"""GUTE bridge — map equation terms to lab slices that compute real numbers.

Policy: one slice at a time, small and honest. LC is the seed.

A slice is a function that takes a GUTE term and returns a dict of
computable numbers and a one-line interpretation. It does NOT prove the
term is metaphysically real. It shows that the term has a computable
referent whose behavior is well-defined, bounded where claimed, and
unbounded where the metaphor breaks. Council experts can reason from the
numbers instead of from vibes.

Growth: new slice when a new GUTE term has a specific falsifiable claim
attached. Not before. Each new slice should ship with a pre-reg.
