+# Android Nav Restructure & Projects Staleness Fix
+
+> **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:** Replace the Projects bottom-nav tab with a "More" bottom sheet that houses Projects, News, and Calendar; fix stale task data on the project tasks screen.
+
+**Architecture:** The shell's 4th nav item becomes a non-routing action — tapping it shows a `showModalBottomSheet` with the three overflow destinations. `_tabIndex()` maps `/projects`, `/news`, `/calendar` prefixes to index 3 so the "More" tab highlights correctly. News and Calendar are added as stub push-routes now; their real screens are built in subsequent passes. The staleness fix is a single `await` + `ref.invalidate` after returning from task edit.
+
+**Tech Stack:** Flutter, GoRouter, Riverpod, Material 3 `NavigationBar` / `NavigationRail`
+
+---
+
+## Scope
+
+Two independent changes in one pass:
+
+1. **Nav restructure** — `lib/app.dart`
+2. **Staleness fix** — `lib/screens/library/project_tasks_screen.dart`
+
+---
+
+## Design Details
+
+### 1. Nav Restructure (`lib/app.dart`)
+
+**Route changes:**
+- Remove `/projects` from the `ShellRoute` routes list.
+- Add three new top-level `GoRoute` entries (alongside the existing non-shell routes):
+  - `/projects` → `ProjectsScreen()` (moved from shell)
+  - `/news` → stub `Scaffold(body: Center(child: Text('News — coming soon')))`
+  - `/calendar` → stub `Scaffold(body: Center(child: Text('Calendar — coming soon')))`
+- Add route constants to `lib/core/constants.dart`: `news = '/news'`, `calendar = '/calendar'`
+
+**Shell tab list:**
+```dart
+static const _tabs = [
+  Routes.briefing,
+  Routes.knowledge,
+  Routes.conversations,
+];
+```
+(3 entries — "More" is index 3 but handled specially, not a route)
+
+**`_tabIndex()` update:**
+```dart
+int _tabIndex(String location) {
+  for (var i = 0; i < _tabs.length; i++) {
+    if (location.startsWith(_tabs[i])) return i;
+  }
+  // Projects, News, Calendar all highlight "More"
+  if (location.startsWith(Routes.projects) ||
+      location.startsWith(Routes.news) ||
+      location.startsWith(Routes.calendar)) return 3;
+  return 0;
+}
+```
+
+**`onDestinationSelected` update (both `NavigationBar` and `NavigationRail`):**
+```dart
+onDestinationSelected: (i) {
+  if (i == 3) {
+    _showMoreSheet(context);
+  } else {
+    context.go(_tabs[i]);
+  }
+},
+```
+
+**`_showMoreSheet` method on `_ShellState`:**
+```dart
+void _showMoreSheet(BuildContext context) {
+  showModalBottomSheet<void>(
+    context: context,
+    builder: (_) => SafeArea(
+      child: Column(
+        mainAxisSize: MainAxisSize.min,
+        children: [
+          ListTile(
+            leading: const Icon(Icons.folder_outlined),
+            title: const Text('Projects'),
+            onTap: () {
+              Navigator.pop(context);
+              context.push(Routes.projects);
+            },
+          ),
+          ListTile(
+            leading: const Icon(Icons.newspaper_outlined),
+            title: const Text('News'),
+            onTap: () {
+              Navigator.pop(context);
+              context.push(Routes.news);
+            },
+          ),
+          ListTile(
+            leading: const Icon(Icons.calendar_month_outlined),
+            title: const Text('Calendar'),
+            onTap: () {
+              Navigator.pop(context);
+              context.push(Routes.calendar);
+            },
+          ),
+        ],
+      ),
+    ),
+  );
+}
+```
+
+**4th nav destination label:** "More" with `Icons.more_horiz_outlined` / `Icons.more_horiz`.
+
+**NavigationRail note:** The wide-layout rail also gets the same 4 destinations and the same intercept on `onDestinationSelected`.
+
+---
+
+### 2. Projects Staleness Fix (`lib/screens/library/project_tasks_screen.dart`)
+
+**Current (line ~321):**
+```dart
+context.push(Routes.taskEdit.replaceFirst(':id', '${task.id}'));
+```
+
+**Fixed:**
+```dart
+await context.push(Routes.taskEdit.replaceFirst(':id', '${task.id}'));
+ref.invalidate(projectTasksProvider(widget.projectId));
+```
+
+This re-fetches tasks as soon as the user pops back from the task edit screen, eliminating stale data.
+
+---
+
+## What This Does NOT Include
+
+- Real News screen implementation (separate spec/pass)
+- Real Calendar screen implementation (separate spec/pass)
+- Any changes to the web frontend
