[Decision] 记录页上「全部字段都为空」的分区，是逐行显示「—」，还是像其他分区一样折叠成「N 个空字段 · 展开」——objectui#12618

Ruled: 6369306878 · batch #7 item 4 · letter C · 2026-10-23T16:08:53Z (read-only mode: an all-empty hideEmpty: false section renders its heading plus one 「N 个空字段 · 展开」 row; edit mode unchanged; no new key; spec describe-text card first, objectui#12618 Blocked-by it; HotCRM unchanged)

立卡门类别：② 只有维护者能做的决定（元数据协议的语义变更或新增）。动手的读者：裁定后由 objectstack domain:spec 席和 objectui domain:ui 席执行。立卡：objectstack 分诊席（session_01AavokzJ5DndAwitDXvKy4U），按维护者 2026-10-23 在分诊会话的指示「12614 12618 决策卡」。

维护者速读

商机记录页的「交易说明」「备注与下一步」两个分区，所有字段都还没填，于是逐行显示「客户背景 —、项目背景 —、风险分析 —……」一整列短横线。同一页上「部分有值」的分区，空字段会收成一行「显示 4 个空字段」。走查希望全空的分区也这样折叠。

原因：HotCRM 在这些分区上故意写了 hideEmpty: false。它要分区标题一直在，提醒销售去填。协议目前对全空分区只有两种画法：默认整块不显示；写 false 就逐行显示空行。没有「保留标题 + 折叠」这一种。

A 维持：协议不变，Record page: a section whose fields are all empty folds like the others instead of showing dashes #12618 关闭。HotCRM 想去掉短横线就删掉 false，但那样整个分区会消失。
B 新增第三种状态：例如 hideEmpty: 'fold'，HotCRM 改用它。
C 改 false 的含义（推荐）：只读模式下，false 的全空分区显示标题加一行「N 个空字段 · 展开」，和混合分区一致；编辑模式照旧逐行可编辑。不加新键，HotCRM 不用改。

~~选 A、B 还是 C？~~ 已裁 C（批 #7 第 4 项，评论 6369306878）。

触发的上报标准： 元数据协议变更（B 是新增，C 是语义变更），按你的口径属于「协议变更直接处理、和我沟通」。工作量都在 S–M 之内。

一句话问题

一个全空、但作者要求保留的分区，现在只能画成一列短横线；同一页上其他分区用的是更紧凑的折叠行。

现状

协议原文（@objectstack/spec packages/spec/src/ui/component.zod.ts，record:details 分区的 hideEmpty）：默认开启，全空分区不画标题、不画骨架；设为 false 时画出空行，新记录上也保留分区骨架。
渲染器：objectui DetailSection.tsx 正好实现了这两种状态。混合分区的「显示 N 个空字段」是另一条规则（objectui#7129 Q2-C）。全空分区的默认行为是在 objectui#8603 恢复的（总监批次 [WIP] Fix component registration issue in documentation page #137 第 3 项，维护者 2026-09-15）。
作者用量：HotCRM origin/main 有 14 处 hideEmpty: false：opportunity_detail.page.ts 7 处，lead_detail.page.ts 5 处，case_detail.page.ts 2 处。注释里写明是为了「全空时也要留在页面上」（The opportunity's 详情 tab renders two fields out of the fourteen it authors — highlight fields are dropped and the sections left empty disappear hotcrm#1211）。objectstack 的 examples/ 和 platform-objects 里没有。

选项

选项	做什么	用户能感知的后果	工作量
A 维持	不改	新记录上还是一列「—」	0
B 新增 `'fold'`	spec 给 `hideEmpty` 加第三个值（`Metadata-protocol: added`）；objectui 渲染；HotCRM 把 14 处改成 `'fold'`	用了新值的分区折叠；`false` 照旧	spec 1 PR（S）+ objectui 1 PR（S）+ HotCRM 1 PR（XS），按协议新增定 p1
C 改 `false` 的只读画法	spec 改 `hideEmpty` 的说明文字（`Metadata-protocol: semantic`）；objectui 在只读模式下给 `false` 的全空分区画标题加折叠行；编辑模式不变	所有写了 `false` 的分区都变成折叠，标题还在，点「展开」可见全部字段	spec 1 PR（XS，只改说明和生成物）+ objectui 1 PR（S），HotCRM 不用改

第 2 项诉求（一个标签页里所有分区都为空时只显示一行）随本裁决一起走：选 B 或 C 时，按同一规则在标签页层面再折叠一次。

裁后执行

裁 A：objectui#12618 关闭 not_planned。
裁 C（已裁）：在 objectstack 立 domain:spec 卡（改说明文字，Metadata-protocol: semantic，18.x 直接处理），objectui#12618 带 Blocked-by: 指向它；spec 落地后由 ui 席改渲染器。完成标准：HotCRM 商机新记录的「交易说明」只显示标题和一行「4 个空字段 · 展开」；编辑模式逐行可编辑；混合分区不变；有测试。
裁 B：同上，spec 卡改为新增 'fold' 值（Metadata-protocol: added），另立 HotCRM 卡改用它。

Blocked-by: objectstack-ai/objectstack#25511

Ruling C (batch #7 item 4, above) orders the spec's hideEmpty describe text first, and the renderer after. This card is now the execution card, so it carries the Blocked-by: that the ruling put on objectui#12618. State: pm:queue → pm:blocked. When the spec card closes completed, the unlock scan returns this card to pm:queue.
objectui#12618 stays pm:on-hold and closes with this card.

pm:blocked → pm:queue. The grade is unchanged: p2 · domain:ui · area:records. ⛔ Not a claim, ⛔ not a dispatch.

The blocker landed. spec(ui): record:details hideEmpty: false — in read-only mode an all-empty section renders its heading plus one "N empty fields · Show" fold row; say so in the describe() text (ruling C on objectui#13386, Metadata-protocol: semantic) objectstack#25511 closed completed at 2026-10-24T10:42Z through PR spec(ui): record:details hideEmpty: false — in read-only mode an all-empty section renders its heading plus one fold row; describe() says so objectstack#25612 (merge 2af790ffaa). The PR changes only the hideEmpty describe text, the reference page and a changeset. No key, shape or default changed.
Why it unlocks before the pin carries it: ruling C orders "the renderer once the spec lands", and the spec has landed. The DetailSection.tsx change imports nothing new from @objectstack/spec, so it builds on the current pin. The pin move objectui#13440 targets e649c2d91e, which predates 2af790ffaa, so a later pin move picks up the describe text.
Done when (from the ruling): a new HotCRM opportunity's 「交易说明」 shows its heading and one 「4 个空字段 · 展开」 row in read-only mode, edit mode stays row by row, mixed sections are unchanged, and tests cover it. Item 2 (a tab whose sections are all empty folds once more) rides the same PR.
objectui#12618 stays pm:on-hold and closes with this card.

Ruling (verbatim, 6369306878): batch 构建一个 **Live Playground (实时演练场)** (用于展示引擎能力) #7 item 4, letter C, maintainer 「objectui 三个都同意」: "in read-only mode an all-empty section authored hideEmpty: false renders its heading plus one 「N 个空字段 · 展开」 row, the same fold the mixed sections use (objectui#7129 Q2-C); edit mode is unchanged (every row editable); no new protocol key. Item 2 of Record page: a section whose fields are all empty folds like the others instead of showing dashes #12618 (a tab whose sections are all empty folds once more at the tab level) goes with it."
Done when (ruling): a new HotCRM opportunity's 「交易说明」 shows the heading and one 「4 个空字段 · 展开」 row; edit mode row by row; mixed sections unchanged; tests. The PR carries Fixes #13386 and closes objectui#12618 with it.
Metadata-protocol reason: the renderer carries out the spec's semantic change to hideEmpty: false (spec(ui): record:details hideEmpty: false — in read-only mode an all-empty section renders its heading plus one "N empty fields · Show" fold row; say so in the describe() text (ruling C on objectui#13386, Metadata-protocol: semantic) objectstack#25511); no key is added.
