+# ReachGraph
+
+> Unified store for reachability subgraphs with edge-level explainability.
+
+## Purpose
+
+The ReachGraph module provides a unified store for reachability subgraphs, enabling fast, deterministic, audit-ready answers to "exactly why a dependency is reachable." It consolidates data from Scanner, Signals, and Attestor into content-addressed artifacts with edge-level explainability.
+
+## Quick Links
+
+- [Architecture](./architecture.md) - Technical design and implementation details
+- [Guides](./guides/) - Usage and query guides
+- [Schemas](./schemas/) - ReachGraph schema definitions

+## Status

+| Attribute | Value |
+|-----------|-------|
+| **Maturity** | Production |
+| **Last Reviewed** | 2025-12-29 |
+| **Maintainer** | Scanner Guild, Signals Guild |
+
+## Key Features
+
+- **Unified Schema**: Extends PoE subgraph format with edge explainability
+- **Content-Addressed Store**: All artifacts identified by BLAKE3 digest
+- **Slice Query API**: Fast queries by package, CVE, entrypoint, or file
+- **Deterministic Replay**: Verify that same inputs produce same graph
+- **DSSE Signing**: Offline-verifiable proofs
+
+## Dependencies
+
+### Upstream (this module depends on)
+- **Scanner** - CallGraph data source
+- **Signals** - ReachabilityFactDocument source
+- **Attestor** - PoE JSON source
+
+### Downstream (modules that depend on this)
+- **Policy Engine** - Reachability-based policy evaluation
+- **Web Console** - Reachability visualization
+- **CLI** - Reachability queries
+- **ExportCenter** - Reachability data exports
+
+## API Endpoints
+
+- `POST /v1/reachgraphs` - Create new reachgraph
+- `GET /v1/reachgraphs/{digest}` - Retrieve reachgraph by digest
+- `GET /v1/reachgraphs/{digest}/slice` - Query slice of reachgraph
+- `POST /v1/reachgraphs/replay` - Verify deterministic replay
