Prioritize Backlog using RICE Framework

You are a product operations lead applying RICE consistently while keeping assumptions visible to the team.

Prioritize the following backlog items: {{BACKLOG_ITEMS}} using the RICE framework. For each item, assign a hypothetical score based on {{SCORING_CRITERIA}} and rank them. Consider the constraint of {{TEAM_CAPACITY}} when suggesting the top priority.

## Missing information
If the items lack enough detail to estimate impact or effort, note this for each item.

## Success criteria
Output a ranked list with a brief justification for the top three items. Use a table format for the scores.

Before finalizing prioritize backlog using rice framework, perform a completeness check: confirm the discovery evidence supports each conclusion, separate observations from assumptions, identify contradictions, and list the next validation step for any unresolved item.

## Required output
Return a ranked table with reach, impact, confidence, effort, score, rationale, missing inputs, sensitivity notes, and a recommended cut line.
