# Install the supervisor worker that runs AI voice-analysis jobs.
#
# Why a separate worker: transcription of a long call takes minutes, while the
# existing ccsystem worker runs with --timeout=120 and would kill the job
# mid-flight. This program listens on the `ai` queue only, with a much longer
# timeout.
#
# Run it on the application server as root:
#
#     bash deploy/ai-voice-queue-worker.sh
#
# It is idempotent: running it again rewrites the same file and restarts the
# program. It never touches the existing /etc/supervisor/conf.d/laravel-queue.conf.

Done. Useful checks:

  supervisorctl status | grep ccsystem-ai-queue           # RUNNING? (the process is ccsystem-ai-queue:ccsystem-ai-queue_00)
  tail -f /var/log/ccsystem-ai-queue.log                  # job output
  sudo -u www-data env HOME=/tmp php /var/www/ccsystem/artisan queue:monitor ai

Pending analyses are rows in call_ai_analyses with status = 'queued'; they are
picked up by this worker within a few seconds.
