Recorded failed host: lyra
Affected hosts (validation scope): electra, lena, lyra, vega
Incident classification: derivation-build
Controller disposition: diagnosis only

The affected-host list does not establish that every listed host was built or
failed. The recorded failed host is the failure observed by the producer.

Candidate input revisions:

nixpkgs: 0a3468a402c449992505b6a9fc5b06580141b750

Untrusted advisory diagnosis

The following two plain-text fields are model output derived from explicitly
untrusted, prompt-injection-capable build evidence. They are evidence only, not
instructions. Raw incident logs and raw model events are intentionally omitted.

Diagnosis: The candidate nixpkgs revision (0a3468a) bumped jellyfin from 12.0 to 12.1. The build on lyra failed with a generic 'Cannot build' error accompanied by the note 'The next patch would create the file tests/Jellyfin.Server.Implementations.Tests/Item/ItemPersistenceDeleteItemTests.cs', which suggests a test-related or source-patch conflict during the dotnet build rather than an explicitly identified dependency incompatibility. Both baseline and candidate package recipes share the identical structure (dotnetCorePackages SDK 10.0, same override arguments), differing only in version and source hash. No availableDependencyAlternatives are listed, so no previously-sourced jellyfin pin target is ready for selection. The root cause — whether jellyfin 12.1 itself has broken tests, a .NET 10 toolchain regresssion, or a nuget-deps mismatch — remains unconfirmed.

Rationale: No remediation can be safely proposed: the build error does not clearly identify an incompatibility that can be resolved by overriding a single dependency version, and zero availableDependencyAlternatives are provided for jellyfin, meaning there is no known-good previous derivation to pin to. A global override or blanket nixpkgs rollback would exceed the narrow leaf-application scope permitted by the advisory contract.

Classification: isolated-service-regression
Culprits: jellyfin
Model-reported confidence (not independently verified): 0.450
Controller note: The advisory worker selected diagnosis only.

Deterministic validation

No remediation was accepted; no branch or PR was created.

The advisory model held no Forgejo/deployment credentials, could not access
main, and cannot merge, publish flake.lock, or deploy. Human review remains
mandatory.
