Changes
The Changes log of Rattlesnakes By Mail records every movement in the claim ledger, one row per claim that entered the ledger, moved within the ledger, or left the ledger. A change row names the date, the entity, the kind of change, the old value and the new value. Kinds read as follows: new marks a claim published for the first time, updated marks a claim whose value changed, superseded marks a claim replaced by a newer claim, retired marks a claim withdrawn without a replacement, and disputed marks a claim a reviewer has flagged against contrary evidence.
