• #14490 75d8cb0 Thanks @petebacondarwin! - Fix edge cases on the local R2 public bucket endpoint (/cdn-cgi/local/r2/public) to match r2.dev: write methods are rejected with 401, malformed/multiple/inverted ranges with 400 and unsatisfiable ranges (including bytes=-0) with 416, Range is honored on HEAD requests with a bodyless 206, Content-Range is correct for suffix ranges, object keys are percent-decoded exactly once (keys containing a literal % no longer fail), and objects stored without a content type are served as application/octet-stream instead of omitting the Content-Type header. Unread object bodies are also cancelled (on HEAD and unsatisfiable-range responses) instead of leaking a read stream until garbage collection.

• #14490 75d8cb0 Thanks @petebacondarwin! - Add Workflow introspection to createTestHarness()

  Worker handles can now introspect Workflow bindings by name, allowing tests to disable sleeps, mock step results, and wait for Workflow outcomes. Tests can introspect a known Workflow instance by ID or track instances created after introspection starts.

  const harness = createTestHarness({
  	workers: [{ configPath: "./wrangler.json" }],
  });
  
  const worker = harness.getWorker();
  await using workflow = await worker.introspectWorkflow("MY_WORKFLOW");
  
  await workflow.modifyAll((modifier) =>
  	modifier.disableSleeps([{ name: "wait-for-approval" }])
  );
  
  const response = await worker.fetch("/start-workflow");
  const [instance] = await workflow.get();
  await instance.waitForStatus("complete");
