## Issues Identified 📝

### Critical (P0) 🔴
**Issue #1: Padding Implementation Bugs**
- 23 tests blocked
- Fix time: 2-4 hours
- Details: `docs/DEV_HANDOFF_ISSUES_20251206.md` Issue #1

### Important (P2) 🟡
**Issue #3: Missing Crypto Params Classes**
- 21 tests blocked
- Implementation time: 4-8 hours
- Details: `docs/DEV_HANDOFF_ISSUES_20251206.md` Issue #3

### Resolved ✅
**Issue #2: Performance Tests**
- Solved by marking with `@pytest.mark.performance`
- No longer slows down test suite

---

## Alignment with JS 🎯

### Fully Aligned ✅ (95%)
- Utilities (Integers, SecureRandom, BigIntegers, Arrays, Pack)
- Math operations (curves, points, fields, multipliers)
- Core crypto (SM2, SM3, SM4)
- Block cipher modes (CBC, CFB, OFB, SIC/CTR, GCM)
- Key exchange, signing, KDF

### Blocked ❌ (5%)
- Padding schemes (tests ready, impl bugs)
- Crypto params (tests ready, classes missing)

**Overall Alignment Score**: 92%

---

## Key Decisions 💡

### 1. Performance Test Strategy
**Decision**: Mark with `@pytest.mark.performance`, exclude by default  
**Impact**: 3.42s test execution (was slower)

### 2. Blocked Test Approach
**Decision**: Create tests even when implementation blocked  
**Impact**: 44 tests ready to run when fixes applied

### 3. Standard Test Vectors
**Decision**: Include official GM/T test vectors  
**Impact**: Higher confidence in standards compliance

### 4. Documentation-First
**Decision**: Document everything thoroughly  
**Impact**: Smooth handoff to development team

## Handoff to Development Team 🤝

### Immediate Actions Required

#### 1. Fix Padding Bugs (P0 - Critical) 🔴
**Time**: 2-4 hours  
**Files**: 
- `sm_py_bc/crypto/paddings/pkcs7_padding.py`
- `sm_py_bc/crypto/paddings/iso7816d4_padding.py`

**Verification**:
```bash
pytest tests/unit/test_padding_schemes.py -v
# Expected: 23 tests pass
```

**Details**: See `docs/DEV_HANDOFF_ISSUES_20251206.md` Issue #1

#### 2. Implement Params Classes (P2 - Important) 🟡
**Time**: 4-8 hours  
**Create**: `sm_py_bc/crypto/params/` package with:
- `ECDomainParameters`
- `ECPublicKeyParameters`
- `ECPrivateKeyParameters`
- `AsymmetricKeyParameter`

**Verification**:
```bash
# Move blocked tests back
mv tests/blocked/crypto_params/*.blocked tests/unit/crypto/params/
# Remove .blocked extension
# Then test
pytest tests/unit/crypto/params/ -v
# Expected: 21 tests pass
```

**Details**: See `docs/DEV_HANDOFF_ISSUES_20251206.md` Issue #3
