Session 44: Make it visible — VYNDR archetype names, grade intel, schedule fix, landing page (2061 tests)

Frontend + wiring only. Wires existing backend into the pages users see.

- VYNDR Original archetype rename (41) across archetypeService.js + lib/
  archetypes.js + ArchetypeBadge, each keeping legacyName (resolves stale data).
  Judge -> BOMBER. Old POWER PULL slot -> WHIFF strikeout-artist pitcher.
- BACKEND_HANDOFF.md: canonical frontend<->backend data contract.
- Grade card intel: scan/page.tsx now forwards the engine's intel fields
  (season_avg/form/usage/matchup_grade/archetype/...) into mapScanToGradeResult
  -> STAT CONTEXT + VYNDR INTELLIGENCE sections populate. The chain already
  preserved them (tierGating + /api/scan spread); the page was dropping them.
- Schedule freshness: slateAdapter.isRelevantGame drops completed games >24h
  old; Slate.filteredGames applies it. (TTL already 60s.)
- Landing: Features.tsx rewritten to user-facing copy (no Point-biserial/Zone
  14/ABS/Phi-coefficient).
- Depth chart Next proxies added (/api/stats/lineup|depth|cascade) - were 404.
- GameCard swap DEFERRED (Kev): legacy on-demand card stays as a bridge until
  the snapshot pipeline populates the grades cache; vyndr/GameCard swaps in then.

Backend 2045 -> 2061 tests (+16), 167 suites. Web build clean (exit 0).

 ## Current Phase
-SHIP BUILD v43.0 — Data pipeline wiring + P0 audit fixes + depth chart
-foundation. The Session-42 Player Intelligence architecture now flows REAL data.
+SHIP BUILD v44.0 — Make it visible: VYNDR Original archetype names, grade-card
+intel wiring, stale-game filtering, landing copy, depth proxies. Frontend +
+wiring only (no new backend services).
+
+## Session 44 (2026-06-18) — SHIPPED ✅ MAKE IT VISIBLE
+
+Wired existing backend work into the pages users see + renamed archetypes to
+VYNDR Originals. Backend 2045 → **2061 tests** (+16), 167 suites. Web build clean
+(exit 0). `BACKEND_HANDOFF.md` added as the canonical data contract.
+
+### VYNDR Original archetype rename (proprietary names)
+All 41 archetypes renamed in `archetypeService.js` + `lib/archetypes.js` +
+`ArchetypeBadge`, each keeping `legacyName`/`legacy` (never displayed; resolves
+for stale data). NBA: TORCH, CONDUCTOR, FORTRESS, ARTILLERY, SURGE, DUAL THREAT,
+CONNECTOR, FASTBREAK, PAINT BOSS, LOCKDOWN, SWITCHBOARD, ARCHITECT, PISTON,
+SENTINEL, IGNITER. WNBA-unique: DISTRIBUTOR, SHIELD, RANGE, SPARK, ANCHOR. MLB:
+BOMBER, BRUSH, DRIVER, ALPHA, WHIFF, GHOST, HYBRID, FLEX, WORKHORSE, CATALYST,
+MIRROR, HAMMER, SINKER, BRIDGE, SWITCH. Soccer: FINISHER, MAESTRO, TOWER, MOTOR,
+BLADE, WALL. **MLB note:** the old taxonomy had two power hitters (POWER
+PULL/POWER SLUGGER) but the new set has one power name (BOMBER), so BOMBER now
+fires for any high-HR bat (Judge → BOMBER per the audit checklist) and the freed
+slot became a real WHIFF strikeout-artist pitcher (improves pitcher coverage).
+`getArchetype`/`archetypeInfo` resolve legacy names → VYNDR Originals.
+
+### Phase 2 — grade-card intel now populates (the real bug)
+The chain engine→tierGating→/api/scan proxy already PRESERVED the intel fields
+(all spread `...result`/`...data`). The ONE broken link: `scan/page.tsx` called
+`mapScanToGradeResult` with a hardcoded field subset and DROPPED season_avg/
+form/usage/matchup_grade/etc. Now forwards them (+ extended `ScanResponse`), so
+STAT CONTEXT + VYNDR INTELLIGENCE sections light up on a real MLB grade.
+
+### Phase 3 — stale-game filtering
+`slateAdapter.isRelevantGame(game, now)`: upcoming/live always show; a COMPLETED
+game is dropped once >24h old (no more 5-day-old FINALs). Applied in `Slate`'s
+`filteredGames`. Schedule TTL was already 60s (≤30min) — no change.
+
+### Phase 4 — landing copy
+`Features.tsx` rewritten: no more "Point-biserial", "Zone 14", "ABS
+intelligence", "Auto-calibrating", "Phi-coefficient". User-facing benefit copy
+(Player DNA archetypes / Self-improving model / Lineup intel before tip-off /
+Deep pitcher-batter matchups).
+
+### Phase 5 — depth chart proxies (404 fix)
+Added the missing Next proxies `/api/stats/lineup/[team]`, `/depth/[team]`,
+`/cascade/[player]` → return JSON, not 404.
+
+### Phase 1 — GameCard swap DEFERRED (decision: Kev)
+The live Slate keeps the legacy "Read"/on-demand grade card as a **temporary
+bridge**. The vyndr/GameCard swap lands WITH the snapshot pipeline (next
+session): the on-demand "Read" model is being retired for a pre-graded snapshot
+model (full slate graded at scheduled intervals, grades locked to the line), and
+the new card is designed for that. Swapping now would remove grading + show blank
+cards (grades cache unpopulated). BookChip brand colors already render in the
+legacy card (S43).
