Hugging Face 渔业数据和学校 Ocean 服务器是两个独立数据平面。学校的本地渔业镜像是只读缓存：同一路径优先读本地；本地没有的文件自动回退 Hugging Face，因此两个部署使用同一份完整清单。 2. 当用户询问柔鱼/鱿鱼/金枪鱼、FAO、Sea Around Us、SPRFMO、WCPFC、RAM Legacy、GFW、VIIRS、捕捞量、努力量、CPUE、渔船活动或资源评估时： - 如果用户只是问“有哪些数据 / 哪些文件已入库 / live inventory / 能做什么科学问题”，服务端会在用户消息后附加 [HF_FISHERIES_LIVE_CONTEXT]。 - 看到该上下文时，直接依据其中的 Hugging Face main 分支实时文件树回答。 - 仅目录、来源和入库状态问题，不要调用 start_mcp_server，不要重复调用 fisheries inventory/search。 - 必须调用清单工具时，正确示例是 mcp_marine_fisheries_inventory(domain="tuna", keyword="IATTC")；不得把内部 、、 标记作为普通文字输出。 - 如果用户要求实际读取字段、记录数、缺失、重复、时间/空间筛选、聚合或CSV导出，先从search/inventory结果取得repository和path，再把两者同时传给 mcp_marine_fisheries_analyze_export；不得改用Web、Shell、Run、JS或子代理，也不得只根据目录元数据回答。 - fisheries_analyze_export 返回 exports/download_urls 时，按 filtered_raw、deduplicated、annual_summary 分别列出文件名和完整下载链接，每个链接只输出一次。 - 工具返回 status=error 时，如实报告 detail；不要给出理论网格数冒充实际记录数。 - “是否已入库”只能依据 live context 中实际出现的路径，不能依据规划清单猜测。 3. 只有当用户请求学校 Ocean 环境数据、CMEMS、ERA5、OISST、OC-CCI、SST、海温、盐度、流速、BGC、混合层、海面高度，或者明确请求 Ocean 文件导出/服务器状态时，才使用 Marine MCP。 4. 同时涉及渔业与 Ocean 环境数据时，Hugging Face 渔业 inventory 由服务端上下文提供，Ocean 部分再使用 Marine MCP。 5. 渔业聚合规则：catch 求和；effort 仅在单位兼容时求和；CPUE 必须使用聚合后总catch÷总effort重算，禁止直接平均月CPUE。 6. GFW apparent fishing hours 是AIS/模型推断的表观作业努力量，不等同于捕捞量或资源丰度；VIIRS 夜光变量是船舶活动证据，cvg 是观测机会/质量控制。 7. 不得把年/月尺度数据伪装成逐日数据，缺失月份必须明确说明。 8. Ocean 查询若用户没有提供日期，不得擅自使用系统当天日期。只有用户明确说“今天/当前/最新”时才按相应意图处理；普通无日期查询应先说明已识别的数据源、变量和区域，并要求补充日期或日期范围。 HF live inventory 判定规则：当 [HF_FISHERIES_LIVE_CONTEXT] 含 SOURCE_LEVEL_RESULTS 时，必须以其中对完整 live tree 计算出的 PRESENT / NOT_FOUND_IN_LIVE_TREE 为准；不要依据 raw path preview 是否展示某来源来判断该来源是否存在。""" BOOT_SYSTEM = f"""你正在初始化本线程的 Marine MCP 工具。 如果当前工具集中已经存在 mcp_marine_marine_health，请调用它一次并立即结束。 否则只允许调用 start_mcp_server： server 必须严格等于 {MARINE_CMD} name 必须严格等于 marine。 成功发现工具后立即结束。禁止任何其他工具、Python、JS、Shell、tool_search 或环境变量检查。""" marine_threads=set() marine_init_tasks={} bootstrap_error=None lock=asyncio.Lock() last_llm_error=None log=logging.getLogger("marine-ui") thread_system_prompts={} thread_user_ids={} thread_upload_ids={} thread_last_data_requests={} thread_recent_history={} thread_compressed_contexts={} class ThreadCreate(BaseModel): user_id:str="" class Chat(BaseModel): thread_id:str prompt:str user_id:str="" upload_ids:list[str]|None=None history:list[dict[str,str]]|None=None class DatasetAvailabilityCheck(BaseModel): date: str variable: str class ProjectDataPackageRequest(BaseModel): project: str max_package_mb: int = 300 include_ocean: bool = True include_tuna: bool = True include_squid: bool = True selected_ocean_keys: list[str] | None = None selected_fisheries_names: list[str] | None = None UI_VERSION = CODE_VERSION _default_project_root = "/data/squid_project_packages" if Path("/data").exists() else "/tmp/squid_project_packages" PROJECT_PACKAGE_ROOT = Path(os.environ.get("PROJECT_PACKAGE_ROOT", _default_project_root)) try: PROJECT_PACKAGE_ROOT.mkdir(parents=True, exist_ok=True) except Exception: PROJECT_PACKAGE_ROOT = Path("/tmp/squid_project_packages") PROJECT_PACKAGE_ROOT.mkdir(parents=True, exist_ok=True) PROJECT_PACKAGE_TTL_SECONDS = int(os.environ.get("PROJECT_PACKAGE_TTL_SECONDS", "86400")) PROJECT_PACKAGE_INDEX = PROJECT_PACKAGE_ROOT / "package-index.json" def _load_project_package_tokens() -> dict[str, dict[str, Any]]: try: raw = json.loads(PROJECT_PACKAGE_INDEX.read_text(encoding="utf-8")) return raw if isinstance(raw, dict) else {} except Exception: return {} def _save_project_package_tokens(tokens: dict[str, dict[str, Any]]) -> None: try: tmp = PROJECT_PACKAGE_INDEX.with_suffix(".tmp") tmp.write_text(json.dumps(tokens, ensure_ascii=False, indent=2), encoding="utf-8") tmp.replace(PROJECT_PACKAGE_INDEX) except Exception: logging.exception("failed to persist project package index") def _cleanup_project_package_tokens() -> None: now = time.time() changed = False for token, meta in list(PROJECT_PACKAGE_TOKENS.items()): path = Path(str(meta.get("path") or "")) expired = now - float(meta.get("created") or 0) > PROJECT_PACKAGE_TTL_SECONDS if expired or not path.exists(): if expired: path.unlink(missing_ok=True) PROJECT_PACKAGE_TOKENS.pop(token, None) changed = True if changed: _save_project_package_tokens(PROJECT_PACKAGE_TOKENS) PROJECT_PACKAGE_TOKENS: dict[str, dict[str, Any]] = _load_project_package_tokens() _cleanup_project_package_tokens() def valid_user_id(user_id): return bool(re.fullmatch(r"[A-Za-z0-9_.:-]{3,128}", user_id or "")) # Per-user UI state (favorites) is stored server-side so authenticated users # can see the same collection from multiple browsers/devices.
