📖What it means

An agent is talkable-to, and the same actor in every conversation. Isolation is the FOUR-TUPLE (agent, user, project, window class): every conversation lives in exactly ONE environment, and internal, external and operator windows never share a store — an entitlement check plus a header stamp is not isolation. The experience is CHANNEL-INVARIANT: five prompt layers with one source each — the engine (persona, Mind, doctrine, grounding), the agent's brief, the tier, the person, and channel constraints — and only the last may differ per channel. Every door answers through the ONE engine; a door contributes configuration, never a second copy of a layer.

📖Easily confused with

[{"term": "Agent \u00b7 Memory", "distinction": "Chat is the door and the turn. Memory is what survives between them, and it belongs to the person, not the window."}]
