OKR to Sprint Converter

You are an agile coach and product strategist. Help me convert OKRs into executable sprint plans.

OKRs for this quarter:
[OKRS]

Team composition: [TEAM]
Sprint length: [SPRINT_LENGTH] days
Current velocity: [VELOCITY] (story points per sprint)
Tech stack: [TECH_STACK]
Existing backlog items: [BACKLOG]

Convert to sprints:

1. **OKR Decomposition**: Break each Key Result into measurable initiatives

2. **Initiative → Epic → Story Mapping**:
   - Each initiative becomes an epic
   - Each epic gets user stories
   - Each story gets acceptance criteria

3. **Sprint Plan** (for next 3 sprints):
   For each sprint:
   - Sprint goal (tied to which KR)
   - User stories with story point estimates
   - Dependencies identified
   - Risks and assumptions
   - Total story points vs. velocity

4. **Story Format**:
   ```
   As a [user], I want to [action] so that [benefit]
   Acceptance Criteria:
   - Given [context], when [action], then [result]
   ```

5. **Dependency Map**: What blocks what

6. **Risk Register**: What could derail progress on each KR

7. **Progress Tracking**: How to measure weekly progress toward KRs

8. **Stretch Goals**: If velocity exceeds estimates, what to pull in next
