Customization pairs: every system package shares namespace sys, so only the first can get a .custom pair (422 NAMESPACE_CONFLICT on the rest) #29594
Description
domain:ui#1 · zhuangjianguo · session_01QsR2jUJ19MstFvFhjgiYTu
Filing gate: ② out-of-scope finding, class b, from #29567 (PR #29591; os-dev report card comment 6587695831, /mnt/project-files/issue-29567/os-dev-report.json) · filed by domain:ui#1 · ⛔ Not a claim. No grade: triage sets it.
Business reason. After #29567, Studio shows a system-scope package as read-only and offers Customize, because the ensure door accepts the first one. For every other system package that Customize fails on the first save: their pairs all want the same namespace. Whether more than one system package should be customizable is a product decision, and today the code answers it by accident, first come first served.
Measured (the #29567 dev, fresh dev:crm at PR #29591 head f933fef7).
POST /api/v1/packages/com.objectstack.plugin-auth/ensure-customization→ 201. The pair iscom.objectstack.plugin-auth.custom, namespacesys_custom, range^3.- The same door for
com.objectstack.plugin-securityand forcom.objectstack.audit→ 422NAMESPACE_CONFLICT: "namespace 'sys_custom' is already owned by package 'com.objectstack.plugin-auth.custom'". - 18 of the 25 listed packages are scope
systemwith namespacesys, so only one of them can ever hold a pair. - The console cannot tell beforehand: the package list does not say who owns a namespace, so Customize is offered and then refused at the first save.
Where. packages/metadata-protocol/src/protocol-customization-package.ts derives the pair namespace from the base namespace (<ns>_custom) and refuses 422 when another package owns it.
Wanted. A decision, then the matching change:
- (a) System packages are customizable, each with its own pair. The pair namespace must then be unique per base, for example derived from the package id when the base namespace is shared. The 422 stays for real conflicts.
- (b) Only some system packages are customizable, or none. The server then says so on the listed row or the ensure door's verdict, so the console stops offering Customize where it will fail.
- Either way, the console needs a readable answer before it offers Customize. fix(studio): open system-scope packages read-only, with Customize #29591 offers it on every read-only system package.
Reader. Server metadata protocol (domain:server). The choice between (a) and (b) is a product call: route it to the director if triage can't settle it. The console adopts whichever verdict the server serves as a follow-up in domain:ui.
Noted, not measured: a system base's .custom pair lists as its own switcher row in Studio, because the fold needs the base in the list, and kernel packages are kept out of it. Read in code by the #29567 dev.

sys, so only the first can get a.custompair; the rest answer 422NAMESPACE_CONFLICT. Since Studio: a system-scope package opens as editable, with no read-only chip and no Customize, because parsePackages drops system and cloud packages #29567, Studio offers Customize on all of them, so the action fails on first save for every system package but one. p2.Generated by Claude Code

一句话问题: 管理员在 Studio 里对平台自带的任何一个系统包点「自定义」,只有第一个被点的包能成功,其余 17 个都在第一次保存时被拒,而界面事先看不出哪个会失败。
背景: #29567 的 PR #29591(草稿,head
f933fef7,未合并)让 Studio 把 scope 为system/cloud的包读成只读并提供「自定义」。该卡 dev 实测发现:POST /api/v1/packages/com.objectstack.plugin-auth/ensure-customization回 201(配对包com.objectstack.plugin-auth.custom,namespacesys_custom,range^3);随后对com.objectstack.plugin-security与com.objectstack.audit同一门回422 NAMESPACE_CONFLICT("namespace 'sys_custom' is already owned by package 'com.objectstack.plugin-auth.custom'")。列出的 25 个包里 18 个是 scopesystem、namespacesys。分诊 6588307532 定 p2 入pm:queue。本席立卡呈裁,⛔ 不是认领。Governing text(引文 + grep):

Metadata-protocol: yes,且packages/metadata-protocol/src/protocol.ts(读于2da42e74的 L23826,E2 拆分后可能已移位)的ensureCustomizationPackage文档块("<base namespace>_custom, set explicitly and never derived")随之要改——该文件席 5 的冻结已于 2026-11-02T21:10Z 解除(#29590 合并);(b)在包行新增一个服务端判定键(SERVED_ROW_VERDICTS,packages/spec/src/api/package-api-assembled.zod.ts:175),Clause-②: yes (widening);(c)不改任何公开键名与推导规则,只改 ensure 门与注册表的「谁算共有者」判定,Metadata-protocol: none,protocol.ts的那段文档块仍为真("a pair namespace another package owns (422 NAMESPACE_CONFLICT)"),可不动。前提(带复查命令):
sys—git grep -n -E "namespace: ?'sys'" origin/main -- packages | grep -v test | wc -l(本席读数 27 行,含object.zod.ts一处文档串与.md引用;scopesystem且装进dev:crm的即 dev 实测列出的 18 个);<base_ns>_custom一种拼法 —git grep -n "CUSTOMIZATION_NAMESPACE_SUFFIX" origin/main -- packages/spec/src/kernel/customization-package.ts;git grep -n "whatever co-ownership" origin/main -- packages/metadata-protocol/src/protocol-customization-package.ts为 1 行;git grep -n "coOwnersOf" origin/main -- packages/objectql/src/registry.ts;gh api -X GET repos/objectstack-ai/objectstack/pulls/29591 --jq '.merged,.state'。名字空间在下游的用法(读码,非猜测): 名字空间是对象名的强制前缀(
manifest.zod.ts:564:"also the mandatory prefix of every object name"),也是物理表名前缀;D3 下客户在配对包里新建对象名为<ns>_custom_<short>。扩展字段走__c后缀(D10),不带名字空间。两点与本卡直接相关:validateObjectNamespacePrefix(packages/spec/src/kernel/namespace-prefix.ts:33)对任何sys_开头的对象名直接放行。于是今天唯一能建出的sys_custom配对包,其对象无论叫sys_custom_x还是sys_whatever都过前缀门;ADR-0029 D4 的「app 不得定义sys_*」在代码里仍无执行点(RESERVED_NAMESPACES仍是{'base','system'})。这是现状缺口,不随本卡字母变化而消失,只有 (a) 把名字空间推离sys_前缀才顺带避开。NAMESPACE_CONFLICT在两处:注册表installPackage(ADR-0048 Phase 1 门,registry.ts:7729,对sys豁免、对声明依赖的共有者豁免)和 ensure 门(protocol-customization-package.ts:352,比注册表更严:不认任何共有者)。所以修 (c) 要改两处,只改一处不够:ensure 门放行后installPackage仍会因sys_custom非共享而抛NamespaceConflictError(配对包声明的依赖是持sys的 base,不是持sys_custom的包,D5 的 parent/sibling 两臂都不命中)。系统包装了什么、定制对客户有没有意义: 读码:
com.objectstack.plugin-auth带pages、dashboards(system_overview,#29567 的实测路径)、导航贡献;com.objectstack.audit带 4 个对象及其 listViews、翻译;plugin-email带邮件模板;三个 cloud-connection UI、mcp.connect-agent-ui、connector-credentials-ui、settings.setup-nav只带pages+ 导航。按OVERRIDE_TYPE_CLASSIFICATION(customization-package.ts),可整体覆盖的是 view/dashboard/report/translation/email_template/page/app 等;对象只能扩展(__c字段 + 显示属性白名单,D10);权限集/职位/能力excluded(D6)。所以「定制 plugin-security」能做的是:给sys_permission_set等加__c字段、改标签、覆盖它的页面;⛔ 不能改权限集本身,不能改字段类型/必填/引用。安全面:ensure 门要manage_metadata,walled 姿态下租户管理员 403、只有运营方能建(D3「Walled postures」);覆盖平台 Setup 页面会换掉管理员看到的页面但不改数据面权限。读码判断:风险由既有闭合清单与姿态门兜住,与定制 HotCRM 同级;真正的额外风险是上面那条sys_前缀放行,它让配对包能造出看起来像平台对象的sys_x,这需要独立修,不是本卡的字母能决定的。控制台两边都需要什么: PR #29591 从列出行的

sys),它的定制层也是一个东西(sys_custom),每个系统包仍各有自己的定制包与导出——类似 Salesforce 的标准对象:客户定制都落在同一客户层,不按平台内部模块分名字空间。四维(业务立场):
sys定下的「共享名字空间、单一对象所有者」规则,把它对称地用到sys_custom,不新增拼法;(a) 新增一条推导规则或一个 manifest 键,还把内核拆包暴露进客户对象名,而且按 id 推导已实测撞 20 字符上限;(b) 把一次偶然的「先到先得」或一次关门写进契约。sys_custom即对,同名对象被OBJECT_OWNERSHIP_CONFLICT响亮拒绝;(a) 下 AI 要在新键与推导之间猜拼法;(b-部分) 下失败与否取决于点击顺序,AI 无法从声明推出结果。各选项共同的静默面是namespace-prefix.ts:33对sys_的放行——配对包能造出像平台对象的sys_x而不被拒,须另立卡堵上。os-decision-facets
① 项目长远合理性: (c) 把 ADR-0029 D3 为
sys定的「共享名字空间、单一对象所有者」对称用到sys_custom,不加拼法;(a) 加推导/键并暴露内核拆包;(b) 把先到先得或关门写进契约。② 实际业务拉动: #29591 之后 18 个系统包里 17 个的「自定义」必在首次保存失败;D11 迁移对系统包条目只能迁一个包的覆盖行。
③ 防 AI 犯错: (c) 照 D3 Q4 写即对,同名对象响亮 422;(b-部分) 结果取决于点击顺序;各选项共有的静默面是
sys_前缀放行,另立卡。④ 创业阶段不扩散: (c) 零新键零新语法;(b) 加一个永久行判定键;(a) 加 manifest 键或改语法并迁移已建配对包。
