Naive funded_by linking over-merges. A conservative policy restores interpretable structure.
Historical baseline (naive funded_by policy)
Shared infrastructure (routers, high-fanout funders) creates artificial connectivity, producing a giant mixed cluster.
Naive: funded_by → merge · Conservative: funded_by → gated evidence
The giant cluster disappears. Smaller, interpretable clusters emerge.
