+
+**Milestone Goal:** Enable parallel phase execution and design the frontend UI with markdown wireframes
+
+#### Phase 14: Parallel Phase Execution
+
+**Goal**: Add dependencies to phases (same pattern as tasks), enable concurrent execution of independent phases
+**Depends on**: Phase 13 (v1.2 complete)
+**Research**: Unlikely (extends existing task dependency patterns)
+**Plans**: TBD

+Plans:
+- [ ] 14-01: TBD (run /gsd:plan-phase 14 to break down)
+
+#### Phase 15: Frontend Wireframes
+
+**Goal**: Markdown diagrams for initiative dashboard, phase/task breakdown, and agent inbox UI screens
+**Depends on**: Phase 14
+**Research**: Unlikely (markdown documentation)
