# Greeting Check-in The heir's pull-based health check. Replaces the deleted weekly auto-update workflow. Fires from [greeting-checkin.instructions.md](../../instructions/greeting-checkin.instructions.md) on the first greeting of a session, or on demand via `/checkin`. ## Greeting Recogniser Match case-insensitively against the trimmed first message.

Check Edition version Run the upgrade script in dry-run mode and capture stdout: ```bas
