Persist Companion TX preferences per contact and channel. Default repeater,
room, and sensor replies to both active TX profiles, with a reply-only force
option for an RX-only secondary profile. Track both reply copies before a
temporary-radio handoff and account for OTA copies under queue backpressure.
Add bridge/crossover filter modes and the third built-in wardriving filter,
plus compact filter CLI syntax, documentation, and CI coverage.
Fix quoted target names being interpreted as slot/key selectors, partial
recovery of invalid saved reply settings, filter suspension during tempradio2,
and unnecessary packet allocation while OTA traffic is throttled.
Validation: 1,477 native tests, 52 Python integration tests, 29 filter UI tests,
and five firmware builds covering ESP32, nRF52, and STM32 passed.
Integrate ExpressLRS TX module support and its stacked ESP32 heap changes.
Use the approved Linkflow calibration (17-30 dBm), preserve the PA drive
and output path after radio recovery, and keep LoRa OTA enabled.
Preserve stored ACLs and filters on allocation failure, release owned
client/filter buffers, service heap OTA contexts on Companions, release
self-serving workspaces after TempRadio, and reset staged-resume state
when a context is released. Keep manual staging and active operations
alive. Account for all moved allocations in the runtime RAM gate.
Validation: 1,393 native cases; radio-power, heap-context, ACL persistence,
shared-queue transfer, display/inbox, radio receive, and memory regressions.
Firmware builds passed for Linkflow, Heltec V2 Companion, T-Beam MQTT
repeater, Heltec V4 R8 MQTT repeater, RAK4631 repeater, and Indicator Full.
Physical verification awaits access to the currently offline lab Pi.
Move OTA_HEAP_CONTEXT from two hand-edited envs to a pre-script gated on
build.mcu == "esp32", so every classic ESP32 image gets it and none can drift.
S2/S3/C-series and nRF52 keep the .bss singleton: they have no equivalent
static-DRAM ceiling, so there a guaranteed-present workspace is the better
trade for what is ultimately a recovery path. It has to be a build flag rather
than a header default, because OTA_HEAP_CONTEXT must hold the same value in
every translation unit that sees OtaContext.h - OtaContext.cpp included - and a
header test on CONFIG_IDF_TARGET_ESP32 would depend on include order relative
to sdkconfig.h. The script defers to OTA_SHARED_COMPANION_QUEUE where a Full
Companion recipe already owns the storage.
Fix a gap this exposes in the roles that now use it. Only CLI entry points
acquire the context, so once it was released, a repeater with the temporary
radio profile up would no longer serve or announce its own firmware - LoRa OTA
would look enabled and silently do nothing. ota_service_temp_radio_context()
holds the workspace for exactly the temp-radio window and hands it back
outside it, which is where the saving was coming from anyway. Wired into the
repeater, room server and sensor loops; the Companion keeps its own
acquire-on-host-demand policy, since its context is borrowed from the offline
message queue and must not be taken speculatively.

Add durable TempRadio, ACL, clock, bridge, GPS/I2C, USB logging, and Indicator recovery safeguards together with expanded automation, build/profile contracts, release metadata, and the hardware validation ledger.
Add selectable shared ESP-NOW channels, raw/wrapped bridge compatibility, and bounded fragmentation for maximum-size packets.\n\nGive ESP32 Full profiles WiFi coexistence, stabilize WebConfig and USB terminal lifecycles, and keep disabled bridges stopped during observer updates.\n\nUpdate generated UI, firmware selection, documentation, and regression coverage.
