Studio 变更 drawer: on publish, offer 补默认值 per new field that carries a default, through the protocol's opt-in backfill (ruling A on cloud#2924)

Unblocked: #12971 closed completed when PR #13043 merged as 8aa8e3e1e5 (objectui's pin is now objectstack main f4755a68a797); re-derived with no new blocker (unlock comment below).

Filed by the director seat (summon #43 continuation 4, session_01QJC7i981TSs9L1CGJK59Ax) on the maintainer's ruling A on objectstack-ai/cloud#2924 (batch #362 item 1, 「其他同意」; the ruling record is that card's Ruled: line), under the maintainer's standing 口径「平台相关的功能，应该尽量先改平台」: the protocol half is objectstack-ai/objectstack#24253 and lands first. ⛔ Not a claim. Filing gate ①: a ruled design element with a named consumer.

What is measured

The ruled StudioCopilot design (cloud#2924, the maintainer's 「同意」): a copilot change to a live app with records is saved as a Studio draft; the applied card says 「已有 N 条记录的 X 为空，发布时可选补 0」. The console's 变更 drawer publishes through publishPackageDrafts, which today takes no backfill; the card's 「可选补 0」 therefore stays off until this lands.

Scope

In the 变更 drawer, each pending field addition that carries a defaultValue shows an unchecked 「补默认值（N 条已有记录）」 option; publishing passes the checked fields to the protocol's opt-in backfill and shows the per-field count the response returns.
No option for a field without a default; nothing is backfilled unless checked.
Clause-②: no (a drawer control over an existing publish action; no new @object-ui export).

Done when

A test: a draft adding a boolean with a default over N rows publishes with the option checked and the response count N is shown; unchecked, nothing is written.
cloud's applied-card copy may then say 「发布时可选补 0」 (cloud#2924's follow-up, one line).

Related: objectstack-ai/cloud#2924, objectstack-ai/objectstack#24253, #12894 (the card rendering half).

`Blocked-by:` re-pointed to the release · `pm:blocked` stays · triage seat · `session_01AavokzJ5DndAwitDXvKy4U` · 2026-10-18T09:22Z

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015). ⛔ Not a claim, ⛔ not a dispatch.

metadata-protocol: publishPackageDrafts takes an opt-in per-field backfill of existing rows with the new default, so a copilot draft that adds a field can fill existing records on publish (ruling A on cloud#2924) objectstack#24253 (the protocol half) is closed. It landed as objectstack 1e001c7df (PR feat(metadata-protocol): publishPackageDrafts takes an opt-in backfill of new fields' literal defaults, written as the caller objectstack#24269) at 08:11Z.
This card still cannot start honestly. The opt-in backfill on publishPackageDrafts reaches the console only in the first @objectstack/* release that carries 1e001c7df. npm next is 18.0.0-next.3, which does not carry it.
So the body's Blocked-by: line now names chore: version packages (next) objectstack#24168, the Version Packages PR that publishes next.4. That PR is the maintainer's to merge. The dispatching seat confirms next.4 is on npm before the dev starts. The engine seat's note stands: offer 补默认值 only for a literal default.

⛔ Not a claim.

The blocker has closed. objectui#12971 closed completed when PR chore(deps): build @objectstack/* from objectstack main 2ec6827962 and follow its contract (objectui#12971) #13043 merged as 8aa8e3e1e5. objectui's .objectstack-sha is now objectstack main f4755a68a797 (18.0.0-next.5).
Re-derived, no new blocker. The pin f4755a68a797 carries 1e001c7df (the publishPackageDrafts backfill).
The Blocked-by: line in the body is replaced with an Unblocked: line in the same act.

Domain: domain:ui
Seat: domain:ui#1
File surface: packages/data-objectstack/src/metadata-client.ts (MetadataClient.publishPackageDrafts(packageId) gains the protocol's opt-in backfill, about :1527 of objectui main bc98626; it sends body: '{}' today), the Studio 变更 drawer and the publish path it calls (packages/app-shell/src/preview/DraftChangesPanel.tsx, and views/studio-design/StudioDesignSurface.tsx about :1448 or preview/usePublishAllDrafts.ts, whichever the drawer's Publish runs), the user-facing strings it adds (@object-ui/i18n packs or the app-shell table, as the drawer already does), tests beside them, and one .changeset/12929-publish-backfill.md. Stop on breach; explain in the report.
Container & model: M, mode:subagent, model: opus (default tier; dispatch-gates --tier --repo objectstack-ai/objectui over this surface reads no path-derived mandate)
Clause-②: yes
Responsibility: n/a — not a defect card (a ruled design element: ruling A on objectstack-ai/cloud#2924, protocol half objectstack-ai/objectstack#24253)
Thread-read: 6269724388
Serial constraints cleared: no open objectui PR touches metadata-client.ts, DraftChangesPanel.tsx, StudioDesignSurface.tsx, usePublishAllDrafts.ts or PackagesPage.tsx (open PRs #13087, #13086, #13085, #13084, file lists read at this claim). Prerequisite re-verified: objectstack 1e001c7df (PR objectstack-ai/objectstack#24269, publishPackageDrafts takes backfill) is an ancestor of objectui's pin f4755a68a797 (git merge-base --is-ancestor, exit 0; control leg ca426cb65d, exit 0). PublishPackageDraftsResponse.backfillApplied is declared at the pin (packages/spec/src/api/protocol.zod.ts:1582).

Why Clause-②: yes, correcting the card body's Clause-②: no: MetadataClient is exported from @object-ui/data-objectstack (src/index.ts:7273), and its publishPackageDrafts takes only packageId today. Passing the protocol's backfill through it adds an option to a published method's accepted input. That widens a published face, whatever the drawer itself adds. The card's line was written before that client existed on the path (it reasoned from "no new @object-ui export").

PR	#13090 merged through the merge queue at 2026-10-19T22:09Z; merge commit `6058bf8`, which `git merge-base --is-ancestor` places on `origin/main` (exit 0)
queue	no `gh-readonly-queue/main/pr-13090-*` branch remains
landed content	on `origin/main`: `metadata-client.ts` sends `backfill` only when given (`options.backfill !== undefined`, 1 hit); `DraftChangesPanel.tsx` carries `export function backfillCandidates` (1 hit). Positive control: `async publishPackageDrafts` is still the one door (1 hit)
records	claim `6277021967` (`Clause-②: yes`, correcting this card's body line), dev reports (round 0 and patch round 1), contract review `6278057016` (`TIER_DEFAULT`, PASS), ACCEPT `6278072404`
closing	closed `completed` at 2026-10-19T22:09Z through the PR's `Fixes #12929`, the only card closed since the merge; `pm:dispatched` is removed in this act

Follow-up named by this card's body: objectstack-ai/cloud#2924's applied-card copy may now say 「发布时可选补 0」 (cloud's one-line follow-up). It reaches users when cloud's objectui pin moves past 6058bf8.
