+# [FEATURE] Add Google Calendar support
+
+## Description
+Add Google Calendar support.
+
+## User Story
+As a user, I want my Google Calendar events displayed so I have a unified daily view.
+
+## Technical Context
+- New integration following existing patterns in `internal/api/`
+- OAuth2 flow required; store refresh token in `sync_tokens` table
+- New partial for calendar events display
+
+## Test Strategy
+
+### Unit Test (Red)
+**File:** `internal/api/gcal_test.go`
+
+```go
+func TestParseCalendarEvents(t *testing.T) {
+    // Mock Google Calendar API response
+    // Assert events parsed correctly with title, time, all-day flag
+}
+
+func TestGCalClient_FetchEvents(t *testing.T) {
+    // Mock HTTP client
+    // Assert correct API calls made
+    // Assert events returned in expected format
+}
+```
+
+### Integration Test (Red)
+Test cache/store roundtrip for events.
+
+```go
+func TestGCalEventsCache(t *testing.T) {
+    // Store events in cache
+    // Retrieve from cache
+    // Assert data integrity
+}
+```
+
+## Proposed Approach
+
+1. **OAuth Setup:**
+   - Add `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET` to config
+   - Implement OAuth2 flow with PKCE
+   - Store refresh token in `sync_tokens` table
+
+2. **API Client:**
+   - Create `internal/api/gcal.go` implementing interface pattern from existing clients
+   - Use `google.golang.org/api/calendar/v3`
+   - Fetch events for configurable date range (default: today + 7 days)
+
+3. **Data Model:**
+   - Add `calendar_events` table or reuse existing structure
+   - Handle all-day vs timed events
+
+4. **UI:**
+   - New partial: `partials/gcal-events.html`
+   - Integrate into existing tabs or new calendar tab
+
+## Traps to Avoid
+- **All-day events:** Google returns these differently (date vs dateTime)
+- **Timezone:** Events have their own timezone; convert to user's local
+- **Recurring events:** Decide whether to expand or show as single item
+- **Token refresh:** Handle expired access tokens gracefully
+
+## Affected Components
+- `internal/api/gcal.go` (new)
+- `internal/api/gcal_test.go` (new)
+- `internal/api/interfaces.go` (add interface)
+- `internal/config/config.go`
+- `internal/store/sqlite.go` (new table/queries)
+- `web/templates/partials/gcal-events.html` (new)
+- `cmd/dashboard/main.go` (wire up client)
+
+## Definition of Done
+- [ ] OAuth2 flow authenticates with Google
+- [ ] Events fetched from Google Calendar API
+- [ ] Events cached in SQLite
+- [ ] Events displayed in UI
+- [ ] All-day and timed events handled correctly
+- [ ] Token refresh works
+- [ ] Unit and integration tests pass
