Suggestion: Storing the debounce timer on window introduces shared mutable state outside the component lifecycle; if the component unmounts/remounts, the pending timeout can still fire and update stale state, and multiple instances would cancel each other’s timers. Keep the timer in a component-scoped ref and clear it during unmount cleanup. [incorrect variable usage]
Severity Level: Major ⚠️
❌ Debris search triggers state updates after component unmount.
⚠️ Global window timer leaks across Debris lifecycle boundaries.Steps of Reproduction ✅
1. Run the app so `App` in `frontend/src/App.tsx` (lines 27-75) mounts the router, then
navigate to `/dashboard/debris`, which renders the `Debris` page component defined in
`frontend/src/pages/Debris.tsx` at line 40.
2. On the Debris page, type into the search input wired to `onSearch`
(`frontend/src/pages/Debris.tsx` lines 120-125), causing `onSearch` (lines 47-54) to
execute: it sets `searchQuery` and installs a debounce timeout on
`window._debrisSearchTimer` via `setTimeout` (lines 49-53).
3. Before the 400ms debounce delay elapses, navigate to another dashboard route such as
`/dashboard/satellites` handled by `<Route path="satellites" element<Satellites /> />` in
`frontend/src/App.tsx` line 52, which unmounts the `Debris` component and its hooks from
the React tree.
4. After the 400ms delay, the global timeout stored on `window._debrisSearchTimer` still
fires and invokes `setDebounced` and `setPage` (Debris.tsx lines 51-52) on the
now-unmounted component, causing React state updates on an unmounted component (a known
React anti-pattern) and leaving a shared global timer on `window` that is not tied to any
specific `Debris` instance.

Do not remove useTriggerAgent while keeping the trigger button.
The remaining “TRIGGER AGENT” button at Lines 343-348 now executes a no-op handler, so users cannot trigger an agent run. Restore and invoke the hook, or remove the button and its manual-trigger messaging.

clearTerminal function sets a timestamp on window._clearedAt but nothing in the component reads that value to filter allDecisions. The terminal display will never actually clear when the button is clicked — this looks like an incomplete implementation where the filtering step was forgotten. Consider using a useRef to track the cleared-at time and filtering allDecisions against it, or simply exposing a local state variable to drive the display.

clearTerminal uses window as any while Debris.tsx in the same PR properly narrows via window as unknown as { ... }. Keeping any here is inconsistent and bypasses type safety for all other properties on window.

Safe to merge — these are targeted lint/type cleanup changes with no logic rewrites and no API surface modifications.
The
clearTerminalfunction in AIAgents.tsx sets a timestamp onwindowbut nothing in the component reads it, so clicking "Clear Terminal" has no visible effect on the UI. This is a pre-existing bug surfaced here because the surrounding code was touched during cleanup, and the suppression comment draws attention to it without actually fixing it.frontend/src/pages/AIAgents.tsx — the
clearTerminalfunction is a no-op and warrants a closer look before merging if the Clear Terminal button is user-facing.Important Files Changed
