What it does

• Each node declares its allowed choices up front, as part of the node's outgoing paths. No global list, no free-form routing. An assess node might allow only needs_investigation or well_documented; the same label on a different node can mean
• The model's decision tool only accepts those choices. If it picks anything else, the tool call returns an error listing the valid options, and the model tries again. Typos and made-up names fail fast instead of quietly leading the workflow
• A legal choice with no matching path halts the run. If the model picks an option that's valid in theory but no real path is wired up for it, the engine stops and logs it rather than drifting.
