A DROP / CREATE / UPDATE sequence can resurrect a dropped table when the checkpoint schema epoch falls between the DROP and the later CREATE of the same table name. At that checkpoint epoch, the old generation should be gone and the new generation should not exist yet.

In this bug, the checkpoint correctly defers the new generation’s CREATE as too new for its epoch, but still applies that same generation’s UPDATE. That UPDATE publishes shared metadata for the new generation, so recovery at the checkpoint epoch reconstructs a table that should not exist there.

Worked example:

epoch 5: DROP table T, generation A, table ID 100
epoch 6: checkpoint epoch
epoch 7: CREATE table T, generation B, table ID 200

At checkpoint epoch 6, table T should not exist:

REMOVE generation A, epoch 5:
    checkpoint epoch >= 5, so apply it.
CREATE generation B, epoch 7:
    checkpoint epoch < 7, so skip it.

The bug was:

UPDATE B, epoch 6:
    applied even though B's CREATE was skipped.

That UPDATE wrote shared metadata pointing T at unpublished generation B, so recovery incorrectly saw T.

With the fix:

UPDATE B:
    skipped while B's CREATE is pending.
checkpoint at epoch 7 or later:
    CREATE B is published, then UPDATE B is allowed.

What the code needs to take into account:

Table names can map to multiple generations. When replaying a checkpoint UPDATE, skip it if its table ID matches a deferred CREATE for the same name.
