# SCIRS2 Policy Compliance Report - OxiRS CLI

**Date**: January 7, 2026  
**Crate**: oxirs (tools/oxirs)  
**Status**: ✅ FULLY COMPLIANT

---

## Compliance Checks

### ✅ No Direct ndarray Imports
```bash
grep -rn "use ndarray::" src/ --include="*.rs"
# Result: No matches found ✅
```

**Policy**: NEVER import `ndarray` directly - use `scirs2_core::ndarray_ext`  
**Status**: ✅ COMPLIANT

---

### ✅ No Direct rand Imports
```bash
grep -rn "use rand::" src/ --include="*.rs"
# Result: No matches found ✅
```

**Policy**: NEVER import `rand` directly - use `scirs2_core::random`  
**Status**: ✅ COMPLIANT

---

### ✅ No scirs2_autograd Imports
```bash
grep -rn "use scirs2_autograd" src/ --include="*.rs"
# Result: No matches found ✅
```

**Policy**: NEVER use `scirs2_autograd` - array! macro is now in `scirs2_core::ndarray_ext`  
**Status**: ✅ COMPLIANT

---

## Proper scirs2_core Usage

### Random Number Generation

All random number generation properly uses `scirs2_core::random`:

**Files Using scirs2_core::random**:
- ✅ `src/tools/juuid.rs` - UUID generation with scirs2_core::random
- ✅ `src/tools/backup_encryption.rs` - Encryption keys with scirs2_core::random
- ✅ `src/commands/benchmark.rs` - Benchmark data generation with scirs2_core::random
- ✅ `src/commands/generate/owl.rs` - OWL instance generation with scirs2_core::random
- ✅ `src/commands/generate/shacl.rs` - SHACL-constrained data with scirs2_core::random

**Example Correct Usage**:
```rust
use scirs2_core::random::{Random, Rng, SeedableRng};

let mut rng = Random::new();
let value = rng.gen_range(0..100);
```

## Dependency Verification

```bash
cargo tree -p oxirs --depth 1 | grep scirs2
```

**Result**:
```
├── scirs2-core v0.3.0
```

✅ scirs2-core is properly included as a direct dependency

---

## Code Quality Checks

### ✅ All Tests Passing
```
cargo nextest run -p oxirs --all-features
Result: 452 tests passed, 0 failed ✅
```

### ✅ Clippy Clean
```
cargo clippy -p oxirs --all-targets --all-features -- -D warnings
Result: 0 warnings ✅
```

### ✅ Formatting Clean
```
cargo fmt -p oxirs -- --check
Result: All files properly formatted ✅
```
