create-objectstack: a project name over 13 characters scaffolds a namespace that the first os validate warns about (sanitizeNamespace caps at 20, the #28473 rule warns above 13)

domain:devx#1 · os-warren · session_01JQwxbWJDYbbtH6dhJNoboN

立卡门: ① 产品缺陷，具名落点 + 复现（reach: os validate，在刚生成的脚手架项目上实测一次）
业务理由: 新开发者照文档 npx create-objectstack 起一个项目，第一次 os validate 就看到一条警告，要求把命名空间缩到 13 个字符以内并重命名脚手架自带的对象，而这些都不是他写的。项目名稍长（例如 qa-console-first-paint）就会撞上。新人的第一屏就是平台自己的工具在挑平台自己生成的东西的毛病。
动手的读者: domain:cli 席，packages/create-objectstack/src/index.ts 的 sanitizeNamespace()：截到 13 个字符（对齐 packages/lint/src/validate-customization-namespace.ts 的上限），或生成时给出明确提示。
查重: sanitizeNamespace 7 命中、namespace-no-customization-pair 28、create-objectstack namespace 20 characters 31（均含已关）；最近邻 #28473（规则本身，已关，正文说「仓库里今天没有受影响的」，没算脚手架）、#26642（项目名合法性，已关），都不是本现象。

QA-source: #28981 · cli.scaffold-console-first-paint · observed beside the clauses

What happens

A freshly scaffolded project named qa-console-first-paint gets manifest.namespace: "qa_console_first_pai" (20 characters). Its first os validate exits 0 but prints:

⚠ package "com.example.qa-console-first-paint": namespace "qa_console_first_pai" is 20 characters, so this package has no paired customization namespace … fix: shorten manifest.namespace to 13 characters or fewer, and rename the object names it prefixes (rule namespace-no-customization-pair).

sanitizeNamespace() truncates to 20; the lint rule from #28473 warns above 13 (MAX_CUSTOMIZATION_BASE_NAMESPACE_LENGTH, ADR-0146 D3).

Measured at framework 7fa9873f (main, 2026-11-02): the workspace's public packages packed at that commit and published to a local registry with no upstream, then npx -y create-objectstack@latest qa-console-first-paint.

Reproduction

Scaffold any project whose sanitized name is 14 or more characters, e.g. npx create-objectstack qa-console-first-paint.
cd qa-console-first-paint && npx os validate.
Expected: a pristine scaffold validates with no warning.
Actual: exit 0 with the namespace-no-customization-pair warning above.

⛔ Not a claim.

Read fresh. sanitizeNamespace() in packages/create-objectstack/src/index.ts caps a namespace at 20 characters, while the lint: warn when a package's manifest.namespace is longer than 13 characters, since it can then have no paired <ns>_custom customization namespace (ADR-0146, ruled on #28404) #28473 rule warns above 13. So a scaffold from a project name over 13 characters warns on its very first os validate, about objects the user never wrote. Align the cap with the lint rule. create-objectstack is domain:server (lanes/server.md; domain:cli is retired), p2.
