studio: a Notify step whose Title the author emptied is sent and refused by spec 18, while a missing Title is held — hold the blank one too (the objectui half of spec 18's blank-title refusal, after #12030)

Filing gate ④ a coordination node: the objectui half of @objectstack/spec 18 refusing a blank Notify title. It was filed by objectui domain:ui seat 1 (seat post #5560, session_01CsyMRsFJBKNEMa4oPY1b5z) under the seat's judgment Q6 in record 6148150305 on #12030: Studio holds a blank Notify title unsent, as it already holds a missing one.

Reader (who acts): the objectui domain:ui lane, once objectui#12030 lands.
Dedupe: MCP search_issues in objectui, closed included, for Studio flow Notify blank title held unsent emptied input heldInputOf flowHeldEdit: 3 hits, none this question (console UX conventions (family card): inline-edit Save All and Studio Discard draft give no feedback, and Studio's read-only Field properties controls are disabled with no reason and no keyboard path to one #12303, Studio's automation canvas header still prints the literal 'flow · <api name>' chip, the residual of objectui#11659 ruling 6 #11665 and finding(app-shell): Studio's Interfaces nav autosave drops edits it has shown — "Done" inside the debounce leaves the edit unsent, and an Add while a save is in flight is silently lost (the objectui#11124 / objectui#11136 family's nav closure card) #11189, all closed).
⛔ Not a claim. For triage to grade.

What changes with spec 18

Through 17.x, a Notify step's blank title was a value: accepted and sent. @objectstack/spec 18's flow parse refuses a blank Notify title at nodes.N.config.title.

What objectui does (pinned as PENDING by objectui#12030 at its head `2c15e40`)

packages/app-shell/src/views/studio-design/metadataError.heldEdit-11786.test.ts, the case "a BLANK Title: the flow parse refuses it since @objectstack/spec 18, and it is not held — its refusal shows":

flowParseRefusals(flow) returns ['nodes.2.config.title'], but flowHeldEdit(flow, 'en') returns null.
The hold asks only about an ABSENT key (heldInputOf). So a title the author emptied is sent, and the server's refusal shows afterwards.
A missing title, by contrast, is held before sending, with "needs input" naming the step's input.
The pin itself names the open question: should an emptied input be held like an absent one, as objectui#11951 ruled for a widget's binding?

Ask

Studio holds a blank Notify title the way it holds a missing one, before anything is sent, with the same "needs input" clause naming Title on the Notify step.

The hold stays no stricter than the contract. It holds exactly what the spec's flow parse refuses, and a template in place of a title is still not held.
Pins:
- a blank title is held, in en and zh;
- a filled title and a template are not held;
- a blank title on a step whose contract does not refuse it is not held.
Re-pin the PENDING case objectui#12030 left, rather than adding a second one.

Restart when

objectui#12030 has merged, so objectui resolves @objectstack/spec 18.

Read fresh. objectui#12030 has landed.

priority:p3. Today a blank Notify title is sent, and the server's refusal then shows with its path (nodes.N.config.title). Nothing is stored wrong and nothing is lost. The ask moves the stop earlier, matching how a missing title is already held.
target:v18. The refusal is new in spec 18.
Scope as filed: hold exactly what the flow parse refuses, no stricter. A template is not held. Pins in en and zh, and re-pin the PENDING case.

The parse is read lazily, once per call. So the hold is never stricter than the contract. Measured predicate (A2): spec 18.0.0-next.0 refuses a Notify title at nodes.N.config.title when it is a string empty after JS trim (empty, spaces, tab, newline, NBSP are refused; zero-width space and padded text are accepted). That is the spec's NON_BLANK_STRING rule, which is not exported, so A3 holds only partly: the parse supplies the refusal, and a cited blank test sorts unfinished from wrong. The PENDING case was re-pinned (en and zh held).

Review: ACCEPT — objectui PR #12367 · `domain:ui` seat 2 · `session_01XVp19E1MYUTFM3dnkwz8gB` · 2026-10-14T11:18Z

Reviewed on GitHub at head 9063f689dd, against the card and triage's grade 6162004382, not against the dev's report.

Shape: the PR is a draft against main, and its body opens Fixes #12343 (the only closing keyword), then Clause-②: no. The governed sweep reads NOT governed, 131 lines.
No contract review owed: Clause-②: no holds. flowHeldEdit's signature and every app-shell export are unchanged; only which drafts are held changes. None of the three contract faces is touched, so this is CI plus the seat's own read.
The hold is no stricter than the contract, by construction. In metadataError.ts, heldInputOf holds a blank text only when FlowSchema.safeParse of the draft refuses at that input's own path (refusedAt). The parse runs lazily and once per call.
- So a blank Screen title, which its contract accepts, is still sent.
- A non-blank refused value, or a null, shows its refusal rather than being held.
- The dev measured the blank predicate against the installed spec 18.0.0-next.0: empty or whitespace, including NBSP, is refused; a zero-width space or padded text is accepted. isBlankText (trim() === '') matches it.
The card's pins are in metadataError.heldEdit-11786.test.ts. The PENDING case objectui#12030 left is re-pinned, not duplicated.
- A blank title is held in en and zh.
- Filled, {{ }}, template-in-place, null and blank-Screen controls are not held.
- The dev's ablation turned the two blank-title pins red.
Prose, checked sentence by sentence: .changeset/12343-hold-blank-notify-title.md (@object-ui/app-shell: patch). The patch round corrected its last sentence, which had named a single-brace {name} title as refused. The installed FlowSchema accepts that title, by the dev's measurement. It now names a null title, which is measured refused and pinned not-held. Every other sentence matches the diff.
CI at head: 30 success, 3 skipped, 0 failures. The earlier run on 8ed13a7 was cancelled by its successor and is not counted.
Not filed:
- The installed flow parse accepts a single-brace Notify title, while objectui#11824's dev measured NotifyConfigSchema alone refusing one. That reach is unmeasured, so it stays in the PR's Acceptance notes.
- A blank Notify message is now held too, through the same generic path. It is noted in the PR.

Next: pr_ready + automerge_enable.
