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 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.
A per-instance connection supervisor restarts the original server config
with exponential backoff when the transport closes, re-runs tool discovery
on success, and atomically replaces the previous generation. Default policy
retries for ~2.5 minutes (10 attempts, 500ms→30s doubling) before giving up
and unregistering the server's tools.
New config block reconnect { enabled, initialDelayMs, maxDelayMs, maxAttempts }
on both transports; misconfiguration fails plugin load. A connection that
survives past the stability window (maxDelayMs) resets the attempt budget,
so occasional crashes recover indefinitely while a crash loop still exhausts
the cap.
Integrates with the upstream failOnStartupError: the initial sync uses
registrationFailure:'throw' when that flag is set so a squatted namespace
still rejects activation.
Fixes#1746
Delete design-session citations (decision/audit/plan ordinals, stack
positions), change narration, review choreography, and reviewer-addressed
justification from comments, JSDoc, docs, READMEs, Agent Notes, tests, and
generator templates; restate every affected fact as current-state contract
prose. Fix generated docs at their sources and regenerate the catalogs and
cordis-surface regions; re-paste type-equiv blocks; update every bilingual
counterpart and re-record the pairs. Record the citation rule in the
committed-artifact-citations Agent Note.
Research across 8 multi-server agent clients (Claude Code, Codex, Gemini
CLI, VS Code, Cline, Roo Code, Goose, OpenCode) showed all of them keep
the server namespace in model-facing MCP tool names; the RFC's premise
for raw names ("servers already prefix their tools") is false for the
official GitHub/filesystem/Sentry servers.
- Config: drop toolPrefix; require serverName ([A-Za-z0-9_-]{1,32}),
duplicate serverName fails the later instance at load (per-root
reservation, released on dispose)
- Names: always mcp__<serverName>__<rawName>; normalize to the DeepSeek
64-char [A-Za-z0-9_-] contract with a deterministic 12-hex identity
hash on lossy normalization; raw name is the only thing sent on the
wire (tools/call)
- Sync: two-phase fetch/swap — fetch failure keeps the previous
generation; a swap conflict rolls back the whole generation (never a
partial set); duplicate raw names reject the tool list
- RFC: moved to implemented/ (status + skeleton rewritten per the
format contract), naming design + tier-level test coverage recorded
- Tests: naming algorithm unit suite; keyless Streamable HTTP e2e
against an in-process StreamableHTTPServerTransport (namespace
discovery, execution, per-request auth headers); dotted-name
normalization e2e via a new fixture tool

Addresses CI coverage gap: exercises the latest-wins resync coalescing
(pendingResync branch), the client.onclose callback, and ensures index.ts
is loaded without module mocks for stable v8 coverage across environments.
