# Eou Preemption Analysis Sweep

`GET /v1/admin/eou-preemption-analysis/sweep`

Threshold sweep + wiring diagnostic for the synthesized-PREFLIGHT lever.

Separates two hypotheses for why Smart Turn's first 0.7-crossing fires
after is_final:
  H1 — threshold too high: signal IS rising before is_final, just doesn't
        hit 0.7 in time. Lower threshold → earlier crossings.
  H2 — wiring issue: Smart Turn isn't *invoked* until late. Samples
        physically don't exist before is_final. No threshold change helps.

Per language returns:
  - first_sample_advantage_ms_*  — when the FIRST Smart Turn sample
      (any prob) fires relative to is_final. Positive = sample exists
      before is_final. Negative = no samples until after. This is the
      H2 diagnostic.
  - max_prob_before_is_final_*   — across the samples that DID land
      before is_final, what was the highest probability seen?
      Tells us whether lowering the threshold could possibly help.
  - thresholds: per threshold (0.3, 0.4, 0.5, 0.6, 0.7), the crossed_pct
      and early_advantage_p50. The H1 diagnostic.
