Artifact Frontmatter

Emits the skimmable two-layer skim block at the TOP of every phase artifact — TL;DR, phase + complexity tier, what-changed-since-last-version, decisions locked (and which flipped from a Recommended default), open [VERIFY WITH PM] items, and a one-line reading guide. Goal — a reader answers what / phase / what-changed / what's-open in under 60 seconds without reading the body. Composable; phase agents invoke it as their first output step.
