creatixchu 85ca8be104 feat(host,client): compose directory picking through slots — dual-face -native, no wire advertisement
ui-workspace's two trigger surfaces each declare a single-kind directory-flow
hole (conversation.hero.workspace.directoryFlow / sidebar.workspaces.directoryFlow,
same owner contract) and keep only the trigger and the adoption: the Open-local-
folder entry renders while the surface's hole is occupied, and the occupant
reports one picked path per open through the hole's owner conversation
(open/busy/onPicked/onCancel/onError).

directory-picker-native becomes dual-face: its browser half fills both holes
with a renderless occupant driving host.pickDirectory, so the cordis.yml row
that mounts the backend also composes the client interaction — a mismatch is
impossible and a second flow package fails at client load.

With composition wiring both sides, the host.describe.directoryPicker
advertisement and the client's kind branching lose their last consumer:
the field, WorkspacesService.directoryPickerKind(), the DirectoryPickerKind
wire type, and the picker's per-open describe read are deleted. The connection
fixture now serves a deterministic pickDirectory path so the keyless snapshot
drives the full pick-then-adopt flow. ui-workspace's hand-rolled declaration
deferral is replaced by the deferRegistration helper it duplicated.

dsh-native-command

English | 中文

A zero-dependency no-shell execFile runner shared by host-native OS integrations: one runNativeCommand(command, args, signal) call spawns the executable directly (never a shell string), captures utf8 stdout/stderr, propagates the caller's abort into child termination, and hides the transient console window on Windows. Failures reject with the exit code and both captured streams attached, so callers classify (missing tool, cancelled, real failure) without re-running anything.

Its two consumers are the host-side native integrations: the directory-picker-native backend's OS chooser commands and the gateway's open-with-default-application hand-off (dsh-host-apiproxy host.openPath). The NativeCommandRunner type is the injectable command boundary those callers expose for deterministic tests.

It is a library, not a service or plugin: no ctx, registers nothing, holds no state, emits no events.

Surface

import { runNativeCommand, type NativeCommandRunner } from '@deepseek-ai/dsh-native-command'

Model Experience

None, as this is host-side subprocess plumbing; nothing here reaches a model request.

KV Cache effect

None; this package neither assembles nor sends a provider request.

Known Limitations and Deferred Work

  • No output bounding — both streams buffer unbounded in memory; every current caller invokes small native tools whose output is a path or an error line. Adopt dsh-retention bounding before pointing this at commands with meaningful output volume.
