/**
* A tracked finding extends the {@link DetachedFinding} by additional
* attributes that are calculated via tracking. The class is intended to be
* immutable, especially regarding the ID attribute. The
* {@link #setDeathCommit(CommitDescriptor)} method is exposed due to historical
* reasons, but is expected to be called only once in the lifecycle of a tracked
* finding.
*
* This class is used for communication with IDE clients (via the
* {@link org.conqat.engine.service.shared.client.IdeServiceClient}), so special
* care has to be taken when changing its signature.
