The seam README states the JSON-shaped write boundary, watch-disposer quiescence, async listener containment, and the drained teardown; the provider README rewrites Behavior around the operation chain, read-modify-write, writer lock, ready reconcile, and leaf-level YAML diffs, and updates Known Limitations to the residual guarantees. A new Agent Note records the round's decisions and supersedes the original note's deferred-lockfile alternative (cross-linked in place). Chinese counterparts updated pair-by-pair (three briefed minimal updates, one whole-document translation); type-equiv, config, cordis, and module-graph catalogs re-recorded.

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. After the disposer
* returns, no further invocation starts — one already queued is skipped;
* one already started still settles, and service disposal waits for it.
* @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; JSON-shaped data
* only (non-JSON values reject with their path before anything persists).
*/
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; JSON-shaped data only,
* as for {@link update}.
*/
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'
