+## Step 7b: Validate release config scripts
+
+Verify that all script references in release-related config files point to files that actually exist. Broken references cause silent failures during `npm run release` or the publish workflow.
+
+Check these files for script paths:
+
+```bash
+# .versionrc.json — check any "scripts" entries (runner and forwarded args)
+grep -oP 'node \K[^ "]+' .versionrc.json 2>/dev/null | while read script; do
+  [ ! -f "$script" ] && echo "ERROR: .versionrc.json references '$script' but it does not exist"
+done
+grep -oP 'node [^ "]+ \K[^ "]+' .versionrc.json 2>/dev/null | while read script; do
+  [ ! -f "$script" ] && echo "ERROR: .versionrc.json references '$script' but it does not exist"
+done
+
+# package.json — check version/preversion/postversion lifecycle hooks
+grep -E '"(pre)?version"|"postversion"' package.json | grep -oP 'node \K[^ "&]+' | while read script; do
+  [ ! -f "$script" ] && echo "ERROR: package.json lifecycle references '$script' but it does not exist"
+done
+
+# Also check forwarded script arguments (e.g. "node scripts/node-ts.js scripts/foo.ts")
+grep -E '"(pre)?version"|"postversion"' package.json | grep -oP 'node [^ "&]+ \K[^ "&]+' | while read script; do
+  [ ! -f "$script" ] && echo "ERROR: package.json lifecycle references '$script' but it does not exist"
+done
+```
+
+If any script reference is broken, fix it before proceeding. Common causes:
+- `.js` extension referencing a `.ts`-only file (use `node scripts/node-ts.js scripts/<name>.ts` instead)
+- Redundant script entries that duplicate what npm lifecycle hooks already handle (remove them)

 ## Step 8: Create branch, commit, push, PR
 
 1. Create branch: `git checkout -b release/VERSION` (if on detached HEAD from Step 0, this creates the branch at the current commit)
