rUv 38d93a6e8d feat: Add comprehensive dataset discovery framework for RuVector (#104)
* feat: Add comprehensive dataset discovery framework for RuVector

This commit introduces a powerful dataset discovery framework with
integrations for three high-impact public data sources:

## Core Framework (examples/data/framework/)
- DataIngester: Streaming ingestion with batching and deduplication
- CoherenceEngine: Min-cut based coherence signal computation
- DiscoveryEngine: Pattern detection for emerging structures

## OpenAlex Integration (examples/data/openalex/)
- Research frontier radar: Detect emerging fields via boundary motion
- Cross-domain bridge detection: Find connector subgraphs
- Topic graph construction from citation networks
- Full API client with cursor-based pagination

## Climate Integration (examples/data/climate/)
- NOAA GHCN and NASA Earthdata clients
- Sensor network graph construction
- Regime shift detection using min-cut coherence breaks
- Time series vectorization for similarity search
- Seasonal decomposition analysis

## SEC EDGAR Integration (examples/data/edgar/)
- XBRL financial statement parsing
- Peer network construction
- Coherence watch: Detect fundamental vs narrative divergence
- Filing analysis with sentiment and risk extraction
- Cross-company contagion detection

Each integration leverages RuVector's unique capabilities:
- Vector memory for semantic similarity
- Graph structures for relationship modeling
- Dynamic min-cut for coherence signal computation
- Time series embeddings for pattern matching

Discovery thesis: Detect emerging patterns before they have names,
find non-obvious cross-domain bridges, and map causality chains.

import matplotlib.pyplot as plt
plt.plot(coherence['timestamp'], coherence['mincut_value'])
plt.xlabel('Time')
plt.ylabel('Min-Cut Value')
plt.title('Network Coherence Over Time')

Advanced Usage

Custom Export Pipeline

use ruvector_data_framework::export::*;

// 1. Export full graph
export_graphml(&engine, "full_graph.graphml", None)?;

// 2. Export each domain separately
for domain in [Domain::Climate, Domain::Finance, Domain::Research] {
    let filter = ExportFilter::domain(domain);
    let filename = format!("{:?}_graph.graphml", domain);
    export_graphml(&engine, &filename, Some(filter))?;
}

// 3. Export significant patterns only
let significant_patterns: Vec<_> = patterns.iter()
    .filter(|p| p.is_significant)
    .cloned()
    .collect();
export_patterns_csv(&significant_patterns, "significant_patterns.csv")?;

// 4. Export time-windowed coherence
let recent_history: Vec<_> = coherence_history.iter()
    .rev()
    .take(100)
    .cloned()
    .collect();
export_coherence_csv(&recent_history, "recent_coherence.csv")?;

Performance Considerations

  • Large Graphs: Use filters to reduce export size
  • GraphML: XML parsing can be slow for >100K nodes
  • DOT: Graphviz rendering slows down at >10K nodes
  • CSV: Very efficient for patterns and coherence data

Future Enhancements

The export module currently provides a foundation. To access the full graph data (nodes and edges), the OptimizedDiscoveryEngine will need to expose:

pub fn nodes(&self) -> &HashMap<u32, GraphNode>
pub fn edges(&self) -> &[GraphEdge]
pub fn get_node(&self, id: u32) -> Option<&GraphNode>

Once these methods are added, the GraphML and DOT exports will include actual node and edge data.
