- The Other nav entry is hidden while the feature is off
(nav-item--hidden, toggled client-side after enabling) and now uses the
fa-shapes icon.
- Shared utils/otherModels.js helpers (enable through the settings API,
open the settings Library section) are reused by the disabled page, the
announcement banner and the download modal.
- BannerService registers a one-time dismissible "other-models-announcement"
banner while the feature is off; SettingsManager drops the banner and
updates the nav when the master switch flips.
- A disabled download routing answer now surfaces a showActionToast with an
"Enable Other Models" action.
- Settings UI: master toggle + five sub_type checkboxes whose default-root
selects are disabled when unchecked; i18n keys added to en.json and synced
(other locales keep TODO placeholders).
The download modal's location step decided between checkpoint and unet
roots using only the CivitAI file-type signal, while the backend also
falls back to DIFFUSION_MODEL_BASE_MODELS. Models like Anima (file type
"Model") were offered checkpoint roots in the UI even though
use_default_paths would route them to the unet root.
- Extract the two-tier decision into py/services/download_routing.py and
reuse it in DownloadManager._execute_download
- Add POST /api/lm/download/routing so the UI asks the backend for the
routing decision; fall back to the local file-type check on failure
- ModelVersionsTab: search both checkpoint and unet roots when resolving
an existing version's download path
