- OpenRouter app-attribution headers added for direct requests whose resolved origin is exactly
https://openrouter.ai(HTTP-Referer,X-OpenRouter-Title,X-OpenRouter-Categories), merged into request headers only. - New focused test file covering built-in OpenRouter, a custom provider pointing at the OpenRouter origin, and a third-party proxy endpoint.
Reviewed the full diff for both changed files. The header contract matches OpenRouter's official app attribution docs: HTTP-Referer (required, app's public URL/ranking id), X-OpenRouter-Title (display name), and X-OpenRouter-Categories (max 2 per request, lowercase hyphen-separated) — the chosen general-chat,writing-assistant value and casing are valid. The origin check runs against request.requestUrl at call time, which is the same URL passed straight to fetchSSE, so the gated origin and the actual fetch target cannot drift. The try/catch on new URL(requestUrl) correctly falls back to no headers for malformed/missing URLs. The three tests assert exact URLs, Authorization, and presence/absence of the attribution headers (plus a body-leak check), and they exercise the real fetch path via the same t.mock.method(globalThis, 'fetch', ...) pattern used elsewhere in the suite, so they would fail if the logic regressed.

Attribute direct OpenRouter API requests to ChatGPTBox so usage can appear in OpenRouter app rankings and analytics. Keep attribution headers off third-party proxy endpoints by checking the resolved request origin. Reference: https://openrouter.ai/docs/app-attribution

121-159: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd a negative test for an OpenRouter-like origin.
This test only checks an unrelated origin. A predicate based on a substring or hostname suffix would still pass it. Add a custom provider with
https://openrouter.ai.evil/v1and assert that attribution headers are absent. This verifies the exact-origin contract.🤖 Prompt for AI Agents
