# 上下文压缩(对话摘要):长对话接近上下文上限时,把较早的消息总结成一段摘要,

Running the loop inline for a large batch outlives the nginx gateway timeout (504), which the frontend's `parseResponse` surfaces as a generic "Request failed"; `background=false` keeps the blocking path (full per-thread `created/skipped/failed` tally) for small batches/scripts. Shared loop: `_run_batch_ingest`. **Optional model selection**: both ingest endpoints accept `model_name` (overrides `knowledge.extract_model_name` for that capture; threaded through `KnowledgeService.capture_thread` ? `extract_thread_llm_multi`). **Model-error surfacing**: when the chosen model produces nothing usable (timeout / API error / non-JSON) capture still **falls back to rule-based extraction and lands a draft** (`llm_fallback:true`); the single-thread (non-background) response and the batch response (`llm_fallback` count) carry this so the UI tells the user "???????". The "??????" chat button stays background/fire-and-forget (passes `model_name`, no per-save error toast); the batch-import dialog is synchronous and shows the fallback count. `POST /ingest/file` - **import an uploaded file** (multipart: `file` + optional `title`/`tags`/`status`/`model_name`) into wiki note(s): the file is converted to Markdown (md/txt read directly, pdf/word/ppt/excel via `convert_file_to_markdown`), distilled by the same wiki-capture LLM pipeline as thread capture (`source_type="file"`), and falls back to a verbatim **draft** note when the model returns nothing usable (`llm_fallback:true`); `POST /ingest/search` - sediment search/tool results as a reference note; `POST /notes` - manual note; `GET /notes` (keyword/tag/source_type/status + pagination); `GET/PUT/DELETE /notes/{id}` (DELETE is soft = archive, `?hard=true` removes the vault file); `POST /search` - `mode=keyword\|vector\|hybrid` (vector?keyword fallback when no embedding endpoint); `GET /notes/{id}/versions` - edit history; `GET /duplicates` + `POST /merge` - dedup; `POST /reindex` - rebuild vector index; `GET /graph` - product graph data (notes + entities, graph-blacklist filtered); `GET/POST /graph/blacklist` + `DELETE /graph/blacklist/{id}` - graph node blacklist (labels = entity names / note titles, case-insensitive match; blacklisted nodes and their edges are dropped from `/graph` and the wiki-export artifacts; table `knowledge_graph_blacklist`, auto-created); `POST /export/graph` + `GET /export/files/{graph.json\|graph.html\|graph.graphml\|cypher.txt}` - obsidian-wiki `wiki-export` artifacts (self-contained `graph.html` for iframe); `POST /resolve` `{targets:[?]}` + `GET /notes/{id}/wikilinks` - resolve `[[wikilink]]` targets to a note id / vault page / missing (powers clickable wikilinks); `GET /vault-page?path=` - read a raw vault meta/hub Markdown page (no DB note). `GET/POST /folders` + `PUT/DELETE /folders/{id}` - user-managed directories (notes carry a `folder` path; `GET /notes?folder=` filters a dir + sub-dirs); `GET/POST /extract-templates` + `GET/PUT/DELETE /extract-templates/{id}` - editable extraction-prompt templates (thread/document ingest accept `template_id`; capture/PUT-note accept `folder`).

Positive (taskId→creator) results are cached process-wide (immutable mapping); any failure / memory-mode store / missing row falls back to the current login. **Caveat**: files a *non-creator* wrote into a shared thread before this fix stay orphaned under that writer's dir (no data loss); all new writes consolidate under the creator. **Extended to 圆桌会商 system threads** (`metadata.thread_type == "roundtable"` — Step 2 seats/coordinator + Step 3 report/summary/dashboard/structure, created by `multi_agent.py` with `_ROUNDTABLE_THREAD_METADATA`): their Step2/Step3 sandbox artifacts (md/流程图/报告) must stay viewable when a历史草稿 is reopened or a taskId会商 draft is opened by another account, so `thread_paths._is_creator_shared_thread(metadata)` treats both `taskId` **and** `thread_type=="roundtable"` as creator-shared, and `ThreadMetaRepository.check_access` (the artifacts router's `owner_check`) bypasses the owner filter for both — roundtable thread ids are only surfaced inside the owner's draft, so this does not let unrelated accounts *discover* others' 会商 files. Tests: `tests/test_thread_paths_owner.py`, `tests/test_thread_paths_roundtable.py`.
- **`{user_id}` for path resolution = `resolve_path_user_id(thread_id)`, using the persisted creator for every tracked thread.** The route's regular owner check still authorizes access first; creator resolution only selects the stable physical directory (`threads_meta.user_id`) and avoids a lost request context falling back to `users/default`. This also preserves cross-account task-deeplink conversations (rwfx/3qfx/xdfx) and roundtable system threads. Positive creator mappings are cached process-wide and DB/memory/missing-row failures fall back to the current login. It is wired at the thread-path consumers including `ThreadDataMiddleware.before_agent`, `present_file_tool`, uploads, artifact serving, and embedded `client.get_artifact`. **Rewrite-history recovery is metadata-only and job-owner scoped** (`list_by_session(..., user_id=current_user)`), so its GET/list endpoints intentionally skip redundant thread-owner checks and return an empty history instead of a history-only 404; the start/commit endpoints retain strict thread write authorization. Tests: `tests/test_thread_paths_owner.py`, `tests/test_thread_paths_roundtable.py`.
- **Durable document-rewrite commit:** `document_rewrite_pipeline.atomic_write_text` writes through a deliberately short sibling temporary filename so long Windows artifact paths stay below the path-length limit, and guarantees the target `outputs` parent exists. If the sandbox recreates that directory in the narrow commit window, it repairs the directory and retries; the original file is otherwise only changed through `os.replace`.
- **Deep Research structural regeneration:** `POST /api/deep-research/sessions/{id}/report-variants` creates a distinct completed session from the source report and its selected evidence. It rebases both saved `[来源：source_id]` and legacy streamed `[[source:source_id]]` markers to cloned ids, and removes inherited markers with no selected clone. The frontend uses this endpoint only for “选择结构再生成”, then queues the durable writer with `operation=generate`; generation receives the confirmed outline and complete selected evidence set but never receives the inherited report as text to edit. The new report's completed card can subsequently start a separate in-place `AI 全文改写`. Requirement plans are deterministic and operation-specific, model reasoning is forwarded as live SSE before the first Markdown token, and generation prompts emit display-ready `[来源：id]` citations. Citation validation repairs only a unique near-complete `drs_src_*` prefix (provider-truncated suffix) and still rejects genuinely unknown ids. The report-only stream requests 8192 output tokens (except Codex Responses models, which reject token-limit kwargs) and rejects a malformed trailing citation instead of committing a provider-truncated report. Never restore the former second planning-model call unless its latency and streaming contract are redesigned together.

Health probes are always unauthenticated, even when API authentication is enabled: `GET|HEAD /health`, `/api/health`, and `/api/langgraph/health` all return the Gateway health status without requiring a cookie or bearer token.
Browser authentication is page-context aware. Normal application tabs share the account stored in `localStorage`; `embed=1` and `isolate=1` pages intentionally keep their own account in per-tab `sessionStorage`. Frontend API calls send that selected account as an explicit `Authorization: Bearer` token, and both Gateway and LangGraph authentication give the header priority over the origin-wide session cookie. This prevents a login in another tab or iframe from making the current page query threads as the wrong account. Reissuing a token for the same normalized username is not treated as an account switch; a real switch clears account-scoped frontend state, opens a fresh chat when necessary, and does not reload the whole browser page. Bare username login is domain-agnostic and deterministically reuses the oldest matching account if legacy synthetic email domains coexist; an explicitly supplied email still selects that exact address.

## Core Components
### Administrator fixed questions
Administrators can manage exact-match question/answer pairs from the frontend
「问题配置」 page. Each pair has its own enabled switch and configurable fixed-answer
streaming speed (`1–1000 token/s`, default `100 token/s`). For an enabled pair,
a plain-text external chat turn whose text exactly equals the configured
question is answered by a local streaming graph and never sent to a model
provider. The normal LangGraph SSE protocol and checkpoint persistence are
preserved, so the fixed response appears in live chat and conversation history.
Multimodal/file turns, AI Writing/Canvas flows, and internal orchestration child
runs bypass this lookup and continue through their normal model pipeline.
The admin-only configuration API is `GET|PUT /api/fixed-questions`; `PUT`
atomically replaces the full set. Rows are stored in `fixed_questions` (Alembic
revisions `20260821_01` and `20260821_02`) and are looked up with a SHA-256 index plus an exact
original-text comparison.

- **Conditional WeKnora LLMWiki**: a non-empty `llmwiki.weknora.api_base_url` enables the DeerFlow-native WeKnora BFF and UI; an empty address preserves the existing LLMWiki page. WeKnora remains independently deployed and owns its database, Redis, storage, parsers and models. DeerFlow keeps only the API/admin addresses, user/publication mappings, agent knowledge-base bindings and per-conversation selections; it stores and sends no WeKnora credential, so the endpoint must be restricted to a trusted network and allow DeerFlow traffic. Owners publish directly to the public LLMWiki without an approval queue for ordinary bases; the system-owned conversation-deposit base is always published, shared by all users, excluded from My Knowledge, immutable through user/admin detail operations, and recognized by both its reserved name and `system` owner. An existing same-name remote mapping is adopted in place as the system deposit so its mapping id and document links stay valid. Its user-facing knowledge-base description and generated document metadata use the `cmzs` brand; list/detail reads synchronize stale remote descriptions, while conversation-deposit search results, source previews and embedded-detail JSON rewrite legacy brand text to `cmzs`. Deposit requests must reference a thread accessible to the current account. Personal knowledge-base lists are scoped to the current DeerFlow account even for admins, while frontend LLMWiki query caches also include the active account id so switching accounts cannot reuse another account's list/detail data. Admins remain the only role that sees the WeKnora connection-config tab. Knowledge cards open a dedicated WeKnora-style detail route: Wiki-enabled bases default to Wiki, then documents and graph; standard bases hide Wiki and default to documents. Writable ordinary knowledge-base details expose a native multi-file upload action that submits files sequentially and reports aggregate success/failure; read-only public bases and the system deposit base do not. It supports file/URL/manual-Markdown imports, Wiki page browsing, document preview, real parsed chunks and Wiki graph nodes/edges. New chats use a compact WeKnora-style searchable/grouped multi-select inside the composer, while agent create/edit pages bind spaces through an inline panel. A single proxy service identity means DeerFlow users are isolated logically while their WeKnora entities share that identity's workspace. The read-only `llmwiki_search` tool reauthorizes the current DeerFlow user on every call and renders credential-free source previews; source previews prefer cleaned Wiki/LLMWiki text when a retrieved chunk maps to a Wiki page, with raw chunks as the fallback. The detail page first creates a signed iframe session through the normal DeerFlow API auth path, then points the iframe directly at the proxied WeKnora `/platform/...` route using the signed `deerflow_weknora_embed` cookie; global auth/CSRF bypass is limited to those signed iframe proxy requests, and HTTPS cookie attributes honor `X-Forwarded-Proto` behind reverse proxies. The iframe proxy keeps WeKnora's root-relative `/platform`, `/assets`, `/locales`, and `/api/v1/*` paths, but is registered last through `llmwiki.proxy_router` so it cannot intercept first-party Gateway APIs such as `POST /api/v1/auth/login/username`.

- **Embedded WeKnora knowledge-base switching**: the original breadcrumb picker works inside the iframe, but lists only the signed-in user's own and published knowledge bases. Every switch is reauthorized through DeerFlow and receives a fresh short-lived iframe session, so it never exposes the upstream service-admin knowledge-base list.
- **Prefixed WeKnora deployment**: the frontend may be published under a separate prefix such as `/magentweb`, while embedded WeKnora detail traffic is served by the Gateway under `/deerflow`. The Gateway rewrites HTML root assets, WeKnora API URLs, redirects, and Vite dynamic dependency maps so page assets stay under `/deerflow`; the prefixed proxy routes must be registered before the unprefixed fallback. The signed embed cookie covers `/deerflow`, and auth/CSRF recognition includes all supported static directories.

only applies to sessions with a `running` or `awaiting_input` durable job.
Whole-report rewrite builds its requirement plan locally from the selected

one model stream for the actual Markdown writer. This avoids making users wait
for a separate model-thinking/planning pass before sandbox output begins.
`POST /api/deep-research/sessions/{id}/report-variants` is the structural
regeneration boundary: it copies the completed report and selected evidence
into a new session (including both saved `[来源：id]` and legacy streamed
`[[source:id]]` citation markers remapped to the cloned ids). The following
durable writer is explicitly queued with `operation=generate`: it does not send
the inherited report to the model as text to edit, and instead writes a fresh
report from the complete selected evidence set plus the newly confirmed
outline. Model reasoning remains a live SSE event before the first Markdown
token. New output uses display-ready `[来源：id]` citations; validation repairs
only unique near-complete `drs_src_*` ids (for example a provider-truncated
suffix) and still rejects genuinely unknown evidence ids.
The report-only model stream requests an 8192-token completion budget so a
normal multi-section report and its reference list do not stop at the common
4096-token provider default; malformed trailing citation syntax is rejected
rather than committed as a partial document.

## Document rewrite fallback
Whole-document rewrite commits the artifact/report before it attempts to store
the optional reversible before-image. If that version-snapshot write fails, the
rewritten content remains available and Gateway logs the exception; it never
restores the original solely because undo history is unavailable. The durable
result marks `versionSnapshotFailed`, allowing the sandbox to enable its normal
manual-save action without showing the user an error notification.
The optional rewrite-history hydration endpoints scope results to the
authenticated job owner. They deliberately return an empty list rather than
performing a second thread-owner check, so a legacy guest/SSO display alias
cannot make an otherwise usable sandbox report fail with a history-only 404.
Artifact and rewrite path resolution uses the persisted thread creator's
directory when metadata exists, after the route's normal ownership check. This
prevents a missing request context from incorrectly looking under
`users/default` and returning 404 for an existing sandbox file.
The final rewrite commit uses a deliberately short sibling temporary filename,
which keeps long Windows artifact paths below the path-length limit. It also
recreates a missing `outputs` parent before retrying, so transient
sandbox-directory recreation cannot discard a completed rewrite.

收到研究课题后，按以下顺序工作，并把过程自然地讲给用户听：
1. **理解课题**：先用一小段话说明你对课题的理解、打算从哪些方面收集信息（背景、现状、数据、案例、趋势、争议点等）。这段话直接输出，不要调用工具。
2. **拆分检索词**：把课题拆成若干具体的检索词，覆盖不同方面、避免重复。
2. **拆分检索词**：把课题拆成若干具体的检索词，覆盖不同方面、避免重复。**例外**：若用户消息含有 `<retrieval-directions>` 块，则**按这些方向来拆分检索词**——每个方向拆成若干具体、可检索的词（专名、时间、地点、同义/中英对照等），**不要把方向名称本身当检索词**（方向标签往往搜不到结果）；不要扩展到未列出的方向。某个检索词没有结果时换更具体或更短的词再试。
3. **按顺序检索**：**一次只检索一个检索词**，检索完看结果，再决定下一个。这样用户能看清每个检索词换回了什么材料。
4. **需要时用技能**：如果某个检索词更适合知识库或某个技能，先读取技能说明（read_file 技能的 SKILL.md），再按说明调用。
4. **需要时用技能**：如果某个检索词更适合知识库或某个技能，先读取技能说明（read_file 技能的 SKILL.md），再按说明调用。**例外**：若用户消息含有 `<retrieval-skills>` 块，则必须按其中列出的技能检索：先 read_file 每个技能的 SKILL.md，再按其说明调用；不要改用未列出的技能，也不要自行改成纯 web_search（除非技能说明要求联网）。
5. **交叉验证与补漏**：发现关键信息缺来源、或多个来源说法矛盾时，补一轮针对性检索。
6. **输出收集小结**：检索完成后，输出一段「收集小结」，包含：
- 覆盖了哪些方面、共收集到多少条材料；

# 外部系统智能体会话与消息 API
Base URL 为 Gateway 的 `/api`（部署若由反向代理配置了前缀，以网关实际暴露地址为准）。所有接口沿用现有 `Authorization: Bearer <token>` 鉴权；无效或过期 token 返回 `401`。
## 会话隔离键
外部系统创建和检索会话时使用以下**精确拼写**的 metadata 键，三个值均为字符串：
| 键 | 类型 | 约定 |
| --- | --- | --- |
| `agent_id` | string | 智能体 ID |
| `task_id` | string | 任务 ID；数字也必须传字符串 |
| `chat_type` | string | 页面决定的隔离标识；UTF-8 原样保存、原样比较、原样返回，不做 trim、大小写转换或枚举校验 |
`chat_type` 的可用长度大于 64 字符（metadata 存为 JSON 对象）。存量未带 `chat_type` 的线程保持原有行为；只有检索条件中显式提供 `chat_type` 时才会要求该字段精确相等。
## 1. 创建与按隔离键查找会话
### `POST /api/threads`
| 参数 | 位置 | 必填 | 类型 | 说明 |
| --- | --- | --- | --- | --- |
| `metadata.agent_id` | body | 是（外部集成约定） | string | 智能体 ID |
| `metadata.task_id` | body | 是（外部集成约定） | string | 任务 ID |
| `metadata.chat_type` | body | 是（新会话） | string | 页面隔离键 |
| `thread_id` | body | 否 | string | 不传则服务端生成 UUID |
| `assistant_id` | body | 否 | string | 现有兼容字段 |
```json
{
"metadata": {
"agent_id": "c353429a73e146ae9e6926054b2d155a",
"task_id": "108",
"chat_type": "测试分析"
}
}
```
```json
{
"thread_id": "c7cefe92-84f8-4f31-aed0-a16f7b151cc2",
"status": "idle",
"created_at": "2026-08-22T10:00:00+00:00",
"updated_at": "2026-08-22T10:00:00+00:00",
"metadata": {
"agent_id": "c353429a73e146ae9e6926054b2d155a",
"task_id": "108",
"chat_type": "测试分析"
},
"values": {},
"interrupts": {}
}
```
### `POST /api/threads/search`
| 参数 | 位置 | 必填 | 类型 | 默认／范围 | 说明 |
| --- | --- | --- | --- | --- | --- |
| `metadata` | body | 否 | object | `{}` | 所有提供的键均做精确 AND 匹配 |
| `limit` | body | 否 | integer | `100`，`1..1000` | 最多返回条数 |
| `offset` | body | 否 | integer | `0`，`>=0` | 结果偏移量 |
```json
{
"metadata": {
"agent_id": "c353429a73e146ae9e6926054b2d155a",
"task_id": "108",
"chat_type": "测试分析"
},
"limit": 1
}
```
```json
[
{
"thread_id": "c7cefe92-84f8-4f31-aed0-a16f7b151cc2",
"status": "idle",
"created_at": "2026-08-22T10:00:00+00:00",
"updated_at": "2026-08-22T10:05:10+00:00",
"metadata": {
"agent_id": "c353429a73e146ae9e6926054b2d155a",
"task_id": "108",
"chat_type": "测试分析"
},
"values": {},
"interrupts": {}
}
]
```
匹配结果按 `updated_at` **倒序**，并以 `thread_id` 倒序作同时间稳定排序。响应返回完整 metadata。
## 2. 读取会话消息
### `GET /api/threads/{thread_id}/messages`
| 参数 | 位置 | 必填 | 类型 | 默认／范围 | 说明 |
| --- | --- | --- | --- | --- | --- |
| `thread_id` | path | 是 | string | - | 会话 ID |
| `limit` | query | 否 | integer | `200`，`1..1000` | 返回消息数 |
| `offset` | query | 否 | integer | `0`，`>=0` | 从最早消息起跳过的消息数 |
消息按照会话内实际写入顺序（时间正序）返回，`total` 为分页前总条数。接口读取最新 LangGraph checkpoint，并使用与 `state`／流式消息相同的序列化路径：不按展示用途裁剪 `additional_kwargs`、`tool_calls`、隐藏消息或供应商扩展字段。
```json
{
"total": 2,
"messages": [
{
"type": "human",
"id": "msg-1",
"content": [{"type": "text", "text": "隐藏上下文"}],
"additional_kwargs": {"hide_from_ui": true, "client_ts": "2026-08-22T18:00:00+08:00"}
},
{
"type": "ai",
"id": "msg-2",
"content": "这是回答",
"tool_calls": [{"name": "lookup", "args": {"keyword": "测试"}, "id": "call-1"}],
"additional_kwargs": {"reasoning_content": "完整思考字段", "hide_from_ui": false}
}
]
}
```
`hide_from_ui` 位于消息的 `additional_kwargs.hide_from_ui`（若该消息实际带有此字段）。`tool_calls[].args` 不被转换：LangChain 已解析的标准 `tool_calls` 通常是 JSON 对象；供应商原始工具调用若保留在 `additional_kwargs`，其原始字符串／对象形态也保持不变。
## 3. 删除一轮对话
### `DELETE /api/threads/{thread_id}/messages/{message_id}`
`message_id` 应取自消息列表中用户消息（`type: "human"`）的 `id`。删除该问题及其后的 AI、工具、中间消息，直到下一条用户消息之前；若传入的是非用户消息 ID，仅删除该消息。删除会写入新的 checkpoint，随后读取消息列表即可获得已删除后的结果。
成功示例：
```json
{
"ok": true,
"deleted_ids": ["question-1", "answer-1", "tool-1"],
"remaining": 2
}
```
## 4. 删除整个会话
### `DELETE /api/threads/{thread_id}`
清理该线程的 checkpoint（含消息）、线程 metadata 与该线程目录下的上传文件／工作区／生成产物。会话检索不再返回该线程。
```json
{"success": true, "message": "Deleted local thread data for c7cefe92-84f8-4f31-aed0-a16f7b151cc2"}
```
## HTTP 错误
| 状态码 | 触发条件 | 响应体示例 |
| --- | --- | --- |
| 401 | 缺少、无效或过期的 Bearer token | `{"detail":"Authentication required"}` |
| 403 | token 没有对应线程权限 | `{"detail":"Permission denied: threads:read"}` |
| 404 | 线程不存在、无权访问、或 `message_id` 不存在 | `{"detail":"Thread xxx not found"}` |
| 409 | 上述接口当前不使用 409 | 不适用 |
| 422 | 分页参数越界，或请求体字段类型不合法 | FastAPI 标准校验错误对象 |
| 429 | 上述接口本身未配置限流；如部署侧网关限流，由部署网关返回其配置的响应体 | 不适用 |
| 500 | checkpoint 或持久化读取／写入失败 | `{"detail":"Failed to get thread messages"}` 等 |
时间字段 `created_at` 与 `updated_at` 使用 ISO 8601、带 UTC 偏移量；不是毫秒时间戳。
## 兼容性与生命周期
- 既有 `/threads`、`/runs/stream`、`/models` 调用不改动；仅新增消息查询，并修复单轮删除的 checkpoint 持久化。
- 普通线程未配置通用自动过期策略、单任务会话数上限或 `chat_type` 枚举；保留至调用方删除或运维侧另行清理。AI 写作等独立业务的专用清理策略不适用于本接口。
- 外部系统的联调 task、预置线程、发布窗口和联系人属于部署运维信息，不在代码中硬编码；请在目标测试环境创建后补入联调单。
- Swagger 地址为 `<Gateway Base URL>/docs`；OpenAPI JSON 为 `<Gateway Base URL>/openapi.json`。

"""Cap deliverable tools for position-roundtable seats.
Weak models (especially after a first successful Markdown write) often call
``write_file`` again with another copy of the same report, or call
``present_files`` twice for the same path, and loop until the recursion
limit kills the run. The UI then shows two identical "Successfully
presented files" cards even though only one file exists on disk.
When the run context carries ``position_artifact_cap`` (set by the position-
roundtable UI for ordinary seats and the summary agent — **not** for
action-plan, which must emit report + JSON), this middleware:
1. Truncates excess outputs ``write_file`` **and** ``present_files`` calls in
a single model response (keeps only the first *N* of each), including
raw provider metadata.
2. Rejects further such calls once *N* successful *or* earlier in-batch
calls already exist in the current user turn (so parallel tool calls
cannot race past the cap).
3. Ends the turn when the only remaining calls were excess writes/presents.
4. Injects a brief hidden reminder before the next model call:
- write done, not yet presented → present once, then wrap up;
- write **and** present already done → wrap up, do **not** present again.

"""ORM model for deep-research report structures (报告结构 / 工作流配置).
Global / shared — every account sees the same structure cards in the deep
research workbench's 工作流配置 dialog. Each row is one reusable report
structure the user can pick to fill ``custom_outline``:
- ``title`` — 标题, the card's primary label and the list's 标题筛选 target.
- ``name`` — 名称, a secondary display label.
- ``content`` — 接口内容, the Markdown outline text applied to the research
config's ``custom_outline`` when the card is selected.
- ``structure_mode`` — 结构约束: ``fixed`` (固定大纲) reproduces the stored
headings and hierarchy; ``adaptive`` (弹性大纲) keeps the current
material-driven layout. Existing rows default to ``adaptive``.
- ``retrieval_directions`` — 检索方向, an optional list of search facets.
Empty / unset keeps today's collector query-planning; a non-empty list
tells material collection to **split retrievable terms along those
directions** (not to search the labels themselves).
- ``retrieval_skills`` — 检索来源, an optional list of skill names. Empty /
unset keeps today's collector tools; a non-empty list tells material
collection to call those skills.
- ``enabled`` — 启用/停用; creation always defaults to True (the caller cannot
choose it) and a dedicated toggle flips it later.
- ``created_by`` — 创建用户名 (audit-only display field).
Fresh deployments get the two built-in outlines (通用分析结构 / 递进式论证结构)
seeded by ``ensure_defaults`` — see ``defaults.py``.

"""Canonical owner resolution for a thread's filesystem paths.
Task-deeplink conversations (those whose ``threads_meta.metadata.taskId`` is
set — rwfx / 3qfx / xdfx) are **shared across all users**: any logged-in
account may open the same conversation (enforced by the ``taskId`` escape
branches in :mod:`deerflow.persistence.thread_meta.sql`). But the agent's
generated files (md / artifacts) and uploads live under a *per-user* directory::
The agent's generated files (md / artifacts) and uploads live under a
*per-user* directory::
{base_dir}/users/{user_id}/threads/{thread_id}/user-data/...
If that ``{user_id}`` were the **current login**, account B opening a shared
task conversation would resolve to an empty ``users/B/...`` directory and 404
on every file account A generated — which is exactly the "切换账号后生成的 md
文件找不到" bug.
Using the request context alone is not reliable for filesystem lookup: an
internal call or a context propagation edge case resolves to ``users/default``
even though the authenticated route has already verified access to a persisted
thread. The thread creator is an immutable, stable filesystem bucket, so all
persisted threads resolve to ``threads_meta.user_id``. Task-deeplink and
roundtable threads additionally need this because they can intentionally be
reopened by another account.
To keep the *file* layer consistent with the *conversation-sharing* layer, all
path resolution for a task-shared thread must use one stable user bucket: the
thread's **creator** (``threads_meta.user_id``). That value is fixed at thread
creation and never changes, so every account resolves to the same physical
directory.
Personal (non-task) threads are unaffected: their creator is always the only /
current user, so :func:`resolve_path_user_id` returns exactly what
``get_effective_user_id`` would have. On any failure (no DB, missing row,
memory-mode store) it falls back to the current login, so behaviour degrades
safely to the pre-fix semantics.
For missing metadata rows (legacy/memory-mode threads), resolution safely falls
back to the current login.
