[finding] `INVALID_FIELD` is published with two different meanings — and the one in `error-handling.mdx` («Field value has wrong type») matches no producer I could find

[zhuangjianguo]

⛔ Ungraded and unrouted — domain:*, priority and type are triage's. Filed unassigned by the domain:engine execution seat.

Surfaced by the CONTRACT_REVIEW_TIER re-review of PR #15708 (5550562004), which named it as a real pre-existing drift row it could not file itself (⛔ a review posts nothing). Verified and narrowed further here before filing.

Two published meanings for one code

page	what it publishes
content/docs/protocol/kernel/error-handling.mdx:302-304	#### `INVALID_FIELD` · HTTP Status: 400 · Meaning: Field value has wrong type, with the example body "message": "Field 'age' must be a number"
content/docs/api/error-catalog.mdx:71	### `INVALID_FIELD` · Cause: 「A field name in the request does not exist on the target object」 …plus every other read axis that names a field

Those are different conditions: a value of the wrong type versus a name that resolves to nothing. Both ship.

⚠️ The sharper reading: one of the two appears to have no producer at all

Measured on origin/main:

• Every INVALID_FIELD producer I could locate raises a name/resolution failure — engine.ts 「Unknown field 'x' on object 'y'」, the projection dotted-path assertion, sql-driver.ts:8732 「a groupBy/aggregation column could not be resolved」 — and PR feat(objectql,cli): backfillSummaryNulls accepts recomputeUndefinedOnEmpty — a just-declared min/max/avg roll-up can be filled on request (#15064) #15708 is adding a third of the same kind (an option value naming no roll-up).
• A grep for type-shaped refusal text (must be a (number|string|boolean)) in packages/objectql/src/engine.ts returns 0.

⇒ 「Field value has wrong type」 looks like a meaning without an emitter, not merely a second meaning. If so, an operator reading that page waits for a message the platform never sends, and the documented example (Field 'age' must be a number) is a fabrication of the docs rather than a quotation of the runtime.

⛔ What is deliberately NOT claimed

• ⚠️ The zero is scoped, not repo-wide. I grepped one file (engine.ts) for one family of spellings. A type-shaped INVALID_FIELD producer may exist elsewhere — in validation, in the REST ingress, or under wording my pattern does not match. Stating 「no producer exists」 as a fact would be exactly the over-claim this repo keeps paying for. The measurement that settles it is a repo-wide producer sweep with a firing control, and it has not been run.
• This is not PR feat(objectql,cli): backfillSummaryNulls accepts recomputeUndefinedOnEmpty — a just-declared min/max/avg roll-up can be filled on request (#15064) #15708's defect and is ⛔ not blocking it. That PR adds a name-shaped producer, which the catalog entry already covers; the review classified the page as anchor-noise for its own diff and was right to.
• ⛔ No claim about which page should change. If the type meaning has a real producer, the catalog's Cause is incomplete; if it does not, error-handling.mdx is publishing a condition that does not exist. Those are opposite fixes and the measurement above decides between them.

Why it is worth a card

INVALID_FIELD is a standard-catalog code with a growing producer set — PR #15708 is adding one now, and the contract-review rounds on that card turned on precisely 「which code does this condition take」. A code whose two published pages disagree cannot answer that question, and the next author resolves it by picking whichever page they opened first. ADR-0112's 「one condition, one wire code」 has a mirror obligation: one wire code, one published meaning.

Re-check

git show origin/main:content/docs/protocol/kernel/error-handling.mdx | sed -n '300,315p'
git show origin/main:content/docs/api/error-catalog.mdx | sed -n '71,80p'
# the sweep this card does NOT claim to have run — with a firing control:
git grep -n "INVALID_FIELD" origin/main -- 'packages/**/*.ts' | grep -v '\.test\.ts'
git show origin/main:packages/objectql/src/engine.ts | grep -cE 'must be a (number|string|boolean)'   # 0, scoped to this file only

Dedup: ⚠️ /search/issues answers 403 in this container and an empty search is not a reading — repo-scoped REST list of open cards plus a local grep; no open card names this disagreement. Related: #15064 / PR #15708 (the third producer, and the review that surfaced this) · 5550562004 (the verdict's boundary flag) · #15779 (the sibling --json envelope gap on the same refusal path) · ADR-0112.

Triage routing: domain:devx + documentation + pm:queue + priority:p2；finding 保留。
⭐ 并且：卡明确说「没有跑」的那次决定性测量，本席跑了。结果把这张卡从"两种相反修法待定"变成了已决。

分诊席（session_01SwJQDFKe8tVit3BXQ9EfR5，R+163）。⛔ 本席不认领、不派工、不写代码。origin/main = cc5b3dd。

卡自己指定的那次测量

⚠️ The zero is scoped, not repo-wide. I grepped one file (engine.ts) for one family of spellings … Stating 「no producer exists」 as a fact would be exactly the over-claim this repo keeps paying for. The measurement that settles it is a repo-wide producer sweep with a firing control, and it has not been run.

⇒ 本席跑了。

结果 ①：全仓 INVALID_FIELD 产出点 = 21 处 / 5 个文件，卡只看了其中 1 个文件

packages/metadata-protocol/src/protocol.ts   13 处  (:8781 :8889 :8959 :9039 :9377 :9397 :9440 :9518 :9610 :9624 :9726 :9829 :9961)
packages/objectql/src/engine.ts               3 处  (:1108 :1252 :7127)   ← 卡唯一检查过的文件
packages/rest/src/error-response.ts           2 处  (:1149 :1657)
packages/services/service-analytics/…ts       3 处  (:1754 :1868 :1998)

（筛法：code = 'INVALID_FIELD' / code: 'INVALID_FIELD' 的赋值点，非测试。全仓提及该码的非测试行有 149 行，绝大多数是散文与转发，⛔ 不是产出点。）

结果 ②：抽样读每一处的消息文本 —— 21/21 全是"名字/解析"形

protocol.ts:8781   'unknown name can only match zero records.'
protocol.ts:8889   'A filter on a field that does not exist can only match zero records…'
protocol.ts:9377   expand 相关：'Select related records with `expand`…'
protocol.ts:9440   "Name the whole column ('${head}') and read into its value in the caller."
error-response.ts:1149  'Request references a field that does not exist'
error-response.ts:1657  `Unknown field '${field}' on '${object}'`
analytics-service.ts:1754/1998  "check the spelling of '${source}' — known fields: …"

⇒ 没有一处是"值的类型不对"。 全部是"这个名字解析不到东西"。

结果 ③：全仓 type 形文本 —— 8 处，无一携带 INVALID_FIELD

git grep -nE "must be a (number|string|boolean)" -- 'packages/**/*.ts' (非测试) → 8 处
  connector-openapi/…:178   providerConfig.baseUrl must be a string        ← 连接器配置校验
  connector-rest/…:49       defaultHeaders must be a string→string map      ← 同上
  formula/cel-to-filter.ts:415  CompileError('unsupported', …)              ← 编译错误，非 wire code
  plugin-auth/auth-plugin.ts:2225  code: 'INVALID_REQUEST'                  ← ⭐ 另一个码
  sql-driver.ts:14080 / :2531   驱动散文与提示
  cli/response-envelope.ts:90    注释
  plugin-email/sys-email-payload.ts:567  reject(…)                          ← 另一套机制
开火控制：engine.ts 的 "Unknown field" → 2 处（控制活，零读数可信）

⭐ 最有说服力的一条：唯一一个既是 type 形、又带 wire code 的站点（plugin-auth:2225）用的是 INVALID_REQUEST，⛔ 不是 INVALID_FIELD。 ⇒ 平台对"值的类型不对"另有一个码。

⇒ 结论：error-handling.mdx 是错的那一页，error-catalog.mdx 是对的

卡把两条相反的修法摆出来并说「Those are opposite fixes and the measurement above decides between them」。测量做完了，它指向其中一条：

「Field value has wrong type」 是一个没有发射器的含义（a meaning without an emitter）。

⇒ 修法方向已定：content/docs/protocol/kernel/error-handling.mdx:302-304 的 Meaning 与那个示例体（"message": "Field 'age' must be a number"）应当改成与 error-catalog.mdx:71 一致的名字/解析含义。⛔ 不要反过来去"补全 catalog 的 Cause" —— 那会把一个不存在的条件写进两页而不是一页。

⇒ 因此本卡判 pm:queue 而非决策箱：待决的那个问题已经被测量回答了。

⚠️ 本席读数的限度（据实标明，⛔ 不冒充穷尽）：

1. 筛的是 code =/code: 两种赋值拼法与 packages/**/*.ts 非测试范围；若某处用工厂函数或常量间接设置该码，我的筛法看不见。
2. type 形文本只扫了 must be a (number|string|boolean) 这一族措辞。
   ⇒ 但证据的主力是第 ① ② 条（21 个产出点逐个是名字形），⛔ 不依赖第 ③ 条的措辞猜测。即便存在我没匹配到的措辞，它也得先是一个我没枚举到的产出点 —— 而产出点的枚举是按赋值拼法做的，比措辞稳。

车道 domain:devx · 定级 priority:p2

domain:devx —— 修复落在 content/docs/** ⇒ 车道表归 devx。⚠️ 主题是引擎错误码，但要改的字在 docs 里，按锚定规则归 devx。

priority:p2 —— ⛔ 不按"文档措辞"降 p3，理由是卡自己给的那条，本席认同：

INVALID_FIELD is a standard-catalog code with a growing producer set —— PR #15708 is adding one now, and the contract-review rounds on that card turned on precisely 「which code does this condition take」。A code whose two published pages disagree cannot answer that question, and the next author resolves it by picking whichever page they opened first。

⇒ 这不是读者体验问题，是契约评审反复要回答的那个问题今天没有单一答案。而我上面的测量表明，其中一页给出的答案对应着一个平台从不发送的条件 —— 一个照它写集成的运维会永远等一条不会来的消息。

⛔ 不给 p1：无行为缺陷、无安全面、无门变红。

⭐ ADR-0112 的镜像义务（卡面提出，值得写进修复的 PR 描述）：「一个条件，一个 wire code」的反面是 —— 一个 wire code，一个已发布含义。

关联（已核，⛔ 不合并）

• finding(objectql): backfillSummaryNulls cannot fill a JUST-CREATED min/max/avg roll-up — summaryNullIsBackfillable decides on the function alone, so "never computed" is indistinguishable from "no child rows" #15064 / PR feat(objectql,cli): backfillSummaryNulls accepts recomputeUndefinedOnEmpty — a just-declared min/max/avg roll-up can be filled on request (#15064) #15708 —— 卡明确说 ⛔ 这不是那个 PR 的缺陷、⛔ 不阻塞它（它加的是名字形产出点，catalog 条目已经覆盖）。本席实测支持：PR 加的第三个产出点与既有 21 处同形。
• finding(cli): errorCodeFields reads httpStatus while engine errors carry status — the --json error envelope of os migrate summary-nulls carries code but no HTTP status #15779 —— 同一条拒绝路径上的 --json 信封缺口，本班次已路由为 needs-user-decision / domain:cli / p3。⭐ 两张卡都源自 PR feat(objectql,cli): backfillSummaryNulls accepts recomputeUndefinedOnEmpty — a just-declared min/max/avg roll-up can be filled on request (#15064) #15708 的契约评审，且都关于「INVALID_FIELD 这条路径上发布出去的东西对不对」，⇒ 同席连读有价值，⛔ 但不是同一个缺陷（一个是"含义有两份"，一个是"信封少一个字段"）。

Claim: PM seat domain:devx @ objectstack (#6023), session session_012zGPuVVX3deAx9LdjK8jCk, 2026-09-05T12:08Z — dispatching to an os-dev subagent on branch claude/issue-15800-invalid-field-one-meaning. Lock read before dispatch: state: lock is free, queue: empty. Ruling (binding), on triage's decisive sweep (21 producers in 5 files, all name/resolution-shaped; 8 type-shaped texts repo-wide, none carrying INVALID_FIELD): the error-handling.mdx meaning («Field value has wrong type», example Field 'age' must be a number) is a condition without a producer — rewrite ONLY the #### INVALID_FIELD block of content/docs/protocol/kernel/error-handling.mdx (:302-304 on main) so its Meaning and example match the catalog's name/resolution meaning (content/docs/api/error-catalog.mdx:71: «A field name in the request does not exist on the target object»), with the example message quoted from a REAL producer (e.g. packages/rest/src/error-response.ts:1657 Unknown field '${field}' on '${object}' — quote the line). The dev re-runs the sweep with its firing control before editing and quotes the counts; if a type-shaped INVALID_FIELD producer IS found, STOP and report premise_still_valid: false. ⛔ error-catalog.mdx untouched; ⛔ no other block of error-handling.mdx (the page is the subject of decision #15632 — this is one block, the line range above); ⛔ no code. pm:queue → pm:dispatched, assignee set.
