# validate-compose.sh — gate `docker-compose.yml` /
# `compose.yaml` files against the upstream Compose spec.
#
# Docker's compose loader is permissive (it accepts deprecated
# v2 / v3 syntax that newer engines reject silently). A
# pre-merge gate using noyavalidate against the Compose
# JSON Schema catches drift before it hits `docker compose up`.
#
# Usage (from repo root):
#   crates/noya-cli/examples/validate-compose.sh
#   crates/noya-cli/examples/validate-compose.sh path/to/dir
#   crates/noya-cli/examples/validate-compose.sh path/to/file.yaml
