 **Dependency rule**: App imports deerflow, but deerflow never imports app. This boundary is enforced by `tests/test_harness_boundary.py` which runs in CI.
 
+### Report Collaboration (AgentScope, in progress)
+
+Independent of Workflow Studio and the existing roundtable. Plan: repo-root `docs/agentscope-多智能体报告协作工作台-后端实施计划.md`（`RC-BE-000`～`018` 已落地，下一票 `RC-BE-019`）。Spike baseline: `docs/AGENTSCOPE_BASELINE.md`.
+
+- **Config**: `config.yaml → report_collaboration` (`deerflow.config.report_collaboration_config.ReportCollaborationConfig`). Default **off** (`enabled` / `worker_enabled`).
+- **Contracts**: `app/report_collaboration/contracts/` — snake_case Pydantic models matching `frontend-web/src/report-collaboration/api/types.ts`. SSE envelope uses camelCase (`eventId` / `sessionId` / `runId`). `node_run_id` is always `${node_id}-attempt{attempt}`.
+- **Persistence**: `deerflow.persistence.report_collaboration` (`report_collaboration_*` tables, migrations `20260905_01` / `20260906_01` / `20260907_01`). SQL + memory stores; one active run per session via `active_dedupe_key`; command/message/run/version idempotency keys refuse cross-session reuse; event `seq` taken from the run row. Session delete removes children explicitly.
+- **Gateway**: `/api/report-collaboration` (`app/gateway/routers/report_collaboration.py`). `enabled=false` → 503. Plan/run writes enqueue durable jobs and return immediately. Pre-run `POST /sessions/{id}/messages` runs a rule-based `IntentRouterAgent` + `RequirementResolver` (`app/report_collaboration/requirement/`): writes a requirement revision and clarification messages, never auto-starts planning. `POST /sessions/{id}/plan-requests` then runs `PlanProposalService` (`app/report_collaboration/planning/`): catalog projection (no SOUL/keys) → selector → 2–3 strategy RoleDemand graphs → assembler binds catalog agents/tools/quality gates → validator (acyclic DAG, artifact types, allowlisted tools). Select and start-run stay independent commands. `POST /runs` freezes role models, report-structure template and run budget. Rewrite / apply / restore are live (`reporting/`). `GET /runs/{id}/stream` is a read-only durable SSE tail (`execution/live_hub.py`): persist then publish, replay + `after_seq` / `Last-Event-ID`, heartbeat comments, token-delta coalesce before seq assignment. Disconnect does **not** cancel the run. Lifespan mounts `ReportCollaborationDispatcher` only when `enabled` **and** `worker_enabled` are both true; default both false.
+- **Runtime**: AgentScope adapters live in `app/report_collaboration/agentscope_runtime/` (not the publishable harness). `ConversationReplica` maps AgentScope 2.0.5 events 1:1 onto collaboration SSE types; TeamSay is `HINT_BLOCK`. `DeerFlowChatModelAdapter` wraps `create_chat_model` (no second Provider config); role models are frozen onto node `agent_snapshot` at `POST /runs` and missing/incapable models fail with 422 before the run is created. Fallback is recorded on the snapshot plus a durable `heartbeat` audit event. Nodes complete only after a validated artifact (`app/report_collaboration/execution/completion.py`). `TaskLedger` (`execution/ledger.py`) owns ready waves, attempts and terminal node status; AgentScope / coordinator suggestions never pick the next node. A writer-bearing run is `completed` only after `ReportFinalizer` publishes a formal version. `WaveExecutor` + `QualityRoleKernel` (`execution/quality_roles.py`) remain for fixtures: Verifier marks stale/contested claims, Analyst/Writer only cite supported IDs, Reviewer `revise` replans only the target write node plus review. Production worker injects `AgentScopeMemberKernel` (`agentscope_runtime/member_kernel.py`) with DeerFlow tools and per-run budget. `QualityGate` (`execution/quality_gate.py`) is the claim-level gate: conflicts/missing units, unverified facts, coverage gaps, and unmapped review targets fail before `validated`; `ArtifactBoard.supersede_previous` hides old attempts from downstream. `ReportCollaborationLiveHub` (`execution/live_hub.py`) fans out persisted envelopes to SSE viewers; `PublishingReportCollaborationStore` sanitizes secrets/privacy/hidden reasoning without truncating visible tool results, and writes redaction + event audits. Dispatcher (`execution/dispatcher.py`) atomically claims queued/recovering/expired-lease runs, heartbeats via `renew_lease`, two-phase cancels (`cancel_requested` → `finalize_cancel`), and recovers orphans (`execution/recovery.py`): keep completed work, mark leftover in-flight `interrupted`/`superseded`, open a new `planned` attempt. Late artifacts after cancel/reclaim are `superseded` and must not change terminal run status. Tests drive `dispatch_once()`; do not rely on the background loop. Per-run budgets (`security/budget.py`) fail-closed; per-user active-run caps are enforced at `create_run`.
+- **Quality eval**: `app/report_collaboration/eval/` (`RC-BE-018`) — 20 annotated tasks (policy/market/enterprise/event/comparison ×4) with required angles, key facts, forbidden fabrications, templates and review rules. Deterministic scorer (no LLM judge) gates citation/angle/template/directed-mod; gold reports must pass, canned failures (including a roundtable-style essay) must fail and stay reproducible. Recommended runtime knobs live in `eval/thresholds.py` and match current `ReportCollaborationConfig` defaults (`worker_enabled` remains false). Tests: `tests/test_report_collaboration_eval.py`.
+- **Runtime intervention**: `app/report_collaboration/interventions/` owns run-time natural-language commands. `RuntimeIntentRouterAgent` uses explicit rules first and a tool-free coordinator-model fallback only for ambiguity; its Pydantic decision cannot dispatch or mutate anything. `ImpactAnalyzer` validates server-side node/agent ownership, resolves angle-specific lineage, and enforces confidence/cost/parallel-branch confirmation (`intent_confirmation_threshold`, default `0.8`). `RuntimeCommandService` mirrors the human message, emits frozen command events, CAS-claims accepted commands, and applies them only through `TaskLedger` safe points. Rework persists command overlays, supersedes affected attempts/artifacts, creates monotonic attempts, and prevents late output from entering downstream. Waiting-node answers resume only those nodes. `rerun_node` without a legal target does not expand to the whole graph; requirement patches apply only after rework succeeds; stuck `executing` commands are reclaimed on takeover or lease timeout; `command.cancelled` is a durable SSE event. In-run `POST /sessions/{id}/messages` returns 409 (`RUN_ACTIVE`). Formal rewrite candidates and version apply/restore live in `reporting/` (`RC-BE-015`).
+- **Dependency**: optional extra `report-collaboration` → `agentscope==2.0.5`. Do not add AgentScope to the harness `pyproject.toml`.

 ### Workflow Studio
 
 Coze Studio is canvas-only; ChatDev is reference-only. Plan + status per phase: `docs/WORKFLOW_STUDIO_BACKEND_DEV_ZH.md`; decisions: `docs/adr/0001-workflow-studio-runtime.md`; contracts: `docs/WORKFLOW_SCHEMA_V1_ZH.md` + `docs/WORKFLOW_SSE_V1_ZH.md` + `docs/WORKFLOW_OPENAPI_DRAFT_V1.yaml`. Master switch + all limits: `config.yaml` → `workflows` (`deerflow.config.workflow_config.WorkflowConfig`). `workflows.agent_recursion_limit` defaults to 250: LangGraph counts each model→tool research exchange as about two super-steps, so workflow agent/skill nodes must not fall back to a chat-sized 60-step limit. In the local Studio proxy, keep Rsbuild `server.compress: false`; dev gzip buffers small SSE frames and makes live planning/run output arrive only at completion despite the backend's `no-transform` / `X-Accel-Buffering: no` headers. The composer’s optional `modelName` must be validated against `AppConfig.models`: it selects the controller model and is copied only into newly generated candidate agent configs (or the projected direct-agent task), never injected into an already-confirmed proposal/run.

 - Candidate workflow graphs remain editable after they are loaded into the Coze-compatible canvas; the compatibility response explicitly marks the current owner as editable so node dragging is not mistaken for a read-only preview.
 - Workflow-agent SSE forwards provider `reasoning_content` as an inline `<think>…</think>` trace for the UI while keeping the executable node output limited to the visible answer text. Every native LangGraph `[AIMessage|ToolMessage, metadata]` frame is additionally persisted and sent as `node.message.data.messages` without projection or length cropping, so the Studio can replay DeerFlow's tool-result, search-result and `ask_clarification` cards exactly after reconnecting.
 
+### AgentScope report collaboration (in progress)
+
+The independent `/api/report-collaboration` workbench supports durable run-time intervention commands and immutable formal report versions. Its production worker now runs a real AgentScope 2.0.5 `Agent` per TaskLedger assignment; AgentScope owns the member ReAct/tool/structured-output loop, while TaskLedger alone owns DAG readiness, retries and completion. Ready nodes in one wave run concurrently up to `max_parallel_tasks`; cancellation and member exceptions close agent runs as terminal states, and lease recovery remains independent of in-memory AgentScope objects. Retrieval uses the deployment's configured DeerFlow `web_search`/`web_fetch` tools through the frozen role permission snapshot. Every visible AgentScope reply, TeamSay handoff, tool call and tool result is persisted immediately into the existing SSE/message protocol; hidden reasoning and system prompts are not exposed. A constrained intent agent classifies explicit answers, angle additions, re-search, re-analysis, node reruns, section rewrites, polishing, report questions, replanning, and cancellation. Server-side impact analysis validates node/agent ownership and computes the minimum downstream lineage; low-confidence, high-cost, or multi-branch changes require confirmation. Commands are CAS-claimed and applied at TaskLedger safe points, where old attempts and artifacts become `superseded` so late results cannot contaminate the revised report. Run creation freezes the selected `/api/report-structures` row and all server-enforced budgets. Per-user active-run limits and per-run model-call, retrieval, source-byte, token, cost, node-time, and total-time limits fail closed. User-visible event payloads are centrally redacted before durable persistence without size truncation; external source content is explicitly untrusted, and hidden reasoning/system prompts are never exposed. Append-only audits cover agent selection, tools, sources, user commands, confirmations, report versions, redactions, and budget failures; owner-scoped reads are available at `GET /runs/{id}/audits`. Temporary Markdown is emitted as `report.delta`; only a template/citation/coverage-clean report with an independent passing review is atomically persisted and emitted as `report.version.created` before the run becomes completed. Section rewrites are replacement candidates; apply and restore append a new head version and never destroy history. Configure `runtime_mode`, concurrency and limits under `report_collaboration`; both the feature and worker remain disabled by default. Install the `report-collaboration` project extra when enabling the worker.

+"""Permission adapter for the AgentScope report-collaboration runtime.
+
+Two responsibilities:
+
+1. Build an immutable ``MemberPermissionSnapshot`` per role and node attempt
+   so the rest of the runtime never asks the model for authority — every
+   tool call is decided against a frozen matrix.
+2. Decide whether a member is allowed to invoke a given tool with the given
+   arguments, with a structured ``PermissionDecision`` reason code. The
+   adapter must never trust client-provided authority. The decision is the
+   only thing the dispatcher / ``TaskLedger`` should consult.
+
+Default deny. The first version only allows the curated tool surface
+(``web_search`` / ``web_fetch`` / ``knowledge_search`` /
+``submit_artifact`` / ``team_say`` / ``request_clarification`` /
+``request_repair`` / ``propose_plan``). Anything that would expose the
+host filesystem, allow arbitrary code execution, free-form HTTP, database
+writes, or runtime package / skill installation is forbidden by role and
+by name; the matrix below is the only source of truth.
+
+Members never see system prompts, SOUL markdown, other members' private
+context, or hidden model reasoning. The adapter exposes only the
+allow-listed tools and the snapshot summary that is safe to surface in
+``session.snapshot``.
+
+Role × tool matrix:
+
+========================== ==========================================
+role                        allowed tools

+========================== ==========================================
+
+Notes:
+
+- ``submit_artifact`` is a single tool but the role determines which
+  ``artifact_type`` the call may submit. A writer cannot submit an
+  ``EvidenceBundle`` (that would be evidence laundering); a reviewer can
+  only submit a ``ReviewDecision``; a coordinator cannot submit any
+  artifact.
+- No role can promote unverified evidence to ``validated``. The
+  ``Verifier`` outputs ``VerificationResult``; only ``TaskLedger`` may
+  consume validated evidence downstream. ``submit_artifact`` here never
+  advances validation status — that is a QualityGate concern.
+- No role can install packages, run shell, open arbitrary URLs, or write
+  to the database directly. Those names are rejected even if a future
+  plan slips them into ``allowed_tools``.
+- Prompt-injection detection runs over external-content tool results. If
+  a ``web_*`` / ``knowledge_*`` result carries text that tries to elevate
+  permissions, the adapter downgrades the call to ``blocked_injection``
+  and emits a warning; the rest of the call body is dropped so it cannot
+  influence downstream reasoning or tool use.

+"""Tool adapter for the AgentScope report-collaboration runtime.
+
+Bridges AgentScope tool invocations to a server-controlled surface:
+
+- A ``ToolRegistry`` holds the curated tool surface for v1 (web search
+  / fetch, knowledge search, artifact board write, team_say,
+  clarification and repair requests, plan proposals). Anything else is
+  rejected before it can call into the agent process.
+- ``ToolAdapter.invoke`` runs every call through a frozen
+  ``MemberPermissionSnapshot``. Denials return a structured result and
+  emit an audit event; they never raise out of the adapter so the
+  conversation replica can keep mirroring the member's tool steps.
+- Tool results always carry a ``source_ids`` list (per the protocol
+  contract); the adapter never returns a content blob that lacks it.
+- External-content results (web / knowledge) are run through
+  ``scan_for_prompt_injection``; hostile text is dropped before it can
+  reach downstream prompts or tool calls.
+- Tool exceptions are caught and converted to a sanitized
+  ``ToolCallResult`` with a ``state="error"``. The user-visible message is
+  class name + sanitized description, never a stack trace; logs use the same
+  sanitized description so credentials cannot leak through exception text.
+
+The adapter is duck-typed for AgentScope: members do ``await
+adapter.invoke(tool_call_id=..., tool_name=..., args={...})`` and
+consume a ``ToolCallResult`` synchronously. Tests do not import
+AgentScope.

+# AgentScope 2.0 兼容性尖峰基线
+
+> 对应工单：`RC-BE-000`
+> 日期：2026-09-05
+> 候选版本：`agentscope==2.0.5`（PyPI 当前还有 `2.0.6` / `2.0.7.post1`；POC 通过前不把精确版本写入 lock）
+
+## 结论（当前）
+
+**条件 Go（安装 + 事件适配层） / 暂缓（真实模型评测与 uv.lock）**
+
+- 本机 Python 3.12.10 可安装 `agentscope==2.0.5`。`uv pip install` 未降级现有 FastAPI / Pydantic / OpenAI SDK；新增 25 个包（含 `dashscope`、`typer`、`opentelemetry-exporter-otlp`）。
+- 公开 API 已核对：`agentscope.event.EventType` 与本仓库 `ConversationReplica` 映射表一致；`agentscope.model.ChatModelBase` / `OpenAIChatModel` 存在。`RC-BE-007` 已用 `DeerFlowChatModelAdapter` 接 `AppConfig.models`。
+- 单元测试覆盖 dict 事件与真实 AgentScope 事件对象两条路径。
+- **尚未**把精确版本写入 `uv.lock`（按计划等纵向 POC 通过）。应用侧已声明可选 extra：`report-collaboration = ["agentscope==2.0.5"]`，不进入 harness 依赖。
+- **业务终态不依赖 AgentScope Python 对象**：节点完成仍由 `TaskLedger` + 已校验成果物决定。
+
+## 职责分界（已写入代码）
+
+| 组件 | 做什么 | 不做什么 |
+|---|---|---|
+| AgentScope Core | 单成员 `reply_stream`、工具、TeamSay（`HINT_BLOCK`） | 不决定下一节点、不宣告 completed |
+| `ConversationReplica` | 一对一镜像用户可见事件 | 不压缩为进度摘要 |
+| DeerFlow 合同 / 状态机 | 合法迁移、成果物完成条件 | 不把 assistant 短消息当完成 |
+
+## 事件映射（2.0.5）
+
+| AgentScope | DeerFlow SSE |

+| `THINKING_BLOCK_DELTA` | 默认丢弃；`emit_reasoning=true` 时才发公开 `reasoning_delta` |
+| `HINT_BLOCK` | `team_message.created` + `completed`（TeamSay 全文） |

+
+`node_run_id` 固定为 `${node_id}-attempt{attempt}`。并行成员共用 `phase_id`，各自 `agent_run_id`。

+## 尚未覆盖（后续工单）
+
+1. ~~`ChatModelBase` adapter 接 `AppConfig.models`（`RC-BE-007`）~~ **已完成**。
+2. ~~工具 / 权限 allowlist（`RC-BE-008`）~~ **已完成**。
+3. ~~TaskLedger 波次 + 受控运行器（`RC-BE-009`）~~ **已完成（脚本内核）**。真实成员内核与冒烟见 `RC-BE-017`；20 项标注评测与 20 次固定任务统计见 `RC-BE-018`。
+4. 离线 wheelhouse 更新（独立发布仓库，不提交本业务仓）。
+
+## Go 条件对照
+
+| 条件 | 状态 |
+|---|---|
+| 结构化输出达到 POC 阈值 | 未测（需真实模型，`RC-BE-009`） |
+| 取消在预算时间内生效 | 适配器可闭合 dangling tool；真实取消未测 |
+| AgentScope 异常不会把任务误标完成 | 合同层已禁止：无 validated artifact 不能 completed |
+| 业务恢复不依赖 AgentScope 对象 | 设计已冻结；`report_collaboration_*` 表与 store 已落地（`RC-BE-003`） |
+| Python 3.12 + `agentscope==2.0.5` 可安装 | **通过**（本机 venv，未写入 lock） |
