Research direction

Start with the linked contracts issue 11, which contains the design and open questions, then inspect the partition table, BLE bond storage, release workflow, xtask/, and Cargo.lock. The work spans OTA slots, signature verification, config migration and rollback, safe mode, and generated app builds; done means these update, recovery, and release requirements are implemented.

Written by the indexing model from the issue text.

Description

Part of https://github.com/OpenCarControls/contracts/issues/11, which has the design and open questions.

  • Partition table with OTA slots; move the BLE bonds to a data partition first.
  • Verify the image signature (ideally with secure boot).
  • Keep user config across updates (migration and rollback); wipe it when flashing for another car.
  • Safe mode when the wrong car is detected, with setup and reset.
  • Trigger releases on contracts bumps, xtask/ and Cargo.lock changes.
  • Pin a lockfile for the generated app build instead of deleting it.
