Add OpenRouter Fusion Flash model support

✨ Enhancement 🧪 Tests 🕐 Less than 10 minutes

AI Description

• Add Fusion Flash to the selectable OpenRouter model catalog.
• Verify requests preserve the documented openrouter/fusion-flash model identifier.

Diagram

  Picker["Model Picker"] --> Catalog["Model Catalog"] --> Adapter["OpenRouter Adapter"] --> Request["Chat Request"]
  Request --> API["OpenRouter API"]

High-Level Assessment

The current approach is optimal: register the model in the existing catalog and reuse the established OpenRouter-compatible adapter. A dedicated adapter would duplicate behavior without providing a meaningful benefit.

📝 Walkthrough

Walkthrough

The OpenRouter configuration now registers the openRouter_fusion_flash model. Thin-adapter tests use this model and verify that configured adapters send the expected model identifier.

Changes

OpenRouter Fusion Flash support

Layer / File(s)	Summary
Register Fusion Flash model `src/config/index.mjs`	The OpenRouter model key list includes `openRouter_fusion_flash`. Its metadata uses `openrouter/fusion-flash` and the description `OpenRouter (Fusion Flash)`.
Validate adapter model requests `tests/unit/services/apis/thin-adapters.test.mjs`	The OpenRouter fixture uses Fusion Flash. The shared adapter test verifies the request body model when an expected model is configured.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e5afe

This change adds one selectable OpenRouter model and verifies that its exact identifier is sent through the existing request path. No actionable merge-blocking risk remains after normal checks and review.

1. Preserve existing Fusion coverage 🐞 Bug ⚙ Maintainability

Description

The OpenRouter thin-adapter fixture replaces the existing openRouter_fusion case with
openRouter_fusion_flash, so the test suite no longer verifies that the already-supported Fusion
model resolves to and sends openrouter/fusion. Both models remain independently registered, making
this a coverage regression rather than a deliberate consolidation.

Code

tests/unit/services/apis/thin-adapters.test.mjs[71]
+    apiMode: { groupName: 'openRouterApiModelKeys', itemName: 'openRouter_fusion_flash' },

Evidence
The configuration retains two distinct OpenRouter model keys and values, while the changed test
array contains only the Flash key and expected ID. The new assertion validates only the model
selected by each fixture, so it cannot preserve coverage for the removed Fusion fixture.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The OpenRouter adapter fixture was changed from `openRouter_fusion` to `openRouter_fusion_flash`, which removes request-path coverage for the existing Fusion model.

## Issue Context
Both model keys remain independently registered in `src/config/index.mjs`, and the model assertion is conditional on each fixture's `expectedModel`. Preserve the original fixture and add a second OpenRouter fixture for Fusion Flash.

Pull request overview

Adds support for the openrouter/fusion-flash model in the OpenRouter API model picker and strengthens unit coverage to ensure the selected OpenRouter model ID is propagated into the /chat/completions request body.

Changes:

Added openRouter_fusion_flash to the openRouterApiModelKeys list and defined its Models entry as openrouter/fusion-flash.
Updated the OpenRouter thin-adapter unit test to select the new model and assert the outgoing request body includes the expected model value.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated no comments.

File	Description
tests/unit/services/apis/thin-adapters.test.mjs	Updates the OpenRouter adapter test case to use Fusion Flash and asserts the serialized request body contains the expected `model` ID.
src/config/index.mjs	Registers the new OpenRouter model key and maps it to the `openrouter/fusion-flash` model value for the picker/config system.

Reviewed changes

src/config/index.mjs: registered openRouter_fusion_flash in openRouterApiModelKeys and added its Models entry mapping to openrouter/fusion-flash — one row after the existing openRouter_fusion, matching the established naming and ordering conventions.
tests/unit/services/apis/thin-adapters.test.mjs: switched the openrouter-api thin-adapter fixture to openRouter_fusion_flash and added an expectedModel assertion that verifies the exact model ID reaches the /chat/completions request body; the assertion runs only when a fixture declares an expectation, so non-OpenRouter adapters are unaffected.

Mechanically sound: adding the key to the group array surfaces the entry in the OpenRouter picker (ModelGroups value + apiModes derived from Models), the config plumbing resolves openRouter_fusion_flash → openrouter/fusion-flash unchanged, and the new assertion pins exactly the behavior the PR claims. Full suite passes (1040/1040), and the ID matches OpenRouter's own fusion-router documentation.
