feat(browser): add agentic browser control (#4187)
* feat(browser): add agentic browser control

* 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.

* fix(frontend): smooth streaming in long tool threads

* 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(browser): harden worker and session lifecycle

* fix(browser): address latest review feedback

* fix(frontend): preserve optimistic new-chat message

* test(e2e): preserve mocked message run ids

* fix(browser): address capability review feedback

fix(auth): let deployments close local self-registration (#4311)
* fix(auth): let deployments close local self-registration

The OIDC provisioning policy (allowed_email_domains, require_verified_email,
auto_create_users) is enforced only in the SSO callback via
get_or_provision_oidc_user. POST /api/v1/auth/register creates a local account
without consulting any of it, and nothing can turn that path off, so a
deployment declaring an email-domain allowlist can still be joined by any
address through local registration.

Add auth.local.allow_registration (default true, so existing deployments are
unchanged) and gate /register on it before the account is created. Report the
flag from /setup-status so the login page stops offering a signup entry the
Gateway will reject.

/initialize is deliberately not gated: it is the bootstrap path, guarded by
admin_count == 0, and closing it would leave a fresh install unable to create
its first admin.

An unreadable config.yaml falls back to the pre-gate default (open) rather than
making these two endpoints a hard dependency on the file.

fix(gateway): correct GitHub auto-retry claim in webhook route docs (#4289)
While investigating a review on PR #4274 (which corrected the same
misconception in the channel manager's dedupe-TTL comment), I found a
more elaborate version of the same factual error in this route,
predating that PR: the docstring claimed "GitHub retries 5xx deliveries
with exponential backoff (up to ~5 attempts over ~8 hours)". No such
behavior exists. Verified directly against GitHub's documentation:
failed deliveries (5xx, timeout, connection error alike) are simply
recorded as failed and never automatically redelivered, for both
repository and GitHub App webhooks
(https://docs.github.com/en/webhooks/using-webhooks/handling-failed-webhook-deliveries).
Redelivery is always explicit: the "Redeliver" button, the REST API, or
an operator's own recovery script (GitHub's own recommended pattern for
the latter runs on a 6-hour cron, illustrating this is opt-in operator
tooling, not a GitHub-side mechanism).

The 503-vs-200 status code choice itself was already correct and is
unchanged: 503 keeps a transient failure recorded as failed so it can be
recovered via one of the explicit paths above, while 200 correctly
marks permanent/non-retryable conditions (disabled channel, unknown
event, missing service) as done so no pointless redelivery is invited.
Only the rationale text describing *why* was wrong.

- github_webhooks.py: reworded the route docstring and four inline
  comments/log messages that repeated "GitHub retries" / "so GitHub
  retries" framing, citing the actual documented behavior.
- test_github_webhooks.py: renamed
  test_dispatch_failure_returns_503_so_github_retries to
  test_dispatch_failure_returns_503_not_200 and reworded its docstring
  plus two nearby docstrings/comments with the same framing. No
  assertions changed - same status codes and response bodies checked.
- AGENTS.md: corrected the GitHub Webhooks router table row to match.

All 44 tests in test_github_webhooks.py pass, plus the full
test_github_dispatcher.py / test_github_channel.py /
test_github_registry.py / test_channels.py suites (313 total). ruff
check and ruff format --check are clean on both touched Python files.

fix(gateway): handle null config.configurable in _resolve_thread_id (#4301)
* fix(gateway): handle null config.configurable in _resolve_thread_id

`_resolve_thread_id` read the thread id with
`(body.config or {}).get("configurable", {}).get("thread_id")`. The
`.get("configurable", {})` fallback only applies when the key is absent.
`RunCreateRequest.config` is typed `dict[str, Any] | None`, so a client
can send `{"config": {"configurable": null}}`; the key is then present
with value `None`, and `None.get("thread_id")` raises `AttributeError` —
an unhandled HTTP 500 on `POST /api/runs/stream` and `/api/runs/wait`.

Coalesce the inner value with `or {}` so a null `configurable` yields a
freshly generated thread id, matching the docstring ("or generate a new
one") and the behaviour of `config: null` / `configurable: {}`. The
sibling `_checkpoint_configurable` in thread_runs.py already guards the
same field defensively. Behaviour is byte-for-byte identical for every
input that worked before.

fix(channels): document GitHub dedupe TTL, tighten redelivery tests (#4274)
* fix(channels): document GitHub dedupe TTL, tighten redelivery tests

Follow-up to PR #4104's review, whose non-blocking notes were left
unaddressed at merge time:

- Document the previously-undocumented inbound-dedupe TTL
  (INBOUND_DEDUPE_TTL_SECONDS, 10 min, in-memory only) directly above
  the constant in ChannelManager: what it is, why the window, and what
  happens at the boundary (a manual "Redeliver" clicked after the TTL
  has elapsed, or any redelivery after a Gateway restart, is not
  deduped, since _recent_inbound_events is never persisted to
  ChannelStore). Cross-reference it from the GitHub dispatcher's
  fan-out comment, which previously implied unconditional redelivery
  coverage.
- test_channels.py::test_github_redelivery_is_deduped_like_other_channels:
  the _gh helper stamped a 2-part delivery:agent id while production
  stamps a 3-part delivery:user:agent id. Align the helper with the
  real shape and add a cross-user assertion the old 2-part shape could
  not even express.
- test_github_dispatcher.py::test_missing_delivery_header_leaves_dedupe_open:
  previously only asserted the dispatcher-layer id was None. Add the
  manager-level _is_duplicate_inbound assertion across two header-less
  deliveries so a future regression that treats a missing id as a real
  key is caught here too, not only at the dispatcher layer.

All four affected test files (test_github_dispatcher.py,
test_channels.py, test_github_channel.py, test_github_registry.py)
pass; ruff check and ruff format --check are clean. Verified the two
tightened tests actually discriminate by temporarily reintroducing
each bug they target (2-part id shape; missing-id treated as a real
key) and confirming the new assertions fail, then reverting.

* fix(channels): correct GitHub redelivery claim in dedupe comments

fancyboi999's review on this PR flagged that the previous commit's new
comments (manager.py, dispatcher.py) justified the 10-minute dedupe TTL
by claiming GitHub automatically retries a failed delivery after its
10-second timeout. GitHub's own documentation says the opposite:
failed deliveries (non-2xx, timeout, connection error) are recorded as
failed and never automatically redelivered, for both repository and
GitHub App webhooks alike. Every redelivery is explicit: the "Redeliver"
button, the REST API, or an operator's own recovery script.

- manager.py: rework the INBOUND_DEDUPE_TTL_SECONDS comment to state
  GitHub's actual behavior (no auto-retry), cite the authoritative doc
  (docs.github.com/en/webhooks/using-webhooks/handling-failed-webhook-deliveries),
  and justify the 10-minute window as a bound on explicit near-term
  replays rather than an automatic-retry window. No longer asserts
  unverified retry behavior for the other channels either.
- dispatcher.py: same correction for the dedupe_message_id comment,
  which previously implied "retried after a timeout" as a distinct,
  automatic case alongside the manual "Redeliver" button.
- test_channels.py / test_github_dispatcher.py: reworded the two
  docstrings and one section comment that repeated the same
  "retry-on-timeout" framing, so the corrected mental model doesn't
  sit next to contradicting prose nearby. No assertions changed.

Verified directly against GitHub's current documentation (fetched, not
paraphrased from memory): "Handling failed webhook deliveries" states
plainly that GitHub does not auto-redeliver; "Automatically redelivering
failed deliveries for a GitHub App webhook" / "...for a repository
webhook" are both guides for a user-written recovery script (GitHub's
own example runs on a 6-hour cron), not a native GitHub feature. No
difference in this behavior between GitHub Apps and repository webhooks.

All four affected test files pass; the two `test_bot_login_whitespace_only`
/ `test_trigger_mention_login_whitespace_only` failures in
test_github_dispatcher.py are pre-existing on this branch's unmodified
HEAD (confirmed against a clean checkout of the same commit) and are
unrelated to this change. ruff check and ruff format --check are clean
on all four touched files.

fix(uploads): claim the converted markdown filename before writing it (#4288)
* fix(uploads): claim the converted markdown filename before writing it

* doc(changelog): record the converted-markdown filename collision fix

Covers both surfaces that report markdown_file: the gateway uploads route
and DeerFlowClient.upload_files.

* fix(uploads): release the claimed markdown name when conversion fails

Claiming the companion .md name before conversion means a conversion that
writes nothing leaves the name reserved for the rest of the request, so a
later same-stem upload is renamed against a name nothing occupies. Uploading
notes.docx (conversion fails) + notes.md stored the user's file as notes_1.md
with no notes.md on disk, where main kept notes.md.

Discard the claim when conversion returns None, at both call sites that
pre-claim it. Covers both victims: a later same-stem .md upload, and the next
convertible's companion.

fix(artifacts): serve inline binary artifacts via FileResponse for Range support (#4281)
* fix(artifacts): serve inline binary artifacts via FileResponse for Range support

Audio/video/image artifacts that are previewed inline (not downloaded, not
active content) were served by reading the whole file into memory and
returning it through a plain Response. That response never sets
Accept-Ranges and ignores any Range header the browser sends, so seeking
an <audio>/<video> element backed by this endpoint always gets the full
200 response back instead of a 206 partial response for the requested byte
range -- which is why dragging the seek bar on an audio artifact restarts
playback from the beginning instead of jumping to the new position.

Route this case through FileResponse instead (as the active-content/
download branch already does), which handles Range/If-Range natively.
Verified with a real Range request against the endpoint: initial load now
reports Accept-Ranges: bytes, and a ranged GET returns 206 with the correct
Content-Range and only the requested slice of bytes.

Fixes #3240

* fix(artifacts): address review nits on the inline FileResponse branch

Two non-blocking nits from review:

- Drop the redundant filename= kwarg on the inline_file FileResponse
  call. Content-Disposition is already set explicitly on this branch,
  and FileResponse only uses filename to setdefault that same header
  -- which is a no-op once it's already present. Harmless today, but
  removes the latent risk that a future Starlette version turning that
  setdefault into a hard set would silently flip inline preview to
  attachment.
- Reword the blocking-IO regression-anchor docstring: it claimed
  awaiting get_artifact for a binary artifact does "zero filesystem
  IO", but _read_artifact_payload still runs exists/is_file/
  mimetypes.guess_type/is_text_file_by_content (an 8 KB read) for
  binary files too, just offloaded via asyncio.to_thread like the text
  branch. The gate has nothing to catch because that IO is off the
  event loop, not because there's none -- reworded to say no full-file
  read happens, matching the accurate framing already used one
  paragraph up.

tests/test_artifacts_router.py, tests/blocking_io/test_artifacts_router.py
(19 tests) are green, and ruff check/format are clean on both changed
files.

fix(mcp): offload blocking filesystem IO in MCP config update (#3552)
* fix(mcp): offload blocking filesystem IO in MCP config update

update_mcp_configuration resolved the extensions config path, probed its
existence, read the raw JSON, wrote the merged config, and reloaded it — all
blocking filesystem IO on the event loop (PUT /api/mcp/config). The whole
read-modify-write after the async admin check has no interleaved awaits, so it
moves into one _apply_mcp_config_update helper dispatched via asyncio.to_thread;
the masked response is built on the loop. The secret-preserving merge, error
codes, and the stdio command allowlist are unchanged.

Found via `make detect-blocking-io`. Same class as #3457 / #3529 / #3551.

strict Blockbuster gate.

Address review on #3552: offloading the read-modify-write to a worker thread
dropped the implicit serialization the single-threaded event loop provided, so
two concurrent PUT /api/mcp/config calls could interleave and clobber each
other. Guard the offloaded RMW with a module-level asyncio.Lock to restore
within-process atomicity (cross-process writers remain a separate, pre-existing
concern).

Add a serialization regression test (red->green: without the lock the tracked
max concurrency exceeds 1).

fix(gateway): keep create_thread idempotent when the insert loses a race (#3800)
* fix(gateway): keep create_thread idempotent when the insert loses a race

The /api/threads create endpoint checks for an existing row and then
inserts, but the two steps are not atomic. When two requests create the
same thread_id concurrently, one commits first and the other's INSERT
fails on the duplicate primary key. The SQL-backed thread store raises,
the handler catches it as a generic failure, and the loser gets a 500 —
even though the docstring promises the call is idempotent.

Re-read the row after a failed insert: if it is now present (the
competing request won), return it instead of surfacing the conflict. A
genuine write failure where the row is still absent keeps the 500.

Covered by a regression test that simulates the lost race and asserts
the endpoint returns the existing thread rather than erroring.

Signed-off-by: Yufeng He <40085740+he-yufeng@users.noreply.github.com>

* fix(gateway): scope create_thread race recovery and mirror owner reconciliation

Address review on #3800:

- Scope the insert-race recovery to sqlalchemy IntegrityError instead of a
  broad `except Exception`, so a non-race failure that coincides with an
  existing row is no longer silently returned as a 200. Any other error logs
  and surfaces as a 500. (The memory store overwrites on duplicate rather than
  raising, so it never reaches this path.)

- Route both the fast path and the recovery path through a shared
  `_resolve_existing_thread` helper so the recovery performs the same trusted-
  owner reconciliation (claiming a legacy unscoped `user_id=None` row) the fast
  path does. Thread ownership no longer diverges based on which path resolved
  the record.

Add regression tests for both: the recovery claims an unscoped row for a
trusted owner, and a non-IntegrityError failure surfaces as a 500.

fix(memory): flush memory queue on graceful shutdown to prevent loss (#4181)
* fix(memory): bounded shutdown flush via MemoryManager.shutdown_flush

Re-applies the memory-queue shutdown drain on top of the pluggable
MemoryManager abstraction (#4122): the old top-level MemoryUpdateQueue
singleton is gone, so the drain is now a backend contract instead of
host code reaching into the queue.

- MemoryManager ABC: shutdown_flush(timeout) -> bool. Every backend
  implements a bounded graceful-shutdown drain.
- DeerMem: queue.flush_sync (daemon-thread + Event.wait hard timeout
  for the uninterruptible sync LLM call; joins an in-flight worker
  first so contexts a debounce Timer already pulled out are not lost on
  exit; skips inter-item sleep on the drain path; per-item
  succeeded/failed count), exposed via shutdown_flush.
- noop: shutdown_flush is a clean no-op success.
- Gateway lifespan: call get_memory_manager().shutdown_flush(timeout)
  after channels/scheduler stop, via asyncio.to_thread, try/except
  bounded. No host-level pending/processing guard -- the backend
  short-circuits on an idle buffer, so the host cannot "forget" the
  in-flight case (structurally eliminates the guard race flagged on the
  prior revision).
- shutdown_flush_timeout_seconds added to the shared MemoryConfig
  (host-owned lifecycle budget, default 30, 1-300) + exposed on
  MemoryConfigResponse and the embedded client; config_version 25 -> 26.

Tests: queue flush_sync (7), lifespan drain incl. False-branch caplog
assertion + disabled gate (3), ABC contract noop/deermem (3).

* fix(chart): gateway grace period so memory drain is not SIGKILLed

K8s defaults terminationGracePeriodSeconds to 30s, shorter than the
Gateway's graceful-shutdown work (channel stop ~5s + memory queue drain
default 30s). Without an explicit grace period, K8s SIGKILLs the memory
drain mid-flight and silently re-introduces the loss shutdown_flush is
fixing (flagged on the prior revision).

- gateway pod: terminationGracePeriodSeconds (default 45, configurable).
- gateway container: preStop sleep (default 5, 0 disables) so the
  Service/ingress deregisters the pod before SIGTERM begins the drain.
- values.yaml + README: both configurable; README documents that the
  grace period must track memory.shutdown_flush_timeout_seconds.

* docs(memory): document shutdown_flush_timeout_seconds + lifespan drain

Add the host-shared field to the memory config list and Config Schema
summary in backend/AGENTS.md, noting the lifespan drain and the K8s
grace-period relationship.

* fix(chart): bump embedded config_version to 26

The chart's embedded `config:` block (values.yaml + README example) still
had config_version: 25 after commit f3ca8e9f raised config.example.yaml to
26, failing the validate-chart config_version drift check. Bump both to 26.

fix(channels): dedupe GitHub webhook redeliveries (#4104)
* fix(channels): dedupe GitHub webhook redeliveries

The inbound dedupe added for the IM channels in #3584 keys
ChannelManager._is_duplicate_inbound on a top-level metadata["message_id"]
plus a workspace id. The GitHub channel added later in #3754 never
populated either: the X-GitHub-Delivery GUID was buried in
metadata["github"]["delivery_id"] and no workspace id was set, so every
GitHub delivery produced a None dedupe key and was never deduped.

GitHub reuses the same X-GitHub-Delivery GUID when a delivery is retried
after a timeout or replayed via the repo/App "Redeliver" button, so a
redelivery re-ran the agent with real side effects (e.g. a duplicate PR
comment) while the other channels absorbed an identical redelivery.

fanout_event now stamps the dedupe identity the manager already consumes:
- workspace_id = repo (globally unique, always present; mirrors
  Telegram/WeChat keying the workspace on the chat id)
- metadata["message_id"] = f"{delivery_id}:{agent.name}"

A single delivery fans out to N agents, so the id is scoped to
(delivery, agent): an identical redelivery reproduces the same pairs
(deduped) while two agents matching the same delivery keep distinct ids
and both still fire. When the delivery header is absent the id is left
None, so the manager fails open exactly as before.

Tests: dispatcher-level coverage that the identity is stamped, stable
across redelivery, and distinct per agent/delivery; a ChannelManager
regression that an identical GitHub redelivery dispatches once while a
new delivery and a second agent on the same delivery still fire.

* fix(channels): scope GitHub dedupe id by owning user

_inbound_dedupe_key indexes on (channel, workspace_id, chat_id,
message_id). For GitHub, workspace_id and chat_id are both the repo,
so the owning user was never represented anywhere in the key -
fanout_event stamped the id as f"{delivery_id}:{agent.name}".

Two different users each binding an agent of the same name (e.g.
"reviewer") to the same repo+event therefore produced an identical
dedupe id for both fan-out messages. ChannelManager._is_duplicate_inbound
treated the second as a replay of the first and silently dropped it,
even though GitHub delivered the webhook once and both users' agents
legitimately matched.

Fold match.user_id into the id: f"{delivery_id}:{match.user_id}:{agent.name}".
Genuine redeliveries (same user, same agent, same delivery) still
produce the same id and are deduped; two agents - same-named or not,
same user or not - on one delivery now always keep distinct ids.

Tests: new cross-user regression pins that two users' same-named
agents both dispatch instead of the second being deduped against the
first; the existing per-(delivery, agent) test and the literal id
assertion in test_delivery_id_populates_inbound_dedupe_identity are
updated for the new id shape.

* fix(channels): point cross-user dedupe comment at its regression test

Replace the inline reviewer-handle attribution with a pointer to
test_dedupe_identity_distinguishes_same_agent_name_across_users, which
ages better than a person's name in committed code.

feat(memory): pluggable memory abstraction with self-contained DeerMem backend (#4122)
* feat(memory): pluggable + self-contained memory system (MemoryManager plan phases 1 & 2)

Phase 1 — Pluggable (steps 0-10):
- ABC MemoryManager (9 methods) + singleton factory + drop-in backend discovery
- DeerMem default backend with core/ (storage/queue/updater/prompt/message_processing)
- NoopMemoryManager backend (proves pluggability)
- All call sites (middleware/hook/prompt/gateway/client/app) routed through manager
- hasattr capability probing for DeerMem-internal methods (no hard imports)
- MemoryConfig gains manager_class field; shared vs DeerMem-private annotated

Phase 2 — Self-contained DeerMem (steps 11-18):
- backend_config passthrough + DeerMemConfig (all DeerMem-private fields moved off MemoryConfig)
- DI: DeerMem owns storage/queue/updater/llm as instance attributes (no global singletons)
- Storage independence: core/paths.py with own root (~/.deermem or ),
  factory auto-injects deer-flow's runtime_home() as absolute base_dir (zero-config)
- LLM independence: core/llm.py via langchain init_chat_model (no create_chat_model)
- Trace independence: optional tracing_callback replaces inject_langfuse_metadata/request_trace_context
- Message processing independence: hide_from_ui default-skip + optional should_keep_hidden_message hook
- Internal imports → relative (only deer_mem.py ABC import is host-relative)
- Carrier (deer_mem.py adapter) / portable (deermem/ config+core) split
- New tests: test_deermem_self_contained + test_memory_manager_pluggable; all memory tests migrated
- Other-agent demo: samples/other_agent_demo/ + automated portability test
- config.example.yaml memory section updated to phase-2 schema

* feat(memory): port consolidation + staleness fix into self-contained DeerMem; phase-2 host hooks

Port upstream #3996 (memory consolidation) and #3993 (staleness KeyError fix)
from origin/MemoryManager into the pluggable, self-contained DeerMem structure
(backends/deermem/deermem/), adapted to the DI MemoryUpdater (config injected,
not get_memory_config globals):

- DeerMemConfig: add consolidation_enabled (opt-in, default false) /
  consolidation_min_facts / consolidation_max_groups_per_cycle /
  consolidation_max_sources
- prompt.py: factsToConsolidate JSON field + {consolidation_section} placeholder
  + CONSOLIDATION_PROMPT constant
- updater.py: _coerce_source_confidence / _select_consolidation_candidates /
  _build_consolidation_section module helpers (matching the existing
  _select_stale_candidates style); consolidation normalization in
  _normalize_memory_update_data; consolidation apply in _apply_updates (after
  max_facts trim, with apply-time guardrails mirroring staleness); staleness
  KeyError fix (f["id"] -> f.get("id") is not None) applied to both the
  staleness guardrail and the consolidation allowed_source_ids comprehension
- config.example.yaml: consolidation section under memory.backend_config
- tests/test_memory_consolidation.py: 40 DI-adapted tests (running, not skipped)
  incl. the staleness KeyError regression

Also includes in-flight phase-2 host-integration work: storage_path semantics
(any absolute/relative value = root dir) and host-default tracing_callback /
should_keep_hidden_message hooks injected into backend_config by the factory.

* feat(memory): add noop backend template and backends guide

- backends/noop/: complete drop-in template (config.py with zero deer-flow
  imports, noop_manager.py with a 6-step new-backend walkthrough in its
  docstring, commented optional fact-CRUD capabilities).
- backends/README.md: which files to touch when adding/swapping a backend,
  the 5-item backend contract, and common pitfalls.
- manager.py: generalize backend examples in comments (drop mem0-specific
  references).

* fix(frontend): guard formatTimeAgo against invalid timestamps

Return a neutral placeholder when the input date is invalid (e.g. an empty lastUpdated from a backend with no memories) instead of throwing 'Invalid time value' from date-fns.

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

* feat(memory): wire tool-driven memory mode through the MemoryManager ABC

tools.py (memory_search/add/update/delete) now calls get_memory_manager()
instead of the removed host memory module, so tool mode (memory.mode: tool)
works for any backend. DeerMem.search is implemented (case-insensitive
substring match, ranked by confidence) as a stand-in for the planned
semantic retrieval; noop.search returns [] (unchanged). Fact-CRUD tools
use getattr+callable probing -- backends lacking those ops (noop) get a
clear JSON error instead of crashing.

Tests: test_memory_tools rewired to mock the manager (handler tests) +
TestModeGating retained; test_memory_search now covers DeerMem.search;
pluggable stubs test updated (search no longer a stub).

* fix: resolve lint errors (import sorting, type annotation quotes, E402 in skipped tests)

* docs: restore explanatory comments in config.example.yaml memory section

* fix(security): port html-escape memory facts fix (#4097) to vendored DeerMem prompt.py

* fix(memory): address review + port dropped upstream memory fixes

Review blockers (vendored DeerMem):
- #4044 restore _escape_memory_for_prompt (current_memory blob in
  MEMORY_UPDATE_PROMPT) - prevents </current_memory> breakout
- #4028 html.escape staleness-section cat/content in _build_staleness_section
- #4119 add _escape_summary for injection-path summaries (Work/Personal/
  Current Focus/Recent/Earlier/Background)
- default-model silent no-op: factory injects host default chat model via a
  new host_llm slot (create_chat_model(name=None)); DeerMem prefers host_llm
  over build_llm(model). Zero-config extraction works out of the box again
- MemoryConfigResponse: fix stale docstring (backend-agnostic shape; DeerMem
  knobs live under backend_config, not top-level - restoring flat would
  re-couple the API to DeerMem). Frontend audited: does not read /memory/config
- _host_default_tracing_callback: restore langfuse assistant_id/environment
- search: push category onto the ABC signature; DeerMem filters BEFORE the
  top_k slice (was filtered client-side after slicing -> starved results)
- _do_update_memory_sync: split into wrapper+impl; bind trace_id into the
  request-trace ContextVar on the Timer/executor worker via a new
  trace_context_manager host hook (None trace_id left unbound - no fabrication)
- client.py fact-CRUD now passes user_id (was writing to the global bucket
  while get_memory reads per-user)
- _resolve_manager_class: fail-fast (raise ValueError) on an unresolved
  explicit manager_class instead of silently falling back to DeerMem (memory is
  persistent state - a wrong store is a silent data-integrity footgun)

Upstream memory fixes dropped by the host->vendored rename conflict, re-ported
to backends/deermem/deermem/core/ (+ deer_mem.py):
- #4073 queue busy-timer-spin -> _reprocess_pending flag (core/queue.py)
- #4074 null source.confidence in staleness -> _coerce_source_confidence
  (core/updater.py: _build_staleness_section + _apply_updates stale sort)
- #4075 factsToRemove is optional (drop from _REQUIRED_MEMORY_UPDATE_TOP_LEVEL_KEYS)
- #4076 null confidence in search ranking -> _coerce_source_confidence
  (deer_mem.py DeerMem.search)

host_llm + trace_context_manager are host-injected via backend_config (factory
in manager.py), keeping backends/deermem/ at exactly one `from deerflow` line
(the ABC contract) - portability test preserved.

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

* fix: resolve lint errors (F541 f-string without placeholders, E501 line too long)

* fix(memory): restore hide_from_ui clarification preservation, expose mode

Two memory-system fixes (F541/E501 lint was already fixed on this branch):

- filter_messages_for_memory: restore default preservation of well-formed
  human_input_response clarification answers (v2 regression). The
  self-containment refactor made the bare function skip ALL hide_from_ui when
  no hook was passed, but upstream preserves well-formed clarification
  responses by default (test_hide_from_ui_human_input_response_is_preserved).
  Inline a host-agnostic _is_human_clarification_response mirror of
  read_human_input_response as the default keep-decision; the host-injected
  should_keep_hidden_message hook still overrides (production path unchanged).
  Portable package stays zero `from deerflow`.

- /memory/config: expose `mode` (middleware|tool) in MemoryConfigResponse +
  the config/status endpoints + client.get_memory_config. mode is a host-
  shared, behavior-determining field missing from the response projection.
  Sync tests (mock .mode; e2e assert mode present).

- Align manager_class field docstring with fail-fast behavior.

Tests: filter/self-contained/portability (35) + memory-config (4) pass;
ruff clean.

* fix(memory): resolve ruff format failures in memory module + tests

`make lint` runs `ruff format --check` in addition to `ruff check`; 8 memory
files had pending format changes -- 7 pre-existing (deer_mem, updater, tools,
test_memory_queue/router/search/tools) + message_processing from the
hide_from_ui fix. Apply `ruff format`: whitespace/wrapping only, no logic
change. 109 memory tests pass; ruff check + format --check both clean.

* fix(memory): address PR review - legacy field migration, fact_id contract, path/docs

Address willem-bd's review on PR head bc8bf0d4 (risk:high, persistent state):

- config: auto-migrate pre-abstraction top-level memory.* DeerMem fields
  (storage_path, max_facts, debounce_seconds, model_name, token_counting,
  staleness_*, consolidation_*) into backend_config on load + warn, so an
  upgrade does NOT silently revert customized settings (was: silent
  extra='ignore' drop). model_name -> backend_config.model.model. Unknown
  top-level keys warned.
- factory: resolve a relative backend_config.storage_path against runtime_home()
  (base_dir-relative, CWD-independent) to preserve pre-abstraction semantics;
  paths.py stays portable (no runtime_home import).
- tools: memory_add uses the fact_id returned directly by create_fact instead of
  re-deriving it via content-key matching (coupled the tool to the backend's
  content normalization; could misreport a storage cap). create_fact now returns
  (memory_data, fact_id); gateway/client/tool updated. Fix terse
  {"error":"content"} -> {"error":"empty content"}.
- app.py: update stale token_counting=="char" warm-up comment to point at
  manager.warm (DeerMem.warm re-checks char and returns early).
- router: comment explaining reload_memory silent fallback vs fact 501 asymmetry
  (read-only degrade vs write fail-loud).
- CHANGELOG: document breaking changes (/memory/config + client.get_memory_config
  shape flat->backend_config; custom storage_class path moved + __init__ must
  accept config) and the legacy-field auto-migration.
- tests: add regression test pinning the per-user memory path
  ({storage_path}/users/{safe_user_id}/memory.json == host make_safe_user_id)
  across the abstraction; update create_fact mocks for (memory_data, fact_id).

Tests: 273 passed (memory suite); ruff check + format clean.

* fix(memory): address PR review - storage_path, max_facts, tracing, parsing

Six review findings (willem-bd), each verified against upstream:

- storage_path semantics (file -> root dir): migration drops file-style
  (.json) legacy values with a warning; factory raises if storage_path
  resolves to an existing file (avoid silent NotADirectoryError write
  failure). CHANGELOG + config.example.yaml comment updated.
- create_memory_fact enforces max_facts again (via _trim_facts_to_max) and
  returns (memory, None) when the cap evicts the new fact; memory_add tool
  reports "not stored", client raises ValueError, POST /memory/facts -> 409.
- max_facts trim uses _coerce_source_confidence (was raw f.get("confidence",
  0) -> TypeError on non-float imported/legacy confidence, swallowed as
  silent update failure).
- memory-tracing assistant_id restored to "memory_agent" (was "lead-agent"
  copy-paste; matches upstream + DeerMem run_name).
- _is_human_clarification_response cross-checked against
  read_human_input_response (drift guard test).
- empty-string legacy values skipped silently in migration (narrow fix, not
  broad "if not value" which would skip explicit bool False).

8 new regression tests. make lint + 406 memory tests pass.

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

* fix(memory): address internal review - storage fail-fast, build_llm degrade, config warn, noop template

Addresses 4 findings from the PR #4122 internal supplemental review
(parallel to willem-bd's review, no overlap):

- create_storage fail-fast: a misspelled/unimportable storage_class now
  raises ValueError instead of silently falling back to FileMemoryStorage.
  Memory is persistent state, so a wrong store is a data-integrity footgun;
  mirrors the existing manager_class resolution policy. (storage.py)

- noop template create_fact signature: the commented template used
  keyword-only `content` and returned a bare dict, while DeerMem's actual
  create_fact takes positional `content` and returns tuple[dict, str|None]
  (the memory_add tool passes content positionally; gateway/client/tools all
  tuple-unpack). A backend copied from the template would 500 on fact-CRUD.
  Template fixed; delete_fact/update_fact templates left (callers compatible).
  (noop_manager.py)

- build_llm graceful degrade: wrap init_chat_model in try/except, degrade to
  None + WARNING on failure (mirroring _host_default_llm) so a misconfigured
  explicit model does not crash app startup -- non-LLM memory ops still work
  and an update raises at runtime with the error logged. (llm.py)

- from_backend_config unknown-key warning: log a WARNING for unknown
  backend_config keys (mirrors the host layer's load_memory_config_from_dict)
  so a typo like `storage_pat` does not silently fall back to the default and
  write memory to an unintended location. (config.py)

Tests: rewrote 3 create_storage fallback tests to expect ValueError; added 4
tests (build_llm zero-config/degrade, from_backend_config warn/silent).
make lint green; full memory suite passes.

fix(agents): require config.yaml in update_agent's legacy-agent guard (#4166)
update_agent (the harness tool) and PUT /api/agents/{name} (the same
operation over HTTP) share an identical guard meant to block updates to
an agent that only exists in the legacy shared layout. The guard checked
bare directory existence:

    if not agent_dir.exists() and paths.agent_dir(name).exists():

When memory is enabled, the first time a user chats with a legacy shared
agent, the memory writer creates a per-user directory containing only
memory.json (no config.yaml). agent_dir.exists() is then true, so the
guard never fires: the tool falls through to load_agent_config, which
resolves through to the legacy shared config via the already-hardened
resolve_agent_dir, and silently writes a brand-new config.yaml/SOUL.md
into the memory-only directory. That forks the agent for just this user;
every other user keeps reading the original shared config forever, with
no error or warning.

resolve_agent_dir itself was already hardened against exactly this
failure mode: it requires config.yaml to exist, not just the directory.
Mirror that condition at both call sites here.

fix(channels): drop redundant GitHub review-comment webhook fan-out (#4131)
* fix(github): drop redundant pull_request_review_comment fan-out noise

GitHub fires one pull_request_review_comment webhook per inline comment
attached to a pull_request_review submission, in addition to the single
pull_request_review event for the review itself. A bot reviewer like
CodeRabbit commonly leaves 20-30 inline comments per review, flooding
the webhook with near-duplicate deliveries that carry nothing an agent
doesn't already have -- it fetches every inline comment itself via
`gh api` when it processes the parent pull_request_review event.

Filter these out in fanout_event() before the registry lookup / per-
agent loop, since the redundancy is a property of the event itself, not
of any specific agent binding. A companion comment is identified by
pull_request_review_id being set (it belongs to a review) and
in_reply_to_id being absent (it is not itself a reply within an
existing thread -- that case is a genuine new interaction and must
still fire).

* fix(channels): scope review-comment suppression to bindings that also see the review

The redundant pull_request_review_comment filter suppressed every
companion comment unconditionally, before the registry lookup even ran.
That premise only holds for a binding that also subscribes to
pull_request_review on the same repo -- events are opt-in per binding,
so a binding registered for pull_request_review_comment alone never
receives the parent review event and the companion comments were its
only delivery of the review's inline content. Suppressing those too was
a silent, total loss for that binding, not noise reduction.

Move the check into the per-agent loop so it only suppresses a matched
binding's companion comment when that same binding also has an active
pull_request_review trigger on this repo, reusing the existing registry
lookup rather than re-walking bindings by hand. Bindings subscribed to
pull_request_review_comment alone now always fire, matching the
opt-in-per-binding contract documented in triggers.py.

* fix(channels): close require_mention gap in review-comment redundancy gate

willem-bd's second review round found that the per-binding redundancy gate
(commit b3791b33) treated a binding as "covered" purely by checking whether
it also registers a `pull_request_review` trigger on this repo, ignoring
whether that trigger itself requires a mention. A `pull_request_review_comment`
payload never carries the paired review's own top-level body, so there is no
way to verify from a comment delivery whether that trigger's own
`require_mention` check would actually pass. A human `@mention` living only
in one inline comment (not the review summary) could therefore be lost
twice: the review event filtered out by its own `no_mention` gate, and the
one inline comment that carries the mention dropped here as "redundant" --
the same silent-loss shape as the original bug, through a narrower path.

The gate now also requires the paired `pull_request_review` trigger's
resolved `require_mention` to be false before treating it as coverage,
trading a small amount of residual redundancy (an extra companion delivery
when the review would have fired anyway) for zero silent loss.

While in the same code, also addressed two smaller review notes:
- The redundant-comment skip reason now prefers the companion's own trigger
  verdict when that verdict is also a skip (e.g. its own `require_mention`
  independently fails), instead of always reporting the generic
  `redundant_review_comment` label.
- `_pr_review_prompt` now tells the agent to fetch a review's inline
  comments via `gh api .../reviews/{id}/comments` -- the redundancy gate's
  suppression is only genuinely redundant if the agent actually recovers
  that content from the parent review event, and nothing previously told it
  to (zhfeng's review).

Tests: reproduces willem-bd's exact scenario (dual-subscribed binding,
require_mention on the review trigger, mention present only in the inline
comment) and confirms it fails on the prior code and passes with the fix;
adds a multi-agent-independence test and a skip-reason-precedence test;
adds prompt tests locking the new fetch-hint text and its missing-id guard.
Fail-before/pass-after verified via patch-file revert (not stash, to avoid
colliding with sibling worktrees).

fix(checkpoint): persist run duration in checkpoints for history reads (#4118)
* fix: persist run duration in checkpoints for history reads

* fix(checkpoint): harden run duration persistence

* fix(checkpoint): persist run durations in metadata

* fix(checkpoint): address review findings for run duration persistence

- Add valid_duration_entry() shared validation helper (worker.py)
- Rename _persist_run_durations -> persist_run_durations as public API
- Import public persist_run_durations and valid_duration_entry in threads.py
- Use BackgroundTasks for lazy backfill write to avoid blocking history reads
- Add TODO about O(runs) growth of run_durations in checkpoint metadata
- Document REGENERATE_HISTORY_RAW_SCAN_LIMIT doubling assumption

* fix(checkpoint): replace pruning TODO with justification

Accumulated run_durations overhead (~50 bytes/run_id) is negligible compared
to messages channel blobs; no pruning strategy is needed.

feat(trace): add agent observability with Monocle (#4024)
* Add Monocle tracing

Enable Monocle (OpenTelemetry tracing for LLM apps) with one setup call plus the monocle_apptrace dependency. setup_monocle_telemetry auto-instruments the frameworks already in use and writes traces to .monocle/. Additive; no changes to application logic.

* Config-gate Monocle telemetry in the Gateway lifespan

Addresses review on #4024: moves setup_monocle_telemetry out of agents/__init__ import time into the Gateway lifespan, gated by MonocleTracingConfig (MONOCLE_TRACING env, default off). Warns on the Langfuse/global-OTel-provider conflict and relies on monocle_apptrace's own duplicate-setup guard and existing-provider attach. Pins monocle_apptrace>=0.8.8 (+ uv.lock), adds .monocle/ to .gitignore, adds tests (default-off / toggle-on / no import-time setup), and documents exporters, Okahu, and the VS Code viewer in README, config.example.yaml, and backend/AGENTS.md.

* Clarify Monocle/Langfuse single-provider guidance

Make the docstring, warning, and AGENTS.md consistent with the README: only one library can own the global OpenTelemetry provider; Monocle initializes at startup before Langfuse's per-run handler, so enabling both drops Langfuse's spans — enable one OTel tracer (LangSmith, a callback, coexists fine).

* Address review: optional extra, exporter validation, off-box warning, tests

Responds to the second review round.

- Make monocle_apptrace an optional extra (deerflow-harness[monocle], re-exposed
  as deer-flow[monocle]) following the boxlite/tui precedent, so a default
  install no longer pulls the OpenTelemetry stack. It stays pinned in the dev
  group for the tracing tests, and enabling MONOCLE_TRACING without the extra
  raises a clear install error.
- Warn loudly at startup whenever any exporter other than `file` is configured,
  since those move prompts, tool inputs/outputs, and completions beyond the
  local .monocle/ directory.
- Validate MONOCLE_EXPORTERS against the known exporter names and require
  OKAHU_API_KEY when okahu is selected, mirroring the Langfuse pattern.
  Validation runs from Monocle's own init (not validate_enabled) so a config
  typo can never fail agent runs; errors surface at Gateway startup instead.
- Grow the tests from 5 to 13: caplog coverage for the Langfuse-conflict and
  off-box warnings, exporter validation cases, a stronger import-time
  regression that asserts the global TracerProvider is not replaced, and a
  subprocess double-invoke test exercising the real check_duplicate_setup.
- Docs: config.example.yaml block retitled to a dedicated tracing header;
  README documents the [monocle] install and scopes tracing to Gateway runs.

* docs: align Monocle README section with the other tracing providers

Lead with what Monocle is and captures, drop the install step (the dev
group already ships monocle_apptrace via uv sync; unusual installs get
the RuntimeError), and point the missing-package error at the repo-native
command (uv sync --extra monocle / deerflow-harness[monocle]).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Address review: verified Langfuse coexistence, lifespan test, scope docs

Responds to the third review round.

The Langfuse conflict claim was wrong, verified empirically against langfuse
4.5.1 in both init orders: whichever library initializes second reuses the
existing global TracerProvider and attaches its own span processor, so neither
side loses spans. Dropped the warning and its tests, corrected the README,
AGENTS.md, and config.example.yaml statements, and pinned the verified behavior
with test_coexists_with_langfuse (real monocle + real langfuse in a subprocess,
no mocks). One honest caveat documented: both processors see all spans, so
Monocle's exporters also capture Langfuse's spans when both are enabled.

Also from the review:
- Document the Gateway-only scope in AGENTS.md: the lifespan is the sole call
  site, so the embedded DeerFlowClient and TUI are not instrumented; embedded
  users call setup_monocle_tracing_if_enabled() themselves.
- Add test_gateway_lifespan_initializes_monocle pinning the lifespan wiring.
- Comment why MonocleTracingConfig.is_configured is intentionally coarser than
  LangSmith/Langfuse (composite validation lives in validate() at startup).
- Note that monocle_exporters_list takes the comma-separated string as-is.
- Module-level importorskip("monocle_apptrace") so minimal installs collect
  the test module cleanly.

* docs: reword Monocle intro sentence

* fix(tests): run the import-time regression in a subprocess

test_no_import_time_setup deleted deerflow.agents* from sys.modules and
re-imported to force __init__ to re-execute. The re-import creates new module
objects, and restoring the old sys.modules entries afterwards leaves the parent
package's attribute bindings pointing at the new ones, so any later test that
resolves a deerflow.agents.* dotted path (monkeypatch.setattr in
test_summarization_middleware, test_thread_data_middleware, and others) failed
with "module 'deerflow.agents' has no attribute ...".

Run the check in a subprocess instead: the import is genuinely fresh, the
assertion is stronger (the provider must still be the SDK-less proxy, proving
nothing was installed at any point), and no module identity leaks into the
rest of the suite.

* Address review: console warning scope, embedded hint, honest naming, doc alignment

Responds to the post-approval review round:

- Scope the off-box exporter warning to the remote exporters (okahu, s3,
  blob, gcs): console writes to local stdout and no longer trips it.
  config.example.yaml's data-handling note now distinguishes file /
  console / remote likewise.
- Rename MonocleTracingConfig.is_configured to is_enabled so the boolean
  reads as what it checks; the exporter-dependent credential check stays
  in validate(), run at Gateway startup.
- Hint on the embedded path: build_tracing_callbacks() logs a debug line
  when MONOCLE_TRACING is set but setup never ran in this process, so
  embedded DeerFlowClient/TUI users are not left with silent no-op
  tracing. Backed by a process-global setup flag.
- Re-export setup_monocle_tracing_if_enabled from deerflow.tracing,
  matching the package convention.
- Note the deliberate fail-open-at-startup contrast with
  LangSmith/Langfuse in the lifespan, and the OTel SDK-internals
  dependency in the coexistence test.
- Test hygiene: clear MONOCLE_* env in the tracing config/factory
  fixtures; reset the setup flag in the monocle test fixture; reword the
  README Langfuse-spans claim as the shared-provider inference it is.
- Document that .monocle/ trace files are never rotated or cleaned up.

* fix(tests): pin the factory logger level in the embedded-hint tests

configure_logging() from earlier tests in the full suite pins an explicit
INFO level on the logger hierarchy, so a root-level caplog.at_level(DEBUG)
never sees the factory's debug hint. Scope caplog to
deerflow.tracing.factory so the test is independent of suite ordering.

* Address review: co-export disclosure, lifespan failure test, exporter parse dedup

- Off-box warning now notes that Langfuse's spans are exported too when
  both providers are enabled and share the global OTel provider; pinned
  both ways by tests.
- Pin the lifespan fail-open contract: a raising Monocle setup is logged
  and the Gateway keeps serving (pragma dropped now that the path is
  exercised). README notes a config error is reported at startup and
  tracing stays off until restart.
- Hoist exporter parsing into MonocleTracingConfig.exporter_list so
  validate() and the off-box warning cannot diverge, and note the
  upstream coupling on the exporter allow-list.
- Reduce config.example.yaml's Monocle block to a pointer; the capture,
  retention, and data-handling detail lives in README's Monocle section.

fix(runs): cancel degrades to lease takeover for multi-worker (#4064)
* fix(runs): cancel degrades to lease takeover for multi-worker

Work item 4 of the multi-worker ownership epic
(https://github.com/bytedance/deer-flow/issues/3948).

Problem: POST /runs/{run_id}/cancel landing on a non-owning worker
returns 409 — the cancel button silently fails under GATEWAY_WORKERS>1
with no sticky routing. cancel() required the current worker to hold
the in-memory task/abort_event, which any non-owner pod cannot satisfy.

Changes:
- RunManager.cancel() returns CancelOutcome enum (cancelled /
  taken_over / lease_valid_elsewhere / not_active_locally /
  not_cancellable / unknown) instead of bool, so the router can map
  each outcome to the right HTTP response.
- New store primitive claim_for_takeover(): a single atomic
  conditional UPDATE that marks a run as error only when
  status IN (pending, running) AND (lease IS NULL OR
  lease < now - grace). Closes the stale-read / concurrent-heartbeat
  race — if the owner renews between our read and write, the UPDATE
  matches 0 rows and we surface lease_valid_elsewhere.
- HTTP cancel + stream-join endpoints route on CancelOutcome:
  cancelled -> 202 (or 204 with wait=true); taken_over -> 202
  immediately (no SSE streaming — the run is terminal on another
  worker, streaming would hang); lease_valid_elsewhere -> 409 +
  Retry-After header computed from lease_expires_at + grace_seconds.
- RunManager.grace_seconds exposed as a public property; the router
  no longer reaches into _run_ownership_config.
- _is_lease_expired extracted to a module-level function, shared by
  RunManager.cancel() and MemoryRunStore.claim_for_takeover().
- GATEWAY_WORKERS=1 + heartbeat_enabled=false is zero-regression:
  the non-local path short-circuits to not_active_locally, preserving
  the original 409 behaviour the existing tests pin.

Tests: 12 new (5 store primitive + 4 cancel-takeover unit + 3 HTTP
including a regression guard verifying POST /stream?action=interrupt
on a dead-owner run returns 202 instead of hanging on SSE).
244 directly-related tests pass; 36/36 blocking-IO gate pass.

* fix(runs): guard update_status and self-terminate on takeover

Two defenses close a split-brain window where the original owner
could overwrite a peer's takeover status:

- update_status (SQL + memory store) now guards on
  status IN ('pending','running'). When takeover already set
  the row to 'error', the owner's final status write matches
  0 rows and is dropped.

- _persist_status: when update_status returns False, check
  whether the row exists before attempting recovery via put().
  If the row exists (takeover by another worker), skip recovery
  instead of blindly upserting over the takeover.

- Heartbeat _renew_leases: when update_lease returns False
  (row no longer pending/running or owner changed), cancel the
  local task so wasted CPU is bounded to the next heartbeat
  tick (~10s) instead of the full task lifetime.

Also fix three reviewer feedback items:

- Re-fetch the store row when cancel() returns
  lease_valid_elsewhere, so Retry-After uses the owner's
  freshly-renewed lease instead of a stale value from
  request start.

- Fallback 'unknown' in takeover error message when
  owner_worker_id is NULL (pre-ownership data).

- Remove dead else-10 branch from grace_seconds property
  (unreachable — all callers are downstream of the
  heartbeat_enabled guard).

* test(runs): pin split-brain defences from update_status guard + heartbeat

Three tests lock down the takeover authoritativeness so a
late-running owner cannot overwrite a peer's claim:

- update_status must reject writes when the store row is already
  terminal (taken over by another worker).
- _persist_status must skip row-recovery via put() when the row
  exists but has been taken over.
- Heartbeat _renew_leases must cancel the local task when
  update_lease returns False (row claimed by another worker).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix(runs): precise outcome + log when local cancel loses to peer takeover

Two reviewer precision nits on the split-brain defence:

- _persist_status: branch the skip-reason log on existing["status"].
  error → WARNING "peer takeover" (anomalous); interrupted/success →
  INFO "local cancel/completion race" (expected when user hits stop
  as the run finishes). Stops noisy false-positive takeover warnings
  in operator logs.

- cancel() local path: when _persist_status returns False, re-check
  the store. If a peer's claim_for_takeover flipped the row to error
  between our in-memory cancel and the guarded update_status, surface
  taken_over instead of cancelled so the client sees a status
  consistent with the store.

Test: test_cancel_returns_taken_over_when_peer_claims_during_local_cancel
pins the race outcome.

* fix(runs): widen update_status guard, de-duplicate lease helpers, add coverage

Round 3 of reviewer feedback:

- Widen update_status guard to status IN ('pending','running','interrupted').
  The original guard blocked interrupted→error (the rollback finalize path),
  losing the "Rolled back by user" message. interrupted is now permitted
  while error/success stay locked — takeover protection unchanged.

- claim_for_takeover False now re-reads the store row to distinguish causes:
  owner renewed lease → lease_valid_elsewhere; row went terminal →
  not_cancellable; another worker already took it over → taken_over.

- Extract _raise_lease_valid_elsewhere() helper to de-duplicate the
  409+Retry-After block shared across cancel_run and stream_existing_run.

- Extract _lease_expired_or_null() in persistence/run/sql.py to
  de-duplicate the lease-expiry SQL WHERE clause shared by
  claim_for_takeover and list_inflight_with_expired_lease.

- 11 new tests: 5 SQL-layer claim_for_takeover (expired/valid/NULL/
  terminal/nonexistent), 3 _compute_retry_after unit (NULL/unparseable/
  normal), 2 claim re-read precision (terminal/takeover), 1 stream
  endpoint 409+Retry-After.

Not addressed (non-blocking, reviewer agreed):
- The 2–3 store.gets in the takeover cold path: optimizing the API to
  accept a pre-fetched record would couple the router to the manager
  more tightly than justified by the perf gain.
- The lease-expiry inline loop in MemoryRunStore.list_inflight_with_-
  expired_lease pre-computes cutoff once for all rows; switching to the
  shared _is_lease_expired helper would recompute datetime.now() per row
  with no real benefit.

260 related tests pass; 36/36 blocking-IO gate pass; ruff clean.

* fix(runs): de-duplicate lease-expiry helper, restore defensive fallback

Address final round of review feedback:

- Extract is_lease_expired to deerflow.utils.time (no _ prefix, public
  utility). Manager and MemoryRunStore now import from the same place
  instead of the store reaching backward into the manager for a private
  function.

- Restore defensive else-10 fallback in grace_seconds property (removed
  in an earlier round). The guard is unreachable for current callers but
  protects future ones from AttributeError.

- Comment the transient in-memory interrupted vs store error state when
  a local cancel is superseded by a peer takeover.

- Comment the max(1, ...) floor in _compute_retry_after — the floor is
  a lower bound, not a poll interval; clients should apply jitter.

Fix require_mention gating on whitespace-only bot_login/mention_login (#4055)
github.bot_login and trigger.mention_login were read raw in the
require_mention precedence chain, so a whitespace-only value (e.g. "   ")
never fell through to the working fallback the chain documents -
Python truthiness lets "   " win an `or` chain over agent.name or the
operator default. The third link (channels.github.default_mention_login)
was already correctly normalized and pinned by
test_operator_default_blank_string_treated_as_none; this closes the gap
for the other two by normalizing GitHubTriggerConfig.mention_login and
GitHubAgentConfig.bot_login once, at the config layer, via a
field_validator mirroring the pattern already used elsewhere in the
config package.

fix(channels): validate channel provider before resolving its config (#4100)
`_provider_config` resolved a request-supplied provider name with an
unallowlisted `getattr(config, provider, None)`. `ChannelConnectionsConfig`
carries non-provider attributes -- the `enabled` and `require_bound_identity`
bool fields plus the `provider_status` method -- so a name matching one of
them returned that attribute instead of falling through to the intended 404.
Callers (e.g. `POST /api/channels/{provider}/connect`, reachable by any
authenticated user) then dereferenced the bool/method as a provider config,
crashing with `AttributeError` -> HTTP 500.

Validate `provider` against the `_PROVIDER_META` allowlist before the lookup,
matching how `_credential_fields` / `_connect_instruction` / `_connect_url`
already gate provider names, so unknown providers get a clean 404.

Add a parametrized router regression test covering `enabled`,
`require_bound_identity`, `provider_status`, and an unknown name.

fix(artifacts): honor trusted owner-user-id header (#3982)
* fix(artifacts): honor trusted owner-user-id header

The artifact endpoint resolved paths only via the effective user, so a
trusted internal caller acting on behalf of an owner (carrying
X-DeerFlow-Owner-User-Id) read the synthetic internal user's storage and
404'd on files the owner's run had written.

Resolve the owner via get_trusted_internal_owner_user_id and pass it
through resolve_thread_virtual_path (now accepting an optional user_id),
matching the memory and threads routers. Browser/API callers send no
such header and fall back to the effective user, so their behavior is
unchanged.

* fix(artifacts): normalize trusted owner id through make_safe_user_id

The owner-user-id header carries the raw platform owner id, while runs
store files under the make_safe_user_id bucket. Resolve artifacts with
the normalized id, mirroring the memory router.

fix(runs): close multi-worker ownership gaps in run atomicity (#3948) (#4003)
* feat(runs): cross-process run ownership with lease + reconciliation (#3948)

Implements work items 2 and 3 of the multi-worker P0 plan
(docs/multi_worker.md). Work item 1 (Postgres startup gate, #3960)
already landed; this PR makes run creation race-safe across worker
processes and lets Postgres deployments recover orphaned inflight runs
from crashed workers without mis-marking live runs as orphans.

Work item 2 — cross-process atomic create_or_reject

- Alembic revision 0004_run_ownership adds runs.owner_worker_id,
  runs.lease_expires_at, idx_runs_lease, and a partial unique index
  uq_runs_thread_active (one pending/running run per thread). The
  index is declared on RunRow.__table_args__ with sqlite_where +
  postgresql_where (mirroring uq_channel_connection_active_identity)
  so the empty-DB bootstrap path — which runs Base.metadata.create_all
  + alembic stamp head without executing any revision's upgrade() —
  also lands it on fresh deployments. Migration 0004 additionally
  creates it idempotently for legacy/versioned upgrades.
- RunRepository.create_run_atomic is the new atomic primitive:
  - reject: INSERT directly; the partial unique index catches
    duplicate active runs; the manager surfaces the result as
    ConflictError.
  - interrupt/rollback: SELECT FOR UPDATE the conflicting rows,
    skip rows whose lease is still valid AND owned by another live
    worker (raise ConflictError — the INSERT would have failed on
    the index anyway, and a retry loop cannot make progress),
    cancel the rest in the same transaction, then INSERT the new
    row. Rows owned by this worker are interruptible regardless of
    lease state.
- RunManager.create_or_reject dispatches to the store under the
  existing local lock; same-worker in-memory cancellation runs after
  the store commit succeeds. MemoryRunStore mirrors the same
  semantics for tests and database.backend=memory.

Work item 3 — lease heartbeat + Postgres reconciliation

- RunOwnershipConfig (lease_seconds=30, grace_seconds=10,
  heartbeat_enabled=false by default), registered as startup-only in
  reload_boundary.STARTUP_ONLY_FIELDS because the heartbeat background
  task is created once in langgraph_runtime() and is not rebuilt on
  config.yaml edits.
- When heartbeat_enabled, each worker renewes leases on its own
  active runs with interval = lease_seconds / 3. The loop is bounded
  and stop-event-cancellable so shutdown is prompt.
- reconcile_orphaned_inflight_runs now runs on every backend — the
  sqlite-only gate in app/gateway/deps.py is dropped in the same
  commit so there is no window where Postgres would mis-mark live
  Worker A runs as orphans. Reconciliation errors only runs whose
  lease is NULL (legacy pre-ownership rows) or older than
  grace_seconds. In single-worker mode (heartbeat off, NULL leases)
  all inflight rows reclaim immediately, preserving the pre-ownership
  recovery latency.
- Heartbeat starts AFTER startup reconciliation and stops BEFORE the
  in-flight run drain on shutdown so the two cannot race.

GATEWAY_WORKERS=1 with heartbeat_enabled=false keeps current behavior.

Verified: 170 related tests + full backend suite (minus Docker-gated
live tests) green; ruff check + ruff format clean.

* fix(runs): tighten unique-violation handling and document clock-sync budget

Three follow-up fixes to the cross-process run ownership work in #3948,
surfacing during review.

1. _is_unique_violation: detect by driver-native signal, not message text

   The previous substring heuristic ("unique" + "violat", or "duplicate")
   missed SQLite's actual phrasing "UNIQUE constraint failed: <table>.<index>"
   — SQLite says "failed", not "violates", and never "duplicate". On SQLite
   the detector returned False, the reject path re-raised the raw
   IntegrityError, and clients saw HTTP 500 instead of ConflictError 409.
   The conversion is the load-bearing piece of the "store is source of
   truth" design but was untested — every atomic test used MemoryRunStore,
   which raises ConflictError directly and never reached this branch.

   Now prefers driver-native signals: psycopg pgcode/sqlcode "23505" and
   sqlite3 sqlite_errorcode SQLITE_CONSTRAINT_UNIQUE (reachable through
   SQLAlchemy IntegrityError.orig). Message matching stays as a fallback
   with SQLite's exact "unique constraint failed" phrase added.

2. interrupt/rollback: convert exhausted-retry IntegrityError to ConflictError

   The reject branch converts unique violations to ConflictError. The
   interrupt/rollback retry loop did not — on the 3rd attempt it re-raised
   the raw IntegrityError, leaking HTTP 500 for the same race condition
   that reject surfaces as 409. Symmetric conversion added after the loop;
   callers now see a consistent ConflictError regardless of strategy.

3. Document clock-sync requirement for multi-worker lease reconciliation

   reconcile_orphaned_inflight_runs compares another worker's UTC
   lease_expires_at against this worker's datetime.now(UTC). The only skew
   budget is grace_seconds (default 10s) — worst case, with the owning
   worker's heartbeat just about to fire, a peer whose clock is more than
   ~grace_seconds ahead can mis-reclaim a still-live run as an orphan.

   Documented in RunOwnershipConfig's docstring (with the math) and in
   config.example.yaml (with operational guidance), so operators in
   NTP-poor environments know to raise grace_seconds. Default unchanged:
   10s is reasonable for NTP-synced K8s/cloud, and bumping it would slow
   recovery of genuinely dead workers (lease_seconds + grace_seconds from
   last heartbeat to reclaim).

Tests:
- test_create_run_atomic_reject_propagates_conflict_on_unique_violation:
  end-to-end against a real SQLite-backed RunRepository, pre-inserts an
  active run, asserts reject-strategy create surfaces as ConflictError
  rather than raw IntegrityError.
- test_is_unique_violation_detects_real_sqlite_integrity_error: unit test
  for the detector against a real SQLite-raised IntegrityError; asserts
  driver-level sqlite_errorcode is SQLITE_CONSTRAINT_UNIQUE.
- test_interrupt_exhausted_retries_surface_as_conflict_error: pins the
  symmetric 409 behavior after the retry loop exhausts.

Verified: ruff check + ruff format clean; multi-worker + run_repository
+ owner_isolation + reload_boundary suites green.

* fix(runs): close multi-worker ownership gaps in lease heartbeat and unique-violation detection

Five code-review fixes from docs/multi_worker.md:

1. Drop unused ``claim_inflight_runs`` primitive — no caller anywhere.
   ``create_run_atomic`` does its own inline claim (SELECT FOR UPDATE +
   cancel) inside the INSERT transaction; a separate claim primitive
   would split that into two transactions and open a claim→INSERT race.
   Removes ~40 lines across base.py / memory.py / sql.py plus the
   unused ``now_iso`` parameter, freeing future RunStore implementations
   from providing it.

2. Broaden ``_renew_leases`` filter to renew pending/running runs owned
   by this worker even when ``record.task is None``. The previous
   ``task is not None`` requirement skipped the brief window between
   ``create_run_atomic`` inserting the row and the worker spawning the
   agent task; under event-loop load that window can approach
   ``lease_seconds``, after which peer reconciliation marks the run
   ``error`` (visible) or a peer's ``create_or_reject("interrupt")``
   silently kills the queued run. Filter now:
   ``task is None or not task.done()``.

3. Document the unsynchronised ``record.lease_expires_at = new_expiry``
   write. ``lease_expires_at`` is the only field on an existing record
   this path mutates; ``set_status`` / ``_persist_status`` touch other
   fields, so there is no concurrent writer to race against. Re-acquiring
   ``self._lock`` would serialise unrelated run mutations for no gain.

4. Gate ``_is_unique_violation`` message fallbacks on
   ``isinstance(current, (SAIntegrityError, sqlite3.IntegrityError))``.
   The driver-code path (pgcode/sqlite_errorcode) remains load-bearing;
   substring fallbacks are now belt-and-suspenders only for cases where
   the driver attribute isn't reachable through the cause chain. Without
   the gate, any application exception whose ``str()`` happens to contain
   "duplicate key" / "unique" + "violat" (CHECK constraint, validation
   error) would silently surface as HTTP 409 instead of 500.

5. Route ``update_lease`` through ``_call_store_with_retry`` for
   consistency with every other store call, and wrap
   ``await self._renew_leases()`` in ``_heartbeat_loop`` with
   ``except Exception: logger.warning(...)``. Previously a transient
   error from the snapshot path or an unexpected exception would kill
   the heartbeat task silently — after which no lease is ever renewed
   again and every active run eventually looks orphaned.
   ``except Exception`` lets ``CancelledError`` (BaseException since
   3.8) propagate so shutdown cancellation still works.

Regression tests:
- ``test_heartbeat_renews_pending_run_before_task_is_spawned``
- ``test_is_unique_violation_does_not_misclassify_application_exception``

* fix(runs): harden multi-worker migration, memory atomicity, and tz-naive lease comparison

Three follow-up fixes to the multi-worker run ownership work:

- migration 0004 dedupe pass: cancel superseded duplicate active rows per
  thread before creating the partial UNIQUE index ``uq_runs_thread_active``
  so dirty DBs (Postgres deployments that had reconciliation skipped by the
  old sqlite-only gate, or any env that ran GATEWAY_WORKERS>1 before this PR)
  do not abort the alembic upgrade and block gateway startup. Keeps the
  newest active row per thread, marks the rest as error with an explanatory
  message.

- MemoryRunStore.create_run_atomic interrupt/rollback path: split the single-
  pass loop into two passes (collect candidates, validate, then mutate) so a
  ConflictError raised on a later candidate does not leave earlier candidates
  half-interrupted. Mirrors the SQL store's transactional rollback semantics;
  the entire test_multi_worker_run_ownership.py suite runs against memory so
  this divergence was giving false confidence.

- RunRepository.create_run_atomic interrupt path: coerce tz-naive
  ``row.lease_expires_at`` to UTC before comparing against the aware
  ``cutoff``. SQLite drops tzinfo on read despite ``DateTime(timezone=True)``
  (this file's own comment acknowledges it), so the Python-side comparison
  raised ``TypeError: can't compare offset-naive and offset-aware datetimes``
  whenever heartbeat was enabled on SQLite and a lease was non-NULL. Defaults
  (heartbeat off -> leases always NULL) masked it, but there was no guard
  against the combination. Follows the existing "naive is UTC" convention
  from ``coerce_iso``.

Each fix ships with a regression test pinning the behavior.

* fix(runs): enforce heartbeat for multi-worker, fix memory-store datetime comparison, lazy-import ConflictError in store layer

Three fixes from code review:

1. Extend the startup gate (GATEWAY_WORKERS>1) to also require
   run_ownership.heartbeat_enabled=true. Without heartbeat every run has
   a NULL lease, so reconciliation treats all inflight rows as orphans
   and Worker B would kill Worker A's live runs on every rolling update
   or scale-up.

2. Fix MemoryRunStore.list_inflight_with_expired_lease to parse
   created_at as datetime instead of ISO string lexical comparison,
   and handle tz-naive lease values uniformly with the SQL store.

3. Store layer (sql.py, memory.py) now lazy-imports ConflictError
   inside create_run_atomic instead of importing from the higher
   RunManager layer at module level.

* fix(runs): add owner check to update_lease, document create() assumption, restore deleted comment

- update_lease (SQL + memory) now requires owner_worker_id match in WHERE
  clause so the primitive is safe by construction against misuse
- create() docstring notes it bypasses atomic create_run_atomic and
  assumes no active run exists for the thread
- restore explanatory comment in MemoryRunStore.aggregate_tokens_by_thread
  that was dropped in an earlier commit

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix(runs): add psycopg3 sqlstate detection and periodic orphan reconciliation

- _is_unique_violation now checks sqlstate attribute (psycopg3 uses this
  instead of pgcode). On Postgres, the only supported multi-worker backend,
  detection was falling through to the message-substring fallback.
- _heartbeat_loop now runs reconcile_orphaned_inflight_runs every 3rd
  cycle (every lease_seconds) to catch orphans whose lease expires between
  pod restarts. Single-worker deployments are unaffected (heartbeat off).

feat: add composer input polishing (#3986)
* 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.

feat(skills): Add native SkillScan phase 1 for skills (#3033)
* Add phase 1 skill static scanning

* Rework SkillScan phase 1 as native scanner

* refactor(skillscan): align phase 1 with trimmed RFC contract

- SecurityFinding: 7 fields (rule_id, severity, file, line, message,
  remediation, evidence); category/analyzer derive from the rule_id
  prefix, confidence/column/fingerprint/metadata removed
- scan_archive_preflight()/scan_skill_dir() are pure functions: no
  ScanContext, no policy schema; CRITICAL-blocks is a code constant and
  skill_scan.enabled is applied by enforce_static_scan()/callers
- secret-* evidence is redacted before findings leave the scanner
- de-dup keys on (rule_id, file, line) so repeated occurrences keep
  distinct locations for agent self-correction
- cloud-metadata detection consolidated into network-cloud-metadata
- nested zip members get a one-level stdlib magic-byte peek; an
  executable member escalates package-nested-archive to CRITICAL
- install metadata sidecar removed (Phase 7 decides if it is needed)
- rule specs moved next to their analyzers; skillscan/rules/ removed
- tests updated + new anchors: redaction, dedup lines, nested-zip
  escalation, single cloud-metadata rule, bundled-skill zero-CRITICAL

* fix(skillscan): tighten reverse-shell/secret/archive scan rules from review

Address PR #3033 review feedback on the native SkillScan analyzers:

- Reverse-shell false positives: split shell detection by signal strength
  (/dev/tcp/, nc -e stay CRITICAL; bash -i, mkfifo -> new HIGH
  shell-reverse-shell-heuristic, warn->LLM). The Python check is now
  AST-anchored on real socket.socket/os.dup2/subprocess call sites instead
  of raw-text substring matching, so prose/docstrings no longer hard-block.
- Secret evidence: _redact_secret_evidence returns [redacted] with no secret
  bytes (was value[:6], which leaked 2 real token bytes past the prefix).
- Archive DoS: cap outer archive member count (_MAX_ARCHIVE_MEMBERS=4096);
  scan_archive_preflight early-aborts with a package-too-many-members CRITICAL
  finding (routes through the existing blocked->400 fail-closed path).
- shell-destructive-command: broaden the rm -rf matcher to sensitive system
  roots (/home, /usr, /*, --no-preserve-root /) while leaving safe subpaths
  unflagged.
- Dead code: collapse _decode_text_for_analysis to a single decode path and
  drop the unused _TEXT_SUFFIXES set and _has_text_shebang helper.
- local_skill_storage: document why the host_path branch keeps app_config
  possibly-None (lazy kill-switch resolution; avoids eager get_app_config in
  config-free environments such as CI).

Tests: new negative/positive coverage in test_skillscan_native.py. Full
backend suite 6616 passed, 26 skipped.

feat(gateway): refuse multi-worker startup on non-Postgres backends (#3960)
Why: issue #3948 identifies four correctness breakers when
GATEWAY_WORKERS > 1. Work item 1 adds a startup gate that refuses
to boot when database.backend is not postgres, giving operators a
clear error instead of silent SQLite write-lock corruption.

The gate runs inside langgraph_runtime() before
init_engine_from_config, so a misconfigured deploy never opens a
listener or writes to disk. Non-integer env values fall back to 1
so uvicorn's own validation is unaffected.

feat(memory): add staleness review to prune silently-outdated facts (#3860)
* feat(memory): add staleness review to prune silently-outdated facts

Facts created long ago may become outdated without any future conversation
explicitly contradicting them ("Silent Staleness").  This adds a staleness
review mechanism that surfaces aged facts to the LLM during the normal
memory-update call so it can semantically judge whether each is still valid.

- New MemoryConfig fields: staleness_review_enabled, staleness_age_days,
  staleness_min_candidates, staleness_max_removals_per_cycle,
  staleness_protected_categories
- New STALENESS_REVIEW_PROMPT section injected into MEMORY_UPDATE_PROMPT
  when enough stale candidates exist
- New staleFactsToRemove output field in the LLM response schema
- Safety cap limits max removals per cycle, keeping lowest-confidence
  entries when the LLM returns more than the cap
- Correction facts (category=correction) are protected by default
- Observability via structured logging of each removal with reason
- 32 unit tests covering parsing, selection, triggers, formatting,
  normalization, safety cap, and integration

* fix(memory): add deterministic guardrail for staleness removals

_apply_updates previously removed any fact id the LLM returned in
staleFactsToRemove without verifying it was in the actual staleness
candidate set.  An LLM slip could silently delete protected-category
facts (e.g. correction) or fresh facts, defeating the stated guarantee.

Now intersect stale_ids_to_remove with _select_stale_candidates before
the safety cap, making the protection independent of both model behavior
and the staleness_review_enabled flag.

Add three regression tests:
- test_protected_category_fact_refused_at_apply
- test_non_aged_fact_refused_at_apply
- test_guardrail_runs_when_staleness_review_disabled

* docs(memory): sync AGENTS.md staleness config + simplify datetime parsing

Address reviewer feedback from PR #3860:
- Add staleness workflow step and 5 new config fields to backend/AGENTS.md
- Simplify _parse_fact_datetime: drop manual Z→+00:00 replace, Python 3.12+ fromisoformat handles Z natively

feat: add branching support for assistant turns (#3950)
* 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

* style: refine workspace change badge scale

* fix: restore workspace change user context import

* fix(frontend): gate workspace change badge to assistant messages

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

feat(skills): bind request-scoped secrets for autonomously-invoked skills (A+) (#3938)
* feat(skills): bind request-scoped secrets for in-context (autonomously invoked) skills

Extends the #3861 binding point A (slash-activation only) to A+: the
injection set is recomputed on every model call from two unioned
sources — the run's most recent slash activation (persisted on the run
context so the tool loop keeps the binding) and skills the model
actually loaded in this thread (ThreadState.skill_context), re-validated
against the live registry each call.

Authorization stays three-gated regardless of activation style: skill
enabled by the operator, values supplied per-request by the caller in
context.secrets (never persisted server-side, never from the host env),
names declared in the skill's required-secrets frontmatter. Because the
set is replaced per call, eviction from skill_context or a caller that
stops supplying a value revokes injection on the next call.

New frontmatter field secrets-autonomous (default true) lets a skill
restrict binding to explicit slash activation; malformed values fail
closed to false. Binding changes are recorded as a
middleware:skill_secrets journal event carrying names only.

Design informed by a survey of peer systems (Claude Code, Codex CLI,
opencode, pi, deepagents, hermes-agent, QwenPaw) and specs
(agentskills.io, MCP 2025-11-25): the industry trust boundary is
enable-time consent plus caller-scoped credentials, not per-invocation
ceremony; no surveyed system scopes secrets to an activation turn.

Part of #3914

* refactor(skills): centralize secret context keys, document intentional per-call reload

Review follow-ups (no behavior change): move the two private binding keys
(__slash_skill_secret_source, __skill_secrets_binding_audit) into
secret_context.py and add them to REDACTED_CONTEXT_KEYS so the redaction
allowlist stays a complete guard even though both keys hold names only.
Document why _in_context_secret_sources reloads skills every call rather
than caching: load_skills re-reads enabled state so an operator disabling
a skill revokes its binding on the next model call — an mtime cache would
miss enable/disable toggles and keep injecting after a disable.

* fix(skills): match in-context secret bindings by path only, never by name

Review finding (confused deputy): _in_context_secret_sources fell back to
name matching when a skill_context path did not resolve. DeerFlow lets a
custom skill shadow a same-named public/legacy one (load_skills de-dupes
by name, custom wins), so a thread that read public/foo could bind the
custom foo's declared secrets although the custom skill was never loaded
in the thread. The recent user-isolation path changes make by-path misses
(and thus the dangerous fallback) more likely. Drop the by-name fallback:
match strictly by the exact container file path the model read; an
unresolved path simply does not bind (the safe direction). Regression
tests cover the shadowing case and a stale path.

Part of #3914

* fix(skills): resolve secret-binding sources via registry; strip caller __-keys

Security review (willem-bd, #3938):

1. Forged `__slash_skill_secret_source` bypassed the enabled/allowlist/
   secrets-autonomous gates. runtime.context is caller-mergeable, and the
   slash source was trusted as authoritative (its stored requirements were
   injected directly). Now the slash source records only the activated
   skill's canonical container path, and BOTH the slash and in-context
   sources resolve the live registry skill by normalized path each call
   (_resolve_registry_skill) — binding only that real, enabled, allowlisted
   skill's own declared secrets. A forged path resolves to nothing. As
   defense in depth, build_run_config strips caller-supplied __-prefixed
   context keys at the gateway boundary.
2. Malformed caller requirements crashed the run (unguarded tuple unpack /
   DoS). The middleware no longer unpacks caller-provided requirement data
   at all — declarations come from the registry — so a malformed source
   fails closed instead of raising.
3. Path-normalization asymmetry silently disabled in-context binding on a
   trailing-slash container_path config. Both the registry keys and the
   lookup path are now posixpath.normpath'd.

Regression tests: forged source rejected, forged-but-real path ignores
caller requirements + allowlist, malformed source fails closed, trailing-
slash config binds, gateway strips __-keys.

Part of #3914

* docs(skills): correct _SLASH_SECRET_SOURCE_KEY comment and note fail-closed trade-off

Post-review cleanup: the key now stores only the canonical container path
(the comment still described the pre-fix skill-name+requirements shape),
and document that a transient registry-load failure fails closed (drops
the binding for that call) rather than trusting stale data.

feat(gateway): cache-aware cost accounting (#3920)
* feat(gateway): cache-aware cost accounting + /api/console observability endpoints

- Capture prompt-cache hits (usage_metadata.input_token_details.cache_read)
  in RunJournal and SubagentTokenCollector as a sparse cache_read_tokens key
  in token_usage_by_model (JSON field — no schema migration; legacy bucket
  shapes unchanged)
- New read-only /api/console router: GET /stats (headline counters),
  GET /runs (cross-thread paginated history joined with thread titles),
  GET /usage (zero-filled daily token series + per-model breakdown);
  user-scoped, 503 on the memory database backend
- Optional models[*].pricing (currency, input_per_million,
  output_per_million, input_cache_hit_per_million) powers real spend
  estimation; cache-hit input tokens are billed at the hit price (omitted
  hit price falls back to the miss price as a conservative upper bound);
  unpriced models yield cost: null
- create_chat_model strips the presentation-only pricing block so it never
  reaches the provider client (unknown kwargs are forwarded into the
  completion payload and break live calls)
- Tests: console router SQLite round-trips, journal/collector cache capture
  incl. a DeepSeek raw-usage pin test, factory strip regression

feat(channels): add GitHub as a webhook-driven channel (#3754)
* feat(channels): add GitHub event-driven agents (#3754)

Add a webhook-driven GitHub channel with fail-closed webhook routing, deterministic per-agent PR/issue threads, mention-gated trigger fan-out, GitHub App token injection for sandboxed gh/git commands, and backend/AGENTS.md documentation.

* fix(llm-middleware): classify bare IndexError as transient

Upstream chat providers occasionally return 200 OK with an empty
generations list (observed against Volces "coding" on
ark.cn-beijing.volces.com). When that happens,
langchain_core.language_models.chat_models.ainvoke raises
``IndexError: list index out of range`` at
``llm_result.generations[0][0].message`` and kills the run.

Treat a bare IndexError reaching the middleware as a transient
upstream-payload glitch and route it through the existing
retry/backoff path instead of failing the whole agent run. The
retry budget and backoff schedule are unchanged.

Adds three regression tests covering the classifier and both the
recover-on-retry and exhausted-retries paths.

* fix(runtime): ignore stale LLM fallback markers from prior runs

When a run on a thread ends with the LLM-error-handling middleware emitting
a `deerflow_error_fallback`-marked AIMessage (e.g. after the IndexError
empty-generations classification fix lands), that message is persisted to
the thread's checkpoint as part of the messages channel. LangGraph replays
the full message history in `stream_mode="values"` chunks, so every
subsequent run on the same thread re-streams the stale fallback marker —
and the worker's chunk scanner faithfully picks it up, flipping
`RunStatus.success` to `RunStatus.error` for runs that themselves had
no LLM failure at all.

Snapshot the set of pre-existing message ids from the pre-run checkpoint
and thread it through `_extract_llm_error_fallback_message` /
`_try_extract_from_message` as a filter. Markers on history messages are
ignored; markers on fresh messages produced during this run still trip
the error path. Falls back to an empty set when the checkpointer is
absent or the snapshot can't be captured, preserving the prior behavior
on first-run / no-state paths.

Adds unit tests for the new filter (helper-level and `_collect_pre_existing_message_ids`)
plus an integration test exercising the full `run_agent` path with a stale
history checkpointer.

* fix(channels): make github channel fire-and-forget to avoid httpx.ReadTimeout on long runs

GitHub agent runs (clone -> edit -> test -> push -> PR) routinely exceed
the langgraph_sdk default 300s read deadline. The manager's runs.wait
call kept an HTTP stream open for the entire run lifetime, so the long
run blew up with httpx.ReadTimeout and the outer except branch then
released the dedupe key and emitted a false 'internal error' outbound.

The GitHub channel's outbound send is log-only by design: agents post to
the issue/PR via the gh CLI in the sandbox when they choose to comment
or create a PR. There is nothing for the manager to ferry back, so the
long-poll was pure overhead.

This change adds ChannelRunPolicy.fire_and_forget (default False) and
sets it True for the github channel. When fire_and_forget is True,
_handle_chat dispatches via client.runs.create (short POST, returns
once the run is pending) instead of client.runs.wait, and skips the
response-extraction + outbound-publish block. ConflictError on a busy
thread still trips the standard THREAD_BUSY_MESSAGE path so behavior on
the busy case is preserved for any future non-github fire-and-forget
channel.

Other (non-github) channels are unchanged: their policy defaults
fire_and_forget=False and they continue to dispatch via runs.wait.

Adds 6 regression tests in tests/test_channels.py::TestGithubFireAndForget:
- Default ChannelRunPolicy.fire_and_forget is False.
- The github policy registers fire_and_forget=True.
- github inbound calls runs.create, not runs.wait, with the right kwargs.
- github inbound publishes no outbound on success.
- ConflictError from runs.create still emits THREAD_BUSY_MESSAGE.
- Non-github channels (slack) still dispatch via runs.wait.

* test(lead-agent): accept user_id kwarg in skill-policy test stubs

The two GitHub-channel tests added in #3754 stubbed
_load_enabled_skills_for_tool_policy with a lambda that only accepted
`available_skills` and `app_config`, but the real function (and its call
site in agent.py) also passes `user_id`. This raised TypeError on every
run, failing backend-unit-tests.

Add `user_id=None` to match the three sibling stubs in the same file.

* refactor(gateway): disambiguate context-key set names

The two frozensets _INTERNAL_ONLY_CONTEXT_KEYS and _CONTEXT_ONLY_KEYS
shared a confusable "CONTEXT_ONLY" token in different orders, and the
first broke the _CONTEXT_<X>_KEYS pattern of its sibling
_CONTEXT_CONFIGURABLE_KEYS. Rename to make the distinct axes explicit:

  _CONTEXT_INTERNAL_CALLER_KEYS  - WHO: internal callers (scheduler) only
  _CONTEXT_RUNTIME_ONLY_KEYS     - WHERE: runtime context only, never configurable

Pure rename, no behavior change.

feat: add scheduled tasks MVP (#3898)
* 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

feat(channels): expose IM channel_user_id to sandbox commands as DEERFLOW_CHANNEL_USER_ID (#3926)
* feat(channels): expose channel_user_id to sandbox commands as DEERFLOW_CHANNEL_USER_ID

IM-channel skills need the sender's platform identity (Feishu open_id,
Slack Uxxx, ...). The channel manager already writes channel_user_id into
body.context, but the Gateway whitelist dropped it. Forward it into the
runtime context only (never configurable, which is checkpointed), and have
bash_tool export it as a fixed env var through a shell-quoted command
prefix.

The identity deliberately does not ride execute_command(env=...): that
channel is reserved for request-scoped secrets, and a non-empty env
switches AioSandbox onto the bash.exec path (fresh session per call,
image >= 1.9.3 required), which would have broken every IM bash command
on older sandbox images and abandoned persistent-shell semantics on new
ones. A command-string export keeps the legacy path, stays visible in
audit logs (it is an identifier, not a secret), and gives per-call
correctness in group chats where one thread and sandbox are shared by
senders with different platform ids.

Skipped on the Windows local sandbox, whose PowerShell/cmd.exe fallback
has no POSIX export.

* feat(channels): propagate channel_user_id to subagents; cap value length

Review findings from the pre-PR verification pass:

- Subagent delegation dropped the sender identity: task_tool now captures
  channel_user_id from the parent runtime context and the executor
  forwards it into the subagent's context, mirroring the guardrail
  attribution fields (user_role/oauth_*/run_id). Without this, bash
  commands delegated via task lost the group-chat sender's id.
- body.context is client-writable on web requests, so values over 256
  chars are ignored instead of bloating every command string sent to the
  sandbox.

* fix(channels): set-or-unset channel_user_id so identity is per-call regardless of AIO session persistence

Review (willem-bd): the identity export could leak across senders in a
shared group-chat AIO sandbox. The AIO no-env path reuses a persistent
shell session (the class-lock reason, #1433), and the 256-char/type guard
made some commands carry no prefix — so a dropped-id command could resolve
the id a previous sender exported.

Make per-call correctness independent of session semantics: an IM-channel
command (channel_user_id present in context) now always carries an explicit
prefix — export VAR=<quoted> for a valid id, or unset VAR for an unusable
one (empty / non-str / over the cap). Non-IM runs (no key) are untouched.
A prefix unset has none of the '& ; unset' suffix hazard raised earlier.

Verified on a real AIO 1.11.0 container: the no-id shell path auto-creates
a session per call (does not persist today), but an explicit shared session
DOES persist (export stale-A -> readback [stale-A]); the unset prefix
clears it (-> []). So the fix holds even on an image whose no-id path
persists. Regression tests cover the dropped-id group-chat window and the
non-IM passthrough.

Part of #3914

* test(channels): align channel_user_id task test with new Command return shape

The merge from main changed task_tool to return a Command(update=...)
instead of a plain string; update the assertion to extract the tool
message via the existing _task_tool_message helper, matching the sibling
tests. Fixes the CI backend-unit-tests failure introduced by the merge.

feat(skills): per-user custom skill isolation with sandbox mounting (#3889)
* feat(skills): per-user skill isolation (#2905)

Implement user-scoped skill storage that isolates custom skills between
users while sharing public skills globally.

Key changes:
- Add UserScopedSkillStorage class for per-user custom skill directories
- Introduce get_or_new_user_skill_storage() factory with user_id context
- Auth middleware sets effective_user_id for request-scoped storage
- Agent/prompt/middleware now use user-scoped storage and prompt cache
- Sandbox mounts user-scoped skill directories for search/read tools
- Add validate_skill_file_path() to SkillStorage for path security
- Migration script supports --all-users bulk migration
- Frontend: add editable field to Skill type, error check in enableSkill
- All skill categories can be toggled (custom skills default to enabled)
- Update skill-creator SKILL.md with isolation-aware instructions

Tests:
- Add test_user_scoped_skill_storage.py (new)
- Update all existing skill tests for user-scoped storage
- Update sandbox, client, and router tests

* fix(skills): address second-round PR review feedback (#3889)

- P1-1: restrict legacy skill mount to users without custom skills
- P1-2: fail-closed for _is_disabled_skill_path (OSError → return True)
- P2-1: AND-merge global extensions_config skill disabled state
- P2-2: atomic write for _skill_states.json (mkstemp + replace)
- P2-3: normalize X-DeerFlow-Owner-User-Id in trusted boundary
- P2-4: LRU-bounded _enabled_skills_by_config_cache (OrderedDict, maxsize=256)
- P2-5: clear global prompt cache on PUBLIC skill toggle
- P2-6: invalidate skill caches on client.update_skill

* fix(tests): correct tool policy test after merge

* fix(skills): use DEFAULT_SKILLS_CONTAINER_PATH in UserScopedSkillStorage

The "/mnt/skills" literal in UserScopedSkillStorage.__init__ triggers
test_skill_container_path_defaults::test_mnt_skills_literal_is_owned_by_skill_constants_module
on CI. Migrate the default to the existing deerflow.constants constant,
matching the pattern already used by LocalSkillStorage, SkillStorage, and
the durable/tool_error middlewares.
