the sculpt wires into the product flow

The proportion and volume sculpting work was measured and gated, but had no real user-facing path yet. That debt got paid: a new command line tool measures a reference image’s proportions and volume ratios into one deterministic file, and both the manual tool and the interactive in-app action now call the same shared function underneath, so they can’t quietly drift apart. The real proof was ordering: sculpt once at rest pose, then animate, and the sculpt has to survive byte-identically. It does, frame-one drift came out effectively zero across seventy checks.

Three real bugs earned their keep. First, two test rigs sharing one scene made solved values look wrong, the real cause was one fixture already carrying an earlier sculpt while the other’s baseline measurement accidentally captured the overlapping shape of both figures at once. Took a full debugging ladder to isolate, fixed with a clean scene per case, a lesson the project had already learned once before, now learned twice.

Second, baking an animation shifts frame numbers by one internally, so comparing a frame against its own neighbor instead of itself made results look dramatically worse than they actually were. A one-line offset fix, with the reasoning written directly into the check itself this time so it can’t get silently lost again.

Third, comparing raw bone positions across an animated sequence turned out to be the wrong check entirely, since a position-based re-solve is supposed to compensate for the current pose’s rotation by design, not match it exactly. Redefined what the check actually verifies, and caught a related bug along the way: an assigned animation silently overrides a rest-pose snapshot unless that animation gets explicitly muted first.

Landed with fifteen new tests, the full suite green, and every number comfortably inside its bar except one, a single rig type’s re-sculpt accuracy sits just barely over target, left as the next rough edge.
