The reconnect supervisor used connection lost for every transition into backoff, including an initial startup attempt that never established a connection and later retry attempts that also failed. That wording implied a previously healthy generation and obscured whether any tools had ever been registered.
Capture whether the generation had reached the established state before scheduling recovery. Established disconnects retain connection lost/reconnecting; startup and retry failures now report connection failed/retrying. The reconnect-disabled diagnostic uses the same distinction while preserving its concrete manual-recovery guidance.
Unit assertions cover established loss, initial failure, retry failure, and both reconnect-disabled branches. Focused package coverage remains 100%, and the bilingual Agent Note records the observable state vocabulary.
Strict startup intentionally wraps connection and synchronization failures with the server-qualified activation diagnostic while retaining the original error in Error.cause. The prior assertion checked only the wrapper text, so the causal chain could regress unnoticed and erase the actionable transport failure.
Assert the full wrapper message and object identity of the original connection error in cause. This keeps operator-facing context and the underlying SDK diagnostic independently stable without changing production behavior.
The failure-cap path already appends tool disposal to syncChain, but the existing tests only covered give-up after settled discovery. They could not detect a future change that disposed the old set immediately and then allowed a blocked re-sync to publish a new leaked generation.
Hold a list_changed fetch open, drive the reconnect budget to exhaustion, then release a different tool list. The test proves final cleanup runs after that in-flight swap and removes both the previous and late-published tool names while creating no attempt beyond the configured cap.
The supervisor selected strict startup registration with a shared isFirstSync flag. Because the MCP SDK may deliver tools/list_changed before connect() resolves, that notification could enter the sync queue first, consume the strict option inside its contained handler, and leave the actual activation sync non-fatal.
Pass startup intent explicitly to connectGeneration(). Only the plugin activation attempt receives the failOnStartupError registration policy; notification-driven syncs and later reconnect generations always use contained runtime semantics. Queue arrival order can no longer redefine startup behavior.
A regression test injects list_changed from inside connect(), keeps a foreign namespace squatter in place, and proves activation still rejects after the notification's contained sync. Focused package coverage remains 100%, and the bilingual reconnect note records the ownership rule.
The MCP SDK starts a fire-and-forget close when initialization fails. Its stdio transport clears its process field before that close finishes, so our second Client.close() could return immediately and the reconnect timer could launch a replacement while the original child was still alive.
Track the transport onclose signal for every client generation and gate failed-attempt backoff on both Client.close() settlement and that signal. Use the same barrier during plugin disposal. If the SDK's bounded stdio termination window expires without onclose, fail closed and report incomplete shutdown instead of risking overlapping server processes.
Regression coverage models the SDK's early-returning second close, delayed and missing close signals, pending-connect disposal, close rejection, and the terminal timeout path. The reconnect Agent Note and Chinese counterpart now record the quiescence contract.
Integrate master at 8b4ef532 before addressing review feedback so each bot issue remains isolated in its own descendant commit. Resolve the vendor package rescope by moving the PR's new MCP supervisor imports to @deepseek-ai/cordis and @deepseek-ai/schemastery, preserve the reconnect implementation and e2e coverage, and regenerate the merged config and module catalogs with fresh bilingual pairing records.
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.
Two sites reached a registry for the vendored framework, which the rescope
turns from a silent second copy into a hard failure.
Live-link mode relinked only the root manifest, so a generated workspace member
— `plugins/*/package.json` — resolved its own dependencies from the registry
and installed upstream cordis beside this repository's vendored copy.
`LinkWorkspace.relinkNestedManifest()` relinks every nested generated manifest;
`peerDependencies` keeps its range because package managers reject a link spec
there.
The sandbox publish-path rehearsal installs this repository's vendored cordis
and cosmokit tarballs instead of naming a registry version.
Every harness package declares cordis as a peer dependency, so publishing the
harness publishes the vendored framework layer too; under the upstream names
that publication would squat them on the registry.
scripts/rescope-vendor.ts owns the rename: the nine-package mapping, a
delimited-token rule that leaves cordis.yml, the Loader's cordis: builtins and
vendor directory names alone, per-file exemptions where a name is a directory
or an upstream runtime identifier, and the exact edits for sites a token rule
cannot express — dot-notation lookups, unquoted manifest keys, a regex literal
whose failure would make every Context-merge scan silently find nothing, the
vendored-manifest table, and the contracts that told readers vendored packages
keep their upstream names.
Markdown follows the rename inside every fence, because a fence is code a
reader copies or configuration they mount, and in `docs/` prose as well, where
a sentence quoting a name teaches something this repository no longer resolves.
Prose elsewhere records what was true when it was written, and the same
spelling can mean something else: the Python SDK's `cordis` option, or the
unvendored `@cordisjs/plugin-http`. `docs/rescope.md` states both names on
purpose and is exempt.
exactEditState() classifies every exact edit as pending, applied, or invalid.
An insertion keeps its anchor and a deletion keeps its remainder, so each side
counts the form that survives: a duplicated insertion, a half-applied
replacement, and a deletion whose remainder moved are all invalid. The run
classifies every edit before writing anything and aborts on the first invalid
one, so a disagreement between the mapping and the tree cannot leave a
half-rescoped checkout; each write re-reads its file, because two edits can
target one. rescope-vendor.spec.ts pins those rejections, and --check asserts
the whole post-state from the hygiene gate, so CI owns the invariant.
--reverse restores the upstream names, verified as a round trip: reverse, then
apply, reproduces this tree byte for byte.
docs/rescope.md is the consumer-facing reference: the old-name/new-name table
with each package's role, what the rename deliberately leaves alone, the sites
callers must change, and the commands to apply, verify, and revert. The Agent
Note carries the decision and its consequences.
The rename itself lands in the next commit, produced by running the script.
The child session now shows the preset badge its parent shows, which is the
visible consequence of recording the composition it runs. The first recording
of these two goldens was taken against a dist built before the master merge,
so it captured the fallback Chinese label instead of the English one
`newEnglishPage` pins — the web lane replays the BUILT client, and a stale
build reads as a product difference. Re-recorded after `pnpm run build`.
