Scope decision: previews for a browser that is not on the Host machine are not supported. With that settled, host.openPath answers the supported case completely — a file:// document in a real browser has full page capabilities and no reach into /api — and the HTTP serving this branch had built answered only the unsupported one. Removed: the /f route and its listener, the workspace-file URL shape, ApiProxy.workspaceRootOf, ConnectionHandle.fileUrl, and the port published into the index page. Kept, and finished: - the produced-files row a turn ends with, derived from mutation locations; - the path link now reads as a link at rest, not only on hover — the reported "I can't open what it made" was this, sitting on a working capability; - the Host opener prefers the default BROWSER for .html/.htm/.xhtml/.svg, so a developer who binds .html to an editor still gets a rendered page (macOS via the LaunchServices https handler, Linux via $BROWSER, every failure falling back to the default application). The retired designs and their measurements stay in the Agent Note, including why same-origin serving was unsafe and why the sandbox that fixed it broke the pages invisibly.

jsdom slot test runtime for client feature specs: a real Cordis Context, the production SlotsService and web-react renderer, assembled around typed session/workspace doubles. Feature suites exercise declaration, registration, scope, store, inject, rendering, updates, and disposal without hand-building the machinery per suite — and without a second implementation of any production logic.
The doubles implement the same outward faces features receive through ctx (TestSessions implements ISessions, TestWorkspaces implements IWorkspaces; each fixture session is a FixtureSession implements SessionFace), so a production face change breaks the bench at compile time instead of silently drifting. Provide-bundle materialization runs the production SessionProvideChannel — the one implementation shared with SessionsService. Fixtures feed plain data: list rows, conversation snapshots (immer-patched via updateSnapshot), projection values, and ISession-typed behavior stubs that fail loud when a spec calls an unstubbed verb. The typed provide() constrains fakes for declared service names to Partial of that service's outward face.
Local DOM snapshots: declare(children) registers an auto frame whose per-key <div data-slot> wrappers are snapshot roots; renderSlot(key, owner) returns the slot-local view (container, scoped Testing Library queries, in-place update(owner)); a registered snapshot serializer folds CSS-module class hashes (_frame_a1b2c3 → frame) to keep .snap files structural and collapses <svg> internals to a data-content fingerprint. Suites needing a custom page frame use root.declare(children, Frame) instead; mount(plugin) runs a real fiber with fail-loud service prechecks, and dispose() tears down views, feature fibers, minted scopes, and persisted store state on one axis.
Not part of the product plugin graph (no dshClient); feature packages depend on it in devDependencies only.
Model Experience
None, as this package is browser-side test infrastructure; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Consumed through repository source aliases only. Specs resolve the package through tsconfig
pathstosrc; the builtlib/artifact re-exports@deepseek-ai/dsh-client-runtime/client, whose bundle is a browser loader script with no Node ESM exports, solib/index.jsis not importable under plain Node. Acceptable while every consumer is an in-repo Vitest suite; a Node-compatible runtime entry is deferred until an out-of-repo consumer exists. - Conversation snapshots are fixture data, not replayed history.
updateSnapshotwrites the snapshot store directly; the wire-to-snapshot computation stays covered by the runtime package's own tests and the replay e2e. A fixture can therefore express states the production projection would never produce.
