Stored legacy aliases such as `zh-Hans` are normalized to canonical locale codes before the setting reaches React state. `date_display_format` is installation-local and controls rendered dates in note rows, property chips/cells, note info, table-of-contents metadata, and search result subtitles; date picker text input remains ISO for predictable manual entry and storage. `note_width_mode` is the installation-local default for rich-editor note width; individual notes can override it with `_width` when they already have frontmatter. `sidebar_type_pluralization_enabled` is installation-local and defaults to `true`; when false, type rows use exact type names unless the type document defines an explicit `sidebar_label` override. `default_ai_agent` remains the legacy installation-local CLI fallback. `default_ai_target` is the active AI target used by the AI panel and status bar; it can point at a coding agent or a configured direct model. `ai_model_providers` stores non-secret provider metadata for local/API model targets, while hosted API keys live in Tolaria's local app-data secrets file or user-managed environment variables instead of being persisted in app settings. Provider defaults and local/API grouping come from the shared `src/shared/aiModelProviderCatalog.json` catalog used by both renderer settings and the Tauri direct-model runtime. `hide_gitignored_files` is also installation-local and defaults to `true`; changing it reloads entries, search, saved views, and folders without restarting.

The AutoGit fields are also installation-local: `useAutoGit` consumes them to schedule automatic checkpoints, while `useCommitFlow` and the status bar quick action reuse the same checkpoint runner and deterministic automatic commit message generation.

 `App.tsx` derives the effective locale from settings and browser/system language hints, then passes it down to localized surfaces. Settings exposes a keyboard-accessible shadcn `Select`, and the command palette includes actions to open language settings or switch directly to a supported language.
