Remark. The runtime ingredients of a model artifact [ftip-006M]
✍️source

    Section 6 of [phuong2022formal] describes decoder architecture. Sections 3.1 and 3.5 of [kudo2018sentencepiece] treat the tokenizer as a separate model. Public model releases additionally distribute weights, configuration, and numerical conventions. The proposed artifact model in Definition [ftip-001K] includes these runtime ingredients because none alone determines an executable next-token law.

    Training provenance accompanies the artifact but is not itself a runtime argument. Later causal claims must distinguish the executable endpoint from the process that produced it.
