# HAC-26 Workspace State Foundation
Date: 2026-03-31 UTC
Owner: Senior Frontend Engineer
Issue: HAC-26
Scope: `apps/desktop` frontend foundation only
## Context
- `apps/desktop/src/App.tsx` already owns the visible desktop-v1 shell, but it still contains repeated inline logic for key filtering, selected-key fallback, live key replacement, and paged append handling.
- These state transitions are part of the browsing and inspector foundation, not one-off UI copy, and upcoming desktop-v1 slices will need them again.
- The PM comment on `HAC-26` asked for the highest reusable foundation return, not a new visible feature.
## Decision
- Do not expand product scope.
- Extract reusable key-workspace state helpers from `App.tsx` into `src/lib`.
- Cover the extracted state transitions with focused Vitest cases so future desktop-v1 changes can reuse the same behavior safely.
## Planned Implementation
1. Create a shared frontend utility for:
- filtering visible keys by search text
- resolving selected key fallback when visible results change
- replacing a key record after live metadata/value refresh
- appending paged browse results without duplicate rows
2. Update `App.tsx` to consume the shared utility instead of inline logic.
3. Add Vitest coverage for zero-result fallback, selection resolution, replacement merge behavior, and append deduplication.
4. Re-run `pnpm --filter @redis-gui/desktop test` and `pnpm run desktop:build`.
## Acceptance
- `App.tsx` no longer owns the reusable key-workspace list and selection transitions inline.
- The extracted helper is covered by focused tests.
- Existing desktop frontend tests and production build remain green.
- No backend contract or visible feature scope changes are introduced.
