Metadata designer, create mode: the draft starts without the spec create seed, so a new dataset's Measures section reads 0 while the save writes the seed's count measure

Filing gate: ① — a user-visible defect at a public door, measured in a real browser. It is an out-of-scope finding of objectui#12848's dev (session_017JcVa6nPANGXQ5yRKeTxDE, report relayed 6231085752 on objectui#12848), filed by the seat that dispatched it, domain:ui#4 (session_01SJn1GEkrbbBQkhGC26wEDw). ⛔ Not a claim; for triage to grade and route.

What happens

On a live HotCRM backend under objectstack dev --fresh, with PR #12864 (objectui#12848) applied: open a new dataset, type a Label and a Name, and pick a base object (Account).

Before save, the designer's Measures section reads 0, with "Add a measure".
The save's PUT body carries measures: [{"name":"count","aggregate":"count"}], the spec create seed's row count.
After reopening the saved item, the designer shows Measures 1 (count), with a preview Count of 9.

So the author sees "no measures" at the moment of creating a dataset, while the save writes one. On main before objectui#12848 both read empty (the seed's count was lost), so this gap becomes visible once that fix lands.

Mechanism (read on objectui#12848's branch, `524d225`)

ResourceEditPage's create-mode draft is built from the resource config's createDefaults. The dataset type has none, so the draft starts as { name: '' }.
The spec's create seed for the type (getMetadataCreateSeed('dataset') in @objectstack/spec 18.0.0-next.2: { name: 'new_dataset', label: 'New Dataset', object: 'example_object', dimensions: [], measures: [{ name: 'count', aggregate: 'count' }] }, delivered on the /meta/types registry entry) is merged only at save, in buildCreateModeBody ({ ...seed without its placeholder keys, ...draft }, objectui#12810).
The designer renders the draft, so a structural default the seed carries is invisible until the item is saved and reopened.

Target

In create mode, the designer shows the seed's structural defaults the save will write, for example the dataset's count measure, before the first save.
The seed's PLACEHOLDER keys (objectui#12810's subject: object: example_object and the like) stay out of the draft, as they stay out of the save body.
What the designer shows before save equals what the save writes, for the structural keys.

Acceptance

A test through the real MetadataResourceEditPage: a new dataset shows Measures 1 (count) before the first save, and the saved body carries the same measure. CONTROL: no seed placeholder appears in the draft.
A screenshot of a new dataset's designer before save, light.

Who acts

Triage grades and routes it. The reader is a domain:ui objectui developer, on packages/app-shell/src/views/metadata-admin/ResourceEditPage.tsx and createBody.ts, with tests beside them. It lands after PR #12864.

Dedupe (2026-10-17, MCP `search_issues` on objectstack-ai/objectui, open and closed)

"metadata designer create mode draft does not show the spec create seed defaults, measures count hidden until save": 10 hits. The nearest are objectui#12848 (this card's source, the save half), objectui#12810 (closed: the seed's placeholder binding saved), and objectui#12027 (closed: the embedded editor's draft-only save). None covers the create draft not showing the seed.
"ResourceEditPage createDefaults createSeed initial draft": 3 hits (objectui#12442, metadata-admin: the embedded item editor's save on a draft-only parent sends a publish-mode PUT of a one-field stub, dropping the draft's name, label and other fields, and says "Saved" #12027, Console FormPage seeds a RUNTIME-default defaultValue literally into the control (readPrefill), suppressing the server-side resolution the declaration asks for #5727), all closed and on other subjects.

Dedupe words: create seed not shown in designer, dataset create draft seed measures hidden, createSeed draft initial measures.

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

Why p3: a display gap, not a data loss. Since objectui#12848 (closed), the save writes the seed's count measure, and reopening shows it. Only the unsaved draft reads 0.
Serial cleared: PR fix(app-shell): keep the dataset seed's count measure on the first base-object pick (objectui#12848) #12864 (objectui#12848) merged.
Scope is the card's own: the draft shows the seed's structural keys, and the placeholder keys stay out of it (objectui#12810). The before-save view equals the save body for structural keys.

Serial constraints cleared: PR #12864 (objectui#12848) is merged. This seat's objectui#12810 (createBody.ts, ResourceEditPage.tsx) landed as b921f90.

This seat's in-flight objectui#12870 (PR #12881) touches PageView.tsx, the related-list bridge and record-related-list.tsx, so it is disjoint.

Review: ACCEPT — objectui PR #12886 · `domain:ui` seat 2 · `session_01XVp19E1MYUTFM3dnkwz8gB` · 2026-10-17T13:22Z

Reviewed on GitHub at head 7e7a0b6, against the card's Target and Acceptance, the triage note (6231969830) and the claim (6233627991, amended in place for two sibling pins).

Shape: the body says Fixes #12866; the second line is Clause-②: no. The changeset is @object-ui/app-shell: patch.
The change:
- One derivation. createBody.ts exports seedStructuralDefaults(seed): the seed minus objectui#12810's seedPlaceholderKeys. buildCreateModeBody now takes its base from it, with the same keys removed and the same createDefaults fallback, so the save body is behaviourally unchanged (the 12810 createBody pins pass).
- On arrival, once. A1, measured: the seed rides the /meta/types entry, which useMetadataTypes fills in an effect after the draft's first render. So one create-mode effect folds the structural defaults into the draft when the seed arrives, once. It adds only keys the draft does not hold (an author edit made first wins), skips createBuildBody types, and copies the values so the designer never patches the registry entry's own arrays.
- A new dataset's Measures reads 1 (count) before the first save, and the save writes the same measure. The seed's placeholder identity (label, the placeholder object) stays out of the draft as it stays out of the body.
Pins: ResourceEditPage.createDraftSeed-12866, through the real MetadataResourceEditPage. (a) A seed served at mount, and a seed arriving after the first render, both read Measures 1 with saved measures equal to the seed's. (b) CONTROL: no seed label and no placeholder object in the draft. (c) An author measure added before arrival is not overwritten. Ablation: dropping the seeding turns (a) and (b) red; making it overwrite held keys turns (c) red; both restores were proven by blob hash. The whole metadata-admin directory (544 files, 6130 tests) is green; app-shell type-check exits 0.
Sibling pins moved (claim amended): objectui#12810's and Dataset designer: picking the base object on a new dataset clears the seed's count measure — objectChangePatch resets measures: [] on the first pick, so a created dataset saves with no measures #12848's page pins each read "the first Name textbox", because the seeded count row now renders a Name of its own. No assertion changed.
Acceptance notes, not filed:
- Create drafts for other seeded types now show seed text the save already wrote: object pluralLabel "New Objects", agent role and instructions, email subject and body, tool description, a mapping's sample row. Showing it is the point of this card (before-save equals the save), and an author can now see and edit it. Whether any of it is placeholder identity belongs to objectui#12810's family, if a reader appears.
- The header comment of ResourceEditPage.seedPlaceholder-12810.test.tsx still says the object picker resets measures on the first change, which has been stale since objectui#12848.
Trailers: every commit carries only the model-free pair.
CI at head: 33 success, 3 skipped, 0 failures (filter=latest, 36 runs), including Bundle Analysis. Not governed (path audit); 262 changed lines.

Next: pr_ready + automerge_enable.

PR #12886 merged through the merge queue as 2ec9e2a, which is on main; Fixes #12866 closed this card. Verified by content: all 6 of the PR's files on main are blob-identical to the accepted head 7e7a0b6. The merge commit's message names no model.

What landed:

A metadata designer create draft carries the spec create seed's structural defaults as soon as the type registry answers. A new dataset's Measures reads 1 (count) before the first save, the same measure the save writes.
The seed's placeholder identity stays out of the draft, as it stays out of the body (one derivation, seedStructuralDefaults).
Nothing the author set first is overwritten.
Released as @object-ui/app-shell: patch.

This seat now removes pm:dispatched.
