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)
- Register a minimal PartSimulationRegistry handler that forwards slider
values via emitPropertyChange so the netlist memo invalidates
- Switch the photodiode lux control from "range" to "number" so the
static ComponentPropertyDialog renders an editable input

- Changed JSX declarations to use 'velxio-' prefix for various components.
- Updated component overrides to replace 'wokwi-' with 'velxio-' for logic gates and other components.

- Create `waveformStats.ts` to provide statistical functions for time-domain waveform analysis.
- Implement `serial-batching.test.ts` to verify the behavior of `createSerialBatcher`, ensuring it coalesces multiple appends into a single flush, preserves byte order, and groups by board.
- Create `spice-rectifier-integration.test.ts` to test the end-to-end functionality of the Half-Wave Rectifier example, covering the entire simulation pipeline from input building to circuit solving.
- Add `spice-rectifier-live-repro.test.ts` to reproduce a live-app failure scenario, tracing through each layer of the simulation to identify potential failure points.

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)
