✅ Done! Done — reviewed all six and posted my verdict on each: • #18023 (unknown URLs → in-app not-found) — ✅ Approved. Catch-all route inside the root layout is the right fix and also kills the React #418 hydration error. • #18024 (Manage backends → redirect off detail pages) — ✅ Approved. Good refactor into `useBackendSwitchRedirect`; left a non-blocking DRY note that

backend-selector.tsx

could share the same hook. • #18025 (single, accurate install/update errors) — 💬 Commented. Behavior and tests look solid; flagged one thing to confirm before merge —

now prefers

over

detail

composedPath()

is the correct root-cause fix, with a good

regression test and Playwright guard. • #18027 (Model Router / Agent Context in command menu; Ctrl+K off Apple) — ✅ Approved. The nav-invariant test is the standout. Left a cosmetic nit that the

class renders

Ctrl+K

as

. • #18028 (conversation header menu clamp + Escape) — ✅ Approved. Clamp, Escape-close-with-focus-return, and class scoping are all correct. CI is green on all six (the only "failure" is an old, superseded
