The register defined 46 requirements and zero tests, so every Done in it rested on inspection. This adds the T1 tier: an xUnit project in the solution, covering the two units whose logic is pure enough to test without a Jellyfin host. JR-022 (UT-001..006) covers the cases where removal could reach too far -- another plugin's injection, and an unmarked look-alike script tag -- because index.html is a file JRay shares. UT-001 pins the trailing newline to the tag, without which every install cycle leaves another blank line behind. JR-016 (UT-007..011) covers specificity resolution, including the prioritised series inside an ignored genre that motivated the rule, and a Series rule valued Guid.Empty, which would otherwise swallow every movie in the library. RemoveInjection is reached through InternalsVisibleTo rather than being made public: it is factored out for testability, not part of the surface. The suite BUILDS but does not RUN here. Jellyfin.Controller framework- references Microsoft.AspNetCore.App, so the test host demands it even for pure logic, and this machine has no ASP.NET Core runtime at any version -- RollForward cannot substitute for a framework that is absent entirely. Fix is to install aspnet-runtime, which the CI image needs for the same reason. So every UT here is recorded as Written, not Passing, and no requirement is promoted to Done on their strength. A test whose result nobody has seen is not evidence.
