What the agents hold to

A path is worth following only if it goes where it says. The Corpus makes that true for an agent.

A company has already written down most of what its agents need: policies, procedures, answers someone gave last year. A model that reads a policy paraphrases it, and every paraphrase drifts a little.

The Corpus keeps the text as written, and every version of it. An answer comes back with its passage, checked word for word. The engine makes each decision, not the model, so the same facts return the same trace. When the documents do not say, the Corpus says so, and the agent has to ask someone.

That lets agents take on more. An actor that improvises the rules must be watched at every step; one that acts only from what was written can be given more steps, because anyone can check where each came from.

In the mark, the Corpus is the ground the routes are drawn on. It does not choose the route. It decides which routes exist: the ones the company's own words allow.

Rules change. A new policy version is published and every later answer cites it; old answers still point at the version they read.

The Corpus is for the people who write those rules and the developers who connect them to agents.
