# arms_gun_b2.txt — BATCH 2 of the GUN campaign: a WIDER-PANEL calibration of the
# two arms that carried the only nominal positive signal in Batch 1.
#
# Batch 1 (docs/gun_campaign.md, 15-opponent frozen panel, 270 battles) found NO
# arm beating the shipped `pattern` beyond the MDE, but two arms sat on the
# positive side of damage with a flat win count:
#     BitBrain  Δdmg +10.3 (11/15 opponents, sign test p=0.1185, sign-flip
#               p=0.0325), Δwins +0.11 (MDE 0.35)
#     TMHorizon Δdmg  +8.7 (11/15, p=0.1185, sign-flip p=0.0992), Δwins +0.13
# Both damage effects are BELOW the Batch-1 MDE (~12-14 dmg/run), so rule 3 says
# they are not detectable — they must not be called a win OR a null. Resolving
# them needs more OPPONENTS, not more runs, so this batch re-runs exactly those
# two arms plus the reference on tools/ab/panel_gun_b2.txt (33 opponents).
#
# Format:  name | ENV=value ENV=value | label
# MOVEMENT IS PINNED (`TR_MOVEMENT=strafe`) in EVERY arm — same rationale as
# Batch 1: a default flip may be landing from j120, and the pin makes every
# delta a pure gun delta and satisfies the analyzer liveness rule.
