I am confused about the behavior of the check-block command. I was expecting it to re-execute the block, but it seems like this is not the case.

For example, the following command:

āžœ  ~ RUST_LOG=runtime=trace,executor=trace,info ./polkadot check-block --database paritydb --base-path ... --wasm-runtime-overrides ./wasm --chain kusama 0x7a0fcaf6fde9be14aeaf57b84a95f4286ba8d9435bd9c5426a1fbfd0954e8bd6

2022-12-12 16:58:15.286  INFO main wasm_overrides: Found wasm override. version=kusama-9340 (parity-kusama-0.tx17.au2) file=./wasm/kusama_runtime.wasm

Interestingly, the executor logs show that Core_execute_block runtime API was not called.

My goal is to re-execute the previous block(s) with a --wasm-override that does NOT have the runtime logs disabled, so I can see all the runtime logs.

So, the real question is, what is check-block even doing, and if it is not the above requirement, what alternative exist? try-runtime-cli has a command that can also execute past blocks, but it is a bit harder to work with.
