PolylineKit 0.1.0-alpha.3

Published on NuGet.org: PolylineKit.Core and the optional Clipper adapter.

Both signed public archives preserve all original payload entries. Four fresh NuGet.org-only consumers passed on .NET 8 and .NET 10; both repository signatures and gallery READMEs were verified after indexing.

PolylineKit 0.1.0-alpha.3 delivers cheaper polygon-role preparation without public API, assembly-name or runtime dependency changes. Core remains dependency-free; the optional adapter still uses Clipper2.

Well-conditioned rings use a guarded compensated orientation sum; tiny, cancelling or uncertain inputs retain the previous route. The intersection engine is unchanged. The contour demo now has real browser regressions and fixes the inclusive 0.7% budget conversion.

Preparation measurements remain pinned to a7cad8a, not these new binaries. The Helsinki assessment still describes the actual alpha.2 package and retains its failed three-way gate; it is not an alpha.3 accuracy or speed claim.

Both original packages were verified from clean source 23c0b3280424569356d64362266c519c839b4790 with four outside-checkout consumers on .NET 8 and .NET 10. Packages are uploaded unchanged, with verification.json and SHA256SUMS. See the release notes for delivery checks and numerical limits.
