    def run_in_transaction(self, fn, retries: int = 12, backoff_s: float = 0.005):
        """
        Execute a callable inside a transaction with automatic retry on
        concurrent-modification conflicts.

        Mirrors the Java API's ``database.transaction(lambda)`` semantics: on
        ``ConcurrentModificationException`` / ``NeedRetryException`` the
        transaction is rolled back and ``fn`` is re-executed, with linear
        backoff. The ``with db.transaction():`` context manager cannot retry
        (a ``with`` block can't be re-entered), so use this for contended
        multi-threaded writes.

        Args:
            fn: Zero-argument callable executed inside the transaction.
            retries: Max retry attempts on conflict (default 12).
            backoff_s: Base sleep between attempts, grows linearly.

        Returns:
