+# Optimized Multi-Source Discovery Runner
+
+## Overview
+
+The `optimized_runner.rs` example demonstrates a high-performance multi-source data discovery pipeline using RuVector's SIMD-accelerated vector operations, parallel data fetching, and statistical pattern detection.
+
+## Features
+
+### 1. **Parallel Data Fetching** (tokio::join!)
+Fetches data from multiple sources concurrently:
+- **PubMed**: Medical/health literature via E-utilities API
+- **bioRxiv**: Life sciences preprints
+- **CrossRef**: Scholarly publications metadata
+- **Synthetic Data**: Climate and research vectors for testing
+
+```rust
+let (pubmed_result, biorxiv_result, crossref_result) = tokio::join!(
+    fetch_pubmed(&pubmed, "climate change impact", 80),
+    fetch_biorxiv_recent(&biorxiv, 14),
+    fetch_crossref(&crossref, "climate science environmental", 80),
+);
+```
+
+### 2. **SIMD-Accelerated Vector Operations**
+Uses AVX2 instructions when available (4-8x speedup):
+- Cosine similarity with SIMD intrinsics
+- Falls back to chunked processing on non-x86_64
+- Batch vector insertions with rayon parallel iterators
+
+### 3. **Memory-Efficient Graph Building**
+- Incremental graph updates (avoids O(n²) recomputation)
+- Cached adjacency matrices
+- Parallel similarity computation via rayon
+
+### 4. **Discovery Pipeline Phases**
+
+#### Phase 1: Parallel Data Fetching
+- Concurrent API calls to all sources
+- Automatic fallback to synthetic data if APIs fail
+- Target: 200+ vectors from mixed domains
+
+#### Phase 2: SIMD-Accelerated Graph Building
+- Batch insert vectors with parallel processing
+- Pre-allocated data structures
+- Target: 1000+ vectors in <5 seconds
+
+#### Phase 3: Incremental Coherence Computation
+- Min-cut algorithm with cached adjacency matrix
+- Early termination for small cuts
+- Real-time coherence updates
+
+#### Phase 4: Pattern Detection with Statistical Significance
+- P-value computation using historical variance
+- Cohen's d effect size calculation
+- 95% confidence intervals
+- Granger-style causality analysis
+
+#### Phase 5: Cross-Domain Correlation Analysis
+- Domain-specific coherence metrics
+- Temporal causality detection
+- Bridge pattern identification
+
+#### Phase 6: Export Results
+- CSV export for patterns with evidence
+- Hypothesis report generation
+- GraphML export for visualization (optional)
+

+
+## Code Architecture
+
+### Key Functions
+
+- `fetch_all_sources_parallel()`: Parallel API calls with tokio::join!
+- `generate_synthetic_data()`: Fallback data generation
+- `simd_cosine_similarity()`: AVX2-optimized vector comparison
+- `analyze_cross_domain_correlations()`: Statistical correlation analysis
+- `export_results()`: CSV and report generation
+
+### Optimizations
+
+1. **Parallel Batch Insert**
+   ```rust
+   #[cfg(feature = "parallel")]
+   engine.add_vectors_batch(vectors); // Uses rayon internally
+   ```
+
+2. **Incremental Adjacency Matrix**
+   ```rust
+   // Cached and only recomputed when dirty
+   let adj = if self.adjacency_dirty {
+       self.build_adjacency_matrix()
+   } else {
+       self.cached_adjacency.clone().unwrap()
+   };
+   ```
+
+3. **Early Termination**
+   ```rust
+   // Stop min-cut early if cut is very small
+   if best_cut < early_term_threshold {
+       break;
+   }
+   ```
+
+4. **SIMD Intrinsics**
+   ```rust
+   #[cfg(all(target_arch = "x86_64", target_feature = "avx2"))]
+   unsafe {
+       let va = _mm256_loadu_ps(a.as_ptr().add(offset));
+       let vb = _mm256_loadu_ps(b.as_ptr().add(offset));
+       dot = _mm256_fmadd_ps(va, vb, dot);
+   }
+   ```
+
+## Benchmarking
+
+The example includes integrated benchmarking:
+
+1. **Phase Timing**: Each phase reports duration
+2. **Throughput Metrics**: Vectors/sec and edges/sec
+3. **SIMD Microbenchmark**: 10,000 cosine similarity comparisons
+4. **Target Achievement**: Comparison vs target metrics
+
+## Extending the Example
+
+### Add New Data Sources
+
+```rust
+// In fetch_all_sources_parallel():
+let arxiv = ArxivClient::new();
+
+let (pubmed, biorxiv, crossref, arxiv_result) = tokio::join!(
+    fetch_pubmed(...),
+    fetch_biorxiv(...),
+    fetch_crossref(...),
+    fetch_arxiv(&arxiv, "machine learning", 50),
+);
+```
+
+### Custom Pattern Detection
+
+```rust
+// Add custom pattern types in Phase 4
+let custom_patterns = detect_custom_patterns(&engine);
+patterns.extend(custom_patterns);
+```
+
+### Enhanced Exports
+
+```rust
+// Add GraphML export in Phase 6
+use ruvector_data_framework::export::export_graphml;
+
+let graph_file = format!("{}/graph.graphml", output_dir);
+export_graphml(&engine, &graph_file)?;
+```
+
+## Performance Tips
+
+1. **Use Release Mode**: ~10x faster than debug
+   ```bash
+   cargo run --example optimized_runner --release
+   ```
+
+2. **Enable Target CPU Features**: Unlocks AVX2/AVX-512
+   ```bash
+   RUSTFLAGS="-C target-cpu=native" cargo build --release
+   ```
+
+3. **Tune Batch Size**: Adjust in OptimizedConfig
+   ```rust
+   let config = OptimizedConfig {
+       batch_size: 512, // Increase for larger datasets
+       ...
+   };
+   ```
+
+4. **Increase Similarity Cache**: For larger graphs
+   ```rust
+   similarity_cache_size: 50000, // Default: 10000
+   ```
+
+## Troubleshooting
+
+### API Rate Limits
+If you hit rate limits, the example automatically falls back to synthetic data. To avoid this:
+- Add API keys to client constructors
+- Reduce fetch limits
+- Increase delays between requests
+
+### Out of Memory
+For very large datasets:
+- Reduce `batch_size`
+- Process in chunks
+- Disable similarity caching
+
+### Slow Performance
+- Ensure `--release` flag is used
+- Check `use_simd: true` in config
+- Verify `parallel` feature is enabled

+# Real Data Discovery Example
+
+This example demonstrates RuVector's discovery engine on **real academic research papers** fetched from the OpenAlex API.
+
+## What It Does
+
+Fetches actual climate-finance research papers across multiple topics:
+- **Climate risk finance** (20 papers)
+- **Stranded assets** (15 papers)
+- **Carbon pricing markets** (15 papers)
+- **Physical climate risk** (15 papers)
+- **Transition risk disclosure** (15 papers)
+
+Then runs RuVector's discovery engine to detect:
+- Cross-topic bridges (papers connecting different research areas)
+- Emerging research clusters
+- Consolidation/fragmentation trends
+- Anomalous coherence patterns
+
+## Running the Example
+
+```bash
+cd examples/data/framework
+cargo run --example real_data_discovery
+```
+
+## Example Output
+
+```
+╔══════════════════════════════════════════════════════════════╗
+║     Real Climate-Finance Research Discovery with OpenAlex    ║
+║              Powered by RuVector Discovery Engine            ║

+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+📡 Phase 1: Fetching Research Papers from OpenAlex API
+
+   Querying topics:
+   • climate risk finance: fetching 20 papers... ✓ 20 papers
+   • stranded assets energy: fetching 15 papers... ✓ 15 papers
+   • carbon pricing markets: fetching 15 papers... ✓ 15 papers
+   ...
+
+   Total papers fetched: 80
+```
+
+## Features
+
+### Real API Integration
+- Uses OpenAlex's public API (no authentication required)
+- Polite API usage with rate limiting
+- Graceful fallback to synthetic data if API fails
+
+### Semantic Analysis
+- Simple bag-of-words embeddings (128-dim)
+- Converts paper titles + abstracts to vectors
+- Preserves citation and concept relationships
+
+### Discovery Engine
+- **Graph construction**: Builds semantic graph from paper embeddings
+- **Coherence computation**: Dynamic minimum cut algorithm
+- **Pattern detection**: Multi-signal trend analysis
+  - Cross-topic bridges
+  - Emerging clusters
+  - Research consolidation/fragmentation
+  - Anomaly detection
+
+### Performance
+- Processes ~8 papers/second
+- Handles 50-100 papers comfortably
+- Scalable to larger datasets with optimized backend
+
+## API Rate Limits
+
+OpenAlex allows polite API usage without authentication:
+- ~10 requests/second with polite headers
+- Built-in retry logic for rate limit errors
+- Automatic fallback if API unavailable
+
+To be extra polite, the client includes an email in requests (configurable in the code).
+
+## Customization
+
+### Fetch Different Topics
+
+Edit the `queries` vector in `main()`:
+
+```rust
+let queries = vec![
+    ("topic_id", "your search query", 20),  // 20 papers
+    ("another_topic", "another query", 15), // 15 papers
+];
+```
+
+### Adjust Discovery Thresholds
+
+Modify the `DiscoveryConfig`:
+
+```rust
+let discovery_config = DiscoveryConfig {
+    min_signal_strength: 0.01,    // Lower = more patterns
+    emergence_threshold: 0.15,     // Cluster growth threshold
+    bridge_threshold: 0.25,        // Cross-topic connection threshold
+    anomaly_sigma: 2.0,            // Anomaly sensitivity
+    ..Default::default()
+};
+```
+
+### Change Coherence Settings
+
+Adjust the `CoherenceConfig`:
+
+```rust
+let coherence_config = CoherenceConfig {
+    min_edge_weight: 0.3,          // Similarity threshold
+    window_size_secs: 86400 * 365, // Time window (1 year)
+    approximate: true,             // Use fast approximate min-cut
+    ..Default::default()
+};
+```
+
+## Understanding Results
+
+### Cross-Topic Bridges
+Papers that connect different research areas. High bridge frequency indicates interdisciplinary research.
+
+```
+🌉 Cross-Topic Bridges: 3
+   1. Climate risk papers bridging to finance literature
+      Confidence: 0.85
+      Entities: 12 papers
+```
+
+### Emerging Clusters
+New research areas forming over time. Indicates novel directions.
+
+```
+🌱 Emerging Research Clusters: 2
+   1. Emerging structure detected: 5 new nodes over 3 windows
+      Strength: Moderate
+```
+
+### Consolidation/Fragmentation
+Shows whether topics are converging or diverging.
+
+```
+📈 Consolidating Topics: 1
+   • Strengthening trend detected: 3.2% per window
+```
+
+## Extending the Example
+
+### Use Advanced Embeddings
+
+Replace `SimpleEmbedder` with a real embedding model:
+
+```rust
+// Instead of SimpleEmbedder
+use sentence_transformers::SentenceTransformer;
+
+let model = SentenceTransformer::load("all-MiniLM-L6-v2")?;
+let embedding = model.encode(&text)?;
+```
+
+### Integrate with RuVector Core
+
+Use `ruvector-core` for production vector search:
+
+```rust
+use ruvector_core::HnswIndex;
+
+let mut index = HnswIndex::new(128)?;
+for record in &records {
+    if let Some(embedding) = &record.embedding {
+        index.insert(&record.id, embedding)?;
+    }
+}
+```
+
+### Export Results
+
+Save discoveries to JSON:
+
+```rust
+use std::fs::File;
+use std::io::Write;
+
+let json = serde_json::to_string_pretty(&patterns)?;
+let mut file = File::create("discoveries.json")?;
+file.write_all(json.as_bytes())?;
+```
+
+## Troubleshooting
+
+### API Errors
+If you see frequent API errors:
+1. Check your internet connection
+2. The example will automatically fall back to synthetic data
+3. For large queries, add delays between requests
+
+### No Patterns Detected
+This is normal with small datasets! Try:
+1. Fetching more papers (increase limits)
+2. Lowering thresholds in `DiscoveryConfig`
+3. Fetching more diverse topics to find bridges
+
+### Out of Memory
+For large datasets:
+1. Reduce the number of papers fetched
+2. Use the `approximate` coherence engine
+3. Process in batches

+//! cross-domain patterns across multiple data sources:
+//! - OpenAlex (research papers)
+//! - PubMed (medical literature)
+//! - NOAA (climate data)
+//! - SEC EDGAR (financial filings)
+//!
+//! This example demonstrates:
+//! - Climate-health connections (heat waves → hospital admissions)
+//! - Finance-health connections (pharma stocks → drug approvals)
+//! - Research-health connections (publications → clinical trials)
+//! - Climate-finance-health triangulation
+//!
+//! The discovery engine builds a unified coherence graph and detects
+//! novel patterns across domain boundaries.
