E2E Feature Flow (LangGraph)

Scenario

Implement a secure endpoint change with full AEEF controls.

Flow

1. product-agent node creates scoped requirement.
2. architect-agent node validates design and emits handoff.
3. developer-agent node proposes patch and test artifacts.
4. qa-agent node validates test criteria.
5. security-agent node evaluates security gate.
6. platform-agent node blocks until human deployment approval.

Gate behavior

• Security gate failure routes back to developer remediation node.
• Loop limit prevents infinite autonomous retries.

Example gate payload

{
  "gate_id": "gate-security",
  "stage": "security",
  "criteria_results": [{"criterion": "no_critical_findings", "passed": true, "note": "sast clean"}],
  "decision": "pass",
  "required_human_approver": null,
  "evidence_refs": ["artifacts/security/sast-report.json"]
}
