Automatically split longer signed envelopes into two bounded group-data packets, reserve both before queueing, and roll back exact packet copies and retries on admission failure. Collect fragments in either order with a fixed deadline and verify the complete command before durable replay reservation and dispatch.
Raise whole-fleet protocol capacity to 230 bytes, preserve target-specific budgets and radio acknowledgement barriers, and reject rule-token and USB rescue-line truncation. Document existing app input limits and add real-signature, sanitizer, queue failure, timeout, replay, and compact-board regressions.
Enroll a private channel and publisher public key on repeaters and room servers. Local Companion fleet sends sign targeted or whole-fleet commands, with expiry, durable replay protection, and a restricted command allowlist. Preserve exact transmitted-reply barriers for secondary-radio changes, bound validation and replies, and qualify crypto, persistence, transport scope, role permissions, and compact-profile exclusions with regression tests.
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.
Starting or restarting MQTT during browser OTA could remove the active AP by forcing STA mode. Defer shared MQTT startup and recovery, and Companion WiFi startup, pending credential reloads and saved-SSID retries, until the live SDK AP releases the driver. Preserve the setup owner's deliberate credential handoff and cooperative stop acknowledgement.
Validated 91 source host tests, including 20 new AP ownership cases and nine reverted controls under ASan/UBSan. Hardware and firmware build qualification remain separate; the Arduino mode snapshot is not atomic.
Protect standard access points from the shared ESP-IDF LR flag, defer incompatible raw ESP-NOW starts, and select RAM storage before LR writes. Track successful LR owners so setup and OTA access points reject a conflicting running transport before changing WiFi.
Run actual production policies, transport lifecycle methods, and WebConfig teardown branches against a shared-LR SDK model with runtime negative controls; include the regression in unit CI.
Arduino-ESP32 2.0.17 UpdateClass::begin() clears _target_md5 before
initializing the digest builder (Updater.cpp:123-126). The installed pinned
framework package is 3.20017.241212+sha.dcc1105b. Setting the multipart
digest before begin therefore skipped the final comparison in end(),
which only compares a nonempty _target_md5 (Updater.cpp:303-308).
Set the supplied MD5 after Update.begin succeeds. If the digest is rejected,
abort the begun update, release upload admission, and return HTTP 400 before
assigning an owner or extending its receive timeout.
Model the pinned begin-clears-digest behavior in the host fixture using
independent digest vectors. Verify malformed and mismatched digests, actual
byte corruption, disconnect cleanup, and later valid admission. Negative
controls restore the original ordering and remove abort/busy cleanup.
Validation: python3 -B test/test_async_web_lifecycle.py -v passed 4/4,
including C++ ASan/UBSan execution and negative controls. No PlatformIO or
hardware validation was run in this worktree.
Bound ACL replies for encrypted routes, authorize Sensor ACL access using the actual Admin role, and preserve request retries after failed queue admission. Validate stored paths for replies, while keeping Room keep-alives direct-only.
Add both G3 RF-slot Sensor profiles, suppress battery alarms on unavailable measurements, and remove the unsupported Sensor WebConfig capability. Add executable regression coverage and CI checks.
Report the upload address and required network, honor AP switches on an existing uploader, and keep delayed WebConfig cleanup from disabling OTA WiFi. Preserve actionable startup errors and account for OTA in wireless state controls.
Exercise the production OTA lifecycle and stock website console, including power-saving idle sessions, in host regression tests.
Switch eight S3 board defaults and 78 remaining TinyUSB recipes to hardware Serial/JTAG while preserving UART and other platforms. Restore retained S3 PHY ownership after a TinyUSB OTA restart and prepare KISS queues before enabling the driver.
Add real recipe resolution, Companion/KISS transport sanitizer coverage, and RF lifecycle reset regressions to CI. Native tests pass 1765/1765; SDK, transport, recipe and USB watchdog checks pass. Board and role cross-compilation and physical OTA qualification continue.
