OmniRoute/tests/unit/cli-backup-command.test.ts

// ENVIRONMENT NOTE (sandbox better-sqlite3 / glibc limitation, not a code defect):
// This test constructs or exercises a real better-sqlite3-backed SQLite database.
// better-sqlite3 is a native addon; production and CI load it normally, but some
// sandboxes/dev boxes ship a system glibc older than the prebuilt binary requires
// ("GLIBC_2.29 not found"), so the native module fails to dlopen and any test that
// reaches better-sqlite3 directly (or asserts stdout that the load-failure warning
// would pollute) fails HERE while passing in CI. This is a known environment
// limitation, not a defect in the code under test: the OmniRoute runtime itself
// cascades to node:sqlite/sql.js when better-sqlite3 is unavailable. See
// tests/unit/_helpers/betterSqlite3Availability.ts for a guard helper.
