Audience Size Limits Are Visible and Fail Closed
Context
Interactive calculation needs bounded work, while full-count and exclusion totals must not masquerade as complete after truncation. Only the preview people cap is part of the cited approved milestone; additional ceilings are recorded build choices.
Decision
Report preview truncation explicitly. Reject a source or exclusion that exceeds the implemented record bound rather than returning an incomplete full result.
Alternatives Considered
Silent exclusion truncation changes recipient eligibility. Unbounded counting exceeds the limits this build currently supports.
Consequences
The preview’s people and query-record figures can be lower bounds. Count everyone removes the people cap but retains the record ceilings and task budget.
