The ward's bite gets its name, and shrink slips past the giant

Two chronicle truths from tonight's table: the cardless ward stack fell
through to 'punch from <owner>' — stacks now carry a sourceName, and the
bite reads 'warded treasure' as it always did pre-rev-9. And a SHRUNK
wizard walks straight through BIG MAN's square (table ruling: small
enough to slip between the giant's boots) — a widening, shipped ungated.
