// Regression guard for the substring bug: eleven subsystems decided "am I under a test runner?" with
// `process.argv.some((a) => a.includes("test"))`. JavaScript agrees that 'latest'.includes('test') is
// true, so ANY argv carrying a `latest` path segment — a release symlink like /opt/app/latest/server.js,
// an npm cache path, a `--model=latest` flag — silently put the process into "test mode". For
// src/lib/db/backup.ts that means isSqliteAutoBackupDisabled() returns true: no SQLite auto-backup, no
// warning. Same class for migrationRunner, cloud sync, health checks and quota recovery.
//
// argv/env are parameters (not read off the global) precisely so this file can assert the negative
// cases — under the test runner the globals always say "test", which is what made the bug invisible.
