Multi-Caller Planner

Plan how multiple Shared Storage callers share per-context contribution limits. Set each caller's desired contribution count, see how the reports are assembled, spot over-budget callers, and generate the privateAggregation.contributeToHistogram() call for each context.

Private Aggregation API requires origin trial — simulation

Chrome 134 lets Shared Storage callers set privateAggregation.setContributionLimit(n) per worklet context. Each caller can request more or fewer than the legacy fixed 20. Over-budget callers have their excess contributions dropped; under-budget callers pay less noise padding. This planner helps you allocate limits fairly across multiple callers in the same page context.
