scema-sim

Counterfactual projection.

Part of Scematica Omni — an agent runtime that perceives an environment, projects competing futures, ranks them under a stated preference, decides or refuses to, and seals a verifiable record of what it did.

The organising idea across every crate: each layer can say "I don't know", and saying it costs nothing. An agent that cannot express ignorance expresses a number of the right shape instead, and nothing downstream can tell it from a measurement.

Takes a world, a goal and a set of hypotheses; returns expected gain, risk, cost, uncertainty and reversibility per branch — each a Term that says whether anybody measured it.

A projection may not invent a number.

A simulator that outputs +31% predicted performance for a refactor nobody benchmarked has produced a hallucination with a decimal point on it, and the decimal point is what makes it dangerous: it survives into a ranking, a report and a record looking exactly like a measurement. So StructuralSimulator scores an expected gain only from signals the observer actually counted.

The consequence is uncomfortable and correct: on a barely-perceived world most branches project exactly zero and the agent abstains. That is the true answer.
