+## 1. 背景与动机
+
+当前插件是「数据录入系统」，不是「赚钱工具」。一人 IT 服务公司的核心痛点：
+
+1. **钱从哪里来？** — 商机跟进靠人记，没有自动提醒、没有漏斗分析
+2. **项目做到哪了？** — 任务状态和工时手动填，跟合同金额/应收款脱节
+3. **钱收回来了吗？** — 报价→合同→开票→收款割裂，没有串联
+4. **运维服务会不会忘？** — 巡检计划写了没人催，SLA 超时了才知道
+5. **税和利润算不清？** — 收支分散在不同表里，月底做账要手动汇总
+
+**问题根因：** 平台已有 trigger_events、settings、templates、cascade_from、visible_when、validation 六大能力，但两个插件完全没有使用。
+
+**改进目标：** 纯插件层增强，三层递进：
+- Layer 1: 智能业务引擎 — 让系统主动驱动用户做事
+- Layer 2: 仪表盘重构 — 一个页面掌控全局
+- Layer 3: 专业输出 — 一键生成报价单/发票/合同 PDF
+
+---
+
+## 2. Layer 1: 智能业务引擎 — freelance 插件
+
+### 2.1 Settings（插件配置页）
+
+一次性配置公司信息和业务偏好，后续自动生效：
+
+```toml
+[settings]
+
+  # ── 基本信息 ──
+  [[settings.fields]]
+  name = "company_name"
+  display_name = "公司名称"
+  field_type = "text"
+  required = true
+  group = "基本信息"
+
+  [[settings.fields]]
+  name = "currency_symbol"
+  display_name = "货币符号"
+  field_type = "text"
+  default_value = "¥"
+  group = "基本信息"
+
+  # ── 财务 ──
+  [[settings.fields]]
+  name = "default_tax_rate"
+  display_name = "默认税率(%)"
+  field_type = "number"
+  default_value = 6
+  range = [0.0, 100.0]
+  group = "财务"
+
+  # ── 提醒 ──
+  [[settings.fields]]
+  name = "payment_reminder_days"
+  display_name = "收款提前提醒(天)"
+  field_type = "number"
+  default_value = 3
+  range = [1.0, 30.0]
+  group = "提醒"
+
+  [[settings.fields]]
+  name = "notify_contract_expiring"
+  display_name = "合同到期提醒"
+  field_type = "boolean"
+  default_value = true
+  group = "提醒"
+
+  [[settings.fields]]
+  name = "notify_payment_overdue"
+  display_name = "逾期收款提醒"
+  field_type = "boolean"
+  default_value = true
+  group = "提醒"
+
+  [[settings.fields]]
+  name = "notify_opportunity_followup"
+  display_name = "商机跟进提醒"
+  field_type = "boolean"
+  default_value = true
+  group = "提醒"
+```
+
+### 2.2 Trigger Events（自动事件驱动）
+
+关键操作时自动发通知，把"人找事"变"事找人"：
+
+```toml
+[[trigger_events]]
+name = "opportunity_stage_changed"
+display_name = "商机阶段变更"
+description = "商机阶段发生变化时通知，特别是成交或失败"
+entity = "opportunity"
+on = "update"
+
+[[trigger_events]]
+name = "contract_status_changed"
+display_name = "合同状态变更"
+description = "合同状态变化时检查到期预警"
+entity = "contract"
+on = "update"
+
+[[trigger_events]]
+name = "invoice_status_changed"
+display_name = "发票状态变更"
+description = "发票状态变化时检查逾期收款"
+entity = "invoice"
+on = "update"
+
+[[trigger_events]]
+name = "task_status_changed"
+display_name = "任务状态变更"
+description = "任务完成或取消时通知"
+entity = "task"
+on = "update"
+
+[[trigger_events]]
+name = "expense_created"
+display_name = "新支出记录"
+description = "记录新支出时通知"
+entity = "expense"
+on = "create"
+```
+
+### 2.3 Cascade（智能联动下拉）
+
+选客户后自动过滤其关联数据：
+
+**contract 实体新增：**
+```toml
+  # client_id 选择后，opportunity_id 自动过滤只显示该客户的商机
+  [[schema.entities.fields]]
+  name = "opportunity_id"
+  field_type = "uuid"
+  display_name = "关联商机"
+  ref_entity = "opportunity"
+  cascade_from = "client_id"
+  cascade_filter = "client_id"
+
+  # client_id 选择后，quote_id 自动过滤只显示该客户的报价
+  [[schema.entities.fields]]
+  name = "quote_id"
+  field_type = "uuid"
+  display_name = "关联报价"
+  ref_entity = "quote"
+  cascade_from = "client_id"
+  cascade_filter = "client_id"
+```
+
+**invoice 实体新增：**
+```toml
+  # client_id 选择后，project_id 自动过滤
+  [[schema.entities.fields]]
+  name = "project_id"
+  field_type = "uuid"
+  display_name = "关联项目"
+  ref_entity = "project"
+  cascade_from = "client_id"
+  cascade_filter = "client_id"
+
+  # client_id 选择后，contract_id 自动过滤
+  [[schema.entities.fields]]
+  name = "contract_id"
+  field_type = "uuid"
+  display_name = "关联合同"
+  ref_entity = "contract"
+  cascade_from = "client_id"
+  cascade_filter = "client_id"
+```
+
+**time_entry 实体新增：**
+```toml
+  # project_id 选择后，task_id 自动过滤只显示该项目的任务
+  [[schema.entities.fields]]
+  name = "task_id"
+  field_type = "uuid"
+  display_name = "关联任务"
+  ui_widget = "entity_select"
+  ref_entity = "task"
+  ref_label_field = "title"
+  ref_search_fields = ["title"]
+  cascade_from = "project_id"
+  cascade_filter = "project_id"
+```
+
+### 2.4 Visible When（条件显示）
+
+只在有意义时才显示字段：
+
+| 实体 | 字段 | 条件 |
+|------|------|------|
+| invoice | payment_date | `status == 'paid' \|\| status == 'partial'` |
+| contract | paid_amount | `status != 'drafting'` |
+| task | actual_hours | `status != 'todo'` |
+| quote | total_amount | `status != 'draft'` |
+
+### 2.5 Validation（字段校验）
+
+```toml
+  # client 实体 - email 字段增加校验
+  [[schema.entities.fields]]
+  name = "email"
+  field_type = "string"
+  display_name = "邮箱"
+  validation = { pattern = "^[^@]+@[^@]+\\.[^@]+$", message = "请输入有效的邮箱地址" }
+
+  # client 实体 - phone 字段增加校验
+  [[schema.entities.fields]]
+  name = "phone"
+  field_type = "string"
+  display_name = "电话"
+  validation = { pattern = "^1[3-9]\\d{9}$", message = "请输入有效的手机号" }
+```
+
+---
+
+## 3. Layer 2: 仪表盘重构 — freelance 插件
+
+将占位符仪表盘升级为真正的指挥中心。通过 `widgets` 声明告诉平台该展示什么：
+
+```toml
+[[ui.pages]]
+type = "dashboard"
+label = "工作台"
+icon = "DashboardOutlined"
+
+  # ── 财务概览卡片 ──
+  [[ui.pages.widgets]]
+  type = "stat_cards"
+  label = "财务概览"
+  cards = [
+    { entity = "invoice", aggregate = "sum", field = "amount", filter = "type == 'payment' && status != 'overdue'", label = "本月收入", icon = "rise", color = "green" },
+    { entity = "expense", aggregate = "sum", field = "amount", label = "本月支出", icon = "fall", color = "red" },
+    { entity = "invoice", aggregate = "sum", field = "amount", filter = "status == 'overdue' || status == 'pending'", label = "应收总额", icon = "dollar", color = "orange" },
+    { entity = "invoice", aggregate = "count", filter = "status == 'overdue'", label = "逾期笔数", icon = "warning", color = "red" }
+  ]
+
+  # ── 紧急待办 ──
+  [[ui.pages.widgets]]
+  type = "action_list"
+  label = "紧急待办"
+  max_items = 5
+  queries = [
+    { entity = "invoice", filter = "status == 'overdue'", label_field = "invoice_number", subtitle_field = "amount", action = "查看", icon = "warning" },
+    { entity = "task", filter = "status != 'done' && status != 'cancelled'", sort = "due_date asc", label_field = "title", subtitle_field = "due_date", action = "处理", icon = "clock" },
+    { entity = "contract", filter = "status == 'active'", sort = "end_date asc", label_field = "title", subtitle_field = "end_date", action = "续约", icon = "file-text" },
+    { entity = "opportunity", filter = "next_follow_up <= today", label_field = "title", subtitle_field = "next_follow_up", action = "跟进", icon = "phone" }
+  ]
+
+  # ── 商机漏斗 ──
+  [[ui.pages.widgets]]
+  type = "funnel"
+  label = "商机漏斗"
+  entity = "opportunity"
+  lane_field = "stage"
+  value_field = "estimated_amount"
+  lane_order = ["visit", "requirement", "quote", "negotiation", "won", "lost"]
+
+  # ── 活跃项目卡片 ──
+  [[ui.pages.widgets]]
+  type = "card_list"
+  label = "活跃项目"
+  entity = "project"
+  filter = "status == 'in_progress'"
+  max_items = 4
+  title_field = "name"
+  subtitle_field = "contract_amount"
+  tags = ["business_type", "status"]
+```
+
+**依赖：** 仪表盘 widgets 渲染需要前端配合解析 `widgets` 声明。数据源来自平台已有的聚合 API（`/count`、`/aggregate`）。

+
+## 4. Layer 3: 专业输出 — freelance 插件
+
+一键生成专业 PDF，替代手动排 Word：
+
+### 4.1 报价单模板
+
+```toml
+[[templates]]
+name = "quote_pdf"

+| Layer 1 | trigger_events | 5 个事件（商机/合同/发票/任务/支出） | 4 个事件（工单/合同/巡检） |
+| Layer 1 | cascade | 4 处联动（合同/发票/工时表单） | 2 处联动（工单/巡检记录） |
+| Layer 1 | visible_when | 4 个条件字段 | 6 个条件字段 |

+| Layer 2 | dashboard widgets | 财务卡片+紧急待办+商机漏斗+项目卡片 | 运维卡片+紧急待办 |
+| Layer 3 | templates | 3 个 PDF（报价单/发票/合同） | 1 个 PDF（维保合同） |
+
+**总计：** 2 个插件 × 3 层增强，从「数据录入」升级为「赚钱工具」。
