feat(sprint-3): Phase 1 — staff permissions + token revocation

- StaffPermission enum (8 granular permissions)
- StaffAccount JPA entity with permissions collection
- RevokedToken entity for JWT blacklisting
- Flyway V3 migration (staff_accounts, staff_account_permissions, revoked_tokens)
- StaffAccountRepository + RevokedTokenRepository
- TokenRevocationService with Caffeine cache (60s TTL, 10k max)
- StaffPermissionChecker SpEL bean (@staffPermissions.has)
- PreventionOfficerChecker SpEL bean (@preventionOfficer.check)
- JwtService: added jti claim + generateStaffAccessToken + extractJti/extractPermissions
- JwtAuthFilter: token blacklist check via TokenRevocationService
- SecurityConfig: STAFF role added to endpoint matchers
- Controllers updated with @PreAuthorize for fine-grained access
- TokenCleanupScheduler (daily 03:00 cleanup of expired revoked tokens)
- Caffeine dependency added to cannamanage-service
- Unit tests: StaffPermissionCheckerTest (7), TokenRevocationServiceTest (9)

+# Plan Review: CannaManage Sprint 3
+
+**Date:** 2026-06-11  
+**Reviewer:** Roo (Plan Reviewer)  
+**Documents:** Sprint 3 Plan v2 (APPROVED by Planner)  
+**Verdict:** ✅ APPROVED
+
+---
+
+## Summary
+
+The Sprint 3 plan is comprehensive, technically sound, and well-ordered. All deferred Sprint 2 features (staff, portal, reports, prevention officer, club settings) are covered. Architecture decisions are consistent with the existing codebase. The plan correctly builds on Sprint 2's shared-schema + TenantFilterAspect pattern rather than the architecture doc's theoretical schema-per-tenant model. 7 non-blocking findings identified — all are suggestions for improvement, none require plan revision.
+
+---
+
+## Review Checklist
+
+### 1. Does the plan cover ALL deferred Sprint 2 items?
+
+| Deferred Item | Plan Coverage | Status |
+|---------------|--------------|--------|
+| STAFF role | Phase 1 (StaffPermission enum, StaffAccount entity, SpEL checker) | ✅ |
+| Member portal | Phase 5 (session-based SecurityFilterChain, PortalController) | ✅ |
+| Reports | Phase 4 (ReportController, iText 7 PDF, Commons CSV) | ✅ |
+| Prevention Officer | Phase 6 (configurable limit, assignment endpoint, under-21 gate) | ✅ |
+| Club settings | Phase 2 (ClubController GET/PUT /clubs/me, stats) | ✅ |
+| Integration tests | Phase 7 (Testcontainers PostgreSQL, 6 test classes) | ✅ |
+
+**Result: ✅ PASS** — All deferred items fully addressed.
+
+---
+
+### 2. Architecture consistency with Sprint 2 patterns
+
+| Pattern | Sprint 2 Implementation | Sprint 3 Plan | Consistent? |
+|---------|------------------------|---------------|-------------|
+| Tenant isolation | `TenantFilterAspect` (shared-schema, Hibernate @Filter) | Continues shared-schema; `staff_accounts` has `tenant_id` | ✅ |
+| JWT auth | `JwtService` + `JwtAuthFilter` (stateless, JJWT) | Extends with `jti` + `permissions` claims | ✅ |
+| SecurityConfig | `@Order(1)` API + `@Order(2)` Public | Inserts Portal `@Order(2)`, shifts Public to `@Order(3)` | ✅ |
+| Role model | `UserRole` enum: `ROLE_ADMIN`, `ROLE_STAFF`, `ROLE_MEMBER` | Uses same enum; STAFF already present in code | ✅ |
+| Entity base | `AbstractTenantEntity` with `tenant_id` | New entities (StaffAccount, InviteToken) follow same pattern | ✅ |
+| Repositories | Spring Data JPA in `cannamanage-service/.../repository/` | New repos placed in same package | ✅ |
+
+**Result: ✅ PASS** — Fully consistent with established patterns.
+
+---
+
+### 3. Staff permission model well-defined?
+
+| Aspect | Assessment |
+|--------|-----------|
+| Enum values | 8 permissions covering all current features + 1 future (`MANAGE_GROW_CALENDAR`) | ✅ |
+| Storage | JSONB on `staff_accounts` — correct for PostgreSQL, supports flexible permission sets | ✅ |
+| Enforcement | SpEL `@PreAuthorize` + custom `StaffPermissionChecker` bean | ✅ |
+| JWT embedding | Permissions in JWT for stateless checks; blacklist fallback for revoked tokens | ✅ |
+| ADMIN bypass | `StaffPermissionChecker.has()` returns `true` for ADMIN role first | ✅ |
+| Templates | 3 role templates (Ausgabe, Lager, Vorstand) — matches architecture doc | ✅ |
+
+**Result: ✅ PASS** — Well-designed, DSGVO-compliant least-privilege model.
+
+---
+
+### 4. Member portal auth design clean?
+
+| Aspect | Assessment |
+|--------|-----------|
+| Dual SecurityFilterChain | `@Order(2)` for `/portal/**` — correct isolation from API chain | ✅ |
+| Session-based | `SessionCreationPolicy.IF_REQUIRED` + 30min timeout | ✅ |
+| CSRF | Enabled via `CookieCsrfTokenRepository.withHttpOnlyFalse()` — React SPA can read cookie | ✅ |
+| Read-only | All portal endpoints are GET — minimal attack surface | ✅ |
+| Data isolation | Member can only see own data (enforced by `memberId` from session principal) | ✅ |
+| `SameSite=Strict` | Correct for CSRF prevention | ✅ |
+
+**Result: ✅ PASS** — Clean separation of concerns.
+
+---
+
+### 5. Dependencies pinned to specific versions?
+
+| Library | Plan Version | Pinned? |
+|---------|-------------|---------|
+| iText 7 | `8.0.x` | ⚠️ Range |
+| Apache Commons CSV | `1.11+` | ⚠️ Range |
+| Caffeine | `3.1+` | ⚠️ Range |
+| Spring Boot Starter Mail | Boot-managed | ✅ (BOM) |
+| Testcontainers | `1.19+` | ⚠️ Range |
+
+**Result: ⚠️ WARNING (non-blocking)** — Versions use ranges instead of exact pins. This is acceptable for a plan document (exact versions determined at implementation time by checking latest stable), but the implementor should pin exact versions in the POM.
+
+---
+
+### 6. Flyway V3 migration complete?
+
+| Schema Change | Covered in V3? |
+|---------------|---------------|
+| `staff_accounts` table | ✅ Full DDL with JSONB, indexes, unique constraint |
+| `revoked_tokens` table | ✅ With jti index + expires index |
+| `invite_tokens` table | ✅ With token index, FK to users |
+| `users.prevention_officer` column | ✅ `ALTER TABLE ADD COLUMN` |
+| Club extension columns (9 columns) | ✅ All `ALTER TABLE ADD COLUMN IF NOT EXISTS` |
+
+**Result: ✅ PASS** — All new tables and columns defined in a single idempotent migration.
+
+---
+
+### 7. Test plan comprehensive?
+
+| Phase | Unit Tests | Integration Tests | Total |
+|-------|-----------|-------------------|-------|
+| P1 (Staff + Revocation) | T-01 to T-06 | — | 6 |
+| P2 (Club) | T-07 to T-10 | — | 4 |
+| P3 (Staff CRUD + Invite) | T-11 to T-14 | — | 4 |
+| P4 (Reports) | T-15 to T-18 | — | 4 |
+| P5 (Portal) | — | T-19, T-20 | 2 |
+| P6 (Prevention Officer) | T-21, T-22 | — | 2 |
+| P7 (Integration) | — | T-23 to T-26 | 4 |
+| **Total** | **18** | **8** | **26** |
+
+Coverage check:
+- Every phase has at least one test: ✅
+- Edge cases (expired token, invalid regex, permission denial): ✅
+- E2E flows (invite → set-password → login → permission check): ✅
+- Tenant isolation: ✅
+- Token revocation lifecycle: ✅
+
+**Result: ✅ PASS** — Comprehensive coverage matching all implementation phases.
+
+---
+
+### 8. Gaps between API spec and implementation plan?
+
+| API Spec Endpoint | Sprint 3 Plan | Gap? |
+|-------------------|---------------|------|
+| `GET /clubs/me` (§6.1) | Phase 2 — `ClubController` | ✅ Covered |
+| `PUT /clubs/me` (§6.2) | Phase 2 — `ClubController` | ✅ Covered |
+| `GET /clubs/me/stats` (§6.3) | Phase 2 — `ClubStatsResponse` DTO | ✅ Covered |
+| `POST /auth/logout` (§5.3) | Not explicitly addressed | ⚠️ See finding #3 |
+| `GET /reports/monthly` (§10) | Phase 4 — `ReportController` | ✅ Covered |
+| `GET /reports/members` (§10) | Phase 4 — member list export | ✅ Covered |
+| `GET /reports/recall/{batchId}` (§10) | Phase 4 — recall report | ✅ Covered |
+| Staff endpoints (not in spec) | Phase 3 — new endpoints | ℹ️ Plan extends spec |
+| Portal endpoints (not in spec) | Phase 5 — new `/portal/**` | ℹ️ Plan extends spec |
+| `POST /auth/set-password` (not in spec) | Phase 3 step 3.9 | ℹ️ Plan extends spec |
+
+**Result: ✅ PASS** — One minor gap (logout integration), otherwise plan both implements spec and correctly extends it for Sprint 3 scope.
+
+---
+
+### 9. Token revocation/blacklist approach sound?
+
+| Aspect | Assessment |
+|--------|-----------|
+| DB-backed (no Redis) | Correct for MVP scale — simple, durable, no infrastructure dependency | ✅ |
+| Caffeine cache (60s TTL, 10K max) | Appropriate tradeoff — worst case 60s window after revocation | ✅ |
+| `jti` claim in JWT | Required for per-token revocation — currently missing, plan adds it | ✅ |
+| `revokeAllForUser()` | Called on permission change + staff deactivation — correct triggers | ✅ |
+| Cleanup scheduler (daily 3 AM) | Removes expired tokens to prevent table bloat | ✅ |
+| Index on `jti` | Fast lookup for blacklist check | ✅ |
+| Index on `expires_at` | Fast cleanup queries | ✅ |
+
+**Result: ✅ PASS** — Sound, pragmatic approach for a club-scale application.
+
+---
+
+### 10. Risks not addressed?
+
+| Potential Risk | Addressed? | Notes |
+|----------------|-----------|-------|
+| iText AGPL license | ✅ | Risk table mentions it, mitigation: switch to OpenPDF before go-live |
+| Boot 4 `@EntityScan` issue | ✅ | Phase 7 step 7.1 explicitly addresses it |
+| JSONB + Hibernate 6 | ✅ | `@JdbcTypeCode(SqlTypes.JSON)` mentioned |
+| SMTP delivery | ✅ | Mailpit for dev, transactional email service for prod |
+| Cache staleness | ✅ | Accepted as non-critical for club app |
+| Portal CSRF + SPA | ✅ | `CookieCsrfTokenRepository.withHttpOnlyFalse()` |
+| `JwtAuthFilter` portal path exclusion | ⚠️ | See finding #5 |
+| Email domain regex DoS | ⚠️ | See finding #6 |
+
+**Result: ✅ PASS** — All major risks addressed. Two minor items noted below.
+
+---
+
+## Findings
+
+### ⚠️ Warnings (non-blocking — implement-time improvements)
+
+#### 1. Dependency versions not pinned
+
+**Plan §9** uses version ranges (`8.0.x`, `1.11+`, `3.1+`).
+
+**Recommendation:** At implementation time, pin exact versions in the POM:
+- iText 7: `8.0.5`
+- Commons CSV: `1.12.0`
+- Caffeine: `3.1.8`
+- Testcontainers: `1.20.1`
+
+---
+
+#### 2. `revoked_tokens` table has no `tenant_id` column
+
+The token blacklist is global across all tenants. This works correctly (tokens are unique by `jti` regardless of tenant), but it means:
+- `revokeAllForUser(userId)` queries ALL tenants' revoked tokens
+- No ability to purge one tenant's revoked tokens independently
+
+**Recommendation:** Consider adding `tenant_id` for operational convenience. Not blocking — the current design is functionally correct.
+
+---
+
+#### 3. `POST /auth/logout` not integrated with token revocation
+
+API spec §5.3 defines a logout endpoint that invalidates the refresh token. Sprint 3's `TokenRevocationService` adds access token revocation. The plan doesn't explicitly describe how these interact.
+
+**Recommendation:** On `POST /auth/logout`:
+1. Revoke refresh token (existing behavior)
+2. Also add current access token's `jti` to `revoked_tokens` (new behavior)
+
+This ensures immediate invalidation rather than waiting for natural token expiry. Implementor should handle this in Phase 1.
+
+---
+
+#### 4. Portal `formLogin` with JSON API may need `AuthenticationSuccessHandler`
+
+The plan describes portal as "JSON API" (Decision D2: no Thymeleaf) but configures `formLogin()` with `defaultSuccessUrl`. Standard `formLogin` returns HTTP redirects (302), not JSON responses.
+
+**Recommendation:** Implement a custom `AuthenticationSuccessHandler` that returns `200 OK` with session info as JSON, and a custom `AuthenticationFailureHandler` returning `401` JSON error. This aligns with the SPA architecture.
+
+---
+
+#### 5. `JwtAuthFilter.shouldNotFilter()` needs `/portal/**` exclusion
+
+Current `shouldNotFilter()` skips `/api/v1/auth/`, `/swagger-ui`, `/v3/api-docs`. The plan adds a portal with session-based auth, but the JWT filter will still process `/portal/**` requests (finding no Bearer header → passes through).
+
+**Recommendation:** Add `/portal/` to `shouldNotFilter()` for clarity and to avoid unnecessary filter processing:
+```java
+return path.startsWith("/api/v1/auth/")
+    || path.startsWith("/portal/")  // ← add this
+    || path.startsWith("/swagger-ui")
+    || path.startsWith("/v3/api-docs");
+```
+
+Not strictly blocking (filter already passes through when no Bearer header present), but cleaner.
+
+---
+
+#### 6. Regex pattern validation — potential ReDoS
+
+`validateEmailDomain()` uses `email.matches(club.getAllowedEmailPattern())` with admin-supplied regex. Malicious or poorly written regex could cause catastrophic backtracking (ReDoS).
+
+**Recommendation:** Add a timeout or use `Pattern.compile()` with a simple validation check:
+```java
+try {
+    Pattern.compile(pattern);  // validates syntax
+    // Additionally: reject patterns with known dangerous constructs
+    // Or use a timeout: java.util.concurrent.CompletableFuture with timeout
+} catch (PatternSyntaxException e) {
+    throw new InvalidRegexException(pattern);
+}
+```
+
+The plan does validate invalid regex (step 2.7, test T-10) but doesn't mention ReDoS protection specifically.
+
+---
+
+#### 7. Architecture doc deviation should be noted
+
+The architecture doc (03-Architecture.md) describes:
+- Schema-per-tenant (Sprint 2 implemented shared-schema with `tenant_id`)
+- `ROLE_CLUB_ADMIN` / `ROLE_PREVENTION_OFFICER` (code uses `ROLE_ADMIN` / boolean flag)
+- 8-hour access token (code uses 1-hour)
+
+These are expected evolutionary deviations — the architecture doc reflects initial design, and Sprint 2 made pragmatic choices. The architecture doc should be updated to reflect reality, but this doesn't block Sprint 3.
+
+**Recommendation:** Add a backlog item to sync the wiki architecture doc with actual implementation post-Sprint 3.
+

+## Verdict
+
+### ✅ APPROVED
+
+The Sprint 3 plan is complete, technically sound, and ready for implementation. All 10 review checklist items pass. 7 non-blocking warnings are noted as implementation-time improvements — none require plan revision.
+
+**Recommendation:** Proceed to implementation. The implementor should address warnings #3 (logout integration), #4 (portal auth handlers), and #5 (JwtAuthFilter exclusion) during Phase 1 and Phase 5 respectively.

+# CannaManage — Sprint 3 Implementation Plan
+
+**Date:** 2026-06-11  
+**Author:** Patrick Plate / Lumen (Planner)  
+**Status:** ✅ APPROVED v2 — GO received  
+**Base Branch:** `sprint/2-api`  
+**Sprint Branch:** `sprint/3-staff-portal`  
+**Sprint Goal:** Staff permission model + Token revocation + Member portal + Club/Report controllers + Prevention Officer + Invite flow
+
+---
+
+## 0. Decisions (Confirmed by Patrick)
+
+| # | Decision | Detail |
+|---|----------|--------|
+| D1 | JWT invalidation | **Token blacklist** — `revoked_tokens` DB table + Caffeine cache (60s TTL). On permission change, all user's tokens revoked. |
+| D2 | Portal rendering | **JSON API** — no Thymeleaf. React SPA consumes `/portal/**` with session cookies. |
+| D3 | Prevention officer | **Multiple, configurable** — `max_prevention_officers` on Club entity (default 2). Enforced on assignment. |
+| D4 | PDF branding | **Minimal branding** — club name header, generated-at timestamp footer, page numbers. Inspection-ready. |
+| D5 | Integration test DB | **Testcontainers PostgreSQL** — full fidelity for JSONB columns. |
+| D6 | Staff creation | **Invite flow** — admin creates account, email invite sent, staff sets own password. Requires Spring Mail. |
+| D7 | Email domain whitelist | **Regex pattern on Club settings** — `allowed_email_pattern` column, validated on invite. NULL = unrestricted. |
+
+---
+
+## 1. Sprint 2 Recap (Context)
+
+| Delivered | Status |
+|-----------|--------|
+| JWT auth (login + refresh with token rotation) | ✅ |
+| SecurityConfig with ADMIN + MEMBER roles | ✅ |
+| TenantFilterAspect (Hibernate @Filter activation) | ✅ |

+| DistributionController (compliance-gated) | ✅ |
+| StockController (batches) | ✅ |
+| ComplianceController (wraps service) | ✅ |
+| OpenAPI/Swagger | ✅ |
+| Flyway V2 migration | ✅ |
+| 25 unit tests passing | ✅ |
+
+**Deferred from Sprint 2:** STAFF role, Member portal, Club settings, Report generation, Prevention Officer, Integration tests.
+
+---
+
+## 2. Sprint 3 Scope
+
+### ✅ IN Scope
+
+| # | Feature | Priority | Effort |
+|---|---------|----------|--------|
+| 1 | **Staff permission model** — `StaffPermission` enum, `staff_accounts` table, `StaffPermissionChecker` SpEL bean | P0 | 1.5 days |

+- Schema-per-tenant migration
+- Grow calendar / cultivation tracking
+- DSGVO consent management UI
+- PDF template customization per club (logo upload)
+- Password reset flow (separate from invite)
+
+---
+
+## 3. Architecture Decisions
+
+### 3.1 Staff Permission Model
+
+```java
+// New enum — cannamanage-domain
+public enum StaffPermission {
+    RECORD_DISTRIBUTION,      // can record distributions
+    VIEW_MEMBER_LIST,         // can view member roster
+    VIEW_MEMBER_QUOTA,        // can view individual member quota
+    ADD_MEMBER,               // can register new members
+    VIEW_STOCK,               // can view batch/strain inventory
+    RECORD_STOCK_IN,          // can add new batches
+    VIEW_COMPLIANCE_REPORT,   // can generate/download reports
+    MANAGE_GROW_CALENDAR      // future — cultivation calendar
+}
+```
+
+**Database design:**
+
+```sql
+CREATE TABLE staff_accounts (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    tenant_id UUID NOT NULL,
+    user_id UUID NOT NULL REFERENCES users(id),
+    display_name VARCHAR(255) NOT NULL,
+    granted_permissions JSONB NOT NULL DEFAULT '[]'::jsonb,
+    template_name VARCHAR(100),  -- 'ausgabe', 'lager', 'vorstand', or NULL
+    active BOOLEAN NOT NULL DEFAULT true,
+    created_at TIMESTAMP NOT NULL DEFAULT NOW(),
+    updated_at TIMESTAMP NOT NULL DEFAULT NOW(),
+    CONSTRAINT uq_staff_tenant_user UNIQUE(tenant_id, user_id)
+);
+```
+
+**Authorization — custom SpEL bean:**
+
+```java
+@Component("staffPermissions")
+public class StaffPermissionChecker {
+    
+    public boolean has(MethodSecurityExpressionOperations root, StaffPermission required) {
+        Authentication auth = root.getAuthentication();
+        if (auth.getAuthorities().stream().anyMatch(a -> a.getAuthority().equals("ROLE_ADMIN"))) 
+            return true;
+        if (auth.getAuthorities().stream().noneMatch(a -> a.getAuthority().equals("ROLE_STAFF"))) 
+            return false;
+        
+        StaffAccount staff = staffAccountRepository.findByUserId(getUserId(auth));
+        return staff != null && staff.getGrantedPermissions().contains(required);
+    }
+}
+```
+
+**Usage:**
+
+```java
+@PreAuthorize("hasRole('ADMIN') or @staffPermissions.has(#root, T(de.cannamanage.domain.enums.StaffPermission).RECORD_DISTRIBUTION)")
+public ResponseEntity<DistributionResponse> recordDistribution(...)
+```
+
+**Staff permissions embedded in JWT:**
+
+```json
+{
+  "sub": "user-uuid",
+  "tenant_id": "tenant-uuid",
+  "role": "STAFF",
+  "permissions": ["RECORD_DISTRIBUTION", "VIEW_MEMBER_LIST", "VIEW_MEMBER_QUOTA"],
+  "jti": "unique-token-id",
+  "iat": 1712345678,
+  "exp": 1712349278
+}
+```
+
+The `jti` claim enables token revocation. Permissions in the JWT allow stateless checks (with blacklist validation as fallback for revoked tokens).
+
+---
+
+### 3.2 Token Revocation (Decision D1)
+
+**No Redis** — lightweight DB-based approach with in-memory caching:
+
+```sql
+CREATE TABLE revoked_tokens (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    jti VARCHAR(255) NOT NULL UNIQUE,
+    user_id UUID NOT NULL,
+    expires_at TIMESTAMP NOT NULL,
+    revoked_at TIMESTAMP NOT NULL DEFAULT NOW(),
+    reason VARCHAR(100)  -- 'permission_change', 'logout', 'admin_action'
+);
+
+CREATE INDEX idx_revoked_tokens_jti ON revoked_tokens(jti);
+CREATE INDEX idx_revoked_tokens_expires ON revoked_tokens(expires_at);
+```
+
+**Components:**
+
+```java
+@Service
+public class TokenRevocationService {
+    
+    private final Cache<String, Boolean> blacklistCache = Caffeine.newBuilder()
+        .expireAfterWrite(60, TimeUnit.SECONDS)
+        .maximumSize(10_000)
+        .build();
+    
+    public boolean isRevoked(String jti) {
+        return blacklistCache.get(jti, key -> 
+            revokedTokenRepository.existsByJti(key));
+    }
+    
+    public void revokeAllForUser(UUID userId) {
+        // Revoke all active tokens for this user
+        // Called when permissions change or admin deactivates staff
+    }
+}
+```
+
+**JwtAuthFilter integration:**
+
+```java
+// In JwtAuthFilter.doFilterInternal():
+String jti = jwtService.extractClaim(token, "jti");
+if (tokenRevocationService.isRevoked(jti)) {
+    response.sendError(401, "Token revoked");
+    return;
+}
+```
+
+**Cleanup scheduled task:**
+
+```java
+@Scheduled(cron = "0 0 3 * * *")  // daily at 3 AM
+public void cleanupExpiredTokens() {
+    revokedTokenRepository.deleteByExpiresAtBefore(Instant.now());
+}
+```
+
+---
+
+### 3.3 Member Portal Auth (Decision D2)
+
+Dual `SecurityFilterChain` — session-based for portal, JWT for API:
+
+```java
+@Bean
+@Order(2)
+public SecurityFilterChain portalSecurityFilterChain(HttpSecurity http) throws Exception {
+    http
+        .securityMatcher("/portal/**")
+        .csrf(Customizer.withDefaults())  // CSRF enabled
+        .sessionManagement(session -> session
+            .sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
+            .maximumSessions(1))
+        .formLogin(form -> form
+            .loginPage("/portal/login")
+            .loginProcessingUrl("/portal/login")
+            .defaultSuccessUrl("/portal/dashboard", true)
+            .failureUrl("/portal/login?error"))
+        .logout(logout -> logout
+            .logoutUrl("/portal/logout")
+            .logoutSuccessUrl("/portal/login?logout"))
+        .authorizeHttpRequests(auth -> auth
+            .requestMatchers("/portal/login", "/portal/css/**", "/portal/js/**").permitAll()
+            .requestMatchers("/portal/**").hasRole("MEMBER"));
+    
+    return http.build();
+}
+```
+
+**Portal JSON endpoints:**
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/portal/login` | POST | Form login (session cookie returned) |
+| `/portal/dashboard` | GET | Member dashboard (quota + recent distributions) |
+| `/portal/me` | GET | Own profile data |
+| `/portal/quota` | GET | Current month quota status |
+| `/portal/distributions` | GET | Own distribution history (paginated) |
+
+**Security invariants:**
+- Members ONLY access their own data (enforced by `memberId` from session principal)
+- All portal endpoints are GET (read-only) — no write operations
+- Session timeout: 30 minutes
+- `SameSite=Strict` cookie
+- CSRF token provided via `CookieCsrfTokenRepository.withHttpOnlyFalse()`
+

+
+### 3.4 Prevention Officer (Decision D3)
+
+**Configurable limit on Club entity:**
+
+```java
+// Club.java
+@Column(name = "max_prevention_officers")
+private Integer maxPreventionOfficers = 2;  // default: 2
+```
+
+**Enforcement on assignment:**
+
+```java
+public void assignPreventionOfficer(UUID userId) {
+    long currentCount = userRepository.countByTenantIdAndPreventionOfficerTrue(tenantId);
+    int limit = club.getMaxPreventionOfficers();
+    if (currentCount >= limit) {
+        throw new PreventionOfficerLimitExceededException(limit);
+    }
+    user.setPreventionOfficer(true);
+    userRepository.save(user);
+}
+```
+
+**Access control for under-21 data:**
+
+```java
+@PreAuthorize("hasRole('ADMIN') or @preventionOfficer.check(authentication)")
+public List<MemberResponse> getUnder21Members() { ... }
+```
+
+---
+
+### 3.5 Staff Invite Flow (Decision D6)
+
+**Sequence:**
+
+```
+1. Admin: POST /api/v1/staff { email, displayName, permissions, templateName? }
+2. System: validates email against club's allowed_email_pattern (D7)
+3. System: creates User (role=STAFF, active=false, no password)
+4. System: creates StaffAccount (permissions JSONB)
+5. System: creates InviteToken (72h expiry)
+6. System: sends email with link: https://{domain}/auth/set-password?token={token}
+7. Staff member: POST /api/v1/auth/set-password { token, password }
+8. System: validates token, sets password_hash, sets active=true
+9. Staff can now login via POST /api/v1/auth/login
+```
+
+**Database:**
+
+```sql
+CREATE TABLE invite_tokens (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    user_id UUID NOT NULL REFERENCES users(id),
+    token VARCHAR(255) NOT NULL UNIQUE,
+    expires_at TIMESTAMP NOT NULL,
+    used_at TIMESTAMP,
+    created_at TIMESTAMP NOT NULL DEFAULT NOW()
+);
+
+CREATE INDEX idx_invite_tokens_token ON invite_tokens(token);
+```
+
+**Spring Mail config (dev vs prod):**
+
+```yaml
+# application.yml
+spring:
+  mail:
+    host: ${SMTP_HOST:localhost}
+    port: ${SMTP_PORT:1025}  # Mailpit for dev
+    username: ${SMTP_USER:}
+    password: ${SMTP_PASSWORD:}
+    properties:
+      mail.smtp.auth: ${SMTP_AUTH:false}
+      mail.smtp.starttls.enable: ${SMTP_TLS:false}
+```
+
+---
+
+### 3.6 Email Domain Whitelist (Decision D7)
+
+**Club setting:**
+
+```java
+// Club.java
+@Column(name = "allowed_email_pattern")
+private String allowedEmailPattern;  // regex, NULL = unrestricted
+```
+
+**Validation in StaffService:**
+
+```java
+private void validateEmailDomain(String email, Club club) {
+    if (club.getAllowedEmailPattern() == null) return;  // unrestricted
+    if (!email.matches(club.getAllowedEmailPattern())) {
+        throw new EmailDomainNotAllowedException(email, club.getAllowedEmailPattern());
+    }
+}
+```
+
+**Example patterns:**
+- `^.*@gruener-daumen-ev\.de$` — club email only
+- `^.*@(verein\.de|gmail\.com|gmx\.de)$` — approved domains
+- `NULL` — any email accepted (default)
+
+---
+
+### 3.7 Report Generation (Decision D4)
+
+**OpenPDF (LGPL fork of iText 5) with minimal branding:**
+
+```java
+@Service
+public class PdfReportGenerator {
+
+    public byte[] renderMonthlyReport(MonthlyReport data, Club club) {
+        Document document = new Document(PageSize.A4);
+        // Header: club name + report title
+        document.add(new Paragraph(club.getName())
+            .setFont(PdfFontFactory.createFont(StandardFonts.HELVETICA_BOLD))
+            .setFontSize(16));
+        document.add(new Paragraph("Monatsbericht — " + data.getMonth())
+            .setFontSize(12));
+        
+        // Content: data tables...
+        
+        // Footer: generated timestamp + page numbers (via event handler)
+        document.close();
+        return baos.toByteArray();
+    }
+}
+```
+
+**PDF footer pattern (OpenPDF PdfPageEventHelper):**
+
+```java
+public class FooterHandler implements IEventHandler {
+    @Override
+    public void handleEvent(Event event) {
+        PdfDocumentEvent docEvent = (PdfDocumentEvent) event;
+        // Add: "Erstellt am: {timestamp}" + "Seite {n} von {total}"
+    }
+}
+```

+
+## 6. Flyway Migration V3
+
+Single migration covering all Sprint 3 schema changes:

+## 7. Updated SecurityConfig Structure (Target State)
+
+```java
+@Configuration

+## 9. Dependencies & Libraries
+
+| Library | Version | Purpose | New? |
+|---------|---------|---------|------|
+| OpenPDF (librepdf) | 2.0.4 | PDF report generation (LGPL — SaaS-safe) | ✅ New |
+| Apache Commons CSV | 1.11+ | CSV export | ✅ New |
+| Caffeine | 3.1+ | In-memory token blacklist cache | ✅ New |
+| Spring Boot Starter Mail | (Boot managed) | Email invite sending | ✅ New |
+| Testcontainers PostgreSQL | 1.19+ | Integration tests | Already in POM |
+| Spring Security Test | (Boot managed) | SecurityMockMvc | Already in POM |
+
+---
+
+## 10. Risk Assessment
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| ~~iText 7 license~~ — RESOLVED: using OpenPDF (LGPL) | — | — | No longer a risk. OpenPDF is LGPL 2.1, fully SaaS-compatible. |
+| Boot 4 `@EntityScan` blocks integration tests | Medium | Medium | Investigate `@AutoConfiguration` changes. Fallback: explicit `EntityManagerFactory` bean. |
+| JSONB + Hibernate 6 serialization issues | Low | Medium | Hibernate 6 supports JSONB via `@JdbcTypeCode(SqlTypes.JSON)`. Test early in Phase 1. |
+| SMTP delivery issues in prod | Low | Medium | Use transactional email service (Mailgun/Brevo free tier). Dev uses Mailpit (local). |
+| Caffeine cache staleness (60s window) | Low | Low | Acceptable: worst case a revoked token works for 60 more seconds. Not a real security hole for a club app. |
+| Portal CSRF + SPA interaction | Low | Low | `CookieCsrfTokenRepository.withHttpOnlyFalse()` → React reads `XSRF-TOKEN` cookie, sends as header. |
+

+
+## Findings
+
+### ⚠️ Medium Severity (should address during implementation)
+
+#### Finding #1: Invite token lacks complexity requirements for password
+
+**Phase:** 3 (Step 3.9: `POST /auth/set-password`)  
+**Risk:** Password strength not mentioned in plan  
+**Description:** The `SetPasswordRequest` DTO accepts a password, but the plan doesn't specify minimum complexity requirements. Weak passwords would undermine the security of staff accounts that have elevated permissions.
+
+**Recommendation:**
+```java
+// In SetPasswordRequest DTO validation
+@NotBlank
+@Size(min = 12, message = "Password must be at least 12 characters")
+@Pattern(regexp = "^(?=.*[a-z])(?=.*[A-Z])(?=.*\\d).*$",
+         message = "Password must contain uppercase, lowercase, and digit")
+private String password;
+```
+
+**Severity:** Medium — Staff accounts have elevated permissions (RECORD_DISTRIBUTION, VIEW_MEMBER_LIST with PII access).
+
+---
+
+#### Finding #2: Email domain whitelist regex — ReDoS vulnerability
+
+**Phase:** 2 (Step 2.7) + Phase 3 (Step 3.5)  
+**Risk:** Denial of Service via catastrophic backtracking  
+**Description:** The plan uses `email.matches(club.getAllowedEmailPattern())` where the pattern is admin-supplied. A malicious or poorly-constructed regex like `^(a+)+@evil.com$` can cause exponential backtracking.
+
+**Recommendation:**
+```java
+private void validateEmailDomain(String email, Club club) {
+    if (club.getAllowedEmailPattern() == null) return;
+    
+    // 1. Validate pattern syntax
+    Pattern pattern;
+    try {
+        pattern = Pattern.compile(club.getAllowedEmailPattern());
+    } catch (PatternSyntaxException e) {
+        throw new InvalidEmailPatternException("Invalid regex pattern on club settings");
+    }
+    
+    // 2. Apply with timeout protection
+    Matcher matcher = pattern.matcher(email);
+    ExecutorService executor = Executors.newSingleThreadExecutor();
+    Future<Boolean> future = executor.submit(matcher::matches);
+    try {
+        boolean matches = future.get(100, TimeUnit.MILLISECONDS);
+        if (!matches) throw new EmailDomainNotAllowedException(email);
+    } catch (TimeoutException e) {
+        future.cancel(true);
+        throw new InvalidEmailPatternException("Email pattern validation timed out — pattern may be too complex");
+    } finally {
+        executor.shutdownNow();
+    }
+}
+```
+
+Alternatively, restrict allowed patterns to a simple domain list (no arbitrary regex):
+```java
+// Simpler, safer approach
+@Column(name = "allowed_email_domains")
+private String allowedEmailDomains;  // comma-separated: "example.de,club.de"
+```
+
+**Severity:** Medium — An admin can DoS their own tenant's invite flow. Cross-tenant impact is blocked by TenantFilterAspect.
+
+---
+
+#### Finding #3: Invite token error responses may leak information
+
+**Phase:** 3 (Step 3.9: `POST /auth/set-password`)  
+**Risk:** Information disclosure / account enumeration  
+**Description:** Different error messages for "token not found", "token expired", and "token already used" allow an attacker to enumerate valid invite tokens and determine their state.
+
+**Recommendation:** Return a generic error message for all failure cases:
+```java
+// ❌ AVOID — reveals token state
+if (token == null) throw new NotFoundException("Token not found");
+if (token.getExpiresAt().isBefore(Instant.now())) throw new BadRequestException("Token expired");
+if (token.getUsedAt() != null) throw new BadRequestException("Token already used");
+
+// ✅ PREFERRED — generic response
+if (token == null || token.getExpiresAt().isBefore(Instant.now()) || token.getUsedAt() != null) {
+    throw new BadRequestException("Invalid or expired invitation link. Please contact your club administrator.");
+}
+```
+
+**Severity:** Medium — The `/auth/set-password` endpoint is public (no auth required). Token enumeration could allow unauthorized password setting if tokens are guessable (see Finding #7).
+
+---
+
+#### Finding #4: Invite token values must not appear in logs
+
+**Phase:** 3 (Steps 3.4, 3.5, 3.9)  
+**Risk:** Token leakage via log files  
+**Description:** The invite token is a bearer credential — anyone with the token value can set a password and gain staff access. If logged (e.g., in request logging, error logs, or debug statements), it becomes accessible to anyone with log access.
+
+**Recommendation:**
+```java
+// In EmailService — do NOT log the full token
+log.info("Invite email sent to {} for user {}", email, userId);
+// NOT: log.info("Invite sent with token {}", token);
+
+// In AuthController.setPassword — do NOT log the token value
+log.info("Password set successfully for invite (user: {})", userId);
+// NOT: log.debug("Processing set-password for token: {}", request.getToken());
+```
+
+Also ensure that Spring Boot request logging (if enabled) does not capture the token from the request body.
+
+**Severity:** Medium — Log access is typically broader than intended credential access.
+
+---
+
+### ℹ️ Low Severity (advisory — defense-in-depth suggestions)
+
+#### Finding #5: JWT permissions vs. DB permissions — stale permission window
+
+**Phase:** 1 (Steps 1.9, 1.10, 1.12)  
+**Risk:** Privilege escalation during 60s Caffeine cache TTL  
+**Description:** Staff permissions are embedded in the JWT. When an admin changes a staff member's permissions, `revokeAllForUser()` is called, which adds the old token's `jti` to the blacklist. However:
+
+1. The Caffeine cache has a 60s TTL — during this window, the old token could still be accepted by another node (if scaled horizontally in the future)
+2. More critically: if the revoked token check is cached as "not revoked" by Caffeine BEFORE the revocation occurs, it remains cached for up to 60s
+
+The plan correctly identifies this as an acceptable risk for a club-scale app.
+
+**Recommendation:** Document this 60-second window as a known limitation. For future scaling, consider:
+- Reducing Caffeine TTL to 10-15s (acceptable DB load for club scale)
+- Using a `LoadingCache` that checks a "last revocation timestamp" before returning cached false results
+
+**Severity:** Low — Acceptable for MVP. A staff member could perform unauthorized actions for at most 60 seconds after permission revocation.
+
+---
+
+#### Finding #6: Token revocation doesn't address refresh tokens
+
+**Phase:** 1 (Step 1.6: `TokenRevocationService`)  
+**Risk:** Revoked staff can still obtain new access tokens via refresh  
+**Description:** The plan's `revokeAllForUser()` revokes access token `jti` values in the blacklist. But the refresh token (used at `POST /auth/refresh`) has a separate 30-day lifetime. If only access tokens are revoked, the staff member can use their refresh token to obtain a new (valid) access token with the OLD permissions still embedded.
+
+**Recommendation:** On permission change or staff deactivation:
+1. Revoke all access tokens (current plan) ✅
+2. Also invalidate the user's refresh token (clear `refresh_token_hash` in `users` table) ✅ (must be explicitly added)
+
+```java
+public void revokeAllForUser(UUID userId) {
+    // 1. Blacklist all active access tokens
+    List<RevokedToken> tokens = ... ;
+    revokedTokenRepository.saveAll(tokens);
+    blacklistCache.invalidateAll(); // force re-check
+    
+    // 2. Also invalidate refresh token
+    userRepository.clearRefreshTokenHash(userId);
+}
+```
+
+**Severity:** Low — The plan's Step 3.11 updates `AuthService.login()` to reject `active=false` users, which partially mitigates this. But a user who is still `active=true` with changed permissions could refresh and get a new token with stale permissions if the refresh endpoint doesn't re-check permissions from DB.
+
+---
+
+#### Finding #7: Invite token must use cryptographically secure random generation
+
+**Phase:** 3 (Step 3.2: `InviteToken` entity)  
+**Risk:** Predictable tokens enable unauthorized account takeover  
+**Description:** The plan specifies `token VARCHAR(255) NOT NULL UNIQUE` but doesn't specify the generation method. If `UUID.randomUUID()` is used, it's type-4 (PRNG-based) which is generally secure but predictable under certain JVM conditions.
+
+**Recommendation:** Use `SecureRandom` with sufficient entropy:
+```java
+// In InviteTokenService or StaffService
+private String generateSecureToken() {
+    byte[] bytes = new byte[32]; // 256 bits of entropy
+    new SecureRandom().nextBytes(bytes);
+    return Base64.getUrlEncoder().withoutPadding().encodeToString(bytes);
+}
+```
+
+This produces a 43-character URL-safe token with 256 bits of entropy — sufficient to prevent brute-force guessing even on the public `/auth/set-password` endpoint.
+
+**Severity:** Low — The 72-hour expiry mitigates brute-force attacks. But with `UUID.randomUUID()` (122 bits of randomness), an attacker would need ~5.3 × 10³⁶ attempts — already computationally infeasible. This finding is defense-in-depth.
+
+---
+
+#### Finding #8: Rate limiting on `POST /auth/set-password`
+
+**Phase:** 3 (Step 3.9)  
+**Risk:** Brute-force invite token guessing  
+**Description:** The `POST /auth/set-password` endpoint is public (no authentication required) and accepts a token in the request body. Without rate limiting, an attacker could attempt to brute-force valid tokens.
+
+**Recommendation:** Apply rate limiting per IP:
+```java
+// In SecurityConfig or via @RateLimiter annotation
+.requestMatchers("/api/v1/auth/set-password").permitAll()
+// Add: rate limit 5 requests per minute per IP
+```
+
+Options:
+- Spring Boot Starter Rate Limiter (Bucket4j)
+- Custom `Filter` with Caffeine-based per-IP counter
+- Nginx-level rate limiting (`limit_req_zone`)
+
+**Severity:** Low — Token entropy (Finding #7) makes brute-force infeasible even without rate limiting. This is defense-in-depth.

+
+## Identified False Positives
+
+| Pattern | Why It's Safe |
+|---------|--------------|
+| SMTP credentials in `application.yml` | All via `${SMTP_*}` env var placeholders — not hardcoded |
+| JWT secret in `JwtService` | Via `@Value("${cannamanage.security.jwt.secret}")` — externalized |
+| `allowedEmailPattern` stored in DB | Admin-only configurable; only affects their own tenant |
+| `staff_accounts.granted_permissions` as JSONB | Not a credential; contains only permission names |
+
+---
+
+## Architecture-Level Security Assessment
+
+### Token Revocation Design (D1)
+
+| Aspect | Security Rating | Notes |
+|--------|----------------|-------|
+| DB persistence | ✅ Strong | Survives restarts; durable record |
+| Caffeine cache | ⚠️ Acceptable | 60s stale window documented and accepted |
+| `jti` uniqueness | ✅ Strong | UUID-based, UNIQUE constraint in DB |
+| Cleanup scheduler | ✅ Good | Prevents table bloat; respects token expiry |
+| Horizontal scale readiness | ⚠️ Weak | Cache is per-instance; need shared cache for multi-node |
+
+### Staff Permission Model
+
+| Aspect | Security Rating | Notes |
+|--------|----------------|-------|
+| ADMIN bypass | ✅ Correct | `StaffPermissionChecker` returns true for ADMIN first |
+| STAFF denial by default | ✅ Correct | If no permissions found → deny |
+| JSONB storage | ✅ Good | Flexible, supports audit trail of changes |
+| JWT-embedded permissions | ⚠️ Acceptable | Stale for max token lifetime after revocation |
+| Tenant isolation | ✅ Strong | `tenant_id` on `staff_accounts`; TenantFilterAspect enforced |
+
+### Invite Flow Security
+
+| Aspect | Security Rating | Notes |
+|--------|----------------|-------|
+| Token expiry (72h) | ✅ Good | Reasonable window; not too long |
+| Single-use enforcement | ✅ Strong | `used_at` timestamp prevents reuse |
+| Public endpoint exposure | ⚠️ Acceptable | Only accepts token + password; generic errors recommended |
+| Email delivery trust | ⚠️ Inherent risk | Email is not a secure channel; standard for invite flows |
+| Active=false until password set | ✅ Strong | Prevents login before activation |
+
+---
+
+## Verdict
+
+### ✅ PASS
+
+No Critical or High severity findings. The design is fundamentally sound for a club-scale application.
+
+**8 findings total:**
+- 0 Critical
+- 0 High
+- 4 Medium (should address during implementation)
+- 4 Low (defense-in-depth suggestions)
+
+**Key implementation instructions for the developer:**
+1. Add password complexity validation on `SetPasswordRequest` (Finding #1)
+2. Add regex timeout or switch to domain list for email whitelist (Finding #2)
+3. Use generic error messages on `/auth/set-password` (Finding #3)
+4. Never log invite token values (Finding #4)
+5. Clear refresh token hash on permission change (Finding #6)
+6. Use `SecureRandom` for invite token generation (Finding #7)
