+Full USB logging repair — 1.17.1.6
+Audit date: 2026-09-13. Release firmware source: 306feebe6d648a247f925894f876be9d747fc8d2.
+The original Station G2 Full Repeater and Full Room Server images omitted USB
+packet logging. Both inherited -UMESH_PACKET_LOGGING from their ordinary MQTT
+observer recipes. Full added -DMESH_PACKET_LOGGING=1, but PlatformIO's
+ProcessFlags moves undefines after defines in the compiler command. The
+resulting image compiled successfully with its packet logger removed.
+The previous release gate checked OTA and other features without requiring
+USB logging in Full infrastructure. An old passing manifest could also be
+reused by --resume without the new logging evidence.
+Published-image audit
+Each downloaded/cached artifact was matched to GitHub's published SHA-256.
+The check inspected application bytes, including the application inside nRF52
+DFU ZIPs. It required the packet-log formatter and USB logging controls.

+V4/R8 Full builds and Station G2's Full ESP-NOW bridge passed. This audit does
+not count ordinary MQTT profiles that intentionally omit USB logging as
+broken. Artifact inspection proves compiled support, not hardware operation
+on every board.
+Fix and regression coverage
+
+- Full builds that require logging remove inherited disables of
+
MESH_PACKET_LOGGING before PlatformIO parses flags. Other macros and
+ explicit logging-off profiles retain their policy.
+- Full capability checks require the packet logger and USB controls in the
+ packaged application. Combined USB/WiFi profiles additionally require
+ the
logging.output setter. ELF symbols or debug text cannot satisfy these
+ checks.
+- Resumed builds must have passing application evidence for the current
+ logging contract, along with the existing artifact hashes and RAM checks.
+- CI runs the flag, real PlatformIO/compiler, artifact, resume, and build-profile
+ regression suites.
+
+Focused verification (after installing PlatformIO and its tool-scons package):
+python3 -B test/test_full_build_flag_dedup.py
+python3 -B test/test_full_logging_compile.py
+python3 -B test/test_firmware_capabilities.py
+python3 -B test/test_full_logging_resume.py
+bash test/test_build_profiles.sh
+python3 -B test/test_cascade_release_package.py
+
+Both Station G2 profiles were rebuilt through build.sh --full with the
+original observer recipes, including their inherited logging undefines. They
+passed the new application checks, runtime RAM budgets, and both OTA slot
+size checks. The new checker rejects both original published images.
+On the Bellevue Station G2, the corrected Full repeater implementation also
+passed serial CLI and passive traffic checks: four RX and two TX packet log
+lines were captured. Its active temporary profile retained preamble 120 and
+the original schedule end time; the Pi relay services were restored.
+Corrected application SHA-256:
