Phase 6 cutover evidence

The owner authorized the full Phase 6 removal on 20 September 2026 after the parity, migration, integration, native PostgreSQL backup/restore, documentation, and Phase 5 browser gates passed.

Retained parity evidence

• Source archive fixture: tests/fixtures/phase6-parity-v8.json
• Source fixture SHA-256: ea2728c30b2e22d3698a3ce2453f93d4a76e048fd82d37b4ed04272ba8d9ff99
• Frozen normalized outcome: tests/fixtures/phase6-parity-expected.json
• Normalized outcome SHA-256: 9d8f60178c1d6c6fe133cf6b62c17c96a28349aaa50e60242186fff793a32bd7

TestPhase6ParityEvidence restores the source archive into a disposable PostgreSQL database and compares exports, balances, positions, goals, reports, and estate snapshots with the frozen normalized outcome. The legacy runtime is no longer required to repeat this assertion.

Post-cutover gates

The supported validation surface is:

make generate
make lint
make typecheck
make test
make migrate-check
make go-test-integration
make test-e2e-go
make build
npm run docs:build
npm run docs:capture

Native backup/restore coverage remains in internal/operator/postgres_test.go. Phase 5 browser workflows remain in tests/e2e-go/phase5.spec.ts. Legacy Drizzle migration history remains as non-executable provenance under docs/archive/drizzle-migrations.
