chore: close duplicate Milestone 2 registry prototype

+## Added
+
+- Added a normalized, aggregate-only provenance root for private PostgreSQL
+  analysis runs, downstream TEPP/contextual-orchestrator/fast-mlsirm service
+  calls, status events, and external acceptance artifacts.
+- Added a no-future-information database and Python contract requiring the
+  source snapshot's latest evidence-availability time not to exceed the run's
+  knowledge cutoff.
+- Added deterministic, source-redacting request digests and transactional
+  idempotency/conflict handling without storing SQL, DSNs, raw content, image
+  bytes, provider credentials, or private source identifiers.
+- Added real-PostgreSQL schema tests and 100% statement/branch coverage for the
+  new Python contracts and repository.
+
+## Security
+
+- Private actual-data acceptance manifests remain external deployment
+  artifacts referenced only by digest and URI; public API projections contain
+  aggregate counts, clocks, opaque IDs, configuration, and status only.
