# Rejected Alternatives — Economics

Rejected proposals in the **economics** domain, rationale preserved for the audit trail.

### R-011: Single currency for Phase 2 economics
- **Rejected:** 2026-04-05
- **Proposed by:** Burnelli-Sheldon (economist), Sprint 32 Workshop T-796 Round 1
- **Proposal:** Use a single currency for the Phase 2 economics simulation to reduce model complexity; exchange-rate mechanics could be added in a later phase.
- **Reason:** Three currencies create structural economic bloc tension as an emergent property of initialization, requiring no event generation. The Tractus/Mark divide maps directly to the canonical Assembly vs. Compact political divide. Deferring to a later phase would require retrofitting political geography into a running simulation. Complexity cost low; design value high.
- **Raised by:** Lead directive overruling the recommendation.
- **Cross-reference:** [D-171 (economics.md)](../decisions/economics.md#d-171-three-currency-system)
