Please address the comments from this code review:

## Overall Comments
- In `reconcilePublishStatus`, repeated failures to fetch `/release/zenodo/status` are silently ignored; consider logging or surfacing a more explicit error state so unexpected backend issues don’t leave the UI stuck in the generic `pending` state.
- The fixed timeout values `ZENODO_API_TIMEOUT_MS` and `ZENODO_UPLOAD_TIMEOUT_MS` are hard-coded; consider making them configurable via environment variables so they can be tuned for different deployment environments or unusually large releases.

**suggestion:** Consider handling fetch timeouts explicitly so users see a clearer error than a generic AbortError message.

`AbortSignal.timeout` prevents hanging, but when it fires `fetch` rejects with an `AbortError` whose message (e.g. "The operation was aborted") is not very helpful. Since `failPublication` displays `err.message`, users will see a vague error. Consider catching `AbortError` around these long-running requests (or in a shared wrapper) and rethrowing a clearer message like "Zenodo upload timed out after 5 minutes; please retry" so timeouts are distinguishable from other failures.

Suggested implementation:

```typescript

/**
    body: body.toString(),
=======
 // Request timeouts so a stalled network call can never hang the publication
 // workflow indefinitely. Metadata/API calls are quick; file up/downloads and
 // the repo zipball can be large, so they get a much longer budget.
 const ZENODO_API_TIMEOUT_MS = 60_000; // metadata / publish / deposition / API calls
 const ZENODO_UPLOAD_TIMEOUT_MS = 300_000; // file up/downloads & repo zipball

 // ===== Error helper ==================================================

 /**
     body: body.toString(),
+
+/**
+ * Normalize errors from Zenodo calls so we can surface clearer messages to the user.
+ *
+ * In particular, when AbortSignal-based timeouts fire, fetch rejects with an AbortError
+ * whose default message ("The operation was aborted") is not helpful. Callers should
+ * pass the timeout and a short context string (e.g. "file upload") so we can generate
+ * a clearer message.
+ */
+export function normalizeZenodoError(
+  err: unknown,
+  timeoutMs?: number,
+  context?: string,
+): Error {
+  if (err instanceof Error && err.name === "AbortError" && timeoutMs && context) {
+    const minutes = Math.round(timeoutMs / 60_000);
+    return new Error(
+      `Zenodo ${context} timed out after ${minutes} minute${minutes === 1 ? "" : "s"}; please retry.`,
+    );
+  }
+
+  return err instanceof Error ? err : new Error("Zenodo request failed");
+}

```

To fully implement the suggestion, you should also:

1. **Wrap long-running fetches in try/catch and use `normalizeZenodoError`**. For example, where you perform metadata/API calls:
   - Locate the `fetch` that uses `signal: AbortSignal.timeout(ZENODO_API_TIMEOUT_MS)` (the one that produces `res` just above the `if (!res.ok)` block).
   - Wrap it as:
   ```ts
   let res: Response;
   try {
     res = await fetch(url, {
       // ...existing options...
       signal: AbortSignal.timeout(ZENODO_API_TIMEOUT_MS),
     });
   } catch (err) {
     throw normalizeZenodoError(err, ZENODO_API_TIMEOUT_MS, "API request");
   }
   ```
2. **Do the same for file uploads/downloads** using `ZENODO_UPLOAD_TIMEOUT_MS`:
   ```ts
   let res: Response;
   try {
     res = await fetch(uploadUrl, {
       // ...existing options...
       signal: AbortSignal.timeout(ZENODO_UPLOAD_TIMEOUT_MS),
     });
   } catch (err) {
     throw normalizeZenodoError(err, ZENODO_UPLOAD_TIMEOUT_MS, "file upload");
   }
   ```
3. **Ensure `failPublication` (or any shared error handler) still displays `err.message`**, but now the error has already been normalized by `normalizeZenodoError`, so users will see the clearer timeout-specific message instead of the generic `"The operation was aborted"`.

You may need to adjust import paths if `normalizeZenodoError` is moved to or used from other modules in your codebase.
