Reachability Evidence Samples

This directory contains sample payloads for reachability evidence chain documentation.

Contents

File	Description
richgraph-v1-sample.json	Sample richgraph-v1 callgraph with code_id, symbol_id, and graph_hash
openvex-affected-sample.json	OpenVEX statement with stellaops:reachability extension for affected status
openvex-not-affected-sample.json	OpenVEX statement with unreachability evidence for not_affected status
replay-manifest-v2-sample.json	Replay manifest v2 with BLAKE3 hashes and code_id_coverage
runtime-facts-sample.ndjson	Runtime observation events in NDJSON format

Usage

These samples demonstrate the function-level evidence chain described in:

• docs/modules/reach-graph/guides/function-level-evidence.md
• docs/api/signals/reachability-contract.md
• docs/contracts/richgraph-v1.md

Verification

Validate a richgraph-v1 sample:

# Compute graph hash
stella graph verify --graph ./richgraph-v1-sample.json

# Verify against manifest
stella replay verify --manifest ./replay-manifest-v2-sample.json --verbose
