Raw LoRa packets to and from a host over the USB/console serial port, plus
upstream's SetHardware extensions (identity, crypto, radio config, stats).
- app/KissModem.cpp/h: upstream text, ZephCore changes fenced: an LBT
refusal returns to CSMA until the wait-clear bound; a TX times out only
once the radio has concluded (as Dispatcher::loop); SetRadio outside the
ZC_RADIO_* ranges is refused; msUntilNextTx() for the event loop.
- src/main_kiss_modem.cpp: event-driven composition root; runs the radio
maintenance the Dispatcher would. Identity in /lfs/repeater/_main.id.
- adapters/transport/ZephyrUartStream: Arduino Stream over IRQ RX/TX rings.
- boards/common/kiss_modem.conf: role, BT off, console driver off.
- LoRaRadio::getCurrentRSSI(), Print::availableForWrite().
- UI mesh-action stubs for every non-companion role.
Tested on 2x XIAO ESP32-C3 + Wio-SX1262 at 869.423 MHz SF7/62.5/CR5.
Built for xiao_esp32c3, rak4631, lora_e5_mini; host tests pass.

- boot_info: label the ESP32 reset reasons Zephyr's hwinfo driver maps to 0
(USB-Serial-JTAG/JTAG reset -> DEBUG, power glitch -> BROWNOUT, CPU lockup,
eFuse -> HARDWARE); get pwrmgt.bootreason no longer says Unknown after a flash
- mqtt: the uplink credentials struct moves to adapters/mqtt/uplink_creds.h,
so the adapter no longer includes an app header (layout unchanged: the
struct is persisted raw)
- gps: one off-levels routine for standby/off and System OFF; the sleep line
stays asserted in standby and drops at System OFF, as upstream's
sleep_gps/stop_gps/powerOff; System OFF now asserts reset before cutting
GPS_EN
- doom: sprites solid with a one-pixel black halo, boss drawn 1.5x on the
floor; the L2 boss was invisible from the spawn on 1-bit panels
DESIGN.md is the reconciled high-level design after the 2026-09 restructure:
system context, roles, build-time composition, layers and dependency rules
(with the known exceptions), threading and event loop, end-to-end flows,
cross-cutting concerns and the upstream alignment policy. docs/adr/ holds the
nine decision records (ESP32 boot layout, S3 native USB, overlay precedence,
BLE privacy, Zephyr main pin, SX126x duty cycle and RX-busy gating, adaptive
contention window, storage backend, WiFi companion boards).
ARCHITECTURE.md stays the detailed component reference and links both.
