* fix(frontend): restore resizing for the artifacts and sidecar panels
#3934 replaced the right panel's ResizablePanelGroup with a fixed CSS grid to
animate open/close, which removed the drag handle; #4187 then reintroduced a
resizable group for the browser panel only. The artifacts and sidecar panels
have had no way to resize since, while the browser divider still drags.
All three right panels now share one panel group, so there is no per-panel-kind
layout fork. Open/close goes through the side panel's collapse()/resize() so the
width still animates, and a dragged width survives closing and reopening.
Three library-specific constraints, each found by a failing test:
- the size transition is applied from the group as
[&>[data-panel]]:transition-[flex-grow], because <ResizablePanel className>
lands on an inner wrapper while the element the library sizes is its own
[data-panel] div;
- reopening uses resize(remembered) rather than expand(), which falls back to
minSize until the library has recorded a size, and the remembered width is
read before collapse() because the closing animation reports shrinking sizes;
- during the animation the content is held at its final width in cqw and
clipped, as the previous grid layout did — letting it reflow every frame makes
the message list re-run its scroll-to-bottom and re-wraps the sidecar
composer.
Fixes#4465
* fix(frontend): remove unreachable panel max size
* feat(frontend): pin recent chats
* fix(threads): address pin-chat review feedback
- Stop bumping updated_at on metadata-only PATCH (pin/unpin) via a new
update_metadata(touch=False) path so unpinning no longer jumps a chat
to the top of the updated_at-sorted recent list.
- Narrow patchThreadMetadata to a ThreadMetadataPatchResponse matching
the Gateway's actual response (no values/context).
- Namespace the pinned metadata key as deerflow_pinned for consistency
with deerflow_sidecar / deerflow_branch.
- Cover touch/touch=False behavior in repo + router tests; document the
e2e mock's updated_at preservation now mirrors production.
* style(frontend): format thread utils test
* fix(threads): make pinned ordering server-side
* test(frontend): keep infinite-scroll fixture order stable
* test(frontend): stabilize lark reconnect e2e
* docs: clarify thread pin metadata contract
* perf(frontend): coalesce streaming renders to a frame budget instead of per chunk
While a run streams, the merge/group/render pipeline consumed every SSE chunk
as its own React update (~60/s), re-rendering the whole thread tree per token.
Enable the SDK's same-tick batching (throttle: true) and publish the
render-facing messages snapshot at most once per 80 ms with a leading edge and
a trailing flush, keyed through a memoized merge so identities stay stable
between flushes. Lifecycle consumers (optimistic clearing, summarization
capture, usage baselines) keep reading the per-chunk array.
* perf(frontend): keep the transient bridge order array identity stable
mergeTransientHistoryBridgeOrder cloned unconditionally, so the render-time
call handed the coalesced merge memo a fresh array identity on every render
while the transient history bridge was open, re-running mergeMessages between
flushes. Clone lazily and return the input order when nothing is appended; the
merge only ever appends, so an unchanged length means unchanged content.
Consumers only read the returned order, so reusing the input is safe.
* perf(frontend): drive the render coalescer from a monotonic clock
The coalescing interval was measured with Date.now(). A backward wall-clock
step (NTP correction, sleep/wake) turns the elapsed term negative, so the
scheduled delay becomes interval + jump and the rendered snapshot stalls for
the length of the jump. Read performance.now() once per effect invocation
instead; the timer callback re-reads it because timers fire late and the next
interval must start from the real flush.
Seed the last-flush marker with -Infinity so the first update of a stream
still takes the leading edge under a page-load-relative clock.
* perf(frontend): reset the coalescer flush baseline when a stream ends
The leading-edge flush was scoped to the hook instance rather than to each
stream: a run starting within one interval of the previous one found a recent
flush baseline and deferred its first frame. Drop the baseline when leaving
the streaming state so every stream opens on the leading edge.
* perf(frontend): disarm the trailing flush when the leading edge wins
decideCoalesce checks the elapsed interval before the pending-timer flag, so
an update arriving past the interval takes the leading edge while a trailing
timer is still armed. Timers fire late under main-thread load -- exactly the
regime this coalescer targets -- so that timer then publishes a second time
and slips the flush baseline forward, breaking the at-most-one-flush-per-
interval property when it matters most.
Disarm the pending timer in the flush-now branch, and cover the previously
untested elapsed >= interval && hasPendingTimer quadrant.
* perf(frontend): stop syncing the render snapshot while idle
The snapshot is only read while streaming, so keeping it current on every
idle messages change costs one wasted render per history refetch or thread
navigation. Dropping that publish outright is not safe either: the leading
edge runs in a passive effect, but the render where isStreaming flips true
paints first and returns the snapshot, so a stale one would be painted --
after a thread switch, another thread's messages, since the chat page
deliberately avoids re-mounting on navigation.
Make the snapshot nullable, where null means no snapshot belongs to the
current stream, and return the live array while it is null. The idle branch
then writes state once per stream end instead of once per idle update, and
the stale-frame window does not exist rather than being short.

* fix(frontend): format browser view changes
* fix(browser): keep browser optional and isolate sidecar layout
* fix(browser): address PR review security and IME findings
- Nginx: add a browser-stream WebSocket location before the generic
/api/threads regex so Live upgrades instead of downgrading to HTTP
(both nginx.conf and nginx.local.conf).
- Ownership: require an existing owned thread for the WS stream and REST
navigate, and tear down the browser session on thread deletion so a
later caller cannot reuse a retained page/cookies by guessing the id.
- SSRF: enforce the URL policy at the browser request boundary via a
context-level route guard covering redirects, popups, iframes, and
subresources (skipped for CDP-attached Chrome).
- IME: skip key forwarding while a composition is active so confirming a
CJK candidate with Enter no longer submits the remote page form.
Adds regression tests for the request guard, session teardown on delete,
and the composing-Enter key decision.

* Revert "fix(frontend): smooth streaming in long tool threads"
This reverts commit f0462516eabe77f138d4027ea1c714fb226683cf.
* fix(browser): address review security and lifecycle findings
- Reject cross-origin WebSocket upgrades on the live browser stream
(Origin allow-list reuse of CORS/same-origin helpers) to close a
WS-CSRF hole, and fail closed when the ownership store is absent.
- Warn when a CDP-attached session runs with the SSRF request guard
off, and drop the unreachable CDP screencast teardown dead code.
- Read browser session launch config from a single canonical source
(browser_navigate) so it is deterministic regardless of call order.
- Bound per-thread Chromium accumulation with idle-timeout eviction
and an LRU max-sessions cap.
- Reset the Live reconnect counter on a successful open so the stream
can't permanently stall after the cumulative attempt cap.
* fix(frontend): reduce long tool thread render stalls
Reuse stable historical message groups during streaming, defer heavy Markdown and browser previews, and lazy-decode message images.
* fix(browser): keep live control responsive during continuous input
Why: Manual browser control felt laggy — a physical click ran the remote
Playwright click three times and each non-move input synchronously awaited a
JPEG screenshot, so events queued behind capture (queue wait up to ~237ms).
The first async attempt used a trailing-edge debounce, which froze the visible
page until a wheel/keyboard gesture stopped ("scroll finishes, then it jumps").
What:
- Frontend forwards one `click` per physical click instead of also emitting
`down`/`up`, so the remote page is not clicked twice per gesture.
- Backend detaches live-frame capture from input dispatch: non-move actions
start a rate-limited background refresh loop (leading frame + bounded cadence)
that keeps emitting frames while input continues and never blocks dispatch.
- Add regression tests: input dispatch no longer awaits the screenshot, rapid
inputs coalesce, and continuous input keeps refreshing before it stops.
Scenarios: Verified in the live Browser panel — a single click completes in
~57ms (was blocked behind a 171ms capture), and a 1.14s sustained wheel gesture
renders ~7 frames throughout the scroll instead of one frame after it ends.

* fix(frontend): harden artifact and markdown rendering
* fix(#4117): restore allow-scripts for scroll-restore, fix citation XSS bypass
willem-bd identified these issues:
1. [REGRESSION] sandbox removed allow-scripts which broke HTML artifact
scroll-restoration — the injected postMessage script could not run.
The prior config (allow-scripts allow-forms without allow-same-origin,
i.e. opaque origin) was already safe. Restored with corrected comment.
2. [XSS bypass] CitationLink rendered <a href={href}> directly before
isSafeHref ran, so prompt-injected [citation:x](javascript:...)
bypassed the safety check. Moved citation block after the guard.
Also:
- Added mailto: and tel: to SAFE_HREF_PROTOCOLS
- Kept anchor-only attributes off the <span> fallback (React DOM warning)
Note: the loadMessages re-throw originally in this commit was dropped
during the rebase — upstream #4065 rewrote useThreadHistory as a
TanStack useInfiniteQuery that already surfaces fetch failures.
* test(e2e): update sandbox assertion to match allow-scripts allow-forms
The artifact preview iframe's sandbox was restored to 'allow-scripts allow-forms'
for scroll-restoration. Update the E2E test to expect the corrected value.
* fix(#4117): address review — ArtifactLink XSS guard, urlOfArtifact sandbox e2e
- Apply the isSafeHref guard to ArtifactLink (artifact-link.tsx) so a
prompt-injected javascript:/data: href in a .md artifact preview cannot
reach a real anchor in the main document, matching the guard in
createMarkdownLinkComponent.
- Add an e2e asserting the urlOfArtifact iframe (non-code
browser-previewable files like PDF) keeps its empty sandbox.
Note: the loadMessages error-surfacing changes originally in this commit
were dropped during the rebase — upstream #4065 rewrote useThreadHistory
as a TanStack useInfiniteQuery whose queryFn already throws on
!response.ok and surfaces the failure via a toast.
* fix(frontend): let write_file non-code previewable artifacts render in sandboxed iframe
When a write_file artifact such as PDF is clicked in chat, the component receives a path that forced isCodeFile=true, hiding the sandboxed iframe behind the code editor. Now non-code browser-previewable files are detected early so the sandboxed iframe renders correctly.
Fixes the E2E test: renders sandboxed iframe for a browser-previewable non-code file.
* fix(#4117): align PDF artifact route pattern with convention (drop /mock/ prefix)
The test used /mock/api/threads/... for the PDF artifact content route,
but the urlOfArtifact helper generates /api/threads/... (without /mock/)
when isMock=false. The other tests (e.g. presented artifacts) already use
the correct /api/threads/... pattern.
* test(frontend): add render-level coverage for unsafe markdown/artifact links
- Render MarkdownLink and ArtifactLink via renderToStaticMarkup and
assert an unsafe javascript: href produces a disabled <span> (never an
<a>), including through the citation-labelled branch, and that safe
https hrefs render hardened anchors (target=_blank, rel=noopener).
- The new ArtifactLink render test caught the unsafe href leaking onto
the fallback <span> through the {...rest} spread; drop the spread in
both span fallbacks so anchor-only attributes (href/target/rel) and
react-markdown's node prop never reach the span.
- Cover mailto:/tel: in the isSafeHref unit cases and fix the stale
SAFE_HREF_PROTOCOLS docstring that still claimed http/https-only.
* fix(frontend): route the agent save-hint through the safe localStorage facade
Export safeLocalStorage from core/settings/local and use it for the
agent-create save-hint read/write so blocked browser storage (Safari
private mode, strict containers, embedded WebViews) cannot throw from
the effect. core/agents/feature-cache.ts already guards its
localStorage access with try/catch, so settings + agent pages are now
consistently best-effort.
* fix(frontend): allow scheme-less relative markdown links in isSafeHref
* fix(workspace-changes): classify a symlink replacing a file distinctly from deleted
scan_workspace_roots() skipped every symlinked path entirely
(host_file.is_symlink() -> continue), so the path was completely absent
from a snapshot instead of being recorded as a metadata-only stub the
way binary/large/sensitive-looking files already are. When an agent run
replaces a tracked file with a symlink (e.g. rm config.txt && ln -s
/some/other/path config.txt), the after-snapshot never contained that
path at all, so compare_snapshots()'s _status() saw after_file=None and
reported plain "deleted" -- silently hiding that the path is still alive
on disk, now as a symlink that can point anywhere on the host, including
outside the workspace root.
Add a "symlink" classification mirroring the existing binary/large/
sensitive pattern: scan_workspace_roots() now records a symlink as a
metadata-only FileSnapshot stub (symlink=True, symlink_target from
os.readlink(), lstat'd without ever following the link) instead of
omitting it. _status() reports "symlink_created" whenever a symlink
newly occupies a path that was not already a symlink (brand new or
replacing a prior file), so the security-relevant fact surfaces
distinctly instead of collapsing into "deleted". A symlink genuinely
removed with nothing replacing it is unchanged: still "deleted".
Verified against a real POSIX symlink (WSL; native Windows symlink
creation needs elevated privilege) driving the unmodified
scan_workspace_roots()/compare_snapshots() functions, and via a
patch-file revert/reapply cycle on this same fix to confirm the added
regression tests fail before and pass after.
* fix(workspace-changes): count symlink_created in the changed-file badge
getChangedFileCount summed only created + modified + deleted, so a run
whose only change was a symlink replacing a file (reported as the new
symlink_created status, not deleted) produced a count of 0 and
WorkspaceChangeBadge hid the badge entirely -- the exact scenario this
PR targets, with the opposite of the intended result.
Add symlink_created to the frontend WorkspaceChangeSummary interface
(already emitted by the backend) and include it in the count. The
per-file StatusIcon/statusLabel "modified" fallthrough is unaffected
and left as a follow-up, per review.
Regression test reverts cleanly to reproduce a count of 0 pre-fix.
* fix(workspace-changes): rank symlink_created in file sort and complete the type contract
sortWorkspaceChanges's statusRank had no entry for the new
symlink_created status, so statusRank[left.status] - statusRank[right.status]
evaluated to NaN for any comparison involving a symlink-created file,
violating Array#sort's ordering contract instead of producing a
deterministic order. The frontend WorkspaceChangeStatus and
DiffUnavailableReason unions, and the WorkspaceFileChange symlink
fields, also stayed narrower than what the backend now emits, so
TypeScript's satisfies Record<...> guard on statusRank could not catch
the gap.
Widen WorkspaceChangeStatus to include "symlink_created" and
DiffUnavailableReason to include "symlink", add the matching
symlink/symlink_target_before/symlink_target_after fields to
WorkspaceFileChange, and give symlink_created a rank alongside
modified in statusRank -- restoring the satisfies guard's ability to
catch a future unranked status. unavailableLabel now has an explicit
"symlink" branch (new symlinkUnavailable i18n string, en-US + zh-CN)
instead of falling through to the generic label.
Also fixes the failing e2e-tests CI check: the existing
workspace-changes.spec.ts mock summary predates the symlink_created
field, so getChangedFileCount computed 1 + 1 + 0 + undefined = NaN and
the badge rendered "Edited NaN files" instead of "Edited 2 files".
Added symlink_created: 0 to the mock to match the real backend
contract.
New sortWorkspaceChanges unit tests revert cleanly against the
unranked statusRank to reproduce the NaN-driven misordering. pnpm test
(626 tests), pnpm check, and pnpm format are clean, and the
previously-failing e2e spec plus the full e2e suite (94 tests) pass.

* feat(frontend): render slash-skill activations as inline chips
Show an explicit `/skill` activation as a compact inline chip in both the
composer and the chat transcript instead of raw slash text.
- Composer: selecting a skill suggestion stores it as a removable chip
aligned inline with the textarea; the leading `/skill ` prefix is
reattached only at submit time, so the backend activation protocol is
unchanged. Backspace on an empty input or the chip's close button clears
it; history navigation is disabled while a chip is active.
- Transcript: human messages that begin with `/skill` render the skill as a
read-only chip followed by the task text.
- Add a shared `core/skills/slash.ts` (`parseSlashSkillReference` +
`resolveSlashSkillDisplay`) mirroring the backend `slash.py` gate, so the
transcript only shows a chip when the skill actually exists and is enabled.
This removes a duplicated regex/reserved-name list and keeps display
semantics consistent with backend activation.
Add unit tests for the shared slash parser and extend the chat e2e to assert
the composer still submits `/skill <task>` after showing a chip.
* chore(frontend): format chat e2e test
* refactor(skills): address slash-skill chip review feedback
Follow-up to the inline slash-skill chip PR, resolving three second-order
review findings:
- Drive the reserved-command set and skill-name grammar from a shared
contracts/slash_skill_contract.json instead of a hand-copied
"keep in sync" pair. slash.ts and slash.py now reference the fixture, and
contract tests on both sides fail CI if either drifts.
- Extract a shared SlashSkillChip so the composer and transcript chips stay
in lockstep, and normalize the off-scale /8 and /12 opacity steps to the
standard /10 and /20 tokens.
- Split HumanMessageText into a pure parse gate plus a slash-only subtree
that owns the useSkills() lookup, so a skill-enabled toggle no longer
re-renders every plain-text human turn.
Verified: frontend eslint + tsc clean, pnpm test 572 pass (incl. new
slash-contract test); backend slash contract + slash-skills tests 31 pass.
* style(tests): sort slash skill contract imports
* fix(composer): inline the slash-skill text so the chip aligns with input
Address the "composer body layout change" review on #3981 by rendering the
active skill as an inline chip in the same text flow as the prompt, rather
than a separate flex row that drifted the box model across states.
- Render the chip + prompt inside one leading-6 wrapper and edit the prompt
through a `contentEditable` span, so the chip sits inline with the first
line and long/multi-line input wraps naturally back to the container edge.
- Align the chip with `align-top`: its h-6 (24px) height matches the text
line height, so chip and first-line centers coincide exactly (measured
delta 0), fixing the chip being raised above the baseline.
- Restore the placeholder in chip mode via a `data-empty` CSS `::before`,
which also gives the empty editable span width so it is no longer treated
as hidden.
- Widen the IME helper to `HTMLElement` and route the span's keydown/paste
through the shared skill-suggestion, prompt-history, backspace-to-clear,
and IME-composition handlers so contentEditable behaves like the textarea.
- Extend chat.spec.ts to drive the inline skill editor instead of the
textarea after a chip is shown.
* style(frontend): fix composer class order formatting
* fix(composer): break long unbroken input inside the slash-skill row
The inline slash-skill editor wrapped with `break-words`
(overflow-wrap: break-word), which only moves an over-long token to the
next line before breaking it. A long unbroken string therefore started
on the line below the chip, and when the string contained a break
opportunity such as a hyphen the browser wrapped there and pushed the
remaining run to the next line, leaving a wide gap on the right.
Switch to `break-all` (word-break: break-all) so the text fills each
line from the chip and packs tightly regardless of hyphens or CJK.
* feat: add composer input polishing
* Revert "Merge branch 'main' into feat/input-polish"
This reverts commit 5b6ceccf0db3092bc62fde3b05e7816829601756, reversing
changes made to 45fbc57fef5fa5fd878cf0176c37f3e3bc7ebef6.
* Merge main into feat/input-polish
* style(frontend): format input helper polish guard
* fix(input-polish): address composer polish review findings
Frontend
- Add a cancel affordance to the in-flight polish status pill that calls
abortInputPolishRequest(), so a slow/hung provider no longer hard-locks the
composer for up to stream_chunk_timeout with a page reload (and draft loss)
as the only escape.
- Reset promptHistoryIndexRef/promptHistoryDraftRef when a rewrite is applied
(and on undo), so a stale history-browse index can no longer let the next
ArrowDown silently overwrite the polished draft.
- Disable polishing while an open human-input card is present, matching the
frontend/AGENTS.md rule that composer entry points defer to the card so
card-reply metadata is preserved.
- canPolishInput now reuses parseGoalCommand/parseCompactCommand instead of a
third hardcoded reserved-command regex, and drops the phantom /help entry
(no /help parser exists in the composer), so future builtins only need to be
taught to the existing parsers.
Backend
- Extract the non-graph one-shot LLM path (build model + inject Langfuse
metadata + system/user invoke + text extract) into
deerflow.utils.oneshot_llm.run_oneshot_llm, shared by the input-polish and
suggestions routers so tracing-metadata and invocation shape cannot drift
between the two copies.
- strip_think_blocks gains truncate_unclosed (default True, preserving the
suggestions/goal JSON-prep behavior); input polish passes False so a draft
that legitimately contains a literal <think> substring is no longer
truncated into a partial rewrite or a spurious 503.
- Validate the empty-check and max_chars boundary against the same stripped
view of the draft that is sent to the model, so the user-facing length
boundary and the model input can no longer disagree.
Tests / docs
- Backend: literal-<think> preservation, whitespace-only rejection, and
normalized-length/model-input agreement cases; suggestions tests repoint the
create_chat_model patch to the shared helper module.
- Frontend: helper unit tests updated for the /help/reserved-command change; a
new Playwright case covers cancelling an in-flight polish request.
- backend/AGENTS.md documents the shared one-shot helper and the polish
normalization/think-tag behavior.

* fix(sidecar): make panel button delete the side chat instead of hiding it
The side chat panel's top-right button called `sidecar.close()`, which only
hid the panel — duplicating the header `SidecarTrigger` toggle. Repurpose the
button so the panel owns deletion and the header toggle owns hide/show.
- When a conversation exists, the button shows a trash icon and opens a
confirmation dialog before deleting via `useDeleteThread` (backend cascade).
- In the draft state (references only, no thread yet) the header trigger is not
rendered, so the button falls back to a plain close (X) that discards the
draft without a confirm — there is nothing persisted to delete.
Also fix a latent double-delete bug surfaced by the new dialog:
`useDeleteThread` deletes through the LangGraph route (which drops the
thread_meta row) and then calls `deleteLocalThreadData`, which hits the same
gateway handler whose `require_existing=True` guard now 404s. Treat that 404 as
idempotent success. The recent-chat delete used fire-and-forget `mutate`, so it
swallowed this error; the sidecar's `mutateAsync` surfaced it as a toast.
The e2e mock now mirrors the gateway ownership guard (second DELETE 404s once
the thread is gone) so the regression stays covered. Adds tests for delete,
draft-state close, and header-owned hide/show.
* fix(sidecar): lock delete dialog while deletion is in flight
The delete confirmation dialog disabled Cancel during an in-flight
delete but still allowed dismissal via the overlay, Esc, and the
built-in close (X). Those paths could imply the delete was cancelled
when it was actually still running. Ignore dismissals and drop the
close button while `isDeleting` so only the (disabled) Cancel path
controls the dialog.
* fix(sidecar): correct text-selection toolbar actions inside the side chat
The sidecar panel reuses MessageList, but it did not distinguish the side
chat surface from the main conversation, so selecting text inside the side
chat behaved as if it were the main list:
- The "Ask in side chat" action was shown even though the user is already
in the side chat, which is a no-op interaction.
- "Add to conversation" routed the snippet to the main composer's quotes
(conversationQuotes) instead of the side chat's own composer, so the
reference landed in the wrong input box.
Add a `sidecarSurface` prop to MessageList. On the sidecar surface, hide
"Ask in side chat" and route "Add to conversation" to `sidecar.openContext`
so the snippet attaches to the side chat's own composer (activeReferences).
Main-list behavior is unchanged.
* docs(sidecar): drop AGENTS.md note for the toolbar surface change
The sidecarSurface behavior is self-evident from the code; no dedicated
Interaction Ownership entry is needed.
* feat: add assistant turn branching
* fix(threads): skip workspace clone when branching from historical turn
Workspace files are not checkpointed, so cloning them onto a branch
rooted at an older assistant turn leaked files created in a later
timeline. Restrict the best-effort workspace copy to branches taken from
the latest turn; historical-turn branches now report
workspace_clone_mode="skipped_historical_turn" and keep only the
restored message history.
* style(frontend): fix prettier formatting in e2e mock-api
Collapse the branch-title normalization chain onto a single line to
satisfy the frontend lint (prettier --check) CI gate.

* feat: add workspace change review
* chore: format workspace change files
* fix: optimize workspace change summaries
* style: refine workspace change badge scale
* fix: restore workspace change user context import
* fix(frontend): gate workspace change badge to assistant messages
Only pass run_id to assistant MessageListItems so the workspace-change
badge can never render under a user's prompt, which carries the same
run_id. Assert single badge render in the E2E flow.
* fix(workspace-changes): address review feedback on diff parsing and badge
- Restrict unified-diff header detection to "+++ "/"--- " (trailing space)
in both backend _count_diff_lines and frontend getWorkspaceChangeLineClass
so content lines beginning with +++/--- are counted/styled correctly
- Gate WorkspaceChangeBadge to ai messages so tool messages folded into an
assistant group don't render a duplicate badge
- Add regression tests for both diff-classification fixes
- Apply prettier formatting to workspace-changes files flagged by CI

* feat(frontend): add side conversations for quoted follow-ups
* style(frontend): apply prettier formatting to sidecar-chat files
* fix(frontend): surface sidecar cascade cleanup failures via console.warn
Previously deleteSidecarThreadsForParent silently swallowed both
lookup errors and per-thread deletion failures, so parent thread
deletions could succeed while orphaning sidecar threads with no
signal to the caller. Log a warning that includes the parent id
and the failed thread ids/reasons so the leak is discoverable in
telemetry, matching the existing console.warn/error pattern in
this file.
* fix(frontend): address all sidecar review feedback
Resolve every reviewer comment on PR #3934:
- input-box/hooks/sidecar-panel: clear quoted references only via an
`onSent` callback that fires after the in-flight guard, so a dropped
send no longer silently discards quotes (willem-bd #3550).
- message-list: flip the selection toolbar below the selection when it
would clip above the viewport (willem-bd #3551).
- reference-metadata/thread/input-box: keep referenced ids, roles, and
count arrays 1:1 parallel instead of deduping ids (willem-bd #3552).
- message-list: widen selection containment to the shared assistant-turn
container and hint when a selection crosses messages (willem-bd #3553).
- sidecar/api: coalesce concurrent sidecar creates for one parent behind
a single in-flight promise to prevent duplicates (willem-bd #3554).
- sidecar-trigger/context: force-restore on trigger click so a sidecar
deleted elsewhere self-heals instead of opening a dead thread
(willem-bd #3555).
- threads/hooks: surface sidecar cascade cleanup failures via
console.warn for both lookup and per-thread deletes (Copilot).
Add unit + e2e coverage for parallel metadata, atomic create, and
trigger self-healing.
* feat: add scheduled tasks MVP
* fix: harden scheduled task execution semantics
* feat(scheduled-tasks): preset-driven schedule form with timezone and live preview
Replace the raw cron input with a preset Select (hourly/daily/weekly/monthly/custom)
plus structured inputs (time picker, weekday toggles, day-of-month), datetime-local
for one-time tasks, a timezone selector defaulting to the browser timezone, and a
live human-readable preview. Reuses one ScheduledTaskScheduleInput for create and
edit; backend contract unchanged; zero new deps (pure Intl + DST-safe offset helpers).
* feat(scheduled-tasks): full-page i18n + recipe templates + E2E locale pin
Localize the rest of the scheduled-tasks page (filters, detail pane, actions,
edit form, run list, enum values) via t.scheduledTasks.* in en/zh. Add four
built-in recipe templates (GitHub Trending, news digest, issue triage, weekly
report) exposed as a chip row that pre-fills title + prompt + schedule. Pin
Playwright locale to en-US so E2E selectors stay stable against i18n. No backend
change, no new deps.
* fix(scheduled-tasks): idempotent 0003 migration, update head constants, future-date once test
Merge with main surfaced three CI failures:
- 0003_scheduled_tasks create_table collided with legacy test seeds that
build from full metadata; guard with inspector.has_table so the revision
no-ops when the table already exists (0004/0005 are already idempotent via
_helpers.py).
- persistence bootstrap concurrency/regression tests pinned HEAD to main's
0002_runs_token_usage; bump to the new head 0005_scheduled_task_thread_nullable.
- once-task router test used a fixed past run_at and tripped the
must-be-in-the-future validation; use a future date.
* address review: ok-check, 502 for trigger failure, mock fields, migration filename, doc fences
- fetchThreadScheduledTasks now checks response.ok like the other fetchers.
- trigger endpoint returns 502 (not 409) when dispatch fails outright, so
clients can distinguish a real conflict from a server-side failure.
- E2E mock normalizes scheduled-task objects with context_mode/last_thread_id
and nullable thread_id, matching the backend contract the UI renders against.
- Rename 0002_scheduled_tasks.py -> 0003_scheduled_tasks.py to match its
revision id (file was renamed in spirit already; filename now follows).
- CONFIGURATION.md: close the Tool Groups yaml fence and drop the stray fence
after the Scheduler notes so the sections render correctly.
* fix(scheduled-tasks): harden lease, poller, config, and frontend UX after review
* fix(scheduled-tasks): harden run lifecycle, overlap skip, non_interactive gating, and DST conversion after review
- defer a once task's terminal status to the run-completion hook; the task
stays running until the real outcome, and a startup sweep cancels once
tasks orphaned by a crash (launch-time 'completed' could stick forever)
- record interrupted runs as a distinct 'interrupted' run status with a
readable message; an interrupted once task ends 'cancelled', not 'failed'
- enforce overlap_policy=skip for fresh_thread_per_run via an active-run
pre-check (same-thread ConflictError can never fire across fresh threads)
- protect terminal run statuses from the late launch-path 'running' write
- honor context.non_interactive only for internally-authenticated callers;
arbitrary clients can no longer strip ask_clarification
- fix DST-stale timezone offset in zonedLocalToUtcIso by re-deriving the
offset at the resolved instant (once tasks fired an hour late around
spring-forward and the create->edit round-trip diverged)
- drop dead ScheduledTaskRunRepository.update_by_run_id; share one Gateway
API error helper between channels and scheduled-tasks frontends
* fix(scheduled-tasks): close review round-3 gaps in guards, concurrency, and API ergonomics
- scrub internal-only context keys (non_interactive) from the assembled run
config for non-internal callers: gating body.context alone left the same
key smuggle-able through the free-form body.config copied verbatim by
build_run_config
- guard update_after_launch with protect_terminal so the launch bookkeeping
write cannot clobber a once task already finalized by a fast-failing run's
completion hook (parent-row sibling of the run-row guard)
- reject a manual trigger while the task has an active run (409) instead of
launching a duplicate concurrent run on fresh_thread_per_run
- re-arm a terminal once task to enabled when PATCH pushes run_at into the
future; previously the endpoint returned 200 with a next_run_at that could
never be claimed
- make max_concurrent_runs a real global cap: each poll claims only into the
remaining budget of active (queued/running) scheduled runs
- paginate GET /scheduled-tasks/{id}/runs (limit<=200, offset) and push the
thread filter of /threads/{id}/scheduled-tasks into SQL
- stamp context.user_id on scheduler-launched runs, matching IM channels, so
user-scoped guardrail providers see the owning user

* implement goal continuations
* fix(goal): address review findings for goal continuations
- goal: key the no-progress breaker on a signature of the latest visible
assistant evidence instead of the evaluator's volatile free-text, so it
actually fires on stalled turns; thread the signature through every
worker persist / no-progress call site
- goal: align _stand_down_reason default caps with should_continue_goal
(8 / 2) so the two gate functions agree on goals missing the fields
- runtime: offload the synchronous checkpointer fallback via
asyncio.to_thread (goal.py + worker.py) to keep blocking IO off the loop
- frontend: i18n the GoalStatus "Goal" label (goalLabel in en/zh/types)
- frontend: extract pure composer helpers into input-box-helpers.ts with
unit tests (parseGoalCommand, readGoalResponseError, skill suggestions)
- tests: cover the evidence-based no-progress and default-cap behavior
- docs: align backend/AGENTS.md goal paragraph with actual behavior
- e2e: prettier-format chat.spec.ts (fixes the lint-frontend CI failure)

* feat(frontend): hide goal continuation counter until the agent continues
The goal status bar rendered a raw "0/8" before any auto-continuation, which
read as a mysterious score. Now the counter is hidden until
continuation_count > 0, then shows "Continuing N/M" with a tooltip explaining
the auto-continuation cap.
- Extract getGoalContinuationDisplay into a pure helper (hides at 0) + unit tests
- Add goalContinuing / goalContinuationTooltip i18n keys (en/zh/types)
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(goal): address review findings for goal continuations
Frontend correctness
- Fix the optimistic /goal result permanently shadowing server goal state:
the streamed continuation counter never surfaced for a goal set in-session.
Extract a shared useActiveGoal hook (used by both chat pages) that reconciles
the optimistic copy with server state via a goalReconciliationKey, de-duping
the copy-pasted goal block across the two pages.
- Stop /goal status|clear failures from escaping handleSubmit as unhandled
rejections (handleGoalCommand now returns success; the run only starts when a
goal was actually saved).
- Use a function replacer for the goal-status toast so an objective containing
$&/$1 isn't treated as a replacement pattern.
Backend cleanliness / correctness
- De-duplicate four byte-identical helpers (_call_checkpointer_method,
_message_type, _additional_kwargs, _is_visible_message) by importing them
from runtime.goal instead of re-defining them in the run worker.
- Remove the dead `checkpoint_tuple.tasks` durability guard (CheckpointTuple has
no tasks field) and document that pending_writes is the durability signal.
- Decompose the 176-line _prepare_goal_continuation_input: extract
_reread_goal_and_checkpoint and a _persist closure so the thread-unchanged
guard and stand-down persistence aren't open-coded three times. Document the
last-writer-wins write-window limitation as a follow-up.
- Add a shared parse_goal_command helper and use it from the TUI and IM-channel
/goal handlers (one place for the status/clear/set semantics).
Tests
- Restore the 11 command-registry tests dropped by the previous goal change
(filter_commands ranking/description, build_registry builtins/skills, resolve
cases) alongside the new goal tests.
- Add coverage for the IM-channel _handle_goal_command, the TUI _handle_goal
handler, parse_goal_command, and goalReconciliationKey.

* fix goal review feedback

* feat(sidebar): grey out Agents button with tooltip when agents_api disabled (#3757)
* fix(sidebar): show disabled Agents tooltip on hover, harden a11y + e2e (#3757)
- Wrap the disabled Agents button in a hoverable tooltip trigger so the
'feature not enabled' hint shows in the expanded sidebar, not only when
collapsed (the SidebarMenuButton tooltip prop is hidden unless collapsed).
- Add tabIndex={-1} and drop the redundant onClick preventDefault.

* test(agents): anchor e2e agents-API request filter with a path regex (#3757)
* fix(agents): don't expose backend config in disabled message; tell user to contact admin (#3757)
The disabled panel previously said 'Set agents_api.enabled: true in
config.yaml', leaking backend configuration to end users. Replace with a
generic 'not enabled on this server, contact your administrator' message
(matching the existing nameStepApiDisabledError copy). e2e now asserts the
contact-admin message and that no config.yaml/agents_api text is rendered.
* make format
* fix(agents): keep agents_api flag sticky during /api/features outage (#3757)
Failing open re-mounted the agents UI and re-triggered the 403 storm when
agents_api was genuinely disabled and /api/features was down. Persist the
last definitive answer and fall back to it (sticky) before failing open,
only failing open when nothing has ever been observed. Read the cached
value after mount so the first client render matches the server (no
hydration mismatch on the non-loading-gated sidebar).
* fix(sidebar): make disabled Agents entry keyboard/SR accessible (#3757)
The disabled-state explanation was hover-only: tabIndex={-1} removed the
entry from the tab order and the reason lived only in a pointer-triggered
tooltip. Keep it in the tab order and wire aria-describedby to a
visually-hidden reason so keyboard and screen-reader users learn why it is
disabled.

Closes#3192
Root cause
----------
The artifact preview header is driven by a Radix Select whose <SelectValue>
renders the label of the <SelectItem> matching the current value. The option
list was built solely from `artifacts` in ArtifactsContext, which is only
synced from `thread.values.artifacts` (chat-box.tsx). Artifacts surfaced via
the message-layer `present_files` tool call are never written back to
`thread.values.artifacts`, so when such a file is selected its filepath has
no matching <SelectItem>. Radix then renders an empty trigger and the header
filename appears blank, even though the preview body loads correctly.
Fix
---
Compute `artifactOptions` as a defensive union: if the currently selected
filepath is missing from `artifacts`, prepend it so a matching <SelectItem>
always exists. This keeps the header label in sync with the active file
without changing context semantics or coupling the UI to a future
auto-discovery mechanism (see existing TODO in chat-box.tsx).
Tests
-----
Add an e2e case that mocks a thread whose only artifact is delivered via
`present_files` (thread.values.artifacts = []) and asserts both the header
title and preview content render. All 21 e2e tests pass.
* fix(frontend): reset new chat on client-side navigation
Drive the chat reset effect with Next.js's reactive pathname instead of the render-time window.location-derived flag.
During App Router transitions, window.location may still point to the previous thread until commit, leaving chat state stale until another UI interaction triggers a render. Preserve the stale 'new' param guard so created thread UUIDs are not overwritten.
* test(frontend): add e2e to cover history-only new chat reset
* docs(frontend): clarify new chat pathname synchronization
* feat(suggest_agent): stop frontend from fetching when suggestions disabled
* wait for suggestions config to load before fetching

* fix(frontend): resolve stale subagent running state after stop
Subtask cards were recreated from task tool calls as in_progress whenever
the thread was loading. If a user stopped a run before the task tool returned
a ToolMessage, the card could remain running after reload, and could flip back
to running when a later user turn started streaming.
Derive pending subtask state from the current assistant turn instead of the
global thread loading flag. A task now stays in progress only while its own
turn is loading or while a matching ToolMessage exists for result parsing;
otherwise it is marked failed.
Add unit coverage for task ToolMessage matching and for the later-turn loading
regression.
* fix(frontend): refresh subagent card on terminal status transition
- notify React via a ref + post-render effect when a subtask flips to
completed/failed, so SubtaskCard updates without relying on an
unrelated MessageList re-render
- tighten the current-turn heuristic to `groupIndex === lastGroupIndex`
(precomputed once) — fixes the rare case where an earlier subagent
group in the same turn was kept in_progress, and drops the per-group
slice+some scan to O(1)
- rename `getPendingSubtaskStatus` → `derivePendingSubtaskStatus`
- narrow `toolCall.id` at MessageList call sites; skip task tool calls
without an id instead of `id!`
- add Playwright e2e covering reload-after-stop showing `Subtask failed`
* fix(frontend): render user messages as plain text and cap blockquote nesting
User messages are typed or pasted plain text, not authored Markdown, but
they were rendered through the full Streamdown pipeline. Pasted source
files got fragmented (indented chunks become code blocks, paragraphs
collapse and lose indentation), "$...$" spans were KaTeX-ified, and a
message with thousands of nested ">" markers overflowed the call stack
in marked's recursive blockquote lexer, permanently crashing the thread
on every load.
Render human message content verbatim with pre-wrap instead, and cap
blockquote nesting at 100 levels at the Streamdown chokepoint so model
output cannot trigger the same recursion either.
Closes#3500
* fix(frontend): absorb marked lexer crashes with a render fallback boundary
Review found two gaps in the nesting cap: marked's list and blockquote
tokenizers are mutually recursive, so a list marker in front of the
quote chain ("- > > > ...") bypassed the blockquote-only regex and
still overflowed the stack; and the line-based rewrite was fence-blind,
silently truncating literal ">" runs inside code blocks.
Add an error boundary around Streamdown that renders the raw content as
plain pre-wrap text when rendering throws (retrying on the next content
change), keep the cap as a fast path for the dominant pure-">" case,
and make it skip fenced and indented code lines.

Frontend connect flow:
- Open the runtime-config dialog only when a provider still needs
credentials; configured providers go straight to the connect flow, so
the binding-code/deep-link path is reachable from the UI again.
- After saving credentials, continue into the connect flow when a user
binding is still required (multi-user mode) instead of stopping at a
"Connected" toast.
- Extract shared provider-state helpers to core/channels/provider-state
and add unit + e2e coverage for the direct-connect and
configure-then-connect paths.
Provider status semantics:
- Report connection_status from the user's newest connection row;
with no binding it is not_connected, except in auth-disabled local
mode where a configured running channel is effectively connected.
Concurrency and event-loop correctness:
- Offload ChannelRuntimeConfigStore construction and writes, channel
service construction, and Slack connection replies to threads; add a
tests/blocking_io/ anchor for the runtime-config handlers.
- Consume binding codes with a conditional UPDATE so a code can only be
used once under concurrent workers; retry upsert_connection as an
update when a concurrent insert wins the unique constraint.
- Serialize ensure_channel_ready per channel so concurrent provider
polls cannot double-start a channel worker.
Config and migration hardening:
- Stop mutating the get_app_config()-cached Telegram provider config;
the runtime store now owns the UI-entered bot username.
- Register channel_connections in STARTUP_ONLY_FIELDS with the
standardized startup-only Field description.
- Match the legacy unsafe-id bucket by recomputing its exact SHA-1 name
so another user's same-prefix bucket can never be migrated.
- Remove the unused Telegram process_webhook_update path and document
src/core/channels in the frontend docs.

* Address PR review comments on authz scoping and channel runtime
Security (review feedback from ShenAC-SAC):
- Scope internal-token callers to the connection owner carried in
X-DeerFlow-Owner-User-Id instead of bypassing owner checks outright,
in both require_permission(owner_check=True) and the stateless run
endpoints. Internal callers keep access to their own and
shared/legacy threads, and may claim a default-owned channel thread
for its real owner, but a leaked internal token no longer grants
cross-user thread access.
- Require admin privileges for POST/DELETE /api/channels/{provider}/
runtime-config: runtime credentials and channel workers are
instance-wide shared state (same model as the MCP config API).
Read-only provider listing stays available to all users.
Performance (review feedback from willem-bd):
- Skip the redundant thread channel-metadata PATCH after the first
successful backfill per thread.
- Reuse the per-connection Slack WebClient until its token changes
instead of constructing one per outbound message.
- Reconcile channel readiness for all providers concurrently in
GET /api/channels/providers.
Also resolve the code-quality unused-import flag in the blocking-io
anchor by pre-importing the channel service via importlib.

* Reconcile UI runtime channel config with config reload on restart
Main now reloads a channel's config.yaml entry on restart_channel()
(#3514, issue #3497). Adapt the user-owned connection flow to coexist:
- configure_channel() restarts with reload_config=False — the caller
just supplied the authoritative config (browser-entered credentials
that are never written to config.yaml), so a file reload must not
clobber it with the stale on-disk entry.
- _load_channel_config() re-applies the UI runtime-store overlay used
at startup, so an operator-triggered restart keeps browser-entered
credentials for channels without a config.yaml entry and does not
resurrect a channel disconnected from the UI.
- Offload the reload's disk IO (config.yaml + runtime store) with
asyncio.to_thread, matching the blocking-IO policy on this branch.

* fix(frontend): paginate workspace chat list beyond 50 threads (#3482)
The sidebar 'Recent chats' and /workspace/chats list were hard-capped
at the first 50 threads returned by threads.search. Replace the
single-shot useThreads() consumers with useInfiniteThreads() and add
an IntersectionObserver sentinel to each list so further pages are
fetched on demand.
In search mode on the chats page, the sentinel is replaced by an
explicit 'Load more' button to prevent the observer from draining the
entire backend list while the filtered view stays empty.
- Add useInfiniteThreads + page-size constant and pure cache helpers
(map/filterInfiniteThreadsCache, getInfiniteThreadsNextPageParam)
- Mirror rename / delete / stream-finish updates into the new
infinite cache so optimistic UI stays consistent
- Extend the e2e mock to honour limit/offset slicing
- Unit tests for the cache helpers and pagination boundary
- Playwright e2e covering chats page + sidebar load-more, and the
search-mode guard against runaway auto-pagination
- Add en/zh i18n entries for the search-mode load-more button
Fixes#3482
* docs(frontend): clarify infinite-threads offset semantics and test post-delete invariant
- Add docstring to getInfiniteThreadsNextPageParam explaining that TanStack
Query freezes the returned offset into pageParams once, so optimistic cache
mutations that shrink page lengths (filterInfiniteThreadsCache on delete)
cannot retroactively move the offset backwards. Delete/rename paths
reconcile against the backend via invalidateQueries in onSettled.
- Add unit test covering the post-delete invariant.
- Fix misleading comment in thread-list-infinite-scroll.spec.ts: the
thread-search mock does not sort by updated_at; it returns the array in
the order provided.
Addresses Copilot CR comments on #3485.
* fix(frontend): mirror onCreated upsert into infinite cache; add sidebar Load-older button
Address review feedback on #3485:
- New upsertThreadInInfiniteCache helper; useThreadStream onCreated now
upserts into both the legacy ['threads','search'] cache and the new
infinite cache, so a freshly created thread appears in the sidebar
immediately during streaming instead of only after the run finishes
and onSettled invalidates the query. Restores parity with main.
- Sidebar Recent Chats now exposes a visible 'Load older chats' button
alongside the IntersectionObserver sentinel, so keyboard-only users
and environments where IO is unavailable can still reach older
conversations.
- Add zh-CN / en-US / types entry for chats.loadOlderChats.
- Cover the new helper with 3 unit tests (no-op on uninitialised cache,
prepend new thread to first page, merge with existing entry without
duplication).
