Fix the STM32 flash overflows and fleet fixture compile failure from
https://github.com/mikecarper/MeshCore/actions/runs/40241742182.
Fold already-unsupported RX control paths only for the integrated STM32WL
wrapper. Preserve RXPS-off validation, persistence, pending application and
rollback. External radios retain their supported controls.
Use measured GCC 14 code sharing in the four small STM32 USB Companion
recipes. Keep firmware features, contact/channel capacities, filesystem
boundaries and flash/RAM admission checks unchanged.
Refresh downstream host fixtures for saved radio intent, deferred service
restarts, WebConfig ownership, RX recovery and color tint state. Retain or
strengthen behavior checks rather than skipping failing coverage.
Validation: canonical RAK3x72, Wio Mini, Wio Dev and Tiny Relay USB Companion
packages and Mini Repeater build passed at release-version length. All
post-failure host checks, compact arithmetic/float checks, build-profile and
real PlatformIO recipe/path/RAM-policy checks passed locally.
Replace obsolete reader-timeout and message-thread source assertions with
compiled regressions for bookmark saving across battery/USB transitions and
newest-visible message summaries in History, Pending, and Unread modes.
Extend the MQTT sleep harness with dual-radio state and verify both blockers
release when disabled. All 19 post-native verification groups pass on Linux,
including the complete UI and browser runtime suites.
Use measured text rows for companion and repeater layouts, retain the V4 6px footer, and add overlap and navigation regressions. Correct the MQTT logging sleep documentation contract test.
