Structures

Coordination

Some ranger decisions must not merge into several answers. These structures use the sequencer and connected roster to coordinate one outcome.

Claims

Choose one permanent claimant for a named responsibility.

Rule: Accept the first sequenced claim; committed claims are write-once.

OrderedCollection

Give one queued job to one worker without duplicate ownership.

Rule: The sequencer grants each queued item to the first accepted acquire.

TaskManager

Queue volunteers for one role and promote the next connected client.

Rule: A FIFO volunteer queue assigns one client and preserves failover order.

PactMap

Accept a shared setting only after the connected roster signs off.

Rule: A proposal remains pending until every expected client accepts it.
