03's sharpened settle rule: rendering the arrangement means rendering the card — at release the shadow swaps for the dropped card(s) drawn in place immediately, the appear never waiting for the echo reload. The committed hold now carries the landing (ids, payload titles, operation) and surfaces read one DropLanding seam: within-board moves draw the real faces at their proposed slots under the arriving card's own key, so the echo is an invisible content swap; cross-board card arrivals draw payload-titled faces keyed positionally, so the echo reads as an ordinary arrival. Cross-board lane arrivals deliberately keep their shadow until the echo — a lane's face is a whole column with no honest payload equivalent. The 1500 ms failed-write timeout is now seamed (injectable duration, extracted expire) and pinned by tests. Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
