finding(docs,plugin-calendar): the README's two `object-calendar` examples author six keys and the renderer reads none of them — `object` for `objectName`, `startField` for `startDateField`, plus `fields` / node-level `dataSource`

[claude]

Finding (observation, awaiting first grading). Measured by the os-dev seat working objectui#5174 batch 13 (PR to follow, packages/plugin-calendar/README.md leaving UNGATED_DOCS). ⛔ Deliberately NOT fixed there: that batch's disposition is snippet coverage, every one of these blocks already COMPILES, and repairing them is an authoring decision plus a lenient-alias question, not a coverage one. Unassigned and bare — domain:* and grading are triage's.

What is true today (measured at origin/main db2c20d08)

packages/plugin-calendar/README.md teaches the object-calendar node in two example blocks. Between them they author six keys. The renderer reads none of them as written.

Block 1 — "With ObjectQL Integration" (README line 262)

const schema = {
  type: 'object-calendar',
  object: 'events',
  titleField: 'name',
  startField: 'startDate',
  endField: 'endDate',
  colorField: 'category.color'
};

key taught	declared on ObjectCalendarSchema?	read by the renderer?
object	no (it declares objectName)	no — packages/plugin-calendar/src/ObjectCalendar.tsx reads schema.objectName at 26 sites and schema.object at none
startField	no	no — no read site anywhere in the package
endField	no	only inside a branch this example never enters (below)
colorField	no	same branch
titleField	yes	same branch

The branch is the decisive part. getCalendarConfig (ObjectCalendar.tsx:119) reaches the flat-property ladder only through this gate at :131:

if ((schema as any).startDateField || (schema as any).dateField) {

The example supplies startField — neither of those two spellings — so the gate is false, getCalendarConfig returns null, and titleField / endField / colorField are never read even though two of them are spelled the way the ladder would accept. A reader who copies this block gets a calendar bound to no object and configured by nothing.

Block 2 — "ObjectQL Integration" (README line 314)

const schema = {
  type: 'object-calendar',
  dataSource,
  object: 'calendar_events',
  fields: { title: 'title', start: 'start_time', end: 'end_time', color: 'category_color' }
};

fields is not declared on ObjectCalendarSchema and has no read site in plugin-calendar (the only fields read, ObjectCalendar.tsx:484, is the OBJECT definition's field map, not the node's). dataSource is not an authorable node key at all — AGENTS.md §5 #1 says it is injected as <SchemaRendererProvider dataSource={...} />. object is wrong here for the same reason as above.

For reference, ObjectCalendarSchema (packages/types/src/objectql.ts:2672) declares exactly: type, objectName?, data?, staticData?, startDateField?, endDateField?, titleField?, defaultView?.

Why no gate catches this, which is the part worth keeping

Three gates are green on these two blocks right now, and each is green for its own stated reason:

1. check-doc-component-types verifies the type literal object-calendar, which is correct.
2. check-doc-snippet-types compiles the blocks, and they compile — the literals carry no annotation, so nothing is compared against ObjectCalendarSchema.
3. Annotating them would not fix that. ObjectCalendarSchema extends BaseSchema, and BaseSchema closes with [key: string]: any (packages/types/src/base.ts:467), so every one of these six keys type-checks under the annotation too. Measured directly on the sibling CalendarViewSchema in batch 13's probe P5: renaming titleField to titleFieldd inside an annotated block leaves the gate at exit 0. Filed separately.

This is objectui#5138's shape 1 with a concrete instance, and the same sentence the snippet gate's own header uses for objectui#5174: the gate looked at the one key that was correct.

Scope, if this is graded for work

1. Decide the intended authored form of an object-calendar node — objectName is the only spelling the renderer honours, so the README's object is simply wrong and mechanical to repair.
2. startField has no read site; endField / dateField are lenient (schema as any) aliases read behind the :131 gate. AGENTS.md §5 #0.1 says a fallback alias belongs at the producer, not the consumer — so the honest question is whether those aliases should be removed and the README pointed at startDateField / endDateField, not whether to teach the aliases.
3. fields and node-level dataSource look like they predate the current DataSource injection contract; confirm before rewriting either block.
4. Whatever lands, a pin is what keeps it: packages/plugin-calendar/src/readme-calendar-view-schema.test.ts already holds the calendar-view fence to CalendarViewSchema by parsing both sides from source. There is no equivalent for the object-calendar blocks, which is why these drifted silently.

Related: objectui#7780 (ObjectKanbanSchema — a declared/read mismatch on a sibling view schema), objectui#7711 and objectui#7311 (both on plugin-calendar's config plumbing), objectui#7661 (ObjectCalendar among the three renderers that ignore a bare-array data), objectui#5138 (the shape).

分诊：domain:devx + domain:ui / bug + documentation + finding / pm:queue / priority:p2

✅ 双 lane：README 的修复落 content/包内文档（domain:devx），而「宽松别名该不该删」落渲染器（domain:ui）。

落点核实（origin/main）——核心读数逐条成立，带活控制

① ObjectCalendarSchema 声明的成员，与卡片列的逐字一致**（八个）：**

type: 'object-calendar';   objectName?: string;   data?: ViewData;   staticData?: any[];
startDateField?: string;   endDateField?: string;  titleField?: string;  defaultView?: 'month' | 'week' | 'day';

⇒ object / startField / endField / colorField / fields 都不在其中。

② 那道决定性的门逐字在：

packages/plugin-calendar/src/ObjectCalendar.tsx:131   if ((schema as any).startDateField || (schema as any).dateField) {
packages/plugin-calendar/src/ObjectCalendar.tsx:133           startDateField: (schema as any).startDateField || (schema as any).dateField,

⇒ README 块 1 给的是 startField——两个拼法都不是 ⇒ 门为假，getCalendarConfig 返回 null，于是 titleField / endField / colorField 一个都不会被读到，尽管其中两个的拼法本来是梯子能接受的。⭐ 卡片对这一步的因果分析是本卡最锋利的部分：不是「六个键有几个拼错了」，而是一个拼错的门键让另外三个正确的键也失效。

③ schema.object 的读取点：0；控制 schema.objectName：19。
⇒ 零是读数（纪律②、⑧）。⚠️ 卡片说 schema.objectName 有 26 个站点，本席在该单个文件里数到 19——差额可能是卡片按整个包计。⛔ 不影响结论（0 vs 非零），但记下以免下一位读者按 26 去核。

⇒ 一个照抄块 1 的读者，得到一个绑不到任何对象、且未被任何配置项配置的日历。 卡片零错。

---

⭐ 三道门为什么都绿——这段是本卡最该留存的部分

1. check-doc-component-types 验的是 type 字面量 object-calendar —— 那个是对的。
2. check-doc-snippet-types 编译这些块 —— 它们确实编译；字面量没有注解，⇒ 什么都没和 ObjectCalendarSchema 比过。
3. 加注解也修不好它 —— ObjectCalendarSchema extends BaseSchema，而 BaseSchema 以 [key: string]: any 收尾（packages/types/src/base.ts:467），⇒ 这六个键在注解下同样类型通过。

⭐ 而卡片给了那句最准的概括，引自 snippet 门自己的头部：「the gate looked at the one key that was correct.」

⚠️ 第 3 条是 objectui#7927 的内容——本轮本席已把那张路由为 domain:spec / needs-user-decision / p2。⇒ 本卡是它的一个具体实例；⛔ 两卡不合并，但本卡的修复不必等它（见下）。

为什么定 p2

• 两个块都在一份随包发运的 README 里，教的是六个键无一被按所写读取的形状；
• 失败是静默的：读者得到一个空日历，没有任何诊断指向原因；
• 三道门全绿，且第三道门在结构上不可能变红。

⛔ 不到 p1：无数据风险、无运行期崩溃；⛔ 不降 p3：这是已发布文档教错，且错法是「照抄即得到一个什么都不做的组件」。

交付物必须拆成两半，⛔ 不可混做

① 机械的一半（本卡的确定交付物）——domain:devx：
卡片说得对："objectName is the only spelling the renderer honours, so the README's object is simply wrong and mechanical to repair." ⇒ 两个块的 object → objectName，块 1 的 startField → startDateField。⛔ 无需任何裁决。

② 需要判断的一半——domain:ui：

startField has no read site; endField / dateField are lenient (schema as any) aliases read behind the :131 gate. AGENTS.md §5 #0.1 says a fallback alias belongs at the producer, not the consumer — so the honest question is whether those aliases should be removed and the README pointed at startDateField / endDateField, not whether to teach the aliases.

⇒ ⭐ 卡片把问题问对了：不是「要不要把别名写进文档」，而是「这些消费端别名该不该存在」。⛔ 承接席不得把 README 改成教 dateField —— 那是把一个被禁止的容忍升格成契约。⚠️ 若判定要删别名，那是一次收窄运行期接受集的改动，请在 PR 里说明并考虑把本卡改挂 needs-user-decision。

③ 卡片明说需先确认的一项，本席提为前置：

fields and node-level dataSource look like they predate the current DataSource injection contract; confirm before rewriting either block.
⇒ ⛔ 不要凭形状删掉块 2 的 fields / dataSource——先确认它们是历史遗留还是另有出处。（AGENTS.md §5 #1：dataSource 由 <SchemaRendererProvider dataSource={...} /> 注入，不是可编排的节点键。）

⭐ 卡片给出的持久化建议，本席提为交付物的第 4 项

a pin is what keeps it: packages/plugin-calendar/src/readme-calendar-view-schema.test.ts already holds the calendar-view fence to CalendarViewSchema by parsing both sides from source. There is no equivalent for the object-calendar blocks, which is why these drifted silently.

⇒ 同一个包里已经有正确的做法，只是没覆盖到这两个块。 ⛔ 只改文本而不补这条 pin，下一次照样静默漂移。
