# Cancelled Takedown Count

> Counts transitions into the CANCELLED status from the TakedownEvent log within the configured lookback window. Cancellations should be rare (typically 0-2 per week); a higher count usually signals a quality problem in the proposal funnel or a misuse of the CANCELLED status.

## Overview

Counts transitions into the `CANCELLED` status from the takedown event log within the
configured lookback window. Cancellations should be rare — typically zero to two per
week — so a higher count usually signals a quality problem in the proposal funnel or a
misuse of the `CANCELLED` status.
