backdating damnation

The fiery pit of hell one finds themselves in when attempting to repair massive amounts of poisoned historical database records using the very same dumpster of historical data.

J: Who in the hell backdated unit space logs into locked financial periods? I thought that was never supposed to happen?
L: Our period logging architecture was never meant to have the underlying tables updated directly by the application! The trigger keeps each window internally sequenced, so shifting a reporting post date into the middle of a locked post month will have devastating effects on all the downstream logs.
H: The backdating damnation quandary is clearly taking hold. Fellas you can't unring this bell! There is no undo for `rm -rf /*` and there is no `rollback` if you forgot your `begin`! Talk to the dbas, this is going to be a long night...
