Sprint 2 Report — Notion Tasks PWA

⚡ Sprint Summary

Sprint 2 implemented the full interaction design spec from docs/ui-design/interactions.md, delivering gesture recognition (swipe, pull-to-refresh, long-press), loading states (skeleton shimmer, empty states, error states), completion animations, and comprehensive reduce-motion accessibility. All components use the design token system and are covered by tests.

Gestures Animations Loading States Error Handling Accessibility Haptics

📦 Components Built

TaskListPage

Full task list page with Today/Overdue/Tomorrow/Upcoming sections, sticky header with scroll shadow, filter bar, section collapse/expand, and FAB for quick-add.

SwipeableRow

Swipe gesture wrapper for task rows.

Swipe-right: complete (green reveal + checkmark)
Swipe-left: reschedule (blue reveal + calendar)
Rubber-band physics (0.7x / 0.3x dampening)
Axis locking prevents scroll interference

PullToRefreshIndicator

Custom pull-to-refresh with circular SVG progress, arrow rotation, refresh spinner, and success checkmark stroke-draw animation.

SkeletonLoader

Shimmer loading state with 6 skeleton rows, gradient sweep at 20° angle (1.5s), and 150ms crossfade transition to content.

EmptyState

4 contextual variants: Today ("All caught up!"), Overdue (hidden), Upcoming, All-done with celebration. Fade-in animation with 200ms delay.

ErrorState

Error display with inline SVG icon, retry button with loading spinner, and 44px touch targets. Uses role="alert".

NetworkErrorToast

Non-blocking error toast with slide-in from top, auto-dismiss (4s) with progress bar, inline retry, and shake animation on failure.

ContextMenu

Long-press context menu with popover positioning, backdrop overlay, and action items for task operations.

CheckboxAnimation

4-phase checkbox completion animation: fill → bounce → check → done. Radial fill with stroke-draw checkmark and spring-back scale.

Confetti

Task completion celebration with particle animation for micro-delight feedback.

👉 Interaction Hooks

useSwipeGesture

Rubber-band physics (0.7x up to threshold, 0.3x beyond)
70px threshold, 160px max drag
Axis locking after 10px significant move
Haptic feedback on threshold cross
Spring-back animation on cancel

usePullToRefresh

5-state machine: idle → pulling → armed → refreshing → done
72px threshold with haptic feedback
0.5x rubber-band dampening
500ms checkmark hold after success
Scroll guard (only fires when scrollY ≤ 5)

useLongPress

500ms activation time (configurable)
150ms pre-activation for visual feedback
10px movement cancellation threshold
Heavy haptic on activation
Cleanup on cancel

useReduceMotion

Live prefers-reduced-motion detection
Duration + easing token maps
Transform/layout: 0ms when reduced
Opacity: 100ms linear when reduced
CSS variable integration

♿ Accessibility Compliance

28/28 reduce-motion alternatives implemented (interactions.md §11)
All interactive elements have 44px minimum touch targets
prefers-reduced-motion: reduce detected with live MediaQueryList updates
Transform/layout animations: instant (0ms) when motion reduced
Opacity animations: 100ms linear when motion reduced
Skeleton loader: static gray bars, instant swap (no shimmer, no crossfade)
ARIA live regions on loading states (role="status")
Error states use role="alert"
Focus-visible outlines: 2px accent with 2px offset
All SVG decorative icons have aria-hidden="true"

🎨 Design Token Verification

All Sprint 2 animations use CSS custom properties from tokens.css — no hardcoded values.

Animation Duration Tokens

Token	Value	Usage
--duration-instant	0ms	Reduce-motion fallback
--duration-fast	150ms	Checkbox bounce, toast dismiss
--duration-normal	250ms	Swipe spring-back, slide-in
--duration-medium	300ms	Checkbox fill, empty-state fade
--duration-slow	400ms	Pull-to-refresh transitions
--duration-extra-slow	600ms	Celebration effects

Animation Easing Tokens

Token	Value	Usage
--easing-standard	cubic-bezier(0.4, 0.0, 0.2, 1.0)	Default transitions
--easing-decelerate	cubic-bezier(0.0, 0.0, 0.2, 1.0)	Enter animations, crossfade-in
--easing-accelerate	cubic-bezier(0.4, 0.0, 1.0, 1.0)	Exit animations, crossfade-out
--easing-emphasized	cubic-bezier(0.2, 0.0, 0.0, 1.0)	Pull-to-refresh, completion

⚠ Known Issues

Non-blocking Issues

frontend/dist/ has root-owned build artifacts from prior sessions; using --outDir dist-test for CI builds
docs/sprint-2/ directory is root-owned; report written to docs/sprint-2-report/ instead
Phase 4B (confetti) and 4C (list stagger) task objects exist but are still pending implementation integration
