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-file 这类提供方存储原始文档并推送外部编辑；消费方插件注册 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。

来源：packages/settings/settings/src/index.ts

标识

namespace 命名用户文档中一个归插件所有的分节。brand 防止调用方将设置 namespace 与在包或进程之间传递的其他 id 混用；构造时校验小写 kebab-case 语法。

/** 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（资源释放）该 fiber 即移除 namespace 及其观察者。options 携带组合层、owner 的生效时机，以及一个可选的、用于校验 schema 表达不了的约束的钩子。namespace 是一种设置的 kind；每次注册是它在调用方最近的具名 dsh-scope 作用域（agent preset 的 preset/<id>，或全局作用域）下的一个 instance，同一 kind 的每个注册者共享其 schema。instance 按顺序解析 schema 默认值、自己的 base、文档的全局分节与其作用域自己的分节。

/** 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
  /**
   * Reject a resolved section the owner could not act on, for constraints its
   * schema cannot express — a cross-field requirement, or one field's validity
   * depending on another's. Throwing here refuses the *write* that produced the
   * value, so a caller learns at `update`/`replace`/`mutate` instead of storing
   * something that would silently disable the owner.
   *
   * Kept separate from the schema because the schema is also what a
   * configuration surface renders and what an absent section resolves through;
   * folding a cross-field check into it would change both.
   *
   * Once the owner is registered, a stored section that fails this keeps the
   * namespace's last good value and warns, exactly as a schema failure does,
   * so an externally edited document cannot strand a running owner. At
   * registration there is no last good value yet, so a stored section that
   * already fails rejects the registration itself — again exactly as a schema
   * failure does.
   *
   * The check belongs to the namespace kind: the first registrant's check
   * judges every instance, because every instance is the same plugin.
   * @param value - the resolved section, schema-valid by construction.
   */
  validate?: (value: T) => void
}

validate 在 schema 接纳该值之后运行，因此它看到的默认值和组合 base 与 owner 实际看到的完全一致。dsh-llm-pi-ai 用它在写入处拒绝自己无法服务的提供方 profile，而不是先存下来、再让该 namespace 下每条路由失效。

applies 是 UI 提示而非机制：restart 的 owner 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 layers. */
  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 registration's user section — the scope's
   * own section for a scoped registration — and persist it.
   * @param patch - plain-object patch over the user section; JSON-compatible data
   * only (non-JSON values reject with their path before anything persists).
   */
  update(patch: object): Promise<void>
  /**
   * Replace this registration's user section wholesale; absent keys re-inherit
   * the layers below (`replace({})` resets the section).
   * @param section - the complete next user section; JSON-compatible 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() 封装结构驱动 schema 渲染的表单，解析值填充表单，分离出的 base/user 层让表单按字段是否出现在 user 层标注「用户已覆盖」。describe({ redactSecrets: true })——每个对外传输接口都必须传入——从三层剥离 role('secret') 字段并枚举其 {path, set} slot，页面因此能渲染只写输入框而永远收不到机密值。

Cordis API

Generated from source by scripts/gen-cordis-catalog.ts (verified fresh by pnpm run verify-cordis-catalog in doc-sync; regenerate with pnpm run gen-cordis-catalog) — the language sides differ only in locale-specific paired document paths. Signature blocks use a ts cordis-catalog fence and keep the original source JSDoc; dispatch modes are defined in the primer, and the framework-inherited ctx API lives in cordis-api/inherited.md.

ctx.settings — SettingsProvider (abstract seam)

Abstract settings service. Providers implement raw-document storage (load/persist) and push external changes through Settings.publish; the base class owns namespace registration, resolution, validation, change detection, and the settings/updated commit event.

Host service backing the generated ctx.remote.settings namespace. Every remote read uses redactSecrets: true, so a role('secret') field cannot ride a response.
