Contradiction Flag

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

1. Quote each contradiction verbatim: which studies, which directions, which methods, which periods.
2. 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.
