🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Restore globalThis.fetch after each test.

Line 244 and Line 282 replace the process-global fetch. The finally blocks restore only the spies. Later tests can receive the fake 200 response and become order-dependent.

Save and restore the original function in both tests.

Proposed fix 
   test.each(cases)("maps $label identically on regular and compact Responses", async testCase => {
+    const originalFetch = globalThis.fetch;
     let upstreamCalls = 0;
     globalThis.fetch = (async () => {
       upstreamCalls += 1;
       return jsonResponse(completedPayload("unexpected upstream response"));
     }) as typeof fetch;
@@
     } finally {
+      globalThis.fetch = originalFetch;
       errorLog.mockRestore();
       authSpy.mockRestore();
     }
   });

   test("unknown auth-resolution errors reject on both handlers instead of being mapped", async () => {
+    const originalFetch = globalThis.fetch;
     let upstreamCalls = 0;
     globalThis.fetch = (async () => {

the process-global fetch mock in both tests after each test completes. Save the
original globalThis.fetch before replacing it, then restore that exact function
in the existing finally blocks alongside the spies, including the test covering
