## Political Economy Overlay

### Activation
Apply this overlay when `literature-mapper` is used for political economy questions about institutions, actors, incentives, distributional conflict, policy, state capacity, or economic outcomes.

### Required Context
- Require the focal political economy debate, institution type, actor set, policy or economic outcome, method family, and target venue.
- Require adjacent literatures in economics and political science before mapping the conversation.
- Require the focal mechanism and at least two rival mechanisms.

### Subject-Specific Procedure
1. Organize literature by political mechanism, not only by topic or geography.
2. Separate institutional origins, actor incentives, distributional conflict, policy process, and economic outcome literatures.
3. Map whether each paper provides theory, measurement, causal evidence, mechanism evidence, or historical context.
4. Identify where the user's project changes an existing debate rather than merely applying it to a new case.
5. Mark rival mechanisms and evidence gaps that the study design must answer.

### Reviewer-Risk Checks
- Check whether the map collapses economics, political science, and policy literatures into a broad summary.
- Check whether canonical institution or state-capacity work is cited without specifying the mechanism being borrowed.
- Check whether the claimed gap is just a missing country, sector, or time period.

### Output Requirements
- The literature map must include `Debate`, `Mechanism`, `Institution`, `Actors`, `Outcome`, `Evidence Type`, and `Gap`.
- The output must name the target political economy conversation and the rival conversation a reviewer may invoke.
- Missing mechanism or boundary-condition literature must be recorded as a search gap.

### Blocked Conditions
- Block a contribution claim when the map cannot identify the political economy debate being changed.
- Block mechanism claims when the literature only supports outcome association.
- Do not treat policy relevance as a substitute for scholarly positioning.
