Contract

• open ':memory:' and assert each connection is a private database
• assert new Database(path, {}) raises SQLITE_MISUSE while new Database(path) works, because an options object resets the open flags, and that only a true access mode or a strict/safeIntegers key restores one, so { create: false } raises the same way
• assert .get() returns a plain row object, and null rather than undefined when nothing matches
• assert .all() returns an array, and an empty array when nothing matches
• assert .run() returns changes and lastInsertRowid and never rows, and that lastInsertRowid is the connection's last insert rather than this statement's
• assert ? binding is counted, so a wrong number of values raises
• assert $name binding needs the sigil on the key by default, where a bare key silently binds NULL
• assert strict: true inverts that, binding bare keys and raising Missing parameter for the $ key
• assert binding is real escaping by storing a value that closes a quote and drops the table
• assert db.query() returns one cached statement per SQL string while db.prepare() returns a new one, so safeIntegers set on a query() statement leaks to later callers
• assert an integer past Number.MAX_SAFE_INTEGER is stored losslessly but read back rounded, and is exact only with safeIntegers, as a BigInt
• assert safeIntegers as a constructor option makes every read on the connection exact, including lastInsertRowid, while changes stays a number, and that there is no Database-level safeIntegers toggle
• assert a unique constraint raises SQLiteError carrying SQLite's extended result code
• assert bun:sqlite is a builtin of the Bun runtime rather than an npm package: the Bun global is present, node:sqlite is not, and the project resolves no dependencies
