Thanks Kartik. Tone changes were the single biggest source of regressions for us, which is why rule 2 (a regression blocks until explained) exists at all.

On your question: a document-issue tag by itself does not become a case, because the suite tests the bot, not the corpus. Those go to the content owner as a governance item. It becomes a case when the tag exposes a behaviour gap: for example the bot answered confidently from outdated material when the correct output was “the document does not say”. That failure is the bot’s, so it gets a case and a weight. Roughly, document issues feed the content backlog, and the bot’s reaction to bad documents feeds the suite.
