# Case studies

> Dated, reproducible studies of PolyNode performance, coverage, and production behavior.

PolyNode case studies test a concrete product claim against a defined denominator. Each study records its date, endpoints, subscription semantics, source versions, measurement clock, eligibility window, adverse observations, and limitations.

## Evidence standard

Every benchmark case study should:

* define equivalent signals before measuring them;
* timestamp all competitors from the same monotonic clock and process;
* use an independent completeness denominator when one exists;
* exclude partially observed boundary intervals;
* preserve per-sample data, missing identifiers, source hashes, and connection lifecycle events;
* report unfavorable windows and unavailable comparisons;
* separate measured results from broader product claims;
* publish code with credentials supplied only at runtime.

These are point-in-time measurements, not guarantees about every network location or future provider version.
