An omitted `todos` on a tail request was treated as "no projection carried"
and preserved the prior value. Every installWindow caller is a tail request
(doOpen, its gap re-pull, repairGap; loadOlder prepends without it), which the
host answers with the full-log projection or omits only when the log holds no
todo/write — so the field's absence is the authoritative empty list. A live
write whose host crashed before persisting therefore left the rolled-back plan
on screen indefinitely; the assignment now clears it on the next open or
resync. Widened the parameter to an explicit `| undefined` so the two meanings
cannot be conflated again, and updated the JSDoc at both declaring seams plus
the bilingual README/note pair.
The session/queued frame no longer carries steering — AgentMessage no longer
has the field. The client derives it from the same ordered turn boundaries the
host saw (a frame arriving while a turn is open joined the steering FIFO).
- Mount WorkspacesService.startInitialSelection in the runtime apply (the
one-shot baseline follower shipped in 98633b5aa without a caller): a
restored current session wins, an explicit clear stays cleared, a failed
connect retries on the next baseline projection.
- Cover the policy in client-apply and the assembled workspace-flow
snapshot; startup now lands in the recent Workspace's blank session, so
the draft-carry scenario starts from the hero directly.
- Bring docs along: startup-selection paragraphs in the session-scope RFC
note (both languages), bilingual README pairs for the four new client
packages, doc-graph regeneration with client-declared events exempt from
the dispatcher requirement (client dispatch sites are structurally
invisible to the host-side ts.Program), and pairing re-records.
eslint --fix autofixes plus manual repairs: max-len line splits
(fake-api handlers, notifier/slots JSDoc, spec signatures), charAt over
non-null-asserted indexing in slash detect/menu cores, Array.from for
code-point capping, typeof assertions for unbound-method in specs,
generic getByRole for the send-button cast, effect disposer void-wrap in
command register, and dropped unused type imports.
Conflict resolution: session.ts keeps this branch's paired-start callTime
(the start event exists here; a settle-only window stays null — the PR2
fix's semantics compose). The README's codeDispatches section is restored
to the running→settled lifecycle this branch implements, keeping PR2's
null-callTime nuance for starts outside the window.
Responding to ds-review-bot round 2 on #653: the tool/code-dispatch event
is appended at settlement, so using its time as callTime fabricated a
zero-duration call for duration-aware consumers — it is now null (start
unknown) per the ToolResultNode contract, pinned in the session spec. The
README's codeDispatches section described the PR3 running→settled
lifecycle a stack ahead of this tree; it now documents the settled-only
index this PR ships (the running shape lands with the start event in
#658, which already merges cleanly over this).
Responding to ds-review-bot on #664 (root cause lives here): when a history
window carries a tool/code-dispatch settle without its paired start, the
runtime fabricated callTime = settle time, so downstream duration views
presented a measured 0 ms. Match the native tool-result contract instead —
callTime: null = unknown — and pin it; the trajectory cell already renders
null as the em dash, and the waterfall gains explicit unknown handling in
its own PR.
The bridge replaces its serialization queue with a pool that reuses the
native concurrency contract: submissions classify through
registry.executionMode (fail-closed isConcurrencySafe), start strictly in
submission order, overlap up to the validated maxParallelSubCalls config
(default 10; 1 restores serial), and exclusive calls drain the pool, run
alone, and bar later calls. Each started sub-call logs a
tool/code-dispatch-start event at pool entry; the existing
tool/code-dispatch settles the pair (started ⇔ settles exactly once;
abandoned queued calls log neither). SDK prompt guidance now states the
true Promise.all contract — re-recorded across every code/both-mode
snapshot (plus the stale cordis-dynamic-toolchain fixture gaining the
required description arg).
Client: CodeSubCall widens to RunningToolCall | ToolResultNode — starts
land the running shape (rows wear the native running ring), settles
replace in place preserving start order, callTime pairs to the start
time. Fixture emits start/settle pairs; jsdom pins the running sub-row;
runtime specs pin in-place settlement and out-of-order completion.
The client indexes tool/code-dispatch events into
ConversationSnapshot.codeDispatches (parent callId -> ToolResultNode-shaped
sub-calls; live mux and history replay build the identical index). ChatView
renders each run_code parent as the new code variant (description summary,
program as the expanded monospace body) with its sub-dispatches as
always-visible indented rows — every sub-row dispatches through the SAME
keyed conversation.chat.toolview hole with the same GenericToolCard
fallback, so custom registrations (bash sample) take over sub-rows exactly
as top-level rows. The details panel resolves sub-callIds to full logged
args and complete output through the native path.
Evidence: fixture turn 64 + built-bundle jsdom snapshot, real-machinery
jsdom suites (nesting, error state, details, running parent, reference
stability), and a recorded code-mode browser e2e round (keyless replay +
aria golden). Scaffold gains a toolsMode patch knob.
The hero composer renders the frontend Session Intent's retained prompt
from the sessions list snapshot, but updateIntent only reached that
snapshot through the intent watch's microtask-deferred markDirty. React
therefore rolled the controlled textarea back during the change tick,
which corrupted IME composition (Pinyin "nihao" committed fragments
like "nnini hni hani hao你好") and jumped the caret on plain typing.
SessionManager.updateIntent now calls notifyNow after
updatePendingPrompt, per the Notifier channel rule for direct echoes of
user gestures. The workspace-flow snapshot helper asserts the same-tick
echo instead of waiting for it, and a runtime unit test pins the
contract at the manager seam.
Sidebar session list grows the figma 239-10458 feature set and the
workspace/session browsing region moves wholesale into ui-workspace:
- Group-by menu (WorkSpace / In one list): flat mode lists every session
top-level, strictly newest-first; the choice persists across reloads.
- Session rows get a 500ms hover detail card (title / relative time /
status line) and a ... menu (Rename / Fork session / Delete session,
visual-only for now); workspace headers get ... with Rename (wired) and
Delete workspace (visual-only).
- workspace.rename RPC: trims, rejects duplicate titles on the create
chain (workspace-name-conflict), no-op on same title; modal dialog with
client-side duplicate pre-check.
- workspace.insertSessionBefore RPC (DOM-insertBefore semantics, omitted
anchor appends): HTML5 drag reorder of root sessions inside a workspace
group; order truth stays host-side, the view refreshes from the
response/changed frame.
- Activity pinning removed: the session/event touchSession chain is gone;
workspace accounts are manually owned (new sessions prepend, explicit
reordering only). Contracts and tests updated, api catalog regenerated.
- ui-sidebar reduced to the column shell (brand, fold state machine, New
Session, Settings) exposing one sidebar.workspaces hole with a two-fact
owner share {wide, expandSidebar}; ui-workspace owns the whole region
(header, search, grouped/flat lists, dialogs, drag) plus the picker via
a shared WorkspaceCreateFlow. The old sidebar.workspace picker slot and
its deferral indirection are gone.
- ui-primitives: Menu gains label entries, danger rows, and
closeOnPointerLeave; new HoverCard (portaled, open-delay, disabled
guard). Hover card and row menu never coexist.
repairGap installed the repulled window without the response projection;
a todo/write missed during the gap and already outside the new tail page
kept the stale list. The spec pins adoption through the repair path.
The client's todos projection derived only from the paged display window,
so reopening a session whose last todo/write preceded the tail page showed
an empty plan until the user paged back — session-level state cannot be
reconstructed from an arbitrary window. The host owns the full log, so the
tail history response now attaches todos (latest todo/write backscan, the
same posture as the view pairing); installWindow seeds it, window rebuilds
preserve it, and any in-window or live write keeps overwriting it. The
fixture mirrors the host; docs and both Agent Notes record the mechanism.
Session consumes the todo/write session event as a per-event side effect
(last write wins), rebuilds it on window replay/paging/resync, and exposes
snapshot.todos. TodoItem re-exported through the runtime surface.
- Added bilingual notes for the new session feature, detailing the transition to an empty state upon session creation.
- Updated `SessionsService` to include a `clear()` method that resets the current selection and persists the empty state.
- Enhanced the `EmptyState` component to reflect the new design, including workspace selection and input handling.
- Modified CSS styles for improved layout and visual consistency in the empty state.
- Updated tests to cover the new session clearing functionality and its effects on the UI.
The module system moves out of dsh-client-runtime (./loader retired) into
its own package: a lazy CJS table where executing a bundle only registers
its factory and materialization happens at first require, memoized, with
recursive requires self-ordering. ClientModuleSystem is a class; index.ts
keeps the types and a thin factory. Boot is two-phase: phase one prefetches
the immediately tier in parallel (registration only, failures deferred to
phase two's loud import); phase two mounts the vendored Loader with the
module system as internal, creates one entry per graph row plus the
app-shell pseudo-row the kernel appends itself, and settles on an
all-ACTIVE sweep. The shell kernel is self-sufficient: hand-rolled
loader-status stores, no plugin value imports, platform seed list single-
sourced in platform.ts.
Replace send/steer/inject with one Agent.send primitive over the
(target × wakeup) matrix; followup/steer/inject become fixed-preset
alias methods on the now-abstract Agent class. Coalesce context/message
into user/message (injected context is a non-user source). Replace
agent/queued with agent/inbox/enqueue/dequeue/discard, add cancel
keepInbox, and add a FIFO-conservation invariant.
Four rounds of structural rework on the conversation surface, converging
on one registration model for the whole client:
- Review fixes: open() leaves the inject factory (SessionsService owns
the semantic); ConversationService mounts via ctx.plugin(); the
bespoke view registry retires into the 'conversation.view' list slot.
- Ring alignment: createChatView factory retired (components get
everything through checkable shares at the register call site); the
hand-rolled t/i18n threading is deleted wholesale — a future
framework-level i18n will supply t as a standard prop keyed by slot
name, so no interim manual channel.
- Toolview dissolution: ToolViewRegistry / ToolViewResolver /
ToolViewOutlet / ctx.toolviews retire. Tool rows are entries of the
'conversation.chat.toolview' keyed slot (scope: session) declared by
the chat entry; ToolRowOwnerProps is the unified owner payload;
GenericToolCard becomes the call-site fallback; registrants are plain
plugins (inject ['slots','conversation'] as the load-order seam);
session-dimension dispatch moves into components (useSessions reads
parentId); trajectory/waterfall gain same-shape slots the day they
render tool rows (RendersCheck rejects empty declarations). Slot
names mirror the composition path (<domain>.<entry>.<hole>).
- Staging follows current: cell()/binding() are pure resolution
(render-safe); the constructor subscribes to the list store and
followCurrent opens the event window when the current session
changes — staging IS the open signal, business verbs are the timing,
React render/commit is decoupled from window lifecycle. A masked
current (projection gap) keeps the stage untouched so deferred
teardown semantics survive reconnects.
Agent Note: .agents/notes/implemented/architecture/
2026-07-23-toolview-dissolution.md (bilingual pair) records the
decision, the four rejected alternatives, and the accepted semantic
changes; the web client architecture note and packages/client/AGENTS.md
carry the current-state narrative.
Verified: typecheck 0, duplication 0 clones (478 files), full coverage
run 6190 passed with zero threshold errors, knip 0, doc-sync 24/24,
client aggregate tsc 0, render-count checks (one commit per chunk, zero
row re-renders under streaming) green.
The store migration (#538) parked the engine in a store/ sibling domain;
loader and sessions imported it directly, tripping verify-client-domain-graph
(cross-domain shared surface must route through contract/). The engine is
layer-0 shared infrastructure by definition, so it moves to contract/store.ts
verbatim; the four importers and the spec follow mechanically.
The data layer no longer depends on the React glue package, and business
plugins no longer depend on web-react at all:
- The store engine (zustand vanilla + immer + persist + dev freeze),
defineStore, and shallowEqual move to @deepseek-ai/dsh-client-runtime,
exported from the ./client main entry — no ./store subpath survives on
either package (the web-react one is deleted, none is opened on runtime).
- Store products are bare snapshot sources: useSelector leaves
SnapshotStore/StoreInstance and Session; every hook is composed at the
binding site in web-react's renderer (per-source cached uSES binding).
The SlotRendererHost sessions face carries bare observables only.
- SessionProvider becomes a standard-kit seat: an entry whose children
declare a session-scope slot receives the framework component as a prop,
retiring the last value import of web-react from plugin packages.
UseSession and the session-area types now live in ui-slots.
- web-react shrinks to the shell-only React glue (renderer, providers,
uSES bridge); zustand/immer belong to runtime alone; the module-table
seed and tsdown externals drop the web-react/store seat.
- NODE_ENV replacement is defined once in the shared tsdown client preset
(browser bundles inline the engine and lost vite's define); the 3-line
process.env typecheck shim moves to runtime with the engine.
- Stray tsc artifacts (.js/.d.ts/.d.ts.map beside sources under src/)
swept repo-wide; they shadow real sources under vitest resolution.
Verified: both aggregate typecheck programs at zero; 604 client tests
green; repo-wide grep for web-react/store at zero; real-host playwright
run 7/7 including persist round-trip.
ci: fix test/docs
The definitive slot model for the web client, replacing the first-generation
define/register two-step, ScopedSlots whitelist faces, and binding handles:
- 'root' is the only a-priori slot (SlotsService built-in); the shell renders
exactly ctx.slots.renderSlot('root', {}).
- register is the single API: children = slot declaration + render
authorization + runtime spec in one options object; misconfiguration fails
loud at load (duplicate declaration, undeclared contribution, one store
handle under two scopes).
- Component props arrive in four auto-derived shares: PropsRuntime<K>
(owner params + session/global standard kits via declare-merge),
PropsRenderSlots<S>, PropsStore<H>, and the inject business face.
sessionId is framework-supplied; hooks are framework-made only.
- Framework store seat: defineStore factories declare schema/actions/persist;
read = useStore, write = baked actions only; store scope derives from the
mounting entry; per-session persist keys and clearPersisted lifecycle.
- inject factories read the apply closure's own ctx (binding handles retired;
root-ctx back door closed); SessionProvider is self-wired render-prop.
- Rendering sits behind the SlotRenderer install seam; runtime stays
React-free; ownership ledger keyed to the single entry axis closes the
stale-authority window (StaleAuthorizationError probes).
Docs: the slot type-chain note is refreshed in place as the slot system
standard RFC (bilingual pair re-recorded); the web client architecture RFC
defers its slot sections there; packages/client/AGENTS.md gains the slot and
props discipline; gui-testing/web-styling notes drop missions/ references.
Tests: suites rewritten to the standard (props fed directly, real store
engines via createXXXStore().create(), no render machinery); load-time
negative samples for declaration/authorization/store conflicts; verified by
real-host playwright run (three columns, empty state, collapse, keyed session
remount, cross-slot selection sharing).
docs(ui-sidebar): point contract reference at the committed slot standard RFC
missions/ is workspace-local and never committed; the README must not cite it.
