Companion

Longest profile name DICE accepts. A reference is an identifier the host mints, not a place to smuggle a payload, and extraction runs will store these — so the bound exists to keep a stored run header from growing without limit. Any real profile name is far shorter.

Longest profile version DICE accepts. Same reasoning as MAX_NAME_LENGTH; versions are short by nature (v3, 2026-08-01, a commit sha).
