portability

Overview ¶

Package portability holds the cross-engine plugin fixtures that keep the PostgreSQL and SQLite adapters honest about the same behavior: baseline migration, real factor/tenant/credential data preserved across disablement, and re-enablement after an upgrade. The fixtures require a real engine, so they build only under the integration tag; run them with scripts/check.sh plugins-sqlite or the PostgreSQL integration job. See docs/adapter-authoring.md for the contract they enforce.
