Function runLoop

src/compiled/cognition/loops.js:24–109

* Run a bounded refinement loop. * * Executes `step()` up to `max_iterations` times. After each step, * calls `validate()`. If valid, returns immediately. If not, optionally * calls `critique()` to generate feedback for the next iteration. * * Always terminates. Never recurses. Fully traced.
