Both reviews landed on the same line independently. _as_role swaps the credentials in the DSN with a regex, and when the pattern does not match it returned the string unchanged. Two shapes miss it: no inline credentials, and a unix socket URL. Either one is a legal DSN. What that costs is not a broken test. The sandbox builds, every assertion still passes, and bare_dsn is now the admin connection, so the worst-case case runs the real script with --apply as a superuser against the shared table. The verifier ran that command as a dry run to see what it would have done: target public.llm_calls, 11 rows to delete. The case would still have gone red on the exit code, after the rows were gone. It raises now. There is also a second check that connects and compares current_user, because a successful string substitution is not the same as connecting as that role -- PGUSER and friends still override. The whole design rests on that connection having no grant on the shared table; a string comparison is too thin a thing to rest it on. That check has to stay inside the try. Past it the cleanup statements have already been merged into the fixture-level stack, and unwinding again runs DROP OWNED BY twice, which has no IF EXISTS. The catalog probe took any SQL and ran it on the admin connection. The design claims withholding the DSN makes the boundary structural; that was only true of the connection string, not of the capability. It takes SELECT now. --table's schema half is restricted to plain identifiers. Not a security fix, since the name goes through a parameter and _quote: the help text says complex identifiers are unsupported and the code was accepting them anyway.
