fix(lan-client): swap P3/P4 grid positions for clockwise turn order

Swapped CSS grid-area, zone-row anchoring, commander-row anchoring,
label corners, and life-panel positions for .p3/.p4 so the turn
sequence P1→P2→P3→P4 reads clockwise around the battlefield.
Also added PLAYER_INDEX_TO_QUADRANT lookup in player-panels.js.

-## Quick Start (Windows)
+---
 
-**Prerequisites:** Java 17+, Python 3.10+, Maven 3.8+, [Forge](https://github.com/Card-Forge/forge) built at `D:\ForgeCommander\forge-repo`
+## Features
+
+### Simulation Engines
+
+| Engine | Description | Speed |
+|---|---|---|
+| **Forge** | Rules-complete Java engine — handles the stack, instants, triggered abilities, and all Commander rules. Each game spawns a JVM subprocess. | ~0.04 sims/sec (single-threaded) |
+| **Monte Carlo** | Headless Python engine — models combat keywords (flying, trample, deathtouch, lifelink, menace, reach, haste), summoning sickness, tapped state, commander zone, multiplayer targeting, and board wipes. No JVM required. | Thousands of games in minutes |
+
+Both engines feed structured results into the same ML pipeline.
+
+### Deck Builder
+
+The `POST /api/deck-builder/build` endpoint runs a 7-step pipeline:
+
+1. Resolve commander via Scryfall
+2. Fetch EDHrec recommendations
+3. Fetch Scryfall candidates by category (ramp, removal, draw, lands)
+4. Ollama suggests synergy/protection/wincon cards — **simulation insights injected here**
+5. Filter by color identity, collection, and ban list
+6. Ollama enforces ratios (trim/expand to 99) — **simulation insights injected here**
+7. Assemble final deck with smart substitution (guarantees 99-card output)
+
+### AI Coach
+
+LLM-powered coaching with two modes:
+
+- **Full Session** — Deep analysis including removal coverage, ramp quality, draw engine profiling, win conditions, anti-synergy detection, pod meta evaluation, and tempo assessment
+- **Quick Digest** — Fast ~5-second summary for rapid feedback
+
+Coaching prompts are enriched with semantically relevant cards from the ChromaDB RAG store (15 cards for full sessions, 8 for quick digests). Supports both Anthropic Claude and local Ollama models with streaming responses.
+
+### RAG Card Knowledge
+
+- **SQLite FTS5** bulk card database from Scryfall data
+- **ChromaDB** vector index with natural-language card embeddings
+- Automatic staleness monitoring (checks every 6 hours, auto-rebuilds if >14 days old)
+- Graceful fallback — RAG failures never block coaching or deck building
+
+### ML Training Pipeline
+
+```
+Overnight sims → decisions_*.jsonl
+       ↓
+update_weights.py → learned_weights.json (feeds deck builder)
+       ↓
+/api/ml/train → neural net training on decision dataset
+       ↓
+/api/policy/decide → ML policy serves AI decisions in live games
+```
+
+- **Outcome-weighted RL** nudges card scoring weights from game results
+- **Neural net** trains on the full decision log dataset
+- **Distillation loop** — self-play → collect data → retrain → repeat
+- **ELO tracking** and model tournaments for comparing AI versions
+- Weights clamped to `[-20.0, 20.0]`, stored in `learned_weights.json`
+
+### Win Condition Tracking
+
+Games are classified by win type — not just "Combat" vs "Other":
+
+- **Combat** — standard creature damage wins
+- **Combo** — Approach of the Second Sun, Felidar Sovereign, Happily Ever After, and 30+ known alternate-win cards
+- **Drain** — life drain effects
+- **Mill** — library depletion
+- **Poison** — infect/poison counter wins
+
+Draw games (timeout) are analyzed separately with per-player life-at-timeout snapshots and likely cause identification.
+
+### LAN Battlefield Client
+
+Browser-based 4-player Commander game at `/lan`:
+
+- **AI Bridge** — REST + WebSocket connectivity with ML policy decisions as Priority 1 (falls back to local heuristic AI)
+- **Deck System** — 3-tab selector: Precons (163 decks, grouped by set), EDHREC search, and custom deck import
+- **Player Panels** — Life counters, commander damage bars, poison/energy/experience/rad counters, emblem management
+- **Backend Detection** — Auto-detects the Commander AI Lab backend; works offline with local precon data
+
+### Unity Client
+
+Full Unity application (URP, .NET Standard 2.1) with:
+
+- **Battleground Scene** — 4-seat layout with rotated perspectives, life/poison/commander damage widgets, phase tracker, turn order bar
+- **Card System** — Hand, battlefield, graveyard, exile zones with card art, tapped rotation, face-down state, summoning sickness indicators
+- **Stack & Mana** — LIFO stack display and 6-pip mana pool
+- **Lobby System** — Configure 4 seats (human/AI), POST to backend, WebSocket game state sync
+- **Elimination** — Grayscale shader overlay on eliminated players
+- **Token System** — Create, tap, add counters, delete tokens
+- **Cross-Platform** — Windows, WebGL, Android, iOS build targets
+- **Scenes** — MainMenu, Collection, DeckBuilder, DeckGenerator, Simulator, Coach, Scanner, Training, Precon, Battleground
+
+### Card Scanner
+
+OCR pipeline for physical Magic cards using the Ximilar API. Scan cards from photos and match them to the Scryfall database.

 ## Known Limitations
 
-- **Monte Carlo engine** — no stack, no instants, no continuous type changes (animated lands don't attack)
-- **Forge engine** — each game spawns a new JVM (~2-3s overhead), ~0.04 sims/sec single-threaded
-- **Forge winner life total** not captured (quiet mode only reports losers)
-- **Deck builder** — Ollama suggestions are only as good as the local model; `qwen2.5:7b` works well

+## Dual-Brain AI Decision Flow
+
+This is the **core feature** of Commander-AI-Lab. Every AI player decision runs through this pipeline:
+
+```
+Forge emits GameStateDTO (JSON)
+  └─► FastAPI detects active player is AI
+        └─► select_brain(phase, stack_size)
+              ├─ DeepSeek-R1-14B  → combat, stack decisions, removal
+              └─ GPT-OSS-20B      → main phase, ramp, card advantage
+                    └─► ChromaDB.query(player_deck_cards, top_k=5)
+                          └─► build_prompt(state, rag_context, personality)
+                                └─► LLM.generate(prompt)
+                                      └─► parse_action_json(response)
+                                            ├─ validate vs legal_actions[]
+                                            ├─ log to ai_decisions.jsonl
+                                            └─► Forge stdin ← chosen action
+```

+
+## Phase 0 — Local Card Image Cache
+
+**Build this first.** Every downstream system depends on local art URLs.
+
+### Step 1 — Bulk Download (`scripts/download_card_images.py`)
+
+```python
+import requests, json, os
+from pathlib import Path
+from tqdm import tqdm
+
+BULK_URL  = "https://api.scryfall.com/bulk-data/default-cards"
+IMAGE_DIR = Path("static/card-images")
+IMAGE_DIR.mkdir(parents=True, exist_ok=True)
+
+def download_images():
+    # Get bulk data URL
+    meta = requests.get(BULK_URL).json()
+    cards = requests.get(meta["download_uri"], stream=True).json()
+
+    for card in tqdm(cards, desc="Downloading card images"):
+        image_uris = card.get("image_uris") or {}
+        url = image_uris.get("normal")
+        if not url:
+            continue  # skip DFCs without top-level image_uris
+
+        safe_name = card["name"].replace("/", "_").replace(" ", "_")
+        set_code  = card.get("set", "unknown")
+        filename  = IMAGE_DIR / set_code / f"{safe_name}_{card['collector_number']}.jpg"
+        filename.parent.mkdir(parents=True, exist_ok=True)
+
+        if filename.exists():
+            continue  # already cached
+
+        img_data = requests.get(url, timeout=10).content
+        filename.write_bytes(img_data)
+
+if __name__ == "__main__":
+    download_images()
+```
+
+### Step 2 — Build SQLite Index (`scripts/build_image_index.py`)
+
+```python
+import sqlite3
+from pathlib import Path
+
+IMAGE_DIR = Path("static/card-images")
+DB_PATH   = Path("data/card_images.db")
+DB_PATH.parent.mkdir(exist_ok=True)
+
+def build_index():
+    conn = sqlite3.connect(DB_PATH)
+    conn.execute("""

+    conn.commit()
+    conn.close()
+
+if __name__ == "__main__":
+    build_index()
+```
+
+### Step 3 — Card Enricher (`api/card_enricher.py`)
+
+```python
+import sqlite3
+from pathlib import Path
+
+DB_PATH    = Path("data/card_images.db")
+STATIC_URL = "http://localhost:8000/static/card-images"
+
+def enrich_card(card: dict) -> dict:
+    """Inject local art_url into every CardDTO before sending to Unity."""
+    conn   = sqlite3.connect(DB_PATH)
+    cursor = conn.execute("SELECT path FROM card_images WHERE name = ?", (card["name"],))
+    row    = cursor.fetchone()
+    conn.close()
+    if row:
+        relative = Path(row[0]).relative_to("static/card-images")
+        card["art_url"] = f"{STATIC_URL}/{relative}"
+    else:
+        card["art_url"] = f"{STATIC_URL}/card_back.jpg"
+    return card
+```
+
+### Step 4 — FastAPI Static Mount (`main.py` addition)
+
+```python
+from fastapi.staticfiles import StaticFiles
+app.mount("/static/card-images", StaticFiles(directory="static/card-images"), name="card-images")
+```

+## Phase 4 — Commander Zone UIs
+
+### Zone Definitions per Player
+
+| Zone Panel | Content | Notes |
+|---|---|---|
+| `LIBRARY` | Count only | Click → draw/look at top |
+| `GRAVEYARD` | Scrollable card list | Full card art on hover |
+| `EXILE` | Scrollable card list | Includes face-down indicators |
+| `HAND` | Wide panel, card art | Hidden to opponents |
+| `COMMAND` | Commander card(s) | Shows commander tax counter |
+| `BATTLEFIELD` | Open grid | Tapped/untapped state, counters |
+
+### Commander-Specific UI Elements
+
+```csharp
+public class CommanderZoneUI : MonoBehaviour
+{
+    [SerializeField] private Text taxCounter;      // "Tax: +{2N}"
+    [SerializeField] private RawImage commanderArt;
+    [SerializeField] private Text commanderDamageDealt; // per opponent
+
+    public void Refresh(PlayerDTO player)
+    {
+        int tax = player.CommanderTax;
+        taxCounter.text = tax > 0 ? $"+{tax * 2}" : "";
+
+        if (player.CommandZone.Count > 0)
+            StartCoroutine(CardImageLoader.LoadCardArt(
+                player.CommandZone[0].ArtUrl, commanderArt));
+    }
+}
+```
+
+---
+
+## Phase 5 — Commander Rules Validation Layer
+
+Forge handles all rules natively. FastAPI validates the AI response is within the legal actions list Forge returns — no custom rules code needed in Python or Unity.
+
+Key Commander rules confirmed handled by Forge headless:
+- **Commander Tax** — +2 generic per previous cast from command zone
+- **21 Commander Damage** — tracked per attacker/defender pair
+- **40 Starting Life**
+- **Zone Redirect** — commander goes to command zone instead of graveyard/exile (player choice)
+- **Color Identity** — deck validation at game start
+- **Singleton** — deck validation at game start
+
+---
+
+## Phase 6 — AI Decision Logging & PPO Pipeline
+
+Every AI decision written to `logs/ai_decisions.jsonl`:
+
+```json
+{
+  "timestamp": 1743520800.123,
+  "player_id": "player_2",
+  "brain": "deepseek-r1:14b",
+  "personality": "aggro_beatdown",
+  "phase": "declare_attackers",
+  "action": {"action": "attack", "card_id": "c_042", "targets": ["player_1"], "reasoning": "Open attack, no blockers visible"},
+  "latency_ms": 847
+}
+```
+
+This log becomes the **supervised learning dataset** for the next PPO training iteration. Each (state, action) pair from winning games is a positive training example.

+| **3** | Unity TCGEngine project setup + WebSocket GameNetworkManager | 3–4 days |
+| **4** | PlayerAreaUI + ZonePanels + CardImageLoader + board layout | 3–4 days |
+| **5** | Commander zone UI (tax counter, commander damage, zone redirect) | 1–2 days |
+| **6** | AI decision logging + end-to-end game loop test | 1–2 days |
+
+**Total estimated: ~3 weeks to first playable Commander game with live AI opponents.**
+
+---
+
+## Key Design Decisions
+
+| Decision | Rationale |
+|---|---|
+| Forge = rules authority | Forge already handles all Commander rules natively. No custom rules code. |
+| TCGEngine = dumb renderer | All game logic lives in Forge. Unity only renders state it receives. |
+| FastAPI = hub | Bridges Forge ↔ Unity ↔ AI. Single point of truth. |
+| Dual-brain routing | DeepSeek-R1 excels at analytical/math decisions; GPT-OSS at strategic sequencing. |
+| ChromaDB scoped per player | RAG context relevant to the active player's deck, not global card knowledge. |
+| Personality persists per game | Consistent playstyle per AI across all 4 players per session. |
+| Local image cache | Eliminates network latency for card art. ~2GB one-time download. |
+| ai_decisions.jsonl | Every AI decision is a future PPO training sample. |

+Forge IPC flow
+--------------
+  1. POST /api/game/start
+       - Validates seats, resolves deck names
+       - Picks a playstyle per AI seat from seat_type (e.g. "AI Aggro" -> "aggro")
+       - Calls run_batch_subprocess(num_games=1, use_learned_policy=True, ...)
+         which builds the Java command with --policy <style> --policyServer http://localhost:8080
+         and spawns the Forge JAR in a background thread
+       - Returns game_id + ws_url immediately (non-blocking)
+  2. Forge JAR (once launched) calls POST /api/policy/decide on every AI decision
+  3. Human actions are queued via POST /api/game/action and drained by
+     GET /api/game/{game_id}/actions (polled by the Forge IPC loop inside the JAR)
+  4. GET /api/game/{game_id}/status returns live log tail + completion state

+Analyses draw-game snapshots captured by forge_runner._run_process_blocking.
+
+A "draw game" is any game that hit the Forge per-game wall-clock timeout

+
+This module:
+  1. Parses those lines out of the log into DrawGameSnapshot objects.
+  2. Aggregates them to identify which deck most often leads at timeout.
+  3. Exposes a summary dict suitable for embedding in the batch result JSON.

+/**
+ * PolicyControllerAi — Phase 2 live-game controller that routes AI decisions
+ * through the Python policy server instead of Forge's built-in heuristics.
+ *
+ * <h2>Architecture</h2>
+ * <pre>
+ *   Forge game loop
+ *       └─ player.getController()            → PolicyControllerAi
+ *               └─ brains (PolicyAiController extends AiController)
+ *                       └─ chooseSpellAbilityToPlay()
+ *                               ├─ buildGameStateJson()
+ *                               ├─ policyClient.decide(stateJson)   → macro-action
+ *                               ├─ mapMacroActionToSpellAbility()   → SpellAbility
+ *                               └─ super.chooseSpellAbilityToPlay() (fallback)
+ * </pre>
+ *
+ * <h2>Two-class design</h2>
+ * <ul>
+ *   <li>{@link PolicyAiController} — inner subclass of {@link AiController}
+ *       that overrides {@code chooseSpellAbilityToPlay()}.  This is the
+ *       intercept point closest to the game loop.</li>
+ *   <li>{@link PolicyControllerAi} — subclass of {@link PlayerControllerAi}
+ *       that swaps Forge's default {@code AiController} for a
+ *       {@code PolicyAiController} and exposes lifecycle helpers
+ *       (game-end reward submission, statistics).</li>
+ * </ul>
+ *
+ * <h2>Decision flow</h2>
+ * <ol>
+ *   <li>Build a rich {@link JsonObject} snapshot of the current game state
+ *       (per-player life/mana/zones, stack, phase, legal actions).</li>
+ *   <li>POST the snapshot to {@code /api/policy/decide} via
+ *       {@link PolicyClient#decide(JsonObject)}.</li>
+ *   <li>Translate the returned macro-action name (e.g. {@code "cast_creature"})
+ *       to a concrete {@link SpellAbility} from the legal action list using
+ *       {@link MacroActionExecutor}'s card-role databases.</li>
+ *   <li>If the server is unreachable or no mapping succeeds, fall back to
+ *       {@link AiController#chooseSpellAbilityToPlay()} transparently.</li>
+ *   <li>Log every decision (policy or fallback) for training data collection.</li>
+ * </ol>
+ *
+ * <h2>Fallback guarantee</h2>
+ * Every code path in {@link PolicyAiController#chooseSpellAbilityToPlay()}
+ * is wrapped in a broad {@code try/catch}.  Any unexpected exception causes
+ * an immediate delegate to the parent Forge AI so the game continues safely.
+ *
+ * <h2>Usage</h2>
+ * <pre>{@code
+ * PolicyClient client = new PolicyClient("http://localhost:8080");
+ * client.connect();
+ *
+ * // When Forge constructs the AI player's controller:
+ * PolicyControllerAi controller = new PolicyControllerAi(game, player, lobbyPlayer, client);
+ *
+ * // After the game ends:
+ * controller.onGameEnd(won ? 1.0 : -1.0);
+ * }</pre>
+ *
+ * @see PolicyClient
+ * @see PolicyAiController
+ * @see MacroActionExecutor
+ * @since Phase 2.1 — Issue #83
