+# Communicate in Spatial Context
+
+| Epic | Delivery status | Status source | Owner | Approved for Solution |
+|---|---|---|---|---|
+| `3DARCH-EP-5` | `IN_BACKLOG` | `EXACT` | 3D Architecture Wizzard team | No |
+
+## Goal
+
+Enable floor-scoped text with speech bubbles and push-to-talk voice with proximity-reflective volume and speaking indicators.
+
+## Benefit
+
+People can coordinate through visible text and natural nearby conversation in the context where they are working.
+
+## Problem or opportunity
+
+Participants need fast written and spoken communication without leaving the shared 3D environment.
+
+## Constraints
+
+- Only materially implemented legacy behavior is included; planned-only capabilities remain outside the approved catalogue.
+
+## Features
+
+No child Features have been defined or approved. Feature discovery must preserve this Epic boundary and requires a separate human **Approved for Solution** decision before Architecture solution work begins.
