Connections

• para/resources — parent node for all SE brain content
• cloud/cloud-hub — cloud infrastructure and DevOps practices that SE patterns deploy onto
• llms/ae-hub — AI engineering hub that draws on SE fundamentals for agent and pipeline design

Open Questions

• Which CS fundamentals categories have the thinnest coverage and most need new pages?
• Are there SE domains (e.g. compilers, formal verification) absent from this hub that belong here?
• How should the hub handle cross-cutting concerns like security that span multiple categories?
