Decision before node
The case starts from the operating constraint and the design decision, not from a list of n8n nodes.
D2 Automation Systems · Public Work
These case studies document how D2 approaches workflow orchestration, API integration, data systems, AI-assisted operations and automation infrastructure. Architecture knowledge, workflow evidence and production claims are kept explicitly separate.
The case starts from the operating constraint and the design decision, not from a list of n8n nodes.
State, ownership and evidence boundaries are made explicit before workflow execution is layered on top.
Retry, idempotency, recovery and unverified claims remain visible instead of being hidden behind a happy path.
11 public case studies
Each case states what is supported by workflow or source evidence and what is deliberately not claimed. The goal is to show how D2 thinks about systems, not to manufacture vanity metrics.
