Hi @Tomohiro_Hiratsuka, thanks for the follow-up — the restart numbers are very helpful. The fact that the count returns to roughly 9,800 files under backend/nestjs/src immediately after a restart suggests something that watches every TypeScript file in the project, rather than something that accumulates over a long session.
