Baseline moves to DSH 0.1.5-alpha.2 only (peer floor ^0.1.5-alpha.2,
CI pin, manifest engines); alpha.1 users stay on v0.19.0-alpha.0.
Host-contract changes handled:
- the native guide entry lost its `description` field (entries are
icon+title capsules now): `TabDescriptor.description` and the six
`guideDesc*` keys plus the `nativeGuideDesc` fallback are removed.
- the file address grammar changed: `fileAddressFor` always returns a
session-scoped address (absolute paths keep their leading `/`),
`parseFileAddress` is prefix-based and strips `?`/`#`. The plugin's
purity-gated mirror follows.
- global main panels replaced the `conversation` root slot with the
keyed `main` slot (`main.conversation`): the bottom workbench's
center-column locator now accepts both keys and skips
`display: contents` slot hosts.
Fixes a pre-existing fill bug the alpha.2 probe made obvious: the native
tab body host is a block scroller with a definite height, so tab roots
that only declared `flex: 1` collapsed to content height and the side
chat composer drifted off the pane bottom. The native adapter now wraps
every tab body in a `height: 100%` column flex host.
Also promotes the dependencies `dsh-client-ui-primitives@0.1.5-alpha.2`
dropped from its manifest (anser / shiki / mdast-util-* / micromark-* /
katex / @shikijs/langs) and the newly unmet `dsh-session-persistence`
peer into devDependencies.
The native new-tab list rendered one generic line ("opens in the DSH
sidebar") under every plugin entry, so six plugin rows read identically.
`TabDescriptor.description` now carries the real purpose (string or
locale-following thunk; absent falls back to the generic line), and the
six visible builtins declare theirs across all 20 dictionaries.
- service.ts: `TabDescriptor.description` + docs (guide §4.1, §0 row).
- native/: the guide entry's description follows the descriptor; the
`files` takeover reuses the editor's line.
- builtins: files / changes / tasks / side chat / terminal / browser.
- tests: builtins assert every visible type declares a distinct line;
the lifecycle test asserts descriptor lines (and the takeover reuse).
DSH 0.1.5 owns the right column (its native Sidebar hosts every tab type
this plugin registers), so the plugin's own right panel, its width drag /
new-session seed prefs, and the free-window feature are gone. The bottom
workbench is the only plugin-owned surface left, and its expand/collapse
control is registered into DSH's session-header utilities list slot (the
header's corner seat belongs to the native sidebar's own control).
- state: one `bottomSplits` tree; `makeDefaultState()` takes no arguments;
`toggleBottomPanel` / `openTabInBottomPane` are the only landing
reducers; `setBottomHeight` and `sanitizeState` share the
`CONVERSATION_MIN` cap (a persisted tall height no longer snaps on the
first drag).
- service: every landing in the workbench (creation or focus) expands it;
`SIDEBAR_FEATURES` drops `'floatWindows'`; the open/close/activate tab
pools cover the single tree.
- shell: `Sidebar.tsx` renders only the bottom workbench; the toggle lives
in `sidebar/bottom-toggle.tsx`; layout-push pushes height only (no width,
no `--dsh-sidebar-width`).
- prefs: `openByDefault` / `defaultWidthPercent` / `changesDiffFloat`
removed from the schema, defaults, client parser, settings page, and all
20 dictionaries; the retired keys in stored documents are ignored.
- tests: free-window specs deleted, panel/float assertions dropped,
remaining suites adapted (124 files / 1287 tests); the mount lane asserts
the header toggle and sweeps the native sidebar's guide page.
- docs: README / README_EN / guide §0,§11 / AGENTS test map.
The guide renders `entry.icon`, and the `files` kind takeover registered
without one — so after the editor type stopped contributing its own
duplicate row (b56ceec), the single "Files" row was the only entry in the
new-tab list with a blank icon slot. The takeover now carries the editor
descriptor's icon (the takeover IS that descriptor's page).
Extracted `guideIconOf` so both registration sites build the icon field
the same way; the lifecycle test asserts the takeover's guide entry has
an icon.
The editor type's page identity IS the `files` kind takeover (same
explorer, same title), so the guide/new-tab list showed two identical
"Files" entries — observed on a real profile after the takeover landed.
The editor type now contributes no guide entry of its own; it stays
registered as the file RESOURCE viewer. Covered by the registration
lifecycle test (editor: no guide, files takeover: guide).
The editor type serves both the files PAGE and every file RESOURCE; its
native `title` callback ignored the address, so every opened file showed
up in the strip as "Files" — indistinguishable tabs. Verified on a real
profile: after opening `AGENTS.md` from the tree and a chat file link,
the strip read ["文件", "文件", "文件"].
`title(address)` now returns the file name for a file address and keeps
the descriptor title for a page address (`sidebar://editor`). Covered by
the registration-lifecycle test in tests/native-surface.spec.ts.
The native seat declares `sidebar.right.pane.tab` BEFORE it provides
`sidebarRightTabs`, so driving the registration off the slot declaration
read the service as missing and registered nothing — permanently, since a
declaration never collapses. Observed on a real DSH profile (0.1.5-alpha.1,
`dsh web` on the web profile): the plugin host and its other slot
registrations mounted, the native guide page stayed empty, and a probe
printed `sidebarRightTabs= undefined` at declaration time with the registry
present three seconds later. The scratch mount lane never saw it because
there the plugin activates after the native package finished providing.
`registerNativeSurface` now waits on the SERVICE (`ctx.inject`), which
re-runs whenever the registry appears/reappears, and keeps the per-body
slot registrations on `slots.inject` (they only need the declaration).
Regression test: `tests/native-surface.spec.ts` models the real order
(slot callback fires first, registry arrives later) and fails on the old
implementation. Verified on the real web profile: all guide entries
(files / editor / git / subagent / sidechat / terminal / browser) appear
and the terminal tab renders.
TabDescriptor requires `component`; the fixture omitted it, so CI's
typecheck step failed on the phase-2 branch (vitest never compiled the
file's props strictly, so the local run stayed green).
Phase 2 of the 0.1.5 adaptation: the plugin stops drawing its own right
panel and contributes tab TYPES to DSH's native right Sidebar, which owns
the right column. The bottom workbench (terminal dock) stays plugin-owned.
Registrations (src/client/native/):
- every TabDescriptor becomes a native tab type (kind = descriptor.id, the
default `extension` band) plus a keyed body in `sidebar.right.pane.tab`
and a live chip title in `sidebar.right.pane.tab.title`
- the `editor` type also claims `dsh-resource://file/**`, so it outranks
the built-in `text` preview (fallback) and every file the product opens
lands in the plugin's editor
- the built-in `files` page kind is TAKEN OVER by an extension
registration of the same kind: `openTab('files')` draws the plugin's
explorer, and the built-in resumes when the plugin unregisters
- registrations follow the plugin registry + the side-card settings: a
type registered later (external plugin) gets its native type too, a
disabled type is unregistered (absent from the guide, refuses opens)
Adapter (src/client/native/tab-adapter.tsx):
- one synthetic plugin `SidebarTab` per native tab id, minted from the
native record + navigation params (or the descriptor's own createTab,
which a native guide open bypasses), kept live across navigations and
updateTab writes
- the explorer's per-tab expansion/reveal sets and the per-kind instance
counter, which the plugin's own layout used to hold
Service routing (src/client/service.ts):
- `setSurface` installs the native write face; openTab/openFile land
natively (a path becomes a resource address, a path-less editor open
becomes the `files` page, the rest carry the seed as navigation params),
closeTab/updateTab/activateTab recognise native tab ids
- new optional `OpenTabSeed.target` ('right' default, 'bottom' keeps the
bottom workbench); the bottom panel's own + menu and auto-terminal pass
'bottom'
- src/client/native/surface.ts probes the controller's per-session writes
(`openTabIn`/`openResourceIn`/`closeIn`, not in `ISidebarRight`) and
queues opens for a session whose surface is not mounted yet
Right panel retired behaviourally (Phase 3 deletes the code): Sidebar
renders its bottom workbench only, keeps the panel collapsed, and hides
the right-panel toggle. The panel-specific e2e specs are removed; the
mount lane now drives the native guide (tab sweep), the plugin explorer
inside the native pane (editor/mermaid/README chunks) and the sidechat
host routes.
Verified: pnpm typecheck / lint / build / test (126 files, 1349 tests) /
check:consumer-types, plus pnpm test:mount against a real
@deepseek-ai/dsh@0.1.5-alpha.1 host (7/7).
Move the plugin onto the DSH 0.1.5-alpha.1 baseline (peer floor
^0.1.5-alpha.1, CI pinned to the alpha dist-tag) and fix the two host
contract changes that alpha line introduced.
Baseline:
- all @deepseek-ai/dsh-* peer/dev deps -> 0.1.5-alpha.1; optional peer
@deepseek-ai/dsh-client-ui-sidebar-right (declared, unused until the
native-surface phase); devDep @deepseek-ai/dsh-agent-loop (inbox fold)
- dsh.plugin.json engines >=0.1.5-alpha.1; version 0.19.0-alpha.0;
SIDEBAR_SERVICE_VERSION follows
Live assistant stream (assistant/chunk is gone):
- 0.1.5 publishes in-flight model deltas as process-local
agent/assistant-stream frames instead of durable assistant/chunk events
and embeds the settled stream in assistant/message / assistant/attempt.
src/assistant-live.ts folds the frames into a bounded per-session buffer;
sidechat.events serves the current attempt as `live` rows (replaced every
poll, never a delta) and the transcript renders them; the inherited
in-progress snapshot reads message content / attempt stream / live frames.
Cold session reads (persistence.inspect is gone):
- 0.1.5 reads a stored session through an explicit read handle
(open(id,'read') -> handle.read() -> close()). src/session-store.ts owns
that protocol; every cold read (sidechat transcript, cold-resume preset,
session.cwd, changes replay) goes through it.
Dead code and docs:
- drop the remote.session.openWorkspacePath interception: 0.1.5's chat opens
files through ctx.sidebarRight.openResource instead, so the wrapper had no
caller and would hijack the host's "open in app" gesture; the
interceptOpenPath pref, its settings row and its locale keys go with it
- AGENTS.md §3 + external-plugin-guide.md describe the new baseline
- vitest setup bridges Node's localStorage accessor to jsdom's store (the
pre-existing 26 failures on Node >= 22)
- desktop-layout e2e seeds through host RPC and types into the Lexical
composer (0.1.5 replaced the textarea) instead of driving the directory
picker
Verified: pnpm typecheck / lint / build / test (124 files, 1327 tests) /
check:consumer-types, plus pnpm test:mount against a real
@deepseek-ai/dsh@0.1.5-alpha.1 host (18/18).
