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).

 ## Current Phase

-self-hosted fonts). Design conversion (33–39) remains COMPLETE.
+SHIP BUILD v42.0 — Player Intelligence System (archetypes, stat strips, player
+profile, enhanced cards, settings, stats explorer). Built from the Claude Design
+"VYNDR Player Intelligence" bundle.
+
+## Session 42 (2026-06-18) — SHIPPED ✅ PLAYER INTELLIGENCE SYSTEM
+
+Built the full Player Intelligence design bundle (10 sections; the 6 spec items
++ extras). Backend 1940 → **2011 tests** (+71), 157 suites. Web build clean
+(exit 0). Both gates green.
+
+### What shipped (by design section)
+1. **Archetype system** — `src/services/archetypeService.js`: 41 archetypes
+   (15 NBA + 5 WNBA-unique + 15 MLB + 6 soccer), each with tag/color/glyph/
+   description/propDNA/education. `classify(sport, stats)` returns PRIMARY +
+   optional SECONDARY + a normalized `blend`. Visual map mirrored in
+   `web/src/lib/archetypes.js` (CommonJS, colors verified == backend).
+   Components: `ArchetypeBadge` (full/ghost/tint + glyphs), `ArchetypeBlend`
+   (the production-DNA bar).
+2. **StatStrip** — `components/vyndr/StatStrip.tsx`, compact + expanded. The
+   player name appears ONCE; stats flow horizontally (JetBrains Mono); props
+   inline with GradeBadge; `onPlayerClick` → profile.
+3. **Stats API + Player Profile** — extended `src/routes/stats.js` with
+   `/player/:name`, `/leaders`, `/game/:id` (rate-limited 60/min). Aggregation
+   in `src/services/playerIntelService.js` (sanitizes the name param; reads
+   grades:{sport} cache for props; graceful on cold caches). Page:
+   `app/player/[name]/page.tsx` — all 9 design sections (hero+DNA blend, injury,
+   prop DNA, VYNDR intelligence, active props, season, last 10, splits, grade
+   history). Next proxies under `app/api/stats/player|leaders`.
+4. **Enhanced game cards + Grade Result** — `vyndr/GameCard` gained optional
+   MLB starting pitchers + player-grouped `playerStrips` (StatStrip, name once);
+   `GradeResultCard` gained archetype strip + STAT CONTEXT + VYNDR INTELLIGENCE
+   (all optional/self-hiding; populated by `gradeAdapter.buildIntelFields`).
+   Header player name now links to the profile.
+5. **Settings page** — `app/settings/page.tsx` REPLACES the S41 redirect:
+   account (tier from useAuth), subscription, notifications, display (→ Prefs
+   modal via `window.__prefs`), responsible play, danger zone (delete button
+   gated on typing DELETE exactly). LINKS to `/settings/security` — does NOT
+   replace the real MFA page. + `BookChip` component (`lib/books.js`).
+6. **Stats Explorer (bonus, design §07)** — `app/explore/page.tsx`: tonight's
+   league leaderboard from the real `/api/stats/leaders`, sport tabs, search,
+   rows → player profile. Added to the Nav MORE menu (Explore + Settings→/settings).
+
+### Player-name links wired
+Game cards, Grade Result header, Stats Explorer rows, profile active props — all
+route to `/player/:name?sport=` via `lib/playerHref.js`.
+
+### Deferred (design sections present but NOT built this session)
+Team Hub (§09), Offseason Intel (§08), and the Slate redesign (§10), plus the
+Stats Explorer sub-panels (hit-rate trends, head-to-head, market-vs-VYNDR,
+matchup ratings). These need historical / projection / depth-chart data
+pipelines that don't exist yet — they belong with the Session-43 snapshot
+pipeline. The archetype + leaders + profile foundations they'd build on are now
+in place.

+The Chrome audit's P0 list only. No features. Backend 1907 → **1940 tests**
