Severity: Medium — found during a deep project review (2026-07-06). A full en/de key-parity diff across all 14 namespaces found only these mismatches (everything else has exact parity, and namespace registration in client/src/i18n/index.ts is clean).
Findings
photoAnnotator: 5 keys missing in de — client/src/i18n/de/photoAnnotator.json lacks reset, resetTitle, resetBody, resetConfirm, resetComplete (present in en). Note: no code references these keys (PhotoAnnotator.tsx/ToolPalette.tsx have no reset usage) — they are also orphaned in en. Either wire them up + translate, or remove from en.budget: 2 dead de-only keys — client/src/i18n/de/budget.json has overview.costBreakdown.autoOriginBadge.label and .ariaLabel absent from en; no code references them. Remove from de.usePhotos hardcodes English error strings, bypassing translateApiError — client/src/hooks/usePhotos.ts:55-59 sets 'Failed to load photos.', 'Network error: Unable to connect to the server.', 'An unexpected error occurred.' directly into UI state. Route through translateApiError() / translated keys.
Suggested guard
Add a key-parity unit test (compare key sets of every en/de namespace pair) so parity breaks fail CI instead of accumulating.
