SYSE.2:4.6 - Stop at a grounded architecture question and reopen from failed support

Stop when the current use claim and candidate concept expose a grounded architecture question and their main uncertainty. The linked proposal supplies required functioning, operating conditions, outside effects, decision-relevant environment structures, assumptions, and evidence limits to C.30 and C.32.

Use C.30.ASV only when a structural description and its adequacy for a selected architecture use are current. Do not open a full view or architecture-description apparatus merely because a sketch helped the discussion.

Reopen the smallest linked claim when:

  • the use claim and concept claim no longer support each other;
  • a candidate architecture lacks a feasible bearer or hides a harmful effect;
  • realization evidence defeats an interface, resource, placement, or capability assumption;
  • operating observation changes a condition or effect; or
  • a specialist result changes permission, feasibility, harm, value, or the participating Work arrangement.

Return to SYSE.1 only when the failed claim changes which System should orient the project or where the project boundary lies.
