# GTA-UAV Baseline: no text fusion (gate forced to 1.0).
# query = drone_only -> InfoNCE vs satellite
# Reference R@1 for delta computation.
#
# Diagnostic mode (2026-04-24): DSS and hard-negative mining disabled after
# the previous run collapsed (R@1 = 0.6% at epoch 8, train loss growing).
# Hypothesis: DSS packs visually-identical drones at bs=8 and the hard-mining
# queue amplifies that hardness — together they prevent convergence from a
# nearly-random start. Run with mutex-only sampling and the full queue as
# uniform negatives first, restore the extras incrementally once baseline
# converges.
