格式修正要有次數上限，也要保留資料

訂明本例驗收任務

假設本機格式修正最多兩次，先有已核實的非空文字編碼，每次也須有非空文字編碼及布林格式標籤。編碼完全相同，格式為真才完成；即使格式對，改了編碼仍是依據錯誤。兩次都無效便停止，之後的記錄不當作容許範圍內的嘗試。

最多查看兩次修正
先核保留資料，再看格式
列完成或停止原因

改了已核實資料便停止，次數用完仍錯交同事覆核。

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
第二次格式修好	{"verifiedCode":"K7","attempts":[{"code":"K7","valid":false},{"code":"K7","valid":true}]}	{"status":"complete","attemptsUsed":2}	第二次在上限內通過，並保留 K7。
格式好了卻改編碼	{"verifiedCode":"K7","attempts":[{"code":"K9","valid":true}]}	{"status":"fact-changed","attemptsUsed":1}	格式有效不能批准替換已核實資料。
文字 false 不是格式布林	{"verifiedCode":"K7","attempts":[{"code":"K7","valid":"false"}]}	{"status":"invalid-format-label","attemptsUsed":1}	文字 false 不能按真值當已完成依據。
兩個編碼都未具備	{"attempts":[{"valid":true}]}	{"status":"missing-code-evidence","attemptsUsed":0}	undefined 相同不是保留已核實編碼的依據。
該次欠保留編碼	{"verifiedCode":"K7","attempts":[{"valid":true}]}	{"status":"missing-code-evidence","attemptsUsed":1}	格式為真也不能完成欠保留編碼的嘗試。
第三次超過上限	{"verifiedCode":"K7","attempts":[{"code":"K7","valid":false},{"code":"K7","valid":false},{"code":"K7","valid":true}]}	{"status":"stopped","attemptsUsed":2}	第三次雖成功，也超出本例兩次規則。

{"status":"stopped","attemptsUsed":2}。第三次雖成功，也超出本例兩次規則。
