NARRATIVE
  LETDOWN: Costoulas won Final 1d ago → live letdown window.
  NOTE: Aksu lost that same Final 1d ago.
  Venue: Costoulas 2-0 Prague; Aksu 1-1. TITLE: Costoulas — Prague 1d ago (clay).

VERDICT: PASS
  ML's 46.5% on Aksu is contradicted head-on by yesterday's direct result and a
  2-0 straight-sets H2H for Costoulas; ELO sides with the market. The letdown/
  fatigue angle on Costoulas is offset by her dominance over this exact opponent,
  and the duplicate-final data anomaly adds ungradeable risk. No stake.
