Recheck cached immutable paths before resetting the live table after raw I/O failure. Keep accepted RAM mutations, current jobs and save deadlines when reads recover; stronger source or publication uncertainty still forces full recovery. Use the existing recovery byte and a fixed scratch buffer, with no cache allocation or eviction.
Cover full-cache transient recovery, persistent I/O and checksum failures, nRF unread-scope restoration, active ESP jobs, real uncertain publication and unchanged lazy deadlines with sanitizer tests and restored-reset negative controls.
Do not classify legacy or page-name stat errors as unread payloads. Keep candidate contact files unchanged, retry source selection, and use bounded volatile operation if authority remains unknown. Cover legacy absence, downgrade leftovers, cleanup-time metadata recovery and persistent faults with actual-source sanitizer tests and restored-bug negative controls.
Verify fallback namespace moves before accepting publication or rollback. Reload readable contact images at a safe host boundary, discard only unreadable contact data after bounded retries, and permit volatile operation when storage cannot recover. Preserve unrelated stores and fail explicit durability requests truthfully.
Keep existing flash, RAM, OTA and capability limits by streaming nRF52 preferences through the validated wire table and sharing identical contact deadline resets. Add fault-injection, sanitizer, legacy-image parity and CLI lifecycle regressions.
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.
