+/**
+ * Postgres-backed end-to-end exercise of the Better-Auth adapter.
+ *
+ * The test stands up a real Postgres 16 container via
+ * `@suaveplan/testing-integration-postgres`, applies Better-Auth's
+ * documented schema (user / session / account / verification tables), wires
+ * a real Better-Auth instance against the connection, and verifies the
+ * register → login → resolve-protected-route flow.
+ *
+ * The schema is applied by hand-rolled DDL because Better-Auth's migration
+ * generator runs as a CLI step out-of-band of the runtime; embedding the
+ * canonical table definitions inline keeps the test self-contained.
+ *
+ * When the Postgres fixture cannot start (no Docker daemon, no testcontainers
+ * download, runner pinned to a sandbox without Docker), the suite logs a
+ * SKIP marker and exits — the runtime-level invariants are pinned by
+ * `src/session/*.test.ts`, `src/provider/*.test.ts`, and the
+ * conformance test files, all of which run without external infrastructure.
