  • Default name is board name (e.g., "Adafruit Feather M4 CAN")

Platform-Specific Rule Limits:

  • CAPS response now includes max_rules field
  • Feather M4 CAN (SAMD51): 64 rules
  • Raspberry Pi Pico (RP2040): 16 rules
  • ESP32: 32 rules (when implemented)

🧪 Testing & Quality

  • 269 hardware-independent unit tests (protocol parsing & validation)
  • 8 new device name integration tests
  • All tests pass in CI without hardware
  • Comprehensive test coverage for device naming feature

📚 Documentation

  • Complete set:name command documentation in PROTOCOL.md
  • max_rules field specification added to CAPS response
  • Device naming use cases and limitations documented
