New canvas-header Mic toggle, shown for boards whose ProBoardDef declares
builtInMicrophone (their bridge implements setMicrophoneSource). Capture
runs at the AudioContext's native rate, is decimated to 16 kHz and ring-
buffered (2 s, drop-oldest on overflow, silence on underflow - the engine
paces pulls in simulated cycles, up to 4x real time during boot boost).
No auto-start: with the toggle off the bridge's 440 Hz test tone keeps
mic sketches alive, so taking the user's microphone stays an explicit
click. The source is re-applied on every run start to survive bridge
rebuilds.
The Camera button was hard-gated to the esp32-cam board kind. The Sense now
runs its camera through the S3 engine's LCD_CAM model, fed by the same
useWebcamFrames -> sendCameraFrame path, so the toggle shows for it as well.
A ProBoardDef can declare builtInSdCsPin, and the store already built a FAT
card from the project files for it - but there was no way to put YOUR files
on that card: the upload panel only existed for the microsd-card component
and for parts with metadata.sdSlot, and boards have no properties bag.
Boards now carry sdFiles (same shape the SD panel persists everywhere else):
- BoardInstance.sdFiles, consumed by the store's Run path (card component
still wins when one is on the canvas);
- the board inspector shows the SD Card panel whenever the board kind
declares builtInSdCsPin, and routes the panel's onChange to updateBoard;
- .vlx round-trips it (serialisableBoard + payload type), and gallery
examples can pre-load the slot via ExampleBoard.sdFiles, applied by
loadExample the way the panel would.
First user: the XIAO ESP32S3 Sense (CS=GPIO21), whose board def and example
land in the pro overlay.
Right-clicking a board opened a small bespoke menu (Board Options... / Flash
to real board / Remove board) with its styling inline, while components got
the inspector. Boards now open the SAME dialog: the live board art with every
pin labelled at its real position, and an actions column that carries Board
Options and Flash instead of Rotate (boards do not rotate), with the delete
button reading "Remove board" and the wire count moved into the confirmation.
The dialog grew four optional props to make that possible without a second
implementation: extraActions, deleteLabel/deleteHint, and
previewTagName/previewAttributes - boards select their art through a
board-kind ATTRIBUTE rather than a property, so the preview needs to set it.
Also adds the boardOptions and flashToBoard strings to the nine locales: the
old menu hardcoded them in English, so those two items never translated.
205 lines of inline-styled menu are gone.
The right-click dialog was a 250px column: every pin as a text row (an ESP32
means 30 rows of scrolling), a few editors, Rotate/Delete. The picker's info
card (datasheet, brand, Buy) was a separate surface you could only reach by
hovering the catalogue. One dialog now serves both:
- ~560px, two panes: live preview + actions on the left, Properties/Datasheet
tabs on the right. The Datasheet tab IS the picker card's body -
ComponentInfoPanel was split into an embeddable ComponentInfoBody (+
useComponentDoc, and its .cip-* styles moved to their own stylesheet) so
both surfaces render one implementation.
- "Show pins" (off by default): the preview is the REAL web component,
mounted and scaled, with pin markers at their true pinInfo positions and
labels flanking the side each pin lives on. pinInspectorLayout is pure
geometry - nearest-edge classification, per-side label stacking with a
minimum spacing and leader lines when nudged, interior pins as
dot+tooltip - driven only by pinInfo plus the measured element size, so
every part and board, present or future, works with no per-part data.
Dots are tinted by the pin's declared signal (i2c/spi/power/...).
- Clicking a pin keeps the old contract (onPinSelect -> handlePinClick), so
wires start with the same undo, colors and running-state gating.
- The two open gestures finally agree on coordinates: right-click always
passed viewport coords while touch passed canvas-local ones; the dialog is
now portaled to body in viewport space and the touch site converts.
- Keybind capture, the SD Card panel, the two-step delete, Escape and
click-outside all migrate unchanged. Mobile keeps the full-sheet layout.
Geometry covered by pin-inspector-layout.test.ts with coordinate tables
copied verbatim from the shipped parts (ESP32 two-column board, LED, an
interior-pin case).
Drag-to-front lifted boards but never parts: a component's z lives
inside .component-interactive-group, which is itself a stacking
context, so the 10+rank set on the inner wrapper was clamped to the
group's own level (1/2) while boards compete one level up as direct
children of .canvas-world. Once any board had been dragged it sat at
10+rank and no component could ever climb back over it — drag an LED
onto the Arduino and the board swallowed it, exactly as reported.
The rank now lands on the group itself (both branches: instruments and
ordinary parts), so parts and boards share ONE rank space and the last
thing dragged really is the thing on top. The inner wrapper keeps its
local 1/5 for selection order within the group.
An unseated board dropped over a component was painted underneath it
(boards z 0, components z 1) and became impossible to grab back; the
earlier blanket z bump for boards broke the opposite case, hiding LEDs
and transistors behind every board. Neither static order can win both.
The rule is now the user's own gesture: the FIRST movement of a drag
raises that item (board or part, symmetrically) to the top of a
monotonic dragged-stack, so a board dropped over an LED sits visibly on
top — and dragging the LED afterwards wins the stack right back.
Click-select alone never raises: selection must not reshuffle a scene
you arranged. Untouched items keep the static layering (components
above unseated boards, seated boards above their socket), and the rank
map is ephemeral — never saved with the project.
La queja: demasiados botones en una sola fila, y en pantallas pequenas se
solapan — medido, no impresion: a 1024px Code/Both/Circuit pisaban a
Compile/Run/Stop por 9-20px y Add pisaba el chat por 29px, con el idioma y
el usuario cortados fuera del viewport.
Tres piezas:
1. En el editor, el nav de marketing (Home/Docs/Pricing/...) sobra: ya
estas dentro, y cuesta exactamente el ancho que le falta a la toolbar.
AppHeader gana la variante editorMenu — mismo mecanismo que ya usa la
build de escritorio (VITE_DESKTOP) — que oculta el nav y pinta un menu
File/Edit junto al logo. El logo sigue llevando a inicio; idioma,
autoguardado, Share y usuario se quedan.
2. File/Edit al estilo escritorio: lo que se usa cada minuto sigue siendo
boton; lo que se usa unas veces por sesion va al menu. File: nuevo
workspace, nuevo fichero, abrir, guardar, importar, exportar, BOM,
imagen del esquema. Edit: undo/redo (con su estado real del historial),
centrar vista, zoom. Las acciones viven en cierres de cuatro
componentes distintos, asi que hay un registro id->handler
(lib/editorCommands, mismo patron de seam que registerProExamples o
registerBoardBuiltins): cada dueno registra al montar y el menu invoca
por id; un item sin dueno montado se pinta deshabilitado, que ademas es
la verdad. El registro sobrevive al remontaje StrictMode (el cleanup
viejo no borra al sucesor) y tiene test de eso.
3. La toolbar adelgaza: fuera Undo/Redo (Ctrl+Z/Y siguen), fuera los
botones inline de Import/Export y sus gemelos responsivos del More
(~70px recuperados); el More queda solo con los extras pro (firmware,
GitHub, share, grabacion). El CSS responsivo de los botones retirados
se va con ellos.
Suite en verde (2300) y build del overlay verificado desde este arbol.
Tres cambios que van juntos porque atacan la misma queja: "anado un
elemento y a veces ni veo donde se anadio".
1. Donde cae. Ya se anclaba a la esquina visible, pero la cascada que evita
que se apilen iba indexada por components.length: seguia avanzando
aunque movieras o borraras piezas, asi que las caidas se alejaban cada
vez mas de donde estabas mirando. Ahora toma el primer hueco LIBRE desde
la esquina, bajando en diagonal; si apartas la ultima, la siguiente
recupera su sitio. Extraido a utils/dropSlot con 8 tests, incluido el
caso de "la apartaron" y el tope para no salirse de la vista.
2. Que se vea. El recien anadido queda seleccionado, y la seleccion pasa de
un borde discontinuo quieto a un caminito de hormigas. El movimiento es
lo que capta el ojo en un canvas lleno; un borde fijo se pierde. Va en
un pseudo-elemento por fuera del cuerpo, sin robar clicks ni tapar el
dibujo, y se queda quieto si el sistema pide menos animacion.
3. Clicks. El izquierdo SELECCIONA y ya esta; antes abria el panel de
propiedades, o sea que no podias ni senalar una pieza sin comerte un
popup que luego habia que cerrar. Propiedades y pines pasan al click
derecho, que es donde va lo deliberado. En tactil se mantiene tocar ->
panel, que ahi no hay boton derecho.
Seam nuevo registerBoardBuiltins/getBoardBuiltins: una placa que el arbol
OSS ya dibuja (la familia Pi) puede recibir perifericos del overlay sin
registrar un ProBoardDef, que es lo que secuestraba el arte de la placa y
dejaba los cables en la esquina. El overlay lo usa para llevar los frames
del guest (cv2.imshow) al panel cableado en el canvas.
Arregla ademas el guard de connect() del bridge: comparaba readyState con
WebSocket.OPEN leido del global, asi que cuando esas constantes no estaban
`undefined === undefined` era cierto con socket a null y connect() volvia
sin abrir nada — el bridge se quedaba muerto. Ahora comprueba que el socket
exista y usa el valor numerico. Recupera los 12 tests de
multi-board-integration que esto habia roto.
El test del UART Pi->Uno pasa a comprobar el contrato vigente: por el cable
va onUartTx (el UART del header), no la consola del guest; y se anade el
caso que fija que la charla de arranque NO se filtra al vecino.
The boards array is replaced on every serial batch, so the attach effect
detached/re-attached built-in peripherals at up to 60 Hz while output
flowed; events landing inside the 500 ms re-attach window were lost.
One-shot streams (a guest display list) never recover — the repainting
SPI LCD decoders masked this for ESP32 boards.
- profile key extra_drive: optional read-only second virtio-blk so an
overlay can ship guest-side shim libraries (/dev/vdb)
- SENS <name> protocol op: canvas-fed named values (built-in sensors /
buttons) served from PiInstance.sensor_state, pushed by the frontend
via the new pi_sensor_state WS message
- DISP <b64> protocol op: guest display commands forwarded to the
frontend as 'display' events (built-in screens)
- RaspberryPi3Bridge: onDisplay / onGpioPwm callbacks + setSensorState
- SimulatorCanvas hands piFamily boards their Pi bridge in
attachBuiltins (was ESP32-only)
Como el iman de la breadboard pero para PLACAS: un componente puede declarar en
su elemento (estilo regla 6a, igual que pinInfo) que lleva un zocalo:
get boardSocket(): { anchorPin, accepts }
y una placa cuyo boardKind case con accepts, arrastrada cerca, se posa de golpe
con su pad anchorPin sobre el homonimo del zocalo. Un solo ancla basta porque
ambas rejillas comparten paso — esa es la gracia de un zocalo. Arrastrarla mas
alla de la tolerancia la suelta, sin estado que recordar.
Enganchado en los dos caminos de arrastre de placas (raton y tactil). El
overlay privado declara el zocalo sin que este repo sepa que existe.
Tres cosas que salieron al tirar del hilo de los pull-ups.
1) ESP32_ADC_PIN_MAP era la tabla del ESP32 CLASICO aplicada a toda la familia, y
fallaba de dos maneras:
- S3: sus pines ADC son GPIO1..20, ninguno esta en esa tabla, asi que la
busqueda devolvia undefined y el listener del potenciometro no llegaba a
engancharse. El mando no hacia nada.
- C3/C6: GPIO0 SI esta en la tabla clasica, como ADC2_CH1 -> canal 9. Pero en
esos chips GPIO0 es ADC1_CH0 y sus motores toman un indice de canal de ADC1
(0..4). El valor se empujaba al canal 9, fuera de rango, descartado en
silencio mientras el firmware leia el 0. Una respuesta equivocada en vez de
ninguna, que es peor.
adcPinMapFor(boardKind) devuelve la tabla del chip.
2) El ejemplo de las gafas OLED en MicroPython declaraba sus botones con Pin.IN a
secas. Van entre 3V3 y el pin, asi que sin pull-down el pin queda FLOTANDO con
el boton abierto. El propio ejemplo ya lo avisaba en un comentario ("Add
Pin.PULL_DOWN if the pin floats") — ahora lo hace. Es un fallo de hardware de
verdad, no un artefacto del emulador.
3) gallery-run-gate.audit.test.ts: EditorToolbar bloquea el Run cuando el
verificador de circuito saca errores, asi que un circuito invalido no es
cosmetico, es la diferencia entre un ejemplo que arranca y uno que parece
muerto. Y esos defectos se esconden hasta que el circuito resuelve DE PUNTA A
PUNTA: c3-button llevaba un LED de 506 mA que nadie veia porque sus cables
apuntaban a pines inexistentes.
El test reproduce la puerta del Run tal cual (mismo snapshot de peor caso,
mismo buildInputFromStore, mismo verifyCircuit, ngspice de verdad) sobre los
227 ejemplos. Encontro tres mas sin resistencia en serie —nano-button-led,
mega-led-chase y mega-serial-control, 17 LEDs en total— y ahora quedan 0.
A partir de aqui, un ejemplo nuevo con un LED colgado del GPIO salta en CI.
El canvas reenviaba la pulsacion de un pulsador cableado como
sendPinEvent(gpio, true), o sea "pulsado = ALTO". Para el idiom canonico de
Arduino — pin -> pulsador -> GND con INPUT_PULLUP, activo a nivel BAJO, que usan
13 de los 18 ejemplos con entrada de usuario — eso esta al reves: pulsar conducia
el pin a su nivel de REPOSO y soltarlo al ACTIVO. Ademas escribia directamente en
el latch de entrada del emulador por detras de connectDigitalInputsToMcu,
desincronizando la cache lastLevel de la que ese fichero se declara unico
escritor. La victima visible era esp32-doom: cuatro botones que hacian lo
contrario de lo que pulsabas.
No lo sustituyo por la polaridad opuesta, que seria la misma adivinanza al reves:
cuando el simulador resuelve entradas por el circuito (spiceDrivenInputs), el
nivel sale del propio cableado. El INPUT_PULLUP del guest se reporta ahora como
gpio_pull, estampa una resistencia de 45k al riel de 3V3, y cerrar el pulsador
cortocircuita el nodo contra la pata que tenga al otro lado. Sale bien tanto para
un boton a GND como para uno a 3V3, sin que nadie asuma nada. El atajo se queda
solo para simuladores que se salgan del modelo electrico.
Aparte, dos arreglos de cableado:
- boardPinToNumber devuelve -1 (no null) para pines de alimentacion y masa, y
la guarda comprobaba `=== null`. Asi que la pata de GND de cada boton colaba
y registraba un SEGUNDO par de listeners apuntando al pin -1.
- c3-button y pico-button-led cableaban sus pulsadores a los pines '1a' y '1b',
que NO EXISTEN: el wokwi-pushbutton expone 1.l, 2.l, 1.r y 2.r. Esos dos
cables llevaban colgando desde siempre, asi que esos botones no han
funcionado nunca. Pasan a 1.l / 2.l, como el resto de ejemplos.
Se anclaba a la esquina inferior derecha del lienzo y tapaba una parte del area
util del circuito, que es justo donde se trabaja. Quien pana y hace zoom no lo
necesitaba para orientarse, asi que se retira entero en vez de esconderlo tras
un interruptor mas.
Se van el componente y su CSS (no los usaba nadie mas) y la linea del listado de
novedades que lo anunciaba, que ya no seria cierta.
Las dos ramas habian divergido: master llevaba el modo lenguaje ESP-IDF puro
(#139) y v3.2 la ruta de compilacion IDF v5.5 para toda la familia ESP32 mas
los arreglos de venv/toolchain. Ambas tocaban espidf_compiler.py.
Los dos lados son ejes ORTOGONALES y se conservan enteros:
- use_idf5 / arduino_mode (v3.2): que arbol IDF usa el build (5.5 vs 4.4) y
si cabe Arduino-como-componente.
- pure_idf (master): el modo LENGUAJE que elige el usuario; sus ficheros son
las fuentes del componente main con su propio app_main().
Resolucion:
- _build_env acepta los tres. Un build IDF puro fuerza arduino_mode a falso:
la plantilla CMake mete el componente arduino-esp32 en cuanto existe
ARDUINO_ESP32_PATH, asi que dejarlo puesto compilaba el core de Arduino en
un build que no tiene sketch. Lo cazaron los tests de master.
- VELXIO_PURE_SKETCH solo con pure_idf, nunca con arduino_mode a falso a
secas: un target sin core arduino-esp32 sigue entregando un SKETCH al
traductor legacy y no debe tomar la rama del glob puro.
- La identidad del build-dir suma los dos tokens (|idf:N|ard:N y |lang:pure):
ningun par de esas combinaciones puede compartir un build/ configurado.
- La cadena de escritura de fuentes queda pure_idf -> arduino_mode -> legacy.
- sdkconfig: render de v3.2 (con target/use_idf5) mas el filtrado de simbolos
CONFIG_ARDUINO* de master cuando el build es puro.
test/backend/unit/test_espidf_compiler.py: los 7 tests que ya estaban rotos en
v3.2 (AttributeError: idf5_path, fixture sin actualizar desde que se anadio la
seleccion de IDF) vuelven a pasar.
Verificado: backend 293 pasan / 0 fallan (v3.2 traia 7 rotos); frontend 2268
pasan / 0 fallan en los dos shards.
registerSensorControls() lets a private build add SensorControlDef entries for
sensors it ships outside the OSS tree (e.g. the DFRobot Gravity analog family)
so they get the live slider panel; every SENSOR_CONTROLS lookup now goes
through getSensorControl(id) which falls back to the registered map. Dead code
in a pure OSS build, same contract as proBoardRegistry / registerComponentDoc.
Boards with built-in hardware (LCD on the element's own canvas, speaker,
on-board buttons/keyboard) need run-time wiring between the DOM element and
the board's simulator shim / ESP32 bridge. One generic SimulatorCanvas effect
now hands those handles to the overlay's attachBuiltins shortly after run
start and runs its cleanup on stop — no board names in the OSS tree.
Two issues from a real ESP32 7-segment clock the agent built.
Run after the agent didn't work until a page reload
---------------------------------------------------
The agent's run_simulation leaves the ESP32 board RUNNING (live QEMU
WebSocket). Esp32Bridge.connect() is a no-op while the socket is non-CLOSED,
so the user's subsequent Run click called startBoard() → connect() → did
NOTHING. And if the backend QEMU session had since died while the frontend
socket lingered (CONNECTING/OPEN/CLOSING), the user saw a dead sim that only
a reload cleared — exactly the "di Run y no funcionó; recargué y sí" report.
The Arduino/C++ QEMU path now stops a running board first (closing the WS),
waits for it to settle, then boots fresh — the MicroPython path already did
this for the same reason.
Wires painted over the 7-segment digits
----------------------------------------
The agent bridges each segment strip to its resistor from a breadboard hole
that is physically UNDER the seated display; on the flat canvas those wires
(wire layer z 35) painted over the digits (component z 1) — "casi ni se ven
los dígitos". A large-bodied display seated on a breadboard now renders
ABOVE the wire layer, so its face occludes the wires crossing it exactly as
the real part's body would (the wire passes behind it to reach the hole).
Scoped to display bodies (7segment, matrix, oled, lcd, ili9341, led-ring…)
and only when actually seated; thin parts and free-floating displays are
untouched. The pin overlay + seated-pin markers share the display's stacking
group, so they rise with it and wiring still works.

Fixes the reported breadboard wiring UX ("requerimos un vocabulario"):
Vocabulary implemented (breadboardOccupancy.ts, pure + unit-tested):
- 1 hole = 1 wire. A hole already holding a visible wire can't start a
new one — clicking it SELECTS that wire. This is the core fix: wires
running hole-to-hole across the board were impossible to select
because the pin overlays swallowed every click and silently started a
new wire (so the top horizontal rail wire was un-deletable).
- Same 5-hole strip / rail = one net. When a new wire end lands in an
occupied hole (a seated leg or another wire), it shifts to the
NEAREST FREE hole of the same group — electrically identical, the
real-world "bridge to the next hole in the row". Never crosses strips.
Two selection bugs behind the symptom:
- Click on a wire lying over the breadboard BODY now selects the wire
instead of opening the breadboard's 830-hole property dialog (that
list popping over everything was the "se sobrepone la lista de todos
los puntos" report). Guarded so the bubbled canvas click doesn't
re-toggle the fresh selection.
- Click on a hole occupied by a wire selects the wire (handlePinClick),
so wires anchored in holes are reachable at all.
Jumper colors (like a real kit — a board of identical green wires is
unreadable, "se ven todos verdes"):
- Power-rail holes mandate red (tp./bp. = +) / black (tn./bn. = −).
- Other breadboard holes get a random jumper-palette color on manual
draw; red and black are reserved for rails.
- jumperColorForId gives agent/deterministic callers a stable per-wire
color across reloads.
Tests: breadboard-occupancy.test.ts (12) — findWireAtHole (skips seating
wires, topmost wins), resolveFreeHole (same-strip shift, no cross-strip,
rail shift, passthrough), color policy (rails, palette determinism,
red/black reserved).

Running a multiplexed 4-digit 7-segment clock on ESP32/QEMU froze the
browser for minutes after Run — evaluate probes waited 40-90 s, and before
the first fixes the sim WebSocket eventually died (code 1006) with the page
never recovering. CPU-profiled on staging; four compounding per-GPIO-edge
costs, in profile order:
updateComponentState minted a new components array per edge
------------------------------------------------------------
The store setter rebuilt `components` (and one properties object) on EVERY
edge even when the state didn't change. The breadboard is direct-wired to
13 board pins, so segment toggles produced thousands of store sets per
second; every subscriber re-rendered each time, and the canvas subscription
effect (deps: [components, ...]) re-subscribed all pin listeners in a loop.
Now a no-op guard returns prevState unchanged, and breadboards are treated
as self-managed (they have no visual on/off state to echo).
CompilationConsole re-rendered every log line per editor render
----------------------------------------------------------------
The post-compile console holds hundreds of lines; each render called
Date.toLocaleTimeString per line (~0.2 ms each — it builds a fresh Intl
formatter every call). Profile: 162 s of self time in LogLine over a 337 s
window, in ~150 ms tasks. LogLine is now memoized (entries are immutable),
timestamps go through one shared Intl.DateTimeFormat, and the console
itself is React.memo'd against parent re-renders.
Per-edge full SPICE re-solves
------------------------------
PinManager requested a FULL netlist rebuild+solve on every 'mcu' edge.
Now only the edge that newly classifies a pin as MCU-output triggers the
rebuild (that's what emits the pin's V-source); steady-state updates flow
through connectMcuEdgesToService's per-pin coalesced alterSource path.
The start.ts resolve hook is trailing-throttled (33 ms) for the other
per-edge callers (RP2040, custom chips), the service's pending-edge queue
drains on a 33 ms gap timer instead of replaying back-to-back, and new
edges arriving inside the gap queue instead of soloing a solve.
STM32 / Pi reverse pin-name mappings added to connectMcuEdgesToService so
those boards keep fine-grained updates now that the full-tick storm is
gone (PA0/PC13-style and GPIO-style names never matched before).
wokwi-7segment re-rendered per segment write
---------------------------------------------
element.values now flushes at most every 8 ms per display (trailing write
guaranteed), instead of re-rendering the 32-shape SVG per edge.
Also: CLN (colon) pin support for 7-segment clock faces — wired CLN now
drives colon/colonValue in both the attachEvents path and the QEMU
onPinStateChange path; it was silently ignored, so clock colons never lit.
Verified on staging with the failing project: main-thread probes drop from
40-90 s waits (324 long tasks, 52.6 s blocked in 150 s) to 5-11 ms
(2 long tasks, 179 ms), display shows 12:00 with the colon blinking at
1 Hz from the first seconds after Run.

Extends the existing component-avoiding A* (wireAutoRoute.ts) into the full
auto-router the canvas was missing. Three pieces:
Wire avoidance with soft costs
------------------------------
Component bodies stay hard-blocked, but wires get graded costs: running
parallel on top of another wire (within an 8px corridor) is charged per px,
a perpendicular crossing costs a small fixed amount, and bends keep their
existing penalty. Crossings must stay possible — hard-blocking wires makes
dense boards unroutable and everything would degrade to the default elbow.
The compressed grid gains "corridor" coordinates 8px to each side of every
wire segment, so the router actually has a lane to run BESIDE a wire; that
is also what lays multi-wire runs out as a tidy side-by-side bus, since
each new wire routes seeing the previous ones. Wires sharing an endpoint
with the route are exempt (wires meeting on a pin must touch there), and
only wires within 120px of the route's bbox participate, keeping the grid
under the coordinate cap on dense canvases.
autoRouted: the system owns the shape until the user takes it
-------------------------------------------------------------
New Wire flag, set by pin-to-pin creation and by agent add_wire. Every
shape-editing gesture (segment drag, waypoint drag, waypoint insert — five
call sites) clears it: from that moment the wire is hand-authored and is
NEVER re-shaped, exactly where the user put it. Wires from older projects
have no flag and are treated as hand-authored.
recalculateAllWirePositions re-routes flagged wires after endpoints move
(component drag end, agent batches, mount settle — never per drag frame).
This is also what routes agent wires at all: they are created before their
elements mount and before pin coords are final, so creation-time routing
is impossible; the settle-timer recalc routes them once geometry is real.
Live routed preview
-------------------
updateWireInProgress routes start->cursor (throttled to 40ms) and the
preview renders that path, so the wire dodges components and wires AS THE
MOUSE MOVES instead of snapping into shape on the final click. Hand-guided
previews (user-placed waypoints) keep the classic path untouched.
Verified in the live app: an agent-built breadboard circuit shows 0 wire
overlap px and 0 body crossings across all wires, and a hand-started wire
aimed collinear with an existing run previews 21px beside it, overlap 0.

An ESP32 clock built by the agent stayed dark while QEMU was verifiably
emitting hundreds of GPIO edges per second (437/pin measured on the live
websocket). Reload did not help — this was not the seating race. Two
independent tracing bugs, reproduced from the real project circuit (fixture
included) and each sufficient to kill the display:
Boards added at runtime were invisible
--------------------------------------
isBoardComponent matches static id prefixes ('arduino-uno', ...), which only
covers the default board. Every board added at runtime gets a minted UUID id
— the agent's add_board always does — so traceDetailed treated the board
endpoint as an unknown component and resolved null, and SimulatorCanvas's
direct-wire subscription path skipped it entirely. Every Uno project happened
to work because they reuse the default board whose instance id IS the literal
'arduino-uno'. Both sites now consult the live boards list first, keeping
isBoardComponent as the legacy-id fallback.
Strip walking missed wires stacked on one hole
----------------------------------------------
The breadboard group walk continued the trace from every OTHER wired hole of
the strip, excluding the arrival hole by name. But two wires may legitimately
share one hole — the agent bridges strips straight into the seat hole (8 of
this circuit's 9 bridges land exactly on a resistor's own hole), which is
electrically identical to using a free hole of the strip. The name exclusion
made those junctions dead ends. Exclusion is now by incoming WIRE id, so
same-hole connections resolve; the depth bound already prevents ping-ponging
between two wires of one net.
With both fixes the exact saved circuit resolves every display pin to its
GPIO (A..DP -> 32,33,25,26,27,14,12,13; DIG1..4 -> 15,2,4,5; COM -> GND) and
the live project now shows 12:00 on the real QEMU simulation. traceDetailed
is exported for the regression test, which drives the real store with the
real circuit.

Seating is otherwise invisible — a seated pin connects to its hole through a
zero-length `bb` wire that never renders — so a user couldn't tell a part
that merely sits ON the board from one whose pins are actually connected.
This was reported after placing parts that looked seated but gave no signal
they were wired in.
SeatedPinMarkers draws a small always-on green dot (Wokwi-style) on each pin
that has a `bb` wire, derived once per render from the store's wires
(component pin = wire start). Non-interactive layer below the wire-target
hit boxes; only breadboard-seated pins light up, so board-wired builtins stay
unmarked — exactly the "seated vs connected" distinction that was missing.
The per-pin rotation math (rotate about the wrapper centre, which the overlay
layers live outside of) is extracted from PinOverlay into a shared
`rotatePinLocal`, so the dots and the wire-target boxes can never drift apart
under rotation. A test asserts rotatePinLocal agrees with calculatePinPosition
at 0/90/180/270°.

Three changes, all driven by a real project where a 4-digit 7-segment clock
was unreadable and half its parts were not actually seated.
Labels on hover only
--------------------
Eight vertical resistors at 19 px pitch rendered eight 93 px "Resistor 220 Ω"
labels on top of each other, hiding the parts and the breadboard holes; the
SPICE overlay added ~40 more `0uV` pills. Both are now revealed on hover:
hovering a part also lights up the voltages of every wire touching it.
The label is hidden with OPACITY and stays in flow. pinPositionCalculator
derives the rotation pivot from wrapper.offsetHeight, so taking it out of
flow would move the pins of every rotated component in every saved project.
Seat-on-drop
------------
The drag-time magnet only aligned the anchor pin and assumed the rest
followed, which is how parts ended up HALF-seated: some pins in holes, the
rest dead in the air. It looks mounted in a screenshot and silently breaks
the circuit. On release we now re-solve properly — nearest position where
EVERY pin is in a free hole, sliding past occupied columns — via the new
solvePlacement/seatOnDrop. Geometry comes from the element's own pinInfo,
so there is no part whitelist.
Sub-pitch translation
---------------------
solvePlacement first assigned pins to holes at half-pitch, then translates
by the centroid of the residuals before judging fit. Pinning the anchor dead
centre refused every off-lattice footprint: a diode spans 7.5 pitches, so
one leg landed 4.8 px out. Shifted 2.4 px, BOTH legs sit inside tolerance —
what bending the leads does on a real board. Measured over the catalog this
takes seatable parts from 87 to 125 of 152; diodes, transistors, regulators,
optocouplers and flip-flops are rescued with no artwork change.
Staying under SEAT_TOLERANCE (< half pitch) keeps each pin's nearest hole
unambiguous, so computeSeating resolves the same holes and the netlist is
unaffected by the small offset.
Also: refuse a placement that would put two of a part's own pins in one
strip. A column strip — and far worse, a power rail — is a single net, so
such a seating shorts the part to itself. Without it a 7-segment happily
lays its pins across a rail. And deduplicate pin names before solving:
calculatePinPosition resolves by name and returns the first match, so a
board carrying GND x5 collided with itself and was refused outright.

Every resistor variant ('resistor' + 'resistor-<value>') now lands on
the canvas rotated 90 degrees: reads better, takes less horizontal
space, and drops straight into breadboard columns. Explicit rotations
in metadata defaults are respected. The breadboard auto-vertical drag
check widens from the two-entry set to the same prefix predicate, so
preconfigured variants (resistor-330 etc.) rotate on the board too.
Parts now plug INTO the breadboard instead of using it as a junction box:
- Drag magnetism: while dragging, the part's anchor pin snaps to the
nearest hole center (9 px range, 9.6 px grid) so parts land perfectly
aligned, like Wokwi.
- Seating: every pin within 4 px of a hole gets an invisible zero-length
wire (Wire.bb) from pin to hole — the exact model Wokwi persists as
["r1:1","bb1:6t.b","",["$bb"]]. Electrically they are ordinary
wires, so the netlist builder, digital trace and SPICE need zero
changes; they are simply not rendered and not hit-testable. Seating
re-computes on every move/rotation (updateComponent), and moving the
breadboard carries its seated parts along.
- Resistors auto-rotate to vertical when dragged over a breadboard
(their 58.8 px pin span bridges the center trench rows b-f exactly).
- Seat tolerance 4 px: absorbs the worst element pin-spacing residual
(~1.6 px) while staying under half the hole pitch, so a pin is never
ambiguous between holes.
Wokwi interchange fixes that fell out of the diagram.json research:
- import maps the top-level rotate attr onto properties.rotation
(previously every rotated part imported flat) and export emits it
back as rotate instead of leaking it into attrs;
- $bb / empty-color connections import as bb seating wires and export
back as ["$bb"] entries, so parts-on-breadboard projects round-trip;
- wokwi-breadboard-half aliases to the full breadboard (hole names are
a strict superset, so every connection stays valid).
Breadboard elements now export their pure hole grids and import cleanly
without a DOM (node tests); geometry + store seating covered by
breadboard-snap.test.ts and breadboard-seating.test.ts.
Hand-aligning a dragged segment could leave two parallel runs a pixel
or two apart, joined by a tiny perpendicular step, because alignment
snapping only ever targeted OTHER wires' geometry.
- Segment and bend-point drags now also snap (6 px threshold) against
the dragged wire's own points — excluding the ones being dragged —
so a run clicks into line with its neighbour and the exact
simplification fuses them into one segment on commit.
- fuseMicroJogs: parallel runs offset by under 2 px joined by a tiny
step are aligned automatically (the run not anchored to a wire
endpoint moves; shorter run yields when both are free). Applied at
render time and in renderedToWaypoints/normalizeWireWaypoints, so
already-saved crooked wires display straight without touching data.
Three wiring quality fixes:
- Rounded corners: every bend now renders as a quadratic curve
(radius 7, clamped to half the shorter adjacent segment), with
round line caps/joins. Segment/waypoint drag previews and the
in-progress preview use the same path builder so the look is
consistent everywhere.
- Degenerate geometry cleanup at render time: the expanded polyline
is simplified (duplicates, collinear runs, U-turns) before the
path is emitted, so wires saved with junk waypoints no longer
render on top of themselves. Stored data is untouched until the
user edits the wire.
- WYSIWYG commit: finishWireCreation materialises the final-leg
elbow exactly as the live preview drew it (longer axis first) and
normalises the stored waypoints. Previously the committed wire
fell back to horizontal-first and visibly changed shape on click.
simplifyOrthogonalPath moved to wireUtils (re-exported from
wireHitDetection for existing imports); the duplicated inline
expansions in SimulatorCanvas now use the shared helper. Waypoint
dots on idle wires removed (visual noise); endpoint dots stay.
Any pushbutton (pushbutton / pushbutton-6mm) can now be driven from the
keyboard. Assign a key from the component property dialog — a keycap
control captures the next keypress (Escape cancels, modifiers alone are
rejected) — and a keycap badge next to the component label shows the
mapping on the canvas. Several buttons may share one key on purpose;
the dialog shows a hint when that happens.
At runtime a global bridge translates keydown/keyup into the same
button-press / button-release DOM events the mouse fires on the wokwi
element, so every simulation path (avr8js pin logic, SPICE-driven
inputs, the QEMU GPIO bridge, the pressed visual) behaves identically
to a mouse click. Guards: ignored while typing in inputs or the code
editor, ignored with Ctrl/Alt/Meta held, auto-repeat collapses into one
long press, and window blur releases everything so no button sticks
after Alt-Tab.
The binding is stored as the component's 'key' property, so it
round-trips through project saves and .vlx exports and is undoable like
any other property edit. Strings added to all 9 locales.
A breadboard is the physical base of a circuit — boards, components and
wires all plug into it — so it should never cover them. Pin its group at
z-index -1 (below boards z 0, components z 1/2, wires z 35), ignoring
selection. Detected by metadataId prefix 'breadboard' (breadboard,
breadboard-mini). Its own pins stay wireable wherever it's not covered.
Three UX fixes to the pin squares:
- Pins show on hover or while wiring only. The active board and the
selected component used to light every pin permanently.
- Dense components (>60 pins — breadboards) don't paint a wall of blue
on hover: squares stay invisible and light up individually under the
cursor. While a wire is in progress every square paints again since
they're all valid targets (new `wiring` prop threaded to PinOverlay).
- mousedown on a pin square stops propagation, so press-and-drag from a
pin no longer pans the canvas.
Two stacking bugs:
1. Pin overlays used a global z-index 30 while component bodies sit at
z 0-5, all in .canvas-world's single stacking context — so a covered
component's pins painted on top of whatever covered it (arduino pins
showing through a breadboard). Each component/board group is now a
zero-size positioned wrapper that forms its own stacking context
(boards z 0, components z 1, selected z 2): pins stay above their own
body but are hidden together with it. .components-area becomes
pointer-events: none so board pins/drag overlays (now trapped at z 0)
keep receiving clicks through it; component groups re-enable their own.
2. The Add Component / board picker overlays (z 1000/2000) rendered
behind the pro AI chat panel (z 8000). Both now portal to <body> at
z 9000.
Verified in-app: board drag, component drag, wire creation from board
pin to LED, covered pins hidden (0/14 leak), covering component's pins
still clickable.

The red viewport rectangle read the React `pan` prop, but the canvas
pans by mutating panRef + the .canvas-world transform directly (no
setState until pointer-up, for zero-lag dragging). So while you dragged
the canvas the rectangle sat frozen and only jumped at the end. The
minimap now also receives panRef/zoomRef and mirrors them via a
requestAnimationFrame loop that setStates only on change, so the rect
follows the canvas every frame while keeping the canvas render-free
during the gesture.
Also: boards were all drawn as one fixed 120x90 world rectangle
regardless of the actual board, misrepresenting the layout. Use the real
per-board BOARD_SIZE (now exported from BoardOnCanvas) so each footprint
is proportional. And enlarge the map 100x75 -> 160x120 (same 4:3 as the
4000x3000 world) so it's usable.
recordUpdateWire was used by the wire colour palette and the right-click menu but
never destructured from the store, so every colour-swatch click threw
'recordUpdateWire is not defined' and did nothing. tsc would have caught this, but
build:docker skips type-checking, and the only prior caller (the touch-only palette)
was never exercised. Bind it like the other record* actions. Together with the
applyNow fix this makes wire colour changes from the UI actually work.
Changing a wire's color on desktop was keyboard-only (select wire + 0-9/c/l/m/p/y)
with no visible control — the floating color palette (SelectionActionBar) only
rendered on touch devices, so desktop users had no way to discover it. Now:
- the wire SelectionActionBar (top-center, with the color palette) also shows on
desktop when a wire is selected and the sim is stopped (it is pinned top-center
so it never covers pins); component/board bars stay touch-only.
- right-clicking a wire opens a context menu with the color swatches + delete.
Keyboard shortcuts still work. Mirrors the existing board context-menu pattern.
All three bugs are rotated components whose pin geometry is computed in a
path that ignores the rotation, so pins/wire-starts land tens of pixels off
the visual pin tips. The live rotate action already recalculates correctly;
these are the paths that didn't.
#231 (context-menu 'Tap a pin to wire'): both onPinSelect handlers in
SimulatorCanvas computed the wire start as getBoundingClientRect().left +
pin.x — adding the UNROTATED pin offset to the ROTATED bounding-box corner.
On a 90-deg HC-SR04 that put the start ~70-100px off (measured). Replaced
with calculatePinPosition(id, x+6, y+6, rotation), the same rotation-aware
helper wires and the pin overlay use.
#232 (rotate -> delete -> undo): recordRemoveComponent's undo restored the
component + wires but never recalculated wire endpoints, so a rotated part's
wires kept the unrotated coords captured at delete time. Added a
requestAnimationFrame updateWirePositions(id) after restore.
#230 + #232 (pin boxes wrong after import / undo / load, 'fixes if rotated
again'): PinOverlay captured the wrapper's layout box (the rotation pivot)
once at mount. On import/undo/load the component mounts already-rotated and
its wokwi-element may not be sized on the mount tick, baking a wrong pivot
that only refreshed when rotation changed. PinOverlay now re-measures after
layout (rAF) and whenever it is about to become visible (showPins dep).
The NTC breakout's SPICE topology was inverted relative to the example
sketch's decode formula (rNtc = R_PULL * v / (5 - v)), which assumes a 10k
pull-up from VCC to OUT and the NTC from OUT to GND. The mapper had the NTC
on top (VCC->OUT) and the pull-down on the bottom, so the recovered
temperature ran backwards: dragging the slider to 100C made the sketch
print -25C. Swap the two resistors so V_OUT = 5 * Rntc / (Rntc + Rpull),
matching the sketch and the hand-built reference netlist in
spice-avr-mixed.test.ts (T=0 -> ADC 789, T=25 -> 511, T=50 -> 270).
Also replace the SensorParts linear approximation (2.5 - (t-25)*0.02) with
the same beta-model divider so the non-SPICE ADC injection decodes back to
the slider value, and drop the dead onInput path that treated the element's
value as a raw ADC count.
Reset now restores interactive sensors (temperature/lux/gas sliders) to
their configured defaults: resetBoard re-dispatches each sensor's default
into the running sim and bumps sensorResetNonce so the open
SensorControlPanel remounts and the slider snaps back. Previously a restart
left the NTC frozen at the last dragged temperature.
Updated the examples netlist snapshot for the swapped NTC cards.
The canvas had two independent window keydown listeners. The wire handler
removed the selected wire and returned, but that return cannot stop the
separate component/board handler, which fell into 'else if (activeBoardId)'
and popped the board-removal confirmation. activeBoardId is not a visual
selection -- it is just the board whose code is open in the editor, so it is
effectively always set. Pressing Delete to remove a wire (or after deleting a
component) therefore always asked to remove the board.
Remove the keyboard board-delete branch entirely: Delete/Backspace now only
removes the selected component. Board removal stays on its deliberate paths
(right-click Remove board, touch pin-picker delete). Also add the text-field
guard (input/textarea/select/contenteditable) to the wire handler so Backspace
while typing in the AI chat no longer deletes a selected wire.
The Pico W emulation runs in THIS browser tab via requestAnimationFrame.
Opening the gateway with target=_blank / window.open backgrounds the
emulation tab; the browser then pauses its rAF, the simulated chip
freezes, and the gateway can no longer reach the server on it — the
request times out (502) and toggles do nothing.
Render the served page in a same-tab iframe panel (openDeviceGateway) for
the Pico W so the emulation stays in the foreground and keeps answering.
The ESP32 is unchanged (its server runs in QEMU on the backend, immune to
tab visibility), so it keeps opening in a new tab.
Also: the async-led page now shows the LED state (the board's onboard LED
isn't drawn on the canvas) so the toggle has visible feedback.
- SerialMonitor linkifies http://10.13.37.x (the Pico W subnet) the same
way it already does http://192.168.4.x for the ESP32, turning the
sketch's printed URL into an 'Open IoT Gateway' link.
- SimulatorCanvas shows the clickable WiFi badge for the Pico W too
(normalizing its 'started' status, which carries the fixed IP, to
got_ip so it reuses the ESP32 badge styling + launcher).
- async-led and servo-web examples print a clickable http://<ip>/ line
so the gateway link appears (relay-web-server already did).
Gated e2e (CYW43_GATEWAY_E2E=1) drives the real emulator + a running
backend and asserts the served page comes back through /api/gateway.
Board-less digital circuits (logic gates + switches + LEDs) run today as ngspice
analog B-sources, which is fragile for deep logic: a 4-bit ripple adder re-solves
but never lights its result LEDs live. This adds an event-driven digital motor
that reuses the multichip-bus settle kernel, so the same engine that boots a Z80
over a chip bus evaluates a gate network exactly and instantly.
Phases 0-2 (project/digital-gate-engine/), all behind ?digitalgates=on (default
OFF — flag off is byte-for-byte the old behaviour):
- digitalGateEngine.ts: buildDigitalNetwork(components, wires) does union-find
over the wires (merging pass-through resistors), identifies the rail/gnd from
the signal-generator, registers drivers (rail STRONG-1, gnd 0, pull resistors
PULL, slide-switch as a pass-gate) and event-driven gates (reusing the
LogicGateParts boolean semantics), settles on busKernel, and exposes
setSwitch / readLed / netOf. Tolerant of both the raw example `type` and the
store `metadataId`. Returns {ok:false} for any non-primitive, so mixed/analog
circuits stay entirely on ngspice.
- digitalGateController.ts + a SimulatorCanvas useEffect: when the flag is on and
the circuit is all-digital, rebuild from the store on switch-toggle / load
(rAF-coalesced) and paint the wokwi-led DOM. CircuitSimulationService.tick()
skips the SPICE solve for all-digital circuits when the flag is on, so the two
motors never fight over the LEDs.
Tests: digitalgate-kernel (22 — single gates -> half/full adder -> 4-bit
adder/subtractor -> exhaustive ADD 256 -> mux/decoder/comparator/parity/
multiplier) and digitalgate-engine-examples (6 — the real gallery data for
and/or/xor/not + the full adder/subtractor). Verified live: ?digitalgates=on
lights the adder's result LEDs that the SPICE path leaves dark. Full suite
2117 pass / 5 pre-existing unrelated fails.

Reported: on a running circuit, clicking a pushbutton SELECTED the wire under it
instead of pressing the button — and you could still move wires / pick pins to
make connections during a run.
Root cause: component dragging was already locked during a run, but the
canvas-level onClick (wire selection via findWireNearPoint) wasn't — so a click
on a button bubbled to the canvas and selected the wire. The button press itself
fired (shadow DOM), but the wire-select made it feel broken.
Gate every EDIT interaction on the existing interactionRunning predicate while
keeping part interaction (buttons/switches/pots) and pan/zoom:
- canvas onClick wire-selection + onDoubleClick waypoint-insert
- wire segment / waypoint drag handles (mouse + touch)
- pin-click wire creation
- touch tap wire-selection
- hide the PinOverlay (was gated on !running, so board-less runs still showed
clickable pins) and skip wire-hover highlighting while running
- clear any wire/component selection when a run starts so leftover handles don't
linger over the live circuit
Component drag + property dialog were already gated on interactionRunning; this
extends the same 'freeze to edit, run to interact' model to wires and pins.

Phase 2 of the run-system/UX work.
- BoardInstance gains an optional user ; boardDisplayName(board) resolver
(name || kind label) routes every INSTANCE-label surface: file-explorer
section header, compile console (EditorToolbar), canvas selector/tooltip/
context-menu, Serial Monitor tabs, Oscilloscope board picker, Board Options
subtitle. Board/component pickers keep the KIND label (they pick new boards).
- Inline rename on board AND chip section headers (double-click the name, or a
hover pencil button). Board -> updateBoard(id,{name}); chip -> chipName in
properties. Enter commits, Escape cancels (cancel-flag ref guards the
unmount-fires-onBlur footgun), empty clears to the kind / 'Custom Chip'.
- FileTabs shows an owner badge naming the board/chip whose files are shown
(resolved as a selector so it doesn't re-render on every sim pin toggle).
- CustomChipDialog no longer clobbers a user-given chipName: chip.json's name
only seeds the blank defaults (My Chip / Custom Chip); loading an example
relabels explicitly.
- Persistence: board name round-trips via projectPayload (+ dirty hash),
vlxFile, ProjectByIdPage load + loadProjectState; chipName rides components_json.
- Drive-by: fixed a pre-existing rules-of-hooks violation in BoardOptionsModal
(early return before a useCallback).
Reviewed by a 3-agent adversarial pass (completeness / persistence / correctness);
all major findings folded in.
