+# Seed Service Implementation
+
+This directory contains the seed service implementation for Story 1.9: "Seed System Reference Values & Rule Defaults".
+
+## Implementation Plan
+
+The seed service will:
+
+1. **Seed Reference Values**
+   - Operational status values
+   - Service template defaults
+   - Extension-layer reference values
+
+2. **Configure Required-Field Rules**
+   - Default readiness fields for election-cycle jobs
+   - Evaluation capability for Epic 2's readiness status feature
+
+3. **Set Up Escalation Rule Defaults**
+   - Default rules covering overdue milestone alert scenarios
+   - FR30 compliance
+
+4. **Ensure Idempotency**
+   - Seed operation is fully idempotent
+   - No duplicate records on multiple runs
+
+5. **Maintain Separation**
+   - Admin-managed values persist independently
+   - Seed does not overwrite admin changes
+
+## Files
+
+- `ISeedService.cs` - Interface defining seed service contract
+- `SeedService.cs` - Implementation of seed service
+
+## Implementation Notes
+
+In a complete implementation, this service would:
+- Interact with a database context
+- Check if seeding has already occurred
+- Create seed data with proper constraints
+- Handle idempotent operations
+- Be registered in the DI container
