420 AI concepts

A model ID identifies a model family; a model-version ID binds artifact/runtime/schema/verification semantics. Material changes require a new version.

A provider is the qualified AI service identity. ComputeMarket owns execution-resource/economic matching, while 420AI owns AI request/model/result semantics.

A result commitment commits to off-chain output bytes/manifest. It is not universal proof of truth or quality.

A verification profile defines what evidence is required before settlement may proceed.
