+
+The local React console brings the main workflow into one operational surface:
+
+- **Command Center**: live API and LLM status, assessment throughput, review
+  demand, remediation queues, and recent activity.
+- **Assessment Workbench**: upload project documents, choose SSDLC phase/skill,
+  inspect AI-generated risks, and complete human review.
+- **Governance Portal**: create projects, apply public framework overlays,
+  generate controls, submit evidence, and track Pallas Lens readiness.
+- **Knowledge Base**: ingest policies and standards for RAG-backed review.
+- **Agent Integrations**: expose governed MCP and A2A tools to coding agents and
+  multi-agent platforms without granting approval authority.
+- **Settings**: switch providers such as DeepSeek, OpenAI, Anthropic, Qwen, or
+  Ollama; API keys are accepted locally and only shown as masked previews.
