docs: rewrite README to reflect full current feature set

fix(coach): switch all Anthropic calls to streaming to prevent 10-min timeout error (closes #109 )
- anthropic_client.py: all 4 methods (chat_structured, chat_plain, achat_structured, achat_plain) now use .messages.stream() context manager - coach_service.py: inline aclient.messages.create() replaced with async streaming via aclient.messages.stream() - _parse_response() updated to accept pre-extracted text string (since stream gives us text directly) - check_status() left as non-streaming (max_tokens=10, safe from the 10min rule)

 ## Quick Start (Windows)

-### Prerequisites
- **Java 17+** (`java -version`)
- **Python 3.10+** (`python --version`)
- **Maven 3.8+** (`mvn --version`)
- **Forge repo** cloned and built at `D:\ForgeCommander\forge-repo`
+**Prerequisites:** Java 17+, Python 3.10+, Maven 3.8+, [Forge](https://github.com/Card-Forge/forge) built at `D:\ForgeCommander\forge-repo`

-### 1. Build Forge (one-time)
 ```powershell
+# 1. Build Forge (one-time)
 cd D:\ForgeCommander\forge-repo
 mvn package -pl forge-gui-desktop "-DskipTests" "-Drevision=2.0.12-SNAPSHOT" -am
-```

-### 2. Build Commander AI Lab
-```powershell
+# 2. Build Commander AI Lab
 cd D:\ForgeCommander\commander-ai-lab
 mvn package "-DskipTests"
-```
-This produces `target/commander-ai-lab-1.0.0-SNAPSHOT.jar` (shaded fat JAR).

-### 3. Install Python dependencies
-```powershell
-pip install fastapi uvicorn
-```
+# 3. Install Python deps
+pip install -e .

-### 4. Launch the Web UI
-**Option A — One-click launcher:**
-```powershell
+# 4. Launch
 .\start-lab.bat
+# → open http://localhost:8080
 ```
-Edit the paths at the top of `start-lab.bat` if needed.

-**Option B — Manual launch:**
+## Overnight AFK Runner
+
+Runs batch sims unattended, then updates card weights and trains the neural net:
+
 ```powershell
-python lab_api.py `
-  --forge-jar "D:\ForgeCommander\forge-repo\forge-gui-desktop\target\forge-gui-desktop-2.0.12-SNAPSHOT-jar-with-dependencies.jar" `
-  --forge-dir "D:\ForgeCommander\forge-repo\forge-gui" `
-  --port 8080
+python overnight-run.py                          # default: 11.5h DeepSeek sims
+python overnight-run.py --batches 20 --games 50  # fixed batch count
+python overnight-run.py --no-update-weights      # skip weight update
+python overnight-run.py --no-train               # skip neural net training
 ```

-Open `http://localhost:8080` — select 3 decks, set game count, click **Run AI Sims**.
+**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
+
+## Sim → Deck Builder Feedback Loop
+
+Simulation outcomes automatically improve deck recommendations:
+
+```
+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
+```
+
+When active, `BuildResult.sources_consulted` includes `"sim_weights"`. No-op until real sim data exists.
+
+## Deck Builder Pipeline
+
+The `POST /api/deck-builder/build` endpoint runs 7 steps:
+
+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 ← **sim insights injected here**
+5. Filter by color identity, collection, ban list
+6. Ollama enforces ratios (trim/expand to 99) ← **sim insights injected here**
+7. Assemble final deck
+
+## ML Pipeline

-### 5. CLI-only usage (no web server)
 ```powershell
-cd D:\ForgeCommander\forge-repo\forge-gui
+# Update sim card weights from decision logs (runs automatically in overnight-run.py)
+python -m ml.scripts.update_weights --min-games 10 --lr 0.05 --dry-run

-java -jar "D:\ForgeCommander\commander-ai-lab\target\commander-ai-lab-1.0.0-SNAPSHOT.jar" `
-  --forge-jar "..\forge-gui-desktop\target\forge-gui-desktop-2.0.12-SNAPSHOT-jar-with-dependencies.jar" `
-  --forge-dir "." `
-  --deck1 "Edgar Markov" `
-  --deck2 "Grimgrin" `
-  --deck3 "Xyris" `
-  --games 100 `
-  --threads 4 `
-  --output results/batch-100.json
+# Reset weights to defaults
+python -m ml.scripts.update_weights --reset
+
+# Generate synthetic training data
+python ml/scripts/generate_synthetic_data.py
 ```

-## Scaling Tests
+Learned weights are clamped to `[-20.0, 20.0]` and stored in `src/commander_ai_lab/sim/learned_weights.json`.

-### Single-threaded baseline (10 games)
-```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 1 --output results/baseline-10.json
+## Python Simulator API
+
+```python
+from commander_ai_lab.lab.experiments import build_deck, run_simulation
+
+deck = build_deck(["Sol Ring", "Cultivate", "Lightning Bolt"] + ["Forest"] * 36)
+stats = run_simulation(deck, num_games=100, name_a="My Deck")
+print(f"Win rate: {stats['win_rate']:.1%}, Avg turns: {stats['avg_turns']:.1f}")
 ```

-### Multi-threaded (10 games, 2 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 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.
+The Monte Carlo engine models: combat keywords (flying, trample, deathtouch, lifelink, menace, reach, haste), summoning sickness, tapped/untap state, commander zone, multiplayer attack targeting, and board wipes. It does **not** model the stack, instants, or continuous type-changing effects.

-
-### Install as editable package
-
-```powershell
-cd D:\ForgeCommander\commander-ai-lab
-pip install -e .
-```
-
-This installs `commander_ai_lab` as an importable package and registers the `commander-sim` CLI command.
-
-### Quick smoke test
-
-```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"] + ["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"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.

-## Output Format
-
-Each batch run produces JSON conforming to `docs/batch-result-schema.json`:
-```json
-{
-  "metadata": {
-    "schemaVersion": "1.0.0",
-    "batchId": "uuid",
-    "timestamp": "2026-03-06T...",
-    "totalGames": 100,
-    "completedGames": 100,
-    "format": "commander",
-    "podSize": 3,
-    "engineVersion": "forge-2.0.12-SNAPSHOT",
-    "masterSeed": 42,
-    "threads": 4,
-    "elapsedMs": 260000
-  },
-  "decks": [...],
-  "games": [...],
-  "summary": {
-    "perDeck": [
-      { "deckName": "Edgar Markov", "winRate": 0.60, "wins": 60, ... }
-    ],
-    "avgGameTurns": 12.3,
-    "simsPerSecond": 0.38
-  }
-}
-```
-
-## Frontend Development
-
-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
- Each game spawns a new JVM process (~2-3s overhead per game)
- Max throughput ~0.04 sims/sec single-threaded (Forge sim is CPU-heavy)
- Multithreading spawns parallel subprocesses — throughput scales linearly with threads up to CPU core count
+
+- **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

+# Closed-Loop Iterative Distillation — Implementation Roadmap
+
+> **Goal:** Create a feedback loop where the PPO self-play agent exports its game decisions
+> as JSONL files, which the supervised training pipeline incorporates alongside Forge
+> heuristic data. The supervised baseline gradually improves as the RL agent discovers
+> better play patterns — the RL agent teaches the supervised model.
+
+---
+
+## Phase 1 — PPO Decision Exporter
+
+**Goal:** PPO self-play writes decisions in the same JSONL format as Forge batch sims.
+
+- [ ] Add a `DecisionExporter` class in `ml/training/self_play.py` that captures each
+      (state, action, reward, game_context) during PPO rollouts
+- [ ] Write to `data/results/ml-decisions-ppo-{batch_id}.jsonl` using the exact same
+      schema as the Forge `DecisionSnapshot` files
+- [ ] Include metadata fields to distinguish PPO-generated data:
+  - `"source": "ppo"`
+  - `"model_version"`
+  - `"reward"`
+  - `"episode_return"`
+- [ ] Only export decisions from **winning** games initially (higher signal-to-noise)
+
+**Files touched:** `ml/training/self_play.py`, new `ml/training/decision_exporter.py`
+
+---
+
+## Phase 2 — Dataset Builder Source Awareness
+
+**Goal:** `dataset_builder.py` can ingest both Forge and PPO decision files with
+configurable mixing.
+
+- [ ] Update `build_dataset()` to scan for both `ml-decisions-sim-*.jsonl` (Forge) and
+      `ml-decisions-ppo-*.jsonl` (PPO) files
+- [ ] Add a `source_weights` config param — e.g., `{"forge": 1.0, "ppo": 0.5}` — to
+      control sampling ratios so PPO data doesn't overwhelm the Forge baseline early on
+- [ ] Add a `min_reward_threshold` filter for PPO data — only include decisions from
+      games above a certain reward score
+- [ ] Tag each sample with its source for downstream analysis
+
+**Files touched:** `ml/data/dataset_builder.py`, `ml/config/scope.py`
+
+---
+
+## Phase 3 — Quality Gate & Validation
+
+**Goal:** Prevent bad PPO data from degrading the supervised model.
+
+- [ ] Add a validation split in `dataset_builder.py` (hold out 10-15% of Forge data as
+      a fixed eval set)
+- [ ] After each supervised training run, evaluate on the held-out Forge set — if
+      accuracy drops below a threshold compared to the previous model, reject the PPO
+      data batch
+- [ ] Track win rate of the PPO agent — only export decisions once the PPO model exceeds
+      a configurable win rate (e.g., >30% in 4-player pods, above the 25% random baseline)
+- [ ] Log data quality metrics: action distribution entropy, reward distribution of
+      exported games
+
+**Files touched:** `ml/training/trainer.py`, `ml/eval/`, new `ml/data/quality_gate.py`
+
+---
+
+## Phase 4 — Distillation Loop Orchestrator
+
+**Goal:** Automate the full cycle: supervised train -> PPO self-play -> export -> retrain.
+
+- [ ] New `ml/training/distillation_loop.py` that orchestrates:
+  1. Supervised train on current dataset (Forge + any existing PPO data)
+  2. Run N episodes of PPO self-play using the new supervised model as starting policy
+  3. Export winning PPO decisions to JSONL
+  4. Quality gate check
+  5. If passed, merge into dataset and go to step 1
+  6. If failed, discard PPO batch, adjust hyperparameters, retry
+- [ ] Add `max_iterations` and `convergence_check` (stop if win rate plateaus across
+      iterations)
+- [ ] Each iteration is a "generation" — tag data and models with generation number
+
+**Files touched:** new `ml/training/distillation_loop.py`, `ml/config/scope.py`
+
+---
+
+## Phase 5 — UI Integration & Monitoring
+
+**Goal:** Expose the distillation loop in the Commander AI Lab web UI.
+
+- [ ] Add a "Distillation" tab or section in `ui/ai-lab.js` showing:
+  - Current generation number
+  - Per-generation win rate trend chart
+  - Data composition pie chart (% Forge vs % PPO per generation)
+  - Start / stop / pause controls for the loop
+- [ ] API endpoints in `routes/ml.py`:
+  - `POST /api/ml/distill/start`
+  - `GET /api/ml/distill/status`
+  - `POST /api/ml/distill/stop`
+- [ ] History of each generation's metrics stored as JSON for the trends view
+
+**Files touched:** `routes/ml.py`, `ui/ai-lab.js`, `ui/ai-lab.css`
+
+---
+
+## Phase 6 — Advanced: ELO Tracking & Model Tournament
+
+**Goal:** Quantify improvement across generations.
+
+- [ ] Pit each generation's model against previous generations and the Forge heuristic
+      in batch sims
+- [ ] Compute ELO ratings per generation
+- [ ] Store in `data/elo_history.json` and visualize in the UI as a line chart
+- [ ] Use ELO delta as a convergence signal — stop the loop when ELO gain per generation
+      drops below a threshold
+
+**Files touched:** new `ml/eval/elo_tracker.py`, `routes/ml.py`, `ui/ai-lab.js`
+
+---
+
+## Priority
+
+| Phase | Priority | Description |
+|-------|----------|-------------|
+| 1     | **Critical** | PPO decision export — foundation for everything |
+| 2     | **Critical** | Dataset builder ingests both sources |

+| 5     | Medium   | UI visibility and controls |
+| 6     | Low      | ELO tracking and tournament system |
+
+> **Phases 1-3** are the core — get those working and you have a functional closed loop.
+> **Phase 4** automates it. **Phases 5-6** are polish and observability.

+- [x] `_macro_action_to_forge_type()` mapping (MacroAction enum → Forge action type strings)
+- [x] Export stats tracking (`stats` property)
+
+---
+
+## Remaining — Integrate into `ml/training/self_play.py`
+
+### Import
+
+- [ ] Add import: `from ml.training.decision_exporter import DecisionExporter`
+
+### Modify `run_self_play_episode()` 
+
+- [ ] Add `exporter: DecisionExporter = None` parameter to function signature
+- [ ] After each `trajectory.append(...)` block (3 locations), add:
+  ```python
+  if exporter is not None:
+      exporter.record_step(
+          game_state_snapshot=prev_snapshot,
+          action_idx=action_idx,
+          reward=reward,
+      )
+  ```
+
+### Modify `collect_rollouts()`
+
+- [ ] Add `exporter: DecisionExporter = None` parameter to function signature
+- [ ] Before each episode, call:
+  ```python
+  if exporter is not None:
+      exporter.begin_episode(agent_seat=agent_seat, playstyle=playstyle)
+  ```
+- [ ] Pass `exporter=exporter` to `run_self_play_episode()`
+- [ ] After outcome tracking, call:
+  ```python
+  if exporter is not None:
+      won = trajectory and trajectory[-1]["done"] and trajectory[-1]["reward"] > 0.5
+      ep_return = sum(s["reward"] for s in trajectory)
+      exporter.end_episode(won=won, episode_return=ep_return)
+  ```
+
+### Commit
+
+- [ ] `git add ml/training/self_play.py`
+- [ ] `git commit -m "feat(ml): integrate DecisionExporter into self-play rollouts (#65)"`
+- [ ] `git push origin main`
+
+---
+
+## Integration Pattern
+
+```
+collect_rollouts(exporter=exporter)
+  └─ for each episode:
+       ├─ exporter.begin_episode(seat, playstyle)
+       ├─ run_self_play_episode(..., exporter=exporter)
+       │    └─ for each step:
+       │         ├─ trajectory.append(step_data)
+       │         └─ exporter.record_step(snapshot, action, reward)
+       └─ exporter.end_episode(won, episode_return)
+  # Caller does: exporter.flush()
+```
+
+---
+
+## Terminal Commands
+
+```bash
+cd commander-ai-lab
+git pull origin main
+# Make edits to ml/training/self_play.py per checklist above
+git add ml/training/self_play.py
+git commit -m "feat(ml): integrate DecisionExporter into self-play rollouts (#65)"
+git push origin main

-# React + TypeScript + Vite
-
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
-
-Currently, two official plugins are available:
-
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
-
-## React Compiler
-
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
-
-## Expanding the ESLint configuration
-
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
-
-```js
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```
-
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
-
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
-
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
