Session 43: Data pipeline + audit fixes + depth chart foundation (2045 tests)

P0 fixes + wiring real data into the S42 Player Intelligence architecture.

- P0 dropdown z-index: the nav's backdrop-filter stacking context let the
  Ticker/HeartbeatBar paint over the avatar/More dropdowns and eat clicks.
  nav now position:relative zIndex:2; menus zIndex:100. Avatar Settings ->
  /settings.
- Real MLB stats: mlbStatsAdapter.searchPlayer + getPlayerStats (name->id->
  season+gamelog). playerIntelService.resolvePlayerStats normalizes into the
  archetype classifier; getPlayerIntel returns found:true + real season +
  archetype classified from real stats. NBA via nbaStatsClient (degrades).
- Game cards: slateAdapter.groupPropsByPlayer (playerStrips, name once) +
  mapPitchers (MLB probables), folded into mapScheduleToGameCards. Legacy
  GameCard line grid renders BookChip (brand colors) not grey text.
- Grade card intel: analyzeViaEngine1.buildIntelFields computes stat-context +
  form/usage/matchup/rest from the existing feature vector (zero extra I/O);
  gradeAdapter lights up the card sections. Archetype deferred (needs season
  line at grade time).
- Depth chart foundation: depthChartService (getLineup/getDepthChart/
  getCascadeProjection) + /api/stats/lineup|depth|cascade, graceful + injectable.
- Mobile: player hero name overflow-wrap + 24px on <=640px (was clipping).

Backend 2011 -> 2045 tests (+34), 163 suites. Web build clean (exit 0).

 ## Current Phase
-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.
+SHIP BUILD v43.0 — Data pipeline wiring + P0 audit fixes + depth chart
+foundation. The Session-42 Player Intelligence architecture now flows REAL data.
+
+## Session 43 (2026-06-18) — SHIPPED ✅ DATA PIPELINE + AUDIT FIXES
+
+Post-S42 Chrome audit: architecture renders but no real data flowed (every
+player `found:false`, leaders empty, grade intel hidden) + a P0 dropdown bug.
+Backend 2011 → **2045 tests** (+34), 163 suites. Web build clean (exit 0).
+
+### Phase 1 — P0 bug fixes
+- **Avatar/More dropdown z-index** — the `<nav>` has `backdrop-filter` (a
+  stacking context); `<Ticker>` + `<HeartbeatBar>` render after it as siblings
+  and painted OVER the dropdowns (which overflow below the 60px bar), eating
+  clicks. Fix: `position:relative; zIndex:2` on the nav floats it (and its
+  menus) above those bars; menus also carry `zIndex:100`. Avatar "Settings" →
+  `/settings` (was `/settings/security`). Explore was already in MORE (S42) —
+  the audit "missing" was a deploy cache.
+
+### Phase 2 — real player stats
+- **`mlbStatsAdapter`** gained `searchPlayer(name)` (season player-list lookup,
+  cached 24h) + `getPlayerStats(name)` (resolve id → season + game log, picks
+  pitching/hitting by position). The adapter only had id-keyed methods before.
+- **`playerIntelService.resolvePlayerStats(name, sport)`** normalizes the raw
+  MLB stat object → classifier input + display season rows + last-10 log.
+  `getPlayerIntel` now classifies the archetype from REAL stats and returns
+  `found:true` with real season data. Aaron Judge → POWER PULL, not the
+  empty-stats fallback. NBA/WNBA path wired to `nbaStatsClient` (degrades
+  quietly — the Python nba_api service is usually offline in prod). All
+  adapters injectable for tests; everything still degrades gracefully.
+- **Leaders**: `/api/stats/leaders` + the explore page already share the
+  `grades:{sport}` cache source — no mismatch to fix. Emptiness is data
+  population (the slate must be graded first); the snapshot pipeline (Session
+  44) keeps it warm.
+
+### Phase 3 — game card enhancements
+- `slateAdapter` gained `groupPropsByPlayer` (→ `playerStrips`, name once) +
+  `mapPitchers` (MLB probables → GameCard `pitchers`); both folded into
+  `mapScheduleToGameCards` output (vyndr/GameCard consumes them; legacy ignores
+  the extras). Legacy `GameCard` line grid now renders `BookChip` (brand
+  colors) instead of plain grey book text (the audit's complaint).
+
+### Phase 4 — grade card intelligence
+- `analyzeViaEngine1` attaches stat-context + VYNDR-intelligence fields
+  (`season_avg`/`last10_avg`/`form`/`usage`/`matchup_grade`/`rest`) computed
+  from the EXISTING feature vector — zero extra I/O. `gradeAdapter` maps them in,
+  so the card's STAT CONTEXT + VYNDR INTELLIGENCE sections light up. Archetype
+  is intentionally NOT set here (the per-prop feature vector lacks a multi-stat
+  season line; the archetype strip stays hidden until Session 44 feeds it).
+
+### Phase 5 — depth chart foundation
+- **`src/services/depthChartService.js`**: `getLineup` (MLB probable starter
+  from the schedule), `getDepthChart` (positions from an injected roster),
+  `getCascadeProjection` (usage redistribution weighted by archetype — sponges
+  heaviest). All graceful + injectable. Endpoints: `/api/stats/lineup/:team`,
+  `/depth/:team`, `/cascade/:player`. (Next proxies + UI = Session 45.)
+
+### Phase 6 — mobile + cosmetics
+- Player-profile hero name was clipping ("Wembanyam") at 390px — added
+  `overflow-wrap:anywhere` + a mobile rule (`.player-hero-name` 24px). Font CDN
+  already gone since S41 (next/font).
+
+### Deferred (honest scope)
+- Full live-slate swap to vyndr/GameCard (needs inline grading ported) — the
+  data layer is now ready (`playerStrips`/`pitchers`).
+- Per-player archetype badges on slate cards + grade-card archetype strip — need
+  per-player season lines at grade time (Session 44 snapshot pipeline).
+- Depth chart UI + lineup/minutes projections (Session 45).
