E. Navarro (A, #15, age 25) vs S. Kenin (B, #28, age 27) — Washington, HARD, 1/16-finals

═══ MODELS vs MARKET ═══
ELO 57.0% | ML 64.0% | blend 63.6% (Navarro). Betfair ML 1.42/3.3 → implied 70.4% Navarro.
Sim (resimulate baseline): Navarro win 57.3%, expected margin 1.2 games, total 21.0.
Note the spread: sim+ELO cluster at 57%, ML at 64%, market at 70%. The market is the high outlier
and the sim/ELO the low outliers — ML sits in between.

═══ RECENT FORM (last 5 shown; all fetched used for read) ═══
Navarro (A): grass block, then 23-day layoff + grass→HARD transition.
  W Wimb vs Selekhmeteva(1551) 3-6 6-4 6-1 (3set) | L Wimb vs Kostyuk(1665) | W Wimb vs Badosa(1720) 4-6 6-3 7-5
  W BadHomburg vs Swiatek(1990 Elite!) 3set GRIND | L BadHomburg vs Ruse(1824). Also Strasbourg CLAY title 05-23.
  Read: legit top-15, quality wins over Swiatek/Badosa, but a GRINDER — wins go 3 sets/tiebreaks, rarely blows opponents out.
Kenin (B): 25-day layoff + grass→HARD transition. Lost 7 of last 9.
  L Wimb vs Anisimova(1878) 6-2 4-6 7-6(tb) competitive | W vs Marcinko competitive | L Eastbourne vs Snigur 3-6 1-6 BLOWOUT
  L Nott vs Golubic x2 | L RG vs Stearns 3-6 3-6 | Read: FADING/weak form; mix of tight losses AND blowouts (Snigur, Stearns).

═══ PATH / SHAPE / RUST ═══
Both rusty (>21d off) and both grass→HARD — differential neutralizes. Neither match-sharp at venue (round 1).
Shape: Navarro STABLE-to-strong (Elite scalps); Kenin FADING (7 of 9 lost). Fade points AT Kenin, not for her.

═══ FATIGUE ═══ Both well_rested (0 matches 14d). Non-factor. No age modulation needed.

═══ NARRATIVE ═══ No first-Final let-down window in play. Navarro: Strasbourg TITLE 05-23 (clay, 65d — stale, live grass form outweighs).
Surface TRANSITION both sides → widens margin variance for a cover (cuts both ways) = cover RISK, not support.

═══ SIM VALIDATION (resimulate stress test) ═══
Baseline inputs built on GRASS/clay (23 matches each), NOT hard: Navarro spw .570/rpw .413; Kenin spw .557/rpw .412.
Convergence check FAILS: sim 57.3% agrees with ELO 57.0% but diverges from ML 64% + market 70% + the qualitative class gap.
Stress test — rpw_a .413→.45 (justified: Navarro elite returner, grass understates hard-court return, +0.037 within clamp):
  → Navarro win 57%→75%, margin 1.2→3.3, Kenin +3.5 cover 57.3%→38.4% (NEGATIVE edge).
Add spw_b .557→.53 (Kenin grass serve overstates hard): → Navarro 85%, Kenin +3.5 cover 26.2%.
Conclusion: cover distribution is knife-edge on the serve/return inputs. The 8% baseline cover edge exists ONLY because
the sim (like a depressed ELO) underrates Navarro. Once her real class edge (ML/market/form) is priced, the cover vanishes.

═══ MARKET-BY-MARKET ═══
- ML Navarro: model 63.6% < effective 71.5% (Betfair 1.42) → negative. No.
- ML Kenin: model 36.4% vs effective 31.4% (Betfair 3.3) → ~5% edge, but rests on the same underrating; form argues AGAINST. No.
- AH Kenin +3.5 @2.10: baseline edge ~8% but fragile (→ -ve under justified re-run) + fatal-risk live. No.
- AH Navarro -3.5 @1.83: baseline cover 42.7% (neg); true value hinges entirely on the contested win prob → coin flip. No.
- Total 21.5: over 0.495 / under 0.505 both negative at 2.0/1.93. No.

═══ GATES ═══
GATES
  G1 edge-origin: FAIL — Kenin +3.5's 8% cover edge exists only at baseline sim (57% Navarro ≈ depressed ELO); a justified rpw_a +0.037 correction collapses cover to 38% (negative). Edge not robust to a defensible input.
  G2 consensus:   FAIL — Kenin value (ML or cover) sits against ML 64% + market 70%; only a lone ELO/sim split supports it, and live form (7 of 9 lost, Snigur/Stearns blowouts) argues AGAINST her. No H2H / live-event evidence.
  G3 fatal-risk:  FAIL — cover thesis negated if Navarro plays to class (stress: margin 3.3+, cover 38%); Kenin's recent blowout losses (3-6 1-6, 3-6 3-6) are exactly the negating scoreline. Units cannot buy this back.

═══ VERDICT: PASS ═══
Every apparent edge traces to the sim/ELO underrating a clearly superior, better-form Navarro (rank 15, Swiatek+Badosa scalps)
against a collapsing Kenin (rank 28, 7 of 9 lost). ML and market both price Navarro higher, and the cover edge evaporates under a
modest justified re-run. Manufactured-edge signature — no robust, validated edge in any market.
