Template
Convert this callback-based code to async/await: {callback_code}. Step 1: Map the asynchronous flow: which operations are sequential, which are parallel, and which are conditional; draw the dependency order explicitly. Step 2: Identify error handling in the callback version, including errors currently swallowed or double-handled, and note any callback invoked more than once or never. Step 3: Convert to async/await, preserving the parallelism found in step 1 (using Promise.all or equivalent) rather than accidentally serializing. Step 4: Restructure error handling with try/catch scoped to match the original recovery semantics. Step 5: Compare old and new behavior for every path: success, each failure, and timeout, confirming equivalence.
