+ Edit and Reset prove their answer against a pending transaction instead of guessing
+ Markers on keys holding a delimiter byte reap like any other
+ OnceAt joins Id and Kind as reserved, overwritten with a warning
+ Warnings rewritten in plain speech, what happened and what to do about it
+ Purchases example answers NotProcessedYet on Unresolved before it reads DidApply
- A marker naming a key with \0 or \1 in it could never be collected by anyone
- A forged OnceAt could wipe the applied id set and pay a delivered transfer twice
- Edit answering true for a verdict a pending leg was about to overturn
- Reserve reporting money set aside without saying on what terms
- Loading and Leaving as two maps that could disagree about one player
! Edit and Reset answer Unresolved when a stuck leg could still flip the verdict
! OnceAt in Fields is overwritten now, CommitOp still honours an op's own stamp
! Mid deploy, a transaction retried across versions can answer Spent once, nothing applies
