+# CannaManage Sprint 5 Plan — Multi-Persona Review Panel
+
+**Date:** 2026-06-12
+**Reviewed Document:** `docs/sprint-5/cannamanage-sprint5-plan.md` (v2, ~840 lines)
+**Review Method:** 6-persona stakeholder simulation, scoring on 4 dimensions (0–100%)
+**Iteration:** 1
+
+---
+
+## v2 Decisions Incorporated
+
+The Sprint 5 plan v2 incorporates all Q&A decisions from the planning session:
+
+1. ✅ **@tanstack/react-query** — caching, refetch, optimistic updates (Q1)
+2. ✅ **Per-component loading** — independent card/table loading, no full-page blocking (Q2)
+3. ✅ **Stale-while-revalidate + "Offline" banner** — graceful degradation (Q3)
+4. ✅ **Full CRUD staff management** — list, invite, edit perms, revoke (Q4)
+5. ✅ **Dual seed data strategy** — SQL for dev/test + API-driven for system E2E (Q5)
+6. ✅ **Next.js 15.2.8 → 15.5.18 upgrade** — addresses 8+ Snyk CVEs in Phase 1 (Bonus)
+
+---
+
+## 1. 👤 Club Member (End User)
+
+*"I'm a regular member of a cannabis social club. I want to see my quota, pick up my cannabis, and check my history — now with real data instead of fake numbers."*
+
+### Findings
+
+| # | Type | Observation |
+|---|------|-------------|
+| 1 | ✅ Positive | **Real-time quota data** — my portal dashboard now shows actual usage from the database, not mock numbers. I can trust the "28g remaining" display because it's coming from the real backend with server-authoritative calculations. |
+| 2 | ✅ Positive | **Stale-while-revalidate** — if my phone briefly loses signal in the club, I still see my last-known quota instead of a blank page. The "Offline" banner is unobtrusive. |
+| 3 | ✅ Positive | **Per-component loading** — when I open the portal, I see my quota radial load first (fast), then history loads separately. No frozen full-page spinner. |
+| 4 | ✅ Positive | **Distribution history is live** — I can see a distribution appear in my history immediately after the staff records it. No manual refresh needed. |
+| 5 | ⚠️ Minor | **No push notification for distributions** — I still won't get notified when a distribution is recorded against my account. I have to check manually. (Acknowledged as Sprint 6+ scope.) |
+| 6 | ✅ Positive | **Portal auth is explicitly planned** — Phase 5 specifically calls out wiring the portal login flow with session-based auth. My separate login experience is preserved. |
+
+### Scores
+
+| Dimension | Score | Rationale |
+|-----------|-------|-----------|
+| Precision | 92% | Portal integration is explicitly scoped in Phase 5 with specific endpoint mappings (`/portal/dashboard`, `/portal/history`). Loading patterns and offline handling are precisely defined. |
+| Correctness | 94% | React Query's stale-while-revalidate behavior correctly serves cached data during network issues. Quota calculations remain server-authoritative. Session-based portal auth is appropriate for member-facing UI. |
+| Usability | 88% | Per-component loading and offline resilience significantly improve my experience. Only gap: no proactive notifications when distributions are recorded or quotas reset. |
+| Usefulness | 90% | The transition from mock to real data is exactly what I need — my portal becomes trustworthy and useful for tracking my actual consumption. |
+
+**Composite Score: 91%**
+
+### Remaining Gaps (minor, Sprint 6+)
+- Push/email notifications for distributions and quota resets
+- PWA manifest for mobile home-screen shortcut
+
+---
+
+## 2. 🏢 Club Owner / Vorstand (Business Owner)
+
+*"I run the Anbauvereinigung. I need staff management, real reports for the Behörde, and confidence that the system works end-to-end."*
+
+### Findings
+
+| # | Type | Observation |
+|---|------|-------------|
+| 1 | ✅ Positive | **Full CRUD staff management** — Phase 6 covers list, invite, edit permissions, revoke. All 8 granular permissions are specified. This is exactly what I need to delegate work to my team without giving everyone full access. |
+| 2 | ✅ Positive | **Real report downloads** — Phase 5 wires PDF/CSV report generation from actual database data. Monthly reports for the Behörde will contain real distribution records, not mock data. |
+| 3 | ✅ Positive | **System test harness** — Phase 7 proves the full stack works end-to-end with a deterministic test flow. This gives me confidence that deployments won't break critical workflows. |
+| 4 | ✅ Positive | **Docker Compose full stack** — I can run the entire system locally with one command for demos to my Vorstand or to show the Behörde during audits. |
+| 5 | ✅ Positive | **Seed data for dev/test** — the dual strategy (SQL + API-driven) means I can quickly spin up a realistic environment for training new staff. |
+| 6 | ⚠️ Minor | **Staff activity log deferred** — I can't yet see *what* actions my staff performed (who recorded which distribution). Deferred to Sprint 6. |
+| 7 | ⚠️ Minor | **Club settings UI still pending** — email whitelist, prevention officer limits, and other club-level configuration isn't in Sprint 5 scope. |
+| 8 | ✅ Positive | **Permission chips are color-coded** — the plan specifies visual badges per permission, making it easy to scan who has what access at a glance. |
+
+### Scores
+
+| Dimension | Score | Rationale |
+|-----------|-------|-----------|
+| Precision | 93% | Staff management is thoroughly specified: 8 named permissions, invite flow, pending status handling, revoke confirmation. API endpoints are concrete. |
+| Correctness | 91% | Permission model matches the existing `StaffPermission` enum in the backend. RBAC enforcement (403 for unauthorized) is explicitly tested. Report generation uses established PDF/CSV generation code. |
+| Usability | 85% | Full CRUD staff management covers my daily needs. Missing activity log means I can't audit staff behavior yet. Club settings require direct backend config. |
+| Usefulness | 92% | This sprint delivers the #1 missing piece: staff management. Combined with real reports and system tests, I can now operate the club with confidence. |
+
+**Composite Score: 90%**
+
+### Remaining Gaps (Sprint 6)
+- Staff activity log (who did what, when)
+- Club settings UI (email whitelist, prevention officer limits)
+
+---
+
+## 3. 💻 Developer (Technical Implementer)
+
+*"I'm the one building this. Is the integration architecture sound? Are dependencies clear? Is the testing strategy robust?"*
+
+### Findings
+
+| # | Type | Observation |
+|---|------|-------------|
+| 1 | ✅ Positive | **React Query architecture is well-designed** — two-layer client (server-side `apiServer()` + client-side `apiFetch()`) with Next.js rewrite proxy keeps auth tokens server-side. Clean separation of concerns. |
+| 2 | ✅ Positive | **Service hooks pattern is consistent** — every domain gets the same structure: `useQuery` for reads, `useMutation` with `invalidateQueries` for writes. Easy to replicate across 7 service files. |
+| 3 | ✅ Positive | **Next.js upgrade in Phase 1** — doing the security upgrade *before* integration work prevents debugging whether issues come from the upgrade or new code. Smart sequencing. |
+| 4 | ✅ Positive | **Docker Compose is production-like** — multi-stage Maven build, PostgreSQL health checks, proper service dependencies. Build cache optimization mentioned for developer experience. |
+| 5 | ✅ Positive | **Error handling is comprehensive** — API error → status-specific German toast message mapping is precisely defined (401/403/409/500). Offline detection returns "Verbindungsfehler" toast. |
+| 6 | ✅ Positive | **Dual test strategy preserved** — mock E2E tests (<30s) for rapid iteration, system tests (minutes) for full-stack confidence. Both have clear value and separate configs. |
+| 7 | ⚠️ Minor | **No API versioning strategy discussed** — if backend DTOs change, there's no contract test or OpenAPI schema validation to catch frontend/backend drift. Currently relies on manual verification during Phase 3. |
+| 8 | ✅ Positive | **Risk assessment is realistic** — acknowledges Docker build slowness, CORS container issues, Playwright startup flakiness, and provides concrete mitigations for each. |
+| 9 | ✅ Positive | **Seed data with `ON CONFLICT DO NOTHING`** — idempotent SQL ensures repeatable migrations don't fail on re-runs. Correct Flyway pattern. |
+| 10 | ⚠️ Minor | **Optimistic update complexity** — Phase 4 mentions optimistic updates for distributions, but doesn't detail rollback behavior when the backend rejects (e.g., quota exceeded after optimistic decrement). React Query's `onMutate`/`onError` rollback pattern should be specified. |
+
+### Scores
+
+| Dimension | Score | Rationale |
+|-----------|-------|-----------|
+| Precision | 91% | Code examples for every pattern (React Query, CORS, Docker, error handling, seeds). File paths are explicit. Only missing: optimistic update rollback detail. |
+| Correctness | 93% | Architecture decisions are technically sound. React Query + Next.js rewrite proxy is the established pattern. Docker multi-stage build is correct. Flyway repeatable migration is appropriate for seed data. |
+| Usability | 88% | Developer experience is considered: DevTools in dev, skeleton components pre-built, one-command Docker startup. Phase sequencing is logical. Slightly high effort estimate (10.5 days single worker) may compress. |
+| Usefulness | 92% | This plan is immediately actionable. Every phase has acceptance criteria checkboxes. Directory structure shows exact file placement. Minimal ambiguity in implementation order. |
+
+**Composite Score: 91%**
+
+### Remaining Gaps (nice-to-have)
+- OpenAPI contract tests or schema validation between frontend types and backend DTOs
+- Explicit optimistic update rollback pattern documentation
+
+---
+
+## 4. 🛡️ Compliance Officer (CanKG / BfArM Regulatory)
+
+*"I ensure the system meets CanKG regulatory requirements. Distribution records must be immutable, quotas enforced, and audit trails available."*
+
+### Findings
+
+| # | Type | Observation |
+|---|------|-------------|
+| 1 | ✅ Positive | **Quota enforcement is server-authoritative** — the plan explicitly routes quota checks through the backend (`GET /compliance/quota/{memberId}`), not client-side calculations. The 409 response for exceeded limits prevents frontend manipulation. |
+| 2 | ✅ Positive | **Under-21 differentiation preserved** — Phase 4 acceptance criteria explicitly states "Under-21 members see 30g monthly limit enforced." The reduced quota is backend-enforced. |
+| 3 | ✅ Positive | **System test validates compliance flow** — the test harness (Phase 7) includes a distribution → quota update verification step, proving the enforcement pipeline works end-to-end. |
+| 4 | ✅ Positive | **Real PDF reports for Behörde** — the monthly report is generated from actual database records via the established `PdfReportGenerator`. No more mock data in regulatory documents. |
+| 5 | ✅ Positive | **Staff permission model controls access** — only users with `RECORD_DISTRIBUTIONS` permission can create distributions. `MANAGE_COMPLIANCE` controls compliance dashboard access. Least-privilege principle applied. |
+| 6 | ⚠️ Minor | **No mention of distribution record immutability in Sprint 5** — Sprint 4 established audit trail and 🔒 indicators. Sprint 5 should confirm these survive the integration (i.e., the real backend enforces immutability, not just the frontend). |
+| 7 | ✅ Positive | **Seed data includes realistic compliance scenarios** — 5 members with varying ages (including one born 2005 = under-21), 3 batches with different strains. Good for testing age-based quota differentiation. |
+
+### Scores
+
+| Dimension | Score | Rationale |
+|-----------|-------|-----------|
+| Precision | 88% | Quota enforcement endpoints and error codes are precisely specified. Under-21 handling is explicit. Minor gap: immutability guarantee from backend not re-confirmed for Sprint 5. |
+| Correctness | 92% | Server-authoritative quota checks with 409 response is the correct enforcement pattern. Staff permissions align with CanKG operational requirements. Age calculation from `date_of_birth` in seed data is testable. |
+| Usability | 86% | Compliance officers benefit from real reports and system tests proving the workflow. Missing: no dedicated compliance dashboard enhancements in Sprint 5 (existing dashboard from Sprint 3 carries forward). |
+| Usefulness | 90% | The transition to real data makes compliance reporting meaningful. System tests provide regulatory confidence. Staff permissions enable proper access control documentation for Behörde audits. |
+
+**Composite Score: 89%**
+
+### Remaining Gaps (Sprint 6)
+- Explicit immutability confirmation at the API level (backend `@PreAuthorize` + DB trigger or soft-delete pattern)
+- Monthly report auto-sealing (cryptographic timestamp)
+- Compliance dashboard enhancements (violation alerts, trend charts)
+
+---
+
+## 5. 🔒 Security Auditor
+
+*"I review the system for security vulnerabilities. Authentication, authorization, data protection, and secure communication are my focus."*
+
+### Findings
+
+| # | Type | Observation |
+|---|------|-------------|
+| 1 | ✅ Positive | **Next.js upgrade 15.2.8 → 15.5.18** — proactively addresses 8+ known CVEs including SSRF, authentication bypass, and resource exhaustion. Doing this in Phase 1 before integration work is the correct priority. |
+| 2 | ✅ Positive | **JWT stays server-side** — the proxy architecture (`/api/backend/*` rewrite) means JWT tokens never touch the browser. Client-side fetches use `credentials: "include"` with session cookies only. Reduced token theft surface. |
+| 3 | ✅ Positive | **CORS configuration is restrictive** — only `localhost:3000` and `frontend:3000` (Docker) are whitelisted. `allowCredentials: true` with explicit origins (not `*`). `maxAge: 3600L` limits preflight cache. |
+| 4 | ✅ Positive | **Permission-based authorization** — 8 granular permissions with enforcement at API level (403 for insufficient permissions). Only ADMIN + MANAGE_STAFF holders can modify staff. Defense in depth. |
+| 5 | ✅ Positive | **Error messages don't leak internals** — the `useApiErrorHandler` maps status codes to generic German messages. No stack traces, no internal paths, no SQL errors exposed to the client. |
+| 6 | ⚠️ Minor | **Seed data contains plaintext password placeholders** — `$2a$10$...bcrypt...` in the SQL is obviously a placeholder, but the plan should note that real bcrypt hashes must be generated during implementation. Password `admin123` is acceptable for test-seed profile only. |
+| 7 | ✅ Positive | **Docker secrets in environment variables** — `JWT_SECRET` and `POSTGRES_PASSWORD` are in docker-compose with clear "change-in-prod" suffixes. The plan acknowledges these are dev-only values. |
+| 8 | ⚠️ Minor | **No rate limiting mentioned** — the API endpoints (especially `/auth/login`, `/staff/invite`) should have rate limiting to prevent brute-force attacks. Not Sprint 5 scope but worth noting. |
+| 9 | ✅ Positive | **Portal uses session auth (not JWT)** — member portal correctly uses a separate auth mechanism (session cookies + CSRF) appropriate for public-facing user interfaces. |
+| 10 | ✅ Positive | **System test validates auth flows** — the test harness logs in as both admin and member, confirming both auth paths work correctly and are isolated from each other. |
+
+### Scores
+
+| Dimension | Score | Rationale |
+|-----------|-------|-----------|
+| Precision | 90% | CORS config is exact (origins, methods, headers, maxAge). Auth architecture is clearly layered (server-side JWT, client-side session). Permission model is enumerated. |
+| Correctness | 92% | Next.js upgrade addresses real CVEs. Server-side token handling is the security best practice. CORS with explicit origins + credentials is correctly restrictive. bcrypt for passwords is appropriate. |
+| Usability | 87% | Security measures don't impede development (CORS allows localhost, DevTools in dev mode, test-seed profile for easy setup). Good security/DX balance. |
+| Usefulness | 91% | Proactive CVE remediation, server-side token architecture, and granular permissions provide a solid security foundation. Rate limiting and 2FA are reasonable Sprint 6+ deferrals. |
+
+**Composite Score: 90%**
+
+### Remaining Gaps (Sprint 6+)
+- Rate limiting on auth endpoints
+- 2FA (TOTP) for admin accounts
+- CSRF token handling for portal session auth (not explicitly mentioned)
+- Content Security Policy headers (carried forward from Sprint 4)
+
+---
+
+## 6. 🎨 UX Designer
+
+*"I focus on user experience, interaction design, accessibility, and visual consistency across the application."*
+
+### Findings
+
+| # | Type | Observation |
+|---|------|-------------|
+| 1 | ✅ Positive | **Per-component skeleton loaders** — the plan includes specific skeleton components (`skeleton-card.tsx`, `skeleton-table.tsx`) that show shimmer during loading. This is better than a full-page spinner — users see progressive content appear. |
+| 2 | ✅ Positive | **Offline banner is non-blocking** — "Stale-while-revalidate + banner" means users can still interact with cached data while the banner communicates status. No modal or blocking overlay. |
+| 3 | ✅ Positive | **Error states have retry actions** — `error-state.tsx` component includes a retry button. Users aren't stuck — they can attempt recovery without navigating away. |
+| 4 | ✅ Positive | **Permission chips are color-coded** — staff permissions displayed as visual badges make the permission grid scannable at a glance. Pattern is consistent with existing UI components (shadcn Badge). |
+| 5 | ✅ Positive | **i18n for staff management** — Phase 6 explicitly includes adding German + English strings. Language consistency maintained across the new feature. |
+| 6 | ⚠️ Minor | **No loading animation specification** — skeleton components are mentioned but no design tokens for shimmer timing, color, or animation duration. Should match existing shadcn skeleton defaults. |
+| 7 | ⚠️ Minor | **Optimistic update UX not detailed** — when a distribution is recorded optimistically, what does the user see? Immediate list update with a subtle "saving..." indicator? Or just instant appearance? The undo pattern for failed optimistic updates needs visual design. |
+| 8 | ✅ Positive | **Toast messages are in German** — error toasts use natural German ("Sitzung abgelaufen", "Kontingent überschritten", "Verbindungsfehler"). Consistent with the i18n-first approach from Sprint 4. |
+| 9 | ✅ Positive | **Staff invite dialog with checkboxes** — the permission editor uses checkbox grid (8 permissions), which is the appropriate control for multi-select binary options. Familiar pattern. |
+| 10 | ⚠️ Minor | **No empty state illustrations** — empty states get messages but no visual illustrations. Sprint 4 defined empty state messages; Sprint 5 should carry them forward with real API responses. |
+
+### Scores
+
+| Dimension | Score | Rationale |
+|-----------|-------|-----------|
+| Precision | 87% | Loading patterns (skeletons, error state, retry) are specified as components. Toast messages have exact copy. Minor gap: no animation timing or optimistic update visual feedback details. |
+| Correctness | 90% | Per-component loading is the UX best practice for data-heavy dashboards. Stale-while-revalidate preserves user context during connectivity issues. Checkbox grid for permissions is appropriate. |
+| Usability | 86% | Progressive loading, offline resilience, and German error messages create a polished experience. Gaps: optimistic update visual feedback and empty state illustrations not specified. |
+| Usefulness | 88% | The UX improvements make the transition from mock to real data transparent to users. Loading and error states prevent confusion. Staff management UI follows established patterns. |
+
+**Composite Score: 88%**
+
+### Remaining Gaps (nice-to-have)
+- Optimistic update visual feedback pattern (saving indicator, rollback animation)
+- Empty state illustrations (consistent with shadcn/ui style)
+- Loading animation design tokens (shimmer timing, colors)
+- Accessibility audit for new staff management components (focus management in dialogs)
+

+## Consolidated Improvement Suggestions (Non-Blocking)
+
+These are recommendations for implementation-time refinement, not plan revisions:
+
+| # | Category | Suggestion | Priority |
+|---|----------|------------|----------|
+| 1 | Technical | Add explicit optimistic update rollback pattern (React Query `onMutate`/`onError`) | Medium |
+| 2 | Security | Add rate limiting to `/auth/login` and `/staff/invite` endpoints | Medium |
+| 3 | Compliance | Re-confirm distribution immutability at API level (not just UI lock icons) | Medium |
+| 4 | UX | Define visual feedback for optimistic updates (saving indicator, error rollback) | Low |
+| 5 | Technical | Consider OpenAPI schema validation for frontend/backend DTO contract | Low |
+| 6 | UX | Carry forward empty state illustrations from Sprint 4 design system | Low |
+| 7 | Security | Document CSRF token handling for portal session auth | Low |
+
+---
+
+## Comparison with Sprint 4 Review
+
+| Metric | Sprint 4 (Iteration 1) | Sprint 4 (Iteration 2) | Sprint 5 (This Review) |
+|--------|------------------------|------------------------|------------------------|
+| Overall Score | 78% | 88% | **90%** |
+| Iterations Needed | 2 | — | **1** ✅ |
+| Blocking Gaps | 8 | 0 | **0** |
+| Non-Blocking Gaps | 5 | 3 | **7** (minor) |
+
+Sprint 5 plan achieves a higher first-pass score than Sprint 4's final iteration, demonstrating that learnings from the Sprint 4 review process were incorporated into the planning methodology. All non-blocking gaps are implementation-time refinements rather than plan-level deficiencies.

+# CannaManage — Sprint 5 Implementation Plan
+
+**Date:** 2026-06-12
+**Author:** Patrick Plate / Lumen (Planner)
+**Status:** Draft v2
+**Base Branch:** `main`
+**Sprint Branch:** `sprint/5-integration`
+**Sprint Goal:** Wire frontend to real backend — full-stack integration, Docker Compose test harness, staff management UI
+
+> **Sprint Structure:** Sprint 5 is split into two sub-sprints:
+> - **Sprint 5.a** — Phases 1–5: Full-stack integration (~7 days)
+> - **Sprint 5.b** — Phases 6–7: Staff management + system tests (~3 days)
+>
+> Both are delivered within Sprint 5, organized as sequential sub-sprints (~10 days total).
+
+---
+
+## 0. Decisions (Confirmed ✅)
+
+| # | Decision | Detail | Status |
+|---|----------|--------|--------|
+| D1 | API client library | **@tanstack/react-query** — caching, refetch, optimistic updates, loading/error states. Wraps the existing server-side `apiClient()` with client-side hooks. | ✅ Confirmed (Q1) |
+| D2 | Loading strategy | **Per-component loading** — each card/table loads independently with shimmer skeleton. No full-page blocking. | ✅ Confirmed (Q2) |
+| D3 | Offline resilience | **Stale-while-revalidate + "Offline" banner** — React Query serves stale cached data while attempting refetch. A persistent banner shows "Offline" status when backend is unreachable. No hard crash. | ✅ Confirmed (Q3) |
+| D4 | Staff UI scope | **Full CRUD** — list, invite, edit permissions, revoke. Activity log deferred to Sprint 6. | ✅ Confirmed (Q4) |
+| D5 | Seed data strategy | **SQL for dev/test** (Flyway repeatable migration `R__test_seed.sql` activated by Spring profile `test-seed`) + **API-driven for system E2E** (Playwright calls API to set up test state). Dual approach: deterministic SQL for fast local dev, API-driven for realistic integration coverage. | ✅ Confirmed (Q5) |
+| D6 | CORS approach | **Spring Boot `@CrossOrigin` + `CorsConfigurationSource` bean** — allows `localhost:3000` in dev, configurable per environment. Needed when running frontend outside Docker (dev mode). | ✅ Carried from v1 |
+| D7 | Docker profiles | Remove `profiles: [full]` from backend/frontend services → always-on. Add `docker-compose.test.yml` overlay for Playwright + seed data. | ✅ Carried from v1 |
+| D8 | Next.js upgrade | **Upgrade 15.2.8 → 15.5.18** in Phase 1. Addresses 8+ Snyk CVEs (SSRF, auth bypass, resource allocation). Performed early to surface breaking changes before integration work. | ✅ Confirmed (Bonus) |
+
+---
+
+## 1. Sprint 4 Recap (Context)
+
+| Delivered | Status |
+|-----------|--------|
+| Next.js 15 + shadcn/ui frontend (12 pages, 23K lines) | ✅ |
+| Admin dashboard with KPIs, chart, sidebar nav | ✅ |
+| Member management (TanStack Table, add/edit forms) | ✅ |
+| Distribution recording (multi-step form + quota check) | ✅ |
+| Stock/batch management (chart, recall, add batch) | ✅ |
+| Reports page (PDF/CSV download triggers) | ✅ |
+| Member portal (quota radial, history, profile) | ✅ |
+| i18n (de/en), dark+light mode, Docker multi-stage | ✅ |
+| Playwright E2E (66+ tests with mock backend) | ✅ |
+
+**Critical gap from Sprint 4:** Frontend uses local mock data (`src/data/mock/*`). No real API calls. Frontend and backend are completely disconnected.
+
+---
+
+## 2. Sprint 5 Scope
+
+### ✅ IN Scope — Sprint 5.a (Full-Stack Integration)
+
+| # | Feature | Priority | Effort |
+|---|---------|----------|--------|

+| 4 | **Wire distributions + stock** — real distribution recording with quota check | P0 | 1.5 days |
+| 5 | **Wire reports + portal** — real report downloads, portal dashboard with live data | P1 | 1.5 days |
+
+**Sprint 5.a effort:** ~6.5 days
+
+### ✅ IN Scope — Sprint 5.b (Staff UI + System Tests)
+
+| # | Feature | Priority | Effort |
+|---|---------|----------|--------|
+| 6 | **Staff management UI** — list, invite, permissions editor, revoke | P1 | 2 days |
+| 7 | **System test harness** — seed data, Docker Compose test profile, E2E against real stack | P1 | 2 days |
+
+**Sprint 5.b effort:** ~4 days
+
+**Total estimated effort:** ~10 days (single worker, sequential)
+
+### ❌ OUT of Scope (Sprint 6+)
+
+- WebSocket notifications (email + in-app)
+- Inspector read-only mode
+- DSGVO consent management UI
+- PWA manifest + service worker
+- Micro-interactions (Framer Motion)
+- Monthly report auto-sealing
+- Cryptographic hash chain
+- 2FA (TOTP)
+
+---
+
+## 3. Architecture Decisions
+
+### 3.1 CORS Configuration (Decision D6)
+
+The frontend runs on `localhost:3000` in dev, but the backend is on `localhost:8080`. While Next.js rewrites (`/api/backend/:path*`) avoid CORS for server-side calls, client-side fetches (React Query) go directly. We add a proper CORS bean:
+
+```java
+// SecurityConfig.java — add to existing configuration
+@Bean
+public CorsConfigurationSource corsConfigurationSource() {
+ CorsConfiguration config = new CorsConfiguration();
+ config.setAllowedOrigins(List.of(
+ "http://localhost:3000", // dev
+ "http://frontend:3000" // Docker network
+ ));
+ config.setAllowedMethods(List.of("GET", "POST", "PUT", "DELETE", "PATCH"));
+ config.setAllowedHeaders(List.of("*"));
+ config.setAllowCredentials(true);
+ config.setMaxAge(3600L);
+
+ UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
+ source.registerCorsConfiguration("/api/**", config);
+ return source;
+}
+```
+
+Apply to the API filter chain:
+```java
+http.cors(cors -> cors.configurationSource(corsConfigurationSource()))
+```
+
+### 3.2 TanStack React Query Setup (Decision D1)
+
+```typescript
+// src/lib/query-client.ts
+import { QueryClient } from "@tanstack/react-query"
+
+export const queryClient = new QueryClient({
+ defaultOptions: {
+ queries: {
+ staleTime: 30_000, // 30s before refetch
+ gcTime: 5 * 60_000, // 5min garbage collection
+ retry: 1, // retry once on failure
+ refetchOnWindowFocus: true,
+ },
+ },
+})
+```
+
+Provider setup in root layout:
+```typescript
+// app/[locale]/providers.tsx
+"use client"
+import { QueryClientProvider } from "@tanstack/react-query"
+import { queryClient } from "@/lib/query-client"
+
+export function Providers({ children }: { children: React.ReactNode }) {
+ return (
+
+ {children}
+
+ )
+}
+```
+
+### 3.3 API Client Architecture (Server + Client)
+
+Two layers — server-side for SSR/RSC, client-side for interactive pages:
+
+```typescript
+// src/lib/api-client.ts (SERVER-SIDE — used in Server Components + Route Handlers)
+import { auth } from "@/lib/auth"
+
+const BACKEND_BASE = process.env.BACKEND_URL || "http://localhost:8080"
+
+export async function apiServer(path: string, options: RequestInit = {}): Promise {
+ const session = await auth()
+ if (!session?.user) throw new Error("Unauthorized")
+
+ const res = await fetch(`${BACKEND_BASE}/api/v1${path}`, {
+ ...options,
+ headers: {
+ "Content-Type": "application/json",
+ Authorization: `Bearer ${session.accessToken}`,
+ ...options.headers,
+ },
+ next: { revalidate: 30 }, // ISR-style caching
+ })
+
+ if (!res.ok) {
+ const error = await res.json().catch(() => ({ message: res.statusText }))
+ throw new ApiError(res.status, error.message)
+ }
+ return res.json()
+}
+```
+
+```typescript
+// src/lib/api-client-browser.ts (CLIENT-SIDE — used with React Query hooks)
+export async function apiFetch(path: string, options: RequestInit = {}): Promise {
+ // Uses Next.js rewrite proxy → /api/backend/* → backend:8080/api/v1/*
+ const res = await fetch(`/api/backend${path}`, {
+ ...options,
+ headers: {
+ "Content-Type": "application/json",
+ ...options.headers,
+ },
+ credentials: "include", // sends session cookie for auth
+ })
+
+ if (!res.ok) {
+ const error = await res.json().catch(() => ({ message: res.statusText }))
+ throw new ApiError(res.status, error.message)
+ }
+ return res.json()
+}
+
+export class ApiError extends Error {
+ constructor(public status: number, message: string) {
+ super(message)
+ this.name = "ApiError"
+ }
+}
+```
+
+### 3.4 Service Hooks Pattern
+
+Each domain gets a service file with typed React Query hooks:
+
+```typescript
+// src/services/members.ts
+import { useQuery, useMutation, useQueryClient } from "@tanstack/react-query"
+import { apiFetch } from "@/lib/api-client-browser"
+import type { Member } from "@/types/api"
+
+export function useMembers() {
+ return useQuery({
+ queryKey: ["members"],
+ queryFn: () => apiFetch("/members"),
+ })
+}
+
+export function useMember(id: string) {
+ return useQuery({
+ queryKey: ["members", id],
+ queryFn: () => apiFetch(`/members/${id}`),
+ enabled: !!id,
+ })
+}
+
+export function useCreateMember() {
+ const queryClient = useQueryClient()
+ return useMutation({
+ mutationFn: (data: CreateMemberRequest) =>
+ apiFetch("/members", { method: "POST", body: JSON.stringify(data) }),
+ onSuccess: () => {
+ queryClient.invalidateQueries({ queryKey: ["members"] })
+ },
+ })
+}
+```
+
+### 3.5 Error Handling + Toast Pattern
+
+```typescript
+// src/hooks/use-api-error.ts
+import { useToast } from "@/hooks/use-toast"
+import { ApiError } from "@/lib/api-client-browser"
+
+export function useApiErrorHandler() {
+ const { toast } = useToast()
+
+ return (error: unknown) => {
+ if (error instanceof ApiError) {
+ switch (error.status) {
+ case 401:
+ toast({ title: "Sitzung abgelaufen", description: "Bitte erneut anmelden.", variant: "destructive" })
+ break
+ case 403:
+ toast({ title: "Zugriff verweigert", description: "Fehlende Berechtigung.", variant: "destructive" })
+ break
+ case 409:
+ toast({ title: "Kontingent überschritten", description: error.message, variant: "destructive" })
+ break
+ default:
+ toast({ title: "Fehler", description: error.message, variant: "destructive" })
+ }
+ } else {
+ toast({ title: "Verbindungsfehler", description: "Backend nicht erreichbar.", variant: "destructive" })
+ }
+ }
+}
+```
+
+### 3.6 Loading Skeleton Pattern
+
+```typescript
+// src/components/cannamanage/skeleton-card.tsx
+import { Skeleton } from "@/components/ui/skeleton"
+import { Card, CardContent, CardHeader } from "@/components/ui/card"
+
+export function SkeletonCard() {
+ return (
+
+
+
+
+
+
+
+
+
+ )
+}
+```
+
+### 3.7 Docker Compose — Full Stack (Decision D7)
+
+```yaml
+# docker-compose.yml (updated — no profile gates)
+version: '3.9'

+```
+
+### 3.11 Optimistic Update with Rollback (for Phase 4)
+
+When recording a distribution, we optimistically update the UI (instant feedback) but roll back if the server rejects (e.g., quota exceeded):
+
+```typescript
+// src/services/distributions.ts — optimistic mutation pattern
+export function useCreateDistribution() {
+ const queryClient = useQueryClient()
+
+ return useMutation({
+ mutationFn: (data: CreateDistributionRequest) =>
+ apiFetch("/distributions", { method: "POST", body: JSON.stringify(data) }),
+
+ // Optimistic update: immediately reflect in UI
+ onMutate: async (newDistribution) => {
+ await queryClient.cancelQueries({ queryKey: ["distributions"] })
+ const previous = queryClient.getQueryData(["distributions"])
+ queryClient.setQueryData(["distributions"], (old = []) => [
+ { ...newDistribution, id: "optimistic-temp", createdAt: new Date().toISOString() } as Distribution,
+ ...old,
+ ])
+ return { previous } // context for rollback
+ },
+
+ // Rollback on error
+ onError: (_err, _variables, context) => {
+ if (context?.previous) {
+ queryClient.setQueryData(["distributions"], context.previous)
+ }
+ },
+
+ // Always refetch after success or error to sync with server state
+ onSettled: () => {
+ queryClient.invalidateQueries({ queryKey: ["distributions"] })
+ queryClient.invalidateQueries({ queryKey: ["dashboard"] }) // refresh KPIs
+ },
+ })
+}
+```
+
+**Key points:**
+- `onMutate` saves the previous state and applies the optimistic change
+- `onError` restores the previous state if the server returns 409 (quota exceeded) or 500
+- `onSettled` always re-fetches the truth from the server regardless of success/failure
+- The toast handler (from Section 3.5) shows the specific error message ("Kontingent überschritten: noch 12g verfügbar")

+
+## 5. Implementation Phases
+
+### Phase 1: Docker Compose Full Stack + Next.js Upgrade (1 day)
+
+**Goal:** `docker compose up` brings up PostgreSQL + Spring Boot + Next.js, all healthy and communicating. Next.js upgraded to 15.5.18 for security.
+
+**Tasks:**
+1. **Next.js upgrade 15.2.8 → 15.5.18** — addresses 8+ Snyk CVEs (SSRF, auth bypass, resource exhaustion). Run `pnpm up next@15.5.18`, fix any breaking changes in `next.config.mjs`, verify all pages render.
+2. Remove `profiles: [full]` from backend/frontend in `docker-compose.yml`
+3. Add backend health check (curl actuator/health)
+4. Add frontend dependency on `backend: condition: service_healthy`
+5. Add NEXTAUTH environment variables to frontend service
+6. Create/update `cannamanage-api/Dockerfile` (multi-stage Maven build)
+7. Add CORS configuration to `SecurityConfig.java`
+8. Add rate limiting to auth endpoints — Bucket4j or Spring `@RateLimiter` on `/api/v1/auth/login` (max 5 attempts/min per IP) and `/api/v1/staff/invite` (max 10/hour per user). Prevents brute-force attacks.
+9. Verify: `docker compose up` → all 3 containers healthy → `curl http://localhost:8080/actuator/health` returns UP
+10. Run existing Playwright E2E suite to confirm no regressions from Next.js upgrade
+
+**Acceptance Criteria:**
+- [ ] Next.js upgraded to 15.5.18 — `pnpm list next` shows correct version
+- [ ] All 66+ existing Playwright E2E tests still pass after upgrade
+- [ ] `docker compose up` starts all 3 services without errors
+- [ ] Backend responds to `/actuator/health` within 30s of start
+- [ ] Frontend loads at `http://localhost:3000` and displays login page
+- [ ] CORS allows `localhost:3000` to call `localhost:8080/api/v1/auth/login`
+- [ ] No `profiles` gate — services start by default
+
+---
+
+### Phase 2: API Client Layer (1 day)
+
+**Goal:** Typed, reusable API layer with React Query for client-side data fetching.
+
+**Tasks:**
+1. `pnpm add @tanstack/react-query @tanstack/react-query-devtools`
+2. Create `src/lib/query-client.ts` with default options
+3. Create `src/lib/api-client-browser.ts` — client-side fetch via Next.js rewrite proxy
+4. Refactor existing `src/lib/api-client.ts` → rename to server-side usage (`apiServer()`)
+5. Create `src/app/[locale]/providers.tsx` with `QueryClientProvider`
+6. Wire providers into root layout
+7. Create `src/hooks/use-api-error.ts` — error → toast mapping
+8. Create service files: `src/services/dashboard.ts`, `members.ts`, `distributions.ts`, `stock.ts`, `reports.ts`, `portal.ts`
+9. Create skeleton components: `skeleton-card.tsx`, `skeleton-table.tsx`, `error-state.tsx`
+10. Add React Query DevTools (dev only)
+
+**Acceptance Criteria:**
+- [ ] `@tanstack/react-query` installed and provider mounted
+- [ ] `apiFetch()` calls go through `/api/backend/*` rewrite to Spring Boot
+- [ ] Each domain has typed React Query hooks (queryKey, queryFn, types)
+- [ ] Error handler shows German toast messages for 401/403/409/500
+- [ ] Skeleton components render during loading state
+- [ ] React Query DevTools visible in dev mode (bottom-left panel)
+
+---
+
+### Phase 3: Wire Dashboard + Members (1.5 days)
+
+**Goal:** Dashboard shows real KPIs from backend. Member list fetches from real API.
+
+**Tasks:**
+1. **Dashboard page** — Replace `mockClubStats` with `useClubStats()` hook → `GET /clubs/stats`
+2. **Dashboard recent distributions** — `useRecentDistributions()` → `GET /distributions?limit=5`
+3. **Dashboard stock chart** — `useStockSummary()` → `GET /stock/batches/summary`
+4. **Member list** — Replace `mockMembers` with `useMembers()` → `GET /members`
+5. **Member detail** — `useMember(id)` → `GET /members/{id}`
+6. **Add member form** — `useCreateMember()` → `POST /members`
+7. **Edit member form** — `useUpdateMember()` → `PUT /members/{id}`
+8. Add loading skeletons to dashboard KPI cards and member table
+9. Add error states with retry button
+10. Handle empty states (no members yet, no distributions today)
+
+**Backend adjustments needed:**
+- Add `GET /api/v1/clubs/stats` endpoint if not existing (or adapt `ClubController`)
+- Ensure `GET /api/v1/members` returns paginated response compatible with TanStack Table
+- Verify `GET /api/v1/distributions` supports `?limit=N` query param
+
+**Acceptance Criteria:**
+- [ ] Dashboard loads real data — KPI cards show numbers from DB
+- [ ] Member list shows real members from PostgreSQL
+- [ ] Add member form creates a real member (visible after page refresh)
+- [ ] Edit member form persists changes
+- [ ] Loading skeletons appear during fetch
+- [ ] Error state shows when backend is down (not a blank page)
+- [ ] Empty state message when no data exists
+- [ ] No mock data imports remain in dashboard or members pages
+
+---
+
+### Phase 4: Wire Distributions + Stock (1.5 days)
+
+**Goal:** Distribution recording hits real backend with quota enforcement. Stock management is live.
+
+**Tasks:**
+1. **Distribution list** — `useDistributions()` → `GET /distributions`
+2. **New distribution form** — `useCreateDistribution()` → `POST /distributions`
+3. **Quota check (real-time)** — `useQuotaCheck(memberId)` → `GET /compliance/quota/{memberId}`
+4. Wire member search in distribution form to `GET /members?search=...`
+5. Wire batch selection to `GET /stock/batches?status=AVAILABLE`
+6. **Stock/batch list** — `useBatches()` → `GET /stock/batches`
+7. **Add batch form** — `useCreateBatch()` → `POST /stock/batches`
+8. **Recall batch** — `useRecallBatch()` → `PUT /stock/batches/{id}/recall`
+9. Handle quota exceeded error (409) → show specific toast with remaining grams
+10. Optimistic update: after recording distribution, immediately update local cache
+
+**Key integration points:**
+- Distribution form must pass `batchId` + `memberId` + `amountGrams`
+- Backend returns `409 Conflict` with `QuotaExceededException` details when over limit
+- Stock chart re-fetches after batch creation or recall
+
+**Acceptance Criteria:**
+- [ ] Distribution recording persists to DB (verifiable via `GET /distributions`)
+- [ ] Quota check prevents over-limit distribution (shows remaining grams in error)
+- [ ] Under-21 members see 30g monthly limit enforced
+- [ ] Batch creation adds real stock (visible in stock page)
+- [ ] Batch recall changes status to RECALLED
+- [ ] Stock chart updates after mutations
+- [ ] No mock data imports remain in distributions or stock pages
+
+---
+
+### Phase 5: Wire Reports + Portal (1.5 days)
+
+**Goal:** Report downloads generate real PDFs. Member portal shows live personal data.
+
+**Tasks:**
+1. **Monthly report** — `useDownloadReport("monthly")` → `GET /reports/monthly?format=pdf`
+2. **Member list report** — `GET /reports/member-list?format=csv`
+3. **Recall report** — `GET /reports/recall?format=pdf`
+4. Handle binary download (PDF/CSV) — create blob URL, trigger download
+5. **Portal dashboard** — `usePortalDashboard()` → `GET /portal/dashboard`
+6. **Portal history** — `usePortalHistory()` → `GET /portal/history`
+7. Portal auth: wire session-based login (`/portal/login` form submit)
+8. Show real quota radial with live monthly usage percentage
+9. Add date range picker for report generation (month selector)
+
+**Special handling:**
+- Report endpoints return binary (PDF) or text (CSV), not JSON — fetch with `responseType: blob`
+- Portal uses session auth (not JWT) — different fetch pattern (cookies, CSRF token)
+- Portal API calls go to `/portal/*` endpoints, not `/api/v1/*`
+
+**Acceptance Criteria:**
+- [ ] PDF report downloads as file (opens in browser/downloads)
+- [ ] CSV report downloads correctly formatted
+- [ ] Portal login with member credentials works
+- [ ] Portal dashboard shows real quota (used/remaining from DB)
+- [ ] Portal distribution history shows actual past distributions
+- [ ] No mock data imports remain in reports or portal pages
+
+---
+
+### Phase 6: Staff Management UI (2 days)
+
+**Goal:** Admin can invite staff, configure permissions, and revoke access through the UI.
+
+**Tasks:**
+1. Create staff settings page at `/settings/staff`
+2. Add navigation entry in sidebar (under Settings section)
+3. **Staff list component** — table with name, email, permissions, status, actions
+4. **Invite dialog** — email input + permission checkboxes (8 granular permissions)
+5. **Permissions editor** — inline permission toggle grid per staff member
+6. **Revoke dialog** — confirmation dialog → `DELETE /staff/{id}`
+7. Wire to backend:
+ - `GET /api/v1/staff` → list staff
+ - `POST /api/v1/staff/invite` → send invite
+ - `PUT /api/v1/staff/{id}/permissions` → update permissions
+ - `DELETE /api/v1/staff/{id}` → revoke
+8. Show pending invites (status: PENDING) with resend option
+9. Add i18n strings for staff management (de.json + en.json)
+10. Permission chips: visual badges for each permission (color-coded)
+
+**Permissions (from backend `StaffPermission` enum):**
+- `MANAGE_MEMBERS` — add/edit/suspend members
+- `RECORD_DISTRIBUTIONS` — record cannabis distributions
+- `MANAGE_STOCK` — add batches, recall
+- `VIEW_REPORTS` — download reports
+- `MANAGE_CLUB_SETTINGS` — edit club configuration
+- `MANAGE_COMPLIANCE` — compliance dashboard access
+- `INVITE_STAFF` — can invite other staff
+- `MANAGE_STAFF` — full staff CRUD (admin-like)
+
+**Acceptance Criteria:**
+- [ ] Staff list page accessible from sidebar navigation
+- [ ] Invite form sends email invite (or shows success if email service is stubbed)
+- [ ] Permission editor shows 8 checkboxes per staff member
+- [ ] Saving permissions persists to DB
+- [ ] Revoke removes staff access (deleted from list)
+- [ ] Pending invites shown with "Resend" action
+- [ ] Only ADMIN role can access staff settings (403 for STAFF role without MANAGE_STAFF)
+- [ ] i18n: all labels in both German and English
+
+---
+
+### Phase 7: System Test Harness (2 days)
+
+**Goal:** One command runs the full stack with seed data and executes E2E tests against real backend.
+
+**Tasks:**
+1. Create `R__test_seed.sql` — repeatable Flyway migration with deterministic test data
+2. Configure Spring profile `test-seed` to activate repeatable migration
+3. Create `docker-compose.test.yml` overlay (Playwright container + test-seed profile)
+4. Create `e2e/system-test.spec.ts` — full integration flow:
+ - Login as admin → verify dashboard loads with seed data
+ - Navigate to members → verify 5 seed members visible
+ - Add new member → verify appears in list
+ - Record distribution → verify quota updates
+ - Check stock decreases after distribution
+ - Download monthly report (verify PDF response)
+ - Login as member (portal) → verify personal quota visible
+5. Add npm script: `"test:system": "docker compose -f ... up --abort-on-container-exit"`
+6. Verify CI-readiness: exit code 0 on success, non-zero on failure
+7. Add GitHub Actions workflow stub (`.github/workflows/system-test.yml`)
+
+**Test flow (happy path):**
+```
+1. Admin login (admin@gruener-daumen.de / admin123)
+2. Dashboard → verify KPIs match seed data (5 members, 3 batches)
+3. Members → see "Max Müller", "Lisa Weber", etc.
+4. Add member "Test Neuzugang" → verify appears
+5. Distributions → record 10g Amnesia Haze to Max Müller
+6. Verify quota check shows updated usage
+7. Stock → verify Amnesia Haze batch decreased by 10g
+8. Reports → download monthly PDF → verify 200 response + content-type
+9. Portal login (max@example.com / member123)
+10. Portal dashboard → verify quota shows 10g used
+```
+
+**Acceptance Criteria:**
+- [ ] `docker compose -f docker-compose.yml -f docker-compose.test.yml up --abort-on-container-exit` runs full test
+- [ ] Seed data creates club + admin + staff + 5 members + 3 batches
+- [ ] System test covers: login → CRUD → quota → report → portal
+- [ ] Test passes in < 3 minutes on clean start
+- [ ] Exit code 0 on success, non-zero on any test failure
+- [ ] Test is deterministic (no flaky timing issues)
+- [ ] GitHub Actions workflow file created (can be enabled when GitHub repo is set up)
+

+
+## 6. Risk Assessment
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| Backend API mismatch (frontend expects fields that don't exist) | Medium | High | Read actual controller code before wiring; add DTO type assertions |
+| NextAuth session timeout during system test | Medium | Medium | Set long session expiry in test profile (24h) |
+| Docker build slow (Maven + Node rebuild each time) | High | Low | Use Docker build cache, `.dockerignore` excludes target/ |
+| CORS issues between containers | Medium | Medium | Test CORS early in Phase 1; add integration test for preflight |
+| React Query cache stale data after mutation | Low | Medium | Explicit `invalidateQueries` after every mutation |
+| Seed data conflicts with Hibernate DDL auto | Medium | High | Ensure `spring.jpa.hibernate.ddl-auto=validate` in Docker profile (Flyway handles schema) |
+| Playwright flaky on container startup timing | High | Medium | Add `waitForURL` + health check polling before test start |
+| Backend Dockerfile missing (never existed) | Medium | Low | Create from scratch in Phase 1 — straightforward multi-stage Maven |
+

+
+## 7. Open Questions — RESOLVED ✅
+
+All questions resolved in v2 planning session (2026-06-12):
+
+| # | Question | Decision | Rationale |
+|---|----------|----------|-----------|
+| Q1 | API client library? | ✅ **@tanstack/react-query** | Caching, refetch, optimistic updates built-in. Eliminates `useEffect` + `useState` boilerplate. DevTools for debugging. |
+| Q2 | Loading strategy? | ✅ **Per-component loading** | Each card/table loads independently — no full-page blocking. Better perceived performance. |
+| Q3 | Offline resilience? | ✅ **Stale-while-revalidate + "Offline" banner** | React Query serves cached data while retrying. Persistent banner communicates status without blocking interaction. |
+| Q4 | Staff UI scope? | ✅ **Full CRUD** (list + invite + edit perms + revoke) | Activity log deferred to Sprint 6. Full CRUD is the minimum viable staff management. |
+| Q5 | Seed data strategy? | ✅ **SQL for dev/test + API-driven for system E2E** | Dual approach: fast deterministic SQL seed for local dev, API-driven setup in system tests for realistic coverage. |
+| Q6 (Bonus) | Next.js upgrade? | ✅ **Yes — 15.2.8 → 15.5.18 in Phase 1** | Addresses 8+ Snyk CVEs. Done early to catch breaking changes before integration work begins. |
+
+Previously resolved (from v1):
+| # | Question | Decision |
+|---|----------|----------|
+| Q-v1-1 | Proxy vs direct CORS? | **Proxy** (Next.js rewrite) + CORS for dev flexibility |
+| Q-v1-2 | Activity log timing? | **Defer to Sprint 6** |
+| Q-v1-3 | System test config? | **Separate Playwright config** for Docker-based system tests |
+| Q-v1-4 | Keep mock data files? | **Yes** — fast E2E (<30s) coexists with system tests (minutes) |
+
+---
+
+## 8. Dependencies & Prerequisites
+
+| Prerequisite | Status | Action |
+|-------------|--------|--------|
+| Backend compiles and starts on current `main` | ✅ Done | Sprint 3 verified |
+| Backend `Dockerfile` exists | ❓ Check | Create in Phase 1 if missing |
+| Backend `actuator/health` endpoint enabled | ✅ Done | Spring Boot default |
+| Frontend `types/api.ts` matches backend DTOs | ⚠️ Partial | Verify during Phase 3; add missing types |
+| PostgreSQL 16 compatible with Hibernate schema | ✅ Done | Testcontainers use PG 16 |
+| `pnpm` and Node 22 available locally | ✅ Done | Sprint 4 verified |
+| Docker Desktop running | Required | Developer responsibility |
+
+---
+
+## 9. Success Metrics (End of Sprint 5)
+
+| Metric | Target |
+|--------|--------|
+| Pages using real API data | 12/12 (all pages, zero mock) |
+| Docker Compose startup → healthy | < 60 seconds |
+| System test pass rate | 100% (deterministic) |
+| System test duration | < 3 minutes |
+| API error handling coverage | 401, 403, 404, 409, 500 all handled |
+| Staff management operations | List, Invite, Edit Permissions, Revoke |
+| Remaining mock data files | Kept for fast E2E (not used in production pages) |

+
+## Execution Strategy
+
+### Fast feedback loop (during development):
+```bash
+# Frontend unit tests (Vitest — if configured)
+cd cannamanage-frontend && pnpm test
+
+# Backend integration tests (existing Testcontainers suite)
+cd cannamanage-api && mvn test
+
+# Existing Playwright E2E (mock backend, ~30s)
+cd cannamanage-frontend && pnpm exec playwright test
+```
+
+### Full system test (before merge):
+```bash
+docker compose -f docker-compose.yml -f docker-compose.test.yml up \
+ --build --abort-on-container-exit --exit-code-from playwright
+```
+
+### Manual smoke test checklist:
+1. `docker compose up` → all healthy
+2. Open http://localhost:3000 → login page
+3. Login as admin → dashboard with real data
+4. Add member → appears in list
+5. Record distribution → quota updates
+6. Download PDF report → valid file
+7. Login as member (portal) → see personal quota
