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.

- Implemented `i2c-esp32-real-firmware.test.ts` to test ESP32 I2C communication via backend and WebSocket.
- Created `load-example-transitions.test.ts` to ensure proper loading of examples between board-less and board-based contexts.
- Added `CircuitVerificationModal.tsx` to display circuit verification results before running simulations.
- Developed `circuitVerifier.ts` to perform pre-flight checks for circuit safety, identifying potential issues like short circuits and component overloads.
- Introduced minimal ESP32 I2C master sketch `esp32_i2c_writer.ino` for testing I2C transactions.
CI's Frontend Tests workflow had been failing on master for ~15 runs.
Two pre-existing issues, neither related to the SPI refactor in 8b1433d
or the ESP32-CAM work:
1. RP2040Simulator mock missing attachCyw43 method (23 test files)
PR #126 (8e769f8 "feat(multi-board): add wire-aware cross-board
interconnect router", merged 2026-04-25) added a Pico-W-specific
`sim.attachCyw43(bridge)` call inside addBoard(). The 23 test files
that mock RP2040Simulator with vi.fn weren't updated; whenever a
test path created a Pico W board the mock threw "TypeError:
sim.attachCyw43 is not a function" and aborted addBoard.
Fix: add `this.attachCyw43 = vi.fn()` to every affected mock.
Also pre-populate `this.spi = { onByte: null, completeTransfer: vi.fn() }`
so any future SPI-part tests don't trip on the new generic .spi
adapter from 8b1433d.
2. install-libraries.test.ts payload mismatch
PR #135 (b1026ec7 "library-version-uninstall", merged 2026-04-29)
extended `installLibrary(name)` to `installLibrary(name, version?)`
and now sends `{name, version: version ?? null}` over the wire.
The test still asserted `{name}` only and failed.
Fix: assert `{name, version: null}` for the no-version call.
Verified locally: 1161 passed | 1 skipped (was 1117 passed | 44 failed).
Backend E2E "Run HC-SR04 e2e test" is a separate failure that needs
its own investigation — it downloads QEMU binaries from a release and
runs real firmware compilation, which I can't reproduce on Windows.

- Modified the index file to reflect the new naming convention for Velxio components.
- Changed JSX declarations to use 'velxio-' prefix for various components.
- Updated component overrides to replace 'wokwi-' with 'velxio-' for logic gates and other components.
- Adjusted SVG generation script to use 'velxio-' prefix for BMP280 and Raspberry Pi components.
- Marked submodules as dirty in QEMU and RP2040 libraries.
- Added .prettierignore and .prettierrc.json for consistent code formatting.
- Introduced InstrumentComponent with support for Voltmeter and Ammeter, including pin information handling.
- Added board-agnostic sensor registration methods in RP2040Simulator.
- Enhanced ComplexParts to handle LEDC PWM duty updates for ESP32.
- Updated ProtocolParts to check if the simulator handles sensor protocols natively, delegating to backend if applicable.
- Introduced pre-registration of sensors in useSimulatorStore for ESP32 to prevent race conditions.
- Added tests for ESP32 DHT22 sensor registration flow, ensuring proper delegation and fallback mechanisms.
- Created tests for ESP32 Servo and Potentiometer interactions, verifying PWM subscriptions and ADC handling.
