Hypothesis test for SP22 H1 (label horizon mismatch).
Finding from v9/v10 HEALTH_DIAG: aux_dir_acc=28-47% (BELOW RANDOM)
across all observed cycles. Root cause: adaptive aux_horizon_update
collapses H back to ~1.7 bars (observed avg winning hold time),
making the aux label HFT microstructure noise.
Experiment:
1. Bump SENTINEL_AUX_PRED_HORIZON_BARS 60.0 → 200.0
2. Disable launch_aux_horizon_chain call so H stays at sentinel
Predicted: if aux_dir_acc rises >50% → H1 confirmed; if stays ≤50%
→ escalate to H2/H4 per SP22 plan.
Cost: 1 smoke ~30min, kill early on cycle 1-2 trend.

Reverts if H1 falsified.
