+#!/bin/sh
+# Pull pinned vendor sources via git subtree. Idempotent.
+#
+# Usage:
+#   scripts/fetch-vendor          # add or update to pinned tag, verify SHA
+#
+# Bump:
+#   1. Pick a new tag from https://github.com/MuntashirAkon/libadb-android
+#   2. git ls-remote https://github.com/MuntashirAkon/libadb-android.git \
+#          refs/tags/<tag>
+#      → copy the commit hex.
+#   3. Update LIBADB_TAG and LIBADB_SHA below.
+#   4. Run this script.
+#   5. Re-prune. This repo keeps only the libadb module plus license files
+#      (vendor/libadb-android/{libadb,LICENSES,COPYING,README.md,
+#      SERVICES.md}); the rest of upstream - sample app, gradle wrapper,
+#      jitpack.yml - is unused. A subtree pull re-adds it; delete it again.
