imccyu ec601ca13d build(vendor): rescope the vendored Cordis packages into @deepseek-ai
Machine-produced by `pnpm run rescope-vendor --apply` plus the regeneration it
prints: `pnpm install` for the lockfile, `pnpm run gen-third-party-notices`,
`verify-translation-pairing --write` for the touched bilingual pairs,
`gen-doc-graphs`, and one typert snapshot whose ids embed character offsets.
`pnpm run rescope-vendor --check` verifies the result.

Renames nine vendored packages (cordis, cosmokit, schemastery and the six
@cordisjs plugins) and every reference that resolves them: manifest names and
dependency keys, module specifiers including declare-module merges, cordis.yml
plugin names, tsconfig paths, every Markdown fence, and `docs/` prose.
Directory names, upstream versions, and dependency ranges are unchanged, so
vendor/README.md still reads as an upstream snapshot; its manifest table gains
an upstream-name column so THIRD_PARTY_NOTICES keeps MIT attribution pointed
at each fork's origin.

The tutorial tier follows the rename end to end: its yaml fences named plugins
the Loader can no longer resolve, its `ts ignore-check` fences disagreed with
the compiled fences beside them, and its prose quoted both. The contracts that
told readers to keep upstream names — the root convention and the vendoring
cookbook's tree comment and manifest invariant — now say to rescope instead.

Two rules read `@deepseek-ai/` as "another workspace plugin": the client bundle
purity gate now names the vendored libraries a browser bundle inlines, and the
files where a bare `cordis` is an agent-preset id keep that product data.

dsh-brand

English | 中文

The Branded<B> nominal-typing primitive — a tiny, type-only package (no runtime code, no harness-package dependency) shared by every package that owns a cross-boundary id.

What Branded is

A brand makes structurally-identical strings non-interchangeable at the type level: a SessionId cannot be passed where a CallId is expected, even though both are plain strings at runtime.

import type { Branded } from '@deepseek-ai/dsh-brand'

export type SessionId = Branded<'SessionId'>

/** Brand a string as a SessionId (a plain cast — zero runtime cost). */
export function SessionId(id: string): SessionId {
  return id as SessionId
}

Construction goes through the per-id factory in the owning package. Comparison, logging, JSON serialization, and the wire format behave as for an ordinary string; the brand is erased at compile time.

Policy: brand ids that cross package boundaries

A package brands the ids it owns — CallId in dsh-llm, the shared agent/session SessionId in dsh-session, and TaskId in dsh-tasks. Brand cross-package ids that could plausibly be confused; not every string needs one.

This package owns only the primitive. Keeping it dependency-free lets dsh-tasks, for example, brand TaskId without importing an unrelated capability package merely to reach Branded.
