+
+## Pattern Overview
+
+**Overall:** Layered modular monolith (single frontend SPA + single backend process)
+
+**Key Characteristics:**
+- Frontend uses React Router + context/hook composition (`frontend/src/App.tsx`, `frontend/src/context/AppContext.tsx`).
+- Backend uses route modules with shared service modules (`backend/src/routes/medications.ts`, `backend/src/services/medications-service.ts`).
+- Data persistence is centralized in Drizzle schema + startup migrations (`backend/src/db/schema.ts`, `backend/src/db/client.ts`).
+
+## Layers
+
+**Frontend Presentation + Orchestration:**
+- Purpose: Render UI, route navigation, manage client state, invoke API.
+- Location: `frontend/src/main.tsx`, `frontend/src/App.tsx`, `frontend/src/pages/`, `frontend/src/context/`, `frontend/src/hooks/`.
+- Contains: pages, modals, app shell, hook-based API callers.
+- Depends on: backend `/api/*`, i18n, shared frontend utils/types.
+- Used by: browser clients.
+
+**Backend HTTP/API Layer:**
+- Purpose: Expose REST endpoints, authenticate/authorize requests, validate input, map to service/db logic.
+- Location: `backend/src/index.ts`, `backend/src/routes/`, `backend/src/plugins/`.
+- Contains: Fastify app setup, route registration, auth middleware.
+- Depends on: services, db client/schema, env plugin.
+- Used by: frontend SPA and API consumers.
+
+**Domain Services Layer:**
+- Purpose: Reusable business logic for scheduling, notifications, stock math, parsing.
+- Location: `backend/src/services/`, `backend/src/utils/`.
+- Contains: reminder scheduler, notification builders/delivery, medication helpers.
+- Depends on: db models and utilities.
+- Used by: routes and startup process.
+
+**Persistence Layer:**
+- Purpose: Define DB schema and keep existing SQLite instances compatible.
+- Location: `backend/src/db/schema.ts`, `backend/src/db/client.ts`, `backend/drizzle/`.
+- Contains: tables, migration execution, backward-compatible alter migrations.
+- Depends on: Drizzle + libsql client.
+- Used by: routes/services.
+
+## Data Flow
+
+### Primary Request Path
+
+1. Frontend page triggers API call via `/api/*` fetch (`frontend/src/pages/PlannerPage.tsx:307`).
+2. Vite proxy rewrites `/api` prefix to backend route root (`frontend/vite.config.ts:23`, `frontend/vite.config.ts:26`).
+3. Fastify route handles request under `/planner/send-email` with auth + validation (`backend/src/routes/planner.ts:141`, `backend/src/routes/planner.ts:158`).
+4. Route loads user settings and dispatches channel delivery helpers (`backend/src/routes/planner.ts:221`, `backend/src/routes/planner.ts:432`, `backend/src/routes/planner.ts:829`).
+
+### Public Share Flow
+
+1. Frontend routes public token URL to shared schedule view (`frontend/src/App.tsx:35`).
+2. Shared schedule component fetches token payload from `/api/share/:token` (`frontend/src/components/SharedSchedule.tsx:311`).
+3. Backend public share route reads token/settings and returns filtered medication schedule (`backend/src/routes/share.ts:125`, `backend/src/routes/share.ts:156`).
+
+**State Management:**
+- Frontend: context-centric state aggregation (`frontend/src/context/AppContext.tsx:248`, `frontend/src/context/AppContext.tsx:1020`).
+- Backend: DB-backed state with runtime scheduler state persisted through notification state utilities (`backend/src/services/reminder-scheduler.ts:42`).
+
+## Key Abstractions
+
+**Auth Context + Guards:**
+- Purpose: unify session/API-key auth across protected routes.
+- Examples: `backend/src/plugins/auth.ts`, `backend/src/routes/settings.ts`.
+- Pattern: route-level `preHandler` guard plus request decoration (`backend/src/routes/settings.ts:138`, `backend/src/plugins/auth.ts:236`).
+
+**Notification Delivery Contract:**
+- Purpose: keep route-triggered and scheduler-triggered notifications consistent.
+- Examples: `backend/src/routes/planner.ts`, `backend/src/services/reminder-scheduler.ts`, `backend/src/services/notifications/delivery.ts`.
+- Pattern: shared builders/delivery/state helpers imported into both paths (`backend/src/routes/planner.ts:23`, `backend/src/services/reminder-scheduler.ts:39`).
+
+**Frontend App Context Aggregator:**
+- Purpose: centralize shared medication/settings/dose/share/refill state for page/modal consumers.
+- Examples: `frontend/src/context/AppContext.tsx`, `frontend/src/context/ShareContext.tsx`.
+- Pattern: compose domain hooks, expose typed value via provider (`frontend/src/context/AppContext.tsx:248`, `frontend/src/context/AppContext.tsx:1020`).
+
+## Entry Points
+
+**Frontend bootstrap:**
+- Location: `frontend/src/main.tsx`
+- Triggers: browser loads `index.html`.
+- Responsibilities: initialize theme/provider stack and router (`frontend/src/main.tsx:12`, `frontend/src/main.tsx:15`).
+
+**Backend process entry:**
+- Location: `backend/src/index.ts`
+- Triggers: `npm run dev`/`npm start` in backend package.
+- Responsibilities: await migrations, register routes, start HTTP listener and schedulers (`backend/src/index.ts:231`, `backend/src/index.ts:305`, `backend/src/index.ts:309`, `backend/src/index.ts:334`).
+
+## Architectural Constraints
+
+- **Threading:** Single Node.js event loop process with in-process schedulers started at runtime (`backend/src/index.ts:309`, `backend/src/index.ts:323`).
+- **Global state:** Module/global singletons exist in auth and context layers (`backend/src/plugins/auth.ts:15`, `frontend/src/context/AppContext.tsx:222`).
+- **Circular imports:** Not detected from sampled route/service/db/frontend orchestration files.
+- **API boundary:** Frontend network calls must use `/api/*` so proxy rewrite applies (`frontend/vite.config.ts:23`, `frontend/vite.config.ts:26`).
+
+## Anti-Patterns
+
+### Duplicated Backend App Wiring
+
+**What happens:** Route/plugin registration appears in both `createApp(...)` and top-level startup path.
+**Why it's wrong:** Two bootstrap paths increase divergence risk when new routes/plugins are added in one path but not the other.
+**Do this instead:** Keep a single shared app-construction function used by both test/runtime startup paths (`backend/src/index.ts:133`, `backend/src/index.ts:207`, `backend/src/index.ts:289`).
+
+### Oversized Frontend Orchestration Context
+
+**What happens:** `AppContext` aggregates many unrelated concerns (medications, settings, doses, sharing, import/export, modal history) in one large provider.
+**Why it's wrong:** High coupling and broad rerender surface make safe changes harder and increase regression risk.
+**Do this instead:** Preserve existing provider contract, but move new domain concerns into focused hooks/providers and re-export through composition only when needed (`frontend/src/context/AppContext.tsx`, file size ~1035 lines).
+
+## Error Handling
+
+**Strategy:** Fail fast at route boundary with explicit status codes and schema validation, then log context-rich errors.
+
+**Patterns:**
+- Route validation + immediate 400 responses for invalid input (`backend/src/routes/medications.ts:76`, `backend/src/routes/medications.ts:584`).
+- Planner routes return explicit channel/config errors (`backend/src/routes/planner.ts:204`, `backend/src/routes/planner.ts:509`).
+- Frontend captures network errors and maps them to normalized error codes for UI handling (`frontend/src/hooks/useMedications.ts:80`).
+
+## Cross-Cutting Concerns
+
+**Logging:** Fastify logger options configured centrally with environment-aware formatting (`backend/src/index.ts:66`, `backend/src/index.ts:161`).
+**Validation:** Zod validation for medication payloads and explicit OpenAPI schema contracts in routes (`backend/src/routes/medications.ts:76`, `backend/src/routes/planner.ts:157`).
+**Authentication:** Route-level auth hooks and dual API-key/session handling (`backend/src/routes/planner.ts:141`, `backend/src/plugins/auth.ts:113`, `backend/src/plugins/auth.ts:236`).

+- Issue: `backend/src/index.ts` contains two parallel server setup paths (the exported `createApp(...)` flow and the top-level runtime bootstrap). Plugin/route registration and rate-limit defaults are duplicated in both branches.
+- Files: `backend/src/index.ts`
+- Impact: Configuration behavior can diverge between test/programmatic app construction and production startup (for example, `createApp` uses fixed `rateLimit` max `300`, while runtime startup uses `process.env.RATE_LIMIT_MAX` fallback `100`).
+- Fix approach: Extract one canonical app-construction function and let both runtime startup and tests consume it; remove duplicated registration blocks.
+
+**Notification architecture leakage and duplicated composition logic:**
+- Issue: Notification delivery service code imports a route-layer helper (`sendShoutrrrNotification`) from settings routes, and large HTML/text reminder composition blocks are duplicated across manual and automatic reminder paths.
+- Files: `backend/src/services/notifications/delivery.ts`, `backend/src/routes/settings.ts`, `backend/src/routes/planner.ts`, `backend/src/services/reminder-scheduler.ts`
+- Impact: Layer boundary violations increase coupling, and duplicated notification formatting logic makes behavior regressions likely when changing message content or channel behavior.
+- Fix approach: Move `sendShoutrrrNotification` to a service-layer module, make routes call service APIs only, and centralize email/push payload builders for planner + scheduler flows.
+
+**Migration artifact ambiguity in drizzle numbering:**
+- Issue: There are two migration files with `0008_` prefix, but the journal tracks only one `0008` tag and then jumps to `0009`.
+- Files: `backend/drizzle/0008_add_obsolete_medications.sql`, `backend/drizzle/0008_add_prescription_tracking.sql`, `backend/drizzle/meta/_journal.json`
+- Impact: Developer confusion and higher risk of migration-order mistakes during future schema changes.
+- Fix approach: Align migration file names and journal tags so each migration number is unique and journal order is obvious.
+
+**Monolithic UI/editor and route modules with broad lint suppressions:**
+- Issue: Core interaction files are very large and rely on file-level `biome-ignore-all` suppressions for multiple rule categories.
+- Files: `frontend/src/pages/MedicationsPage.tsx`, `frontend/src/components/MobileEditModal.tsx`, `frontend/src/components/SharedSchedule.tsx`, `frontend/src/components/MedDetailModal.tsx`, `backend/src/routes/medications.ts`
+- Impact: Refactors become high-risk; local regressions are harder to isolate; suppressed rule categories hide legitimate quality issues in future edits.
+- Fix approach: Split by domain slices (state orchestration vs rendering vs helper transforms), then replace file-level suppressions with narrow, local exceptions only where justified.
+
+## Known Bugs
+
+**Environment-dependent behavior mismatch between test app factory and runtime app:**
+- Symptoms: Programmatic app creation and runtime startup can apply different operational defaults (rate limiting and selected config pathways).
+- Files: `backend/src/index.ts`
+- Trigger: Using `createApp(...)` in tests/integration contexts while production startup uses the top-level runtime branch.
+- Workaround: Explicitly pass runtime-equivalent options into `createApp(...)` in tests until startup construction is unified.
+
+## Security Considerations
+
+**Server-side outbound notification surface is broad and sensitive to parser correctness:**
+- Risk: The app performs server-side HTTP requests to user-configurable notification URLs, including multiple protocol handlers (`pushover://`, `telegram://`, `gotify://`, generic webhook URLs).
+- Files: `backend/src/routes/settings.ts`
+- Current mitigation: URL sanitation/validation and hostname checks are present (`sanitizeNotificationUrl`, `validateNotificationHostname` usage in route logic).
+- Recommendations: Add focused security regression tests for sanitizer bypasses and callback URL edge cases, and keep all outbound request execution in a dedicated service layer.
+
+**Auth-off bootstrap path creates implicit default user state:**
+- Risk: In auth-disabled mode, startup creates/relies on a default user path automatically.
+- Files: `backend/src/db/client.ts`
+- Current mitigation: Controlled by `AUTH_ENABLED` environment setting.
+- Recommendations: Add startup log warnings when running without auth outside development and enforce explicit environment confirmation in deployment templates.
+
+## Performance Bottlenecks
+
+**Reminder scheduling uses repeated full scans over users and medication/dose datasets:**
+- Problem: Reminder checks iterate all user settings and compute stock/prescription reminders with repeated in-memory loops over medication and dose collections.
+- Files: `backend/src/services/reminder-scheduler.ts`, `backend/src/utils/scheduler-utils.ts`
+- Cause: Polling/check strategy prioritizes correctness and compatibility over incremental indexing.
+- Improvement path: Introduce incremental candidate selection (changed-medication windows, per-user next-check indices) and reduce repeated whole-set scans.
+
+**Intake reminder scheduler polls every minute and may scale linearly with active schedules:**
+- Problem: Intake reminder check loop runs continuously at 60s interval and processes all due reminders/users each tick.
+- Files: `backend/src/services/intake-reminder-scheduler.ts`
+- Cause: Fixed-interval scheduler (`CHECK_INTERVAL_MS = 60 * 1000`) with loop-driven due-item selection.
+- Improvement path: Move toward next-due-time scheduling or bucketing strategy; keep minute polling as fallback only.
+
+## Fragile Areas
+
+**Reminder state persistence and lock handling mix sync file IO with best-effort catches:**
+- Files: `backend/src/services/notifications/state.ts`, `backend/src/services/reminder-scheduler.ts`
+- Why fragile: Reminder state writes are synchronous file writes and some read paths swallow errors (`catch {}`), while lock/state files are local filesystem coordination primitives.
+- Safe modification: Keep file format backward-compatible, add explicit error telemetry, and add tests for concurrent/failed write scenarios before changing scheduler state logic.
+- Test coverage: No direct tests detected for `notifications/delivery.ts` and only limited direct state-function assertions.
+
+**Desktop/mobile medication edit parity depends on two large independent UI paths:**
+- Files: `frontend/src/pages/MedicationsPage.tsx`, `frontend/src/components/MobileEditModal.tsx`, `frontend/src/components/medications/MedicationEditCoordinator.tsx`
+- Why fragile: The same editing domain is implemented in separate surfaces, each with dense UI logic and custom interaction handling.
+- Safe modification: Apply shared form-section components first, then update desktop and mobile in the same change; validate both paths with targeted tests.
+- Test coverage: Coverage exists (`MedicationEditCoordinator`, `MobileEditModal`, `MedicationDialogs` tests), but parity regressions remain a recurring risk due to file size/complexity.
+
+## Scaling Limits
+
+**Current reminder architecture is single-node/local-state oriented:**
+- Current capacity: Scheduler state and lock coordination are local files under data directory (`reminder-state.json`, `scheduler-locks/*`).
+- Limit: Horizontal multi-instance scaling can duplicate work or require externalized coordination.
+- Scaling path: Move reminder state/locks to DB or distributed lock backend and make scheduler execution leader-aware.
+
+**SQLite file-backed persistence constrains concurrent write scaling:**
+- Current capacity: Single SQLite file with local filesystem path resolution.
+- Limit: Higher write concurrency and distributed deployments will hit filesystem/database locking and throughput limits.
+- Scaling path: Keep SQLite for local/small deployments; define migration path to managed DB for larger multi-user workloads.
+
+## Dependencies at Risk
+
+**Route-to-service coupling in notification stack:**
+- Risk: Service-layer delivery module depends on route-layer helper import.
+- Impact: Refactors of route modules can break unrelated notification infrastructure and complicate testing boundaries.
+- Migration plan: Move shared notification send helpers into `backend/src/services/notifications/*` and keep route modules thin.
+
+## Missing Critical Features
+
+**Risk-driven scheduler stress/integration test suite for state-lock edge cases:**
+- Problem: Complex scheduler/state code paths rely on file coordination and mixed channel delivery outcomes, but dedicated stress/chaos-style verification is limited.
+- Blocks: High-confidence scaling and reliability changes in reminder subsystems.
+
+## Test Coverage Gaps
+
+**Notification delivery abstraction lacks direct unit tests:**
+- What's not tested: Direct behavior of SMTP transport creation/result validation and push delivery helpers in the dedicated delivery module.
+- Files: `backend/src/services/notifications/delivery.ts`
+- Risk: Regressions in recipient validation, SMTP response handling, or provider fallback can ship unnoticed.
+- Priority: High
+
+**Reminder state persistence/locking has limited direct verification:**
+- What's not tested: Corrupted file recovery, concurrent state writes, and lock stale-file behavior under failure modes.
+- Files: `backend/src/services/notifications/state.ts`, `backend/src/services/reminder-scheduler.ts`
+- Risk: Duplicate sends or missed sends after crashes/restarts are difficult to detect early.
+- Priority: High

+# Coding Conventions
+
+**Analysis Date:** 2026-04-30
+
+## Naming Patterns
+
+**Files:**
+- Frontend React components and pages use PascalCase file names (for example `frontend/src/components/MobileEditModal.tsx`, `frontend/src/pages/MedicationsPage.tsx`).
+- Hooks use `useX` camelCase naming in files and symbols (for example `frontend/src/hooks/useMedications.ts`, `frontend/src/hooks/useScheduleController.ts`).
+- Backend routes/services use kebab-case file names with domain suffixes (for example `backend/src/routes/medications.ts`, `backend/src/services/medications-service.ts`).
+- Test files use `*.test.ts` or `*.test.tsx` in dedicated test folders (for example `backend/src/test/planner.test.ts`, `frontend/src/test/components/MobileEditModal.test.tsx`).
+
+**Functions:**
+- Use camelCase names for functions and methods (for example `parseIntakesWithUnits` in `backend/src/services/medications-service.ts`, `loadMeds` in `frontend/src/hooks/useMedications.ts`).
+- Use verb-first names for side-effect operations (`loadMeds`, `deleteMed`, `uploadMedImage` in `frontend/src/hooks/useMedications.ts`).
+
+**Variables:**
+- Use camelCase for local variables and state (`refillHistoryExpanded`, `scheduleDays`, `showFutureDays` in `frontend/src/context/AppContext.tsx`).
+- Constant maps and singleton keys use UPPER_SNAKE_CASE (`LOG_LEVELS` in `backend/src/utils/logger.ts`, `APP_CONTEXT_SINGLETON_KEY` in `frontend/src/context/AppContext.tsx`).
+
+**Types:**
+- Type aliases and interfaces use PascalCase (`AppContextValue` in `frontend/src/context/AppContext.tsx`, `TestContext` in `backend/src/test/setup.ts`).
+- Return-shape interfaces use `UseXReturn` convention for hooks (`UseMedicationsReturn` in `frontend/src/hooks/useMedications.ts`).
+
+## Code Style
+
+**Formatting:**
+- Tool used: Biome (`biome.json`, scripts in `frontend/package.json`, `backend/package.json`, `package.json`).
+- Key settings from `biome.json`:
+  - `indentStyle: tab`
+  - `indentWidth: 2`
+  - `lineWidth: 120`
+  - JavaScript quote style is double quotes, semicolons enabled, trailing commas `es5`.
+
+**Linting:**
+- Tool used: Biome linter (`biome.json`).
+- Key rules enforced/relevant:
+  - `style.useConst: error`
+  - `style.noNestedTernary: warn`
+  - `correctness.noUnusedVariables: warn`
+  - `suspicious.noExplicitAny: warn`
+- Project governance in `AGENTS.md` reinforces readable code, early returns, and no nested ternaries.
+
+## Import Organization
+
+**Order:**
+1. Node built-ins first in backend modules (for example `node:path` in `backend/src/routes/medications.ts`, `node:crypto` in `backend/src/index.ts`).
+2. External packages second (`fastify`, `zod`, `drizzle-orm` in backend; `react`, `@testing-library/*` in frontend).
+3. Internal modules last with relative paths (`../db/client.js`, `../../types`).
+
+**Path Aliases:**
+- Not detected in TypeScript configs (`frontend/tsconfig.json`, `backend/tsconfig.json` do not define `paths`).
+- Relative imports are the standard.
+
+## Error Handling
+
+**Patterns:**
+- Backend validates request data with Zod schemas and `.refine(...)` constraints before route logic (`backend/src/routes/medications.ts`).
+- Backend route tests assert explicit status codes and body shape (`backend/src/test/routes-real.test.ts`, `backend/src/test/planner.test.ts`).
+- Frontend hooks often normalize recoverable API errors into UI-safe states (`frontend/src/hooks/useMedications.ts` converts network failures into `NETWORK_ERROR`).
+- Some frontend fetch flows still use tolerant fallbacks (`catch(() => setMeds([]))` in `frontend/src/hooks/useMedications.ts`), so future changes should prefer explicit user-facing error channels per `AGENTS.md` fail-clear guidance.
+
+## Logging
+
+**Framework:**
+- Backend startup logger wrapper over console with level filtering in `backend/src/utils/logger.ts`.
+- Runtime HTTP logging via Fastify logger options in `backend/src/index.ts` (`buildLoggerOptions`, request correlation IDs).
+- Frontend logging utility mirrors backend level semantics (`frontend/src/utils/logger.ts`).
+
+**Patterns:**
+- Central log-level maps (`LOG_LEVELS`) and `shouldLog` gating are standard in both frontend and backend logger modules.
+- Correlation ID propagation is enforced at request boundaries (`backend/src/index.ts` onRequest hook setting `x-correlation-id`).
+
+## Comments
+
+**When to Comment:**
+- Comments are used for rationale and test setup intent, not line-by-line narration.
+- Typical examples:
+  - Migration/setup intent in `backend/src/test/setup.ts`
+  - E2E stability rationale in `frontend/e2e/fixtures/index.ts`
+  - Timeout/determinism notes in `frontend/vitest.config.ts` and `frontend/playwright.base.config.ts`
+
+**JSDoc/TSDoc:**
+- Used selectively for exported utilities and test helpers (`backend/src/test/setup.ts`, `frontend/e2e/fixtures/index.ts`, `frontend/src/utils/logger.ts`).
+- Not mandatory for every function; concise type annotations plus targeted comments are preferred.
+
+## Function Design
+
+**Size:**
+- Small-to-medium focused functions are common in services/hooks (`parseRawIntakeUnits`, `normalizeDateTime` in `backend/src/services/medications-service.ts`).
+- Larger orchestrator modules exist where domain aggregation is required (`frontend/src/context/AppContext.tsx`).
+
+**Parameters:**
+- Object parameters are used for extensibility in test factories and route payload shapes (`CreateMedicationOptions` in `backend/src/test/setup.ts`).
+- Explicit primitive parameters used for concise helpers (`clickEditMed(page, medName)` in `frontend/e2e/medication-edit.spec.ts`).
+
+**Return Values:**
+- Explicit return types are common on exported functions (`Promise<TestContext>`, `UseMedicationsReturn`).
+- Guard-clause returns are common for invalid input or unavailable state (`if (!intakesJson) return [];` in `backend/src/services/medications-service.ts`).
+
+## Module Design
+
+**Exports:**
+- Named exports are preferred for utilities, hooks, and service functions (`backend/src/services/notifications/index.ts`, `frontend/src/hooks/index.ts`).
+- Mixed export style is used where legacy/default exports remain practical (`default` exports in component barrel `frontend/src/components/index.ts`).
+
+**Barrel Files:**
+- Barrel files are actively used for stable import surfaces:
+  - `frontend/src/components/index.ts`
+  - `frontend/src/hooks/index.ts`
+  - `backend/src/services/notifications/index.ts`
+- Practical rule for new code: export domain-level public APIs through local barrels, keep deep internal helpers imported directly.

+- `backend/vitest.config.ts`: Backend unit/integration test config.
+- `backend/drizzle.config.ts`: Drizzle migration configuration.
+- `.gitignore`: Local-only/generated path policy (including `.planning/`, `doku/`, `data/`, coverage/test artifacts).
+
+**Core Logic:**
+- `backend/src/routes/`: API contracts and request handlers.
+- `backend/src/services/`: Scheduler, notifications, medication helpers.
+- `backend/src/db/schema.ts`: Source-of-truth table definitions.

+
+## Naming Conventions
+
+**Files:**
+- React components/pages use PascalCase: `frontend/src/pages/MedicationsPage.tsx`, `frontend/src/components/MedDetailModal.tsx`.
+- Hooks use `use*` naming: `frontend/src/hooks/useMedications.ts`, `frontend/src/hooks/useSettings.ts`.
+- Backend routes/services use kebab-case: `backend/src/routes/medication-enrichment.ts`, `backend/src/services/reminder-scheduler.ts`.

+
+**Directories:**
+- Feature/layer folders are lowercase: `frontend/src/context`, `backend/src/services`.
+- Test directories stay colocated by runtime side (`frontend/src/test`, `backend/src/test`).
+
+## Where to Add New Code
+
+**New Feature:**
+- Primary code:
+  - Frontend UI route/screen: `frontend/src/pages/` (compose from existing `components/`, `hooks/`, `ui/`).
+  - Backend endpoint: `backend/src/routes/` + matching domain logic in `backend/src/services/`.
+  - Persistence additions: `backend/src/db/schema.ts` plus migration updates in `backend/src/db/client.ts` and `backend/drizzle/`.
+- Tests:
+  - Frontend unit/component: `frontend/src/test/`.
+  - Backend unit/integration: `backend/src/test/`.
+  - E2E flow: `frontend/e2e/`.
+
+**New Component/Module:**
+- Implementation:
+  - Shared UI primitive/layout: `frontend/src/ui/`.
+  - Domain-specific UI component: `frontend/src/components/` (or nested feature folder).
+  - Backend reusable domain behavior: `backend/src/services/`.
+
+**Utilities:**
+- Shared helpers:
+  - Frontend: `frontend/src/utils/`.
+  - Backend: `backend/src/utils/`.
+  - DB-specific helpers: `backend/src/db/` focused utility modules.

+# Testing Patterns
+
+**Analysis Date:** 2026-04-30
+
+## Test Framework
+
+**Runner:**
+- Vitest 4.x for unit/integration tests in both packages:
+  - Frontend config: `frontend/vitest.config.ts`
+  - Backend config: `backend/vitest.config.ts`
+- Config evidence:
+  - Frontend uses `environment: 'jsdom'` with React setup file `frontend/src/test/setup.ts`.
+  - Backend uses `environment: 'node'` with setup file `backend/src/test/setup.ts`.
+
+**Assertion Library:**
+- Vitest `expect`.
+- Frontend extends DOM assertions via `@testing-library/jest-dom` in `frontend/src/test/setup.ts`.
+
+**Run Commands:**
+```bash
+cd frontend && npm test                 # Watch/unit tests
+cd frontend && npm run test:run         # CI-style frontend run
+cd frontend && npm run test:coverage    # Frontend coverage
+cd backend && npm test                  # Watch/unit tests
+cd backend && npm run test:run          # CI-style backend run
+cd backend && npm run test:coverage     # Backend coverage
+cd frontend && npm run test:e2e         # Stable Playwright suite
+cd frontend && npm run test:e2e:all     # Cross-browser Playwright suite
+```
+
+## Test File Organization
+
+**Location:**
+- Backend unit/integration tests are in `backend/src/test/*.test.ts`.
+- Frontend unit/component/hook/context tests are in `frontend/src/test/**`.
+- Browser E2E tests are in `frontend/e2e/*.spec.ts`.
+
+**Naming:**
+- Unit/integration: `*.test.ts` or `*.test.tsx` (for example `backend/src/test/routes-real.test.ts`, `frontend/src/test/components/MedicationDialogs.test.tsx`).
+- E2E: `*.spec.ts` (for example `frontend/e2e/medication-edit.spec.ts`).
+
+**Structure:**
+```
+backend/src/test/
+  setup.ts
+  *.test.ts
+
+frontend/src/test/
+  setup.ts
+  App.test.tsx
+  components/*.test.tsx
+  context/*.test.tsx
+  hooks/*.test.ts
+  pages/*.test.tsx
+  utils/*.test.ts
+
+frontend/e2e/
+  auth.setup.ts
+  fixtures/index.ts
+  *.spec.ts
+```
+
+## Test Structure
+
+**Suite Organization:**
+```typescript
+describe("Feature Area", () => {
+  beforeEach(() => {
+    vi.clearAllMocks();
+  });
+
+  it("handles expected behavior", async () => {
+    // arrange
+    // act
+    // assert
+    expect(result).toEqual(expected);
+  });
+});
+```
+Pattern evidence: `frontend/src/test/components/MobileEditModal.test.tsx`, `backend/src/test/planner.test.ts`.
+
+**Patterns:**
+- Setup pattern:
+  - Frontend centralizes browser mocks in `frontend/src/test/setup.ts` (fetch, localStorage, clipboard, history, i18n).
+  - Backend provides reusable app/database factories in `backend/src/test/setup.ts` (`buildTestApp`, `createTestUser`, `createTestMedication`).
+- Teardown pattern:
+  - `afterAll` closes Fastify app and DB clients (`backend/src/test/planner.test.ts`, `backend/src/test/integration.test.ts`).
+- Assertion pattern:
+  - Route tests assert both HTTP status and response body (`backend/src/test/routes-real.test.ts`).
+  - UI tests assert presence and behavior via Testing Library role/test-id queries (`frontend/src/test/components/MedicationDialogs.test.tsx`).
+
+## Mocking
+
+**Framework:**
+- Vitest mocks (`vi.mock`, `vi.fn`, `vi.hoisted`, `vi.stubGlobal`).
+
+**Patterns:**
+```typescript
+const { testClient, testDb } = vi.hoisted(() => {
+  const client = createClient({ url: ":memory:" });
+  const db = drizzle(client);
+  return { testClient: client, testDb: db };
+});
+
+vi.mock("../db/client.js", () => ({
+  db: testDb,
+  migrationsReady: Promise.resolve(),
+}));
+```
+Pattern evidence: `backend/src/test/integration.test.ts`, `backend/src/test/routes-real.test.ts`.
+
+```typescript
+vi.mock("../../components/ConfirmModal", () => ({
+  ConfirmModal: ({ onConfirm }) => <button onClick={onConfirm}>confirm</button>,
+}));
+```
+Pattern evidence: `frontend/src/test/components/MedicationDialogs.test.tsx`.
+
+**What to Mock:**
+- External side effects and infrastructure boundaries: SMTP/nodemailer, fetch network calls, auth/plugin env modules, browser APIs.
+- Component dependencies in focused unit tests (replace heavy children with stubs).
+
+**What NOT to Mock:**
+- Core business behavior under direct test (route handlers in route tests, hook logic in hook tests, E2E API + UI flow in Playwright).
+
+## Fixtures and Factories
+
+**Test Data:**
+```typescript
+const userId = await createTestUser(client, { username: "testuser" });
+const medId = await createTestMedication(client, { userId, name: "Test Medication" });
+```
+Pattern evidence: `backend/src/test/setup.ts`, used by `backend/src/test/medications.test.ts`.
+
+```typescript
+export const test = base.extend({
+  page: async ({ page }, use) => {
+    await applyVideoSafetyMode(page);
+    await setupAuthMeMock(page);
+    await use(page);
+  },
+});
+```
+Pattern evidence: `frontend/e2e/fixtures/index.ts`.
+
+**Location:**
+- Backend factories/utilities: `backend/src/test/setup.ts`.
+- Frontend E2E shared fixtures and API helpers: `frontend/e2e/fixtures/index.ts`.
+
+## Coverage
+
+**Requirements:**
+- Frontend global thresholds in `frontend/vitest.config.ts`: lines/functions/branches/statements = 75.
+- Backend global thresholds in `backend/vitest.config.ts`: lines 60, functions 65, branches 50, statements 60.
+
+**View Coverage:**
+```bash
+cd frontend && npm run test:coverage
+cd backend && npm run test:coverage
+```
+
+## Test Types
+
+**Unit Tests:**
+- Component/hook/utils tests in `frontend/src/test/**`.
+- Utility/service route-unit style tests in `backend/src/test/*.test.ts`.
+
+**Integration Tests:**
+- Backend route interaction and multi-route behavior tests in files like:
+  - `backend/src/test/integration.test.ts`
+  - `backend/src/test/routes-real.test.ts`
+
+**E2E Tests:**
+- Playwright used with setup project and browser projects (`frontend/playwright.base.config.ts`).
+- Auth/session and API seeding helpers in `frontend/e2e/fixtures/index.ts`.
+
+## Common Patterns
+
+**Async Testing:**
+```typescript
+await waitFor(() => {
+  expect(mockFn).toHaveBeenCalledTimes(1);
+});
+```
+Pattern evidence: `frontend/src/test/context/AppContext.test.tsx`.
+
+```typescript
+const response = await app.inject({ method: "GET", url: "/settings" });
+expect(response.statusCode).toBe(200);
+```
+Pattern evidence: `backend/src/test/routes-real.test.ts`.
+
+**Error Testing:**
+```typescript
+const response = await app.inject({ method: "POST", url: "/planner/send-email", payload: { rows: [] } });
+expect(response.statusCode).toBe(400);
+expect(response.json()).toEqual({ error: "Missing planner data" });
+```
+Pattern evidence: `backend/src/test/planner.test.ts`.

 | `PORT` | `3000` | Backend API port |
-| `CORS_ORIGINS` | `http://localhost:4174` | Allowed origins for CORS |
+| `CORS_ORIGINS` | `http://localhost:4174` | Allowed frontend origins |
-| `LOG_LEVEL` | `info` | Log verbosity (`debug`, `info`, `warn`, `error`, `silent`). At `info` (default), high-frequency polling endpoints are suppressed. Set `debug` to see all requests. |
+| `TZ` | `Europe/Berlin` | Default timezone for reminders |
-| `OPENAPI_DOCS_ENABLED` | `auto` | Enables API docs in non-production by default. Set explicitly to `true`/`false` to override. |
-| `TZ` | `Europe/Berlin` | Timezone for scheduled reminders |
 
-Recommended values for API docs by environment:
+Optional but commonly needed:
-
-| Environment | Recommendation |
-|-------------|----------------|
-| Development | `OPENAPI_DOCS_ENABLED=true` |
-| Staging/Test | `OPENAPI_DOCS_ENABLED=true` |
-| Production | leave it unset, or set `OPENAPI_DOCS_ENABLED=false` |
-
-Notes:
-
-- If `OPENAPI_DOCS_ENABLED` is not set, docs are enabled outside production and disabled in production.
-- If `OPENAPI_DOCS_ENABLED=true`, docs are available on `/docs` and `/docs/json`.
-- If `OPENAPI_DOCS_ENABLED=false`, only the docs are disabled. The API still works normally.
