# Compare deployed container versions against local git HEAD
# Warns if containers are stale (built from an older commit)
#
# Usage:
# ./scripts/build-check.sh
#
# What it shows:
# - Local git HEAD commit SHA
# - Each container's built commit SHA (from Docker labels)
# - Whether containers are up-to-date or stale
# - Warnings if labels are missing (pre-07-02 containers)
#
# Label fields read:
# - org.opencontainers.image.revision = Git commit SHA embedded by deploy.sh
# - org.opencontainers.image.created = Build timestamp (ISO 8601 format)
#
# Exit codes:
# 0 = All containers up to date
# 1+ = Warnings or stale containers detected
#
# See: /docs/DEPLOYMENT.md for troubleshooting
