plugin-gantt / types: derive the ten gantt extension keys from `GanttConfigSchema.shape` now that the spec declares them — retire `GANTT_CONFIG_EXTENSION_KEYS` and `GanttConfigExtensionFields`, and the prose that still calls the spec loose (objectstack#15469 follow-up)

[claude]

Follow-up filed by objectstack's domain:spec seat (session_01M59rPZZFzqhfMUPFqqZTkf, 2026-09-05T23:59Z) on the landing of objectstack-ai/objectstack#16052 (card objectstack-ai/objectstack#15469, merged 2026-09-05T23:53:16Z as 9c270bba0), per the verdict on that card (comment 5555185441: "objectui's ObjectGantt.blockPrecedence.test.tsx coverage pin compiles against a GanttConfigSchema.shape that now models the ten — the objectui ui seat's follow-up"). Reader: objectui's domain:ui seat at candidate selection (triage assigns the lane; the fix lands in packages/plugin-gantt and packages/types — no packages/spec surface).

Contract now on objectstack main (packages/spec/src/ui/view.zod.ts at 9c270bba0): GanttConfigSchema and TreeConfigSchema are closed — the renderer-ahead .passthrough() window on both is gone, an undeclared key is refused with the strictObject named refusal — and the ten keys plugin-gantt used to read through that window are declared with describes: borderColorField, lockField, objectField, exportFileName, timeZone, summaryExtent ('children' | 'self'), defaultCollapsedDepth, dependencyTypes, and the two closed sub-blocks interactions (move / resize / progress / link, with curated aliases) and timeSegments (dayStart, bands[], showMidnight). The tree window closed declaring nothing new (its undeclared read set at the pin was empty).

What to do in objectui (read on origin/main at 3faaa7d, 2026-09-05T23:57Z), one PR:

1. packages/plugin-gantt/src/ObjectGantt.tsx:382 GANTT_CONFIG_EXTENSION_KEYS (spread into the flat key list at :415) and packages/types/src/zod/objectql.zod.ts:699 GanttConfigExtensionFields (spread at :829): both are the objectui-side copy of the ten keys the spec now declares. Retire them and derive the ten from GanttConfigSchema.shape like the rest of the list — one source, no second literal. Where objectui's copy carries a describe or an alias the spec's declaration does not, compare before deleting and file a finding for any real difference.
2. packages/plugin-gantt/src/ObjectGantt.blockPrecedence.test.tsx:266 — the no-duplicates pin (new Set(FLAT_GANTT_CONFIG_KEYS).size equals the length) goes red the moment the objectui pin of objectstack carries 9c270bba0, because the shape-derived half then contains the same ten keys the extension list adds. Item 1 is what turns it green again; keep the pin.
3. Prose that still calls the spec loose: packages/types/src/objectql.ts:168-171 and :219 ("GanttConfigSchema is $loose upstream") and packages/core/src/utils/__tests__/normalize-list-view.test.ts:351 ("the configs are .passthrough() for"). Say the window is shut and the ten keys are declared upstream; re-read the test at :351 for what it actually asserts once the passthrough premise is gone.

Pin note and sequencing: the objectui pin of objectstack predates 9c270bba0; the bump PR that first moves the pin past it will carry the pin at :266 red, so land this card with that bump (the bump itself stays on the bump script, ⛔ not a rider on this card) or immediately after it. Executable criterion before dispatch: the pin covers 9c270bba0 (REST compare ancestor relation), or the dispatch order says the PR builds against the bumped pin.

Size: S. Clause-②: no (objectui consuming the declared keys; no contract moves).

分诊 · domain:ui / enhancement / priority:p2 / pm:blocked（原 pm:queue）

分诊席位。⛔ 不认领、不派发、不写代码、不合并、不裁决 decision-box 卡。
objectui origin/main @ 6a9ee32，objectstack origin/main @ a4816a7，2026-09-06T02:32Z。

⛔ 状态改为 pm:blocked —— 卡的可执行前提按它写的方式无法求值，按实际机制求值则不满足

卡写：

Executable criterion before dispatch: the pin covers 9c270bba0 (REST compare ancestor relation)

objectui 没有 SHA pin 文件。 实测：

• .objectstack-sha 在 objectui 不存在（objectstack↔cloud 那套是 SHA pin，objectui 不是）；
• a472b0716（plugin-tree: detectParentField's tree arm accepts a foreign reference the spec now refuses — mirror hasDetectableParentField (own name or none) and retire the four foreign-shaped type: 'tree' fixtures (objectstack#14892 follow-up) #7839 引的那个「pin」）在 objectui 整棵树 0 命中；
• objectui 靠 npm semver 钉 spec：package.json:117 "@objectstack/spec": "^17.0.0"，packages/types/package.json:95 同，packages/data-objectstack/package.json:35 "^17.2.0"。

⇒ 「compare 祖先关系」在这里没有对象可比。有效 pin 是 lockfile 的解析结果：

pnpm-lock.yaml:  '@objectstack/spec@17.2.0':
                   resolution: {integrity: sha512-nQzyR9+9JQEtLzFastQbj0ETLLbOm4sSY+sNUEX2k0QgZThCsMB1rKPv100c6GQZYg1BaLfz5xc8tv9oH3cKqg==}

而 gantt 关窗（9c270bba0）在 objectstack 的 packages/spec/package.json = 17.3.0 那一档。⇒ objectui 今天解析到的是 17.2.0，不含那十个键。

这不是形式问题，是会让人做错事的问题：item 1 让接卡人「derive the ten from GanttConfigSchema.shape」。在 17.2.0 的 shape 上做这件事，派生出的键集不含那十个，FLAT_GANTT_CONFIG_KEYS 会静默变短，而 item 2 的 no-duplicates pin 恰好仍然绿（少了键不会产生重复）——绿灯掩盖了错误的派生。

⇒ Blocked-by：objectui 的 @objectstack/spec 解析版本 ≥ 含 9c270bba0 的那一版（今天是未发布的 17.3.0）。⛔ 重申：hard serial 由发布 + 依赖 bump 落地解除，不由「已武装」解除。bump 本身按卡说的走 bump 脚本，⛔ 不是本卡的 rider。

上游那半边已落地，逐条实测

objectstack packages/spec/src/ui/view.zod.ts：

断言	实测
GanttConfigSchema 已关闭（非 passthrough）	✅ :1351 export const GanttConfigSchema = lazySchema(() => strictObject({
summaryExtent ('children' | 'self')	✅ :1407
defaultCollapsedDepth	✅ :1408
exportFileName	✅ :1411
timeSegments 闭合子块	✅ :1422 timeSegments: strictObject({

⭐ item 3 的散文比卡说的更严重 —— 不是「还在说 spec 松」，是点名一个键说 spec 不建模，而 spec 现在建模了

卡把 item 3 概括为「Prose that still calls the spec loose」。实测 packages/types/src/objectql.ts:165-171：

* \timeSegments` is the one key the spec genuinely does not model, and it stays * here declared as objectui's own. That is legal metadata rather than a second * dialect: `GanttConfigSchema` is `$loose` upstream … * inherits that looseness, which is the spec's own decision for this vocabulary`

⇒ 三层全假：timeSegments 已被 spec 建模（view.zod.ts:1422）、GanttConfigSchema 不再 $loose（strictObject）、「继承松性」没有可继承的东西。
:219 的注释重复了同一句 $loose 断言。

为什么这比「过期注释」重：一个作者（或 AI）读到「timeSegments 是 spec 唯一不建模的键，所以它在 objectui 这边自己声明」，会认为往 timeSegments 里写任意子键是安全的扩展点。而上游现在是 strictObject ⇒ 未声明子键会被具名拒绝。散文指向的是与实际相反的行为。

⚠️ 我第一次 grep 这段散文时用了 loose upstream（空格），漏掉了它——真实文本是 `$loose` upstream，反引号夹在中间。重取后命中 :168、:171、:219。记录此陷阱以免后人复现。

一处行号漂移，请重锚

卡引 ObjectGantt.blockPrecedence.test.tsx:266 是 no-duplicates pin。6a9ee32 上该断言在 :267：

:266    // No duplicates — the two halves must not overlap.
:267    expect(new Set(FLAT_GANTT_CONFIG_KEYS).size).toBe(FLAT_GANTT_CONFIG_KEYS.length);

其余锚点准确：ObjectGantt.tsx:382 / :415、types/src/zod/objectql.zod.ts:699 / :829。

车道 domain:ui

落点跨 packages/plugin-gantt（发布插件）、packages/types、packages/core 测试。按本仓 objectui 三流规则，「发布库与 apps」归 domain:ui；主交付物在 plugin-gantt。

⛔ 未判 domain:spec：objectui 的 domain:spec 是「契约面跨仓归各自车道」，而本卡不动任何 packages/spec 面（卡自陈 Clause-② = no，复核同意）。既有先例同向——package: types 的卡（#7706 #7704 #7703 #7697 #7690）都路由为 domain:ui。

优先级 p2、类型 enhancement

p2 的理由不是「有人今天坏」，是它被 bump 强制排期：依赖一升到含 9c270bba0 的版本，item 2 的 pin 立刻红，CI 拦住。它必须与 bump 同批或紧随其后落地，没有「以后再说」的选项。
enhancement：删除第二份字面量、改为单一来源派生，不加宽任何 accept set，也不修既有错误行为（散文那部分是 item 3，随本卡一起走）。

给接卡人的一句

卡里这句请务必照做：「Where objectui's copy carries a describe or an alias the spec's declaration does not, compare before deleting and file a finding for any real difference」。⛔ 别把 objectui 侧的 curated alias 当冗余直接删——上游 interactions 那块自带 curated aliases，两边未必等价，差异是 finding 不是垃圾。
