Upload links: refuse at issue a field whose readonlyWhen holds now (carries the issue-time readonlyWhen half of #32734)

domain:server#4 · os-sales · session_01L6bhgWRcTEB3toGxnWvuvX

Carries the issue-time readonlyWhen half of #32734's first expected item; #32734 keeps the record-lock and static readonly refusal at issue, the consume-side refusal and the page text.

Filing category: ① product defect (in-flight split, references/execution-duties.md in-scope sub-issue; priority inherited).

Blocked-by: #32734

Business reason

An agent asked to attach an invoice to an approved expense claim (a field read-only by readonlyWhen) still hands out an upload link. After #32734 the page refuses with the reason and keeps no file, but the person only learns it after picking and sending the file.

What is missing

create_upload_link cannot judge readonlyWhen at issue without writing: the engine's update preview (engine.validate, ValidateDataResponse) documents that it does not run readonlyWhen, and getRecordFieldAccess excludes conditional read-only and the approval lock. No write-free readonlyWhen judgement is exported.
Measured by the Upload links: a link is issued for a record the user cannot change, and the upload page then says "Done. The file was attached" when nothing was attached (readonlyWhen), or "Upload failed" with no reason (approval lock, 500) #32734 card thread at d728d73; re-check: grep -n "readonlyWhen" packages/objectql/src/engine.ts packages/spec/src/**/validate*.ts.

Expected

One write-free judgement of "is this field writable on this record now" that runs readonlyWhen (the engine's own, ⛔ no second CEL evaluation in service-storage or packages/mcp), and create_upload_link refuses with the same reason update_record gives.
If the fix changes the update preview's documented limit, that is the engine contract's text: the claimer reads it first and states whether it widens a published surface (Clause-②).

Reader who acts: the domain:server engine face (packages/objectql validate preview), then packages/mcp create_upload_link.
Dedupe: parent #32734; repo:objectstack-ai/objectstack is:issue validate preview readonlyWhen → 37 hits, the only open ones this card and a seat post (#18549); none on this.

Unblocked · 2026-11-12T18:31Z: Blocked-by: #32734 closed by PR #32779 (merged 9af0766). Back to pm:queue. Same area:files door as #32754 (claimed by domain:server#4): serial behind it, then #32783.

Re-grade on the maintainer's instruction: priority:p1 → priority:p0. State unchanged (pm:queue, unassigned). Written by a test session, not a seat.

Whose instruction: the maintainer, in an MCP capability-test session (Claude Code), 2026-11-13.
Verbatim: 「把 [Decision] How should an MCP agent create a record whose required file field must be filled (e.g. an expense line with a required e-invoice)? #32686 也提到 P0 .这些也都开始处理.这样我们审批相关的MCP就非常好用了.」, said about the MCP upload and approval cards listed together: [Decision] How should an MCP agent create a record whose required file field must be filled (e.g. an expense line with a required e-invoice)? #32686, storage + mcp: one upload link on a multiple: true file field accepts several files (same user, record, field, one use, same expiry) — ruled A #32747, console AI chat: an uploaded image/PDF goes to the model and the agent puts that same file into the record's file field, as the user — ruled A #32749, Upload links: refuse at issue a field whose readonlyWhen holds now (carries the issue-time readonlyWhen half of #32734) #32768.
Serial order kept: this card is on the same area:files door as Attachments: a member cannot attach a file to their own record (create_upload_link attachments:true answers 403 "cannot create sys_attachment"), though they can edit the record #32754 (p0, dispatched to domain:server#4), so it still follows Attachments: a member cannot attach a file to their own record (create_upload_link attachments:true answers 403 "cannot create sys_attachment"), though they can edit the record #32754 there. [Decision] How should an MCP agent create a record whose required file field must be filled (e.g. an expense line with a required e-invoice)? #32686 now also touches the upload-link door at p0, and the lane orders the two.
Identity: this session has no fleet App credentials, so this write goes through the user account. Nothing is claimed here.

⛔ Not a claim; the claim and state are unchanged, and the work continues.

Maintainer, verbatim (triage#1 session): 「6张MCP卡（[Decision] How should an MCP agent create a record whose required file field must be filled (e.g. an expense line with a required e-invoice)? #32686、Upload links: refuse at issue a field whose readonlyWhen holds now (carries the issue-time readonlyWhen half of #32734) #32768、console AI chat: an uploaded image/PDF goes to the model and the agent puts that same file into the record's file field, as the user — ruled A #32749、storage + mcp: one upload link on a multiple: true file field accepts several files (same user, record, field, one use, same expiry) — ruled A #32747、[Decision] Should an approver be able to see and decide their pending approvals over MCP? #32442、MCP: a submitter's agent cannot recall or resubmit its own approval request — approval_recall / approval_resubmit are not ai.exposed, while the approver's four decide actions now are (ruling A on #32442) #32993）被 os-bob 测试会话一次性升为 p0，这些不阻塞发版」.
In this fleet p0 marks main or merge-queue red and the release window's blockers (「阻塞卡升 p0」). These six cards are MCP approval and upload capability work, not 18.4.0 regressions, so they carry p1: the highest working grade, first in their lanes after the blockers. That keeps the intent of the 07:27Z regrade (「…这些也都开始处理.这样我们审批相关的MCP就非常好用了.」) without holding the cut.
Order inside the family is unchanged: [Decision] How should an MCP agent create a record whose required file field must be filled (e.g. an expense line with a required e-invoice)? #32686 (upload before the record exists) → storage + mcp: one upload link on a multiple: true file field accepts several files (same user, record, field, one use, same expiry) — ruled A #32747 (several files per link) → console AI chat: an uploaded image/PDF goes to the model and the agent puts that same file into the record's file field, as the user — ruled A #32749 (the console chat attach step), with [Decision] Should an approver be able to see and decide their pending approvals over MCP? #32442 and MCP: a submitter's agent cannot recall or resubmit its own approval request — approval_recall / approval_resubmit are not ai.exposed, while the approver's four decide actions now are (ruling A on #32442) #32993 on the approval side and Upload links: refuse at issue a field whose readonlyWhen holds now (carries the issue-time readonlyWhen half of #32734) #32768 on upload-link refusals.

⛔ Not a claim; the claim (if any) is unchanged.

Line: agents over MCP attaching files · create_upload_link · common · measured
Why: Maintainer-set: os-bob relabelled p1→p0 on the maintainer's verbatim instruction (2026-11-13) for the MCP upload cards; grade kept.
Rule: the card was filed already carrying a grade and state and had no triage audit; this is that audit, under the adopted grading rules (pm-dispatch(grading) + NORTH-STAR: grade in a fixed order — impact, reach discount, one raise, release window — with decidable tests for security boundary, core task, workaround and "a real user can hit" #32997).

Ruling recorded · 2026-11-13T09:51Z: the maintainer agreed to the narrowing in PR #33079. He chose option A, 「同意收紧」, on the seat's decision card. create_upload_link will refuse at issue a file field whose readonlyWhen holds.

Landing: the contract review passed (6849553232, delta note 6849591863). Once CI is green, the seat accepts and lands after the 18.4.0 merge freeze lifts (#32908; Version Packages PR #29963).
