fix(frontend): restore user message above same-run steps after mid-run reload (#4660)
* fix(frontend): restore user message above same-run steps after mid-run reload

After a mid-run page reload, replayed messages-tuple steps can reach the
merged list before the turn's human message (the retained replay buffer
may have dropped it), and the live-only human is woven in before the next
shared history anchor. The steps panel then renders above the user
message it belongs to and the per-turn token row splits one run in two.

restoreLocalTurnMessageOrder only covers the locally submitted turn, so
add restoreReconnectedTurnMessageOrder for the reconnected path: a
visible AI/tool step above the last visible human is provably misplaced
when the same run also appears below the human (canonical history is
seq-sorted), or when the step is run_id-less (live-only) and a
run_id-less step follows the human. Pagination orphans from older turns
(#4399) and resent turns after an interrupted run fail both checks and
keep their position.

* fix(frontend): never move a completed turn's terminal answer below the next human

Branch-seeded threads and mocked feeds can share one run_id across turns,
so the same-run sandwich check alone misfired on completed multi-turn
history: a previous turn's final answer was pulled below the next user
message, stripping the turn of its branchable assistant group (e2e
branch-thread.spec.ts).

Only steps after the last terminal assistant answer (visible content, no
tool calls) in the segment are now candidates for reordering. A
still-streaming text step can look like a terminal answer until its tool
call arrives (#4304); it then stays above the human until canonical
history heals the order — an accepted transient, far safer than moving a
completed answer.

fix(frontend): keep inline-code <think> pairs in content and restore copy for reasoning-only turns (#4647)
Two related fixes in the reasoning extraction path of
core/messages/utils.ts:

1. splitInlineReasoning's first pass stripped every closed
   <think>...</think> pair unconditionally, so a message that discusses
   the tag literally in markdown inline code (e.g. "Wrap your reasoning
   in `<think>...</think>`") had its code span hollowed out and the
   inner text shipped to the Reasoning panel. The streaming pass already
   guards backtick-adjacent openers; apply the same guard to the
   closed-pair pass so both passes agree on what counts as literal tag
   talk.

2. getAssistantTurnCopyData fell back to reasoning via
   `content ?? reasoning`, but extractContentFromMessage never returns
   null, so the fallback was dead code and a reasoning-only turn (e.g.
   stopped mid-thinking) rendered no copy button at all - inconsistent
   with getMessageCopyData, which does copy reasoning in that case. Use
   the same empty-string check it uses.

feat(frontend): reopen the skill list after a skill is selected (#4639)
* feat(frontend): reopen the skill list after a skill is selected

Selecting a skill closed the composer's skill list for good: `/` no longer
reopened it, so a skill could not be looked up or swapped without deleting
the chip first.

The list now reopens from the editable text beside the chip, and picking an
entry swaps the chip rather than stacking a second activation, since the wire
format carries exactly one leading /skill. Builtin commands are withheld in
that state because they own the whole composer line, and Enter navigates the
list before submitting except while an IME is composing.

The trigger is unchanged: a slash still opens the list only at the start of
the input.

* fix(frontend): keep builtin names reserved in the reopened skill list

Withholding the builtin list from getMatchingSkillSuggestions in chip mode
also disabled the reserved-name filter it drives, so a custom skill named
after a builtin command became selectable there. Nothing rejects such a name
at install time, and submitting the resulting chip runs the command instead
of the skill.

Pass the builtin list as before and drop the builtin entries from the result
instead. The new regression covers both sides of the reservation, and the
reopen test now waits for the list before pressing Enter.

* fix(frontend): hide skills the slash parsers refuse from the picker

The composer picker reserved only the two builtin command names, while both
slash parsers refuse the seven names in the shared contract. A skill named
bootstrap, help, memory, models, new or status was therefore offered, could
be selected into a chip, and submitted — and then activated nothing, because
parse_slash_skill_reference drops the name on the way in. The turn reached
the model as literal text with no skill loaded and no error anywhere.

Reserve the contract names alongside the builtin ones, so the picker cannot
offer what the parsers will not honour.

fix(frontend): hide stale follow-up chips while a turn is streaming (#3395) (#3396)
* fix(frontend): hide stale follow-up chips while a turn is streaming (#3395)

Follow-up suggestion chips are generated when a turn finishes streaming,
but `showFollowups` did not exclude the streaming state. If a user sent a
new message before the previous response finished, the old chips (and the
lone close button) stayed mounted and overlapped the To-dos panel and the
input box.

Gate `showFollowups` on `status !== "streaming"` so stale chips are never
shown while a response is in progress.

* fix(frontend): suppress follow-up suggestions for user-interrupted turns (#3395)

Gating showFollowups on status alone was not enough: stopping a streaming
turn (or sending a new message mid-stream, which also stops it) flips
status back to a non-streaming state and triggers the follow-up generation
effect on that streaming->ready transition, producing chips for a
half-finished, interrupted response.

Track user interruption with a ref set in the stop path, and have the
generation effect skip that transition (and clear/hide any pending chips),
so follow-ups are only generated for turns that finished on their own.

fix(frontend): stop matching <header> as <head> in HTML preview base injection (#4625)
appendHtmlPreviewBaseHref detected the head tag with /<head[^>]*>/i,
which also matches <header ...>. For a fragment with no <head> that
opens with <header> - a common shape in agent-generated report pages -
the <base> element was injected after the <header> opening tag instead
of being prepended, so relative assets appearing before that point
(e.g. a leading <img>) resolved without the base and failed to load in
the sandboxed iframe.

Use the word-boundary-safe /<head(?:\s[^>]*)?>/i that the sibling
appendHtmlPreviewScrollRestoration already uses, keeping the two
injectors consistent.

* feat(artifacts): inline editing for text artifacts in the panel

Add a PUT /api/threads/{id}/artifacts/{path} endpoint that atomically
replaces an existing UTF-8 text file under /mnt/user-data/outputs after
verifying its SHA-256 revision. Active runs conflict (409); binary,
symlink, oversized, and non-output paths are rejected.

Frontend: edit/save/discard buttons, draft state with conflict detection,
CodeEditor onChange/onSave, loader SHA-256 from ETag, i18n, beforeunload guard.

Backend: PUT endpoint with thread reservation, atomic temp-file replacement,
sandbox sync for non-mounted providers, rollback on failure, ETag on GET.

Tests: 8 backend + 1 blocking-IO + 3 frontend test files.

feat: show real-time context window usage (#3125) (#3183)
* feat: show real-time context window usage in chat UI (#3125)

Adds a `context_usage` block to `GET /api/threads/{id}/token-usage`
(token count from the live checkpoint, the thread model's
`context_window`, and a percentage), introduces a new
`ModelConfig.context_window` distinct from the per-call `max_tokens`
output cap, and surfaces the percentage in the chat header — inside
`TokenUsageIndicator` when token-usage tracking is on, or as a
standalone badge when it's off so context capacity stays visible
independent of cost tracking.

* feat: per-category breakdown for context window usage

Replace the single-number context_usage payload with a Claude-Code-style
breakdown — messages, system prompt, skills, system/MCP tools (active +
deferred), custom agents, memory injection, autocompact buffer, and free
space — and surface it in the chat UI with a segmented progress bar and
per-row table.

* docs(config): document context_window across model examples

Add `context_window` to every example model in config.example.yaml so the
new chat-UI "% context used" indicator works out of the box for whichever
example a user adopts. Each value is the published default at the time of
writing; users are pointed at the official model spec to verify. Bumps
config_version to 11 so `make config-upgrade` flags outdated user configs.

* style: ruff format (line-length 240)

* review: address Copilot bot comments on #3183

- token-usage-indicator: switch `{contextPercentage && (...)}` to an
  explicit `!= null` check. (The string `"0"` is actually truthy in JS so
  the original code wasn't buggy, but the explicit check is clearer.)
- context-usage-breakdown: drop the `useMemo` around segments/totals — the
  computation is O(n) over a handful of rows and the previous memo deps
  omitted `t.contextUsage.categories`, so the bar's tooltips/aria-labels
  could stay in the old language after a locale switch.
- context_usage._split_tools: snapshot MCP names from
  `get_cached_mcp_tools()` directly instead of re-reading
  `extensions_config.json` after `get_available_tools()` already loaded
  it. Removes redundant file I/O on every `/token-usage` poll.
  (`get_available_tools()` still emits its own INFO logs — silencing
  those is out of scope here.)

* style(frontend): prettier --write context-usage-breakdown

* fix(gateway): correct context-usage breakdown + add exact token counting

The context-usage indicator shipped two bugs that silently zeroed whole
breakdown rows (both caught by try/except, so the feature looked alive but
produced wrong numbers):

1. _count_system_prompt passed app_config= to get_deferred_tools_prompt_section,
   which only accepts deferred_names -> TypeError swallowed -> system_prompt
   row always 0, and used_tokens/percentage undercounted by the full prompt.
   Also subtracted the deferred section twice (the rendered prompt already
   excluded it). Fix: derive deferred names deterministically and pass them to
   apply_prompt_template; drop the redundant subtraction.

2. _split_tools imported a non-existent get_deferred_registry -> ImportError
   swallowed -> all four tool-category rows always 0. Fix: classify via the
   public is_mcp_tool predicate + tool_search.enabled (mirrors
   build_deferred_tool_setup); the MCP tag is set by get_available_tools.

Added token_usage.counting (approximate|exact). 'exact' routes text/schema/
message counting through the model tokenizer (tiktoken cl100k_base) via the
existing memory-module machinery (lazy load + cache + cooldown + CJK-aware
fallback), so CJK-heavy threads stop being undercounted by chars//4.

Regression + e2e tests added; 6621 backend tests pass.

* fix(gateway): harden context usage accounting

* fix(gateway): count promoted MCP tools as active in context usage

Promoted tools (deferred MCP tools the thread has fetched via tool_search)
have their full schema bound on every subsequent turn by
DeferredToolFilterMiddleware, so they consume context like any active tool.
The breakdown previously left them in the reserved *_deferred rows, under-
counting the thread's used_tokens.

Classification now treats a tool as deferred only when tool_search is enabled,
it is MCP-sourced, AND it has not been promoted. The promoted set is read from
the checkpoint's channel_values and scoped by catalog hash — matching the
runtime middleware, so a stale promotion from MCP-config drift cannot inflate
the active count.

The static system prompt still lists all deferred tool names (promotions only
affect schema binding, not the prompt), so _count_system_prompt's deferred
rendering is intentionally left unchanged.

8 new tests cover classification, catalog-hash scoping (match / drift /
compute-failure / malformed), and checkpoint extraction.

* fix(context): address review feedback

* fix(context): count structured message payloads

* fix(context): harden usage accounting

* fix(config): bump schema for context usage fields

* refactor: narrow context usage to core indicator

fix(frontend): parse uploaded filenames containing parentheses (#4608)
parseUploadedFiles stopped the filename capture at the first "("
([^\n(]+), so an entry like "- photo (1).png (12.3 KB)" failed to
match and the file silently disappeared from the message's file chips.
Browsers produce such names for duplicate downloads, making this a
common real-world shape.

Anchor the size group on the "(<number> <unit>)" pair the backend
emits (uploads_middleware formats sizes as "%.1f KB"/"%.1f MB") and
let the filename match greedily up to it, so parenthesized filenames
parse correctly.

fix(frontend): keep streaming reasoning above the answer text (#4578)
A reasoning model's turn showed its thinking below its answer while
streaming, then flipped to thinking-above-answer once the turn settled.
One message is rendered by two components with opposite ordering rules:
while streaming, an AI message with content and reasoning but no tool
calls yet is deliberately held out of the terminal bubble (#4304) and
rendered by MessageGroup's chain-of-thought panel, which pinned the
trailing reasoning disclosure to the bottom; the settled bubble paints
its <Reasoning> disclosure above the content.

Render the trailing reasoning disclosure before the assistant text that
follows it, and emit a message's reasoning step before its content step
in convertToSteps -- the step list was content-first, so ordering by
step position alone could not fix it. Assistant text emitted before that
reasoning keeps its earlier position.

This also covers two cases the report does not mention: tool-using turns
reversed the same way, and expanding "N more steps" showed a message's
answer above its own thinking.

fix(frontend): render one workspace-change card per run (#4559)
* fix(frontend): render one workspace-change card per run

The workspace-change card is resolved from (threadId, runId) alone, so
every AI message in a run fetches the identical summary. It was rendered
per AI message.

getMessageGroups() opens a separate terminal assistant group for every AI
message that has content and no tool calls, so a run ends in more than one
bubble whenever the model emits answer text mid-run that never gains a
tool call. Each bubble then painted a byte-identical "Edited N files"
card.

Fold the card onto a single position per run, matching how run duration
already anchors its own run-scoped display after the run's last visible
group. Anchoring keys on group index rather than message id because a
terminal assistant group holds exactly one message whose id may be absent.

Fixes #4555

* docs(frontend): explain the workspace-change anchor's group-type restriction

The helper narrows anchor candidates to terminal assistant groups while
getRunDurationDisplaysByGroupIndex accepts a run's last group of any type.
That asymmetry is load-bearing: run duration is emitted by MessageList
around every group, but the workspace-change card comes from
MessageListItem, which MessageList invokes only for human/assistant
groups. Anchoring a run that ends in an assistant:processing group would
pick a position that never renders and silently drop the card.

Record the rule in both places that could invite a future "unification":
the helper's docstring, and the frontend AGENTS.md paragraph that tells
maintainers where run-scoped displays belong.

fix(frontend): sync panel state when a drag collapses the side panel (#4556)
The shared right panel is collapsible with collapsedSize="0%", so dragging
the divider past minSize makes the library collapse it to zero without
going through the state that owns the panel. The panel disappears while
that state still reads open, leaving the divider draggable but inert and
the panel's trigger needing two clicks to bring it back.

Mirror a zero-width resize back into the owning state so a drag-collapse
closes the panel the same way its trigger does, and keep recording
non-zero widths there as the size to reopen at.

feat(lark): sidecar credential broker for sandbox lark-cli (Pattern B) (#4501)
* feat(lark): sidecar credential broker for sandbox lark-cli (Pattern B)

Removes the plaintext Lark credential mounts (appSecret + OAuth tokens)
from the sandbox container. A long-running broker sidecar owns lark-cli
and the per-user config/data dirs and serves the command surface over
Pod loopback; the sandbox gets only a forwarding shim on PATH, so the
raw credential files never exist in the sandbox filesystem.

- lark_broker.py: stdlib-only loopback broker (argv passthrough with
  shell=False, server-injected credential env, bounded I/O) + shim
  script constant + install-shim mode.
- docker/lark-cli-broker: init(install-shim) + serve image.
- provisioner: LARK_CLI_BROKER_IMAGE + provision_lark_cli_broker →
  shim init container + lark-cli-broker sidecar (config/data mounted
  sidecar-only); credentials dropped from the sandbox container;
  /api/capabilities reports lark_cli_broker_image. Broker supersedes
  the Pattern A init-container binary when both are configured.
- gateway: lark_cli_env_overlay(broker=True) omits config/data env;
  sandbox_lark_broker_active() TTL-cached mode resolver; broker added
  to sandbox_runtime_mode / readiness and the settings UI.

Opt-in and off by default (empty LARK_CLI_BROKER_IMAGE ⇒ no change).

Closes #4338

* fix(lark): address Pattern B broker review findings (#4501)

Follow-up to the sidecar credential broker addressing the PR #4501 review:

- shim: split the on-PATH lark-cli into a /bin/sh launcher + Python shim body
  so broker mode fails loudly (exit 127, actionable message) instead of ENOEXEC
  when the sandbox image ships no python3; interpreter pinnable via
  DEERFLOW_LARK_BROKER_PYTHON. Launcher bakes in the shim's absolute path since
  $0 is the bare command name when run off PATH.
- broker: drop the dead cwd payload field (broker can't see the sandbox FS) and
  document the command-surface-only / no-file-IO limitation.
- broker: return a structured 500 JSON on unexpected exec errors so the shim
  gets a meaningful message, not an opaque transport failure; set a handler
  socket timeout to bound slow/stuck connections.
- broker: add an opt-in DEERFLOW_LARK_BROKER_DENY_SUBCOMMANDS denylist that
  refuses secret-dumping subcommands before spawning the binary, forwarded from
  the provisioner sidecar.
- gateway: tighten the per-bash-call broker probe timeout (1.5s) and cache
  negatives longer (300s) so non-broker remote-provisioner users don't pay a
  latency hit; guard the mode cache with a lock; drop the dead
  _probe_provisioner_lark_cli_init_image wrapper.
- docs: remove the broken design-doc link from the broker README.

Adds tests for launcher python resolution, cwd omission, denylist enforcement,
500-on-error, hot-path probe timeout + negative caching, and provisioner
denylist-env wiring.

fix(gateway): replay edit and rerun from a settled checkpoint (#4534)
Editing the only turn of a thread reran the original prompt: the model
answered the question the edit was replacing while the UI showed the
edited text, and the edit vanished on reload.

The replay-base lookup decided whether a checkpoint predates the target
user message by message id alone. DynamicContextMiddleware re-keys the
first user turn to `{id}__user` mid-run, so every checkpoint written
before it holds the same prompt under an id the lookup cannot match. The
scan walked past those and anchored inside the run that produced the
turn — a checkpoint that still contains the original prompt and owns the
injection node's pending writes, which the replay then re-added after the
edited message.

Require the replay base to be a settled checkpoint (no pending tasks) in
both the lineage walk and the chronological fallback. That rule is
middleware agnostic: the first turn now anchors on the thread's empty
initial checkpoint and later turns on the previous run's tail, which also
drops the existing reliance on LangGraph discarding a stale `__start__`
write.

Edit replay additionally passes `head_checkpoint` so it resolves its base
lineage-first like regenerate does, and a replayed user message is
restored to its pre-swap id: replaying `{id}__user` into a state that has
no reminder yet makes the middleware treat the turn as already injected
and silently drops its date and memory block.

Frontend: a prepared replay masks the turn it supersedes, so the
optimistic-message baseline is taken from the post-mask human count. The
pre-mask count can never be exceeded when the replay puts exactly one
human message back, and on the first turn the runtime re-keys the
replacement message so identity comparison cannot stand in for the count.

feat(clarification): structured form fields for human-input cards (#4400 Phase 1) (#4406)
* feat(clarification): structured form fields for human-input cards

Add a request-side v2 `form` mode to the ask_clarification protocol so
business flows (e.g. expense reimbursement) can collect several values
in one card instead of sequential free-text questions:

- `ask_clarification` gains a restricted `fields` parameter (text /
  textarea / number / select / multi_select / checkbox / date)
- ClarificationMiddleware validates and normalizes fields explicitly
  (whitelisted types, unknown -> text, select-likes without options ->
  text, duplicate/invalid entries dropped, all-invalid falls back to
  the legacy modes) since the middleware short-circuits before tool
  execution; the plain-text fallback lists fields for IM channels
- Form payloads carry `version: 2` so older frontends degrade to the
  text fallback; replies stay on the v1 response protocol — the card
  submits a readable summary as `response_kind: "text"`, so journal
  persistence and answered-card recovery are unchanged
- Frontend renders typed field controls with required-field validation
  and compact multi-select chips

Part of #4400 (scope narrowed per maintainer feedback: request-side
only, no new response kinds, no top-level multi_choice).

* fix(clarification): harden form protocol per review feedback

Address the five review points on #4406:

- Reject field names colliding with JS Object.prototype members on both
  sides; frontend reads form values via own-property access only, so
  `constructor`/`toString`-style names can no longer leak inherited
  members into required validation or the submitted summary
- Close open requests answered through the legacy text fallback: a
  visible plain human reply (no response metadata) now marks every
  previously-opened request as answered, so upgrading to a v2-aware
  frontend cannot leave the composer locked on an already-answered card
- Give checkbox fields deterministic boolean semantics: values are
  seeded to an explicit false ("no" in the summary) and `required` means
  must-agree/consent; documented in the tool schema
- Make middleware field validation atomic: structurally broken entries
  (bad/duplicate/reserved names, over-cap field/option counts or text
  lengths) degrade the whole form instead of silently dropping fields;
  options are trimmed/deduped with blanks removed so the backend never
  emits payloads the frontend parser rejects
- Associate form labels/controls (htmlFor/id), aria-required,
  aria-invalid, and error descriptions for accessibility

* refactor(clarification): type the fields item schema via TypedDict

Replace `fields: list[dict[str, Any]]` with `list[ClarificationFormField]`
(a TypedDict with `name` required and the type whitelist as a Literal) so
the provider-facing tool schema documents the item shape instead of an
opaque object relying on the docstring. Runtime validation is unchanged
and stays in ClarificationMiddleware, which intercepts the call before
tool execution. Addresses the non-blocking review suggestion on #4406.

* fix(frontend): drop unsupported aria-invalid from multi-select group

jsx-a11y: role=group does not support aria-invalid; the error linkage

* fix(clarification): coerce numeric required flags and normalize fields once

- `_normalize_bool` now coerces 1/0 (some providers serialize booleans
  as integers), so `required: 1` no longer silently flips to optional
- `_handle_clarification` normalizes `fields` once and passes the result
  to both the text fallback and the payload builder

Addresses the non-blocking review nits on #4406.

* fix(clarification): harden form protocol per contract review round 2

Backend:
- Guard unhashable JSON in the intercept path: `type: []`/`{}` degrades
  the field to text and `clarification_type: []` coerces to str instead
  of raising TypeError (which, with return_direct, ended the turn with
  an error and no card or fallback)
- Add a total budget over the serialized normalized fields (16KB UTF-8
  bytes): per-item caps alone admitted forms whose IM text fallback
  exceeded channel delivery limits (Slack 40k chars, Feishu ~30KB card),
  silently truncating trailing fields; a boundary test proves any
  accepted form's fallback stays deliverable

Frontend:
- Submission value now appends a JSON block keyed by stable field names
  (readable summary alone is delimiter-ambiguous), with a collision
  regression test
- Parser boundary tightened to match backend constraints: empty option
  values (Radix SelectItem crash), duplicate option ids/values,
  duplicate field names, and the form<->version-2 binding are rejected
- Keep the error node mounted while any field is still invalid so
  aria-describedby never points at a removed element (happy-dom
  interaction test)
- Required semantics are now accessible: native checkbox control (no
  HTML required attribute — it would intercept the custom submit path),
  visually-hidden localized "required" markers next to the aria-hidden
  asterisks
- Legacy-fallback closure narrowed to the latest unanswered request:
  nothing guarantees a single outstanding clarification across runs, and
  closing all would silently swallow older decisions; an older request
  left open becomes the active card again

fix(frontend): allow dev-server access from non-localhost hosts (#4471)
Opening the dev stack on a LAN address or a proxied hostname serves the
SSR HTML but never hydrates: Next.js answers /_next/*, /__nextjs_font/*,
and HMR with 403 for any host it was not started on. The page renders, so
it looks up — but no client handler is attached, and the login form's
onSubmit never fires. It reads as "login is broken" rather than as an
asset problem, and the only clue is a warning in the dev-server log.

Wire Next's allowedDevOrigins to a new DEER_FLOW_DEV_ALLOWED_ORIGINS env
var. Unset by default, so the localhost-only default is unchanged; it is
also dev-only, as Next ignores allowedDevOrigins in production builds.

Entries are reduced to the bare host that allowedDevOrigins matches
against, since an entry pasted from the address bar as
"http://192.168.1.10:2026" would otherwise match nothing and leave the
operator with the same 403 they were trying to fix.

Reported in #54 and #203.

fix(frontend): restore resizing for the artifacts and sidecar panels (#4469)
* 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.
