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.

 # Commander AI Lab
 
-Headless batch simulation environment for 3-AI MTG Commander pods.
+A full-stack Magic: The Gathering Commander research platform. Run thousands of simulated games, train neural networks on the outcomes, build decks with AI that learns from simulation data, get LLM-powered coaching, and play live 4-player battles — all from a single unified system.
-Run 100+ games, analyze win rates, and stress-test your decks — all from a web UI or CLI.
+
+---
+
+## Overview
+
+Commander AI Lab connects a rules-complete Forge engine, a fast Monte Carlo simulator, an LLM deck builder, an ML training pipeline, and multiple game clients (web, LAN, Unity) into one closed-loop platform. Simulation results feed back into deck building and AI decision-making, so the system improves the more it plays.
+
+### Key Capabilities
+
+- **Batch Simulation** — Run hundreds or thousands of Commander games unattended using Forge (rules-complete) or a headless Python Monte Carlo engine
+- **ML Training Pipeline** — Reinforcement learning (PPO) trains a neural net on game decision logs; outcome-weighted scoring nudges card weights automatically
+- **AI Deck Builder** — 7-step LLM pipeline (EDHrec → Scryfall → Ollama) with simulation-learned insights injected into prompts
+- **LLM Coach** — Streaming coaching sessions powered by Anthropic Claude or local Ollama models, enriched with RAG-retrieved card knowledge
+- **RAG Card Knowledge** — ChromaDB vector store over 30,000+ Scryfall cards with semantic search and auto-staleness monitoring
+- **LAN Battlefield** — Browser-based 4-player Commander game client with ML-powered AI opponents and precon deck support
+- **Unity Client** — Full Unity application with battleground scene, lobby system, WebSocket game state sync, and cross-platform builds
+- **Card Scanner** — OCR pipeline for physical card recognition via Ximilar API
+- **163 Precon Decks** — Complete preconstructed deck library in `.dck` format

-## Quick Start (Windows)
+---
+
+## 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.

+---
+
+## Overnight AFK Runner
+
+Run batch simulations unattended, then automatically update card weights and train the neural net:
 
-### 5. CLI-only usage (no web server)
 ```powershell
-cd D:\ForgeCommander\forge-repo\forge-gui
+python overnight-run.py                          # default: 11.5h DeepSeek sims
-
+python overnight-run.py --batches 20 --games 50  # fixed batch count
-java -jar "D:\ForgeCommander\commander-ai-lab\target\commander-ai-lab-1.0.0-SNAPSHOT.jar" `
+python overnight-run.py --no-update-weights      # skip weight update
-  --forge-jar "..\forge-gui-desktop\target\forge-gui-desktop-2.0.12-SNAPSHOT-jar-with-dependencies.jar" `
+python overnight-run.py --no-train               # skip neural net training
-  --forge-dir "." `
-  --deck1 "Edgar Markov" `
-  --deck2 "Grimgrin" `
-  --deck3 "Xyris" `
-  --games 100 `
-  --threads 4 `
-  --output results/batch-100.json
 ```
 
-## Scaling Tests
+**What happens after sims complete:**
+1. `update_weights.py` — nudges `learned_weights.json` from decision logs (feeds deck builder)
+2. `/api/ml/train` — trains the neural net on the full decision dataset
 
-### Single-threaded baseline (10 games)
+---
-```powershell
+
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar `
+## Simulation → Deck Builder Feedback Loop
-  --forge-jar "..." --forge-dir "..." `
+
-  --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" `
+```
-  --games 10 --threads 1 --output results/baseline-10.json
+Overnight sims → decisions_*.jsonl
+       ↓
+update_weights.py → learned_weights.json
+       ↓
+sim_insights.py → natural-language insight block
+       ↓
+Ollama prompts (suggest_cards + enforce_deck_ratios)
+       ↓
+Better card recommendations
 ```
 
-### Multi-threaded (10 games, 2 threads)
+When active, `BuildResult.sources_consulted` includes `"sim_weights"`. The loop is a no-op until real sim data exists.
-```powershell
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar `
-  --forge-jar "..." --forge-dir "..." `
-  --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" `
-  --games 10 --threads 2 --output results/mt-10-t2.json
-```
 
-### Scale to 100 games (4 threads)
+---
-```powershell
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar `
-  --forge-jar "..." --forge-dir "..." `
-  --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" `
-  --games 100 --threads 4 --output results/scale-100-t4.json
-```
-
-### Maximum throughput test (100 games, 8 threads)
-```powershell
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar `
-  --forge-jar "..." --forge-dir "..." `
-  --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" `
-  --games 100 --threads 8 --seed 42 --output results/scale-100-t8-seed42.json
-```
-
-### Performance comparison script
-Run different thread counts and compare sims/sec:
-```powershell
-# Baseline: 1 thread
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar --forge-jar "..." --forge-dir "..." --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" --games 20 --threads 1 --seed 42 --output results/perf-t1.json
-
-# 2 threads
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar --forge-jar "..." --forge-dir "..." --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" --games 20 --threads 2 --seed 42 --output results/perf-t2.json
-
-# 4 threads
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar --forge-jar "..." --forge-dir "..." --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" --games 20 --threads 4 --seed 42 --output results/perf-t4.json
-
-# 8 threads
-java -jar target\commander-ai-lab-1.0.0-SNAPSHOT.jar --forge-jar "..." --forge-dir "..." --deck1 "Edgar Markov" --deck2 "Grimgrin" --deck3 "Xyris" --games 20 --threads 8 --seed 42 --output results/perf-t8.json
-```
-
-Then compare the `simsPerSecond` values in each output JSON to see scaling behavior.

+## ML Scripts
 
 ```powershell
-cd D:\ForgeCommander\commander-ai-lab
+# Update card weights from decision logs
-pip install -e .
+python -m ml.scripts.update_weights --min-games 10 --lr 0.05 --dry-run
+
+# Reset weights to defaults
+python -m ml.scripts.update_weights --reset
+
+# Generate synthetic training data
+python ml/scripts/generate_synthetic_data.py
 ```
 
-This installs `commander_ai_lab` as an importable package and registers the `commander-sim` CLI command.

-### Quick smoke test
+## Python Simulator API
-
-```powershell
-python -m commander_ai_lab.lab.experiments
-```
-
-Expected output — a 10-game Monte Carlo run of a sample "Korvold" deck:
-
-```
-══════════════════════════════════════════
-  Commander AI Lab — Experiment Runner
-══════════════════════════════════════════
-
---- Demo: Korvold Aristocrats (10 games) ---
-
-  Win rate:          XX.X%
-  Avg turns:         XX.X
-  Avg damage dealt:  XX.X
-  Avg spells cast:   XX.X
-  Avg creatures:     XX.X
-  Elapsed:           0.02s
-
-  Done.
-```
-
-### Python API
 
 ```python
-from commander_ai_lab.sim.models import Card
-from commander_ai_lab.sim.engine import GameEngine
 from commander_ai_lab.lab.experiments import build_deck, run_simulation
 
-# Build a deck from card names
+deck = build_deck(["Sol Ring", "Cultivate", "Lightning Bolt"] + ["Forest"] * 36)
-deck = build_deck(["Sol Ring", "Cultivate", "Lightning Bolt", "Forest"] + ["Forest"] * 36)
-
-# Monte Carlo simulation (100 games)
 stats = run_simulation(deck, num_games=100, name_a="My Deck")
-print(f"Win rate: {stats['win_rate']:.1%}")
+print(f"Win rate: {stats['win_rate']:.1%}, Avg turns: {stats['avg_turns']:.1f}")
-print(f"Avg turns: {stats['avg_turns']:.1f}")
 ```
 
-Key functions:
+---
-
-| Function | Description |
-|---|---|
-| `build_deck(card_names)` | Create enriched `Card` list from names |
-| `build_deck_from_text(decklist)` | Parse `"1 Sol Ring\n37 Forest"` format |
-| `run_single_game(deck_a, deck_b)` | One game, returns winner/turns/stats |
-| `run_simulation(deck_a, deck_b, n)` | Monte Carlo over `n` games, aggregated stats |
-
-### CLI entry point
-
-After `pip install -e .`:
-
-```powershell
-commander-sim
-```
-
-Runs the same demo as `python -m commander_ai_lab.lab.experiments`.
-
-### How the engine works
-
-1. **Deck enrichment** — `enrich_card()` infers type, CMC, keywords, and power/toughness from card name heuristics when Scryfall data is unavailable.
-2. **AI scoring** — `score_card()` uses weighted categories (removal, ramp, draw, aggro, etc.) to pick the best play each turn.
-3. **Game loop** — Each turn: untap → draw → play lands → cast spells (AI scored) → combat (attack/block decisions) → end step. Full keyword support for flying, trample, deathtouch, lifelink, menace, and reach.
-4. **Monte Carlo** — `run_simulation()` runs N independent games and aggregates win rate, avg turns, damage dealt/received, spells cast, creatures played, removal used, ramp played, cards drawn, and max board size.

-## Frontend Development
+| Layer | Technology |
+|---|---|
+| Backend | Python 3.10+, FastAPI, Uvicorn |
+| Simulation (rules-complete) | Java 17, Maven, Forge |
+| Simulation (fast) | Python Monte Carlo engine |
+| LLM Inference | Ollama (qwen2.5:7b), Anthropic Claude |
+| Vector Store | ChromaDB with all-MiniLM-L6-v2 embeddings |
+| Card Database | SQLite FTS5 (Scryfall bulk data) |
+| ML Training | PyTorch, PPO reinforcement learning |
+| Web Client | HTML/CSS/JS |
+| Unity Client | Unity 2022 LTS, URP, C# |
+| CI/CD | GitHub Actions |
 
-The UI is a React + TypeScript SPA in the `frontend/` directory.
+---
-
-### Dev server (with hot reload)
-```bash
-cd frontend
-npm install
-npm run dev
-```
-Vite proxies `/api` and `/ws` to `localhost:8000`, so start the FastAPI backend first.
-
-### Production build
-```bash
-cd frontend
-npm run build
-```
-FastAPI serves the built assets from `frontend/dist/`.
 
 ## Known Limitations
-- Winner's life total not captured (Forge quiet mode only reports losers)
+
-- Win condition classification is heuristic-based on Forge loss reason strings
+- **Monte Carlo engine** — no stack, no instants, no continuous type-changing effects (animated lands don't attack)
-- Each game spawns a new JVM process (~2-3s overhead per game)
+- **Forge engine** — each game spawns a new JVM (~2–3s overhead); ~0.04 sims/sec single-threaded
-- Max throughput ~0.04 sims/sec single-threaded (Forge sim is CPU-heavy)
+- **Forge** — winner life total not captured in quiet mode (only reports losers)
-- Multithreading spawns parallel subprocesses — throughput scales linearly with threads up to CPU core count
+- **Deck builder** — Ollama suggestions depend on the local model quality; `qwen2.5:7b` works well
+- **LAN client** — EDHREC commander search is a stub (backend-powered, not yet fully wired)

 - Use perArchetypeWinRates to identify which matchup types this deck struggles with and tailor suggestions accordingly.
+- The Sim Insights section shows pre-computed deck-level signals — use these directly in your reasoning.

+- Cards flagged as [LATE CASTER] have avgTurnCast > 6 — consider whether they fit the deck's tempo.
+- Cards flagged as [ISOLATED] have synergyScore in the bottom 3 of the deck — they may not support the gameplan.
+- Archetypes flagged as [WEAK SPOT] in the Archetype Win Rates section are where this deck loses most — prioritize fixes for those matchups.
 - Provide at least 5 heuristic hints covering different strategic dimensions.
+- Assess how dependent the deck is on the commander being in play.
+- Evaluate opening hand quality and identify cards that cause bad mulligans.
+- Rank your suggested swaps by priority so the user knows what to change first.
+- Categorize the removal package by permanent type and flag coverage gaps.
+- Evaluate the ramp package for fragility (creature/artifact-heavy vs land-based).
+- Distinguish one-time draw from repeatable draw engines.
+- Identify the top 3 win conditions and rate each for independence.
+- Flag internal anti-synergies or card conflicts.
+- Assess pod threat perception: does this deck draw too much hate too early?

+## 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.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:

+    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.

+## Phased Timeline

+| **1** | Forge subprocess bridge + DTO definitions | 2–3 days |
+| **2** | AI Orchestrator + brain selector + prompt builder + personality system | 3–4 days |
+| **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. |

+═════════════════════════════════════════════════
+Reusable eval harness that:
+  1. Starts the policy inference server pointing at a given checkpoint
+  2. Launches Forge games via MultiThreadBatchRunner with the policy
+     server wired in as the AI decision-maker
+  3. Collects per-game metrics and writes a JSON results file
+
+Metrics collected per game:
+  - won          : bool
+  - turns        : int
+  - life_final   : int  (winning seat final life)
+  - life_delta   : int  (winner life - loser life at game end)
+  - cmd_damage   : int  (commander damage dealt by policy seat)
+  - illegal_acts : int  (actions rejected by Forge — should be 0)
+  - entropy_mean : float (mean policy entropy across decision steps)
+  - inference_ms : float (mean per-step inference latency)

+Commander AI Lab — Forge Evaluator (Issue #153)
+═════════════════════════════════════════════════
+Reusable eval harness that:
+  1. Starts the policy inference server pointing at a given checkpoint
+  2. Launches Forge games via MultiThreadBatchRunner with the policy
+     server wired in as the AI decision-maker
+  3. Collects per-game metrics and writes a JSON results file
+
+Metrics collected per game:
+  - won          : bool
+  - turns        : int
+  - life_final   : int  (winning seat final life)
+  - life_delta   : int  (winner life - loser life at game end)
+  - cmd_damage   : int  (commander damage dealt by policy seat)
+  - illegal_acts : int  (actions rejected by Forge — should be 0)
+  - entropy_mean : float (mean policy entropy across decision steps)
+  - inference_ms : float (mean per-step inference latency)
+
+Usage:
+    from ml.eval.forge_evaluator import ForgeEvaluator, EvalConfig
+    cfg = EvalConfig(
+        checkpoint_path="ml/models/checkpoints/forge-trained/final.pt",
