A monorepo plugin update replaces the plugin directory with the fresh
download and deletes the old copy, taking with it everything the plugin
wrote beside itself. On 2026-10-04 updating calendar 1.2.9 -> 1.2.12 deleted
token.pickle and credentials.json, and the calendar stopped until they were
restored from a backup.
Before the set-aside copy is discarded (store update, reinstall over an
existing copy, install_from_url replace), carry over files the plugin's
.gitignore excludes plus known secret/state files (*.pickle, token.json,
credentials.json, config_secrets.json, .pkce_code_verifier). Files the new
release ships win; byte code and .git are not carried; if a copy fails the
old copy is kept.
The git-pull path no longer sweeps untracked tokens into its auto-stash,
which is never popped.
