From 76c9b6a4a4cd8dd3405732b9aab1db1ff1ccdedd Mon Sep 17 00:00:00 2001 From: Danno Ferrin Date: Thu, 20 Jun 2024 10:20:40 -0600 Subject: [PATCH] Check for EOFCreate subcontainer rules (#7232) Check and test for the unused container rule, and only returncontract targets can have truncated data rule. Also test the other subcontainer rules in unit tests.
