Pull request overview
Updates the DevCycle OpenFeature provider integration to support Long evaluations by upgrading the OpenFeature Java SDK to a version that includes FeatureProvider#getLongEvaluation, and adds regression tests to validate the SDK default narrowing behavior for Double-backed numbers.
Changes:
- Bump
dev.openfeature:sdkfrom1.14.2to1.22.0. - Add
DevCycleProviderTestcoverage forgetLongEvaluation(beyond-int range success, fractional mismatch, and unsafe-range mismatch).

- This comment attributes the mismatch to precision loss, but 2^53 is exactly representable as a double. The reason it should be rejected is that it is outside the SDK’s declared safe-integer range (max 2^53−1). Updating the wording makes the test rationale accurate.
// 2^53 exceeds the double safe-integer range, so it cannot be narrowed to a long without precision loss.
Double variableValue = 9_007_199_254_740_992.0;

is there official docs about the 2^53 limitation?

Summary
Longevaluation support by upgrading the OpenFeature SDK to1.22.0.Why no custom override
DevCycle stores numbers as
Double, so the SDK default safely converts them tolongand returnsTYPE_MISMATCHfor fractional or out-of-range values. A custom override would add no capability and could remove these safeguards.
