You can simple use pop to retrieve the element and remove it from the array.

Suggested change

	const entryToPop = runDataArray[runDataArray.length - 1];
	// Preserve inputOverride so the LLM's input stays visible in logs after resume.
	const preservedInputOverride = entryToPop?.inputOverride;
	runDataArray.pop();
	const entryToPop = runDataArray.pop();
	// Preserve inputOverride so the LLM's input stays visible in logs after resume.
	const preservedInputOverride = entryToPop?.inputOverride;

Can runDataArray actually have undefined as an entry? If not then .pop() can not return undefined here doe to the outer check if (runDataArray?.length > 0) {, which is not recognized by TS apparently, so instead of optional checks like entryToPop?.inputOverride; you could also do const entryToPop = runDataArray.pop()!; (with !) which will ensure that this entry is not undefined also for TS (it will throw an error if it's undefined afaik).
