feat(loop-detection): make loop detection configurable with per-tool frequency overrides (#2711)
* Make loop detection configurable Expose LoopDetectionMiddleware thresholds through config.yaml while preserving existing defaults and allowing the middleware to be disabled. Refs bytedance/deer-flow#2517 * feat(loop-detection): add per-tool tool_freq_overrides to Phase 1 Adds ToolFreqOverride model and tool_freq_overrides field to LoopDetectionConfig, wires it through LoopDetectionMiddleware, and documents the option in config.example.yaml. Resolves the gap flagged in the #2586 review: without per-tool overrides, users hit by #2510/#2511 (RNA-seq workflows exceeding the bash hard limit) had no way to raise thresholds for one tool without loosening the global limit for every tool. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * docs(loop-detection): document tool_freq_overrides in LoopDetectionMiddleware docstring Add the missing Args entry for tool_freq_overrides, explaining the (warn, hard_limit) tuple structure and how per-tool thresholds supersede the global tool_freq_warn / tool_freq_hard_limit for named tools. Also run ruff format on the three files flagged by the lint check. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(loop-detection): validate LoopDetectionMiddleware __init__ params eagerly Raise clear ValueError at construction time instead of crashing at unpack-time inside _track_and_check when bad values are passed: - tool_freq_overrides: must be 2-tuples of positive ints with hard_limit >= warn - scalar thresholds: warn_threshold, hard_limit, tool_freq_warn, tool_freq_hard_limit must be >= 1 and hard limits must >= their warn pairs - window_size, max_tracked_threads must be >= 1 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(test): isolate credential loader directory-path test from real ~/.claude The test didn't monkeypatch HOME, so on any machine with real Claude Code credentials at ~/.claude/.credentials.json the function fell through to those credentials and the assertion failed. Adding HOME redirect ensures the default credential path doesn't exist during the test. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * style(test): add blank lines after import pytest in TestInitValidation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(loop-detection): collapse dual validation to LoopDetectionConfig Modifications - LoopDetectionMiddleware.__init__: stripped of all ValueError raises; becomes a plain field-assignment constructor. - LoopDetectionMiddleware.from_config: classmethod that builds the middleware from a Pydantic-validated LoopDetectionConfig and handles the ToolFreqOverride -> tuple[int, int] conversion. - agents/factory.py: SDK construction routed through LoopDetectionMiddleware.from_config(LoopDetectionConfig()) so the defaults path is Pydantic-validated too. - agents/lead_agent/agent.py: uses from_config instead of unpacking config fields by hand. - tests/test_loop_detection_middleware.py: deleted TestInitValidation (16 methods exercising the removed __init__ checks); added TestFromConfig (4 tests: scalar field mapping, override tuple conversion, empty overrides, behavioral smoke test). Result: one validation layer (Pydantic), zero duplication, no __new__ hacks. Both production construction sites flow through LoopDetectionConfig. Test results make test -> 2977 passed, 18 skipped, 0 failed (137s) make format -> All checks passed; 411 files left unchanged * feat(agents): make loop_detection configurable in create_deerflow_agent Adds a `loop_detection: bool | AgentMiddleware = True` field to RuntimeFeatures, mirroring the existing pattern used by `sandbox`, `memory`, and `vision`. SDK users can now disable LoopDetectionMiddleware or replace it with a custom instance built from their own LoopDetectionConfig — e.g. `LoopDetectionMiddleware.from_config(my_cfg)` — instead of being stuck with the hardcoded defaults previously installed by the SDK factory. The lead-agent path (which already reads AppConfig.loop_detection) is unchanged, and the default `True` preserves prior always-on behavior for all existing callers.

feat(agent): add custom-agent self-updates with user isolation (#2713)
* feat(agent): add update_agent tool for in-chat custom-agent self-updates (#2616) Custom agents had no built-in way to persist updates to their own SOUL.md / config.yaml from a normal chat — `setup_agent` was only bound during the bootstrap flow, so when the user asked the agent to refine its description or personality, the agent would shell out via bash/write_file and the edits landed in a temporary sandbox/tool workspace instead of `{base_dir}/agents/{agent_name}/`. Changes: - New `update_agent` builtin tool with partial-update semantics (only the fields you pass are written) and atomic temp-file + os.replace writes so a failed update never corrupts existing SOUL.md / config.yaml. - Lead agent now binds `update_agent` in the non-bootstrap path whenever `agent_name` is set in the runtime context. Default agent (no agent_name) and bootstrap flow are unchanged. - New `<self_update>` system-prompt section is injected for custom agents, instructing them to use `update_agent` — and explicitly NOT bash / write_file — to persist self-updates. - Tests: 11 new cases in `tests/test_update_agent_tool.py` covering validation (missing/invalid agent_name, unknown agent, no fields), partial updates (soul-only, description-only, skills=[] vs omitted), no-op detection, atomic-write safety, and AgentConfig round-tripping; plus 2 new cases in `tests/test_lead_agent_prompt.py` covering the self-update prompt section. - Docs: updated backend/CLAUDE.md builtin tools list and tools.mdx (en/zh) with the new tool description. * feat(agent): isolate custom agents per user Store custom agent definitions under the effective user, keep legacy agents readable until migration, and cover API/tool/migration behavior with tests.

fix(channels): preserve clarification conversation history across follow-up turns (#2444)
* fix(channels): preserve clarification conversation history across follow-up turns Pin channel-triggered runs to the root checkpoint namespace and ensure thread_id is always present in configurable run config so follow-up replies resume the same conversation state.

feat(community): add Serper web search provider (#2630)
* feat(community): add Serper web search provider Add a new community search provider backed by the Serper Google Search API (https://serper.dev). Serper returns real-time Google results via a simple JSON API and requires only an API key — no extra Python package. Changes: - backend/packages/harness/deerflow/community/serper/__init__.py - backend/packages/harness/deerflow/community/serper/tools.py Implements web_search_tool using httpx (already a project dependency). API key is read from config.yaml `api_key` field or SERPER_API_KEY env var. Follows the same interface / output shape as the existing ddg_search provider. Exposes max_results parameter (default 5) with config override logic. - backend/tests/test_serper_tools.py Unit tests covering API key resolution, config overrides, HTTP errors, empty results, and parameter passing. - config.example.yaml: add commented-out Serper example alongside other providers - .env.example: add SERPER_API_KEY placeholder Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Fix the lint error * Fix the lint error --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(gateway): return ISO 8601 timestamps from threads endpoints (#2599)
* fix(gateway): return ISO 8601 timestamps from threads endpoints (#2594) ThreadResponse documents created_at / updated_at as ISO timestamps, matching the LangGraph Platform schema (langgraph_sdk.schema.Thread exposes them as datetime, JSON-encoded as ISO 8601). The gateway threads router was instead emitting str(time.time()) — unix-second floats — breaking frontend new Date() parsing and producing a mixed ISO/unix wire format that also corrupted the search sort order. Centralize timestamp generation in deerflow.utils.time: - now_iso() — datetime.now(UTC).isoformat() - coerce_iso(x) — heals legacy unix-timestamp strings on read so the store converges to ISO without a one-shot migration threads.py: replace 6 time.time() call sites with now_iso(); wrap all read paths and Phase-2 checkpoint metadata with coerce_iso(); _store_upsert opportunistically heals legacy created_at on update; drop unused time import. thread_runs.py: reuse now_iso() instead of a private duplicate _now_iso(), preventing future drift between the two timestamp call sites. Tests: 9 unit tests for the helper; 5 integration tests pinning the ISO contract for create/get/patch/search and the legacy-healing path on the internal store upsert. Full suite: 2144 passed, 15 skipped, 0 failed. Closes #2594 * fix(gateway): coerce checkpoint metadata timestamps to ISO on read After the merge with main, three additional read paths in ``threads.py`` were still emitting raw ``str(metadata.get("created_at", ""))`` — ``get_thread_state``, ``update_thread_state``, and ``get_thread_history``. Same root cause as #2594: when the checkpoint metadata's ``created_at`` is a unix-second float (legacy data, or a checkpoint written by an older Gateway version), ``str(float)`` produces ``"1777252410.411327"`` and the frontend's ``new Date(...)`` returns ``Invalid Date``. The fix on the ``/threads/{id}`` GET path was already in place; these three sibling endpoints needed the same treatment. All four call sites now flow through ``coerce_iso``, so: - legacy float metadata heals to ISO on the way out, - ISO metadata passes through unchanged, - ``datetime`` instances (which the new ``coerce_iso`` branch handles explicitly) emit with the ``T`` separator instead of falling through to the space-separated ``str(datetime)`` form. Coverage added for the two endpoints not already pinned by the merge: - ``test_get_thread_state_returns_iso_for_legacy_checkpoint_metadata`` - ``test_get_thread_history_returns_iso_for_legacy_checkpoint_metadata`` Both pre-seed a checkpoint whose metadata carries the literal float from the issue body and assert the wire format is ISO. |

refactor: thread app_config through lead and subagent task path (#2666)
* refactor: thread app config through lead prompt * fix: honor explicit app config across runtime paths * style: format subagent executor tests * fix: thread resolved app config and guard subagents-only fallback Address two PR review findings: 1. _create_summarization_middleware passed the original (possibly None) app_config into create_chat_model, forcing the model factory back to ambient get_app_config() and risking config drift between the middleware's resolved view and the model's view. Pass the resolved AppConfig instance through end-to-end. 2. get_available_subagent_names accepted Any-typed config and forwarded it to is_host_bash_allowed, which reads ``.sandbox``. A SubagentsAppConfig (also accepted upstream as a sum-type input) has no ``.sandbox`` attribute and would be silently treated as "no sandbox configured", incorrectly disabling the bash subagent. Guard on hasattr and fall back to ambient lookup otherwise. Adds regression tests for both paths. * chore: simplify hasattr guard and tighten regression tests - Collapse if/else into ternary in get_available_subagent_names; hasattr(None, ...) is False so the explicit None check was redundant. - Drop comments that narrate the change rather than explain non-obvious WHY (test names already convey intent). - Replace stringly-typed sentinel "no-arg" in regression test with direct args tuple comparison. --------- Co-authored-by: greatmengqi <chenmengqi.0376@bytedance.com> |

fix(sandbox): pass no_change_timeout to exec_command to prevent 120s premature termination (#2685)
* fix(sandbox): pass no_change_timeout to exec_command to prevent 120s premature termination The agent_sandbox library's shell API defaults no_change_timeout to 120 seconds. When AioSandbox.execute_command() called exec_command() without this parameter, commands producing no output for 120s would return with NO_CHANGE_TIMEOUT status even though the script was still running. Pass no_change_timeout=600 to all exec_command calls (matching the client-level HTTP timeout) so long-running commands are not cut short. Fixes #2668 * test(sandbox): add assertions for no_change_timeout in execute_command and list_dir Agent-Logs-Url: https://github.com/bytedance/deer-flow/sessions/2f37bc72-0826-4443-a6ba-e5b78c22fb5a Co-authored-by: WillemJiang <219644+WillemJiang@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> |

fix(subagents): use model override for tools and middleware (#2641)
* fix(subagents): use model override for tools and middleware * fix(config): resolve effective subagent model * fix(subagents): defer app config loading * fix(subagents): fully defer config.yaml load in executor __init__ The previous attempt only relocated the explicit get_app_config() call, but left resolve_subagent_model_name(...) running eagerly in __init__. That helper has its own internal get_app_config() fallback, which still fired when both app_config and parent_model were None and config.model == "inherit" — exactly the path unit tests hit, breaking 21 tests in CI with FileNotFoundError: config.yaml. Skip the eager resolve in __init__ when it would require loading the config file, and defer to _create_agent (which already has the app_config or get_app_config() fallback). |

fix(agents): propagate agent_name into ToolRuntime.context for setup_agent (#2679)
* fix(agents): propagate agent_name into ToolRuntime.context for setup_agent (#2677) When creating a custom agent via the web UI, SOUL.md was always written to the global base_dir/SOUL.md instead of agents/<name>/SOUL.md. Root cause: the bootstrap flow sends agent_name via body.context, but two layers were broken: 1. services.py only forwarded body.context keys into config["configurable"]; config["context"] was never populated. 2. worker.py constructed the parent Runtime with a hard-coded {thread_id, run_id} context, ignoring config["context"] entirely. After the langgraph >= 1.1.9 bump (#98a5b34f), ToolRuntime.context no longer falls back to configurable, so setup_agent's runtime.context.get("agent_name") returned None and the tool's silent agent_name=None -> base_dir fallback kicked in, overwriting the global SOUL.md. Fix: - services.py: extract merge_run_context_overrides() and write the whitelisted context keys into both configurable (legacy readers) and context (langgraph 1.1+ ToolRuntime consumers). - worker.py: extract _build_runtime_context() and merge config["context"] into the Runtime's context (without letting callers override thread_id/run_id). The base_dir fallback in setup_agent_tool.py is left in place because the IM /bootstrap channel command depends on it. That code path can be tightened in a follow-up. Adds regression tests covering both helpers. * Apply suggestions from code review Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> |

fix(config): unify log_level from config.yaml across Gateway and debug entry points (#2601)
Centralize log level parsing in `logging_level_from_config()` and application in `apply_logging_level()` within `deerflow.config.app_config`. - Gateway lifespan applies configured log level on startup - `debug.py` uses shared helpers instead of local duplicates - `apply_logging_level()` targets only `deerflow`/`app` logger hierarchies so third-party library verbosity is not affected; root handler levels are only lowered (never raised) to allow configured loggers through without suppressing third-party output; root logger level is not modified - Config field description updated to clarify scope - Tests save/restore global logging state to avoid test pollution Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> |

fix(memory): replace short-lived asyncio.run() with persistent event loop (#2627)
* fix(memory): replace short-lived asyncio.run() with persistent event loop to prevent zombie httpx connections The memory updater used asyncio.run() inside daemon threads, creating and destroying short-lived event loops on every update. Langchain providers (e.g. langchain-anthropic) cache httpx AsyncClient instances globally via @lru_cache, so SSL connections created on a loop that is subsequently destroyed become zombie connections in the shared pool. When the main agent's lead run later reuses one of these connections, httpx/anyio triggers RuntimeError: Event loop is closed during connection cleanup. Replace the ThreadPoolExecutor + asyncio.run() pattern with a _MemoryLoopRunner that maintains a single persistent event loop in a daemon thread for the process lifetime. Since the loop never closes, connections bound to it never become invalid. The _run_async_update_sync function now submits coroutines to this persistent loop via run_coroutine_threadsafe instead of creating throwaway loops. * update the code to address the review comments * Fix the review comments of 2615 P1 — user_id forwarded through sync path: Added user_id parameter to _prepare_update_prompt, _finalize_update, and _do_update_memory_sync, and forwarded it to get_memory_data(agent_name, user_id=user_id) and save(..., user_id=user_id). The update_memory() entry point now passes user_id through both the executor.submit path and the direct call path. Added TestUserIdForwarding with two regression tests (sync + async) verifying get_memory_data and save receive the correct user_id. P2 — aupdate_memory() delegates to sync: Replaced the model.ainvoke() call with asyncio.to_thread(self._do_update_memory_sync, ...). This eliminates the unsafe async provider client path entirely — all memory updater entry points now use the isolated sync model.invoke() path. Updated the test from asserting ainvoke is awaited to asserting invoke is called and ainvoke is not.

refactor: thread app_config through middleware factories (#2652)
* refactor: thread app_config through middleware factories Continues the incremental config-refactor sequence (#2611 root, #2612 lead path) one layer deeper into the middleware factories. Two ambient lookups inside _build_runtime_middlewares are eliminated and the LLMErrorHandling band-aid removed: - _build_runtime_middlewares / build_lead_runtime_middlewares / build_subagent_runtime_middlewares now require app_config: AppConfig. - get_guardrails_config() inside the factory is replaced with app_config.guardrails (semantically identical — same default-factory GuardrailsConfig — verified by direct equality check). - LLMErrorHandlingMiddleware.__init__ now requires app_config and reads circuit_breaker fields directly. The class-level circuit_failure_threshold / circuit_recovery_timeout_sec defaults are removed along with the try/except (FileNotFoundError, RuntimeError): pass band-aid — the let-it-crash invariant the rest of the refactor enforces. Caller chain (already-resolved app_config sources): - _build_middlewares in lead_agent/agent.py: reorder so resolved_app_config = app_config or get_app_config() is computed BEFORE build_lead_runtime_middlewares is called, then passed as kwarg. - SubagentExecutor: optional app_config parameter (mirrors the lead-agent pattern); _create_agent does the same `or get_app_config()` fallback at agent-build time, so task_tool callers don't need to plumb app_config through yet (typed-context plumbing for tool runtimes is a separate refactor). Tests: - test_llm_error_handling_middleware: _make_app_config helper using AppConfig(sandbox=SandboxConfig(use="test")) — same minimal-config pattern conftest already uses. Three direct LLMErrorHandlingMiddleware() calls each followed by post-construction circuit_breaker mutation fold cleanly into _build_middleware(circuit_failure_threshold=..., circuit_recovery_timeout_sec=...). Verification: - tests/test_llm_error_handling_middleware.py — 14 passed - tests/test_subagent_executor.py — 28 passed - tests/test_tool_error_handling_middleware.py — 6 passed - tests/test_task_tool_core_logic.py — 18 passed (verifies task_tool unchanged behavior) - Full suite: 2697 passed, 3 skipped. The single intermittent failure in tests/test_client_e2e.py::test_tool_call_produces_events is pre-existing LLM flakiness (the test asserts the model decided to call a tool; reproduces 1/3 on unchanged main as well). * fix: address middleware app config review comments * fix: satisfy app config annotation lint * test: cover explicit app config middleware wiring --------- Co-authored-by: greatmengqi <chenmengqi.0376@bytedance.com> |

feat(channels): add DingTalk channel integration (#2628)
* feat(channels): add DingTalk channel integration Add a new DingTalk messaging channel using the dingtalk-stream SDK with Stream Push (WebSocket), requiring no public IP. Supports both plain sampleMarkdown replies and optional AI Card streaming for a typewriter effect when card_template_id is configured. - Add DingTalkChannel implementation with token management, message routing, allowed_users filtering, and markdown adaptation - Register dingtalk in channel service registry and capability map - Propagate inbound metadata to outbound messages in ChannelManager for DingTalk sender context (sender_staff_id, conversation_type) - Add dingtalk-stream dependency to pyproject.toml - Add configuration examples in config.example.yaml and .env.example - Update all README translations with setup instructions - Add comprehensive test suite (test_dingtalk_channel.py) and metadata propagation test in test_channels.py - Update backend CLAUDE.md to document DingTalk channel Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(channels): address PR review feedback for DingTalk integration - Replace runtime mutation of CHANNEL_CAPABILITIES with a `supports_streaming` property on the Channel base class, overridden by DingTalkChannel, FeishuChannel, and WeComChannel - Store stream client reference and attempt graceful disconnect in stop(); guard _on_chatbot_message with _running check to prevent post-stop message processing - Use msg.chat_id as the primary routing key in send/send_file via a shared _resolve_routing helper, with metadata as fallback - Fix process() return type annotation from tuple[str, str] to tuple[int, str] to match AckMessage.STATUS_OK - Protect _incoming_messages with threading.Lock for cross-thread safety between the Stream Push thread and the asyncio loop - Re-add Docker Compose URL guidance removed during DingTalk setup docs addition in README.md - Fix incomplete sentence in README_zh.md (missing verb "启用") Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(docs): restore plain paragraph format for Docker Compose note Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(channels): fix isinstance TypeError and add file size guard in DingTalk channel Use tuple syntax for isinstance() type check to avoid runtime TypeError with PEP 604 union types. Add upload size limit (20MB) before reading files into memory. Narrow exception handlers to specific types. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(channels): propagate markdown fallback errors and validate access token response - Re-raise exceptions in _send_markdown_fallback to prevent partial deliveries (files sent without accompanying text) - Validate _get_access_token response: reject non-dict bodies, empty tokens, and coerce invalid expireIn to a safe default - Add tests for both fixes Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(channels): validate upload response and broaden send_file exception handling - Validate _upload_media JSON response: handle JSONDecodeError and non-dict payloads gracefully by returning None - Broaden send_file exception tuple to include TypeError and AttributeError for unexpected JSON shapes Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(channels): fix streaming race on channel registration and slim outbound metadata - Register channel in service before calling start() to avoid race where background receiver publishes inbound before registration, causing manager to fall back to static CHANNEL_CAPABILITIES - Strip known-large metadata keys (raw_message, ref_msg) from outbound messages to prevent memory bloat from propagated inbound payloads Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Update service.py Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update CLAUDE.md Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> |

fix(security): harden auth system and fix run journal logic bug (#2593)
* fix(security): harden auth system and fix run journal logic bug
- Fix inverted condition in RunJournal.on_chat_model_start that prevented
first human message capture (not messages → messages)
- Pre-hash passwords with SHA-256 before bcrypt to avoid silent 72-byte
truncation vulnerability
- Move load_dotenv() from module scope into get_auth_config() to prevent
import-time os.environ mutation breaking test isolation
- Return generic ‘Invalid token’ instead of exposing specific error
variants (expired, malformed, invalid_signature) to clients
- Make @require_auth independently enforce 401 instead of silently
passing through when AuthMiddleware is absent
- Rate-limit /setup-status endpoint with per-IP cooldown to mitigate
initialization-state information leak
- Document in-process rate limiter limitation for multi-worker deployments
* fix(security): return 429+Retry-After on setup-status rate limit, bound cooldown dict

* fix(security): add versioned password hashes with auto-migration on login
The SHA-256 pre-hash change silently broke verification for any existing
bcrypt-only password hashes. Introduce a <N>$ prefix scheme so hashes
are self-describing:
- v2 (current): bcrypt(b64(sha256(password))) with $ prefix
- v1 (legacy): plain bcrypt, prefixed $ or bare (no prefix)
verify_password auto-detects the version and falls back to v1 for older
hashes. LocalAuthProvider.authenticate() now rehashes legacy hashes to v2
on successful login via needs_rehash(), so existing users upgrade
transparently without a dedicated migration step.
* fix(auth): harden verify_password, best-effort rehash, update require_auth docstring, downgrade journal logging
- password.py: wrap bcrypt.checkpw in try/except → return False for malformed/corrupt hashes instead of crashing
- local_provider.py: wrap auto-rehash update_user() in try/except so transient DB errors don't fail valid logins
- authz.py: update require_auth docstring to reflect independent 401 enforcement
- journal.py: downgrade on_chat_model_start from INFO to DEBUG, log only metadata (batch_count, message_counts) instead of full serialized/messages content

feat(persistence): per-user filesystem isolation, run-scoped APIs, and state/history simplification (#2153)
* feat(persistence): add unified persistence layer with event store, token tracking, and feedback (#1930) * feat(persistence): add SQLAlchemy 2.0 async ORM scaffold Introduce a unified database configuration (DatabaseConfig) that controls both the LangGraph checkpointer and the DeerFlow application persistence layer from a single `database:` config section. New modules: - deerflow.config.database_config — Pydantic config with memory/sqlite/postgres backends - deerflow.persistence — async engine lifecycle, DeclarativeBase with to_dict mixin, Alembic skeleton - deerflow.runtime.runs.store — RunStore ABC + MemoryRunStore implementation Gateway integration initializes/tears down the persistence engine in the existing langgraph_runtime() context manager. Legacy checkpointer config is preserved for backward compatibility. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add RunEventStore ABC + MemoryRunEventStore Phase 2-A prerequisite for event storage: adds the unified run event stream interface (RunEventStore) with an in-memory implementation, RunEventsConfig, gateway integration, and comprehensive tests (27 cases). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add ORM models, repositories, DB/JSONL event stores, RunJournal, and API endpoints Phase 2-B: run persistence + event storage + token tracking. - ORM models: RunRow (with token fields), ThreadMetaRow, RunEventRow - RunRepository implements RunStore ABC via SQLAlchemy ORM - ThreadMetaRepository with owner access control - DbRunEventStore with trace content truncation and cursor pagination - JsonlRunEventStore with per-run files and seq recovery from disk - RunJournal (BaseCallbackHandler) captures LLM/tool/lifecycle events, accumulates token usage by caller type, buffers and flushes to store - RunManager now accepts optional RunStore for persistent backing - Worker creates RunJournal, writes human_message, injects callbacks - Gateway deps use factory functions (RunRepository when DB available) - New endpoints: messages, run messages, run events, token-usage - ThreadCreateRequest gains assistant_id field - 92 tests pass (33 new), zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add user feedback + follow-up run association Phase 2-C: feedback and follow-up tracking. - FeedbackRow ORM model (rating +1/-1, optional message_id, comment) - FeedbackRepository with CRUD, list_by_run/thread, aggregate stats - Feedback API endpoints: create, list, stats, delete - follow_up_to_run_id in RunCreateRequest (explicit or auto-detected from latest successful run on the thread) - Worker writes follow_up_to_run_id into human_message event metadata - Gateway deps: feedback_repo factory + getter - 17 new tests (14 FeedbackRepository + 3 follow-up association) - 109 total tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test+config: comprehensive Phase 2 test coverage + deprecate checkpointer config - config.example.yaml: deprecate standalone checkpointer section, activate unified database:sqlite as default (drives both checkpointer + app data) - New: test_thread_meta_repo.py (14 tests) — full ThreadMetaRepository coverage including check_access owner logic, list_by_owner pagination - Extended test_run_repository.py (+4 tests) — completion preserves fields, list ordering desc, limit, owner_none returns all - Extended test_run_journal.py (+8 tests) — on_chain_error, track_tokens=false, middleware no ai_message, unknown caller tokens, convenience fields, tool_error, non-summarization custom event - Extended test_run_event_store.py (+7 tests) — DB batch seq continuity, make_run_event_store factory (memory/db/jsonl/fallback/unknown) - Extended test_phase2b_integration.py (+4 tests) — create_or_reject persists, follow-up metadata, summarization in history, full DB-backed lifecycle - Fixed DB integration test to use proper fake objects (not MagicMock) for JSON-serializable metadata - 157 total Phase 2 tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * config: move default sqlite_dir to .deer-flow/data Keep SQLite databases alongside other DeerFlow-managed data (threads, memory) under the .deer-flow/ directory instead of a top-level ./data folder. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(persistence): remove UTFJSON, use engine-level json_serializer + datetime.now() - Replace custom UTFJSON type with standard sqlalchemy.JSON in all ORM models. Add json_serializer=json.dumps(ensure_ascii=False) to all create_async_engine calls so non-ASCII text (Chinese etc.) is stored as-is in both SQLite and Postgres. - Change ORM datetime defaults from datetime.now(UTC) to datetime.now(), remove UTC imports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): simplify deps.py with getter factory + inline repos - Replace 6 identical getter functions with _require() factory. - Inline 3 _make_*_repo() factories into langgraph_runtime(), call get_session_factory() once instead of 3 times. - Add thread_meta upsert in start_run (services.py). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(docker): add UV_EXTRAS build arg for optional dependencies Support installing optional dependency groups (e.g. postgres) at Docker build time via UV_EXTRAS build arg: UV_EXTRAS=postgres docker compose build Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(journal): fix flush, token tracking, and consolidate tests RunJournal fixes: - _flush_sync: retain events in buffer when no event loop instead of dropping them; worker's finally block flushes via async flush(). - on_llm_end: add tool_calls filter and caller=="lead_agent" guard for ai_message events; mark message IDs for dedup with record_llm_usage. - worker.py: persist completion data (tokens, message count) to RunStore in finally block. Model factory: - Auto-inject stream_usage=True for BaseChatOpenAI subclasses with custom api_base, so usage_metadata is populated in streaming responses. Test consolidation: - Delete test_phase2b_integration.py (redundant with existing tests). - Move DB-backed lifecycle test into test_run_journal.py. - Add tests for stream_usage injection in test_model_factory.py. - Clean up executor/task_tool dead journal references. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): widen content type to str|dict in all store backends Allow event content to be a dict (for structured OpenAI-format messages) in addition to plain strings. Dict values are JSON-serialized for the DB backend and deserialized on read; memory and JSONL backends handle dicts natively. Trace truncation now serializes dicts to JSON before measuring. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(events): use metadata flag instead of heuristic for dict content detection Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(converters): add LangChain-to-OpenAI message format converters Pure functions langchain_to_openai_message, langchain_to_openai_completion, langchain_messages_to_openai, and _infer_finish_reason for converting LangChain BaseMessage objects to OpenAI Chat Completions format, used by RunJournal for event storage. 15 unit tests added. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(converters): handle empty list content as null, clean up test Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): human_message content uses OpenAI user message format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): ai_message uses OpenAI format, add ai_tool_call message event - ai_message content now uses {"role": "assistant", "content": "..."} format - New ai_tool_call message event emitted when lead_agent LLM responds with tool_calls - ai_tool_call uses langchain_to_openai_message converter for consistent format - Both events include finish_reason in metadata ("stop" or "tool_calls") Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add tool_result message event with OpenAI tool message format Cache tool_call_id from on_tool_start keyed by run_id as fallback for on_tool_end, then emit a tool_result message event (role=tool, tool_call_id, content) after each successful tool completion. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): summary content uses OpenAI system message format Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): replace llm_start/llm_end with llm_request/llm_response in OpenAI format Add on_chat_model_start to capture structured prompt messages as llm_request events. Replace llm_end trace events with llm_response using OpenAI Chat Completions format. Track llm_call_index to pair request/response events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add record_middleware method for middleware trace events Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test(events): add full run sequence integration test for OpenAI content format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): align message events with checkpoint format and add middleware tag injection - Message events (ai_message, ai_tool_call, tool_result, human_message) now use BaseMessage.model_dump() format, matching LangGraph checkpoint values.messages - on_tool_end extracts tool_call_id/name/status from ToolMessage objects - on_tool_error now emits tool_result message events with error status - record_middleware uses middleware:{tag} event_type and middleware category - Summarization custom events use middleware:summarize category - TitleMiddleware injects middleware:title tag via get_config() inheritance - SummarizationMiddleware model bound with middleware:summarize tag - Worker writes human_message using HumanMessage.model_dump() Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): switch search endpoint to threads_meta table and sync title - POST /api/threads/search now queries threads_meta table directly, removing the two-phase Store + Checkpointer scan approach - Add ThreadMetaRepository.search() with metadata/status filters - Add ThreadMetaRepository.update_display_name() for title sync - Worker syncs checkpoint title to threads_meta.display_name on run completion - Map display_name to values.title in search response for API compatibility Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): history endpoint reads messages from event store - POST /api/threads/{thread_id}/history now combines two data sources: checkpointer for checkpoint_id, metadata, title, thread_data; event store for messages (complete history, not truncated by summarization) - Strip internal LangGraph metadata keys from response - Remove full channel_values serialization in favor of selective fields Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: remove duplicate optional-dependencies header in pyproject.toml Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(middleware): pass tagged config to TitleMiddleware ainvoke call Without the config, the middleware:title tag was not injected, causing the LLM response to be recorded as a lead_agent ai_message in run_events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve merge conflict in .env.example Keep both DATABASE_URL (from persistence-scaffold) and WECOM credentials (from main) after the merge. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address review feedback on PR #1851 - Fix naive datetime.now() → datetime.now(UTC) in all ORM models - Fix seq race condition in DbRunEventStore.put() with FOR UPDATE and UNIQUE(thread_id, seq) constraint - Encapsulate _store access in RunManager.update_run_completion() - Deduplicate _store.put() logic in RunManager via _persist_to_store() - Add update_run_completion to RunStore ABC + MemoryRunStore - Wire follow_up_to_run_id through the full create path - Add error recovery to RunJournal._flush_sync() lost-event scenario - Add migration note for search_threads breaking change - Fix test_checkpointer_none_fix mock to set database=None Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: update uv.lock Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address 22 review comments from CodeQL, Copilot, and Code Quality Bug fixes: - Sanitize log params to prevent log injection (CodeQL) - Reset threads_meta.status to idle/error when run completes - Attach messages only to latest checkpoint in /history response - Write threads_meta on POST /threads so new threads appear in search Lint fixes: - Remove unused imports (journal.py, migrations/env.py, test_converters.py) - Convert lambda to named function (engine.py, Ruff E731) - Remove unused logger definitions in repos (Ruff F841) - Add logging to JSONL decode errors and empty except blocks - Separate assert side-effects in tests (CodeQL) - Remove unused local variables in tests (Ruff F841) - Fix max_trace_content truncation to use byte length, not char length Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * style: apply ruff format to persistence and runtime files Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Potential fix for pull request finding 'Statement has no effect' Co-authored-by: Copilot Autofix powered by AI <223894421+github-code-quality[bot]@users.noreply.github.com> * refactor(runtime): introduce RunContext to reduce run_agent parameter bloat Extract checkpointer, store, event_store, run_events_config, thread_meta_repo, and follow_up_to_run_id into a frozen RunContext dataclass. Add get_run_context() in deps.py to build the base context from app.state singletons. start_run() uses dataclasses.replace() to enrich per-run fields before passing ctx to run_agent. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): move sanitize_log_param to app/gateway/utils.py Extract the log-injection sanitizer from routers/threads.py into a shared utils module and rename to sanitize_log_param (public API). Eliminates the reverse service → router import in services.py. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * perf: use SQL aggregation for feedback stats and thread token usage Replace Python-side counting in FeedbackRepository.aggregate_by_run with a single SELECT COUNT/SUM query. Add RunStore.aggregate_tokens_by_thread abstract method with SQL GROUP BY implementation in RunRepository and Python fallback in MemoryRunStore. Simplify the thread_token_usage endpoint to delegate to the new method, eliminating the limit=10000 truncation risk.

feat(persistence):Unified persistence layer with event store, feedback, and rebase cleanup (#2134)
* feat(persistence): add unified persistence layer with event store, token tracking, and feedback (#1930) * feat(persistence): add SQLAlchemy 2.0 async ORM scaffold Introduce a unified database configuration (DatabaseConfig) that controls both the LangGraph checkpointer and the DeerFlow application persistence layer from a single `database:` config section. New modules: - deerflow.config.database_config — Pydantic config with memory/sqlite/postgres backends - deerflow.persistence — async engine lifecycle, DeclarativeBase with to_dict mixin, Alembic skeleton - deerflow.runtime.runs.store — RunStore ABC + MemoryRunStore implementation Gateway integration initializes/tears down the persistence engine in the existing langgraph_runtime() context manager. Legacy checkpointer config is preserved for backward compatibility. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add RunEventStore ABC + MemoryRunEventStore Phase 2-A prerequisite for event storage: adds the unified run event stream interface (RunEventStore) with an in-memory implementation, RunEventsConfig, gateway integration, and comprehensive tests (27 cases). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add ORM models, repositories, DB/JSONL event stores, RunJournal, and API endpoints Phase 2-B: run persistence + event storage + token tracking. - ORM models: RunRow (with token fields), ThreadMetaRow, RunEventRow - RunRepository implements RunStore ABC via SQLAlchemy ORM - ThreadMetaRepository with owner access control - DbRunEventStore with trace content truncation and cursor pagination - JsonlRunEventStore with per-run files and seq recovery from disk - RunJournal (BaseCallbackHandler) captures LLM/tool/lifecycle events, accumulates token usage by caller type, buffers and flushes to store - RunManager now accepts optional RunStore for persistent backing - Worker creates RunJournal, writes human_message, injects callbacks - Gateway deps use factory functions (RunRepository when DB available) - New endpoints: messages, run messages, run events, token-usage - ThreadCreateRequest gains assistant_id field - 92 tests pass (33 new), zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add user feedback + follow-up run association Phase 2-C: feedback and follow-up tracking. - FeedbackRow ORM model (rating +1/-1, optional message_id, comment) - FeedbackRepository with CRUD, list_by_run/thread, aggregate stats - Feedback API endpoints: create, list, stats, delete - follow_up_to_run_id in RunCreateRequest (explicit or auto-detected from latest successful run on the thread) - Worker writes follow_up_to_run_id into human_message event metadata - Gateway deps: feedback_repo factory + getter - 17 new tests (14 FeedbackRepository + 3 follow-up association) - 109 total tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test+config: comprehensive Phase 2 test coverage + deprecate checkpointer config - config.example.yaml: deprecate standalone checkpointer section, activate unified database:sqlite as default (drives both checkpointer + app data) - New: test_thread_meta_repo.py (14 tests) — full ThreadMetaRepository coverage including check_access owner logic, list_by_owner pagination - Extended test_run_repository.py (+4 tests) — completion preserves fields, list ordering desc, limit, owner_none returns all - Extended test_run_journal.py (+8 tests) — on_chain_error, track_tokens=false, middleware no ai_message, unknown caller tokens, convenience fields, tool_error, non-summarization custom event - Extended test_run_event_store.py (+7 tests) — DB batch seq continuity, make_run_event_store factory (memory/db/jsonl/fallback/unknown) - Extended test_phase2b_integration.py (+4 tests) — create_or_reject persists, follow-up metadata, summarization in history, full DB-backed lifecycle - Fixed DB integration test to use proper fake objects (not MagicMock) for JSON-serializable metadata - 157 total Phase 2 tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * config: move default sqlite_dir to .deer-flow/data Keep SQLite databases alongside other DeerFlow-managed data (threads, memory) under the .deer-flow/ directory instead of a top-level ./data folder. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(persistence): remove UTFJSON, use engine-level json_serializer + datetime.now() - Replace custom UTFJSON type with standard sqlalchemy.JSON in all ORM models. Add json_serializer=json.dumps(ensure_ascii=False) to all create_async_engine calls so non-ASCII text (Chinese etc.) is stored as-is in both SQLite and Postgres. - Change ORM datetime defaults from datetime.now(UTC) to datetime.now(), remove UTC imports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): simplify deps.py with getter factory + inline repos - Replace 6 identical getter functions with _require() factory. - Inline 3 _make_*_repo() factories into langgraph_runtime(), call get_session_factory() once instead of 3 times. - Add thread_meta upsert in start_run (services.py). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(docker): add UV_EXTRAS build arg for optional dependencies Support installing optional dependency groups (e.g. postgres) at Docker build time via UV_EXTRAS build arg: UV_EXTRAS=postgres docker compose build Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(journal): fix flush, token tracking, and consolidate tests RunJournal fixes: - _flush_sync: retain events in buffer when no event loop instead of dropping them; worker's finally block flushes via async flush(). - on_llm_end: add tool_calls filter and caller=="lead_agent" guard for ai_message events; mark message IDs for dedup with record_llm_usage. - worker.py: persist completion data (tokens, message count) to RunStore in finally block. Model factory: - Auto-inject stream_usage=True for BaseChatOpenAI subclasses with custom api_base, so usage_metadata is populated in streaming responses. Test consolidation: - Delete test_phase2b_integration.py (redundant with existing tests). - Move DB-backed lifecycle test into test_run_journal.py. - Add tests for stream_usage injection in test_model_factory.py. - Clean up executor/task_tool dead journal references. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): widen content type to str|dict in all store backends Allow event content to be a dict (for structured OpenAI-format messages) in addition to plain strings. Dict values are JSON-serialized for the DB backend and deserialized on read; memory and JSONL backends handle dicts natively. Trace truncation now serializes dicts to JSON before measuring. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(events): use metadata flag instead of heuristic for dict content detection Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(converters): add LangChain-to-OpenAI message format converters Pure functions langchain_to_openai_message, langchain_to_openai_completion, langchain_messages_to_openai, and _infer_finish_reason for converting LangChain BaseMessage objects to OpenAI Chat Completions format, used by RunJournal for event storage. 15 unit tests added. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(converters): handle empty list content as null, clean up test Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): human_message content uses OpenAI user message format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): ai_message uses OpenAI format, add ai_tool_call message event - ai_message content now uses {"role": "assistant", "content": "..."} format - New ai_tool_call message event emitted when lead_agent LLM responds with tool_calls - ai_tool_call uses langchain_to_openai_message converter for consistent format - Both events include finish_reason in metadata ("stop" or "tool_calls") Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add tool_result message event with OpenAI tool message format Cache tool_call_id from on_tool_start keyed by run_id as fallback for on_tool_end, then emit a tool_result message event (role=tool, tool_call_id, content) after each successful tool completion. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): summary content uses OpenAI system message format Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): replace llm_start/llm_end with llm_request/llm_response in OpenAI format Add on_chat_model_start to capture structured prompt messages as llm_request events. Replace llm_end trace events with llm_response using OpenAI Chat Completions format. Track llm_call_index to pair request/response events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add record_middleware method for middleware trace events Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test(events): add full run sequence integration test for OpenAI content format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): align message events with checkpoint format and add middleware tag injection - Message events (ai_message, ai_tool_call, tool_result, human_message) now use BaseMessage.model_dump() format, matching LangGraph checkpoint values.messages - on_tool_end extracts tool_call_id/name/status from ToolMessage objects - on_tool_error now emits tool_result message events with error status - record_middleware uses middleware:{tag} event_type and middleware category - Summarization custom events use middleware:summarize category - TitleMiddleware injects middleware:title tag via get_config() inheritance - SummarizationMiddleware model bound with middleware:summarize tag - Worker writes human_message using HumanMessage.model_dump() Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): switch search endpoint to threads_meta table and sync title - POST /api/threads/search now queries threads_meta table directly, removing the two-phase Store + Checkpointer scan approach - Add ThreadMetaRepository.search() with metadata/status filters - Add ThreadMetaRepository.update_display_name() for title sync - Worker syncs checkpoint title to threads_meta.display_name on run completion - Map display_name to values.title in search response for API compatibility Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): history endpoint reads messages from event store - POST /api/threads/{thread_id}/history now combines two data sources: checkpointer for checkpoint_id, metadata, title, thread_data; event store for messages (complete history, not truncated by summarization) - Strip internal LangGraph metadata keys from response - Remove full channel_values serialization in favor of selective fields Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: remove duplicate optional-dependencies header in pyproject.toml Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(middleware): pass tagged config to TitleMiddleware ainvoke call Without the config, the middleware:title tag was not injected, causing the LLM response to be recorded as a lead_agent ai_message in run_events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve merge conflict in .env.example Keep both DATABASE_URL (from persistence-scaffold) and WECOM credentials (from main) after the merge. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address review feedback on PR #1851 - Fix naive datetime.now() → datetime.now(UTC) in all ORM models - Fix seq race condition in DbRunEventStore.put() with FOR UPDATE and UNIQUE(thread_id, seq) constraint - Encapsulate _store access in RunManager.update_run_completion() - Deduplicate _store.put() logic in RunManager via _persist_to_store() - Add update_run_completion to RunStore ABC + MemoryRunStore - Wire follow_up_to_run_id through the full create path - Add error recovery to RunJournal._flush_sync() lost-event scenario - Add migration note for search_threads breaking change - Fix test_checkpointer_none_fix mock to set database=None Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: update uv.lock Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address 22 review comments from CodeQL, Copilot, and Code Quality Bug fixes: - Sanitize log params to prevent log injection (CodeQL) - Reset threads_meta.status to idle/error when run completes - Attach messages only to latest checkpoint in /history response - Write threads_meta on POST /threads so new threads appear in search Lint fixes: - Remove unused imports (journal.py, migrations/env.py, test_converters.py) - Convert lambda to named function (engine.py, Ruff E731) - Remove unused logger definitions in repos (Ruff F841) - Add logging to JSONL decode errors and empty except blocks - Separate assert side-effects in tests (CodeQL) - Remove unused local variables in tests (Ruff F841) - Fix max_trace_content truncation to use byte length, not char length Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * style: apply ruff format to persistence and runtime files Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Potential fix for pull request finding 'Statement has no effect' Co-authored-by: Copilot Autofix powered by AI <223894421+github-code-quality[bot]@users.noreply.github.com> * refactor(runtime): introduce RunContext to reduce run_agent parameter bloat Extract checkpointer, store, event_store, run_events_config, thread_meta_repo, and follow_up_to_run_id into a frozen RunContext dataclass. Add get_run_context() in deps.py to build the base context from app.state singletons. start_run() uses dataclasses.replace() to enrich per-run fields before passing ctx to run_agent. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): move sanitize_log_param to app/gateway/utils.py Extract the log-injection sanitizer from routers/threads.py into a shared utils module and rename to sanitize_log_param (public API). Eliminates the reverse service → router import in services.py. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * perf: use SQL aggregation for feedback stats and thread token usage Replace Python-side counting in FeedbackRepository.aggregate_by_run with a single SELECT COUNT/SUM query. Add RunStore.aggregate_tokens_by_thread abstract method with SQL GROUP BY implementation in RunRepository and Python fallback in MemoryRunStore. Simplify the thread_token_usage endpoint to delegate to the new method, eliminating the limit=10000 truncation risk. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: annotate DbRunEventStore.put() as low-frequency path Add docstring clarifying that put() opens a per-call transaction with FOR UPDATE and should only be used for infrequent writes (currently just the initial human_message event). High-throughput callers should use put_batch() instead. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(threads): fall back to Store search when ThreadMetaRepository is unavailable When database.backend=memory (default) or no SQL session factory is configured, search_threads now queries the LangGraph Store instead of returning 503.

Dict values are JSON-serialized for the DB backend and deserialized on read; memory and JSONL backends handle dicts natively. Trace truncation now serializes dicts to JSON before measuring.

feat(auth): release-validation pass for 2.0-rc — 12 blockers + simplify follow-ups (#2008)
* feat(auth): introduce backend auth module Port RFC-001 authentication core from PR #1728: - JWT token handling (create_access_token, decode_token, TokenPayload) - Password hashing (bcrypt) with verify_password - SQLite UserRepository with base interface - Provider Factory pattern (LocalAuthProvider) - CLI reset_admin tool - Auth-specific errors (AuthErrorCode, TokenError, AuthErrorResponse) Deps: - bcrypt>=4.0.0 - pyjwt>=2.9.0 - email-validator>=2.0.0 - backend/uv.toml pins public PyPI index Tests: 12 pure unit tests (test_auth_config.py, test_auth_errors.py). Scope note: authz.py, test_auth.py, and test_auth_type_system.py are deferred to commit 2 because they depend on middleware and deps wiring that is not yet in place. Commit 1 stays "pure new files only" as the spec mandates. * feat(auth): wire auth end-to-end (middleware + frontend replacement) Backend: - Port auth_middleware, csrf_middleware, langgraph_auth, routers/auth - Port authz decorator (owner_filter_key defaults to 'owner_id') - Merge app.py: register AuthMiddleware + CSRFMiddleware + CORS, add _ensure_admin_user lifespan hook, _migrate_orphaned_threads helper, register auth router - Merge deps.py: add get_local_provider, get_current_user_from_request, get_optional_user_from_request; keep get_current_user as thin str|None adapter for feedback router - langgraph.json: add auth path pointing to langgraph_auth.py:auth - Rename metadata['user_id'] -> metadata['owner_id'] in langgraph_auth (both metadata write and LangGraph filter dict) + test fixtures Frontend: - Delete better-auth library and api catch-all route - Remove better-auth npm dependency and env vars (BETTER_AUTH_SECRET, BETTER_AUTH_GITHUB_*) from env.js - Port frontend/src/core/auth/* (AuthProvider, gateway-config, proxy-policy, server-side getServerSideUser, types) - Port frontend/src/core/api/fetcher.ts - Port (auth)/layout, (auth)/login, (auth)/setup pages - Rewrite workspace/layout.tsx as server component that calls getServerSideUser and wraps in AuthProvider - Port workspace/workspace-content.tsx for the client-side sidebar logic Tests: - Port 5 auth test files (test_auth, test_auth_middleware, test_auth_type_system, test_ensure_admin, test_langgraph_auth) - 176 auth tests PASS After this commit: login/logout/registration flow works, but persistence layer does not yet filter by owner_id. Commit 4 closes that gap. * feat(auth): account settings page + i18n - Port account-settings-page.tsx (change password, change email, logout) - Wire into settings-dialog.tsx as new "account" section with UserIcon, rendered first in the section list - Add i18n keys: - en-US/zh-CN: settings.sections.account ("Account" / "账号") - en-US/zh-CN: button.logout ("Log out" / "退出登录") - types.ts: matching type declarations * feat(auth): enforce owner_id across 2.0-rc persistence layer Add request-scoped contextvar-based owner filtering to threads_meta, runs, run_events, and feedback repositories. Router code is unchanged — isolation is enforced at the storage layer so that any caller that forgets to pass owner_id still gets filtered results, and new routes cannot accidentally leak data. Core infrastructure ------------------- - deerflow/runtime/user_context.py (new): - ContextVar[CurrentUser | None] with default None - runtime_checkable CurrentUser Protocol (structural subtype with .id) - set/reset/get/require helpers - AUTO sentinel + resolve_owner_id(value, method_name) for sentinel three-state resolution: AUTO reads contextvar, explicit str overrides, explicit None bypasses the filter (for migration/CLI) Repository changes ------------------ - ThreadMetaRepository: create/get/search/update_*/delete gain owner_id=AUTO kwarg; read paths filter by owner, writes stamp it, mutations check ownership before applying - RunRepository: put/get/list_by_thread/delete gain owner_id=AUTO kwarg - FeedbackRepository: create/get/list_by_run/list_by_thread/delete gain owner_id=AUTO kwarg - DbRunEventStore: list_messages/list_events/list_messages_by_run/ count_messages/delete_by_thread/delete_by_run gain owner_id=AUTO kwarg. Write paths (put/put_batch) read contextvar softly: when a request-scoped user is available, owner_id is stamped; background worker writes without a user context pass None which is valid (orphan row to be bound by migration) Schema ------ - persistence/models/run_event.py: RunEventRow.owner_id = Mapped[ str | None] = mapped_column(String(64), nullable=True, index=True) - No alembic migration needed: 2.0 ships fresh, Base.metadata.create_all picks up the new column automatically Middleware ---------- - auth_middleware.py: after cookie check, call get_optional_user_from_ request to load the real User, stamp it into request.state.user AND the contextvar via set_current_user, reset in a try/finally. Public paths and unauthenticated requests continue without contextvar, and @require_auth handles the strict 401 path Test infrastructure ------------------- - tests/conftest.py: @pytest.fixture(autouse=True) _auto_user_context sets a default SimpleNamespace(id="test-user-autouse") on every test unless marked @pytest.mark.no_auto_user. Keeps existing 20+ persistence tests passing without modification - pyproject.toml [tool.pytest.ini_options]: register no_auto_user marker so pytest does not emit warnings for opt-out tests - tests/test_user_context.py: 6 tests covering three-state semantics, Protocol duck typing, and require/optional APIs - tests/test_thread_meta_repo.py: one test updated to pass owner_id= None explicitly where it was previously relying on the old default Test results ------------ - test_user_context.py: 6 passed - test_auth*.py + test_langgraph_auth.py + test_ensure_admin.py: 127 - test_run_event_store / test_run_repository / test_thread_meta_repo / test_feedback: 92 passed - Full backend suite: 1905 passed, 2 failed (both @requires_llm flaky integration tests unrelated to auth), 1 skipped * feat(auth): extend orphan migration to 2.0-rc persistence tables _ensure_admin_user now runs a three-step pipeline on every boot: Step 1 (fatal): admin user exists / is created / password is reset Step 2 (non-fatal): LangGraph store orphan threads → admin Step 3 (non-fatal): SQL persistence tables → admin - threads_meta - runs - run_events - feedback Each step is idempotent. The fatal/non-fatal split mirrors PR #1728's original philosophy: admin creation failure blocks startup (the system is unusable without an admin), whereas migration failures log a warning and let the service proceed (a partial migration is recoverable; a missing admin is not). Key helpers ----------- - _iter_store_items(store, namespace, *, page_size=500): async generator that cursor-paginates across LangGraph store pages. Fixes PR #1728's hardcoded limit=1000 bug that would silently lose orphans beyond the first page. - _migrate_orphaned_threads(store, admin_user_id): Rewritten to use _iter_store_items. Returns the migrated count so the caller can log it; raises only on unhandled exceptions. - _migrate_orphan_sql_tables(admin_user_id): Imports the 4 ORM models lazily, grabs the shared session factory, runs one UPDATE per table in a single transaction, commits once. No-op when no persistence backend is configured (in-memory dev). Tests: test_ensure_admin.py (8 passed) * test(auth): port AUTH test plan docs + lint/format pass - Port backend/docs/AUTH_TEST_PLAN.md and AUTH_UPGRADE.md from PR #1728 - Rename metadata.user_id → metadata.owner_id in AUTH_TEST_PLAN.md (4 occurrences from the original PR doc) - ruff auto-fix UP037 in sentinel type annotations: drop quotes around "str | None | _AutoSentinel" now that from __future__ import annotations makes them implicit string forms - ruff format: 2 files (app/gateway/app.py, runtime/user_context.py) Note on test coverage additions: - conftest.py autouse fixture was already added in commit 4 (had to be co-located with the repository changes to keep pre-existing persistence tests passing) - cross-user isolation E2E tests (test_owner_isolation.py) deferred — enforcement is already proven by the 98-test repository suite via the autouse fixture + explicit _AUTO sentinel exercises - New test cases (TC-API-17..20, TC-ATK-13, TC-MIG-01..07) listed in AUTH_TEST_PLAN.md are deferred to a follow-up PR — they are manual-QA test cases rather than pytest code, and the spec-level coverage is already met by test_user_context.py + the 98-test repository suite. Final test results: - Auth suite (test_auth*, test_langgraph_auth, test_ensure_admin, test_user_context): 186 passed - Persistence suite (test_run_event_store, test_run_repository, test_thread_meta_repo, test_feedback): 98 passed - Lint: ruff check + ruff format both clean * test(auth): add cross-user isolation test suite 10 tests exercising the storage-layer owner filter by manually switching the user_context contextvar between two users. Verifies the safety invariant: After a repository write with owner_id=A, a subsequent read with owner_id=B must not return the row, and vice versa. Covers all 4 tables that own user-scoped data: TC-API-17 threads_meta — read, search, update, delete cross-user TC-API-18 runs — get, list_by_thread, delete cross-user TC-API-19 run_events — list_messages, list_events, count_messages, delete_by_thread (CRITICAL: raw conversation content leak vector) TC-API-20 feedback — get, list_by_run, delete cross-user Plus two meta-tests verifying the sentinel pattern itself: - AUTO + unset contextvar raises RuntimeError - explicit owner_id=None bypasses the filter (migration escape hatch) Architecture note ----------------- These tests bypass the HTTP layer by design. The full chain (cookie → middleware → contextvar → repository) is covered piecewise: - test_auth_middleware.py: middleware sets contextvar from cookies - test_owner_isolation.py: repositories enforce isolation when contextvar is set to different users Together they prove the end-to-end safety property without the ceremony of spinning up a full TestClient + in-memory DB for every router endpoint. Tests pass: 231 (full auth + persistence + isolation suite) Lint: clean * refactor(auth): migrate user repository to SQLAlchemy ORM Move the users table into the shared persistence engine so auth matches the pattern of threads_meta, runs, run_events, and feedback — one engine, one session factory, one schema init codepath. New files --------- - persistence/user/__init__.py, persistence/user/model.py: UserRow ORM class with partial unique index on (oauth_provider, oauth_id) - Registered in persistence/models/__init__.py so Base.metadata.create_all() picks it up Modified -------- - auth/repositories/sqlite.py: rewritten as async SQLAlchemy, identical constructor pattern to the other four repositories (def __init__(self, session_factory) + self._sf = session_factory) - auth/config.py: drop users_db_path field — storage is configured through config.database like every other table - deps.py/get_local_provider: construct SQLiteUserRepository with the shared session factory, fail fast if engine is not initialised - tests/test_auth.py: rewrite test_sqlite_round_trip_new_fields to use the shared engine (init_engine + close_engine in a tempdir) - tests/test_auth_type_system.py: add per-test autouse fixture that spins up a scratch engine and resets deps._cached_* singletons * refactor(auth): remove SQL orphan migration (unused in supported scenarios) The _migrate_orphan_sql_tables helper existed to bind NULL owner_id rows in threads_meta, runs, run_events, and feedback to the admin on first boot. But in every supported upgrade path, it's a no-op: 1. Fresh install: create_all builds fresh tables, no legacy rows 2. No-auth → with-auth (no existing persistence DB): persistence tables are created fresh by create_all, no legacy rows 3. No-auth → with-auth (has existing persistence DB from #1930): NOT a supported upgrade path — "有 DB 到有 DB" schema evolution is out of scope; users wipe DB or run manual ALTER So the SQL orphan migration never has anything to do in the supported matrix. Delete the function, simplify _ensure_admin_user from a 3-step pipeline to a 2-step one (admin creation + LangGraph store orphan migration only). LangGraph store orphan migration stays: it serves the real "no-auth → with-auth" upgrade path where a user's existing LangGraph thread metadata has no owner_id field and needs to be stamped with the newly-created admin's id. Tests: 284 passed (auth + persistence + isolation) Lint: clean * security(auth): write initial admin password to 0600 file instead of logs CodeQL py/clear-text-logging-sensitive-data flagged 3 call sites that logged the auto-generated admin password to stdout via logger.info(). Production log aggregators (ELK/Splunk/etc) would have captured those cleartext secrets. Replace with a shared helper that writes to .deer-flow/admin_initial_credentials.txt with mode 0600, and log only the path. New file -------- - app/gateway/auth/credential_file.py: write_initial_credentials() helper. Takes email, password, and a "initial"/"reset" label. Creates .deer-flow/ if missing, writes a header comment plus the email+password, chmods 0o600, returns the absolute Path. Modified -------- - app/gateway/app.py: both _ensure_admin_user paths (fresh creation + needs_setup password reset) now write to file and log the path - app/gateway/auth/reset_admin.py: rewritten to use the shared ORM repo (SQLiteUserRepository with session_factory) and the credential_file helper. The previous implementation was broken after the earlier ORM refactor — it still imported _get_users_conn and constructed SQLiteUserRepository() without a session factory. No tests changed — the three password-log sites are all exercised via existing test_ensure_admin.py which checks that startup succeeds, not that a specific string appears in logs. CodeQL alerts 272, 283, 284: all resolved. * security(auth): strict JWT validation in middleware (fix junk cookie bypass) AUTH_TEST_PLAN test 7.5.8 expects junk cookies to be rejected with 401. The previous middleware behaviour was "presence-only": check that some access_token cookie exists, then pass through. In combination with my Task-12 decision to skip @require_auth decorators on routes, this created a gap where a request with any cookie-shaped string (e.g. access_token=not-a-jwt) would bypass authentication on routes that do not touch the repository (/api/models, /api/mcp/config, /api/memory, /api/skills, …). Fix: middleware now calls get_current_user_from_request() strictly and catches the resulting HTTPException to render a 401 with the proper fine-grained error code (token_invalid, token_expired, user_not_found, …). On success it stamps request.state.user and the contextvar so repository-layer owner filters work downstream. The 4 old "_with_cookie_passes" tests in test_auth_middleware.py were written for the presence-only behaviour; they asserted that a junk cookie would make the handler return 200. They are renamed to "_with_junk_cookie_rejected" and their assertions flipped to 401. The negative path (no cookie → 401 not_authenticated) is unchanged. Verified: no cookie → 401 not_authenticated junk cookie → 401 token_invalid (the fixed bug) expired cookie → 401 token_expired Tests: 284 passed (auth + persistence + isolation) Lint: clean * security(auth): wire @require_permission(owner_check=True) on isolation routes Apply the require_permission decorator to all 28 routes that take a {thread_id} path parameter. Combined with the strict middleware (previous commit), this gives the double-layer protection that AUTH_TEST_PLAN test 7.5.9 documents: Layer 1 (AuthMiddleware): cookie + JWT validation, rejects junk cookies and stamps request.state.user Layer 2 (@require_permission with owner_check=True): per-resource ownership verification via ThreadMetaStore.check_access — returns 404 if a different user owns the thread The decorator's owner_check branch is rewritten to use the SQL thread_meta_repo (the 2.0-rc persistence layer) instead of the LangGraph store path that PR #1728 used (_store_get / get_store in routers/threads.py). The inject_record convenience is dropped — no caller in 2.0 needs the LangGraph blob, and the SQL repo has a different shape. Routes decorated (28 total): - threads.py: delete, patch, get, get-state, post-state, post-history - thread_runs.py: post-runs, post-runs-stream, post-runs-wait, list_runs, get_run, cancel_run, join_run, stream_existing_run, list_thread_messages, list_run_messages, list_run_events, thread_token_usage - feedback.py: create, list, stats, delete - uploads.py: upload (added Request param), list, delete - artifacts.py: get_artifact - suggestions.py: generate (renamed body parameter to avoid conflict with FastAPI Request) Test fixes: - test_suggestions_router.py: bypass the decorator via __wrapped__ (the unit tests cover parsing logic, not auth — no point spinning up a thread_meta_repo just to test JSON unwrapping) - test_auth_middleware.py 4 fake-cookie tests: already updated in the previous commit (745bf432) Tests: 293 passed (auth + persistence + isolation + suggestions) Lint: clean * security(auth): defense-in-depth fixes from release validation pass Eight findings caught while running the AUTH_TEST_PLAN end-to-end against the deployed sg_dev stack. Each is a pre-condition for shipping release/2.0-rc that the previous PRs missed. Backend hardening - routers/auth.py: rate limiter X-Real-IP now requires AUTH_TRUSTED_PROXIES whitelist (CIDR/IP allowlist). Without nginx in front, the previous code honored arbitrary X-Real-IP, letting an attacker rotate the header to fully bypass the per-IP login lockout. - routers/auth.py: 36-entry common-password blocklist via Pydantic field_validator on RegisterRequest + ChangePasswordRequest. The shared _validate_strong_password helper keeps the constraint in one place. - routers/threads.py: ThreadCreateRequest + ThreadPatchRequest strip server-reserved metadata keys (owner_id, user_id) via Pydantic field_validator so a forged value can never round-trip back to other clients reading the same thread. The actual ownership invariant stays on the threads_meta row; this closes the metadata-blob echo gap. - authz.py + thread_meta/sql.py: require_permission gains a require_existing flag plumbed through check_access(require_existing=True). Destructive routes (DELETE/PATCH/state-update/runs/feedback) now treat a missing thread_meta row as 404 instead of "untracked legacy thread, allow", closing the cross-user delete-idempotence gap where any user could successfully DELETE another user's deleted thread. - repositories/sqlite.py + base.py: update_user raises UserNotFoundError on a vanished row instead of silently returning the input. Concurrent delete during password reset can no longer look like a successful update. - runtime/user_context.py: resolve_owner_id() coerces User.id (UUID) to str at the contextvar boundary so SQLAlchemy String(64) columns can bind it. The whole 2.0-rc isolation pipeline was previously broken end-to-end (POST /api/threads → 500 "type 'UUID' is not supported"). - persistence/engine.py: SQLAlchemy listener enables PRAGMA journal_mode=WAL, synchronous=NORMAL, foreign_keys=ON on every new SQLite connection. TC-UPG-06 in the test plan expects WAL; previous code shipped with the default 'delete' journal. - auth_middleware.py: stamp request.state.auth = AuthContext(...) so @require_permission's short-circuit fires; previously every isolation request did a duplicate JWT decode + users SELECT. Also unifies the 401 payload through AuthErrorResponse(...).model_dump(). - app.py: _ensure_admin_user restructure removes the noqa F821 scoping bug where 'password' was referenced outside the branch that defined it. New _announce_credentials helper absorbs the duplicate log block in the fresh-admin and reset-admin branches. * fix(frontend+nginx): rollout CSRF on every state-changing client path The frontend was 100% broken in gateway-pro mode for any user trying to open a specific chat thread. Three cumulative bugs each silently masked the next. LangGraph SDK CSRF gap (api-client.ts) - The Client constructor took only apiUrl, no defaultHeaders, no fetch interceptor. The SDK's internal fetch never sent X-CSRF-Token, so every state-changing /api/langgraph-compat/* call (runs/stream, threads/search, threads/{tid}/history, ...) hit CSRFMiddleware and got 403 before reaching the auth check. UI symptom: empty thread page with no error message; the SPA's hooks swallowed the rejection. - Fix: pass an onRequest hook that injects X-CSRF-Token from the csrf_token cookie per request. Reading the cookie per call (not at construction time) handles login / logout / password-change cookie rotation transparently. The SDK's prepareFetchOptions calls onRequest for both regular requests AND streaming/SSE/reconnect, so the same hook covers runs.stream and runs.joinStream. Raw fetch CSRF gap (7 files) - Audit: 11 frontend fetch sites, only 2 included CSRF (login/setup + account-settings change-password). The other 7 routed through raw fetch() with no header — suggestions, memory, agents, mcp, skills, uploads, and the local thread cleanup hook all 403'd silently. - Fix: enhance fetcher.ts:fetchWithAuth to auto-inject X-CSRF-Token on POST/PUT/DELETE/PATCH from a single shared readCsrfCookie() helper. Convert all 7 raw fetch() callers to fetchWithAuth so the contract is centrally enforced. api-client.ts and fetcher.ts share readCsrfCookie + STATE_CHANGING_METHODS to avoid drift. nginx routing + buffering (nginx.local.conf) - The auth feature shipped without updating the nginx config: per-API explicit location blocks but no /api/v1/auth/, /api/feedback, /api/runs. The frontend's client-side fetches to /api/v1/auth/login/local 404'd from the Next.js side because nginx routed /api/* to the frontend. - Fix: add catch-all `location /api/` that proxies to the gateway. nginx longest-prefix matching keeps the explicit blocks (/api/models, /api/threads regex, /api/langgraph/, ...) winning for their paths. - Fix: disable proxy_buffering + proxy_request_buffering for the frontend `location /` block. Without it, nginx tries to spool large Next.js chunks into /var/lib/nginx/proxy (root-owned) and fails with Permission denied → ERR_INCOMPLETE_CHUNKED_ENCODING → ChunkLoadError. * test(auth): release-validation test infra and new coverage Test fixtures and unit tests added during the validation pass. Router test helpers (NEW: tests/_router_auth_helpers.py) - make_authed_test_app(): builds a FastAPI test app with a stub middleware that stamps request.state.user + request.state.auth and a permissive thread_meta_repo mock. TestClient-based router tests (test_artifacts_router, test_threads_router) use it instead of bare FastAPI() so the new @require_permission(owner_check=True) decorators short-circuit cleanly. - call_unwrapped(): walks the __wrapped__ chain to invoke the underlying handler without going through the authz wrappers. Direct-call tests (test_uploads_router) use it. Typed with ParamSpec so the wrapped signature flows through. Backend test additions - test_auth.py: 7 tests for the new _get_client_ip trust model (no proxy / trusted proxy / untrusted peer / XFF rejection / invalid CIDR / no client). 5 tests for the password blocklist (literal, case-insensitive, strong password accepted, change-password binding, short-password length-check still fires before blocklist). test_update_user_raises_when_row_concurrently_deleted: closes a shipped-without-coverage gap on the new UserNotFoundError contract. - test_thread_meta_repo.py: 4 tests for check_access(require_existing=True) — strict missing-row denial, strict owner match, strict owner mismatch, strict null-owner still allowed (shared rows survive the tightening). - test_ensure_admin.py: 3 tests for _migrate_orphaned_threads / _iter_store_items pagination, covering the TC-UPG-02 upgrade story end-to-end via mock store. Closes the gap where the cursor pagination was untested even though the previous PR rewrote it. - test_threads_router.py: 5 tests for _strip_reserved_metadata (owner_id removal, user_id removal, safe-keys passthrough, empty input, both-stripped). - test_auth_type_system.py: replace "password123" fixtures with Tr0ub4dor3a / AnotherStr0ngPwd! so the new password blocklist doesn't reject the test data. * docs(auth): refresh TC-DOCKER-05 + document Docker validation gap - AUTH_TEST_PLAN.md TC-DOCKER-05: the previous expectation ("admin password visible in docker logs") was stale after the simplify pass that moved credentials to a 0600 file. The grep "Password:" check would have silently failed and given a false sense of coverage. New expectation matches the actual file-based path: 0600 file in DEER_FLOW_HOME, log shows the path (not the secret), reverse-grep asserts no leaked password in container logs. - NEW: docs/AUTH_TEST_DOCKER_GAP.md documents the only un-executed block in the test plan (TC-DOCKER-01..06). Reason: sg_dev validation host has no Docker daemon installed. The doc maps each Docker case to an already-validated bare-metal equivalent (TC-1.1, TC-REENT-01, TC-API-02 etc.) so the gap is auditable, and includes pre-flight reproduction steps for whoever has Docker available. --------- Co-authored-by: greatmengqi <chenmengqi.0376@bytedance.com> |

feat(persistence): add unified persistence layer with event store, token tracking, and feedback (#1930)
* feat(persistence): add SQLAlchemy 2.0 async ORM scaffold
Introduce a unified database configuration (DatabaseConfig) that
controls both the LangGraph checkpointer and the DeerFlow application
persistence layer from a single `database:` config section.
New modules:
- deerflow.config.database_config — Pydantic config with memory/sqlite/postgres backends
- deerflow.persistence — async engine lifecycle, DeclarativeBase with to_dict mixin, Alembic skeleton
- deerflow.runtime.runs.store — RunStore ABC + MemoryRunStore implementation
Gateway integration initializes/tears down the persistence engine in
the existing langgraph_runtime() context manager. Legacy checkpointer
config is preserved for backward compatibility.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(persistence): add RunEventStore ABC + MemoryRunEventStore
Phase 2-A prerequisite for event storage: adds the unified run event
stream interface (RunEventStore) with an in-memory implementation,
RunEventsConfig, gateway integration, and comprehensive tests (27 cases).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(persistence): add ORM models, repositories, DB/JSONL event stores, RunJournal, and API endpoints
Phase 2-B: run persistence + event storage + token tracking.
- ORM models: RunRow (with token fields), ThreadMetaRow, RunEventRow
- RunRepository implements RunStore ABC via SQLAlchemy ORM
- ThreadMetaRepository with owner access control
- DbRunEventStore with trace content truncation and cursor pagination
- JsonlRunEventStore with per-run files and seq recovery from disk
- RunJournal (BaseCallbackHandler) captures LLM/tool/lifecycle events,
accumulates token usage by caller type, buffers and flushes to store
- RunManager now accepts optional RunStore for persistent backing
- Worker creates RunJournal, writes human_message, injects callbacks
- Gateway deps use factory functions (RunRepository when DB available)
- New endpoints: messages, run messages, run events, token-usage
- ThreadCreateRequest gains assistant_id field
- 92 tests pass (33 new), zero regressions
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(persistence): add user feedback + follow-up run association
Phase 2-C: feedback and follow-up tracking.
- FeedbackRow ORM model (rating +1/-1, optional message_id, comment)
- FeedbackRepository with CRUD, list_by_run/thread, aggregate stats
- Feedback API endpoints: create, list, stats, delete
- follow_up_to_run_id in RunCreateRequest (explicit or auto-detected
from latest successful run on the thread)
- Worker writes follow_up_to_run_id into human_message event metadata
- Gateway deps: feedback_repo factory + getter
- 17 new tests (14 FeedbackRepository + 3 follow-up association)
- 109 total tests pass, zero regressions
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test+config: comprehensive Phase 2 test coverage + deprecate checkpointer config
- config.example.yaml: deprecate standalone checkpointer section, activate
unified database:sqlite as default (drives both checkpointer + app data)
- New: test_thread_meta_repo.py (14 tests) — full ThreadMetaRepository coverage
including check_access owner logic, list_by_owner pagination
- Extended test_run_repository.py (+4 tests) — completion preserves fields,
list ordering desc, limit, owner_none returns all
- Extended test_run_journal.py (+8 tests) — on_chain_error, track_tokens=false,
middleware no ai_message, unknown caller tokens, convenience fields,
tool_error, non-summarization custom event
- Extended test_run_event_store.py (+7 tests) — DB batch seq continuity,
make_run_event_store factory (memory/db/jsonl/fallback/unknown)
- Extended test_phase2b_integration.py (+4 tests) — create_or_reject persists,
follow-up metadata, summarization in history, full DB-backed lifecycle
- Fixed DB integration test to use proper fake objects (not MagicMock)
for JSON-serializable metadata
- 157 total Phase 2 tests pass, zero regressions

* config: move default sqlite_dir to .deer-flow/data
Keep SQLite databases alongside other DeerFlow-managed data
(threads, memory) under the .deer-flow/ directory instead of a
top-level ./data folder.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(persistence): remove UTFJSON, use engine-level json_serializer + datetime.now()
- Replace custom UTFJSON type with standard sqlalchemy.JSON in all ORM
models. Add json_serializer=json.dumps(ensure_ascii=False) to all
create_async_engine calls so non-ASCII text (Chinese etc.) is stored
as-is in both SQLite and Postgres.
- Change ORM datetime defaults from datetime.now(UTC) to datetime.now(),
remove UTC imports.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(gateway): simplify deps.py with getter factory + inline repos
- Replace 6 identical getter functions with _require() factory.
- Inline 3 _make_*_repo() factories into langgraph_runtime(), call
get_session_factory() once instead of 3 times.
- Add thread_meta upsert in start_run (services.py).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(docker): add UV_EXTRAS build arg for optional dependencies
Support installing optional dependency groups (e.g. postgres) at
Docker build time via UV_EXTRAS build arg:
UV_EXTRAS=postgres docker compose build
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(journal): fix flush, token tracking, and consolidate tests
RunJournal fixes:
- _flush_sync: retain events in buffer when no event loop instead of
dropping them; worker's finally block flushes via async flush().
- on_llm_end: add tool_calls filter and caller=="lead_agent" guard for
ai_message events; mark message IDs for dedup with record_llm_usage.
- worker.py: persist completion data (tokens, message count) to RunStore
in finally block.
Model factory:
- Auto-inject stream_usage=True for BaseChatOpenAI subclasses with
custom api_base, so usage_metadata is populated in streaming responses.
Test consolidation:
- Delete test_phase2b_integration.py (redundant with existing tests).
- Move DB-backed lifecycle test into test_run_journal.py.
- Add tests for stream_usage injection in test_model_factory.py.
- Clean up executor/task_tool dead journal references.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(events): widen content type to str|dict in all store backends
Allow event content to be a dict (for structured OpenAI-format messages)
in addition to plain strings. Dict values are JSON-serialized for the DB
backend and deserialized on read; memory and JSONL backends handle dicts
natively. Trace truncation now serializes dicts to JSON before measuring.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(events): use metadata flag instead of heuristic for dict content detection
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(converters): add LangChain-to-OpenAI message format converters
Pure functions langchain_to_openai_message, langchain_to_openai_completion,
langchain_messages_to_openai, and _infer_finish_reason for converting
LangChain BaseMessage objects to OpenAI Chat Completions format, used by
RunJournal for event storage. 15 unit tests added.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(converters): handle empty list content as null, clean up test
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(events): human_message content uses OpenAI user message format
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat(events): ai_message uses OpenAI format, add ai_tool_call message event
- ai_message content now uses {"role": "assistant", "content": "..."} format
- New ai_tool_call message event emitted when lead_agent LLM responds with tool_calls
- ai_tool_call uses langchain_to_openai_message converter for consistent format
- Both events include finish_reason in metadata ("stop" or "tool_calls")
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(events): add tool_result message event with OpenAI tool message format
Cache tool_call_id from on_tool_start keyed by run_id as fallback for on_tool_end,
then emit a tool_result message event (role=tool, tool_call_id, content) after each
successful tool completion.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat(events): summary content uses OpenAI system message format
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(events): replace llm_start/llm_end with llm_request/llm_response in OpenAI format
Add on_chat_model_start to capture structured prompt messages as llm_request events.
Replace llm_end trace events with llm_response using OpenAI Chat Completions format.
Track llm_call_index to pair request/response events.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(events): add record_middleware method for middleware trace events
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test(events): add full run sequence integration test for OpenAI content format
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat(events): align message events with checkpoint format and add middleware tag injection
- Message events (ai_message, ai_tool_call, tool_result, human_message) now use
BaseMessage.model_dump() format, matching LangGraph checkpoint values.messages
- on_tool_end extracts tool_call_id/name/status from ToolMessage objects
- on_tool_error now emits tool_result message events with error status
- record_middleware uses middleware:{tag} event_type and middleware category
- Summarization custom events use middleware:summarize category
- TitleMiddleware injects middleware:title tag via get_config() inheritance
- SummarizationMiddleware model bound with middleware:summarize tag
- Worker writes human_message using HumanMessage.model_dump()
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(threads): switch search endpoint to threads_meta table and sync title
- POST /api/threads/search now queries threads_meta table directly,
removing the two-phase Store + Checkpointer scan approach
- Add ThreadMetaRepository.search() with metadata/status filters
- Add ThreadMetaRepository.update_display_name() for title sync
- Worker syncs checkpoint title to threads_meta.display_name on run completion
- Map display_name to values.title in search response for API compatibility
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(threads): history endpoint reads messages from event store
- POST /api/threads/{thread_id}/history now combines two data sources:
checkpointer for checkpoint_id, metadata, title, thread_data;
event store for messages (complete history, not truncated by summarization)
- Strip internal LangGraph metadata keys from response
- Remove full channel_values serialization in favor of selective fields
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: remove duplicate optional-dependencies header in pyproject.toml
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(middleware): pass tagged config to TitleMiddleware ainvoke call
Without the config, the middleware:title tag was not injected,
causing the LLM response to be recorded as a lead_agent ai_message
in run_events.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: resolve merge conflict in .env.example
Keep both DATABASE_URL (from persistence-scaffold) and WECOM
credentials (from main) after the merge.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(persistence): address review feedback on PR #1851
- Fix naive datetime.now() → datetime.now(UTC) in all ORM models
- Fix seq race condition in DbRunEventStore.put() with FOR UPDATE
and UNIQUE(thread_id, seq) constraint
- Encapsulate _store access in RunManager.update_run_completion()
- Deduplicate _store.put() logic in RunManager via _persist_to_store()
- Add update_run_completion to RunStore ABC + MemoryRunStore
- Wire follow_up_to_run_id through the full create path
- Add error recovery to RunJournal._flush_sync() lost-event scenario
- Add migration note for search_threads breaking change
- Fix test_checkpointer_none_fix mock to set database=None

* chore: update uv.lock
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(persistence): address 22 review comments from CodeQL, Copilot, and Code Quality
Bug fixes:
- Sanitize log params to prevent log injection (CodeQL)
- Reset threads_meta.status to idle/error when run completes
- Attach messages only to latest checkpoint in /history response
- Write threads_meta on POST /threads so new threads appear in search
Lint fixes:
- Remove unused imports (journal.py, migrations/env.py, test_converters.py)
- Convert lambda to named function (engine.py, Ruff E731)
- Remove unused logger definitions in repos (Ruff F841)
- Add logging to JSONL decode errors and empty except blocks
- Separate assert side-effects in tests (CodeQL)
- Remove unused local variables in tests (Ruff F841)
- Fix max_trace_content truncation to use byte length, not char length

* Potential fix for pull request finding 'Statement has no effect'
Co-authored-by: Copilot Autofix powered by AI <223894421+github-code-quality[bot]@users.noreply.github.com>
* refactor(runtime): introduce RunContext to reduce run_agent parameter bloat
Extract checkpointer, store, event_store, run_events_config, thread_meta_repo,
and follow_up_to_run_id into a frozen RunContext dataclass. Add get_run_context()
in deps.py to build the base context from app.state singletons. start_run() uses
dataclasses.replace() to enrich per-run fields before passing ctx to run_agent.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(gateway): move sanitize_log_param to app/gateway/utils.py
Extract the log-injection sanitizer from routers/threads.py into a shared
utils module and rename to sanitize_log_param (public API). Eliminates the
reverse service → router import in services.py.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* perf: use SQL aggregation for feedback stats and thread token usage
Replace Python-side counting in FeedbackRepository.aggregate_by_run with
a single SELECT COUNT/SUM query. Add RunStore.aggregate_tokens_by_thread
abstract method with SQL GROUP BY implementation in RunRepository and
Python fallback in MemoryRunStore. Simplify the thread_token_usage
endpoint to delegate to the new method, eliminating the limit=10000
truncation risk.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: annotate DbRunEventStore.put() as low-frequency path
Add docstring clarifying that put() opens a per-call transaction with
FOR UPDATE and should only be used for infrequent writes (currently
just the initial human_message event). High-throughput callers should
use put_batch() instead.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(threads): fall back to Store search when ThreadMetaRepository is unavailable
When database.backend=memory (default) or no SQL session factory is
configured, search_threads now queries the LangGraph Store instead of
returning 503. Returns empty list if neither Store nor repo is available.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(persistence): introduce ThreadMetaStore ABC for backend-agnostic thread metadata
Add ThreadMetaStore abstract base class with create/get/search/update/delete
interface. ThreadMetaRepository (SQL) now inherits from it. New
MemoryThreadMetaStore wraps LangGraph BaseStore for memory-mode deployments.
deps.py now always provides a non-None thread_meta_repo, eliminating all
`if thread_meta_repo is not None` guards in services.py, worker.py, and
routers/threads.py. search_threads no longer needs a Store fallback branch.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(history): read messages from checkpointer instead of RunEventStore
The /history endpoint now reads messages directly from the
checkpointer's channel_values (the authoritative source) instead of
querying RunEventStore.list_messages(). The RunEventStore API is
preserved for other consumers.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(persistence): address new Copilot review comments
- feedback.py: validate thread_id/run_id before deleting feedback
- jsonl.py: add path traversal protection with ID validation

* fix(config): resolve sqlite_dir relative to CWD, not Paths.base_dir
resolve_path() resolves relative to Paths.base_dir (.deer-flow),
which double-nested the path to .deer-flow/.deer-flow/data/app.db.
Use Path.resolve() (CWD-relative) instead.

* Feature/feishu receive file (#1608)
* feat(feishu): add channel file materialization hook for inbound messages
- Introduce Channel.receive_file(msg, thread_id) as a base method for file materialization; default is no-op.
- Implement FeishuChannel.receive_file to download files/images from Feishu messages, save to sandbox, and inject virtual paths into msg.text.
- Update ChannelManager to call receive_file for any channel if msg.files is present, enabling downstream model access to user-uploaded files.
- No impact on Slack/Telegram or other channels (they inherit the default no-op).
* style(backend): format code with ruff for lint compliance
- Auto-formatted packages/harness/deerflow/agents/factory.py and tests/test_create_deerflow_agent.py using `ruff format`
- Ensured both files conform to project linting standards
- Fixes CI lint check failures caused by code style issues
* fix(feishu): handle file write operation asynchronously to prevent blocking
* fix(feishu): rename GetMessageResourceRequest to _GetMessageResourceRequest and remove redundant code
* test(feishu): add tests for receive_file method and placeholder replacement
* fix(manager): remove unnecessary type casting for channel retrieval
* fix(feishu): update logging messages to reflect resource handling instead of image
* fix(feishu): sanitize filename by replacing invalid characters in file uploads
* fix(feishu): improve filename sanitization and reorder image key handling in message processing
* fix(feishu): add thread lock to prevent filename conflicts during file downloads

fix: cap prompt caching breakpoints at 4 to prevent API 400 errors (#2449)
* fix: cap prompt caching breakpoints at 4 to prevent API 400 errors (fixes #2448) The previous _apply_prompt_caching() attached cache_control to every text block in the system prompt, every content block in the last N messages, and the last tool definition. In multi-turn conversations with structured content blocks this easily exceeded the 4-breakpoint hard limit enforced by both the Anthropic API and AWS Bedrock, producing a 400 Bad Request (or a silent "No generations found in stream" when streaming). Fix: collect all candidate blocks in document order, then apply cache_control only to the last MAX_CACHE_BREAKPOINTS (4) of them. Later breakpoints cover a larger prefix and therefore yield better cache hit rates, making this the optimal placement strategy as well as the safe one. Adds 13 unit tests covering the budget cap, edge cases, and correct last-candidate placement. * docs: clarify _apply_prompt_caching docstring includes tool definitions Per Copilot review: the implementation also caches the last tool definition (see the candidates list at lines 202-205), so the docstring summary should explicitly mention tools alongside system and recent messages. * Fix the lint error * style: fix ruff format check for test_claude_provider_prompt_caching.py Add the missing blank line before the 'Edge cases' section comment so that ruff format --check passes in CI. --------- Co-authored-by: octo-patch <octo-patch@github.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat(mcp): support custom tool interceptors via extensions_config.json (#2451)
* feat(mcp): support custom tool interceptors via extensions_config.json
Add a generic extension point for registering custom MCP tool
interceptors through `extensions_config.json`. This allows downstream
projects to inject per-request header manipulation, auth context
propagation, or other cross-cutting concerns without modifying
DeerFlow source code.
Interceptors are declared as Python callable paths in a new
`mcpInterceptors` array field and loaded via the existing
`resolve_variable` reflection mechanism:
```json
{
"mcpInterceptors": [
"my_package.mcp.auth:build_auth_interceptor"
]
}
```
Each entry must resolve to a no-arg builder function that returns an
async interceptor compatible with `MultiServerMCPClient`'s
`tool_interceptors` interface.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test(mcp): add unit tests for custom tool interceptors
Cover all branches of the mcpInterceptors loading logic:
- valid interceptor loaded and appended to tool_interceptors
- multiple interceptors loaded in declaration order
- builder returning None is skipped
- resolve_variable ImportError logged and skipped
- builder raising exception logged and skipped
- absent mcpInterceptors field is safe (no-op)
- custom interceptors coexist with OAuth interceptor

* fix(mcp): validate mcpInterceptors type and fix lint warnings
Address review feedback:
1. Validate mcpInterceptors config value before iterating:
- Accept a single string and normalize to [string]
- Ignore None silently
- Log warning and skip for non-list/non-string types
2. Fix ruff F841 lint errors in tests:
- Rename _make_mock_env to _make_patches, embed mock_client
- Remove unused `as mock_cls` bindings where not needed
- Extract _get_interceptors() helper to reduce repetition
3. Add two new test cases for type validation:
- test_mcp_interceptors_single_string_is_normalized
- test_mcp_interceptors_invalid_type_logs_warning

* fix(mcp): validate interceptor return type and fix import mock path
Address review feedback:
1. Validate builder return type with callable() check:
- callable interceptor → append to tool_interceptors
- None → silently skip (builder opted out)
- non-callable → log warning with type name and skip
2. Fix test mock path: resolve_variable is a top-level import in
tools.py, so mock deerflow.mcp.tools.resolve_variable instead of
deerflow.reflection.resolve_variable to correctly intercept calls.
3. Add test_custom_interceptor_non_callable_return_logs_warning to
cover the new non-callable validation branch.

* docs(mcp): add mcpInterceptors example and documentation
- Add mcpInterceptors field to extensions_config.example.json
- Add "Custom Tool Interceptors" section to MCP_SERVER.md with
configuration format, example interceptor code, and edge case
behavior notes

fix(jina): log transient failures at WARNING without traceback (#2484) (#2485)
The exception handler in JinaClient.crawl used logger.exception, which emits an ERROR-level record with the full httpx/httpcore/anyio traceback for every transient network failure (timeout, connection refused). Other search/crawl providers in the project log the same class of recoverable failures as a single line. One offline/slow-network session could produce dozens of multi-frame ERROR stack traces, drowning out real problems. Switch to logger.warning with a concise message that includes the exception type and its str, matching the style used elsewhere for recoverable transient failures (aio_sandbox, ddg, etc.). The exception type now also surfaces into the returned "Error: ..." string so callers retain diagnostic signal. Adds a regression test that asserts the log record is WARNING, carries no exc_info, and includes the exception class name.

fix(gateway): bound lifespan shutdown hooks to prevent worker hang under uvicorn reload (#2331)
* fix(gateway): bound lifespan shutdown hooks to prevent worker hang Gateway worker can hang indefinitely in `uvicorn --reload` mode with the listening socket still bound — all /api/* requests return 504, and SIGKILL is the only recovery. Root cause (py-spy dump from a reproduction showed 16+ stacked frames of signal_handler -> Event.set -> threading.Lock.__enter__ on the main thread): CPython's `threading.Event` uses `Condition(Lock())` where the inner Lock is non-reentrant. uvicorn's BaseReload signal handler calls `should_exit.set()` directly from signal context; if a second signal (SIGTERM/SIGHUP from the reload supervisor, or watchfiles-triggered reload) arrives while the first handler holds the Lock, the reentrant call deadlocks on itself. The reload supervisor keeps sending those signals only when the worker fails to exit promptly. DeerFlow's lifespan currently awaits `stop_channel_service()` with no timeout; if a channel's `stop()` stalls (e.g. Feishu/Slack WebSocket waiting for an ack), the worker can't exit, the supervisor keeps signaling, and the deadlock becomes reachable. This is a defense-in-depth fix — it does not repair the upstream uvicorn/CPython issue, but it ensures DeerFlow's lifespan exits within a bounded window so the supervisor has no reason to keep firing signals. No behavior change on the happy path. Wraps the shutdown hook in `asyncio.wait_for(timeout=5.0)` and logs a warning on timeout before proceeding to worker exit.

fix(skills): validate bundled SKILL.md front-matter in CI (fixes #2443) (#2457)
* fix(skills): validate bundled SKILL.md front-matter in CI (fixes #2443) Adds a parametrized backend test that runs `_validate_skill_frontmatter` against every bundled SKILL.md under `skills/public/`, so a broken front-matter fails CI with a per-skill error message instead of surfacing as a runtime gateway-load warning. The new test caught two pre-existing breakages on `main` and fixes them: * `bootstrap/SKILL.md`: the unquoted description had a second `:` mid-line ("Also trigger for updates: ..."), which YAML parses as a nested mapping ("mapping values are not allowed here"). Rewrites the description as a folded scalar (`>-`), which preserves the original wording (including the embedded colon, double quotes, and apostrophes) without further escaping. This complements PR #2436 (single-file colon→hyphen patch) with a more general convention that survives future edits. * `chart-visualization/SKILL.md`: used `dependency:` which is not in `ALLOWED_FRONTMATTER_PROPERTIES`. Renamed to `compatibility:`, the documented field for "Required tools, dependencies" per skill-creator. No code reads `dependency` (verified by grep across backend/). * Apply suggestions from code review Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * Fix the lint error --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> |

fix(subagent): inherit parent agent's tool_groups in task_tool (#2305)
* fix(subagent): inherit parent agent's tool_groups in task_tool
When a custom agent defines tool_groups (e.g. [file:read, file:write, bash]),
the restriction is correctly applied to the lead agent. However, when the lead
agent delegates work to a subagent via the task tool, get_available_tools() is
called without the groups parameter, causing the subagent to receive ALL tools
(including web_search, web_fetch, image_search, etc.) regardless of the parent
agent's configuration.
This fix propagates tool_groups through run metadata so that task_tool passes
the same group filter when building the subagent's tool set.
Changes:
- agent.py: include tool_groups in run metadata
- task_tool.py: read tool_groups from metadata and pass to get_available_tools()
* fix: initialize metadata before conditional block and update tests for tool_groups propagation
- Initialize metadata = {} before the 'if runtime is not None' block to
avoid Ruff F821 (possibly-undefined variable) and simplify the
parent_tool_groups expression.
- Update existing test assertion to expect groups=None in
get_available_tools call signature.
- Add 3 new test cases:
- test_task_tool_propagates_tool_groups_to_subagent
- test_task_tool_no_tool_groups_passes_none
- test_task_tool_runtime_none_passes_groups_none

fix(sandbox): add missing path masking in ls_tool output (#2317)
ls_tool was the only file-system tool that did not call mask_local_paths_in_output() before returning its result, causing host absolute paths (e.g. /Users/.../backend/.deer-flow/knowledge-base/...) to leak to the LLM instead of the expected virtual paths (/mnt/knowledge-base/...). This patch: - Adds the mask_local_paths_in_output() call to ls_tool, consistent with bash_tool, glob_tool and grep_tool. - Initialises thread_data = None before the is_local_sandbox branch (same pattern as glob_tool) so the variable is always in scope. - Adds three new tests covering user-data path masking, skills path masking and the empty-directory edge case. |

fix: Memory update system has cache corruption, data loss, and thread-safety bugs (#2251)
* fix(memory): cache corruption, thread-safety, and caller mutation bugs
Bug 1 (updater.py): deep-copy current_memory before passing to
_apply_updates() so a subsequent save() failure cannot leave a
partially-mutated object in the storage cache.
Bug 3 (storage.py): add _cache_lock (threading.Lock) to
FileMemoryStorage and acquire it around every read/write of
_memory_cache, fixing concurrent-access races between the background
timer thread and HTTP reload calls.
Bug 4 (storage.py): replace in-place mutation
memory_data["lastUpdated"] = ...
with a shallow copy
memory_data = {**memory_data, "lastUpdated": ...}
so save() no longer silently modifies the caller's dict.
Regression tests added for all three bugs in test_memory_storage.py
and test_memory_updater.py.

fix(checkpointer): create parent directory before opening SQLite in sync provider (#2272)
* fix(checkpointer): create parent directory before opening SQLite in sync provider
The sync checkpointer factory (_sync_checkpointer_cm) opens a SQLite
connection without first ensuring the parent directory exists. The async
provider and both store providers already call ensure_sqlite_parent_dir(),
but this call was missing from the sync path.
When the deer-flow harness package is used from an external virtualenv
(where the .deer-flow directory is not pre-created), the missing parent
directory causes:
sqlite3.OperationalError: unable to open database file
Add the missing ensure_sqlite_parent_dir() call in the sync SQLite
branch, consistent with the async provider, and add a regression test.
Closes #2259
* style: fix ruff format + add call-order assertion for ensure_parent_dir
- Fix formatting in test_checkpointer.py (ruff format)
- Add test_sqlite_ensure_parent_dir_before_connect to verify
ensure_sqlite_parent_dir is called before from_conn_string
(addresses Copilot review suggestion)

fix(todo-middleware): prevent premature agent exit with incomplete todos (#2135)
* fix(todo-middleware): prevent premature agent exit with incomplete todos When plan mode is active (is_plan_mode=True), the agent occasionally exits the loop and outputs a final response while todo items are still incomplete. This happens because the routing edge only checks for tool_calls, not todo completion state. Fixes #2112 Add an after_model override to TodoMiddleware with @hook_config(can_jump_to=["model"]). When the model produces a response with no tool calls but there are still incomplete todos, the middleware injects a todo_completion_reminder HumanMessage and returns jump_to=model to force another model turn. A cap of 2 reminders prevents infinite loops when the agent cannot make further progress. Also adds _completion_reminder_count() helper and 14 new unit tests covering all edge cases of the new after_model / aafter_model logic. * Remove unnecessary blank line in test file * Fix runtime argument annotation in before_model * Apply suggestions from code review Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: octo-patch <octo-patch@github.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> |

fix(title): strip <think> tags from title model responses and assistant context (#1927)
* fix(title): strip <think> tags from title model responses and assistant context Reasoning models (e.g. minimax M2.7, DeepSeek-R1) emit <think>...</think> blocks before their actual output. When such a model is used as the title model (or as the main agent), the raw thinking content leaked into the thread title stored in state, so the chat list showed the internal monologue instead of a meaningful title. Fixes #1884 - Add `_strip_think_tags()` helper using a regex to remove all <think>...</think> blocks - Apply it in `_parse_title()` so the title model response is always clean - Apply it to the assistant message in `_build_title_prompt()` so thinking content from the first AI turn is not fed back to the title model - Add four new unit tests covering: stripping in parse, think-only response, assistant prompt stripping, and end-to-end async flow with think tags * Fix the lint error --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix: wrap blocking readability call with asyncio.to_thread in web_fetch (#2157)
* fix: wrap blocking readability call with asyncio.to_thread in web_fetch The readability extractor internally spawns a Node.js subprocess via readabilipy, which blocks the async event loop and causes a BlockingError when web_fetch is invoked inside LangGraph's async runtime. Wrap the synchronous extract_article call with asyncio.to_thread to offload it to a thread pool, unblocking the event loop. Note: community/infoquest/tools.py has the same latent issue and should be addressed in a follow-up PR. Closes #2152 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * test: verify web_fetch offloads extraction via asyncio.to_thread Add a regression test that monkeypatches asyncio.to_thread to confirm readability extraction is offloaded to a worker thread, preventing future refactors from reintroducing the blocking call.

feat(subagents): allow model override per subagent in config.yaml (#2064)
* feat(subagents): allow model override per subagent in config.yaml Wire the existing SubagentConfig.model field to config.yaml so users can assign different models to different subagent types. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test(subagents): cover model override in SubagentsAppConfig + registry Addresses review feedback on #2064: - registry.py: update stale inline comment — the block now applies timeout, max_turns AND model overrides, not just timeout. - test_subagent_timeout_config.py: add coverage for model override resolution across SubagentOverrideConfig, SubagentsAppConfig (get_model_for + load), and registry.get_subagent_config: - per-agent model override is applied to registry-returned config - omitted `model` keeps the builtin value - explicit `model: null` in config.yaml is equivalent to omission - model override on one agent does not affect other agents - model override preserves all other fields (name, description, timeout_seconds, max_turns) - model override does not mutate BUILTIN_SUBAGENTS Copilot's suggestion (3) "setting model to 'inherit' forces inheritance" is skipped intentionally: there is no 'inherit' sentinel in the current implementation — model is `str | None`, and None already means "inherit from parent". Adding a sentinel would be a new feature, not test coverage for this PR. Tests run locally: 51 passed (37 existing + 14 new / expanded). * test(subagents): reject empty-string model at config load time Addresses WillemJiang's review comment on #2064 (empty-string edge case): - subagents_config.py: add `min_length=1` to the `model` field on SubagentOverrideConfig. `model: ""` in config.yaml would otherwise bypass the `is not None` check and reach create_chat_model(name="") as a confusing runtime error. This is symmetric with the existing `ge=1` guards on timeout_seconds / max_turns, so the validation style stays consistent across all three override fields. - test_subagent_timeout_config.py: add test_rejects_empty_model mirroring the existing test_rejects_zero / test_rejects_negative cases; update the docstring on test_model_accepts_any_string (now test_model_accepts_any_non_empty_string) to reflect the new guard. Not addressing the first comment (validating `model` against the `models:` section at load time) in this PR. `SubagentsAppConfig` is scoped to the `subagents:` block and cannot see the sibling `models:` section, so proper cross-section validation needs a second pass or a structural change that is out of scope here — and the current behavior is consistent with how timeout_seconds / max_turns work today. Happy to track this as a follow-up issue covering cross-section validation uniformly for all three fields. Tests run locally: 52 passed in this file; 1847 passed, 18 skipped across the full backend suite. Ruff check + format clean.

feat(channels): add Discord channel integration (#1806)
* feat(channels): add Discord channel integration Add a Discord bot channel following the existing Telegram/Slack pattern. The bot listens for messages, creates conversation threads, and relays responses back to Discord with 2000-char message splitting. - DiscordChannel extends Channel base class - Lazy imports discord.py with install hint - Thread-based conversations (each Discord thread maps to a DeerFlow thread) - Allowed guilds filter for access control - File attachment support via discord.File - Registered in service.py and manager.py Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(channels): address Copilot review suggestions for Discord integration - Disable @everyone/@here mentions via AllowedMentions.none() - Add 10s timeout to client close to prevent shutdown hangs - Log publish_inbound errors via future callback instead of silently dropping - Open file handle on caller thread to avoid cross-thread ownership issues - Notify user in channel when thread creation fails Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(discord): resolve lint errors in Discord channel - Replace asyncio.TimeoutError with builtin TimeoutError (UP041) - Remove extraneous f-string prefix (F541) - Apply ruff format Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(tests): remove fake langgraph_sdk shim from test_discord_channel The module-level sys.modules.setdefault shim installed a fake langgraph_sdk.errors.ConflictError during pytest collection. Because pytest imports all test modules before running them, test_channels.py then imported the fake ConflictError instead of the real one. In test_handle_feishu_stream_conflict_sends_busy_message, the test constructs ConflictError(message, response=..., body=...). The fake only subclasses Exception (which takes no kwargs), so the construction raised TypeError. The manager's _is_thread_busy_error check then saw a TypeError instead of a ConflictError and fell through to the generic 'An error occurred' message. langgraph_sdk is a real dependency, so the shim is unnecessary. Removing it makes both test files import the same real ConflictError and the full suite pass (1773 passed, 15 skipped). --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(sandbox): resolve paths in read_file/write_file content for LocalSandbox (#1935)
* fix(sandbox): resolve paths in read_file/write_file content for LocalSandbox In LocalSandbox mode, read_file and write_file now transform container paths in file content, matching the path handling behavior of bash tool. - write_file: resolves virtual paths in content to system paths before writing, so scripts with /mnt/user-data paths work when executed - read_file: reverse-resolves system paths back to virtual paths in returned content for consistency This fixes scenarios where agents write Python scripts with virtual paths, then execute them via bash tool expecting the paths to work. Fixes #1778 * fix(sandbox): address Copilot review — dedicated content resolver + forward-slash safety + tests - Extract _resolve_paths_in_content() separate from _resolve_paths_in_command() to decouple file-content path resolution from shell-command parsing - Normalize resolved paths to forward slashes to avoid Windows backslash escape issues in source files (e.g. \U in Python string literals) - Add 4 focused tests: write resolves content, forward-slash guarantee, read reverse-resolves content, and write→read roundtrip * style: fix ruff lint — remove extraneous f-string prefix * fix(sandbox): only reverse-resolve paths in agent-written files read_file previously applied _reverse_resolve_paths_in_output to ALL file content, which could silently rewrite paths in user uploads and external tool output (Willem Jiang review on #1935). Now tracks files written through write_file in _agent_written_paths. Only those files get reverse-resolved on read. Non-agent files are returned as-is. --------- Co-authored-by: JasonOA888 <JasonOA888@users.noreply.github.com> |

fix(middleware): add per-tool-type frequency detection to LoopDetectionMiddleware (#1988)
* fix(middleware): add per-tool-type frequency detection to LoopDetectionMiddleware The existing hash-based loop detection only catches identical tool call sets. When the agent calls the same tool type (e.g. read_file) on many different files, each call produces a unique hash and bypasses detection. This causes the agent to exhaust recursion_limit, consuming 150K-225K tokens per failed run. Add a second detection layer that tracks cumulative call counts per tool type per thread. Warns at 30 calls (configurable) and forces stop at 50. The hard stop message now uses the actual returned message instead of a hardcoded constant, so both hash-based and frequency-based stops produce accurate diagnostics. Also fix _apply() to use the warning message returned by _track_and_check() for hard stops, instead of always using _HARD_STOP_MSG. Closes #1987 * Apply suggestions from code review Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * fix(lint): remove unused imports and fix line length - Remove unused _TOOL_FREQ_HARD_STOP_MSG and _TOOL_FREQ_WARNING_MSG imports from test file (F401) - Break long _TOOL_FREQ_WARNING_MSG string to fit within 240 char limit (E501) * style: apply ruff format * test: add LRU eviction and per-thread reset coverage for frequency state Address review feedback from @WillemJiang: - Verify _tool_freq and _tool_freq_warned are cleaned on LRU eviction - Add test for reset(thread_id=...) clearing only the target thread's frequency state while leaving others intact * fix(makefile): route Windows shell-script targets through Git Bash (#2060) --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-authored-by: Asish Kumar <87874775+officialasishkumar@users.noreply.github.com> |

feat(provisioner): add optional PVC support for sandbox volumes (#2020)

fix(backend): stream DeerFlowClient AI text as token deltas (#1969) (#1974)
* fix(backend): stream DeerFlowClient AI text as token deltas (#1969) DeerFlowClient.stream() subscribed to LangGraph stream_mode=["values", "custom"] which only delivers full-state snapshots at graph-node boundaries, so AI replies were dumped as a single messages-tuple event per node instead of streaming token-by-token. `client.stream("hello")` looked identical to `client.chat("hello")` — the bug reported in #1969. Subscribe to "messages" mode as well, forward AIMessageChunk deltas as messages-tuple events with delta semantics (consumers accumulate by id), and dedup the values-snapshot path so it does not re-synthesize AI text that was already streamed. Introduce a per-id usage_metadata counter so the final AIMessage in the values snapshot and the final "messages" chunk — which carry the same cumulative usage — are not double-counted. chat() now accumulates per-id deltas and returns the last message's full accumulated text. Non-streaming mock sources (single event per id) are a degenerate case of the same logic, keeping existing callers and tests backward compatible. Verified end-to-end against a real LLM: a 15-number count emits 35 messages-tuple events with BPE subword boundaries clearly visible ("eleven" -> "ele" / "ven", "twelve" -> "tw" / "elve"), 476ms across the window, end-event usage matches the values-snapshot usage exactly (not doubled). tests/test_client_live.py::TestLiveStreaming passes. New unit tests: - test_messages_mode_emits_token_deltas: 3 AIMessageChunks produce 3 delta events with correct content/id/usage, values-snapshot does not duplicate, usage counted once. - test_chat_accumulates_streamed_deltas: chat() rebuilds full text from deltas. - test_messages_mode_tool_message: ToolMessage delivered via messages mode is not duplicated by the values-snapshot synthesis path. The stream() docstring now documents why this client does not reuse Gateway's run_agent() / StreamBridge pipeline (sync vs async, raw LangChain objects vs serialized dicts, single caller vs HTTP fan-out). Fixes #1969 * refactor(backend): simplify DeerFlowClient streaming helpers (#1969) Post-review cleanup for the token-level streaming fix. No behavior change for correct inputs; one efficiency regression fixed. Fix: chat() O(n²) accumulator ----------------------------- `chat()` accumulated per-id text via `buffers[id] = buffers.get(id,"") + delta`, which is O(n) per concat → O(n²) total over a streamed response. At ~2 KB cumulative text this becomes user-visible; at 50 KB / 5000 chunks it costs roughly 100-300 ms of pure copying. Switched to `dict[str, list[str]]` + `"".join()` once at return. Cleanup ------- - Extract `_serialize_tool_calls`, `_ai_text_event`, `_ai_tool_calls_event`, and `_tool_message_event` static helpers. The messages-mode and values-mode branches previously repeated four inline dict literals each; they now call the same builders. - `StreamEvent.type` is now typed as `Literal["values", "messages-tuple", "custom", "end"]` via a `StreamEventType` alias. Makes the closed set explicit and catches typos at type-check time. - Direct attribute access on `AIMessage`/`AIMessageChunk`: `.usage_metadata`, `.tool_calls`, `.id` all have default values on the base class, so the `getattr(..., None)` fallbacks were dead code. Removed from the hot path. - `_account_usage` parameter type loosened to `Any` so that LangChain's `UsageMetadata` TypedDict is accepted under strict type checking. - Trimmed narrating comments on `seen_ids` / `streamed_ids` / the values-synthesis skip block; kept the non-obvious ones that document the cross-mode dedup invariant. Net diff: -15 lines. All 132 unit tests + harness boundary test still pass; ruff check and ruff format pass. * docs(backend): add STREAMING.md design note (#1969) Dedicated design document for the token-level streaming architecture, prompted by the bug investigation in #1969. Contents: - Why two parallel streaming paths exist (Gateway HTTP/async vs DeerFlowClient sync/in-process) and why they cannot be merged. - LangGraph's three-layer mode naming (Graph "messages" vs Platform SDK "messages-tuple" vs HTTP SSE) and why a shared string constant would be harmful. - Gateway path: run_agent + StreamBridge + sse_consumer with a sequence diagram. - DeerFlowClient path: sync generator + direct yield, delta semantics, chat() accumulator. - Why the three id sets (seen_ids / streamed_ids / counted_usage_ids) each carry an independent invariant and cannot be collapsed. - End-to-end sequence for a real conversation turn. - Lessons from #1969: why mock-based tests missed the bug, why BPE subword boundaries in live output are the strongest correctness signal, and the regression test that locks it in. - Source code location index. Also: - Link from backend/CLAUDE.md Embedded Client section. - Link from backend/docs/README.md under Feature Documentation. * test(backend): add refactor regression guards for stream() (#1969) Three new tests in TestStream that lock the contract introduced by PR #1974 so any future refactor (sync->async migration, sharing a core with Gateway's run_agent, dedup strategy change) cannot silently change behavior. - test_dedup_requires_messages_before_values_invariant: canary that documents the order-dependence of cross-mode dedup. streamed_ids is populated only by the messages branch, so values-before-messages for the same id produces duplicate AI text events. Real LangGraph never inverts this order, but a refactor that does (or that makes dedup idempotent) must update this test deliberately. - test_messages_mode_golden_event_sequence: locks the *exact* event sequence (4 events: 2 messages-tuple deltas, 1 values snapshot, 1 end) for a canonical streaming turn. List equality gives a clear diff on any drift in order, type, or payload shape. - test_chat_accumulates_in_linear_time: perf canary for the O(n^2) fix in commit 1f11ba10. 10,000 single-char chunks must accumulate in under 1s; the threshold is wide enough to pass on slow CI but tight enough to fail if buffer = buffer + delta is restored. All three tests pass alongside the existing 12 TestStream tests (15/15). ruff check + ruff format clean. * docs(backend): clarify stream() docstring on JSON serialization (#1969) Replace the misleading "raw LangChain objects (AIMessage, usage_metadata as dataclasses), not dicts" claim in the "Why not reuse Gateway's run_agent?" section. The implementation already yields plain Python dicts (StreamEvent.data is dict, and usage_metadata is a TypedDict), so the original wording suggested a richer return type than the API actually delivers. The corrected wording focuses on what is actually true and relevant: this client skips the JSON/SSE serialization layer that Gateway adds for HTTP wire transmission, and yields stream event payloads directly as Python data structures. Addresses Copilot review feedback on PR #1974. * test(backend): document none-id messages dedup limitation (#1969) Add test_none_id_chunks_produce_duplicates_known_limitation to TestStream that explicitly documents and asserts the current behavior when an LLM provider emits AIMessageChunk with id=None (vLLM, certain custom backends). The cross-mode dedup machinery cannot record a None id in streamed_ids (guarded by ``if msg_id:``), so the values snapshot's reassembled AIMessage with a real id falls through and synthesizes a duplicate AI text event. The test asserts len == 2 and locks this as a known limitation rather than silently letting future contributors hit it without context. Why this is documented rather than fixed: * Falling back to ``metadata.get("id")`` does not help — LangGraph's messages-mode metadata never carries the message id. * Synthesizing ``f"_synth_{id(msg_chunk)}"`` only helps if the values snapshot uses the same fallback, which it does not. * A real fix requires provider cooperation (always emit chunk ids) or content-based dedup (false-positive risk), neither of which belongs in this PR. If a real fix lands, replace this test with a positive assertion that dedup works for None-id chunks. Addresses Copilot review feedback on PR #1974 (client.py:515). * fix(frontend): UI polish - fix CSS typo, dark mode border, and hardcoded colors (#1942) - Fix `font-norma` typo to `font-normal` in message-list subtask count - Fix dark mode `--border` using reddish hue (22.216) instead of neutral - Replace hardcoded `rgb(184,184,192)` in hero with `text-muted-foreground` - Replace hardcoded `bg-[#a3a1a1]` in streaming indicator with `bg-muted-foreground` - Add missing `font-sans` to welcome description `<pre>` for consistency - Make case-study-section padding responsive (`px-4 md:px-20`) Closes #1940 * docs: clarify deployment sizing guidance (#1963) * fix(frontend): prevent stale 'new' thread ID from triggering 422 history requests (#1960) After history.replaceState updates the URL from /chats/new to /chats/{UUID}, Next.js useParams does not update because replaceState bypasses the router. The useEffect in useThreadChat would then set threadIdFromPath ('new') as the threadId, causing the LangGraph SDK to call POST /threads/new/history which returns HTTP 422 (Invalid thread ID: must be a UUID). This fix adds a guard to skip the threadId update when threadIdFromPath is the literal string 'new', preserving the already-correct UUID that was set when the thread was created. * fix(frontend): avoid using route new as thread id (#1967) Co-authored-by: luoxiao6645 <luoxiao6645@gmail.com> * Fix(subagent): Event loop conflict in SubagentExecutor.execute() (#1965) * Fix event loop conflict in SubagentExecutor.execute() When SubagentExecutor.execute() is called from within an already-running event loop (e.g., when the parent agent uses async/await), calling asyncio.run() creates a new event loop that conflicts with asyncio primitives (like httpx.AsyncClient) that were created in and bound to the parent loop.

fix(sandbox): add startup reconciliation to prevent orphaned container leaks (#1976)
* fix(sandbox): add startup reconciliation to prevent orphaned container leaks Sandbox containers were never cleaned up when the managing process restarted, because all lifecycle tracking lived in in-memory dictionaries. This adds startup reconciliation that enumerates running containers via `docker ps` and either destroys orphans (age > idle_timeout) or adopts them into the warm pool. Closes #1972 * fix(sandbox): address Copilot review — adopt-all strategy, improved error handling - Reconciliation now adopts all containers into warm pool unconditionally, letting the idle checker decide cleanup. Avoids destroying containers that another concurrent process may still be using. - list_running() logs stderr on docker ps failure and catches FileNotFoundError/OSError. - Signal handler test restores SIGTERM/SIGINT in addition to SIGHUP. - E2E test docstring corrected to match actual coverage scope. * fix(sandbox): address maintainer review — batch inspect, lock tightening, import hygiene - _reconcile_orphans(): merge check-and-insert into a single lock acquisition per container to eliminate the TOCTOU window. - list_running(): batch the per-container docker inspect into a single call. Total subprocess calls drop from 2N+1 to 2 (one ps + one batch inspect). Parse port and created_at from the inspect JSON payload. - Extract _parse_docker_timestamp() and _extract_host_port() as module-level pure helpers and test them directly. - Move datetime/json imports to module top level. - _make_provider_for_reconciliation(): document the __new__ bypass and the lockstep coupling to AioSandboxProvider.__init__. - Add assertion that list_running() makes exactly ONE inspect call. |

fix(models): resolve duplicate keyword argument error when reasoning_effort appears in both config and kwargs (#2017)
When a model config includes `reasoning_effort` as an extra YAML field
(ModelConfig uses `extra="allow"`), and the thinking-disabled code path
also injects `reasoning_effort="minimal"` into kwargs, the previous
`model_class(**kwargs, **model_settings_from_config)` call raises:
TypeError: got multiple values for keyword argument 'reasoning_effort'
Fix by merging the two dicts before instantiation, giving runtime kwargs
precedence over config values: `{**model_settings_from_config, **kwargs}`.
Fixes #1977

Fix(subagent): Event loop conflict in SubagentExecutor.execute() (#1965)
* Fix event loop conflict in SubagentExecutor.execute() When SubagentExecutor.execute() is called from within an already-running event loop (e.g., when the parent agent uses async/await), calling asyncio.run() creates a new event loop that conflicts with asyncio primitives (like httpx.AsyncClient) that were created in and bound to the parent loop. This fix detects if we're already in a running event loop, and if so, runs the subagent in a separate thread with its own isolated event loop to avoid conflicts.

fix(backend): make loop detection hash tool calls by stable keys (#1911)
* fix(backend): make loop detection hash tool calls by stable keys The loop detection middleware previously hashed full tool call arguments, which made repeated calls look different when only non-essential argument details changed. In particular, `read_file` calls with nearby line ranges could bypass repetition detection even when the agent was effectively reading the same file region again and again. - Hash tool calls using stable keys instead of the full raw args payload - Bucket `read_file` line ranges so nearby reads map to the same region key - Prefer stable identifiers such as `path`, `url`, `query`, or `command` before falling back to JSON serialization of args - Keep hashing order-independent so the same tool call set produces the same hash regardless of call order Fixes #1905 * fix(backend): harden loop detection hash normalization - Normalize and parse stringified tool args defensively - Expand stable key derivation to include pattern, glob, and cmd - Normalize reversed read_file ranges before bucketing Fixes #1905 * fix(backend): harden loop detection tool format * exclude write_file and str_replace from the stable-key path — writing different content to the same file shouldn't be flagged. --------- Co-authored-by: JeffJiang <for-eleven@hotmail.com> |

feat(sandbox): strengthen bash command auditing with compound splitting and expanded patterns (#1881)
* fix(sandbox): strengthen regex coverage in SandboxAuditMiddleware
Expand high-risk patterns from 6 to 13 and medium-risk from 4 to 6,
closing several bypass vectors identified by cross-referencing Claude
Code's BashSecurity validator chain against DeerFlow's threat model.
High-risk additions:
- Generalised pipe-to-sh (replaces narrow curl|sh rule)
- Targeted command substitution ($() / backtick with dangerous executables)
- base64 decode piped to execution
- Overwrite system binaries (/usr/bin/, /bin/, /sbin/)
- Overwrite shell startup files (~/.bashrc, ~/.profile, etc.)
- /proc/*/environ leakage
- LD_PRELOAD / LD_LIBRARY_PATH hijack
- /dev/tcp/ bash built-in networking
Medium-risk additions:
- sudo/su (no-op under Docker root, warn only)
- PATH= modification (long attack chain, warn only)
Design decisions:
- Command substitution uses targeted matching (curl/wget/bash/sh/python/
ruby/perl/base64) rather than blanket block to avoid false positives
on safe usage like $(date) or `whoami`.
- Skipped encoding/obfuscation checks (hex, octal, Unicode homoglyphs)
as ROI is low in Docker sandbox — LLMs don't generate encoded commands
and container isolation bounds the blast radius.
- Merged pip/pip3 into single pip3? pattern.
* feat(sandbox): compound command splitting and fork bomb detection
Split compound bash commands (&&, ||, ;) into sub-commands and classify
each independently — prevents dangerous commands hidden after safe
prefixes (e.g. "cd /workspace && rm -rf /") from bypassing detection.
- Add _split_compound_command() with shlex quote-aware splitting
- Add fork bomb detection patterns (classic and while-loop variants)
- Most severe verdict wins; block short-circuits
- 15 new tests covering compound commands, splitting, and fork bombs
* test(sandbox): add async tests for fork bomb and compound commands
Cover awrap_tool_call path for fork bomb detection (3 variants) and
compound command splitting (block/warn/pass scenarios).
* fix(sandbox): address Copilot review — no-whitespace operators, >>/etc/, whole-command scan
- _split_compound_command: replace shlex-based implementation with a
character-by-character quote/escape-aware scanner. shlex.split only
separates '&&' / '||' / ';' when they are surrounded by whitespace,
so payloads like 'rm -rf /&&echo ok' or 'safe;rm -rf /' bypassed the
previous splitter and therefore the per-sub-command classifier.
- _HIGH_RISK_PATTERNS: change r'>\s*/etc/' to r'>+\s*/etc/' so append
redirection ('>>/etc/hosts') is also blocked.
- _classify_command: run a whole-command high-risk scan *before*
splitting. Structural attacks like 'while true; do bash & done'
span multiple shell statements — splitting on ';' destroys the
pattern context, so the raw command must be scanned first.
- tests: add no-whitespace operator cases to TestSplitCompoundCommand
and test_compound_command_classification to lock in the bypass fix.

fix(subagents): add cooperative cancellation for subagent threads (#1873)
* fix(subagents): add cooperative cancellation for subagent threads
Subagent tasks run inside ThreadPoolExecutor threads with their own
event loop (asyncio.run). When a user clicks stop, RunManager cancels
the parent asyncio.Task, but Future.cancel() cannot terminate a running
thread and asyncio.Event does not propagate across event loops. This
causes subagent threads to keep executing (writing files, calling LLMs)
even after the user explicitly stops the run.
Fix: add a threading.Event (cancel_event) to SubagentResult and check
it cooperatively in _aexecute()'s astream iteration loop. On cancel,
request_cancel_background_task() sets the event, and the thread exits
at the next iteration boundary.
Changes:
- executor.py: Add cancel_event field to SubagentResult, check it in
_aexecute loop, set it on timeout, add request_cancel_background_task
- task_tool.py: Call request_cancel_background_task on CancelledError
* fix(subagents): guard cancel status and add pre-check before astream
- Only overwrite status to FAILED when still RUNNING, preserving
TIMED_OUT set by the scheduler thread.
- Add cancel_event pre-check before entering the astream loop so
cancellation is detected immediately when already signalled.
* fix(subagents): guard status updates with lock to prevent race condition
Wrap the check-and-set on result.status in _aexecute with
_background_tasks_lock so the timeout handler in execute_async
cannot interleave between the read and write.
* fix(subagents): add dedicated CANCELLED status for user cancellation
Introduce SubagentStatus.CANCELLED to distinguish user-initiated
cancellation from actual execution failures. Update _aexecute,
task_tool polling, cleanup terminal-status sets, and test fixtures.
* test(subagents): add cancellation tests and fix timeout regression test
- Add dedicated TestCooperativeCancellation test class with 6 tests:
- Pre-set cancel_event prevents astream from starting
- Mid-stream cancel_event returns CANCELLED immediately
- request_cancel_background_task() sets cancel_event correctly
- request_cancel on nonexistent task is a no-op
- Real execute_async timeout does not overwrite CANCELLED (deterministic
threading.Event sync, no wall-clock sleeps)
- cleanup_background_task removes CANCELLED tasks
- Add task_tool cancellation coverage:
- test_cancellation_calls_request_cancel: assert CancelledError path
calls request_cancel_background_task(task_id)
- test_task_tool_returns_cancelled_message: assert CANCELLED polling
branch emits task_cancelled event and returns expected message
- Fix pre-existing test infrastructure issue: add deerflow.sandbox.security
to _MOCKED_MODULE_NAMES (fixes ModuleNotFoundError for all executor tests)
- Add RUNNING guard to timeout handler in executor.py to prevent
TIMED_OUT from overwriting CANCELLED status
- Add cooperative cancellation granularity comment documenting that
cancellation is only detected at astream iteration boundaries

fix(memory): case-insensitive fact deduplication and positive reinforcement detection (#1804)
* fix(memory): case-insensitive fact deduplication and positive reinforcement detection Two fixes to the memory system: 1. _fact_content_key() now lowercases content before comparison, preventing semantically duplicate facts like "User prefers Python" and "user prefers python" from being stored separately. 2. Adds detect_reinforcement() to MemoryMiddleware (closes #1719), mirroring detect_correction(). When users signal approval ("yes exactly", "perfect", "完全正确", etc.), the memory updater now receives reinforcement_detected=True and injects a hint prompting the LLM to record confirmed preferences and behaviors with high confidence. Changes across the full signal path: - memory_middleware.py: _REINFORCEMENT_PATTERNS + detect_reinforcement() - queue.py: reinforcement_detected field in ConversationContext and add() - updater.py: reinforcement_detected param in update_memory() and update_memory_from_conversation(); builds reinforcement_hint alongside the existing correction_hint Tests: 11 new tests covering deduplication, hint injection, and signal detection (Chinese + English patterns, window boundary, conflict with correction). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(memory): address Copilot review comments on reinforcement detection - Tighten _REINFORCEMENT_PATTERNS: remove 很好, require punctuation/end-of-string boundaries on remaining patterns, split this-is-good into stricter variants - Suppress reinforcement_detected when correction_detected is true to avoid mixed-signal noise - Use casefold() instead of lower() for Unicode-aware fact deduplication - Add missing test coverage for reinforcement_detected OR merge and forwarding in queue --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> |

fix(middleware): handle list-type AIMessage.content in LoopDetectionMiddleware (#1823)
* fix: inject longTermBackground into memory prompt
The format_memory_for_injection function only processed recentMonths and
earlierContext from the history section, silently dropping longTermBackground.
The LLM writes longTermBackground correctly and it persists to memory.json,
but it was never injected into the system prompt — making the user's
long-term background invisible to the AI.
Add the missing field handling and a regression test.
* fix(middleware): handle list-type AIMessage.content in LoopDetectionMiddleware
LangChain AIMessage.content can be str | list. When using providers that
return structured content blocks (e.g. Anthropic thinking mode, certain
OpenAI-compatible gateways), content is a list of dicts like
[{"type": "text", "text": "..."}].
The hard_limit branch in _apply() concatenated content with a string via
(last_msg.content or "") + f"\n\n{_HARD_STOP_MSG}", which raises
TypeError when content is a non-empty list (list + str is invalid).
Add _append_text() static method that:
- Returns the text directly when content is None
- Appends a {"type": "text"} block when content is a list
- Falls back to string concatenation when content is a str
This is consistent with how other modules in the project already handle
list content (client.py._extract_text, memory_middleware, executor.py).
* test(middleware): add unit tests for _append_text and list content hard stop
Add regression tests to verify LoopDetectionMiddleware handles list-type
AIMessage.content correctly during hard stop:
- TestAppendText: unit tests for the new _append_text() static method
covering None, str, list (including empty list) content types
- TestHardStopWithListContent: integration tests verifying hard stop
works correctly with list content (Anthropic thinking mode), None
content, and str content
Requested by reviewer in PR #1823.
* fix(middleware): improve _append_text robustness and test isolation
- Add explicit isinstance(content, str) check with fallback for
unexpected types (coerce to str) to prevent TypeError on edge cases
- Deep-copy list content in _make_state() test helper to prevent
shared mutable references across test iterations
- Add test_unexpected_type_coerced_to_str: verify fallback for
non-str/list/None content types
- Add test_list_content_not_mutated_in_place: verify _append_text
does not modify the original list
* style: fix ruff format whitespace in test file

* feat(uploads): add pymupdf4llm PDF converter with auto-fallback and async offload - Introduce pymupdf4llm as an optional PDF converter with better heading detection and table preservation than MarkItDown - Auto mode: prefer pymupdf4llm when installed; fall back to MarkItDown when output is suspiciously sparse (image-based / scanned PDFs) - Sparsity check uses chars-per-page (< 50 chars/page) rather than an absolute threshold, correctly handling both short and long documents - Large files (> 1 MB) are offloaded to asyncio.to_thread() to avoid blocking the event loop (related: #1569) - Add UploadsConfig with pdf_converter field (auto/pymupdf4llm/markitdown) - Add pymupdf4llm as optional dependency: pip install deerflow-harness[pymupdf] - Add 14 unit tests covering sparsity heuristic, routing logic, and async path * fix(uploads): address Copilot review comments on PDF converter - Fix docstring: MIN_CHARS_PYMUPDF -> _MIN_CHARS_PER_PAGE (typo) - Fix file handle leak: wrap pymupdf.open in try/finally to ensure doc.close() - Fix silent fallback gap: _convert_pdf_with_pymupdf4llm now catches all conversion exceptions (not just ImportError), so encrypted/corrupt PDFs fall back to MarkItDown instead of propagating - Tighten type: pdf_converter field changed from str to Literal[auto|pymupdf4llm|markitdown] - Normalize config value: _get_pdf_converter() strips and lowercases the raw config string, warns and falls back to 'auto' on unknown values |

feat(uploads): inject document outline into agent context for converted files (#1738)
* feat(uploads): inject document outline into agent context for converted files
Extract headings from converted .md files and inject them into the
<uploaded_files> context block so the agent can navigate large documents
by line number before reading.
- Add `extract_outline()` to `file_conversion.py`: recognises standard
Markdown headings (#/##/###) and SEC-style bold structural headings
(**ITEM N. BUSINESS**, **PART II**); caps at 50 entries; excludes
cover-page boilerplate (WASHINGTON DC, CURRENT REPORT, SIGNATURES)
- Add `_extract_outline_for_file()` helper in `uploads_middleware.py`:
looks for a sibling `.md` file produced by the conversion pipeline
- Update `UploadsMiddleware._create_files_message()` to render the outline
under each file entry with `L{line}: {title}` format and a `read_file`
prompt for range-based reading
- Tests: 10 new tests for `extract_outline()`, 4 new tests for outline
injection in `UploadsMiddleware`; existing test updated for new `outline`
field in `uploaded_files` state
Partially addresses #1647 (agent ignores uploaded files).
* fix(uploads): stream outline file reads and strip inline bold from heading titles
- Switch extract_outline() from read_text().splitlines() to open()+line iteration
so large converted documents are not loaded into memory on every agent turn;
exits as soon as MAX_OUTLINE_ENTRIES is reached (Copilot suggestion)
- Strip **...** wrapper from standard Markdown heading titles before appending
to outline so agent context stays clean (e.g. "## **Overview**" → "Overview")
(Copilot suggestion)
- Remove unused pathlib.Path import and fix import sort order in test_file_conversion.py
to satisfy ruff CI lint
* fix(uploads): show truncation hint when outline exceeds MAX_OUTLINE_ENTRIES
When extract_outline() hits the cap it now appends a sentinel entry
{"truncated": True} instead of silently dropping the rest of the headings.
UploadsMiddleware reads the sentinel and renders a hint line:
... (showing first 50 headings; use `read_file` to explore further)
Without this the agent had no way to know the outline was incomplete and
would treat the first 50 headings as the full document structure.
* fix(uploads): fall back to configurable.thread_id when runtime.context lacks thread_id
runtime.context does not always carry thread_id (depends on LangGraph
invocation path). ThreadDataMiddleware already falls back to
get_config().configurable.thread_id — apply the same pattern so
UploadsMiddleware can resolve the uploads directory and attach outlines
in all invocation paths.
* style: apply ruff format

fix: guarantee END sentinel delivery when stream bridge queue is full (#1695)
When MemoryStreamBridge queue reaches capacity, publish_end() previously used the same 30s timeout + drop strategy as regular events. If the END sentinel was dropped, subscribe() would loop forever waiting for it, causing the SSE connection to hang indefinitely and leaking _queues and _counters resources for that run_id. Changes: - publish_end() now evicts oldest regular events when queue is full to guarantee END sentinel delivery — the sentinel is the only signal that allows subscribers to terminate - Added per-run drop counters (_dropped_counts) with dropped_count() and dropped_total properties for observability - cleanup() and close() now clear drop counters - publish() logs total dropped count per run for easier debugging Tests: - test_end_sentinel_delivered_when_queue_full: verifies END arrives even with a completely full queue - test_end_sentinel_evicts_oldest_events: verifies eviction behavior - test_end_sentinel_no_eviction_when_space_available: no side effects when queue has room - test_concurrent_tasks_end_sentinel: 4 concurrent producer/consumer pairs all terminate properly - test_dropped_count_tracking, test_dropped_total, test_cleanup_clears_dropped_counts, test_close_clears_dropped_counts: drop counter coverage Closes #1689 Co-authored-by: voidborne-d <voidborne-d@users.noreply.github.com> |

fix: use SystemMessage+HumanMessage for follow-up question generation (#1751)
* fix: use SystemMessage+HumanMessage for follow-up question generation (fixes #1697) Some models (e.g. MiniMax-M2.7) require the system prompt and user content to be passed as separate message objects rather than a single combined string.

feat(sandbox): truncate oversized bash and read_file tool outputs (#1677)
* feat(sandbox): truncate oversized bash and read_file tool outputs Long tool outputs (large directory listings, multi-MB source files) can overflow the model's context window. Two new configurable limits: - bash_output_max_chars (default 20000): middle-truncates bash output, preserving both head and tail so stderr at the end is not lost - read_file_output_max_chars (default 50000): head-truncates file output with a hint to use start_line/end_line for targeted reads Both limits are enforced at the tool layer (sandbox/tools.py) rather than middleware, so truncation is guaranteed regardless of call path. Setting either limit to 0 disables truncation entirely. Measured: read_file on a 250KB source file drops from 63,698 tokens to 19,927 tokens (69% reduction) with the default limit. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(tests): remove unused pytest import and fix import sort order * style: apply ruff format to sandbox/tools.py * refactor(sandbox): address Copilot review feedback on truncation feature - strict hard cap: while-loop ensures result (including marker) ≤ max_chars - max_chars=0 now returns "" instead of original output - get_app_config() wrapped in try/except with fallback to defaults - sandbox_config.py: add ge=0 validation on truncation limit fields - config.example.yaml: bump config_version 4→5 - tests: add len(result) <= max_chars assertions, edge-case (max=0, small max, various sizes) tests; fix skipped-count test for strict hard cap * refactor(sandbox): replace while-loop truncation with fixed marker budget Use a pre-allocated constant (_MARKER_MAX_LEN) instead of a convergence loop to ensure result <= max_chars. Simpler, safer, and skipped-char count in the marker is now an exact predictable value. * refactor(sandbox): compute marker budget dynamically instead of hardcoding * fix(sandbox): make max_chars=0 disable truncation instead of returning empty string --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: JeffJiang <for-eleven@hotmail.com> |

fix: avoid treating Feishu file paths as commands (#1654)
Feishu channel classified any slash-prefixed text (including absolute paths such as /mnt/user-data/...) as a COMMAND, causing them to be misrouted through the command pipeline instead of the chat pipeline. Fix by introducing a shared KNOWN_CHANNEL_COMMANDS frozenset in app/channels/commands.py — the single authoritative source for the set of supported slash commands. Both the Feishu inbound parser and the ChannelManager's unknown-command reply now derive from it, so adding or removing a command requires only one edit. Changes: - app/channels/commands.py (new): defines KNOWN_CHANNEL_COMMANDS - app/channels/feishu.py: replace local KNOWN_FEISHU_COMMANDS with the shared constant; _is_feishu_command() now gates on it - app/channels/manager.py: import KNOWN_CHANNEL_COMMANDS and use it in the unknown-command fallback reply so the displayed list stays in sync - tests/test_feishu_parser.py: parametrize over every entry in KNOWN_CHANNEL_COMMANDS (each must yield msg_type=command) and add parametrized chat cases for /unknown, absolute paths, etc. Made with Cursor Made-with: Cursor Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(gateway): forward assistant_id as agent_name in build_run_config (#1667)
* fix(gateway): forward assistant_id as agent_name in build_run_config Fixes #1644 When the LangGraph Platform-compatible /runs endpoint receives a custom assistant_id (e.g. 'finalis'), the Gateway's build_run_config() silently ignored it — configurable['agent_name'] was never set, so make_lead_agent fell through to the default lead agent and SOUL.md was never loaded. Root cause (introduced in #1403): resolve_agent_factory() correctly falls back to make_lead_agent for all assistant_id values, but build_run_config() had no assistant_id parameter and never injected configurable['agent_name']. The full call chain: POST /runs (assistant_id='finalis') → resolve_agent_factory('finalis') # returns make_lead_agent ✓ → build_run_config(thread_id, ...) # no agent_name injected ✗ → make_lead_agent(config) → cfg.get('agent_name') → None → load_agent_soul(None) → base SOUL.md (doesn't exist) → None Fix: - Add keyword-only parameter to build_run_config(). - When assistant_id is set and differs from 'lead_agent', inject it as configurable['agent_name'] (matching the channel manager's existing _resolve_run_params() logic for IM channels). - Honour an explicit configurable['agent_name'] in the request body; assistant_id mapping only fills the gap when it is absent. - Remove stale log-only branch from resolve_agent_factory(); update docstring to explain the factory/configurable split. Tests added (test_gateway_services.py): - Custom assistant_id injects configurable['agent_name'] - 'lead_agent' assistant_id does NOT inject agent_name - None assistant_id does NOT inject agent_name - Explicit configurable['agent_name'] in request is not overwritten - resolve_agent_factory returns make_lead_agent for all inputs * style: format with ruff * fix: validate and normalize assistant_id to prevent path traversal Addresses Copilot review: strip/lowercase/replace underscores and reject names that don't match [a-z0-9-]+, consistent with ChannelManager._normalize_custom_agent_name(). --------- Co-authored-by: voidborne-d <voidborne-d@users.noreply.github.com> |

feat(gateway): implement LangGraph Platform API in Gateway, replace langgraph-cli (#1403)
* feat(gateway): implement LangGraph Platform API in Gateway, replace langgraph-cli
Implement all core LangGraph Platform API endpoints in the Gateway,
allowing it to fully replace the langgraph-cli dev server for local
development. This eliminates a heavyweight dependency and simplifies
the development stack.
Changes:
- Add runs lifecycle endpoints (create, stream, wait, cancel, join)
- Add threads CRUD and search endpoints
- Add assistants compatibility endpoints (search, get, graph, schemas)
- Add StreamBridge (in-memory pub/sub for SSE) and async provider
- Add RunManager with atomic create_or_reject (eliminates TOCTOU race)
- Add worker with interrupt/rollback cancel actions and runtime context injection
- Route /api/langgraph/* to Gateway in nginx config
- Skip langgraph-cli startup by default (SKIP_LANGGRAPH_SERVER=0 to restore)
- Add unit tests for RunManager, SSE format, and StreamBridge
* fix: drain bridge queue on client disconnect to prevent backpressure
When on_disconnect=continue, keep consuming events from the bridge
without yielding, so the worker is not blocked by a full queue.
Only on_disconnect=cancel breaks out immediately.

* fix: address review comments on gateway LangGraph API
- Mount runs.py router in app.py (missing include_router)
- Normalize interrupt_before/after "*" to node list before run_agent()
- Use entry.id for SSE event ID instead of counter
- Drain bridge queue on disconnect when on_disconnect=continue
- Reuse serialization helper in wait_run() for consistent wire format
- Reject unsupported multitask_strategy with 400
- Remove SKIP_LANGGRAPH_SERVER fallback, always use Gateway
* feat: extract app.state access into deps.py

StreamBridge, checkpointer) held in app.state into a shared utility,
reducing repeated access patterns across router modules.

- Enable official LangGraph dev server for local development workflow
- Decouple runtime components from agents package for better separation
- Provide gateway-backed fallback route when dev server is skipped
- Simplify lifecycle management using context manager in gateway
* feat(runtime): add Store providers with auto-backend selection
- Add async_provider.py and provider.py under deerflow/runtime/store/
- Support memory, sqlite, postgres backends matching checkpointer config
- Integrate into FastAPI lifespan via AsyncExitStack in deps.py
- Replace hardcoded InMemoryStore with config-driven factory
* refactor(gateway): migrate thread management from checkpointer to Store and resolve multiple endpoint failures
- Add Store-backed CRUD helpers (_store_get, _store_put, _store_upsert)
- Replace checkpoint-scanning search with two-phase strategy:
phase 1 reads Store (O(threads)), phase 2 backfills from checkpointer
for legacy/LangGraph Server threads with lazy migration
- Extend Store record schema with values field for title persistence
- Sync thread title from checkpoint to Store after run completion
- Fix /threads/{id}/runs/{run_id}/stream 405 by accepting both
GET and POST methods; POST handles interrupt/rollback actions
- Fix /threads/{id}/state 500 by separating read_config and
write_config, adding checkpoint_ns to configurable, and
shallow-copying checkpoint/metadata before mutation
- Sync title to Store on state update for immediate search reflection
- Move _upsert_thread_in_store into services.py, remove duplicate logic
- Add _sync_thread_title_after_run: await run task, read final
checkpoint title, write back to Store record
- Spawn title sync as background task from start_run when Store exists
* refactor(runtime): deduplicate store and checkpointer provider logic
Extract _ensure_sqlite_parent_dir() helper into checkpointer/provider.py
and use it in all three places that previously inlined the same mkdir logic.
Consolidate duplicate error constants in store/async_provider.py by importing
from store/provider.py instead of redefining them.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* refactor(runtime): move SQLite helpers to runtime/store, checkpointer imports from store
_resolve_sqlite_conn_str and _ensure_sqlite_parent_dir now live in
runtime/store/provider.py. agents/checkpointer/provider and
agents/checkpointer/async_provider import from there, reversing the
previous dependency direction (store → checkpointer becomes
checkpointer → store).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* refactor(runtime): extract SQLite helpers into runtime/store/_sqlite_utils.py
Move resolve_sqlite_conn_str and ensure_sqlite_parent_dir out of
checkpointer/provider.py into a dedicated _sqlite_utils module.
Functions are now public (no underscore prefix), making cross-module
imports semantically correct. All four provider files import from
the single shared location.

* fix(gateway): use adelete_thread to fully remove thread checkpoints on delete
AsyncSqliteSaver has no adelete method — the previous hasattr check
always evaluated to False, silently leaving all checkpoint rows in the
database. Switch to adelete_thread(thread_id) which deletes every
checkpoint and pending-write row for the thread across all namespaces
(including sub-graph checkpoints).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(gateway): remove dead bridge_cm/ckpt_cm code and fix StrEnum lint
app.py had unreachable code after the async-with lifespan refactor:
bridge_cm and ckpt_cm were referenced but never defined (F821), and
the channel service startup/shutdown was outside the langgraph_runtime
block so it never ran. Move channel service lifecycle inside the
async-with block where it belongs.
Replace str+Enum inheritance in RunStatus and DisconnectMode with
StrEnum as suggested by UP042.

fix: promote deferred tools after tool_search returns schema (#1570)
* fix: promote matched tools from deferred registry after tool_search returns schema After tool_search returns a tool's full schema, the tool is promoted (removed from the deferred registry) so DeferredToolFilterMiddleware stops filtering it from bind_tools on subsequent LLM calls. Without this, deferred tools are permanently filtered — the LLM gets the schema from tool_search but can never invoke the tool because the middleware keeps stripping it. Fixes #1554 * test: add promote() and tool_search promotion tests Tests cover: - promote removes tools from registry - promote nonexistent/empty is no-op - search returns nothing after promote - middleware passes promoted tools through - tool_search auto-promotes matched tools (select + keyword) * fix: address review — lint blank line + empty registry guard - Add missing blank line between FakeRequest methods (E301) - Use 'if not registry' to handle empty registries consistently --------- Co-authored-by: d 🔹 <258577966+voidborne-d@users.noreply.github.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat(sandbox): add SandboxAuditMiddleware for bash command security auditing (#1532)
* feat(sandbox): add SandboxAuditMiddleware for bash command security auditing Addresses the LocalSandbox escape vector reported in #1224 where bash tool calls can execute destructive commands against the host filesystem. - Add SandboxAuditMiddleware with three-tier command classification: - High-risk (block): rm -rf /, curl|bash, dd if=, mkfs, /etc/shadow access - Medium-risk (warn): pip install, apt install, chmod 777 - Safe (pass): normal workspace operations - Register middleware after GuardrailMiddleware in _build_runtime_middlewares, applied to both lead agent and subagents - Structured audit log via standard logger (visible in langgraph.log) - Medium-risk commands execute but append a warning to the tool result, allowing the LLM to self-correct without blocking legitimate workflows - High-risk commands return an error ToolMessage without calling the handler, so the agent loop continues gracefully * fix(lint): sort imports in test_sandbox_audit_middleware * refactor(sandbox-audit): address Copilot review feedback (3/5/6) - Fix class docstring to match implementation: medium-risk commands are executed with a warning appended (not rejected), and cwd anchoring note removed (handled in a separate PR) - Remove capsys.disabled() from benchmark test to avoid CI log noise; keep assertions for recall/precision targets - Remove misleading 'cwd fix' from test module docstring * test(sandbox-audit): add async tests for awrap_tool_call * fix(sandbox-audit): address Copilot review feedback (1/2) - Narrow rm high-risk regex to only block truly destructive targets (/, /*, ~, ~/*, /home, /root); legitimate workspace paths like /mnt/user-data/ are no longer false-positived - Handle list-typed ToolMessage content in _append_warn_to_result; append a text block instead of str()-ing the list to avoid breaking structured content normalization * style: apply ruff format to sandbox_audit_middleware files * fix(sandbox-audit): update benchmark comment to match assert-based implementation --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(sandbox): anchor relative paths to thread workspace in local mode (#1522)
* fix(task_tool): fallback to configurable thread_id when context is missing task_tool only read thread_id from runtime.context, but when invoked via LangGraph Server, thread_id lives in config.configurable instead. Add the same fallback that ThreadDataMiddleware uses (PR #1237). Fixes subagent execution failure: 'Thread ID is required in runtime context or config.configurable' * remove debug logging from task_tool * fix(sandbox): anchor relative paths to thread workspace in local mode In local sandbox mode, bash commands using relative paths were resolved against the langgraph server process cwd (backend/) instead of the per-thread workspace directory. This allowed relative-path writes to escape the thread isolation boundary. Root cause: validate_local_bash_command_paths and replace_virtual_paths_in_command only process absolute paths (scanning for '/' prefix). Relative paths pass through untouched and inherit the process cwd at subprocess.run time. Fix: after virtual path translation, prepend `cd {workspace} &&` to anchor the shell's cwd to the thread-isolated workspace directory before execution. shlex.quote() ensures paths with spaces or special characters are handled safely. This mirrors the approach used by OpenHands (fixed cwd at execution layer) and is the correct fix for local mode where each subprocess.run is an independent process with no persistent shell session. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(sandbox): extract _apply_cwd_prefix and add unit tests Extract the workspace cd-prefix logic from bash_tool into a dedicated _apply_cwd_prefix() helper so it can be unit-tested in isolation. Add four tests covering: normal prefix, no thread_data, missing workspace_path, and paths with spaces (shlex.quote). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * revert: remove unrelated configurable thread_id fallback from sandbox/tools.py This change belongs in a separate PR.

fix(oauth): inject billing header for Claude oAuth Models (#1442)
* fix(oauth): inject billing header for non-Haiku model access The Anthropic Messages API requires a billing identification block in the system prompt when using Claude Code OAuth tokens (sk-ant-oat*) to access non-Haiku models (Opus, Sonnet). Without it, the API returns a generic 400 "Error" with no actionable detail. This was discovered by intercepting Claude Code CLI requests — the CLI injects an `x-anthropic-billing-header` text block as the first system prompt entry on every request. Third-party consumers of the same OAuth tokens must do the same. Changes: - Add `_apply_oauth_billing()` to `ClaudeChatModel` that prepends the billing header block to the system prompt when `_is_oauth` is True - Add `metadata.user_id` with device/session identifiers (required by the API alongside the billing header) - Called from `_get_request_payload()` before prompt caching runs Verified with Claude Max OAuth tokens against all three model tiers: - claude-opus-4-6: 200 OK - claude-sonnet-4-6: 200 OK - claude-haiku-4-5-20251001: 200 OK (was already working) Closes #1245 * fix(oauth): address review feedback on billing header injection - Make OAUTH_BILLING_HEADER configurable via ANTHROPIC_BILLING_HEADER env var - Normalize billing block to always be first in system list (strip + reinsert) - Guard metadata with isinstance check for non-dict values - Replace os.uname() with socket.gethostname() for Windows compat - Fix docstrings to say "all OAuth requests" instead of "non-Haiku" - Move inline imports to module level (fixes ruff I001) - Add 9 unit tests for _apply_oauth_billing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |

fix(LLM): fixing Gemini thinking + tool calls via OpenAI gateway (#1180) (#1205)
* fix(LLM): fixing Gemini thinking + tool calls via OpenAI gateway (#1180) When using Gemini with thinking enabled through an OpenAI-compatible gateway, the API requires that fields on thinking content blocks are preserved and echoed back verbatim in subsequent requests. Standard silently drops these signatures when serializing messages, causing HTTP 400 errors: Changes: - Add PatchedChatOpenAI adapter that re-injects signed thinking blocks into request payloads, preserving the signature chain across multi-turn conversations with tool calls. - Support two LangChain storage patterns: additional_kwargs.thinking_blocks and content list. - Add 11 unit tests covering signed/unsigned blocks, storage patterns, edge cases, and precedence rules. - Update config.example.yaml with Gemini + thinking gateway example. - Update CONFIGURATION.md with detailed guidance and error explanation.

feat(harness): integration ACP agent tool (#1344)
* refactor: extract shared utils to break harness→app cross-layer imports Move _validate_skill_frontmatter to src/skills/validation.py and CONVERTIBLE_EXTENSIONS + convert_file_to_markdown to src/utils/file_conversion.py. This eliminates the two reverse dependencies from client.py (harness layer) into gateway/routers/ (app layer), preparing for the harness/app package split. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: split backend/src into harness (deerflow.*) and app (app.*) Physically split the monolithic backend/src/ package into two layers: - **Harness** (`packages/harness/deerflow/`): publishable agent framework package with import prefix `deerflow.*`. Contains agents, sandbox, tools, models, MCP, skills, config, and all core infrastructure. - **App** (`app/`): unpublished application code with import prefix `app.*`. Contains gateway (FastAPI REST API) and channels (IM integrations). Key changes: - Move 13 harness modules to packages/harness/deerflow/ via git mv - Move gateway + channels to app/ via git mv - Rename all imports: src.* → deerflow.* (harness) / app.* (app layer) - Set up uv workspace with deerflow-harness as workspace member - Update langgraph.json, config.example.yaml, all scripts, Docker files - Add build-system (hatchling) to harness pyproject.toml - Add PYTHONPATH=. to gateway startup commands for app.* resolution - Update ruff.toml with known-first-party for import sorting - Update all documentation to reflect new directory structure Boundary rule enforced: harness code never imports from app. All 429 tests pass. Lint clean. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: add harness→app boundary check test and update docs Add test_harness_boundary.py that scans all Python files in packages/harness/deerflow/ and fails if any `from app.*` or `import app.*` statement is found. This enforces the architectural rule that the harness layer never depends on the app layer. Update CLAUDE.md to document the harness/app split architecture, import conventions, and the boundary enforcement test. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add config versioning with auto-upgrade on startup When config.example.yaml schema changes, developers' local config.yaml files can silently become outdated. This adds a config_version field and auto-upgrade mechanism so breaking changes (like src.* → deerflow.* renames) are applied automatically before services start. - Add config_version: 1 to config.example.yaml - Add startup version check warning in AppConfig.from_file() - Add scripts/config-upgrade.sh with migration registry for value replacements - Add `make config-upgrade` target - Auto-run config-upgrade in serve.sh and start-daemon.sh before starting services - Add config error hints in service failure messages Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix comments * fix: update src.* import in test_sandbox_tools_security to deerflow.* Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: handle empty config and search parent dirs for config.example.yaml Address Copilot review comments on PR #1131: - Guard against yaml.safe_load() returning None for empty config files - Search parent directories for config.example.yaml instead of only looking next to config.yaml, fixing detection in common setups Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: correct skills root path depth and config_version type coercion - loader.py: fix get_skills_root_path() to use 5 parent levels (was 3) after harness split, file lives at packages/harness/deerflow/skills/ so parent×3 resolved to backend/packages/harness/ instead of backend/ - app_config.py: coerce config_version to int() before comparison in _check_config_version() to prevent TypeError when YAML stores value as string (e.g. config_version: "1") - tests: add regression tests for both fixes Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: update test imports from src.* to deerflow.*/app.* after harness refactor Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(harness): add tool-first ACP agent invocation (#37) * feat(harness): add tool-first ACP agent invocation * build(harness): make ACP dependency required * fix(harness): address ACP review feedback * feat(harness): decouple ACP agent workspace from thread data ACP agents (codex, claude-code) previously used per-thread workspace directories, causing path resolution complexity and coupling task execution to DeerFlow's internal thread data layout. This change: - Replace _resolve_cwd() with a fixed _get_work_dir() that always uses {base_dir}/acp-workspace/, eliminating virtual path translation and thread_id lookups - Introduce /mnt/acp-workspace virtual path for lead agent read-only access to ACP agent output files (same pattern as /mnt/skills) - Add security guards: read-only validation, path traversal prevention, command path allowlisting, and output masking for acp-workspace - Update system prompt and tool description to guide LLM: send self-contained tasks to ACP agents, copy results via /mnt/acp-workspace - Add 11 new security tests for ACP workspace path handling Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor(prompt): inject ACP section only when ACP agents are configured The ACP agent guidance in the system prompt is now conditionally built by _build_acp_section(), which checks get_acp_agents() and returns an empty string when no ACP agents are configured. This avoids polluting the prompt with irrelevant instructions for users who don't use ACP. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix lint * fix(harness): address Copilot review comments on sandbox path handling and ACP tool - local_sandbox: fix path-segment boundary bug in _resolve_path (== or startswith +"/") and add lookahead in _resolve_paths_in_command regex to prevent /mnt/skills matching inside /mnt/skills-extra - local_sandbox_provider: replace print() with logger.warning(..., exc_info=True) - invoke_acp_agent_tool: guard getattr(option, "optionId") with None default + continue; move full prompt from INFO to DEBUG level (truncated to 200 chars) - sandbox/tools: fix _get_acp_workspace_host_path docstring to match implementation; remove misleading "read-only" language from validate_local_bash_command_paths Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(acp): thread-isolated workspaces, permission guardrail, and ContextVar registry P1.1 – ACP workspace thread isolation - Add `Paths.acp_workspace_dir(thread_id)` for per-thread paths - `_get_work_dir(thread_id)` in invoke_acp_agent_tool now uses `{base_dir}/threads/{thread_id}/acp-workspace/`; falls back to global workspace when thread_id is absent or invalid - `_invoke` extracts thread_id from `RunnableConfig` via `Annotated[RunnableConfig, InjectedToolArg]` - `sandbox/tools.py`: `_get_acp_workspace_host_path(thread_id)`, `_resolve_acp_workspace_path(path, thread_id)`, and all callers (`replace_virtual_paths_in_command`, `mask_local_paths_in_output`, `ls_tool`, `read_file_tool`) now resolve ACP paths per-thread P1.2 – ACP permission guardrail - New `auto_approve_permissions: bool = False` field in `ACPAgentConfig` - `_build_permission_response(options, *, auto_approve: bool)` now defaults to deny; only approves when `auto_approve=True` - Document field in `config.example.yaml` P2 – Deferred tool registry race condition - Replace module-level `_registry` global with `contextvars.ContextVar` - Each asyncio request context gets its own registry; worker threads inherit the context automatically via `loop.run_in_executor` - Expose `get_deferred_registry` / `set_deferred_registry` / `reset_deferred_registry` helpers Tests: 831 pass (57 for affected modules, 3 new tests) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sandbox): mount /mnt/acp-workspace in docker sandbox container The AioSandboxProvider was not mounting the ACP workspace into the sandbox container, so /mnt/acp-workspace was inaccessible when the lead agent tried to read ACP results in docker mode. Changes: - `ensure_thread_dirs`: also create `acp-workspace/` (chmod 0o777) so the directory exists before the sandbox container starts — required for Docker volume mounts - `_get_thread_mounts`: add read-only `/mnt/acp-workspace` mount using the per-thread host path (`host_paths.acp_workspace_dir(thread_id)`) - Update stale CLAUDE.md description (was "fixed global workspace") Tests: `test_aio_sandbox_provider.py` (4 new tests) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(lint): remove unused imports in test_aio_sandbox_provider Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix config --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |

test: add unit tests for TodoMiddleware (#1307)
* test: add unit tests for TodoMiddleware Cover context-loss detection logic: - _todos_in_messages and _reminder_in_messages helpers - _format_todos formatting - Reminder injection when write_todos truncated - No-op when todos visible or reminder already present - abefore_model async delegation * test: fix event loop error in todo middleware async test Use asyncio.run() instead of get_event_loop().run_until_complete() to avoid RuntimeError on Python 3.12 where no default event loop exists in the main thread. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

test: add unit tests for DanglingToolCallMiddleware (#1305)
* test: add unit tests for DanglingToolCallMiddleware Cover message patching logic for dangling tool calls: - No-op when all tool calls have responses - Synthetic ToolMessage insertion at correct positions - Mixed responded/dangling scenarios - wrap_model_call and awrap_model_call integration * test: fix async tests and strengthen override assertions - Use @pytest.mark.anyio + async def instead of deprecated asyncio.get_event_loop().run_until_complete() (fixes Py3.12 CI failure) - Assert that override() receives the correct patched messages kwarg in both wrap_model_call and awrap_model_call tests --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |
