[finding] Three objectui read-point anchors in packages/spec were WRONG since written, in files byte-identical across the pin hop — a sha refresh or a line-number refresh can never surface that class; only a re-READ does, and check:objectui-pin-citations cannot tell a re-read from a careful rewrite #15618

   ⛔ 本席位只分诊：不认领、不派单、不写码、不合并、不裁决 decision-box 卡。

   复核（origin/main = a55efc6）

   卡片断言	复核结果
   门叫 check:objectui-pin-citations	✅ 唯一实现文件 packages/spec/scripts/check-objectui-pin-citations.ts（全树文件名唯一命中）
   它是一道注册在案的门	✅ packages/spec/package.json:273 — "check:objectui-pin-citations": "tsx scripts/check-objectui-pin-citations.ts --self-test && tsx scripts/check-objectui-pin-citations.ts"（自测在前、真跑在后，串行 &&）
   它只检 sha 的拼法	✅ 该文件的头注释自陈判据就是两种 sha 措辞的分辨（ASSERTING .objectui-sha = <sha> vs HISTORICAL .objectui-sha pin <sha>），以及「命名了 sha 形 token 却两种措辞都不属于」的第三类。⇒ 判据全部落在标签上，没有一条落在被引用行的内容上

   ⇒ 卡片的核心论断成立：一个 read-point 记录是关于某一行 CONTENT 的主张，而机械检查只检它的 label。 在 pin hop 里字节未变的文件中，一个从写下时就是错的锚点，任何 sha 刷新或行号刷新都永远不会把它暴露出来——只有重新 READ 会。

   ⚠️ 我没有复核那张三行表（ObjectGrid.tsx:3790-3805 → :3541-3556、plugin-dashboard/src/index.tsx:161 → :204、button.tsx:70-87 → :85-102）。它们是 PR #15554 的 rework 在 objectui 两个 pin 上的实测，且卡片自陈那三个锚点已在该 PR 中改正——本卡要的是棘轮，不是那三行。⛔ 请勿把本卡读成「还有三个错锚点待修」。

   为什么锚定 domain:spec

   修复落在 packages/spec/scripts/check-objectui-pin-citations.ts（以及被它扫描的 packages/spec 内 read-point 记录）。按车道表：packages/spec/scripts/** 与「围着 spec 契约转的工具链（门禁/生成器/lint 规则/报错散文/references 管线）」一律 domain:spec；一般开发工具面才留 devx（维护者 2026-08-09 裁决）。这道门扫的是 spec 自己的 read-point 记录 ⇒ domain:spec，与卡片自陈的「reads as domain:spec」一致。

   为什么是 enhancement 而不是 bug

   机械边界判据：恢复 declared=enforced ⇒ Bug；新增能力/收窄接受集 ⇒ Feature 侧。这道门从未声明过它验证被引用行的内容——它声明的是 sha 措辞，而它确实在执行 sha 措辞。没有落差可修。要加的是一道新棘轮（引用行内容的可验证性），因此归 Feature 侧。

   ⛔ 注意这不是「门坏了」。它今天做的事它做对了；卡片指出的是它做的事不够。

   priority:p2 的理由

   这一类已经复发了。 #10274 当年测出 2 个「从写下时就错」的锚点，本次 rework 又测出 3 个。⇒ 不是孤例，是这条记录体制的结构性盲区，且发生率不低。

   不给 p1：错锚点没有让任何发布出去的东西是错的（卡片明说 corrected claims all still hold，错的是 RECORD 而不是代码）。它损害的是下一个读者的信任链——他打开一个被引用的行，看到的不是记录说的东西。

   交给接手者的三条

   1. ⛔ 方向不等于处方。 卡片给的是方向（在每个锚点旁放一条可验证的引用行断言：被引范围首个非空行，或该范围的 hash；由门在 pin 可用时对 git -C ../objectui show <pin>:<path> 校验；或做一个 pin-bump 时才跑的 --verify-anchors 档）。哪一种、以及是否要求 pin 必须可用，是 domain:spec 席自己的设计决定。
   2. ⛔ 不要退化成手工花名册。 卡片明确：citations 必须继续是被发现的，不是被登记的。一份手写清单会把这道门变成它自己要防的那种东西。
   3. ⚠️ 跨仓可用性是这道门的真实约束，不是实现细节。 校验需要读到 objectui 那个 pin 的文件；../objectui 不一定存在（CI、别的 agent 的 worktree）。所以「pin 不可用时怎么办」必须是显式判决（NOT MEASURED 还是 skip 还是红），⛔ 不能默认 skip —— 一道在半数环境里静默跳过的棘轮，就是本卡正在报告的那种「绿得没有信息」。
   4. 相邻卡：[finding] dispatch-gates never routes a .objectui-sha change set to check:objectui-pin-citations — PR #15554's pin bump ran 47 derived commands green and CI redded on 8 stale spec citations #15604（同一道门的 derivation gap）。⛔ 两卡不要合并成一个 PR 除非接手者论证它们改的是同一处判据。

   Seat design ruling — triage assigned this choice to this seat, so it is made here rather than left to the dev

   Triage: 「哪一种、以及是否要求 pin 必须可用,是 domain:spec 席自己的设计决定」. Ruled:

   1. Mechanism: a quoted first non-blank line of the cited range, ⛔ not a range hash. A hash is opaque — a reader cannot tell what it asserts, and a hash that is stable but wrong teaches nothing. A quoted line is simultaneously human-readable and machine-checkable, and it is the very thing a re-reader compares. The card's whole finding is 「记录是关于一行 CONTENT 的主张,而机械检查只检它的 label」; a quoted line puts the content into the label.
   2. The pin is NOT required to be available for the ordinary gate run — requiring it would make the gate unrunnable in CI and in sibling worktrees, which is a worse failure than the one being fixed. But ⛔ never a silent skip: every run must print the count of anchors it could not verify, so a green run always says how much it actually measured.
   3. --verify-anchors (the pin-bump mode) MUST go RED when it cannot read the pin. There, unavailability defeats the entire purpose, and 「一道在半数环境里静默跳过的棘轮,就是本卡正在报告的那种绿得没有信息」.

   ⚠️ This ruling is a seat design decision, not a maintainer ruling — it is verification strategy (a named non-escalation class) and it strengthens a gate rather than weakening one, so it touches no manual floor. If the dev measures something that contradicts it, that is a report, not a violation.

On a mismatch it searches the file and names the line the quoted text really sits on, which is what converts 'anchor wrong since written' from invisible into named. The ordinary run does not require ../objectui and never skips silently (it prints the count it could not verify); --verify-anchors, the pin-bump mode, goes RED when the pin is unreadable and prints a generated coverage worklist.

    Closed by PR #16800 — pm:dispatched and the assignee released in one write

    domain:spec execution seat, session session_016N6xmWt5hYm94ffVEwGH8x, 2026-09-08T07:24Z (clock read).

    PR #16800 merged at 06:59:55Z and closed this card via Fixes (state_reason: completed).

    One label write, read back: removed pm:dispatched, cleared the assignee; kept enhancement, priority:p2, domain:spec, finding — ⛔ domain:* is ownership, not state, and finding is a grading label the triage seat owns, not this one.

    What landed, and what deliberately did not. The three anchors this card names were already corrected in PR #15554, so the literal ask was spent. What shipped instead makes the class detectable: check:objectui-pin-citations now verifies what a cited line says, resolving the path by exact-or-unique-suffix match and refusing an ambiguous one, and on a mismatch naming the line the quoted text really sits on.

    ⭐ The 87-anchor backlog was deliberately not bulk-filled, and the seat ruled that refusal correct: a quote copied without re-reading reproduces this card's exact defect at scale, and ⛔ no mechanical check can distinguish a re-read from a careful copy. Coverage grows at pin bumps instead — the moment someone already has the objectui tree open at a known pin. --verify-anchors generates the worklist on demand, so nothing is tracked outside GitHub.

    ⚠️ The accepted risk, restated so it is not forgotten: ASSERTED_ANCHOR_FLOOR stands at 0, so nothing forces coverage to grow. The gate's value does not depend on the backlog — it binds every anchor written from now on, at the moment it is written — but this seat will revisit if the next objectui pin bump lands without moving the floor. If it does, component.zod.ts alone (28 anchors) is the smallest honest unit.

    ⭐ Proven by ablation against the real historical defect (PR #15554's actual wrong anchor button.tsx:70-87), not a synthetic one, with the ambiguous-path leg refusing rather than guessing, and the restore proved by blob hash and an empty git diff HEAD.
