M0 (docs/FEASIBILITY.md, verified against esp-emulator wasm v0.51.0): - GPIO outputs observable via gpio_state(); gpio_set_input() drives pads and raises guest interrupts (button-class peripherals work) - LEDC PWM and RMT waveforms are NOT visible in the pad registers; duty is readable from LEDC registers and WS2812 frames decode from RMT channel RAM (per-chip MMIO map in peris/mmio/) - Node probe + ESP-IDF test firmware (gpio/ledc/rmt three-phase loop) M1 peripherals framework: - esp-emu-peris.html entry (stock layout + Peripherals/Debug tabs), peris/worker.js (stock worker clone + per-batch pin sampling hooks) - device plugin API v1 (docs/DEVICE-API.md) with manifest registry: add a peripheral = one module + one manifest line - devices: led, button, touch-button, toggle-switch; wiring config import/export + localStorage autosave; pin-conflict reporting - serve.py merged dev server, sync_www.py publisher (www only gains files, stock ones untouched), xterm vendored locally (no CDN) - tests/m1_smoke.mjs integration smoke (config/LED state/button ISR/ toggle/conflict/unknown-type) - all green
