| Incumbent-parts decomposition | The current bill of materials becomes the functional organization. | Restate the outside effect and develop rival functional organizations before preserving the incumbent allocation. |
| Functional element as purchase item | A box named sensor, protection, or storage is treated as a procurement specification or purchase item. | Recover the function-like claim, candidate actual or intended bearer, interfaces, placement, capability need, and assembly relation. |
| One-to-one allocation | Every contribution is forced into one component and every component into one contribution. | Permit many-to-many and mode-dependent proposals; inspect joint and shared functioning. |
| Diagram overlap as relation | Matching labels or co-located symbols establish identity, allocation, or functioning. | State the direct claim and supporting evidence; keep representation correspondence separate. |
| Interface label as proof | Standard, open, or a connector name establishes compatibility or substitution. | State interface conditions and test conformance, integration, intended interaction, and consequential wrong use separately. |
| Available product as only candidate | Catalogue availability is treated as the boundary of possible construction. | Keep physical candidate generation separate from the choice of obtaining arrangement; use SYSE.24 when that obtaining choice becomes current. |
| Unavailable product as no construction | An unsuccessful search erases candidate bearer descriptions already examined. | Retain the candidates and failure reasons; distinguish market absence, physical infeasibility, and missing project capability. |
| Fewer bearers as automatic improvement | Consolidation or a universal platform is assumed superior. | State transferred contributions, affected characteristics, scale window, losses, and evidence burden; keep it as one candidate. |
| AI graph as design truth | A generated function graph is accepted because it is connected or plausible. | Recover claims and bearers, challenge physical and interface dependencies, and qualify the generator and evidence. |
| Trial as universal proof | One simulation or bench result establishes full functioning and architecture adequacy. | State the Agent, Method, conditions, configuration, observations, claim limits, and the later claim-assessment Work that can use them. |
| Architecture decision hidden in generation | The preferred candidate is silently selected during modeling. | Preserve the decision-usable candidate account, including explicit losses and unresolved claims, as an input to architecture-decision Work governed by SYSE.6. |
| Whole-project stop | One missing bearer blocks every Work stream. | Pause only the unsupported commitment; select another bearer, revise the function, change realization capability, explore, or stop the bounded proposal. |
