DSH 0.1.7-alpha.1 is 1299 commits past 0.1.6-alpha.2 and rewrites four
contracts this plugin was built on. The peer floor moves to
^0.1.7-alpha.1 (semver's prerelease rule means ^0.1.6-alpha.2 can never
match a 0.1.7 prerelease); 0.1.6-alpha.2 and earlier stay on v0.19.1.
Released as 0.21.0-alpha.1 (dist-tag alpha).
Hard breaks:
- dsh-settings was rewritten: register(ns, schema) is gone, a form is
addressed by the plugin row's Loader entry id and read from the
module's exported Config. The preferences are merged into Config and
marked volatile — which requires DSH's own schemastery, because only
that build wraps a volatile field in the cosmokit reference the
loader's volatile commit walks. With the public package a settings
write reports success and revision 1 while the effective value never
changes.
- ui-primitives renamed its whole icon family (IconXxx14/16 ->
IconXxxRegular/Medium): 26 imported symbols, 17 files. The failing
mode is render-time, not load-time. Five call sites that relied on the
old 14px default now pass size={14} explicitly.
- Session format v4 rejects source.kind === 'plugin'; the side-chat
boundary injection now writes plugin:dsh-better-sidebar, the same kind
DSH's own v3->v4 migration produces, so historical threads survive.
Tool results moved to role 'tool' with top-level content/isError; all
four parsers accept both shapes.
- The client session snapshot dropped subagentsByParent/jobsBySession
and the on-demand subagent-catalog observation API. The Tasks page
reads projectionsBySession and a new jobs.list route.
Yields and convergence:
- The read-only previews go to DSH's documentpreview (Office->PDF, a
spreadsheet worker, zoom, per-directory refresh); editor.canOpen
refuses those 26 extensions. Markdown, HTML (with its sandbox
switches) and the editable code buffer stay.
- The host browser kind is desktop-profile-only now, so the web e2e
lanes expect no browser entry and assert its absence.
- Link takeover claims only urlTarget links and passes the rest to the
host, fixing a regression from the 0.1.6 round: the fallback pointed
at a 'browser' type the plugin no longer registers, so http links in
its own markdown did nothing.
Also fixed, found along the way:
- The file tree refreshes live (new directory watch over the plugin's
own socket), since the plugin owns the `files` kind.
- ctx.sessions.list has no `current` field at either tag; the three
readers were dead. They now use ctx.sidebarRight.mounted.
- package.json.files was missing lib/client-locale.js.
- Two genuinely dead call sites: sessions.openSubagent/open/
refreshSubagents do not exist on the current baseline, so the
topology click, the jump-back and the retry were all no-ops.
- The test harness window shim lacked addEventListener, which the 0.1.7
primitives call at module-evaluation time; and the e2e token exchange
needs Playwright's request stack, not Node's fetch.
DSH 0.1.6-alpha.2 ships a right-Sidebar terminal and a right-Sidebar browser
of its own. Both were things this plugin had built from scratch, so keeping
them meant two implementations of one surface plus a plugin that shadows a
host type the product is actively developing.
Terminal: the plugin's whole PTY stack goes — the UI-tab manager, the
agent-owned registry, the lazy node-pty loader, the eight model-facing
terminal_* tools, the xterm view and its font/link/scrollback helpers, and
the cross-session 'pinned terminal' rail that existed only to keep a terminal
alive across a session switch. The host's terminal kind becomes the only
provider, which also retires the node-pty dependency, its pnpm allowBuilds
entry, and the installer's -Repair mode (issue #140's whole class of
'node-pty failed to load' support).
Model-facing capability note: the plugin used to inject terminal_* tools
(off by default). Those are the model's only cross-call persistent terminal,
and DSH's own equivalent (@deepseek-ai/dsh-tool-terminal) is not mounted by
any shipped bundle, so removing them leaves the model with the one-shot
bash/pwsh tools only. That is the accepted cost of not maintaining a second
PTY surface; the README documents how to enable the upstream toolset.
Browser: the plugin's browser tab type is dropped, so the host's own browser
kind owns embedded pages. The DOM-level link takeover STAYS (it is the only
thing that can route an https link to the system browser by protocol, which
the host does not do) but now delegates to the host's browser tab via
ctx.sidebarRight.openTab('browser', …) with a window.open fallback, and the
two settings that only ever configured the plugin's own iframe (sandbox
escape hatch, loopback allowlist) go with it — along with the host-side
browser.probe route they fed.
Cards: the empty-pane welcome cards adopt the host's guide-capsule recipe
(0.5px l4 hairline, 24px radius, layer-1 fill, 56px floor, 14px/20px padding)
so the plugin's 'pick what opens here' surface reads as the same design as
DSH's own. A theme.spec guard pins the geometry and the token-only paint —
including that the upstream-only --dsw-alias-bg-l1/-l2 spellings (defined
nowhere, so their declarations are silently dropped upstream) never appear
here.
Also drops the dead state the removed features left behind (SidebarTab.pin,
nextTerminal, agentWaits, bottomOpenedOnce, the agent-tab helpers, the
pinned-tab memo key), re-points every test fixture that used them at
surviving equivalents, and prunes the specs of the deleted features.
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.
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).
getEntriesByType widens to PerformanceEntry; transferSize/
decodedBodySize live on PerformanceResourceTiming (the e2e specs sit
outside tsconfig.build.json, so the bundler never saw this).
A measurement harness, not a pass/fail gate (beyond the mount sanity
it shares with the other lanes): an init-script probe samples the
navigationStart → host-attach latency, a longtask collector runs
through the full built-in tab sweep, sidebar-shaped resource entries
report transfer/decoded/duration, and a frame sampler records the
bottom-strip drag's pacing (p50/p95/max) plus the width-leak guard.
Results print as single-line PERF_JSON records so a shell run can tee
and grep them; before/after comparisons land in
docs/plans/2026-08-31-perf-optimization.md. Baseline (main @ d70db8f,
3 runs): mount ≈ 377ms, 2 longtasks ≈ 161ms, drag p95 = 10ms,
width leak = 504px.
