Overview ¶
Package why wraps the internal run-level causal explainer (data-plane-memory A3) for use by the REST controller. It mirrors the thin service pattern used by the lineage and run services: a context + a run.Store, with a WithDatabase override for tests.

func (*Service) Why ¶
func (s *Service) Why(runID uuid.UUID, taskRef string) (*runstorage.WhyExplanation, error)
Why returns the causal explanation for taskRef (a task UUID or name) in run runID. A fanned step is answered as a group summary; use WhyPartition to select one instance.
func (*Service) WhyPartition ¶
func (s *Service) WhyPartition(runID uuid.UUID, taskRef, partition string) (*runstorage.WhyExplanation, error)
WhyPartition returns the causal explanation for ONE fan-out instance of taskRef, selected by its partition value. An empty partition is identical to Why. runstorage.ErrPartitionNotFound (whose message lists the available values) when the group holds no such partition.
