builtbykev f72f063e6f Suppress rare-event 0.5 unders (juiced, no-edge) — config-driven grade + board fix 
Betting-logic audit: the CONSENSUS-vs-MODEL board flooded with fake reads like
"DOUBLES u0.5 · MODEL 0.2 · +edge" — the juiced under side of rare counting-stat
markets (doubles/triples/HR/SB), which is never a takeable edge and violates the
no-unders-default doctrine.

Report finding (item 3/4): the doubles projection is REAL per-player, not a flat
fallback — 'doubles' maps to a real game-log field (MLB_LOG_FIELD doubles→
doubles) and the live values varied (0.03/0.16/0.2/0.22). So no projection-gate
refusal for fakeness; the problem is purely structural (a rare event's real
projection always sits below a 0.5 line, so the under always "wins").

Fix (config-driven — src/config/rareEventMarkets.js, tunable stat list + line
threshold):
- Grade layer (analyzeViaEngine1): a rare-event UNDER at ≤0.5 is always REFUSED
  (grade null + suppressed flag/reason). A rare-event OVER at ≤0.5 is refused
  UNLESS the model genuinely projects the event above the line — because a
  0.2-over-0.5 carries the SAME |edge| as the suppressed under and would just
  take its rank on the board. The over grades normally once projection > line.
- Board layer (marketBreadth.collectBreadth): drops null-model rows so a
  suppressed/ungraded prop can't rank a "MODEL —" placeholder onto the board.

10 suppression tests + config locks; also fixed a settingsPage book assertion
left over from the ESPN→theScore swap. Suite 274/3289 green, web build exit 0.

builtbykev 8bc79f3c38 Session 42: Player Intelligence System — archetypes, stat strips, player profile, enhanced cards (2011 tests) 
Built from the Claude Design "VYNDR Player Intelligence" bundle (10 sections).

- Archetypes: src/services/archetypeService.js — 41 archetypes (15 NBA / 5
  WNBA-unique / 15 MLB / 6 soccer), classify -> primary+secondary+blend.
  Frontend visual map web/src/lib/archetypes.js (colors verified == backend).
  ArchetypeBadge (full/ghost/tint + glyphs) + ArchetypeBlend (DNA bar).
- StatStrip (compact/expanded): player name once, horizontal mono stats,
  inline GradeBadge props, onPlayerClick -> profile.
- Stats API: extended src/routes/stats.js with /player/:name, /leaders,
  /game/:id (rate-limited). Aggregation in playerIntelService.js (sanitizes
  name param; grades cache; graceful on cold cache). Next proxies added.
- Player Profile /player/[name]: all 9 design sections, graceful empty states.
- Enhanced GameCard (MLB pitchers + player-grouped StatStrips) + GradeResultCard
  (archetype strip + stat context + VYNDR intelligence, optional/self-hiding via
  gradeAdapter.buildIntelFields). Player-name links wired everywhere.
- Settings page replaces the S41 redirect (account/subscription/notifications/
  display/responsible-play/danger-zone with DELETE-gated delete). LINKS to the
  real /settings/security MFA page — does not replace it. + BookChip.
- Bonus: Stats Explorer /explore (real /api/stats/leaders leaderboard); added
  Explore + Settings to Nav MORE.

Deferred (need data pipelines, Session 43): Team Hub, Offseason Intel, Slate
redesign, Stats Explorer sub-panels.

Backend 1940 -> 2011 tests (+71), 157 suites. Web build clean (exit 0).
