# MongoDB → PostgreSQL Conversion Summary
Date: 2025-12-05
Status: COMPLETE

## Completed Modules
- Authority — Postgres-only; verification: `docs/db/reports/authority-verification-2025-12-03.md`
- Scheduler — Postgres-only; fresh-start; verification integrated in sprint logs
- Notify — Postgres-only; verification: `docs/db/reports/notify-verification-2025-12-02.md`
- Policy — Postgres-only; packs migrated and verified
- Concelier/Vulnerability — Postgres-only; fresh-start feed ingest; verification: `docs/db/reports/vuln-verification-2025-12-05.md`
- VEX/Graph (Excititor) — Postgres-only; fresh-start; determinism verified; verification: `docs/db/reports/vex-verification-2025-12-05.md`
- Issuer Directory — Postgres-only; fresh-start (CSAF seed); verification in sprint 3409 log

## Foundations
- Postgres infra library, migrations, CI Testcontainers: DONE
- Cluster and persistence configs captured: `docs/db/cluster-provisioning.md`, `docs/db/persistence-config-template.yaml`

## Schemas
- Exported: authority, scheduler, notify, policy, vuln, vex
- Exported: issuer, shared audit (approved; issuer migration executed)

## Strategy Notes
- Fresh-start applied to Scheduler, Vuln, VEX/Graph, Issuer (no Mongo backfill); data populated via feeds/runtime/CSAF seed.
- Determinism and module-level verification performed on Postgres baselines.

## Remaining Optional Items
- Monitor growth (vuln/vex) and consider partitioning/perf tuning as data scales.
