Resilient Password Reset Notification Service

Problem/Feature Description

A SaaS platform's password reset flow uses the pidge notification library to deliver reset-link emails. The infrastructure team has reported that during peak traffic periods, some notifications fail due to momentary network hiccups between the application and the pidge API — these are short-lived and typically succeed on a second or third attempt. However, other failures (like emails sent to deactivated or malformed addresses) are permanent and wasting retries only delays the response to the user.

The team needs a robust send_password_reset async function that wraps the pidge dispatch call with smart retry behaviour: retrying on transient failures while giving up immediately on permanent ones. The function should be production-ready — logging what happened at each stage and making the outcome clear to the caller.

The pidge library (pip install pidge) is already available. The PIDGE_API_KEY environment variable will be set at runtime.

Output Specification

Produce a Python file password_reset_notify.py containing:

1. An async function send_password_reset(email: str, reset_url: str) -> dict that:

   • Dispatches a password reset notification to the given email address
   • Implements retry logic for transient failures
   • Returns a dict with outcome information for the caller

2. A brief if __name__ == "__main__": block that demonstrates calling the function with a sample email and URL (using asyncio.run).

Include all imports and make the file self-contained.
