# Phase 34 Plan 02: Extract Hardcoded UI Strings Summary

All hardcoded English strings in UI components replaced with react-i18next `t()` calls, with full English and German locale coverage added for all new keys.

## Tasks Completed

| Task | Description | Commit |
|------|-------------|--------|
| 1 | Audit hardcoded strings across all components | (analysis only) |
| 2 | i18n collection and item components | c5af124 |
| 3 | Extract strings from thread/candidate components | 6fd8874 |
| 4 | Extract strings from modals, routes, and catalog | 2aa156a |
| 5 | Onboarding and settings (already i18n — no changes needed) | — |

## Scope

Components updated in Task 2-3 (from prior session):
- CandidateCard, CandidateListItem, CandidateForm, ComparisonTable, StatusBadge
- CreateThreadModal, AddToThreadModal
- SetupsView, SetupCard, ShareModal

Components updated in Task 4 (this session):
- AddToCollectionModal
- routes/collection/index.tsx (tab labels)
- routes/threads/$threadId/index.tsx (thread detail + AddCandidateModal)
- routes/items/$itemId.tsx (item detail page)
- routes/setups/$setupId.tsx (setup detail page)
- routes/users/$userId.tsx (public profile page)
- routes/global-items/index.tsx (catalog/discover page)

## Locale Files Extended

### English
- `collection.json`: added `addToCollection`, `item` sections
- `threads.json`: added `candidateForm.priceLabel`, `detail` section
- `setups.json`: added `namePlaceholder`, `creating`, `emptyState`, `detail`, `profile` sections
- `common.json`: added `actions.duplicate`
- `catalog.json`: created new namespace for global-items page

### German (parity with English)
- `collection.json`: added all missing sections to reach parity with English
- `threads.json`: added all missing sections (card, candidateCard, candidateForm, comparisonTable, addToThread, statusBadge, planning, detail)
- `setups.json`: added namePlaceholder, creating, emptyState, detail, profile, impact.compareWith
- `common.json`: added actions.duplicate, home, imageUpload, profile sections
- `catalog.json`: created new namespace with German translations

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 2 - Missing functionality] Created catalog.json namespace**
- **Found during:** Task 4 (global-items route)
- **Issue:** No dedicated namespace existed for the catalog/discover page strings
- **Fix:** Created `src/client/locales/en/catalog.json` and `src/client/locales/de/catalog.json`, registered in i18n.ts
- **Files modified:** `src/client/lib/i18n.ts`, both catalog.json files
- **Commit:** 2aa156a

**2. [Rule 2 - Missing functionality] German locale parity**
- **Found during:** Task 4 completion
- **Issue:** German locale files were missing large sections added to English in this plan
- **Fix:** Added all missing German translations for collection, threads, setups, common namespaces
- **Files modified:** de/collection.json, de/threads.json, de/setups.json, de/common.json
- **Commit:** 2aa156a

### Skipped Items
- Task 5 (onboarding + settings): All 5 onboarding components and settings.tsx were already fully i18n-wired with `useTranslation`. Only language option labels (`"English"`, `"Deutsch"`) remain as literals — these are native language names conventionally left untranslated.

## Known Stubs

None — all t() calls reference real locale keys that exist in both en and de files.

## Self-Check: PASSED
