Remediation

What is left to close the current console (v3): the known bugs, each with how its fix is proven on the board. With these fixes the console becomes v3.1, still on the ESP32-S3. Studies for new consoles are under Next Steps.

Area	What is open
Audio	PDM carrier hiss: R38 RC values, I2S amplifier on the respin, default volume
Emulators	DOOM memory leak, frameskip 0 on the light cores
Hardware	respin backlog (R37, silkscreen on J3 and the speaker pads) and the open IP5306 no-battery claim
Battery Indicator	battery icon in the launcher's top-right corner: divider rework to GPIO16, ADC driver, launcher only
Wi-Fi	radio almost deaf (RSSI about −90 dBm, 1 MB uploads time out): the antenna sits over the inner GND/+3V3 planes, 15 mm inside the edge; top priority on the respin
