Directory.Build.targets

<!--
  This file is imported late in the build order. Use it to override properties
  and define dependent properties.

  Per-project Flowthru reference injection (PackageReference→ProjectReference swap,
  Core/FUnit analyzer wiring, FUnit constants) is NOT handled here for projects
  that explicitly import build/FlowthruInRepoSwap.props (and optionally
  build/FlowthruFUnit.props). Those projects own their own swap logic.

  The remaining unmigrated test projects under tests/ that don't import
  FlowthruInRepoSwap.props (most of tests/core, tests/extensions, tests/misc) use
  direct <ProjectReference> to Flowthru/Flowthru.Core in their csprojs and rely
  on the Core/FUnit targets being imported here so that analyzers get registered.
  This block is migration-scope only — it shrinks as more test projects adopt
  FlowthruInRepoSwap.props.

  <PropertyGroup>
    <MSBuildProjectDirRelativePath>$([MSBuild]::MakeRelative($(RepoRoot), $(MSBuildProjectDirectory)))</MSBuildProjectDirRelativePath>
    <NodeModulesRelativePath>$([MSBuild]::MakeRelative($(MSBuildProjectDirectory), $(RepoRoot)))</NodeModulesRelativePath>
  </PropertyGroup>

  <!-- Determine whether this project already imports FlowthruInRepoSwap.props (in
       which case the analyzer wiring is already handled by that file). We can't
       inspect imports directly, so we set a marker property in FlowthruInRepoSwap
       and check for it here. The check is conservative: if the marker is unset
       (not migrated), we fall back to the legacy global Core/FUnit imports below. -->

  <!-- Legacy fallback: register Core source generators for unmigrated tests/ projects
       that still rely on global injection. Once all tests/ projects import
       FlowthruInRepoSwap.props, this block can go away. -->

    Central coverage configuration: any project identified as a test project by
    Microsoft.NET.Test.Sdk automatically uses coverlet.runsettings, regardless of
    how dotnet test is invoked (IDE, CLI, or NX target). This removes the need to
    pass collect and settings flags on every call site. Individual test projects
    can override this by setting their own RunSettingsFilePath in PropertyGroup
    (e.g., Flowthru.Tests.Examples uses a project-local runsettings file).
