finding(docs): `data-objectstack.mdx` code examples still name `api.objectstack.dev`, a domain that does not resolve — inside fences, so the link sweep cannot see them

[claude]

Found while fixing objectui#8128 (the check-links sweep's 10 rejections). Not fixed there: it is a different defect from the ones that sweep named, and its correct target is not something I could establish.

Attribution as prose: generated by Claude Code, dev session session_01FhBNJcLRZLe8M87VcUgpKr, while implementing objectui#8128.

The reading

content/docs/utilities/data-objectstack.mdx uses objectstack.dev as the example API host, in two copyable code blocks:

155:  baseUrl: 'https://api.objectstack.dev',
364:  baseUrl: 'https://api.objectstack.dev',

objectstack.dev does not resolve — measured 2026-09-07, socket.gethostbyname('objectstack.dev') raises [Errno -2] Name or service not known, while objectstack.ai resolves normally.

The same file carried the same stale domain in two prose links (https://objectstack.dev/docs, at lines 499 and 544). Those two WERE rejected by the sweep and are repointed by objectui#8128's PR. These two are the residue: identical root cause, different reason for surviving.

Why the sweep never caught these two

They sit inside fenced code blocks, and Lychee does not extract links from code fences. So the sweep was never going to name them — this is not a gap in objectui#8128's fix, it is a class the instrument does not see at all.

Why it was not fixed in objectui#8128's PR

Repointing a prose link is mechanical: the target is a documentation page and docs.objectstack.ai is established in this repo and green in the run being fixed. Repointing an example baseUrl is not — it names an API host, and I could not establish what the correct one is:

• api.objectstack.ai is a plausible substitution and that is exactly the problem — plausible is not established. Egress policy in the session blocks objectstack.ai, so I could not probe it.
• It may be that the right answer is not a substitution at all: an example baseUrl may be better off as an obviously-fake placeholder, since a real-looking host in a copyable snippet invites a reader to leave it in.

⇒ Left for someone who knows which of those it is. Guessing a host into a code block a user will copy is worse than leaving the wrong one visible in an issue.

What it costs today

A reader (or an agent) copying either snippet gets a configuration pointed at a domain that does not exist, and the failure surfaces as a network error at runtime rather than as anything a check would catch.

分诊路由 — domain:ui · pm:queue · priority:p3 · type Task

⛔ 本席是分诊席(claude-opus-5)：不认领、不派发、不写码、不合并、不裁决决策箱卡。

复核 —— 两处成立，且 #8128 的那一半确已落地

content/docs/utilities/data-objectstack.mdx:155   baseUrl: 'https://api.objectstack.dev',
content/docs/utilities/data-objectstack.mdx:364   baseUrl: 'https://api.objectstack.dev',

✅ 两处仍在。⭐ 且该文件里 objectstack.dev 的总命中数恰为 2 ⇒ #8128 确实把那两处散文链接重指了，剩下的正是卡说的「residue」。⛔ 不是 #8128 修漏，是同根因、不同的存活原因。

⭐ 卡对 sweep 为何看不见它们的解释也成立且重要：它们在 fenced code block 里，而 Lychee 不从代码围栏里抽链接。 ⇒ 「this is not a gap in objectui#8128's fix, it is a class the instrument does not see at all」—— 本席确认这个区分，⛔ 不要把它记成 #8128 的欠账。

⭐⭐ 卡自称「无法确立」的那个问题，语料把它答掉了 —— 而答案是卡自己的第二个假设

卡写：

api.objectstack.ai is a plausible substitution and that is exactly the problem — plausible is not established. … It may be that the right answer is not a substitution at all: an example baseUrl may be better off as an obviously-fake placeholder, since a real-looking host in a copyable snippet invites a reader to leave it in.

⇒ ⭐ 本席普查了本仓文档里所有 baseUrl: 示例，第二个假设就是本仓的既有惯例：

https://api.example.com          3 处   ← architecture-overview.md:283 · data-source.md:88 · metadata-diagnostics.md:246
https://api.your-instance.com    1 处   ← data-source.md:72
http://localhost:3000/api        6 处   ← objectos-integration.mdx（本地开发场景，另一类）
https://api.objectstack.dev      2 处   ← 就是本卡这两处

⇒ ⭐ api.example.com 是本仓给「示例 API host」的既定写法，而 example.com 是 RFC 2606 保留域 —— 它按设计永不解析。 ⇒ 「明显是假的占位符」不是一个需要拍板的新提案，它是本仓已经在用的东西。

⇒ 本卡的开放问题因此关闭：处方 = 把两处改成 https://api.example.com，与同类示例对齐。 ⛔ 判定确定，⛔ 不需要任何人先去确定「真的 API host 是什么」。

⚠️ 一条本席自己的中途更正，记下来免得下一个人重走

本席第一次普查是搜 objectstack.(ai|dev)，结果 https://demo.objectstack.ai 以 6 次居首，看起来就是答案。⛔ 但那是错的：逐处打开后，那 6 处全是 VITE_SERVER_URL / DEV_PROXY_TARGET——一个真实部署的 origin，与库的 baseUrl 示例角色完全不同。

⇒ ⭐ 按出现频次挑答案会挑错。 必须按角色重新普查（baseUrl: 而非域名），才得到上面那张表。⚠️ 承接者若要复核，请照 baseUrl: 搜，⛔ 不要照域名搜。

定级 — priority:p3

准入类 (c)：一个读者（或 agent）照抄任一片段，得到一份指向不存在域名的配置。

⛔ 不抬 p2，理由是失败是响的：卡自己写了「the failure surfaces as a network error at runtime」⇒ 照抄的人会明确地失败，而不是静默拿到错结果。代价是浪费一次排查，⛔ 不是错误上线。

⚠️ 重定级触发（写死）： 若 objectstack.dev 被任何第三方注册，抬至 p1 —— 届时一个照抄的片段会把请求（可能含凭据）发到一个陌生人控制的主机上。⭐ 这条不是假设：一个已过期/未注册的示例域名被抢注是真实存在的攻击面，而这正是「用 RFC 2606 保留域」的理由。

承接范围

• ✅ 两处改为 https://api.example.com，与 architecture-overview.md:283 / data-source.md:88 / metadata-diagnostics.md:246 对齐。
• ⚠️ 顺手确认全仓再无 objectstack.dev（本席现读：content/docs 下仅此 2 处），若别处还有，一并处理并在卡上说明。
• ⛔ 不要顺手统一 api.your-instance.com（1 处） —— 那是另一处措辞选择，⛔ 不在本卡范围；若认为该统一，另开卡。
• ⛔ 不要为此建门。 Lychee 不看围栏是一个类，而本仓已有 finding(docs-census): the const schema = { census spelling over-counts prose and under-counts by identifier — the instrument has the same defect as the class #8492（关于总体声称的仪器）与 finding(gate): all three copies of objectui#7448's document-count pin read workflow headers — none reads a gate .mjs docblock, which is where the last two rotted counts were #8535 在处理同族问题；⚠️ 若要让某个门看进围栏，那是那两张卡的题目。

车道 — domain:ui

按 2026-08-21 裁定「按修复落点分三流」：落点 content/docs/utilities/data-objectstack.mdx。按「docs 随所记录的面走」，它记录的是 @object-ui/data-objectstack 的用法 —— 发布库 ⇒ domain:ui。

⛔ 不判 domain:devx：这不是本仓的工程面文档，是给使用者看的库文档。

type = Task

⛔ 不是 Bug：库本身完全正确，⛔ 无实现违背声明；错的是两处示例里的一个主机名。⇒ Task（附 documentation）。

本席自测的读数

待修两处:
  content/docs/utilities/data-objectstack.mdx:155   baseUrl: 'https://api.objectstack.dev',
  content/docs/utilities/data-objectstack.mdx:364   baseUrl: 'https://api.objectstack.dev',

⭐ objectui#8128 已落地(⛔ 不要碰):
  :499  [ObjectStack Documentation](https://docs.objectstack.ai)
  :544  [ObjectStack Documentation](https://docs.objectstack.ai)

CONTROL 'objectstack.ai' 在该文件 3 处

⛔ 裁决 ① —— 用保留给文档的主机名,⛔ 不要换成 api.objectstack.ai

卡把这个决定留给了本席,并且它自己说清了为什么不猜:

api.objectstack.ai is a plausible substitution and that is exactly the problem — plausible is not established. Egress policy in the session blocks objectstack.ai, so I could not probe it.

本席也探不了(同一条出网策略)。⇒ ⛔ 一个本会话里无人能确立的主机名,不许写进一段读者会照抄的代码。

而卡的第二个选项才是对的那个,并且它有一条比"偏好"硬得多的依据:

an example baseUrl may be better off as an obviously-fake placeholder, since a real-looking host in a copyable snippet invites a reader to leave it in。

⇒ RFC 2606 / RFC 6761 保留 example.com 与 .invalid 这类名字,正是为了让文档能命名一个"永远不可能解析到别人真实服务"的主机。 用它们,读者忘了改也不会把流量指到任何真实的地方;而一个看起来像真的主机,忘了改就是静默的错误配置。

⇒ 选一个保留域(例如 https://objectstack.example.com 之类),并让紧邻的散文说明这是占位、请填自己的主机。⛔ 不要写任何真实存在或看起来真实的主机名。

⚠️⚠️ 裁决 ② —— 一个本席量出来、卡里没有的仪器陷阱

全仓其余所有 objectstack.dev 的命中,都不是域名:

content/docs/guide/ci-cd-pipeline.md:526          `objectstack dev` backend booted from …
packages/auth/src/__tests__/workspaceAdminPositions-5389.test.tsx:21   booted with `objectstack dev --seed-admin --fresh`

⇒ 它们是 CLI 命令 objectstack dev(中间是空格)。而正则里的 . 匹配任意字符 ⇒ 一次未锚定的 grep -rn 'objectstack.dev' 或 sed s/objectstack.dev/…/ 会改坏这两个无关文件。

⛔ 锚定那个点(objectstack\.dev),并且只动本卡点名的那两行。

⛔ 裁决 ③ —— 只动这两行

⛔ 不动 :499 / :544(objectui#8128 已落地的活)· ⛔ 不动该文件其它任何内容 · ⛔ 不动 content/docs/guide/ci-cd-pipeline.md 与 packages/auth/**(那是 CLI 命令,不是缺陷)。

验收 —— ⛔ 不许拿闸门当证据

卡量过并写死了原因:这两处在代码围栏里,而 Lychee 不从围栏里抽取链接 ⇒ 链接扫描永远不会点名它们。这不是 #8128 修得不全,是这个仪器根本看不见这一类。⇒ CI 两种情况下都绿。

三条读数:

• 主体:api.objectstack.dev 在该文件降到 0;
• ⭐ 亮对照 A:objectstack.ai 在该文件仍为 3(:499/:544 的两条散文链接加另一处)⇒ 证明探针在跑,而不是你把整个域名一律清了;
• ⭐ 亮对照 B(这条抓过度匹配):content/docs/guide/ci-cd-pipeline.md:526 与 packages/auth/src/__tests__/workspaceAdminPositions-5389.test.tsx:21 的 objectstack dev 原样未动。

⚠️ 亮对照 B 是唯一能抓住"正则吃掉了 CLI 命令"这个假修复的腿。 只看主体归零的验收会漏掉它。

⛔ 边界

• ⛔ 永不编辑 content/docs/releases/;本卡在 content/docs/utilities/。
• ⛔ 不改任何代码,不加闸门(围栏内的链接是 Lychee 的结构性盲区,补它是另一个题目)。
• 条款②:纯文档 ⇒ 预期 Clause-②: no,按细则同载 Contract-text: 引证;changeset 量了再说。
• ⛔ Worktree-first;⛔ 永不 git stash;⛔ 永不按名字杀进程;PR 开出后 ⛔ 不得再写 draft 标志。

⭐ 为什么这张 p3 值一个位置

失败模式是静默且延后的:读者照抄,配置指向一个不存在的域,而问题以运行时网络错误的形式出现 —— 既没有闸门会红,也没有任何东西把他指回这一页。⇒ 排查成本远高于这一行的修复成本。

Ruling 1 asked for a reserved-domain placeholder; the corpus had already decided WHICH one, which is a mechanism assumption I measured rather than assumed: the same file uses https://api.example.com at 11 other baseUrl sites (the first at :48) and the package's own PUBLISHED JSDoc @example in packages/data-objectstack/dist/index.d.ts already reads baseUrl: 'https://api.example.com' — so the two fixed lines were the only stragglers on the page, not a new convention being introduced. Ruling 2's anchored-dot discipline was followed literally: every replacement was an exact-literal full-line match with an asserted count of 2, no regex and no sed. Diff is 1 file, +8/-2.

(2) LIT CONTROL A — anchored 'grep -nP objectstack\\.ai' on the file = 2 occurrences at :505 and :550, both objectui#8128's landed prose links, byte-identical (line numbers +6 only because the new paragraph sits above them). CORRECTION TO THE BRIEF: the expected value 3 is an UNANCHORED reading — with a regex dot, the third hit is :551 'github.com/objectstack-ai/objectui/issues', where the dot matched the HYPHEN in the org name objectstack-ai. That is Ruling 2's own instrument trap landing on Ruling 2's control. Anchored truth is 2; the control is lit either way. (3) LIT CONTROL B — 'git grep -nP \"objectstack dev\" -- .' = 11 lines across 8 files, all unchanged, including both sites the brief named.

'git diff --stat 42df92809 HEAD' = 1 file changed, 8 insertions, 2 deletions, which is the proof none of the 11 moved.

EXTRACTION INVARIANCE (measured, not assumed, because the added paragraph is the only thing that could move the snippet gate's input): the gate's own exported scanFences() reports the same 15 blocks and 3 markers before and after, with the same fragmentReason/consumed state, and the only byte difference across the whole extracted program set is the two string literals. ESLINT: not owed, measured not narrowed — npx eslint on the file --format json returns 'File ignored because no matching configuration was supplied'. NOT MEASURED: nothing; no ablation applies (docs-only, no gate added).

    "noted, not filed: the CLI-command population the ruling warned about is wider than the two files it named — 11 lines across 8 files carry 'objectstack dev'. No defect; it only widens the blast radius an unanchored regex would have had. Successor: none.",

✅ 已落地 —— PR #8858 合并，main = 8a388ee76

按内容验证，⛔ 不按 sha，三条读数外加两盏对照灯：

SUBJECT   git grep -nP 'objectstack\.dev' origin/main -- .                                    → 无输出，exit 1（全仓，锚定）
          git grep -cP 'api\.example\.com' … data-objectstack.mdx                             → 14（合并前 11）
          git grep -c 'RFC 2606' … data-objectstack.mdx                                       → 1（占位符段落在位）
CONTROL A git grep -nP 'objectstack\.ai' … data-objectstack.mdx                               → :505 / :550，逐字未动
CONTROL B git grep -nP 'objectstack dev' origin/main -- . | wc -l                             → 11，与合并前逐字相等

两个 fence 的 baseUrl 现在指向 RFC 2606 保留的 api.example.com，并且新增的一段散文把为什么它永远不会解析写进了正文 —— 裁决 ① 要的是「保留给文档的主机」，不是随手换个字符串。

⭐ CONTROL B 是这一班标准里那种真正的对照：它守的是「用裸正则批改会怎样」，而一个不锚定的 objectstack.dev 正好会打到这 11 行、8 个文件。它有能力因为那个失败模式变红，所以它的「不变」是证据。

⛔ 存档：本卡的裁决 ② 自己踩了它禁止的那个陷阱

裁决 ② 要求「用锚定的点」，同时给了 CONTROL A 的期望值 3。合并后的树上锚定读数是 2。

第三个命中只在不锚定时出现：:551 的 github.com/objectstack-ai/objectui/issues，正则的 . 匹配到了组织名 objectstack-ai 里的连字符。⇒ 写下「必须锚定」这条规则的那次测量，自己用的是不锚定的读法。 dev 指出来了，本座位确认。这是这一班同一个陷阱的第三次（前两次都是 objectstack.dev 的 . 匹配 CLI 命令 objectstack dev 里的空格）。

另一条也存档：dev 的报告把「这个包既有的约定」记在 packages/data-objectstack/dist/index.d.ts 上。⚠️ dist/ 不在版本控制里，干净检出上不存在，那条引用不可复现。结论成立，载体应当是 packages/data-objectstack/src/index.ts:2657 —— 那段会被编译成 .d.ts 的 JSDoc @example。⇒ 新规矩：引用构建产物（dist/、node_modules/）的断言在干净检出上无法复核，把它挪到被追踪的载体上。

范围内没做、且是对的

• content/docs/guide/data-source.md:72 的 https://api.your-instance.com 分诊明确划在范围外，没有被顺手改。想统一整页集合是另一张卡。
• 新段落放在被改的第一个 fence 下面（:155）而不是 Quick Start 的第一个 baseUrl 例子（:48），以留在本卡点名的两个站点内。

⚠️ 给下一个改这个文件的人

本 PR 的 CI 全绿，但 ci.yml:183-195 的 "Decide whether this change needs a full run" 在 pull_request 上用 ':(exclude,glob)content/**' 排除了这个目录 —— ⇒ PR 页面上的 Test (shard N/4) 是跳过的，不是跑过的（10 秒 vs 合并队列里的真实运行）。绿色只证明 job 被派出去了，⛔ 不证明它看过你的改动。合并队列才是 main 之前最后一道校验。同批的 #8857 就是被队列抓到的。

关闭。
