DATA CAVEAT: tournament label ("Toronto Final") does not match either player's recent-match tournament tags (A: Memphis Qualification / W100 Evansville; B: Vancouver / Wimbledon). Metadata reliability is questionable — bias toward caution.

  Day (B), rank 256, age 26:
    07-28 L vs Hontama 1545 7-6 3-6 4-6 — lost to Avg opp
    ~4-week gap before that (last activity 06-30). Wimbledon-window results in June (mislabeled "Final" in data).
    Shape: FADING/RUSTY — 1 match in ~4 weeks, a loss. Rust risk (>21d inactive before last match).

PATH / FATIGUE
  A match-sharp; B rusty. But A carries load: 3 matches/7d, 462 court-min/14d, back_to_back, and WON A 3-SET MATCH the day before this final.
  Calibrated 3-set-hangover haircut -4.5pp on A (hard, surface-agnostic; age 23 baseline, no modulation). Applied once, not stacked.
  A ELO 66.1% - 4.5 = ~61.6%. Betfair 1.70 -> commission-adj eff 1.665 -> breakeven 60.1%. Edge ~1.5% — below 5% bar.

ELO/RANKING: ELO (A fav) agrees with ranking (106 < 256) directionally, but Day's ELO likely depressed by inactivity -> ELO may OVERSTATE A's edge. Discount ELO's 66%.

GATES
  G1 edge-origin: FAIL — pre-fatigue ELO gives ~6% vs market, but it rests solely on trusting an ELO the ML flatly contradicts and that is inflated by B's stale/depressed rating; post-fatigue the numeric edge collapses to ~1.5%, below bar.
  G2 consensus:   PASS (stake-tier only) — lone-model (ELO) support; ML neutral.
  G3 fatal-risk:  n/a — ML market; G3 does not block ML.

VERDICT: PASS. The one clean qualitative edge (A sharp vs B rusty) is already priced into A being a clear favorite. Models split with ML at coin-flip; ELO likely inflated by Day's inactive rating; A's 3-set-win-yesterday haircut pushes her post-fatigue prob (~61.6%) essentially to the executable breakeven. No confident >60% on A, and backing rusty/lower-ranked B on a neutral ML against ELO and the qualitative read would be manufactured. No edge either side.
