# upload_status.sh
# Uploads /tmp/<status-file>.json to remote nginx web server.
#
# Usage:  sh upload_status.sh [filename]
#   filename — optional, defaults to test-status.json
#
# Called from n8n Execute Command nodes after every status
# change (lock acquire/release, test start, test complete).
#
# SETUP (inside n8n Docker container — run once):
#   apk add sshpass openssh-client
#   echo 'YOUR_SFTP_PASSWORD' > /home/node/scripts/.ftp_pass
#   chmod 600 /home/node/scripts/.ftp_pass
#   chmod +x /home/node/scripts/upload_status.sh
#
# ALWAYS exits 0 — upload failures must never break n8n flow.
