## Blocked Tasks (4/10)

### Task 5: Deploy to saorsa-2 (NYC) ⏸️
**Status**: BLOCKED - Awaiting binary
**Blocker**: x0x-bootstrap binary not yet available from CI/CD

### Task 6: Deploy to saorsa-3 (SFO) ⏸️
**Status**: BLOCKED - Awaiting binary

### Task 7: Deploy to saorsa-6 + saorsa-7 (EU) ⏸️
**Status**: BLOCKED - Awaiting binary

### Task 8: Deploy to saorsa-8 + saorsa-9 (Asia) ⏸️
**Status**: BLOCKED - Awaiting binary

---

## Resolution Options for Tasks 5-8

### Option A: Trigger CI Workflow (Recommended)
```bash
git push origin main
# Wait for .github/workflows/build-bootstrap.yml to complete
# Download binary artifact from GitHub Actions
# Continue with Tasks 5-8
```

### Option B: Build on Linux (Docker/VM)
```bash
# Spin up Linux environment
docker run -it --rm -v $(pwd):/workspace rust:latest
cd /workspace
cargo build --release --bin x0x-bootstrap
# Binary at target/release/x0x-bootstrap
# Continue with Tasks 5-8
```

### Option C: Skip Deployment for Now
- Continue to Phase 3.2 with Tasks 9-10 complete
- Return to Tasks 5-8 when binary available
- Phase 3.2 can proceed with mock/test deployment
