# Seam-flag sweep for the top (topTest1 / pari). Diagnostic, exports nothing.
#
#   python tools/md_bridge.py --file tools/tailor/md_pari_seamsweep.py --timeout 880
#
# WHY: the untextured back render shows the back panel rucked up with its REVERSE
# FACE exposed. Reverse faces mean the seam is twisting the panel, not that there is
# surplus cloth — so the fix is the seam pairing, not the pattern.
#
# md_pari.py sews same-index with (False, False). The skill's rule is "pair the same
# line index on MIRRORED front/back panels with (False, False)" — but these panels
# are NOT mirrored: both are the identical point list, only offset by dx. Sewing
# front-right to back-right on non-mirrored panels needs one edge traversed in
# REVERSE, which is what the two booleans do. md_piupiu_v3.py sidesteps this by
# pairing right<->left, which is equivalent to a reversal — and it drapes clean.
#
# Sweeps the two flags on the SIDE seams only, keeping shoulders at (False, False)
# since the front and shoulder line look correct. Also tested separately and
# DISPROVED: crossing every pair (7<->9 AND 0<->5) makes the garment slide to the
# hips, because cross-wired straps cancel and it falls off the shoulders.
#
# 4 combos x Simulate(200) ~= 3 min. Reads back the turntable rear frame per combo.
