# Phase 34 Plan 05: German Translations Summary

German locale complete — all 6 namespaces translated with natural German using formal Sie form, registered in i18n config, and verified via automated key parity test.

## Tasks Completed

| # | Task | Commit | Files |
|---|------|--------|-------|
| 1 | Create German translation files for all namespaces | pre-existing (34-04 wave) | src/client/locales/de/*.json |
| 2 | Register German locale in i18n configuration | pre-existing (34-04 wave) | src/client/lib/i18n.ts |
| 3 | Write key parity test + fix collection gap | 31297a3 | src/client/locales/de/collection.json, tests/i18n/locales.test.ts |

## Verification Results

- All 6 de/*.json files: valid JSON
- `bun test tests/i18n/locales.test.ts`: 22 pass, 0 fail
- `bun run build`: success (914ms)
- i18n.ts: 6 German imports + de resource block + supportedLngs: ["en", "de"]

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Fixed missing German keys in collection namespace**
- **Found during:** Task 3 (key parity test)
- **Issue:** `de/collection.json` was missing 4 keys present in `en/collection.json`: `form.msrp`, `form.purchasePrice`, `form.itemNamePlaceholder`, `form.optionalNotes`
- **Fix:** Added the 4 missing German translation keys to `src/client/locales/de/collection.json`
- **Files modified:** src/client/locales/de/collection.json
- **Commit:** 31297a3

### Pre-existing Work

Tasks 1 and 2 were already complete from prior wave executions (plans 34-01 through 34-04). The German locale files and i18n.ts configuration existed on the branch before this plan executed. This plan's contribution was the gap fix and verifying the test passes.

## Known Stubs

None — all German locale values are substantive translations.

## Threat Flags

None — locale JSON files are static bundled assets with no runtime injection vector.
