Use the committed node credential for setup WiFi, WebConfig and browser OTA. Add persistent ESP32 WiFi Companion management credentials without changing preferences layouts, revoke stale browser sessions on rotation, retain scoped save receipts, and coordinate credential changes with flash uploads. Keep external-service credentials and trusted TCP protocol compatibility independent. Update live join QR codes, failure handling and documentation.
Validated 51 native cases, 158 related host and browser methods, and serial Full V4 Companion, Station G3 Repeater, ESP32-C6 Room Server and V4 Sensor firmware builds.
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.
Patches Bluefruit library to fix semaphore leak bug that causes device lockup
when BLE central disconnects unexpectedly (e.g., going out of range, supervision timeout).
