With precise checkpoint and preserve prepared on, we  want to add to test/checkpoint the ability open the live database, claim the prepared update and then do the validation.

Some discussion points from a chat with Jie and Sid when going through the discussion about precise checkpoint to consider:

Checking if reconciled data before stable timestamp is done in test/format (how about prepare?) - Done through Mirrored table

• What if all mirrored tables are reconciled wrongly? (Testing gap (Infrastructure is not there))
  Scenario: Recovery + Review all claimed prepared transactions (Randomly rollback/commit?)
• Rule?: Open cursor and insert is this allowed -> check pls
• Testing coverage: All mirrored tables should have the exact same claim prepared data.
• What if all tables are wrong? (Testing gap) (Testing gap (Infrastructure is not there))
  To cover testing gap use _abort csuite tests:
• Making sure all data is reconciled properly? Add Prepare ID file, commit (Preserve prepare) * Record all data before stable timestamp -> crash -> make sure all correct data is there (Add support for precise checkpoint)

• Can we check if pending prepared before stable timestamp is checkpointed?
