 - Localized the Admin System runtime and CV benchmark diagnostics, including probe/email failures, model/Ollama state, parser findings, benchmark summaries, fallback guidance, and locale-aware timestamps while leaving runtime/provider/file values untouched.
 - Consolidated active list/dashboard/Kanban/reminder loading and failure presentation through the shared resource notice. Retry/progress accessibility follows EN/NB, duplicate fallback text is suppressed, and Kanban drag/keyboard announcements are localized.
 - Migrated Admin Audit to the shared retryable resource state so an unavailable API is no longer misreported as an empty log. Audit actions/dates, notification-setting feedback, profile-load fallbacks, and CV extraction run notifications now follow EN/NB while stored event/profile content remains unchanged.
+- Localized the pre-authentication security-check label and the embedded Turnstile challenge language, so switching to Bokmål no longer leaves the verification widget in English.

 - Post-fix complete regression: backend 716/716 and frontend 62 suites with 268/268 tests passed; the optimized Next production build and integrated TypeScript check passed.
 - Shared view-state focused verification: 3 suites and 15/15 tests passed, including Bokmål loading/retry and Kanban interaction coverage; TypeScript passed.
 - Admin Audit/settings/profile focused verification: 3 suites and 17/17 tests passed, including unavailable-versus-empty recovery and Bokmål audit actions that preserve stored event content; TypeScript passed.
+- Turnstile/auth recovery focused verification: 4 suites and 18/18 tests passed; the provider widget receives the Bokmål language code and TypeScript passed.

 - Full backend: 712/712 tests passed on .NET 9.
 - Next optimized production build and TypeScript: passed after the Job Workspace/checklist batch.
