按指定問題分隔符把批次答案配回原題

訂明本例驗收任務

假設原始答案流用整行 @@Q:ID@@ 開答案，@@END@@ 關答案；編號只用英文字母、數字及連字號。行首反斜線會去掉首字，餘下原樣當內容，即使像標記也一樣。框外非空字留作未配對。嵌套開框、重複已完成編號、無開框的結束、錯標記或未閉框都停解析，保留已完成及未閉內容；不按輸出次序配題。

解析整行開閉標記
轉義行原樣留作內容
保留錯格式及未配對內容

解析錯誤保留已完成答案及現未閉框，須修原始答案流。

使用已填個案

原創假設輸入及確切答案鍵
個案	已提供輸入	預期結構化結果	判斷及原因
Q2 答案先於 Q1	{"raw":"@@Q:Q2@@\nsecond\n@@END@@\n@@Q:Q1@@\nfirst\n@@END@@"}	{"answers":[{"id":"Q2","text":"second"},{"id":"Q1","text":"first"}],"unassigned":[],"open":null,"error":null,"ready":true}	按整行標記配答案編號，不按先後位置。
轉義標記仍是內容	{"raw":"@@Q:Q1@@\n\\@@Q:FAKE@@\n@@END@@"}	{"answers":[{"id":"Q1","text":"@@Q:FAKE@@"}],"unassigned":[],"open":null,"error":null,"ready":true}	行首轉義令看似 FAKE 開框留作答案原文。
未閉答案內又開框	{"raw":"@@Q:Q1@@\n@@Q:Q2@@"}	{"answers":[],"unassigned":[],"open":{"id":"Q1","lines":[]},"error":{"code":"nested-start","line":2},"ready":false}	第二個開框不能默默丟掉 Q1，保留未閉狀態及錯行。
答案框外文字	{"raw":"Intro\n@@Q:Q1@@\nanswer\n@@END@@"}	{"answers":[{"id":"Q1","text":"answer"}],"unassigned":["Intro"],"open":null,"error":null,"ready":false}	Q1 框有效並保留，Intro 未配對，不能列全部已備好。
答案欠結束標記	{"raw":"@@Q:Q1@@\nanswer"}	{"answers":[],"unassigned":[],"open":{"id":"Q1","lines":["answer"]},"error":{"code":"unclosed-block","line":2},"ready":false}	按已訂原始格式，這段答案尚未完整。
編號內有空格	{"raw":"@@Q:Q 1@@"}	{"answers":[],"unassigned":[],"open":null,"error":{"code":"malformed-marker","line":1},"ready":false}	像標記但編號無效的行，不當普通資料文字。
