项目定位

FTB 是一个面向中小型研发团队的项目管理平台,集成 AI 能力辅助决策。核心层级:

产品Product → 项目Project → 版本Version → 需求/任务/用例/Bug

不是给测试团队的工具,也不是 Jira 替代品。核心目标是让产品/项目经理在一个页面看到:"开发完了吗 → 验收过了吗 → 还有多少 BUG → 能不能发布"

心智模型(重要)

系统设计遵循三条维度线的分离:

语义线Why         执行线How         质量线Quality
─────────────────    ─────────────────     ────────────────
Requirement          Version               TestCase
解释为什么做           驱动状态流转            └─ Bug
不参与流程             所有状态看版本           质量闭环

Requirement需求= 语义层,解释功能范围和业务原因,不驱动流程。 Version版本= 执行主线,所有任务归属版本,状态由版本派生;需求只是可选语义分组。 TestCase + Bug = 质量闭环,挂在版本上验收。

关键架构原则

1. 引擎模式(关键)

跨模块的数据派生通过引擎层处理,不是各 store 互相调用:

  • linkage-engine.ts:从 DevTask 状态派生需求"实际进度",新建模块只需在此聚合
  • workspace-engine.ts:聚合 WorkItem 给"与我相关"页面用

引擎是纯函数,输入多个 store 数据,输出统一视图。引擎使应用各模块松耦合,新增模块时不需要改其他模块的代码。

2. 派生胜过存储

时间字段、状态、进度都尽量从底层数据派生,而不是手填:

  • 实际工时 = startDate → completedAt 时间差(精确到 0.5h
  • 阶段耗时 = 所有阶段任务的最早开始 → 最晚完成
  • 需求开发状态 = 从 DevTask 状态聚合
  • 版本执行态 = 从所有 DevTask + TestCase + Bug 聚合
  • 阶段进度 = 已完成子任务/总子任务

3. 时间戳精确到分钟

所有"实际开始/完成"时间都是 ISO 时间戳(含时分秒),不是日期。展示时统一 slice(0, 16).replace('T', ' ')

4. 数据联动

修改 A 影响 B 时,B 通过 filter A 派生,不要双向写。例:

  • 需求关联到版本:需求设 versionId,版本详情 requirements.filter(r => r.versionId === id)
  • 任务/用例归属版本:新数据优先使用 versionId;旧 DevTask 可通过 requirementId -> Requirement.versionId 兼容推导
  • 删除版本清理孤儿数据PlanTask/DevTask/TestCase/Bug + 释放 Requirement.versionId

状态机概览

实体 状态流转
Requirement pending_review → adopted → planned → developing → testing → released → closedrejected 可回 pending_review
VersionPlan pending → in_progress → completed
DevTask todo → in_progress → testing → submitted终态提测=已完成)
TestCase pending → running → passed/failed/blocked
Bug open → fixing → fixed → verifying → closed/rejected

DevTask 没有"已完成"状态,"已提测"就是终态——开发交付完成,后续 Bug 单独流转。

数据持久化

当前 V2.4 分层: AppData 兼容写入 + 关系表快读/同步 + 领域 CRUD 主写迁移

兼容写入层仍使用通用服务端文档表 app_data

  • 后端:apps/server/src/modules/data/ 提供 GET/PUT /api/v1/data/:key
  • 数据库Prisma AppData 模型,表名 app_datakey 为主键,value 为 JSONB
  • 一致性:GET 返回 updatedAt 派生的 version;前端保存时带上最近读取的 version,后端用 key + updatedAt 原子更新,版本不匹配返回 409 APP_DATA_CONFLICT
  • 前端:各 Zustand store 保持现有数据形状,通过 apps/web/lib/server-data.ts 读写服务端
  • 覆盖范围:产品/项目/版本树、需求池、调研/产品方案/UI 计划、开发任务、测试用例、Bug、成员/角色/部门、任务类型、任务工时日志、加班记录
  • 浏览器仅保留登录会话(ftb_auth_session / ftb_auth_persist),不再作为业务数据主存储

关系表层已经包含 V2.2/V2.3 能力:

  • V2.2:高增长业务表使用分区表,并提供版本详情、需求池、工作台和小宝预警的快读 API。
  • V2.3AppData 保存成功后触发关系表同步,让快读路径保持新鲜;同步失败只记日志,不阻塞用户保存。

V2.4 正在推进领域 CRUD 主写迁移Project、Version、VersionPlan、DevTask、TestCase、Bug、Member、TaskCategory、TaskWorklog、Overtime 等主写入需要逐步切到领域 API。迁移前不要恢复业务 localStorage 缓存,避免线上部署后出现多端数据分叉。

目标主源(新方向): 业务主数据必须落到 PostgreSQL 领域关系表。

  • app_data 不再作为长期事实源,只保留迁移、回填、兼容读取和故障排查价值。
  • 新增业务模块不得新增 AppData key 作为主存储必须先设计关系表、Prisma model 和领域 CRUD API。
  • 现有 AppData key 需要逐步完成一次性迁移、双读校验、关系表写入切换和 JSON fallback 移除。
  • 前端 store 可以继续保留 Zustand 状态形状,但持久化入口要从 saveServerData(key) 迁到领域 API。
  • app_data 删除前必须有备份/导出和数据量核对,不能直接丢弃历史 JSON。

V2 迁移阶段边界:

  • V2.1 先把业务数据从浏览器移到服务端 AppData解决部署和清站点数据丢失问题。
  • V2.2 建关系表、分区、快读 API 和小宝摘要读取,写入仍走 AppData。
  • V2.3 在 AppData 保存成功后非阻塞同步关系表,让快读路径持续有新数据。
  • V2.4 逐领域把主写入口迁到关系表 CRUD领域 API 必须从一开始带资源作用域、当前用户、actorId、基础审计事件入口、分页和索引边界。
  • V2.5 才做 AppData 分阶段退场和 RBAC/审计/一致性收口:先禁写,再双读核对,再移除 fallback最后只读归档/导出,不能直接删历史 JSON。
  • V2.6 在关系表主源稳定后做大数据性能增强和小宝预警后台化;性能基础不后置,增强项包括压测、慢查询治理、缓存/摘要、后台任务、幂等和失败重试。
  • V2.7 面向企业级协作与管理治理V2.8 面向生产硬化与运维闭环生产部署基线已经存在V2.8 重点是备份恢复演练、发布 smoke test、监控告警、日志检索、迁移回滚和运维手册。

生产部署层2026-07-01

当前仓库已补齐云服务器生产部署基线:

  • Dockerfile.web:以 monorepo 根目录为 build context构建 @ftb/shared 和 Next.js 前端,运行 pnpm --filter web start
  • Dockerfile.server:构建 @ftb/shared 和 NestJS 后端,执行 prisma generate,运行 pnpm --filter server start:prod
  • docker-compose.prod.yml:编排 webserverpostgresredisnginx 五个服务,服务间通过 Docker 内网通信,对外只暴露 Nginx 80 端口。
  • docker-compose.local.yml:本地服务器/局域网部署入口,同样编排五个服务,默认对外暴露 8080,使用独立 local_* volumes避免与云服务器生产数据混用。
  • deploy/nginx/default.conf.template:同域反向代理,/api/ 转发到 NestJS其他路径转发到 Next.js。
  • .env.production.example / .env.local-server.example:生产和本地服务器配置模板;正式部署复制为 .env.production.env.local-server,不提交真实密钥。

生产持久化边界:

  • 业务主数据在 PostgreSQL postgres_data volume 中。
  • Redis AOF 在 redis_data volume 中。
  • AI Provider 配置文件在 server_data volume 中,对应容器路径 /app/apps/server/data

生产数据库初始化使用 Prisma migrationpnpm --filter server db:deploy。本地开发仍可使用 pnpm db:migrate

权限模型(轻量)

V1 仅做前端校验,无后端鉴权:

  • 版本 members 字段限定参与者
  • 版本列表/详情按 members.contains(currentUser) 过滤
  • 创建版本时自动加入创建者
  • 版本 members 为空时所有人可见(兼容旧数据)

V2 接入后端后改为基于 ProjectMember 表的 RBACOwner/Admin/Member/Viewer

AI Agent 层

详细规范见 agent-spec.md。要点:

  • AI Agent 不是一个独立服务,而是嵌在前端的"特定调用入口"。当前 V3.1 仅 Prototype Decompose Agent。
  • Agent 写入数据时必须带 aiDraft: true 标记,列表中视觉区分(紫色边)。用户编辑后自动清除标记。
  • DevTask / TestCase 加入 references[] 字段,记录任务/用例的来源(需求 / 原型批注。Agent 和人工创建均强制至少 1 条引用。
  • 原型中有明确功能但没有匹配到关联需求时AI 可以生成无需求ID分组草案写入任务/用例的 requirementName,不创建 Requirement不加入关联需求列表。
  • 原型链接不在 Version 上独立存储,而是来自产品方案 (VersionPlan type=product) 已完成计划的 resultUrl。约定:提交产品方案的成果就是原型。
  • AI 服务实现走 NestJS 后端apps/server/src/modules/ai/),不走 Next.js API Route。
  • API Key 通过 /admin/ai-config 页面配置(仅超管可见),存到 apps/server/data/ai-config.json,不入 git环境变量 ANTHROPIC_API_KEY 作为兜底。

新增涉及 AI 的实体字段:

实体 字段 类型 说明
DevTask versionId string 执行归属版本无需求ID分组也通过它进入版本
DevTask requirementId string? 正式需求 ID无需求ID分组为空
DevTask requirementName string? 无正式需求 ID 时的展示分组名
DevTask references Reference[]? 引用来源(需求/原型批注)
DevTask aiDraft boolean? AI 草案标记
DevTask aiDraftAt string? AI 生成时间戳
DevTask aiEstimateHours number? AI 预估耗时;执行人预估仍写 estimateHours
TestCase requirementName string? 无正式需求 ID 时的展示分组名
TestCase references Reference[]? 同上
TestCase aiDraft boolean? 同上
TestCase aiDraftAt string? 同上
TestCase aiEstimateHours number? AI 预估耗时;执行人预估仍写 estimateHours

版本模块规则层V2.2 设计约束)

版本详情里的计划完成、需求候选和任务类型映射必须走规则层:

  • version-plan-workflow.ts:调研/产品方案/UI 设计的子任务、需求覆盖、成果提交和完成条件。
  • requirement-selector.ts:当前版本所属项目下可关联需求的候选筛选,默认只返回 status === 'adopted' 的项目需求。
  • task-category.tsDevTask/TestCase 共用任务类型字典,id 用于存储AI 输出的 taskTypeName 必须是可复用类型;可复用开发类型可在采纳时自动追加到字典,测试用例未知类型回退到已有测试分类,code 仅作可选语义映射。

页面组件只消费规则层输出,不直接拼完成条件或候选筛选条件。

Production Runtime Version Layer (2026-07-06)

Production deployment now treats CI-built Docker images as the release artifact. Dockerfile.web and Dockerfile.server accept APP_VERSION, APP_BUILD_TIME, and image tag build metadata; docker-compose.prod.yml pulls immutable WEB_IMAGE and SERVER_IMAGE tags instead of relying on deployment-side rebuilds.

The server exposes GET /api/v1/health/version, returning the running server commit/version metadata. The web app embeds NEXT_PUBLIC_APP_VERSION at build time and shows a refresh prompt when the browser is still on an older frontend bundle than the server runtime.

GitHub Actions is the production release orchestrator: build and push images, SSH to the server, update .env.production image tags, pull images, run pnpm --filter server db:deploy, restart Compose services, and verify /api/v1/health/version against the current commit SHA.

Work Activity Daily Report Layer (2026-06-26)

The personal daily report is derived from two inputs:

  • work-activities: append-only activity records created by successful business actions.
  • task-worklogs: legacy/manual worklog records that still contribute hours and written work content.

work-activity-factory.ts owns the mapping from domain actions to reportable activity semantics. Zustand stores call this factory after a successful operation, then append the result through useWorkActivityStore.

workspace-daily-report.ts remains a pure aggregation engine. It groups today's current-user activity into delivery, progress, creation, risk, and note sections, and also detects in-progress work that started before today but has no activity or progress note today.

This is intentionally not a generic rules engine or event bus. The rule surface is explicit, typed, and local to the workspace/daily-report use case.

Xiaobao Warning Layer (2026-06-29)

Xiaobao Warning is a version-level release-risk capability shown above /workspace in the main navigation. It answers whether a version can ship on the expected release date, why it may not, roughly how long it may slip, and which release window is safer.

The rule surface stays in pure frontend engines:

  • xiaobao-risk.ts: risk score, level, forecast release date, confidence, and current snapshot.
  • xiaobao-risk-evidence.ts: version work aggregation, daily report/activity evidence, and silent-risk detection.
  • xiaobao-risk-trend.ts: daily snapshots, trend detection, and snapshot signatures.
  • xiaobao-risk-ai.ts: AI trigger policy, cache signature, and backend request mapping.

Managers with xiaobao.warning:manage can see all unfinished versions. Non-managers with xiaobao.warning:view can only see unfinished versions where the current user is in version.members.

AI explains rule results only. It writes interpretation cache to xiaobao-risk-insights and never mutates Version, Requirement, DevTask, TestCase, Bug, or Member data. Risk snapshots are saved to xiaobao-risk-snapshots when the page is opened. The first version uses page-triggered analysis rather than a background scheduled Agent.

Per-user warning read state is saved to xiaobao-warning-views. The read marker stores userId + versionId + risk signature, so the sidebar can turn the Xiaobao badge blue when any visible risk has a completed unread update, then return to the red risk-count badge after the user opens every updated warning. AI interpretation that is still generating only shows the "updating" notice and must not produce the blue update badge yet.

V2.2 Partitioned Domain Data Layer (2026-07-03)

V2.2 starts the move from AppData JSON documents to relation tables for high-volume domains. The first database foundation is partitioned from the start so future growth does not require a disruptive rewrite of primary keys, unique constraints, and foreign-key references.

High-growth business tables use fixed hash partitions:

  • requirements: hash partitioned by product_id; primary key is (id, product_id).
  • dev_tasks, test_cases, and bugs: hash partitioned by version_id; primary key is (id, version_id).

Append-only evidence and history tables use range partitions by created_at:

  • work_activities
  • task_worklogs
  • overtime_records
  • xiaobao_risk_snapshots
  • xiaobao_risk_insights
  • ai_logs

Partitioned tables must include the partition key in every primary key and business unique constraint. Cross-table references to partitioned tables use composite foreign keys when the referencing row naturally carries the partition key, for example (requirement_id, requirement_product_id) and (test_case_id, test_case_version_id). Polymorphic activity references remain logical references.

Xiaobao uses two storage shapes: xiaobao_risk_summaries keeps one current row per version for fast reads, while xiaobao_risk_snapshots stores append-only history for trend analysis.

The AppData migration path is staged through a pure mapper plus preview service. AppDataV22MigrationService.preview() reads the allowed app_data keys, maps legacy JSON into partition-key-ready rows, and reports row counts plus skipped records before any insert path is enabled.

The first V2.2 read layer is query-first and AppData-compatible. V22QueryModule exposes scoped read APIs for version detail, requirement pool, workspace, and Xiaobao warning summaries:

  • Version detail reads only the current version's requirements, plans, dev tasks, test cases, and bugs.
  • Requirement pool queries require productId, so list/search/filter operations stay on the requirements.product_id partition key.
  • Workspace reads only the current user's unfinished plans, dev tasks, test cases, and bugs.
  • Xiaobao warning reads xiaobao_risk_summaries first, then maps the precomputed summary into the existing warning UI shape.

During the V2.2 compatibility window, writes still go through the existing AppData stores. The frontend consumes V2.2 relation-table results for render-heavy pages and falls back to AppData only when the V2.2 read is unavailable or empty. This is a migration bridge, not the target steady state.

V2.3 AppData-to-Relational Write Sync Layer (2026-07-03)

V2.3 closes the first compatibility gap after V2.2: AppData remains the frontend write source only during the compatibility window, but successful PUT /api/v1/data/:key calls now trigger a backend relation-table sync.

DataService writes AppData with the existing optimistic-lock rules first. After the AppData write succeeds, it calls AppDataV23SyncService.syncAfterAppDataPut(key). Sync failures are logged and do not fail the user save during this compatibility window. The next phase must replace AppData writes with domain CRUD writes so relation tables become the source of truth.

AppDataV23SyncService reuses the V2.2 pure mapper, then writes only the table family affected by the changed AppData key:

  • requirements is replaced by product_id scope.
  • version_plans, dev_tasks, test_cases, and bugs are replaced by version_id scope.
  • work_activities, task_worklogs, overtime_records, xiaobao_risk_snapshots, and xiaobao_risk_insights remain append-oriented with duplicate skipping.
  • xiaobao_risk_summaries is refreshed from risk snapshots and marked dirty=true when plans, tasks, test cases, bugs, activities, worklogs, or overtime change.

The server also has lightweight observability for this phase: a global API timing interceptor logs slow HTTP requests, and PrismaService logs slow query events. Thresholds are controlled by API_SLOW_REQUEST_MS and PRISMA_SLOW_QUERY_MS.

Current Backend Migration Boundary (2026-07-08)

Current source-of-truth boundary:

  • Product and Requirement have domain CRUD modules.
  • Project, Version, VersionPlan, DevTask, TestCase, Bug, Member, TaskCategory, TaskWorklog, Overtime, and WorkActivity relation models exist for V2.2/V2.3 mapping and fast reads, but their frontend write paths still mostly go through AppData stores.
  • products-overview remains the primary document for the product/project/version tree until Project and Version write APIs replace it.
  • V2.2 read APIs and V2.3 relation sync are compatibility infrastructure, not proof that every relation model already has a public CRUD API.
  • packages/shared still contains early Requirement/Task status enums. Before switching frontend writes to domain APIs, align shared enums with the current workflow statuses in this document.
