+Hiding the review workflow is not the same as forbidding it. The
+``action_timesheet_*`` methods stay callable from code, from a server action or
+from another module, so a sheet can still go back to ``confirm`` through a
+non-interactive path. That is deliberate, for compatibility with the rest of the
+family. An installation that needs to really forbid it would need a separate
+module.
+
+The modules of the family that take the review workflow for granted lose their
+purpose with this one installed. They do not break, because the methods are
+still there, but they become unreachable from the user interface:
+
+* ``hr_timesheet_sheet_policy_department_manager``
+* ``hr_timesheet_sheet_policy_project_manager``
+* ``hr_timesheet_sheet_autodraft``
+* the ``action_timesheet_confirm`` check of ``hr_timesheet_sheet_attendance``
+
+Unfreezing cannot be undone. Uninstalling the module brings the buttons back,
+but the sheets that were already set back to draft stay in draft, and the four
+menus of the review workflow stay deactivated: they belong to the base module
+and Odoo does not restore a value written on a foreign record.
+
+The ``Timesheets to Review`` action of the department kanban loses both of its
+entry points, but the action record itself survives, because
+``ir.actions.act_window`` has no ``active`` field to switch off. It is only
+reachable from Settings > Technical > Actions, and its stale
+``search_default_to_review`` context key no longer matches any filter.
+
+With the sheets back in ``draft``, every save triggers the base module's
+``delete_empty_lines(True)``, which removes lines with no description and no
+hours. This is pre-existing behaviour, but it may prune historical empty
+entries the first time those sheets are opened.
