Captures action_val + decoded dir/mag, max_position, prev_position,
position post-trade, actual_dir, actual_mag, trail_triggered,
conviction, health, value, max_equity inside backtest_env_step_batch.
Localises which step in unified_env_step_core zeros target_position
(or position) for non-Hold picks.
After tracing the math, every analytical candidate (margin cap, Kelly
cap with health-coupled warmup floor, trail stop) returns a positive
target at cold start with my fix. val_dir_dist still locks at 0% Long
while val_picked_dir_dist shows 17% Long — only direct kernel-side
observation can show what's actually clamping.
Removed once the gate is identified.
