   @ryanmeowy thanks for folding that into the 2a/2b section of the 23 Oct 
table comment — the wording you describe is exactly what I was after: the 
restore decision keys off the split's own watermark pair 
(`SnapshotSplit.isSnapshotReadFinished()`, both non-null), 
`finishedUnackedSplits` is rebuilt from that pair at 
`IncrementalSourceReader.addSplits:152-153`, and 
`restoreCompletedSnapshotSplit` applies the same predicate. That closes the 
question I raised on row 2b; nothing further needed on that point from my side.
   
   One small ask on the same row so the mid-backfill case reads unambiguously: 
please keep the explicit statement that a checkpoint taken during the bounded 
backfill persists the split with both watermarks null (HIGH is only on 
`SnapshotSplitChangeEventSourceContext` at that moment, per 
`MySqlSnapshotSplitReadTask:154`), so a restore re-runs it as 2a rather than 
2b. If that sentence is already in the updated section, consider this done.
   
   On the three contract items — noted that they'll be in the revision as 
agreed; I'll review them there.
