Jellyfin 12 moved to net10.0, so the shipped 3.3.6.0 build does not load on it at all. And the part of this plugin that rewrites API responses — the MediaSourceResultFilter that filters PlaybackInfo and item payloads — is exactly the kind of surface that breaks at call time across an ABI jump, and it has not been validated against 12. What we actually need on Jellyfin 12 today is the intro provider, so users can be assigned policies and get their per-policy intro safely.

This makes 3.4.0.0 an intro-only build:

  • PluginServiceRegistrator now registers only IIntroProvider. The MediaSourceResultFilter registration (scoped service + global MVC filter via PostConfigure<MvcOptions>) is gone; the filter file stays in the tree, inert, so re-enabling later is a two-line registration plus re-validation.
  • Api/QualityGateController.cs is deleted. Its only job was MediaSource filtering, the admin page never calls it (it uses the built-in plugin-configuration and user endpoints), and controllers mount by assembly scanning, so unregistering was not an option. It also held the riskiest server call (IMediaSourceManager.GetPlaybackMediaSources).
  • Version 3.4.0.0, targetAbi 12.0.0.0, net10.0, with Jellyfin packages pinned to 12.0.0-rc5 — the exact version prod runs — instead of floating. CI moved to the .NET 10 SDK and net10.0 artifact path; the release job's manifest entry now writes ABI 12.0.0.0.
  • Registrator tests rewritten to assert the intro provider is the only registration (they fail if anyone re-adds the filter without deciding to); controller tests removed with the controller. Policy assignment from the admin page keeps working — policies and per-user assignments are what the intro provider reads.

Verified: dotnet build -c Release clean (0 warnings) and all 142 tests pass against 12.0.0-rc5/net10.0. Grepped the surviving code for the known 10.11→12 call-time traps: no PrimaryVersionId usage; the compile against the exact rc5 packages checks every remaining server-API signature. Not deployed anywhere.

The plugin targets .NET 10 and Jellyfin ABI 12. Package versions, build paths, plugin version, manifest metadata, and changelog entries were updated.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 65a80

The plugin behavior is now intro-only, but tagged releases would still advertise media-version filtering until the generated release description is updated. This is a bounded documentation and user-expectation risk; the PR is otherwise mergeable with that follow-up.

Jellyfin 12 moved to net10.0, so the 3.3.6.0 build does not load there,
and the MediaSource filtering path (result filter rewriting PlaybackInfo
and item responses) has not been validated against the new ABI — response
rewriting is exactly where the old middleware approach broke, and where
call-time ABI surprises would land.

Ship only the part that must survive: the policy-based intro provider.
Stop registering MediaSourceResultFilter (the file stays in the tree,
inert, for later re-validation) and delete the QualityGate API controller
— its only job was MediaSource filtering, the admin page never calls it
(it uses the built-in plugin-configuration and user endpoints), and
controllers mount by assembly scanning so unregistering was not an option.
Policy and user assignment in the admin page keep working and drive intro
selection.

Version 3.4.0.0, targetAbi 12.0.0.0, net10.0, packages pinned to
12.0.0-rc5 to match the server. Registrator tests now assert the filter
stays unregistered; controller tests removed with the controller.
142 tests pass.
