### One version of a card's content, never changed once written (ADR 0001,
|
||
|
|
### rule 2): editing appends a revision whose parents are the versions it
|
||
|
|
### replaces, and a card's current versions are the revisions no other
|
||
|
|
### replaces. Deleting a card blanks every revision's payload first (ADR 0002,
|
||
|
|
### rule 2).
