Graph-40k fixture (SAMPLES-GRAPH-24-003)

Canonical large SBOM graph fixture with policy overlay for performance/regression suites.

Contents

  • nodes.ndjson — 40,000 component nodes (pkg:pypi/demo-*) for tenant demo-tenant.
  • edges.ndjson — 100,071 DEPENDS_ON edges (fan-out ≤4, DAG order).
  • overlay.ndjson — 100 policy.overlay.v1 records with verdict/severity + optional edge to policy rule node.
  • manifest.json — counts and SHA-256 hashes.
  • verify.py — offline verifier for hashes/counts.

Determinism

  • Fixed seed 424242, snapshot graph-40k-policy-overlay-20251122, timestamp 2025-11-22T00:00:00Z.
  • Sorted NDJSON rows, stable overlay ID scheme sha256(tenant|nodeId|overlayKind).
  • Generated via samples/graph/scripts/generate_canonical.py (no network access).

Verify

cd samples/graph/graph-40k
python verify.py

Regenerate (optional)

python ../scripts/generate_canonical.py --out-dir samples/graph/graph-40k

Ensure manifest hashes match after regeneration before promoting to offline kits.
