Correlation-aware combined parlay grading — the Desk-tier differentiator.
- Correlation model (parlayService.js, added to S28 funcs): correlationScore
(game-aware 0.7/0.4/0.2/0.0), combinedGrade (avg penalized by avgCorr*0.5),
estimatedPayout (fair-odds product * (1-avgCorr) discount), correlationWarning,
gradeParlay.
- POST /api/parlay/grade (public, 2-6 legs) -> {combined,correlation,payout,legs}.
Fixed the Next proxy (was forwarding to /api/scan/parlay).
- ParlayContext: legs gained team/game/archetype; tier-aware maxLegs; auto-grades
the slip (debounced) when legs>=2 -> live combined/correlation/payout; hasLeg/
legKey/atCap.
- "+" button on every graded prop: StatStrip onAddLeg/isLegActive, wired by
vyndr/GameCard via useParlay (builds leg w/ team + game). GradeResultCard feeds
the same context from the scan page.
- ParlayPanel (replaces legacy ParlayTray): bottom slide-up w/ legs, combined
grade, correlation warning, est payout, CLEAR ALL + floating leg-count badge.
Tier-gated: free 2 legs (payout blurred -> Desk upsell), Analyst 4, Desk 6.
Backend 2185 -> 2215 tests (+30), 187 suites. Web build clean (exit 0).
