* fix(harness): complete Lark device auth via a single-flight login run
The web authorization polling loop reused the request wait budget as the
lark-cli auth login subprocess lifetime: each /lark/auth/complete poll ran
the CLI with subprocess timeout=wait_timeout_seconds (8s from the frontend)
and killed it on timeout. The login transaction is not atomic — poll, redeem
the single-use device code, fetch user info, then persist credentials — so a
kill after redemption but before persistence stranded the flow, and the next
poll with the same code failed with 'device_code is invalid'.
Own the login process by the flow generation instead: the first poll spawns
one background run per (user_id, generation) and later polls attach to it;
wait_timeout_seconds only bounds the caller's wait (unchanged 504 contract)
and never terminates the CLI. Advancing the generation or re-issuing a device
code abandons and kills the orphaned process, and a finished run's outcome
stays attachable for 120s so late polls return the same result instead of
re-consuming the redeemed code.
* fix(lark): tolerate vanished credential-tree entries and bound owner-alive grace
Publication could kill the login worker with an unhandled FileNotFoundError
when a concurrently-written temp file vanished between iterdir() and lstat(),
leaving the marker live but no result file ever published; every foreign poll
then blocked 504 until the 600 s attempt bound, and could respawn an
already-redeemed code. Also, a bare-pid owner_alive check trusted for the
full 600 s let a recycled-pid or crashed-thread marker outlive any process
that could still publish.
- _credential_tree_path_kind returns "gone" on FileNotFoundError so the
walk skips vanished entries instead of aborting; the same tolerance is
applied to iterdir().
- _write_lark_login_result_once treats the re-harden as best-effort: a
filesystem hiccup is logged and publication continues so the marker sweep
still runs.
- The marker now records owner_pid_started_at and
_read_live_lark_login_marker_locked only keeps an owner-alive marker
within a 10 s publication grace, so a stale marker is swept and the flow
respawns instead of wedging every foreign poll.
Regression: test_walk_and_harden_tolerates_a_vanished_entry,
test_write_result_once_continues_when_hardening_fails,
test_abandoned_marker_with_dead_owner_is_swept_within_grace.
Focused suites: 139 passed, 12 skipped.
* fix(lark): harden surviving credentials through filesystem churn
Atomic login publication can remove a descendant after lstat but before
chmod. Catch FileNotFoundError around the entire per-entry walk so that
lstat, chmod and directory enumeration tolerate those disappearances.
A vanished root, permission error or symlink remains a hard failure.
Exercise real removals at each boundary and concurrent result publication;
assert that injection ran and surviving directories/files reach 0700/0600.
The regressions detect a skipped walk, swallowed permission failures and
loss of directory-churn tolerance in isolated mutation runs.
* fix(lark): retain login ownership through durable completion
Browser approval can take longer than the publication grace. Start that
grace at the first observed CLI exit, then reject abandoned attempts
without retrying a device code that may already have been redeemed.
Serialize atomic result publication under the credential lock. Preserve
published results through cleanup failures and retain terminal failures
on the marker when result storage fails. Never bypass credential hardening.
Reserve storage before spawning and roll back failed marker, process or
thread startup by reaping the CLI, clearing the registry and waking waiters.
Add process/filesystem failure regressions, a long-login two-worker case,
and strict unhandled-thread gates. Fix invocation logging in both workers
and reap forked test CLIs after the parent observes their launch. Document
the authorization lifecycle and required regression assertions.
Validated the reproduced failures and ten isolated mutations; final
focused, blocking-I/O, full-suite and independent review details are in PR #7182.
* fix(mcp): keep rotating OAuth refresh tokens across restarts and Gateway instances
MCP servers on the OAuth refresh_token grant lost their rotated refresh
token whenever a new process or manager started (restart, tool-cache
reset for non-task servers, every personal-connection run, a second
Gateway instance) and re-seeded with the consumed configured token,
getting invalid_grant for good.
- New table mcp_oauth_tokens (migration 0047_mcp_oauth_tokens), one row
per refresh_token connection keyed (scope, owner_user_id, server_key):
('deployment', '', name) or ('personal', owner, personal runtime
name). Access and refresh tokens are DEER_FLOW_CREDENTIALS_KEY
ciphertext; a config fingerprint (token_url, client_id, grant, scope,
audience, seed) makes a changed seed win.
- OAuthTokenManager re-reads the row under its process lock, adopts a
peer's valid token, and otherwise claims the refresh with a lease plus
a version compare-and-set (database clock), fetches outside any
transaction, writes under the lease and releases it on failure.
- The Gateway installs the store (sync engine via to_thread) around the
LangGraph runtime for sqlite/postgres; personal managers pass their
owner. client_credentials stays in process; an unloadable key falls
back to process memory; database errors fail the refresh.
- credentials_key_consumers lists refresh_token MCP OAuth servers, so a
declared multi-instance deployment needs the shared key.
Docs: MCP_SERVER.md, CONFIGURATION.md, Helm README, README, mcp and
migrations AGENTS.md, CHANGELOG (en/zh).
* docs(changelog): link the MCP OAuth token store entry to #7207
* fix(mcp): prune removed connections' OAuth token rows and ask owners to re-authorize on invalid_grant
Review follow-up (willem-bd):
- Both MCP config writers drop mcp_oauth_tokens rows of connections a
save removes (deployment: _commit_mcp_config_write; personal:
_mutate, keeping each connection's enabled/disabled runtime-name
variants so a toggle keeps its chain). Best effort; no startup sweep,
since a missing config file would look like every server removed.
- invalid_grant on a refresh_token request raises
McpOAuthReauthorizationRequired: the tool error names the server and
asks for a new refresh token, plus the shared-key hint when this
instance could not decrypt the stored chain.
- Annotate the gateway helpers' config as AppConfig.
* fix(mcp): renew the OAuth refresh lease, keep unstored rotations, and key access tokens by request parameters
Review follow-up (willem-bd, second round):
- HTTPX timeouts bound each I/O wait, not a whole response: the refresh
holder now renews its lease every third of REFRESH_LEASE_SECONDS while
the token request runs and abandons it after REFRESH_MAX_SECONDS (120 s);
waiters outlast a live holder. Regression uses a real loopback endpoint
that streams its body for three lease lengths.
- A refresh whose tokens could not be stored keeps them pending
(unsaved_base_version): they are written back before an older stored
token is adopted or refreshed with, retried every few seconds while the
access token is still valid, and dropped once a peer stored a newer
chain. A failed save releases the lease.
- New token_request_fingerprint (extra_token_params and response fields):
a stored access token is reused only under the same request parameters;
otherwise the stored refresh-token chain is refreshed.

* docs(skills): align current guides with agent tool authority
* test(skills): simplify authority regressions and sync Korean docs
* fix(channels): keep staging cleanup from replacing the save error
The channel stores publish state through a staged temporary file and, if the
rename fails, close and unlink that file inside the handler before re-raising.
Neither step was guarded, so a failing close skipped the unlink and a failing
unlink replaced the error that actually caused the save to fail -- leaving the
staged copy, which for the runtime-config and WeChat stores holds an 0600 IM
token, behind with nothing reporting it.
Make both steps independently best-effort, name the leaked file in a WARNING,
and suppress the diagnostic itself so a broken log handler cannot become the
reported failure. This is the same contract PR #6871 establishes for browser
captures, applied to the three JSON publishers in app/channels.

* feat(decisions): add an OpenAI Decisions backend for the decision slots
Issue #7005 asked for a second decision provider behind the interfaces the
TypeSafe (Jev) integration already uses, not a new decision system.
`deerflow/openai_decisions` speaks `POST /v1/decisions`: a `noul` question
becomes a `predicate` whose true/false rubric folds into `instructions` (the
endpoint has no criteria field, and dropping it would move the decision
boundary while the adapter kept reporting the same criteria in its policy
identity), answers arrive as an array rather than a mapping, and a refusal is an
answer `type` rather than an HTTP failure -- so it lands in the existing
per-question error channel and each consumer keeps its own failure direction.
Transport is reused rather than copied. `provider_label` and the connection's
`endpoint_path` are the only two seams a dialect needs, so retry and backoff,
the deadline budget, the bounded never-decoded body read and the error taxonomy
keep one owner; `resolve_decisions_connection` pairs the two so a Decisions
connection cannot be built pointing at System One. The three adapters override
their connection resolution, their client, and the value the endpoint judges
(`input` text instead of a `state` object), and inherit thresholds, rubrics,
caches and audit policy unchanged. Wiring stays a `use:` class path, so no
config schema is added.

* fix(memory): quarantine unreadable memory.json in the read-error branch too
MarkdownMemoryStorage._load_memory_file quarantined summaries that failed
to decode as JSON/Markdown, but the earlier except (OSError, UnicodeError)
branch (unreadable bytes, e.g. a UTF-16 BOM) still returned None without
quarantining. The leftover file was then silently overwritten by the next
save, destroying the user's memories with no backup.

* fix(docker): make dev provisioner opt-in via compose profile
Gate the Kubernetes provisioner behind a Compose profile and have the
wrapper enable it only when config selects provisioner sandbox mode.
This lets the default Docker Compose stack start without kubeconfig.
Fixes#3232
* test(docker): render every compose profile in the env-file regression test
main added backend/tests/test_compose_default_bind_host.py, whose _render helper asserted that the dev provisioner still loads ../.env. `docker compose config` without a profile omits profile-gated services, so that assertion failed once the provisioner became opt-in.
Pass `--profile *` from the helper: the test is about an existing .env reaching every service, so it has to render the services a profile gates rather than only the ones `up` starts by default.
* docs(docker): restore script mode and localize direct Compose guidance
The dev provisioner is now opt-in, but the earlier edit also flipped scripts/docker.sh from 100755 to 100644 even though README.md still documents direct `./scripts/docker.sh` invocation. Restore the executable bit.
Also add the direct-Compose guidance to the translated READMEs so readers of README_zh.md, README_ja.md, and README_fr.md learn that `--profile provisioner` selects the Kubernetes mode and the default stack does not need Kubernetes.

* fix(memory): parse a BOM-prefixed DeerMem fact instead of calling it corruption
Facts are hand-editable Markdown files, so a Windows editor can save one as
"UTF-8 with BOM" -- the same exposure #7083 fixed for memory.json. The fact
parser checks `text.startswith("---\n")` against a plain-utf-8 read, so the
BOM makes a valid fact read as "missing YAML front matter" and raises
MemoryStorageCorruption, which the module docs describe as taking down the
whole agent.
Read the fact with utf-8-sig, matching the summary loader and the SOUL.md /
SKILL.md convention already recorded in AGENTS.md. `_parse_listed_fact`
delegates here, so the directory-scan path is covered by the same change.
Measured: the new BOM test fails on the base revision with exactly that
"missing YAML front matter" corruption and passes at head; the no-BOM control
passes both. 49 tests in test_memory_storage.py, 106 across the memory
suites, ruff check/format clean. Mutation-checked: reverting to plain utf-8
fails only the BOM case.

* fix(github-research): resolve the tree against the repository's default branch
The tree command asked for "main" and, when that was missing, for "master".
A repository whose default branch is neither gets a name-guessing fallback, and
when the stale "master" still resolves GitHub returns it happily: the agent is
handed the tree of an abandoned branch and reports it as the current structure.
Ask for HEAD instead, which GitHub resolves to the repository's own default
branch, so no candidate names are guessed and no extra request is added.

[Totoro-qaq: resolved onto main. The persisted-reminder middleware hunks and their tests are dropped (delivery is redesigned in a follow-up); the RunCreateRequest description moved to app/gateway/run_models.py.]
* fix: address client context review comments
(cherry picked from commit bce6da6b819228eda58e887872720b6f9b5fab69)
[Totoro-qaq: middleware hunks dropped with the redesigned delivery.]
* feat(agents): deliver client context as a request-scoped data block
The cherry-picked #3106 put context.client into the persisted first-turn
reminder, with change detection and a "not provided" clear marker. Main
has since moved the date reminder to a SystemMessage, made request-scoped
context (the project block, #5443) request-only, and agents/AGENTS.md now
requires user-influenced values to ride the HumanMessage data channel,
never system text.
Render runtime.context["client"] on every model call in
DynamicContextMiddleware.wrap_model_call/awrap_model_call as one hidden
HumanMessage right after the leading SystemMessages, where DurableContext
puts its data. It is never a state update and never flagged
dynamic_context_reminder, so nothing is checkpointed, summarized or
replayed, and a run without a client gets no block. An unchanged client
keeps the previous request as the next request's prefix.
The renderer sanitizes again (direct graph callers bypass the Gateway),
html-escapes values and frames them with frame_untrusted_text: the same
--- BEGIN/END USER INPUT --- boundary the user's own turn and the MCP task
notification get. The lead prompt treats everything outside those markers
as framework data, so unframed values would rank above the user's own
text; framed, context.client can say nothing the same caller could not
already say in input.messages. client_context joins _BLOCKED_TAG_NAMES so
a forged block in user input or a tool result is escaped, and one static,
value-free sentence in the lead prompt names the block as untrusted hints,
never instructions, permissions or identity. The now unused empty-context
marker is removed.
* fix(gateway): log dropped context.client fields without values
A run request is never rejected over context.client: unknown fields,
nested values and malformed entries are silently dropped, the same
leniency as the other context keys. That left no signal when a custom
client sent something the Gateway ignored (review on #3106).
Route both the config.context.client and the body context.client paths
through one helper that emits a debug line whenever sanitizing changed
the value. Like the malformed client_timezone branch, the line carries no
values; unlike client_timezone, client.name and preference strings are
free caller-controlled text, so they are never logged, not even
sanitized. A clean client, an explicit null or an absent key logs
nothing.
Tests also pin the config-only path (sanitized before the early return)
and the end-to-end start_run admission: the sanitized client reaches
config["context"] and never configurable.
* fix(runtime): bound numeric client context preferences
String preferences are capped at 200 characters, but integers were kept
at any size. A JSON body may carry integers of up to 4300 digits, so 32 of
them rendered a block of about 138,000 characters, re-sent on every model
call of the run. In-process callers could also pass an int past the str()
digit limit, which failed the model call, or a number subclass with its
own __str__.
Keep integers within JavaScript's Number.MAX_SAFE_INTEGER, the range a
browser client can send exactly, and coerce numbers to plain int and
float.
* docs(api): describe client context as advisory request-scoped hints
The cherry-picked section described a hidden reminder that no longer
exists. Document what a custom client can rely on: the allow-list and its
limits (strings, the integer range, and only the first 32 entries of each
map), debug-level logging of dropped fields, runtime-only forwarding, and
delivery as a per-request user-role block, framed like user input, rather
than system text or thread history.
Only top-level context.client is documented. An explicit
config.context.client is sanitized for the run as well, but the run record
keeps the caller's config as sent, so it is not offered as an alternative.
It also answers the #3106 review: capabilities and preferences are
advisory hints, not enforcement, which belongs outside the model; name is
informational and never for authorization; the same object should be
sent on every run to keep the cached prefix stable; subagents and
embedded DeerFlowClient runs do not receive it, and server-started runs
(schedules, IM channels, GitHub agents, MCP notifications, extensions
unless the plugin passes one) carry none.
* fix(context): declare client delivery and keep client out of configurable
The request-only <client_context> block is model-visible, so
DynamicContextMiddleware now declares its delivery and the sanitizer's
limits in release_policy_parameters(); runs before and after this change
no longer share a policy fingerprint.
build_run_config copies body.config['configurable'] verbatim and
configurable is persisted with checkpoints, so a client placed there is
dropped instead of being stored raw. Client context stays runtime-only.
Document context.client in the README and in the middleware guide.
* fix(context): apply the PII redaction policy to the client block
DynamicContextMiddleware adds the <client_context> message inside the
outer PiiRedactionMiddleware, and the hidden message is not re-sanitized,
so with pii_redaction enabled a preference such as an email address
reached the model verbatim while the same address in the user turn was
redacted. Pass the rendered block through the shared redact_text seam
with this middleware's app_config.pii_redaction, and declare the setting
in release_policy_parameters().
* fix(context): keep client hints out of stored run config

* fix(searxng): contain malformed search payloads instead of crashing on them
`_search_page` indexed the decoded body directly:
data = resp.json()
return data.get("results") or []
so a self-hosted instance that answers HTTP 200 with something other than a
result page -- an HTML or plain-text error page from a reverse proxy or captive
portal -- reached the model as a raw Python error, or as an empty search:
{"results": "maintenance window"} -> {"error": "'str' object has no attribute 'get'"}
{"results": {"a": 1}} -> {"error": "'str' object has no attribute 'get'"}
{"results": [1, 2, 3]} -> {"error": "'int' object has no attribute 'get'"}
{"results": [None]} -> {"error": "'NoneType' object has no attribute 'get'"}
Worse, a single malformed entry in an otherwise valid page crashed the whole
call and discarded every good row:
{"results": [{"title": "ok", ...}, 7]} -> {"error": "'int' object has no attribute 'get'"}
This is the containment rule the sibling providers already follow (brave #6550,
groundroute #6603, tavily #6645, sofya #6719, serper #6779, serply #6796,
tencent-wsa #6799): a payload that is not a result page is a format error, not an
empty result, because "No results found" tells the agent the query legitimately
matched nothing and ends a research loop as "no hits".
The client now raises `SearxngResponseError` for a payload that is not an object,
a body that is not JSON, a `results` container that is not a list, and a
non-empty list holding no object entries, while still skipping non-object entries
in an otherwise valid page so the valid rows survive. `web_search_tool` reports
the provider's format error instead of leaking the exception text. Missing, null,
and empty `results` keep the existing "No results found" behavior.
Diagnostics log the container field name and its type, or the absence of usable
objects -- never the query, credentials, or payload values.
* test(searxng): pin the mid-walk format-error trade-off and fix the docstring
The paginating client aborts the walk and discards already-collected rows when
a later page comes back malformed, which is a different outcome from the
single-request siblings. Pin that trade-off with a test so the behaviour is a
deliberate decision rather than an accident, and reword the
_unexpected_format_error docstring: it promises the query is not echoed, but
the sibling providers all echo it back on purpose and only withhold the
payload.
* test(searxng): log skipped entries and pin the dedicated format-error handler
Two follow-ups from review, both about making the family contract observable
and pinned:
- Skipped non-object entries now log their index ("Skipping malformed SearXNG
result entry at results[1]"), matching the merged InfoQuest sibling. SearXNG
is the provider where drift is most expected -- a self-hosted instance serves
whatever sits behind its reverse proxy -- and a search spans up to
_MAX_PAGES requests, so rows could otherwise be shed with no trace at all.
- The dedicated `except SearxngResponseError` branch had no test that could
fail: the exception is a ValueError whose message is already the format-error
string, so the generic handler returns byte-identical JSON. The new test
asserts the generic branch's log line is absent, which is what actually
distinguishes the two paths.
* docs(searxng): name the empty result it actually returns, and pin the dedicated except
Two low findings from the follow-up review:
- The README said missing/null/empty `results` keep the existing "No results
found" response. That response does not exist in this provider: all three
produce a JSON empty list, and the string appears only in comments
explaining what must NOT be reported. The family convention distinguishes
(Tavily: "`[]` for search, Error: No results found for fetch"; InfoQuest:
"keep the existing empty result"), so this now reads "keep the existing
empty result (`[]`)".
- The client-level `except SearxngResponseError: raise` was unpinned: deleting
it left the whole file green, because the tool-level test mocks the client
and the payload tests only assert the raise type. The observable regression
is the generic branch logging "An unexpected error occurred" for every
contained page, so the existing payload test now asserts that line is absent
from caplog.
Mutation check: removing the clause now fails 8 parameterised cases (was 33
green); with the clause in place the suite is 33 passed and 91 across the two
provider files, ruff check/format clean.
