name: Changelog armed
description: >-
  Assert the changelog is armed for the tree's version state — the
  version-keyed guard (box#108, rig#66; the unconditional form was reverted
  by rig#44 and cast#108). The caller must have checked out its own
  repository first: the guard reads the consumer's tree at the workspace.

  version-source:
    description: Where the tree's version lives ("file" or "package-json")

    default: file
  changelog:

    required: false
    default: CHANGELOG.md
