Integrate compatible observer board, preset, WebConfig, display, CI, and policy updates. Preserve the checkout's newer MQTT binary preferences and WiFi bridge runtime where the forked implementations conflict. Keep ThinkNode observer networking WiFi-based until the Ethernet transport is wired into that runtime.
Bind Companion replies to request transports, make dual-CDC USB sessions nonblocking and reconnect-safe, and harden nRF52 watchdog/OTA storage paths. Fix T096 button debounce, display wake, sleep races, and the compact message layout; add exact WisBlock OTA profiles plus expanded native/static/HIL documentation.
The real Arduino.h includes stdlib.h, so ConfigSerializer.cpp reaches atoi,
atol and atof through it and compiles on device. The mock supplied only
cstdint, cmath and Stream.h, leaving those undeclared — and since the native
env compiles ConfigSerializer.cpp into every suite via build_src_filter, all
21 suites errored rather than just its own.
Fixing the mock keeps src/ identical to upstream and covers any other source
relying on the same transitive include.
pio test -e native: 297 test cases, 297 succeeded.
Switch ESP32-S3 KISS modem environments to HWCDC and move outbound KISS writes to a non-blocking queued frame path so loop() and TX completion keep progressing when the host reads slowly. Add native backpressure regression tests and correct the native_kiss_modem test filter so this suite runs directly with pio test.
