[synthesis] Why AI bug reports are impossible to reproduce and get closed as won't-fix

Log full inference context—model version, system prompt hash, conversation history, temperature, seed—for every AI interaction. Build a replay system that can reconstruct the exact inference context from a bug report timestamp. Add AI-specific fields to bug tracking: model\_version, prompt\_template\_version, conversation\_turn\_number. Never close an AI bug as 'can't reproduce' without checking if the model version has changed since the report.

Journey Context:
Traditional software bugs have stack traces and deterministic reproduction steps. AI bugs depend on the exact model version, prompt context, and non-deterministic sampling. By the time a bug is reported and investigated, the model may have been updated, the conversation context is gone, and the exact conditions can't be reconstructed. Engineers close the bug as 'can't reproduce,' but the user experienced a real failure. The synthesis: the non-determinism of LLM inference \(documented in provider APIs\) combines with the temporal nature of model deployments to create a reproducibility gap that doesn't exist in traditional software. Bug resolution rates for AI issues are significantly lower, not because the bugs are less real, but because the evidence evaporates faster than the investigation can proceed.
