I also saw something similar happen with other OSes before, like here for UBI
lucacome/nginx-ubi#247 9.5 -> 9.6-1745489786

That's not the expected behavior.

Even if Renovate wanted to change from the number to the codename for some reason, it shouldn't add the date. I don't want it to be pinned to a specific date.

Any chance that it can be converted to an issue?

Yeah, this is unwanted behaviour for me as well. I have disabled Debian patch updates to prevent this from happening.

    "packageRules": [
        {
            "matchPackageNames": ["debian"],
            "matchUpdateTypes": ["patch"],
            "enabled": false
        }
    ]
