I think both sets of info could be useful.

1. "Initial code generated by DubiousLLM3.0"

2. "Initial code generated by KnownGoodLLM3.0"

3. "Code checked by LLMwhichISnotFORcheckingCODE3.0"

4. "Code checked by KnownGoodLLM3.0"

These could cause the project to react:

1. "Hey, do you realise that DubiousLLM3.0 often does this job poorly?"

2. "Ok, glad to hear you used a tool that has indeed worked well in the past. Our policy is...."

3. "That tool or version is not good for checking code, so the check is mostly worthless"

4. "Thanks for having checked your code before submitting"
