# arms_tfil_shape.txt — j146: the TFIL FIELD SHAPE, five arms on the frozen
# movement panel (tools/ab/panel_movement.txt), all with TR_MOVEMENT=tfil pinned
# EXPLICITLY and the j144 fixes ON, so only the SHAPE varies.
#
# WHY. The strafe sweep (j119 batch 4) already measured the field SHAPE, not the
# engine: the shape tfil SHIPS (corridor 20, wall 30/10) was -0.29 wins/run
# (p=0.039) and field_off was -0.47 wins/run (p=0.0063); the champion was the
# MIDDLE shape (bullet core 20 / aura 10, corridor 10, wall 15 / radiance 5).
# tfil has never been run on the middle shape. On top of that, j145 found 59% of
# tfil's picks have no safe set to tie-break in, because corridor 20 is TWICE
# PathDangerThreshold 10 and tfil's own bullet heat (core 10) is exactly the
# threshold, so a bullet is never dangerous by itself.
#
# Every arm carries `TR_TFIL_COMMIT_ARRIVAL=1 TR_TFIL_NOREV_SPEED=4` (j144's
# recommended .env) so the shape is isolated ON TOP OF THE CURRENT BEST TFIL.
# The pillar stays OFF (shipped default 0/0) in every arm.
#
# Columns: CORRIDOR / WALL_HOTNESS / WALL_RADIANCE / BULLET_CORE / BULLET_AURA

# 1. THE ARM TO BEAT — the field tfil ships today (20/30/10/10/5), on j144.
shape_shipped | TR_MOVEMENT=tfil TR_TFIL_COMMIT_ARRIVAL=1 TR_TFIL_NOREV_SPEED=4 TR_TFIL_CORRIDOR_HEAT=20 TR_TFIL_WALL_HOTNESS=30 TR_TFIL_WALL_RADIANCE=10 TR_TFIL_BULLET_CORE=10 TR_TFIL_BULLET_AURA=5 | today's shape, on j144 (control / reference)

# 2. THE CANDIDATE — the shape strafe measured as the champion.
shape_middle | TR_MOVEMENT=tfil TR_TFIL_COMMIT_ARRIVAL=1 TR_TFIL_NOREV_SPEED=4 TR_TFIL_CORRIDOR_HEAT=10 TR_TFIL_WALL_HOTNESS=15 TR_TFIL_WALL_RADIANCE=5 TR_TFIL_BULLET_CORE=20 TR_TFIL_BULLET_AURA=10 | the middle shape strafe won on (10/15/5/20/10)

# 3. "corridor alone was the problem" — only the corridor is halved.
shape_corr10 | TR_MOVEMENT=tfil TR_TFIL_COMMIT_ARRIVAL=1 TR_TFIL_NOREV_SPEED=4 TR_TFIL_CORRIDOR_HEAT=10 TR_TFIL_WALL_HOTNESS=30 TR_TFIL_WALL_RADIANCE=10 TR_TFIL_BULLET_CORE=10 TR_TFIL_BULLET_AURA=5 | shipped, corridor 20->10 only

# 4. "bullets made dangerous themselves" — only the bullet's own heat is raised.
shape_bullets | TR_MOVEMENT=tfil TR_TFIL_COMMIT_ARRIVAL=1 TR_TFIL_NOREV_SPEED=4 TR_TFIL_CORRIDOR_HEAT=20 TR_TFIL_WALL_HOTNESS=30 TR_TFIL_WALL_RADIANCE=10 TR_TFIL_BULLET_CORE=20 TR_TFIL_BULLET_AURA=10 | shipped, bullet core/aura 10/5 -> 20/10 only

# 5. THE "field off" CONTROL — corridors, walls and pillar all zero, so the
#    bullets' own heat is the only bullet threat. strafe measured this shape as
#    the WORST of the three; it is here so a middle-shape win cannot be a false
#    winner (it proves the win is the middle, not simply "less lava").
shape_nofield | TR_MOVEMENT=tfil TR_TFIL_COMMIT_ARRIVAL=1 TR_TFIL_NOREV_SPEED=4 TR_TFIL_CORRIDOR_HEAT=0 TR_TFIL_WALL_HOTNESS=0 TR_TFIL_WALL_RADIANCE=0 TR_TFIL_BULLET_CORE=20 TR_TFIL_BULLET_AURA=10 | no corridor/wall field, bullets only (0/0/0/20/10)
