The spec: plan_write and plan_update (new, shared, offered in every mode) and plan_submit (now shared) keep one structured plan — findings, objectives, phases of tasks — in place of the todo list, which lives on as a former name of plan_write. The shared system text is one text for both projects, with variables for what differs; the mode texts, a prototypes block and a library block are shared. acp.md: the client hands the device what only it knows (context, library, prototypes), the plan travels as a structure (plan_state), library calls carry the chat's scope, and a client may rewind a session. loop.json says its numbers as numbers. Four conformance areas: plan, prototype, library_scope, toolcall_index. The CLI: the plan is kept per session in the store and drawn above the prompt and on the approval card; the prompt is assembled from the spec's texts with their variables filled; the link reads the instance's instructions, personalization, knowledge scope and prototype offer, sends the plan as a structure and answers rewind; library calls to the instance carry the session as scope; a prototype written in the terminal is saved as a file and named in the transcript; a tool-call fragment without an index continues the last call; the default theme is Moria; dead exports and Hermes leftovers removed.
