DECLARATIVE-YAML-12: Run a YAML config from the CLI

What it demonstrates

Feeding a declarative config into the validate command, which auto-discovers markdown-contract.yaml or takes an explicit –config.

Builds on: DECLARATIVE-YAML-11: Route several globs first-match-wins, with named contracts and exclude

How it’s done

A terminal session: the command as you’d run it, followed by the output it prints; trailing comments note the exit status.

# auto-discovers markdown-contract.yaml in the working dir:
markdown-contract validate docs/planning

# or point at one explicitly, JSON findings, exit 1 on errors:
markdown-contract validate docs/planning --config markdown-contract.yaml --format json

Surfaces exercised

• CLI validate <path> --config --format
• loadConfigFile -> runCorpus
• exit 0 clean / 1 errors / 2 usage
