A.3:2 - Context

• Holonic substrate. FPF distinguishes what things are (Holon → {System, Episteme, …}) from a System’s classification under local system-role kinds and its obtaining assignments of those kinds (A.2/A.2.1). Only systems can be holders of these assignments, enact methods, and perform Work occurrences admitted under U.Work; epistemes do not act. This work-facing rule does not imply that every actual change has an acting-system side.
• Local kind, assignment, Method, description, and occurrence stay distinct. A local system-role kind classifies Systems by its criterion; an obtaining assignment of that kind is a separate relation (A.2/A.2.1). U.Method is a run-independent semantic way of doing, U.MethodDescription is an episteme that may describe that Method, and each individual admitted under U.Work is the dated performed occurrence that enacts it.
• Run-independent semantics vs dated occurrence. A Method and any episteme that describes it are not the occurrence. When a claim about actual Work is current, its assertion or description designates the Work independently admitted by A.15.1 from its performance history, each performer System’s A.13 basis including the obtaining assignment, actual enacted Method, temporal extent, and containing-System basis. Add F.6 assignment-bound attribution, affected-referent, binding, or resource-use relations only when they independently obtain and the receiving use relies on them. When actual change is also claimed, identify it independently under A.3.4 and use a separately governed work-to-change relation.
• Occurrence, assertion, evidence, and carrier. One Work individual is the world-side occurrence. A separate U.Episteme may assert or describe it and designate the exact occurrence and obtaining relations. Logs, observations, evidence items, and publications have their own carriers and direct relations; neither a carrier nor a record becomes Work by referring to it.
