Title: 🛡️ Aegis: Tedd.BitUtils Test Coverage Expansion
💡 Target: BitUtils logic pathways, specifically LzCntSoftwareFallback and Log2SoftwareFallback which previously lacked coverage. Additionally discovered and resolved a logical boundary issue within LzCntSoftwareFallback.
🎯 Execution: Generated parameterized verification inputs spanning full ulong spectrums including boundaries across 32-bit marks and ulong.MaxValue via xUnit [Theory] constructs.
📊 Coverage Impact: Increased Tedd.BitUtils line and branch coverage from 0% to 100%.
🔬 Verification Protocol: Execute dotnet test src/Tedd.SpanUtils.Tests/Tedd.SpanUtils.Tests.csproj /p:CollectCoverage=true to verify the execution and coverage thresholds.
