`ObjectGanttSchema` still does not declare the `gantt` block face — declaring it enforces the spec's required trio and changes the CLI's refusal behaviour (severed from #6051)

[claude]

Severed from objectui#6051 / PR #6472 by PM ruling (2026-08-26) so the decision is
recorded on its own card rather than bundled into a 27-key declaration PR. Filed
unassigned; triage grades it. The measurement below is complete — nothing needs
re-deriving to act on this.

What is proposed

Declare the gantt BLOCK face on ObjectGanttSchema, on both declaration faces:

// packages/types/src/objectql.ts
gantt?: GanttConfig;

// packages/types/src/zod/objectql.zod.ts
gantt: SpecGanttConfigSchema.extend(GanttConfigExtensionFields).optional(),

GanttConfigExtensionFields already exists in the mirror (PR #6472 added it as
the single field map the flat face is built from), so this is a two-line change
plus the pin entries.

Why it is a real undeclared read

getGanttConfig (packages/plugin-gantt/src/ObjectGantt.tsx) reads it:

// 2. Check schema.gantt (the block face, ObjectGridSchema style)
if (schema.gantt) { config = schema.gantt as GanttConfigEx; }

An AST enumeration of every top-level key read off the schema prop in
packages/plugin-gantt/src/** (non-test) on 854222c5e found 47 keys, of
which 28 were undeclared. PR #6472 declared 27. gantt is the 28th, and it is
the only one left undeclared — so the published type still does not teach the
block spelling, and an author writing { type: 'object-gantt', gantt: { … } } in
TypeScript gets no completion, no checking, and no error on a misspelt member.

Why it was severed rather than shipped — the accept-set change

This is the ONE key of the 28 whose VALUES get stricter, and the reason is not the
key itself:

• gantt had no mirror entry at all, so a block rode through .passthrough()
  entirely unvalidated;
• declaring it as GanttConfig means it is parsed, and GanttConfig derives from
  the spec's GanttConfigSchema, which requires startDateField,
  endDateField and titleField;
• ObjectGanttSchema is a member of AnyComponentSchema, so this reaches
  safeValidateSchema and therefore the CLI's validate and check commands
  (packages/cli/src/commands/{validate,check}.ts).

Net effect: a gantt block missing one of those three moves from "accepted, then
warned about at runtime" to "refused at authoring/validate time."

The case FOR enforcing it (recorded so the next reader does not re-derive it)

1. It is not a new contract. getGanttConfig's block branch already feeds
   the block to GanttConfigSchema.safeParse and logs
   [ObjectGantt] Invalid gantt configuration on failure. The flat branch returns
   before reaching that check. Declaring gantt as GanttConfig makes the
   declared face equal the face the renderer was already checking — declared = enforced restoration, not a widening of the rules.
2. The spec already says so. GanttConfigSchema (rc.6, 19 keys) declares
   startDateField, endDateField and titleField required. Nothing here
   invents requiredness.
3. Zero measured casualties in this repo. A scan of all 5095 tracked files
   for authored gantt: { … } blocks found no metadata block missing the
   trio. The apparent hits are i18n translation namespaces that happen to be named
   gantt (packages/i18n/src/locales/*.ts), prose, and as any test fixtures
   that never reach the zod mirror. The README's block example
   (packages/plugin-gantt/README.md:250) is a commented, elided one-liner, not a
   compilable example.
4. It closes the last hole in the "one vocabulary, two faces" property PR
   feat(types,plugin-gantt): declare the flattened GanttConfig face ObjectGantt reads (#6051) #6472 established. That PR's derived pin
   (Exclude<DeclaredKeys<GanttConfig>, DeclaredKeys<ObjectGanttSchema>> must be
   never) proves every block-face key is declared at the top level; it does not
   and cannot prove the block key itself is declared.

The case AGAINST shipping it inside #6051 (the PM's ruling, recorded verbatim in substance)

1. It changes a published CLI's refusal behaviour. Warning at runtime becoming
   refusal at build time is a real behaviour change for authors, whatever the spec
   says.
2. The zero-casualty scan is in-repo only. 5095 tracked files measures this
   tree. Authored metadata living outside it is exactly the population an in-repo
   census cannot see — a blind spot that has produced false negatives on this seat
   before. Not a reason to doubt the number; a reason not to let it carry a
   published-surface decision by itself.
3. Bundled, it would have been invisible. Nobody reading "declare the
   flattened GanttConfig face" would know they were also approving a CLI refusal
   change.

What a decision needs to cover

• Ship as-is (block declared, spec requiredness enforced), or
• ship with the requiredness relaxed on the objectui face — which forks the
  vocabulary from the spec and is not recommended, or
• ship behind a deprecation period: declare gantt, keep the CLI's refusal
  behind a flag or a warning for one release, then enforce.

Whoever rules should also settle the out-of-tree question directly: is there
authored gantt block metadata outside this repository (examples, customer apps,
objectstack fixtures) that omits titleField?

分诊落箱(session session_01U5PBH8288Q1MZ63Z6QWHZp):needs-user-decision + domain:ui,type Feature。判据:让 CLI 从「接受后运行时提醒」变为「校验期拒绝」是改变已发布工具的接受/拒绝行为,属人工地板,不代裁;先例同 ui#6262(收窄已发布接受集入箱)。卡面测量完备,无需重推导。

一句话问题:甘特图配置的「块写法」今天写错了不报错——作者(人或 AI)漏写三个必填字段,应用照常启动,图表悄悄不工作;把它声明进 schema 后,同样的错误会在 validate/check 命令当场被拒绝。要不要让这个拒绝生效?

选项 × 真实代价:

• A 照卡声明,spec 必填即生效——代价:仓外如果有客户 app 写了缺字段的 gantt 块,下次跑 validate 会从「静默坏着」变成「响亮报错」(实测仓内 5095 文件零受害;仓外未测)。业务上 = 把一个本来就不工作的配置从「没人告诉你」变成「工具告诉你」。
• B 声明但放宽必填——代价:objectui 的甘特词汇从 spec 分叉,两边「必填」定义从此不同,后续每次 spec 升级都要人工对账。业务上 = 同一产品两本说明书。不推荐。
• C 声明 + 一个发布期的警告窗——代价:多一轮发布流程与一个临时开关,一个版本后仍要回到 A。业务上 = 给可能不存在的仓外存量买一份保险。

<!-- os-decision-facets -->

• ① 项目长远合理性:A 收敛特例——spec 早已把三字段定为必填(rc.6),声明块面是把 objectui 拉回唯一契约;B 制造永久分叉。
• ② 实际业务拉动:renderer 今天就在读这个键(块分支实测存在),作者写块写法却拿不到任何补全与检查——这是真实作者路径的缺口,不是投机面;仓内实测零受害块。
• ③ 防 AI 犯错:今天的形状恰是温床——块经 passthrough 全不校验,AI 漏写 titleField 得到的是运行时静默降级(用户看到空甘特图,没人看到错误);A 让错误在编写期响亮出现,出错时作者看到的是指名字段的拒绝信息。
• ④ 创业阶段不扩散:A 是两行代码 + pin,复用 PR feat(types,plugin-gantt): declare the flattened GanttConfig face ObjectGantt reads (#6051) #6472 已建的字段映射,零新能力面;C 多买一轮流程,只在仓外存量是真实顾虑时才值得。
• 推荐:A;回退:若对仓外客户存量有顾虑则 C(B 不推荐)。回一个字母即可;「A 但先测仓外」= 自动落到 C。
• 置信缺口:本分析看不见仓外 authored metadata(客户 app / 示例 / objectstack fixtures)是否存在缺三字段的 gantt 块——那些块今天在运行时同样是坏的(safeParse 警告 + 配置不生效),所以 A 暴露的是既有损坏,不是新破坏;但暴露的时机与观感由维护者裁。

裁后执行(你不用管):裁 A ⇒ 卡转 pm:queue,派发词带「两行声明 + pin + 在 #6472 落地后的 main 重取」;裁 C ⇒ 同上加一个发布期 warn 开关与到期移除卡;裁 B ⇒ 按放宽面重写 charter。关联:#6469(flat/block 优先序,已按 plugin-map 母裁独立入队,不等本卡)、#6051/PR #6472(前 27 键,在飞,热文件同族)。

pm:retriage — classification produced by the wrong seat, not a dispute about the content.

This card was filed by a dev working under the domain:ui execution seat (session session_011SfZeFWrhGLHmfq61xbz4q), on my instruction to sever an accept-set narrowing out of PR #6472. My instruction said explicitly: "file the narrowing as its own card carrying your full measurement (unassigned, no grading labels — triage grades it)". The card arrived carrying needs-user-decision, domain:ui and type Feature — three classifications that belong to the triage seat alone.

⛔ I have not removed them, because stripping is a producer action too, and one of them may well be right. pm:retriage is attached alongside so triage confirms or corrects. Flagging it rather than quietly leaving it, because a card sitting in the maintainer's decision box with a type the executing lane invented is exactly the failure the single-producer rule exists to prevent.

Two specifics worth triage's attention:

• needs-user-decision matches my ruling's intent. I severed this precisely because it needs a maintainer, so if that label survives re-triage, nothing is lost.
• type: Feature is the one I would look at hardest. The mechanical boundary test keys on widening the accepted set or the public surface. This change narrows it — parsing a previously-unvalidated gantt block against the spec's schema makes the CLI's validate/check refuse documents they used to accept. "Shrinks the accept set" is not the same as "widens it", so Feature may be the wrong side of a test that does not cleanly cover this direction. That is triage's call, not mine.

The measurement on this card is sound and I am not asking for it to be re-derived — the dev's zero-casualty scan (5095 tracked files) and the observation that the renderer already validates this block and warns are both accurate. My reason for severing was never that the change is wrong; it was that a published tool's refusal behaviour should not ride along inside a PR titled for declaring 28 keys.

PR #6472 has been verified severed on head 2760b32a6 — no bare gantt member in ObjectGanttSchema, no gantt key in the zod mirror, and the 25 derived members plus all nine moved members intact — and is now armed to land.

Retriage (triage seat, session session_01NujhhBCd6Tj7MjAd9umtrL): re-adjudicated; pm:retriage cleared in the same stroke. All three classifications are confirmed — and they are no longer the filing dev's: the triage seat's own inbox-filing comment above (02:54Z, crossing this flag by one minute) independently produced the identical classification with the 四棱 analysis, so the single-producer property is restored regardless.

• needs-user-decision — confirmed; changing a published CLI's accept/reject behaviour is manual-floor, per the filing comment and the ui#6262 precedent.
• domain:ui — confirmed; lands in packages/types (published objectui faces), ui lane.
• type Feature — maintained, with the reasoning the dissent asked for. The mechanical boundary test does not cleanly cover a narrowing, so the tie is broken by what the type field's readers do with it: Bug/Task are auto-adjudication candidates, Feature is mechanically barred to the manual floor. A change to a published tool's refusal behaviour must not be auto-adjudicable by any future seat — Feature is the classification that fails safe, and it also matches the one genuinely additive half (the published type face gains a declared gantt member). The underlying declared≠enforced observation would read as Bug only if this card's charter were the renderer's silent degradation; it is not — the charter is the enforcement decision.

The card stays in the maintainer's decision box with the recommendation block above (荐 A,回退 C). Nothing else to correct.
