 | **Deep Research** (`/api/deep-research`) | Durable, user-owned research sessions/jobs with replayable SSE events and hidden-thread artifacts. `basic`/`quick` use the compact runner; `detailed` creates bounded subtopics, searches/writes sections concurrently, and assembles a report; `deep` recursively searches follow-up questions under a deterministic breadth/depth query budget. `multi_agent` is a LangGraph 1.x editor/researcher/writer/reviewer graph: its initial plan emits `awaiting_input`, the recorder stores the interrupt and releases the lease, and `POST /jobs/{id}/resume` rebuilds the graph from the persisted approved/revised plan. A bounded `custom_outline` is frozen into the session; headings/list entries deterministically supply the detailed and multi-agent plan, and the shared writer receives it only as a guarded content constraint. Completed reports support owner-scoped follow-up (`GET /sessions/{id}/messages`, `POST /sessions/{id}/chat`): context is only the current report, selected sources and recent messages; source-id citations are persisted, while `allow_new_research=true` is explicitly rejected. Owners may change that evidence set only after the job stops via `PATCH /sessions/{id}/sources/{source_id}`; this applies to future follow-ups rather than rewriting a completed report. Optional report illustrations are gated by `config.yaml -> deep_research.image_generation`: the Harness `OpenAICompatibleImageProvider` requires base64 output, the shared runner step writes only bounded `research-image-01..04.(png|jpg|webp)` artifacts and Markdown uses private `deep-research://` links. `GET /sessions/{id}/artifacts/{name}` checks session ownership before serving an image; an unavailable provider yields a warning but never fails the text report. Runners live in `packages/harness/deerflow/agents/deep_research/runners/`, may never import `app.*`, and use only the `AdapterBundle`. |
 | **Gateway auth** | Owner-scoped Deep Research routes await the platform's asynchronous `get_current_user` resolver before they read or write persistence, ensuring each session and job operation receives a concrete user ID.

One column = at most one square, so an item can never be "published twice". `''` = unassigned ? resolved to the default square at read/filter time.

+### Reference-mode Entry Switch
+
+The 参考文献/RAG citation-mode composer entry is system-controlled through
+`system_settings.json` → `citation_display.reference_mode_enabled` (default
+`false`). `GET /api/system-settings/citation-display` remains readable so the
+frontend can hide or show the entry consistently; `PUT` is admin-only and
+partially updates `reference_mode_enabled` and/or `cleanup_words`. The normal
+workspace input box, iframe chat toolbar, send context, right reference panel,
+and appearance settings all use this flag, while already locked citation
+threads and knowledge-base selections still render their references. Tests:

 ### Agent Module Tag Config (zzJC / zzXD 按类型聚合)
 
 Backs the zzJC / zzXD agent-chat left sidebar (「按类型聚合智能体 + 聊天记录」). An admin picks which agent **tags** belong to a module; the module's left sidebar then shows only agents under those tags (empty/unconfigured = show all visible agents). Stored in `system_settings.json` → `agent_modules` (`AgentModuleSettings`: `modules: {module_key → [tag_id, ...]}`); pure helpers `get_module_tag_ids` / `set_module_tag_ids` (de-dupe + strip). Endpoints (in `app/gateway/routers/system_settings.py`): `GET /api/system-settings/agent-modules/{key}` (readable by any user — the sidebar needs it to filter), `PUT /api/system-settings/agent-modules/{key}` (admin only, full replacement of the tag-id list). Module keys are frontend-defined (`AGENT_MODULES` in `components/workspace/agents/agent-module-sidebar.tsx`, keyed by the module's landing agent id: `6bf`→`zzjc`, `10d69…`→`zzxd`). Tests: `tests/test_agent_modules.py`. Frontend: `core/system-settings` (`useAgentModuleConfig`/`useUpdateAgentModuleConfig`), admin `AgentModuleSettingsDialog` (gear button in the agent-chat header).
