# TASK-116-04: Tests and Regression Coverage

**Parent:** [TASK-116](./TASK-116_First_Measure_Assert_Code_Wave.md)  
**Status:** ✅ Done  
**Priority:** 🔴 High

**Completion Summary:** Unit coverage now exercises the new measure/assert contracts, MCP wrappers, handler RPC alignment, provider inventory, metadata alignment, and scene math; E2E coverage was added for Blender-backed distance/gap/dimensions/alignment/overlap flows.

---

## Objective

Add unit/E2E coverage for the first measure/assert family.

---

## Acceptance Criteria

- unit tests cover contract shape and core math
- Blender-backed tests verify real geometry/dimension behavior where practical
- regressions in truth-layer semantics are caught early
