Add Phase 8 — Multiplayer (Human vs Human + AI)

- run_n() accepts 2-4 decks; run() wraps for backward compat
- _select_attack_target() heuristic for multiplayer combat targeting
- N-player elimination order tracking with finish positions
- Removal scans all opponents for scariest creature
- ML snapshot captures all N players
- Log entries use per-seat boards dict with legacy boardA/boardB for 2-player

-# FarmHouse changes
-
-This branch (`farmhouse`) is `KoalaTrapLord/commander-ai-lab` at commit `54cc5e9` plus the changes below. They were made to run the app
-**Python-only** (no Forge/Java, no PyTorch) in a Kubernetes namespace, with a local LLM behind an OpenAI-compatible gateway instead of
-Anthropic/DeepSeek, and they were each found by actually running the app, not by reading it. Written 2026-10-26.
-
-Every change started life as an anchored text patch (`patch_app.py` in the farmhouse-os repo, which still builds the deployed image from
-the upstream commit); here they are ordinary source edits. Lines carry a `# FARMHOUSE_...` marker where the patch left one.
-
-## What was wrong, and what changed
-
-### The simulator played nothing (the big one)
-| Problem | Change |
-|---|---|
-| Every card reached the simulator with **no type line and no rules text**. The loaders join the user's *collection* and a *card_records* table (both empty on a fresh install) and the Forge card cache that was meant to fill the gap is not installed. A land was indistinguishable from a creature: an 8-game batch cast 0 spells, dealt 0 damage and lost every game. | `services/farmhouse_sim.py` `fill_card_data` fills type, text, mana cost, cmc, P/T, keywords and colour identity from the 113k-card Scryfall bulk database. Wired into `services/forge_runner.py` (batch) and `routes/deepseek.py` (`_fetch_deck_card_data`, which the Monte Carlo and single-deck routes use). |
-| The batch loader **did not repeat cards by quantity**: a 100-card deck loaded as 66-84 cards with *one* Island. | `expand_quantities` (same module). |
-| The LLM engine asked the model **once per turn** and applied the answer as one action. | `src/commander_ai_lab/sim/farmhouse_turns.py`: up to `BRAIN_STEPS` (default 4) questions per turn (land, spell, spell, attack), re-reading the board after each; stops on attack/hold/no change. `BRAIN_STEPS=1` restores the original. |
-| A model that "thinks" spent ~46 s on a one-line move. | `deepseek_brain.py` sends `reasoning_effort` from `LLM_REASONING` (46 s -> 1.8 s per move). |
-| The engine dropdown defaulted to **Forge**, which cannot run without Java. | `ui/ai-lab.js`: only "LLM opponents" is offered. |
-
-After the fixes: a 40-game Monte Carlo takes 0.4 s with real numbers (10 spells and 12.7 damage per game); two LLM-piloted games took
-212 s with 49 model calls and no fallbacks.
-
-### Deck import
-| Problem | Change |
-|---|---|
-| **Moxfield links were accepted nowhere**, and the Deck Builder import took only pasted text. | `services/farmhouse_deck_links.py`: Moxfield (public decks, `api2.moxfield.com`) and Archidekt links in the simulator URL import and in both Deck Builder imports (a lone link in the paste box). A private deck says to use Moxfield's Export > Copy as text. |
-| The Deck Builder import looked **every card up on scryfall.com**; after a few dozen it was rate-limited (HTTP 429) and the app reported the rest as "not found" (250-card deck: 55 matched; even plain `Sol Ring` failed). | `local_card()`: names resolve from the local bulk database first; the website is only the fallback. |
-
-### Deck generation
-- `deck_builder/pipeline/farmhouse_fit.py`: the model's list is **filtered to the commander's colour identity** (from the bulk DB), de-duplicated,
-  fitted to per-category targets and trimmed to 99 + commander. Before this the model returned off-colour cards and 359-card lists.
-- Scryfall bulk format changed (`jsonl_download_uri`, gzip JSONL; no `download_uri`).
-- Scryfall answers **HTTP 400 to the default `python-requests` User-Agent** (every lookup became "Commander not found"): a named UA is sent everywhere.
-- Scryfall 429s: requests back off on `Retry-After` and the pace is 0.25 s.
-- `LLM_REASONING` / `LLM_MAX_TOKENS` are sent by the deck builder and coach.
-
-### Coach / startup
-- The coach was only initialised in `main()`, not when the app starts under uvicorn; `check_connection_sync()` was called but never defined;
-  the coach used the first model the gateway listed rather than the configured one. All fixed.
-- Status label says "Language model" instead of the hardcoded "Claude Opus".
-- `RAG_AUTOBUILD` (default off in our deployment) controls whether the card-search index is built at startup (113k embeddings; about an hour).
-
-### Decision model (Laya / Kev), wired and off
-`src/commander_ai_lab/sim/farmhouse_decide.py` asks a `/v1/systemone` server which of the nine actions to take, in one forward pass.
-`DECISION_MODE=shadow` records whether it agrees with the LLM (the game still uses the LLM); `assist` uses it when `DECISION_MIN_CONF`
-sure; `off` (default) does nothing. `scripts/farmhouse_decision_eval.py` replays recorded decisions through it.
-
-**Measured 2026-10-26 on 149 recorded LLM decisions: zero-shot, both Laya checkpoints agreed with the LLM less often than always
-guessing the commonest action** (English 16.1%, typed-decisions 18.6%, baseline 27.5%), at 2-4 s per answer on a 4-thread CPU. It is only
-worth using after fine-tuning on this game's decisions; the write-up is `LAYA-EVALUATION.md` in the farmhouse-os repo's commander-lab folder.
-
-### Laya connections (all off by default)
-Forge's concrete priority path, extra typed questions in the same call, a capture log, a fine-tuning dataset exporter, and card-role classification:
-`src/commander_ai_lab/sim/farmhouse_laya.py`, `scripts/farmhouse_laya_dataset.py`, `scripts/farmhouse_laya_roles_eval.py`, tests `tests/farmhouse/test_farmhouse_laya*.py`.
-How it fits the strategic-intelligence work, what is measured and how to fine-tune: [docs/LAYA-CONNECTIONS.md](docs/LAYA-CONNECTIONS.md). Reference copies of the Laya
-image, manifests and CI are in `farmhouse/laya/`.
-
-### Forge, and rules-accurate simulation with phase-rs
-- **Forge is installed** in the cluster image (it was left out by mistake): `farmhouse/forge/README.md`. Batches are clamped to one game at a time (`FORGE_MAX_THREADS`).
-- **Rules-accurate simulation** through the phase-rs engine (Rust, headless): `routes/farmhouse_phase.py`, `ui/phase-sim.html` (linked from the home page) and the service in
-  `farmhouse/phase/`. Four saved decks play real Commander games; the page shows wins by seat with a 95% interval and warns about cards the engine did not recognise.
-  Seats can be put on a **model** (twin-turbo through Olla, or Laya): the model chooses among the engine's own legal options only, anything wrong or slow is played by phase's AI,
-  and a call cap bounds the cost (`farmhouse/phase/README.md`). Assessment and plan: `docs/PHASE-AND-PLAYTESTER.md`.
-
-## Settings (environment variables)
-| Variable | Meaning |
-|---|---|
-| `LLM_URL`, `LLM_MODEL` | OpenAI-compatible endpoint (`.../v1`) and model for the coach and deck builder |
-| `LLM_REASONING` (`none`), `LLM_MAX_TOKENS`, `LLM_TIMEOUT` | keep requests lean: reasoning off, cap on answer length |
-| `COACH_PROVIDER`, `DECK_GEN_PROVIDER` = `local`, `DECK_GEN_MODEL` | use the local model, not Anthropic |
-| `OLLAMA_BASE_URL`, `RAG_EMBEDDING_MODEL`, `RAG_AUTOBUILD` | card-search embeddings (one host only: vectors differ between hosts) |
-| `BRAIN_API_BASE` (**no** `/v1`; the client appends it), `BRAIN_MODEL`, `BRAIN_MAX_TOKENS`, `BRAIN_STEPS` | the simulator's LLM opponents |
-| `DECISION_URL`, `DECISION_MODEL`, `DECISION_MODE` (`off`/`shadow`/`assist`), `DECISION_MIN_CONF`, `DECISION_TIMEOUT` | the decision model above |
-| `ollama` Python package | required by the card-search index build (ChromaDB's Ollama embedder imports it) |
-
-## Tests
-`tests/farmhouse/` (standard library only, no network): `python -I -X utf8 tests/farmhouse/test_farmhouse_deck_links.py`, `..._sim.py`, `..._fit.py`.
-Run them with `-I` and from outside the package folders; do not put `services/` on `sys.path` (`services/logging.py` shadows the standard library).
-
-## Things still worth doing
-- **Make the LLM-opponent turns faster** (a piloted move averages ~7.5 s: about 2.2k tokens in, ~30 out, so reading the prompt dominates).
-  These are ideas, not measured; none is implemented:
-  - *Shared prefix:* about 1.2k tokens of every prompt (the system prompt) are identical each time; a llama.cpp server can reuse them
-    if the calls share the prefix, so only the board state is read each move.
-  - *Smaller prompt:* send a compact board state instead of the indented JSON the engine builds now (`json.dumps(snapshot, indent=2)`
-    in `deepseek_brain.py`).
-  - *Parallel games:* run several games at once, which would also fill the GPU while one game waits on a move. Caveat: for long prompts
-    two requests at once gave no extra throughput on a V100 (reading the prompt is compute-bound), so measure before relying on it.
-- Opponents are the engine's heuristics; only the piloted seat uses the model.
-- Build the card-search index and measure it.
-- The upstream `LICENSE` is missing (`pyproject.toml` says MIT). Ask the author to add one before publishing a derivative widely.
-- Forge-based features (the Java simulator, training) remain unavailable by design.

 # Commander AI Lab
 
-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.
-
----
-
-## 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

-## 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.

+```
 
-# 4. Pull an Ollama model for the deck builder
-ollama pull qwen2.5:7b
-
-# 5. Launch
+### 4. Launch the Web UI
+**Option A — One-click launcher:**
+```powershell
 .\start-lab.bat
-# → Web UI:        http://localhost:8080
-# → LAN Client:    http://localhost:8080/lan/
 ```
+Edit the paths at the top of `start-lab.bat` if needed.
 
-Or use the automated installer:
-
+**Option B — Manual launch:**
 ```powershell
-.\install-commander-ai-lab.ps1
+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
 ```
 
----
-
-## Overnight AFK Runner
-
-Run batch simulations unattended, then automatically update card weights and train the neural net:
+Open `http://localhost:8080` — select 3 decks, set game count, click **Run AI Sims**.
 
+### 5. CLI-only usage (no web server)
 ```powershell
-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
+cd D:\ForgeCommander\forge-repo\forge-gui
+
+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
 ```
 
-**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
+## Scaling Tests

-update_weights.py → learned_weights.json
-       ↓
-sim_insights.py → natural-language insight block
-       ↓
-Ollama prompts (suggest_cards + enforce_deck_ratios)

-## Python Simulator API
+### 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
 
-deck = build_deck(["Sol Ring", "Cultivate", "Lightning Bolt"] + ["Forest"] * 36)
+# 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%}, Avg turns: {stats['avg_turns']:.1f}")
+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.

 ## Known Limitations
-
-- **Monte Carlo engine** — no stack, no instants, no continuous type-changing effects (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 in quiet mode (only reports losers)
-- **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)

+- 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

 - Base suggestions on the simulation data provided, not general "goodstuff" advice.
 - Consider mana curve, role balance (ramp, draw, removal, threats), and synergy.
 - When suggesting replacements, prefer cards that fill the same functional role.
-- IMPORTANT: Suggest 5-8 DIFFERENT cards to cut and 5-8 DIFFERENT cards to add.
+- IMPORTANT: Suggest 3-5 DIFFERENT cards to cut and 3-5 DIFFERENT cards to add.
 - Each suggested add MUST be a different card — never suggest the same card twice.
 - Vary your suggestions across different functional roles (ramp, draw, removal, threats, utility).
 - If the deck is missing a functional role (e.g., no card draw, no removal), prioritize adding cards for that role.
 - If candidate replacements are provided from embeddings search, prefer those over generic suggestions.
-- For each suggested cut, provide a DETAILED reason citing specific stats (impact score, cast rate, dead card rate, clunkiness, synergy score).
-- For each suggested add, explain the SPECIFIC synergy with existing cards in the deck.
-- When reasoning about cuts, also consider keptInOpeningHandRate (low = bad in opening hands) and avgTurnCast (high = too slow for the curve).
-- When evaluating synergy, use the synergyScore: cards below 0.1 have weak co-occurrence with the rest of the deck.
-- 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 [OPENING HAND TRAP] have keptInOpeningHandRate below the deck average — treat as mulligan liabilities.
-- 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?
-- Evaluate when the deck comes online (tempo profile) and whether that's viable.
-- Reason about matchups vs fast combo, stax/prison, and control archetypes.

-# 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 |
-| 3     | **Critical** | Quality gate prevents model regression |
-| 4     | High     | Automation of the full loop |
-| 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.

-# Laya connections
-
-Laya (and Kev: same `POST /v1/systemone` API) is a **decision model**: typed multiple-choice, yes/no and score questions about a text, answered in
-one forward pass, no generated text. This page is where it plugs into the strategic-intelligence work in this repository
-([INTELLIGENCE-HANDOFF.md](INTELLIGENCE-HANDOFF.md)), what is measured, and how to make it worth using. Written 2026-10-26.
-
-**Short version.** Every connection below is built, tested offline and **off by default**. Zero-shot, Laya is a poor action chooser
-(below the always-guess baseline) but a reasonable card classifier (48% against 17% by chance); it is too slow on a CPU for Forge's
-priority path (8 s against a 1.5 s budget). The way forward is fine-tuning on the decisions these connections record.
-
-## What connects where
-
-| Connection | Code | Mode | Notes |
-|---|---|---|---|
-| Farmhouse macro choice: Laya picks among CSIE's candidate macros, reading the CSIE ranking and ITI objective in its text | `farmhouse_decide.py` (called from `deepseek_brain.py`) | `DECISION_MODE=shadow` records agreement with the LLM; `assist` uses a pick it is `DECISION_MIN_CONF` sure of | existing; only offered candidates are accepted |
-| **Forge concrete priority choice**: Laya picks among the same concrete candidate IDs Forge sent to `/api/policy/decide/concrete` | `farmhouse_laya.advise_concrete` / `attach_concrete`, called from `routes/policy.py` | `shadow`: adds `laya` to the response, selection unchanged. `assist`: may replace `selected_id`, never one Forge tagged `stops_immediate_win` / `wins_now`; the original is kept as `csie_selected_id` | candidate described by kind, card, cost, target, tags (never by its opaque id); Forge still executes only an ID it sent |
-| **Extra questions in the same call**: "how dangerous are the opponents' boards?" (none/low/moderate/high/lethal) and "is there a threat that must be answered?" | `farmhouse_laya._extra_questions` | whenever Laya is asked | one forward pass answers all questions, so they cost almost nothing; recorded as weak signals for the learned-threat work, **not used to decide** |
-| **Capture**: every call is appended to `data/decisions/laya-shadow-<date>.jsonl` (`laya-shadow-v1`) | `farmhouse_laya.capture` | shadow / assist | the text Laya read, the offered options, its answer and extras, and the other deciders' picks (`labels`: `llm`, `csie`, `selected`) |
-| **Fine-tuning data**: capture log -> `train.jsonl` / `valid.jsonl` / `manifest.json`, split by game, with the baselines to beat | `scripts/farmhouse_laya_dataset.py` | offline | the manifest reports commonest-action, CSIE-vs-teacher and Laya-zero-shot agreement on the validation side |
-| **Card role evidence**: removal, board wipe, ramp, card draw, counterspell, protection, tutor, creature, other, from Oracle text | `farmhouse_laya.classify_roles` (batched, cached, with `source: laya:<model>` provenance); `scripts/farmhouse_laya_roles_eval.py` measures it | on demand | evidence for ITI / Tagger-style use, never a rules fact |
-
-Not built (still the open items in the handoff, none of which Laya can substitute for): compiling and running the Forge controller, the bounded
-combo executor, the multi-turn planner, the calibrated learned-threat model. Laya's "threat" and "must answer" extras are only raw material for that last one.
-
-## Where the hooks are
-- `src/commander_ai_lab/sim/farmhouse_decide.py` (committed): the macro-choice client gained the extra questions, the state text/options in its
-  answer, and `record()` writes the capture line.
-- `routes/policy.py` (**working tree only, uncommitted**: the route itself is part of the pending strategic-evaluator work, so the hook was
-  left for that commit). It is one block in `decide_concrete`, after the result is computed:
-  `if _L.mode() != "off": advice = await run_in_threadpool(_L.advise_concrete, ...); result = _L.attach_concrete(...)`, guarded by `except ImportError`.
-- Everything else is new files: `farmhouse_laya.py`, the two scripts, `tests/farmhouse/test_farmhouse_laya*.py`, `farmhouse/laya/`.
-
-## Settings
-`DECISION_URL` (e.g. `http://laya.commander-lab.svc.cluster.local:8080`), `DECISION_MODE` (`off` default / `shadow` / `assist`), `DECISION_MODEL`
-(a checkpoint such as `typed-decisions`), `DECISION_MIN_CONF` (0.7), `DECISION_TIMEOUT` (5 s), `DECISION_TIMEOUT_FORGE` (**1.5 s**: Forge waits on this),
-`DECISION_API_KEY`, `LAYA_CAPTURE_DIR` (`data/decisions`), `LAYA_CAPTURE=0` to stop writing capture lines. Three failures in a row pause asking for a minute.
-
-## Rules the code enforces
-1. Text is built from public facts and the acting player's own hand. An opponent's `hand` field is never read, even if a client sends one (tested).
-2. Laya's answer must be one of the options that were offered; anything else is discarded.
-3. In assist, a pick Forge marked `stops_immediate_win` / `wins_now` is never overridden, and the response says what CSIE chose.
-4. A missing, slow or broken server returns "no answer"; nothing raises and the game proceeds as without Laya.
-5. Scores and probabilities are relative signals; Laya's probabilities are not calibrated for this game.
-
-## What was measured (2026-10-26, `typed-decisions` checkpoint, 4-thread CPU)
-- **Macro action vs the LLM, 149 recorded decisions:** 16.1% (English) and 18.6% (typed-decisions); always guessing the commonest action 27.5%.
-- **Forge-shaped priority choice, 3 scenarios, with CSIE's ranking in the text:** agreed with CSIE all three times (expected: the ranking is in the
-  text it reads), 42-48% sure, **7.5-8.4 s per call** with the extra questions. That is five times Forge's 1.5 s budget: on this CPU the Forge path
-  would time out and fall back; it needs a GPU (33 ms quoted) or a smaller text.
-- **Extras:** "threat" said *high* for a lethal stack, a calm board and a behind board alike (useless zero-shot); "must answer" gave 0.48 for the
-  lethal stack against 0.25 and 0.29 for the others (right direction, weak).
-- **Card roles from Oracle text, 150 unambiguous cards:** 48.0% (16.7% by chance among the six roles present); counterspell 76%, board wipe 64%,
-  removal 40%, tutor 40%, ramp 36%, card draw 32%; when 70% sure, 69% right but only 11% of cards reach that. **3.2 s per card** in batches on the CPU:
-  fine for the cards in a hand (cached), not for tagging 30,000 cards (about a day).
-
-## How to make it worth using
-1. Run games with `DECISION_URL` set and `DECISION_MODE=shadow` (Farmhouse LLM games, and Forge games through `/api/policy/decide/concrete`).
-2. `python scripts/farmhouse_laya_dataset.py --teacher llm` (or `csie`, or `selected`). Read `manifest.json`: the **validation baselines** are the bar.
-   A student of CSIE can at best equal CSIE, which is free; a student of the LLM is the useful one. Several thousand rows are needed.
-3. Fine-tune with Laya's own notebook/script (github.com/NandhaKishorM/laya, `notebooks/`; 2xT4 about 4-5 hours, or Apple silicon). Its worked example
-   (browser agent choosing among ~45 concrete candidates) went from 0.10 zero-shot to 0.66, so a concrete-candidate head is the shape that works.
-   Adapt the row field names if its loader differs.
-4. Serve the result (`LAYA_EXTRA_MODELS` / `DECISION_MODEL`), rerun `scripts/farmhouse_decision_eval.py` and the dataset manifest, and only then
-   try `assist`. A GPU host makes the Forge path possible.
-5. Keep game result and decision quality separate (handoff boundary 6 / learned-threat contract): a captured label is a teacher's choice, not proof it was right.
-
-Deployment reference copies are in `farmhouse/laya/` (image, manifests, CI); the source of truth is the farmhouse-os GitOps repo.

-# phase-rs and commander-playtester: assessment and plan
-
-Researched 2026-10-26 from the public repositories and data files only. **Nothing from either project has been run, vendored or deployed.**
-Facts marked (verified) were read from the source; (unverified) are inferences to check before building on them.
-
-## phase-rs/phase: a rules engine
-
-A Rust rules engine (turns, priority, the stack, combat, layers, triggers, replacement effects) that compiles to native and WebAssembly, with a game
-client, a WebSocket server and its own AI. Dual licensed Apache-2.0 / MIT (`LICENSE-APACHE`, `LICENSE-MIT`; GitHub's licence field shows "none" only
-because there are two files). Card data from MTGJSON (MIT); card images come from Scryfall at runtime; the repo says it bundles no card art or
-Comprehensive Rules text and has a DMCA/fan-content policy. One maintainer, young (weeks to months), fast-moving (latest engine tag v0.100.0).
-
-Why it matters here: our Python simulator has no rules stack (the handoff says so: `stack_supported: false`) and Forge needs a JDK and Maven that
-are not in the image. Phase is a rules-accurate engine that can run headless.
-
-### Coverage of the decks in this app (verified, from phase's published `coverage-data.json`)
-Phase reports 88.9% of 36,037 cards implemented overall and 92.5% for Commander. For the five saved decks, distinct cards supported:
-Empress V8 72/77, Landfall 65/66, God and Anime 69/71, Im not dead yet 82/84, Pew Pew 88/93: **376 of 391 (96.2%)**. The 15 unsupported cards have
-one or two parsing gaps each (e.g. Gale Waterdeep Prodigy, Hall of Echoes, Precursor Golem, Invigorate, Mavinda, Drana and Linvala, Tibalt's Trickery).
-"Supported" means every ability parsed; it is not a guarantee that each card plays correctly. How the engine treats an unsupported card in a game
-(blank, no-op, refused) is **unverified**; test it before trusting a result that involves one.
-
-### The parts that fit
-| Part | What it gives us | Notes |
-|---|---|---|
-| `ai-duel` (crate `phase-ai`) | headless AI-vs-AI games from the command line: seeded, deterministic "measurement mode", batches, JSON reports, a 4-player Commander suite, paired-seed comparison | decks are plain JSON `{"name", "main":[{"name","count"}]}` (verified). **No prebuilt binary is released**: it needs a Rust build (in CI or a container, not on the workstation). How a custom Commander deck and commander are supplied to `--commander-suite` is unverified (that suite reads a feed file) |
-| `phase-server` | a WebSocket game server (lobby, hidden information, spectators) | a prebuilt image is published (`ghcr.io/phase-rs/phase-server`, tags `latest`, `preview`, `sha-...`). A Python client could play seats and record every decision with real rules (protocol documentation not yet read) |
-| `phase-llm` | **model-driven AI seats**: the engine hands the model its legal option list, the model returns an index, the engine re-validates it, and any failure falls back to the heuristic AI | same principle as `farmhouse_laya.py`. Speaks OpenAI-style chat (so Olla / twin-turbo) **and the System One protocol Laya and Kev serve** (verified: `WireProtocol::SystemOneRelay`, question id `pick`, 2 to 255 options) |
-| `POST /jev/systemone` relay in `phase-server` | forwards the System One request to the URL in `TYPESAFE_API_URL` (verified, env var, `http` allowed for local setups) | point it at `http://laya...:8080/v1/systemone` to put Laya or Kev in a seat. The relay sends the key as `Authorization: Bearer` and does not follow redirects |
-
-The attraction for the Laya work: a captured decision from phase is an **engine-issued option list plus the pick**, in rules-accurate games. That
-is a better fine-tuning source than this repository's approximate simulator, and the exporter (`scripts/farmhouse_laya_dataset.py`) could take it with a small adapter.
-
-## RafaelAugustScherer/commander-playtester: a browser app on top of phase
-
-TypeScript/React single-page app, no backend. Runs phase's engine as WebAssembly in a Web Worker. Deck library with Moxfield / Archidekt / plain-text
-import, a goldfishing Monte Carlo (mulligan rate, screw and flood, land drops, ramp by turn 3, curve), real engine matches (watch, or pilot one seat),
-and 1-50 match head-to-head runs with a win rate and 95% confidence interval. Pins the phase engine in `engine-manifest.json` (v0.100.0; its README
-still says v0.57.0) and fetches the WASM and card data with SHA-256 checks. Zero stars, last pushed 2026-10-24.
-
-**It has no LICENSE file** (verified: the repository metadata shows none). Without a licence the code is all rights reserved: it can be read and used
-as a reference, but not copied into this repository or redistributed. Ask the author to add a licence (MIT would do) before reusing any of it. What is
-worth taking as ideas, not code: the goldfishing metrics, the head-to-head confidence-interval report, the name-only deck payload for the engine, and
-the engine-smoke gate that boots the real engine and plays a match to completion after every upgrade.
-
-## Recommended plan, smallest useful step first
-1. **Prove it on one deck.** Build `ai-duel` from the pinned phase tag in CI (Rust, container), convert one saved deck to the JSON format, run a seeded
-   batch against a baseline deck, and read the result. Answers: does it run a Commander game end to end, what does it do with an unsupported card, how
-   long is a game. This replaces the guesswork about the Python simulator's win rates.
-2. **A `phase-sim` service** in the commander-lab namespace (no egress, called only by the app) with an endpoint "run N rules-accurate games for deck X
-   against Y", returning win rate, confidence interval, wins by seat and the game log; the app's results panel reads it. The Python simulator stays for
-   instant, rough Monte Carlo.
-3. **Model seats.** Run `phase-server` with `TYPESAFE_API_URL` at Laya (or at a fine-tuned one later) and the OpenAI-compatible seat at Olla; compare
-   heuristic-only, LLM and Laya seats. Record every decision for the Laya dataset.
-4. **Only then** consider the playtester's UI ideas, after the author adds a licence or as a clean reimplementation.
-
-## What was built from this plan (2026-10-27)
-1. **The headless runner** (`ai-commander`, Commander four-player, batch mode) is built from the v0.118.0 tag with the card database that release was published with, in a
-   container (`farmhouse/phase/Dockerfile`). Not `ai-duel` for the decks: `ai-commander` takes a feed JSON of four decks, which is exactly what the app has.
-2. **The service and the app side**: `farmhouse/phase/phase_sim.py` (HTTP, jobs, parser, warnings) and `routes/farmhouse_phase.py` + `ui/phase-sim.html`. Games that stall, hit the
-   action cap or panic are reported and never counted.
-3. **Model seats**: not a setting. phase's model support lives only in its browser client (`engine-wasm` calls `phase-llm`; the HTTP is done by TypeScript), and
-   `phase-llm` depends on `phase-ai`, so the headless binary cannot use it. `farmhouse/phase/llm-seat/` is a new crate that includes the runner and installs a hook
-   (two anchored edits to phase's source). The server-side Jev relay and the browser client were not needed. Details: `farmhouse/phase/README.md`.
-Not done: the playtester's UI (no licence), a Python client for phase's WebSocket server (a large, fast-moving protocol), feeding the captured model-seat decisions into
-`scripts/farmhouse_laya_dataset.py` (the natural next step: each is an engine-issued option list plus a pick).
-
-## Risks and open questions
-- Phase is a one-person, fast-moving project: pin tags, keep a smoke test that plays a full game, expect breaking changes.
-- Rust builds are heavy; keep them in CI/containers. Resource and image size are unmeasured.
-- Card coverage is parse-level; correctness per card is unmeasured. Unsupported cards must be flagged in any result.
-- The phase server and its AI use CPU; its measured game speed is unknown (the README says a game is thousands of AI decisions).
-- Legal: phase is Apache/MIT with Wizards fan-content wording; the playtester has no licence. The card data is MTGJSON (MIT).
-- Not yet read: phase's WebSocket protocol, how `--commander-suite` accepts custom decks, and whether the server can run unattended self-play.

-## 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"

-        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")

-    conn.commit()
-    conn.close()

-if __name__ == "__main__":
-    build_index()

-
-### Step 3 — Card Enricher (`api/card_enricher.py`)
-
-```python
-import sqlite3

-DB_PATH    = Path("data/card_images.db")
-STATIC_URL = "http://localhost:8000/static/card-images"

-    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

-## Phase 4 — Commander Zone UIs

-| `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 |

-{
-    [SerializeField] private Text taxCounter;      // "Tax: +{2N}"

-
-## 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.

-
-## 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 in the cluster image
-
-The batch simulator on the Simulator page runs on **Forge**, the Java rules engine. The first cluster builds left it out by mistake ("Python-only"
-was read as "no Java"), so the page answered `Forge JAR not found`. It is now built into the image (reference copy of the Dockerfile stage:
-`infrastructure/apps/commander-lab/image/Dockerfile` in the farmhouse-os repo).
-
-What the image build does:
-
-1. **Stage 1** (`maven:3.9-eclipse-temurin-17`): fetch the official `Card-Forge/forge` at commit `edb28158f6d8` (the commit `KoalaTrapLord/Forge-Repo`
-   is on; that fork is 0 commits ahead of upstream, so this is the code the lab's Java was written against; newer Forge may have changed APIs), then
-   `mvn install -pl forge-gui-desktop -am -DskipTests -Drevision=2.0.12-SNAPSHOT`, retried up to three times (Maven Central downloads fail now and then).
-2. **The lab's Java tool** (`LabCli`, from this repository's `pom.xml`) is built against it. Forge's installed poms keep `${revision}` as their parent
-   version, which Maven cannot resolve for a consumer even with `-Drevision`; the placeholder is rewritten in the installed `.pom` files first.
-3. **Runtime**: the full `openjdk-17-jre` (not `-headless`) plus `xvfb`, the two jars, and Forge's `res/` data without `adventure`, `music`, `sound`, `quest` and `skins`
-   (about 190 MB the headless simulator never reads). The environment the app reads: `FORGE_JAR`, `FORGE_DIR`, `LAB_JAR`, `FORGE_DECKS_DIR`, `PRECON_DIR`, `JAVA_HOME`.
-4. `FORGE_MAX_THREADS` (default 1) clamps the batch's thread count: every Forge game is its own JVM with up to a 4 GB heap, and the cluster has two small nodes.
-5. CI starts the app, begins a batch through the app's own `/api/lab/start` and requires a Commander game with turns played and a readable `/api/lab/result` before the image is published.
-
-## Things that only showed up by running it in the cluster (2026-10-27)
-Each of these made a batch fail while every individual piece looked installed. Together they are why the CI test starts a batch through the app's own API.
-- **Forge needs a display, even for `sim`.** `GuiDesktop`'s static initialiser asks AWT for the default screen device; the headless JRE throws `HeadlessException`, and
-  `forge.view.Main` then exits 1 with no output at all (the lab tool records every game as an instant draw: "Forge produced NO output"). Fix: the full `openjdk-17-jre`,
-  `xvfb`, `DISPLAY=:99`, and the entrypoint starts `Xvfb :99`.
-- **Three folders, one deck.** The app writes saved decks to `USER_DECKS_DIR`, the lab's Java tool resolves deck files through `PRECON_DECKS_DIR`, and Forge finds a deck BY
-  NAME in its own commander folder ("Could not load deck"). All three are the Forge folder (`FORGE_DECKS_DIR`), which the entrypoint seeds with the 163 bundled precons.
-- **Writable folders.** The tool writes `results/` beside Forge's data and Forge a debug log beside its jar; both folders are owned by uid 10001 in the image.
-- **Result path.** The app asked for `results/ml-decision-<id>.json` (relative) but ran the tool from Forge's folder, so the file landed there and `/api/lab/result` answered
-  "Result file not found". The path is made absolute (patch `forge-results-abs`) and `/app/results` is linked to `/state/results`.
-- `docker cp` cannot write into a tmpfs and Docker mounts `/tmp` `noexec` (it stops SQLite's native library loading): test-harness traps, not cluster problems.
-
-Speed: about 25 seconds per game, one at a time (the project's own figure is ~0.04 simulations/s single-threaded). For many games with real rules, the
-phase-rs engine (`farmhouse/phase/`) is far faster. Forge is GPL-3.0: private use, do not redistribute the built image.

-# Laya as the simulator's "which action?" model: evaluation, 2026-10-26
-
-**Result: not usable as shipped.** Both checkpoints agreed with the LLM less often than a model that always answers the commonest action.
-
-## What was measured
-The simulator's LLM brain ("twin-turbo") picks one of nine actions about 25 times a game. A decision model (Laya, or Kev; both serve
-`POST /v1/systemone`) could answer that kind of question in one forward pass instead of a 7-second generation. To find out whether it
-could stand in, every LLM decision the app had recorded (`/app/logs/decisions/*.jsonl`: the game state and the action the LLM chose)
-was replayed through Laya with the same question, and the answers compared. The LLM is the *teacher*, not the truth: this measures
-whether a fast model can imitate the slow one, not which plays better.
-
-Script: `image/farmhouse_decision_eval.py` (in the app image as `/app/scripts/farmhouse_decision_eval.py`):
-`DECISION_URL=http://laya:8080 python scripts/farmhouse_decision_eval.py /app/logs/decisions english typed-decisions`
-
-## Numbers (149 recorded decisions)
-LLM's choices: play_land 41, hold 31, attack_all 28, cast_creature 20, cast_spell 13, attack_safe 7, cast_removal 5, cast_ramp 4.
-
-| | agrees with the LLM | answers | time per answer | what it picked |
-|---|---|---|---|---|
-| always "play_land" (baseline) | **27.5%** | 149 | 0 | |
-| `english` (ModernBERT-large, base) | 16.1% | 149 | 1.9 s | cast_creature 105, attack_all 26; never hold, almost never play_land |
-| `typed-decisions` (fine-tuned) | 18.6% | 140 (9 timed out at 5 s) | ~4 s (shared CPU) | cast_creature 99, attack_all 26 |
-
-It could say "cast_creature" and "attack_all" and little else; it never recognised "hold" (31 of the LLM's choices) or a removal spell.
-
-## Why, and caveats
-- The shipped checkpoints are trained on generic ticket-triage style decisions. Laya's own README says fine-tuning "on decisions from your
-  own domain is where accuracy jumps" (0.766 against 0.362 for the base on its own benchmark). This game's decisions were never in its training.
-- Speed on this cluster's CPU (4 threads) was 2-4 s per answer, not the ~33 ms quoted for a GPU. Against the LLM's ~7.5 s that is not the
-  speed-up that was hoped for either, without a GPU.
-- The question wording (the nine action descriptions) and the compact text it reads (`farmhouse_decide.compact_state`) are mine; a
-  better prompt might help a little, not from 18% to usable.
-- Part of the recorded data predates the card-data fix (v10), so some states had thinner hands than they would now.
-- The LLM being the "truth" also caps the result: where the LLM is wrong, agreeing with it is not a win.
-
-## Where this leaves it
-- Laya is **staged but scaled to 0 replicas** (`deployment-laya.yaml`: `replicas: 0`; set to 1 to run it). The image
-  (`ghcr.io/fez5587/farmhouse-laya:v1`, offline, weights baked in), the service and the network policy remain.
-- The app is wired to use it (`DECISION_URL`, `DECISION_MODE`) and `DECISION_MODE` is `off`. `shadow` records agreement without
-  affecting games; `assist` uses it when it is `DECISION_MIN_CONF` sure. Kev speaks the same API, so swapping is a URL.
-- To make it worth using: fine-tune on this game's decisions (Laya ships a Kaggle 2xT4 notebook, about 4 hours, and an Apple/CPU
-  script). The labels would be the LLM's recorded decisions; a few thousand are needed, so generate them first (LLM games at ~7 s a
-  decision, or label states with the engine's own heuristic for the cheap, abundant version). Then re-run this evaluation.
-- Node memory: it needed about 2 GB (3.6 GB with both checkpoints, which pushed the control-plane node to 92%; it is pinned to the other node).
-
-## Later the same day: the new connections (see docs/LAYA-CONNECTIONS.md in the fork)
-- **Forge-shaped priority choice** (CSIE's ranking in the text, three scenarios): agreed with CSIE each time, 42-48% sure, 7.5-8.4 s per call on the CPU against Forge's
-  1.5 s budget. Not usable on a CPU; the code falls back silently.
-- **Card roles from Oracle text** (150 unambiguous cards, 6 roles present, 9 offered): 48% against 17% by chance (counterspell 76%, board wipe 64%, removal 40%, tutor 40%,
-  ramp 36%, card draw 32%), 3.2 s per card in batches. Much better than the action choice; useful as on-demand evidence for the cards in a hand, too slow to tag the whole pool.
-- **Extra questions** in the same call: "threat" said *high* for everything; "must answer" gave 0.48 for a lethal stack against 0.25-0.29 otherwise (right direction, weak).
-- Capture, dataset export and the rest are built and off by default; fine-tuning on the captured decisions is the path to making it useful.

-# Laya in this repository
-
-Laya (https://github.com/NandhaKishorM/laya, Apache-2.0) is a **decision model**: it answers typed multiple-choice, yes/no and score
-questions about a piece of text in one forward pass and never writes text. Here it is a fast second opinion beside the LLM and CSIE.
-Kev (https://github.com/jaredpalmer/kev) serves the same `POST /v1/systemone` API, so swapping is a URL change (Kev needs a GPU).
-
-| File | What |
-|---|---|
-| `Dockerfile` | CPU image: `laya[serve]` 0.4.15 + CPU torch, English and `typed-decisions` checkpoints baked in at Hugging Face commit `7b928d8`; runs offline |
-| `deployment-laya.yaml` | Kubernetes Deployment + Service + NetworkPolicy (no egress; only the app may call it). Currently `replicas: 0` |
-| `build-farmhouse-laya.workflow.yml` | the CI workflow that builds and smoke-tests the image offline (it lives in `.github/workflows/` of the farmhouse-os GitOps repo) |
-| `LAYA-EVALUATION.md` | why it is off: zero-shot both checkpoints agreed with the LLM less often than always guessing the commonest action |
-
-The deployment source of truth is the farmhouse-os repo (`infrastructure/apps/commander-lab/`); these are reference copies so the
-fork is self-contained. Things learned running it:
-
-- A Kubernetes Service named `laya` injects `LAYA_PORT=tcp://...`, which `laya-serve` reads as its own port setting and refuses. Set
-  `enableServiceLinks: false` and `LAYA_PORT=8080` explicitly.
-- Two checkpoints resident use 3.6 GB; one uses about 1.9 GB. Do not place it on a control-plane node.
-- The CPU answers in 2-4 s, not the ~33 ms quoted for a GPU.
-- How the code in this repository connects to it, and how to fine-tune it: `docs/LAYA-CONNECTIONS.md`.

-# phase-sim: rules-accurate Commander games with phase-rs
-
-Reference copies of what runs in the cluster (source of truth: `infrastructure/apps/commander-lab/` in the farmhouse-os repo). Background and the assessment
-that led here: `docs/PHASE-AND-PLAYTESTER.md`.
-
-| File | What |
-|---|---|
-| `phase_sim.py` | the service: stdlib HTTP, one job at a time. `POST /run` four decks -> `GET /job/<id>` per-game results, wins by seat, 95% interval, warnings. Optional model seats and two loopback-only relays (`/llm/v1/chat/completions`, `/jev/systemone`) |
-| `Dockerfile` | builds phase-rs `v0.118.0` (`ai-commander`, `ai-duel`) and takes the card database that release was published with (SHA-256 checked) |
-| `Dockerfile.llm` | the same plus `ai-commander-llm`: model-driven seats |
-| `llm-seat/` | the Rust crate and the two anchored edits to phase's source that make model seats possible |
-| `phase_smoke.py`, `test_phase_sim.py` | CI: real games through the service; 49 offline checks against a stub engine |
-| `deployment-phase.yaml` | Deployment, Service and a NetworkPolicy (in: the app only; out: DNS, Olla and Laya only) |
-
-The app side is `routes/farmhouse_phase.py` (four saved decks -> the service) and `ui/phase-sim.html`; both are real source in this repository, registered by
-`lab_api.py` and linked from the home page.
-
-## Model seats: how they work and why they are safe
-phase's headless runner has no model support; the model seats exist only in phase's browser client. `phase-llm` (the crate) deliberately does no networking:
-it renders the engine's option list into a prompt, builds the HTTP request, and parses the reply, and the host performs the call. `llm-seat/` is that host
-for the headless runner:
-
-1. `apply_phase_patches.py` adds a process-wide `ACTION_OVERRIDE` hook in `phase-ai/src/auto_play.rs` (asked before the built-in AI chooses) and makes the runner's `main` `pub`.
-2. The crate `farmhouse-llm-seat` includes the runner's source as a module (`#[path]`) and installs the hook. `phase-llm` depends on `phase-ai`, so the hook cannot
-   live inside phase-ai's own binary.
-3. For each decision on a model seat: the engine issues its option list (`AiDecisionContract`); phase-llm builds the prompt (a forced move with one option is never asked);
-   this crate makes the HTTP call (blocking, no TLS, 20 s limit); phase-llm turns the reply into one of the engine's options; the choice is checked against the contract
-   here and again by `run_ai_action`. **Any** problem returns "no opinion" and phase's own AI plays the move. A cap on model calls per run (default 300) bounds the cost.
-4. The service supplies the endpoints through its own loopback-only relays: the chat relay switches the model's thinking off (twin-turbo otherwise thinks for tens of
-   seconds a move) and caps the answer; the decision relay unwraps phase's `Jev` envelope and forwards the System One request to Laya or Kev.
-
-The model never authors an action and never sees hidden cards beyond what phase-llm renders for that seat.
-
-## Status
-Written 2026-10-27. The service logic is tested offline; the Rust crate has not compiled outside CI when this was written (no Rust toolchain on the workstation), so
-its first CI run is the first real test. Check `.github/workflows/build-farmhouse-phase-sim.yml` results in the farmhouse-os repo.

-//! ai-commander with model-driven seats (FarmHouse).
-//!
-//! phase's headless runner plays four-player Commander games with the built-in AI on every seat. This binary is that same runner (its
-//! source is included below, unchanged but for `fn main` being `pub`) plus a hook, installed before the games start, that asks a
-//! language model or a decision model (Laya / Kev, over the System One protocol) to choose for the seats named in `PHASE_LLM_SEATS`.
-//!
-//! The model never authors an action. For each decision the engine issues its own option list (`AiDecisionContract`), phase-llm renders
-//! it and builds the HTTP request, this file performs the HTTP call (the one thing phase-llm leaves to the host), and phase-llm turns the
-//! reply into one of the engine's options. The pick is then checked against the contract a second time here, and again by
-//! `run_ai_action`. ANY problem (forced move, timeout, an unreadable or stale answer, the call cap) returns `None` and phase's own AI
-//! plays the move, so a model that is down, slow or wrong cannot stall or corrupt a game.
-//!
-//! Settings (environment): PHASE_LLM_SEATS "1,3" (seats 0-3; empty = none, the plain runner), PHASE_LLM_PROVIDER (OpenAiCompatible | Jev),
-//! PHASE_LLM_BASE_URL, PHASE_LLM_MODEL, PHASE_LLM_API_KEY (leave empty for http:// endpoints), PHASE_LLM_MAX_TOKENS (256),

-
-Seat i is the i-th deck in the request (P0 = first). The engine treats every seat as AI; difficulty is per seat if given.
-A game that stalls, hits the action cap, or panics is reported as such and is NEVER counted as a win or a draw.
-
-Model seats (optional, needs the image's ai-commander-llm binary): "llm_seats": [1, 3] and "llm": {"kind": "chat" | "decision", "model": "...",
-"max_calls": 300}. Those seats ask a model to pick among the ENGINE'S OWN legal options (phase-llm builds the prompt and checks the answer;
-anything wrong or slow falls back to phase's AI). kind "chat" goes to PHASE_LLM_CHAT_URL (an OpenAI-style endpoint, e.g. Olla) through this
-service's /llm relay, which switches the model's thinking off and caps its answer; kind "decision" goes to PHASE_LLM_DECISION_URL (a System One
-server: Laya or Kev) through /jev/systemone. Both relays accept connections from this machine only.

+# 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,
+      },
