Keep this boundary aligned with the backend request schema; `messages` and `events` are not supported and must not be forwarded. - **SSE replay gaps** are handled in `core/api/api-client.ts`, which wraps both initial and joined run streams because the upstream SDK ignores unknown event names. An id-less backend `gap` control frame clears stale reconnect metadata, emits an internal `stream_replay_gap` custom event, reloads durable thread values, and rejoins after the server-provided retained tail, with up to five recovery rejoins after the original stream (six total stream calls on an all-gap exhaustion path). The wrapper remains a lazy async iterable because the SDK consumes it with `for await`. `core/threads/hooks.ts` clears optimistic/transient/subtask state, invalidates durable history caches, and shows the localized recovery warning; never let a gap fall through as a normal stream finish or cancel the still-running backend run. - **Streaming Markdown rendering** is owned by `core/streamdown`: Streamdown's `animated` / `isAnimating` API handles incremental word animation, while the shared `streamdownRenderingPlugins` config registers the named code-highlighting and Mermaid plugins required by Streamdown 2.5. Keep wrappers and derived configs wired to that shared object; do not reintroduce a rehype plugin that wraps every word, because reparsing a growing block remounts old words and replays their animation. +- Citation links in message and artifact Markdown must derive their `citation:` label from the full `ReactNode` children tree, since Streamdown may provide element or array children during streaming rather than a plain string. - **Environment validation** uses `@t3-oss/env-nextjs` with Zod schemas (`src/env.js`). Skip with `SKIP_ENV_VALIDATION=1` - **Subtask step history and runtime metadata** (`core/tasks/`) — the subtask card shows a subagent's full step timeline (#3779): its assistant reasoning turns interleaved with the tools it ran. `Subtask.steps[]` is accumulated live from `task_running` events (appended via `mergeSteps`, not overwritten) and backfilled on expand for historical runs by `fetchSubtaskSteps`, which pages the events endpoint scoped to one task (GET `/runs/{runId}/events?event_types=subagent.step&task_id=…&after_seq=…`) until a short page, so the run-wide limit can't truncate the timeline. `task_started` carries the effective `model_name`; `task_running` carries a cumulative usage snapshot after each completed LLM call. `core/tasks/lifecycle.ts` normalizes these additive events, and `computeNextSubtask` keeps the largest cumulative total so replayed or late SSE frames cannot double-count or roll the folded card backward. Terminal ToolMessage metadata (`subagent_model_name` / `subagent_token_usage`) restores the same values from normal history after reload; no per-card event fetch is needed. `core/tasks/steps.ts` is the pure step model: `messageToStep` (live), `eventsToSteps` (reload), `mergeSteps` (dedup by `message_index`), and `stepsForDisplay` (what the card renders — keeps tool steps + AI steps with text, drops the trailing final-answer AI step when completed since it's shown as `result`). `core/tasks/context.tsx`'s `useUpdateSubtask` applies updates against a `tasksRef` mirroring the latest state (not a closure snapshot), so a late-resolving `fetchSubtaskSteps` backfill merges into current state instead of clobbering SSE steps or sibling subtasks that arrived meanwhile. The owning `run_id` is carried onto history content messages in `buildVisibleHistoryMessages` so the card can resolve the events endpoint. diff --git a/frontend/src/components/workspace/citations/artifact-link.tsx b/frontend/src/components/workspace/citations/artifact-link.tsx index a78957918..119093753 100644 --- a/frontend/src/components/workspace/citations/artifact-link.tsx +++ b/frontend/src/components/workspace/citations/artifact-link.tsx @@ -4,7 +4,7 @@ import { cn } from "@/lib/utils"; import { isSafeHref } from "../messages/markdown-link"; -import { CitationLink } from "./citation-link"; +import { CitationLink, extractReactNodeText } from "./citation-link"; function isExternalUrl(href: string | undefined): boolean { return !!href && /^https?:\/\//.test(href); @@ -33,8 +33,9 @@ export function ArtifactLink(props: AnchorHTMLAttributes) { ); } - if (typeof props.children === "string") { - const match = /^citation:(.+)$/.exec(props.children); + const childrenText = extractReactNodeText(props.children); + if (childrenText !== null) { + const match = /^citation:(.+)$/.exec(childrenText); if (match) { const [, text] = match; return {text}; diff --git a/frontend/src/components/workspace/citations/citation-link.tsx b/frontend/src/components/workspace/citations/citation-link.tsx index a80e71bc4..40c3c3064 100644 --- a/frontend/src/components/workspace/citations/citation-link.tsx +++ b/frontend/src/components/workspace/citations/citation-link.tsx @@ -1,5 +1,5 @@ import { ExternalLinkIcon } from "lucide-react"; -import type { ComponentProps } from "react"; +import { isValidElement, type ComponentProps, type ReactNode } from "react"; import { Badge } from "@/components/ui/badge"; import { @@ -9,6 +9,25 @@ import { } from "@/components/ui/hover-card"; import { cn } from "@/lib/utils"; +/** Extract visible text from renderer-provided ReactNode children. */ +export function extractReactNodeText(node: ReactNode): string | null { + if (typeof node === "string" || typeof node === "number") { + return String(node); + } + if (Array.isArray(node)) { + const text = node + .map(extractReactNodeText) + .filter((value): value is string => value !== null) + .join(""); + return text || null; + } + if (isValidElement(node)) { + const children = (node.props as { children?: ReactNode }).children; + return children === undefined ?

Edit replay resumes from the checkpoint before the edited turn, and that checkpoint predates the rename. Regenerate already guards against exactly this rollback by replaying the current title as graph input; the edit replay path was added later and did not carry the guard over. Replay the title the same way, but only when the replay base already has one. An untitled base belongs to a thread the title middleware has not named yet — pinning the current title there would keep a name generated from the prompt this edit just replaced, and stop the middleware from naming the rewritten turn. --- backend/AGENTS.md | 2 +- backend/app/gateway/routers/thread_runs.py | 35 +++++++--- .../tests/test_thread_regenerate_prepare.py | 69 +++++++++++++++++++ 3 files changed, 96 insertions(+), 10 deletions(-) diff --git a/backend/AGENTS.md b/backend/AGENTS.md index 2f1fd8ec0..f3213c558 100644 --- a/backend/AGENTS.md +++ b/backend/AGENTS.md @@ -441,7 +441,7 @@ Localhost persistence deliberately reads the direct request `Host` and ignores ` | **Artifacts** (`/api/threads/{id}/artifacts`) | `GET /{path}` - serve artifacts; active content types (`text/html`, `application/xhtml+xml`, `image/svg+xml`) are always forced as download attachments to reduce XSS risk; `?download=true` still forces download for other file types | | **Suggestions** (`/api/suggestions`) | `GET /config` - returns global suggestions config boolean; `POST /threads/{id}/suggestions` - generate follow-up questions; rich list/block model content is normalized and inline reasoning (`...`, including unclosed/truncated blocks from reasoning models like MiniMax-M3) is stripped before JSON parsing | | **Input Polish** (`/api/input-polish`) | `POST /` - rewrite a composer draft before it is sent.

The provider converts snapshots to deltas only when a stable completion id is present, isolates interleaved streams by id, and leaves the original usage untouched otherwise. Per-model tracking is lock-protected and cleared on the trailing empty-`choices` frame whether or not that frame carries usage. A soft cap of 1024 ids evicts only entries idle for at least one hour; active streams may temporarily exceed the cap so eviction cannot corrupt their deltas.

MCP tool interceptors can read the same live carrier from `langgraph.config.get_config()["context"]["secrets"]`; see `docs/MCP_SERVER.md`. +- **Admission and redaction ownership**: `services.py::start_run()` validates both legacy request mappings, `metadata.auth_token` and `config.metadata.auth_token`, before any run or thread persistence. `runtime/secret_context.py::redact_config_secrets()` also removes nested config metadata secrets from observable and persisted config copies; historical `RunResponse.kwargs` applies the same redaction non-mutatively, leaving stored `RunRecord` data unchanged. Keep callers on `config.context.secrets` rather than adding another credential carrier. Scheduled task definitions have no durable credential carrier: `ScheduledTaskService` supplies only `scheduled_task_id`, `scheduled_task_run_id`, and `scheduled_trigger` as run metadata. - **Bind (point A+)**: `SkillActivationMiddleware._resolve_secret_bindings` recomputes the injection set (`runtime.context[__active_skill_secrets]`) on every model call from two unioned sources, then REPLACES the key. (1) *Slash*: the run's most recent `/skill` activation, persisted as a source on the run context (only the activated skill's **canonical container path**, never its declared secrets) so the whole tool loop after the activation call keeps the binding; a new activation replaces it. Slash reads the genuine user text via `get_original_user_content_text`; `InputSanitizationMiddleware` preserves it (`ORIGINAL_USER_CONTENT_KEY`), so activation fires even after sanitization. (2) *In-context* (autonomous invocation): skills the model actually loaded in this thread — `ThreadState.skill_context` entries. **Both sources resolve the live registry skill by normalized container path on every call** (`_resolve_registry_skill`) and bind only that skill's own declared secrets — enabled + allowlist checked for both; the `secrets-autonomous: false` opt-out (malformed values fail closed to `false`) additionally gates the in-context path but exempts explicit slash. Resolving by registry — not by trusting the source's stored data — is what makes a caller-forged `__slash_skill_secret_source` harmless (`runtime.context` is caller-mergeable; the gateway also strips caller `__`-keys in `build_run_config`), #3938. Authorization is three-gated regardless of activation style: skill **enabled** by the operator × values **supplied per-request** by the caller (`context.secrets`) × names **declared** in frontmatter (∩ semantics). Because the set is recomputed per call, a skill evicted from `skill_context` (capacity) or a caller that stops supplying a value loses injection on the next call. The injected value always comes from the caller's request, never the host environment (scrubbed first — see below), so a declared name that also exists in the host env is safe: the caller's value wins and the host value is dropped (the #3861 per-user-key-overrides-shared-key case). Missing required secrets are logged once per binding change, not injected; binding changes are recorded as a `middleware:skill_secrets` journal event (skill and secret names only, never values). - **Inject**: `bash_tool` reads the injection set and passes it as `execute_command(env=...)`. Scope is the activation turn/run only — a run without `/skill` activation injects nothing. - **AIO image requirement**: on `AioSandbox` the env path uses the `bash.exec` API (`POST /v1/bash/exec`), which upstream all-in-one-sandbox only ships since `1.9.3` — older images (including a `latest` tag frozen on the `1.0.0.x` line) 404 the whole `/v1/bash/*` namespace. `AioSandbox` detects the 404, remembers the capability gap on the instance, and fails fast with an actionable upgrade error instead of letting the model retry raw 404s; there is deliberately **no** fallback through the legacy shell path because none keeps the secret values out of the command string (#3921). Regression tests: `tests/test_aio_sandbox.py::TestBashExecUnsupportedFailFast`. - **Inherited-env scrub**: `execute_command` no longer leaks the Gateway's `os.environ` to skill subprocesses — `env_policy.build_sandbox_env` drops secret-looking names (`*KEY*`/`*SECRET*`/`*TOKEN*`/`*PASS*`/`*CREDENTIAL*`/`*DSN*` + a connection-string denylist like `DATABASE_URL`/`REDIS_URL`/`GH_PAT`, plus no-flag credential sources like `MYSQL_PWD`/`REDISCLI_AUTH`/`PGPASSFILE`/`PGSERVICEFILE`) so platform credentials never reach a skill; a skill that needs one must declare it. - **Leak surfaces sealed** (verified by a real-gateway e2e run — secret reaches the sandbox but none of these): prompt (value never in a message), trace (`tracing/metadata.py` never copies `context`), checkpoint (secrets live on `runtime.context`, not graph state), audit (journal records names only), stdout (`tools.py::mask_secret_values` redacts injected values from bash output), and **run-record persistence + run API** (`services.py::start_run` stores `redact_config_secrets(body.config)` so `runs.kwargs_json` and `RunResponse.kwargs` never carry the secret). -- **Scope / non-goals**: no persistence/vaulting — values are request-scoped and never stored server-side, so long-lived use means the caller re-supplies `context.secrets` on each request while the skill stays in `skill_context`; subagents do not inherit the injection set; the MCP per-user-credential gap (#3322) is a sibling, not covered here. Tests: `tests/test_skill_request_scoped_secrets.py`. +- **Historical retention**: API response hiding prevents legacy `metadata.auth_token` and `config.metadata.auth_token` from being returned now; it does not delete values already retained in databases, run events, logs, snapshots, exports, or backups. Deployments that ever used either legacy carrier must rotate the credential and clean every retained copy under their retention policy. Restarting or upgrading DeerFlow performs neither action. +- **Scope / non-goals**: no persistence/vaulting — values are request-scoped and never stored server-side, so long-lived use means the caller re-supplies `context.secrets` on each request while the skill stays in `skill_context`; subagents do not inherit the skill injection set. MCP interceptors may independently consume the same supported request-scoped carrier. Tests: `tests/test_skill_request_scoped_secrets.py`, `tests/test_mcp_session_pool.py`. ### Model Factory (`packages/harness/deerflow/models/factory.py`) diff --git a/backend/app/gateway/routers/thread_runs.py b/backend/app/gateway/routers/thread_runs.py index 76f0fa1de..fa9ffbcb4 100644 --- a/backend/app/gateway/routers/thread_runs.py +++ b/backend/app/gateway/routers/thread_runs.py @@ -39,6 +39,7 @@ from app.gateway.run_models import RunCreateRequest from app.gateway.services import build_checkpoint_state_accessor, build_thread_checkpoint_state_accessor, sse_consumer, start_run, wait_for_run_completion from app.gateway.utils import sanitize_log_param from deerflow.runtime import CancelOutcome, RunRecord, RunStatus, serialize_channel_values_for_api +from deerflow.runtime.secret_context import redact_config_secrets, redact_metadata_secrets from deerflow.utils.messages import ORIGINAL_USER_CONTENT_KEY, get_original_user_content_text, message_to_text from deerflow.workspace_changes import get_workspace_changes_response @@ -213,13 +214,17 @@ async def _raise_lease_valid_elsewhere( def _record_to_response(record: RunRecord) -> RunResponse: + kwargs = dict(record.kwargs or {}) + if "config" in kwargs: + kwargs["config"] = redact_config_secrets(kwargs["config"]) + return RunResponse( run_id=record.run_id, thread_id=record.thread_id, assistant_id=record.assistant_id, status=record.status.value, - metadata=record.metadata, - kwargs=record.kwargs, + metadata=redact_metadata_secrets(record.metadata), + kwargs=kwargs, multitask_strategy=record.multitask_strategy, created_at=record.created_at, updated_at=record.updated_at, @@ -1300,7 +1305,23 @@ async def list_run_events( """ event_store = get_run_event_store(request) types = event_types.split(",") if event_types else None - return await event_store.list_events(thread_id, run_id, event_types=types, task_id=task_id, limit=limit, after_seq=after_seq) + events = await event_store.list_events( + thread_id, + run_id, + event_types=types, + task_id=task_id, + limit=limit, + after_seq=after_seq, + ) + return [ + { + **event, + "metadata": redact_metadata_secrets(event.get("metadata")), + } + if isinstance(event, dict) and "metadata" in event + else event + for event in events + ] @router.get("/{thread_id}/runs/{run_id}/workspace-changes") diff --git a/backend/app/gateway/routers/threads.py b/backend/app/gateway/routers/threads.py index 31ac9ac8b..acc67c214 100644 --- a/backend/app/gateway/routers/threads.py +++ b/backend/app/gateway/routers/threads.py @@ -65,6 +65,7 @@ from deerflow.runtime.goal import ( from deerflow.runtime.journal import build_branch_history_seed_events from deerflow.runtime.runs.manager import ConflictError from deerflow.runtime.runs.worker import valid_duration_entry +from deerflow.runtime.secret_context import redact_metadata_secrets from deerflow.runtime.user_context import get_effective_user_id from deerflow.utils.file_io import run_file_io from deerflow.utils.time import coerce_iso, now_iso @@ -349,7 +350,14 @@ class ThreadDeleteResponse(BaseModel): message: str -class ThreadResponse(BaseModel): +class _MetadataRedactingResponse(BaseModel): + @field_validator("metadata", mode="before", check_fields=False) + @classmethod + def _redact_legacy_metadata_secret(cls, value: Any) -> Any: + return redact_metadata_secrets(value) + + +class ThreadResponse(_MetadataRedactingResponse): """Response model for a single thread.""" thread_id: str = Field(description="Unique thread identifier") @@ -402,7 +410,7 @@ class ThreadSearchRequest(BaseModel): return v -class ThreadStateResponse(BaseModel): +class ThreadStateResponse(_MetadataRedactingResponse): """Response model for thread state.""" values: dict[str, Any] = Field(default_factory=dict, description="Current channel values") @@ -472,7 +480,7 @@ class ThreadCompactResponse(BaseModel): total_tokens: int = 0 -class HistoryEntry(BaseModel): +class HistoryEntry(_MetadataRedactingResponse): """Single checkpoint history entry.""" checkpoint_id: str diff --git a/backend/app/gateway/services.py b/backend/app/gateway/services.py index c46d5cb29..bdc0461a8 100644 --- a/backend/app/gateway/services.py +++ b/backend/app/gateway/services.py @@ -61,7 +61,11 @@ from deerflow.runtime.checkpoint_mode import ( from deerflow.runtime.checkpoint_state import graph_state_schema from deerflow.runtime.goal import goal_thread_lock from deerflow.runtime.runs.naming import resolve_root_run_name -from deerflow.runtime.secret_context import redact_config_secrets +from deerflow.runtime.secret_context import ( + LegacyRunMetadataSecretError, + redact_config_secrets, + validate_run_metadata_secrets, +) from deerflow.runtime.stream_modes import normalize_stream_modes from deerflow.runtime.user_context import reset_current_user, set_current_user from deerflow.utils.messages import ORIGINAL_USER_CONTENT_KEY @@ -978,6 +982,14 @@ async def start_run( request : Request FastAPI request — used to retrieve singletons from ``app.state``.

SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

Multi-worker deployments require Postgres, the Redis stream bridge (`stream_bridge.type: redis`), `run_ownership.heartbeat_enabled: true`, and `run_events.backend: db`; process-local memory/JSONL event stores cannot enforce singleton delivery receipts across workers. The bridge shares SSE delivery and bounded `Last-Event-ID` replay across workers. When a valid reconnect cursor has been trimmed, or a subscriber that already established an empty-stream wait falls behind before its first delivery, Memory and Redis emit a machine-readable SSE `gap` event instead of silently returning a partial replay; the Web UI reloads durable thread/event state and resumes from the retained tail. Lease reconciliation marks runs from dead workers as errors, persists their delivery receipts, publishes the terminal stream marker, schedules retained-stream cleanup, and updates the affected thread status. SSE and `/wait` consumers also refresh durable status on heartbeats as a fallback if terminal publication fails. Malformed Redis reconnect IDs live-tail new events instead of replaying the retained buffer, and the rolling retained-buffer TTL (`stream_ttl_seconds`) remains a cleanup safety net rather than a run timeout. IM channel state and other process-local services still need their own multi-worker coordination. > +> Run cancellation may land on any Gateway worker. A non-owning worker now persists the interrupt or rollback request for the live owner, which observes it during lease renewal and performs the normal cancellation flow; load-balancer routing alone no longer produces a 409.

Cancellation latency is therefore bounded by the lease heartbeat interval. +> > With lease heartbeat enabled, a transient RunStore renewal error is retried only until the last confirmed lease expires; the stale worker then cancels local execution and suppresses checkpoint, completion-hook, delivery-receipt, and thread-status finalization.

When multiple Gateway workers share the Docker/AIO or E2B sandbox backend, also configure `sandbox.ownership.type: redis`; E2B uses the leases during background startup and periodic reconciliation so duplicate/orphan cleanup cannot terminate a live peer's sandbox. diff --git a/backend/AGENTS.md b/backend/AGENTS.md index e55ed8b87..03faf4389 100644 --- a/backend/AGENTS.md +++ b/backend/AGENTS.md @@ -508,10 +508,10 @@ JSONL event stores when `GATEWAY_WORKERS > 1`. - Edit-and-rerun visibility is derived from edit replay runs (`metadata.replay_kind="edit"` plus `regenerate_from_run_id`) by `RunManager.list_edit_replay_visibility()`: the newest attempt for each source run is authoritative.

If the admitting caller is cancelled during that post-registration await, `RunManager` drains a shielded replacement cleanup before propagating `CancelledError`, including across repeated cancellation. The cleanup normally persists `interrupted`; if that best-effort transition fails, it retries the active-to-`interrupted` store transition strictly and verifies the result with the replacement's captured owner identity. A concurrent peer terminal transition wins and is synchronized back into the local record rather than being overwritten or deleted. -- Store-only hydrated runs are readable history. In multi-worker mode with heartbeat enabled, cancel on a store-only run can take over (mark `error`) when the owner's lease has expired past the grace window; otherwise it fails with 409 + `Retry-After`.

Fenced workers do not perform subsequent journal/delivery-receipt, progress/completion/status, checkpoint/thread-metadata, or `on_run_completed` writes; the peer recovery path owns the terminal receipt. `RunStore.update_run_completion()` also refuses to replace a different terminal status, closing the peer-takeover/late-finalization race. `grace_seconds` delays peer reclamation for clock skew but is not extra execution time for an owner that can no longer confirm its lease.

In multi-worker mode with heartbeat enabled, cancel on a store-only run records `runs.cancel_action` / `cancel_requested_at` while the owner's lease is live; the first action wins even if a retry later lands on the owner. `RunStore.request_cancel()` and owner completion through `finalize_if_not_cancelled()` are competing active-row CAS operations, so an accepted cancel cannot be overwritten by a later success. `RunStore.renew_lease()` renews and observes the request atomically in the SQL implementation. The owner then executes the normal process-local interrupt/rollback and terminal stream path without transferring the lease. An expired owner is still taken over and marked `error`. `wait=true` and cancel-then-stream use the shared bridge to observe owner finalization; a non-standard process-local bridge returns accepted 202 instead of subscribing to an unreachable stream.

Successful renewals collect durable cancellation actions; after all local renewals have been attempted, heartbeat only signals the corresponding process-local tasks, leaving status writes and rollback cleanup to the worker finalization path. Fenced workers do not perform subsequent journal/delivery-receipt, progress/completion/status, checkpoint/thread-metadata, or `on_run_completed` writes; the peer recovery path owns the terminal receipt. `RunStore.update_run_completion()` also refuses to replace a different terminal status, closing the peer-takeover/late-finalization race. `grace_seconds` delays peer reclamation for clock skew but is not extra execution time for an owner that can no longer confirm its lease. Already-committed remote tool side effects remain outside this local cancellation boundary. - Startup/orphan reconciliation must claim stale active rows with `RunStore.claim_for_takeover()`, not a plain `update_status()`. The final claim re-checks `status` and lease expiry atomically, so a heartbeat renewal between the candidate scan and the recovery write keeps the run active. - Run admission and independent checkpoint writes are first-class thread operations. `runs.operation_kind` distinguishes user-visible `run` rows from internal `checkpoint_write` reservations, while every active kind shares the existing durable active-thread uniqueness constraint. New operation kinds must go through `RunStore.create_thread_operation_atomic()` and `RunManager.reserve_thread_operation()` rather than adding another lock or metadata marker. Live and lease-less reservations are non-interruptible; an expired leased reservation can be reclaimed immediately by interrupt/rollback admission without waiting for orphan reconciliation. Lease-less rows stay fail-closed because the store cannot distinguish a stale row from a live checkpoint writer in another heartbeat-disabled worker; a rare failed delete therefore requires startup reconciliation, and heartbeat-disabled multi-worker deployment remains unsupported. Reservation bodies are attached to their caller task so loss detected by lease renewal cancels the checkpoint writer before it can continue after takeover; the context manager translates that lease-loss cancellation to `ConflictError` after cleanup so Gateway mutation routes return a retryable 409 instead of dropping the HTTP request. The cleanup scope begins immediately after durable admission, including the await that attaches the caller task, so cancellation cannot strand a locally renewed pending reservation. A failed renewal is revalidated under the manager lock before cancellation; if the reservation completed and unregistered while the store update was in flight, its request task must not be cancelled after the checkpoint write. Reservations are excluded from run history/reporting and from run-only helpers such as `list_by_thread()` and `has_inflight()`, release uses the captured owner rather than ambient user context, and local cleanup still runs when the best-effort store delete fails. `RunStore.create_run_atomic()` remains a deprecated compatibility shim for external stores that only admit normal runs; new stores must implement `create_thread_operation_atomic()` to support internal operation kinds. - Gateway checkpoint mutations outside run execution must use `services.reserve_checkpoint_write()`, which composes the process-local thread lock with the durable `checkpoint_write` reservation. Manual compaction, `POST /threads/{id}/state`, and both goal mutation routes (`PUT` / `DELETE /threads/{id}/goal`, including creation of a missing goal checkpoint) use this boundary, so an existing run blocks the write and the reservation blocks new reject/interrupt/rollback runs across workers. @@ -921,6 +921,7 @@ This invokes `alembic revision --autogenerate` against the live ORM models.

message protocol layered on normal chat history. The backend writes request payloads to `ToolMessage.artifact.human_input`, `src/core/messages/human-input.ts` owns the runtime validators/types, and `src/components/workspace/messages/human-input-card.tsx` renders the reusable card. The protocol is versioned on the request side only: v1 covers `free_text` / `choice_with_other`, and v2 adds `form` (typed fields — text/textarea/number/select/multi_select/checkbox/date — with required-field validation in the card). Replies deliberately stay on the v1 response protocol: the form card submits a `response_kind: "text"` reply whose value is the human-readable summary plus one JSON block keyed by stable field names (`buildHumanInputFormSubmissionValue` — the readable part alone is ambiguous because labels/values may contain the separators), so the model can reconstruct the submitted mapping without a structured response kind. The validators reject unknown versions/modes (and field names colliding with JS `Object.prototype` members) so future protocol bumps degrade to the plain-text ToolMessage fallback rather than rendering a broken card. Form values are read through own-property access only (`readHumanInputFormValue`); select fields stay controlled from their empty-string placeholder state through selection; checkbox fields are native `` controls seeded to an explicit `false` (`buildInitialHumanInputFormValues`) so an untouched checkbox submits as "no" while a `required` checkbox keeps must-agree semantics (no HTML `required` attribute — native constraint validation would intercept the custom submit path), and form controls carry label/`htmlFor`, `aria-required` plus a visually-hidden localized "required" marker, and `aria-invalid`/error associations whose error node stays mounted while any field is still invalid. Legacy-fallback closure: `deriveHumanInputThreadState` treats a visible plain human message as answering the latest unanswered request opened before it (only the latest — nothing guarantees a single outstanding request across runs, and closing all would silently swallow older decisions; an older request left open simply becomes the active card again) — an old v1-only frontend degrades a v2 request to text and the user replies through the normal composer without response metadata, and without this rule an upgraded frontend would see that request as still open and lock the composer. `MessageList` owns answered/latest/pending state for visible cards, but derives answered responses from raw `thread.messages` because replies are hidden; pending cards clear when the hidden reply appears, when dispatch is dropped, or when a new `thread.error` reports an async stream failure. Page-level submit callbacks must send a normal human message and put `hide_from_ui: true` plus the response payload in the fourth `sendMessage(..., options)` argument as `options.additionalKwargs`; the third argument remains run context such as `{ agent_name }`. Composer entry points should disable normal bottom input while `hasOpenHumanInputRequest(...)` is true so users answer through the card and preserve response metadata. Tool-calling AI messages can contain user-visible text as well as `tool_calls`. `core/messages/utils.ts` keeps these turns in an `assistant:processing` group, and `components/workspace/messages/message-group.tsx` must render the visible text as a processing step instead of treating the message as only tool metadata. This preserves provider text such as error explanations or "trying another approach" notes during tool-heavy runs. +While the current turn is still loading, a content-only AI message after the latest visible human input also stays in that processing group until the turn settles: a provider may append tool-call chunks to the same message later, and classifying it as a final assistant bubble too early makes the text jump into the steps panel. `MessageGroup` therefore renders processing text even before the first tool call arrives. +The same rule applies after an earlier tool call: a later content-only AI message remains visible after the current last tool-call step while streaming, because that message may itself gain another tool call before the turn settles. Edit-and-rerun is deliberately latest-turn-only. `core/messages/utils.ts::getLatestEditableTurn()` exposes a human turn only when the transcript is idle and the most recent visible turn ends in a terminal assistant message. `core/threads/hooks.ts::editAndRegenerateMessage()` calls `POST /api/threads/{id}/runs/edit-regenerate/prepare`, submits the returned replacement message/checkpoint/metadata through the same LangGraph stream path as regenerate, optimistically hides the superseded message ids, and clears the optimistic replacement once the persisted replacement arrives. diff --git a/frontend/src/components/workspace/messages/message-group.tsx b/frontend/src/components/workspace/messages/message-group.tsx index 82e647534..bc55194be 100644 --- a/frontend/src/components/workspace/messages/message-group.tsx +++ b/frontend/src/components/workspace/messages/message-group.tsx @@ -109,6 +109,15 @@ function MessageGroupComponent({ } return []; }, [lastToolCallStep, steps]); + const afterLastToolCallAssistantTextSteps = useMemo(() => { + if (!lastToolCallStep) { + return []; + } + const index = steps.indexOf(lastToolCallStep); + return steps + .slice(index + 1) + .filter((step) => step.type === "assistantText"); + }, [lastToolCallStep, steps]); const collapsibleAboveLastToolCallSteps = useMemo( () => aboveLastToolCallSteps.filter((step) => step.type !== "assistantText"), @@ -314,22 +323,28 @@ function MessageGroupComponent({ > )} - {lastToolCallStep && ( + {(lastToolCallStep ?? + steps.some((step) => step.type === "assistantText")) && ( - {(showAbove - ? aboveLastToolCallSteps - : aboveLastToolCallSteps.filter( - (step) => step.type === "assistantText", - ) + {(lastToolCallStep + ? showAbove + ? aboveLastToolCallSteps + : aboveLastToolCallSteps.filter( + (step) => step.type === "assistantText", + ) + : steps.filter((step) => step.type === "assistantText") ).flatMap(renderStep)} - {renderDebugSummary( - lastToolCallStep.messageId, - steps.indexOf(lastToolCallStep), - )} {lastToolCallStep && ( - - {renderToolCall(lastToolCallStep, { isLast: true })} - + <> + {renderDebugSummary( + lastToolCallStep.messageId, + steps.indexOf(lastToolCallStep), + )} + + {renderToolCall(lastToolCallStep, { isLast: true })} + + {afterLastToolCallAssistantTextSteps.flatMap(renderStep)} + )} )} @@ -933,7 +948,7 @@ function convertToSteps(messages: Message[]): CoTStep[] { for (const [messageIndex, message] of messages.entries()) { if (message.type === "ai") { const content = extractContentFromMessage(message); - if (content && message.tool_calls?.length) { + if (content) { steps.push({ id: `${message.id ?? `ai-${messageIndex}`}-content`, messageId: message.id, diff --git a/frontend/src/components/workspace/messages/message-list.tsx b/frontend/src/components/workspace/messages/message-list.tsx index f781df040..0c018a6b2 100644 --- a/frontend/src/components/workspace/messages/message-list.tsx +++ b/frontend/src/components/workspace/messages/message-list.tsx @@ -180,7 +180,9 @@ function useStableMessageGroups( const previousGroupsRef = useRef([]); const previousIsLoadingRef = useRef(false); return useMemo(() => { - const nextGroups = getMessageGroups(messages); + const nextGroups = getMessageGroups(messages, { + isCurrentTurnLoading: isLoading, + }); const previousGroups = previousGroupsRef.current; const activeGroupIndex = isLoading || previousIsLoadingRef.current ? nextGroups.length - 1 : -1; diff --git a/frontend/src/core/messages/utils.ts b/frontend/src/core/messages/utils.ts index 755e05535..0b0a09517 100644 --- a/frontend/src/core/messages/utils.ts +++ b/frontend/src/core/messages/utils.ts @@ -33,12 +33,25 @@ const HIDDEN_CONTROL_MESSAGE_NAMES = new Set([ "todo_completion_reminder", ]); -export function getMessageGroups(messages: Message[]): MessageGroup[] { +export function getMessageGroups( + messages: Message[], + { isCurrentTurnLoading = false }: { isCurrentTurnLoading?: boolean } = {}, +): MessageGroup[] { if (messages.length === 0) { return []; } const groups: MessageGroup[] = []; + let currentTurnStartIndex = -1; + if (isCurrentTurnLoading) { + for (let index = messages.length - 1; index >= 0; index--) { + const message = messages[index]; + if (message?.type === "human" && !isHiddenFromUIMessage(message)) { + currentTurnStartIndex = index; + break; + } + } + } // Returns the last group if it can still accept tool messages // (i.e. it's an in-flight processing group, not a terminal human/assistant group). @@ -55,7 +68,7 @@ export function getMessageGroups(messages: Message[]): MessageGroup[] { return null; } - for (const message of messages) { + for (const [messageIndex, message] of messages.entries()) { if (isHiddenFromUIMessage(message)) { continue; } @@ -127,8 +140,20 @@ export function getMessageGroups(messages: Message[]): MessageGroup[] { // panel above the bubble paints the identical reasoning a second time // (#3868).

Reasoning From 9a43d8276d22a3f2308924a6b3a5d5aa3fe7939a Mon Sep 17 00:00:00 2001 From: Aari Date: Tue, 28 Jul 2026 22:12:27 +0800 Subject: [PATCH 10/33] fix(gateway): replay edit and rerun from a settled checkpoint (#4534) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Editing the only turn of a thread reran the original prompt: the model answered the question the edit was replacing while the UI showed the edited text, and the edit vanished on reload. The replay-base lookup decided whether a checkpoint predates the target user message by message id alone. DynamicContextMiddleware re-keys the first user turn to `{id}__user` mid-run, so every checkpoint written before it holds the same prompt under an id the lookup cannot match. The scan walked past those and anchored inside the run that produced the turn — a checkpoint that still contains the original prompt and owns the injection node's pending writes, which the replay then re-added after the edited message. Require the replay base to be a settled checkpoint (no pending tasks) in both the lineage walk and the chronological fallback. That rule is middleware agnostic: the first turn now anchors on the thread's empty initial checkpoint and later turns on the previous run's tail, which also drops the existing reliance on LangGraph discarding a stale `__start__` write. Edit replay additionally passes `head_checkpoint` so it resolves its base lineage-first like regenerate does, and a replayed user message is restored to its pre-swap id: replaying `{id}__user` into a state that has no reminder yet makes the middleware treat the turn as already injected and silently drops its date and memory block. Frontend: a prepared replay masks the turn it supersedes, so the optimistic-message baseline is taken from the post-mask human count. The pre-mask count can never be exceeded when the replay puts exactly one human message back, and on the first turn the runtime re-keys the replacement message so identity comparison cannot stand in for the count.

Gateway `services.py` builds and passes the accessor; thread-owned reads (state/history/regeneration) must use `build_thread_checkpoint_state_accessor` so the recorded assistant's middleware schema materializes every channel. `history(limit)` semantics: `0` means zero items (explicit empty), `None` means unlimited — do not pass `limit=0` through to `graph.get_state_history`. Assistant metadata lookup is fail-closed for mutation accessors so a store outage cannot silently select the default schema and discard extension channels. In `full` mode the read path degrades to a raw checkpointer read (`_RawCheckpointReadAccessor`) when the agent factory cannot build the graph (bad model config, MCP outage) — full checkpoints carry complete `channel_values`, so reads don't need the graph; degraded snapshots take `created_at` from the standard checkpoint `ts` field, falling back to metadata only for compatibility. The delta gate still applies on the degraded path; `next`/`tasks` degrade to empty and thread status falls back to the stored status because task presence is not derivable, while delta mode has no fallback (materialization needs the channel table). -**Replay checkpoint lookup prefers lineage and degrades only for an explicitly missing legacy parent link.** Branch and regenerate paths first walk `parent_config`, which prevents a global chronological scan from selecting a sibling created by regeneration. `CheckpointParentMissingError` alone enables the bounded newest-first history fallback in `app/gateway/checkpoint_lineage.py`; cycles, dangling/non-addressable parents, target mismatches, and depth exhaustion raise `CheckpointLineageIntegrityError` and fail closed instead of selecting a sibling.

Regenerate source-run lookup uses the current thread's exact event, then the server-stamped `run_id` on the copied human message, then verified RunManager content matching; it does not read parent-thread events. When an interrupted response was streamed but never checkpointed, regeneration accepts only the latest visible human message's server-stamped `run_id` after verifying that it belongs to the same thread and still has `interrupted` status. Storage or checkpoint-mode failures are not treated as a missing base and still fail closed. **A delta-mode run cannot fork; `runtime/runs/worker.py` linearizes the resume instead.** Resuming from an older checkpoint (regenerate, or any client-supplied `checkpoint`) forks the lineage, and delta state for a fork is not materializable: `BaseCheckpointSaver.get_delta_channel_history` — and the bespoke overrides in `InMemorySaver`/`PostgresSaver` — collect **every** `pending_writes` entry stored on each on-path ancestor, but a shared parent also carries the writes of the sibling child that was abandoned. Those writes replay into the fork, so the run starts from a message list still containing the answer it was supposed to replace (#4458: regenerating in a branched thread showed the superseded assistant message beside the new one after a reload; reproduced on postgres, sqlite, and the in-memory saver). Write-to-child ownership belongs to the upstream delta contract, so DeerFlow does not reimplement the walk: `_linearize_delta_checkpoint_resume` materializes the requested checkpoint's complete state and writes every channel onto the **current head** (which has no siblings) through the state mutation graph, using `Overwrite` for reducer channels and resetting newer head-only channels to their schema default (or `None` when no constructible default exists); it then drops the `checkpoint_id` selector and lets the run proceed linearly, while the abandoned turn stays in history as the rewritten head's ancestry. The worker holds `_checkpoint_thread_lock` across `_capture_rollback_point` and the optional linear rewrite, making the rollback snapshot and rewrite atomic with graph streaming and the preceding run's duration-metadata checkpoint write. Capture preserves the complete real pre-run state; cancel-with-rollback then linearly replaces the current delta head with that captured state rather than forking the now-shared pre-run checkpoint, so the abandoned turn is restored without replaying the resume sibling's writes. The worker also recomputes the current-run message boundary from the rewritten state and fails closed (an unreadable resume checkpoint raises rather than falling back to the corrupt fork). `full` mode keeps forking — its checkpoints carry complete `channel_values` and need no replay — so LangGraph branching semantics are unchanged there.

Thread rename uses the same serialized state-write route; the rename dialog stays open and surfaces the server error when an active run returns 409. -Human input requests are a structured message protocol layered on normal chat history. The backend writes request payloads to `ToolMessage.artifact.human_input`, `src/core/messages/human-input.ts` owns the runtime validators/types, and `src/components/workspace/messages/human-input-card.tsx` renders the reusable card. The protocol is versioned on the request side only: v1 covers `free_text` / `choice_with_other`, and v2 adds `form` (typed fields — text/textarea/number/select/multi_select/checkbox/date — with required-field validation in the card). Replies deliberately stay on the v1 response protocol: the form card submits a `response_kind: "text"` reply whose value is the human-readable summary plus one JSON block keyed by stable field names (`buildHumanInputFormSubmissionValue` — the readable part alone is ambiguous because labels/values may contain the separators), so the model can reconstruct the submitted mapping without a structured response kind. The validators reject unknown versions/modes (and field names colliding with JS `Object.prototype` members) so future protocol bumps degrade to the plain-text ToolMessage fallback rather than rendering a broken card. Form values are read through own-property access only (`readHumanInputFormValue`); select fields stay controlled from their empty-string placeholder state through selection; checkbox fields are native `` controls seeded to an explicit `false` (`buildInitialHumanInputFormValues`) so an untouched checkbox submits as "no" while a `required` checkbox keeps must-agree semantics (no HTML `required` attribute — native constraint validation would intercept the custom submit path), and form controls carry label/`htmlFor`, `aria-required` plus a visually-hidden localized "required" marker, and `aria-invalid`/error associations whose error node stays mounted while any field is still invalid. Legacy-fallback closure: `deriveHumanInputThreadState` treats a visible plain human message as answering the latest unanswered request opened before it (only the latest — nothing guarantees a single outstanding request across runs, and closing all would silently swallow older decisions; an older request left open simply becomes the active card again) — an old v1-only frontend degrades a v2 request to text and the user replies through the normal composer without response metadata, and without this rule an upgraded frontend would see that request as still open and lock the composer. `MessageList` owns answered/latest/pending state for visible cards, but derives answered responses from raw `thread.messages` because replies are hidden; pending cards clear when the hidden reply appears, when dispatch is dropped, or when a new `thread.error` reports an async stream failure. Page-level submit callbacks must send a normal human message and put `hide_from_ui: true` plus the response payload in the fourth `sendMessage(..., options)` argument as `options.additionalKwargs`; the third argument remains run context such as `{ agent_name }`. Composer entry points should disable normal bottom input while `hasOpenHumanInputRequest(...)` is true so users answer through the card and preserve response metadata. +Human input requests are a structured message protocol layered on normal chat history.

Composer entry points remain enabled while a human-input request is open; a normal visible message intentionally bypasses the card and starts the next run without structured response metadata. Tool-calling AI messages can contain user-visible text as well as `tool_calls`. `core/messages/utils.ts` keeps these turns in an `assistant:processing` group, and `components/workspace/messages/message-group.tsx` must render the visible text as a processing step instead of treating the message as only tool metadata. This preserves provider text such as error explanations or "trying another approach" notes during tool-heavy runs. While the current turn is still loading, a content-only AI message after the latest visible human input also stays in that processing group until the turn settles: a provider may append tool-call chunks to the same message later, and classifying it as a final assistant bubble too early makes the text jump into the steps panel. `MessageGroup` therefore renders processing text even before the first tool call arrives. diff --git a/frontend/src/app/workspace/agents/[agent_name]/chats/[thread_id]/page.tsx b/frontend/src/app/workspace/agents/[agent_name]/chats/[thread_id]/page.tsx index 78d76de19..b405fdaab 100644 --- a/frontend/src/app/workspace/agents/[agent_name]/chats/[thread_id]/page.tsx +++ b/frontend/src/app/workspace/agents/[agent_name]/chats/[thread_id]/page.tsx @@ -401,7 +401,6 @@ export default function AgentChatPage() { disabled={ env.NEXT_PUBLIC_STATIC_WEBSITE_ONLY === "true" || isUploading || - hasOpenHumanInputCard || (!isNewThread && isHistoryLoading) } onContextChange={(context) => diff --git a/frontend/src/app/workspace/agents/new/page.tsx b/frontend/src/app/workspace/agents/new/page.tsx index bbbb0fa34..7f2d4ee4c 100644 --- a/frontend/src/app/workspace/agents/new/page.tsx +++ b/frontend/src/app/workspace/agents/new/page.tsx @@ -40,11 +40,9 @@ import { import { useI18n } from "@/core/i18n/hooks";

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(lark): sidecar credential broker for sandbox lark-cli (Pattern B) Removes the plaintext Lark credential mounts (appSecret + OAuth tokens) from the sandbox container. A long-running broker sidecar owns lark-cli and the per-user config/data dirs and serves the command surface over Pod loopback; the sandbox gets only a forwarding shim on PATH, so the raw credential files never exist in the sandbox filesystem. - lark_broker.py: stdlib-only loopback broker (argv passthrough with shell=False, server-injected credential env, bounded I/O) + shim script constant + install-shim mode. - docker/lark-cli-broker: init(install-shim) + serve image. - provisioner: LARK_CLI_BROKER_IMAGE + provision_lark_cli_broker → shim init container + lark-cli-broker sidecar (config/data mounted sidecar-only); credentials dropped from the sandbox container; /api/capabilities reports lark_cli_broker_image. Broker supersedes the Pattern A init-container binary when both are configured. - gateway: lark_cli_env_overlay(broker=True) omits config/data env; sandbox_lark_broker_active() TTL-cached mode resolver; broker added to sandbox_runtime_mode / readiness and the settings UI. Opt-in and off by default (empty LARK_CLI_BROKER_IMAGE ⇒ no change). Closes #4338 * fix(lark): address Pattern B broker review findings (#4501) Follow-up to the sidecar credential broker addressing the PR #4501 review: - shim: split the on-PATH lark-cli into a /bin/sh launcher + Python shim body so broker mode fails loudly (exit 127, actionable message) instead of ENOEXEC when the sandbox image ships no python3; interpreter pinnable via DEERFLOW_LARK_BROKER_PYTHON. Launcher bakes in the shim's absolute path since $0 is the bare command name when run off PATH. - broker: drop the dead cwd payload field (broker can't see the sandbox FS) and document the command-surface-only / no-file-IO limitation. - broker: return a structured 500 JSON on unexpected exec errors so the shim gets a meaningful message, not an opaque transport failure; set a handler socket timeout to bound slow/stuck connections. - broker: add an opt-in DEERFLOW_LARK_BROKER_DENY_SUBCOMMANDS denylist that refuses secret-dumping subcommands before spawning the binary, forwarded from the provisioner sidecar. - gateway: tighten the per-bash-call broker probe timeout (1.5s) and cache negatives longer (300s) so non-broker remote-provisioner users don't pay a latency hit; guard the mode cache with a lock; drop the dead _probe_provisioner_lark_cli_init_image wrapper. - docs: remove the broken design-doc link from the broker README. Adds tests for launcher python resolution, cwd omission, denylist enforcement, 500-on-error, hot-path probe timeout + negative caching, and provisioner denylist-env wiring. --- backend/AGENTS.md | 2 +- backend/app/gateway/routers/integrations.py | 2 +- .../aio_sandbox/aio_sandbox_provider.py | 23 + .../deerflow/community/aio_sandbox/backend.py | 5 + .../community/aio_sandbox/local_backend.py | 5 +- .../community/aio_sandbox/remote_backend.py | 22 +- .../deerflow/integrations/lark_broker.py | 457 ++++++++++++++++++ .../harness/deerflow/integrations/lark_cli.py | 121 ++++- .../harness/deerflow/sandbox/tools.py | 9 +- backend/tests/test_aio_sandbox_provider.py | 42 +- backend/tests/test_lark_broker.py | 357 ++++++++++++++ backend/tests/test_lark_cli_integration.py | 91 +++- backend/tests/test_provisioner_pvc_volumes.py | 143 ++++++ backend/tests/test_remote_sandbox_backend.py | 5 +- docker/docker-compose-dev.yaml | 3 + docker/docker-compose.yaml | 5 + docker/lark-cli-broker/Dockerfile | 79 +++ docker/lark-cli-broker/README.md | 111 +++++ docker/lark-cli-broker/entrypoint.sh | 29 ++ docker/provisioner/README.md | 1 + docker/provisioner/app.py | 233 +++++++-- .../settings/integrations-settings-page.tsx | 12 +- frontend/src/core/i18n/locales/en-US.ts | 1 + frontend/src/core/i18n/locales/types.ts | 1 + frontend/src/core/i18n/locales/zh-CN.ts | 1 + frontend/src/core/integrations/lark/types.ts | 3 +- 26 files changed, 1699 insertions(+), 64 deletions(-) create mode 100644 backend/packages/harness/deerflow/integrations/lark_broker.py create mode 100644 backend/tests/test_lark_broker.py create mode 100644 docker/lark-cli-broker/Dockerfile create mode 100644 docker/lark-cli-broker/README.md create mode 100644 docker/lark-cli-broker/entrypoint.sh diff --git a/backend/AGENTS.md b/backend/AGENTS.md index 3ad5ed03d..1de991c6d 100644 --- a/backend/AGENTS.md +++ b/backend/AGENTS.md @@ -710,7 +710,7 @@ E2B output sync records remote file versions and actual host file metadata in a - `skills/describe.py` — `build_describe_skill_tool(catalog)` builds the `describe_skill` tool as a closure; `build_skill_search_setup(skills, enabled, ...)` produces a `SkillSearchSetup(describe_skill_tool, skill_names)` that is wired into both the LangGraph agent factory (`agent.py`) and the embedded client (`client.py`). - **Slash activation**: `/skill-name task` loads that enabled skill's `SKILL.md` for the current model call only.

The sidecar credential-broker (Pattern B, issue #4338) is the fix that removes these plaintext mounts from sandbox execution: set `LARK_CLI_BROKER_IMAGE` on the provisioner (see `docker/lark-cli-broker/`) and the Gateway sends `provision_lark_cli_broker` on sandbox create. The provisioner then runs a `lark-cli-broker` sidecar that owns the per-user `config`/`data` (mounted into the **sidecar only**, at `/var/lark/{config,data}`) and serves the `lark-cli` command surface on Pod loopback (`http://127.0.0.1:8788`); a shim init container (`install-shim`) writes a forwarding `lark-cli` into the shared runtime `emptyDir`, so the sandbox gets `DEERFLOW_LARK_BROKER_URL` + a shim on PATH but **no** credential files. The on-PATH `bin/lark-cli` is a `/bin/sh` launcher that resolves a Python 3 interpreter and execs the Python shim body (`bin/lark-cli-shim.py`) beside it, so broker mode does not silently ENOEXEC on a sandbox image without a `#!/usr/bin/env python3`-resolvable interpreter — it fails loudly (exit 127, actionable message) and can be pinned with `DEERFLOW_LARK_BROKER_PYTHON`. The broker runs `lark-cli` in the sidecar's cwd and cannot see the sandbox filesystem, so cwd is intentionally **not** forwarded and file-I/O subcommands relative to the sandbox cwd are unsupported (command surface only). An optional `DEERFLOW_LARK_BROKER_DENY_SUBCOMMANDS` denylist (comma-separated command prefixes, forwarded from the provisioner) lets the broker refuse secret-dumping subcommands before spawning the binary. `lark_cli_env_overlay(broker=True)` therefore omits `LARKSUITE_CLI_CONFIG_DIR`/`DATA_DIR`; `sandbox_lark_broker_active()` (TTL-cached provisioner `/api/capabilities` probe, tight timeout + longer negative caching on the bash hot path) selects broker vs. binary mode for both the bash env overlay and status. `DEER_FLOW_LARK_CLI_SANDBOX_RUNTIME_DIR` supplies a validated, symlink-free pre-staged runtime for air-gapped deployments. For the remote provisioner (K8s), the runtime binary is otherwise provisioned by an optional init container + shared `emptyDir` (Pattern A): set `LARK_CLI_INIT_IMAGE` on the provisioner (see `docker/lark-cli-init/`) and the Gateway sends `provision_lark_cli_runtime` on sandbox create once the pack is installed, so remote installs skip the Gateway-side GitHub download entirely. Broker (Pattern B) supersedes the init-container binary (Pattern A) when both images are configured. `get_lark_integration_status(check_runtime=True)` surfaces `sandbox_runtime_mode` (`none` / `gateway-download` / `init-container` / `broker`) and `sandbox_runtime_ready` (remote modes read the provisioner `GET /api/capabilities`: `lark_cli_init_image` / `lark_cli_broker_image`) so a green UI can't hide a chat-time `lark-cli: command not found`. Cheap status probes are explicitly not live-verified; users authorize or reconnect through the browser device-flow endpoints instead of running terminal commands. - **SkillScan**: `packages/harness/deerflow/skills/skillscan/` is the native deterministic scanner for `.skill` archives and agent-managed skill writes. It runs offline before the LLM scanner, emits structured findings (`rule_id`, `severity`, `file`, `line`, `message`, `remediation`, redacted `evidence` — category/analyzer are encoded in the `rule_id` prefix), blocks `CRITICAL`, and passes warning findings into `scan_skill_content()`. `scan_archive_preflight()` / `scan_skill_dir()` are pure sync functions (dispatch off the event loop); `enforce_static_scan()` applies the blocking policy and the `skill_scan.enabled` kill switch. The Python instance-client signal deliberately follows only a one-level, same-scope evidence chain (PR #4265 review): a proven imported constructor bound to a simple name, optional name-to-name alias propagation, rebinding invalidation, and a constructor-supported outbound method or context-manager use; bare canonical-looking names never fall back to module identity. Nested scopes never inherit client handles and inherit only constructor aliases proven stable by a binding-only enclosing-scope prepass. Comprehensions, walrus-bearing statements, annotations, executable expressions inside complex binding targets, unsupported operations, and ambiguous flows produce no finding from this signal; skipped constructs invalidate all names they may bind, while representative false negatives are pinned by `test_python_declared_false_negatives_stay_unreported`. Compound bodies are walked from isolated copies so wrapping code in `if True:` is not a bypass, while copied scope entries, binding-only prepasses, and AST visits consume a deterministic work budget and the walk stops after its first sink. Budget or recursion exhaustion skips only this best-effort signal and retains deterministic findings already collected for the file. Do not add Semgrep/OpenGrep or YAML rule-engine dependencies to the core path; Phase 1 rule specs live in Python constants next to their analyzers in `skillscan/orchestrator.py`. - **Skill Review Core**: `packages/harness/deerflow/skills/review/` provides read-only package snapshots, deterministic facts, resource/eval analysis, report rendering, and the CLI (`python -m deerflow.skills.review.cli`). It reuses the shared frontmatter helper and SkillScan; it must not import `app.*`, execute target scripts, install dependencies, or call networks. JSON contracts live in `contracts/skill_review/`. The `review_skill_package` built-in tool labels results with `review_subject_entry` and never `skill_context_entry`, so reviewing a target does not activate it, bind its `required-secrets`, or apply its `allowed-tools`.

On standalone Agent Server runs, server-owned auth identity is also resolved during lead-agent construction, normalized through `make_safe_user_id` for DeerFlow storage, and explicitly reused for custom-agent config/SOUL, user skills, skill policy, and prompt assembly; ordinary client `user_id` values cannot override `langgraph_auth_user_id`. On the embedded Gateway path, `inject_authenticated_user_context` removes client-supplied `langgraph_auth_user` / `langgraph_auth_user_id` from both RunnableConfig sections before graph construction, so those reserved fields cannot impersonate Agent Server auth. - `memory.mode: tool` skips `MemoryMiddleware` and registers `memory_search`, `memory_add`, `memory_update`, and `memory_delete` on the agent. The model decides when to search, add, update, or delete facts; this is opt-in/experimental and should not be described as better than middleware mode without eval evidence. - Both modes share `FileMemoryStorage`, per-user/per-agent isolation, prompt injection, manual CRUD primitives, and the updater backend. - Middleware mode queue debounces (30s default), batches updates, and commits global summaries plus the selected/default agent's fact delta through a user-level lock, optimistic user-memory revisions, per-fact revisions, and a recoverable target-file journal. Only explicitly marked point operations may rebase a stale shared revision, and only while every addressed fact still satisfies its original absent/revision precondition. Snapshot-derived clear/trim/consolidation operations instead reload the complete document and recompute their intent on a manifest conflict, with a bounded retry. Typed manifest/fact conflict subclasses keep that decision independent of exception text, and same-ID creates and stale same-fact writes fail. Scope-lock objects are weakly cached so inactive users do not grow a process-lifetime map. Cache validation does not scale with the fact-file count: its token combines the shared JSON's `(mtime_ns, size, revision)`, so the persisted revision invalidates stale caches even when a coarse-mtime filesystem reports identical metadata for same-size writes; direct out-of-band Markdown edits require `reload()`. Atomic replacement also syncs the parent directory on POSIX so the rename is durable. DeerMem translates private storage conflict/corruption exceptions to the backend-neutral MemoryManager contract; the Gateway maps them to HTTP 409 and a stable HTTP 500 response respectively. A normal default-manager read automatically migrates legacy facts from the global JSON into `__default__`; it also adopts the earlier implicit `lead-agent` fact bucket only when that directory has no custom-agent `config.yaml`, and rejects unexpected files instead of deleting them. The v1-to-v2 migration is one-way for the running application: operators must stop DeerFlow and snapshot the configured storage root before upgrade. Before any destructive v2 write, every migrated JSON source is durably retained as `{manifest_filename}.v1.bak`; a missing-write or mismatched existing backup aborts without modifying v1 data. Legacy per-agent JSON is deleted only after its non-empty summaries are safely adopted or confirmed identical; summary conflicts keep the source file and fail loudly. diff --git a/backend/app/gateway/services.py b/backend/app/gateway/services.py index 7409c187d..2e2ffe0fb 100644 --- a/backend/app/gateway/services.py +++ b/backend/app/gateway/services.py @@ -307,12 +307,21 @@ _CONTEXT_INTERNAL_CALLER_KEYS: frozenset[str] = frozenset({"non_interactive"}) # Server-owned authorization identity fields.

The reverse direction is allowed: delta-mode processes read full checkpoints transparently (old full checkpoints seed the delta channel), so full → delta is the smooth migration path; delta → full requires materializing/converting the data first.

In `full` mode, cancel-with-rollback forks from the pre-run checkpoint via the mutation graph and inherits non-message channels from that parent. In `delta` mode, forking is unsafe once the cancelled path has attached sibling writes to the pre-run checkpoint, so rollback replaces every captured channel on the current head, using `Overwrite` for reducers and schema defaults for current-head-only channels. Both modes reattach only the captured pre-run pending writes to the restored checkpoint.

It does *not* raise: at the hard-stop threshold it strips the in-flight turn's tool calls, forces `finish_reason="stop"`, and lets the run complete naturally with a final answer. **Loop axis**: `LoopDetectionMiddleware` (attached at the same point) catches repeated identical tool-call sets — or one tool *type* called many times with varying args — and its hard-stop likewise strips `tool_calls` and forces a final answer without raising, recording `loop_capped`. Each guard exposes its cap on a per-`run_id` `consume_stop_reason(run_id)` accessor; `_aexecute` collects **every** middleware with that method (duck-typed via `hasattr`, so the executor has no import coupling to the guard classes) and surfaces the first non-`None` reason — adding a future guard needs no executor change. **Surfacing**: whichever axis fired, `_aexecute` stamps a normal status plus an additive reason — `completed` + `stop_reason=token_capped|turn_capped|loop_capped` when a usable final answer (or partial recovered from the last streamed chunk via `_extract_final_result` → `utils/messages.py::message_content_to_text`, returning a `"No response Generated"` sentinel when no text survived) was produced; `failed` + `stop_reason=turn_capped` when nothing usable survived. `SubagentResult.stop_reason` flows through `task_tool.py::_task_result_command` → `format_subagent_result_message` (renders `Task Succeeded (capped: ...)` / `Task failed (capped: ...)`) and `make_subagent_additional_kwargs`, which stamps the additive `subagent_stop_reason` key alongside the normal `subagent_status`. **Why additive, not an enum**: a new status value would break v1 consumers; an optional field is ignored by older frontends and ledger readers, so the cross-language contract (`contracts/subagent_status_contract.json` v2 + `subagents/status_contract.py` + `frontend/.../subtask-result.ts`, pinned by `test_status_values_match_contract` / `test_stop_reason_values_match_contract`) stays backward-compatible. The durable delegation ledger captures `stop_reason` onto the entry and renders model-facing guidance ("hit a guardrail cap with a partial result; reuse it, retry tighter, or raise the per-agent budget (`max_turns` / `token_budget`)") so the lead reuses a capped completion knowingly instead of mistaking it for a clean one. (Phase 1 shipped this surfacing as a `MAX_TURNS_REACHED` status enum in #3949; Phase 2 replaced that enum with the additive `stop_reason` field per the agreed design — the `max_turns_reached` status value and `SubagentStatus.MAX_TURNS_REACHED` are gone.) **Context compaction (#3875 Phase 3, #4039)**: subagents inherit `DeerFlowSummarizationMiddleware` via `build_subagent_runtime_middlewares`, gated on the **same** `summarization.enabled` switch the lead reads (one config covers both chains; trigger/keep/model/prompt come from the shared `summarization` config so they cannot drift). The subagent builder attaches `DurableContextMiddleware` immediately before summarization, using the same skills path/read-tool settings as the lead chain. Compaction stores the generated summary in `ThreadState.summary_text` rather than as a `messages` item; the durable-context wrapper therefore projects it into the next model request as guarded hidden human data. This is required when a message-count keep policy preserves only an assistant tool-call plus its tool results: without the injected summary the next request begins with assistant/tool history and strict OpenAI-compatible providers can reject it. Because `DurableContextMiddleware` inserts a second `SystemMessage(authority_contract)` after the subagent's leading system prompt, the builder also appends `SystemMessageCoalescingMiddleware` innermost (mirroring the lead chain, appended after the optional summarization middleware so it is unconditionally last) to merge every `SystemMessage` into one leading `system_message` — otherwise the durable fix would trade #4039's assistant-first HTTP 400 for a duplicate-system 400 on the same strict backends (#4040). The factory is called with `skip_memory_flush=True` on the subagent path: the lead's `memory_flush_hook` (attached when `memory.enabled`) flushes pre-compaction messages into durable memory keyed by `thread_id`, and subagents share the parent's `thread_id`, so without skipping the hook a subagent's internal turns would pollute the **parent** thread's durable memory. Placement differs from the lead chain (lead appends summarization *before* the guard trio; subagent appends it *after*) — benign because the middleware implements only `before_model` (compaction) with no `after_model`/`consume_stop_reason`, so it cannot disturb the Phase 2 guard-cap stop-reason channel. Compaction rewrites the messages channel via `RemoveMessage(id=REMOVE_ALL_MESSAGES)`, which shrinks `len(messages)` below the step-capture cursor mid-run; `capture_new_step_messages` (see Step capture below) resets the cursor to the new tail on contraction so steps appended after the compaction point are not silently dropped. **Step capture & persistence (#3779)**: `executor.py` captures both assistant turns (`AIMessage`) **and** tool outputs (`ToolMessage`) via `subagents/step_events.py::capture_new_step_messages`, which walks the *newly-appended tail* of each `stream_mode="values"` chunk (not just `messages[-1]`) so a multi-tool-call turn — where LangGraph's `ToolNode` appends several `ToolMessage`s in one super-step — keeps every tool output instead of dropping all but the last. `runtime/runs/worker.py::_SubagentEventBuffer` additionally persists these `task_*` custom events to the `RunEventStore` as `subagent.start`/`subagent.step`/`subagent.end` (`category="subagent"`, `task_id` in `metadata`). It **batches** writes via `put_batch` (flushing on a terminal `subagent.end`, at `FLUSH_THRESHOLD` events, and in the worker's `finally`) rather than one `put()` per step, since `put()` is a documented low-frequency path (per-thread advisory lock per call) and a deep subagent (`max_turns=150`) emits hundreds of steps on the hot stream loop. `subagent_run_event` rejects malformed chunks that lack a non-empty `task_id`; running chunks additionally require a non-negative integer `message_index` and a message object, so persisted records always satisfy the required lifecycle envelope. `build_subagent_step` caps both the per-step `text` and each tool call's serialized `args` at `SUBAGENT_STEP_MAX_CHARS` (flagged `truncated` / `args_truncated`) so a large `write_file`/`bash` payload can't produce an unbounded row. The dedicated category keeps them out of `list_messages` (the thread feed) while `list_events` returns them for the frontend's fetch-on-expand backfill. `list_events` accepts `task_id` (filters on `metadata["task_id"]` — SQL-side in `DbRunEventStore` via `event_metadata["task_id"].as_string()`, in-memory in the JSONL/memory stores) plus an `after_seq` forward cursor, so the card pages through one subagent's steps without the run-wide `limit` truncating the tail (no schema migration: the filter rides the existing run-scoped index). `step_events.py` is a pure, unit-tested layer (`build_subagent_step` / `subagent_run_event`). **History contraction (#3875 Phase 3)**: `capture_new_step_messages` assumes append-only growth, but `DeerFlowSummarizationMiddleware` rewrites the messages channel via `RemoveMessage(id=REMOVE_ALL_MESSAGES)`, shrinking `len(messages)` below the cursor mid-run. On contraction (`total < processed_count`) the cursor resets to the new tail; `capture_step_message`'s id/content dedup prevents re-emitting pre-compaction steps, so steps appended after the compaction point are still captured instead of being dropped until `total` overtakes the stale cursor. -**Deferred MCP tools** (if `tool_search.enabled`): `SubagentExecutor._build_initial_state` assembles deferral after policy filtering via the shared `assemble_deferred_tools` (fail-closed), appends the `tool_search` tool, injects the `` section into the subagent's `SystemMessage`, and threads the setup to `_create_agent`, which attaches `McpRoutingMiddleware` (when PR1 routing metadata matches deferred tools) before `DeferredToolFilterMiddleware` through `build_subagent_runtime_middlewares(...)`. Subagents thus withhold full MCP schemas until promotion, same as the lead agent; each task run gets a fresh `ThreadState` so promotion is isolated per run +**Deferred MCP tools** (if `tool_search.enabled`): `SubagentExecutor._build_initial_state` applies the subagent name allow/deny list and assembly-time authorization before calling the shared `assemble_deferred_tools`, appends the `tool_search` tool, injects the `` section into the subagent's `SystemMessage`, and threads the setup to `_create_agent`, which attaches `McpRoutingMiddleware` (when PR1 routing metadata matches deferred tools) before `DeferredToolFilterMiddleware` through `build_subagent_runtime_middlewares(...)`. Runtime skill policy is intentionally later and dynamic: `tool_search` may disclose/promote catalog metadata, but `SkillToolPolicyMiddleware` still removes or blocks any promoted business tool omitted by the active skill. Subagents thus withhold full MCP schemas until promotion, same as the lead agent; each task run gets a fresh `ThreadState` so promotion is isolated per run **Checkpointer isolation**: Subagent graphs are compiled with `checkpointer=False` to avoid inheriting the parent run's checkpointer, since subagents are one-shot and never resume. **Checkpoint lineage / stream isolation**: `_aexecute` deliberately omits checkpoint-coordinate keys (`thread_id`, `checkpoint_ns`, `checkpoint_id`, `checkpoint_map`) from the child `RunnableConfig`. LangGraph must inherit those coordinates from the copied parent ContextVar so the delegated graph retains a non-root subgraph namespace; explicitly re-supplying even the same parent `thread_id` starts a new root lineage on LangGraph 1.2.6+ and can route child AI/tool frames into the parent `messages` stream. DeerFlow business components still receive the parent `thread_id` through `runtime.context`, which is the preferred lookup path for sandbox, middleware, and attribution code. Regression coverage in `tests/test_subagent_executor.py::TestSubagentCheckpointLineage` keeps the invocation-contract assertion active on every supported version and version-gates the production-shaped parent-stream test to LangGraph 1.2.6+, where the leak exists. +**Isolated-loop callback boundary**: sync delegation from an active event loop and `execute_async()` copy the ambient ContextVars into the persistent subagent loop so checkpoint lineage, user identity, tracing context, tags, metadata, and LangGraph's namespaced message-stream handler survive. Before submission, `_copy_isolated_subagent_context()` copies the callback manager/list and removes only handlers marked `deerflow_loop_bound`; `RunJournal` carries that marker because it owns parent-loop tasks and a SQL store/pool. LangGraph merges inherited callbacks with the child run's explicit `SubagentTokenCollector`/tracing callbacks, so letting `RunJournal` cross loops causes duplicate accounting and `Future attached to a different loop` failures, while dropping the whole callback chain silently removes child token frames. Do not replace the boundary with a blank `Context`; the inherited checkpoint namespace and framework stream callback are required by the stream-isolation contract above. + ### Tool System (`packages/harness/deerflow/tools/`) `get_available_tools(groups, include_mcp, model_name, subagent_enabled)` assembles: @@ -703,7 +705,7 @@ E2B output sync records remote file versions and actual host file metadata in a - **Format**: Directory with `SKILL.md` (YAML frontmatter: name, description, license, allowed-tools, required-secrets) - **Loading**: `load_skills()` recursively scans public, per-user custom, global integration, and legacy custom locations for `SKILL.md`, parses metadata, and reads enabled state from extensions_config.json plus per-user skill state for non-public categories; that directory is a package boundary, so no nested `SKILL.md` is registered as a runtime skill. SkillScan has a deliberately narrower packaging rule: known eval fixtures are permitted as support data, while other nested `SKILL.md` files are reported as package defects. It parses runtime metadata and reads enabled state from extensions_config.json. - **External reload**: `POST /api/skills/reload` is an admin-only, process-local invalidation hook for trusted MinIO/NFS/CSI writes. `SkillStorage` instances do not cache a catalog — `load_skills()` scans on every call — so the route clears all `(app_config, user_id)` entries and the rendered prompt-section LRU, then waits up to the shared refresh timeout for the existing off-loop single-flight refresh. Each invalidation receives a generation-bound result handle; a successful scan atomically replaces the global enabled-skills cache, while a loader-level failure propagates to the HTTP waiter and preserves the last-known-good global cache. Per-user/config scans capture the refresh version and cannot repopulate shared caches if invalidation occurs while they are loading. A timed-out HTTP wait fails generically while the daemon refresh worker continues. Subsequent runs rescan after a successful reload; active runs keep their existing snapshot. Each Uvicorn worker/Kubernetes Pod must be targeted separately.

Memory updates now skip duplicate fact entries at apply time, so repeated preferences and context do not accumulate endlessly across sessions. diff --git a/backend/AGENTS.md b/backend/AGENTS.md index fa323801b..fc9f80458 100644 --- a/backend/AGENTS.md +++ b/backend/AGENTS.md @@ -229,7 +229,10 @@ Blocking-IO runtime gate (`tests/blocking_io/`): offloading the uploads-directory scan off the event loop); `test_uploads_router.py` (locks Gateway upload/list/delete endpoints offloading upload directory creation, staged writes, chmod/cleanup, - directory scans/deletes, and remote sandbox sync off the event loop); and + directory scans/deletes, and remote sandbox sync off the event loop); + `test_openviking_memory_backend.py` (locks the OpenViking backend's async + add/context/search entrypoints offloading synchronous HTTP and watermark + filesystem IO); and `test_workspace_changes_recorder.py` (locks the offload around the snapshot text cache lifecycle — roots resolution, `mkdtemp`, and the `shutil.rmtree` on both the capture-failure branch and `record_workspace_changes`' `finally`). @@ -847,6 +850,22 @@ The cached value is reused for both the blocking (`runs.wait`) and streaming (`_ **Workflow**: - `memory.mode: middleware` (default) keeps the passive path: `MemoryMiddleware` filters messages (user inputs + final AI responses), captures `user_id` via `resolve_runtime_user_id(runtime)`, queues conversation with the captured `user_id`, and the debounced background thread invokes the LLM to extract context updates and facts using the stored `user_id`. `DynamicContextMiddleware` passes the same resolved identity to the memory read path. On standalone Agent Server runs, server-owned auth identity is also resolved during lead-agent construction, normalized through `make_safe_user_id` for DeerFlow storage, and explicitly reused for custom-agent config/SOUL, user skills, skill policy, and prompt assembly; ordinary client `user_id` values cannot override `langgraph_auth_user_id`. On the embedded Gateway path, `inject_authenticated_user_context` removes client-supplied `langgraph_auth_user` / `langgraph_auth_user_id` from both RunnableConfig sections before graph construction, so those reserved fields cannot impersonate Agent Server auth. +- The optional `openviking` backend under + `packages/harness/deerflow/agents/memory/backends/openviking/` is a + remote-only HTTP adapter.

It does not implement DeerMem fact + CRUD/import/export and must not import the OpenViking embedded runtime. - `memory.mode: tool` skips `MemoryMiddleware` and registers `memory_search`, `memory_add`, `memory_update`, and `memory_delete` on the agent. The model decides when to search, add, update, or delete facts; this is opt-in/experimental and should not be described as better than middleware mode without eval evidence. - Both modes share `FileMemoryStorage`, per-user/per-agent isolation, prompt injection, manual CRUD primitives, and the updater backend. - Middleware mode queue debounces (30s default), batches updates, and commits global summaries plus the selected/default agent's fact delta through a user-level lock, optimistic user-memory revisions, per-fact revisions, and a recoverable target-file journal. Only explicitly marked point operations may rebase a stale shared revision, and only while every addressed fact still satisfies its original absent/revision precondition. Snapshot-derived clear/trim/consolidation operations instead reload the complete document and recompute their intent on a manifest conflict, with a bounded retry. Typed manifest/fact conflict subclasses keep that decision independent of exception text, and same-ID creates and stale same-fact writes fail. Scope-lock objects are weakly cached so inactive users do not grow a process-lifetime map. Cache validation does not scale with the fact-file count: its token combines the shared JSON's `(mtime_ns, size, revision)`, so the persisted revision invalidates stale caches even when a coarse-mtime filesystem reports identical metadata for same-size writes; direct out-of-band Markdown edits require `reload()`. Atomic replacement also syncs the parent directory on POSIX so the rename is durable. DeerMem translates private storage conflict/corruption exceptions to the backend-neutral MemoryManager contract; the Gateway maps them to HTTP 409 and a stable HTTP 500 response respectively. A normal default-manager read automatically migrates legacy facts from the global JSON into `__default__`; it also adopts the earlier implicit `lead-agent` fact bucket only when that directory has no custom-agent `config.yaml`, and rejects unexpected files instead of deleting them. The v1-to-v2 migration is one-way for the running application: operators must stop DeerFlow and snapshot the configured storage root before upgrade. Before any destructive v2 write, every migrated JSON source is durably retained as `{manifest_filename}.v1.bak`; a missing-write or mismatched existing backup aborts without modifying v1 data. Legacy per-agent JSON is deleted only after its non-empty summaries are safely adopted or confirmed identical; summary conflicts keep the source file and fail loudly. diff --git a/backend/packages/harness/deerflow/agents/memory/backends/README.md b/backend/packages/harness/deerflow/agents/memory/backends/README.md index 846008550..861762831 100644 --- a/backend/packages/harness/deerflow/agents/memory/backends/README.md +++ b/backend/packages/harness/deerflow/agents/memory/backends/README.md @@ -4,6 +4,7 @@ Each subfolder under `agents/memory/backends/` is a pluggable memory backend.

`agent_name` | Agent scope/tag/安全 URI 段 | 同一用户下的 Agent 专属范围 | +| `thread_id` | Session 稳定键的一部分 | 对话来源，不单独作为全局 Session ID | + +OpenViking 的 `user` 是强数据边界。每个请求必须显式带上当前 DeerFlow 用户身份，不能依赖 OpenViking 的 `default/default` 开发身份。 + +首版推荐使用 OpenViking `trusted` 认证模式，由 DeerFlow Gateway 向内部 OpenViking 服务传递： + +```text +X-OpenViking-Account: +X-OpenViking-User: +X-API-Key: +``` + +部署必须满足以下安全条件： + +- OpenViking 仅暴露在可信内网； +- 外部客户端不能绕过 DeerFlow 直接伪造 account/user header； +- DeerFlow 不接受客户端传入的 OpenViking account/user 值； +- user 值只来自 DeerFlow 已认证的 runtime user context； +- API key 只从服务端环境变量或 secrets provider 读取。 + +如后续选择 OpenViking `api_key` 模式，需要增加用户注册、用户 key 保存、轮换和吊销机制，不作为首版默认方案。 + +### 6.2 Agent 范围 + +DeerFlow 当前记忆作用域是： + +```text +(user_id, agent_name) +``` + +其中 `agent_name=None` 表示默认/共享桶。OpenViking 的用户记忆默认属于整个用户，因此必须额外表达 Agent 范围。 + +首版采用以下逻辑命名： + +```text +default Agent: __default__ +custom Agent: canonicalize(agent_name) +``` + +`canonicalize` 必须与 DeerFlow Agent 命名规则一致： + +- 转为小写； +- 只允许安全字符； +- 拒绝路径分隔符、`.`、`..` 和控制字符； +- 显式 Agent 不允许占用 `__default__`。 + +首版采用独立 OpenViking trusted-user 映射作为硬隔离边界： + +```text +openviking_user = "df_" + sha256(account + user_id + agent_scope)[:40] +``` + +这样不依赖 OpenViking 的实验性 Agent tag/URI 过滤语义，不同 DeerFlow +Agent 不可能通过一次普通用户级检索读到彼此的记忆。代价是同一 DeerFlow +用户的 profile/preferences 不会自动跨 Agent 共享；这是首版为强隔离选择的 +明确权衡。后续只有在 OpenViking 提供稳定、服务端强制的 Agent 过滤后，才 +考虑改为同一 OpenViking user 下的子范围，并且需要数据迁移方案。 + +### 6.3 Thread 与 Session + +Session ID 必须稳定、不可碰撞且不暴露原始标识。建议： + +```text +session_id = "df_" + base32( + sha256( + integration_namespace + + "\0" + account + + "\0" + user_id + + "\0" + canonical_agent_scope + + "\0" + thread_id + ) +) +``` + +要求： + +- 同一用户、Agent、线程始终映射到同一 Session； +- 任意一个作用域字段不同，Session ID 必须不同； +- 不直接把邮箱、用户名或 thread ID 放进 OpenViking Session ID； +- 算法一旦发布不得随意修改； +- `integration_namespace` 使用固定版本值，例如 `deerflow-openviking-v1`。 + +## 7. 写入流程 + +### 7.1 正常写入 + +现有 `MemoryMiddleware` 在 Agent 一轮完成后调用： + +```python +manager.add( + thread_id, + messages, + agent_name=..., + user_id=..., + trace_id=..., +) +``` + +OpenViking 后端处理流程： + +```text +接收 DeerFlow messages + -> 验证 user_id/thread_id + -> 计算 Agent scope 与 Session ID + -> 过滤框架内部消息 + -> 转换 user/assistant 文本消息 + -> 根据同步水位去除已提交到 Session 的消息 + -> 批量写入 OpenViking Session + -> 原子记录 submitted 水位 + -> commit Session + -> 推进 committed 水位并记录 commit task_id + -> 返回，不等待后台提取完成 +``` + +首版应使用 OpenViking 的批量消息接口；若锁定版本不支持批量接口，Client 可内部降级为逐条提交，但 Manager 接口保持批量语义。 + +### 7.2 消息过滤 + +首版只同步： + +- 用户的真实输入； +- Agent 最终可见的 assistant 回复。 + +首版不上传： + +- system prompt； +- middleware 内部提醒； +- `hide_from_ui` 且不含真实用户澄清内容的消息； +- tool call 的原始参数与完整输出； +- 二进制或 base64 payload； +- 仅用于流式拼接的中间 assistant chunk； +- subagent 内部推理和不可见消息。 + +消息过滤应由适配器自己的纯函数完成并单独测试。后端可以消费 DeerFlow 工厂传入的 `should_keep_hidden_message` hook，但不能直接导入 DeerFlow 的消息过滤内部模块。 + +### 7.3 幂等与同步水位 + +`add`、总结前的 `add_nowait`、请求重试和 Gateway 关闭 flush 可能看到重叠消息。仅依赖 OpenViking 去重不足以保证不会重复归档。 + +适配器需要保存每个 Session 的同步水位： + +```json +{ + "schema_version": 2, + "session_id": "df_...", + "submitted_message_ids": ["..."], + "committed_message_ids": ["..."], + "last_commit_task_id": "...", + "last_archive_uri": "viking://..." +} +``` + +水位文件使用工厂提供的 `backend_config.storage_path`，建议位置： + +```text +/openviking/sessions/.json +``` + +要求： + +- 原子写入； +- 不保存消息正文； +- 记录一个有界的近期 message ID 窗口，而不是无限增长； +- 批量添加成功后立即推进 `submitted_message_ids`，避免 commit 结果未知时 + 在下一轮重复添加消息； +- commit 结果未知时不自动重试该 commit；后续相同历史直接跳过，出现新消息时 + 只添加新消息，并由新的 commit 一并归档仍留在 Session 中的旧消息； +- commit 成功后将 `committed_message_ids` 推进到 submitted 水位并保存 + task/archive 元数据； +- 网络超时后需要区分“请求未到达”和“服务端可能已处理”； +- 若 OpenViking API 支持客户端 message ID，应始终发送 DeerFlow 的稳定 message ID。 + +这里的 submitted 水位只解决“批量添加已明确成功、随后 commit 失败”的确定性 +重复路径。如果批量添加在服务端成功、但客户端在收到响应或保存水位前中断， +没有服务端幂等键仍无法做到 exactly-once；多 Gateway 部署同样需要共享水位或 +OpenViking 原生幂等支持。 + +如果 DeerFlow 消息缺少稳定 ID，应基于角色、规范化内容和在本轮中的稳定位置生成适配器 ID，但该方案只作为兼容路径。 + +### 7.4 `add` 与 `add_nowait` + +OpenViking 自己在 commit 后异步提取，不需要复制 DeerMem 的 debounce queue。 + +- `add`：完成消息上传和 commit 接受确认后返回。 +- `add_nowait`：语义为“不要因 DeerFlow 总结丢失消息”，仍应立即完成上传和 commit 接受确认；它不是 fire-and-forget。 + +两者均不默认等待 OpenViking 后台 task 完成。 + +### 7.5 后台提取 + +OpenViking commit 通常先返回 `task_id`，摘要与长期记忆提取随后在后台执行。因此系统是最终一致的： + +```text +commit accepted != memory immediately searchable +``` + +首版策略： + +- 正常轮次不轮询 task； +- 保存最近一次 task ID 用于日志与诊断； +- task 失败不回滚 DeerFlow 主回复； +- `shutdown_flush` 只保证待上传消息已获得 commit 接受确认，不保证所有 OpenViking 提取任务完成； +- 集成测试可轮询 task 以验证完整闭环。 + +## 8. 检索与注入流程 + +### 8.1 `get_context` + +`get_context` 没有显式 query 参数，而且当前 prompt 调用点也不传 +`thread_id`。为保持主框架和共享接口不变，首版使用可配置的受控通用查询： + +```text +user profile preferences important entities events ongoing goals constraints and prior decisions +``` + +该值由 `retrieval.injection_query` 配置。请求固定限制到当前 hashed trusted +user 的 `viking://user/memories`，并设置 `context_type=memory`。显式 +`MemoryManager.search(query)` 仍使用调用者提供的语义查询。后续如果需要 +基于当前用户输入进行更精准的自动召回，应单独为共享接口设计可选 query +参数并更新所有 backend，不能通过线程局部变量隐式传递。 + +### 8.2 `search` + +映射到 OpenViking 检索接口： + +```text +query -> query +top_k -> node_limit +user_id -> OpenViking user identity +agent_name -> Agent scope filter +context_type -> memory +score_threshold -> backend_config.retrieval.score_threshold +``` + +返回值转换为 DeerFlow `memory_search` 可消费的字典： +

Split-origin or port-forwarded browser clients must opt in with `GATEWAY_CORS_ORIGINS` (comma-separated exact origins); Gateway `CORSMiddleware` and `CSRFMiddleware` both read that variable so browser CORS and auth-origin checks stay aligned. Those clients also need `CORS_EXPOSED_HEADERS` (`csrf_middleware.py`): run-creating routes return the run's id in `Content-Location`, which is not CORS-safelisted, so JS cannot read it unless it is exposed.

Same-origin nginx deployments never hit this because CORS does not apply. Browser auth sessions are owned by `app.gateway.auth.session_cookie`. Login accepts a `remember_me` form flag, but the Gateway never stores passwords. `SessionCookiePolicy` persists the `HttpOnly access_token` cookie only for HTTPS/trusted-forwarded HTTPS, direct-host localhost HTTP, or explicit operator opt-in for insecure persistence; public HTTP sandbox URLs degrade to session cookies. Session-creating handlers stamp the final `max_age` on `request.state`, and CSRF cookie creation mirrors that value so the double-submit cookie pair expires together, including explicit re-issue after password changes and OIDC callbacks. A small `HttpOnly` preference cookie preserves the user's remember choice across token re-issue paths. Logout clears all auth cookies and suppresses CSRF re-issue on the logout response. diff --git a/backend/app/gateway/app.py b/backend/app/gateway/app.py index 637bdbbe6..1c97050a7 100644 --- a/backend/app/gateway/app.py +++ b/backend/app/gateway/app.py @@ -10,7 +10,7 @@ from app.gateway.auth_disabled import warn_if_auth_disabled_enabled from app.gateway.auth_middleware import AuthMiddleware from app.gateway.browser_capability import ensure_browser_runtime_available from app.gateway.config import get_gateway_config -from app.gateway.csrf_middleware import CSRFMiddleware, get_configured_cors_origins +from app.gateway.csrf_middleware import CORS_EXPOSED_HEADERS, CSRFMiddleware, get_configured_cors_origins from app.gateway.deps import langgraph_runtime from app.gateway.routers import ( agents, @@ -539,7 +539,11 @@ This gateway provides runtime endpoints for agent runs plus custom endpoints for # CORS: the unified nginx endpoint is same-origin by default.

Each user has one `memory.json` containing only the project-independent `user` and `history` summaries; every fact is a canonical Markdown file below `agents/{agent_name}/facts/`. Existing lead-agent middleware, API, Settings, import/export, and embedded-client calls that omit `agent_name` resolve inside DeerMem to the reserved `__default__` bucket. That bucket is outside the valid custom-agent name grammar, so a real custom agent named `lead-agent` has a separate fact repository and deleting a custom agent cannot delete a memory-only directory without `config.yaml`. Public agent identifiers are case-insensitive and canonicalized to lowercase. Runtime/API readers still receive a compatibility `facts` array for the selected/default agent, so the frontend does not read agent facts from `memory.json`; structured Markdown `source` metadata is projected to the historical string field at the MemoryManager boundary. An unscoped Clear All first migrates facts from unread legacy per-agent JSON without adopting its soon-to-be-cleared summaries, then removes shared summaries and facts from every agent bucket while preserving agent configuration files, so a later read cannot resurrect skipped legacy facts; an explicitly agent-scoped clear removes only that agent's facts. On first normal read, old facts embedded in the user JSON are migrated automatically to `__default__`; facts written to the earlier implicit `lead-agent` bucket are also moved when that directory is not a real custom agent. Migration and normal writes notify the configured retrieval adapter only after durable storage locks are released. DeerMem uses a scope-aware SQLite FTS5/BM25 adapter by default, stores only rebuildable derived index data under `.retrieval/`, and rebuilds it in the background during Gateway startup or lazily on the first scoped search. A corrupt derived index is recreated automatically. Set `memory.backend_config.retrieval_adapter` to an empty string to disable it and use the local substring fallback. Chinese tokenization is optional; install the backend `memory-zh` extra (`uv sync --extra memory-zh`) for jieba-assisted sub-phrase search. Journaled writes, a shared user lock, and optimistic user-memory revisions prevent silent lost updates. +Memory injection follows the configured operation mode. In `middleware` mode, DeerMem injects the user-global summaries and the selected agent's facts. In `tool` mode, the automatic `` block contains only the global `user` and `history` summaries; agent facts are retrieved explicitly through `memory_search`, avoiding duplicate automatic and tool-returned fact context. Setting `memory.injection_enabled: false` still disables the entire block in either mode. + Single-fact repository operations are genuinely incremental: an upsert/delete reads, journals, writes, and re-indexes only the addressed fact files, and returns an explicit incomplete delta rather than a cache-dependent fake full document. Summary change sets merge the supplied `user`/`history` child keys over the persisted sections so a partial update cannot erase omitted siblings; full imports normalize both sections to the complete compatibility schema before applying replacement values. Manager/API compatibility methods materialize a fresh full document only when their public response contract requires one. Fact-level point operations use separate expected user-memory and fact revisions and may explicitly rebase when every addressed fact precondition still holds. Snapshot-derived operations such as scoped clear, capped create, consolidation, and trimming never replay stale delete/trim sets: a manifest conflict reloads the complete document and recomputes the operation, with a bounded retry. Fact paths use the first two hexadecimal characters of `SHA-256(fact_id)` so generated `fact_*` IDs distribute across shards. The cache token combines the shared JSON's nanosecond mtime, size, and persisted revision; this prevents coarse-mtime same-size writes from returning stale data without scanning fact files. Direct out-of-band Markdown edits require an explicit reload. Storage-specific conflicts and corruption are translated at the MemoryManager boundary; the Gateway returns conflict as HTTP 409 and a stable, non-sensitive corruption error as HTTP 500. Full-document `save()` remains a compatibility API and computes a diff before writing; malformed or missing `facts` can no longer silently erase an agent's Markdown files. Legacy migration preserves non-empty `user`/`history` before deleting an agent `memory.json`; conflicting summaries keep the legacy file and fail loudly instead of choosing a winner. Legacy facts in `memory.json` migrate automatically into the reserved `__default__` Markdown bucket on the user's first normal memory read. Operators who prefer to audit or complete the migration before serving traffic can run the optional idempotent CLI from `backend/`: diff --git a/backend/AGENTS.md b/backend/AGENTS.md index c0afa4d72..68d292d82 100644 --- a/backend/AGENTS.md +++ b/backend/AGENTS.md @@ -867,7 +867,7 @@ The cached value is reused for both the blocking (`runs.wait`) and streaming (`_ client operations within its timeout.

Injection is mode-aware: middleware mode injects global `user`/`history` summaries plus the selected agent's facts, while tool mode injects only the global summaries and leaves every agent fact behind `memory_search` to avoid duplicating automatically injected and retrieval-returned context. `memory.injection_enabled: false` suppresses the complete block in either mode. - Middleware mode queue debounces (30s default), batches updates, and commits global summaries plus the selected/default agent's fact delta through a user-level lock, optimistic user-memory revisions, per-fact revisions, and a recoverable target-file journal. Only explicitly marked point operations may rebase a stale shared revision, and only while every addressed fact still satisfies its original absent/revision precondition. Snapshot-derived clear/trim/consolidation operations instead reload the complete document and recompute their intent on a manifest conflict, with a bounded retry. Typed manifest/fact conflict subclasses keep that decision independent of exception text, and same-ID creates and stale same-fact writes fail. Scope-lock objects are weakly cached so inactive users do not grow a process-lifetime map. Cache validation does not scale with the fact-file count: its token combines the shared JSON's `(mtime_ns, size, revision)`, so the persisted revision invalidates stale caches even when a coarse-mtime filesystem reports identical metadata for same-size writes; direct out-of-band Markdown edits require `reload()`. Atomic replacement also syncs the parent directory on POSIX so the rename is durable. DeerMem translates private storage conflict/corruption exceptions to the backend-neutral MemoryManager contract; the Gateway maps them to HTTP 409 and a stable HTTP 500 response respectively. A normal default-manager read automatically migrates legacy facts from the global JSON into `__default__`; it also adopts the earlier implicit `lead-agent` fact bucket only when that directory has no custom-agent `config.yaml`, and rejects unexpected files instead of deleting them. The v1-to-v2 migration is one-way for the running application: operators must stop DeerFlow and snapshot the configured storage root before upgrade. Before any destructive v2 write, every migrated JSON source is durably retained as `{manifest_filename}.v1.bak`; a missing-write or mismatched existing backup aborts without modifying v1 data. Legacy per-agent JSON is deleted only after its non-empty summaries are safely adopted or confirmed identical; summary conflicts keep the source file and fail loudly. - **Proactive Markdown migration CLI**: from `backend/`, run `PYTHONPATH=. python scripts/migrate_memory_markdown.py --all-users --dry-run` to audit and omit `--dry-run` to migrate before serving traffic. Use repeated `--user-id` values when selecting exact original identities, especially standalone raw IDs containing `@` or other characters that are normalized in directory names; `--storage-path` selects a non-default DeerMem root. The CLI reuses `FileMemoryStorage.migrate`, is idempotent, continues across per-user failures, and exits non-zero if any user fails. It is optional because the first normal read still performs the same migration automatically. - `retrieval_adapter` owns indexing and retrieval. `fts5` is the DeerMem default and uses a persistent derived SQLite index under `.retrieval/`; an empty value disables the adapter and selects `substring_fallback`. File storage sends upsert/remove notifications for normal writes and both explicit and lazy migrations after releasing durable storage locks, then delegates search. Gateway startup schedules `DeerMem.warm_retrieval()` as a background full rebuild so readiness is not delayed, while a first search lazily rebuilds its exact scope until warm-up completes. Individual malformed facts are logged and skipped without triggering repeated full scans; only a fatal adapter rebuild failure keeps lazy retry enabled. During shutdown, the Gateway waits at most one second for this derived rebuild and leaves the full configured timeout to the canonical memory flush; if the rebuild is still active, its adapter remains open until process exit. Adapter failures mark the scope dirty and fall back to canonical substring search until rebuilding succeeds. `FileMemoryStorage` owns and closes the adapter so higher layers do not reach into private storage state. diff --git a/backend/packages/harness/deerflow/agents/lead_agent/prompt.py b/backend/packages/harness/deerflow/agents/lead_agent/prompt.py index 374e72632..7707e0896 100644 --- a/backend/packages/harness/deerflow/agents/lead_agent/prompt.py +++ b/backend/packages/harness/deerflow/agents/lead_agent/prompt.py @@ -1001,8 +1001,8 @@ def _build_memory_tool_section(*, app_config: AppConfig | None = None) -> str: return "" return """ -Memory is running in tool mode.

Across sessions, DeerFlow builds a persistent memory of your profile, preferences, and accumulated knowledge. The more you use it, the better it knows you — your writing style, your technical stack, your recurring workflows. Memory is stored locally and stays under your control. +DeerMem remains the default local backend. An opt-in `mem0` backend is also +available for the hosted mem0 Platform API or API-compatible self-hosted +servers. Its token-bearing `base_url` must use HTTPS by default; plaintext HTTP +requires an explicit local-development opt-in. See the +[mem0 backend guide](backend/packages/harness/deerflow/agents/memory/backends/mem0/README.md). + Memory updates now skip duplicate fact entries at apply time, so repeated preferences and context do not accumulate endlessly across sessions. File-backed memory now separates global user context from agent facts. Each user has one `memory.json` containing only the project-independent `user` and `history` summaries; every fact is a canonical Markdown file below `agents/{agent_name}/facts/`. Existing lead-agent middleware, API, Settings, import/export, and embedded-client calls that omit `agent_name` resolve inside DeerMem to the reserved `__default__` bucket. That bucket is outside the valid custom-agent name grammar, so a real custom agent named `lead-agent` has a separate fact repository and deleting a custom agent cannot delete a memory-only directory without `config.yaml`. Public agent identifiers are case-insensitive and canonicalized to lowercase. Runtime/API readers still receive a compatibility `facts` array for the selected/default agent, so the frontend does not read agent facts from `memory.json`; structured Markdown `source` metadata is projected to the historical string field at the MemoryManager boundary. An unscoped Clear All first migrates facts from unread legacy per-agent JSON without adopting its soon-to-be-cleared summaries, then removes shared summaries and facts from every agent bucket while preserving agent configuration files, so a later read cannot resurrect skipped legacy facts; an explicitly agent-scoped clear removes only that agent's facts. On first normal read, old facts embedded in the user JSON are migrated automatically to `__default__`; facts written to the earlier implicit `lead-agent` bucket are also moved when that directory is not a real custom agent. Migration and normal writes notify the configured retrieval adapter only after durable storage locks are released. DeerMem uses a scope-aware SQLite FTS5/BM25 adapter by default, stores only rebuildable derived index data under `.retrieval/`, and rebuilds it in the background during Gateway startup or lazily on the first scoped search. A corrupt derived index is recreated automatically. Set `memory.backend_config.retrieval_adapter` to an empty string to disable it and use the local substring fallback. Chinese tokenization is optional; install the backend `memory-zh` extra (`uv sync --extra memory-zh`) for jieba-assisted sub-phrase search. Journaled writes, a shared user lock, and optimistic user-memory revisions prevent silent lost updates. diff --git a/backend/AGENTS.md b/backend/AGENTS.md index 68d292d82..83720d2c3 100644 --- a/backend/AGENTS.md +++ b/backend/AGENTS.md @@ -248,6 +248,23 @@ Blocking-IO runtime gate (`tests/blocking_io/`): Boundary check (harness → app import firewall): - `tests/test_harness_boundary.py` — ensures `packages/harness/deerflow/` never imports from `app.*` +Memory backend async boundary: +- `MemoryMiddleware.aafter_agent` calls `MemoryManager.aadd`; network-backed + managers must override their `a*` methods to offload or use native async I/O. +- The mem0 backend requires an HTTPS `base_url` by default because requests + carry an API token.

The model decides when to search, add, update, or delete facts; this is opt-in/experimental and should not be described as better than middleware mode without eval evidence. - Both modes share `FileMemoryStorage`, per-user/per-agent isolation, manual CRUD primitives, and the updater backend. Injection is mode-aware: middleware mode injects global `user`/`history` summaries plus the selected agent's facts, while tool mode injects only the global summaries and leaves every agent fact behind `memory_search` to avoid duplicating automatically injected and retrieval-returned context. `memory.injection_enabled: false` suppresses the complete block in either mode. - Middleware mode queue debounces (30s default), batches updates, and commits global summaries plus the selected/default agent's fact delta through a user-level lock, optimistic user-memory revisions, per-fact revisions, and a recoverable target-file journal. Only explicitly marked point operations may rebase a stale shared revision, and only while every addressed fact still satisfies its original absent/revision precondition. Snapshot-derived clear/trim/consolidation operations instead reload the complete document and recompute their intent on a manifest conflict, with a bounded retry. Typed manifest/fact conflict subclasses keep that decision independent of exception text, and same-ID creates and stale same-fact writes fail. Scope-lock objects are weakly cached so inactive users do not grow a process-lifetime map. Cache validation does not scale with the fact-file count: its token combines the shared JSON's `(mtime_ns, size, revision)`, so the persisted revision invalidates stale caches even when a coarse-mtime filesystem reports identical metadata for same-size writes; direct out-of-band Markdown edits require `reload()`. Atomic replacement also syncs the parent directory on POSIX so the rename is durable. DeerMem translates private storage conflict/corruption exceptions to the backend-neutral MemoryManager contract; the Gateway maps them to HTTP 409 and a stable HTTP 500 response respectively. A normal default-manager read automatically migrates legacy facts from the global JSON into `__default__`; it also adopts the earlier implicit `lead-agent` fact bucket only when that directory has no custom-agent `config.yaml`, and rejects unexpected files instead of deleting them. The v1-to-v2 migration is one-way for the running application: operators must stop DeerFlow and snapshot the configured storage root before upgrade. Before any destructive v2 write, every migrated JSON source is durably retained as `{manifest_filename}.v1.bak`; a missing-write or mismatched existing backup aborts without modifying v1 data. Legacy per-agent JSON is deleted only after its non-empty summaries are safely adopted or confirmed identical; summary conflicts keep the source file and fail loudly. diff --git a/backend/packages/harness/deerflow/agents/memory/backends/openviking/client.py b/backend/packages/harness/deerflow/agents/memory/backends/openviking/client.py index 894959f66..46fdcfdbf 100644 --- a/backend/packages/harness/deerflow/agents/memory/backends/openviking/client.py +++ b/backend/packages/harness/deerflow/agents/memory/backends/openviking/client.py @@ -2,6 +2,7 @@ from __future__ import annotations +import random import time from typing import Any @@ -48,7 +49,16 @@ class OpenVikingHttpClient: write=config.write_timeout_seconds, pool=config.pool_timeout_seconds, ) -

The panel disappears while that state still reads open, leaving the divider draggable but inert and the panel's trigger needing two clicks to bring it back. Mirror a zero-width resize back into the owning state so a drag-collapse closes the panel the same way its trigger does, and keep recording non-zero widths there as the size to reopen at. --- frontend/AGENTS.md | 2 +- .../components/workspace/chats/chat-box.tsx | 29 +++++++++++++- .../tests/e2e/artifact-panel-resize.spec.ts | 39 +++++++++++++++++-- 3 files changed, 64 insertions(+), 6 deletions(-) diff --git a/frontend/AGENTS.md b/frontend/AGENTS.md index 1afb15965..af2c7266d 100644 --- a/frontend/AGENTS.md +++ b/frontend/AGENTS.md @@ -114,7 +114,7 @@ Edit-and-rerun is deliberately latest-turn-only. `core/messages/utils.ts::getLat - `src/components/workspace/messages/message-list.tsx` owns human-input card answered/latest/pending gating; entry pages only translate a submitted card response into `sendMessage` calls. - `src/components/workspace/browser-view/browser-view-panel.tsx` forwards each physical pointer click as one `click` input; do not also emit `down`/`up` for the same gesture because the remote Playwright click would run twice. - `src/core/threads/hooks.ts` owns pre-submit upload state and thread submission. -- `src/components/workspace/chats/chat-box.tsx` owns the desktop right-panel layout, and **all three** right panels (artifacts, sidecar, browser) share one `ResizablePanelGroup` — do not fork a non-resizable branch per panel kind, which is how the artifacts divider silently lost its drag handle (#4465).
