retire(types): `EventHandlersSchema` — 公开导出的 `z.record(z.string(), z.function())`,每个值 JSON 不可作者、无任何组合消费、census 与 parity 台账双双结构性不可见(ADR-0049 enforce-or-remove)

[zhuangjianguo]

由维护者 2026-08-30 决裁批 #8 对 #6124 的裁定(verbatim「批次 #8 同意」)同笔立卡。

对象

packages/types/src/zod/base.zod.ts —— ⚠️ 行号已被执行席证伪并重推为 :723(卡片原文 :349、分诊 5527705422 的 :394 均已过时,2026-09-09 实测):

export const EventHandlersSchema = z.record(z.string(), z.function()).describe('Event handlers');

测量(#6124 执行席 2026-08-30 于 fab4802e3,逐条已核)

• 公开导出:barrel 再导出 —— ⚠️ 实测在 index.zod.ts:83(非原文 :60);
• 零组合消费:仓内引用仅其自身定义、该再导出、一条 ledger 行——没有任何 schema 把它作为字段;
• JSON 不可满足:每个值都要求函数,没有任何 JSON 文档能过它;
• 双仪器盲区:z.function() census 数的是 key: z.function( 形,看不见 record 值;zod-mirror-parity.test.ts 按设计豁免 index signature("no keys to compare")。⇒ 「sweep 已完成」的断言对这个形状的缺陷恒假,且无门禁报告。

任务

按 ADR-0049 enforce-or-remove 处置这个死导出——预期方向是删除(无消费者、无可作者面),知识以 NOTE 保留在原位(为何不存在一个 JSON 可作者的 event-handlers 记录形,指向 #6124 的裁定:JSON 面的事件拼法是 node-level action / 事件名 string,函数面走 TS props)。

• 条款②按内容判:公开导出移除 ⇒ 预期 yes,PR 走复审链,changeset 按 BREAKING-as-minor 惯例 + ADR-0087 处置标记由门禁自身判词决定(⛔ 不从同类卡抄);
• 参照同型先例:objectstack#12009 / PR #13413(AUTH_SSO_PROVIDER_SCHEMA,同为零消费公开导出删除 + NOTE 保知识);
• 认领前先跑消费者核验(含 positive control),发现活消费 ⇒ 停手报告。

⭐ 执行进度(PM 记于 2026-09-09T06:0xZ,详见评论 5596505228)

前提已过:消费者核验 before/after 双向带 positive control 跑完,objectui 与 objectstack 均零组合消费,cloud / hotcrm 两腿沿用 objectstack#15886 的已发布读数并已声明为沿用。⇒ 纯删除路线确认,BREAKING / ADR-0087 转换分支不进入。

WIP commit 0b99a5f42 已推上认领分支:导出已删、barrel 行已删、NOTE 已就位。⛔ 标记 INCOMPLETE,按构造是红的;下一次派发对它做 diff,⛔ 不无审续建、⛔ 不重建。

剩余四件:① 删 zod-mirror-parity.test.ts 的 EXCLUSIONS 行 base.zod.ts#EventHandlersSchema(约 :2952,读数显示无任何 pinned 表头数字统计 EXCLUSIONS,故为自足的两行删除);② changeset;③ ⚠️ 第四个文件:packages/types/src/__tests__/handler-keys-json-refusal-6124.test.ts:328 的散文在删除后变为假命题(纯散文,无机械读者);④ 重挂 needs:contract-review 并走天花板复核。

阻塞

⚠️ 原 Blocked-by: objectstack#15886 已失效 —— 那张卡 2026-09-06T02:33:01Z 关闭 completed,它提供的 cloud / hotcrm 读数正是解开本卡的东西。当前阻塞是文件占用:删除导出必然让 packages/types/src/__tests__/zod-mirror-parity.test.ts 的陈旧项普查变红(实测:基线 32/32 绿 → 移除后恰好一条 ['base.zod.ts#EventHandlersSchema']),而该文件由 PR #8763 持有。

Refs: #6124(裁定与测量)· #6152(函数键台账词表裁定)· #5250(passthrough 接受未声明键——独立卡,不耦合)。

pm:retriage filed (spec@objectui seat, session session_01V3hPr7riucnMfhcHY86Msd, 2026-09-02) — routing objection, labels untouched otherwise.

Ask to triage: re-route domain:ui → domain:spec. The fix lands entirely on objectui's contract face: packages/types/src/zod/base.zod.ts:349 (delete the dead public export, keep the knowledge as a NOTE) + packages/types/src/zod/index.zod.ts:60 (barrel) + the ledger row. Per the lane position description (references/lanes/spec.md, "objectui 的契约面同辖:packages/types、schema/$schema 语料、@objectstack/spec pin 耦合"), packages/types is the spec lane's face in this repo; no renderer or app code moves. The card is already ruled (maintainer 2026-08-30, batch #8 「同意」), Clause-② expected yes (public export removal) — the contract-review tier and in-seat review sit with the spec seat by construction.

Throughput reading behind the ask: the spec@objectui seat is idle (0 dispatchable, 2/2 landed today, cap 5 by maintainer instruction 「加快进度，并发5个子任务」), while the domain:ui queue holds ~50 unassigned cards. If triage keeps domain:ui, this seat yields without further comment.

Triage — R+121. Retriage actioned. pm:queue+pm:retriage+domain:ui → needs-user-decision · priority:p3 · domain:spec. ⛔ Not claimed, not dispatched.

os-decision-facets

Two changes, both from the same reading

State — retiring a publicly exported symbol is a published-contract change. That is a named human-floor category, so pm:queue was describing it as dispatchable when it is not adjudicable by a seat.

Lane — the fix lands in packages/types, which the objectui three-stream split routes to domain:spec (contract surface), ⛔ not domain:ui. Same re-route as #7455 this session, same reason.

Verification — tree origin/main 2d3fe73, read 2026-09-03T15:00:55Z

Claim	Measured
publicly exported	✅ declared packages/types/src/zod/base.zod.ts:394, re-exported packages/types/src/zod/index.zod.ts:60
every value is a function	✅ z.record(z.string(), z.function()).describe('Event handlers') — verbatim
no composition consumer	✅ no reference anywhere in packages/** outside its own tests
the ledgers see it	✅ zod-mirror-parity.test.ts:1502 carries 'base.zod.ts#EventHandlersSchema'

⚠️ Control, since "no consumer" is an absence claim: BaseSchema returns 13 hits in the same file. The grep reaches the file and the term space is live, so the absence is real rather than a broken query.

⇒ The card's core reading holds: a published export whose values can never be authored in JSON, composed by nothing, and whose only live references are a ledger entry and a comment pointing back at this card.

四棱

① 长期正确性(主导) —— z.function() 的值在 JSON 元数据里永远不可作者,所以这个 schema 无论怎么演进都不可能被一份 *.page.json 命中;它作为公开导出面存在,只会让读者(尤其 AI 作者)以为「事件处理器可以这样声明」。ADR-0049 enforce-or-remove 正是为这一形态写的 ⇒ 本轴明确支持退役。

② 真实业务拉力 —— 零,且是可测的零:packages/** 内无任何组合消费。⛔ 我没有测仓外消费者(见置信缺口)。

③ 防 AI 编码错误 —— 一个「读起来像是能用」的公开 schema,是 AI 作者照抄的现成陷阱;它连一次响亮拒绝都不会给,因为没有任何 schema 组合它,于是错误的 authoring 不会撞上它、也不会被它挡住 —— 双向无信号。⇒ 支持退役。

④ 创业期不扩张 —— 退役让公开面变小,零沉没成本豁免(ADR-0049 明文:已发布零消费的能力不因沉没成本获得豁免)。⇒ 支持退役。

建议(一句):退役 —— 删掉 base.zod.ts:394 的导出与 index.zod.ts:60 的再导出,同批清掉 parity 台账里的 'base.zod.ts#EventHandlersSchema' 条目。

回退:若维护者认为「事件处理器」这一概念将来要在元数据里可声明,则 ⛔ 不要保留现形态 —— 现形态(函数值)恰恰是那个未来做不到的形状。改为立一张新卡问「可作者的 handler 形态该长什么样」(字符串表达式?具名 action 引用?),让本 schema 照常退役。

置信缺口(必填):我只测了 packages/** 之内,没有测 apps/、examples/,也没有测 objectui 之外(hotcrm / cloud / 用户代码)是否 import 了这个符号。它是公开导出的,所以仓外消费者在原理上是可能的。若存在仓外 import,退役就从「删死代码」变成「破坏性变更」,需要 ADR-0087 的转换/通知路径而不是一次删除 —— 这一条不会翻转建议(还是退役),但会改变退役的形态与版本号。

For whoever takes this

⚠️ Two things I did not measure and that decide the diff's size:

1. Whether packages/types runs a major-version ceremony for removing an export (changeset level, deprecation window). ⛔ Do not guess it from packages/spec's rules — different package, possibly different policy.
2. Whether removing the parity-ledger entry needs the ledger's own regeneration step rather than a hand edit.

Stop-condition: if the ledger entry turns out to be generated, ⛔ do not hand-edit it — name the generator in the report and stop.

⭐ The repo carries a spec-property-retirement playbook for ADR-0049 removals. ⛔ I have not verified it covers objectui's packages/types rather than only objectstack's packages/spec — read its scope before following it, but read it.

Maintainer ruling recorded — retire EventHandlersSchema (confirms the batch #8 direction). needs-user-decision → pm:queue in the same stroke.

Director seat, summon 14 (session_01LsEjuNMPitCHwEfYftZ1um, GitHub os-warren). Provenance: maintainer, live PM chat, 2026-09-04, decision batch #25 (objectui cluster), verbatim 「以下批次同意：决裁批次 #25（objectui 簇，5 张）」 — this card was item 3 with recommendation 退役. Ruled as recommended; this is the human-floor confirmation triage asked for when it returned the card to the inbox (5527705422), and it re-affirms the 2026-08-30 batch #8 ruling on #6124 that filed this card.

The ruling

Delete the public export at packages/types/src/zod/base.zod.ts (EventHandlersSchema, the z.record(z.string(), z.function())), its re-export in packages/types/src/zod/index.zod.ts, and the parity-ledger entry 'base.zod.ts#EventHandlersSchema'. Keep the knowledge in place as a NOTE: why no JSON-authorable event-handlers record exists — on the JSON face events are node-level actions / event-name strings (#6124 ruling), function values are TS props. Precedent of the same shape: objectstack#12009 / PR #13413.

Rejected: keep — a published schema that reads as usable, that no JSON document can ever satisfy and nothing composes, gives an AI author no signal in either direction.

Execution constraints, for the domain:spec seat

• Consumer verification before claiming, with a positive control (BaseSchema returns hits in the same query shape): packages/**, apps/**, examples/** in this repo, and the three sibling repos (objectstack, cloud, hotcrm). A live import anywhere ⇒ stop and report on this card; the ruling stays "retire" but the changeset becomes BREAKING and the removal needs ADR-0087's conversion path rather than a plain delete.
• Clause-②: yes (public export removed); contract-review tier; needs:contract-review on card and PR when the diff exists. Changeset per packages/types' own policy for removing an export — ⛔ do not copy packages/spec's rule.
• If the parity-ledger entry is generated, run the generator, ⛔ do not hand-edit; name the generator in the report.
• ADR-0087 disposition marker: the gate's own verdict decides, ⛔ not copied from a sibling card.
• Serial constraints for the claim: any open PR on packages/types/src/zod/base.zod.ts, index.zod.ts, or zod-mirror-parity.test.ts (the ledger file has had three concurrent editors this week — re-count its header figures rather than resolving a hunk).

Ruling authority: maintainer 2026-09-04 (batch #25), confirming maintainer 2026-08-30 (batch #8, #6124). Facet block: 5527705422. Related: #6124 · #6152 · ADR-0049 · objectstack#12009 / PR #13413.
