TWO-LIST architecture confirmed (list-0 base $83 / list-1 base $8C, tails $DC/$DD)

THE REAPER RUNS EVERY COUNTDOWN FRAME BY DESIGN (the F150 quiescence hypothesis is refuted). So either (a) $FE16 is supposed to write the terminator after the last entry and a diverged branch skips it, (b) the terminator is supposed to come from the $F121 init which is gated behind the very countdown the reaper runs during (circular — unlikely; hardware boots fine), or (c) $FE16 terminates via a path involving the appender ($144B STA $84,X) that our flow…
