Start here
Choose the layer that matches what the issue now needs.
Use Services when the issue is already live and needs clearer decision criteria, stronger review, more workable role boundaries, or direct support in context.
Use Knowledge when a smaller reusable step is enough for scope, context, and practical working structure before heavier support is needed.
Use Writing when the next useful move is better framing, sharper language, or a clearer understanding of what is actually blocked.
Use Contact when the issue is real but the right starting point is still hard to define cleanly.
