[finding] the HTTP header blocks in error-handling.mdx teach X-RateLimit-* headers no producer sets, and a Retry-After on 503 that no 503 producer sets

Found while fixing #16937, which corrects the details bags in the same fences. That card's ruling is scoped to details members, so the adjacent HTTP header blocks were out of scope there and are filed here. Same page, same class, same failure direction: a copyable block a client is meant to read, where reading it yields nothing.

Measured on origin/main at fd5cff209f.

The claims

content/docs/protocol/kernel/error-handling.mdx carries three header blocks:

under #### RATE_LIMIT_EXCEEDED and again under ### Rate Limit Exceeded —
X-RateLimit-Limit: 1000, X-RateLimit-Remaining: 0, X-RateLimit-Reset: 1705412460
under #### SERVICE_UNAVAILABLE — Retry-After: 300

Readings, each with a positive control on the same corpus

reading	result	positive control on the same corpus
`X-RateLimit` anywhere in `packages/**`	1 hit, not a producer	`Retry-After` in `packages/**`: 142
any header-set of a ratelimit-named header (`res.header` / `setHeader` / `headers[...]`) tree-wide	0	same forms for `Retry-After`: 5
`Retry-After` within 10 lines of any 503 site (non-test, non-CHANGELOG)	0	identical technique on 429 sites: 2

Widening X-RateLimit from packages/** to the whole tree gives 31 hits, and every one is about GitHub's own API quota headers, not an ObjectStack response — they sit in scripts/pm/check-clause2-carriers.mjs and .github/workflows/docs-drift-check.yml. The single packages/** hit is a prose comment in packages/spec/src/integration/connector.test.ts:656 about upstream connector header names. No ObjectStack producer sets an X-RateLimit-* header on any response.

The Retry-After row is the more interesting one, because the header itself is real: both 429 producers set it —

packages/runtime/src/endpoint-policy.ts        headers: { 'Retry-After': String(retryAfterSec) }
packages/runtime/src/security/inbound-rate-limit.ts   res.header('Retry-After', String(retryAfterSec))

— so the control fires and the zero on the 503 side is a reading, not a dead grep. The five real 503 producers (packages/objectql/src/action-activation.ts:269, packages/triggers/trigger-api/src/api-trigger.ts:204, packages/plugins/plugin-auth/src/auth-plugin.ts:2260 and :2883) set no Retry-After and attach no details bag.

Consumer harm

A client written from the 429 header block paces itself on X-RateLimit-Remaining and reads null on every real 429 — so it does not pace at all, which is the opposite of what the block is teaching. The correct signal is on the wire and documented two lines below it: Retry-After, plus the retryAfterSeconds / resetAt pair that #16937 puts into the details fences.

A client written from the 503 block waits on a Retry-After that never arrives.

Why nothing catches it

Same gap #16937 and #17187 record on this page: these are prose fences, so neither the type-check nor any schema reaches them, and no gate compares a documented response header against the headers any producer sets.

Suggested fix

Drop the X-RateLimit-* lines from both 429 header blocks, keeping Retry-After, and drop the 503 header block. Alternatively, if the rate-limit headers are intended and simply unimplemented, this becomes a runtime card for the producers rather than a docs one.

Triage: finding admitted; lands in content/docs/protocol/kernel/error-handling.mdx; domain:spec; priority:p3.

Three header blocks teach X-RateLimit-* headers no producer sets, and a Retry-After on 503 that no 503 producer sets. Measured on origin/main fd5cff209f.

⇒ same failure direction as its sibling: a copyable block a client is meant to read, where reading it yields nothing. A client written against these headers gets undefined forever, and nothing anywhere reports it.

⭐ Fold with objectstack#17187 — the five gates are met

gate
① same defect shape and repair	✅ a documented wire artefact with no producer, on the same page
② same file / area	✅ `error-handling.mdx`, one changeset, one queue slot
③ every member graded	✅ both graded this round
④ each independently checkable	✅ headers vs the `QUOTA_EXCEEDED` `details` bag, separate probes
⑤ exclusion list named	see below

⇒ one dev takes #17187 and this card in one pass.

⛔ Excluded from the fold, named explicitly: #16937's details fences (already ruled and scoped — ⛔ do not re-open), and every other fence on the page whose producer shape is known. The family is exactly documented artefacts with no producer at all.

⚠️ As on #17187, the second-order question travels with it: a documented header no producer sets is either a docs defect or a missing producer. Measure which, per header, and say so — ⛔ do not delete a block that documents something we intended to send.

Size/model suggestion: M for the folded pair.

折叠五门,逐条答过

同缺陷形态同修法 —— 两张都是「页面上一段可复制块教了一个没有任何生产者的行为」,修法都是改散文。⛔ 不是「同关键词」或「同子系统」。
同包/区域 —— 同一个文件 content/docs/protocol/kernel/error-handling.mdx:一个 worktree、一个 changeset、一个队列位。
每张都已定级 —— 两张都是 domain:spec + priority:p3,⛔ 决策箱里一张都没有。
每张独立可核 —— [finding] error-handling.mdx teaches a QUOTA_EXCEEDED wire fence for a registered error code that NO producer emits #17187 的判据是 QUOTA_EXCEEDED 的生产者搜索;[finding] the HTTP header blocks in error-handling.mdx teach X-RateLimit-* headers no producer sets, and a Retry-After on 503 that no 503 producer sets #17188 的判据是 X-RateLimit-* 的生产者搜索。两个结论必须分别给出,⛔ 不许一个结论套两张。
排除清单(长得像这一族但不是):
- [finding] the 429 details fences in error-handling.mdx teach three members no producer emits, and omit the one it does #16937 —— 同一页、同几段 fence 的 details 袋,已修,其裁定范围只管「生产者形状已知」的 fence。⛔ 不要重修它改过的部分。
- [finding] realtime-protocol.mdx documents four WebSocket message types that WebSocketMessageType does not declare (auth, auth_success, auth_error, subscribed) #17184 的字段形状那一半 —— 另一页(realtime-protocol.mdx),而且那一页正被 PR docs(protocol): drop the five WebSocket message types WebSocketMessageType does not declare #17700 占着。⛔ 不碰。
- 这一页上任何有生产者的 fence ⇒ 不属本族,⛔ 不动。

Declared file face

content/docs/protocol/kernel/error-handling.mdx —— 仅此一个文件。

⭐ 面不相交实测(2026-09-11T15:55Z)。未合并占用中:ui/app.zod.ts + 其 pin 测试(PR #17697)· ai/agent.zod.ts + references/ai/agent.mdx(PR #17699)· protocol/kernel/realtime-protocol.mdx(PR #17700)。⚠️ 最后一个与你同目录不同文件,⛔ 别串。另有他人在飞的 PR #17500 占着 repeater/row-schema 区域。⛔ 需要其中任何一个就停手上报。

每张卡必须falsify 的前提(⛔ 锚点取自 `origin/main` 的当前状态,⛔ 不继承卡的读数 `fd5cff209f`)

#17187 —— QUOTA_EXCEEDED:该错误码已注册,但页面教的那段 wire fence 没有任何东西发出它。自己搜生产者。
#17188 —— X-RateLimit-* 头:页面的 HTTP header 块教了没有生产者设置的头。自己搜生产者。

⭐ 两者都必须配点亮控制项:用同一个探针搜一个确实有生产者的错误码 / 一个确实被设置的响应头,必须搜得到。一个对什么都搜不到的探针什么也证明不了。⚠️ 一次只测一个断言:某个头「没人设置」与某个码「没人发出」是两个独立读数。

⭐ 分叉 —— 只有一支是你的

(a) 页面错 —— 教了平台不做的事,改散文。这是你的。
(b) 平台缺实现 —— 那些码/头本该被发出。⛔ 不是你的:那是产品/协议决策,停手上报,⛔ 不要实现,⛔ 也不要写暗示「以后会有」的散文。
⚠️ 两张卡可能落在不同分支上 —— 分别判,分别说。

⛔ Commit message —— 今天为此赔掉两整轮

commit ⛔ 不带任何卡片 trailer:Part of / Part-of / Refs / Fixes / Closes / Resolves / 裸 #NNNNN 一律没有。按 #17606,已推送分支上这条红无法解除(squash 取 COMMIT_MESSAGES),所以推之前是唯一的机会。

⭐ 推前 grep,并分别数裸词干 —— grep -oiE | wc -l(⛔ 不用 grep -c),Fix / Close / Resolve 各自单独数,点亮控制项 Co-Authored-By → 1、Claude-Session → 1。⚠️ 子串陷阱今天出现三次:findClosestMatches 里的 Closes、fixture 里的 fix、a closed ten-member enum 里的 closed —— 三次都是在提交前被这条 grep 抓到的。
⚠️ 而且门禁不会替你兜底:实测 partOfRe 是 /\bPart of\s+#(\d+)\b/gi,要求空格 —— Part-of: #N 这种写法门禁漏过(exit 0)。⇒ 你自己那条 grep 才是这一格唯一的网。
然后两腿跑 scripts/check-partof-closing-keyword.mjs:你的 commit exit 0,一个已知坏的 exit 1。⭐ PR 正文也要审同样这些词。

trailer 对,model-free:

⭐ 仪器纪律

exit 0 / 清掉的控制项 / 绿色跑通,只有在仪器可能给出反向结果时才算读数。 每个 0 都要配点亮控制项。⚠️ grep -c 数行不数次 —— 用 grep -o | wc -l。⚠️ 句子可能跨行折断:压缩空白前,// 行注释要剥 //,/* */ 块要剥行首 * —— 我今天两种都踩过,一次读成误锚的 0。⚠️ 用 git ls-files 枚举并核对总数(今天一次 glob 静默少了 3 个顶层页)。⛔ 别用文件内容 grep 文件名。⛔ 在带 built dist/ 的树上做普查不可复现。⛔ 作废的跑要上报,不要静默重跑;前提拒绝不是红,且不总是 exit 3。

Gate declaration 与 PR 正文

门禁对它的定义是 "this PR puts a new key on a published payload" —— 改散文不加键。⚠️ PR 正文里也要有独立一行 - **Clause-②: no**,用 readClause2Line 验(⛔ 不用字符串等值;## Clause-② … 标题是 near-miss —— 我今天自己写出过三次)。

⚠️ changeset:按仓里自己的规则判,并写明你用的是哪条规则 + measurement(content/docs/** 不随任何已发布包出货 ⇒ skip-changeset;⛔ 两边都不许假设)。⛔ 永不碰 content/docs/releases/。散文 only。Draft PR;正文写 Part of #17187 和 Part of #17188 两行,⛔ 只写在正文。

(2a) X-RateLimit-*: premise HOLDS, fork (a), corrected here. Every literal occurrence of the three header names in non-doc source is a headers.get READ of GitHub's own quota headers in scripts/pm agent tooling; no ObjectStack producer SETS any of them, while the same probe lights Retry-After (18 non-test) and X-Environment-Id (17). The three lines are dropped from BOTH 429 blocks; Retry-After: 45 stays, because two producers really do set it (runtime/src/endpoint-policy.ts, runtime/src/security/inbound-rate-limit.ts) and it is the signal the adjacent retryAfterSeconds / resetAt details already name. (2b) 503 Retry-After: premise FALSIFIED -- block deliberately NOT touched. The card states no 503 producer sets Retry-After. One does: packages/plugins/plugin-hono-server/src/current-user-endpoints.ts:204 calls c.header('Retry-After', ...) on the 503 arm of resolveRequestContext (status defaults to 503; the module's own docblock reads \"cloud's KernelWarmingError is a 503 + Retry-After\"). I pulled that file at the card's OWN anchor fd5cff209f through the contents API: the site was already there, so the card's probe missed it -- the tree did not change under it. My own first probe missed it too and that run is reported as void. Narrower reading stated separately: the 503 envelope there is {error: 'environment_unavailable'}, so no response carrying the SERVICE_UNAVAILABLE code sets Retry-After -- but the block as written is an HTTP-level block and a 503 with Retry-After is a real wire shape here. Per triage (do not delete a block documenting something we do send) it is untouched and handed back.",

ABLATIONS on the edited file, committed-first, each proven on disk by a git hash-object change and restored with `git checkout HEAD -- PATH` under an absolute-path trap, verified by an empty `git diff HEAD`: (1) delete the QUOTA_EXCEEDED heading + status line -> gate STAYS GREEN; (2) QUOTA_EXCEEDED 429 to 503 -> STAYS GREEN; (3) lit control RATE_LIMIT_EXCEEDED 429 to 418 -> EXIT 1, naming the file and line. So the gate is live on this file but structurally blind to QUOTA_EXCEEDED -- my predicted direction was REVERSED and is reported as observed, not as predicted. DISCARDED RUNS: (a) first header probe required receiver res/reply/response/ctx.res/headers so `c.header(...)` never matched -- void, redone; (b) first ablation used an unquoted heredoc, the shell ate the backticks, the anchor count and hash-object guard caught the no-op -- void, redone quoted; (c) check:partof-closing-keyword invoked with only COMMIT_MESSAGES answered exit 2 NOT WIRED (a usage failure, not a verdict) -- discarded, rewired. COMMIT-MESSAGE GUARD: grepped before the commit existed with `grep -oiE | wc -l`, all seven card-trailer patterns 0, lit controls Co-Authored-By 1 and Claude-Session 1; then two-legged with PR_BODY + PR_COMMITS_FILE -- real commit EXIT 0, a commit carrying a relation trailer EXIT 1. PR body audited with the same grep (one deliberate survivor: the identifier resolveRequestContext, bound to no card number). Clause-2 validated with readClause2Line -> {kind: declared, value: no}, near-miss control correctly read as near-miss. CHANGESET: skip-changeset. Rule (pr-automation.yml changeset-check): the exemption means 'this PR declares no release of its own'. Measurement: 81 tracked package.json, 11 private, 70 published; the one edited path sits under none of those 70 package directories and files[] entries are package-relative, so no published package can ship it; no published package is rooted at the repo root.

X-RateLimit-* 那半 → 分叉 (a) 成立,已改。头名探针:X-RateLimit-Limit 1 / Remaining 8 / Reset 1 —— 每一处都是 headers.get(...) 在读 GitHub 自己的配额头(scripts/pm 的 agent 工具链),零处设置。点亮控制项:Retry-After 18、X-Environment-Id 17。兄弟仓 objectui 也是零设置,而且它的控制项在那个仓点得亮(Content-Type 269、Retry-After 6),所以那个零算数;cloud 没检出 ⇒ NOT MEASURED。

它自己也报了那个探针的缺陷:卡的「Retry-After 在任何 503 站点 10 行内」写法在同一 commit 上返回 0,而生产者就在 5 行外。

⚠️ 留下的小尾巴(它给了选项但没自作主张):那个 503 块挂在 SERVICE_UNAVAILABLE 标题下,而该生产者返回的是非信封体 {error:'environment_unavailable'},并不配这个码。移到通用 503 说明是更整洁的长期形状 —— ⛔ 超出散文 PR,留作后续。
