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.
util/ — low-level shared utilities
English | 中文
Zero-dependency primitives shared across the other groups. A package lands here when it owns a tiny, foundational type or helper that several capability families need but that belongs to none of them — keeping it out of any one group avoids a capability package depending on an unrelated one just to reach a shared primitive. These are support packages: small, stable, and free of harness dependencies.
| Package | Role |
|---|---|
brand/ |
The type-only Branded<B> nominal-typing primitive (no runtime code, no harness deps) |
paths/ |
Canonical single-root DSH_HOME resolution plus shared filesystem path constants and helpers for harness user data (no harness deps) |
timeout/ |
The timing/classification half of a timeout — clampTimeout/deadline/timeoutOf/TimeoutReason (pure functions, no harness deps); termination stays in each capability |
retention/ |
Bounded model-facing output — ItemRetainer/TextRetainer + neutral notice helpers (pure, no harness deps); business semantics stay in each tool |
native-command/ |
No-shell execFile runner for host-native OS integrations — utf8 capture, abort propagation, Windows hide (no harness deps); command choice stays in each caller |
dsh-brand is the canonical case: it owns ONLY the Branded<B> helper, so a capability package can brand the ids it owns (dsh-tasks's TaskId, dsh-session's SessionId, …) by depending on dsh-brand alone, without pulling in an unrelated package just to reach Branded.
dsh-paths gives every package the same configurable Harness home without assigning that cross-cutting fact to bash, skills, telemetry, or a composition bundle. It resolves an explicit value before $DSH_HOME, falls back to ~/.dsh, and returns an absolute path without caching, creating, or mutating anything. The harness keeps all user data under one root.
dsh-timeout follows the same shape for the timeout family: dsh-bash and dsh-web-fetch-local each fuse a caller's cancellation with a deadline and later classify "timed out" vs "cancelled" by depending on dsh-timeout alone. It deliberately owns only the timing/classification half — the termination (SIGKILL a process group, tear down a fetch socket) stays in each capability, because no shared layer can own every capability's kill (see the timeout-library Agent Note).
dsh-retention is the same split for bounded tool output: a tool (glob/grep/bash/web_fetch/web_search) feeds items or text into a retainer and gets back what it kept and exactly what it omitted — while grouping, exit codes, provider errors, and recovery prose stay tool-owned. It deliberately owns only the retention mechanic; truncated is a budget fact, never an "incomplete inspection" state (see the retention-library Agent Note).
