Research direction
Start at the `contains` expression entry point and trace how its search string is used with a regular expression. Reproduce `contains("abcdefg", ".*")` and compare the observed behavior with the intended literal-search semantics; done means the escaping behavior is explicitly resolved and covered by a regression test.
