#
# execute-work-order.sh — Execute a work order on sv-frontend
#
# Usage (from sv-payload):
#   ./scripts/execute-work-order.sh <work-order-file> [frontend-repo]
#
# Examples:
#   ./scripts/execute-work-order.sh work-orders/2026-02-15-add-stats-block.md
#   ./scripts/execute-work-order.sh work-orders/2026-02-15-add-stats-block.md frontend.porwoll.de
#
# This script:
# 1. Reads the work order
# 2. SSHs to sv-frontend
# 3. Updates payload-contracts dependency
# 4. Launches Claude Code with the work order as prompt (or prints instructions)
#
# Prerequisites:
# - SSH access to sv-frontend configured (~/.ssh/config)
# - Work order committed and pushed to payload-contracts main branch
