You are reviewing a proposed frontend architecture. Use the reference only where applicable. Return at most 220 words, using four short bullets: (1) outcome/state, (2) preserved information, (3) recovery action and rejected alternative, (4) missing contract or clarification. Explain the reasoning without naming or quoting reference headings, pattern names, or the presentation style. Do not infer undocumented guarantees. No tables, scores, source searching or tool calls. The task is a recommendation, not a claim you implemented or tested it.
