I don't think trusted state captures the nuance well.
It's a much weaker trust assumption than that confers.

You're verifying that you've received exactly the same Blockchain data that the network had buried by at least a month of pow at the release of the software, and if that's the case, you assume that you'll find the scripts to have been valid. You still check most of the block rules, tx rules, just not the result of evaluating the scripts.
You did check that the scripts are byte-by-byte exactly the same though.
