ImpactEngine

ImpactReport report = new ImpactEngine().ComputeImpact(workspace, entryId);

The service reads one stable entry and emits ChangedSource, StaleTranslation, VoiceReRecord, SubtitleReview and VisualRecheck items. Translation items are emitted for missing, stale or absent approvals. Voice items require a stale or missing take. Subtitle items compare the cue’s bound source hash. Visual items match a finding entry ID or a fixture ID equal to SceneOrFixture without case sensitivity.

ComputeImpact throws ArgumentNullException for a null workspace. It returns a report even when the entry has no current source revision.

Recompute after RevisionTracker processes a source edit. The engine reports current workspace state; it does not mutate or cache it.

The engine does not evaluate voice duration, provider assets or review states other than missing and stale.
