Rudra-narayan-muduli-001/Python-Event_Bus ? reverse-engineered prompt

Build me a simple Python event bus library for an AI agent, something I can use to publish events and let different parts of the app react to them without being tightly coupled.

I want it to support both sync and async handlers, a nice decorator for subscribing to events, and a clean way to emit events with payloads. Please include priority based dispatching, filtering by things like event name or category, and a middleware pipeline for things like logging, rate limiting, deduping, metrics, and context propagation. It should also keep track of correlation and causation IDs, validate events against a known registry, and store events so they can be queried and replayed later. If it makes sense, add basic dependency injection support, a config loader, and tamper evident audit logging. Make it thread safe and usable from a small example app. Look up current docs online if you need to, but keep the code simple and practical.
