Ladder Summary

file This script is a small CLI tool that takes a repository name as an argument, locates that demo repository and its state directory, calls the **`renderLadder(repoDir, stateDir)`** function (imported from `../engine/ladderRender.js`) to materialize the repo’s ladder data stored in Git notes into a readable plain‑text representation, and writes that output (prefixed with a header showing statistics) to `state/<repo-name>/ladder.txt`. The file does not export any functions or classes itself—it only executes the described logic when run.

// Materializes a repo's Ladder (stored as git notes, not easy to browse

// directly) into one flat, readable text file. A dump for a human to look

// at, not a second source of truth; re-run any time after the real notes

// change, since this always reads live from the repo's own notes refs.
