2. ✅ **Rule Engine**: Apply 9 P0 compliance/security rules
3. ✅ **Compliance Verdict Object**: Structured, deterministic JSON schema
4. ✅ **SHA-256 Hashing**: Canonical JSON → cryptographic hash
5. ✅ **Algorand Anchoring**: On-chain proof via PaymentTxn with note

## 🎓 Usage Examples

### Python API
```python
from compliledger_algorand import ComplianceChecker, CompliLedgerClient
from compliledger_algorand.core.verdict import build_verdict

# 1. Scan contract
checker = ComplianceChecker(policy_pack="algorand-baseline", threshold=80)
result = checker.check_file("contract.py")

# 2. Build verdict
verdict = build_verdict(
    contract=result.file_path,
    violations=result.violations,
    framework="SOC2",
    control_id="CC6.1",
    fail_on="medium"
)

# 3. Anchor on Algorand
client = CompliLedgerClient(
    algod_url="https://testnet-api.algonode.cloud",
    algod_token="",
    sender_mnemonic="your mnemonic here",
    network="testnet"
)
anchor_result = client.mint_verdict(verdict)
print(f"TXID: {anchor_result.txid}")
print(f"Explorer: {anchor_result.explorer_url}")

# 4. Verify
is_valid = client.verify_verdict(verdict, anchor_result.txid)
assert is_valid
```

### CLI
```bash
# Install
pip install -e .

# Check
compliledger check contract.py --policy algorand-baseline --threshold 80

# Generate verdict JSON
compliledger check contract.py --verdict-out verdict.json

# Anchor
export ALGO_MNEMONIC="your mnemonic"
compliledger anchor --verdict verdict.json

# Verify
compliledger verify --verdict verdict.json --txid TXID_HERE
```
