fix(channels): isolate per-message failures in WeChat poll loop (#4231)
_poll_loop persisted the long-poll cursor (get_updates_buf) for the whole getupdates batch immediately on receipt, then iterated data["msgs"] with no per-message error handling. If any single message's processing raised (e.g. an attachment that fails to decrypt), the for loop aborted and every message after the failing one in that batch was never handled -- but since the cursor had already advanced past the whole batch, the next poll would never re-fetch them. The loss was silent and permanent, not a delay. Fix is two parts: - Wrap each _handle_update call in its own try/except (re-raising CancelledError) so one bad message is logged and skipped instead of aborting the rest of the batch. - Move the cursor advance/persist to after the per-message loop instead of before it, so a hard crash mid-batch leaves the cursor unmoved. Worst case becomes re-fetching and re-processing the batch on restart, not silently skipping messages that were never actually handled. Regression test drives the real _handle_update over a 3-message batch where the middle message is a WeChat image item with deliberately non-block-aligned "encrypted" bytes, so decryption raises a genuine cryptography ValueError (the same failure shape a corrupt real attachment would produce). Confirms the first and third messages both still reach the bus, the failure is logged with the message id, and the persisted cursor reflects the fully-attempted batch. |

fix(tui): interrupt an active run before /quit exits (#4235)
_handle_builtin's "quit" branch called self.exit() unconditionally, unlike action_interrupt (Ctrl+C), which checks self._streaming and interrupts before any teardown. During an active run, /quit tore the app down while the worker thread was still live; the next call_from_thread call from that orphaned thread then failed silently (the app's loop is gone), quietly abandoning the in-flight turn and any post-run persistence such as the thread title. Mirror action_interrupt's check: if self._streaming, run the same interrupt/cleanup path before calling self.exit(). /quit still always exits -- it now just does so safely. Adds a regression test using a fake client that blocks mid-stream (a real worker thread genuinely stuck, not a hand-flipped flag) to catch /quit during a run, plus a Ctrl+C contrast test under the same setup. |

fix(channels): don't treat a bare "connect" as a bind command (#4251)
`extract_connect_code` matched `command in {"/connect", "connect"}`, so any
message whose first word is the ordinary English word "connect" was parsed as
`/connect <code>` and its next word swallowed as a one-time bind code. For
example `extract_connect_code("connect the database to the api")` returned
`"the"` instead of `None`, meaning a normal chat message never reached the
agent and instead attempted a channel bind.
Every other channel control command requires a leading slash:
`is_known_channel_command` only matches `/`-prefixed tokens and
`KNOWN_CHANNEL_COMMANDS` holds only slash forms (`/goal`, `/new`, ...). The
docstrings and AGENTS.md advertise only `/connect <code>`. The bare alias was
inconsistent with all of that and produced the false-positive bind.
Match only `/connect`. The `.lower()` keeps it case-insensitive (`/Connect`)
and the mention-prefix handling from #4222 is unaffected, so
`@bot /connect <code>` still binds.

feat(tool):Add structured synopsis for oversized tool output previews (#3377)
* Improve tool output preview synopsis * Add JSON path anchors to tool output synopsis * Fix JSON synopsis line anchors * fix(synopsis): tighten detectors and fix CSV first-row join Address review feedback from @willem-bd on PR #3377. Detectors: - _looks_yaml now requires >=3 key-shaped lines and refuses bare uppercase-tag lines ('INFO: ...', 'ERROR: ...') that look like log lines and would round-trip into a flat string dict via safe_load. Previously a 200-line log file was classified as 'YAML object with 3 top-level keys' and lost every line, count, and middle signal. - _try_yaml refuses payloads that safe_load collapses to a dict of all strings (the shape tracebacks and log lines collapse into). - _try_table applies the header-must-look-like-identifiers and minimum-row-count guards only to TSV, since the same safeguards would reject legitimate small CSVs. Refuses tab-indented bash output, ls -l listings, and tree dumps. Rendering: - CSV first data row is now rendered as a key=value list joined by ' | ' (e.g. 'name=Ada | description="a fine, brilliant logician" | score=98'). The previous delimiter.join(rows[1]) silently re-split cells that contained the delimiter inside a quoted cell, which made the synopsis report a 3-column table as 5 columns and misled the model about column count and content. Text summary: - _summarize_text now omits the closing excerpt entirely when the input is shorter than 2 * _TEXT_EXCERPT_CHARS, since the previous opener/closer slices overlapped and duplicated text for short inputs (build_tool_output_synopsis is reachable directly from tests and other callers that pass small inputs). Tests: - Update test_table_preview_extracts_columns to assert the new key=value list format. * fix(synopsis): drop JSON path line/byte offset hints The path-location hint was computed by string-searching for the quoted key in the original content and reporting its byte offset and line number. This anchors at the first textual occurrence of the key string, which is wrong when the key also appears as a value earlier in the document, or when the same key recurs at multiple depths. With nested paths the anchor drifts further on every step because the search cursor is advanced past each previous match. Concrete cases: content = '{"label": "items", "items": {"id": 1}}' _json_path_location(content, ['items']) -> ' (line 1, byte offset 10)' # the value, not the key content = '{"data": {"info": 1, "data": {"info": 2}}}' _json_path_location(content, ['data','data','info']) -> ' (line 1, byte offset 30)' # the inner first 'info', not the second The synopsis instructed the model to 'Start near the line hints above when present', so a wrong anchor would send read_file into the wrong region of the persisted .tool-results file. Drop the hint entirely. The path itself ('$.data.items') is already useful navigation; the agent uses read_file with start_line based on its own judgement of where the relevant slice is. Tests: - Update test_json_preview_reports_nested_paths to assert no 'line ' or 'byte offset ' appears in the body before the Access section. - Rename test_json_line_hints_use_original_content_offsets to test_json_paths_are_emitted_without_line_hints and invert the assertions to check the hints are absent. * fix(synopsis): bound _scalar_examples recursion depth Mirror the _JSON_STRUCTURE_DEPTH cap used by _json_container_paths and _json_shape so that deeply nested JSON cannot trigger RecursionError inside build_tool_output_synopsis. In ToolOutputBudgetMiddleware.awrap_tool_call the synopsis is built inside asyncio.to_thread(_patch_result, ...); a RecursionError would surface as a tool-call failure and the user would lose the entire output. 300-level nested JSON is well inside what an attacker-controlled MCP tool, a JSON-RPC-over-JSON-RPC chain, or a buggy serializer can produce. * feat(synopsis): restore inline raw head/tail sample The synopsis-only preview silently dropped the raw head/tail bytes that preview_head_chars / preview_tail_chars used to inline. For text/code/log outputs the agent lost first/last KB of the actual content and had to issue a follow-up read_file round-trip to see the trailing region (last paragraph of a fetched article, final error line in a traceback, closing diagnostics of a bash run). Restore an inline 'Raw sample (head + tail)' section in the preview. The section is composed by slicing head_chars from the start and tail_chars from the end of the content (with a '...' separator between them, and the tail suppressed when it would overlap the head). For binary-like output, the synopsis's own sample is reused unchanged. This makes preview_head_chars / preview_tail_chars operational again for every kind except binary, which already had a sample channel. Tests: - Rename test_json_preview_extracts_structure_instead_of_head_tail to test_json_preview_includes_structure_and_raw_sample and assert the raw sample section is present and the payload is reachable in the head slice. * test(synopsis): add regression tests for willem-bd review findings Add 8 regression tests under TestToolOutputSynopsis, one per finding in @willem-bd's review of PR #3377: - test_review_5_log_lines_are_not_misclassified_as_yaml Pins the YAML detector to refuse 'LEVEL: message' log lines. - test_review_6_json_paths_are_emitted_without_byte_offset Pins the removal of byte/line hint from JSON path descriptions. - test_review_7_scalar_examples_respects_depth_cap Pins that 500-deep nested JSON does not raise. - test_review_8_csv_first_row_quoted_cells_round_trip Pins the new key=value list format for CSV first-row rendering and asserts that quoted cells with embedded delimiters survive. - test_review_9_tsv_detector_rejects_tab_indented_bash Pins that tab-indented bash output is not classified as TSV. - test_review_10_preview_includes_raw_head_and_tail_sample Pins the restored inline 'Raw sample (head + tail)' section. - test_review_11_short_text_does_not_duplicate_excerpts Pins that closer is suppressed for inputs shorter than 2 * _TEXT_EXCERPT_CHARS. - test_review_12_preview_head_tail_chars_are_operational Pins that head_chars / tail_chars are wired into the rendered preview and not silently dropped. Also removes the now-stale 'byte offsets are approximate anchors' sentence from render_tool_output_preview's Access block; the synopsis no longer emits byte/line hints, so the guidance to 'start near the line hints' was misleading. * fix(synopsis): resolve lint errors on tool output budget tests Local 'make lint' on feat/tool-output-synopsis-preview (after fast-forward to current main) failed with three errors in tests added by PR #3377: - E501: 307-char bash_out literal in test_review_9_tsv_detector_rejects_tab_indented_bash - E741: ambiguous single-letter 'l' in test_review_11_short_text_does_not_duplicate_excerpts - E741: same ambiguous 'l' on the closing assert Replace the long literal with a join of per-row entries, rename the loop variable from 'l' to 'ln', and run ruff format on the two touched files to absorb the formatting drift introduced by the merge with main. Verification: - make lint -> All checks passed; 643 files already formatted - pytest tests/test_tool_output_budget_middleware.py -> 110 passed * fix: address willem-bd review findings (code/csv misclassification, text duplication, line snapping, dead constant, xml hardening, depth consistency) - _CODE_HINTS: require stronger signals for use/fn (trailing ; or parenthesised) - _try_table: apply _TABLE_MIN_DATA_ROWS gate to CSV too (not just TSV) - config.example.yaml: correct misleading comment about preview_head/tail_chars - _summarize_text: skip opener/closer excerpts when raw sample will be appended - _build_raw_sample: snap to line boundaries for clean truncation - Remove dead constant _TABLE_FIRST_ROW_CHARS - Prefer defusedxml for XML parsing (billion-laughs protection), fallback to stdlib - Replace _json_shape magic number 2 with named _JSON_SHAPE_MAX_DEPTH constant - Update tests to match new CSV gate (>=5 rows) and line-snapped sample counts * style: ruff format fix for tool_output_synopsis.py and test_tool_output_budget_middleware.py * fix(tool-output): address 4 review comments - DoS hardening + size cap 1. XML entity-expansion DoS: skip _try_xml when defusedxml is not available (SafeET is None), falling through to text + raw sample. (cid=3587721336) 2. YAML alias-bomb DoS: refuse to parse YAML content > 500 KB. (cid=3587721340) 3. Unbounded content parse: add _MAX_SYNOPSIS_INPUT_BYTES=5MB cap; oversized output falls back to raw head/tail sample instead of full parse. (cid=3587721346) 4. Scalar examples surface mid-document values: add docstring note that the synopsis is a structural summary, not a confidentiality filter.

fix(agents): refuse empty SOUL.md updates in update_agent (#4219)
* fix(agents): refuse empty SOUL.md updates in update_agent setup_agent already rejects empty/whitespace soul (#3553). update_agent is the sibling write path and previously reported success while wiping a working SOUL.md. Mirror the same guard before staging. * fix(agents): guide the retry in the empty-SOUL update rejection Append "Omit the soul field if you do not want to change it." to the empty-soul error so the model self-corrects in one step instead of retrying with another null-like value, matching the "No fields provided" sibling message's helpfulness. Both regression tests assert the guidance. |

fix(helm): default sandbox Services to ClusterIP (#3929) (#4190)
* fix(helm): default sandbox Services to ClusterIP (#3929) The K8s sandbox provisioner supports both NodePort and ClusterIP via SANDBOX_SERVICE_TYPE (added in #4016), but the Helm chart never set it, so real-cluster installs inherited the NodePort default. That bound the code-execution sandbox on every node's interfaces - including externally reachable ones on GKE/EKS/AKS - and pinned every sandbox URL to one node IP (SPOF on node reboot/drain/ephemeral-IP). Default the chart to ClusterIP: the provisioner returns a cluster-DNS URL (http://sandbox-<id>-svc.<ns>.svc.cluster.local:8080) so the gateway-> sandbox hop stays inside the cluster network - no node IP, no 30xxx port, no external exposure. The chart always runs the gateway in-cluster, so ClusterIP is always correct there. NodePort remains an opt-in (provisioner.sandboxServiceType: NodePort + nodeHost) for the Docker-Compose/hybrid path where the gateway is not in K8s and cannot resolve .svc.cluster.local; the provisioner code default stays NodePort for that path. - values.yaml: add provisioner.sandboxServiceType ("ClusterIP") - provisioner-deployment.yaml: emit SANDBOX_SERVICE_TYPE; gate the NODE_HOST block on NodePort mode (default "ClusterIP" for upgrade safety) - NOTES.txt + README.md: document ClusterIP default + NodePort opt-in No change to docker/provisioner/app.py (already mode-aware since #4016) or RBAC (services verbs already cover ClusterIP). * test(helm): assert sandbox Service-type gating + CHANGELOG the default flip (#3929) Address review on #4190: - Add scripts/check_chart_sandbox_service.sh: renders the chart for the default (ClusterIP, no NODE_HOST), the NodePort opt-in (both emitted), and NodePort+nodeHost (literal value, not downward API). Locks in the #3929 gating so a regression (e.g. re-adding an unconditional NODE_HOST, or dropping the `default "ClusterIP"` upgrade-safety fallback) fails CI. Wired into .github/workflows/chart.yaml validate-chart job. (#2) - CHANGELOG [Unreleased] -> Changed: note the NodePort->ClusterIP default flip on upgrade + the `sandboxServiceType: NodePort` opt-back-in. (#4) No chart template changes (the gating itself landed in the first commit). --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(frontend): strip <memory> tags in Streamdown to avoid React console error (#4209)
* fix(frontend): use code-aware stripLeakedSystemTags for all internal marker tags Replace the ad-hoc /<\/?memory>/g in ClipboardSafeStreamdown with a dedicated stripLeakedSystemTags() function in preprocess.ts that: - Covers all INTERNAL_MARKER_TAGS (<memory>, <system-reminder>, <current_date>, <uploaded_files>, <slash_skill_activation>) instead of only <memory> - Is code-aware: skips fenced code blocks (```) and indented code blocks (4-space indent), so user-written meta-discussions about the memory system are not silently stripped - Handles opening tags, closing tags, self-closing tags, and tags with attributes - Adds 15 unit tests covering all the above cases * fix(frontend): use marker-aware fence tracking in stripLeakedSystemTags The boolean insideFence toggle incorrectly closes a fence on any line matching 3+ backticks or tildes, regardless of the actual delimiter. This causes tags inside a tilde-fenced block containing a backtick sub-fence, or a 4-backtick block containing a 3-backtick sub-fence, to be silently stripped. Track the opening fence marker (character and run length) so that only a matching marker with at least the same length closes the fence. Adds 4 new test cases: - Tilde fence with inner backtick fence - 4-backtick fence with inner 3-backtick fence - Shorter tilde closing inside longer tilde fence - Tags stripped after real closing fence * fix(frontend): fix TypeScript strict errors in fence marker tracking - Use non-null assertion (!) on fenceMatch[1] (guaranteed by regex) - Use charAt(0) instead of [0] to avoid string | undefined type |

feat(memory): LLM-assigned per-fact expected_valid_days and staleFactsToExtend (#4143)
Re-ports this feature onto the pluggable-memory backend introduced in #4122 (the original #4143 was force-pushed clean by accident and auto-closed). The #4122 refactor moved the staleness logic into the self-contained DeerMem backend (backends/deermem/deermem/core/) and reverted it to the pre-feature global-threshold version, so the per-fact lifetime work is re-applied here against the new module layout + DI (MemoryUpdater is now (config, storage, llm)-injected; config lives on DeerMemConfig, not host MemoryConfig). **expected_valid_days (creation)** The LLM assigns a per-fact review window when storing each new fact. The prompt exposes five tiers (<=14 d transient -> >365 d very stable). The value is capped at write time by staleness_age_days x staleness_max_lifetime_multiplier (default 20.0 -> 1800 d ~= 5 years; range 1.0-100.0) so the model cannot set an initial lifetime so long the fact is never re-evaluated. The default 20.0 makes the "> 365 d very stable" tier achievable out of the box (3.0 silently clamped it to 270 d). **staleFactsToExtend (review)** During staleness review the LLM can emit extension entries for kept facts whose window seems miscalibrated. new_evd = min(days_since_created + extend_by_days, staleness_max_extension_days). Extensions use an absolute ceiling (default 3650 d ~= 10 years; range 90-36500) rather than the creation multiplier - they are deliberate review decisions that must be able to advance the window beyond the initial cap, but the absolute bound prevents timedelta overflow (a model-supplied extend_by_days of 10**9 previously crashed every later candidate-selection pass with OverflowError) and LLM misfire. **Invariant correctness** - Read-time cap removed from _effective_fact_staleness_age; cap is write-time only so extensions actually advance the review window. - proposed_remove_ids hoisted out of the removals sub-block and used to exclude from extension, so a cap-surviving proposed-removal fact is never extended. - extend_by coerced to int before the > 0 guard (a fractional 0.9 would pass the float check then int() to 0, silently writing a zero-delta extension). - days_since uses total_seconds() // 86400 (not .days truncation). - staleness-section html.escape uses quote=False to match the prompt.py convention; only <, >, & break element-text structure. **Tests** test_memory_staleness_review.py was module-level skipped by #4122 ("full unit-test migration is a follow-up"). This PR performs that migration: DI construction via (DeerMemConfig, _FakeStorage), _build_staleness_section back to the (candidates, config) signature, plus new coverage for per-fact selection, EXTEND with the absolute cap, the overflow next-cycle regression, the proposed-removal-not-extendable case, fractional extend_by skipping, and the creation-time cap. 67 tests, all green. |

fix(memory): treat explicit null backend_config values as omitted in DeerMemConfig (#4217)
config.example.yaml ships backend_config.model: as a bare key whose children
are all comments, which YAML parses to None (make config-upgrade then writes
an explicit model: null). DeerMemConfig.model is a non-Optional field with a
default, so from_backend_config(**{"model": None}) raised a ValidationError
and every run failed with "Input should be a valid dictionary or instance of
DeerMemModelConfig". Drop None entries in from_backend_config so YAML null /
empty keys fall back to field defaults, matching the documented "empty =
host default LLM" semantics. Upstream bug (#4122 schema); regression-pinned
in test_deermem_self_contained.py.

fix(tracing): attach Langfuse trace metadata to the goal evaluator (#4202)
The goal evaluator (runtime/goal.py) runs from runtime/runs/worker.py after
the main graph run has already completed, so there is no graph root for it
to inherit tracing from. create_goal_evaluator_model was built with
attach_tracing=False, and evaluate_goal_completion invoked the model with a
bare config={"run_name": "goal_evaluator"} — no tracing callbacks, no
Langfuse session/user attribution. Every goal-evaluator LLM call went
untraced.
Same class of gap fixed by #2944 for the main agent graph and by #3902 for
memory_agent/suggest_agent: a standalone call site that invokes a model
directly instead of through a traced graph root must attach its own tracing
callbacks and inject Langfuse trace-attribute metadata itself.
- create_goal_evaluator_model: attach_tracing=False -> True, matching the
other standalone non-graph callers (oneshot_llm.run_oneshot_llm,
MemoryUpdater).
- evaluate_goal_completion: accept optional thread_id/user_id/
deerflow_trace_id and inject Langfuse trace metadata onto the ainvoke
config via the shared inject_langfuse_metadata() helper, mirroring
oneshot_llm.py's pattern.
- worker.py: thread user_id (resolve_runtime_user_id(runtime)) and
deerflow_trace_id through _prepare_goal_continuation_input into
evaluate_goal_completion so the evaluator's trace groups under the
triggering run's thread/session.
Updates the existing test that pinned attach_tracing=False as expected
behavior, and adds a regression test asserting the ainvoke config carries
Langfuse trace metadata when enabled.

fix(tui): stop empty-id assistant deltas from merging across turns (#4201)
_apply_assistant_delta matched AssistantDelta.id anywhere in the transcript, which is correct for a genuine per-message id but not for an empty one. runtime._as_str() coerces a missing/None chunk id to "", and that value is shared by every id-less chunk from every turn, not just the current one. Once one assistant row had id="", every later, unrelated AssistantDelta that also carried id="" (e.g. from a provider that never stamps per-chunk ids) matched that same stale row instead of starting a fresh one, silently folding a second turn's answer backward into the first turn's bubble. Route empty-id deltas to a dedicated path that tracks the current turn's row by position (streaming_anonymous_row_index, reset on RunStarted/ RunEnded/ClearRows) instead of by id, mirroring the existing empty-id guards in _apply_tool_started/_apply_tool_result but adapted for assistant text: unlike a tool call, an id-less assistant delta still needs to be displayed, so it starts a new row rather than being dropped. Multiple id-less chunks legitimately arrive within one turn (per-token streaming), so they keep coalescing into that row -- but only while it is still the transcript tail; once a tool card is appended after it (the same way a genuine id naturally changes across a tool round-trip), the next empty-id delta starts fresh instead of reaching backward past the tool card. Add regression coverage for the cross-turn merge, same-turn coalescing, the tool-call-interleaved edge case, and non-interference with the existing id-keyed path. |

* fix(mcp): offload blocking filesystem IO in MCP config update update_mcp_configuration resolved the extensions config path, probed its existence, read the raw JSON, wrote the merged config, and reloaded it — all blocking filesystem IO on the event loop (PUT /api/mcp/config). The whole read-modify-write after the async admin check has no interleaved awaits, so it moves into one _apply_mcp_config_update helper dispatched via asyncio.to_thread; the masked response is built on the loop. The secret-preserving merge, error codes, and the stdio command allowlist are unchanged. Found via `make detect-blocking-io`. Same class as #3457 / #3529 / #3551.

fix(gateway): keep create_thread idempotent when the insert loses a race (#3800)
* fix(gateway): keep create_thread idempotent when the insert loses a race The /api/threads create endpoint checks for an existing row and then inserts, but the two steps are not atomic. When two requests create the same thread_id concurrently, one commits first and the other's INSERT fails on the duplicate primary key. The SQL-backed thread store raises, the handler catches it as a generic failure, and the loser gets a 500 — even though the docstring promises the call is idempotent. Re-read the row after a failed insert: if it is now present (the competing request won), return it instead of surfacing the conflict. A genuine write failure where the row is still absent keeps the 500. Covered by a regression test that simulates the lost race and asserts the endpoint returns the existing thread rather than erroring. Signed-off-by: Yufeng He <40085740+he-yufeng@users.noreply.github.com> * fix(gateway): scope create_thread race recovery and mirror owner reconciliation Address review on #3800: - Scope the insert-race recovery to sqlalchemy IntegrityError instead of a broad `except Exception`, so a non-race failure that coincides with an existing row is no longer silently returned as a 200. Any other error logs and surfaces as a 500. (The memory store overwrites on duplicate rather than raising, so it never reaches this path.) - Route both the fast path and the recovery path through a shared `_resolve_existing_thread` helper so the recovery performs the same trusted- owner reconciliation (claiming a legacy unscoped `user_id=None` row) the fast path does. Thread ownership no longer diverges based on which path resolved the record. Add regression tests for both: the recovery claims an unscoped row for a trusted owner, and a non-IntegrityError failure surfaces as a 500. --------- Signed-off-by: Yufeng He <40085740+he-yufeng@users.noreply.github.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(memory): flush memory queue on graceful shutdown to prevent loss (#4181)
* fix(memory): bounded shutdown flush via MemoryManager.shutdown_flush
Re-applies the memory-queue shutdown drain on top of the pluggable
MemoryManager abstraction (#4122): the old top-level MemoryUpdateQueue
singleton is gone, so the drain is now a backend contract instead of
host code reaching into the queue.
- MemoryManager ABC: shutdown_flush(timeout) -> bool. Every backend
implements a bounded graceful-shutdown drain.
- DeerMem: queue.flush_sync (daemon-thread + Event.wait hard timeout
for the uninterruptible sync LLM call; joins an in-flight worker
first so contexts a debounce Timer already pulled out are not lost on
exit; skips inter-item sleep on the drain path; per-item
succeeded/failed count), exposed via shutdown_flush.
- noop: shutdown_flush is a clean no-op success.
- Gateway lifespan: call get_memory_manager().shutdown_flush(timeout)
after channels/scheduler stop, via asyncio.to_thread, try/except
bounded. No host-level pending/processing guard -- the backend
short-circuits on an idle buffer, so the host cannot "forget" the
in-flight case (structurally eliminates the guard race flagged on the
prior revision).
- shutdown_flush_timeout_seconds added to the shared MemoryConfig
(host-owned lifecycle budget, default 30, 1-300) + exposed on
MemoryConfigResponse and the embedded client; config_version 25 -> 26.
Tests: queue flush_sync (7), lifespan drain incl. False-branch caplog
assertion + disabled gate (3), ABC contract noop/deermem (3).
* fix(chart): gateway grace period so memory drain is not SIGKILLed
K8s defaults terminationGracePeriodSeconds to 30s, shorter than the
Gateway's graceful-shutdown work (channel stop ~5s + memory queue drain
default 30s). Without an explicit grace period, K8s SIGKILLs the memory
drain mid-flight and silently re-introduces the loss shutdown_flush is
fixing (flagged on the prior revision).
- gateway pod: terminationGracePeriodSeconds (default 45, configurable).
- gateway container: preStop sleep (default 5, 0 disables) so the
Service/ingress deregisters the pod before SIGTERM begins the drain.
- values.yaml + README: both configurable; README documents that the
grace period must track memory.shutdown_flush_timeout_seconds.
* docs(memory): document shutdown_flush_timeout_seconds + lifespan drain
Add the host-shared field to the memory config list and Config Schema
summary in backend/AGENTS.md, noting the lifespan drain and the K8s
grace-period relationship.
* fix(chart): bump embedded config_version to 26
The chart's embedded `config:` block (values.yaml + README example) still
had config_version: 25 after commit

fix(goal): stop continuation_count double-bump in thread_changed_before_continuation stand-down (#4199)
_prepare_goal_continuation_input calls the same _persist closure twice with the identical next_count in one evaluation cycle: once to commit the real continuation, and again to record a thread_changed_before_continuation stand-down if a race is detected right after that commit. The second call re-passed continuation_count=next_count, so #4088's defensive max(continuation_count, current_count + 1) guard saw the first call's own write as a "current_count" bump and added another +1 on top of it - silently consuming 2 units of the continuation budget for a cycle that delivered zero actual continuations. #4088's guard is correct for the independent-concurrent-continuations race it targets; this is a separate call site incorrectly re-triggering that same guard against itself. The second _persist call no longer passes continuation_count, matching every other stand-down call site in this function - the count was already correctly committed by the first call. Adds a regression test mirroring the existing thread_changed_after_evaluation race test's checkpointer-wrapper technique, since this sibling branch had zero prior coverage. |

fix(skills): reuse the resolved app config in the no-arg skills prompt section (#4160)
get_skills_prompt_section() without app_config resolved get_app_config() only to read container_path, then let the enabled-skills load fall back to the warm cache. On a cold start the cache is empty and the first call returns an empty skills list while the synchronously-loaded disabled section is populated, so manually assembled agents (create_deerflow_agent style integrations) got a prompt with no enabled skills. Rebind the resolved config so the storage and enabled-skills loads below use it too; when no config is resolvable the cache-only fallback is unchanged. Adds a cold-cache regression test.

fix(channels): dedupe GitHub webhook redeliveries (#4104)
* fix(channels): dedupe GitHub webhook redeliveries The inbound dedupe added for the IM channels in #3584 keys ChannelManager._is_duplicate_inbound on a top-level metadata["message_id"] plus a workspace id. The GitHub channel added later in #3754 never populated either: the X-GitHub-Delivery GUID was buried in metadata["github"]["delivery_id"] and no workspace id was set, so every GitHub delivery produced a None dedupe key and was never deduped. GitHub reuses the same X-GitHub-Delivery GUID when a delivery is retried after a timeout or replayed via the repo/App "Redeliver" button, so a redelivery re-ran the agent with real side effects (e.g. a duplicate PR comment) while the other channels absorbed an identical redelivery. fanout_event now stamps the dedupe identity the manager already consumes: - workspace_id = repo (globally unique, always present; mirrors Telegram/WeChat keying the workspace on the chat id) - metadata["message_id"] = f"{delivery_id}:{agent.name}" A single delivery fans out to N agents, so the id is scoped to (delivery, agent): an identical redelivery reproduces the same pairs (deduped) while two agents matching the same delivery keep distinct ids and both still fire. When the delivery header is absent the id is left None, so the manager fails open exactly as before. Tests: dispatcher-level coverage that the identity is stamped, stable across redelivery, and distinct per agent/delivery; a ChannelManager regression that an identical GitHub redelivery dispatches once while a new delivery and a second agent on the same delivery still fire. * fix(channels): scope GitHub dedupe id by owning user _inbound_dedupe_key indexes on (channel, workspace_id, chat_id, message_id). For GitHub, workspace_id and chat_id are both the repo, so the owning user was never represented anywhere in the key - fanout_event stamped the id as f"{delivery_id}:{agent.name}". Two different users each binding an agent of the same name (e.g. "reviewer") to the same repo+event therefore produced an identical dedupe id for both fan-out messages. ChannelManager._is_duplicate_inbound treated the second as a replay of the first and silently dropped it, even though GitHub delivered the webhook once and both users' agents legitimately matched. Fold match.user_id into the id: f"{delivery_id}:{match.user_id}:{agent.name}". Genuine redeliveries (same user, same agent, same delivery) still produce the same id and are deduped; two agents - same-named or not, same user or not - on one delivery now always keep distinct ids. Tests: new cross-user regression pins that two users' same-named agents both dispatch instead of the second being deduped against the first; the existing per-(delivery, agent) test and the literal id assertion in test_delivery_id_populates_inbound_dedupe_identity are updated for the new id shape. * fix(channels): point cross-user dedupe comment at its regression test Replace the inline reviewer-handle attribution with a pointer to test_dedupe_identity_distinguishes_same_agent_name_across_users, which ages better than a person's name in committed code. |

feat(memory): pluggable memory abstraction with self-contained DeerMem backend (#4122)
* feat(memory): pluggable + self-contained memory system (MemoryManager plan phases 1 & 2)
Phase 1 — Pluggable (steps 0-10):
- ABC MemoryManager (9 methods) + singleton factory + drop-in backend discovery
- DeerMem default backend with core/ (storage/queue/updater/prompt/message_processing)
- NoopMemoryManager backend (proves pluggability)
- All call sites (middleware/hook/prompt/gateway/client/app) routed through manager
- hasattr capability probing for DeerMem-internal methods (no hard imports)
- MemoryConfig gains manager_class field; shared vs DeerMem-private annotated
Phase 2 — Self-contained DeerMem (steps 11-18):
- backend_config passthrough + DeerMemConfig (all DeerMem-private fields moved off MemoryConfig)
- DI: DeerMem owns storage/queue/updater/llm as instance attributes (no global singletons)
- Storage independence: core/paths.py with own root (~/.deermem or ),
factory auto-injects deer-flow's runtime_home() as absolute base_dir (zero-config)
- LLM independence: core/llm.py via langchain init_chat_model (no create_chat_model)
- Trace independence: optional tracing_callback replaces inject_langfuse_metadata/request_trace_context
- Message processing independence: hide_from_ui default-skip + optional should_keep_hidden_message hook
- Internal imports → relative (only deer_mem.py ABC import is host-relative)
- Carrier (deer_mem.py adapter) / portable (deermem/ config+core) split
- New tests: test_deermem_self_contained + test_memory_manager_pluggable; all memory tests migrated
- Other-agent demo: samples/other_agent_demo/ + automated portability test
- config.example.yaml memory section updated to phase-2 schema
* feat(memory): port consolidation + staleness fix into self-contained DeerMem; phase-2 host hooks
Port upstream #3996 (memory consolidation) and #3993 (staleness KeyError fix)
from origin/MemoryManager into the pluggable, self-contained DeerMem structure
(backends/deermem/deermem/), adapted to the DI MemoryUpdater (config injected,
not get_memory_config globals):
- DeerMemConfig: add consolidation_enabled (opt-in, default false) /
consolidation_min_facts / consolidation_max_groups_per_cycle /
consolidation_max_sources
- prompt.py: factsToConsolidate JSON field + {consolidation_section} placeholder
+ CONSOLIDATION_PROMPT constant
- updater.py: _coerce_source_confidence / _select_consolidation_candidates /
_build_consolidation_section module helpers (matching the existing
_select_stale_candidates style); consolidation normalization in
_normalize_memory_update_data; consolidation apply in _apply_updates (after
max_facts trim, with apply-time guardrails mirroring staleness); staleness
KeyError fix (f["id"] -> f.get("id") is not None) applied to both the
staleness guardrail and the consolidation allowed_source_ids comprehension
- config.example.yaml: consolidation section under memory.backend_config
- tests/test_memory_consolidation.py: 40 DI-adapted tests (running, not skipped)
incl. the staleness KeyError regression
Also includes in-flight phase-2 host-integration work: storage_path semantics
(any absolute/relative value = root dir) and host-default tracing_callback /
should_keep_hidden_message hooks injected into backend_config by the factory.

* feat(memory): add noop backend template and backends guide
- backends/noop/: complete drop-in template (config.py with zero deer-flow
imports, noop_manager.py with a 6-step new-backend walkthrough in its
docstring, commented optional fact-CRUD capabilities).
- backends/README.md: which files to touch when adding/swapping a backend,
the 5-item backend contract, and common pitfalls.
- manager.py: generalize backend examples in comments (drop mem0-specific
references).
Co-Authored-By: Claude <noreply@anthropic.com>
* fix(frontend): guard formatTimeAgo against invalid timestamps
Return a neutral placeholder when the input date is invalid (e.g. an empty lastUpdated from a backend with no memories) instead of throwing 'Invalid time value' from date-fns.
Co-Authored-By: Claude <noreply@anthropic.com>
* feat(memory): wire tool-driven memory mode through the MemoryManager ABC
tools.py (memory_search/add/update/delete) now calls get_memory_manager()
instead of the removed host memory module, so tool mode (memory.mode: tool)
works for any backend. DeerMem.search is implemented (case-insensitive
substring match, ranked by confidence) as a stand-in for the planned
semantic retrieval; noop.search returns [] (unchanged). Fact-CRUD tools
use getattr+callable probing -- backends lacking those ops (noop) get a
clear JSON error instead of crashing.
Tests: test_memory_tools rewired to mock the manager (handler tests) +
TestModeGating retained; test_memory_search now covers DeerMem.search;
pluggable stubs test updated (search no longer a stub).

* fix: resolve lint errors (import sorting, type annotation quotes, E402 in skipped tests)
* docs: restore explanatory comments in config.example.yaml memory section
* fix(security): port html-escape memory facts fix (#4097) to vendored DeerMem prompt.py
* fix(memory): address review + port dropped upstream memory fixes
Review blockers (vendored DeerMem):
- #4044 restore _escape_memory_for_prompt (current_memory blob in
MEMORY_UPDATE_PROMPT) - prevents </current_memory> breakout
- #4028 html.escape staleness-section cat/content in _build_staleness_section
- #4119 add _escape_summary for injection-path summaries (Work/Personal/
Current Focus/Recent/Earlier/Background)
- default-model silent no-op: factory injects host default chat model via a
new host_llm slot (create_chat_model(name=None)); DeerMem prefers host_llm
over build_llm(model). Zero-config extraction works out of the box again
- MemoryConfigResponse: fix stale docstring (backend-agnostic shape; DeerMem
knobs live under backend_config, not top-level - restoring flat would
re-couple the API to DeerMem). Frontend audited: does not read /memory/config
- _host_default_tracing_callback: restore langfuse assistant_id/environment
- search: push category onto the ABC signature; DeerMem filters BEFORE the
top_k slice (was filtered client-side after slicing -> starved results)
- _do_update_memory_sync: split into wrapper+impl; bind trace_id into the
request-trace ContextVar on the Timer/executor worker via a new
trace_context_manager host hook (None trace_id left unbound - no fabrication)
- client.py fact-CRUD now passes user_id (was writing to the global bucket
while get_memory reads per-user)
- _resolve_manager_class: fail-fast (raise ValueError) on an unresolved
explicit manager_class instead of silently falling back to DeerMem (memory is
persistent state - a wrong store is a silent data-integrity footgun)
Upstream memory fixes dropped by the host->vendored rename conflict, re-ported
to backends/deermem/deermem/core/ (+ deer_mem.py):
- #4073 queue busy-timer-spin -> _reprocess_pending flag (core/queue.py)
- #4074 null source.confidence in staleness -> _coerce_source_confidence
(core/updater.py: _build_staleness_section + _apply_updates stale sort)
- #4075 factsToRemove is optional (drop from _REQUIRED_MEMORY_UPDATE_TOP_LEVEL_KEYS)
- #4076 null confidence in search ranking -> _coerce_source_confidence
(deer_mem.py DeerMem.search)
host_llm + trace_context_manager are host-injected via backend_config (factory
in manager.py), keeping backends/deermem/ at exactly one `from deerflow` line
(the ABC contract) - portability test preserved.

* fix: resolve lint errors (F541 f-string without placeholders, E501 line too long)
* fix(memory): restore hide_from_ui clarification preservation, expose mode
Two memory-system fixes (F541/E501 lint was already fixed on this branch):
- filter_messages_for_memory: restore default preservation of well-formed
human_input_response clarification answers (v2 regression). The
self-containment refactor made the bare function skip ALL hide_from_ui when
no hook was passed, but upstream preserves well-formed clarification
responses by default (test_hide_from_ui_human_input_response_is_preserved).
Inline a host-agnostic _is_human_clarification_response mirror of
read_human_input_response as the default keep-decision; the host-injected
should_keep_hidden_message hook still overrides (production path unchanged).
Portable package stays zero `from deerflow`.
- /memory/config: expose `mode` (middleware|tool) in MemoryConfigResponse +
the config/status endpoints + client.get_memory_config. mode is a host-
shared, behavior-determining field missing from the response projection.
Sync tests (mock .mode; e2e assert mode present).
- Align manager_class field docstring with fail-fast behavior.
Tests: filter/self-contained/portability (35) + memory-config (4) pass;
ruff clean.
Co-Authored-By: Claude <noreply@anthropic.com>
* fix(memory): resolve ruff format failures in memory module + tests
`make lint` runs `ruff format --check` in addition to `ruff check`; 8 memory
files had pending format changes -- 7 pre-existing (deer_mem, updater, tools,
test_memory_queue/router/search/tools) + message_processing from the
hide_from_ui fix. Apply `ruff format`: whitespace/wrapping only, no logic
change. 109 memory tests pass; ruff check + format --check both clean.

Phase 0 of the RFC in #4063: scaffolding only, zero behavior change. New deerflow/authz/ package (sibling to deerflow/guardrails/): - AuthorizationProvider Protocol: authorize() + aauthorize() + filter_resources() - Principal/AuthzRequest/AuthzDecision/AuthzReason dataclasses - GuardrailAuthorizationAdapter: bridges AuthorizationProvider → GuardrailProvider so existing GuardrailMiddleware can enforce authz decisions without a new middleware New authorization config section (default enabled: false): - AuthorizationConfig wired into AppConfig alongside guardrails - Singleton load/reset mirrors GuardrailsConfig pattern - config.example.yaml documents the RBAC provider schema 29 tests covering protocol conformance, dataclass construction, adapter request/decision mapping, and config singleton behavior. Per RFC #4063 Phase 0 (foundations). Layer 1/2 wiring and Principal builder in services.py deferred to Phase 1. |

ci(helm): publish chart to charts/ namespace prefix on GHCR (#4175)
* ci(helm): publish chart to charts/ namespace prefix on GHCR
Push the Helm chart to ghcr.io/<owner>/charts/deer-flow (via a `charts/`
prefix on the `helm push` target) instead of the bare `deer-flow`
package. This namespaces the chart apart from the image packages
(deer-flow-{backend,frontend,provisioner}) without renaming the chart:
Chart.yaml `name` stays `deer-flow`, so dir = chart name = in-cluster
resource/selector names, and no `nameOverride` hack is needed.
The chart is new in 2.1.0 (chart infra landed in #3987, after v2.0.0),
so 2.1.0 is the first chart release. Early nightly builds remain at the
legacy non-prefixed ghcr.io/<owner>/deer-flow.
Also refresh chart release docs:
- Replace the removed scripts/build-and-push.sh in the chart README with
raw `docker build`/`push` commands (contexts/args match container.yaml).
- Point NOTES.txt's empty-registry warning at the README section instead
of the removed script.
- Retarget RELEASING.md version examples from 2.2.0 to 2.1.0.
- Bump the chart README's helm prerequisite to 3+.
* docs(helm): require helm 3.8+ and note legacy chart package cleanup
Address PR #4175 review:
- bump documented minimum to helm 3.8 (OCI registry support stabilized
there; earlier 3.x needs HELM_EXPERIMENTAL_OCI=1)
- add a post-release note to delete/revoke the legacy bare
ghcr.io/<owner>/deer-flow chart package after 2.1.0

fix(agents): require config.yaml in update_agent's legacy-agent guard (#4166)
update_agent (the harness tool) and PUT /api/agents/{name} (the same
operation over HTTP) share an identical guard meant to block updates to
an agent that only exists in the legacy shared layout. The guard checked
bare directory existence:
if not agent_dir.exists() and paths.agent_dir(name).exists():
When memory is enabled, the first time a user chats with a legacy shared
agent, the memory writer creates a per-user directory containing only
memory.json (no config.yaml). agent_dir.exists() is then true, so the
guard never fires: the tool falls through to load_agent_config, which
resolves through to the legacy shared config via the already-hardened
resolve_agent_dir, and silently writes a brand-new config.yaml/SOUL.md
into the memory-only directory. That forks the agent for just this user;
every other user keeps reading the original shared config forever, with
no error or warning.
resolve_agent_dir itself was already hardened against exactly this
failure mode: it requires config.yaml to exist, not just the directory.
Mirror that condition at both call sites here.

fix(security): html-escape the conversation block in MEMORY_UPDATE_PROMPT (#4162)
format_conversation_for_update embeds raw user turns into the <conversation> slot of MEMORY_UPDATE_PROMPT. This is the most attacker-influenced input in the prompt, and it was unescaped: a message containing "</conversation><current_memory>..." closes the conversation block and forges a <current_memory> authority section for the extraction LLM, which can be steered into persisting an arbitrary high-confidence fact — and that fact is later injected into the lead-agent system prompt's <memory> block, which the prompt declares trusted. This is the last unguarded sibling of a rule the repo has established repeatedly. #4044/#4060 html-escaped the current_memory slot of this exact template; #4097 escaped the <memory> injection renderer. In updater.py the same .format() call escapes current_memory and leaves conversation raw. The memory updater sees raw text because InputSanitizationMiddleware only rewrites the ModelRequest and never mutates state, while MemoryMiddleware queues the raw state messages. Escape content with html.escape(quote=False), mirroring _escape_summary / _format_fact_line — after truncation so a trailing "..." cannot split an entity, on both human and assistant turns. Render-time only: no stored value is mutated, so the apply path is unaffected. The conversation function already strips <uploaded_files> here, so tag hygiene in this renderer is established. Scope is the memory updater. The summarizer's <new_messages> / <existing_summary> blocks are the same rule unguarded, but their output is quarantined as untrusted durable context rather than promoted to system authority; that hardening will be a separate change. |

fix(skills): recognize fully deleted public skill packages in review CI (#4169)
select_skill_packages() resolved every changed non-SKILL.md path to its owning package via an unconditional depth-3 fallback, then queued that path for review. When a PR deletes an entire public skill package (not just SKILL.md, but its scripts/assets/etc. too), the fallback still returned the package directory even though it no longer exists on disk post-deletion. The review CLI then reported a false structure.missing-skill-md blocker for a path that isn't there, failing CI on a routine, correct package removal. Skip a resolved package only when every changed file under it was a deletion and the package directory itself is gone from disk - i.e. the whole package was intentionally removed. A package left in a broken/partial state (e.g. SKILL.md deleted while sibling files remain) still resolves to an existing directory, so it is unaffected and continues to be queued and flagged. |

fix(agents): stop persisting base64 image data in checkpoint state (#4140)
* fix(agents): stop persisting base64 image data in checkpoint state (#4138) The viewed_images state field stored full base64-encoded image data, which was duplicated across every subsequent checkpoint (O(n * steps) growth). A single 1MB image viewed early in a conversation would be re-stored in every checkpoint for the rest of the session. Changes: - ViewedImageData: replace base64 field with lightweight metadata (mime_type, size, actual_path) - view_image_tool: store only metadata in state, no base64 encoding - ViewImageMiddleware: read image files from disk on-demand in before_model and encode base64 temporarily for the model call - Update all tests to use the new metadata-only format This is the first step of #4138. The base64 data is no longer in persistent state, but the injected HumanMessage (with base64 content) still appears in the checkpoint for the step where it was injected. Checkpoint retention policies and large tool result dedup are separate follow-up items. * fix(agents): address review feedback on #4140 - view_image_tool: remove stale 'convert to base64' comment, replace with 'validate contents'; drop redundant image_size reassignment and add a TOCTOU guard that rejects files changed between stat() and read(). - view_image_middleware: extract _read_image_as_data_url helper that re-checks size against the recorded value AND the absolute cap (_MAX_IMAGE_BYTES). Document the trust assumption for actual_path (server-set, not client-settable) in the helper docstring. - view_image_middleware: abefore_model now runs the blocking read+encode via asyncio.to_thread to avoid stalling the event loop on up to 20MB images. - tests: add coverage for OSError during read, file-changed-since-view (TOCTOU), and size-exceeds-cap branches. |

fix(channels): drop redundant GitHub review-comment webhook fan-out (#4131)
* fix(github): drop redundant pull_request_review_comment fan-out noise
GitHub fires one pull_request_review_comment webhook per inline comment
attached to a pull_request_review submission, in addition to the single
pull_request_review event for the review itself. A bot reviewer like
CodeRabbit commonly leaves 20-30 inline comments per review, flooding
the webhook with near-duplicate deliveries that carry nothing an agent
doesn't already have -- it fetches every inline comment itself via
`gh api` when it processes the parent pull_request_review event.
Filter these out in fanout_event() before the registry lookup / per-
agent loop, since the redundancy is a property of the event itself, not
of any specific agent binding. A companion comment is identified by
pull_request_review_id being set (it belongs to a review) and
in_reply_to_id being absent (it is not itself a reply within an

* fix(channels): scope review-comment suppression to bindings that also see the review
The redundant pull_request_review_comment filter suppressed every
companion comment unconditionally, before the registry lookup even ran.
That premise only holds for a binding that also subscribes to
pull_request_review on the same repo -- events are opt-in per binding,
so a binding registered for pull_request_review_comment alone never
receives the parent review event and the companion comments were its
only delivery of the review's inline content. Suppressing those too was
a silent, total loss for that binding, not noise reduction.
Move the check into the per-agent loop so it only suppresses a matched
binding's companion comment when that same binding also has an active
pull_request_review trigger on this repo, reusing the existing registry
lookup rather than re-walking bindings by hand. Bindings subscribed to
pull_request_review_comment alone now always fire, matching the
opt-in-per-binding contract documented in triggers.py.

fix(subagents): prohibit task tool in general-purpose system prompt (#4161)
* fix(subagents): prohibit task tool in general-purpose system prompt (#4159) The general-purpose subagent correctly lists `task` in disallowed_tools to prevent recursive nesting. However, the system prompt did not explicitly tell the LLM that `task` is unavailable. When the subagent sees the parent agent use `task`, it infers the tool is available and attempts to call it, triggering a LangGraph tool validation error. Add an explicit <tool_restrictions> block to the system prompt stating that `task` is NOT available and the subagent must NEVER attempt to call it. This prevents the LLM from attempting the call in the first place, rather than relying on runtime rejection. Add a regression test verifying the prompt contains the prohibition. * fix(security): register tool_restrictions in input sanitization denylist PR #4161 added <tool_restrictions> to general_purpose.py subagent prompt but did not register it in _BLOCKED_TAG_NAMES. The anti-drift test test_denylist_covers_framework_authority_blocks caught this: forging <tool_restrictions> in untrusted input could trick the model into believing it has (or lacks) tool restrictions it does not. Add 'tool_restrictions' to _BLOCKED_TAG_NAMES alongside the other subagent authority blocks (file_editing_workflow / guidelines / output_format / working_directory). |

fix(middleware): drop orphan ToolMessages so strict providers don't 400 (#4080)
* fix(middleware): drop orphan ToolMessages with no matching AIMessage tool_call The rebuild loop only skipped ToolMessages whose tool_call_id matched a known AIMessage tool_call (to be re-emitted after it). An orphan ToolMessage whose tool_call_id has no matching AIMessage tool_calls fell through and was kept, leaving a dangling tool result that strict providers reject. Drop orphan ToolMessages as well, logging at debug. * fix(dangling): demote orphan-drop logs, add tool_call_id=None test - Update module/class docstrings to mention orphan ToolMessage handling - Accumulate orphan drop_count and emit a single logger.warning instead of per-message logger.debug calls - Simplify early-return logic: return None only when no patching AND no orphans were dropped - Add test_tool_call_id_none_orphan_is_dropped — a ToolMessage with tool_call_id=None is always an orphan and must be dropped Closes #4080 Co-Authored-By: Claude <noreply@anthropic.com> * fix(test): use model_construct for None tool_call_id test to bypass pydantic validation ToolMessage content='ghost' tool_call_id=None fails pydantic validation at construction. Use model_construct to simulate a corrupt/edge-case payload without tripping the string-only guard.

fix(mcp): invalidate tools cache on config content + path, not just newer mtime (#4124)
* fix(mcp): invalidate tools cache on config content + path, not just newer mtime The MCP tools cache invalidated only on a strict extensions-config mtime `>` comparison and tracked no resolved config path, so `_is_cache_stale()` missed: - content changes with an unchanged mtime (same-second edits; object-store / network mounts that do not bump mtime); - content changes with a backward mtime (git checkout, cp -p / backup restore, tar / rsync preserving timestamps); - a resolved-path switch to a different config file with mtime <= the recorded value (structurally invisible — no path was tracked at all). On multi-worker (uvicorn/gunicorn) or stale-mtime deployments this leaves the LangGraph-embedded runtime and every non-writer worker serving stale MCP tools after `PUT /api/mcp/config`, breaking the module's documented promise that changes made through the Gateway API are reflected in the embedded runtime. Record the resolved config path and a `(mtime, size, sha256)` content signature at initialization and invalidate when the path OR the signature differs (`!=`), mirroring `config/app_config.py::get_app_config()` so the two runtime-editable config files share one content-based staleness signal. The per-call stat was already paid, and the small-file sha256 matches the cost app_config pays per request. The "config missing / not yet initialized" no-op behavior and the cache reset endpoint are preserved. Adds backend/tests/test_mcp_cache.py covering all three failure modes plus unchanged-file and forward-edit sanity cases. Also folds in an incidental backend/AGENTS.md doc-sync: the restart-required field list was missing `scheduler` and `run_ownership`, both present in reload_boundary.py::STARTUP_ONLY_FIELDS. * test(mcp): pin cache staleness contracts raised in review Two review observations on the content-signature cache fix, both raised as non-blocking design questions rather than bugs: - Whether relying on mtime+size alone (skipping the sha256) could ever be "optimized" back in, reopening the narrow same-second / identical-length swap gap the signature was built to close. - Whether the extensions config being deleted entirely after a successful init leaves the cache in a defined state, since current_signature flips to None and _is_cache_stale() returns False. Neither is a behavior change: both were already the intended contract, preserved verbatim from the pre-fix mtime-only code (which also returned False once the file could no longer be stat-ed). Record the reasoning inline and add regression tests that pin each contract so a future change cannot alter either silently: - test_same_mtime_same_size_swap_is_stale: a same-length server-name swap that leaves mtime AND size unchanged (the precise scenario from review, sharper than the existing same-mtime test, which also changes size) is still caught only because the sha256 is computed unconditionally. - test_config_deleted_after_init_is_not_stale: deleting the config file after init keeps the cache serving its last-known-good MCP tools instead of invalidating into an unconfigured state. Both new tests were confirmed to fail against a deliberately reintroduced version of the regression they guard (hash short-circuit / removed None-guard), then confirmed to pass against the real code. |

docs(api): document stateless /api/runs/stream endpoint (#4177)
* docs(api): document stateless /api/runs/stream endpoint
Record that clients can start a conversation without pre-creating a thread,
and that Gateway returns thread_id and run_id via the Content-Location header.

* docs(api): show on_run_created for stateless stream continuation
The Python SDK example now captures thread_id/run_id via on_run_created
before documenting the follow-up call with config.configurable.thread_id,
matching the TS/cURL examples and langgraph-sdk 0.3.x behavior.

fix(middleware): window LoopDetection tool-frequency counter so long runs don't false-trip (#4072)
* fix(loop-detection): decay per-tool frequency counter with a windowed deque The Layer 2 per-tool-type frequency guard in _track_and_check used a monotonic integer counter (freq[name] += 1) that never decayed or reset, so a long-running thread could trip the frequency warn/hard-stop even when calls were spread out over the whole run. Replace it with a deque of recent tool names trimmed to window_size, matching the windowed hash layer, and count occurrences within the window. Update _evict_if_needed and reset() to manage the new _tool_name_history storage. * address review: size Layer-2 freq window to the hard limit, not window_size The windowed freq_count is bounded by the deque length; reusing Layer-1's window_size (default 20) capped it below tool_freq_warn (30) / hard (50), making the Layer-2 guard dead code under the shipped default config. Size a dedicated _tool_freq_window = max(window_size, tool_freq_hard_limit, override hard limits) so a tight burst reaches the limit while spread-out calls still decay. Per @willem-bd review on #4072. Adds default-config regression tests: freq window >= hard limit, override coverage, and a tight-burst-with-distinct-args hard-stop under real defaults. Co-Authored-By: Claude <noreply@anthropic.com> * fix(#4072): docstrings describe windowed semantics; defaultdict+Counter for O(1) Addresses willem-bds three inline nits: 1. Docstrings for tool_freq_warn/tool_freq_hard_limit now explain the sliding-window semantics and reference _tool_freq_window sizing. 2. Hot-path deque() allocation avoided: _tool_name_history uses defaultdict(deque) instead of dict.setdefault(thread_id, deque()). 3. O(window) sum() scan replaced with mirrored collections.Counter (incremented on append, decremented on popleft) for O(1) freq_count. --------- Co-authored-by: Claude <noreply@anthropic.com> |

fix(DB): legacy backfill creates missing Index objects on existing tables (#4090)
* fix(DB): legacy backfill creates missing Index objects on existing tables _run_baseline_create_all_sync calls create_all(tables=..., checkfirst=True). SQLAlchemy's Table.create(checkfirst=True) skips the table AND all its Index objects when the table already exists, so an index added to the ORM model after the table was first provisioned (e.g. the partial unique index uq_channel_connection_active_identity on channel_connections) is never created, and stamping 0001_baseline skips alembic's own create_index call too. Fix: after create_all, explicitly create every Index on every baseline table with Index.create(checkfirst=True), which checks for the specific index independently of the table. Co-Authored-By: Claude <noreply@anthropic.com> * docs(bootstrap): note future-index backfill collision risk for revisions Add a short forward-looking block under the legacy index-level backfill (at backend/packages/harness/deerflow/persistence/bootstrap.py:308-322) pointing the next contributor at the same shape risk the module already documents for _baseline_TABLE_NAMES: if a future post-baseline revision adds an index to a baseline table via op.create_index(...) without checkfirst=True, the backfill above will already have pre-created it and the upgrade will collide with 'index already exists'. Mirror safe_add_column and use checkfirst=True (or a future safe_create_index helper) in such a revision. * fix(#4090): scope legacy backfill index loop to _BASELINE_INDEX_NAMES willem-bd identified that the index loop iterated table.indexes (current ORM models full set), which includes post-baseline indexes like uq_runs_thread_active from 0004. Creating these prematurely before their owning revisions dedup step raises IntegrityError on legacy DBs with duplicate active rows -- bricking bootstrap. Changes: - Add _BASELINE_INDEX_NAMES: frozenset of 23 indexes that 0001_baseline actually creates (mirrors _BASELINE_TABLE_NAMES pattern) - Guard index-creation loop with _BASELINE_INDEX_NAMES filter - Wrap each idx.create() in try/except for graceful duplicate-data handling (uq_channel_connection_active_identity has no owning revision dedup) - Fix misleading checkfirst=True comment for alembic op.create_index - Add guard test pinning _BASELINE_INDEX_NAMES against 0001 output - Add regression test with duplicate active runs (the exact crash case) - Add regression test with duplicate channel connections (graceful handling) * fix(tests): update legacy backfill fixtures to current schema - Seed runs and channel_connections using the actual 0001 baseline columns. - Preserve the duplicate-active-row conditions exercised by the regression tests. - Apply ruff formatting required by backend CI. --------- Co-authored-by: Claude <noreply@anthropic.com> |
