Decompose one capability area's requirements for one change into implementable tickets with Priority, Value, acceptance criteria, Prior Art, Output contracts, Known Hazards, dependency ordering and relative sizing: one TICKET-NNN.md per ticket plus backlog.md, in the change's tickets directory. Use when a specification is approved and the team needs work items, such as 'break this spec into tickets' or 'create the backlog for search'. Not for implementing a ticket (delivery) or ordering whole capability areas (dependencies).
