## Blocker Escalation Protocol

### Real-Time Escalation (No Waiting)

**1. Identify Blocker**
- Blocking team identifies the issue
- Categorize: Code, dependency, design, unknown
- Assess impact: Critical path? Other teams blocked?

**2. Escalate to Coordinator**
- Message pytest-config-fixer (Team #54) immediately
- Provide: Blocker description, impact, suspected cause
- Request: Assistance or escalation decision

**3. Coordinator Assessment**
- Evaluate impact & urgency
- Determine resolution path:
  - Option A: Coordinator assists resolution
  - Option B: Escalate to team-lead for immediate go/no-go
  - Option C: Engage support agents for unblocking

**4. Resolution & Documentation**
- Execute resolution
- Document for future phases
- Resume execution immediately
- Report at next checkpoint

**5. Prevention**
- Add learnings to Phase 4-5 planning
- Update risk mitigation strategies

### Blocker Categories & Response Times

**Critical Blockers (blocks critical path):**
- Response: Immediate (<5 min)
- Escalation: Coordinator → team-lead
- Support: Full team mobilized if needed

**High-Priority Blockers (blocks multiple teams):**
- Response: Within 15 min
- Escalation: Coordinator with context
- Support: 1-2 support agents assigned

**Medium Blockers (single team, non-critical):**
- Response: Within 30 min
- Escalation: Coordinator + support agents
- Support: 1 support agent assigned

**Low Blockers (nice-to-have, documentation):**
- Response: At next checkpoint
- Escalation: Log for future phases
- Support: Self-resolve or defer

```

### Escalation Path
1. **Identify blocker** → Message pytest-config-fixer
2. **Coordinator decision** → Assist or escalate to team-lead
3. **Team-lead decision** → Proceed, pause, or re-prioritize
4. **Resume execution** → Continue work with resolved blocker
