The most minimal IronClaw attestation flow isn't about the enclave code itself, but about proving its identity from the outside. The "hello world" is a verifier that receives a quote and validates it against the platform's attestation service. Forget the complex multi-step tutorials; the core is a single, well-instrumented verification call.

Here is the absolute baseline using the IronClaw Python SDK. This assumes you already have a quote, typically acquired from the client's `get_attestation_evidence()` call within the enclave and transmitted over your secure channel.

```python
from ironclaw.verifier import AttestationVerifier
from ironclaw.exceptions import AttestationFailedError

# Initialize the verifier for your specific attestation service (e.g., Azure DCAP)
verifier = AttestationVerifier(
service="azure",
# In production, you'd use a proper configuration for your root of trust
attestation_endpoint="https://sharedwus.us.attest.azure.net"
)

# `raw_quote` is the binary quote bytes received from the client
# `runtime_data` is the expected public data (e.g., a public key hash) you pre-register
try:
attestation_result = verifier.verify_quote(
quote=raw_quote,
expected_runtime_data=expected_public_key_hash,
enforce_policy=True
)
except AttestationFailedError as e:
# Quote was invalid, enclave is not trustworthy
print(f"Attestation failed: {e}")
return

# If we reach here, the enclave's TEE identity is cryptographically proven.
print(f"Enclave MRENCLAVE: {attestation_result.mrenclave.hex()}")
print(f"Enclave MRSIGNER: {attestation_result.mrsigner.hex()}")
print(f"TCB security version: {attestation_result.tcb_info}")
```

The crucial part happens inside `verify_quote`. IronClaw abstracts the heavy lifting: fetching the latest TCB (Trusted Computing Base) info and certificate revocation lists from the attestation service, validating the quote's signature chain, and finally checking that the `report_data` field contains the hash of your expected `runtime_data`. If any link in that chain is broken—a revoked platform certificate, a compromised TCB version, or mismatched runtime data—the exception is thrown.

A compromised attestation chain in practice would manifest here. For example, if an attacker managed to poison the local DCAP service or proxy, the verifier might receive forged TCB info, making a vulnerable platform appear secure. That's why, for production, you must harden the verifier's network path to the attestation service and consider using your own cached root certificates. This snippet is the starting point; the real work is in the observability you build around its failure modes.
