The v3 migration put application.Get() in backend/events and a ServiceStartup hook in backend/explore, both of which cmd/indexbuild reaches. v3's application package is GTK/WebKit bindings on Linux, so the index-artifact job — a plain golang container with CGO_ENABLED=0, on the stated grounds that neither command imports the app — stopped compiling with "undefined: pointer". That job owns the ~205 GB dump checkpoint, so it is the worst place to learn this. Both are behind the indexbuild tag now: the one app.Event.Emit lives in runtime_wails.go, runtime_indexbuild.go answers ErrNoRuntime (what the app itself returns before Run, so Deliver's callers need no second path), and explore's ServiceStartup moves to its own tagged file. TestIndexToolsDoNotImportWails walks `go list -deps -tags indexbuild` so the claim the workflow makes is checked rather than assumed.
