# Calendar Reminder Unified Interaction Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 交付“系统通知主触达 + 前台统一提醒面板”的提醒链路，保证 iOS/Android 在前台、后台、终止态都可执行“稍后提醒”和“取消并归档（内部 archive）”。

**Architecture:** `LocalNotificationService` 仅做调度与平台桥接；`ReminderActionExecutor` 作为唯一动作执行器；新增 `ReminderPresentationCoordinator` + `ReminderActionSheet` 负责前台展示；新增持久化幂等与 cold-start 回放，避免动作丢失/重复执行。

**Tech Stack:** Flutter, flutter_local_notifications, SharedPreferences, Dart isolate callback, AndroidManifest receiver, iOS AppDelegate callback, Flutter tests.

## Execution Notes

- 任务顺序不可打乱：协议 -> 动作语义 -> 幂等 -> 回放 -> 桥接 -> UI -> 平台 -> 清理。
- 每个任务只做最小改动并回归对应测试。
- 视觉组件严格使用 `apps/lib/core/theme/design_tokens.dart`。
- 若实现中与 spec 冲突，先改 spec/协议再继续写代码。
