Port Meshtext settings to verified atomic nRF52 storage and use the existing radio RNG and hardware entropy. Keep the ExtraFS boundary, GPS, contacts, channel count and 8 KiB stack unchanged; omit unused library data to fit the image. Require linked codec and Companion transport evidence and build the real RAK Full profile in CI. Add configuration and storage-failure regression coverage.
Extend the cooperative contact transaction to uncached ESP32 storage,
including the PSRAM policy used by the XIAO and V4. Preserve owned contact
copies, the 152-byte disk format, revision cancellation and synchronous
durability operations. Keep contact capacities unchanged.
Avoid SDK error logs when optional blob or transaction cleanup files are
absent, while preserving metadata and deletion failure handling.
Validate cached ESP/nRF and uncached PSRAM paths under ASan/UBSan,
including bounded writes, mutation cancellation, faults, recovery and
reboot readback. Update the existing uncached production fixture.
Recover usable ESP32 preferences and channels before permitting replacement; keep identity and ACL persistence transactional and complete.
Preserve MQTT commit boundaries, restore OTA identity and policy after deferred allocation, retain radio gain retries, and reject invalid flood limits. Add production-path fault regressions and CI coverage.
Keep each deferred OTA response tied to the request's radio profile and generation. Separate requests from different radio sessions, discard stale queued responses, and retain the existing companion and infrastructure reply policies.
Reject staged captures with invalid file framing before adopting their state. Recover fixed internal-flash trailer bytes after interrupted checkpoints and handle small ESP32 delta trailers that share metadata sectors. Fail closed when install preflight cannot read a valid header, so hardware and automatic-update policy checks cannot be skipped.
Replace Companion preferences through verified file transactions and quarantine writes after incomplete loads on all platforms. Initialize serializer runtime fields before preferences snapshots copy them.
Add production-code fault regressions to CI for deferred routing, store recovery, install preflight, and preferences persistence. Validation: 1,510 native tests, 60 host checks, and six firmware targets across ESP32, nRF52, STM32, and RP2040.
Reject radio changes when receive mode cannot resume and restore the previous physical profile and power policy. Preserve selected folder OTA captures across disconnects and recoverable host I/O failures, while keeping corruption failures distinct. Validate OTA staging input before arithmetic or buffer writes and revoke published data before edits.
Commit companion channels through verified file replacement on ESP32, RP2040, and STM32, and quarantine incomplete startup reads. Recheck the last management connection during delayed wireless changes and prevent conflicting Bluetooth shutdowns. Detect complete OTA implementation sources rather than the shared inflater when configuring release builds.
Add fault-injection regressions and CI coverage for these paths, and document folder capture reconnect behavior.
Validation: 1,510 native tests; 55 host integration checks; build profile regressions; ESP32, nRF52, STM32, and RP2040 firmware builds.
