Module id 

BLAKE3-based deterministic ID generation for SAF entities.

All AIR entities use u128 IDs derived from BLAKE3 hashes, ensuring deterministic identification across runs (FR-AIR-002).

Functions

id_to_hex

Format a u128 ID as a lowercase hex string with 0x prefix.

make_id

Compute a deterministic u128 ID from a domain tag and arbitrary data.
