Keep this file out of the test conversation.

MERGE-01
Keep 007,Sample A,Mina and 7,Sample B,Sol. The leading zeros are
part of the key. Do not normalize 007 to 7.

MERGE-02
Keep one K12,Sample C row with an empty owner and flag the Ari/Ren
conflict separately. The source does not support choosing either owner.

MERGE-03
Keep L3,Sample D with an empty owner and L4,Sample E,Jo. Do not
infer an owner for L3 or remove it from the base set.

Equivalent formats are acceptable if they preserve the base keys,
the specified blanks, and the unresolved conflict.
