mhome-llm-api

Canonical Rust model contract: messages, ordered content parts, model tool schemas, completion requests/responses, finish reasons, usage and private opaque continuation. service defines the /llm/complete invocation wrapper; node installation/management contracts remain in Core API.

A continuation records a versioned format, an opaque compatibility key and a losslessly serialized provider payload. Its Debug implementation redacts the payload. Adapters own codecs and key construction; callers must retain it with its original assistant message and must never show it as user-visible content. A changed route starts a new model context instead of forging reasoning.

schema/message.v1.schema.json is the offline message contract. Conversation's self-contained execution schema embeds the same definitions and has a drift test. Only Rust consumers currently use this package, so it does not introduce an unused npm package.
