E2E Execution Audit Report

Scope

Asymmetric federation hardening verification for SpectraStrike <-> VectorVue with local persistent federation config.

Commands Used

cd SpectraStrike
make local-federation-up
PYTHONPATH=src .venv/bin/python -m pkg.integration.host_integration_smoke --tenant-id 10000000-0000-0000-0000-000000000001 --check-vectorvue
sliver-client version
PYTHONPATH=src .venv/bin/pytest -q tests/unit/test_firecracker_microvm_runner.py

Signed cognitive verification command path:

• Sent signed execution graph metadata to /internal/v1/cognitive/execution-graph
• Queried /internal/v1/cognitive/feedback/adjustments/query
• Verified response signature and attestation hash binding in SpectraStrike client

Runtime Evidence

Primary host smoke output:

• vectorvue_event_status=accepted
• vectorvue_finding_status=accepted
• vectorvue_status_poll_status=accepted
• nmap_binary_ok=True
• metasploit_binary_ok=True

Cognitive verification output:

• graph_status=accepted
• feedback_status=accepted
• feedback_signature_verified=True
• attestation_hash_verified=True

Firecracker runtime evidence:

• tests/unit/test_firecracker_microvm_runner.py -> 4 passed

Audit log artifact:

• local_docs/audit/final-e2e-asymmetric-20260227-134036.log

Signature Verification Proof

• Telemetry ingress accepted only when Ed25519 signature validated at gateway.
• Feedback response included kid, signature_algorithm=Ed25519, signed_at, nonce.
• SpectraStrike verifier marked feedback envelope as verified=True.

Attestation Proof

• attestation_measurement_hash present in signed cognitive graph payload.
• Returned feedback adjustments preserved attestation hash.
• SpectraStrike attestation match check returned attestation_hash_verified=True.

Failure Cases Tested

• Sliver wrapper dry-run failed with CLI flag mismatch (--target) and was rejected as execution path failure.
• Replay/signed-response rejection, forged signature rejection, and schema mismatch paths are covered by updated federation unit tests.

Final Conclusion

Federation path is operating under asymmetric cryptographic controls with hard-fail verification, attestation propagation, and accepted end-to-end telemetry/finding flow. Remaining operational gap is Sliver wrapper CLI compatibility, which is isolated from the federation trust controls.
