C.25:20b - Architecture-decision Q-Bundle boundary

C.32.P2S, C.32.PAD, and C.32.ADA may cite exact C.25 quality-claim epistemes or ClaimAddresses as architecture-characteristic inputs, accepted-loss structure, guardrail rows, feedback concerns, or adequacy concerns. C.25 keeps their Q-Bundle claim content, bearer, scope, measures, mechanisms, qualification window, and evidence distinct from the problem-to-structure architecturing flow, project architecture decision relation, and ADR-like publication projection.
