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.
Add opt-in bounded chat history, persist explicit room ACL roles, enforce full-key bans and per-user quotas, and provide versioned information-board reads plus an ESP32 local room page. Preserve stored evidence on faults and withhold room delivery acknowledgments when a Companion cannot retain the message.
Exercise production handlers and filesystem fault recovery, pinned official-app JavaScript, real Chromium interactions, and representative ESP32, nRF52, RP2040 and STM32 builds. Add regression suites and bounded browser-workspace RAM reservations to CI.
Reject truncated anonymous reply paths and advert metadata before copying,
while preserving timestamp-only empty-password logins. Limit room posting to
read-write/admin ACL roles, retain inbox frames until the requesting transport
accepts them, and lock raw LittleFS traversal against concurrent writes.
Separate ISR event generations from main-loop radio state. Confirm RX/TX IRQs,
detach concrete wrapper callbacks safely, and discard inconsistent LR2021 FIFO
snapshots before rearming. Preserve bridge RX frames through packet-pool
exhaustion and bound ESP-NOW retries and missing-callback recovery. Screen RTC
register layouts without losing DS1307 startup, and ignore poisoned future
contact timestamps during clock bootstrap.
Keep the nRF52 loop stack at 8 KiB while reducing the OTA listing call chain
from 7,832 to 6,056 static bytes. Retain all target names through lossless Full
Companion compression and the canonical size optimizer. Preserve constrained
STM32 filesystems and bind corrected ESP32 UART/OLED budgets to source size
assertions. Document the separately measured preexisting W12 package limits.
Adapted for this branch from meshcore-dev/MeshCore PRs #3521, #3340, #3362,
#2062, #3503, #3038, #3534, #3544 and #3512.
Validation: 1,829 native tests; sanitized parser, inbox, LittleFS, ACL, clock,
RTC, IRQ/FIFO and bridge fault tests; 332 additional Companion cases; real
RAK4631 Full and both repeater profiles, G2 Full/standard, V3 Full and both
constrained STM32 release recipes. Radio-family compile coverage continues
separately; W12 full/portable package guards remain enforced.
Specialize repeater ACL session state, compact recent and flood records, stream Merkle proofs, and release cold OTA buffers safely. Preserve saved formats, stack sizes, table capacities, and OTA source limits. Account for lazy buffers when active and add compatibility, ARM alignment, allocation failure, and queued-response tests.
Validated six representative board/role builds, 1736 native test cases, sanitizer fixtures, and strict documentation. Document the preexisting Wio-E5 Mini flash overflow separately.
Keep Full sensors, UART2, adaptive OTA storage and the 8 KiB loop stack. Arbitrate shared SPI and OTA workspace ownership, move network waits into a worker, and use bounded queued TCP operations. Add reproducible test configs, RAM checks and regression coverage. Validated the Full build, UF2 layout and 29 sanitizer runtime scenarios.
Use a bounded uzlib-derived block encoder with the existing strict tinf decoder, qualify infrastructure roles, budget temporary RAM, and cache running-image metadata. Add self-serve CLI and policy, USB host-loss sleep grace, hardware test harnesses, regression tests, and CI coverage.
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.
