# TASK-113-05-02: Measurement and Assertion Tool Family

**Parent:** [TASK-113-05](./TASK-113-05_Vision_Measurement_And_Assertion_Layer.md)  
**Status:** ✅ Done  
**Priority:** 🔴 High

---

## Objective

Define the deterministic truth layer that should sit under visual interpretation.

---

## Exact Documentation Targets

- `_docs/_MCP_SERVER/README.md`
- `_docs/AVAILABLE_TOOLS_SUMMARY.md`
- future tool family task docs

---

## Candidate Tool Families

- `scene_measure_distance`
- `scene_measure_dimensions`
- `scene_measure_gap`
- `scene_measure_overlap`
- `scene_measure_alignment`
- `scene_assert_contact`
- `scene_assert_dimensions`
- `scene_assert_symmetry`
- `scene_assert_containment`

---

## Acceptance Criteria

- the repo has a documented deterministic verification family to build next
- vision is clearly documented as secondary to measurement/assertion for truth
**Completion Summary:** The next deterministic truth/tool family is now explicitly defined in docs: dimensions, distance, gap/contact, overlap, alignment, proportion, symmetry, and containment.
