---

### Task Specification (Grade: A)

**Issues Found:** 0 critical, 0 high, 0 medium, 0 low

✅ **11/11 acceptance criteria met** - 100% spec compliance
✅ **MachineKeypair implemented** - Complete with all required methods
✅ **AgentKeypair implemented** - Complete with all required methods
✅ **Identity struct implemented** - Pre-implemented from Task 6
✅ **No unsafe/unwrap/expect** - In production code

## Code Changes Analyzed

**Files modified in Tasks 4-6:**
- `Cargo.toml` - Added `hex = "0.4"` dependency
- `src/identity.rs` - Code formatting improvements

**Changes:**
