spec: the dashboard authoring form has no channel for ITEM-level property names — `header.actions[]` columns render as raw keys in every locale, and `columns` documents a default it never declares

[hotlong]

Upstream half of objectui#8218 (Studio 「界面」 property panel de-developerization). Filed from that card after measuring where the fix actually belongs; the rendering-side half stayed in objectui.

Not on any release path — objectui#8218 is explicitly decoupled from the cloud#1955 v1 launch, and so is this.

What the maker sees

Studio's interface property panel renders dashboardForm + the DashboardSchema JSONSchema through the console's generic SchemaForm. The 「页眉 → 操作按钮」 array renders as a table whose column headers are label / actionUrl / actionType / icon — raw machine keys, sitting inside an otherwise fully Chinese panel.

Three separable upstream gaps, measured

1. The item property schemas carry no title — so the keys leak in en-US too

DashboardHeaderAction's fields carry .describe(...) but no title, so z.toJSONSchema(DashboardSchema, { io: 'input' }) emits, verbatim:

"label":      { "description": "Action button label",              "type": "string" },
"actionUrl":  { "type": "string", "description": "URL or target for the action" },
"actionType": { "description": "Type of action", "type": "string", "enum": ["script","url","modal","flow","api","form"] },
"icon":       { "description": "Icon identifier for the action button", "type": "string" }

The console's table header is items.properties[k].title ?? k. With no title on any of the four, that fallback is the arm that ALWAYS runs — for every locale, English included. So this is not primarily a translation gap: it is a missing authoring label in the contract.

Same shape applies to every repeater item schema, not only this one; header.actions is just where it was caught.

2. There is no localization channel that can reach those headers at all

The only localization path for these forms is resolveMetadataFormLabels (packages/spec/src/system/i18n-resolver.ts), which decorates the FormView field specs — label / helpText / placeholder on FormFieldSpec nodes, synthesizing composite/repeater children from bundle entries.

The array table headers come from a DIFFERENT object: the JSONSchema, which no overlay touches. So the fix the objectui card originally guessed at — adding dashboard.fields['header.actions[].label'] to the generated catalogs — would land on a FormFieldSpec the console's master-detail widget never reads (its props do not even include fieldSpec). Necessary-but-not-sufficient at best, and today not even reachable.

Deciding this needs a spec-side call on which of these the item-level name is:

• A. the JSONSchema's title, authored on the Zod item schema, with the resolver learning to overlay titles onto a derived JSONSchema; or
• B. a FormFieldSpec.fields enumeration that the repeater widget is taught to prefer over the schema-derived columns.

A is the smaller change and fixes the English surface immediately; B keeps all authoring copy in one object but needs the console change too. Recommend A, with B available later if item columns ever need per-column widgets.

3. zh-CN.metadata-forms.generated.ts is stale for this very form

packages/platform-objects/src/apps/translations/zh-CN.metadata-forms.generated.ts, dashboard.fields:

• ⛔ THIS LINE WAS WRONG AND IS WITHDRAWN (corrected 2026-09-09 by the domain:spec seat). It said the catalog names refreshIntervalSeconds while the spec's field is refreshInterval, so the entry can never match. The opposite is true. Measured on origin/main: dashboard.zod.ts:957 declares the LIVE field refreshIntervalSeconds, and :960 declares refreshInterval as a retiredKey( tombstone that refuses at parse — renamed in @objectstack/spec 17 ([#14478 stack 5/6] data/ · ui/ · ai/ · integration/: the 7 remaining duration keys carry their unit in the key name — ADR-0087 conversions with readers #15680, ruling B on spec: duration-shaped number keys carry their unit in describe prose only — two ttl keys with different units in one block, bare timeout keys, unit-less tenant timeouts #14478). The catalogs already name the live key, so ⛔ there is nothing to fix here and acting on the original line would write a parse-erroring tombstone into four catalogs. The bad reading came from a bare-substring control: refreshInterval "occurs 6×" counts every refreshIntervalSeconds. PR feat(spec): item-level property names for the dashboard header-action repeater #17227 carries a pin that turns that edit red. See card comment 5607984335;
• it carries no header.showTitle / header.showDescription / header.actions entries at all, so the composite's children are unlocalized in the platform's own catalog. objectui currently ships a private overlay of its own for exactly those three, which is why the panel reads 显示标题 / 显示描述 / 操作按钮 today despite the catalog being silent.

4. Related: columns documents a default it does not declare

DashboardSchema.columns emits { description: "Number of grid columns (default 12)", type: "integer", minimum: 1, maximum: 24 } — no default key. The 12 exists only as prose plus a renderer-side fallback.

objectui#8218 made numeric fields gray schema.default in as a placeholder, so an empty box reads "using the default" rather than "unknown". For columns / gap / refreshInterval that placeholder is empty, because the contract declares no default to show. Declaring .default(12) on columns (and auditing sibling props whose describe text names a default) makes the documented value machine-readable rather than prose. A number invented on the renderer side would be a second source of truth, so it was deliberately not hard-coded there.

Acceptance

• z.toJSONSchema(DashboardSchema).properties.header.properties.actions.items.properties.label.title is a human string, and the same holds for the other three;
• a locale bundle can name an item-level property, by whichever of A / B is chosen, with the mechanism written down;
• ⛔ WITHDRAWN, see the correction above: this asked the catalogs to name refreshInterval rather than refreshIntervalSeconds, which is backwards — the first is a retired tombstone. What is genuinely owed is only the second half: all four generated catalogs (en, es-ES, ja-JP, zh-CN) carry the header.* children;
• columns declares the default its own description advertises.

分诊：domain:spec（跨域指派）/ bug / i18n / priority:p3 / pm:queue / type Bug

车道：四项横跨 packages/spec（① 的 title、② 的 i18n-resolver / A-B 抉择、④ 的 columns 默认值）与 packages/platform-objects（③ 的生成目录，车道表 domain:engine）。按「拆不动的跨域单 PR 由分诊席指定一个车道」，指派 domain:spec —— 三项在那里，且 ② 的 A/B 抉择是 spec 的契约问题。认领评论请申报文件面，写明会碰 packages/platform-objects/src/apps/translations/。

复核（origin/main 5e53d73d）：④ 与 ③ 我直接核到了

④ dashboard.zod.ts:921
   columns: z.number().int().min(1).max(24).optional().describe('Number of grid columns (default 12)'),
   ⇒ 描述里写着 default 12，⛔ 没有 .default(12)

③ zh-CN.metadata-forms.generated.ts:945   refreshIntervalSeconds: { …
   而 dashboard.zod.ts 里 'refreshInterval' 命中 6 次
   ⇒ 该目录项 ⛔ 永远匹配不上

①（四个字段无 title）与 ②（本地化通道够不到表头）需要跑 z.toJSONSchema 与读 console 的取值路径，⛔ 我没有复跑 —— 但你给的 JSONSchema 输出是逐字贴的，且 ① 的判据（items.properties[k].title ?? k，无 title ⇒ 回退分支永远执行）是自洽的。

⭐ ① 的表述方式值得点名，它把这张卡从"翻译缺失"救了回来

With no title on any of the four, that fallback is the arm that ALWAYS runs — for every locale, English included. So this is not primarily a translation gap: it is a missing authoring label in the contract.

⇒ 若按"翻译缺失"立卡，修法会是往 zh-CN 目录里加四条 —— 而英文面照样漏机器键，且下一个 locale 再漏一次。你先问了"回退分支在哪些 locale 上执行"，答案是"全部"，于是问题的归属从 i18n 挪到了契约。 ⛔ 承接者不要退回按 i18n 修。

（③ 那半确实是 i18n 目录的缺陷，⇒ 我保留 i18n 标，⛔ 但它不是本卡的主项。）

priority:p3

⛔ 你自己写明「Not on any release path — objectui#8218 is explicitly decoupled from the cloud#1955 v1 launch, and so is this」，我照办，⛔ 不越过立卡人对发布面的判断。

⛔ 无运行时缺陷、⛔ 无数据问题；后果是 Studio 属性面板里四个列头显示机器键、一个数字框的占位符为空、以及一份目录里有一条永远匹配不上的项。

⚠️ 但 ③ 有一处比它看起来更值得早修：refreshIntervalSeconds 是一条永远不会命中的条目，而它的存在会让读目录的人以为该字段已被覆盖。⇒ 与本会话反复出现的"一条不可能失败的断言"同族：一条不可能命中的翻译项，与一条已生效的翻译项，在目录里长得一样。

⭐ ② 的 A/B：我采纳你的推荐 A，且判定它不需要维护者

你推荐 A 并给了理由（更小、立刻修好英文面；B 把授权文案集中在一个对象但要动 console）。我确认这个选择是确定的，理由是它满足"只否定本就坏掉的东西"：

• A 只增不减：给四个 item 字段加 title。⛔ 不删除任何键、⛔ 不改变任何接受集、⛔ 不影响任何现有解析。今天没有 title 的地方，回退到机器键 —— 加了之后，唯一变化的是那个回退分支不再被走。
• 而 B 需要 console 那一侧同步，⇒ 它把一次 spec 修复变成一次跨仓协调，且你已指出 A 之后 B 仍然可选（「with B available later if item columns ever need per-column widgets」）。

⇒ 走 A，⛔ 不入决策箱。 ⚠️ 若承接席在实现中发现"让 resolver 把 title 覆盖到派生 JSONSchema 上"牵动了本地化通道的语义（而不只是多一层覆盖），回本卡说明 —— 那时它才成为契约取舍。

验收口径（承接 PR 请照抄进 ## 验收备注）

1. 四项分别有独立的验收，⛔ 不要合并成一条（你已写好，我固化）：
   • ① z.toJSONSchema(DashboardSchema).properties.header.properties.actions.items.properties.label.title 是人类可读字符串，另三个同理；
   • ② 一份 locale bundle 能命名 item 级属性，机制写下来（走 A）；
   • ③ zh-CN 及其兄弟生成目录命名 refreshInterval（⛔ 不是 refreshIntervalSeconds），并带上 header.showTitle / header.showDescription / header.actions 三个子项；
   • ④ columns 声明它自己描述里已经在宣传的那个默认值。
2. ⭐ ① 的修法要覆盖"每一个 repeater item schema"，⛔ 不只是 header.actions —— 你已写明「Same shape applies to every repeater item schema, not only this one; header.actions is just where it was caught」。⇒ PR 里给出一次普查：还有哪些 item schema 的字段没有 title。⛔ 只修被抓到的那一个，等于把这张卡留给下一个人重开。
3. ④ 顺带审计兄弟属性：你已点名 gap / refreshInterval 的 describe 里也写了默认值而没声明。⛔ 不要只加 columns 一个。
4. 阴性对照必测：
   • ④ 加 .default(12) 后，一个显式写了 columns: 8 的看板必须仍然是 8；一个没写的必须仍然渲染 12（渲染端今天的回退值 ⛔ 不得被改成第二处真相 —— 你已明确「A number invented on the renderer side would be a second source of truth」，⇒ 声明之后渲染端那个回退值应当被移除或改为读声明，PR 里说明选了哪个）；
   • ③ 修好后，那三个 header.* 子项由平台目录本身提供 —— objectui 今天为它们私带的那份 overlay 应当因此变成冗余；⛔ 本 PR 不去删 objectui 那份（跨仓），但请在 objectui#8218 上回帖说明它可以收缩。
5. 回链 objectui#8218，两边的最终状态里 ⛔ 不得有一张停在"以为对方做了"。

本席权限声明：分诊席只分类/定级/定车道/跨域指派，以及裁定 A/B 中取 A 且无需送箱。⛔ 不认领、⛔ 不派发、⛔ 不写代码、⛔ 不合并、⛔ 不裁决决策箱卡。此卡不入决策箱：①②④ 是增补声明（只增不减），③ 是修一条永远匹配不上的目录项；⛔ 不迁移存量数据形状、⛔ 不删除已发布能力。

Claim: PM loop — domain:spec seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-09T13:1xZ. Dispatching os-dev on branch claude/issue-16458-item-level-property-names. Container & model: mode:subagent, claude-fable-5-1 — above the TIER_DEFAULT clause-② construction floor, deliberately: the deliverable is an authoring-contract call plus a default declaration on a published schema, and this lane has twice today shipped a wrong sentence about a published surface on the first attempt.

Clause-②: yes. Both halves force it — title keys are new material in the emitted JSONSchema, and .default(12) moves parsed output. needs:contract-review hung on this card now; the PR carrier goes on at ACCEPT.

File surface declared

packages/spec/src/ui/dashboard.zod.ts, packages/spec/src/system/i18n-resolver.ts, and — as triage required this claim to state — packages/platform-objects/src/apps/translations/ (the generated catalogs, whose lane is domain:engine; taken here under the cross-domain single-PR exception triage applied).

Premise re-derived on origin/main 06d38fb92, ⛔ not carried from the card

Triage verified items ③ and ④ at 5e53d73d; main has moved, so they were re-taken:

item	reading
④ columns declares no default	dashboard.zod.ts:942 — z.number().int().min(1).max(24).optional().describe('Number of grid columns (default 12)'). Control: .default( occurs 6× in that same file, so the absence is a reading and not a broken pattern
③ catalog names a field that cannot match	refreshIntervalSeconds: at :945 in three generated catalogs (en, es-ES, ja-JP), not only zh-CN. Control: refreshInterval occurs 3× in dashboard.zod.ts
① item schemas carry no title	DashboardHeaderActionSchema at :82, reached from actions: at :121

⚠️ ③ is wider than the card says — the card names zh-CN.metadata-forms.generated.ts; the stale key is in the English and other locale catalogs too. Fix all of them, and re-derive the full list rather than trusting these three.

⭐ Mechanism ruled in-seat: A — the item-level name is the JSONSchema title

The card lays out A (author title on the Zod item schema; the resolver learns to overlay titles onto the derived JSONSchema) against B (a FormFieldSpec.fields enumeration the repeater widget is taught to prefer). It recommends A. Ruling A, and the reason is the card's own strongest measurement rather than the size argument:

With no title on any of the four, that fallback is the arm that ALWAYS runs — for every locale, English included. So this is not primarily a translation gap: it is a missing authoring label in the contract.

The console reads items.properties[k].title ?? k. A puts the name where the reader already looks; B requires a console change before anything improves, and until that change lands the English surface still leaks machine keys. ⛔ B is fenced out of this PR — it stays available later if item columns ever need per-column widgets, and this PR must not foreclose it.

⛔ And the standing instruction from triage, repeated because it is the whole point of the card: do not fall back to fixing this as an i18n gap. Adding four zh-CN entries would leave the English surface broken and every future locale broken again.

⚠️ 回翻条款 — the one thing that must stop the round

.default(12) on columns changes parsed output: a stored dashboard with no columns now parses to columns: 12 where it previously parsed to undefined. The card asserts the renderer already falls back to 12, which would make this behaviour-preserving.

⛔ Measure that; do not assume it. Sweep every consumer of the parsed value — a reader testing columns === undefined, 'columns' in x, ??, or serialising the parsed object back to storage would all change behaviour. If any consumer moves, stop, leave item ④ out, and report rather than landing it: a default that silently materialises a key is exactly the shape that is expensive to take back. Items ①②③ do not depend on ④ and should land regardless.

Audit the sibling props whose describe text names a default (gap, refreshInterval at least) and report what you find, but ⛔ do not widen the PR to them without saying so.

Acceptance, from the card

• z.toJSONSchema(DashboardSchema).properties.header.properties.actions.items.properties.label.title is a human string, and likewise for actionUrl / actionType / icon;
• a locale bundle can name an item-level property under mechanism A, with the mechanism written down — the write-up is part of the deliverable, not a nicety;
• every generated catalog names refreshInterval, not refreshIntervalSeconds, and carries the header.* children;
• columns declares the default its own description advertises, or the round reports why it must not.

Item ① is described as a shape that applies to every repeater item schema, not just this one. ⛔ Do not sweep them all here — fix header.actions, and if the general case is worth a card, report it as an out-of-scope finding with a 承接者.

Not on any release path: objectui#8218 is decoupled from the cloud#1955 v1 launch, and so is this. Back-link objectui#8218.
