Heltec V4 timing measured 2.19 seconds for recovery checks, temporary-file cleanup, open and buffer configuration combined in one lazy-save pass. Defer those startup operations across guarded companion loops while explicit durability callers still initialize synchronously.
Track ownership only after attempting to create the temporary file, preserve unowned stale files on early cancellation, and reject premature writes or commits. Cover startup faults, interruption, mutation, cache pressure and synchronous-construction negative controls with native sanitizer tests.
Extend the cooperative contact transaction to uncached ESP32 storage,
including the PSRAM policy used by the XIAO and V4. Preserve owned contact
copies, the 152-byte disk format, revision cancellation and synchronous
durability operations. Keep contact capacities unchanged.
Avoid SDK error logs when optional blob or transaction cleanup files are
absent, while preserving metadata and deletion failure handling.
Validate cached ESP/nRF and uncached PSRAM paths under ASan/UBSan,
including bounded writes, mutation cancellation, faults, recovery and
reboot readback. Update the existing uncached production fixture.
Integrate PowerSaving-v17 through a27e78e4 (six new commits).
Use its 10-minute awake / 30-minute asleep companion GPS profile and
separate requested GPS state from receiver power in CLI diagnostics.
Include its nRF52 sensor debug-console settle delay and debug option.
Resolve overlapping GPS v2 changes using the current sensor callbacks,
which already implement live power-saving transitions, user-off control,
telemetry acquisition, wrap-safe sleep/wake timers and retained Airoha
RTC backup. Preserve preference persistence, telemetry cache/holds and
UART/shared-rail ownership safeguards across all four GPS drivers.
Add a compiled production GPS status regression test and run it in CI.
Validated 23 native GPS/power tests, preference and nRF52 pin contracts,
and firmware builds for T1000-E BLE Companion, MeshTracker X1 USB
Companion, Heltec Tracker Repeater, Mesh Solar Room and RAK4631 Sensor.
Import Airoha GPS RTC backup sleep, 24 contact search results, and the T-Echo Lite USB companion target. Preserve existing GPS telemetry and power-saving controls, crypto alignment checks, ESP32 RTC recovery, and RAK11310 dynamic-preference compatibility.
Validate GPS sleep acknowledgments with their NMEA checksum and add six native regression tests covering retry, drain, corruption, grace timeout, and timer rollover.
Verified: 1648 native and KISS modem tests; targeted nRF52, companion routing, one-key DM, and clock checks; T1000-E BLE, MeshTracker X1 USB, and T-Echo Lite USB companion builds.
