 /**
  * Copy Addresses for Publishing
  *
- * This script copies the actual addresses.json files from horizon and subgraph-service
- * packages to replace the symlinks before npm publish.
- *
- * Why we need this:
- * - Development uses symlinks (committed to git) for convenience
- * - npm publish doesn't include symlinks in the published package
- * - We need actual files in the published package for consumers
- *
- * The postpublish script will restore the symlinks after publishing.
+ * Replaces the dev-time symlinks under src/<name>/addresses.json with real
+ * file copies before npm publish — npm does not include symlinks in the
+ * published tarball. restore-symlinks.js puts the symlinks back afterwards.
