+Cost Allocation Engine for MarkiTect Issue Cost Distribution.
+
+This module implements the core allocation engine that distributes operational
+costs across active issues using the defined algorithm from Issue #88.
+
+The engine handles:
+- Equal distribution of costs across active issues in a period
+- Loss carried forward when no active issues exist
+- Transaction audit trail creation
+- Edge case handling and validation
+- Integration with period management and activity tracking

+Tests for Issue #114 - Cost Allocation Engine Implementation
+
+This module contains comprehensive tests for the cost allocation engine

+
+Tests cover:
+- Core allocation algorithm with equal distribution
+- Edge cases (no active issues, no costs, closed periods)
+- Transaction audit trail creation
+- Loss carried forward handling
+- Integration with existing cost and activity tracking
+- CLI command functionality
+- Allocation reversal capabilities
