  "_comment": "TESTING.md says this Part 'continues directly from Part 9 Step 9.3' with no reset, relying on ds1's no-common-base state persisting across all four policy steps. Tracing ZFS_Utils.pm confirms the source status file is updated unconditionally for any non-skipped send (even a full send that never lands on the target - see Part 7.2a's own note about this) - so after Step 10.1's own 'allow' send, ds1's recorded resume point would already match its only snapshot, and Steps 10.2-10.4 would find nothing new to send at all rather than re-exercising the no-common-base branch. Per project decision, each step below re-establishes a fresh, genuine no-common-base condition for ds1 (the same recipe Part 9 Step 9.3 uses) immediately before testing its own policy value, rather than relying on carry-over.",
