# #52 STANDING-LOCK -- A/B on the rig that is KNOWN to reproduce.
#
# Composition lifted verbatim from scratchpad/night12/skatebench.sh, which
# produced 6 skate episodes in one 260s run (sk_run.out) and 4 in another.
# A walks continuously (autodrive) and is killed every ~40s by B, so it
# respawns WHILE MOVING -- and that is the field correlation both nights:
# night 12's skating clustered in the deaths-heavy final drop, and all four
# of night 13's episodes were in the last, deaths-heavy session.
#
# My own rigs (skatelock.sh v1/v2/v3) each failed to reproduce the SYMPTOM:
# a wall-jammed mech locks but does not translate, and a freely-walking mech
# transitions gait constantly, so records keep rescuing its peer copy.  The
# kill cycle gives both halves at once -- a steady post-respawn walk demand
# with no gait edges, on a mech that is actually moving.
#
# B is the OBSERVER: A's replicant lives on B, so B's log carries [skate],
# [bodySM] and [peergait] for A.
#
#   MODE=legacy -> BT_NO_BODY_FALLTHRU=1 (pre-fix; expect episodes)
