+
+    The 16.0 hr post-migration (create_work_contact) creates a res.partner
+    per employee taking the partner name from the employee name. Core Odoo
+    accepts nameless partners, but with OCA partner_firstname installed its
+    _check_name constraint raises EmptyNamesError and the whole -u all dies
+    (seen 2026-07-06 on a real 15->16 hop: one active employee with an empty
+    name). Give such employees a deterministic non-empty name first —
+    work_email when available, a synthetic marker otherwise.
+
+    hr_employee.name is a stored related to resource_resource.name, so fix
+    the resource first (source of truth), then the stored column.
+    This file sorts before hr's own pre-migration.py by basename, which is
+    the guaranteed ordering for same-version scripts.
