Recheck cached immutable paths before resetting the live table after raw I/O failure. Keep accepted RAM mutations, current jobs and save deadlines when reads recover; stronger source or publication uncertainty still forces full recovery. Use the existing recovery byte and a fixed scratch buffer, with no cache allocation or eviction.
Cover full-cache transient recovery, persistent I/O and checksum failures, nRF unread-scope restoration, active ESP jobs, real uncertain publication and unchanged lazy deadlines with sanitizer tests and restored-reset negative controls.
Do not classify legacy or page-name stat errors as unread payloads. Keep candidate contact files unchanged, retry source selection, and use bounded volatile operation if authority remains unknown. Cover legacy absence, downgrade leftovers, cleanup-time metadata recovery and persistent faults with actual-source sanitizer tests and restored-bug negative controls.
Verify fallback namespace moves before accepting publication or rollback. Reload readable contact images at a safe host boundary, discard only unreadable contact data after bounded retries, and permit volatile operation when storage cannot recover. Preserve unrelated stores and fail explicit durability requests truthfully.
Keep existing flash, RAM, OTA and capability limits by streaming nRF52 preferences through the validated wire table and sharing identical contact deadline resets. Add fault-injection, sanitizer, legacy-image parity and CLI lifecycle regressions.
Verify public images after every rename attempt, expose publication outcomes, and use an independent CRC32C fingerprint so valid IEEE-CRC-tailed images cannot mask a stale target. Preserve persistent formats and reject directories for empty images.
Reconcile uncertain migration journals before choosing filesystem authority. Preserve retained contact snapshots when page publication is unconfirmed without clearing dirty state or acknowledging the new page generation.
Add readback, rename, CRC-tail, migration reboot/quarantine, and snapshot eviction regressions. Keep complete RAK Full Companion within the unchanged OTA ceiling through equivalent code compaction, with no feature or validation cuts.
Run DHCP and renewal in a cooperative worker, bound socket commands, and retain SPI ownership until cleanup is safe. Preserve framing deadlines, response ownership and whole-frame replay, including pending-ACK queue pinning.
Budget the worker additively and retain all OTA names with an exact-checked Full-only compact index. Add full-driver, sanitizer, queue, shutdown, storage and memory regression coverage.
Let the mesh timed OTA retry guard own byte-identical requests instead of the permanent bridge FIFO. Bind bridge ingress to its primary profile generation and preserve UART reflection/liveness protections. Verified a LoRa to ESP-NOW to LoRa update with outage recovery and install.
Delay automatic GPS-free NodeInfo until a quiet TX gap, invalidate stale metadata after durable node renames, and refresh the profile when same-tuple publication releases its busy guard. Cover the real Companion methods and document the behavior.
Integrate upstream 1.18.0, delayed direct ACK forwarding, zero-scope routing, Waveshare LR1121 and dynamic WiFi variants. Preserve fork chemistry-aware power management and bounded multi-interface UI; retain retry/dedup safety while adding upstream ACK delay. Qualify LR1121 band power and HP-only Morse handling with native regressions.
Preserve observer discovery when forwarding is disabled while honoring hidden-node settings. Keep GPS power ownership paired and incorporate upstream GPS diagnostics.
Preserve Reader streaming during Morse timing and block synchronous inflate/progress interleaving. Fail closed on uncertain port ownership and enforce application-only DFU packages before querying USB. Cover the guards in CI and clarify experimental benchmark scope.
Use a 960-byte constant-time Ed25519 base table, compact hash/scalar code and unused-library trims while retaining Reader, BLE P-256 and the 8 KiB stack. RAK4631 Full saves 57,496 flash bytes and 3,152 static RAM bytes versus preview3.
Support complete chapters and verse ranges with bounded app continuation replies and cooperative terminal output. Use nonblocking TCP writes under reader backpressure. Add scalar/signature comparisons and a linked ARM crypto/stack CI gate.
Validated clean RAK4631, T1000-E, T096 and V4 Full builds, host regressions, and physical RAK chapter/reconnect and signing comparisons. Physical signing averages 35.9 ms versus 14.4 ms with the original table.
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.
Share one bounded WiFi outage and recovery schedule across MQTT, automatic NTP, Companion station ownership and WebConfig. Preserve enabled settings and foreground access while allowing normal sleep after confirmed physical shutdown.
Honor failed SDK client stops before handing off WiFi, protect clean teardown and reconfiguration, and retry transient ESP-NOW channel restoration without repeated disconnects. Add production-method, SDK failure and real sleep regressions to CI.
Validation: native MQTT/NTP/clock/reconnect suites; production power and wrapper failure tests; browser, room HTTP, OTA and combined bridge regressions; Full Heltec V4 repeater, room and companion builds with capability, flash and linked-memory checks.
