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.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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/`).

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

https://github.com/kritishmohapatra/100_Days_100_IoT_Projects
- Introduced `_lib.py` containing shared validators for board support and static source analysis for MicroPython projects.
- Added `conftest.py` to configure pytest for the test suite, simplifying import paths.
- Created `NOT_SUPPORTED.md` files for two projects indicating they cannot be emulated in Velxio due to lack of source code.
- Implemented unit tests for the unsupported projects to verify the presence of the NOT_SUPPORTED marker and source preservation.
The SPICE emitter already reads properties.lux (default 500, 100 nA/lux)
but the UI had no way to set it — the static dialog rejected the "range"
control type and there was no entry in SENSOR_CONTROLS for the live panel.
- Add photodiode entry in SENSOR_CONTROLS (slider 0-1000 lux)

fix: increase timeout for compilation requests to 180 seconds
refactor: call recalculateAllWirePositions after loading examples
chore: update subproject commit for rp2040js to dirty state
chore: update subproject commit for wokwi-elements to dirty state
Adds 44 SPICE mappers, 58 custom metadata entries, and 12 visual
Web Components covering logic gates, transistors, op-amps, regulators,
sources, electromechanical parts and integrated-circuit packaging.
Fase 9 — component catalog expansion
------------------------------------
- 7 logic gates (AND/OR/NAND/NOR/XOR/XNOR + NOT) as SPICE B-sources
- 8 multi-input gates (AND/OR/NAND/NOR with 3 and 4 inputs)
- 9 transistors: 5 BJTs (incl. PNP 2N3906/BC557) + 4 MOSFETs (incl.
P-channel IRF9540/FQP27P06). NMOS refactored from Level=3 W=0.1
(hangs ngspice) to Level=1 with sane W/L
- 5 op-amps: LM358, LM741, TL072, LM324 with per-chip saturation
rails + opamp-ideal
- 4 linear regulators (7805, 7812, 7905, LM317) with dropout
- 3 batteries (9V, AA, coin-cell) with realistic ESR
- Signal generator (sine / square / DC)
- 2 Schottky diodes (1N5817, 1N5819) + photodiode (lux-driven
current source)
Fase 10 — electromechanical + ICs
---------------------------------
- Relay (SPDT): coil + L + S-switch with native hysteresis +
flyback diode, inverted-control trick for the NC contact
- Optocouplers 4N25 and PC817 (LED + CCCS with CTR=0.5 / 1.0)
- 7 74HC ICs as DIP-14 packages emitting 4 or 6 B-sources per
component (first mapper pattern emitting multiple device cards)
- 3 flip-flops (D, T, JK) — digital-sim only (edge detection is
not representable in ngspice .op)
- L293D dual H-bridge motor driver
Infrastructure
--------------
- scripts/component-overrides.json gains a _customComponents[] array
that lets new Velxio-only parts survive metadata regeneration
(previously applyOverrides() could only patch wokwi-elements
components that had already been scanned)
- scripts/generate-component-metadata.ts injects custom entries
before the patch loop
- New ComponentCategory values: 'logic', 'analog', 'electromech'
- frontend/src/components/DynamicComponent.tsx PASSIVE tracing
extended from just ['resistor','resistor-us'] to 9 two-terminal
passives with per-part pin name maps
- New CI workflow test-circuit.yml runs the sandbox on push/PR
- frontend-tests.yml regenerates metadata and fails if committed
JSON is stale
- Documented 2 new ngspice gotchas in circuit-emulation-gotchas.md:
unicode in netlist titles silently hangs the parser, and
MOSFET Level=3 + W=0.1m causes .op to hang
- 164/164 sandbox tests passing in ~9 s (was 88 pre-fase-9)

- Marked submodules `rp2040js` and `wokwi-elements` as dirty to reflect local changes.
ESP32-C3 already uses the QEMU backend via Esp32Bridge, not browser-side
emulation. This adds MicroPython support by including C3 in the supported
set, adding the C3 firmware variant to the loader, and bundling the
fallback firmware binary.
Also fixes misleading type comments that said "browser emulation" for C3
boards — they actually use QEMU backend.
