Detailed Description

Primitive UUID - sparse identifier from Helios Context.

UUIDs are assigned by the Helios Context when primitives are created. They are persistent, unique identifiers but may be non-sequential (e.g., 10, 42, 100, 5).

Cannot be implicitly converted to size_t, preventing accidental use as array index. Must explicitly convert via UUIDPositionMapper.

// Correct usage:
PrimitiveUUID uuid{42};
ArrayPosition pos = mapper.toPosition(uuid);
float value = buffer[pos];  // pos converts implicitly to size_t
 
// Compile error:
float value = buffer[uuid];  // ERROR: PrimitiveUUID cannot convert to size_t
