[business-logic] #1438-A is half-done: bare 'latest' survives next to a comment saying 'the bare forms are dropped' (better WAS narrowed - the asymmetry proves the omission), making the three new phrase shapes dead entries shadowed by the bare match + category dedup; #1438-B repeats the same mistake in CJK: bare 排序/大概/最新的/最近的 substrings with an ASCII-only isWordByte that makes boundary checks always-true for Chinese

internal/agent/ambiguity_point.go L136（裸 {"latest", ambQuantityVague, "how many of the latest items"} 原样保留——L135 裸 recent 同样）对照 L137-141 注释 "#1438-A: ...the bare forms are dropped" 直接矛盾——better 的收窄（L151-155 仅剩 make it/this better 两短语）完成——两词处理不一致坐实半途而废；L142-144（新增 latest items/entries/results 三短语）——L136 裸词先行匹配（afterOK 空格为真）+ L262-269 按 category 去重 → 三短语永不可达为死条目；L170-181（CJK 表——排序 L175/重命名/改名 L176-177/最新的 L178/最近的 L179/大概 L181 均裸子串）+ success_declare.go L255-256（isWordByte 纯 ASCII——CJK 字节 ≥0x80 恒过）→ L203-204 beforeOK/afterOK 恒真——对中文零边界保护；user_sentiment.go L157-158（注释 "REDIRECTION KEYWORDS anywhere...regardless of message length"）对照 L188-198（if isShort { return group.category } 对所有类别生效——L191-194 行内注释反而为此辩护——两段注释互相矛盾）+ analyzeAndUpdate L288-292（返回 "" 即清零 consecutiveNegatives）；unverified_claim.go L229-238（hasVerificationCommands 仅判命令存在——失败的 go test 照样豁免 "tests pass" 假声明）；value_recv_mutation_check.go L204-250（ast.Inspect 全遍历仅跳 FuncLit + vrmExtractRecvField 纯标识符名匹配无作用域/遮蔽感知——if/for 块内 c, err := ...; c.count = 5 遮蔽场景误报 "changes are lost"）

问题

案 A（Med-High·修复半途而废）：#1438-A 未删裸 "latest"——新短语形状是死条目

• FP 面原样保留（"upgrade to the latest version" 零歧义依旧命中+数量建议答非所问）；三条新增短语因裸词先行匹配+类别去重永不可达——本次修复对 latest 等于零改动且注释误导后续维护；测试无裸 latest 用例（grep 实证仅 L60 一条 recent）
  修：删除 L136 裸条目（recent 同议）；补裸词/死条目回归测试。

案 B（Med-High·重蹈覆辙）：#1438-B CJK 裸词——英文刚删的等价模式中文新增

• isWordByte 纯 ASCII → 边界检查对 CJK 恒真=纯子串——"修复排序不稳定的 bug"（已明确讨论稳定性仍命中）、"大概是上个月引入的"（probably 语气副词却给数量标准——答非所问）、"最近的改动导致回归"/"用最新的 API 重写"——主要用户语言为中文误报面大；测试零 CJK 用例
  修：CJK 模式收窄为短语形状（修一下排序/大概多少个 等带宾语形状）；补 CJK 用例。

案 C（Med-Low·注释行为矛盾）：redirection "任意长度"承诺未实现+级联清零

• 长首线纠偏（>100 字符 "Actually, I meant..."）返回 "" → 本该升级的信号丢失+consecutiveNegatives 被抹零——连续两次详细纠偏 agent 却从头按 level-1 温和提示
  修：redirection 豁免 isShort 或更新注释。

案 D（Med+Low）

• unverified_claim 验证存在性对成败全盲（recordToolError 已收集失败数据从未交叉核对——目标场景恰是"跑了失败 test 声称 pass"）；value_recv 无遮蔽感知 shadow 误报（测试零覆盖）
  修：豁免条件加"命令成功"；遮蔽场景保守跳过或作用域追踪。

#1438/#1439 修复区验证（stale 重审）

• [business-logic] attempt_brief iteration-number mismatch: recordOutcome passes i but maybeBrief passes i+1 - failures in the first iteration after a fire hit the watermark blind spot and are dropped (empirically verified: second and final brief never triggers in the common failure-burst-then-quiet pattern); assertion_presence gomega branch is dead code requiring a testing.T receiver that has no Expect method (pure gomega/ginkgo tests judged hollow once wired) #1439 watermark 通过（post-fire 失败不再丢+边界正确+truncateBrief 一致）；[business-logic] ambiguity_point: phrase hits never check whether the ambiguity is already resolved in the prompt - fully explicit 'Rename X to Y in file Z and update references' gets a persistent user-role clarification injection (~150 tokens into history); 'latest' category mismatched to quantity wording; zero CJK patterns = entire zh userbase blind spot; 15-char gate skips 'make it better'/'simplify it' textbook prototypes #1438-C 6 字符门+复数容忍通过；[business-logic] ambiguity_point: phrase hits never check whether the ambiguity is already resolved in the prompt - fully explicit 'Rename X to Y in file Z and update references' gets a persistent user-role clarification injection (~150 tokens into history); 'latest' category mismatched to quantity wording; zero CJK patterns = entire zh userbase blind spot; 15-char gate skips 'make it better'/'simplify it' textbook prototypes #1438-A 不通过（案 A）；[business-logic] ambiguity_point: phrase hits never check whether the ambiguity is already resolved in the prompt - fully explicit 'Rename X to Y in file Z and update references' gets a persistent user-role clarification injection (~150 tokens into history); 'latest' category mismatched to quantity wording; zero CJK patterns = entire zh userbase blind spot; 15-char gate skips 'make it better'/'simplify it' textbook prototypes #1438-B 不通过（案 B）；F3 白名单纯英文（低——中文信息类请求绕过跳过门）。
