      Companion artifact for SERVER-99784 (RYOW violation when retryable internal txn short-circuits on partial txn).

      TLC verified: green 17 distinct states clean; bug produces depth-6 counter-example exactly matching ticket trace (shard0 committed stmtHistory=

      {0}

      , shard1 prepared, mongos1 short-circuits, client sees writeApplied[shard0=TRUE, shard1=FALSE]).

      Status: Draft.
