-## 📊 Benchmark Evaluation
-### Evaluation Status
-⚠️ **Important**: The benchmark scores previously listed in this README (76.8% HumanEval, 82.3% MBPP, 94.1% Tool Use) have been **removed pending verification**. An audit of the evaluation infrastructure revealed that:
-- **HumanEval & MBPP implementations had only 20 problems** (1-4% of full benchmarks)
-- **No proper model inference logs exist** for the claimed numbers
-- **Tool Use evaluation lacked a proper benchmark** implementation
-These scores were therefore **unverifiable** and potentially misleading.
-### Current Evaluation Framework
-We are rebuilding the evaluation infrastructure with proper methodology:
-**🔬 Recent Enhancement**: This release includes comprehensive documentation improvements, OpenRouter integration, complete tool reference (TOOLS.md), and a full evaluation audit. See [EVALUATION.md](EVALUATION.md) for details.
-1. **Official datasets**: HumanEval (164 problems), MBPP (500 problems)
-2. **Reproducible runs**: Full logs, config files, and per-problem results
-3. **Standard metrics**: Pass@1 with confidence intervals, using k≥100 samples
-4. **Transparent methodology**: All code and data publicly available
-See [EVALUATION.md](EVALUATION.md) for the full audit report and methodology.
-### Running Evaluations
-Once datasets are prepared, run proper evaluations:
-```bash
-# Download official datasets (one-time)
-python scripts/download_benchmark_datasets.py --data-dir ./data
-# Run evaluation with a model provider
-python stack_2_9_eval/run_proper_evaluation.py \
-    --benchmark humaneval \
-    --provider ollama \
-    --model qwen2.5-coder:32b \
-    --k-samples 100 \
-    --output-dir ./results/humaneval_run
 ```
-Or use the built-in CLI:
-```bash
-python stack.py --eval all --provider ollama --eval-model qwen2.5-coder:32b
-```
-### Expected Results (Base Model)
-For reference, the base Qwen2.5-Coder-32B typically scores:
-- HumanEval: ~70-72% Pass@1
-- MBPP: ~75-77% Pass@1
-Stack 2.9's fine-tuned performance will be published after proper evaluation.
----
-## 🚀 Quick Start
-### Installation
-```bash
-# Clone the repository
-git clone https://github.com/my-ai-stack/stack-2.9.git
-cd stack-2.9
-# Install dependencies
-pip install -r requirements.txt
-```
-### Hardware Requirements
-Stack 2.9 requires a GPU for optimal performance. Minimum and recommended configurations:
-| Configuration | Minimum | Recommended | Production |

+## 🏗️ Model Card
+### Base Model
+- **Architecture:** Qwen2.5-Coder-32B (32 billion parameters)
+- **Fine-tuning:** LoRA (Low-Rank Adaptation)
+- **Context Length:** 131,072 tokens
+- **Quantization:** 4-bit AWQ optional for efficient deployment
+### Training Data
+Stack 2.9 is fine-tuned on a diverse dataset including:
+- **Pattern Memory Data** (5K-10K examples): Successful interaction logs with feedback
+- **Synthetic Tool Examples** (20K+): Generated scenarios covering all 46 tools
+- **Public Datasets**:
+  - OpenAssistant (coding conversations)
+  - CodeAct (executable actions)
+  - CodeContests (competition problems)
+  - StarCoder Data (permissively licensed code)
+All data undergoes:
+- Deduplication
+- License compatibility check
+- Quality filtering (length, validity, success rate)
+### Intended Use
+✅ **Allowed:**
+- AI-assisted coding and code completion
+- Code explanation and documentation
+- Debugging and error analysis
+- Tool-use automation

+- **Licensing:** May reproduce copyrighted snippets; use license checks
+- **Tool Dependencies:** Full functionality requires OpenClaw framework
+- **Pattern Freshness:** Initial deployments have limited pattern library
+---
+## 📊 Benchmarks
+⚠️ **Important:** The benchmark scores previously listed in this README have been **removed pending verification**. An audit revealed:
+- HumanEval & MBPP implementations only had 20 problems (1-4% of full benchmarks)
+- No proper inference logs exist for claimed numbers
+- Tool Use evaluation lacked proper implementation
+These scores were **unverifiable** and have been removed.
+### Current Status
+| Benchmark | Status | Notes |
+|-----------|--------|-------|
+| **HumanEval** | Evaluation in progress | Full 164-problem suite |
+| **MBPP** | Evaluation in progress | Full 500-problem suite |
+| **Tool Use** | Benchmark development | Custom tool-calling task |
+| **GSM8K** | Not started | Math reasoning (optional) |
+We are rebuilding evaluation infrastructure with proper methodology. See [EVALUATION.md](EVALUATION.md) for the audit report and plan.
+**Expected baseline** (based on Qwen2.5-Coder-32B):
+- HumanEval: ~70-72% Pass@1
+- MBPP: ~75-77% Pass@1
+Actual fine-tuned results will be published after proper evaluation.

+# TOOLS.md - Local Notes
+Skills define _how_ tools work. This file is for _your_ specifics — the stuff that's unique to your setup.
+## What Goes Here
+Things like:
+- Camera names and locations
+- SSH hosts and aliases
+- Preferred voices for TTS
+- Speaker/room names
+- Device nicknames
+- Anything environment-specific
+## Examples
+```markdown
+### Cameras
+- living-room → Main area, 180° wide angle
+- front-door → Entrance, motion-triggered
+### SSH
+- home-server → 192.168.1.100, user: admin
+### TTS
+- Preferred voice: "Nova" (warm, slightly British)
+- Default speaker: Kitchen HomePod
+```
+## Why Separate?
+Skills are shared. Your setup is yours. Keeping them apart means you can update skills without losing your notes, and share skills without leaking your infrastructure.
+---
+Add whatever helps you do your job. This is your cheat sheet.

+# Pattern Memory Evolution
+The Pattern Memory Moat is a system for capturing, storing, and sharing code patterns across teams. It transforms individual learning into collective intelligence.
+## Table of Contents
+1. [Auto-Extraction](#auto-extraction)
+2. [Team Sync](#team-sync)
+3. [Weight Fusion](#weight-fusion)
+4. [API Reference](#api-reference)
+---
+## Auto-Extraction
+Extract patterns automatically from your Git history. The system analyzes commit messages, identifies bug fixes and features, and stores the before/after code changes.
+### How It Works
+The `extract_patterns_from_git.py` script:
+1. **Scans Git History**: Reads through commit messages and diffs
+2. **Identifies Patterns**: Uses keywords to classify commits as bug fixes or features
+3. **Extracts Context**: Captures before/after code with metadata
+4. **Stores in JSONL**: Outputs structured data suitable for training
+### Usage
+```bash
+# Extract patterns from all commits
+python scripts/extract_patterns_from_git.py \
+    --repo-path /path/to/repo \
+    --output patterns.jsonl
+# Only recent commits
+python scripts/extract_patterns_from_git.py \
+    --repo-path /path/to/repo \
+    --output patterns.jsonl \
+    --since-date "2024-01-01"
+```
+### Output Format
+Each line in the JSONL output:
+```json
+{
+  "pattern_id": "a1b2c3d4e5f6g7h8",
+  "problem_type": "bug_fix",
+  "before_code": "def buggy_function():\n    return None + 1",
+  "after_code": "def fixed_function():\n    return 1",
+  "commit_msg": "fix: handle None case in function",
+  "author": "developer@example.com",
+  "date": "2024-03-15 10:30:00",
+  "confidence": 0.85
+}
+```
+### Problem Types
+- `bug_fix`: Commits that resolve issues (keywords: fix, bug, hotfix, patch, resolve)
+- `feature_addition`: Commits that add new functionality (keywords: feat, add, implement, enhance)
+- `unknown`: Other commits (typically skipped)
+### Confidence Scoring
+The confidence score (0.0-1.0) reflects pattern quality:
+- Base: 0.5
+- +0.2 for clear bug fix keywords
+- +0.15 for clear feature keywords
+- +0.15 for having both before and after code
+- +0.1 for substantial changes (>100 chars)
+- +0.1 for large changes (>500 chars)
+---
+## Team Sync
+Share and sync patterns across your team using a shared PostgreSQL database.
+### PostgreSQL Schema
+```sql
+CREATE TABLE patterns (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    problem_type VARCHAR(50) NOT NULL,
+    solution_hash VARCHAR(64) NOT NULL,
+    code_before TEXT NOT NULL,
+    code_after TEXT NOT NULL,
+    success_count INTEGER DEFAULT 0,
+    last_used TIMESTAMP,
+    created_by VARCHAR(255) NOT NULL,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    -- Indexes
+    CONSTRAINT unique_solution UNIQUE (solution_hash),
+    INDEX idx_problem_type (problem_type),
+    INDEX idx_success_count (success_count DESC)
+);
+CREATE TABLE pattern_feedback (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    pattern_id UUID REFERENCES patterns(id),
+    user_id VARCHAR(255) NOT NULL,
+    helpful BOOLEAN NOT NULL,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+CREATE TABLE adapter_versions (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    version_name VARCHAR(100) NOT NULL,
+    adapter_path VARCHAR(500) NOT NULL,
+    created_by VARCHAR(255) NOT NULL,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    is_active BOOLEAN DEFAULT FALSE
+);
+```
+### FastAPI Endpoints
+#### GET /patterns
+List patterns with filtering and pagination.
+```bash
+curl -H "X-API-Key: your-api-key" \
+     "http://localhost:8000/patterns?problem_type=bug_fix&limit=20"
+```
+Response:
+```json
+{
+  "patterns": [...],
+  "total": 150,
+  "page": 1,
+  "per_page": 20
+}
+```
+#### POST /patterns
+Add a new pattern.
+```bash
+curl -X POST -H "X-API-Key: your-api-key" \
+     -H "Content-Type: application/json" \
+     -d '{"problem_type": "bug_fix", "code_before": "...", "code_after": "..."}' \
+     "http://localhost:8000/patterns"
+```
+#### POST /patterns/{id}/feedback
+Submit feedback on a pattern.
+```bash
+curl -X POST -H "X-API-Key: your-api-key" \
+     -H "Content-Type: application/json" \
+     -d '{"helpful": true}' \
+     "http://localhost:8000/patterns/123e4567-e89b-12d3-a456-426614174000/feedback"
+```
+### Authentication
+API key authentication via `X-API-Key` header:
+```python
+# Server-side middleware
+async def verify_api_key(request: Request, call_next):
+    api_key = request.headers.get("X-API-Key")
+    if not api_key or api_key != settings.API_KEY:
+        raise HTTPException(status_code=401, detail="Invalid API key")
+    return await call_next(request)
+```
+### Conflict Resolution
+When multiple team members contribute similar patterns:
+1. **Pattern Similarity Detection**: Hash-based deduplication
+2. **Merge Strategy**: Patterns with similar `solution_hash` are merged
+3. **Success Rate Tracking**: `success_count` increases with positive feedback
+4. **Priority**: Patterns with higher `success_count` rank higher in queries
+---
+## Weight Fusion
+Combine LoRA adapters from multiple users using weighted averaging based on success rates.
+### Algorithm
+```
+merged_weight = Σ(adapter_i.weight * adapter_i.success_rate) / Σ(success_rate)
+```
+This ensures adapters that have shown better results contribute more to the final merged adapter.
+### Merge Script Usage
+```bash
+# Basic merge with manual weights
+python scripts/merge_lora_adapters.py \
+    --adapters user1_adapter.safetensors user2_adapter.safetensors \
+    --weights 0.6 0.4 \
+    --output merged_adapter.safetensors
+# Merge using success rates (auto-computes proportional weights)
+python scripts/merge_lora_adapters.py \
+    --adapters alice_adapter.safetensors bob_adapter.safetensors \
+    --success-rates 0.85 0.65 \
+    --output team_adapter.safetensors
+# Equal weights (default)
+python scripts/merge_lora_adapters.py \
+    --adapters adapter1.safetensors adapter2.safetensors \
+    --output merged.safetensors
+```
+### Versioning
+Each merge creates a version record:
+```json
+{
+  "version_name": "v2.1-team-merge",
+  "adapter_path": "/adapters/merged_v2.1.safetensors",
+  "created_by": "alice@example.com",
+  "created_at": "2024-03-15T10:30:00Z",
+  "parent_versions": ["v2.0", "user-alice-v3", "user-bob-v2"]
+}
+```
+### Rollback
+To revert to a previous merged adapter:
+```bash
+# List available versions
+ls -la adapters/versions/
+# Restore previous version
+cp adapters/versions/v2.0.safetensors adapters/merged.safetensors
+```
+Or via API:
+```bash
+curl -X POST -H "X-API-Key: your-api-key" \
+     -d '{"version_id": "123e4567-e89b-12d3-a456-426614174000"}' \
+     "http://localhost:8000/adapters/rollback"
+```
