[synthesis] Inability to root-cause user-reported AI failures due to lack of stack trace or deterministic logic

Log the exact system prompt, user prompt, temperature, and model version for every generation. Implement a replay debugging environment where engineers can tweak the input context to see if the failure is reproducible or a stochastic fluke.

Journey Context:
Engineers instinctively look for logs when a bug is reported. For AI, the log is just the input text and the output text. The logic is in the weights, which you cannot read. To debug, you must treat the AI as a black-box system under test. You need the exact inputs to reproduce, but since it is non-deterministic, reproduction is not guaranteed. Therefore, the debugging environment must allow rapid parameter tweaking \(temperature, context window truncation\) to isolate whether the failure was due to bad context, bad luck, or a bad model.
