most software has no layer between the agent and the app, and that's the whole problem

Was thinking about this after a few weeks of watching agents work. Most software is two layers. The app and its logic at the bottom, the agent on top. Nothing between them. So the agent goes straight for the interface. Reading pixels meant for human eyes, clicking buttons meant for human hands. Nobody ever designed a layer whose job was deciding what the agent is allowed to see and touch, so every permission call is invisible. An agent-ready stack would have three layers. App at the bottom, agent at the top, and an access layer in the middle. The piece that decides what the agent can see and touch. That middle layer is where the real work is. Reads scoped to the field level — one record and every record are different doors. Writes that wait for a named human before anything actually leaves. Every step carrying its permission decision with it, visible in the log, checkable after the fact. That's the stack the last two weeks have been building toward. The translation layer, permissions and approvals, structured access instead of scraping, job descriptions instead of tools. All four live in the middle layer. Honest question: if you drew the middle layer in your own stack today, what would it refuse first?
