C.32:2 - Problem

Architecture synthesis is the constructive middle of architecture work. A practitioner may already know the described holon, architecture question and intended use, some obtaining architecture relations and selected structures, and some concerns, but still need to configure those structures together before later comparison or decision can be honest.

The typical synthesis problem is multi-structure. State each required function or functioning claim through the predicate and bearer recovered with A.6.F. Candidate module, placement, control, transformation-flow, information, evidence, Method, Work, local-kind, classification, or assignment structures may constrain or help explain a candidate, but a kind or assignment establishes no functioning, participation, capability, function bearing, or Work. A control relation can improve supervision while increasing timing or responsibility burden; an information structure can improve maintenance access when exposed through a digital-twin view while still hiding source-return loss; a team structure can improve flow while failing to match module or deployment structure. Every positive responsibility claim still needs its direct domain predicate, actual participants, applicability, and occurrence identity, or the exact A.6.RCD missing governor.

A functional architecture is not enough by itself. A function graph, use case decomposition, workflow, neural cell graph, Method step, or source function from cultural or practice material can enter architecture synthesis only after A.6.F identifies the function or functioning claim and its possible bearer, and after any selected structure or source label is recovered. If no bearer can satisfy the predicate recovered with A.6.F under the relevant module, Method, resource, placement, control, Work, evidence, local-kind, classification, or assignment constraints, the candidate must be repaired before it enters comparison, selection, local choice, or decision work. Those neighboring structures constrain the candidate; they do not bear the function by label.

The typical synthesis problem is also multi-characteristic. Architecture characteristics such as cohesion, coupling, substitutability, evidence reuse, work repeatability, latency, locality, control separation, source-return cost, and composite quality families often compete. Functional demands describe what the holon is to do; architecture characteristics describe whether the selected structures make those demands maintainable, controllable, evolvable, replaceable, inspectable, and otherwise acceptable in the current context.

One recurring candidate-generation heuristic is idealization: ask whether an existing bearer or resource can carry an additional required function under the selected-structure constraints, whether a support bearer can disappear, or whether a more general scale-amenable bearer can replace several special bearers. Admit that heuristic only as a candidate. The candidate must name the functions transferred to a bearer, the bearer removed or generalized, the architecture characteristics improved and worsened, and any BLP scale window or waiver when scale advantage is claimed.

Use C.32 to make the constructive translation explicit. Build a small palette whose candidates answer: which selected structures are configured together, which architecture characteristics improve or worsen, which constraints remain admissible, what source detail must remain recoverable, and which pattern supplies the next claim or test.
