Absolutely agree. Agent identity is an important missing layer in the autonomy discussion. The key distinction is moving from “the user authorized this” to “this specific agent, with this specific scope, performed this action.” That gives you much stronger provenance, auditability, and accountability. I also like the checkpoint model here because identity + scoped authority makes checkpoints more than just approval gates—they become enforceable policy boundaries. As agents become more autonomous, that combination could be critical for making autonomy trustworthy rather than simply convenient.
