The alpha.1 handover refused 27 extensions so DSH's own document preview
could own them, but nine of those have NO host renderer at all: `avif` and
`ods` sit in `document/unviewable.ts`'s "known binary, no renderer" list
and get the unsupported empty state directly, while `xlsb` / `xlt` /
`xltx` / `xltm` / `ots` / `dot` / `dotx` fall through to the plain-text
body, fail the binary check and land on the same dead end.
Before that handover these files reached the plugin's `code` catch-all and
rendered the binary-download pane, so refusing them was a user-visible
regression we introduced ourselves — and rc.1 did not restore it. They are
claimed again (`fods` stays handed over: the host shows that flat XML as
plain text, which beats a download pane).
`canOpen` had zero test coverage, which is exactly why the regression went
unnoticed, so `tests/native-surface.spec.ts` now pins both directions:
every format the host renders must be refused, every format it cannot
render must be claimed. Reverting to the old list makes it fail with
`macro.xlsb: expected false to be true`.
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 0.1.6-alpha.2 made two plugin-facing contracts stricter, and both broke
this plugin silently:
- `SidebarRightGuideEntry.id` is now required and unique per provider. The
native tab registrations sent guide entries without one, so the second kind
collided on `undefined` and `SidebarRightTabRegistry.register` threw
'duplicate guide entry id'. The throw happens inside `ctx.inject`'s callback
body, which cordis swallows, so the whole native surface stayed empty with no
symptom beyond a missing guide row.
- `conversation.chat.turnTail` changed from a `chain` to an additive `list`.
The chain's `select` made one entry render and let this plugin REPLACE the
host's produced-files row; a list cannot express that, and the registration
now throws 'list slot ... requires options.id'. Upstream chose the list
deliberately ('An additive list lets both plugins contribute without either
knowing the other's data or rendering'), so the plugin's row can only ever
duplicate the host's deliverables row -- which itself opens files through the
host's openFile, i.e. into this plugin's editor. The contribution is removed
and the row is the host's alone.
The file-opening half survives as `sidebar-file.ts` (the changes tab and the
editor host still use it), and `resolveSidebarPath` moves to the `paths.ts`
path-helper module beside its siblings. `registerNativeSurface` grows an
optional `reportFailure` so a future contract break reaches the visible
diagnostic strip instead of a silently empty guide, and one bad descriptor can
no longer take the remaining registrations down with it.
The native openTab branch rerouted EVERY path seed into openResource (a
dsh-resource://file/... open) without looking at seed.type, so any
component tab opened with a path landed in the editor (the only
dsh-resource://file/** claimant) and its registered component never
mounted. This also contradicted the guide, whose TabDescriptor/openTab
contract and WebDocsView example document path-seed component tabs.
Route by type instead: only the editor kind (the only registration with
dsh-resource://file/** patterns) turns its path seeds into resource
opens; every other kind keeps the page open and carries the path in the
navigation params, which NativeTabRecords.ensure already merges back
onto the synthetic record's tab.path for the component. The bottom
workbench path is untouched, editor opens behave exactly as before, and
onOpen still receives the synthetic tab with the path seed.
Issue #611 asked for file-type icons like the official explorer's, and #429
built a colored theme for them. DSH 0.1.5-rc.2 makes most of that work
unnecessary: `@deepseek-ai/dsh-client-ui-primitives` now exports
`FileTypeIcon` / `CodeFileIcon` with the host's own 48-type full-color code
artwork plus category-colored sheet glyphs (and its classifier behind them).
So the plugin renders the host's icons instead of shipping a color table, and
color becomes the only behaviour rather than an opt-in theme.
File icons (src/client/file-icons.tsx)
- `builtinFileIcon(path, size)` → `<FileTypeIcon path size />`; folders use the
host's folder category. The plugin's own per-extension VSCodicon map is gone.
- The public `registerFileIcon` API from #531 is unchanged and still outranks
the built-ins, so an external plugin can take over any row. One semantic
consequence, now documented and tested: because the host classifier covers
every path, a registered catch-all (`exts: []`) claims rows it used to lose
to the built-in map. An unregistered catch-all (the old icon theme's shape)
is unaffected.
- Nothing is lazy any more: the artwork lives in a platform module the client
already holds, so `lib/client-file-icons.js` and its 563-entry dataset (255
kB) are deleted outright — the core bundle grew by 10 kB (0.85 → 0.86 MB).
- `src/client/file-icon-theme.ts`, the `fileIconTheme` pref (prefs-shared /
config / client prefs), the settings-page select row and the six
`settingsFileIconTheme*` keys in all 20 dictionaries are removed with it.
Tab glyphs (src/client/builtins/tab-icons.tsx)
- Every built-in tab type now declares a colored glyph: files (the host's
folder artwork), changes/diff (commit), tasks (checklist), side chat
(discussion), terminal (shell), browser (globe).
- The color comes from a `--dsw-alias-*` token through a wrapper class, never
from a literal — the skin contract (§12) holds and `tests/theme.spec.ts`
enforces both halves (no literals in the module, every color declaration in
the stylesheet resolves to a token).
Native right Sidebar chips (src/client/native/tab-adapter.tsx)
- The host's tab definition has no icon field, but the
`sidebar.right.pane.tab.title` slot IS the chip's content, so the plugin
draws the glyph itself: an editor tab with a path shows that file's icon,
every other tab shows its descriptor's icon — the same `descriptor.icon` the
workbench strip and the guide capsules already render, so the three cannot
drift. The glyph is `aria-hidden`, which keeps the chip's accessible name
exactly the title the mount lane matches on.
Gates: typecheck / lint / check:consumer-types green; pnpm test 127 files /
1342 passed / 9 skipped (3 new chip cases, 1 rewritten built-in case).
- docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md: the adaptation plan —
the upstream rc.1 -> rc.2 delta per affected area, why there is no
plugin-side code change, and the CI failure taxonomy (A real Windows
timeouts, B the two silent worker deaths, C the mount lane's npm
ETARGET/OOM) with the evidence and the fix for each.
- AGENTS.md §2/§3: CI pins rc.2, the mount lane's npm flags and their reason
(floating transitives + staged prerelease publishing), the Windows lane's
bounded pool and why, and the primitives-dependencies note extended to rc.2.
- README.md / README_EN.md: support badge (v0.19.1, verified on rc.2), the
install section's stable-release note (rc.1 hosts need no upgrade — the peer
floor is unchanged) and a v0.19.1 changelog entry covering the two CI fixes.
- docs/external-plugin-guide.md: baseline line -> v0.19.1 / DSH 0.1.5-rc.1+,
verified on rc.2.
- Comment-only: `DSH 0.1.5-rc.1` -> `0.1.5-rc.1+` where the note describes a
behaviour that arrived in rc.1 and is unchanged in rc.2 (native guide
description rendering, in src/client/native/index.ts, src/client/service.ts
and the three specs that assert it).
Baseline moves to DSH 0.1.5-rc.1 — the 0.1.5 line's first release
candidate, and the npm `latest` dist-tag now: peer floor ^0.1.5-rc.1,
devDependency pins, the CI mount-lane pin and dsh.plugin.json engines
all follow. 0.1.5-alpha.2 users stay on v0.19.0-alpha.1.
The upstream delta from alpha.2 is small: 373 changed files, mostly
version bumps, sidebar preview polish and test snapshots. Exactly two
changes touch this plugin, and only one needs work:
- `SidebarRightGuideEntry.description` is back (optional). The native
guide renders it only while it lists at most 4 entries; a longer list
drops every description. The plugin restores `TabDescriptor.description`
and the six built-in `guideDesc*` lines (20 dictionaries) verbatim from
0b6ac5d^, but deliberately does NOT restore the old generic
`nativeGuideDesc` fallback: the host has no fallback of its own, so a
descriptor that declares none now ships no `description` field at all
and renders as a clean title-only capsule.
Consequence worth knowing: the plugin contributes six guide entries, so
the default composition is over the 4-entry limit and shows titles only.
The mount lane proves the restored field end to end by shrinking the
enabled set to three types through the plugin's own settings route
(scratch profile only) and requiring the Files capsule to grow its line.
- The built-in `files` type declares a guide description again and uses a
coloured folder glyph; the plugin owns that kind, so nothing to do.
Verified unchanged from alpha.2 (so nobody re-checks them): the global
main-panel model, the file address grammar (util/workspace-path changed
only its package.json), the native tab-body host contract (.paneBody is
still a block scroller with a definite height), the core/agent/session/
subagent host APIs and the ui-primitives export surface.
Restore caveat fixed in the lane: the settings route merges patches
key-wise, so undoing a temporary `tabsEnabled` change by posting the
original (empty) map leaves the disabled keys behind — the e2e restores
every key it touched explicitly.
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).
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).
