Maybe add a comment in the Supervision Controller here:

@DeleteMapping(value = "/studies/{studyUuid}/invalidate")
@Operation(summary = "Invalidate built nodes and delete root node network")

suggestion:

@DeleteMapping(value = "/studies/{studyUuid}/invalidate")
@Operation(summary = "Invalidate all node tree, clean stashed elements and delete root networks")

- Line 406: Update invalidateStudy around
networkModificationTreeService.deleteAllStashedElements(studyUuid) to catch and
handle cleanup failures separately, allowing processing to continue to
getStudyRootNetworkIds(studyUuid). Preserve the existing per-root try/catch
invalidation handling so failures for one root remain isolated.
