Master specification of the ZAYAZ Scope 3 micro-engine family: one Post Office (classification), fifteen category controllers, shared method kernels and one Summary engine. Parent document for every Scope 3 engine specification; kernels follow the KISMET kernel framework, with K4 as the all-mode composite transport kernel. Absorbs the withdrawn Scope 3 Category Aggregation and Scope 3 Consolidation specifications.
Assigns every value-chain envelope exactly one governed outcome — a Scope 3 category (1–15), a split, a reroute to Scope 1 or 2, not applicable, or hold — through a deterministic, chart-agnostic decision ladder with full evidence. The single entry point of the Scope 3 engine family.
Rolls category results from the fifteen Scope 3 category controllers into category series, applies the inclusion policy, produces the Scope 3 total and the disclosure object. Successor of the withdrawn Scope 3 Category Aggregation and Scope 3 Consolidation specifications; inherits MEID_GHG_AGGR_SCOPE3 from Scope 3 Consolidation.
A spend-based emissions factor engine enabelling automatic Scope 3 estimation from procurement spend.
