**5 issues found** across 8 files Confidence score: **2/5** - There are multiple high-confidence, user-impacting risks in teardown and temp directory handling, so merge risk is elevated rather than minimal. - Most severe: in `desktop/src/dirs.rs`, using `create_dir_all` for `TempDir` can adopt an existing directory and delete it on drop; switching to `create_dir` avoids that destructive behavior. - `desktop/src/cef/context/multithreaded.rs` and `desktop/src/dirs.rs` still have panic paths (`unwrap()` in `Drop`, panic on temp cleanup read failure) that can crash shutdown/startup flows instead of failing gracefully. - Pay close attention to `desktop/src/dirs.rs`, `desktop/src/cef/context/multithreaded.rs`, `desktop/src/persist.rs`, `desktop/src/cef/context/singlethreaded.rs` - teardown/cleanup paths can panic, skip cleanup, or leave stale cache/temp data.

```text Check if these issues are valid — if so, understand the root cause of each and fix them. If appropriate, use sub-agents to investigate and fix each issue separately. P2: Avoid panicking on temp cleanup read failures; log and return so startup can continue. P1: Use `create_dir` (not `create_dir_all`) so `TempDir` creation fails when the target path already exists; otherwise a pre-existing directory can be adopted and then deleted on drop. P2: The old CEF cache cleanup is gated behind successful state loading, so it is skipped on common early-return paths (missing/corrupt state file). Move this cleanup outside the success-only path so stale cache data is consistently removed. P2: Temp directory cleanup is now single-shot; if CEF still holds file handles during shutdown, cache directories can be left behind. P1: Avoid `unwrap()` in `Drop`; a channel disconnect here can panic during teardown. ```
