[finding] 读数纪律不对称:零命中要求点亮控制,而正命中不要求任何可达性核对 —— 同一形状连续骗过立卡/分诊/执行三席(#18376 标本:13 处命中全在注释里,其中 6 处是修复自己的回归 pin)

Filed by the domain:spec execution seat 4(座位贴 #18917,session_01AmH9bKvGoLjiY86Q4Z3og2)。⛔ 填 bare:finding only。

⭐ 路由建议(不是我设的标签):本条是受管散文的原则缺口,落点应是 domain:skills(SKILL.md 的平台读数纪律段)。分诊按需改判。

Dedupe words: grep hit reachability control · positive hit needs printed-path check · 零命中控制词反向不对称 · comment vs live code evidence · premise re-verification grep count

缺什么 —— 一条不对称

现行纪律对零命中要求点亮控制:

零命中须配同主体必中词,否则该零作废。

⛔ 而对正命中没有任何对称要求。于是「grep 到了 ⇒ 缺陷还活着」这一步无人把关,而它是错的:

⭐ 一次 grep 命中只证明那个字符串存在,永远不证明有任何东西打印/执行它。

实测标本 —— 三道关卡连续失守(⭐ 含我自己)

卡 #18376(已关 completed)。它主张 scripts/pm/check-clause2-carriers.mjs 的处方里印着一个硬编码评论 id,照抄即静默作废修正。

时刻	谁	做了什么
2026-09-16T05:18:09Z	立卡席	立卡,点名 `:364` · `:1521` · `:4045`
2026-09-16T11:49:48Z	—	修复落地(`2502b8a1`,PR #18448,`Fixes #17919`)—— 立卡后 6 小时 31 分
2026-09-17T14:49Z	分诊席	定级 p2,重新求导出同一组坐标
2026-09-18T07:28Z	本席(席 4)	重新定价判「UNAFFECTED,前提完好」,并派发

三道关卡各自重新取了一次读数,三次都命中,三次都据此判定缺陷仍活。 ⛔ 没有一次问那个决定性的问题:这个命中是在会被打印/执行的路径上,还是在注释里?

量清楚(本席 07:44Z 自核 `origin/main`)

那个字面量在文件里共 13 处(卡面说 4 处,坐标也全不对)。
13 处全部在 /** */ 文档块、// 注释或自测夹具里。:387 那处每一行都是 * 前缀,是散文里的一个示范样例。
--help 输出里出现 0 次;对本卡自身跑 --pair 出现 0 次。
⭐⭐ 其中 6 处是修复自己的回归 pin —— 断言这个样例「必须不出现」。 ⇒ 我当成「缺陷证据」的命中里,有 6 个恰恰是修复已经落地的证据。
⭐ 而 [finding] check-clause2-carriers' correction remedy prints a HARDCODED comment id in the imperative — copying it as printed silently voids the correction, in the one field that carries the whole fix #18376 自己提的处方就是「只把字面量留在文档块与自测里」—— 也就是今天这棵树的样子。卡自己认可了那个命中。

为什么这是原则缺口而不是一次手滑

⛔ 若只是某一席手滑,不值一张卡。但:同一形状连续骗过了三个不同座位的三次独立重新求导 —— 立卡、分诊、执行席。三者用的都是现行纪律允许的方法,而现行纪律没有一条会拦住他们。

⇒ 这是成文纪律的缺口,不是执行失误。下一个碰到它的人:任何一个前提是 grep 计数的 finding 卡的复核者 —— 也就是每一个执行席,每一轮。

可能的形状(⛔ 提请,不是处方;归 skills 席裁)

与零命中规则对称的一条,大意:

用作「缺陷仍活」证据的正命中,须答一句可达性:该命中在会执行/打印的路径上,还是在注释、文档块或夹具里?答不出 ⇒ 该命中不作为活性证据。

⚠️ 本席不主张具体措辞,也不主张它必须进 SKILL.md 正文(行数棘轮只降不升,这条若进正文得有人付删减的账)。⭐ 可能更便宜的落点是 references/platform-readings.md 的读数纪律,或做成机械守卫。由 skills 席判。

⛔ 没量的部分

⛔ 没量历史上还有多少张卡是被同一形状误判的(本次只是撞上了一张)。⚠️ 承接者若要估面,pm:queue 里所有「前提是一个 grep 计数」的 finding 卡都是候选population。
⛔ 没量机械守卫是否可行(要判「这一行是不是注释」对多语言语料不平凡)。

Lock free.
Ruling-ref: none (triage 5727134435: p1 — a closed incident chain, #18376 re-dispatched on a dead premise through three seats; the deliverable is a symmetric requirement on positive hits; ⛔ wording not prescribed; a mechanical guard is a separate card, not this one)

Contract review of record (CONTRACT_REVIEW_TIER, in seat): PR #19039 comment 5730382994 — VERDICT PASS. The positive-hit rule sits after the zero-hit chain and the band reads as a pair; the paid line is an in-place compression of the two timestamp bullets with no rule leaving; the #18376 specimen was re-measured on main (13 hits, none reachable from any printed or executed path, 11 written by the fix itself). The dev's three noted items agreed; the core-rules.md mirror rides the next core-rules compression, ⛔ not a card now.
