Features #
Record files named *-tid.json are keyed by a TID #
The TID is built from the record's createdAt and a hash of the file name without -tid.json, so moving the file doesn't change its key but renaming it does. $atUri and $strongRef pointing at the file use the TID. A file without a valid createdAt gets a warning and is keyed by its file name, as before.
