`45a7176` composes a box down its move chain on a grid fine enough to round once instead of once a level. `Holds::through`'s two-route allowance is two half steps where it was three, and it cost nothing: 1,880M instructions and 755M cycles against 1,908M and 760M, with all twenty-five work counters identical. What paid for the widening is that a length composes on its own in half the multiplies both ends of a box need, and that only the fraction needs the extra room. The i64 item in "Next" keeps the measurement that redirected it, since aiming the work at the screen invariant would have been wasted. One half step further is arithmetically available and not taken: shrinker seed 220 on `reorder` then diverges warm against cold, by re-breaking a wrapping text whose reported width moves a `Branch` onto its other subtree. That is written up under the `Holds::through` invariant with its reduction command and its ten-widget tree, and it is the next thing to chase. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
