- scrum-master: Sprint planning and agile process facilitation
- ux-expert: User experience optimization and usability testing
- subject-matter-expert: Domain expertise and industry standards

## Roles Removed (5)
- business-analyst → functionality split to product-owner and scrum-master
- feature-planner → merged into product-owner responsibilities
- innovation-lead → integrated into subject-matter-expert
- security-expert → integrated into subject-matter-expert
- user-researcher → merged into ux-expert

## Files Updated
### Command Files (.claude/commands/workflow/brainstorm/)
- Created: product-owner.md, scrum-master.md, ux-expert.md, subject-matter-expert.md
- Deleted: business-analyst.md, feature-planner.md, innovation-lead.md, security-expert.md, user-researcher.md
- Updated: artifacts.md, auto-parallel.md, auto-squeeze.md, synthesis.md

### Planning Templates (.claude/workflows/cli-templates/planning-roles/)
- Created: product-owner.md, scrum-master.md, ux-expert.md, subject-matter-expert.md
- Archived: Moved 5 deprecated roles to _deprecated/ with migration guide
- Added: _deprecated/README.md with deprecation details and migration paths

### Agent Configurations
- Updated conceptual-planning-agent.md with new role mappings
- Updated action-planning-agent.md with new role references

### Documentation
- Updated README.md brainstorming role tables and descriptions
- Updated README_CN.md with Chinese translations for new roles

- /workflow:brainstorm:business-analyst → use product-owner or scrum-master
- /workflow:brainstorm:feature-planner → use product-owner
- /workflow:brainstorm:innovation-lead → use subject-matter-expert
- /workflow:brainstorm:security-expert → use subject-matter-expert
- /workflow:brainstorm:user-researcher → use ux-expert
