# Vendored Packages
This directory contains source-vendored copies of the Cordis framework and its foundation libraries. They are copied into this monorepo instead of being depended on via npm, so that the harness fully owns its framework layer (auditable, patchable, pinned).
All vendored packages use the **`@deepseek-ai` scope** (`cordis` → `@deepseek-ai/cordis`, `@cordisjs/plugin-<x>` → `@deepseek-ai/cordis-plugin-<x>`). The manifest table records upstream versions and source commits; each package manifest carries its Harness release version and publication metadata. References to vendored packages use `workspace:~`, so local builds resolve the workspace packages and published ranges permit patch updates within the same minor version. Upstream MIT `LICENSE` files are preserved in each package directory.
This file covers the manifest, the local-modification log, and the procedure for **updating** an existing vendored package. To **add a new** one, see the cookbook guide: [docs/cookbook/adding-a-vendored-package.md](../docs/cookbook/adding-a-vendored-package.md).
The proposed [Cordis rc.11 upgrade plan](cordis-rc11-upgrade-plan.md) records the package scope, PR dependencies and intended disposition of the local modifications.

**Partial Loader sync:** the package baseline remains 1.0.0-rc.5. `loader/src/resolve.ts` and the bare-specifier fallback in `loader/src/config/tree.ts` use the resolver implementation from Cordis `v4.0.0-rc.11` (Loader 1.0.0-rc.8), and `loader/src/internal.ts` uses its runtime API detection, which classifies the internal module loader by its available module-job APIs instead of the Node major version; the Node compatibility matrix covers the detection. The [resolver adaptations](#resolver-adaptations) below record the local differences from that newer source.
Third-party dependencies of the vendored packages stay on npm: `@standard-schema/spec`, `js-yaml`, `chokidar`, `picomatch`, `@babel/code-frame`, `supports-color`, `node-addon-require-builtin`.
Intentionally **not** vendored (verified unused by this set): `reggol`, `@cordisjs/utils`, `@cordisjs/element`, `@cordisjs/unyaml` (dev-time YAML import hook only).
## Local modifications
Keep this log exhaustive — every divergence from upstream must be listed. Each entry has a stable ID: remove an entry when its divergence no longer exists, and never renumber or reuse IDs. The next new entry is V26.
- **V1 · `hmr/src/index.ts`**: removed the `./locales/en-US.yml` / `./locales/zh-CN.yml` imports, the `.i18n({...})` call on the `Config` schema, and the `src/locales/` directory. Rationale: those imports require a runtime YAML loader hook (`@cordisjs/unyaml`) that we do not vendor; the i18n texts only localize config descriptions.
- **V2 · All `package.json` files**: regenerated for Harness releases with scoped names, release versions, publication metadata, precise bundled-runtime and `lib/types/**/*.d.ts` / `.d.ts.map` file entries, source exports where applicable, and declaration metadata pointing at `lib/types`. References within the vendored set use `workspace:~`. HMR declares `esbuild` as a direct dev dependency for its imported `BuildFailure` type, and Loader requires `node-addon-require-builtin@^0.1.4` to match published app runtimes.
- **V3 · All `tsconfig.json` files**: regenerated to extend the repo-root `tsconfig.base.json`, emit TypeScript intermediates to `lib/types`, and declare project references.
- **V4 · Vendored TypeScript source internal specifiers**: changed local relative imports/exports from upstream's specifier shape to explicit `.ts` specifiers so TypeScript rewrites emitted JS to `.js` while declarations keep explicit, NodeNext-safe `.ts` specifiers. This includes `loader/src/config/isolate.ts` using `declare module './entry.ts'`. Type-only dependencies use `import type` or inline `type` modifiers so ESM output does not retain erased interfaces.
- **V5 · `schemastery/tsdown.config.ts` and `logger-console/tsdown.config.ts`**: ours, not upstream files — per-package build-shape overrides (dual ESM+CJS output; separate node/browser entries) for the repo-root tsdown build. They read the JS emitted under `lib/types` and then write the publish runtime entries under `lib/`. Like the regenerated tsconfigs, they are not part of the upstream sync surface.
- **V6 · `cordis/src/fiber.ts` lifecycle hardening**: locally closes three reentrant disposal gaps. An effect's owner-list wrapper is registered before its setup body runs, so an unload begun from inside setup awaits setup and every collected cleanup; synchronous setup failure removes the wrapper and rolls back collected cleanup. Async cleanup stays owner-visible until quiescence, and Cordis's internal effect composition joins an already-running cleanup while repeated public disposer calls retain their upstream single-shot result. Effect creation is rejected while the owner is `UNLOADING` (while `PENDING` and `LOADING` remain legal), preventing cleanup-time registrations from escaping the unload snapshot. Child fibers register and receive their parent-owned disposer before `internal/plugin` publication, resolve dependency declarations added by that notification before activation, drain effects attached while pending, and contain teardown-notification failures per observer so one callback cannot starve peers or interrupt ownership cleanup.
- **V7 · Cordis, Loader and Timer JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), module re-exports, shared utility helpers, `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Loader documentation covers `loader/src/{index,internal,config/entry,config/group,config/isolate,config/tree,config/utils}.ts`, including entry ownership, tree mutation methods, and the `!!js` discriminator. Timer retains its local class and helper summaries; its README is local documentation because the upstream package has none. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members. Retire this entry when the enrichment is upstreamed to the fork.
- **V8 · `include/src/index.ts` resilient file refresh and patch reapplication**: [#514](https://github.com/deepseek-harness/deepseek-harness/pull/514) validates a top-level entry array before caching parsed content, logs refresh failures, reapplies patches after file or Include-config edits, updates the Include config when it vetoes a restart, and uses `initial` only after `ENOENT`. These parse protections retain the running tree after an invalid file; plugin activation failures can leave a partially applied tree. Loader entry/group/tree mutations follow the pinned eager, non-transactional implementation and do not restore previous plugins or options. Covered by `packages/boot/app-boot/tests/{config-reload,user-patches}.spec.ts`.
- **V9 · `hmr/src/index.ts` module-watcher readiness and native paths**: realpath the existing watch base, classify framework modules and attach listeners before reporting readiness, and compare config paths using both canonical and configured spellings. This preserves Node module-cache identity across Windows short-name paths and filesystem aliases. The main watcher uses `ignoreInitial: true` so startup reads do not trigger another refresh; exact profile patch watching is owned by `packages/boot/hmr/src/watch-config.ts`. Covered by `packages/boot/hmr/tests/watch-config.spec.ts`.
- **V10 · Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`. Conditional exports select `.mjs` for import and `.cjs` for require; without them, concurrent imports under module-hook hosts reach the CJS entry and can race its require of ESM Cosmokit (`ERR_REQUIRE_ESM_RACE_CONDITION`).
- **V11 · `include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree. The entry list is deep-cloned when patches are present; without patches, the returned array retains the entry objects. Public patch and Include fields carry JSDoc for config tooling. Behavior-preserving for mounting; the extraction exists because config tooling must never reimplement (and drift from) the patch algorithm. `applyEntryPatches` also indexes each `insert`ed entry as it is added, so a later patch in the same list can configure or disable a row an earlier patch inserted; upstream built the id index once before the patch loop, leaving inserted rows silently unpatchable. That matters because `dsh` composes an empty profile root with each bundle's patch layer, the profile's and the home-level `cordis.patch.yml`, and any `--patch` overlays as sibling patch lists at one include level — patches never cross an include boundary, so surface-only rows would otherwise be unreachable from user config. Covered by `packages/boot/app-boot/tests/config-reload.spec.ts`.
- **V13 · `include/src/index.ts` `writeTask` type**: widened the optional `writeTask?: NodeJS.Timeout` property to `NodeJS.Timeout | undefined` — the debounced writer assigns `undefined` on flush, which `exactOptionalPropertyTypes` rejects on a plain optional. Type-only; no behavior change.
- **V14 · `include/src/index.ts` durable debounced writes**: serialized and tracked config-file writes, retried transient `EACCES`/`EBUSY`/`EPERM` rename failures with a bounded backoff, observed asynchronous timer rejections, and drained writes before and after child removal during Include teardown. The first drain preserves an existing terminal write failure even if child removal schedules a later write. Missing-file initialization awaits the write and forces a fresh parse before mounting the initial entries. Windows can briefly retain a destination handle after a Loader child disposes; the upstream fire-and-forget rename escaped as an unhandled rejection and could lose the persisted `disabled` state. A terminal failure is logged by the asynchronous writer and remains on the queue so `Include.stop()` rethrows it instead of silently declaring persistence complete; Cordis's ordinary fiber teardown retains its separate error-containment contract. Covered by `packages/host/directory-picker-auto/tests/loader-composition.spec.ts` with injected transient and terminal rename failures.
- **V15 · Configuration access across Core, Loader, Include and HMR**: rc.11 Core owns raw `Fiber.config`, `internal/config(fiber, next)`, `internal/commit` and awaited `internal/update(config, next)`. Root-fiber candidate resolution remains available without a plugin schema. Local `rawConfig`, `resolveConfig(candidate)` and `effectiveConfig` accessors retain the DSH consumer API. Fiber caches the object passed to activation or a successful update that keeps the instance; candidate resolution is pure, failed or superseded updates cannot replace the cache, and volatile updates retain references. Loader resolves only entry roots and excludes Group/Include tree carriers, so nested `!!js` expressions wait for their own injections. Include retains its tree-carrier marker, writer and patches, and HMR transfers raw config through the accessors. Covered by `scripts/cordis-config-access.spec.ts`, `scripts/cordis-core-lifecycle.spec.ts` and the boot/HMR suites.
- **V16 · `cordis/package.json` publishes `src`**: added `src` to the `files` list, joining the other eight vendored packages. Cordis declares `"./src/*": "./src/*"` in its exports, so a tarball without `src` publishes an export map pointing at absent files; the release change judgement also reads `files` to decide whether a diff reaches the payload, and a package whose only published paths are build output has no tracked path to match.
- **V17 · `@deepseek-ai` rescope**: every vendored manifest `name`, every internal dependency entry among the vendored set, and every module specifier that reaches them use the scoped names in the manifest table's `npm name` column. Directory names, version numbers, and dependency ranges are unchanged, and no upstream runtime identifier is renamed — `Symbol.for('schemastery')` and Schemastery's `vendor:` metadata field keep their upstream values. Re-apply with `pnpm run rescope-vendor --apply` after a sync; the table's two name columns are the mapping, restated for consumers in [docs/rescope.md](../docs/rescope.md).
- **V18 · Entry `disabled` interpolation in `loader/src/config/entry.ts`**: a `disabled: !!js` expression evaluates against the loader context at every mount decision; the raw node stays in the options, so write-back keeps the `!!js` form. `disabled` is the only interpolated metadata field. Covered by `packages/boot/app-boot/tests/user-patches.spec.ts` and `apps/cli/tests/windows-shell.spec.ts`.
- **V22 · Volatile config across `cosmokit`, `schemastery`, `cordis`, and `loader`**: Cosmokit supplies immutable references and framework-owned commits; `deepEqual` treats two references as equal, propagates strict comparison into arrays, compares every array slot with holes treated as undefined, handles cycles conservatively, compares URLs by normalized href, and compares other opaque objects by identity in strict mode. Schemastery adds `.volatile()`, optional/default inference, placement validation without eager lazy-schema expansion (a lazy inner is validated once when built), metadata-free serialized node compatibility, serialized metadata, reference-aware simplification, unsupported volatile values reported as `ValidationError` with their path, and `.default()` accepting the raw input type `Partial<S>` because a volatile field makes the output type carry references. Loader's save path calls `simplify` with its schema receiver (`unparse.call`), an independent fix for the unbound-`this` call. Cordis exports consumer types without changing Fiber lifecycle. Loader compares raw options strictly in `Entry.update`; for a config-only change on an active fiber it calls the pure `equalExceptVolatile` function in `config/diff.ts`, which narrows the Standard Schema to Schemastery's `Schema` type (a new type-only `@deepseek-ai/schemastery` dependency of `loader`) and recursively skips fixed volatile paths using schema metadata without executing config hooks or validation. Missing or null object nodes compare using their declared defaults, including nodes without volatile descendants; schema backedges retain raw comparison. Entry passes its actual schema and preserves ordinary context and custom-update lifecycles. For a volatile-only change, `Entry._commitVolatile` takes the canonical fiber `entry.fiber.ctx.fiber` (`Entry.fiber` holds the registry wrapper), re-parses the raw config through `Fiber.resolveConfig()`, compares ordinary effective values, commits references and emits the instance-local `loader/volatile-update` declared in `loader/src/index.ts`; a changed ordinary effective value falls back to the ordinary remount, and an invalid candidate is logged while the raw config stays retained for the next activation. Cosmokit provides reference enumeration and commits, and `simplify` is called with its schema receiver. The package READMEs document these additions; schema tests live in `scripts/volatile-config.spec.ts`, Loader runtime and real-file tests in `scripts/loader-volatile-update.spec.ts`, and code replacement tests in the HMR module suite.
- **V23 · `loader/src/config/entry.ts` module identity**: retains each entry's raw import result as `moduleNamespace`, before plugin export normalization. HMR matches that object to Node's cached module namespace and updates it after a successful reload. `EntryTree.import()` keeps its existing arguments and return value; `loader/README.md` documents the additive field.
- **V24 · `timer/locale/{en,zh}.json` display metadata**: local English and Chinese titles and descriptions for the Settings plugin inventory. `timer/package.json` exports and publishes these locale resources.
- **V25 · Loader lifecycle slice from Cordis v4.0.0-rc.11**: entry updates await context patches, Fiber updates and disabled-entry disposal; isolation uses `Impl.ctx` and maintains `Impl.isolate` during transfers; the `Entry.init()` observer handles both activation outcomes. Group and Include return their child-update work. The existing writer receives `internal/commit` with schema-bound simplification. A local dependency refresh before a combined context/config update prevents activation against stale isolation bindings. Loader, Include and HMR keep their manifest baselines apart from the slices recorded in this log. Failed fibers require an explicit update after correcting their input or dependencies. Core retains the effect hardening in V6; rc.11 owns dependency teardown ordering and superseded-activation handling.
### Resolver adaptations
Relative to the resolver source in Cordis `v4.0.0-rc.11`:
- **Web build imports:** `loader/src/resolve.ts` uses default imports for Node builtin modules to support the Web shell's browser externalization. The shell supplies its own module loader.
- **Package-scope cache keys:** `loader/src/resolve.ts` normalizes directory paths with `path.resolve()` before finding the package scope. A root config and a nested config in the same package therefore share the same cached resolver promise and helper-file write. Covered by `scripts/cordis-loader-resolve.spec.ts`.
## Sync procedure
To update a vendored package from upstream:
1. In the upstream workspace, note `git rev-parse HEAD` of the relevant submodule.
2. Copy the package's `src/` (and `bin.js`, `README.md`, `LICENSE` if changed) over the vendored directory.
3. Re-apply the local modifications listed above (or drop them if upstream made them unnecessary — update the log either way).
4. Update the version and commit hash in the manifest table.
5. Run `pnpm install && pnpm run test && pnpm run build` at the repo root.
