 ### Migration log
 
+- `ShareNext` — migrated 2026-04-11. Swapped remaining async callers to `AppRuntime.runPromise(ShareNext.Service.use(...))`, removed the `makeRuntime(...)` facade, and kept instance bootstrap on the shared app runtime.
 - `Storage` — migrated 2026-04-10. One production caller (`Session.diff`) and all storage.test.ts tests converted to effectful style. Facades and `makeRuntime` removed.
