在完整音节后敲反引号，接着的字母筛这个音节上的字：第一码大小写均可， 紧跟的大写字母是第二码，之后可以接着打，一个输入里可以有多段。开关 helpcode.shuangpin_mid_sentence_helpcode 默认关闭。 约束在整句解码时生效，而不是解完再筛： - Google 解码器在 add_char_qwerty 里送 extend_mtrx_nd 之前按约束过滤词条， 锁住的字带着上下文重新整句解码；约束变化时整段重解，不污染增量搜索。 - kenlm 词格建图时按约束筛边，受约束的跨度不截断地查词库；神经重排只在 词格 n-best 里挑，自动满足约束。 - 普通词条、云和 AI 候选按同一规则收尾校验；满足不了就不出整句。 反引号段在请求里换成手动分隔符，原串留给宿主回读与预编辑显示；选词推进 时剩余音节上的约束随原串保留。输入形状规则放在 contracts/mid_sentence_helpcode.h， TSF、Server、引擎共用，新增 Worker opcode MidSentenceHelpcodeChanged = 28。 googlepinyinime-rev 已与上游解绑，AGENTS 与 UPSTREAM.md 同步说明。
