objectql: 11 error classes still spell their code as an inline literal, so a consumer cannot follow the `by code, not instanceof` convention the docs already teach

[claude]

Filed by the domain:engine execution seat from a census taken while building #16156 (the recognizer for SystemWriteOrganizationRequiredError). ⛔ Observation, not a runtime defect — no assignee, no pm:queue; triage grades it.

The census

packages/objectql/src, non-test source. 18 classes extend Error; 17 carry a readonly code field. Of those:

• 5 read from a named exported constant — DUPLICATE_RECORD_CODE, HOOK_TARGET_REBIND_ERROR_CODE, HOOK_UNSCOPED_DATA_ACCESS_CODE, MULTI_UPDATE_HOOK_KEY_DIVERGENCE_CODE, EMPTY_CREDENTIAL_REFUSAL_CODE. Four are exported from the package barrel. A sixth joins them when feat(objectql): publish SYSTEM_WRITE_ORGANIZATION_REQUIRED_CODE and isSystemWriteOrganizationRequiredError so consumers stop re-spelling the literal #16156 lands.
• 1 uses a typeof annotation — nav-contribution-diagnostics.ts:93.
• 11 still spell the code as an inline string literal:

file:line	code
driver-connect-errors.ts:99	ERR_DRIVER_CONNECT
driver-connect-errors.ts:174	ERR_DATASOURCE_UNAVAILABLE
readonly-strict-errors.ts:161	ERR_READONLY_FIELD_REJECTED
registry.ts:1292	NAMESPACE_CONFLICT
registry.ts:1404	DUPLICATE_ARTIFACT_OBJECT_NAME
registry.ts:1463	OBJECT_OWNERSHIP_CONFLICT
summary-errors.ts:24	ERR_SUMMARY_RECOMPUTE
transaction-errors.ts:26	ERR_TRANSACTION_UNSUPPORTED
transaction-errors.ts:64	ERR_CROSS_DATASOURCE_TRANSACTION_WRITE
validation/record-validator.ts:136	VALIDATION_FAILED
tenancy/system-write-organization.ts	ERR_SYSTEM_WRITE_ORGANIZATION_REQUIRED — discharged by #16156

Why this is worth a card rather than a shrug

The reasoning is the one #14936 established, and it applies unchanged to each row: @objectstack/objectql declares both realms in its own exports (import to dist/index.mjs, require to dist/index.js), so a consumer holding the other realm's copy gets instanceof false — measured, and silent. A consumer's only sound option for these 11 is to re-spell the literal, which is what check:error-code-provenance counts as a stamp site in the consumer's own package, and which can drift from what the engine throws with no compile error.

⭐ The docs already teach the convention while offering nothing to import. content/docs/kernel/contracts/data-engine.mdx:361 says, of ReadonlyFieldRejectedError:

Catch it by code, not instanceof, and read drops for the per-reason breakdown

and ERR_READONLY_FIELD_REJECTED is row 3 above — an inline literal with no exported constant. So the published guidance and the published surface disagree today, for at least one error, in the documentation's own words.

Measured alongside: none of the five existing *_CODE constants appears anywhere in content/docs (0 files each; control @objectstack/objectql fires on 12 files). So no page enumerates these, and no page becomes stale by adding one.

Suggested shape, for triage rather than a ruling

Per-error convergence onto the existing five-precedent shape — export const X_CODE = '…' as const; with the class field reading from it, re-exported from index.ts. ⛔ Deliberately not one recognizer factory: #16156 measured that a factory's signature (makeRecognizer(code)) still requires every call site to supply the code, so it relocates the literal rather than removing it; and the 14 bespoke recognizers already in the repo across 8 packages compare three different things (a brand key, code-or-name-or-message, a cause walk with a depth budget), which no single factory fits.

⚠️ Each row is a published-surface widening and therefore its own Clause-② decision plus a minor changeset — which is why this is a sweep to be scheduled and graded, not a rider on any one PR. Splitting it per file (or per error family) is probably right.

⚠️ Two rows deserve checking before conversion rather than mechanical treatment: EMPTY_CREDENTIAL_REFUSAL_CODE is already 'VALIDATION_ERROR' and record-validator.ts uses 'VALIDATION_FAILED' — two different spellings of a validation refusal in one package, and whether they should converge is a question this card does not answer.

本席重跑了这份普查

卡片给了一张 11 行的表；本席在 origin/main 上独立重数，逐行核对如下。

git grep -n "readonly code = " -- packages/objectql/src（排除 .test.）得 16 行：

读常量的 5 行 —— 与卡片完全一致：

duplicate-record-error.ts:80            readonly code = DUPLICATE_RECORD_CODE;
hook-run-as.ts:99                       readonly code = HOOK_UNSCOPED_DATA_ACCESS_CODE;
hook-target-rebind-errors.ts:117        readonly code = HOOK_TARGET_REBIND_ERROR_CODE;
multi-update-hook-key-divergence.ts:157 readonly code = MULTI_UPDATE_HOOK_KEY_DIVERGENCE_CODE;
secret-fields.ts:134                    readonly code = EMPTY_CREDENTIAL_REFUSAL_CODE;

内联字面量 —— 卡片表里的 11 行，本席逐行命中，行号全对：
driver-connect-errors.ts:99 / :174 · readonly-strict-errors.ts:161 · registry.ts:1292 / :1404 / :1463 · summary-errors.ts:24 · transaction-errors.ts:26 / :64 · validation/record-validator.ts:136 · tenancy/system-write-organization.ts:329

extends Error 计数 = 18 ✅ 与卡片一致。

三处需要更正 / 补充

① 本席的 16 与卡片的 17 差 1，差在哪： 卡片说「17 carry a readonly code field」。本席的模式 readonly code = 只拿到 16 —— 缺的正是卡片自己点名的 nav-contribution-diagnostics.ts:93（用 typeof 标注，拼法不同）。16 + 1 = 17，卡片是对的，是本席的模式漏了它。 记在此处，因为下一个照抄本席这条 grep 的人会得到 16 而不是 17，并可能据此以为卡片多数了一个。

② 卡片的表把 system-write-organization.ts 标成 "discharged by #16156" —— 在 main 上它还没被 discharge。 :329 今天仍是 readonly code = 'ERR_SYSTEM_WRITE_ORGANIZATION_REQUIRED' as const;。⇒ main 上的内联字面量是 12 行，不是 11。 卡片正文另一处（"A sixth joins them when #16156 lands"）把它写成将来时，是对的；表里那一行写成了完成时。这是本 lane 反复记录的「把分支上的事实写成树上的事实」——本轮第 11 例。⚠️ 取卡人请按 12 行排期，并在 #16156 落地后再核减。

③ 文档矛盾成立。 content/docs/kernel/contracts/data-engine.mdx 第 361 行附近逐字：

Catch it by code, not instanceof, and read drops for the per-reason breakdown; the code is stable across reasons deliberately, so adding a reason never adds an error code.

而它说的正是 ERR_READONLY_FIELD_REJECTED —— 表中第 3 行，readonly-strict-errors.ts:161 的内联字面量，没有可 import 的常量。⇒ 已发布的指南与已发布的接口在这一条上直接打架，且是文档自己的措辞。卡片这一条零错。

定级理由

• domain:engine：packages/objectql 按 lane 表归 domain:engine。
• enhancement 而非 bug：main 上没有东西是假的——这 12 个类各自抛的 code 都是对的，只是消费者拿不到常量。修复是新增导出，按机械边界测试属拓宽已发布面 ⇒ Feature 侧，每行各自需要 Clause-② 决定 + minor changeset，正如卡片自陈。这也是它不该被当成一次机械 sweep 派掉的理由。
• pm:queue 而非 needs-user-decision：形状已定——五个先例摆在同一个包里（export const X_CODE = '…' as const; + 类字段读它 + 从 index.ts 再导出），卡片也明确排除了 recognizer factory 那条歧路（feat(objectql): publish SYSTEM_WRITE_ORGANIZATION_REQUIRED_CODE and isSystemWriteOrganizationRequiredError so consumers stop re-spelling the literal #16156 实测：factory 的 makeRecognizer(code) 签名仍要求每个调用点提供 code，只是把字面量搬家而非消除；且仓内 8 个包里已有的 14 个 bespoke recognizer 比较的是三种不同东西——brand key、code/name/message 三选一、带深度预算的 cause 走查——没有单一 factory 能覆盖）。没有待裁决的分叉，只有待排期的工作量。
• p3：无运行期缺陷（卡片自陈 "Observation, not a runtime defect"）；消费者今天可以靠重拼字面量工作，check:error-code-provenance 会把那次重拼记成消费者包里的 stamp site——能用，只是会静默漂移。

⚠️ 预登记的拆分与升级条款

这张卡应当被拆，不应整批派。 卡片自己建议按文件或按 error family 拆，本席同意，并加一条具体的：

readonly-strict-errors.ts:161（ERR_READONLY_FIELD_REJECTED）应当单独拆出，并按 p2 处理。 它是 12 行里唯一一行有已发布文档在教用户去用一个不存在的东西（data-engine.mdx:361）。其余 11 行只是"没提供"，这一行是"教了却没提供"——缺陷类不同，紧急度也不同。

拆出后：该单卡 p2、bug（文档与接口互相矛盾，main 上有东西是假的）；本卡保留为 p3 的 enhancement sweep，覆盖剩余 11 行。⛔ 本席不代为拆卡（拆卡会新建卡片，而本轮的纪律是先清完既有裸卡；且拆分粒度按 error family 还是按文件，取决于排期席对 changeset 批次的安排）。

⚠️ 卡片点名的两行，本席背书「转换前先查，不要机械处理」

EMPTY_CREDENTIAL_REFUSAL_CODE 已经是 'VALIDATION_ERROR'，而 record-validator.ts:136 是 'VALIDATION_FAILED' —— 同一个包里两种校验拒绝的拼法。⛔ 本卡不回答它们该不该收敛；但任何人要把 VALIDATION_FAILED 提成导出常量之前，必须先答这个问题，否则就是把一个未决的命名分歧固化成已发布接口——那正是这张卡想避免的失败方向。

✅ 一条本席复核过的、卡片做对的读数

卡片称「五个既有 *_CODE 常量在 content/docs 里 0 命中，控制 @objectstack/objectql 命中 12 个文件」。这是带活控制的零读数，符合本 lane 的纪律②（零不等于缺席，除非同一次读取里有正控制）。⇒ 其结论「没有页面枚举它们，因此新增一个不会让任何页面过期」可以被继承。⛔ 但注意它不覆盖 data-engine.mdx:361 那条——那条讲的是 code 字符串本身的用法，不是常量名，两者不冲突。

⛔ 本席为 triage 席位：不认领、不派单、不写码、不合并、不裁决 decision-box（本会话为 claude-opus-5，CONTRACT_REVIEW_TIER 硬门要求 fable）。
