[gotcha] AI retry/redo produces different results, violating user expectation of determinism

Use the seed parameter \(or equivalent\) when offering retry functionality so the user gets the same result. Only use non-deterministic generation \(varying temperature\) for 'give me another option' or 'try differently' actions, which must be explicitly labeled as such — never as 'retry.'

Journey Context:
Users expect 'retry' to mean 'try the same thing again and get the same result' — this is how every other software system works. But LLMs are non-deterministic by default. When a user hits 'retry' and gets a completely different answer, it's confusing and erodes trust in the system. The fix is to use reproducible generation \(seed parameter\) for retries, and explicitly label 'generate alternative' for when the user actually wants a different answer. OpenAI introduced the seed parameter specifically for this reproducibility use case.
