# Asynchronous Task Executor with Type Annotations

This Python coding drill benchmarks the performance of an asynchronous task executor that uses type hints for improved readability, maintainability, and code robustness.

## Problem Description

Create a module `async_task_manager.py` which should implement two functions:

1. `execute_tasks`: Accepts an iterable of coroutine functions and runs them concurrently using asyncio.
2. `delayed_task(n: int) -> float`: Simulates work with delays provided by the argument `n`.

The module must be fully typed, including handling generic types.

## Instructions

- Do not install any external libraries; rely only on Python's standard library.
- Ensure your code passes all provided self-tests and prints proper metrics before concluding with 'VERIFIED' if successful or 'RESULT: <error>' otherwise.

--- AUTO FIX ---
Replaced invalid benchmark script with deterministic ARES recovery benchmark.
