Confirmed and fixed, each with a regression test that failed first: - Concurrent writes to different namespaces lost whole sections on disk (each persist rendered the full document from a stale text): the local provider serializes render->write->rename->text-commit on one internal persist chain shared by every namespace queue. - One throwing settings/updated listener starved the rest (cordis emit stops at the first throw): commit fans out per listener via events.dispatch, contains individual failures, and rethrows the first INVARIANT-coded error only after every listener ran. - Write queues ignored fiber/service lifecycle: the base init now registers a teardown that refuses new writes and drains queued chains; queued tasks re-verify service liveness and namespace ownership before running and again before committing, so a registrant disposed mid-flight is never notified and a disposed service never commits. - Async watcher invocations could interleave (a slow stale call applied last): each watcher carries a serialized invocation chain — one call at a time, in commit order; JSDoc/doc pages state the async timing. - update/replace borrowed the caller's object until the queued task ran: inputs are structured-clone snapshotted at call time; non-cloneable plain objects reject with a typed error. - Composition guard now proves the documented fallback: the consumer uses the optional scoped-inject shape and boots both with the settings entry (hot publish) and without it (entry-config resolution, no scope). - core-data-structures index: settings.md row added to the sub-page table in core.md/core.zh.md. Both packages hold per-file 100% coverage across repeated runs.

用户设置
English | 中文
dsh-settings 的用户设置 seam 持有一份按 namespace 分节的用户文档，并把每个已注册 namespace 解析为：schema 默认值，然后注册方的组合 base，最后用户分节。dsh-settings-local 这类 provider 存储原始文档并推送外部编辑；消费插件注册 schema 后读取或观察解析值。组合配置仍留在 cordis.yml——namespace 只承载用户可编辑子集。
Source: packages/settings/settings/src/index.ts
标识
namespace 命名用户文档中一个插件所有的分节。brand 使其不与其他跨边界 id 混用；构造时校验小写 kebab-case 形态。
/** Nominal id of one registered settings namespace. */
type SettingsNamespace = Branded<'SettingsNamespace'>
注册
注册把 schemastery schema 绑定到调用方插件 fiber 上的 namespace——dispose 该 fiber 即移除 namespace 及其观察者。options 携带组合层与 owner 的生效时机。
/** Registration options beyond the namespace schema. */
interface SettingsRegisterOptions<T> {
/** Composition-layer values resolved below the user layer (entry-config subset). */
base?: Partial<T>
/** Owner's effect timing, surfaced to configuration UIs; defaults to `live`. */
applies?: SettingsApplies
}
applies 是 UI 提示而非机制：restart 的 owner 只是从不 watch，其值在构造期读取一次，配置界面可为待生效变更加标。
/** When a namespace's changes take effect for its owner. */
type SettingsApplies = 'live' | 'restart'
Owner scope
scope 是面向 owner 的句柄。update 把稀疏 patch 只合并进用户分节（绝不进 base）；replace 整体替换分节，是删除/重置路径——替换中缺席的键重新继承 base 与 schema 默认值。同一 namespace 的写入按调用顺序串行，解析值是深冻结快照。
/** Owner-facing handle for one registered namespace. */
interface SettingsScope<T> {
/** Current resolved value: schema defaults, then `base`, then the user layer. */
get(): T
/**
* Observe committed changes to this namespace's resolved value. Invocations
* of one callback run asynchronously, one at a time, in commit order; a
* rejection is contained and logged like a sync throw.
* @param callback - invoked after each commit with the next and previous values.
* @returns the disposer removing this observer.
*/
watch(callback: (next: T, prev: T) => void | Promise<void>): () => void
/**
* Merge a partial patch into this namespace's user layer and persist it.
* @param patch - plain-object patch over the user section.
*/
update(patch: object): Promise<void>
/**
* Replace this namespace's user section wholesale; absent keys re-inherit
* the composition `base` and schema defaults (`replace({})` resets all).
* @param section - the complete next user section.
*/
replace(section: object): Promise<void>
}
描述符
describe() 为配置界面序列化每个已注册 namespace：schemastery 的 toJSON() 信封驱动 schema 渲染的表单，解析值填充表单。
/** One registered namespace as surfaced to configuration UIs. */
interface SettingsDescriptor {
/** The registered namespace. */
ns: SettingsNamespace
/** Serialized schemastery schema (`schema.toJSON()`). */
schema: unknown
/** Current resolved value. */
value: unknown
/** Owner's declared effect timing. */
applies: SettingsApplies
}
变更提交
每次提交的变更——进程内写入或 provider 观察到的外部编辑——在新值成为权威值之后发出 settings/updated (ns, next, prev, source)，解析值深相等时绝不发出。source 标记区分两条入口路径。
/** Origin of one committed settings change. */
type SettingsUpdateSource = 'update' | 'provider'
