  "$comment": "Proposed for OpenEik 0.2: Part XVII, commands with an envelope. Written by hand from Part XVII, not generated: tools/generate-schemas.mjs keeps this folder and lists none of it in index.json. No file of a model is held to it: an envelope and an answer are what a writer sends a command processor and what it answers, not files of a folder. A command processor applies it only when asked for the proposal (@openeik/tools: proposals [\"envelope\"]).",

It is a schema that asserts nothing: its member x-eik-proposal names the two messages the proposal adds, the envelope a writer sends and the answer a processor gives, with their schemas, and the precondition each command kind takes in an envelope. Schema paths are relative to https://openeik.org/schemas/0.1/.",
