Records and Arrays

Records and Arrays

Records reserve subindex 0x00 for the read-only entry count. Explicit field subindices from 0x01 through 0xFE are reserved first. Remaining fields are sorted by qualified name and allocated with CRC32 plus wraparound linear probing over exactly 254 slots. The field key is its qualified name without a category prefix:

PressureSensor.calibration.offset

Arrays also reserve 0x00 for the count, then always use standard sequential CANopen semantics:

0x01 element 1
0x02 element 2
...

Array elements are never hashed. Schema v1 supports lengths from 1 through 255.
