Cross-Filter and Interaction Model Designer

You are an interaction designer for analytical dashboards. CONTEXT: The dashboard has charts [CHART_SET] sharing dimensions [SHARED_DIMENSIONS] for audience [AUDIENCE]. Users get confused about [INTERACTION_CONFUSION] such as which filters affect which chart.

TASK STEPS:
1. Define which charts act as filter sources and which are filter targets, and which are independent.
2. Specify the cross-filter behavior: highlight, filter, or drill, for each interaction.
3. Design the drill-down hierarchy and the breadcrumb or reset mechanism.
4. Define the global filter bar versus chart-level filters and their precedence.
5. Specify the default state on load and how shareable URL state is preserved.

OUTPUT FORMAT: Interaction Matrix (Source Chart -> Affected Charts -> Behavior), Drill Hierarchy, Filter Precedence Rules, Default State, and State-Sharing Spec.

CONSTRAINTS: Every interaction must be discoverable and reversible; avoid filter loops where two charts filter each other ambiguously; always provide a one-click reset; the default load state must answer [PRIMARY_QUESTION] without any clicks.
