Do those phrases sound like how you talk to Claude? I've found that it mirrors my verbiage, and I have never seen any of those.
I go through ~20B tokens/month and I've never seen "genuinely happy... but not comfortable" or your other examples.
The closest I've seen (fairly often is) "I *will not* ship to main with a red test", but that's close to how I write. Claude may well be mirroring your speech patterns rather than exposing trained-in language.
It's not my patterns – as I said, this is from bulk tests to characterise the models, including their refusals – with very very different inputs, too. No matter the conversation tone, you get these.
You wouldn't have come across these in coding – these are more for 'things Anthropic's team have decided aren't acceptable enough for their taste'.
