# Upstream Linkwarden (packages/filesystem/*.ts) resolves STORAGE_FOLDER via:
#   path.join(process.cwd(), '../..', STORAGE_FOLDER, filePath)
# The yarn workspace commands run from apps/web/ or apps/worker/, so
# process.cwd()/../.. resolves to the monorepo root /data_linkwarden.
# Node.js path.join treats absolute path segments as relative when they are not
# the first argument, so an absolute STORAGE_FOLDER like /config/library becomes
# /data_linkwarden/config/library instead of /config/library.
# This affects all filesystem operations: createFile, createFolder, readFile,
# moveFile, removeFile, removeFolder.
# Fix: symlink the top-level directory so all subpaths resolve correctly.
