Why: The U3 migration must replace the target schema seed with the source directory revision and cursor key. Evidence: Isolated PostgreSQL TestMigrateEndToEndAndIdempotent passed with field-by-field source and target comparison. Impact: Migration regressions that lose directory cursor identity now fail the existing end-to-end test. Refs: IAM U3 Stage 7; docs/proposals/2026-10-14-iam-u3-account-contract-and-plan.md §10
