🤖 Boromir triage — PR #282

Summary of changes (effective diff against current dev):

• Directory.Packages.props: MongoDB.Driver 3.6.0 → 3.8.0 ✅ valid
• src/AppHost/AppHost.csproj: adds <PackageReference Include="MongoDB.Driver" /> ⚠️ spurious

Why CI is blocked:

Same root cause as #281: subsequent "Merge branch dev" merge commits were pushed by github-actions[bot], which doesn't trigger CI. The initial commit (dbbe64ae) ran CI but failed at dotnet restore.

Root cause of restore failure (initial commit):

The restore failure on the initial commit is most likely caused by the AppHost.csproj change. AppHost is an Aspire orchestration project — it uses Aspire.Hosting.MongoDB for orchestration and does not call into MongoDB.Driver types directly. Adding an explicit <PackageReference Include="MongoDB.Driver" /> to AppHost.csproj is incorrect; the driver is a transitive dependency of Aspire.Hosting.MongoDB and does not belong as a direct reference here.

There may also be a version-range incompatibility between MongoDB.Driver 3.8.0 and Aspire.Hosting.MongoDB 13.3.0 that surfaces only when the reference is made explicit in the AppHost, which would explain the dotnet restore failure.

Recommended action:

@dependabot recreate

This will produce a clean PR that only touches Directory.Packages.props. If the version bump itself is compatible with Aspire.Hosting.MongoDB 13.3.0, CI will pass. If not, the failure will be a clear restore/compat error on the NuGet change alone — at which point we can either ignore the bump until Aspire ships compatibility or pin appropriately.
