Architectural notes on agent orchestration, data engineering, control boundaries, and system evolution.
Node Monitoring and Timeline Replay for the Smart Cockpit Agent
Addressing the practical debugging question of whether an agent actually called downstream APIs, using an ordered event stream for live node monitoring and frontend prefix replay while handling loop span pairing, SSE subscription races, and thread limits.
Orchestrating Agent Workflows with State Graphs in the Smart Cockpit
Starting from why a single prompt struggles with multi-step business logic, this article walks through Graph-based state models, tool loops, multi-specialist collaboration, and how customer-service workflows connect to Coding Agents and cybernetics.
Business Ledger and Agent Interaction Design for 3D Smart Parking
Reusing the Enterprise AI Cockpit backend, a reproducible year of synthetic parking records, server-side role checks, a versioned POI road graph, and AG-UI events connect a fullscreen 3D campus to parking recommendations, work orders, analytics, and voice/vision controls.
Engineering a 3D Parking Twin for Desktop and Mobile
A fullscreen, detailed campus twin with shared vehicle geometry, conservative mobile LOD, sharp rendering, contextual overlays, and reliable static deployment.
Sub2API Gateway Internals and Enterprise Agent Architecture
A source-level study of streaming proxying, account-pool scheduling, atomic Redis concurrency control, multi-level authentication caching, and idempotent billing in Sub2API.
Knowledge Engineering and Tunable Cockpit Architecture for Enterprise RAG
A deep dive into enterprise RAG knowledge engineering: structure-aware chunking, hybrid Dense+Keyword retrieval with RRF reranking, lifecycle metadata governance, MCP boundaries, and the Retrieval Lab evaluation loop.
