Investment Flows (Sankey)

What it answers

• How does effort concentrate or fragment across themes and scopes?
• Where is the shift between delivery and reactive work?

Requirements

• Sankey must support time slicing or baseline deltas, otherwise it becomes decorative.
• Scope node (repo/team) is optional and depends on mapping availability.

Backing surfaces

• GraphQL analytics.sankey
• SQL compiler compile_sankey
