Matched evidence windows

Compare representatives

Put separate evidence lenses side by side while retaining the denominator, unknowns, exclusions, source limits, and service eligibility behind every number. This is not a ranking of effort, effectiveness, or value.

How fair comparison works

The server accepts only two to four unique members, requires one metric window available to all of them, verifies identical calendar dates and metric definition versions, and labels cross-chamber rates as not directly comparable.

Same-chamber selections are directly comparable when the server confirms one window and definition set.
