Article 12 asks a high-risk AI system to record events automatically over its lifetime. For a fleet of agents, that is an architecture question before it is a storage question. What the text asks, why logging at a choke point beats logging in the agent, why self-written logs are weak evidence, and where Intramedial's record helps and where it does not.
A ledger bundle is checked with two operations: rebuild a Merkle root, then verify one Ed25519 signature. This walk-through does both by hand in a few dozen lines of JavaScript, with no account, no API key and no call to Intramedial, and then shows the same check with the offline verifier.
A signed ledger bundle is strong evidence of one narrow thing. Here is that thing, stated exactly, the three trails behind it, and the seven things a valid signature does not tell you. Read this before you hand a bundle to an auditor.
Two calls do most of the work in a coordinated fleet. Admission says whether an action is allowed. A lease says who holds a resource right now. Here is how each one answers, why they are separate, and what neither of them does.
Agents that share repositories, tools and cloud accounts collide in ways nobody planned for. Intramedial is the Agent Coordination Plane: agents declare what they are about to do, the plane answers before they do it, and every answer goes on a record you can check. Here is what it is and where it stops.
