Make the checked-in minimal SDK overlay disable both one-shot shell rows and mount exactly one persistent PTY stack: Bash on Linux/macOS and PowerShell on Windows. The SDK server, explicit dsh home, persistence, editor, timeout, and reduced tool catalog remain unchanged.
Update the runnable example and tutorial to list Windows x64 as supported, describe the platform-selected shell, and remove the obsolete POSIX-only restriction. This keeps the documented first Python task executable through the packaged Windows dsh profile instead of advertising a Linux-only overlay on a Windows-capable SDK.
Add node24-win-x64 as the only supported Windows runtime target and publish it as a py3-none-win_amd64 wheel containing the conventional dsh and ripgrep .exe payload names. Keep Windows ARM64 rejected explicitly so Python cannot claim a carrier that CI and release automation do not build.
Teach the pkg builder to require a native x64 Windows host, validate both node-pty ConPTY addons, copy @vscode's win32 ripgrep executable, and recognize pkg's .exe output. Extend runtime resolution, wheel staging, payload validation, and the preset closure check so the Windows-specific PowerShell plugins and sidecars fail loud when omitted.
The sidecar resolver now maps a packaged main.exe to main-rg.exe; focused TypeScript and Python tests cover that name, the win_amd64 manifest, x64-only host selection, complete wheel payload, ConPTY inventory, and platform-conditioned plugin closure.
Add a startup-only sdk-minimal template whose sole bundle inserts the complete JSON-RPC agent tree over the empty profile root. The roster is an explicit composition allowlist: it contains one DeepSeek adapter, the minimal agent spine, persistent Bash, the string-replace editor, local execution, and JSONL persistence, while dsh-base and Web remain absent.
Reuse the SDK app startup provider so the new profile retains help, stdin EOF, and bounded launcher shutdown semantics. Make that provider render its configured profile name, which keeps both sdk and sdk-minimal help truthful without duplicating process lifecycle code.
Register the package in the CLI closure, TypeScript graph, lockfile, Knip policy, and bilingual bundle references. Exact manifest, row-roster, profile-template, config-dump, and HMR tests make later additions visible instead of relying on a blacklist.
The packaged dsh launcher must expose installation modules to profile-local plugins without writing symlinks into pkg's virtual filesystem. The first review fix selected ESM exports correctly in ordinary Node, but real carrier execution exposed package metadata and VFS behavior that a synthetic tree did not cover: executable and declaration packages have no import entry, legacy main fields rely on Node probing, and pkg's Windows VFS prevents filesystem package-scope resolution from seeing exports such as zod/mini and @google/genai/web.
Resolve explicit exports directly from each installed manifest with the maintained resolve.exports package under Node import conditions. Publish only package-local candidate files that exist, reject escaping or malformed targets, preserve the package installation URL without realpath, and keep Node's legacy resolver only for exports-less packages. This avoids pkg filesystem package lookup entirely while retaining fail-loud behavior for broken runtime entries.
Add regression coverage for import-only, nested, symlinked, zod-style, and genai-style condition maps; unavailable and types-only entries; invalid and escaping targets; executable/declaration packages; extensionless main; and legacy index fallback. profile.ts remains at 100% statements, branches, functions, and lines. Update the bilingual package and Agent Note contracts, replace the runtime dependency and generated notice, and regenerate the lockfile through pnpm.
Resolve packaged profile proxies with Node ESM import conditions from each package installation, and fail loud when an explicit runtime export or legacy main entry is missing. Serialize the shared profile fallback under the existing cross-process writer lock so concurrent dsh processes cannot observe partial proxies; either carrier now replaces the other carrier’s managed entry without manual cleanup.
Give Python initialize its own 10-second default bound and name the selected profile in timeout diagnostics, while leaving ordinary agent turns unbounded by default. Package the dynamically resolved web frontend and skill-badge assets so the runtime wheel’s normal dsh profiles do not depend on pkg static-discovery accidents.
Rewrite the root launch rule and every active stale SDK-runtime note to the shipped dsh profile architecture in both languages. Focused tests prove import-only and transitive package exports, lock contention, cross-carrier transitions, missing-entry failures, asset inventory, and bounded initialization.
Make the zero-code dsh-python-runtime-closure depend on the real @deepseek-ai/dsh application and every required profile peer, then package apps/cli's built bin instead of the deleted Python carrier. Rename executables to deepseek-harness-sdk-runtime-<platform>-<arch>, update wheel/platform/build workflow discovery, and install a Python dsh console command that requires explicit DSH_HOME before exec.
Include profile, bundle, preset, native addon, and shared-library assets needed by the full CLI. Remove the checked-in default cordis.yml and preserve the existing wheel distribution names, Python module names, sidecar validation, and wire identity. Runtime resolution and release tests pin the new artifacts and dev Node carrier.
Unix PowerShell emits cursor-position requests while PSReadLine starts and
redraws prompts. The subprocess PTY is only a transport, so those requests
went unanswered. Startup could then accept the dsh> literal echoed from its
setup source as a rendered prompt, and later sends were lost or clipped.
Feed raw PTY output into a zero-scrollback @xterm/headless state machine and
write generated replies through the provider-owned terminal handle. Drain
replies before caller input, repeat foreground inspection when terminal
activity races the sample, and retain send ownership until parser and reply
work quiesce. Coalesce raw chunks behind one active parser write so large
Windows output cannot create thousands of queued parse callbacks.
Publish pwsh only from backend stdin_read evidence and start one timeoutMs
deadline before the complete startup retry loop, so inferred-idle follow-ups
cannot reset the bound. Dispose the emulator when the
terminal or cleanup fails. Document the fail-loud ConstrainedLanguage path
and add focused coverage for split queries, reply ordering, foreground
resampling, failure containment, batching, timeout, and disposal.
