CALL NUMBER: deep_happens_before_relat.happens_before_order
DEFINITION: A transitive, irreflexive partial order over operations in a memory model that defines which operations must appear to precede others from any thread's perspective.
Invoke this skill to understand happens_before_order down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.
THE RELATIVE ROOT (the import cone, by lib)
CONSUMERS (what needs this)
hb_causality_order, hb_synchronization_order, inter_thread_happens_before, synchronizes_with_ordering_effect
Projected from the concurrency synchronization primitives and memory models KB (407 concepts / 477 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.
(leaf — this is an actual skill.)
