+# ADR 0004: Path-Based URL Strategy for Deep Linking
+
+**Status**: Accepted
+
+**Date**: 2025-12-21
+
+**Deciders**: Engineering Team
+
+**Context**: The app needed shareable, bookmarkable URLs for festival drinks, breweries, and styles. Two approaches were considered: hash-based URLs (`/#/drink/123`) and path-based URLs (`/drink/123`). The app was pre-release with no existing shared URLs or search engine indexing, so there were no backward-compatibility constraints.
+
+---
+
+## Decision
+
+We adopted **festival-scoped, path-based URLs** with GoRouter and `usePathUrlStrategy()`.
+
+### URL Structure
+
+```
+/{festivalId}                    → Festival home (drinks list)
+/{festivalId}/favorites          → Favorites for this festival
+/{festivalId}/drink/{drinkId}    → Drink detail
+/{festivalId}/brewery/{id}       → Brewery detail
+/{festivalId}/style/{styleName}  → Style detail (lowercase canonical)
+/{festivalId}/info               → Festival info
+/about                           → About (global, not festival-scoped)
+```
+
+### Key Design Choices
+
+1. **Festival ID as URL root** -- every drink/brewery/style URL is scoped to a festival, enabling cross-festival deep links
+2. **Lowercase canonical style URLs** -- `buildStylePath()` lowercases style names for consistent URLs
+3. **URL encoding** -- all user-provided IDs are encoded via `Uri.encodeComponent()`
+4. **Pre-release advantage** -- no redirect logic or legacy URL support needed
+
+---
+
+## Alternatives Considered
+
+### Hash-Based URLs (`/#/drink/123`)
+
+- Simpler: no server-side SPA routing config needed
+- Rejected because: poor SEO, unprofessional appearance, not shareable on social media
+
+### Flat URLs without festival scoping (`/drink/123`)
+
+- Simpler routing, fewer path segments
+- Rejected because: can't distinguish same drink ID across different festivals; can't share a link to "this year's festival"
+
+---
+
+## Consequences
+
+### Positive
+
+- Clean, shareable URLs that work on social media
+- Festival context is always visible in the URL
+- Browser back/forward works correctly
+- Bookmarks and shared links are self-contained
+
+### Negative
+
+- Requires SPA fallback routing on the server (Cloudflare Pages `_redirects` or `--proxy` flag on http-server)
+- Detail routes currently lack festival ID validation (documented as known limitation, see todos.md H3)
+- Festival selector UI doesn't update the URL when switching festivals (see todos.md C3)
+
+---
+
+## Implementation
+
+- **Router**: `lib/router.dart` (GoRouter configuration)
+- **URL builders**: `lib/utils/navigation_helpers.dart`
+- **E2E tests**: `test-e2e/routing.spec.ts` (Playwright URL smoke tests)
+- **Server config**: `--proxy` flag on http-server for SPA fallback

+# ADR 0005: E2E Testing Strategy -- Playwright for URL Smoke Tests
+
+**Status**: Accepted
+
+**Date**: 2025-12-21
+
+**Deciders**: Engineering Team
+
+**Context**: The app needed automated end-to-end testing to validate routing and deep linking. Two approaches were evaluated: Patrol with Firebase Test Lab (native Flutter E2E on real Android devices) and Playwright (browser-based testing). Flutter web renders to a `<canvas>` element, which makes traditional DOM-based testing largely ineffective for UI interactions.
+
+---
+
+## Decision
+
+We adopted **Playwright for URL and routing smoke tests only**, and deferred native E2E testing.
+
+Playwright tests verify:
+- URL routing works (correct URLs after navigation)
+- Browser back/forward/refresh preserves routes
+- No critical console errors on page load
+- Basic ARIA label presence (accessibility smoke test)
+
+Playwright tests **do not** verify:
+- Visual appearance, layout, or rendered text
+- Widget interactions (tapping buttons, filling forms)
+- User flows (search, filter, favorite)
+- Canvas-rendered content
+
+Widget interactions are covered by Flutter's own `testWidgets` framework in `test/`.
+
+---
+
+## Alternatives Considered
+
+### Patrol + Firebase Test Lab
+
+A detailed plan was created (see `docs/planning/archive/patrol-firebase-testing/`) proposing:
+- Native Flutter E2E tests using the Patrol framework
+- Execution on real Android devices via Firebase Test Lab free tier (15 tests/day)
+- 4-5 week implementation timeline across 5 phases
+
+**Why it was not implemented:**
+- Significant setup complexity (Firebase Test Lab, GCP service accounts, Android instrumentation builds)
+- 4-5 week implementation investment for a pre-release app
+- Free tier limit (15 tests/day) constrains CI usage
+- Flutter widget tests already cover interaction flows effectively
+- The immediate need was validating URL routing for the deep linking feature, not full native E2E
+
+**When to reconsider:**
+- If the app ships on Android/iOS and needs device-specific testing (permissions, system dialogs, push notifications)
+- If visual regression testing becomes important
+- If Flutter widget tests prove insufficient for catching real-world bugs
+
+### Flutter Integration Tests
+
+Flutter's built-in `integration_test` package was considered but not prioritised. It would run the full app in a test harness and can interact with widgets directly. This remains a valid option for future investment (tracked in todos.md item #1).
+
+---
+
+## Consequences
+
+### Positive
+
+- Fast to implement (2 test files, ~440 lines)
+- Validates the most critical web concern: URL routing works correctly
+- Runs in CI without special infrastructure
+- ARIA label checks enforce accessibility as a side effect
+- No ongoing cost or quota limits
+
+### Negative
+
+- Cannot test actual user flows through the UI
+- Cannot verify that the correct screen renders for a given URL
+- Flutter canvas rendering means Playwright can never do meaningful UI testing for this app
+- Gap between "URL works" and "screen works" -- a route could return 200 but render an error state
+
+---
+
+## Implementation
+
+- **Config**: `playwright.config.ts`
+- **Tests**: `test-e2e/app.spec.ts` (loading, console errors, ARIA), `test-e2e/routing.spec.ts` (URL routing, browser history)
+- **Approach doc**: `docs/tooling/flutter-web-testing.md`
