The Subagent Invocation Framework (Sif): general doctrine for invoking another agent — any vendor, any arity — as bounded in-session capability, plus per-binding annexes carrying each binding's transport, tool-contract, and authority facts. Read before building or using any agent-invoking instrument; route to a concrete instrument (the-codex-dialogues, cricket, codex-helper) for the actual invocation workflow.
