RECENT FORM (last 5)
  Humbert: 07-28 Won A.Martin(1566) 6-2 7-5 hard DOM (Washington opener; grass to hard transition already navigated, 1 match deep = match-sharp on hard). 06-30 Lost Bergs(1717) 5-set grass. 06-28 Lost Bergs(1717) Final grass. 06-26 Won Draper(1866) grass. 06-25 Won Halys(1610) grass. Reached a grass final; STABLE.
  Shelton: 07-28 Won Damm(1734) 4-6 6-4 4-6 hard - grinding 3-set, 145min. Grass TITLE 06-14 beat Fritz(2004) Final; wins tiebreak/3-set heavy (Lehecka triple-TB, Giron 2 TBs). STABLE but wins CLOSE and LONG, rarely blowouts.

FATIGUE
  Both played 07-28. Humbert 90min 2-set win = neutral (~-2pp, round-progression only).
  Shelton won a 145min 3-SET match yesterday, calibrated -4.5pp hangover haircut; age 23 = baseline (no softening). Real factor but per calibration next-match win rate barely moves; may only CONFIRM an existing numeric edge, cannot create one.

MARGIN MARKETS (resimulate calibrated distribution)
  Expected total games 22.1 (RAW 25.1, bias-corrected -3.0). Expected margin A -1.8 (competitive).
  Total Under 24.5 at 2.0: sim 63.9 pct vs comm-adj 51.3 pct = +12.7 pct nominal. BUT this edge exists ONLY via the -3.0 calibration; the RAW sim projects 25.1 games (OVER), and the style/scoreline read agrees with OVER: two big servers on hard (spw .637/.604, holds .875/.85), Shelton history packed with tiebreaks and 3-set wars, tight expected margin favours 3 sets. Margin evidence points OPPOSITE the calibrated number.
  Handicap B -1.5 at 1.82: sim 61.8 pct vs 56.2 pct = +5.6 pct. But Shelton wins TIGHT/LONG not by blowouts (4-6 6-4 4-6 yesterday; grinder scoreline distribution), contradicts a -1.5 cover. Also self-contradiction guard: Shelton carries the fatigue haircut for the WIN, so cannot be staked to cover -1.5.

GATES (best candidate: Total Under 24.5)
  G1 edge-origin: PASS - edge from sim distribution, not fatigue/narrative. (ML A edge 0.6 pct independently fails the bar.)
  G2 consensus:   PASS (stake-tier only) - sim/ELO/ML broadly agree on a competitive Shelton win; no independent hard evidence for a full tier.
  G3 fatal-risk:  FAIL - margin bet with a self-negating thesis: the +12.7 pct Under rests entirely on the -3.0 calibration while the RAW sim (25.1) AND the style/scoreline read (two big servers, Shelton tiebreak-heavy 3-set history) both point OVER. Units never buy back a negating risk on a margin bet.

VERDICT: PASS. Models agree with the market on the winner; the ML edge (0.6 pct) is below bar and ELO sits below market. The only nominal edges (Under 24.5, B -1.5) rest on sim outputs directly contradicted by the players scoreline/style reads and, for the handicap, the fatigue self-contradiction guard. No coherent, convergent edge to stake.
