fix(token-budget): acquire _lock in _apply, before_agent, and _drain_pending_warnings (#3714)
_lock was defined in __init__ and used only in reset(), leaving _apply(),
before_agent(), _clear_run_state(), and _drain_pending_warnings() unprotected.
Concurrent after_model callbacks for the same run_id could race on
usage_accum.input += diff_input, causing lost-update on token counters.

Also fix stray bare 'a' character in frontend/src/content/zh/introduction/index.mdx
that rendered as visible text on the documentation page.

fix(agents): skip dateless reminders in dynamic-context date scan (#3685)
* fix(agents): skip dateless reminders in dynamic-context date scan

_last_injected_date returned at the first message flagged
dynamic_context_reminder regardless of whether it carried a
<current_date>. Since #3630 split injected context into a date
SystemMessage plus a separate dateless <memory> HumanMessage, the
reverse scan hit the memory message first and returned None, making a
later turn look like the first turn. The middleware then re-injected,
re-targeted the previous turn's __user message via the ID swap, and left
the stale message as the latest human turn -- so the model re-answered
the previous message and the persisted message stream got scrambled.

Skip flagged reminders without a <current_date> so the scan reaches the
real date SystemMessage. Add a regression test for the 2nd-turn +
memory-enabled scenario.

Fixes #3684

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(agents): make injected reminder date authoritative via metadata

Promote the dynamic-context date out of message content into
additional_kwargs["reminder_date"] on the date SystemMessage.
_last_injected_date reads that key instead of regex-parsing content, with a
SystemMessage-scoped content fallback for checkpoints written before the key
existed.

This removes two structural fragilities raised in review of #3685:
- the boolean dynamic_context_reminder flag no longer has to also mean
  "carries a date" -- dateless reminders simply lack reminder_date and are
  skipped, so a future reminder type cannot reproduce the shadowing bug.
- the date regex no longer runs on the user-influenceable memory HumanMessage,
  so a memory fact containing a literal <current_date> cannot spoof the
  injected date (false same-day skip / false midnight crossing).

Add regression tests for memory date-spoofing, structured-date stamping, and
legacy (no-key) detection; update existing date-reminder fixtures to the
production shape.

perf(subagents): dedup streamed AI messages via a seen-id set (O(n^2) -> O(n)) (#3687)
_aexecute collects AI messages from agent.astream(stream_mode="values"),
which re-yields the full state every super-step. The duplicate check rescanned
the append-only ai_messages list on every chunk -- any(m["id"] == message_id) --
so a run with M messages did O(M^2) work, and M reaches max_turns=150 for the
general-purpose / deep-research subagent.

Track an id-keyed set alongside ai_messages: id-bearing messages become O(1)
set lookups, and the id-less full-dict-compare fallback is preserved. Behavior
is unchanged.

fix(config): coerce null object config sections to their defaults (#3573)
* fix(config): coerce null object config sections to their defaults

#3434 made commented-out list sections (models/tools/tool_groups) parse as []
instead of crashing, but the same scenario still crashes for object sections:
commenting out every key under e.g. memory: / summarization: / guardrails:
makes PyYAML parse the value as None, and AppConfig then raises "Input should
be a valid dictionary" for that section — breaking the documented
`cp config.example.yaml config.yaml` first-run flow.

Generalize the handling: a model_validator(mode="before") drops None-valued
sections so each field falls back to its default (list sections -> [], object
sections -> their default config). This subsumes the previous list-only
field_validator and the database special-case. Required sections without a
default (sandbox) still error when null.

Adds test_app_config_coerces_commented_out_object_sections; the existing
list-section regression test still passes.

* docs+test: address review on null-section coercion

- Correct the _drop_null_config_sections docstring: it does not subsume the
  database special-case; _apply_database_defaults still owns `database` and
  applies concrete defaults beyond null-coercion.
- Strengthen test_app_config_coerces_commented_out_object_sections to assert
  each null section falls back to its expected default config type, not just
  that it is non-None.
- Add test_app_config_null_required_section_still_errors covering the
  required-section (sandbox) "still errors when null" claim.

fix(security): add input sanitization middleware for prompt-injection defense (#3630) (#3662)
InputSanitizationMiddleware: escapes blocked XML tags in user messages (<system> -> &lt;system&gt;) — de-identify, don't reject (AWS PII-style). Wraps user input in plain-text boundary markers (--- BEGIN/END USER INPUT ---) per OWASP structured-prompt guidance. System-Context Confidentiality clause prevents LLM from revealing internal instructions. Boundary-marker layer hardened against delimiter injection (self-suppression + break-out). Multimodal content blocks preserved during sanitization.

Addresses review feedback from @fancyboi999 and @WillemJiang:

1. Boundary-marker injection: strict startswith+endswith idempotency, neutralize user-supplied BEGIN/END tokens, forged-idempotency bypass fixed

2. Multimodal data loss: _rebuild_content preserves interleaved non-text blocks

3. CI fixes: replay_provider strips boundary markers before hashing, middleware chain assertions updated

4. Lint: ruff format applied on Linux (slice spacing + f-string collapse)

Test: 71 input_sanitization + 1 replay_golden + 14 tool_error + 93 tool_output_budget = 179/179 passed

fix(persistence): offload sqlite dir creation off the lifespan event loop (#3574)
init_engine runs on the FastAPI lifespan event loop, but created the SQLite
data directory with a synchronous os.makedirs (a stat + mkdir syscall),
blocking startup. Dispatch it via asyncio.to_thread, mirroring the #1912 fix
for the checkpointer's ensure_sqlite_parent_dir.

Adds a Blockbuster-gated regression test in tests/blocking_io/ that drives the
real init_engine path with a not-yet-existing sqlite_dir; it trips
BlockingError if the makedirs regresses onto the event loop.

feat(guardrails): expose authenticated runtime context in GuardrailRequest (#3665)
* docs: guardrail runtime attribution spec

* docs: guardrail request attribution implementation plan

* feat(guardrails): add runtime user context and attribution fields to GuardrailRequest

Extend GuardrailRequest with optional runtime attribution fields so that
pluggable GuardrailProviders can access authenticated user context and
tool-call-level attribution:

- Gateway injects user_role, oauth_provider, oauth_id into runtime context
  alongside the existing user_id (server-authenticated only, client spoofing
  prevented)
- GuardrailRequest gains: user_id, user_role, oauth_provider, oauth_id,
  run_id, tool_call_id (all optional, backward compatible)
- GuardrailMiddleware reads these from ToolCallRequest.runtime.context
- thread_id now actually populated from context (was always None before)
- Tests: 15 new/expanded tests covering Gateway injection, runtime context
  reading, partial/missing fields, and client spoofing prevention
- Docs: new Runtime Attribution section in GUARDRAILS.md with provider
  example and YAML policy illustration

* fix(guardrails): propagate attribution to subagents

* fix(guardrails): complete subagent attribution propagation

feat(community): add GroundRoute web search + fetch engine (#3675)
* feat(groundroute): add GroundRoute community web_search + web_fetch tools

GroundRoute is a meta search layer over six engines (Serper, Brave, Exa,
Tavily, Firecrawl, Perplexity) with price-based routing and failover. This
adds a self-contained community engine module (httpx only, no new required
deps) mirroring community/brave + community/tavily:
- web_search: POST /v1/search, normalize to {title,url,snippet,source_engine}.
- web_fetch: fetch a URL via mode=page.
- unit tests covering normalization, auth, clamping, and graceful errors.

* fix(groundroute): define empty groundroute extra for clean install

The docs install line 'uv add deerflow-harness[groundroute]' (mirroring the
tavily/exa/firecrawl pattern) referenced an undefined extra, which uv accepts
but warns about. GroundRoute needs no extra packages (httpx is a core dep), so
declare an empty 'groundroute' extra in deerflow-harness optional-dependencies
so the documented command resolves without a warning.

* fix(groundroute): per-tool api key + honor caller max_results (review)

Address maintainer review on PR #3675:
- _get_api_key(tool_name): web_fetch now reads the web_fetch config block's key
  instead of always web_search, so a flow that pairs GroundRoute fetch with a
  different search engine authenticates correctly. Mirrors serper/exa/firecrawl.
- web_search honors a caller-supplied max_results (sentinel default None),
  falling back to the configured value only when omitted, so the documented
  parameter is no longer silently discarded.
- warn-once is now keyed per tool. Tests cover both fixes (web_fetch key,
  agent max_results honored).

chore: remove standalone LangGraph Server remnants from agent docs (#3304) (#3671)
Follow-up to #3301 / #3344. The Gateway-embedded runtime is the standard
topology — there is no standalone LangGraph service — but two stale
references slipped past the cleanup guard:

- .github/copilot-instructions.md still told contributors that `make dev`
  "Starts LangGraph (2024)" and wrote logs/langgraph.log.
- SandboxAuditMiddleware's docstring pointed audit logs at langgraph.log.

Update both to the Gateway-embedded reality (gateway.log) and extend
test_gateway_runtime_cleanup.py to pin the agent-instruction docs so the
standalone references can't reappear.

Stays within the safe scope of #3304: does not touch langgraph_auth.py,
langgraph.json, or the langgraph-api / langgraph-cli / langgraph-runtime-inmem
deps, which the issue gates on maintainer confirmation of Studio / direct
LangGraph Server support.

perf(sandbox): speed up should_ignore_name in glob/grep walks (#3657)
should_ignore_name runs once per directory entry during glob/grep tree
walks and looped over ~57 IGNORE_PATTERNS calling fnmatch per pattern.
Precompute the literal names into a frozenset (O(1)) and the few glob
patterns into one combined compiled regex via fnmatch.translate; per name
it's now one normcase + a set lookup + at most one regex match.
os.path.normcase preserves fnmatch's platform case behavior, so results
are identical (covered by an equivalence test against the old loop).

fix(mcp): make stdio MCP-produced files resolvable via virtual sandbox paths (#3597) (#3600)
* fix(mcp): migrate local MCP-produced files into sandbox outputs (#3597)

Stdio MCP servers (e.g. Playwright) write files to host paths that the
sandbox/artifact API cannot resolve, since it only serves paths under
/mnt/user-data. Copy local files referenced by ResourceLink results into
the thread's sandbox outputs dir and rewrite their URIs to
/mnt/user-data/outputs/... so they become readable.

Also scope pooled MCP sessions by user_id:thread_id instead of thread_id
alone, matching the per-(user_id, thread_id) filesystem isolation.

* fix(mcp): restrict file migration to trusted source roots (#3597)

Add a source-root allowlist to the MCP file-migration path so a
malicious or buggy MCP server cannot have us copy arbitrary host files
(e.g. /etc/passwd) into a thread's outputs directory, from where the
artifact API would serve them. Files are migrated only when located
under the OS temp dir (Playwright's default), the thread's own
user-data tree, or an operator-configured root via
DEERFLOW_MCP_MIGRATION_SOURCE_ROOTS.

Expand test coverage with allowlist/security cases (path escape refusal,
trusted-root acceptance), URL-encoded file:// paths, converter content
branches (image/embedded/error/structured), and copy/resolve failure
fallbacks.

* fix(mcp): harden local file migration into sandbox outputs

Address robustness and security gaps in the MCP ResourceLink file
migration:

- Set migrated files to 0o644 so a differently-UID sandbox container can
  read them, instead of inheriting the source's (possibly 0o600) mode.
- Enforce the 100MB size cap during the copy (chunked, byte-counted)
  rather than from a prior stat(), closing the grow-after-stat TOCTOU.
- Create the destination atomically with O_CREAT|O_EXCL to remove the
  check-then-create name-collision race.
- Document the shared-$TMPDIR multi-tenant read surface and mitigation.

Add regression tests: symlink escape refusal, explicit $TMPDIR source
migration, 0o644 mode, and the outputs/user-data resolve() OSError
fallback branches.

* fix(mcp): migrate playwright text file outputs

* fix(mcp): translate MCP file outputs to virtual paths instead of copying (#3597)

Pin stdio MCP subprocess cwd and TMPDIR/TMP/TEMP under the thread workspace
so produced files always land in the mounted user-data tree, then rewrite
returned references via deterministic host->virtual path translation. Free
text is best-effort only: a reference is rewritten only when it resolves to
an existing file inside the thread's tree, and bare filenames are matched
against files created/modified by the same tool call. Replaces the previous
copy-into-outputs + regex approach (which missed cases like temp/page-*.yml).

* style(mcp): apply ruff format to mcp path translation tests

* perf(mcp): offload stdio FS work off event loop and gate on transport

Address review on #3600:
- Wrap the workspace dir prep, snapshot diff, and per-token path
  resolution in asyncio.to_thread so they no longer block the event
  loop (matches the repo's blocking-IO gate convention).
- Gate the cwd/temp pinning and snapshots on stdio transport only;
  SSE/HTTP servers skip the filesystem work entirely.
- Skip the post-call snapshot diff when the result has no text content.

* test(mcp): cover stdio transport gating and text-content after-walk skip

Add unit/integration coverage for the new review-driven behavior:
- _prepare_stdio_workspace dir/temp/snapshot bundle
- _result_has_text_content detection (text, embedded text, image, empty)
- non-stdio transport skips cwd/temp pinning and touches no workspace dirs
- post-call snapshot diff is skipped without text content and runs with it

* fix(mcp): address stdio path rewrite review feedback

- Restrict the stdio MCP temp directory to 0700 instead of 0777.
- Preserve operator-provided stdio cwd values while keeping injected cwd values as strings.
- Add debug logging for deterministic path rewrites and bare-filename rewrite decisions.
- Document the stdio cwd/temp pinning, virtual-path translation, and user/thread session scope.
- Cover explicit cwd preservation and temp-dir permissions in session-pool tests.

perf(sandbox): cache LocalSandbox path-rewrite regexes per instance (#3647) (#3648)
* perf(sandbox): cache LocalSandbox path-rewrite regexes per instance

LocalSandbox re-sorted path_mappings and re-compiled its path-rewrite
regex on every tool call: _resolve_paths_in_command (every bash),
_resolve_paths_in_content (every write_file), and
_reverse_resolve_paths_in_output (every bash output / read_file). The
inputs are derived solely from self.path_mappings, which is assigned once
in __init__ and never mutated, so the work is identical every call.

Compile the patterns once per sandbox via functools.cached_property and
reuse them; hoist 'import re' to module scope. Behavior is unchanged —
only the per-call sort+escape+compile on the agent's hot path is removed.

Fixes #3647. Adds tests covering caching identity, unchanged rewriting,
path-segment boundary matching, and the empty-mappings pass-through.

* perf(sandbox): also cache resolved local paths and sorted mapping views

Beyond the regex compilation, _find_path_mapping, _is_read_only_path,
_resolve_path_with_mapping and _reverse_resolve_path re-sorted
path_mappings and re-ran Path(local_path).resolve() (a filesystem
syscall) on every call. Since path_mappings is immutable, cache the
resolved local root per mapping and the two sorted views via
cached_property and reuse them. Behavior is unchanged; the reverse-output
pattern builder now reuses the same resolved-path cache.

fix(channels): scope IM files and helper commands to owner (#3579)
* fix(channels): scope IM files and helper commands to owner

* fix(memory): honor bound IM owner for /memory gateway endpoints

The channel manager already attaches X-DeerFlow-Owner-User-Id for /memory
and /models, but the memory router resolved user_id solely from
get_effective_user_id(), which returns the synthetic internal user
(DEFAULT_USER_ID) for channel workers. A bound IM /memory therefore read
the default/internal memory instead of the connection owner's.

Resolve the owner via _resolve_memory_user_id(request) across all
/api/memory* endpoints: trusted internal callers act for the owner header,
browser/API callers fall back to get_effective_user_id(). Mirrors the
threads router's get_trusted_internal_owner_user_id pattern, completing
acceptance criterion #3 of #3539.

Add end-to-end tests asserting the resolved user_id (not just that the
header is sent) and that a spoofed owner header from a browser user is
ignored.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(channels): align memory bucket and reuse cached storage owner

Address PR #3579 review feedback:

- Memory router now sanitizes the trusted owner header via make_safe_user_id
  before routing, matching the channel file pipeline
  (_safe_user_id_for_run/prepare_user_dir_for_raw_id). A bound owner id needing
  sanitization now resolves to the same bucket as its files/uploads instead of
  500ing in _validate_user_id.
- _handle_chat reuses the storage_user_id cached at the top of the method for
  artifact delivery instead of re-deriving _channel_storage_user_id(msg), so
  uploads and outputs cannot drift to different buckets if a channel rewrites
  the InboundMessage in receive_file.

* fix(channels): stage unbound IM files under the run's user bucket

Address PR #3579 review feedback (#5): _channel_storage_user_id now mirrors

of returning None for unbound auth-enabled channels.

Previously an unbound msg ran under safe(platform_user_id) but staged uploads
under get_effective_user_id() in the dispatcher task (unset contextvar ->
"default"), so files landed in users/default/... while the agent read from
users/{safe_platform_user_id}/.... Bound and unbound channels now write where
the agent reads. Returns None only when no identity is available.

still described pre-PR default-bucket behaviour. Document that receive_file,
_ingest_inbound_files/ensure_uploads_dir/get_uploads_dir, and
_resolve_attachments/_prepare_artifact_delivery are owner-scoped via the user_id
kwarg, and that the bucket matches the memory bucket from _resolve_memory_user_id.

* refactor(channels): unify run identity and storage bucket resolution

Address PR #3579 review feedback (#3): _resolve_run_params no longer duplicates
the owner-resolution rule inline. After the #5 fix the inline block and
_channel_storage_user_id computed the identical sanitized-with-platform-fallback
value, so the run identity now calls the same helper, making it the single
source of truth for run_context["user_id"] and the file/artifact storage bucket.

_owner_headers stays deliberately separate: it sends the raw owner id over HTTP
for the gateway to re-resolve (no sanitize, no platform fallback), documented on
both helpers. test_run_identity_matches_storage_bucket pins the two together so
they cannot drift again.

fix(channels): make channel connect flow deterministic (#3582)
* fix(channels): make channel connect flow deterministic

* make format

* fix(channels): apply connect-code before allowed_users on telegram and wechat

The bind-bootstrap reorder shipped for slack/dingtalk only. Telegram and
WeChat still gate _check_user/allowed_users before connect-code dispatch, so
a newly allowlisted-but-unbound user is silently rejected when binding via the
browser deep-link / connect-code flow — the same deadlock the PR fixes.

- telegram: consume the /start deep-link token before the allowed_users gate.
- wechat: handle the /connect code before the allowed_users gate, and defer
  inbound file extraction + context-token tracking past the gate so blocked
  senders no longer trigger CDN downloads or token bookkeeping.

Adds regression tests for both adapters mirroring the slack/dingtalk coverage.

* fix(channels): enforce single-active-owner invariant at the DB layer

_revoke_other_active_owners did a SELECT-then-UPDATE in app code with no row
lock or constraint covering active rows. Under READ COMMITTED, two concurrent
connect-code consumes for the same (provider, external_account_id, workspace_id)
from different owners could each observe "no other active owner" and both commit
a connected row, leaving find_connection_by_external_identity nondeterministic.

- Add a partial unique index on (provider, external_account_id, workspace_id)
  WHERE status != 'revoked' (portable to SQLite >= 3.8.0 and PostgreSQL) so the
  database guarantees at most one non-revoked row per external identity.
- Reorder upsert_connection to revoke other owners' active rows before the new
  connected row is flushed (so the index is satisfied at commit), wrapped in a
  bounded rollback-and-retry loop. A losing concurrent writer now retries
  against the now-visible state instead of committing a duplicate.

Adds DB-constraint, revoked-slot-reuse, and concurrent-upsert regression tests.

* fix(channels): harden connect-status polling primitive

pollChannelConnectionUntilResolved was a free-floating recursive setTimeout
started from onSuccess with no cancellation, no per-provider dedup, a redundant
second endpoint per tick, and an unbounded loop on a non-finite expires_in.

- Extract a framework-agnostic, cancellable poller (connect-poll.ts) that polls
  only listChannelConnections() and invalidates the providers query once when the
  bind resolves, instead of fetching both endpoints every tick.
- Guard expires_in with a finite check + default window so undefined/NaN can no
  longer produce a poll loop that runs until the page closes.
- Track one active poll handle per provider in useConnectChannelProvider via a
  ref Map: a new connect cancels the prior poll for that provider, and a useEffect
  cleanup cancels all polls on unmount.

Adds unit tests for resolve-and-stop, cancellation, and non-finite-expiry.

* fix(channels): stop leaking blocked-sender content in DingTalk INFO log; document bind semantics

Moving the allowed_users gate past _extract_text meant the parsed-message INFO
log (text=%r, first 100 chars) fired for senders that allowed_users would have
rejected, defeating the filter's noise/privacy role. Move that log to after the
allowed_users gate so blocked senders' message text never reaches INFO logs.

Also document the two operator-relevant semantic changes in backend/CLAUDE.md:
connect-code dispatch runs before allowed_users (so allowed_users is no longer a
bind-time defense; the model relies on code confidentiality + 600s TTL + one-time
consumption), and the single-active-owner-per-external-identity transfer semantics
now backed by the partial unique index.

* docs(channels): note connect-code-vs-allowlist and ownership transfer in operator guide

Mirror the backend/CLAUDE.md notes in the operator-facing IM_CHANNEL_CONNECTIONS.md:
connect codes are consumed before allowed_users (so a not-yet-allowlisted user can
still complete a first bind, and allowed_users is not a bind-time defense), and an
external identity has at most one active owner with last-bind-wins transfer enforced
at the DB layer.

* refactor(channels): lift connect-code dispatch into Channel base class

Each adapter duplicated the ordering-sensitive boilerplate of extracting a
/connect code and guarding on the connection repo before its allowed_users gate.
The duplication is what let telegram/wechat drift and keep the gate ahead of the
bind. Centralize it:

- Move `_connection_repo` onto Channel.__init__ (removing 7 duplicate assignments).
- Add Channel._pending_connect_code(text), which guards on the repo and extracts
  the code, documenting that adapters MUST consult it before authorization so a
  browser-initiated bind can bootstrap a not-yet-authorized identity.
- Route slack, discord, feishu, dingtalk, wechat, and wecom through the helper.
  This also fixes a latent inconsistency where slack dispatched a bind even when
  no connection repo was configured.

Pure refactor — the full channel suite stays green; adds a direct unit test for
the base helper's contract.

* fix(channels): redact DingTalk parsed-message INFO log content

Log text_len instead of the first 100 chars of message text, so message
content never reaches INFO logs (the after-gate move already keeps blocked

PR touches dingtalk.py, letting the two PRs merge in any order conflict-free.

* fix(channels): add operational guardrails

* fix(channels): converge with #3582 to avoid merge-order conflicts

Drop this PR's DingTalk INFO-log redaction and hand it to #3582, which
already restructures that handler and will redact the same log there. This
PR no longer touches dingtalk.py, so the two PRs can merge to main in any
order without a conflict.

For WeChat, drop the contested thread_ts priority reorder (review #3) and
keep only what inbound dedupe needs: a server-stable message_id in the
inbound metadata (message_id/msg_id, no client_id per review #6). This is a
single added line inside the metadata dict, a region #3582 never touches, so
it auto-merges regardless of order.

* fix(channels): address three correctness review findings

1. Connect-code cap was racy (willem #1): _create_state ran delete-expired,
   count, and insert as three separate transactions, so concurrent connect
   POSTs from one owner could each see count < cap and all insert past it. Add
   ChannelConnectionRepository.create_oauth_state_within_cap which does
   delete+count+insert in a single transaction serialized per (owner,
   provider) — Postgres via pg_advisory_xact_lock, SQLite via the write lock
   the leading DELETE takes — and have the router use it.

2. Inbound dedupe key fell back to "" workspace (willem #3): two workspaces
   delivering without team/guild/aibotid would collapse to the same key and
   dedupe each other's messages. _inbound_dedupe_key now fails closed
   (returns None) when no workspace identifier is present.

3. Dedupe key was recorded on receipt and never released on failure
   (ShenAC #1): a transient error (DB blip, Gateway 503) left the key in place
   for the full TTL, so a provider redelivery of the same message_id — exactly
   the retry dedupe should absorb — was silently dropped. _handle_message now
   releases the key in the unexpected-exception branch so redelivery can
   recover, while keeping record-on-receipt so retries during handling are
   still deduped.

Tests: repo cap enforcement incl. concurrent-issuance non-leak; dedupe
fail-closed; dedupe key release-on-failure redelivery recovery.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(channels): address cleanup/efficiency and test review findings

Efficiency / cleanup:
- Dedupe key set drops client-generated ids (client_msg_id, client_id);
  keep only server-stable event_id/message_id/msg_id, which a provider's own
  redelivery preserves (ShenAC #6). Every provider already emits message_id.
- TTL/overflow pruning of _recent_inbound_events is now O(k): switch to an
  OrderedDict and popitem(last=False) from the front instead of scanning all
  4096 entries on every inbound (willem #4).
- Log "received inbound" only after the dedupe check so a provider retrying N
  times no longer logs N accepts; document that manager dedupe covers the
  agent run/final answer, not provider ack side-effects (willem #5, ShenAC #2).
- Slack drops the redundant `team_id or event.get("team")` fallback the caller
  already resolved (willem #6).
- create_oauth_state_within_cap prunes only this owner/provider's expired codes
  instead of a global DELETE on every connect POST; global cleanup still runs
  on consume_oauth_state (willem #7).

Tests:
- Dedupe test uses tmp_path instead of a leaked mkdtemp, uses distinct objects
  per publish, and adds a negative control: a different message_id is still
  processed, catching over-dedupe regressions (willem #8, ShenAC #4).
- Slack HTTP-mode rejection test supplies app_token so the missing-token early
  return can't mask the guard, giving the state assertions teeth (ShenAC #3).
- count_oauth_states test pins that the active row survives, not just the count
  (ShenAC #5).

fix(sandbox): stop flagging string-literal path fragments as unsafe absolute paths (#3623)
* fix(sandbox): stop flagging string-literal path fragments as unsafe paths

The host-bash absolute-path guard scans the raw command string, so /segment
sequences inside string literals, f-strings, and templates were treated as
absolute path arguments and rejected — e.g. python -c "print(f'/端口{port}')"
or a REST template /devices/{id}/port. Whether a fragment tripped the guard
depended on the character right before the slash (a word char suppressed the
match), so the same literal could pass or fail unpredictably, pushing the model
into retry loops that bloat context and wall-clock time.

Exempt matches carrying non-ASCII characters or format braces: real host paths
a command would open contain neither, so these are text, not paths. The guard
is best-effort (not a security boundary), and plain ASCII host paths like
/etc/passwd — including ones written inside a code string such as
open('/etc/passwd') — stay rejected.

* fix(sandbox): only exempt identifier-template braces, not bash brace expansion

The literal-fragment exemption exempted any path fragment containing { or },
which let bash brace expansion (cat /etc/{passwd,shadow}) and ${VAR} expansion
reconstitute real host paths past validate_local_bash_command_paths. Tighten
the brace branch to only exempt fragments where every {...} block is a single
identifier-like placeholder (/devices/{id}/port, f-string /{port}); reject
${VAR} shell-variable expansion. Add parametrized regression tests for the
brace-expansion and shell-var bypasses.

feat(community): add Serper Google Images provider for image_search (#3575)
* feat(community): add Serper Google Images provider for image_search

Add a Serper-backed `image_search` tool alongside the existing Serper
`web_search` provider, so users with a SERPER_API_KEY can pull Google
Images results as reference images for downstream image generation.

- Share request/response handling between web_search and image_search
  via `_serper_post` / `_response_items`, with bounded `max_results`
  (capped at 10) and query normalization.
- Add a best-effort SSRF guard (`_safe_public_url`) that rejects
  non-http(s), localhost and private/non-global IP image URLs; filtered
  entries are dropped and never consume the result limit.
- doctor: flag literal `api_key` values in config as a warning and steer
  users toward `.env` + `$SERPER_API_KEY`.
- Docs/config: document the Serper image_search provider and SERPER_API_KEY,
  and discourage committing literal keys to config.yaml.
- Tests: cover the provider end-to-end (100% line coverage on tools.py)
  and the doctor literal-key warning path.

* fix(community): block obfuscated IPv4 literals in Serper image SSRF guard

The image_search SSRF guard only rejected dotted-decimal IP literals; encoded
forms such as decimal (http://2130706433/), hex (0x7f000001) and octal
(0177.0.0.1) raised ValueError in ip_address() and were allowed through, even
though many HTTP clients resolve them to private addresses like 127.0.0.1.

Add _decode_ipv4() to permissively decode these inet_aton-style encodings and
apply the same is_global check; hostnames that do not decode to an IP (e.g.
cafe.com) are still treated as hosts and left to fetch-time re-validation.

Addresses PR review feedback. Tests cover decimal/hex/octal loopback and
private encodings plus non-IP edge cases; tools.py stays at 100% line coverage.

* test(community): cover IPv4-mapped IPv6 URL filtering

* fix(community): address Serper image search review feedback

- Block trailing-dot hostname SSRF bypass (localhost./127.0.0.1.) in
  _safe_public_url by stripping the FQDN root label before checks.
- Keep a filtered image/thumbnail URL empty instead of collapsing onto
  its counterpart, preserving the high-res/preview contract.
- Evaluate the SSRF guard once per field rather than twice.
- Treat a null-typed organic/images field as "no results" rather than a
  malformed payload.
- doctor.py: when a config $VAR is unset, fall through to the default env
  var before reporting it as not set.

fix(sandbox): return actionable hint when read_file hits a binary file (#3624)
read_file decodes with UTF-8. Binary uploads (.xlsx, images, ...) raise
UnicodeDecodeError in the sandbox layer. UnicodeDecodeError is a ValueError
subclass, not an OSError, so it bypassed the typed handlers and fell through
to the generic except, surfacing a vague "Unexpected error reading file"
message. The model could not tell the file was binary, so it retried
read_file instead of switching to bash + pandas/openpyxl, burning LLM
round-trips and bloating context with repeated failures.

Add a dedicated UnicodeDecodeError handler that tells the model the file is
binary and to use bash with a suitable library (or view_image for images).

feat(subagents): attribute subagent spans to parent thread's Langfuse session (#3611)
The subagent execution path did not call inject_langfuse_metadata(...)
and built its model with attach_tracing=True, so subagent LLM/tool
spans landed in Langfuse as isolated top-level traces carrying fresh
session ids and the default user. They were findable in the unfiltered
trace list but did not group under the parent thread's session card,
and Langfuse cost attribution for subagent traffic did not line up
with the parent conversation — even though DeerFlow's internal token
accounting (SubagentTokenCollector) was already correct.

Extend the lead-agent tracing wiring to the subagent path so a single
subagent run produces one trace that shares the parent thread's
session_id and user_id, with a subagent:<name> trace name:

- subagents/executor.py: append build_tracing_callbacks() output to
  run_config["callbacks"] (preserving SubagentTokenCollector) and
  call inject_langfuse_metadata(...) with thread_id, user_id, and
  the normalized subagent:<name> trace name. Build the model with
  attach_tracing=False so model-level tracing does not double-count
  with the graph-root callbacks — the same pairing the lead agent
  uses.
- tools/builtins/task_tool.py: resolve user_id via
  resolve_runtime_user_id(runtime) at the parent tool layer (before
  the background thread starts) and thread it through
  SubagentExecutor.__init__, because the _current_user contextvar
  is not guaranteed to survive the _execution_pool boundary.

Trace topology is unchanged: subagent traces remain separate top-level
traces in the same session, not nested as child spans under the lead
trace (Plan B follow-up).

Tests: tests/test_subagent_executor.py::TestSubagentTracingWiring
covers the callback append, the session/user/trace-name injection,
the disabled-langfuse no-op, the DEFAULT_USER_ID fallback, the
empty-name trace-name fallback, and the env-tag emission. Existing
test_create_agent_threads_explicit_app_config_to_model_and_middlewares
now also asserts attach_tracing=False.

Docs: CLAUDE.md Tracing System section documents subagents/executor.py
as a third injection point alongside worker.py and client.py.

fix(sandbox): create shell session before retrying on a fresh id (#3577)
* fix(sandbox): create shell session before retrying on a fresh id

The AIO sandbox recovery path generated a UUID and passed it straight to
exec_command(id=...). The sandbox image only auto-creates a session when
exec_command is called with *no* id; an exec carrying an unknown id returns
HTTP 404 "Session not found". So every ErrorObservation recovery itself
404'd, turning a transient session lapse into an unrecoverable tool error
that looped the run up to the LangGraph recursion limit.

Explicitly create_session(id=fresh_id) before targeting that id on retry.
create_session is idempotent (returns the existing session if the id already
exists), so this is safe under the serializing lock.

Updated the regression test to assert the retry targets exactly the
created session id rather than a fabricated, uncreated one.

* fix(sandbox): release the one-shot recovery session after retry

The fresh session created on the ErrorObservation recovery path is used for
exactly one command -- the next execute_command runs with no id and returns
to the default session. Under persistent session corruption every command
would create another session that is never reused or released, accumulating
sessions on the container.

Release it best-effort with cleanup_session() in a finally, swallowing any
cleanup error so it never masks a successful retry.

Addresses review feedback on #3577.

Address review findings on the runtime-provider-state change:

- configure/disconnect now re-read the live app.state.channels_config
  after the worker await and mutate only the affected provider key in
  place, so a concurrent mutation for a different provider is no longer
  clobbered by a stale pre-await snapshot.
- disconnect revokes DB connection rows before committing the store and
  cache, so a repo failure cannot leave the store/cache "disconnected"
  while the DB keeps "connected" rows a later re-configure would
  silently reactivate.
- _provider_response preserves non-connected statuses (e.g. revoked)
  when the provider is unavailable, only masking a stale "connected"
  row as not_connected.

* refactor _requires_bound_identity()

* make format

* fix: reject unbound channel chats before semaphore

* security enhancement

* fix: enforce bound-identity admission at command entry point

The bound-identity gate only ran for non-command messages in
_handle_message() and as a fallback inside _handle_chat(). Commands had
no equivalent boundary, so an unbound platform user could send /new and
reach _create_thread() directly, creating an unowned Gateway thread and
empty checkpoint. Info commands (/status, /models, /memory) likewise
leaked Gateway state to unbound users.

Add the same _requires_bound_identity() check at the top of
_handle_command(), rejecting via _reject_unbound_channel_message() before
any thread creation or Gateway query. The gate is a no-op in legacy
open-bot mode (require_bound_identity=False) and auth-disabled mode.
Provider-level binding flows (/connect, /start) are consumed by the
provider adapter before reaching the manager, so they are unaffected.

Tests:
- unbound auth-enabled /new is rejected before threads.create
- bound auth-enabled /new still creates the thread

fix(subagents): raise general-purpose max_turns to 150 and default timeout to 30min (#3610)
* fix(subagents): raise general-purpose max_turns to 150 and default timeout to 30min

Deep-research subtasks failed out of the box with GraphRecursionError (Recursion limit of 100 reached): the built-in general-purpose subagent caps at max_turns=100. Raise it to 150 and bump the default subagent timeout from 900s (15min) to 1800s (30min) so the extra turns have time to run instead of shifting the failure to a timeout. The lead agent recursion_limit (100) is unchanged; the failures are subagent-only.

* docs(subagents): clarify lead recursion_limit is independent of subagent max_turns

Add comments at both lead recursion_limit=100 sites (gateway services + channel manager) explaining the lead's LangGraph super-step budget is separate from subagent depth, so the two 100s are not conflated. Comment-only, no behavior change.

fix(agents): sync agent_name across context/configurable and reject empty soul (#3549) (#3553)
* fix(agents): sync agent_name across context/configurable and reject empty soul (#3549)

Two independent issues caused custom agent creation to silently fail:

1. build_run_config only wrote agent_name into one container (configurable
   or context), so setup_agent — which reads ToolRuntime.context exclusively
   since LangGraph >=1.1.9 — saw agent_name=None and wrote SOUL.md to the
   global base_dir instead of users/{user_id}/agents/{name}/. Mirror the
   dual-write pattern already used by merge_run_context_overrides and
   naming.py so both containers always carry the same value.

2. setup_agent persisted whatever soul string it received, including empty
   or whitespace-only content, and still reported success. The frontend
   then surfaced an unusable agent and the global default SOUL.md could be
   silently overwritten with empty content. Reject empty soul before any
   filesystem operation so the model can retry.

Tests:
- test_gateway_services.py: dual-write regressions for both configurable
  and context entry paths, explicit-agent-name precedence on both sides,
  and a shape-parity test against merge_run_context_overrides.
- test_setup_agent_tool.py: empty/whitespace soul rejection, plus
  no-overwrite guarantees for existing global and per-agent SOUL.md.

fix(history): strip base64 image data from REST endpoint responses (#3535)
ViewImageMiddleware persists full base64 image payloads in hide_from_ui
human messages inside checkpoints. All REST endpoints that returned
serialize_channel_values(channel_values) sent these multi-megabyte
payloads to the frontend, freezing the UI on threads with images.

Add strip_data_url_image_blocks() to remove data:-scheme image_url
content blocks from hide_from_ui messages, and
serialize_channel_values_for_api() as a convenience wrapper used by all
six affected call sites across threads, runs, and thread_runs routers.
SSE streaming is unaffected (still uses serialize_channel_values).

Fixes #3496

perf(runtime): index messages in MemoryRunEventStore to avoid O(n) scans (#3531)
list_messages re-scanned every event in the thread on each call (category
filter + seq filter) — O(total events) per paginated request on the default
run-events backend. Maintain a messages-only, seq-sorted projection of _events
(shared dict refs, no copies) and locate the seq window with bisect:
list_messages drops to O(log m + page) and count_messages to O(1). The index is
kept in lockstep at every mutation site (put / put_batch via _put_one,
delete_by_run, delete_by_thread).

Externally observable behavior is unchanged — the full RunEventStore contract
suite passes across memory/db/jsonl.

Add a test covering pagination over non-contiguous message seqs (messages
interleaved with trace events), including in-gap and exact-boundary cursors.

perf(runtime): index runs by thread_id to avoid O(n) scans in RunManager (#3499)
* perf(runtime): index runs by thread_id to avoid O(n) scans in RunManager

RunManager.list_by_thread, create_or_reject (inflight check), and has_inflight each filtered every in-memory run by thread_id — an O(total in-memory runs) scan that grows with overall gateway traffic rather than the queried thread's depth.

Add a thread_id -> run_ids secondary index (an insertion-ordered dict used as an ordered set) maintained in lockstep with _runs under the existing lock at every add/remove site (create, create_or_reject, both rollbacks, cleanup). The three per-thread queries now run in O(runs-in-thread); insertion order is preserved so list_by_thread keeps stable tie-breaking. Behavior unchanged. Adds 6 regression tests; full RunManager suite 146 passed.

* test(runtime): cover create_or_reject rollback + clarify thread-index guard docstrings

Address review on #3499 (fancyboi999):
- Reword _thread_records_locked docstring: lockstep under self._lock is the
  correctness guarantee; self._runs.get is one-directional defense-in-depth
  (drops stale ids, cannot recover index-missing ids), not reconciliation.
- Add test_failed_create_or_reject_unindexes_run covering the create_or_reject
  rollback/unindex mutation site (the last untested mutation path).
- Fix _FailingPutRunStore docstring ("initial put" -> "every put").

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(skills): keep skill archive installation off the event loop (#3505)
* fix(skills): keep skill archive installation off the event loop

ainstall_skill_from_archive — the async entry point awaited by the gateway
POST /skills/install route — ran its entire filesystem pipeline inline on
the event loop: zip extraction, frontmatter validation, rglob enumeration,
per-file read_text, shutil.copytree staging, and tempdir cleanup.

Restructure into offloaded phases: prepare (extract + validate) and commit
(stage + move) run via asyncio.to_thread, the tempdir lifecycle is
offloaded, and the security scanner's file enumeration and reads move off
the loop — only the per-file LLM scan (genuinely async) stays awaited.
Security decision logic and exception contract are unchanged.

Anchor: tests/blocking_io/test_skills_install.py drives the real install
pipeline (real .skill archive, real FS; only scan_skill_content stubbed)
under the strict Blockbuster gate. Verified red on pre-fix code
(BlockingError: os.stat), green with the fix.

* fix(skills): log temp-dir cleanup failures instead of swallowing them

Review follow-up on the install offload: rmtree(ignore_errors=True) kept
the primary install exception but silently leaked the extraction dir on
cleanup failure. Keep the never-mask behaviour, add a warning log.

* fix(skills): bound install tmp cleanup and pass skill_dir explicitly (review)

- Wrap the best-effort temp-dir cleanup in asyncio.wait_for (5s) so a
  hung filesystem in the finally block cannot stall or mask the install
  outcome; timeout is logged like the existing OSError path.
- Hoist _collect_scannable_files to module level with skill_dir as an
  explicit argument instead of a closure capture.

feat(community): add SearXNG and Browserless web search/fetch tools (#3451)
* feat(community): add SearXNG and Browserless web search/fetch tools

- SearXNG web_search: privacy-focused meta search engine integration
  with configurable base_url via config.yaml tool settings
- Browserless web_fetch: headless browser page fetching with
  readability article extraction
- Both tools are fully configurable through tool config section
- No external API keys required for basic operation

* fix: address PR review feedback and add unit tests

- Guard config.model_extra against None values (review #1, #2)
- Coerce max_results to int when reading from config (review #2)
- Fix web_fetch_tool to use direct HTTP fetch instead of reusing
  the web_search client config (review #3)
- Fix misleading docstring for SearxngClient.fetch (review #4)
- Remove unused target_url variable to pass Ruff lint (review #5)
- Normalize bool config values with _normalize_bool helper to
  handle env-resolved string values correctly (review #6)
- Add unit tests for both SearXNG and Browserless client classes
  and their tool functions with mocked httpx (review #7, #8)

* fix: convert to async httpx to avoid blocking I/O on event loop

- Replace httpx.Client with httpx.AsyncClient in both client classes
- Convert tool functions to async def
- Wrap readability_extractor calls in asyncio.to_thread()
- Update all tests to use pytest.mark.asyncio and async mocks
- Fix import sorting to pass Ruff lint

* fix(browserless): replace deprecated waitUntil with waitForEvent

The Browserless API has deprecated the waitUntil parameter.
Replace with waitForEvent which accepts values like 'networkidle'.
Default is empty (no wait), configurable via config.yaml.

* fix(browserless): remove deprecated gotoTimeout and bestAttempt params

The Browserless /content API does not accept gotoTimeout or bestAttempt
as top-level payload keys. These were being sent unconditionally,
causing 400 Bad Request errors on current Browserless versions.

Changes:
- Remove goto_timeout_ms parameter and 'gotoTimeout' from payload
- Remove best_attempt parameter and 'bestAttempt' from payload
- Remove _normalize_bool helper (no longer needed)
- Remove goto_timeout_ms and best_attempt config reading in tools.py
- Add tests for waitForSelector and reject params
- Verify no deprecated params are sent in test_fetch_html_success

* refactor(searxng): remove web_fetch_tool, decouple from web_search config

SearXNG is a search engine — it should only provide web_search_tool.
The web_fetch responsibility belongs to Browserless (headless Chrome)
or Jina AI, not SearXNG.

Changes:
- Remove web_fetch_tool from SearXNG tools.py and __init__.py
- Remove SearxngClient.fetch() method (no longer needed)
- Remove unused asyncio/readability imports from SearXNG tools.py
- Add test for max_results string-to-int coercion from config
- Add test for search with categories parameter
- Add test for httpx.RequestError handling
- Apply ruff format fixes to browserless_client.py and test files
