Rename or duplicate a level and three kinds of reference in your cinematics go dead together: possessable bindings, Event Track key payloads and Dynamic Binding resolver payloads. Each stores an absolute path into the level the sequence was authored against.
The engine repairs one of them. FixActorReferences needs the sequence open in Sequencer, has no headless path, and does not touch Event Track payloads at all, so those get fixed keyframe by keyframe in every shot.
This plugin walks the whole tree and opens nothing. Point it at a folder and it recurses every subsequence and shot, repairs what it can prove, and writes a row per sequence. On the demo cinematic (one master, four reels, forty two shots) that is 47 sequences, 129 binding sites and 63 event payload sites in 2.7 seconds, with no Sequencer instance.
A payload lives in the director blueprint’s compiled entry point, so every repair is recompiled and read back out of the bytecode. If the old path is still there the write is rolled back. On that run every payload repair passed the read back.
It refuses rather than guesses. A reference is repaired only when the level moved, the actor moved, or exactly one actor carries the label. Everything else is listed with every candidate it considered. That run refused four references from three causes: an ambiguous label, a wrong class stand in, and two references to a deleted actor.
Every run writes a JSON journal and prints the exact Undo command. The commandlet returns documented exit codes (0 Clean, 2 Repairable, 3 NeedsReview) and never returns 1, so a build server cannot mistake an engine failure for a verdict.
