+
+## Priority Breakdown
+
+### P2 — High Value (9 missing)
+
+These are the most impactful gaps for enterprise deployments:
+
+1. **microsoft** — MSRC advisories cover Windows/Office/Azure; major gap for Windows-heavy estates
+2. **amazon** — Amazon Linux is the default ECS/EKS base image
+3. **google** — Android/Chrome/Cloud advisories
+4. **centos** — Still widely deployed in legacy estates
+5. **fedora** — Upstream for RHEL; early-warning value
+6. **npm** — Largest package ecosystem by count
+7. **pypi** — Fastest-growing ecosystem for ML/data workloads
+8. **maven** — Dominant in enterprise Java
+9. **go** — Growing in cloud-native infrastructure
+
+### P3 — Vendor/Infrastructure (19 missing)
+
+Network vendors (fortinet, juniper, paloalto), cloud providers (aws, azure, gcp), exploit DBs, container sources, hardware vendors, niche ecosystems.
+
+### P4 — Niche/Regional (10 missing)
+
+European CERTs, CSAF/VEX federation, threat intelligence frameworks.
+
+---
+
+## Notes
+
+- Language ecosystem sources (npm, pypi, maven, go) are partially covered via OSV aggregation. Direct connectors would provide faster ingestion and richer package metadata.
+- CentOS advisories may be coverable via the existing RedHat connector with minor adaptation.
+- CSAF connector would unlock a large number of vendor advisories via the CSAF trusted provider network.
