A quest's QuestKind says whose activity advances it and who accomplishes it.

Personal

The member's own activity, for themselves. The member is the subject; the rewards go to them.

Community

A challenge of the whole community: a collective goal — a thousand games this month — that the activity of every member advances. It is accomplished once per occurrence, by the subject community:<quest>, and its rewards go to every member whose activity counted towards it. With OnAcceptance, only the members who accepted it count.

Team

Members join it under a team the application names — team:red, guild:44 —, and their activity adds up towards a goal they share. The team is the subject; the rewards go to the members of the team who still follow it when it is accomplished. A member is in one team per quest at a time, and their activity counts from their own acceptance until their own abandonment.

Duel

A challenge one member sends another on a duel quest, under a key the application gives:

$duels->challenge('duel:812', 'ten-games', $member, $friend);
$duels->accept('duel:812', $friend);    // or decline(); the challenger may withdraw() until then
$duels->standing('duel:812');            // how far each side is
$duels->expire();                        // the offers and the duels whose time is up

• An offer waits for its answer for a lifetime — P7D by default —; accepted late, it expires and the acceptance is refused.
• Once accepted, the duel lasts the quest's duelLength — P7D, PT2H — or until the quest closes, whichever comes first; without either, it lasts until it is won.
• Each side's activity counts from the acceptance to the end; the first side to accomplish the quest wins, which the projection decides: the duel is Won, its winner gets a completion under the duel's key and the rewards.
• A duel whose time runs out with no winner expires when expire() sweeps the duels; the observer is told.

A member may have several duels at once, on the same quest or not; each counts only its own time.
