Purpose
Present BOTH sides with dates and methods (#3.1) - the brief's credibility rests on not smoothing.
When to use
After trend-compare whenever contradictions[] is non-empty.
Inputs
compared.json.
Steps
- Quote each contradiction verbatim: which studies, which directions, which methods, which periods.
- Offer the honest framings (method difference, period difference, real reversal) as QUESTIONS for the insight manager, not conclusions.
Output
Contradiction section for the brief.
Grounding requirements
Both studies cited fully.
Constraints
- No midpoint averaging, no "on balance" verdicts; causal attribution is out of scope (#5.1).
Escalation / uncertainty
Contradiction on the question's core metric -> insight-manager review before the brief ships.
