## Review Summary

**Cross-Compilation Infrastructure**: HIGH QUALITY

### Files Created
1. **`scripts/build-linux.sh`** - Local cross-compilation script
   - cargo-zigbuild integration
   - Binary verification (ELF 64-bit check)
   - Size validation (<30MB requirement)
   - Debug symbol stripping
   - Error handling and colored output

2. **`.github/workflows/build-bootstrap.yml`** - Automated CI builds
   - Builds on push to main and PRs
   - Fast setup with cargo-binstall
   - Binary validation and artifact upload
   - 30-day artifact retention
   - GitHub Actions summary output

### Strengths
1. **Robust build script**:
   - Checks for cargo-zigbuild and zig
   - Validates binary format and size
   - Proper error handling (`set -euo pipefail`)
   - Clear logging with colors

2. **Efficient CI workflow**:
   - Cargo caching (registry, git, target)
   - Fast cargo-zigbuild install via cargo-binstall
   - Binary verification steps
   - Artifact upload for deployment

3. **Deployment ready**:
   - Binary stripped for optimal size
   - Format validation ensures Linux compatibility
   - Clear next steps in script output

### Quality Checks

**Build Script Security**: ✅ PASS
- No hardcoded credentials
- Proper error handling
- Safe file operations

**CI Workflow Security**: ✅ PASS
- Uses official actions (checkout@v4, cache@v4, upload-artifact@v4)
- No secrets exposure
- Proper artifact retention policy

**Task Completion**: ✅ PASS
- All requirements implemented:
  - ✅ cargo zigbuild command
  - ✅ Binary output path validation
  - ✅ Debug symbol stripping
  - ✅ Binary format verification
  - ✅ GitHub workflow automation

---

## Findings

### MINOR Issues (0 blocking)

None. Implementation follows best practices.

---

## Consensus Verdict

**VERDICT**: ✅ PASS

**Justification**:
- Zero critical or important issues
- Rust codebase unaffected (all builds/tests pass)
- Cross-compilation infrastructure production-ready
- Task 4 requirements fully met
- CI automation properly configured

**Action Required**: NO

---

## Task Specification Compliance

**Task 4 Requirements**:
- ✅ Use cargo zigbuild → Implemented in both script and workflow
- ✅ Binary output path → Validated in script
- ✅ Strip debug symbols → Implemented
- ✅ Verify static linking → ldd check (Linux only)
- ✅ GitHub workflow → Complete with caching and artifacts

**Grade**: A (100%)
