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).
Escape the .pdf extension in the op-target regex (the unescaped /.pdf$/
matched any path ending in pdf) and fold the copy-pasted toggle button
into PaneToggle; record the sixth deliverable in the design doc.
Records the five features shipped on this PR (md reading mode incl.
mermaid, highlight expansion, secret redaction, html render mode), their
deliberate boundaries (redaction heuristics, saved-file render
semantics), and the 2026-09-06 standards pass.
sidechat.start passed `seed` without `meta.isSeeded: true` +
`inheritedEventCount`, so dsh-session treated the whole seed as the
child's OWN events and the child's Inbox constructor replayed the
parent's `agent/inbox/spliced` history — inheriting whatever input sat
UNCLAIMED in the parent at the click moment:
- next-turn: a queued follow-up behind a still-running turn;
- next-step (the reported long-context case, parent queue empty): a
tool-result context / steering spliced between step boundaries.
The first side prompt then claimed [phantom, boundary, question] — the
stale parent message was sent to the model BEFORE the boundary and
logged as a user/message. The fix passes the exact marker pair the
host's own session.fork uses (api-session-controller); ownEvents() now
stops at the end-seed boundary and the inherited inbox replays empty.
Regression tests run the REAL Session.create + Inbox in both
directions (old shape inherits the phantom, marked shape stays empty);
routes tests pin the two create options. Verified: pnpm typecheck /
test (5 pre-existing unrelated UI-spec failures on main unchanged) /
build.
Graduate from the alpha track to the stable channel:
- Baseline: CI mount pin, dsh.plugin.json engines floor, and every
@deepseek-ai/* peer floor / devDependencies pin move to 0.1.2-rc.1
(published on the `next` dist-tag). alpha.5 -> rc.1 is a pure version
bump in the harness (all package.json "version" lines, zero source
delta), so no code adaptation; every host contract was re-verified
unchanged and the real-host mount smoke passes.
- dsh-client-locale resumed publishing; its trailing-pin exception is
gone — peers and devDeps align at 0.1.2-rc.1 (pnpm peers check clean).
- Version: fold the unpublished v0.18.1-alpha.0 / v0.19.0-alpha.0 bumps
into the v0.18.0 stable release; SIDEBAR_SERVICE_VERSION follows
package.json (asserted by tests/service.spec.ts).
- Docs: README/README_EN badges + channel notes + a full "since v0.17.1"
changelog entry (the two folded alpha numbers are annotated), AGENTS.md
§2/§3 baseline wording, external-plugin-guide version line, and the
e2e-host-protocol header's re-verified list gains 0.1.2-rc.1.
Three preview (render) bugs where DSH's chat-optimized markdown primitives
leak into the file-preview scroll world:
- CodeBlock banner: DSH's bannerWrap is position:sticky (top:0, z-index:6) so a
block keeps its copy action reachable inside a per-message scroll container.
In the preview every fence shares one .editorMd scroll container, so the
banner pins to the viewport top until the whole block scrolls past and reads
as a floating header. Neutralize stickiness for non-mermaid fences in the
preview (mermaid chrome replaces the banner and is excluded via
data-mermaid-processed).
- TOC popover z-index: .tocBar was z-index:3, below the code banner's 6, so the
outline panel painted beneath a sticky fence header. Raise the bar to 7.
- TOC dismissal: only the toggle re-click closed the popover. Add a document
pointerdown listener that closes on an outside press (blank preview space),
exempting the button and panel so the toggle still flips.
Adds md-toc unit coverage for outside-click dismiss and toggle-preserving
behavior; records the deviations in the TOC design doc.
shift fix) — but as a BARE declaration. Engines without clip support
(Safari < 16, older Chromium) drop an unsupported declaration at parse
time, which leaves the host `overflow: visible`: no clipping at all,
and the historical "collapsed panels extend the document's scrollable
area, whole page draggable" regression returns on those engines.
Declare `overflow: hidden` BEFORE `overflow: clip`: clip-aware engines
apply the later clip (identical behavior to #453), while old engines
fall back to hidden and keep clipping (with its pre-clip
scrollability — the same state they had before #453, strictly better
than visible). The cascade order is the contract.
Also extends the rule comment (the fix guards the whole
scroll-into-view class — focus moving into off-viewport regions,
nested iframes/workbenches claiming focus while loading — not just the
reveal case) and adds tests/panel-host-css.spec.ts guarding the
cascade (hidden first, clip last), the fixed viewport layer, and that
the degraded rule never reintroduces overflow. Contract documented in
the integration guide §12 (root anchor bullet).
- pins: CI mount-gate CLI, dsh.plugin.json engines floor, and the
@deepseek-ai/* peer floor / devDependencies baseline move to
0.1.2-alpha.5 (dsh-client-locale trails at 0.1.2-alpha.3 — no such
release upstream; ^0.1.2-alpha.3 already accepts the alpha.5 runtime)
- code: migrate the alpha.4 Session.events removal to snapshotEvents()
(sidechat transcript live reads, fork inheritance, jobs.output replay,
subagent activity) and drop the seedLength meta field the host removed
from CreateAgentOptions.meta
- gates: pnpm peers check clean, typecheck + 1137 unit tests green,
real-host mount smoke 14/14 on npm-published 0.1.2-alpha.5
The comparison table (3-run medians on the same machine against a real
0.1.2-alpha.2 host): mount latency 377→273ms (-28%), the host's
aggregated client bundle ships 203KB less over the wire (-14%,
matching the 19 dictionaries' gzip weight) and 640KB less decoded
(their source weight), boot settings.get 4→2, the bottom-drag width
leak 504px→0. Frame pacing was already at 8/10ms p50/p95 — the drag
fix removed the host-layout snap, not a frame drop. Structural wins
that don't show in a single sweep (git spawns per poll tick, fold
passes per poll, transcript row re-renders, per-keystroke doc
stringification) are listed with their per-event arithmetic.
The bottom-push rule anchored on #root :has(> [data-slot=conversation]):
a :has() match cache invalidates on every #root subtree mutation, and
the streaming chat mutates that subtree constantly — every layout-push
frame (the bottom drag writes --dsh-sidebar-height per frame) paid a
whole-document selector re-evaluation. The shell's locator (which
already holds the measured column node for the ResizeObserver) now
tags it with [data-dsh-center-col]; the rule evaluates once per node.
The tag retargets with the ref on boot swap / HMR node replacement and
is removed on unmount; the drag lane pins exactly-one-tagged-node and
its identity as the conversation slot wrapper's parent. The dead
[data-pane] branch (renamed away in alpha hosts) is gone.
TextEditor: the CodeMirror updateListener re-stringified the WHOLE
document into React state on every keystroke (O(docLength) per key,
re-rendering the shell per key). The listener now only flips the dirty
flag; the preview's draft is snapshotted from the live view when
entering preview (or on a content swap), and save() already reads the
live document.
DSH itself is still on its 0.1.2-alpha line (npm `alpha` dist-tag), so the
plugin mirrors it: v0.18.0-alpha.0 publishes under the npm `alpha`
dist-tag and supports DSH 0.1.2-alpha.x only. Stable-DSH (0.1.0-rc.8 ~
0.1.1-rc.2) users stay on v0.17.1 (npm `latest`). Verified end-to-end
against a real 0.1.2-alpha.2 host: full vitest suite, typecheck,
build/pack, consumer type surface, and the headless mount smoke 14/14
(the prerelease version also passes `dsh plugin add file:`).
- peer floor raised `^0.1.0-rc.8` -> `^0.1.2-alpha.2` (the mount install
no longer warns: the old floor could not semver-match a prerelease
host); dsh.plugin.json engines.dsh `>=0.1.2-alpha.2`.
- Dropped the pre-alpha compatibility layer:
- e2e host RPC collapsed from the dot/slash dual dialect to slash-only
(rpcAttempt; the 404-probe negotiation and its cache are gone), and
parseLaunchUrl now requires the ?token= launch URL;
- MarkdownText labels collapsed to the nested single shape (the cast
became unnecessary against the alpha.2 declarations);
- the defunct `@deepseek-ai/dsh-client-runtime` row is gone from the
chunk externals allowlist (chunk-loader / tsdown / two specs) and
from dsh.client.inject.
- market-manifest guard now allows an exact prerelease version (alpha
cuts are not the market's verified `latest` target); release.yml picks
the npm dist-tag from the version (prerelease -> `alpha`, else
`latest`) so an alpha can never hijack `latest`.
- Docs retargeted: AGENTS.md §2/§3, README/README_EN badges + v0.18.0
-alpha.0 section + install note (`dsh-better-sidebar@alpha`), guide.
DSH 0.1.2-alpha.2 is on npm under the `alpha` dist-tag, so the CI mount
pin and the @deepseek-ai/* devDependencies baseline move up from
0.1.1-rc.1/rc.2 (the dead dsh-client-runtime devDep goes away with
them). Verified end-to-end against a real 0.1.2-alpha.2 host: full
vitest suite (1106), typecheck, build/pack, consumer type surface, and
the headless mount smoke 14/14 — the token URL, slash RPC and
MarkdownText labels contracts are unchanged from alpha.1.
- dsh-settings dropped the runtime `settingsNamespace` export:
namespaces are validated at compile time (SettingsNamespaceInput), so
the host passes the 'dsh-better-sidebar' constant directly and the
fake settings service in smoke.spec casts to the branded type.
- dsh-subagent bumped SUBAGENT_DESCRIPTOR_VERSION 2 -> 3: the version is
stamped by the host package; the sidechat seed assertion now follows
the constant instead of pinning a literal.
- Restored SessionEvent.ignorable and the RemoteError wrapping were
verified to have no impact on this plugin.
- e2e scratch profiles (e2e-mount.sh / e2e-aggregate-mount.sh) add
'@deepseek-ai/*' to minimumReleaseAgeExclude (mirroring the repo
root): alpha releases are often <24h old when the lane runs, which
pnpm 11's default minimumReleaseAge would refuse to install.
- vitest excludes .worktrees/** — local task worktrees carried stale
code against the shared node_modules and broke on the devDeps bump.
- Version lockstep 0.17.2 (package.json, dsh.plugin.json,
SIDEBAR_SERVICE_VERSION, README/AGENTS/guide docs).
DSH 0.1.2-alpha.1 removed the client `ctx.connection.api` face (Remote
gateway migration), so every Side Chat transcript poll (`sessions.history`)
threw TypeError into the view's catch and was swallowed — the tab rendered
an empty transcript forever, silently (no console error, so the mount lane
never caught it). The successor APIs are not a drop-in either:
session/follow|page reject plain session addresses for origin:'subagent'
logs (agent-busy fence) and paging cannot read past the current cursor.
Move the transcript to the plugin's own wire — one transport for every
DSH generation:
- new `sidechat.events` route: live threads read the in-memory
`agent.session.events`; cold threads read `sessionPersistence.inspect`
(both seams exist since 0.1.0-rc.8; alpha.1's inspect returns the
expanded logical log, never the packed chunk-row encoding). The
inherited seed is cut host-side (`threadOwnLogEvents`), polls ride an
`afterSeq` delta, and the response is tail-capped at 8000 events (the
old client walk ceiling).
- SideChatView.fetchThread is single-path; collectOwnEvents (the client
walk) is gone, and so are the ctx.connection mirror and inject entry
(no consumer left).
- transcriptRows keeps re-cutting at session/end-seed as defense in
depth.
Verification:
- unit: sidechat.events route (seed cut, afterSeq delta + never
resurrecting the seed, cap, cold/live sources, 404/503/bad-request),
full suite 1104 passed; typecheck and build (purity gate) green.
- mount e2e vs a real dsh-v0.1.2-alpha.1 source build: 14/14, including
the Side Chat tab sweep polling sidechat.events (performance resource
assertion) and live + post-dispose (persisted) route reads.
- mount e2e vs PATH dsh 0.1.0-rc.8: 14/14 (no regression).
- New persisted built-in pref workspaceFence (default true) under the
files card's secondary settings modal; host reads it per request via
the settings seam (fenceEnabledOf — absent/malformed stays ON).
- ensureWorkspacePath/ensureWorkspaceWritePath gain a fence param:
disarmed skips the containment assert but keeps realpath resolution;
wired through fs.tree/fs.read/fs.write, the media + html routes, and
the upload path (writeWorkspaceUpload fence input).
- Editor load failures and file-tree level errors show the localized
reason plus a one-click global off (FenceErrorNotice) that flips the
pref, adopts it into the store, and auto-retries the failed operation
(reloadSeq / retryDir) — the raw wire text is never shown.
- GitView's two client-side pre-checks (hidden open action + no-op
defense) respect the pref; store threaded through TreePanel/FileTree.
- i18n: 4 new keys across all 21 dictionaries; tests: fence-off route
coverage, prefs parsing, schema default, editor toggles list;
docs: guide §8/§8.1 + plans/2026-08-29 design record.
Absorb the consumer-facing API reference previously duplicated in
AGENTS.md and refresh stale content to v0.17.1:
- TabDescriptor: full SettingRow shape (select/multi, v0.13.0+),
urlTarget, richer dedupeKey/available/createTab semantics
- built-in tab table: replace stale explorer-based list with current
editor/sidechat/pinned-terminal reality
- service: features list completed (urlTarget/settingSelect/
floatWindows), OpenTabSeed meta null/undefined semantics, openFile
path-derived-id caveat
- settings: full built-in prefs key list, select rows
- new sections: float windows (§11) and the token-driven skinning
contract (§12, moved from AGENTS.md §8)
- traps: aionui right-panel mutex, i18n/better-locale, lazy chunks
- minimal example: drop removed @deepseek-ai/dsh-client-runtime peer
- references: 9-viewer typo fixed, plugins catalog / fs-search /
markdown-html / agent-opens entries added
- fix duplicated §11 heading; sections now run §1-§15
New global Side card setting `agentOpenTools` (default off, 常规 group):
when enabled, one `sidebar_open` tool is injected into the model so it can
actively open a local file, a local folder (tree rooted there), or an
HTTP(S) page in the calling session's sidebar.
- host: AgentOpenRegistry + registerOpenTool (src/agent-opens.ts); the tool
classifies http(s) URLs / stat-driven file/folder paths, refuses other
schemes, resolves relative paths against the session cwd, and reports
target-tab-disabled instead of silently no-oping. Gated like
agentTerminalTools (register/drain on settings watch).
- delivery: /sidebar/ws/agent-opens push (consume-on-send queue, replay on
attach); the tool result reports `delivered` so queued opens for
non-active sessions are honest.
- client: Sidebar subscribes and routes pushes to editor (file), folder
window (meta.dir, tree rooted at the folder — EditorHost), or browser
(URL) tabs; settings row in 常规 + 20 locale dictionaries.
- tests: agent-opens registry/tool spec, smoke gating + WS route list,
prefs/plugin-shape defaults, editor-host folder window, side-card rows.
- docs: design doc, AGENTS.md key lists + reference, README feature bullets.
