# Mirrors the proven stampli-drop-folder pattern. launchd invokes the INSTALLED
# copy at ~/.local/bin/apm-wo-uploader.sh, which must live OUTSIDE ~/Documents:
# macOS TCC denies launchd read access to ~/Documents, ~/Desktop, ~/Downloads,
# and a repo-path script fails silently with LastExitStatus=32256. Re-copy this
# source to ~/.local/bin after editing it.
#
# Uploads new .xlsx/.csv exports to the raw/ prefix using the scoped `apm-wo-drop`
# profile (IAM user apm-wo-drop-uploader — s3:PutObject on raw/ only), then
# archives them locally. The classifier Lambda is S3-triggered from raw/.
