D. Shnaider (A, rank 20, age 22) vs A. Potapova (B, rank 38, age 25) - Washington, hard, 1/8-finals

MODELS vs MARKET
  ELO:    A 64.1%
  ML:     A 50.6%   (13-pt split from ELO)
  Market: book A 1.67 / Betfair A 1.75 (impl ~58.4% comm-adj) - B 2.05 / BF 2.10
  Betfair sits between the two models. ELO/ranking agree (20 vs 38) so ELO not "farmed",
  but ELO is heavily inflated by Shnaider's exceptional CLAY surge (FO semifinal, wins over
  Sabalenka/Keys) - no hard-court signal in the window to support 64%. ML (opponent- & form-
  adjusted) says pick'em.

RECENT FORM (last 5 each)
  Shnaider (grass/clay, now hard): 07-02 L Samsonova(1783) grass; 06-30 W Lys(1550) DOM;
  06-22 L Tauson(1610) grass straight; 06-15 L Bartunkova(1725); 06-04 L Chwalinska(1831) FO SF.
  -> Grass stretch FADING (lost to Avg Tauson), but grass is her weakest surface. Elite clay run
     before that. TRANSITION grass->hard. Last match 07-02 = 27 DAYS OFF -> rust risk, first hard match.
  Potapova: 07-29 W V.Williams(1325) hard 6-3 6-3 DOM - at THIS venue, match-sharp; 06-29 L Bouzas(1674);
  06-15 L Alexandrova(1764); 06-11 L Sonmez(1673); 06-10 W Lamens(1523) GRIND.
  -> Grass poor too, but has a live hard-court win yesterday + Rome TITLE in May (strong clay).

FATIGUE
  Potapova won a 2-SET match yesterday (68 min, straight sets) -> ~neutral, no extra-set haircut.
  Not an extreme spot. Age 25 baseline. Shnaider "well rested" = actually 27-day rust, not an edge.

NARRATIVE
  Path: Potapova match-sharp (1 match deep at venue, played-in). Shnaider rusty first-match + surface
  transition grass->hard. Played-in beats rusty outside extreme spots -> favours B, not A.
  No letdown. Both clay-strong, both grass-weak, neither with reliable hard mapping.

GATES
  G1 edge-origin: FAIL - the only numeric edge (ELO 64% vs BF 58%) comes from a SINGLE model that ML
     contradicts by 13pts and that is clay-inflated with zero hard-court support. Not a clean edge.
  G2 consensus:   lone-model (ELO only); ML agrees with market -> capped tier at best.
  G3 fatal-risk:  n/a (ML market).

VERDICT - PASS
  Edge is manufactured from one suspect model (clay-inflated ELO); ML and market roughly agree the
  match is a coin flip, and the qualitative sharpness read favours the OPPONENT (Potapova match-sharp,
  Shnaider rusty + transitioning). No bettable edge on either side: A at BF 1.75 needs a hard-court
  case the data doesn't show; B at BF 2.10 is ~fair vs ML. Professional outcome: pass.
