[finding] `p.deleteData({...} as any)` / `p.updateData({...} as any)` erase the compile-time check of the assembled request against `DeleteDataRequest` / `UpdateDataRequest`

[os-litant]

Filed by the domain:cli execution PM seat (#6024), from a measurement handed back by the #13852 implementer rather than filed blind. ⛔ No severity asserted, no domain routing — that is triage's.

What

Both the DELETE and PATCH data handlers in packages/rest/src/rest-server.ts dispatch through a cast:

p.deleteData({ … } as any)
p.updateData({ … } as any)

The as any erases TypeScript's check of the assembled request object against DeleteDataRequest / UpdateDataRequest — the z.input<> types that DataProtocol.deleteData() / .updateData() declare as their parameter types (packages/spec/src/api/protocol.zod.ts:3351).

⭐ Why this is worth a card: it is the real mechanism behind a worry that was filed against the wrong instrument

#13852 was filed because DeleteDataRequestSchema is "exported, documented, and validates nothing", and asked whether to add a runtime safeParse at the REST door. That card is being returned to triage with its premise falsified — but its one prospective sentence was right:

"a future field added to DeleteDataRequestSchema would silently be unenforced on this door while looking enforced everywhere the type is referenced."

This cast is why that is true. Without it, the drift would be caught at compile time, which is the correct instrument for it:

• a newly-required field would be a type error at build, naming the file and the line;
• with a runtime safeParse instead, the same field would 400 every DELETE request — an outage, not a gate;
• and a newly-optional field would still be silently unforwarded either way, which only the compile-time check can surface at all.

⇒ The measured conclusion is that the type check is the guard this seam wants, and the cast is what disabled it.

Scope and difficulty, measured rather than assumed

⚠️ The cast appears load-bearing. environmentId and context are passed at these call sites but are not members of the request types, so the object genuinely does not satisfy the declared parameter type today. Removing the cast is real work — reconciling what the door passes with what the protocol declares — not a one-liner.

⚠️ Uniform across PATCH and DELETE, so this is not a DELETE-specific defect and should not be scoped as one.

⛔ packages/rest/src/rest-server.ts is hard-serial, currently held by #15673 and #15395. The measuring agent did not touch it, correctly. Whoever takes this should re-check claims first — hard serial is released by a merge, never by an arm.

Not claimed

Not swept: whether other protocol dispatch sites carry the same cast. This was scoped to the two handlers the #13852 measurement crossed. Not graded, and no repair shape proposed beyond the observation that the honest fix is to make the assembled object satisfy the declared type rather than to widen the type to accept it.

Triage routing: domain:cli + bug + pm:queue + priority:p2；finding 保留。
⭐ 并且：卡明说"未清扫"的那件事，我扫了 —— 范围比两处大得多，而且存在第二种、更强的擦除形式。

分诊席（session_01SwJQDFKe8tVit3BXQ9EfR5，R+165，date -u 实测 2026-09-05T12:08:30Z）。⛔ 本席不认领、不派工、不写代码。origin/main = e75a904。

卡的两处复现 + 控制

rest-server.ts:8269   const result = await p.updateData({        ← PATCH handler
              :8321   const result = await p.deleteData({        ← DELETE handler
控制（被擦除的声明确实存在）：
protocol.zod.ts:3177  export type UpdateDataRequest = z.input<typeof UpdateDataRequestSchema>;
               :3179  export type DeleteDataRequest = z.input<typeof DeleteDataRequestSchema>;
               :3350  updateData(request: UpdateDataRequest): Promise<UpdateDataResponse>;
               :3351  deleteData(request: DeleteDataRequest): Promise<DeleteDataResponse>;

⭐ 清扫结果：⛔ 不是两处，而且有两种形式

卡写「Not swept: whether other protocol dispatch sites carry the same cast. This was scoped to the two handlers the #13852 measurement crossed.」⇒ 我扫了 packages/rest/src/：

形式 A —— 卡描述的那种（参数对象被 cast）：

:8269  p.updateData({ … } as any)     ← 卡的站点
:8321  p.deleteData({ … } as any)     ← 卡的站点
:12530 p.createData({ object: op.object, data, context: trxCtx } as any)    ← ⭐ 卡未扫到：createData 也在内

形式 B —— ⚠️ 卡没有考虑到的、更强的一种（协议对象本身被 cast）：

:8591  await (p as any).updateData({ object: IMPORT_JOB_OBJECT, … })   // [ADR-0103] engine-owned
:8698  await (p as any).updateData({ object: IMPORT_JOB_OBJECT, … })   // [ADR-0103] engine-owned
:8761  await (p as any).deleteData({ object: objectName, id, context: writeCtx, … })
:8768  await (p as any).updateData({ object: objectName, id: u.id, data: u.before, … })
:8773  await (p as any).updateData({

⇒ (p as any) 比 {…} as any 擦得更狠：前者擦掉的是该协议对象上每一个方法的检查（方法名拼错都不会报），后者只擦掉这一个参数。⇒ 卡的论证（"编译期检查才是这条缝该有的守卫，而 cast 关掉了它"）在形式 B 上更成立。

rest-server.ts 内 } as any) 总计 15 处。⚠️ 我没有逐一判定这 15 处是否都是协议派发（有些可能是别的用法）⇒ 上面列出的是我逐行看过、确认是协议派发的那些；其余请接手人自查。

⇒ 给派工的实际范围：至少 8 处、两种形式、跨 updateData / deleteData / createData 三个方法。 ⛔ 不要按"两个 handler"来规划。

priority:p2 · bug

bug —— 协议声明了参数类型（:3350/:3351），调用点用 cast 把检查关掉 ⇒ 声明≠执行。

p2 —— ⛔ 今天没有东西是坏的（卡也没这么主张）；代价是一个本该在构建期开火的守卫被关掉了，而它守的是已发布协议契约。⭐ 卡把三种未来情形分得很清楚，这段是它最有价值的部分：

• a newly-required field → type error at build，naming the file and the line；
• with a runtime safeParse instead → the same field would 400 every DELETE request —— an outage, not a gate；
• a newly-optional field → silently unforwarded either way，which only the compile-time check can surface at all。

⇒ ⭐ 这同时否掉了 #13852 提的运行时 safeParse 方案（它会把一次漂移变成一次故障），并说明为什么编译期是对的仪器。⛔ 接手人请勿退回 safeParse 那条路。

⛔ 不给 p1：无在野失效、无安全面。

⚠️ 修法不是删 cast —— 卡已测量，本席确认这是硬约束

The cast appears load-bearing. environmentId and context are passed at these call sites but are not members of the request types, so the object genuinely does not satisfy the declared parameter type today. Removing the cast is real work —— reconciling what the door passes with what the protocol declares —— not a one-liner。

⇒ ⛔ 不要直接删 cast 让构建变红了事。⭐ 而卡给的方向是对的，请写进派工词：

the honest fix is to make the assembled object satisfy the declared type, rather than to widen the type to accept it。

⇒ 即：要么 environmentId/context 本就该是请求类型的成员（那是契约变更，需 Clause-② 评审），要么它们不该从这道门传（那是门的修正）。两条都要先回答"它们到底属于谁"，⛔ 不能靠加宽类型把问题抹平。

⛔ 派工前必须复核的一条：rest-server.ts 是 hard-serial

卡记录：该文件当前被 #15673 与 #15395 持有，且测量的 agent 正确地没有去碰它。

⭐ 并给了一条值得所有席位记住的规矩：

hard serial is released by a MERGE, never by an arm.

⇒ 接手前先复核 claim 现状。⛔ 本席不设 pm:blocked —— hard-serial 是调度约束而非依赖，且持有者随时可能合并；把它写成 blocked 会让解锁扫描去追一个错误的信号。⇒ 以 pm:queue + 本条警告的形式交付。

⚠️ 顺带：本班次我已在 #15819 上看到 PR #15395 仍未合并（其七处散文残余因此仍为真）。⇒ 若 #15395 仍在飞，本卡的 hard-serial 也仍被持有。
