The pricing Desk showcase hardcoded an alt-line ladder (1.5 A +7.1% / 2.5 A+
+11.4% / 4.5 C -3.8%), QUARTER-KELLY 2.4%, and PARLAY φ 0.34 — a mocked demo
selling something we weren't proving.
- deskShowcaseService reads the pre-graded snapshot for a real A/B prop's
alt-line ladder (prefers the one with the most grade variation — the most
compelling real example). Edge per rung shows only when it's a plausible
market value; the inflated (model-line)/line artifact on small lines is
guarded to "—" rather than shown as a fake +91%.
- PARLAY φ is now REAL: the model's same-team correlation (0.34, mirroring the
frontend parlayMath team constant) computed for TWO REAL same-team legs,
named. No real same-team pair on the board → the tile hides, never an
invented number.
- QUARTER-KELLY tile is REMOVED: the snapshot has no odds, so a real
quarter-Kelly % can't be computed here — a fabricated 2.4% is worse than
nothing. Kelly stays a real in-app Desk feature; the showcase just doesn't
fake it.
- DeskShowcase is now a client component fetching /api/desk-showcase; when the
board has no real ladder the whole visuals column hides (real-or-hidden, same
law as the hero). The pitch copy is unchanged.
