metadata: an object's fields come back in alphabetical order after save/publish, so the default create form loses the declared field order

Edition: ObjectOS Cloud (os-test environment, MCP connection)

What happened

An object was created over MCP create_metadata(type: object) with its fields map in business order:

leave_no, employee_name, department, leave_type, start_date, end_date, days, reason, status, approver, approval_comment, attachment

After publish, describe_object returns the fields (after the system columns) in alphabetical order:

approval_comment, approver, attachment, days, department, employee_name, end_date, leave_no, leave_type, reason, start_date, status

The console's default create form ("新建请假申请", with no form view declared) follows that order, so it opens with 审批意见 / 审批人 / 证明附件 first and 员工姓名 / 开始日期 at the bottom: the form reads as random to an end user.

Expected

The declared order of fields is the order the default form, the default list columns and describe_object use. A JSON object's insertion order is the only ordering an author has for fields, and it should survive save and publish. Today the author has to hand-write a form view just to get a sensible field order.

Steps

Create an object whose fields keys are not in alphabetical order (MCP create_metadata or apply_blueprint).
Publish it, then describe_object → fields come back alphabetically.
Open the object's list and click 新建 → the form follows the alphabetical order.

⛔ Not a claim.

Lane: domain:server (metadata save and publish; describe_object).
Grade: p2. Declared field order is lost after save or publish, so the default form and list columns read alphabetically. It is a usability defect with no data loss.

File surface: the hop that reorders ObjectSchema.fields on create → publish → describe, expected in packages/metadata-core/**, packages/metadata/**, packages/metadata-protocol/** or packages/mcp/**, named by the dev's step 0 before editing; their tests; one changeset (stop on breach; explain in the report)
Container & model: M, mode:thread, model: default tier (dispatch-gates --tier: no path-derived mandate), effort: high
Clause-②: no
Metadata-protocol: none
Responsibility: platform code (objectstack) on the metadata save/publish/describe path produces the sort; no platform path covers it today (authors hand-write a form view); every author who creates an object with non-alphabetical fields reaches it
Thread-read: 6789288757
Premise: holds (read at 7d82b2da: canonicalize.ts keeps object.fields order only when the type is passed; type-blind sorts remain on the tree; the reorder hop itself is the dev's step 0 measurement)
Serial constraints cleared: none on a named file; open PR #32327 edits protocol-meta-item-face.ts / protocol-meta-layered-reads.ts — if step 0 lands the fix there, the later lander merges main

Step 0 did not reproduce the card on objectstack 7d82b2da: every hop this repository owns keeps the declared fields order. No code changed, no PR. The create_metadata / apply_blueprint tools the card names are not implemented in this repository; docs/adr/0070-package-first-authoring.md names ../cloud (service-ai-studio) as their home. Carrier: cloud.

Per-hop readings (probe: showcase dogfood boot plus MCPServerPlugin; package app.ordprobe32398; object ordprobe_leave with the card's 12 fields in the card's order):

hop	sqlite-wasm (database file)	memory driver
`PUT /meta/object/NAME?mode=draft&package=PKG`	200	200
`POST /packages/PKG/publish-drafts`	200, published 1	200, published 1
`GET /meta/object/NAME`	declared order	declared order
`GET /meta/object` (list)	declared order	declared order
objectql `registry.getObject`	declared order	declared order
MCP HTTP `describe_object`	8 injected system columns, then declared order	same
stop, cold boot on the same file, `GET` + registry	declared order	n/a (in-memory)

Artifact door (MetadataPlugin artifactSource local-file, build-shaped showcase artifact): 6 showcase objects whose declared fields are not alphabetical; the artifact keeps their order and the served order equals the declared one.

Release: claim 6795835969 (domain:server#3 · session_01Utp6CaAUev5V62cLHhQwBi) · 2026-11-11T12:44Z · reason: premise false in objectstack · next: triage, for a cloud re-route

Reading: os-dev-report 6796124697 has premise_still_valid: false and pr: null. Measured at 7d82b2da, every hop keeps the declared field order: draft PUT → publish-drafts → GET /meta/object/<name> → registry → MCP describe_object → cold boot. That holds on sqlite-wasm, on the memory driver and through the artifact door. create_metadata and apply_blueprint are not in this repo; ADR-0070 Consumers names cloud service-ai-studio as their home. So the reorder is on the cloud path, or in the os-test deployment's driver, and neither is measurable from here.
Ask to triage: route the card to cloud (carrier: cloud), or close it with a cloud card. The card returns to pm:queue with pm:retriage and no assignee. Resume-from: none (nothing pushed).

⛔ Not a claim.

Reading: domain:server#3's step 0 (6796124697) measured every objectstack hop and found the declared fields order kept throughout. Those hops are the draft save, publish-drafts, the /meta item and list reads, the registry, MCP describe_object, a cold boot, and the artifact door, run on sqlite-wasm and the memory driver.
Producer: create_metadata and apply_blueprint, the tools the card names, live in cloud's packages/service-ai-studio (authoring-whitelist.ts), not in this repository.
Lane: domain:cloud + repo:cloud.
One hop is not measured: the hosted storage. If os-test runs on PostgreSQL through objectstack's driver-sql, the claimer first checks the order there. If that platform hop reorders the fields, it comes back as its own domain:server card.
