 - **甲六「相看似隔前生事」**：原试稿把「似」注作「テ」，没有给整段「前生事 → 隔 → 似」的返读顺序。现标为「似三／隔二／事一」，保留《書き下し》「前生の事を隔つるに似て」的顺序。这是编辑訓，不声称历史传本已有此训点。
 - **乙三「恐花為我辭根」**：原来「恐二／辭レ／根一」未明确显示两个谓语层级。现为「恐三／為レ我／辭二／根一」，表示「花、我が為に、根を辞するを恐る」。不由此确定花被谁折取。
+- **2026-10-15 返点改为高校教科书规范（读序不变）**：相邻一字返读用レ点，二一不相邻；一二点套一二点时外层用上下点；上下点只用在包着一二点时。乙三改「恐二／為レ我／辭一レ根」（字序 花→我→為→根→辭→恐）。甲五小序「記二醉後…始無一レ避焉」（原上下点内无一二点）。甲九小序「得二某所レ寄舊稿一」「與二篋中所一レ存」（原「所二寄一」「所二存一」为相邻一字返读）。这三条规则已写进 `tools/poetry_kunten.py` 的 `check_marks`，正文与标题都校。全库无甲乙点、天地人点：诗句短，最多到上下点一层。
 - **现代汉语专用结构**：撤掉乙三「不是」上的两个机械レ点、甲六「把」上的一二点。两者不能因为网页希望呈现完整小字就伪作教科书式古汉文训法，释义仍交由已经校订的書き下し文。
 - **甲六的词组边界**：在「痴根」的「根」旁标明宾语「ヲ」，避免把「痴根草」误合为一物。但「齧盡」作为复合结果动词尚未用单字返点充分表达，继续列为义训问题，不宣称校勘完成。
 - 编译检查现在逐字固定这两组三／二／一定位，保护「不是」「把」免遭后续自动加点，并验证痴根与草的分界。所有新标记仍按中文正典 SHA-256 锚定。
