Start at the SqlAGReplica resource and its parameter definitions, then compare the requested SESSION_TIMEOUT setting with the SQL Server 2016 availability-replica options and the installed SqlServer module. Confirm whether the resource should expose this setting; done means the supported or unsupported status is documented and any required resource coverage is updated.
