Terms used in this paper

Terms defined where they first appear are not repeated here.

• Fulfillment: carrying approved demand through allocation, delivery and turn-up to use (Figure 15, steps 3–6).
• Apportionment: spreading cost; where a cited source means this, it's written cost allocation.
• Commit, commit point: a supply order or promise, and the last date it can be placed; not the capacity reservation, temporary or static, that the SRE chapter calls a commitment [7].
• Unallocated line: unattributable cost, apportioned by declared policy (the cost-tool sense, not the physical one). Like the unused line, it is owned (mechanism 4).
• Cut line: divides a ranked list of asks into funded and unfunded.
• Forum: the standing executive body that owns the ranked list and the cut line (mechanism 10).
