DATA QUALITY
Dong listed age 56, ranking 3 - clearly bad player mapping (real Dong is a young ITF-level player).
Savinykh age 35, ranking 1373. ELO/ranking sanity check unusable on side A - discount everything, lean PASS.
Dong's history shows overlapping events (W35 Saskatoon 07/22-24 AND Vancouver SF 07/25) - feed noise.

4-3 in last 7; wins vs Avg/Weak only.
FATIGUE (server-computed)
Dong: 4 matches/7d, 12 sets, 318 court-min, b2b 3, last 07-25
Savinykh: 5 matches/14d (1 in 7d), 15 sets, 416 court-min, b2b 3, last 07-26
Court-time diff ~98min heavier on Savinykh, but her recent week is light (1 match/7d).
Savinykh 35 (>=30, slow recovery) but the 7d load is minimal; Dong's age datum (56) is garbage - age-neutral.
Call: roughly a wash; no reliable fatigue edge either way given feed noise on Dong's schedule.
NARRATIVE
Let-down: none (no recent Final wins). Venue: both 1-0 at Vancouver (semis). No surface transition (hard -> hard).
GATES
G1 edge-origin: [FAIL] - ELO = market exactly on Dong; ML edge on Savinykh is +1.9% at book, below the 5% bar (and below the 8% book-priced bar with no executable exchange price)
G2 consensus: [FAIL] - no side has model-market disagreement to defend; ML and market agree Savinykh, ELO sits in between
G3 fatal-risk: [FAIL] - broken exchange quote (1.02/1.03) and corrupted player-A metadata (age 56, rank 3) make any staked number untrustworthy
VERDICT: PASS. Zero numerical edge (value_edge 0.0002), no executable exchange price, and bad data on the Dong side. Efficient market on a small ITF-level final - nothing to stake. Match-winner forecast: V. Savinykh (~73%).
