# One-time port of Odoo Enterprise Planning data into the native Fusion Clock
# models, so a deployment that previously used the `planning` bridge keeps all
# its roles, employee role assignments and shifts after `planning` /
# `fusion_planning` are removed.
#
# Guarded: a no-op on Community / fresh installs where planning data is absent.
# Idempotent: a marker param stops it re-running.
