`fit: reduce` acts only on refusals marked too large. Three kinds weren't: the corner build's contact lines leaving their faces or running backwards, and a curved chain's contact reaching past the end of the seam it trims. Two more were hidden: a later edge's too-large refusal lost to an earlier edge's other error, and the corner build's lost to the local blend's in `fillet`. The messages are unchanged.
