 # --- Step 5b: Stable-named installer alias for the website download button ---
-# electron-builder's Squirrel target ignores `artifactName`, so the installer
-# ships as `openswarm-Setup-<version>.exe` (lowercase, version-stamped). The
-# openswarm.com Windows button links to a fixed name, so without this alias
-# every release 404s. The DMG target DOES honor artifactName, which is why
-# macOS never hit this. The alias is a byte copy of the already-signed
-# installer (signature preserved) and is invisible to the Squirrel updater,
-# which keys off RELEASES + .nupkg, not the installer filename.
+# Squirrel names the local installer per `artifactName` (in
+# dist\squirrel-windows\) but RENAMES the published asset to
+# `openswarm-Setup-<version>.exe`, so the fixed openswarm.com download link
+# 404s without this stable-named copy. -Recurse because the .exe sits in the
+# squirrel-windows\ subdir, not the dist\ root. Byte copy keeps the signature;
+# invisible to the updater, which keys off RELEASES + .nupkg, not the filename.
