    - Integrates model enhancement configuration via `settings.models.footer` and `settings.models.provider-card` (targeted at `llm-pi-ai`).
    - Supports models.dev auto-fill matching, prefilling missing capacities, image modalities (`input: ["text", "image"]`), and multi-level reasoning efforts (`minimal` / `low` / `medium` / `high` / `xhigh` / `max`).
    - Uses `ctx.remote.settings.mutate` with revision fence checking for safe, non-destructive configuration persistence.
-   - Preserves official file attachment and upload pipeline (`ui-attachment` & `file-upload`), removing obsolete custom upload endpoint routes.

+   - Delegates session-level model and reasoning selection completely to official DSH 0.1.5-rc.2 core components.
 
-2. **Codex-style Model & Reasoning Effort Selector**:
-   - Injected into `conversation.input.right` seamlessly alongside the official composer.
-   - Reuses `ctx.modelDirectories` (`ModelDirectoryResolver`) for per-session directory resolution and selection dispatch.
-   - Interactive sliding track for reasoning effort adjustments and grouped model picker popup.

-3. **models.dev Cache & Proxy**:
+2. **models.dev Cache & Proxy**:
    - Exposes exact WebServer proxy route `/api/models-dev/models` with in-memory caching and fallback.

    - Dynamic localization supporting Simplified Chinese (`zh`) and English (`en`).
