Post Tail Alerts to N1netails

In the context of N1netails, a tail alert refers to a lightweight, structured notification triggered by a client system (such as a service, application, or script) to report an event, issue, or anomaly. These alerts are designed to be easy to emit, fast to process, and rich in metadata — making them ideal for real-time monitoring, embedded systems, or edge environments.

🦊 Why “Tail”?

The term "tail" in n1netails plays on two ideas:

1. Log tailing – Observing the last lines of logs (like tail -f) to detect anomalies in real-time.
2. Fox tails (kitsune/ninetails) – Thematically tied to the project’s branding, each "tail" represents a meaningful signal from your system.

A tail alert is essentially your system saying:

"Something noteworthy just happened — here's what it is, and here’s the relevant context."
