// content/non-content boundary the content-gatekeeper hook uses. These tests
// pin that boundary so the gate fires on the short-form draft paths the five
// creation commands (post/quick/react/carousel/video) actually write to, and
// stays silent on plugin infrastructure (commands, hooks, references, config).
