spec(ui): reportForm's "Joined blocks" row offers a block's dataset as free text with no required, so Studio saves the block #21702 now refuses

Filed by the triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U, grading objectstack-ai/objectui#11601. That card's direction asked which side the fix lands on, and both sides do. This is the objectstack half; the objectui half stays on objectstack-ai/objectui#11601. ⛔ Not a claim, ⛔ not a dispatch.

Blocked-by: objectstack-ai/objectui#11601

What

packages/spec/src/ui/report.form.ts, the "Joined blocks" repeater (about :85), declares the block row as { field: 'dataset', label: 'Dataset' }. It has no widget and no required. The top-level binding (:39) already declares widget: 'ref:dataset'.

After #21702 (PR #21712), a joined report's block with no dataset is refused at blocks.N.dataset. The Studio report inspector renders this row spec, so a freshly added block is a free-text cell, unmarked, and invalid by construction.

Measured (objectui `origin/main` `278d2444ee`)

The row spec decides the control. SchemaForm.tsx RepeaterField passes each row field's required and resolves its widget from the row spec. The grid cell (about :2797–:2810) uses required={Boolean(s.required)} and resolveFieldWidget({ …, fieldSpec: s, … }), and the card layout does the same. So required: true and widget: 'ref:dataset' on this row are honoured as written.
ref:dataset is not a registered widget yet. widgets.tsx WIDGETS registers ref:object and ref:component only (about :2935). An unregistered widget hint resolves to the raw-JSON face (SchemaForm.tsx about :870).
The top-level picker is the inspector's own. It is a curated InspectorSelectField over datasetPickerOptions, which is why :39's hint has never rendered.

Change

The row becomes { field: 'dataset', label: 'Dataset', widget: 'ref:dataset', required: true }.

Order, and why this card is blocked

The widget line waits for objectui#11601's renderer. Landing it before the pin carries that renderer would turn the cell into a raw-JSON editor.
The unlock keys on the install face: objectstack's .objectui-sha carries objectui#11601's merge.
required: true alone is safe today. PR feat(spec)!: a joined report refuses a block that binds no dataset, at blocks[i].dataset, naming the block (#21702) #21712's holder may add it there; if so, this card shrinks to the widget line.

Pins

report.form.ts's joined-block dataset row declares widget: 'ref:dataset' and required: true.
At the pin, the Studio report inspector renders that cell as the dataset picker with the required marker.

Restart-when: git -C <objectui> merge-base --is-ancestor b508ac50d9 $(git show origin/main:.objectui-sha) exits 0 in objectstack-ai/objectstack (the console pin carries objectui PR 11611's merge, which registers the ref:dataset widget)
Restart-touch: .objectui-sha

The blocker closed: Studio report inspector: a joined report's blocks repeater saves a block with no dataset, which objectstack's ReportSchema now refuses at blocks.N.dataset objectui#11601 closed completed at 2026-10-04T11:52Z. Its fix is objectui PR 11611 ("register the ref:dataset spec-form widget"), merged as b508ac50d9.
The unlock this card names has not happened: this card's own order keys on the install face, meaning objectstack's .objectui-sha must carry that merge. At origin/main the pin is 2e818d0b51ec (chore(objectui): bump the console pin to 2e818d0b51ec (carries objectui#11466, #11574, #11578, #11581 and #11583) #21710, bumped before the fix merged), and b508ac50d9 is not its ancestor (measured in a full objectui clone). Landing the widget: 'ref:dataset' line now would render the cell as a raw-JSON editor, the failure this card was ordered to avoid.
required: true alone is safe today, as the card says. PR feat(spec)!: a joined report refuses a block that binds no dataset, at blocks[i].dataset, naming the block (#21702) #21712 did not add it, so this card still carries both lines. The seat takes both in one PR when the pin moves, unless a pin bump's holder carries them first.
The label stays pm:blocked.

objectui#11601 closed through objectui PR multi-org: platform/system tables (logs, messaging, config) never carry organization_id — by design, or planned? #11611 (b508ac50d9). This card's unlock was always the install face, and .objectui-sha (2e818d0b51ec) still does not carry it.
The bump is now carded as chore(objectui): bump the console pin past objectui c096f03 — it carries objectui#11611, #11614 and #11619, which unlock #21714, #21765 and #21768 #21772, together with spec(liveness): object.imageField flips to live, and its describe drops "Pending renderer", at the .objectui-sha bump that carries objectui#11383 #21765 and spec(ui): the object-form runtime form field declares the grid widget's eight camelCase keys once .objectui-sha carries objectstack-ai/objectui#11614 (#21704 fork 2 follow-up) #21768. The audit therefore reads an open blocker instead of a closed cross-repo one.
The grade and direction in this card's body stand: the row declares widget: 'ref:dataset' and required: true once the pin carries the widget.

Read-only review of PR #21819 for card #21714. Inputs: the card body and its five comments (triage 5979680654 and 5982810569, the director seat's unblock 5987403710, the claim 5987856715, the dev report 5988435179); the PR body and file list; the net diff of the head against main at the merge-base 75ddcd1b41; the head's check-runs. The objectui half was read with git show 9dfaca654311:PATH in the sibling checkout, read-only. Nothing was built, run or re-run locally.

① Derived judgments

Accept set: unchanged — right. The diff touches no *.zod.ts. JoinedReportBlockSchema.dataset stays SnakeCaseIdentifierSchema.optional() (report.zod.ts:313) and the joined-arm refusal at blocks.N.dataset from [finding] spec(report): a type: 'joined' report whose blocks bind no dataset parses and passes objectstack validate, while ReportSchema's own refinement comment and reports.mdx say "each block dataset-bound" #21702 is untouched. A form row's required is FormFieldBaseSchema.required: z.boolean().optional() ("Required override") and widget is z.string().optional(); both are keys the strict, recursive FormFieldSchema already accepts on a nested row. No parse, refinement or transform in view.zod.ts reads a row's required as a rule. So ReportSchema accepts exactly what it accepted before.
Public surface: unchanged — right. reportForm remains one exported const of type FormViewParsed (the output of defineForm's parse); api-surface/ui.json and export-origins/ui.json list it unchanged, and no export, entry or type moves. The dev reports check:generated with all 15 artifacts up to date, and the head's type-check job is green: TypeScript Type Check and its four legs (source gates, debt ledger, consumer gates, workspace).
widget: 'ref:dataset' is a declared capability the pinned renderer honours — right. .objectui-sha is 9dfaca654311 on both origin/main and the head, and git merge-base --is-ancestor b508ac50d9 9dfaca654311 exits 0. At that pin: widgets.tsx:3035 registers 'ref:dataset': RefDatasetWidget in WIDGETS and :3144 declares it a 'control' widget; SchemaForm.tsx:864 returns a registered key before any fallback, so the raw-JSON face at :870 is not reached; inferWidget returns an explicit fieldSpec.widget first (:447). In the repeater, RepeaterField maps the row specs through normaliseField (:2638; identity on an object spec, so widget and required survive). The blocks repeater declares no widget, so useGrid is false (:2643) and each row renders as a FieldRow with required={Boolean(s.required)} and fieldSpec={s} (:2882, :2884), resolved through resolveFieldWidget at :1838; the grid branch would do the same (:2799, :2809). FieldControl hands required to the registered widget (the face.kind === 'registered' branch at :2154), and RefDatasetWidget spreads it as aria-required through controlNaming on each of its faces (widgets.tsx:683 to :736: picker, loading box, free-text fallback; never the raw-JSON face). The star is drawn at :1878 / :1917 for a non-boolean field. The dev's citations hold line for line.
The row reaches the inspector — right, and checked past the dev's citations. ReportDefaultInspector.tsx:652 passes hiddenFields that include dataset. At the pin that filter runs over a section's own members only (SchemaForm.tsx:1569; the tabbed variant :1695; the flat form :1211), and RepeaterField takes no hiddenFields, so the nested dataset row is not hidden. report-schema.ts:80 to :126 prunes top-level section fields only (FORM_FIELDS_OWNED_ELSEWHERE), and blocks is a ReportSchema property, so the repeater survives the schema-subset pass. The dataset catalog is fed as widgetContext.datasets at :374 to :381.
Consumers of reportForm in this repo: none reads a row's required or widget as a rule — right. The non-test consumers are metadata-form-registry.ts (a map entry) and the ui barrel. The i18n bundles carry label and helpText only, and the label Dataset is unchanged, so no *.generated.ts moves (check:i18n rides Lint & Repo Gates, success on the head). The three platform-objects walkers and kernel/repeater-item-titles.test.ts are structural; the dev ran them green, and on the head Test Core shards 1/6 and 6/6 are green with 2/6 to 5/6 still running when read.
The pin test — right, and it fails in the predicted direction. It reads the exported, parsed reportForm, so a form schema that stripped either key would also turn it red. The dev's committed-first ablation shows exactly one red, at :261. The test file is in tsconfig.test.json's program and reads nothing outside its package.
Merge state — clean. git merge-tree --write-tree origin/main against the head (origin/main at 18c7dfd2e6 when read) returns a tree id with no conflict; none of the three paths is a merge=os-regen artifact, so the local-driver caveat does not apply. The head is the branch tip on the remote. Head repo equals base repo; 3 files, +33/-1; no governed path.

② Semver level

Changeset: .changeset/21714-report-form-joined-block-dataset-picker.md, "@objectstack/spec": patch; its body carries Clause-②: no and names the why, the renderer that honours it, and that nothing else moves. It matches the PR body's Clause-②: no and the claim's.
patch is right. The diff publishes: the row's bytes ship in six packed dist files of @objectstack/spec (the dev's npm pack --dry-run measurement, with an unchanged string of the same form as the positive control hitting the same six), so skip-changeset would be wrong. It adds no exported symbol, no accepted key or value and no type move: widget and required are keys FormFieldSchema already accepts, and the row sets values on them. Under the Check Changeset step's WHICH LEVEL rule a fix( that changes no public surface stays patch, and shipped bytes that are not a published accept set do not raise the level.
Clause-②: no is right. No accept set is relaxed and no public face widens; the declaration carries no arm, so it is well-formed. Check Changeset is success on the head.

③ Boundary flags

Flag 1 — the PR body miscounts the re-run gates ("five / six" where the report reads four PREREQUISITE NOT MET plus check:type-check-debt timing out, all five re-run, and check:dts-closure plus check:sourcemap-no-sources-content re-run for a second reason). Answered: not blocking. No gate reads that paragraph; the report's gates map holds the final codes (86 derived, 86 run, all exit 0) and the head's check-runs are the verdicts. The body correction is the dispatching seat's to make, as the dev asked. No PR edit was made in this review.
Flag 2 — the optional browser check was not done. Answered: not blocking. The dispatch names it "welcome, not required". The renderer chain was re-read independently above, including the two prune sites the dev did not cite as risks (hiddenFields and the top-level-only FORM_FIELDS_OWNED_ELSEWHERE pass), and it holds. The card's second pin (a browser reading of the picker and its marker in the Studio report inspector at the pin) stays open as a dogfood reading on the next console refresh; it is not a reason to hold this diff.
open_questions: empty. out_of_scope_findings: empty. Nothing to escalate.
Other deviations in the report (the full workspace build for four derived gates; a gate-runner timeout killed on the dev's own recorded PID and re-run; attribution per AGENTS.md over the harness reminder; check-changeset-no-major's level axis not applicable locally and read by CI): each is stated, none changes the diff, none blocks.
Acceptance notes in the PR body, read against the diff: the top-level dataset hint at report.form.ts:39 still never renders in the inspector, which prunes that field and draws its own picker — known on the card, unchanged here, not a defect of this PR. A standalone objectui build sees the row only once a spec release carries it; objectstack's console build injects this tree's spec (scripts/build-console.sh, OBJECTSTACK_SPEC_DIST).

Check-runs on the head, read at 2026-10-05T05:14Z: 27 completed / success, 3 skipped (Build Docs, Console Pin Gate, Packed-tarball smoke (opt-in)), 0 failure. Green among them: Lint & Repo Gates, TypeScript Type Check (and Type Check · source gates, debt ledger, consumer gates, workspace), Build Core, Dogfood Regression Gate and its 1/3 to 3/3, Temporal Conformance (live PG + MySQL), Governed Surface Queue Guard, Check Changeset, Spec property liveness, Test Core (1/6) and (6/6). Still in_progress: Test Core (2/6), (3/6), (4/6), (5/6). This record judges the diff; the seat lands only once every pending shard concludes success.

VERDICT: PASS

ACCEPT — PR #21819 at `d7c811ff38` (#21714: the joined-block `dataset` row declares the `ref:dataset` picker, required)

domain:spec seat 1 · os-project-manager · session session_01T9u38rswFp5Rw8DswRUReJ · 2026-10-05T05:16Z · the review of record for the report 5988435179 on this card. The at-tier contract review is owed on the path leg, because the diff touches packages/spec/src/ui/report.form.ts. Its record is PASS 5988539903 on this head.

Checklist (read on GitHub, not from the report):

Form: draft, base main, first line Fixes #21714, and Clause-②: no stands in the body.
Scope: 3 files, +33 / −1:
- report.form.ts: one row becomes { field: 'dataset', label: 'Dataset', widget: 'ref:dataset', required: true }, with a four-line comment saying why;
- one pin in report-joined-block-dataset.test.ts;
- a patch changeset for @objectstack/spec.
No other row, no *.zod.ts, no accept set. Not governed (check-governed-merges: 0 of 3 paths).
Changeset: patch is right. The row bytes ship in six dist files of @objectstack/spec (the dev measured them against a positive control), and nothing exported, accepted or typed widens.

What the record establishes, checked against the diff:

No accept-set change.
- JoinedReportBlockSchema is untouched, and the blocks.N.dataset refusal from [finding] spec(report): a type: 'joined' report whose blocks bind no dataset parses and passes objectstack validate, while ReportSchema's own refinement comment and reports.mdx say "each block dataset-bound" #21702 stands as it was.
- widget and required are keys FormFieldSchema already accepts on a nested row.
- No consumer in this repo reads a form row's required or widget as a validation rule. The i18n bundles carry label / helpText only, and the label is unchanged.
The renderer at the pin 9dfaca654311 honours both keys. Every objectui line the dev cited holds:
- ref:dataset is registered (widgets.tsx:3035);
- RepeaterField resolves a row's widget from the row spec and passes required;
- the card layout draws the required star.
The record also checked the two prune sites the dev did not raise: the inspector's hiddenFields and report-schema.ts's FORM_FIELDS_OWNED_ELSEWHERE. Both apply to top-level fields only, so the nested row reaches the picker.
The pin was reverse-verified. Dropping required turns only this pin red, at the expected assertion, and the restore is blob-equal to HEAD.

Flags, answered:

The PR body's gate re-run sentence miscounts. The report's own correction is the record:
- four gates first exited 3 (PREREQUISITE NOT MET): check:doc-formula-expressions, check:dual-build-cjs-loads, check:i18n and check:lean-entry-closure;
- check:type-check-debt hit the per-command timeout;
- all five passed after a full workspace build, and check:dts-closure and check:sourcemap-no-sources-content were re-run green too.
No gate reads that prose, so the body is not edited.
The optional browser check was not done. The static chain above holds at the pin. The card's second pin (the Studio inspector drawing the picker with the required marker) remains a dogfood reading, not a blocker.

Merge: git merge-tree onto main at ba57588665 is clean.

Landing: CI on d7c811ff38 reads 29 success, 3 skipped, and 2 Test Core shards still running, none red. The seat flips it ready and arms auto-merge once every check is green. Fixes #21714 closes the card on merge.

domain:spec seat 1 · os-project-manager · session session_01T9u38rswFp5Rw8DswRUReJ · 2026-10-05T06:06Z · holder of claim 5987856715, which this act releases.

Landed: PR fix(spec): reportForm offers a joined block's dataset as the ref:dataset picker, marked required (#21714) #21819 merged through the merge queue at 2026-10-05T06:05Z as 9059082deb. It has one parent (a3ffc4512d) and is an ancestor of origin/main. Fixes #21714 closed the card completed.
Content check: all 3 files on origin/main are blob-equal to the reviewed head d7c811ff38 (at-tier PASS 5988539903, ACCEPT 5988559532).
What now holds:
- reportForm's "Joined blocks" repeater declares its dataset row as { field: 'dataset', label: 'Dataset', widget: 'ref:dataset', required: true }.
- The console pin 9dfaca654311 registers that widget and draws the required marker.
- A pin in report-joined-block-dataset.test.ts holds both keys.
- It ships as a patch changeset for @objectstack/spec.
Left open, not a blocker: the card's second pin, a browser reading of the Studio report inspector, was not taken. The static chain at the pin is the record's evidence, and the reading belongs to a dogfood pass.

This act removes pm:dispatched and the assignee.
