PAG Structure Declaration
Kind: algorithm
Record: algorithms:pag-coordination-construct
Canonical: Algorithms
Closure: Dependencies in load order
Make a document's structure explicit with the declaration that names it: a DAG for a dependency graph, a STATE_MACHINE for a lifetime or a set of derived states, a PRIORITY_QUEUE for a ranking, a FLOWCHART for the rendered projection of a declared structure, and for a shared surface the coordination model's SURFACE, RECORD and ITEM with their typed edges, derived states and the one post-and-wait operation, so ordering, ownership and state are declared as structure rather than narrated as prose.
