## 1. Implementation
- [x] 1.1 Add OpenSpec deltas for local image provider discovery, routing, and generation.
- [x] 1.2 Add no-auth provider support and local image provider settings template.
- [x] 1.3 Allow runtime model discovery to call local `/v1/models` without an API key.
- [x] 1.4 Ensure local image models infer generic OpenAI-compatible image bindings.
- [x] 1.5 Pass local image parameters through the generic image adapter.
- [x] 1.6 Add targeted tests for empty-key discovery, no-auth transport, local template defaults, routing, and image request payload.
- [x] 1.7 Add Model Center image model assets with official links, license/runtime metadata, import/install state, and `/v1/models` live status.
- [x] 1.8 Add a Model Center action that applies an installed local image model to the active image generation route.

## 2. Validation
- [x] 2.1 Run focused Vitest coverage for settings, discovery, routing, transport, and media executor.
- [x] 2.2 Validate local runtime script and frontend type/build checks; record existing Sass build blocker.
