Session 51: Complete Team Hub (2234 tests)

Research-depth team view: /team/[abbr] with roster, archetypes, stats, props.

- Team API: mlbStatsAdapter.getTeams/resolveTeam/getTeamRoster (statsapi, abbr→id
  + active roster, cached). teamService.getTeamHub assembles roster → per-player
  season stats (bounded concurrency) + archetype (snapshot grade or classify) +
  tonight's graded props from grades:{sport}; whole hub cached 15min. MLB real;
  NBA/WNBA graceful snapshot roster. GET /api/team/:abbr (404 unknown) + proxy.
- Team Hub page: server page.tsx (generateMetadata) + TeamHub client — header,
  sort (archetype/graded/A-Z), archetype filter chips, roster rows (archetype +
  player link + position + stats + graded props + parlay "+"), "No active props"
  greyed state, loading/error.
- Game cards: team abbreviations are now TeamLinks → /team/:abbr?sport= (green
  hover, stops propagation). Team Hub has "← Back to Slate".

Backend 2215 -> 2234 tests (+19), 190 suites. Web build clean (exit 0).

 ## Current Phase
-SHIP BUILD v50.0 — Parlay Lab: correlation-aware combined grading, live slip,
-"+" on every graded prop, tier-gated panel. The Desk-tier differentiator.
+SHIP BUILD v51.0 — Team Hub: /team/[abbr] roster with archetypes, season stats,
+graded props; clickable team abbrs on every game card. Research depth.
+
+## Session 51 (2026-06-19) — SHIPPED ✅ TEAM HUB
+
+Backend 2215 → **2234 tests** (+19), 190 suites. Web build clean (exit 0).
+New routes: `/team/[abbr]`, `/api/team/[abbr]`.
+
+### Phase 1 — team data API
+- `mlbStatsAdapter` gained `getTeams()` / `resolveTeam(abbr)` (statsapi
+  `/teams?sportId=1`, cached 24h, abbr→id) + `getTeamRoster(teamId)` (active
+  roster, cached 6h).
+- `src/services/teamService.js getTeamHub(sport, abbr)` assembles the hub:
+  resolve team → roster → per-player season stats (bounded concurrency 8, reuses
+  playerIntelService mappers) → archetype (from the snapshot grade, else
+  classify) → tonight's graded props (from `grades:{sport}`). Whole result cached
+  15 min. MLB = real; NBA/WNBA = a snapshot-built partial roster (graceful note).
+- `GET /api/team/:abbr` (public, 404 on unknown MLB team) + Next proxy.
+
+### Phase 2 — Team Hub page
+`team/[abbr]/page.tsx` (server, `generateMetadata`) + `TeamHub.tsx` (client):
+team header + sport badge, sort (archetype / graded / A–Z), archetype filter
+chips, roster rows (archetype badge + player link + position + horizontal stats
++ graded props with grade badges + parlay "+"), "No active props" greyed state,
+loading/error states.
+
+### Phase 3 — game card team links + back nav
+`vyndr/GameCard` team abbreviations are now `TeamLink`s → `/team/:abbr?sport=`
+(green hover, stops propagation from the open-game handler). Team Hub has
+"← Back to Slate".
