Platform architecture

  • VHAL ownership and vehicle-property contracts are documented
  • vehicle signal validation and failure behavior are defined
  • Android service boundaries are understood
  • product-specific framework modifications are controlled

Diagnostics

  • boot timing is measured
  • log collection survives field failures
  • vehicle-property failures can be traced end to end
  • ANR/crash/performance diagnostics have an operational workflow

Security

  • permissions and SELinux policy are reviewed
  • debug interfaces are controlled for production
  • OTA/update provenance is defined
  • sensitive vehicle functions have explicit authorization boundaries
