[synthesis] Standard post-mortems cannot reproduce AI failures

Replace 'reproduction steps' with an 'uncertainty budget' and immutable input/output/trace logs; design post-mortems around distribution shift, prompt context, and outlier replay rather than deterministic root cause.

Journey Context:
SRE culture requires reproducible failures to verify fixes. LLMs and many ML models are intentionally stochastic, and even fixed-weight inference can vary with temperature, context length, tool results, and vendor-side changes. A failure that happened once may never recur, so chasing a single root cause wastes time. The synthesis is that AI incidents are distribution-level events, not point failures; post-mortems must analyze the conditions under which failure probability spiked, not the single unlucky output.
