the OSS
bundle when no pro code imports them.
gitignore:
- Ignore backend/app/pro/ and frontend/src/pro/ junctions used by
developers running a private overlay against the OSS dev server.

Foundation
- Add 7 token CSS files in src/tokens/ — semantic colors, 4-pt spacing,
Apple-HIG type ramp, radius/elevation/motion/z-index scales.
- Refactor src/index.css to import tokens and remap legacy aliases
(--accent, --bg, etc.) onto the new --color-* semantics so existing
components keep rendering during migration.
- Drop the duplicate font-family from src/App.css; body inherits from :root.
- Global *:focus-visible ring backed by --color-focus-ring (WCAG 2.4.7).
Webfonts (self-hosted)
- Add Inter.var.woff2 (variable, OFL) and JetBrainsMono.var.woff2 to
public/fonts/. Preloaded in index.html with crossorigin.
- Old stack -apple-system kept as fallback so Mac users still get SF Pro.
- Fixes cross-OS rendering inconsistency (Win/Linux/Android were falling
back to Segoe UI / Roboto, breaking the type grid).
Component primitives
- New src/components/ui/{Button,Card,Input}.tsx + .css. Built on the
semantic tokens, ready for incremental migration of .ap-* CSS classes.
Lucide icons
- Replace 6 inline SVG icon components in LandingPage (IcoChip / IcoCpu /
IcoCode / IcoZap / IcoLayers / IcoMonitor) with lucide-react imports.
Aliased so call sites are unchanged. ~80 lines of inline SVG removed.
- IcoGitHub kept bespoke (filled glyph, brand-correct).
Marketing assets
- Convert top 8 boards to transparent PNG + WebP at 1x / 2x:
Arduino Uno, Nano, Mega 2560, Pi Pico, Pi Pico W, ESP32-C3,
ESP32-DevKit-V1, XIAO ESP32-S3.
- Migrate matching cards in LandingPage and Velxio2Page to <picture>
with WebP > PNG > SVG fallback. Other 8 boards keep <img src=*.svg>
for now (Raspberry Pi 3B, ESP32-CAM, etc.).
- Refresh og-image.png — same canonical URL, new content (4 hero boards
+ branding instead of generic logo card).
- Fix latent bug in LandingPage: ESP32 DevKit V1 card was loading
esp32-devkit-c-v4.svg; now uses esp32-devkit-v1.{webp,png,svg}.
Build verified: npm run build:docker succeeds, 246 SEO pages prerender.

Resolves several install pain points reported by users (#108, #120) and
removes the obligatory upstream-clone step that confused contributors and
slowed down every Docker build.
Install fixes:
- nginx: server_name → catch-all default_server, drop Debian's stock site
so reverse-proxied users no longer get the "Welcome to nginx" page.
- entrypoint: auto-generate SECRET_KEY at first boot, persisted under
data/.secret_key. backend/.env is now optional in docker-compose.yml.
- backend: add greenlet>=3.0.0 (SQLAlchemy async dep that was missing on
some Python builds — caused uvicorn startup failures on WSL).
Wokwi libs come from npm:
- @wokwi/elements 1.9.2, avr8js 0.21.0, rp2040js 1.3.2 are pinned in
frontend/package.json. Vite aliases removed.
- Dockerfile.standalone no longer clones avr8js / rp2040js / wokwi-elements
/ wokwi-boards. Frontend stage is just COPY + npm install + build:docker.
- Board SVGs vendored under frontend/public/boards/ (10 deduped against
existing files, 2 truly new). third-party/wokwi-* clones become reference-
only credits — generate-component-metadata.ts skips gracefully when absent.
Production config split out:
- docker-compose.prod.yml, deploy/nginx.prod.conf, nginx-host-velxio*.conf,
update-third-party.bat removed. Production deployment lives in its own
repo: https://github.com/velxio/velxio-prod (host nginx + HTTPS + backups
+ pinned upstream commit).
Verified locally: 1161 frontend tests pass, build:docker completes clean.

The directory grew well beyond Wokwi-only contents: it now hosts
lcgamboa's QEMU fork (qemu-lcgamboa), Espressif's esp32-camera, the
ngspice WASM build, fritzing-parts, picowi, an alternative QEMU
(qemu-esp32), the 100_Days_100_IoT_Projects examples repo, and
Wokwi's own avr8js/rp2040js/wokwi-elements/wokwi-features/wokwi-boards.
"wokwi-libs" was misleading — half the contents have nothing to do
with Wokwi. "third-party/" is the standard convention for vendored
external dependencies.
Mechanical changes:
Path rename:
wokwi-libs/ → third-party/
update-wokwi-libs.bat → update-third-party.bat
docs/WOKWI_LIBS.md → docs/THIRD_PARTY.md
Submodule reconfiguration:
.gitmodules — 4 path= and section names updated
.git/modules/wokwi-libs/ → .git/modules/third-party/
each submodule's .git file rewired to ../../.git/modules/third-party/<name>
Reference updates (~80 files): vite.config.ts aliases, Dockerfile
COPY paths, GH Actions workflow steps, build_qemu_*.sh, all
docs/* and test/*/autosearch/* entries that mention the path,
package-lock.json file: dependencies, .gitignore patterns,
sitemap.xml + index.html SEO blurbs, scripts/generate-component-*,
.dockerignore, .idea/vcs.xml. Bulk replaced both `wokwi-libs/`
(path) and bare `wokwi-libs` (textual mentions in docs/comments).
Verified:
- npx tsc -b --noEmit produces no new errors related to these paths
- vite.config.ts aliases now point at ../third-party/avr8js etc.
- All 4 git submodules (avr8js, rp2040js, wokwi-elements,
wokwi-features) are linked under third-party/ with their
worktrees re-populated and config files referencing the new path
- `grep -r wokwi-libs` returns zero hits outside node_modules,
.vite, frontend/dist, third-party/ (upstream submodule contents),
*.pyc caches, and *.dll.pre-camera rollback binaries

Track per-user, per-project, and per-board usage to inform pricing tier
decisions. Adds an admin dashboard with KPIs (DAU/WAU/MAU, totals,
success rate), time-series charts for compiles/runs, board family +
FQBN breakdowns, "board diversity" pie chart (key freemium signal),
top users/projects, and per-country breakdown via Cloudflare's
CF-IPCountry header. Admin can now also view private projects.

event_type, board_fqbn/family, country, error_kind, duration_ms)
- Aggregate counters on User (total_compiles/runs/errors, last_active,
signup_country, last_country) and Project (compile/run/update counts,
last_compiled/run timestamps) kept in sync by MetricsService for O(1)
dashboard reads
- 10 admin endpoints under /api/admin/metrics/{overview, timeseries,
boards, board-diversity, top-users, top-projects, countries,
users/{id}, projects/{id}}
- POST /api/metrics/run for client-side run telemetry
- Country detection via cf-ipcountry header (no DB / no API calls)
- Auto-migrations in lifespan for legacy DBs
Frontend:
- recharts-powered Dashboard tab with KPI cards and 4 charts
- New Boards tab with per-family + per-FQBN breakdown
- Country column with flag emoji on Users tab
- Top countries card on Dashboard
- compileCode now forwards project_id; Run button reports via WS
