Fix only the cases that are unambiguous anti-patterns; leave the
event-driven setState patterns (useNitroEvent / useMessageEvent
subscriptions, async fetches with cleanup) alone since they're
legitimate in this architecture.
- src/components/catalog/views/catalog-header/CatalogHeaderView.tsx:
displayImageUrl was pure-derived from imageUrl. Drop the useState +
useEffect entirely; compute in render.
- src/components/navigator/views/NavigatorRoomCreatorView.tsx:
the maxVisitors list (10..100 step 10) and roomModels/selectedModel
came from static config; convert to module-level MAX_VISITORS_LIST
constant + useState lazy initializers. Removes 2 init effects.
setCategory(categories[0].id) is left as-is because categories
arrives async from a hook.
- src/components/login/LoginView.tsx:
Replace useEffect(() => setLocalError(null), [step]) with the
React-recommended "track previous prop" render-time reset:
if(prevStep !== step) { setPrevStep(step); setLocalError(null); }
Same observable behavior, no extra render.
- src/components/room/widgets/choosers/ChooserWidgetView.tsx:
Wrap the selectItem callback prop call in useEffectEvent so a
parent re-render that changes selectItem identity doesn't
re-fire the visualizer side-effects.
Net: 4 fewer set-state-in-effect violations; behavior preserved.
The remaining ~328 violations across the codebase are predominantly
legitimate event-bus / async-fetch patterns and need per-case
review with running app, not a sweep.

Eliminate the four remaining missing-dependency warnings reported by
react-hooks v7. Each one was a real stale-closure or re-trigger hazard;
the fix matches the intent rather than just silencing the linter.
- src/App.tsx (line 448): wrap showSessionExpired with useEffectEvent
(onSessionExpired) so the prepare effect doesn't re-run on every
showSessionExpired identity change but still calls the latest
callback. Replace the two in-effect call sites.
- src/components/furni-editor/views/FurniEditorSearchView.tsx: wrap
the on-mount onSearch('', '', 1) call with useEffectEvent so the
callback prop isn't a missing dependency.
- src/components/notification-center/views/bubble-layouts/
NotificationBadgeReceivedBubbleView.tsx: wrap the
"fetch badges only if empty on mount" check with useEffectEvent
so badgeCodes.length isn't required as a dep (and won't re-fetch
every count change).
- src/components/navigator/views/room-settings/
NavigatorRoomSettingsRightsTabView.tsx: switch deps from
roomData?.roomId to roomData (the body uses roomData.roomId after
an early return; the linter wanted the whole object).
- src/api/ui-settings/UiSettingsContext.tsx: hoist ALL_CSS_VARS
outside the component (it's a static constant).
After this, yarn eslint reports zero exhaustive-deps warnings across
the whole src/.

Run eslint --fix across src/ to clear ~1900 mechanical lint errors
surfaced by the @typescript-eslint v8 + react-hooks v7 + react-compiler
upgrade in the React 19 modernization PR.
Issues fixed automatically:
- brace-style (Allman): try/catch one-liners reformatted to multi-line
- indent: tab-vs-space and depth corrections
- semi: missing trailing semicolons
- no-trailing-spaces
No semantic changes. Remaining 701 errors are real-code issues
(set-state-in-effect, rules-of-hooks, no-unsafe-* type checks) that
need manual per-file review.
