"Load-bearing" is maybe not the best example, but Claude uses these anthropomorphized decorative synonyms everywhere. Claude's structs don't have fields, they _carry_ them. Its programs don't log, they _narrate_. Its arguments are not provided on the command line, they _ride_ it. Its modules don't depend on other modules, they _sit_ on them, etc.

It doesn't mean anything at all, since any assumption that is not 'load-bearing' is irrelevant and unlikely to be discussed at all. It's just noise.

Not when "load-bearing assumption" is misused, no. "Honey, can you take the load-bearing assumption to the mechanic for an oil change?" is an example injecting the phrase into a random sentence, obfuscating the meaning of the sentence and making it more difficult to parse. LLMs do this constantly. There is no theory of mind behind how words are generated. Some phrases simply have a higher chance of being generated in various contexts, even if it doesn't make any fucking sense, and this is exacerbated by bad RLHF.
