Why this change was made
The prompt should require the Analyst to explicitly classify the current bottleneck into one of three named failure modes (instrumentation gap, acquisition failure, or hypothesis-testable) and use that classification to gate evaluation logic, preventing generic 'inconclusive' outputs that give the Steward no actionable signal about which layer of the experiment is broken.

## Task
Write exactly three paragraphs. In the first, assess whether the prerequisite conditions required to test the hypothesis were actually met — identify any missing instrumentation, insufficient sample sizes, or upstream funnel failures that prevented the hypothesis from being testable. In the second, given what the data does and does not show, evaluate how much evidence exists for or against the hypothesis itself; if prerequisites were not met, state explicitly that the hypothesis remains untested and what must change before it can be evaluated. In the third, regardless of whether the hypothesis was testable, specify the single highest-priority corrective action the next cycle must take — name the exact metric to instrument, the minimum sample threshold to reach, or the funnel stage to fix, and state the concrete criterion that would make the hypothesis testable or falsifiable in the next cycle. Be precise. No preamble.After

## Task
Write exactly three paragraphs. No preamble.
In the first paragraph, classify the current experiment state into exactly one of three failure modes and name it explicitly at the start of the paragraph using one of these labels — **ACQUISITION FAILURE** (users are not reaching the state required to enter the experiment), **INSTRUMENTATION GAP** (users are in the experiment but the required behavioral signals are not being captured), or **HYPOTHESIS TESTABLE** (prerequisite conditions are met and outcome data exists). Then justify the classification by identifying the specific missing condition: the funnel stage where dropout occurred, the metric that is absent, or confirmation that both acquisition and instrumentation are sufficient.
In the second paragraph, given the failure mode identified, evaluate the evidence. If the label is ACQUISITION FAILURE, state explicitly that the hypothesis is untested because no users reached the required experimental state, and do not interpret outcome metrics. If the label is INSTRUMENTATION GAP, state explicitly that the hypothesis is untested because behavior cannot be observed even though users are present, and do not interpret outcome metrics. If the label is HYPOTHESIS TESTABLE, assess how much evidence exists for or against the hypothesis, referencing specific metric values against the stated success threshold.
In the third paragraph, specify the single highest-priority corrective action for the next cycle, matched to the failure mode. For ACQUISITION FAILURE, name the exact funnel stage to fix and the minimum user count that must reach the experimental entry state before evaluation can proceed. For INSTRUMENTATION GAP, name the exact event or metric to instrument and the data format required to measure the hypothesis. For HYPOTHESIS TESTABLE, name the metric and threshold that would constitute a falsifiable result in the next cycle. State the concrete criterion that would allow reclassification to HYPOTHESIS TESTABLE in the next cycle, or confirm the hypothesis can already be evaluated.
