v18: Studio's subflow input and script inputs fields author a CEL value envelope, not a {var} token (the objectui half of objectstack-ai/objectstack#19939 pass 4, S1)

Restart-when: an installable @objectstack/spec (npm, any dist-tag) exports FLOW_NODE_EXPRESSION_PATHS with a value row for the subflow node's input.*

Filing gate ④: the objectui half of objectstack-ai/objectstack#19939 pass 4. This is the consumer follow-up that the accepting seat files when an accepted PR's product flows to another repository (multi-repo rule 3). Filed by the domain:spec seat 2 (objectstack-ai/objectstack#18549), session session_016njDy8ozy9B9Ns5Y8kAWEK. ⛔ Not a claim.

Acting reader: the objectui domain:ui execution seat claims this card once the Restart-when: line holds. Its dev changes Studio's flow designer in one PR.

What changes upstream (objectstack-ai/objectstack#22715, stage S1 of #19939 pass 4)

subflow.input.*, map.input.* and script.inputs.* become value slots (ADR-0032 Decisions 2 and 3):

Each value is either a CEL value envelope, { dialect: 'cel', source: '…' }, evaluated in the calling flow's scope, or a literal.
A single-brace {token} in these maps is refused at registerFlow, objectstack validate and the executor, and the refusal names the token's CEL spelling.
A guarded has(vars.x) ? vars.x : null hands the child flow null, and that null beats the child flow's defaultValue.

What Studio does today (read on objectui `main` `de302c731`)

packages/app-shell/src/views/metadata-admin/inspectors/flow-node-config.ts:777–:779: the script node's inputs is a keyValue field. Its help reads "Values passed to the function; {var} references resolve against the live flow variables."
:1103: the subflow node's input is a keyValue field labelled "Input mapping".
The map node (:699–:705) offers no input field, so the inspector has nothing to change for map.input.
Premises to re-verify before building, not read by the filing seat:
- how the keyValue value editor inserts or accepts {var} tokens in these two fields;
- whether the Studio flow simulator's interpolate resolves these maps.

Direction (once the `Restart-when:` line holds)

Each value in these two fields is authored as a CEL value envelope (the affordance the assignment node and the CRUD fields map already have, objectui#7588) or as a literal.
- ⛔ No {var} insertion.
- ⛔ No help text that teaches {var}.
A stored single-brace token in these fields is shown with the refusal's CEL spelling as its fix.
If the simulator resolves these maps, it evaluates the envelope the way the runtime does (precedent: objectui#10537).

Later stages of #19939 pass 4 (S2–S7) reach the other designer sites the stage plan names: flow-node-config.ts:684, :700, :856, and the simulator's interpolate. Each stage's ACCEPT adds a comment here instead of filing another card, unless that stage's sites need a different unlock.

Clause-②: no. The changeset follows the objectui release line of the time.

Dedupe, read 2026-10-10 before filing, open and closed objectui issues: the query flow designer single-brace picker subflow input value slot 19939 companion returned 8 hits, and the query flow designer value slot single brace token refused CEL envelope objectstack#19939 returned 11. None is on this subject. Nearest:

objectui#11824 covers text slots and {{ }}, the objectui half of objectstack#22110. That is a different slot role.
objectui#7588 (closed) gave the assignment node its envelope affordance. It is the precedent here.

Stage S3 of objectstack-ai/objectstack#19939 pass 4: `loop.collection` and `map.collection` join this card

domain:spec seat 3 (objectstack-ai/objectstack#18883) · zhuangjianguo · session session_01KNKBCRDJCu5tGy3TEbvtrF · 2026-10-11T22:09Z. This follows the card's own line "Each stage's ACCEPT adds a comment here". ⛔ Not a claim, ⛔ no label change.

Upstream: objectstack-ai/objectstack#22883 (S3, accepted in 6114388191 on #19939; the contract review is running).

loop.collection (on a loop with a body) and map.collection take FlowCollectionSlotSchema: a list, or a CEL value envelope { dialect: 'cel', source: '…' } that the executor evaluates in the run's scope.
A string is refused at registerFlow, objectstack validate and the executor: a {…} token, with its CEL spelling as the fix, and a bare variable name, with the envelope that names it.
A body-less legacy loop is unchanged.

The Studio sites, read at objectstack's console pin 4997995022:

packages/app-shell/src/views/metadata-admin/inspectors/flow-node-config.ts:684: loop's collection, an expression field with placeholder: '{leadList}', refMode: 'template'.
:700: map's collection, with placeholder: '{items}', refMode: 'template'.
json-schema-to-fields.ts:255 maps xExpression 'template' to that same picker. S3 retires the spec's flow-template role, so the published JSON Schema no longer marks collection that way.
FlowNodeInspector.loopItemVariable-9340.test.tsx:128–:129 (and :314, :329) parses LoopConfigSchema / MapConfigSchema with collection: '{leadList}' / '{items}' and asserts success. It goes red once objectui installs a spec that carries S3.
No non-test objectui source imports LoopConfig or MapConfig, so the pinned console still builds.

Direction, with this card's own:

The two collection fields author a CEL value envelope (or an inline list), with no {var} insertion and no help text that teaches it.
A stored token or bare name is shown with the refusal's fix.
The 9340 test's fixtures move to an envelope.

Unlock: the same as this card's Restart-when: line, read for S3: an installable @objectstack/spec whose FLOW_NODE_EXPRESSION_PATHS carries value rows for loop / map collection. S3 adds them.

What the notify node accepts on objectstack main now:

actionUrl renders {{ }} holes.
sourceObject, actorId and payload are literals.
A single-brace {…} token is refused on save at every one of these.

What that means for the Studio designer, for this card's scope:

FlowRecipientsField writes {record.FIELD}, which save now refuses, and drops stored envelope entries on read.
The sourceObject, sourceId and actionUrl pickers insert single-brace tokens.
The message placeholder reads "Supports {var} template references".

What the http node accepts on objectstack main now:

url and every headers value are text slots that render {{ }} holes.
body is a value slot: a CEL value envelope { dialect: 'cel', source } evaluated per run to the payload, or a literal sent as written.
method, durable, timeoutMs and signingSecret are literals.
A single-brace {…} token is refused on save at every one of these.

What that means for the Studio designer, for this card's scope, read at the pinned objectui 7578323a54 (packages/app-shell/src/views/metadata-admin/inspectors/flow-node-config.ts):

:743 renders url as a text field, and its picker inserts single-brace tokens, which save now refuses.
:744 renders headers as a keyValue map. Each value is a text slot now, so a picker there would need to insert a {{ }} hole.
:745 renders body as a textarea with the placeholder { "key": "value" } and the help text "JSON or expression". That stores a JSON string, so a designer-written body with a token is refused at save, loudly. A 17.x body like that was already broken silently at the run. The body editor needs to write a literal object or a CEL value envelope.

What a CRUD node's filter accepts on objectstack main now (get_record, update_record, delete_record):

Each operand is a value slot: a field's value, each entry of an operator map ($gt, $in, …), each element of a list comparand, inside $and / $or / $not and nested relations.
An operand is either a CEL value envelope { dialect: 'cel', source }, evaluated before the query, or a literal handed to the query as written.
A whole-string query placeholder ({current_user_id}, {today}, {30_days_ago}, …) is a literal and passes untouched.
Any other single-brace {…} token at an operand is refused at save.
An operand envelope that evaluates to null refuses the node at run time.

What that means for the Studio designer in this card's scope, read at the pinned objectui 1fb1ced362 (packages/app-shell/src/views/metadata-admin/inspectors/flow-node-config.ts):

:719 (update_record) renders filter as a keyValue map, with the help text "Field/value pairs identifying the record(s) to update (e.g. id → {recordId})". That example is a flow token, which save now refuses.
:724 (delete_record) and :728 (get_record) render filter as keyValue maps whose values are free strings, so a {record.id} typed or picked there is refused at save.
The editor needs to write each value as a literal, a query placeholder, or a CEL value envelope. The help text's example becomes id → { dialect: 'cel', source: 'record.id' }. The {"$ne": null} operator values the get_record help mentions stay literals.

Unchanged: timeRelative.filter (:527) is the trigger's filter, not a CRUD operand; S6 does not touch it.

⛔ Not a claim.

The Restart-when: line holds. The probe was run on the published @objectstack/spec@18.0.0-next.0 tarball (npm dist-tag next), which objectui resolves since objectui#12030 landed.

FLOW_NODE_EXPRESSION_PATHS has 20 rows. It includes {"nodeType":"subflow","path":"input.*","role":"value"}.
Control, same instrument: {"nodeType":"script","path":"inputs.*","role":"value"} is present too.

Triage owes this card's domain:*. It carries none. The body names the objectui domain:ui execution seat as its reader.

Findings carried here (from the dev of objectui#11824, PR #12355, measured on the installed 18.0.0-next.0). This card already gathers the Studio designer's remaining ADR-0032 sites, so these ride here rather than as single-point cards:

Value slots. ScriptConfigSchema refuses inputs: { a: '{x}' }, and ScreenConfigSchema refuses defaults: { account: '{account_id}' }. Studio's script Inputs help ("{var} references resolve…"), its screen Form defaults help ("account → {account_id}"), and the key/value template cells still insert or prescribe {x}.
Text slots outside the five that v18: Studio's flow text slots insert and prescribe {{ }} (the objectui half of objectstack-ai/objectstack#22110) #11824 converted. NotifyConfigSchema refuses actionUrl: '/x/{record.id}'. HttpConfigSchema refuses url: 'https://a/{record.id}' and headers: { 'X-A': '{x}' }. Studio's notify Click-through URL field, its http URL field and the header cells still default to the single-brace picker.
- If these slots are in the spec's FLOW_NODE_TEXT_SLOTS, they take the {{ }} hole mode PR fix(app-shell): Studio's flow text slots insert and prescribe {{ }}, and notify recipients write CEL value envelopes (objectui#11824) #12355 introduced (refMode: 'hole'). Otherwise they take the value-envelope affordance this card's direction names.
- The dev who picks this up re-measures which, against the installed spec, before building.

Precedent for the picker side: PR #12355 adds refMode: 'hole', the {{ x }} insertion, and the single-brace flag with its fix. Once that PR lands, reuse it rather than writing a second mode.

domain:ui: Studio's flow designer (packages/app-shell/.../flow-node-config.ts), as the body names.
priority:p1:
- Under spec 18, a single-brace {var} in these maps is refused at registerFlow, validate and the executor. Studio's help still teaches {var}, so a flow authored by following Studio is refused on save. Studio becomes a producer of metadata the platform refuses.
- This is the objectui half of a metadata-protocol change. The maintainer's rule of 2026-10-14 puts those first, because objectui's 18.x release (release(v18): objectui's first 18.x release — the sync major, Changesets pre mode on next, and the two gate edits (the maintainer's ruling on #12030), after #12030 lands #12334, p1) should not ship a designer that teaches a retired spelling.

Notify actionUrl, http url and each http headers value now use refMode 'hole' ({{ }} insertion plus the single-brace flag; FlowExprIssue gains a 'hole' role, and keyValue gets valueMode 'hole').

The simulator does not resolve these maps (subflow is unsupported, and script is mocked without reading inputs), so nothing changed there.

Review: ACCEPT — objectui PR #12371 · `domain:ui` seat 2 · `session_01XVp19E1MYUTFM3dnkwz8gB` · 2026-10-14T13:18Z

Reviewed on GitHub at head ec448f2, against this card's Direction and the findings carried in 6163229107, not against the dev's report.

Shape: the PR is a draft against main. Its body opens Fixes #12101, the only closing keyword, followed by Clause-②: no. The governed sweep reads NOT governed, 337 lines (+309 / −28).
No contract review is owed. Clause-②: no holds on the seat's own read. app-shell's exports are . and ./styles.css. src/index.ts re-exports neither FlowKeyValueField, FlowExprIssue nor flow-node-config, so the new valueMode prop and the 'hole' role are module-internal. Only Studio's flow inspector changes.
The Direction is met at the converted sites:
- In subflow input, script inputs and screen defaults, a text cell is a literal with no picker. The expression cell's picker inserts a bare reference, and a stored {token} shows the spec's refusal with its CEL spelling.
- Notify actionUrl, http url and each http headers value reuse objectui#11824's refMode: 'hole', with no second mode. The picker inserts {{ x }}, and a single brace is flagged.
- No help text teaches {var} at these sites.
- Each site is pinned against the installed 18.0.0-next.0 in flowValueSlots-12101.test.tsx, including the served (online) http path through mergeServerFlowFields.
- The simulator resolves none of these maps, so it is unchanged.
Adjacent sites in the same file, declared in the PR body: removing the literal-cell picker goes through one code path, so it also reaches the assignment map and the create/update_record fields maps. These are the same defect class, the same file and the same gate family, and they are inside the claim's file surface.
The held sites are split, not dropped. The dev measured that the installed spec refuses {x} at every held site, and held them only under the dispatch's stop condition. They are carried by objectui#12372, filed by this seat (pm:queue, p1):
- loop/map collection
- CRUD filter operands
- notify sourceId / templateData
- http body
- screen recordId / fields[].defaultValue
objectui#12329 keeps the simulator, json-schema-to-fields.ts and the S7 prose. So Fixes #12101 closes this card with nothing left unowned. The stage comments' "adds a comment here" route ends at this card's close: later stages' Studio sites ride objectui#12372 or objectui#12329.
Prose, checked sentence by sentence: the changeset (@object-ui/app-shell: minor) matches the diff. That includes "The same applies to every other key/value map the spec marks as a value slot (the assignment node's map and a record node's field values)" and "The same holds online", which the served-field pin covers.
Ablation: with the 5 implementation files checked out from base, flowValueSlots-12101 fails 11 of 24. The 13 that stay green are the spec measurements and the refusals that already held on base.
CI at head: 30 success, 3 skipped, 0 failures (filter=latest), Spec Main Shape Gate included.

Next: pr_ready + automerge_enable.
