If I delay upgrading to the latest Bitcoin Core version post Taproot activation does my node ever verify early Taproot spends?

Let’s assume the Taproot soft fork is activated in June 2021. I continue to run an old version of Bitcoin Core (not enforcing Taproot rules) in July 2021 and so my full node treats valid Taproot spends as anyone-can-spend. Then in August 2021 I upgrade to the latest version of Bitcoin Core and start enforcing the Taproot rules. Does my full node re-verify the Taproot spends from the point of activation or does it only verify Taproot spends from the point that I upgraded to the latest version of Bitcoin Core?
