agessaman 612c52132c merge: upstream/dev into observer-firmware-dev (2026-07-30, db232808)
Absorbs 106 upstream commits. Seven files conflicted; the substantive one
was upstream's new JSON ConfigSerializer (PR #2982), which replaces the
binary /com_prefs layout with /prefs.json and makes NodePrefs a
ConfigSerializer subclass.

Prefs migration
- Adopt upstream's ConfigSerializer. writeCommonPrefsImage() and its
  documented offsets (0-294) are deleted, along with the now-unreachable
  saveCommonPrefsImageAtomically()/CommonPrefsFileStore atomic rename path.
- Load order is /prefs.json, then /com_prefs, then /node_prefs. Upstream
  dropped the /node_prefs fallback; it is restored here so devices that
  never advanced past that filename keep their config.
- Legacy files are never removed, so migration cannot destroy its own
  source and a deferred or failed save simply retries next boot.
- /com_prefs is treated as a format migration only, not an "upgrade", so
  it does not trip the bridge.source tx->rx flip on existing nodes.
- The MQTTPrefsAtomicStore legacy gate is retained: the observer tail
  recovered from an old-format file still commits to /mqtt_prefs before
  /prefs.json is written.
- MQTTPrefs and /mqtt_prefs are untouched; savePrefs keeps its save_mqtt
  parameter and now returns upstream's bool.

Fixes to upstream code
- RadioPrefs::structure() bound both "rxgain" and "fem_rxgain" to
  rx_boosted_gain, so radio_fem_rxgain was never persisted. Bound to the
  correct field.
- discovery_mod_timestamp was dropped from structure(); it gates
  'since'-filtered DISCOVER replies and is set on every config change, so
  losing it would silently stop discovery responses after a reboot. Added
  as "disc_mod".

Merge artifacts repaired
- Restored bblanchon/ArduinoJson to the native test env; a clean but wrong
  auto-merge at the lib_deps block boundary dropped it and broke all 19
  host test suites.
- Migrated the fork's WebConfig UITask screens off the removed
  DisplayDriver::Color enum to upstream's UIColor element types.
- Removed duplicate getCADEnabled() definitions in companion MyMesh.cpp
  and simple_sensor SensorMesh.cpp that both sides had added.
- Dropped memset(&_prefs, 0, ...) in the four example meshes; NodePrefs now
  has a vtable. guard gains an initializer that memset used to provide.

Other resolutions
- simple_room_server keeps both the fork's discover.* commands and
  upstream's new room.post.
- docs/payloads.md taken from upstream, undoing content earlier merges had
  reverted (Control data section, split login tables).

Verified: 273/273 host tests pass across native and native_kiss_modem;
Heltec v3 repeater, repeater_observer_mqtt, room_server_observer_mqtt,
sensor, and companion_radio_ble all build clean.

Host unit tests

Fast, hardware-free unit tests for the fork's pure logic, run on the host with GoogleTest via PlatformIO's native environment. They cover the extractable observer/WebConfig logic (validation, preset table, topic templates, key parsing) — the parts that don't depend on the ESP32, radio, or network stack. Integration behavior (AsyncTCP transport, WiFi/MQTT, SoftAP) is exercised separately; see "Local testing without hardware" in MQTT_IMPLEMENTATION.md.

Running

pio test -e native                      # all suites
pio test -e native -f test_webconfig_keys   # a single suite

A green [PASSED] per suite means GoogleTest returned 0 (all assertions passed). PlatformIO's "0 test cases" line is just its Unity-style counter and does not reflect the GoogleTest count — run the built binary directly (.pio/build/native/program) to see the per-assertion breakdown.

Suites

Suite Source under test Covers
test_mqtt_presets src/helpers/MQTTPresets.h preset lookup; table integrity (unique names, non-empty URLs, JWT-audience invariant, names fit the slot buffer); mqttPresetNeedsSlotCredentials; slot-count constants

Conventions (and how to add a suite)

  • Each test/test_<name>/ directory builds into its own GoogleTest program and must define its own main() (::testing::InitGoogleTest + RUN_ALL_TESTS).
  • Tests are host-only: include only pure headers. Arduino/crypto stubs live in test/mocks/ (on the include path via -I test/mocks).
  • Firmware headers are included from src (via -I src, e.g. #include "helpers/MQTTPresets.h"). Some are guarded or ESP-flavored, so a suite may need shims before the include — e.g. test_mqtt_presets does #define WITH_MQTT_BRIDGE 1 (the preset table is behind that flag) and #define PROGMEM (the embedded CA-cert strings are PROGMEM-qualified).
  • To add a suite: create test/test_<name>/test_<name>.cpp with a main(), and add any host-only source it links to the native env's build_src_filter in platformio.ini (header-only code needs no source entry). No other wiring.
  • Keep logic testable by extracting pure functions into headers (as MQTTObserverValidation.h / WebConfigKeys.h / MQTTTopicTemplate.h do) and having the firmware call the same functions.
