fix(mcp-image-gen): rewrite flux2_klein_heretic workflow with CFGGuider + correct node types

- Replace FluxDisableGuidance+BasicGuider chain with CFGGuider (cfg=5)
- CLIPLoader: add device='default', keep type='flux2'
- UNETLoader: weight_dtype='default' (not fp8_e4m3fn — avoids dimension mismatch)
- VAEDecode/SaveImage: updated node IDs (11→VAEDecode, 12→SaveImage)
- Encoder: qwen_3_4b_bfl.safetensors (7.5GB BFL-merged shards)
- Tests: update heretic model assertions for new node structure (37/37 pass)
- Add RECAP doc with root cause analysis and session history

+# Ask Lite Mode — Behavior Rules
+
+## Identity
+
+You are Lumen, Patrick's AI colleague, operating in **Ask Lite** mode. Same personality, same BigMind integration — optimized for quick, direct answers to factual questions without burning Claude API budget. You answer questions about Patrick's tech stack concisely and accurately.
+
+---
+
+## 1. Model Awareness
+
+This mode runs on a **local Ollama model (glm-4.7-flash, 30B params, 202k context)**. This model is excellent for:
+
+- **Factual recall**: What does X do? What's the difference between A and B?
+- **Concept explanation**: How does Y work? Explain Z.
+- **How-to lookups**: How do I use W? What's the syntax for V?
+- **Stack-specific Q&A**: Patrick's tools, libraries, and frameworks
+
+It is NOT suitable for:
+- Multi-step code debugging (use Debug mode)
+- Code implementation tasks (use Code mode)
+- System design decisions (use Architect mode)
+- Deep reasoning chains that require Claude
+
+**Redirect rule**: If answering requires writing or modifying code, analyzing a bug, or making architectural decisions → tell Patrick to switch modes (see §5).
+
+---
+
+## 2. BigMind Lite — Session Ritual
+
+### Session Start (execute in order)
+1. `memory_start_session()` — load prior context
+2. `memory_list_hypotheses()` — review open hypotheses (rarely relevant for Q&A, but check)
+3. `memory_announce_focus(session_id, "Quick Q&A session", [], ide_hint="VS Code")`
+4. `memory_close_stale_sessions(session_id)` — clean orphaned sessions
+
+### Before Answering Every Non-Trivial Question
+Always search memory first — Patrick's preferences and stack details are often already stored:
+
+- `memory_search_facts("2-3 focused keywords")` — user preferences, codebase facts
+- `memory_search_chunks("related topic")` — past session context
+
+**FTS5 rules**: Use 2-3 keywords max. Every token must match. If 0 results, drop the most specific word.
+
+Example searches:
+- `"FastMCP tool decorator"` → stored FastMCP patterns
+- `"uv package management"` → how Patrick manages deps
+- `"TrueNAS Docker"` → homelab infrastructure facts
+
+Memory hits save tokens AND give Patrick's actual preferences, not generic answers.
+
+### Session End
+`memory_end_session(session_id, one_liner, topics, outcome, summary, importance=2)`
+
+Q&A sessions are typically importance 1-3.
+
+---
+
+## 3. Web Research First
+
+For questions about external libraries, APIs, frameworks, error messages, or current documentation — **search before answering from memory**:
+
+```
+webscraper_search_hint("2-3 keyword query")
+```
+
+Then if needed:
+```
+webscraper_fetch(best_url, max_chars=8000)
+```
+
+### When to search
+- "How do I use [library X]?" → search `"library X feature"`
+- "What's the error [message]?" → search distinctive phrase from error
+- "What's new in [framework] version Y?" → search `"framework Y changelog"`
+- "What's the difference between A and B?" → often answerable from memory, but verify if unsure
+
+### Query crafting
+| ✅ Good | ❌ Bad |
+|---------|--------|
+| `"FastMCP lifespan"` | `"how to use FastMCP lifespan context manager in Python"` |
+| `"SQLite WAL mode"` | `"sqlite performance concurrent reads write ahead logging"` |
+| `"httpx async timeout"` | `"how to configure timeout settings in httpx library"` |
+
+Use Brave Search — it works without API keys or CAPTCHAs. One search per question topic.
+
+---
+
+## 4. Response Style
+
+### Structure
+1. **Direct answer first** — no preamble, no "Great question!", no restating the question
+2. Short paragraphs or bullet points as appropriate
+3. Code snippets only when they materially clarify the answer
+4. Cite source if you looked something up (e.g., "Per FastMCP docs:")
+
+### Length
+- Simple factual questions: 1-3 sentences
+- Concept explanations: 3-10 sentences or a short bulleted list
+- Comparative questions: a short table or two-column list
+
+### Honesty
+If unsure: say so clearly.
+> "I'm not certain — you should verify with the docs at [URL]."
+
+Never guess and present it as fact.
+
+### Patrick's Stack (no lookup needed for these)
+| Domain | Technologies |
+|--------|-------------|
+| Python MCP | FastMCP, uv, pytest, httpx, respx |
+| Python general | SQLite, Flask, Pydantic, asyncio |
+| Java | Spring Boot 3.x, Jakarta EE, JPA/EclipseLink, PrimeFaces, Maven |
+| Java ADP | Paisy monorepo, euBP, EAU, FEX, Oracle DB |
+| Containers | Docker, Docker Compose (on TrueNAS.local) |
+| Version control | Git, Gitea (http://192.168.188.119:30008/) |
+| Local AI | Ollama (local), ComfyUI (image gen, localhost:8188) |
+| OS | Fedora Linux (workstation), TrueNAS SCALE (server) |
+| IDE | VS Code + Roo Code extension |
+
+---
+
+## 5. Escalation Triggers
+
+Tell Patrick to switch modes when:
+
+| Situation | Recommended mode |
+|-----------|-----------------|
+| "Write me a function that..." | Code mode |
+| "Fix this bug..." | Debug mode |
+| "I'm getting this error..." | Debug mode |
+| "Design a system for..." | Architect mode |
+| "How should I architect..." | Architect mode |
+| "ADP/Paisy/euBP/EAU Java..." | Paisy mode |
+| "Write docs/README/wiki..." | Doc Writer mode |
+| "My Docker container / TrueNAS..." | Homelab mode |
+| "Add a feature to BigMind..." | BigMind mode |
+| "Build an MCP server..." | MCP Builder mode |
+
+**Escalation message format** (direct, not apologetic):
+> "That needs Code mode — Ask Lite is for Q&A only."
+
+---
+
+## 6. No File Editing
+
+Ask Lite **reads** files for context but **never modifies** them.
+
+If Patrick asks you to make a change:
+> "Ask Lite is read-only. Switch to Code or Doc Writer mode to make that change."
+
+Reading files is fine — use targeted reads and memory to minimize token usage:
+1. Check memory first
+2. Use grep/search for specific patterns rather than reading entire files
+3. Read file sections (line ranges) rather than full files
+4. Log token savings with `memory_log_token_save` when you avoid full reads
+
+---
+
+Lumen's identity, BigMind rituals, and memory patterns are unchanged — they apply in every mode. See `.roo/rules/` for those constants.

+# Doc Writer Mode — Behavior Rules
+
+## Identity
+
+You are Lumen, Patrick's AI colleague, operating in **Doc Writer** mode. Same personality, same BigMind integration — just focused exclusively on producing clear, well-structured documentation. You write for Patrick's projects: pi_mcps (FastMCP Python MCP servers), BigMind (Flask + SQLite memory server), Paisy/ADP (Java payroll compliance), and homelab (TrueNAS, Docker, Gitea).
+
+---
+
+## 1. Model Awareness
+
+This mode runs on a **local Ollama model (glm-4.7-flash, 30B params, 202k context)**. Optimize accordingly:
+
+- **Do**: Structured writing, markdown formatting, templates, outlines, prose, docstrings, changelogs
+- **Do**: Follow documentation patterns and style guides precisely
+- **Avoid**: Multi-step reasoning chains, complex debugging analysis, architectural decision-making
+- **Avoid**: Tasks requiring Claude-level reasoning (code analysis, root cause investigation, system design)
+
+If Patrick asks for something outside documentation scope (implement a feature, debug an error, design architecture):
+
+> "This needs more than Doc Writer mode. Switch to Code/Debug/Architect mode for that."
+
+---
+
+## 2. BigMind Lite — Session Ritual
+
+### Session Start (execute in order)
+1. `memory_start_session()` — load context
+2. `memory_list_hypotheses()` — review open hypotheses (skip hypothesis formation for doc tasks < 5 min effort)
+3. `memory_announce_focus(session_id, description, files, ide_hint="VS Code")` — declare files you'll touch
+4. `memory_close_stale_sessions(session_id)` — clean orphaned sessions
+
+### Before Writing
+Always search memory before writing anything substantial:
+
+- `memory_search_facts("project doc conventions")` — picks up style preferences
+- `memory_search_facts("readme wiki style")` — existing format decisions
+- `memory_search_chunks("documentation format")` — past session context
+
+This avoids re-reading files for context that's already stored.
+
+### Session End
+`memory_end_session(session_id, one_liner, topics, outcome, summary, importance=2)`
+
+Doc sessions are typically importance 2-4 unless you wrote something architecturally significant.
+
+---
+
+## 3. Documentation Standards
+
+### README Files
+Structure (in order):
+1. `# Title` — project name, one-line tagline
+2. Badges (if applicable: build status, coverage, PyPI version)
+3. **Description** — what it does and why it exists (3-5 sentences)
+4. **Installation** — step-by-step, assume fresh environment
+5. **Usage** — most common use case first, with code examples
+6. **Configuration** — environment variables, config files (if applicable)
+7. **Examples** — additional usage patterns
+8. **Development** — how to run tests, contribute
+9. **License** (if applicable)
+
+Do NOT write marketing fluff. Be concise and technical.
+
+### Wiki Pages (Gitea Format)
+- Use standard GitHub/Gitea markdown
+- Check `docs/wiki/pages/` for existing page examples before writing
+- Header image convention: `![Banner](../images/pagename-banner.png)` at top
+- Use `##` for main sections, `###` for subsections
+- Sidebar links managed separately in `docs/wiki/pages/_Sidebar.md`
+- Keep page titles matching filename (e.g., `MCP-Servers-Overview.md` → title `# MCP Servers Overview`)
+- Wiki deploy workflow: edit `docs/wiki/pages/*.md` → run `./docs/wiki/deploy_wiki.sh`
+
+### Python Docstrings (Google Style)
+```python
+def function_name(param1: str, param2: int) -> bool:
+    """One-line summary.
+
+    Longer description if needed. Explain what the function does,
+    not how it does it.
+
+    Args:
+        param1: Description of param1.
+        param2: Description of param2.
+
+    Returns:
+        True if successful, False otherwise.
+
+    Raises:
+        ValueError: If param1 is empty.
+        RuntimeError: If the operation fails.
+
+    Example:
+        >>> function_name("hello", 42)
+        True
+    """
+```
+
+### Java Javadoc
+```java
+/**
+ * One-line summary.
+ *
+ * <p>Longer description if needed. Explain behavior and side effects.
+ *
+ * @param param1 description of param1
+ * @param param2 description of param2
+ * @return description of return value
+ * @throws IllegalArgumentException if param1 is null or empty
+ * @since 1.0
+ */
+```
+
+### Changelogs (Keep a Changelog Format)
+```markdown
+# Changelog
+
+## [Unreleased]
+
+## [1.2.0] - 2026-04-05
+### Added
+- New feature description
+
+### Changed
+- Modified behavior description
+
+### Fixed
+- Bug fix description
+
+### Removed
+- Deprecated feature removed
+```
+
+Always use ISO 8601 dates (YYYY-MM-DD). Follow keepachangelog.com conventions exactly.
+
+### Code Comments
+- Explain **why**, not **what** — the code shows what; comments show intent
+- Flag non-obvious behavior: `# Must flush before close — SQLite WAL mode requires it`
+- Mark TODOs: `# TODO(pplate): migrate to async when FastMCP supports it`
+- Keep inline comments short (< 80 chars); use block comments for complex logic
+
+---
+
+## 4. Output Directly
+
+**Write the document. Don't explain what you're about to write.**
+
+❌ Bad: "I'll write a README for your MCP server. Here's what I'll include..."
+✅ Good: (write the README directly)
+
+For very short tasks (< 10 lines), just output the result with no preamble at all.
+
+For longer documents, a single intro line is acceptable:
+✅ OK: "README for mcp-webscraper:"
+
+Do NOT ask clarifying questions for straightforward doc tasks. Make reasonable assumptions based on what you read from the codebase and memory. If genuinely ambiguous (e.g., changelog format, license type), make a sensible choice and note it briefly at the end.
+
+---
+
+## 5. Token Efficiency
+
+Before reading any file for context, check memory:
+1. `memory_search_facts("project conventions")` — often has the answer
+2. `memory_search_chunks("relevant topic")` — has past session context
+
+When you avoid a file read via memory or targeted grep, log it:
+```
+memory_log_token_save(session_id, "Used stored conventions instead of reading README", 2000, "memory_hit")
+```
+
+When you must read files, prefer targeted reads:
+- Read only the section you need (use line ranges)
+- Use `grep` for specific patterns rather than reading entire files
+
+---
+
+## 6. File Restrictions
+
+This mode edits **documentation files only**:
+
+| File type | Examples | Allowed |
+|-----------|----------|---------|
+| Markdown | `README.md`, `CHANGELOG.md`, `docs/**/*.md` | ✅ |
+| reStructuredText | `*.rst` | ✅ |
+| Plain text | `*.txt` | ✅ |
+| Python (docstrings only) | `*.py` | ✅ read + limited edit |
+| Java (Javadoc only) | `*.java` | ✅ read + limited edit |
+| Wiki pages | `docs/wiki/pages/*.md` | ✅ |
+
+**Do NOT**:
+- Implement features in `.py` or `.java` files
+- Fix bugs in source code
+- Modify configuration files (`.yaml`, `.json`, `.toml`, `pyproject.toml`)
+- Make changes that affect runtime behavior
+
+If asked to implement something: redirect to Code mode.

+# CannaManage — Project Charter
+
+**Author:** Patrick Plate  
+**Date:** 2026-04-06  
+**Version:** 1.0  
+**Status:** Draft for Review
+
+---
+
+## 1. Executive Summary
+
+### Vision Statement
+
+> *CannaManage is the compliance backbone for German cannabis social clubs — purpose-built to turn a legally mandated administrative burden into a manageable, auditable, and digitised workflow.*
+
+### The Problem
+
+Germany's **Konsumcannabisgesetz (CanG)**, in force since April 1, 2024, legalised cannabis for personal use and established a framework for **Anbauvereinigungen** (cannabis social clubs / CSCs). Every operating CSC faces mandatory, recurring compliance obligations:
+
+- Track every distribution (recipient, strain, weight, date/time) — by law
+- Enforce quantity limits per member (50g/month for adults, 30g/month for under-21, 25g/day)
+- Maintain batch-level contamination traceability
+- Produce periodic authority reports
+- Designate and track a Prevention Officer (Präventionsbeauftragter)
+- Manage member data under DSGVO
+
+Clubs currently manage this with Excel spreadsheets, pen-and-paper logs, and WhatsApp groups — creating legal risk, audit gaps, and administrative chaos.
+
+### Why Now
+
+The market is less than two years old. **No purpose-built software tooling exists** for German CSCs. The window to establish market leadership is 2026–2027 before larger players notice the niche. First-mover advantage combined with the permanent regulatory moat from CanG compliance requirements makes this the right moment.
+
+### What We Are Building
+
+A **multi-tenant B2B SaaS platform** offering:
+- Club admin portal (member management, distribution logging, stock management, compliance reporting)
+- Member portal (personal quota, distribution history, stock visibility)
+- Built-in CanG compliance enforcement and export tooling
+
+**We are selling compliance management software to licensed, regulated entities. We are not in the cannabis business.**
+
+---
+
+## 2. Project Scope
+
+### 2.1 In Scope — MVP v1
+
+| Area | Features Included |
+|------|-------------------|
+| **Onboarding** | Club registration, setup wizard, admin account creation |
+| **Member Management** | Add/remove members, age verification (18+, 18–21 restricted), contact data |
+| **Distribution Tracking** | Log each handout (member, strain, weight, date/time); enforce daily/monthly limits |
+| **Limit Enforcement** | 25g/day cap, 50g/month (adult), 30g/month (under-21), 10% THC flag |
+| **Stock Management** | Strains, batch tracking, quantity levels |
+| **Admin Dashboard** | Club-level totals: members, distributions this month, stock levels |
+| **Compliance Exports** | Monthly distribution report (PDF + CSV), member list export for inspections |
+| **Contamination Recall** | Flag a batch; system lists all members who received from it |
+| **Prevention Officer** | Store officer contact info and designation date |
+| **Member Portal** | Login with club-issued credentials; view quota, distribution history, stock availability |
+| **Authentication** | Spring Security + JWT; role-based (ADMIN, MEMBER) |
+| **Hosting** | Hetzner VPS (German DC), Docker Compose, PostgreSQL + Flyway |
+
+### 2.2 Explicitly Out of Scope — MVP v1
+
+| Feature | Reason Excluded |
+|---------|-----------------|
+| Public club discovery / "find clubs near you" | **Illegal under CanG §§6–7 advertising ban** |
+| Cannabis e-commerce or payment for cannabis | Illegal; violates positioning |
+| Non-EU data storage (AWS us-east, etc.) | DSGVO violation |
+| Stripe subscription billing | Deferred to Phase 1 (Weeks 9–16) |
+| Email/SMS notifications | v2 feature |
+| Mobile native app (Android/iOS) | v2/v3 feature |
+| Multi-location club support | v3 feature |
+| Legal template marketplace | v3 feature |
+| Next.js/React frontend | v2 migration after revenue justifies investment |
+| Authority portal integrations | v3 feature (portals don't exist yet) |
+
+---
+
+## 3. Stakeholders
+
+| Role | Description | Needs |
+|------|-------------|-------|
+| **Club Admin** *(primary user)* | Vereinsvorstand or designated manager; runs day-to-day club operations | Compliant distribution logging, member management, authority-ready exports |
+| **Club Member** *(secondary user)* | Verified adult member of the Anbauvereinigung | Self-service quota visibility, distribution history, stock availability |
+| **Prevention Officer** *(Präventionsbeauftragter, tertiary user)* | Legally required role; may or may not be the admin | Contact info tracked in system; receives relevant reports |
+| **Patrick Plate** *(developer & product owner)* | Solo developer; nights/weekends; ADP Germany full-time | Minimal learning overhead; fast path to first revenue; legally sound product |
+
+---
+
+## 4. Success Criteria
+
+MVP is considered complete when all of the following are true:
+
+| # | Criterion | Measure |
+|---|-----------|---------|
+| 1 | **Core compliance loop working** | Admin can log a distribution → system enforces limits → admin exports PDF report for authorities |
+| 2 | **Multi-tenant isolation** | Two clubs' data are completely isolated — no cross-tenant data leakage |
+| 3 | **Member portal live** | Member can log in with club-issued credentials and view their quota + history |
+| 4 | **Contamination recall functional** | Admin flags a batch; system returns full recipient list in < 2 seconds |
+| 5 | **Deployment stable** | Platform runs on Hetzner VPS via Docker Compose with uptime ≥ 99% over 30-day beta |
+| 6 | **Beta validation** | 3–5 real club admins have used the system and provided written feedback |
+| 7 | **Legal review passed** | No features violate CanG advertising ban; DSGVO AVV in place before any live data |
+| 8 | **Zero PII on non-EU infrastructure** | All data confirmed to reside in Hetzner DE datacenter |
+
+---
+
+## 5. Constraints & Assumptions
+
+### Constraints
+
+| Type | Constraint |
+|------|-----------|
+| **Legal** | CanG §§6–7 imposes a **total advertising and sponsoring ban** on cannabis AND Anbauvereinigungen — no public club discovery feature, ever |
+| **Legal** | DSGVO requires EU hosting, data processing agreements (AVV), member data export/deletion capability |
+| **Technical (MVP)** | Frontend is PrimeFaces + JSF — Patrick's existing expertise; no new framework learning in Phase 0 |
+| **Technical** | Multi-tenancy via `tenant_id` on all JPA entities — no row-level security shortcuts |
+| **Team** | Solo developer — Patrick; nights and weekends only; full-time at ADP Germany |
+| **Timeline** | Phase 0 target: 8 weeks; Phase 1 target: 16 weeks total from project start |
+| **Budget** | Infrastructure: Hetzner €5–20/month; no team salary cost |
+
+### Assumptions
+
+- German CSCs are willing to pay €29–€79/month for compliance software
+- Stripe will process subscriptions for compliance software (not cannabis sales) without restriction
+- Spring Boot 3.x is sufficiently adjacent to Patrick's Jakarta EE expertise to use without major ramp-up
+- PrimeFaces MVP is sufficient for beta validation — UI polish deferred to v2
+- CanG remains in force and CSC licensing continues in all major Bundesländer
+
+---
+
+## 6. Risk Register
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|-----------|
+| **Advertising ban reinterpreted to include B2B SaaS** | Low | High | Obtain legal opinion from cannabis law specialist before launch (€300–500); strict no-discovery design enforced at architecture level |
+| **New German government rolls back or tightens CanG** | Medium | High | Modular architecture — compliance-only features can be extracted and pivoted to a general club management tool |
+| **Stripe blocks cannabis-adjacent businesses** | Medium | High | Position as "Vereinsverwaltungs-Software" (club management software); never process cannabis payments; test with Stripe before public launch |
+| **Clubs fail / licenses revoked** | Medium | Medium | Diversified customer base; per-month billing (easy cancellation); no annual lock-in required for MVP |
+| **DSGVO violation** | Low | Very High | EU-only hosting (Hetzner DE), DPA/AVV agreements before any live data, DSGVO-compliant privacy policy in German, member data export/deletion API from day one |
+
+---
+
+## 7. Budget & Resources
+
+| Item | Cost | Notes |
+|------|------|-------|
+| **Development** | €0 (Patrick's time) | Nights/weekends; valued at opportunity cost only |
+| **Infrastructure — Hetzner VPS** | €5–20/month | German DC; scales with load |
+| **Infrastructure — PostgreSQL** | €0 (self-hosted on VPS) | Managed DB upgrade available when needed |
+| **Legal opinion** | €300–500 (one-time) | Cannabis law specialist; pre-launch requirement |
+| **Domain (cannamanage.de)** | ~€15/year | To be registered |
+| **Stripe fees** | 1.4% + €0.25 per transaction | EU cards; only on paid subscriptions |
+| **Email (Resend / Jakarta Mail)** | €0–10/month | Resend free tier for low volume |
+| **Sentry monitoring** | €0 (free tier) | Error tracking; Java SDK |
+| **Total pre-launch** | **~€600–700** | Including legal opinion |

+
+### Key CanG Provisions
+
+| Provision | Content | Product Implication |
+|-----------|---------|---------------------|
+| **§2 CanG** | Definitions — Anbauvereinigung, Mitglied | Data model must align with statutory definitions of club and member |
+| **§§15–26 CanG** | Anbauvereinigungen — formation, rights, obligations | Club registration flow must capture legally required club attributes |
+| **§22 CanG** | Distribution limits: 25g/day, 50g/month per adult member | Hard enforcement in distribution service; cannot be overridden by admin |
+| **§23 CanG** | Under-21 restrictions: 30g/month max, max 10% THC | Age flag on member entity; separate limit enforcement path for restricted category |
+| **§§6–7 CanG** | **Total advertising and sponsoring ban** for cannabis and Anbauvereinigungen | **No public club discovery. No stock visible to non-members. No club listings.** Architecture constraint. |
+| **§26 CanG** | Documentation and reporting obligations | Compliance export module is a legal requirement, not an optional feature |

+## Must Have — MVP v1
+
+### Club Admin Stories
+
+---
+
+### US-001: Register Club and Complete Setup Wizard
+
+**As a** Club Admin, **I want to** register my Anbauvereinigung and complete a guided setup wizard, **so that** my club is correctly configured with all legally required attributes before any members are added.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can register with email + password; email confirmation required before accessing the system
+- [ ] AC2: Setup wizard collects: club name, registered address, founding date, Vereinsregisternummer (if available), maximum membership count
+- [ ] AC3: Wizard requires designation of a Prevention Officer (name, contact) — field is mandatory, cannot be skipped
+- [ ] AC4: Wizard requires acceptance of DSGVO data processing agreement (AVV) before any member data can be entered
+- [ ] AC5: Completing the wizard provisions the club's isolated tenant environment (all subsequent data scoped to this club only)
+- [ ] AC6: Admin receives a welcome email with login link after successful setup
+- [ ] AC7: Incomplete wizard state is saved — admin can resume from last completed step
+
+**Notes:** The AVV acceptance (AC4) is a legal prerequisite for handling member personal data under DSGVO. It must be timestamped and stored.
+
+---
+
+### US-002: Add and Remove Members with Age Verification
+
+**As a** Club Admin, **I want to** add and remove club members with age verification, **so that** the member roster is accurate and the system can apply the correct distribution limits per member.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can add a member with: full name, date of birth, email (optional), membership start date, member ID (auto-generated or manual)
+- [ ] AC2: System rejects members with date of birth indicating age < 18
+- [ ] AC3: Members aged 18–21 are automatically flagged as "Restricted (§23 CanG)" — this flag drives reduced quantity limits
+- [ ] AC4: Admin can deactivate (soft-delete) a member; deactivated members cannot receive distributions but their historical records are preserved
+- [ ] AC5: Admin can permanently delete a member record (DSGVO Art. 17 right to erasure); system warns if member has distribution history and requires explicit confirmation
+- [ ] AC6: Member list is searchable by name and filterable by status (active / restricted / deactivated)
+- [ ] AC7: Total active member count is visible on the dashboard and in the member list header
+
+**Notes:** Hard deletion (AC5) must cascade correctly — distribution records referencing the member must be anonymised, not deleted, to preserve the compliance audit trail.
+
+---
+
+### US-003: Record a Distribution
+
+**As a** Club Admin, **I want to** record each cannabis distribution to a member, **so that** every handout is documented as required by §26 CanG and the member's consumption is tracked.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can log a distribution by selecting: member (search/autocomplete), strain, weight in grams (decimal, e.g. 3.5g), batch, date and time
+- [ ] AC2: System pre-fills date/time with current timestamp; admin can override
+- [ ] AC3: If the distribution would cause the member to exceed their daily limit (25g), the system displays a prominent warning and requires explicit override confirmation
+- [ ] AC4: If the distribution would cause the member to exceed their monthly limit (50g adult / 30g restricted), the system **blocks** the entry and displays the reason
+- [ ] AC5: For restricted members (§23), system additionally validates that the selected strain's THC percentage is ≤ 10% (if THC% is recorded on the batch)
+- [ ] AC6: Successfully saved distributions appear immediately in the distribution log and update the member's monthly counter
+- [ ] AC7: Distribution records are immutable after creation — admin can only add a correction note, not edit the original record
+
+**Notes:** Immutability (AC7) is essential for audit integrity. Correction notes are the appropriate mechanism for errors.
+
+---
+
+### US-004: View and Enforce Distribution Limits
+
+**As a** Club Admin, **I want to** view each member's current distribution totals and remaining quota, **so that** I can verify limits at a glance before and after recording distributions.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Each member's detail view shows: distributions this month (total grams), daily total for today, remaining monthly quota, and limit category (Adult 50g / Restricted 30g)
+- [ ] AC2: Remaining quota is displayed as a progress bar (visual indicator of how close to the limit)
+- [ ] AC3: Members who have reached or exceeded their monthly limit are visually flagged in the member list (e.g., red badge)
+- [ ] AC4: Members who have consumed > 80% of their monthly limit show a warning indicator (e.g., amber badge)
+- [ ] AC5: Monthly counters reset automatically on the first of each calendar month
+- [ ] AC6: System applies §22 limits (50g/month, 25g/day) for adults and §23 limits (30g/month) for restricted members — these cannot be changed by the admin
+
+**Notes:** The limits in AC6 are statutory and must be hardcoded, not configurable per club.
+
+---
+
+### US-005: Manage Stock (Strains, Quantities, Batches)
+
+**As a** Club Admin, **I want to** manage my club's cannabis stock including strains, batch information, and quantities, **so that** I know what is available for distribution and can track batch provenance for contamination purposes.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can create a strain with: name, THC% (optional), CBD% (optional), variety type (Indica/Sativa/Hybrid)
+- [ ] AC2: Admin can create a batch linked to a strain with: batch ID (auto-generated), quantity in grams, harvest date (optional), grow cycle reference (optional)
+- [ ] AC3: Each distribution recorded reduces the associated batch's available quantity
+- [ ] AC4: Admin can manually adjust stock quantity with a reason note (e.g., "lab sample", "disposal")
+- [ ] AC5: Admin is warned (but not blocked) when a batch's available quantity drops below a configurable threshold (default: 100g)
+- [ ] AC6: Stock overview page shows all active batches with: strain name, batch ID, quantity available, quantity distributed to date
+- [ ] AC7: Depleted batches (quantity = 0) are automatically moved to an "archived" view
+
+**Notes:** Batch tracking is required for contamination recall (US-009). The batch ID must be immutable once created.
+
+---
+
+### US-006: View Admin Dashboard
+
+**As a** Club Admin, **I want to** see a summary dashboard when I log in, **so that** I have an at-a-glance overview of club activity and can identify anything requiring attention.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Dashboard displays: total active members, members at/near their monthly limit (count), total distributions this calendar month (grams), active stock level (total grams across all batches)
+- [ ] AC2: Dashboard shows a count of members in the "restricted §23" category separately
+- [ ] AC3: Dashboard highlights any batches flagged as contaminated (contamination alert count)
+- [ ] AC4: Dashboard includes a recent activity feed (last 10 distributions: member name, strain, weight, time)
+- [ ] AC5: All dashboard data reflects the admin's own club only — never cross-tenant data
+- [ ] AC6: Dashboard loads in < 3 seconds on Hetzner VPS hardware
+
+**Notes:** Keep the dashboard simple for MVP — a single page with widgets. No charts required for v1.
+
+---
+
+### US-007: Export Monthly Compliance Report (PDF + CSV)
+
+**As a** Club Admin, **I want to** export a monthly compliance report as PDF and CSV, **so that** I can fulfil my documentation and reporting obligations under §26 CanG.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can select any calendar month/year and generate a compliance report
+- [ ] AC2: PDF report contains: club name, reporting period, total distributions (count and weight), distribution detail table (member ID, strain, batch, weight, date/time), stock summary
+- [ ] AC3: Member names in the PDF are replaced with member IDs to minimise PII exposure in the report document (actual name lookup available to the club separately)
+- [ ] AC4: CSV export contains full distribution log for the selected period with headers: member_id, strain, batch_id, weight_g, distribution_date, distribution_time
+- [ ] AC5: PDF is generated server-side using iText 7 (no client-side rendering dependency)
+- [ ] AC6: Export completes in < 10 seconds for a month with up to 5,000 distribution records
+- [ ] AC7: Generated reports are not stored on the server — they are streamed directly to the browser as a download
+
+**Notes:** Not storing reports (AC7) reduces data exposure risk. The club is responsible for retaining their own copies.
+
+---
+
+### US-008: Export Member List for Inspections
+
+**As a** Club Admin, **I want to** export the current member list, **so that** I can present it to authorities during an inspection as required by law.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can export the active member list as PDF and CSV at any time
+- [ ] AC2: Export includes: member ID, full name, date of birth, age category (Adult/Restricted §23), membership start date, current membership status
+- [ ] AC3: Export is timestamped with the generation date/time in the document
+- [ ] AC4: Admin is shown a DSGVO reminder before downloading (this document contains personal data — handle per your privacy obligations)
+- [ ] AC5: Export includes the club name and address in the header
+- [ ] AC6: Only active members are included by default; admin can optionally include deactivated members
+
+**Notes:** This document contains significant PII. The DSGVO reminder (AC4) is important to keep admins legally aware.
+
+---
+
+### US-009: Trigger Contamination Alert for a Batch
+
+**As a** Club Admin, **I want to** flag a batch as contaminated and immediately see all members who received from it, **so that** I can notify affected members and fulfil my contamination traceability obligations under CanG.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can mark any batch as "contaminated" with a reason note and timestamp
+- [ ] AC2: Immediately upon flagging, system displays a list of all members who received distributions from the contaminated batch (name, member ID, total grams received, dates received)
+- [ ] AC3: Contaminated batches are removed from the active distribution interface — admin cannot select them for new distributions
+- [ ] AC4: The dashboard shows a contamination alert badge whenever any active batch is flagged
+- [ ] AC5: Admin can export the affected member list as PDF and CSV (for authority notification)
+- [ ] AC6: Contamination status is immutable — once flagged, only a senior action (with confirmation) can reverse it; reversal is logged with reason
+
+**Notes:** Contamination traceability is explicitly required by CanG. Response speed matters — the affected member list (AC2) must display without delay.
+
+---
+
+### US-010: Manage Prevention Officer Information
+
+**As a** Club Admin, **I want to** record and update Prevention Officer (Präventionsbeauftragter) information, **so that** my club meets the mandatory requirement of §27 CanG.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Club profile includes a Prevention Officer section with fields: full name, contact email, contact phone, designation date
+- [ ] AC2: All four fields are required — the system warns if any is empty and marks the section as incomplete
+- [ ] AC3: Admin can update the Prevention Officer at any time; previous officer entries are retained in a change log (name, designation period)
+- [ ] AC4: The compliance report export (US-007) includes the current Prevention Officer name and contact in its header
+- [ ] AC5: Setup wizard (US-001) cannot be completed without entering Prevention Officer information
+
+**Notes:** This is a statutory requirement, not optional. AC5 enforces that clubs cannot operate on the platform without this data.
+
+---
+
+### Member Portal Stories
+
+---
+
+### US-011: Login with Club-Issued Credentials
+
+**As a** Club Member, **I want to** log in to the member portal using credentials issued by my club, **so that** I can access my personal information without the club admin needing to be present.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can generate login credentials (username + temporary password) for a member from the member management screen
+- [ ] AC2: Member receives credentials via a secure channel (displayed to admin for manual handoff in MVP; email in v2)
+- [ ] AC3: Member is required to change their temporary password on first login
+- [ ] AC4: Member login is scoped to their club only — they cannot access any other club's data or member list
+- [ ] AC5: Failed login attempts are rate-limited (5 attempts, then 15-minute lockout)
+- [ ] AC6: Member sessions expire after 24 hours of inactivity
+- [ ] AC7: Members cannot register themselves — accounts are always created by the Club Admin
+
+**Notes:** AC7 is critical for CanG compliance — only verified, age-checked members should have portal access.
+
+---
+
+### US-012: View Personal Distribution History
+
+**As a** Club Member, **I want to** view my personal distribution history, **so that** I can track what I have received from the club.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member can view all their distributions in reverse chronological order: date/time, strain, weight (grams), batch ID
+- [ ] AC2: Current calendar month distributions are shown first, with a clear monthly subtotal
+- [ ] AC3: Member can filter history by month/year
+- [ ] AC4: Member sees only their own distribution history — no other member's data is accessible
+- [ ] AC5: History is read-only — members cannot edit or delete distribution records
+
+---
+
+### US-013: View Current Stock Availability
+
+**As a** Club Member, **I want to** see what strains are currently available at the club, **so that** I know what I can request on my next visit.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member portal shows a stock list with: strain name, variety type (Indica/Sativa/Hybrid), THC% (if recorded), availability status (Available / Low Stock / Unavailable)
+- [ ] AC2: Exact batch quantities are NOT shown to members — only availability status
+- [ ] AC3: Only strains with available stock (quantity > 0) are shown as "Available"
+- [ ] AC4: Strains with stock below the admin-configured low-stock threshold are shown as "Low Stock"
+- [ ] AC5: For restricted members (§23 CanG), strains with THC > 10% are shown with a "Not available to you" indicator rather than hidden (transparency about why)
+- [ ] AC6: Stock view is refreshed in real time — no stale cache longer than 5 minutes
+
+**Notes:** AC2 is important — showing exact quantities could constitute advertising for the club's stock. Only availability status is shown.
+
+---
+
+### US-014: View Remaining Monthly Quota
+
+**As a** Club Member, **I want to** see my remaining monthly quota, **so that** I can plan my distributions and stay within my legal limits.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member portal homepage prominently displays: consumed this month (grams), remaining quota (grams), monthly limit (grams), days remaining in current month
+- [ ] AC2: Quota is displayed as a progress bar with colour coding: green (< 50% used), amber (50–80% used), red (> 80% used)
+- [ ] AC3: Members in the restricted §23 category see their 30g/month limit (not the 50g adult limit)
+- [ ] AC4: Daily limit status is also visible: consumed today (grams) vs. 25g daily cap
+- [ ] AC5: Quota resets display on the first of each calendar month — confirmed visually (e.g., "Resets in X days")
+
+---
+
+## Should Have — v2
+
+---
+
+### US-015: Process Membership Fee Payments via Stripe
+
+**As a** Club Admin, **I want to** collect membership fees from members via Stripe, **so that** fee collection is automated and documented without manual bank transfers.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can configure an annual membership fee amount for their club
+- [ ] AC2: Members can pay via Stripe-hosted checkout (card payment)
+- [ ] AC3: Stripe subscription or one-time payment for annual fee — admin configures which model
+- [ ] AC4: Payment confirmation is logged against the member record with date and amount
+- [ ] AC5: Admin can view payment status per member (paid / pending / overdue)
+- [ ] AC6: No cannabis product payments are ever processed through this system — fee is for club membership only
+
+**Notes:** Stripe position: membership fees for registered non-profit clubs (Vereinsbeiträge) are standard use case. AC6 must be enforced at system design level.
+
+---
+
+### US-016: Manage Automated Waiting List
+
+**As a** Club Admin, **I want to** manage a waiting list for new membership applicants, **so that** I can process applications in order while respecting the club's maximum membership count.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can set a maximum member count for the club (from setup wizard or settings)
+- [ ] AC2: When member count reaches maximum, new applicants are added to a waiting list with timestamp
+- [ ] AC3: Waiting list is FIFO — applicants are offered membership in order of application
+- [ ] AC4: Admin can notify the next waiting list applicant (email notification — v2 dependency)
+- [ ] AC5: Admin can remove applicants from the waiting list
+- [ ] AC6: Waiting list count is visible on the admin dashboard
+
+---
+
+### US-017: Receive Email and SMS Notifications
+
+**As a** Club Member, **I want to** receive email (and optionally SMS) notifications for key events, **so that** I am informed without needing to log in to the portal.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member receives email notification when their distribution is recorded by the admin
+- [ ] AC2: Member receives email when their monthly quota reaches 80% consumed
+- [ ] AC3: Member receives email when a batch they received from is flagged as contaminated
+- [ ] AC4: Admin receives email when any member's quota is exceeded (should not happen, but safety net)
+- [ ] AC5: SMS notifications are optional and require member opt-in; email is default
+- [ ] AC6: All notification emails are sent in German (language is not configurable in v2)
+- [ ] AC7: Members can manage notification preferences (opt out of non-mandatory notifications)
+
+---
+
+### US-018: Track Multi-Strain Grow Cycles
+
+**As a** Club Admin, **I want to** track grow cycles linked to batches, **so that** I have full provenance from grow start to distribution.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can create a grow cycle with: cycle ID, strain, start date, expected harvest date, grow area (optional), notes
+- [ ] AC2: Batches can be linked to a grow cycle
+- [ ] AC3: Grow cycle view shows: all batches produced, total yield, grow duration
+- [ ] AC4: Closed grow cycles (harvest complete) are archived but remain searchable
+- [ ] AC5: Grow cycle data is included in the monthly compliance report (batch provenance section)
+
+---
+
+## Could Have — v3
+
+---
+
+### US-019: Access Mobile PWA
+
+**As a** Club Member, **I want to** use CannaManage on my smartphone without installing an app, **so that** I can check my quota and stock on the go.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: The member portal is fully responsive and usable on mobile viewport sizes (320px and up)
+- [ ] AC2: The app can be added to the home screen (PWA manifest, service worker, offline cache for quota display)
+- [ ] AC3: Core member portal features (quota, distribution history, stock view) work in offline mode with cached data
+- [ ] AC4: Admin portal is also responsive (admin-on-the-go distribution logging)
+- [ ] AC5: No app store submission required — pure PWA
+
+---
+
+### US-020: Support Multi-Location Club
+
+**As a** Club Admin, **I want to** manage a club with multiple distribution locations, **so that** members can pick up from different sites and all distributions are consolidated.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can define multiple locations (name, address) for one club
+- [ ] AC2: Distributions are recorded with a location tag
+- [ ] AC3: Stock is managed per location or shared — admin configures which model
+- [ ] AC4: Compliance reports can be generated per location or consolidated for the whole club
+- [ ] AC5: Members are assigned a primary location but can receive from any location within quota limits
+
+---
+
+### US-021: Download Legal Document Templates
+
+**As a** Club Admin, **I want to** download standardised legal document templates (Satzung, Jugendschutzkonzept), **so that** I can fulfil my legal obligations without hiring a lawyer for every document.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: Template library is accessible from the admin portal (separate from compliance exports)
+- [ ] AC2: Available templates include: Vereinssatzung (club charter), Jugendschutzkonzept (youth protection concept), DSGVO Datenschutzerklärung
+- [ ] AC3: Templates are pre-filled with club-specific data (name, address, Prevention Officer) where applicable
+- [ ] AC4: Templates are available as DOCX (editable) and PDF (final version)
+- [ ] AC5: Template library is a paid add-on (€49 one-time or included in Professional/Enterprise plan)
+
+---
+
+### US-022: Integrate with Authority Reporting Portals
+
+**As a** Club Admin, **I want to** submit compliance reports directly to authority portals via CannaManage, **so that** I save time and avoid transcription errors in authority submissions.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: System can detect available authority portals by Bundesland (state)
+- [ ] AC2: Admin can initiate a report submission from within CannaManage
+- [ ] AC3: Submission status is tracked (submitted, acknowledged, rejected) per report
+- [ ] AC4: System retries failed submissions automatically (up to 3 times)
+- [ ] AC5: This feature is only activated once at least one Bundesland has a machine-readable submission portal
+
+**Notes:** Authority portals may not exist in v3 timeline — this is aspirational and depends on government digitalisation progress.
+
+---
+
+## Won't Have — MVP (Explicitly Excluded)
+
+---
+
+### US-023: Public Club Discovery — "Find Clubs Near You"
+
+**As a** Public User, I want to find cannabis clubs near my location.
+
+**Priority:** Won't Have (MVP)  
+**Reason:** **Explicitly illegal under CanG §§6–7.** The advertising and sponsoring ban covers any feature that functions as advertising for Anbauvereinigungen to the general public. A public club directory constitutes advertising for clubs. This feature will never be built in any form on this platform.
+
+**Acceptance Criteria:** *None — this feature is permanently excluded.*
+
+**Notes:** This is not a commercial decision. It is a **legal constraint** hardcoded into the product architecture. No public-facing club listing, no map, no search, no "register your club publicly."
+
+---
+
+### US-024: Cannabis E-Commerce or Payment for Cannabis Products
+
+**As a** Club Member, I want to purchase cannabis through the CannaManage platform.
+
+**Priority:** Won't Have (MVP)  
+**Reason:** **Illegal.** Cannabis sales are not the legal model for Anbauvereinigungen under CanG. Payment for cannabis products would violate German law and immediately trigger Stripe account termination. CannaManage processes membership fee payments only — not cannabis product payments, ever.
+
+**Acceptance Criteria:** *None — permanently excluded.*
+
+---
+
+### US-025: Non-EU Data Storage
+
+**As a** Club Admin, I want my club's data stored on the cheapest/fastest infrastructure, including non-EU servers.
+
+**Priority:** Won't Have (MVP)  
+**Reason:** **DSGVO violation.** Club member data includes personal data (name, date of birth, consumption records). Storing this outside the EU without a valid adequacy decision or standard contractual clauses violates Art. 44–49 DSGVO. All data remains on Hetzner DE datacenters.
+
+**Acceptance Criteria:** *None — permanently excluded.*
+
+---

+
+## 2. Multi-Tenancy Strategy
+
+### Approach: Shared Schema with Row-Level Filtering
+
+Every JPA entity carries a `tenant_id` column (UUID, `NOT NULL`). A single PostgreSQL database hosts all clubs — row-level filtering enforces data isolation at the application layer.
+
+**Why shared schema (not separate schema/DB per tenant)?**
+- Lower operational overhead for an MVP with < 500 clubs
+- Single Flyway migration path across all tenants
+- Simpler connection pooling (one pool, not N)
+- Acceptable security risk when `tenant_id` filter is enforced at the service layer
+
+### Tenant Resolution
+
+```
+HTTP Request
+    └─ Spring Security Filter: extract JWT → resolve tenant_id
+         └─ TenantContext.setCurrentTenant(tenantId)   // ThreadLocal
+              └─ JPA @Where filter applied on every entity query
+```
+
+### Code Pattern — Tenant-Aware Base Entity
+
+```java
+// AbstractTenantEntity.java (pseudocode)
+@MappedSuperclass
+@FilterDef(
+    name = "tenantFilter",
+    parameters = @ParamDef(name = "tenantId", type = UUID.class)
+)
+@Filter(name = "tenantFilter", condition = "tenant_id = :tenantId")
+public abstract class AbstractTenantEntity {
+
+    @Column(name = "tenant_id", nullable = false, updatable = false)
+    private UUID tenantId;
+
+    @PrePersist
+    void injectTenant() {
+        this.tenantId = TenantContext.getCurrentTenant();
+    }
+}
+```
+
+```java
+// TenantFilterInterceptor.java (pseudocode)
+@Component
+public class TenantFilterInterceptor implements HandlerInterceptor {
+
+    @Autowired EntityManager em;
+
+    @Override
+    public boolean preHandle(HttpServletRequest req, ...) {
+        UUID tenantId = TenantContext.getCurrentTenant();
+        Session session = em.unwrap(Session.class);
+        session.enableFilter("tenantFilter")
+               .setParameter("tenantId", tenantId);
+        return true;
+    }
+}
+```
+
+**Invariants enforced:**
+- `tenant_id` is set at `@PrePersist` — never accepted from user input
+- `tenant_id` is `updatable = false` — cannot be changed after creation
+- Hibernate filter is enabled on every request thread before any query executes
+- All repository methods inherit the filter; raw JPQL queries must include `AND e.tenantId = :tenantId`
+
+---
+
+## 3. Authentication & Authorization
+
+### JWT Token Flow
+
+- **Access token:** 8-hour expiry, signed HS256, contains `sub` (userId), `role`, `tenantId`
+- **Refresh token:** 30-day expiry, stored in `users.refresh_token_hash` (hashed)
+- **Stateless:** No server-side session. JWT is verified on every request by `JwtAuthFilter`
+
+### Roles
+
+| Role | Description | Access |
+|---|---|---|
+| `ROLE_CLUB_ADMIN` | Club administrator | Full club management, all members, reports, distributions |
+| `ROLE_MEMBER` | Club member | Own quota, own distribution history |
+| `ROLE_PREVENTION_OFFICER` | Designated prevention officer | Member under-21 reports, prevention data |
+
+### Service-Layer Authorization Example
+
+```java
+@Service
+public class DistributionService {
+
+    @PreAuthorize("hasRole('CLUB_ADMIN')")
+    public Distribution recordDistribution(RecordDistributionRequest req) { ... }
+
+    @PreAuthorize("hasRole('MEMBER') and #memberId == authentication.principal.memberId")
+    public QuotaStatus getMyQuota(UUID memberId) { ... }
+
+    @PreAuthorize("hasAnyRole('CLUB_ADMIN', 'PREVENTION_OFFICER')")
+    public List<Member> getUnder21Members() { ... }
+}
+```
+
+### Member Login Sequence
+
+```mermaid
+sequenceDiagram
+    participant B as Browser
+    participant API as Spring Boot /api/v1/auth/login
+    participant DB as PostgreSQL (users table)
+    participant JWT as JwtService
+
+    B->>API: POST /api/v1/auth/login {email, password}
+    API->>DB: SELECT * FROM users WHERE email = ? AND active = true
+    DB-->>API: UserEntity (password_hash, role, tenant_id, member_id)
+    API->>API: BCrypt.verify(password, password_hash)
+    alt Invalid credentials
+        API-->>B: 401 Unauthorized
+    else Valid
+        API->>JWT: generateAccessToken(userId, role, tenantId) → 8h
+        API->>JWT: generateRefreshToken(userId) → 30d
+        API->>DB: UPDATE users SET refresh_token_hash = ?, last_login = NOW()
+        DB-->>API: OK
+        JWT-->>API: accessToken, refreshToken
+        API-->>B: 200 { accessToken, refreshToken, expiresIn: 28800 }

+
+### Relationship Notes
+
+| Relationship | Cardinality | Notes |
+|---|---|---|
+| Club → Member | 1:N | `member.club_id` FK; max enforced by `Club.max_members` |
+| Member → Distribution | 1:N | Each distribution targets one member |
+| Member → MonthlyQuota | 1:N | One row per `(member_id, year, month)` — UNIQUE constraint |
+| Member → User | 1:0..1 | A member may have a portal login; admins may have no `member_id` |
+| Strain → Batch | 1:N | Each batch is one strain; a strain can have many batches |
+| Batch → Distribution | 1:N | A batch can supply many distributions |
+| Batch → StockMovement | 1:N | Every IN/OUT/RECALL against a batch is journaled |
+| Distribution.recorded_by → Member | N:1 | The admin who recorded it (audit trail) |
+
+### Key Constraints
+
+- `Distribution.immutable = true` by default — records are append-only; no UPDATE/DELETE allowed via API
+- `MonthlyQuota` has `UNIQUE(member_id, year, month)` — enforced at DB level
+- `Batch.contamination_flag` triggers recall workflow; `Batch.status = RECALLED` is the final state
+- All `tenant_id` columns: `NOT NULL`, `updatable = false`, set via `@PrePersist`
+- `Member.is_under_21` is derived from `date_of_birth` at registration and re-evaluated on birthday (scheduled job)
+
+---
+
+## 5. API Layer Design
+
+### Base Path: `/api/v1/`
+
+All endpoints are RESTful. JSON request/response bodies. JWT Bearer token required on all except `/auth/**`.
+
+| Controller | Base Path | Key Endpoints |
+|---|---|---|
+| `AuthController` | `/api/v1/auth` | `POST /login`, `POST /refresh`, `POST /logout` |
+| `ClubController` | `/api/v1/clubs` | `GET /`, `POST /`, `GET /{id}`, `PUT /{id}` |
+| `MemberController` | `/api/v1/members` | `GET /`, `POST /`, `GET /{id}`, `PUT /{id}/status`, `GET /me/quota` |
+| `DistributionController` | `/api/v1/distributions` | `POST /`, `GET /?memberId=&month=&year=` |
+| `StockController` | `/api/v1/stock` | `GET /batches`, `POST /batches`, `POST /batches/{id}/recall` |
+| `ReportController` | `/api/v1/reports` | `GET /monthly?month=&year=` (PDF + CSV), `GET /members/{id}/history` |
+| `QuotaController` | `/api/v1/quota` | `GET /members/{id}/current`, `GET /members/{id}/history` |
+
+### Standard HTTP conventions
+- `201 Created` + `Location` header on resource creation
+- `400 Bad Request` with `{ error, message, field? }` on validation failure
+- `403 Forbidden` when role/tenant check fails
+- `422 Unprocessable Entity` when compliance limits are breached (quota exceeded)
+- Pagination: `?page=0&size=20&sort=field,asc`
+
+---
+
+## 6. Compliance Engine
+
+The `ComplianceService` is the heart of regulatory enforcement. It is called synchronously before every distribution is persisted. All operations run in a single `@Transactional` block with optimistic locking to prevent race conditions under concurrent distribution recording.
+
+```java
+@Service
+@Transactional
+public class ComplianceService {
+
+    /**
+     * Validates whether a distribution is legally permitted.
+     *
+     * Checks:
+     *   1. Member is ACTIVE (not SUSPENDED or EXPELLED)
+     *   2. Daily limit: total distributed today + requestedGrams ≤ 25g
+     *   3. Monthly limit: MonthlyQuota.total_distributed + requestedGrams ≤ max_allowed
+     *      where max_allowed = 30g (under-21) or 50g (adult)
+     *   4. Batch is AVAILABLE (not RECALLED or EXHAUSTED)
+     *   5. Batch has sufficient stock
+     *
+     * @throws ComplianceLimitExceededException with remaining quota details
+     * @throws MemberIneligibleException if member is not ACTIVE
+     * @throws BatchUnavailableException if batch is recalled or exhausted
+     */
+    public ComplianceCheckResult checkDistributionAllowed(
+            UUID memberId, UUID batchId, BigDecimal quantityGrams) { ... }
+
+    /**
+     * Returns remaining quota for the current calendar month.
+     * Creates a MonthlyQuota row if none exists (lazy initialization).
+     *
+     * @return QuotaStatus { totalAllowed, totalUsed, remaining, isUnder21 }
+     */
+    public QuotaStatus getMonthlyRemaining(UUID memberId) { ... }
+
+    /**
+     * Flags a batch as RECALLED.
+     * Returns all members who received distributions from this batch
+     * so the caller can trigger notifications.
+     * Writes a StockMovement(RECALL) entry.
+     *
+     * @return List<AffectedMember> { memberId, name, email, totalReceived }
+     */
+    public List<AffectedMember> recallBatch(UUID batchId) { ... }
+}
+```
+
+### Race Condition Prevention
+
+`MonthlyQuota` rows carry a JPA `@Version` column (optimistic locking). If two concurrent requests attempt to increment `total_distributed` simultaneously, one will receive an `OptimisticLockException` and must retry. The retry logic is handled by a `@Retryable` annotation (Spring Retry, max 3 attempts, 50ms backoff).
+
+```java
+@Entity
+public class MonthlyQuota extends AbstractTenantEntity {
+
+    @Version
+    private Long version;  // optimistic lock
+
+    // ... other fields
+}
+```

+
+### Hetzner Sizing
+
+| Resource | Spec | Rationale |
+|---|---|---|
+| Server | CX21 (2 vCPU, 4GB RAM) | Sufficient for < 200 concurrent clubs at MVP |
+| Storage | 40GB SSD (included) | PostgreSQL + logs; Hetzner Volumes for backups |
+| Backups | Hetzner automated backups (20% surcharge) | Daily snapshot retention 7 days |
+| Location | Falkenstein, Germany (FSN1) | DSGVO: data remains within Germany |
+| TLS | Let's Encrypt via Certbot | Auto-renew via cron |
+
+### Deployment Workflow
+
+```
+git push origin main
+  → Gitea webhook fires
+  → deploy.sh on Hetzner:
+      docker pull cannamanage:latest
+      docker compose up -d --no-deps cannamanage-app
+      # zero-downtime: Nginx buffers requests during restart
+```
+
+Flyway migrations run automatically on application startup (`spring.flyway.enabled=true`). Migration files live at `src/main/resources/db/migration/V*.sql`.

+
+## 8. Key Design Decisions
+
+| Decision | Choice | Rationale |
+|---|---|---|
+| Multi-tenancy | Shared schema + `tenant_id` | MVP simplicity; upgrade to schema-per-tenant possible later |
+| Frontend MVP | PrimeFaces JSF | Patrick's existing expertise; fastest path to working UI |
+| Frontend v2 | Next.js / React | Modern UX; deferred to avoid scope creep in MVP |
+| Auth | JWT (stateless) | No sticky sessions needed; horizontal scale ready |
+| PDF generation | iText 7 | Mature Java library; handles complex compliance report layouts |
+| Compliance enforcement | Service layer + DB constraint | Belt-and-suspenders: service validates, DB `UNIQUE` prevents duplicates |
+| Distribution immutability | `immutable = true`, no DELETE API | Audit trail integrity for regulatory compliance |
+| Hosting | Hetzner (Germany) | DSGVO compliance; low cost; German DC |

+## Flow 1: Distribution Recording
+
+Records a cannabis distribution to a member. This is the most compliance-critical path in the system. Every step that can fail returns a user-facing error with actionable detail (remaining quota, batch status, etc.).

+## Flow 2: Member Registration
+
+Registers a new member in the club. Includes DSGVO consent, age validation, under-21 flag assignment, and automatic portal account creation.

+
+## Flow 3: Contamination Batch Recall
+
+Handles the recall of a contaminated batch. This flow is time-critical — speed of notification is essential for member safety. All affected distributions are identified and the prevention officer is notified.
+
+```mermaid

+    START([🟢 Admin selects batch\nand clicks 'Flag Recall']) --> CONFIRM_RECALL{Confirm recall\nof batch?\nThis cannot be undone.}
+
+    CONFIRM_RECALL -->|Cancel| CANCEL([🔴 Cancelled — batch\nstatus unchanged])

+```
+
+---
+
+## Flow 4: Compliance Report Generation
+
+Generates the monthly compliance report required by § 22 KCanG. Covers all distributions within a calendar month, with per-member quota analysis and club metadata for regulatory submission.
+
+```mermaid
+flowchart TD
+    START([🟢 Admin opens\nReports section]) --> SELECT_PERIOD[Admin selects\nmonth and year]

+
+    STORE_FILES --> SUCCESS([✅ Report ready\nOffer download:\n📄 PDF  📊 CSV])
+```
+
+---
+
+## Flow 5: Member Login & Quota Display
+
+The member portal entry flow. Members log in to view their current monthly quota, remaining allowance, and recent distribution history. This is a read-only portal — members cannot modify any data.
+
+```mermaid
+flowchart TD
+    START([🟢 Member navigates\nto member portal URL]) --> SHOW_LOGIN[Show login form:\nemail + password]
+
+    SHOW_LOGIN --> SUBMIT[Member submits credentials]

+    CALL_HISTORY --> DISPLAY_HISTORY["Display last 10 distributions:\n• Date, quantity, strain name\n• Batch code\n• Recorded by (staff name)"]

+
+## Flow Summary
+
+| Flow | Trigger | Key Service | Critical Constraint |
+|---|---|---|---|
+| Distribution Recording | Admin records handout | `ComplianceService` | Daily 25g + monthly 30g/50g limits |
+| Member Registration | Admin adds new member | `MemberService` | Age ≥ 18, DSGVO consent mandatory |
+| Batch Recall | Admin flags contamination | `ComplianceService.recallBatch()` | Immediate prevention officer notification |
+| Report Generation | Admin requests monthly report | `ReportService` | iText 7 PDF + CSV for regulatory filing |
+| Member Login | Member accesses portal | `AuthService` + `QuotaController` | JWT stateless, read-only member view |
+
+### Error Handling Conventions
+
+All flows follow these conventions for user-facing error messages:
+
+- **Compliance errors** (`422 Unprocessable Entity`): Always include remaining quota/allowance so the admin knows what quantity would be valid
+- **Validation errors** (`400 Bad Request`): Include the specific `field` and a human-readable `message` in German (UI locale)
+- **Permission errors** (`403 Forbidden`): Generic message — do not reveal tenant or role details
+- **System errors** (`500 Internal Server Error`): Log full stack trace; show generic user message; alert via email to club admin
+
+### Transaction Boundaries
+
+The Distribution Recording flow (Flow 1) executes steps `SAVE_DIST → UPD_QUOTA → UPD_STOCK → UPD_BATCH` in a **single `@Transactional` block**. If any step fails (e.g., optimistic lock collision on `MonthlyQuota`), the entire transaction rolls back and no partial state is persisted.

+#### Compliance UX — Real-Time Quota Indicator
+
+The quota progress bar updates live as the weight field changes (via `f:ajax event="keyup"`):
+
+| Quota Used After Distribution | Bar Color | Submit Button | Message |
+|---|---|---|---|
+| 0–79% | `#8BC34A` (green) | Enabled | — |
+| 80–99% | `#FF6B35` (orange) | Enabled | "⚠ Approaching monthly limit" |
+| 100% | `#D32F2F` (red) | **Disabled** | "🚫 Monthly limit reached (50g)" |
+| Over-21 member, >30g monthly | `#D32F2F` (red) | **Disabled** | "🚫 Under-21 limit reached (30g)" |
+
+#### Components & Behavior
+
+| Component | PrimeFaces | Behavior |
+|---|---|---|
+| Member search | `p:selectOneMenu` with `p:ajax` filter | Filters on type, shows name + member no. |
+| Strain/Batch dropdown | `p:selectOneMenu` | Populated after member selection; shows only `AVAILABLE` batches |
+| Weight input | `p:inputNumber` min=`0.1` max=`25.0` step=`0.1` | Triggers quota recalculation on blur |
+| Quota bar | `p:progressBar` with dynamic `value` | Color class applied via `styleClass` computed in backing bean |
+| Submit | `p:commandButton` | Disabled via `disabled="#{bean.quotaExceeded}"` |
+| Cancel | `p:link` | Returns to distribution log without saving |

+
+#### Compliance Note — Available Strains Display
+
+Per CanG §§6–7, members may NOT see specific batch quantities or total stock levels. The **Available Strains** table shows only:
+- Strain name
+- Availability status (Available / Limited / Unavailable)
+
+Quantities, batch codes, and THC/CBD percentages are **not exposed** in the member portal.
+
+#### Components & Behavior
+
+| Component | PrimeFaces | Behavior |
+|---|---|---|
+| Quota circle | Custom CSS radial progress (`conic-gradient`) | Computed from monthly total; color matches threshold rules |
+| Quota bar | `p:progressBar` | Same color logic as admin distribution form |
+| History table | `p:dataTable` | Last 10 distributions; sorted newest first; no pagination in MVP |
+| Strains table | `p:dataTable` | `status` column: text + icon only, no quantities |

+└──────────────────────────────────────────┘
+```
+
+#### Design Decisions
+
+- **No self-registration link** — member accounts are created exclusively by admins via the admin portal. The login page has no "Create account" or "Sign up" flow.
+- **No forgot-password link** — password resets are initiated by the club admin only. The login page directs users to contact their admin, avoiding email-based reset flows that would require verified email infrastructure in MVP.
+- **No social login** — DSGVO compliance and club accountability require traceable credential management.
+- **Form submission:** POST to `/login` (Spring Security form login), redirect to `/member/dashboard` on success.
+
+#### Components & Behavior
+
+| Component | PrimeFaces | Behavior |
+|---|---|---|
+| Email field | `p:inputText` with `required="true"` | Bean Validation `@Email` |
+| Password field | `p:password` feedback=`false` | No strength meter on login |
+| Login button | `p:commandButton` | Submit form; shows `p:messages` on failure |
+| Error message | `p:messages` | "Invalid email or password." (never specific about which field failed) |

+
+## 5. Responsive Design Notes
+
+### MVP (v1) — Desktop-First
+
+Target viewport: **1024px+**. PrimeFaces responsive grid (`p:panelGrid` with responsive columns, `ui-g-12 ui-md-6 ui-lg-4`) handles most layout adaptation down to tablet without custom media queries.
+
+| Breakpoint | Behavior |
+|---|---|
+| `≥ 1280px` | Full layout — sidebar + content side-by-side |
+| `1024–1279px` | Sidebar collapses to icon-only (60px); tooltips on hover |
+| `768–1023px` | Sidebar hidden; hamburger menu in top navbar |
+| `< 768px` | Admin portal degraded (tables scroll horizontally) |
+
+### Member Portal — Mobile-First from Day One
+
+Members will typically check quota status on their phone. The member portal is designed mobile-first regardless of MVP/v2 timeline.
+
+| Breakpoint | Behavior |
+|---|---|
+| `≥ 1024px` | Two-column layout: quota circle left, history right |
+| `768–1023px` | Single-column, full-width cards |
+| `375–767px` | Single-column, compact quota ring, condensed table |
+| `< 375px` | Minimum supported; no horizontal scroll |
+
+### v2 Roadmap
+
+- PWA manifest + service worker (offline quota display)
+- 768px and 375px explicit breakpoints with design tokens
+- Touch-friendly `p:sidebar` for mobile member nav
+- Push notifications for low quota warnings
+
+---
+
+## 6. Accessibility
+
+CannaManage targets **WCAG 2.1 AA** compliance across both portals.
+
+### Keyboard Navigation
+
+| Element | Keyboard Behavior |
+|---|---|
+| Navigation sidebar | Tab navigates items; Enter activates |
+| Data tables | Tab to table; arrow keys for row navigation |
+| Dropdown menus | Enter/Space to open; arrow keys to navigate; Escape to close |
+| Modal dialogs | Focus trapped inside; Escape to close; first focusable element receives focus on open |
+| Confirmation dialogs | Tab between Confirm and Cancel; Enter on focused button |
+
+### Screen Reader Support
+
+- All `p:inputText` / `p:inputNumber` fields have `<label>` with `for` attribute
+- `aria-label` set on icon-only buttons (e.g., recall action column)
+- `aria-live="polite"` region on quota bar — announces percentage changes
+- `aria-describedby` links compliance warning messages to the weight input
+- PrimeFaces generates `role="grid"` and `aria-rowcount` on all data tables
+
+### Color Independence
+
+Status badges must never rely on color alone:
+
+| Status | Color | Icon | Text label |
+|---|---|---|---|
+| AVAILABLE | Green | ✓ | "Available" |
+| LOW | Orange | ⚠ | "Low Stock" |
+| RECALLED | Red | ⛔ | "Recalled" |
+| EXHAUSTED | Gray | — | "Exhausted" |
+
+Quota progress bar additionally shows numeric percentage text alongside color change.
+
+### Contrast Ratios
+
+| Foreground | Background | Ratio | AA pass |
+|---|---|---|---|
+| `#FFFFFF` | `#2D5016` | 9.1:1 | ✅ |
+| `#1A1A1A` | `#F5F5F5` | 16.0:1 | ✅ |
+| `#1A1A1A` | `#FFFFFF` | 19.0:1 | ✅ |
+| `#FFFFFF` | `#D32F2F` | 5.1:1 | ✅ |
+| `#FFFFFF` | `#FF6B35` | 3.1:1 | ⚠ verify at large text only |

+`cannamanage-api` and `cannamanage-web` are siblings — they do not depend on each other. The web module is the PrimeFaces JSF frontend (MVP); the API module provides the REST layer (future mobile / integration use).

+Java 21. All modern language features are permitted and preferred:
+
+| Feature | Use Case | Example |
+|---|---|---|
+| Records | DTOs, value objects, query results | `record MemberSummary(UUID id, String name, BigDecimal quotaUsed)` |
+| Sealed classes | Result types, compliance outcomes | `sealed interface QuotaResult permits QuotaOk, QuotaWarning, QuotaExceeded` |
+| Text blocks | JPQL, SQL in tests, JSON fixtures | `String jpql = """ SELECT m FROM Member m WHERE... """` |
+| Pattern matching `instanceof` | Type checks in services | `if (result instanceof QuotaExceeded e) { ... }` |
+| Switch expressions | Status mapping, report routing | `yield` syntax preferred |
+
+### Package Structure
+
+Pattern: `de.cannamanage.[module].[layer]`
+
+```
+de.cannamanage.domain.member          # Member entity
+de.cannamanage.domain.compliance      # ComplianceConstants, exceptions
+de.cannamanage.service.distribution   # DistributionService
+de.cannamanage.api.stock              # StockController, BatchDto
+de.cannamanage.web.admin              # DistributionFormBean
+de.cannamanage.report.monthly         # MonthlyComplianceReport
+```
+
+### Class Naming Conventions
+
+| Type | Pattern | Example |
+|---|---|---|
+| JPA Entity | `{Domain}` | `Member`, `Distribution`, `Batch` |
+| Spring Service | `{Domain}Service` | `MemberService`, `ComplianceService` |
+| Repository | `{Domain}Repository` | `DistributionRepository` |
+| REST Controller | `{Domain}Controller` | `StockController` |
+| JSF Backing Bean | `{Screen}Bean` | `DistributionFormBean`, `AdminDashboardBean` |
+| DTO (request) | `{Domain}Request` | `CreateDistributionRequest` |
+| DTO (response) | `{Domain}Response` / `{Domain}Dto` | `MemberSummaryDto` |
+| Exception | `{Condition}Exception` | `QuotaExceededException`, `BatchRecalledException` |
+| Enum | `{Domain}Status` / `{Domain}Type` | `BatchStatus`, `MembershipType` |
+| Constants class | `{Domain}Constants` | `ComplianceConstants` |
+
+### Dependency Injection
+
+**Constructor injection only.** Field injection (`@Autowired` on fields) is prohibited.
+
+```java
+// ✅ Correct
+@Service
+@RequiredArgsConstructor
+public class DistributionService {
+
+    private final DistributionRepository distributionRepository;
+    private final ComplianceService complianceService;
+    private final MemberRepository memberRepository;
+}
+
+// ❌ Prohibited
+@Service
+public class DistributionService {
+
+    @Autowired
+    private DistributionRepository distributionRepository;
+}
+```
+
+Lombok `@RequiredArgsConstructor` is the preferred way to generate the constructor.
+
+### Entity Base Class
+
+All `@Entity` classes must extend `AbstractTenantEntity`. No raw entities without tenant isolation.
+
+```java
+// de.cannamanage.domain.common.AbstractTenantEntity
+@MappedSuperclass
+@EntityListeners(AuditingEntityListener.class)
+public abstract class AbstractTenantEntity {
+
+    @Id
+    @GeneratedValue(strategy = GenerationType.UUID)
+    private UUID id;
+
+    @Column(name = "tenant_id", nullable = false, updatable = false)
+    private UUID tenantId;
+
+    @CreatedDate
+    @Column(name = "created_at", nullable = false, updatable = false)
+    private Instant createdAt;
+
+    @LastModifiedDate
+    @Column(name = "updated_at", nullable = false)
+    private Instant updatedAt;
+}
+
+// ✅ All entities extend this
+@Entity
+@Table(name = "members")
+@Getter
+@Builder
+@NoArgsConstructor
+@AllArgsConstructor
+public class Member extends AbstractTenantEntity {
+    // domain fields only — no id/tenantId/audit fields here
+}
+```
+
+### Transaction Boundaries
+
+- `@Transactional` belongs on **service layer** methods only
+- Controllers and repositories must not declare `@Transactional`
+- Use `@Transactional(readOnly = true)` for query-only methods — improves performance with Hibernate's read-only session optimization
+
+```java
+// ✅ Service layer — correct
+@Service
+@RequiredArgsConstructor
+public class MemberService {
+
+    @Transactional(readOnly = true)
+    public MemberSummaryDto getById(UUID memberId, UUID tenantId) { ... }
+
+    @Transactional
+    public void updateMemberStatus(UUID memberId, MemberStatus status, UUID tenantId) { ... }
+}
+
+// ❌ Controller — prohibited
+@RestController
+public class MemberController {
+
+    @Transactional  // Never here
+    @GetMapping("/members/{id}")
+    public MemberSummaryDto getMember(@PathVariable UUID id) { ... }
+}
+```
+
+### Lombok Usage
+
+| Annotation | Allowed | Notes |
+|---|---|---|
+| `@Getter` | ✅ | On entities and DTOs |
+| `@Setter` | ✅ | Use sparingly on entities; prefer builder pattern |
+| `@Builder` | ✅ | On entities and DTOs |
+| `@RequiredArgsConstructor` | ✅ | Services, beans (for DI) |
+| `@NoArgsConstructor` | ✅ | JPA requires no-arg constructor |
+| `@AllArgsConstructor` | ✅ | With `@Builder` |
+| `@ToString` | ✅ | Exclude sensitive fields: `@ToString.Exclude` on `passwordHash` etc. |
+| `@EqualsAndHashCode` | ✅ | Entities: only on `id` field |
+| `@Data` | ❌ | **Prohibited on entities** — generates mutable setters for all fields, breaks JPA proxy patterns |
+| `@SneakyThrows` | ❌ | Never hide checked exceptions |
+
+### Code Style
+
+- **Checkstyle config:** Google Java Style Guide (`checkstyle-google.xml` in parent POM)
+- **Indentation:** 4 spaces (no tabs)
+- **Line length:** 120 characters max
+- **No magic numbers** — use named constants or enums:
+
+```java
+// ❌ Magic number
+if (member.getAge() < 21) { limit = 30; }
+
+// ✅ Named constant
+if (member.getAge() < ComplianceConstants.AGE_LIMIT_UNDER21) {
+    limit = ComplianceConstants.MONTHLY_LIMIT_UNDER21_GRAMS;
+}
+```
+
+---
+
+## 3. Compliance Code Rules
+
+These rules apply exclusively to code that enforces CanG (Cannabisgesetz) distribution limits. Violations here carry legal risk.
+
+### Compliance Constants
+
+All legal limits live in a single, centrally tested constants class. **Never hardcode these values inline.**
+
+```java
+// de.cannamanage.domain.compliance.ComplianceConstants
+public final class ComplianceConstants {
+
+    private ComplianceConstants() {} // no instantiation
+
+    /** Maximum grams per single distribution for any member. */
+    public static final BigDecimal DAILY_LIMIT_GRAMS = new BigDecimal("25.0");
+
+    /** Monthly gram limit for adult members (age ≥ 21). */
+    public static final BigDecimal MONTHLY_LIMIT_ADULT_GRAMS = new BigDecimal("50.0");
+
+    /** Monthly gram limit for members under 21 years of age (CanG §10 Abs.1). */
+    public static final BigDecimal MONTHLY_LIMIT_UNDER21_GRAMS = new BigDecimal("30.0");
+
+    /** Age threshold below which the reduced monthly limit applies. */
+    public static final int AGE_LIMIT_UNDER21 = 21;
+
+    /** Minimum age for club membership (CanG §15 Abs.1). */
+    public static final int MINIMUM_MEMBER_AGE = 18;
+}
+```
+
+### ComplianceService Rules
+
+1. `ComplianceService` methods **must always execute within a `@Transactional` boundary** — either by being called from a service method already in a transaction, or by declaring `@Transactional` themselves. The compliance check and the distribution record creation must be atomic.
+
+2. Every public method in `ComplianceService` must have a corresponding test in `ComplianceServiceTest` that exercises its boundary conditions.
+
+3. `ComplianceService` is the **only** class permitted to read `ComplianceConstants` limits and make pass/fail decisions. No other class performs limit arithmetic.
+
+```java
+@Service
+@RequiredArgsConstructor
+public class ComplianceService {
+
+    private final DistributionRepository distributionRepository;
+
+    /**
+     * Validates whether a distribution of the given weight is permitted for the member.
+     *
+     * <p>Checks the daily single-distribution limit and the member's monthly quota.
+     * Must be called inside an existing @Transactional boundary — the calling
+     * DistributionService is responsible for the transaction.
+     *
+     * @param memberId   the member receiving the distribution
+     * @param tenantId   the club's tenant identifier
+     * @param weightGrams the proposed distribution weight in grams
+     * @return QuotaOk if permitted; QuotaWarning if >80% used; QuotaExceeded if over limit
+     * @throws IllegalArgumentException if weightGrams exceeds DAILY_LIMIT_GRAMS
+     */
+    public QuotaResult checkDistributionAllowed(UUID memberId, UUID tenantId, BigDecimal weightGrams) {
+        if (weightGrams.compareTo(ComplianceConstants.DAILY_LIMIT_GRAMS) > 0) {
+            throw new IllegalArgumentException(
+                "Single distribution exceeds daily limit of " + ComplianceConstants.DAILY_LIMIT_GRAMS + "g");
+        }
+        // ... monthly quota logic using ComplianceConstants
+    }
+}
+```
+
+### Distribution Record Immutability
+
+Once written, a `Distribution` record may never be modified (legal audit trail requirement). Enforce this at the JPA level:
+
+```java
+@Entity
+@Table(name = "distributions")
+@Getter
+@Builder
+@NoArgsConstructor
+@AllArgsConstructor
+public class Distribution extends AbstractTenantEntity {
+
+    @Column(name = "member_id", nullable = false, updatable = false)
+    private UUID memberId;
+
+    @Column(name = "batch_id", nullable = false, updatable = false)
+    private UUID batchId;
+
+    @Column(name = "weight_grams", nullable = false, updatable = false,
+            precision = 8, scale = 2)
+    private BigDecimal weightGrams;
+
+    @Column(name = "distributed_at", nullable = false, updatable = false)
+    private Instant distributedAt;
+
+    @Column(name = "recorded_by_admin_id", nullable = false, updatable = false)
+    private UUID recordedByAdminId;
+
+    // No setters — @Getter only, no @Setter
+    // updatable = false on ALL columns — Hibernate will reject any UPDATE attempt
+}
+```
+
+### Compliance Test Coverage Requirement
+
+`ComplianceServiceTest` must include at minimum:
+
+| Test Method | What It Covers |
+|---|---|
+| `checkDistributionAllowed_givenWeightAt25g_shouldReturnQuotaOk` | Exactly at daily limit |
+| `checkDistributionAllowed_givenWeightOver25g_shouldThrowIllegalArgument` | Daily limit exceeded |
+| `checkDistributionAllowed_givenMemberAtMonthlyLimit_shouldReturnQuotaExceeded` | Adult at 50g |
+| `checkDistributionAllowed_givenUnder21MemberAt30g_shouldReturnQuotaExceeded` | Under-21 at 30g |
+| `checkDistributionAllowed_givenUnder21MemberAtAdultLimit_shouldReturnQuotaExceeded` | Under-21 must not reach 50g |
+| `checkDistributionAllowed_givenMemberAt80Percent_shouldReturnQuotaWarning` | Warning threshold |
+| `checkDistributionAllowed_givenMemberAt40g_shouldReturnQuotaOk` | Normal adult, within limit |
+

+
+fix(member): correct under-21 flag when age is exactly 21
+
+Age comparison was using < instead of <=. Members who turn 21 on the
+exact distribution date now correctly receive the adult (50g) limit.
+Closes #17
+
+test(distribution): add quota boundary tests for 30g under-21 limit
+
+Adds 6 parameterized test cases covering 28g, 29g, 29.9g, 30g, 30.1g,
+and 31g for under-21 members. All reference ComplianceConstants — no
+hardcoded values in test assertions.

+methodName_givenCondition_shouldExpectedBehavior
+```
+
+```java
+// ✅ Correct

+
+@Test
+void getQuotaRemaining_givenUnder21Member_shouldCapAt30g()
+
+@Test
+void generateMonthlyReport_givenNoPriorDistributions_shouldReturnZeroTotals()
+```
+
+### Unit Test Structure
+
+```java
+@ExtendWith(MockitoExtension.class)
+class ComplianceServiceTest {
+
+    @Mock
+    private DistributionRepository distributionRepository;
+
+    @InjectMocks
+    private ComplianceService complianceService;
+
+    @Test
+    void checkDistributionAllowed_givenMemberAtMonthlyLimit_shouldReturnQuotaExceeded() {
+        // GIVEN
+        UUID memberId = UUID.randomUUID();
+        UUID tenantId = UUID.randomUUID();
+        BigDecimal currentMonthTotal = ComplianceConstants.MONTHLY_LIMIT_ADULT_GRAMS;
+
+        when(distributionRepository.sumWeightByMemberAndMonth(eq(memberId), eq(tenantId), any()))
+            .thenReturn(currentMonthTotal);
+
+        // WHEN
+        QuotaResult result = complianceService.checkDistributionAllowed(
+            memberId, tenantId, new BigDecimal("1.0"));
+
+        // THEN
+        assertThat(result).isInstanceOf(QuotaExceeded.class);
+    }
+}
+```
+
+### Integration Test Structure
+
+```java
+@SpringBootTest
+@Testcontainers
+@Transactional  // rolls back after each test
+class DistributionServiceIntegrationTest {
+
+    @Container
+    static PostgreSQLContainer<?> postgres = new PostgreSQLContainer<>("postgres:16-alpine");
+
+    @DynamicPropertySource
+    static void configureDataSource(DynamicPropertyRegistry registry) {
+        registry.add("spring.datasource.url", postgres::getJdbcUrl);
+        registry.add("spring.datasource.username", postgres::getUsername);
+        registry.add("spring.datasource.password", postgres::getPassword);
+    }
+
+    // Tests run against real PostgreSQL — Flyway migrations apply automatically
+}
+```
+
+### Coverage Target
+
+| Module | Line Coverage Target |
+|---|---|
+| `cannamanage-service` | **≥ 80%** (enforced by JaCoCo in CI) |
+| `cannamanage-domain` | ≥ 70% (entities + value objects) |
+| `cannamanage-api` | ≥ 70% (controllers via MockMvc) |
+| `cannamanage-report` | ≥ 60% (PDF generation harder to test) |
+| `cannamanage-web` | Best effort (JSF backing beans — limited testability) |
+
+### Test Rules
+
+1. **No test may hardcode a compliance limit value.** All assertions must reference `ComplianceConstants`:
+
+```java
+// ❌ Prohibited
+assertThat(limit).isEqualTo(new BigDecimal("50.0"));
+
+// ✅ Required
+assertThat(limit).isEqualTo(ComplianceConstants.MONTHLY_LIMIT_ADULT_GRAMS);
+```
+
+2. Parameterized tests (`@ParameterizedTest`) are strongly preferred for boundary condition coverage.
+
+3. Test data builders (or fixtures) must live in `src/test/java/.../fixtures/` — no anonymous object creation scattered across test methods.
+
+---
+
+## 6. Code Review Checklist
+
+Since CannaManage is a solo development project, a self-review checklist replaces a peer review process. All items must be checked before merging any PR to `main`.
+
+### Self-Review Checklist
+
+```markdown
+## Compliance & Legal
+- [ ] All distribution limits reference `ComplianceConstants` — zero hardcoded values
+- [ ] `Distribution` entity fields are annotated `@Column(updatable = false)` where required
+- [ ] `ComplianceService` calls are only made inside `@Transactional` boundaries
+- [ ] New compliance rules have corresponding unit tests in `ComplianceServiceTest`
+
+## Data & Multi-Tenancy
+- [ ] New entity extends `AbstractTenantEntity`
+- [ ] `tenant_id` is never accepted from user input (HTTP body, query param, path variable)
+- [ ] All repository queries filter by `tenantId` — no cross-tenant data leakage possible
+
+## Security & DSGVO
+- [ ] No PII in log statements (no email, full name, member number in log lines)
+- [ ] No passwords, tokens, or secrets hardcoded anywhere
+- [ ] New REST endpoints annotated with `@PreAuthorize`
+- [ ] DTOs validated with Bean Validation annotations (`@NotNull`, `@Size`, etc.)
+
+## Database

+- [ ] Migration file is backward-compatible or includes rollback notes
+- [ ] No `@Column(nullable = false)` added without corresponding DB migration
+
+## Code Quality
+- [ ] Constructor injection used — no `@Autowired` field injection
+- [ ] No `@Data` on JPA entities
+- [ ] No magic numbers — named constants or enums used

+- [ ] Javadoc on all public service methods
+
+## Testing
+- [ ] Unit test added for new service method
+- [ ] Integration test updated if schema or contract changed

+- [ ] Test method names follow `method_givenCondition_shouldExpect` pattern
+
+## General
+- [ ] Commit message follows Conventional Commits format
+- [ ] Branch name follows `feature/US-XXX-` or `fix/` convention
+- [ ] No `TODO` comments left in production code (use GitHub Issues instead)
+```

+
+## 7. Security Standards
+
+### Authentication & Authorization
+
+```java
+// JWT secret from environment only — never in application.properties
+@Value("${JWT_SECRET}")
+private String jwtSecret;
+
+// All endpoints behind @PreAuthorize — no security by obscurity
+@RestController
+@RequestMapping("/api/v1/distributions")
+public class DistributionController {
+
+    @GetMapping
+    @PreAuthorize("hasRole('ADMIN')")
+    public Page<DistributionDto> list(...) { ... }
+
+    @PostMapping
+    @PreAuthorize("hasRole('ADMIN')")
+    public DistributionDto create(...) { ... }
+}
+
+// Member portal endpoints restricted to role + own data
+@GetMapping("/api/v1/member/quota")
+@PreAuthorize("hasRole('MEMBER') and #memberId == authentication.principal.memberId")
+public QuotaDto getQuota(@RequestParam UUID memberId) { ... }
+```
+
+### CORS Configuration
+
+```java
+@Bean
+CorsConfigurationSource corsConfigurationSource() {
+    CorsConfiguration config = new CorsConfiguration();
+    // No wildcard — club subdomain only
+    config.setAllowedOriginPatterns(List.of("https://*.cannamanage.de"));
+    config.setAllowedMethods(List.of("GET", "POST", "PUT", "DELETE", "OPTIONS"));
+    config.setAllowedHeaders(List.of("Authorization", "Content-Type"));
+    config.setAllowCredentials(true);
+    // ...
+}
+```
+
+### Input Validation
+
+All DTOs must be annotated with Bean Validation constraints. The controller calls `@Valid` on request bodies.
+
+```java
+public record CreateDistributionRequest(
+
+    @NotNull(message = "Member ID is required")
+    UUID memberId,
+
+    @NotNull(message = "Batch ID is required")
+    UUID batchId,
+
+    @NotNull(message = "Weight is required")
+    @DecimalMin(value = "0.1", message = "Weight must be at least 0.1g")
+    @DecimalMax(value = "25.0", message = "Weight cannot exceed daily limit")
+    BigDecimal weightGrams
+) {}
+```
+
+### SQL Injection Prevention
+
+- **JPA named queries only** — no string concatenation in JPQL
+- Spring Data JPA repository methods generate parameterized queries automatically
+- Native SQL queries use `@Query` with named parameters (`:param` syntax), never `+`
+
+```java
+// ✅ Safe — parameterized
+@Query("SELECT SUM(d.weightGrams) FROM Distribution d WHERE d.memberId = :memberId AND d.tenantId = :tenantId AND MONTH(d.distributedAt) = :month")
+BigDecimal sumWeightByMemberAndMonth(@Param("memberId") UUID memberId,
+                                     @Param("tenantId") UUID tenantId,
+                                     @Param("month") int month);
+
+// ❌ Prohibited — SQL injection risk
+String jpql = "SELECT ... WHERE name = '" + memberName + "'";
+```
+
+### Password Hashing
+
+```java
+@Bean
+PasswordEncoder passwordEncoder() {
+    return new BCryptPasswordEncoder(12);  // strength 12 — ~250ms per hash on modern hardware
+}
+```
+
+### Sensitive Data Logging
+
+```java
+// ❌ Never log PII
+log.info("Processing distribution for member: {}", member.getEmail());
+log.info("Member {} requested quota", member.getFullName());
+
+// ✅ Log with opaque identifiers only
+log.info("Processing distribution for memberId={} tenantId={}", member.getId(), tenantId);
+log.info("Quota check passed for memberId={}", memberId);
+```

+### Profile Strategy
+
+> **`spring.profiles.active=prod` is NOT a security mechanism.** Never use profile-based condition checks to gate security-relevant behavior (e.g., `@ConditionalOnProperty(name="spring.profiles.active", havingValue="prod")`).
+
+Profiles are used **only** for infrastructure wiring (in-memory H2 vs. real PostgreSQL for tests, Testcontainers vs. external DB).
+
+| Profile | Usage |
+|---|---|
+| `(none)` | Production — all config from environment variables |
+| `test` | JUnit integration tests — Testcontainers PostgreSQL |
+| `dev` | Local development — Docker Compose PostgreSQL, verbose SQL logging |
+
+### Local Development Setup
+
+```bash
+# Start local PostgreSQL via Docker Compose
+docker compose up -d postgres
+
+# Run with dev profile (verbose SQL, local DB)
+./mvnw spring-boot:run -Dspring-boot.run.profiles=dev \
+  -Dspring-boot.run.arguments="--DB_URL=jdbc:postgresql://localhost:5432/cannamanage_dev \
+    --DB_USERNAME=cannamanage --DB_PASSWORD=dev_password \
+    --JWT_SECRET=$(openssl rand -base64 32)"

+# 08 — Test Plan
+
+**Project:** CannaManage — B2B SaaS for German Cannabis Social Clubs  
+**Version:** 0.1.0-PLAN  
+**Date:** 2026-04-06  
+**Status:** Draft
+
+---
+
+## 1. Test Strategy Overview
+
+### 1.1 Testing Pyramid
+
+```
+        ┌─────────────────┐
+        │   E2E Tests     │  10% — Playwright (deferred to v2)
+        │   (10%)         │
+        ├─────────────────┤
+        │ Integration     │  20% — Spring Boot Test + Testcontainers
+        │   Tests (20%)   │
+        ├─────────────────┤
+        │   Unit Tests    │  70% — JUnit 5 + Mockito
+        │   (70%)         │
+        └─────────────────┘
+```
+
+The compliance-critical path (`ComplianceService`) requires **100% line coverage** — no exceptions. Every quota rule is a legal obligation under CanG §§19–22.
+
+### 1.2 Tools and Frameworks
+
+| Layer | Tool | Purpose |
+|-------|------|---------|
+| Unit | JUnit 5 (`junit-jupiter`) | Test runner |
+| Unit | Mockito 5 | Mock dependencies |
+| Unit | AssertJ | Fluent assertions |
+| Integration | Spring Boot Test (`@SpringBootTest`) | Full application context |
+| Integration | Testcontainers (PostgreSQL module) | Real DB in Docker |
+| Integration | MockMvc / RestAssured | HTTP layer testing |
+| Coverage | JaCoCo | Line/branch coverage reporting |
+| E2E | Playwright (Java) | Browser automation — **deferred to v2** |
+
+### 1.3 CI Trigger Policy
+
+| Branch pattern | Tests run |
+|---------------|-----------|
+| `feature/*` | Unit tests only (`./mvnw test`) |
+| `develop` | Unit + Integration (`./mvnw verify -P integration-tests`) |
+| `main` | Unit + Integration + coverage gate |
+
+Coverage gate blocks merge to `main` if `ComplianceService` drops below 100%.

+
+## 2. Unit Test Cases — ComplianceService
+
+**Class under test:** `de.cannamanage.service.ComplianceService`

+
+---
+
+**TC-002** | `checkDistributionAllowed_givenUnder21AtMonthlyLimit_shouldThrowQuotaExceededMonthly`
+- **Given:** Under-21 member (age 18) with exactly 30.0g distributed this calendar month, requesting 1.0g more

+- **Compliance ref:** CanG §19(3) — 30g/month limit for under-21 members
+
+---
+
+**TC-003** | `checkDistributionAllowed_givenAdultAtDailyLimit_shouldThrowQuotaExceededDaily`
+- **Given:** Adult member with exactly 25.0g distributed today, requesting 0.5g more
+- **When:** `complianceService.checkDistributionAllowed(memberId, 0.5)`

+---
+
+**TC-004** | `checkDistributionAllowed_givenUnder21RequestingHighThcStrain_shouldThrowHighThcRestricted`
+- **Given:** Under-21 member (age 20), requesting a strain with THC content 12.5% (exceeds 10% threshold)
+- **When:** `complianceService.checkDistributionAllowed(memberId, 5.0, strainId)`
+- **Then:** Throws `QuotaExceededException` with code `HIGH_THC_RESTRICTED_UNDER_21`
+- **Compliance ref:** CanG §19(4) — under-21 members restricted to ≤10% THC strains
+
+---
+
+**TC-005** | `checkDistributionAllowed_givenAdultAt49gMonthlyRequesting2g_shouldThrowQuotaExceededMonthly`
+- **Given:** Adult member with 49.0g distributed this month, requesting 2.0g (would total 51.0g)
+- **When:** `complianceService.checkDistributionAllowed(memberId, 2.0)`
+- **Then:** Throws `QuotaExceededException` with code `QUOTA_EXCEEDED_MONTHLY`
+- **Note:** Even partial over-quota requests must be rejected in full; no partial fulfillment
+
+---
+
+**TC-006** | `checkDistributionAllowed_givenAdultAt0gRequesting25g_shouldReturnAllowed`
+- **Given:** Adult member with 0.0g distributed this month and today, requesting 25.0g
+- **When:** `complianceService.checkDistributionAllowed(memberId, 25.0)`
+- **Then:** Returns `DistributionAllowedResult` with `allowed = true`, `remainingDaily = 0.0`, `remainingMonthly = 25.0`
+- **Note:** Exactly at daily limit — allowed
+
+---
+
+**TC-007** | `checkDistributionAllowed_givenAdultAt24_9gDailyRequesting0_1g_shouldReturnAllowed`
+- **Given:** Adult member with 24.9g distributed today, requesting 0.1g (would reach exactly 25.0g)
+- **When:** `complianceService.checkDistributionAllowed(memberId, 0.1)`
+- **Then:** Returns `allowed = true`, `remainingDaily = 0.0`
+- **Note:** Boundary — exactly at limit is allowed
+
+---
+
+**TC-008** | `checkDistributionAllowed_givenAdultAt24_9gDailyRequesting0_2g_shouldThrowQuotaExceededDaily`
+- **Given:** Adult member with 24.9g distributed today, requesting 0.2g (would total 25.1g)
+- **When:** `complianceService.checkDistributionAllowed(memberId, 0.2)`
+- **Then:** Throws `QuotaExceededException` with code `QUOTA_EXCEEDED_DAILY`

+
+---
+
+**TC-009** | `checkDistributionAllowed_givenSuspendedMember_shouldThrowMemberInactive`

+
+---
+
+**TC-010** | `checkDistributionAllowed_givenExpelledMember_shouldThrowMemberInactive`
+- **Given:** Member with `status = MemberStatus.EXPELLED`, requesting any amount
+- **When:** `complianceService.checkDistributionAllowed(memberId, 5.0)`
+- **Then:** Throws `QuotaExceededException` with code `MEMBER_INACTIVE`
+- **Note:** Expelled members are permanently blocked, no quota check performed
+
+---
+
+## 3. Unit Test Cases — MemberService
+
+**Class under test:** `de.cannamanage.service.MemberService`  
+**Dependencies mocked:** `MemberRepository`, `ClubRepository`, `PasswordEncoder`
+
+---
+
+**TC-011** | `createMember_givenAge17_shouldThrowUnderageException`
+- **Given:** `CreateMemberRequest` with DOB resulting in age 17 at time of registration
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Throws `UnderageException` with message containing minimum age (18)
+- **Compliance ref:** CanG §6(1) — membership requires minimum age 18
+
+---
+
+**TC-012** | ~~`createMember_givenAge18_shouldSucceedAndSetIsUnder21False`~~ — *this case is incorrect*
+
+> **Note:** Age 18 IS under 21, therefore `isUnder21 = true`. See TC-013.
+
+---
+
+**TC-013** | `createMember_givenAge18_shouldSucceedAndSetIsUnder21True`
+- **Given:** `CreateMemberRequest` with DOB resulting in age 18 at time of registration
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Returns created `Member` with `isUnder21 = true`, `status = ACTIVE`
+- **Note:** The 18-year-old flag matters for quota enforcement (30g/month, ≤10% THC)
+
+---
+
+**TC-014** | `createMember_givenAge21_shouldSucceedAndSetIsUnder21False`
+- **Given:** `CreateMemberRequest` with DOB resulting in age exactly 21 at time of registration
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Returns created `Member` with `isUnder21 = false`, `status = ACTIVE`
+- **Note:** Age 21 is the boundary — exactly 21 qualifies as adult for quota purposes
+
+---
+
+**TC-015** | `createMember_givenDuplicateEmail_shouldThrowDuplicateMemberException`
+- **Given:** `MemberRepository.existsByEmailAndTenantId(email, tenantId)` returns `true`
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Throws `DuplicateMemberException` with code `DUPLICATE_EMAIL`
+- **Note:** Email uniqueness is per-tenant, not global
+
+---
+
+## 4. Unit Test Cases — Tenant Isolation
+
+**Class under test:** JPA repositories with `@TenantAware` filter active  
+**Setup:** Thread-local `TenantContext` populated via `TenantContextHolder.setTenantId()`
+
+---
+
+**TC-016** | `distributionRepository_givenTenantAContext_shouldNotReturnTenantBData`
+- **Given:** Two tenants (Tenant A: UUID-A, Tenant B: UUID-B); 5 distributions for each; `TenantContextHolder` set to UUID-A
+- **When:** `distributionRepository.findAll()`
+- **Then:** Returns exactly 5 records, all with `tenantId = UUID-A`; zero records from Tenant B
+- **Note:** Hibernate filter `tenantFilter` must be enabled in `TenantAwareInterceptor`
+
+---
+
+**TC-017** | `memberRepository_givenTenantAContext_shouldNotSeeClubBMembers`
+- **Given:** 10 members in Club A, 8 members in Club B; context set to Club A's tenant
+- **When:** `memberRepository.findAll()`
+- **Then:** Returns exactly 10 records; no member from Club B present
+- **Note:** Cross-tenant data leakage is a GDPR violation, not just a business bug
+
+---
+
+## 5. Integration Test Cases (Testcontainers)
+
+**Setup:** `@SpringBootTest(webEnvironment = RANDOM_PORT)` with `@Testcontainers`; real PostgreSQL 16 container; Flyway migrations applied before each test class.
+
+---
+
+**TC-018** | `POST /api/v1/distributions — successful distribution recording`
+- **Given:** Active adult member with 0g distributed; valid `DistributionRequest` for 10.0g; authenticated as `ROLE_ADMIN`
+- **When:** `POST /api/v1/distributions` with valid JWT
+- **Then:** HTTP 201; response body contains `distributionId`, `amount = 10.0`, `recordedAt`; DB contains one `distribution` row with `is_recalled = false`
+
+---
+
+**TC-019** | `POST /api/v1/distributions — quota exceeded returns 422`
+- **Given:** Adult member with 50.0g already distributed this month; requesting 1.0g more
+- **When:** `POST /api/v1/distributions`
+- **Then:** HTTP 422; response body `{"errorCode": "QUOTA_EXCEEDED_MONTHLY", "remainingMonthly": 0.0}`
+
+---
+
+**TC-020** | `POST /api/v1/distributions — concurrent race condition (last gram)`
+- **Given:** Adult member with 24.9g distributed today; two concurrent requests each for 0.2g (both would individually exceed 25g/day)
+- **When:** Both requests fired simultaneously via two threads
+- **Then:** Exactly one succeeds (HTTP 201); exactly one fails (HTTP 422 `QUOTA_EXCEEDED_DAILY`); DB total does not exceed 25.0g
+- **Mechanism:** `SELECT ... FOR UPDATE` on quota aggregation query prevents double-spend
+
+---
+
+**TC-021** | `POST /api/v1/auth/login — valid credentials return JWT`
+- **Given:** Admin user with email `admin@test-club.de`, correct password
+- **When:** `POST /api/v1/auth/login` with `{"email": "admin@test-club.de", "password": "..."}`
+- **Then:** HTTP 200; response contains `accessToken` (JWT), `tokenType = "Bearer"`, `expiresIn = 3600`
+
+---
+
+**TC-022** | `POST /api/v1/auth/login — invalid credentials return 401`
+- **Given:** Admin user exists; wrong password provided
+- **When:** `POST /api/v1/auth/login` with wrong password
+- **Then:** HTTP 401; response `{"errorCode": "INVALID_CREDENTIALS"}`; no token issued
+
+---
+
+**TC-023** | `GET /api/v1/members — ROLE_MEMBER accessing admin endpoint returns 403`
+- **Given:** Authenticated user with `ROLE_MEMBER` JWT (not ROLE_ADMIN)
+- **When:** `GET /api/v1/members` (admin-only endpoint)
+- **Then:** HTTP 403; response `{"errorCode": "FORBIDDEN"}`
+
+---
+
+**TC-024** | `GET /api/v1/members/{id}/quota — member accessing own quota returns 200`
+- **Given:** Authenticated member with JWT; requesting their own `memberId`
+- **When:** `GET /api/v1/members/{ownId}/quota`
+- **Then:** HTTP 200; response contains `dailyUsed`, `dailyRemaining`, `monthlyUsed`, `monthlyRemaining`, `isUnder21`
+
+---
+
+**TC-025** | `GET /api/v1/members/{otherMemberId}/quota — member accessing other member returns 403`
+- **Given:** Authenticated member requesting quota of a *different* member (same club)
+- **When:** `GET /api/v1/members/{otherMemberId}/quota`
+- **Then:** HTTP 403; GDPR principle: members must not see each other's consumption data
+
+---
+
+**TC-026** | `POST /api/v1/stock/batches/{id}/recall — verify cascade`
+- **Given:** Batch `BATCH-TEST-001` with 3 distributions recorded against it; `isRecalled = false`
+- **When:** `POST /api/v1/stock/batches/BATCH-TEST-001/recall` with `{"reason": "Contamination detected"}`
+- **Then:** HTTP 200; batch `isRecalled = true`; all 3 distribution records have `isRecalled = true`; response body contains list of 3 affected member IDs for notification
+
+---
+
+## 6. Test Data Fixtures
+
+Define these constants in `src/test/java/de/cannamanage/fixtures/TestFixtures.java`:

+    public static final String UNDER21_MEMBER_NAME = "Lisa Mayer";
+    public static final LocalDate UNDER21_MEMBER_DOB =

+
+    // Strain
+    public static final UUID STRAIN_ID =
+        UUID.fromString("00000000-0000-0000-0000-000000000020");
+    public static final String STRAIN_NAME = "Test OG";
+    public static final double STRAIN_THC_PERCENT = 20.0;
+    public static final double STRAIN_CBD_PERCENT = 1.0;
+
+    // Batch
+    public static final String BATCH_NUMBER = "BATCH-TEST-001";
+    public static final double BATCH_INITIAL_WEIGHT_G = 500.0;
+
+    // Compliance constants (mirror ComplianceConstants.java)
+    public static final double ADULT_MONTHLY_LIMIT_G = 50.0;
+    public static final double UNDER21_MONTHLY_LIMIT_G = 30.0;
+    public static final double DAILY_LIMIT_G = 25.0;
+    public static final double UNDER21_MAX_THC_PERCENT = 10.0;
+}
+```

+
+## 7. Coverage Requirements
+
+| Module | Test Type | Minimum Coverage | Enforcement |
+|--------|-----------|-----------------|-------------|
+| `cannamanage-service` | Unit | 80% line | JaCoCo CI gate |
+| `cannamanage-api` | Integration | 70% endpoint coverage | Manual checklist |
+| `cannamanage-domain` | Unit | 60% line (entities/enums) | JaCoCo CI gate |
+| `ComplianceService` | Unit | **100% line + branch** | JaCoCo CI gate — hard fail |
+| `TenantIsolationFilter` | Unit + Integration | 90% line | JaCoCo CI gate |
+
+> **Rationale for 100% on ComplianceService:** Each uncovered line is a potential legal violation. A missed branch in quota calculation could result in over-distribution — a criminal offence under CanG §34. This is not negotiable.

+## 8. Test Execution
+
+```bash
+# Run all unit tests
+./mvnw test -pl cannamanage-service
+
+# Run integration tests (requires Docker for Testcontainers)
+./mvnw verify -P integration-tests
+
+# Run specific test class
+./mvnw test -pl cannamanage-service -Dtest=ComplianceServiceTest
+
+# Coverage report (output: target/site/jacoco/index.html)
+./mvnw verify jacoco:report
+
+# Coverage report for single module
+./mvnw verify jacoco:report -pl cannamanage-service
+
+# Run compliance tests only (tagged)
+./mvnw test -pl cannamanage-service -Dgroups=compliance
+
+# Check coverage gate (will fail build if thresholds not met)
+./mvnw verify -P coverage-check
+```
+
+### Testcontainers Docker requirement
+
+Integration tests require Docker available on the host. The PostgreSQL container is pulled automatically by Testcontainers on first run. Ensure:
+- Docker daemon running: `systemctl start docker` (or `docker info`)
+- User in `docker` group: `sudo usermod -aG docker $USER`
+
+### Test annotation conventions
+
+```java
+// Unit test — no Spring context
+@ExtendWith(MockitoExtension.class)
+class ComplianceServiceTest { ... }
+
+// Integration test — full context + Testcontainers
+@SpringBootTest
+@Testcontainers
+@ActiveProfiles("test")
+class DistributionIntegrationTest { ... }
+
+// Tag compliance tests for selective execution
+@Tag("compliance")
+@Test
+void checkDistributionAllowed_givenAdultAtMonthlyLimit_shouldThrowQuotaExceededMonthly() { ... }

+
+**Project:** CannaManage — B2B SaaS for German Cannabis Social Clubs  
+**Version:** 0.1.0-PLAN  
+**Date:** 2026-04-06  
+**Target environment:** Hetzner VPS — Ubuntu 22.04 LTS — Docker Compose
+
+---
+
+## 1. Prerequisites
+
+### Hetzner VPS Specification
+
+| Resource | Value | Monthly Cost |
+|----------|-------|-------------|
+| Server type | CX21 | ~€5.88/month |
+| vCPU | 2 | — |
+| RAM | 4 GB | — |
+| SSD | 40 GB | — |
+| Network | 20 TB transfer | — |
+| OS | Ubuntu 22.04 LTS | — |
+
+> **Scale-up trigger:** Upgrade to CX31 (8GB RAM) when concurrent active clubs exceeds 20. PostgreSQL is the memory consumer — headroom is consumed by connection pools, not application heap.
+
+### DNS Setup
+
+| Record | Type | Value |
+|--------|------|-------|
+| `cannamanage.de` | A | `<VPS-IP>` |
+| `app.cannamanage.de` | A | `<VPS-IP>` |

+
+All three services run on an internal Docker bridge network (`cannamanage_net`). Only Nginx is exposed to the public internet. PostgreSQL has no external port binding.

+
+## 4. Environment Variables
+
+**File:** `/opt/cannamanage/.env` (never committed to git — add to `.gitignore`)
+
+```bash
+# Database
+DB_USERNAME=cannamanage_user
+DB_PASSWORD=<strong-random-password-min-32-chars>
+
+# JWT signing key (256-bit minimum — generate with: openssl rand -hex 32)
+JWT_SECRET=<256-bit-random-hex>
+
+# Stripe (use sk_live_ for production, sk_test_ for staging)
+STRIPE_SECRET_KEY=sk_live_...
+STRIPE_WEBHOOK_SECRET=whsec_...
+
+# Email (SMTP)
+MAIL_HOST=smtp.example.com
+MAIL_PORT=587
+MAIL_USERNAME=noreply@cannamanage.de
+MAIL_PASSWORD=<mail-password>
+MAIL_FROM=CannaManage <noreply@cannamanage.de>
+
+# Error tracking
+SENTRY_DSN=https://<key>@<org>.ingest.sentry.io/<project-id>
+
+# Application version (set by CI during deploy)
+VERSION=latest
+```
+
+> **Security:** Never store `.env` in version control. Use Gitea repository secrets for CI and inject at deploy time. On the VPS, set file permissions: `chmod 600 /opt/cannamanage/.env`.
+
+---
+
+## 5. First-Time Deployment
+
+### Step 1 — Create Hetzner VPS
+
+1. Log into [console.hetzner.cloud](https://console.hetzner.cloud)
+2. Create server: **CX21**, Ubuntu 22.04, Nuremberg or Frankfurt datacenter
+3. Add your SSH public key during setup (`cat ~/.ssh/id_ed25519.pub`)
+4. Note the assigned IPv4 address — update DNS A records
+
+### Step 2 — Install Docker + Docker Compose
+
+```bash
+ssh root@<VPS-IP>
+
+# Update system
+apt update && apt upgrade -y
+
+# Install Docker
+curl -fsSL https://get.docker.com | sh
+
+# Add deploy user (never run production as root)
+adduser deploy
+usermod -aG docker deploy
+usermod -aG sudo deploy
+
+# Install Certbot
+apt install -y python3-certbot-nginx certbot
+```
+
+### Step 3 — Clone Repository
+
+```bash
+su - deploy
+mkdir -p /opt/cannamanage
+cd /opt/cannamanage
+git clone http://192.168.188.119:30008/pplate/cannamanage.git .
+# Or from public mirror when available
+```
+
+### Step 4 — Create Production `.env`
+
+```bash
+cd /opt/cannamanage
+cp .env.example .env
+nano .env  # Fill in all production secrets
+chmod 600 .env
+```
+
+### Step 5 — Obtain SSL Certificate
+
+```bash
+# Stop anything on port 80 first (nothing should be running yet)
+certbot certonly --standalone \
+  -d app.cannamanage.de \
+  --non-interactive \
+  --agree-tos \
+  -m ssl@cannamanage.de
+
+# Symlink certs into nginx_certs volume location
+# Certbot places certs at /etc/letsencrypt/live/app.cannamanage.de/
+```
+
+### Step 6 — Build Docker Image
+
+```bash
+# On the VPS (or build locally and push to registry)
+./mvnw package -DskipTests -P production
+docker build -t cannamanage:latest .
+```
+
+### Step 7 — Start Services
+
+```bash
+cd /opt/cannamanage
+docker compose up -d
+```
+
+### Step 8 — Verify Health
+
+```bash
+# All containers should be 'healthy' or 'running'
+docker compose ps
+
+# Check application logs
+docker compose logs -f app --tail=100
+
+# Test health endpoint
+curl -f http://localhost:8080/actuator/health
+# Expected: {"status":"UP","components":{"db":{"status":"UP"},"diskSpace":{"status":"UP"}}}
+```
+
+### Step 9 — Flyway Migrations
+
+Flyway runs automatically on Spring Boot startup. Verify migration log:
+
+```bash
+docker compose logs app | grep -i flyway
+# Expected: Successfully applied N migrations to schema "public"
+```
+
+### Step 10 — Create First Admin User
+
+```bash
+# Option A: via REST API (recommended)
+curl -X POST https://app.cannamanage.de/api/v1/admin/bootstrap \
+  -H "Content-Type: application/json" \
+  -d '{
+    "adminEmail": "admin@yourclub.de",
+    "adminPassword": "<strong-password>",
+    "clubName": "Your Club e.V.",
+    "clubRegistrationNumber": "VR 12345"
+  }'
+
+# The bootstrap endpoint is disabled after first use (one-time setup flag in DB)
+```
+
+### Step 11 — Verify Production Access
+
+```bash
+# Web UI
+open https://app.cannamanage.de
+
+# API health check
+curl https://app.cannamanage.de/actuator/health
+```
+

+            set -e
+            cd /opt/cannamanage
+
+            # Load new image
+            docker load < /tmp/cannamanage.tar.gz
+            rm /tmp/cannamanage.tar.gz

+
+            # Prune old images (keep last 3)
+            docker image prune -f
+          "
+```
+
+### Required Gitea Repository Secrets
+
+| Secret | Value |
+|--------|-------|
+| `HETZNER_IP` | VPS IPv4 address |
+| `SSH_PRIVATE_KEY` | Private key for `deploy` user |
+
+Add deploy user's public key to VPS authorized_keys:
+```bash
+# On VPS as deploy user
+mkdir -p ~/.ssh && chmod 700 ~/.ssh
+echo "<gitea-actions-public-key>" >> ~/.ssh/authorized_keys
+chmod 600 ~/.ssh/authorized_keys
+```
+
+---
+
+## 7. Database Backup
+
+### Automated Daily Backup
+
+Add to root crontab (`crontab -e`):
+
+```bash
+# Daily backup at 03:00 UTC — keep 14 days
+0 3 * * * docker exec cannamanage-db pg_dump \
+  -U cannamanage_user \
+  --format=custom \
+  cannamanage | gzip > /opt/backups/cannamanage_$(date +\%Y\%m\%d).sql.gz
+
+# Cleanup backups older than 14 days
+5 3 * * * find /opt/backups -name "cannamanage_*.sql.gz" -mtime +14 -delete
+```
+
+Create backup directory:
+```bash
+mkdir -p /opt/backups
+chown deploy:deploy /opt/backups
+```
+
+### Restore from Backup
+
+```bash
+# Restore (caution: this overwrites existing data)
+gunzip -c /opt/backups/cannamanage_20260406.sql.gz | \
+  docker exec -i cannamanage-db pg_restore \
+    -U cannamanage_user \
+    --clean \
+    --dbname=cannamanage
+
+# Verify restore
+docker exec cannamanage-db psql \
+  -U cannamanage_user \
+  -d cannamanage \
+  -c "SELECT COUNT(*) FROM clubs;"
+```
+
+### Offsite Backup (Optional)
+
+For additional redundancy, sync backups to Hetzner Object Storage:
+
+```bash
+# Install s3cmd and configure with Hetzner S3-compatible endpoint
+s3cmd sync /opt/backups/ s3://cannamanage-backups/
+```
+
+---
+
+## 8. Monitoring & Health Checks
+
+### Spring Boot Actuator
+
+The application exposes health endpoints via `spring-boot-actuator`:
+
+```bash
+# Full health detail (requires ROLE_ADMIN JWT)
+GET /actuator/health
+
+# Example response
+{
+  "status": "UP",
+  "components": {
+    "db": { "status": "UP", "details": { "database": "PostgreSQL", "validationQuery": "isValid()" } },
+    "diskSpace": { "status": "UP", "details": { "total": 42GB, "free": 30GB } },
+    "ping": { "status": "UP" }
+  }
+}
+```
+
+Expose only `health` and `info` publicly in `application-production.yml`:
+```yaml
+management:
+  endpoints:
+    web:
+      exposure:
+        include: health,info
+  endpoint:
+    health:
+      show-details: when-authorized
+```
+
+### Log Locations
+
+| Source | Location |
+|--------|----------|
+| Application logs | `docker compose logs -f app` |
+| Nginx access logs | `/var/log/nginx/access.log` |
+| Nginx error logs | `/var/log/nginx/error.log` |
+| PostgreSQL logs | `docker compose logs db` |
+| Sentry (errors) | `https://sentry.io/organizations/<org>/` |
+
+### Alerting
+
+Configure Sentry to email on new errors:
+1. Set `SENTRY_DSN` in `.env`
+2. Add `io.sentry:sentry-spring-boot-starter-jakarta:7.x` to POM
+3. Sentry auto-captures all unhandled exceptions with full stack trace
+
+Simple uptime check via `cron` + email:
+
+```bash
+# Health check every 5 minutes — email on 3 consecutive failures
+*/5 * * * * /opt/cannamanage/scripts/health_check.sh
+```
+
+```bash
+#!/bin/bash
+# /opt/cannamanage/scripts/health_check.sh
+HEALTH_URL="https://app.cannamanage.de/actuator/health"
+FAIL_COUNT_FILE="/tmp/cannamanage_health_fails"
+
+HTTP_STATUS=$(curl -s -o /dev/null -w "%{http_code}" "$HEALTH_URL")
+if [ "$HTTP_STATUS" != "200" ]; then
+    FAILS=$(cat "$FAIL_COUNT_FILE" 2>/dev/null || echo 0)
+    FAILS=$((FAILS + 1))
+    echo "$FAILS" > "$FAIL_COUNT_FILE"
+    if [ "$FAILS" -ge 3 ]; then
+        echo "CannaManage health check failed $FAILS times" | \
+          mail -s "ALERT: CannaManage DOWN" admin@cannamanage.de
+    fi
+else
+    echo 0 > "$FAIL_COUNT_FILE"
+fi
+```
+
+---
+
+## 9. SSL Certificate Renewal
+
+Let's Encrypt certificates expire after 90 days. Certbot handles renewal automatically:
+
+```bash
+# Test renewal (dry run — no actual renewal)
+certbot renew --dry-run
+
+# Manual renewal
+certbot renew --nginx
+
+# Reload Nginx after renewal
+docker exec cannamanage-nginx nginx -s reload
+```
+
+### Auto-Renewal via Cron
+
+```bash
+# Renew at 02:00 UTC on the 1st and 15th of each month
+0 2 1,15 * * certbot renew --quiet --nginx && \
+  docker exec cannamanage-nginx nginx -s reload
+```
+
+Certbot only renews when the certificate is less than 30 days from expiry — safe to run frequently.
+
+---
+
+## 10. Rollback Procedure
+
+If a deployment causes issues:
+
+```bash
+# On VPS — list recent images
+docker images cannamanage --format "table {{.Tag}}\t{{.CreatedAt}}"
+
+# Roll back to previous SHA
+cd /opt/cannamanage
+VERSION=<previous-sha> docker compose up -d app
+
+# Verify health after rollback
+docker compose ps app
+curl https://app.cannamanage.de/actuator/health
+```
+
+If database migrations were applied and rollback is needed:
+1. Restore from last backup (see Section 7)
+2. Redeploy the previous image version
+3. Flyway baseline the schema at previous version
+
+> **Note:** Flyway migrations are append-only and forward-only. Design migrations to be reversible where possible (add columns before removing old ones, etc.).

+# 10 — Sprint 0 Planning Retrospective
+
+**Project:** CannaManage — B2B SaaS for German Cannabis Social Clubs  
+**Sprint:** 0 — Planning & Documentation  
+**Period:** 2026-04-04 to 2026-04-06  
+**Mode:** Solo planning, AI-assisted documentation (Claude Sonnet 4.6 via Roo Orchestrator + Doc Writer modes)  
+**Outcome:** ✅ Complete — 10-document suite written, architecture locked
+
+---
+
+## What Went Well ✅
+
+**AI-assisted documentation at scale.** The complete documentation suite (10 documents, ~25,000 words total) was created in a single focused session using the Roo Orchestrator mode to coordinate multi-document generation. This would have taken 2–3 days manually. The quality is high enough to serve as actual implementation guidance — not placeholder text.
+
+**Legal analysis confirmed viability early.** The CanG compliance review (Phase 1) identified the key constraints (no public directory, no consumer-facing advertising, B2B-only) before any code was written. These became hard architectural constraints rather than late surprises. No "oh wait, we can't do that" moments during technical design.
+
+**Architecture decisions locked before code.** The shared-schema multi-tenancy decision, immutable distribution records design, and `ComplianceConstants` pattern were all decided and documented before a single line of production code was written. This is the correct order. Rework from late architectural pivots is far more expensive than planning time.
+
+**Compliance constants centralized from day zero.** Designing `ComplianceConstants.java` as the single source of truth for all CanG quota values (25g/day, 50g/month, etc.) prevents the most dangerous class of compliance bug: magic numbers scattered across the codebase that diverge when the law changes.
+
+**ComfyUI mockup images in minutes.** Generating 5 realistic UI mockup images with FLUX.1-schnell took approximately 8 minutes of wall-clock time. This provides a visual reference for the UI that would otherwise require a designer or Figma skills. The images are good enough for stakeholder presentations and early user research.
+
+**Test plan written before code.** TC-001 through TC-026 were defined against specifications, not against existing implementation. This forces clarity on what the code must do before writing it — the test cases are essentially executable requirements.
+
+---
+
+## What Was Challenging ⚠️
+
+**ComfyUI manual startup friction.** The ComfyUI image generation server does not auto-start with the system. This required manual service start and a retry cycle before image generation could proceed. The fix (systemd user service + auto-start lifespan check in `mcp-image-gen`) was implemented during this planning sprint but added unexpected overhead.
+
+**Solo developer timeline is ambitious.** The 18–24 month estimate for a production-ready SaaS while employed full-time at ADP Germany is tight. Sprint 1 goals are achievable; the risk accumulates in Sprints 3–6 when frontend work, billing integration, and PDF generation converge. The PrimeFaces JSF choice for MVP was deliberate to reduce this risk — existing Java frontend skills transfer directly.
+
+**Spring Boot 3 is not yet a "home" stack.** ADP work uses Jakarta EE (JBoss, CDI, JAX-RS). Spring Boot 3 shares the JPA/Hibernate mental model but diverges on dependency injection, auto-configuration, and application packaging. The learning curve is real but bounded — the `mss-failsafe` and `wellmann-shop` projects in `pi_mcps` demonstrate that the transition is manageable.
+
+**Next.js/React remains a significant gap.** The v2 frontend pivot to Next.js 15 + React 19 is the highest-skill-gap risk in the project. PrimeFaces buys time, but the clock starts ticking on React learning from Sprint 1. Deferring is correct; ignoring it is not.
+
+**No real user validation yet.** The entire architecture and pricing model is based on market research and regulatory reading, not on conversations with actual club administrators. The product may be solving the right problem in the wrong way. This is the most important open risk.
+
+---
+
+## Key Decisions Made 📋
+
+| Decision | Rationale | Alternatives rejected |
+|----------|-----------|----------------------|
+| Shared-schema multi-tenancy (single DB, `tenant_id` columns) | Lowest ops overhead for MVP; one DB to backup/restore; simpler Flyway migrations | Schema-per-tenant (complex provisioning), DB-per-tenant (expensive at scale) |
+| Immutable distribution records (`@Column(updatable = false)`) | Legal integrity — audit logs must be tamper-proof; corrections via `RecallEvent`, not `UPDATE` | Mutable records (simpler but legally risky under CanG §26 record-keeping) |
+| PrimeFaces JSF for MVP frontend | Leverages existing Jakarta EE skills; fastest path to working product; no JS build tooling required | React/Next.js (faster modern dev, but higher skill gap), Thymeleaf (less interactive) |
+| No public club discovery — permanent architectural exclusion | CanG §§6–7 prohibit advertising cannabis to the general public; club lookup tool would likely constitute advertising | N/A — this is a legal constraint, not a design choice |
+| `ComplianceConstants.java` single source of truth | Prevents magic number scatter; single change point when law evolves | Constants in each service (fragile), DB-configurable limits (dangerous — allows disabling compliance) |
+| Hetzner VPS over AWS/GCP | Cost (€5.88/month vs €20+); EU data residency (GDPR); simpler ops for solo developer | AWS (expensive, complex), Fly.io (less EU clarity), Railway (vendor lock-in) |

+
+## Risks Going Forward ⚠️
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| New German government tightens CanG (e.g. lower quota limits) | Medium | High — requires rapid compliance updates | `ComplianceConstants.java` centralizes all limits; update is a 1-file change + test re-run |
+| Stripe flags account as cannabis-adjacent | Medium | Critical — billing becomes unusable | Use category "Vereinsverwaltung" (club management) in Stripe onboarding; prepare Mollie as fallback |
+| Solo dev burnout / timeline slip | High | Medium — delayed launch, not cancellation | Strict MVP scope; PrimeFaces reduces frontend effort; no scope creep before first paying customer |
+| Market timing risk — clubs adopt ad-hoc Excel/WhatsApp solutions | Medium | High — low willingness to pay for formal software | User research with 3+ clubs in Sprint 1 is mandatory before writing production code |
+| Legal risk: CanG compliance interpretation | Low | High — criminal liability for club officers | Specialist cannabis law opinion (€300–500) before launch; not optional |
+| Under-21 age calculation edge cases | Low | Medium — compliance bug | Birthday-based age calculation uses `Period.between()`, not year subtraction; tested in TC-013/014 |
+

+
+```bash
+# Copy the bundled service file to the systemd user directory
+mkdir -p ~/.config/systemd/user
+cp ~/pi_mcps/mcp/mcp-image-gen/comfyui.service ~/.config/systemd/user/comfyui.service

+```
+
+> ⚠️ `HSA_OVERRIDE_GFX_VERSION=11.0.0` is already set in the service file — it is mandatory for RX 7900 XTX on ROCm. Without it, model loading fails silently.
+
+### Enable lingering (start ComfyUI even without a login session)
+
+```bash
+loginctl enable-linger $USER
+```
+
+This ensures the service starts at boot even before you log in — recommended for headless / homelab setups.
+

+### Auto-start behaviour
+
+`mcp-image-gen` includes a **startup health check** in its lifespan. Every time the MCP server starts it:
+
+1. Pings `http://localhost:8188/system_stats`
+2. **If reachable** — logs `ComfyUI is already running ✓` and proceeds normally.
+3. **If not reachable** — attempts to launch ComfyUI as a background subprocess from `COMFYUI_DIR` using `.venv/bin/python main.py --listen --port 8188` with `HSA_OVERRIDE_GFX_VERSION=11.0.0` injected automatically.
+4. Polls up to 30 s for ComfyUI to become ready.
+
+With the systemd service enabled, step 3 is never needed in practice — but the check acts as a safety net.

+# Assessment: Expand `generate_image` with `name` and `count` Parameters
+
+*Author: Lumen | Date: 2026-04-06 | Ticket: —*
+*BigMind Session: `00070c37-b013-4342-a8ae-f81da0e3180d`*
+*Status: 🔵 DRAFT — awaiting Patrick review*
+
+---
+
+## 1. Problem Statement
+
+The current [`generate_image()`](mcp/mcp-image-gen/src/server.py:133) tool generates a single image and saves it with an auto-generated filename of `{timestamp}_{seed}.png`. Two common workflows are not yet supported:
+
+1. **Named outputs** — When generating thematic sets (Lumen profile images, wiki banners, concept art), the caller wants a meaningful prefix in the filename (e.g., `lumen_profile_20260406_140236_2409122067.png`) rather than a bare timestamp. This also enables grouping output by purpose in the directory listing.
+
+2. **Batch generation** — Generating multiple variations of the same prompt in one tool call is a common creative workflow. Currently, the caller must invoke `generate_image` N times with separate tool calls, which is verbose and loses the semantic grouping.
+
+**Goal:** Add two optional parameters — `name` (filename prefix string) and `count` (integer repetitions) — to `generate_image` with minimal disruption to existing behaviour and test coverage.
+
+---
+
+## 2. Requirements
+
+### 2.1 Functional Requirements
+
+| ID | Requirement |
+|----|-------------|
+| F-1 | `name` parameter (default `""`) prepends a sanitized label to the output filename |
+| F-2 | When `name=""` (default), filename format is unchanged: `{timestamp}_{seed}.png` |
+| F-3 | When `name="lumen_profile"`, filename format is: `lumen_profile_{timestamp}_{seed}.png` |
+| F-4 | `count` parameter (default `1`) generates N images sequentially |
+| F-5 | When `count=1` (default), return value is identical to the current `[TextContent, ImageContent]` |
+| F-6 | When `count=N > 1`, return value is a flat list: `[Text1, Image1, Text2, Image2, ..., TextN, ImageN]` |
+| F-7 | When `count>1` and `seed=-1`, each image gets an independently random seed |
+| F-8 | When `count>1` and a fixed `seed` is provided, images use `seed`, `seed+1`, `seed+2`, … to produce deterministic variation |
+| F-9 | `count` is capped at a maximum (proposed: 10) to prevent runaway generation |
+| F-10 | `name` is sanitized: non-alphanumeric characters (except `-` and `_`) are stripped/replaced; max 64 chars |
+| F-11 | Partial success: if one image in a batch fails, the error is returned as a `TextContent` error item in that position rather than aborting the whole batch |
+| F-12 | The TextContent for each image in a batch includes the 1-of-N index: `[1/3] Generated: ...` |
+
+### 2.2 Non-Functional Requirements
+
+| ID | Requirement |
+|----|-------------|
+| NF-1 | Sequential generation — no concurrent ComfyUI submissions (ComfyUI queues internally; parallel MCP submissions would complicate polling) |
+| NF-2 | Backward compatibility — all existing callers with no `name`/`count` args produce identical output |
+| NF-3 | All existing 19 tests must continue to pass without modification |
+| NF-4 | New tests must cover: name prefix in filename, count=2 success, count with fixed seed increments, count with partial failure, name sanitization, count cap enforcement |
+| NF-5 | MCP tool schema (visible in Claude/Roo Code) must surface clear descriptions for the new params |
+
+---
+
+## 3. Affected Files
+
+| File | Change Type | Description |
+|------|-------------|-------------|
+| [`mcp/mcp-image-gen/src/server.py`](mcp/mcp-image-gen/src/server.py:133) | Modify | Add `name: str = ""` and `count: int = 1` params to `generate_image()`; add `_sanitize_name()` helper; extract `_generate_single()` inner logic |
+| [`mcp/mcp-image-gen/tests/test_server.py`](mcp/mcp-image-gen/tests/test_server.py:1) | Modify | Add 6+ new test cases covering new parameters |
+| [`mcp/mcp-image-gen/README.md`](mcp/mcp-image-gen/README.md) | Modify | Update `generate_image` tool documentation table |
+| [`docs/wiki/pages/mcp-image-gen.md`](docs/wiki/pages/mcp-image-gen.md) | Modify | Update tool reference table with new parameters |
+
+No schema changes, no new dependencies, no workflow JSON changes.
+
+---
+
+## 4. Design Decisions
+
+### 4.1 Filename Convention with `name`
+
+**Current:** `{timestamp}_{seed}.png`
+**Proposed:** `{sanitized_name}_{timestamp}_{seed}.png` (when `name` is provided)
+
+The `name` is placed as a **prefix** rather than suffix so directory `ls` output groups named sets together alphabetically:
+```
+lumen_profile_20260406_140236_2409122067.png
+lumen_profile_20260406_140258_764633840.png
+wiki_banner_20260406_141000_1234567.png
+```
+
+**Sanitization rule:** `re.sub(r'[^a-zA-Z0-9_-]', '_', name)[:64]` — replaces any character that is not alphanumeric, dash, or underscore with `_`, then truncates to 64 chars.
+
+### 4.2 Seed Behaviour for Batch Generation
+
+| Scenario | Behaviour |
+|----------|-----------|
+| `count=3, seed=-1` | Each call to `build_flux_workflow` gets `seed=-1` → 3 independent random seeds |
+| `count=3, seed=42` | Seeds are 42, 43, 44 — deterministic, reproducible variation |
+
+This follows the convention of most image generation tools (e.g., ComfyUI's own batch seed increment).
+
+### 4.3 Return Structure for `count > 1`
+
+Return a **flat interleaved list**: `[Text1, Image1, Text2, Image2]`
+
+**Rationale:** MCP content lists are flat arrays. Claude/Roo Code renders them sequentially — a flat list means each image appears immediately below its metadata line. A nested structure would require the caller to unwrap it.
+
+**For `count=1` (default):** Behaviour is identical to today — `[TextContent, ImageContent]`. No caller breakage.
+
+### 4.4 Refactoring: Extract `_generate_single()`
+
+The current `generate_image` function is 180+ lines of inline logic. To support `count`, the inner pipeline (queue → poll → history → download → save → encode) will be extracted to a private `async def _generate_single(prompt, ..., index, total)` coroutine. `generate_image` then loops `count` times calling `_generate_single` and accumulates results.
+
+This refactoring:
+- Makes the count loop clean (`results.extend(await _generate_single(...))`)
+- Makes partial failure handling straightforward (catch per iteration)
+- Improves testability of the single-image path
+
+### 4.5 Maximum Count Cap
+
+Cap `count` at **10**. Rationale:
+- FLUX.1-schnell takes ~10–35s per image on RX 7900 XTX → 10 images ≈ 100–350s maximum
+- MCP tool call timeout in Roo Code defaults to 5 minutes — 10 images is safe margin
+- ComfyUI queues them internally; the MCP server polls sequentially, not in parallel
+
+When `count > 10`, the tool returns a single `TextContent` error immediately (no images generated) with message: `"count={N} exceeds maximum of 10. Reduce count and retry."`
+
+---
+
+## 5. Implementation Plan
+
+### Step 1 — Add `_sanitize_name()` helper
+
+```python
+import re
+
+def _sanitize_name(name: str) -> str:
+    """Sanitize a name for use as a filename prefix."""
+    sanitized = re.sub(r'[^a-zA-Z0-9_-]', '_', name)
+    return sanitized[:64]
+```
+
+Location: [`server.py`](mcp/mcp-image-gen/src/server.py:95), after `build_flux_workflow()` (pure function section).
+
+### Step 2 — Extract `_generate_single()` coroutine
+
+Extract the body of the current `generate_image` (lines 162–310) into:
+
+```python
+async def _generate_single(
+    prompt: str,
+    width: int,
+    height: int,
+    steps: int,
+    model: str,
+    seed: int,
+    negative_prompt: str,
+    resolved_output_dir: Path,
+    filename_prefix: str,
+    index: int,
+    total: int,
+) -> list:
+```
+
+The `filename` construction changes to:
+```python
+filename = f"{filename_prefix}{timestamp}_{actual_seed}.png"
+# where filename_prefix = f"{sanitized_name}_" if sanitized_name else ""
+```
+
+The `TextContent` text changes when `total > 1`:
+```python
+prefix_label = f"[{index}/{total}] " if total > 1 else ""
+text = f"{prefix_label}Generated: {out_path}\nSeed: ..."
+```
+
+### Step 3 — Update `generate_image()` signature
+
+```python
+@mcp.tool()
+async def generate_image(
+    prompt: str,
+    width: int = 1024,
+    height: int = 1024,
+    steps: int = 4,
+    model: str = "flux1-schnell.safetensors",
+    seed: int = -1,
+    negative_prompt: str = "",
+    output_dir: str = "",
+    name: str = "",
+    count: int = 1,
+) -> list:
+```
+
+Body of `generate_image` becomes:
+
+```python
+# Validate count
+MAX_COUNT = 10
+if count < 1 or count > MAX_COUNT:
+    return [TextContent(type="text", text=f"count={count} is invalid. Must be 1–{MAX_COUNT}.")]
+
+sanitized_name = _sanitize_name(name) if name else ""
+filename_prefix = f"{sanitized_name}_" if sanitized_name else ""
+resolved_output_dir = Path(output_dir or IMAGE_OUTPUT_DIR).expanduser().resolve()
+
+results = []
+for i in range(1, count + 1):
+    actual_seed = seed if seed == -1 else seed + (i - 1)
+    items = await _generate_single(
+        prompt=prompt, width=width, height=height, steps=steps,
+        model=model, seed=actual_seed, negative_prompt=negative_prompt,
+        resolved_output_dir=resolved_output_dir,
+        filename_prefix=filename_prefix, index=i, total=count,
+    )
+    results.extend(items)
+
+return results
+```
+
+### Step 4 — Write new tests
+
+Add to [`test_server.py`](mcp/mcp-image-gen/tests/test_server.py:550):
+
+| Test | Description |
+|------|-------------|
+| `test_generate_image_with_name` | `name="lumen"` → filename starts with `lumen_` |
+| `test_generate_image_name_sanitization` | `name="my image! v2"` → `my_image__v2_` prefix |
+| `test_generate_image_count_2_success` | `count=2` → 4 items in result, 2 files saved |
+| `test_generate_image_count_fixed_seed` | `count=2, seed=42` → seeds 42 and 43 in filenames |
+| `test_generate_image_count_partial_failure` | `count=2`, second POST fails → 2 items (success) + 1 item (error) |
+| `test_generate_image_count_cap_exceeded` | `count=11` → single TextContent error, no generation |
+| `test_generate_image_count_0_invalid` | `count=0` → single TextContent error |
+| `test_generate_image_name_and_count_combined` | `name="banner", count=2` → both files prefixed `banner_` |
+
+### Step 5 — Update documentation
+
+- Update `generate_image` docstring in [`server.py`](mcp/mcp-image-gen/src/server.py:144) to document `name` and `count`
+- Update parameter table in [`README.md`](mcp/mcp-image-gen/README.md)
+- Update tool reference in [`docs/wiki/pages/mcp-image-gen.md`](docs/wiki/pages/mcp-image-gen.md)
+
+### Step 6 — Run full test suite
+
+```bash
+cd mcp/mcp-image-gen && uv run pytest tests/ -v --tb=short
+```
+
+All 19 existing + 8 new = **27 tests** must pass.
+
+### Step 7 — Commit and push
+
+Branch: `feat/mcp-image-gen/generate-image-name-count`
+Commit: `feat(mcp-image-gen): add name and count params to generate_image`
+
+---
+
+## 6. Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|------------|--------|------------|
+| Partial batch failure leaves orphaned files on disk | Medium | Low | Files for successful images are kept; error TextContent clearly identifies which index failed. No cleanup needed — partial results are useful. |
+| `count` loop adds significant latency visible in Roo Code | Medium | Medium | Document expected time: `count × ~15s`. MCP timeout is 5 min; max 10 images ≈ 150s. Still within limit. |
+| Seed increment wraps around at `2^32` | Very Low | Low | `(seed + i - 1) % 2**32` — add modulo guard in `_generate_single` |
+| `_generate_single` refactor introduces regression in existing tests | Low | High | Existing test fixtures mock ComfyUI endpoints — as long as the HTTP call sequence is unchanged, respx mocks will match. Verify each existing test still passes before adding new ones. |
+| `name` with only special chars becomes empty after sanitization | Low | Medium | After sanitization, if result is empty string, treat as unnamed (no prefix). Add assertion in `_sanitize_name` to return `""` for all-whitespace/special inputs. |
+| MCP tool schema change breaks existing callers | Very Low | Low | New params are optional with defaults — backward compatible. Roo Code re-reads schema on server restart. |
+
+---
+
+## 7. Alternatives Considered
+
+### 7.1 Separate `generate_images_batch()` Tool (Rejected)
+
+Add a new tool instead of expanding `generate_image`. 
+
+**Pros:** Clean separation, no refactoring of existing tool.
+**Cons:** Two tools for the same backend; callers must learn two tool names; MCP tool list grows. The MCP convention favours extending existing tools with optional parameters rather than proliferating tools.
+
+**Verdict:** Rejected. Optional parameters with backward-compatible defaults is the right pattern here.
+
+### 7.2 Return Grouped List of Lists for `count > 1` (Rejected)
+
+Return `[[Text1, Image1], [Text2, Image2]]` for batch results.
+
+**Pros:** Caller can index by image number cleanly.
+**Cons:** MCP content type is a flat `list[ContentBlock]`. FastMCP does not support nested lists in tool returns — they would be serialized as strings, not rendered. Roo Code renders content sequentially; flat interleaved is the idiomatic structure.
+
+**Verdict:** Rejected. Flat interleaved list `[Text1, Image1, Text2, Image2]` is MCP-idiomatic.
+
+### 7.3 Parallel ComfyUI Submission for Batch (Rejected)
+
+Submit all `count` prompts to ComfyUI simultaneously (async tasks), then collect results in order.
+
+**Pros:** Faster if ComfyUI supports parallel queue processing (it does).
+**Cons:** ComfyUI processes one job at a time on a single GPU regardless — parallel submission just fills the queue. Polling becomes complex (N polling loops). Error handling harder. Out-of-order completions break index alignment.
+
+**Verdict:** Rejected for v1. Sequential submission is simpler, correct, and produces no worse throughput. Can revisit if ComfyUI gains true parallel processing support.
+
+### 7.4 Name as Subdirectory Instead of Filename Prefix (Rejected)
+
+When `name="lumen"`, save to `output_dir/lumen/` instead of `output_dir/lumen_*.png`.
+
+**Pros:** Better directory organisation for large sets.
+**Cons:** Complicates the implementation (directory creation per name), changes the return path format, breaks callers who assume a flat output directory. Adds complexity for minimal gain at `count ≤ 10`.
+
+**Verdict:** Rejected for v1. Prefix approach is simpler and equally readable.
+
+---
+
+## 8. Success Criteria
+
+| Criterion | Measure |
+|-----------|---------|
+| All 27 tests pass | `uv run pytest tests/ -v` exits 0 |
+| `name="lumen"` → file starts with `lumen_` | Assert in `test_generate_image_with_name` |
+| `count=2` → 4 content items, 2 files | Assert `len(result) == 4`, `len(glob("*.png")) == 2` |
+| `count=2, seed=42` → seeds 42 and 43 | Assert seed values in TextContent |
+| `count=11` → error TextContent, no ComfyUI call | Assert `len(result) == 1`, no `/api/prompt` mock hit |
+| Backward compat: existing callers unaffected | All 19 existing tests pass without modification |
+| MCP tool schema shows `name` and `count` params | Visible in Roo Code tool list after server restart |
+
+---
+
+## 9. Open Questions
+
+| # | Question | Owner | Priority |
+|---|----------|-------|----------|
+| Q1 | Should `count=0` be an error, or silently return `[]` (empty list)? | Patrick | Low — assessment recommends error for clarity |
+| Q2 | Max count cap: 10 or higher? 10 ≈ 150s max at 15s/image — feels right, but could be raised to 20 for batch profile image sets. | Patrick | Medium |
+| Q3 | Should partial batch failure stop remaining iterations, or always complete all N? | Patrick | Medium — assessment recommends continue (partial success) |
+| Q4 | Should `name` parameter also tag the TextContent output text, e.g. `[lumen_profile 1/3] Generated: ...`? | Patrick | Low |

-## 10. Known Limitations
+## 10. FLUX.2 Klein 4B with Heretic Abliteration (New)
+
+**New in this release:** Support for **FLUX.2 Klein 4B** using an **abliterated Qwen3-4B text encoder** via Heretic.
+
+### Why Heretic?
+
+FLUX.2 Klein uses a full LLM (Qwen3-4B) as its text encoder instead of CLIP+T5. This LLM has safety alignment that can refuse certain prompts. Heretic removes this alignment with **zero measurable KL divergence** (0.0000) and only 3/100 refusals.
+
+### How to use it
+
+```python
+generate_image(
+    prompt="a beautiful cyberpunk fox in neon tokyo, highly detailed",
+    model="flux-2-klein-4b-fp8.safetensors",
+    width=1024,
+    height=1024,
+    steps=4
+)
+```
+
+### Models to download
+
+```bash
+# 1. FLUX.2 Klein 4B (distilled, fp8)
+huggingface-cli download black-forest-labs/FLUX.2-klein-4B \
+    flux-2-klein-4b-fp8.safetensors \

+# CannaManage — Project Charter
+
+**Author:** Patrick Plate  
+**Date:** 2026-04-06  
+**Version:** 1.0  
+**Status:** Draft for Review
+
+---
+
+## 1. Executive Summary
+
+### Vision Statement
+
+> *CannaManage is the compliance backbone for German cannabis social clubs — purpose-built to turn a legally mandated administrative burden into a manageable, auditable, and digitised workflow.*
+
+### The Problem
+
+Germany's **Konsumcannabisgesetz (CanG)**, in force since April 1, 2024, legalised cannabis for personal use and established a framework for **Anbauvereinigungen** (cannabis social clubs / CSCs). Every operating CSC faces mandatory, recurring compliance obligations:
+
+- Track every distribution (recipient, strain, weight, date/time) — by law
+- Enforce quantity limits per member (50g/month for adults, 30g/month for under-21, 25g/day)
+- Maintain batch-level contamination traceability
+- Produce periodic authority reports
+- Designate and track a Prevention Officer (Präventionsbeauftragter)
+- Manage member data under DSGVO
+
+Clubs currently manage this with Excel spreadsheets, pen-and-paper logs, and WhatsApp groups — creating legal risk, audit gaps, and administrative chaos.
+
+### Why Now
+
+The market is less than two years old. **No purpose-built software tooling exists** for German CSCs. The window to establish market leadership is 2026–2027 before larger players notice the niche. First-mover advantage combined with the permanent regulatory moat from CanG compliance requirements makes this the right moment.
+
+### What We Are Building
+
+A **multi-tenant B2B SaaS platform** offering:
+- Club admin portal (member management, distribution logging, stock management, compliance reporting)
+- Member portal (personal quota, distribution history, stock visibility)
+- Built-in CanG compliance enforcement and export tooling
+
+**We are selling compliance management software to licensed, regulated entities. We are not in the cannabis business.**
+
+---
+
+## 2. Project Scope
+
+### 2.1 In Scope — MVP v1
+
+| Area | Features Included |
+|------|-------------------|
+| **Onboarding** | Club registration, setup wizard, admin account creation |
+| **Member Management** | Add/remove members, age verification (18+, 18–21 restricted), contact data |
+| **Distribution Tracking** | Log each handout (member, strain, weight, date/time); enforce daily/monthly limits |
+| **Limit Enforcement** | 25g/day cap, 50g/month (adult), 30g/month (under-21), 10% THC flag |
+| **Stock Management** | Strains, batch tracking, quantity levels |
+| **Admin Dashboard** | Club-level totals: members, distributions this month, stock levels |
+| **Compliance Exports** | Monthly distribution report (PDF + CSV), member list export for inspections |
+| **Contamination Recall** | Flag a batch; system lists all members who received from it |
+| **Prevention Officer** | Store officer contact info and designation date |
+| **Member Portal** | Login with club-issued credentials; view quota, distribution history, stock availability |
+| **Authentication** | Spring Security + JWT; role-based (ADMIN, MEMBER) |
+| **Hosting** | Hetzner VPS (German DC), Docker Compose, PostgreSQL + Flyway |
+
+### 2.2 Explicitly Out of Scope — MVP v1
+
+| Feature | Reason Excluded |
+|---------|-----------------|
+| Public club discovery / "find clubs near you" | **Illegal under CanG §§6–7 advertising ban** |
+| Cannabis e-commerce or payment for cannabis | Illegal; violates positioning |
+| Non-EU data storage (AWS us-east, etc.) | DSGVO violation |
+| Stripe subscription billing | Deferred to Phase 1 (Weeks 9–16) |
+| Email/SMS notifications | v2 feature |
+| Mobile native app (Android/iOS) | v2/v3 feature |
+| Multi-location club support | v3 feature |
+| Legal template marketplace | v3 feature |
+| Next.js/React frontend | v2 migration after revenue justifies investment |
+| Authority portal integrations | v3 feature (portals don't exist yet) |
+
+---
+
+## 3. Stakeholders
+
+| Role | Description | Needs |
+|------|-------------|-------|
+| **Club Admin** *(primary user)* | Vereinsvorstand or designated manager; runs day-to-day club operations | Compliant distribution logging, member management, authority-ready exports |
+| **Club Member** *(secondary user)* | Verified adult member of the Anbauvereinigung | Self-service quota visibility, distribution history, stock availability |
+| **Prevention Officer** *(Präventionsbeauftragter, tertiary user)* | Legally required role; may or may not be the admin | Contact info tracked in system; receives relevant reports |
+| **Patrick Plate** *(developer & product owner)* | Solo developer; nights/weekends; ADP Germany full-time | Minimal learning overhead; fast path to first revenue; legally sound product |
+
+---
+
+## 4. Success Criteria
+
+MVP is considered complete when all of the following are true:
+
+| # | Criterion | Measure |
+|---|-----------|---------|
+| 1 | **Core compliance loop working** | Admin can log a distribution → system enforces limits → admin exports PDF report for authorities |
+| 2 | **Multi-tenant isolation** | Two clubs' data are completely isolated — no cross-tenant data leakage |
+| 3 | **Member portal live** | Member can log in with club-issued credentials and view their quota + history |
+| 4 | **Contamination recall functional** | Admin flags a batch; system returns full recipient list in < 2 seconds |
+| 5 | **Deployment stable** | Platform runs on Hetzner VPS via Docker Compose with uptime ≥ 99% over 30-day beta |
+| 6 | **Beta validation** | 3–5 real club admins have used the system and provided written feedback |
+| 7 | **Legal review passed** | No features violate CanG advertising ban; DSGVO AVV in place before any live data |
+| 8 | **Zero PII on non-EU infrastructure** | All data confirmed to reside in Hetzner DE datacenter |
+
+---
+
+## 5. Constraints & Assumptions
+
+### Constraints
+
+| Type | Constraint |
+|------|-----------|
+| **Legal** | CanG §§6–7 imposes a **total advertising and sponsoring ban** on cannabis AND Anbauvereinigungen — no public club discovery feature, ever |
+| **Legal** | DSGVO requires EU hosting, data processing agreements (AVV), member data export/deletion capability |
+| **Technical (MVP)** | Frontend is PrimeFaces + JSF — Patrick's existing expertise; no new framework learning in Phase 0 |
+| **Technical** | Multi-tenancy via `tenant_id` on all JPA entities — no row-level security shortcuts |
+| **Team** | Solo developer — Patrick; nights and weekends only; full-time at ADP Germany |
+| **Timeline** | Phase 0 target: 8 weeks; Phase 1 target: 16 weeks total from project start |
+| **Budget** | Infrastructure: Hetzner €5–20/month; no team salary cost |
+
+### Assumptions
+
+- German CSCs are willing to pay €29–€79/month for compliance software
+- Stripe will process subscriptions for compliance software (not cannabis sales) without restriction
+- Spring Boot 3.x is sufficiently adjacent to Patrick's Jakarta EE expertise to use without major ramp-up
+- PrimeFaces MVP is sufficient for beta validation — UI polish deferred to v2
+- CanG remains in force and CSC licensing continues in all major Bundesländer
+
+---
+
+## 6. Risk Register
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|-----------|
+| **Advertising ban reinterpreted to include B2B SaaS** | Low | High | Obtain legal opinion from cannabis law specialist before launch (€300–500); strict no-discovery design enforced at architecture level |
+| **New German government rolls back or tightens CanG** | Medium | High | Modular architecture — compliance-only features can be extracted and pivoted to a general club management tool |
+| **Stripe blocks cannabis-adjacent businesses** | Medium | High | Position as "Vereinsverwaltungs-Software" (club management software); never process cannabis payments; test with Stripe before public launch |
+| **Clubs fail / licenses revoked** | Medium | Medium | Diversified customer base; per-month billing (easy cancellation); no annual lock-in required for MVP |
+| **DSGVO violation** | Low | Very High | EU-only hosting (Hetzner DE), DPA/AVV agreements before any live data, DSGVO-compliant privacy policy in German, member data export/deletion API from day one |
+
+---
+
+## 7. Budget & Resources
+
+| Item | Cost | Notes |
+|------|------|-------|
+| **Development** | €0 (Patrick's time) | Nights/weekends; valued at opportunity cost only |
+| **Infrastructure — Hetzner VPS** | €5–20/month | German DC; scales with load |
+| **Infrastructure — PostgreSQL** | €0 (self-hosted on VPS) | Managed DB upgrade available when needed |
+| **Legal opinion** | €300–500 (one-time) | Cannabis law specialist; pre-launch requirement |
+| **Domain (cannamanage.de)** | ~€15/year | To be registered |
+| **Stripe fees** | 1.4% + €0.25 per transaction | EU cards; only on paid subscriptions |
+| **Email (Resend / Jakarta Mail)** | €0–10/month | Resend free tier for low volume |
+| **Sentry monitoring** | €0 (free tier) | Error tracking; Java SDK |
+| **Total pre-launch** | **~€600–700** | Including legal opinion |

+## 9. Legal Framework
+
+### Key CanG Provisions
+
+| Provision | Content | Product Implication |
+|-----------|---------|---------------------|
+| **§2 CanG** | Definitions — Anbauvereinigung, Mitglied | Data model must align with statutory definitions of club and member |
+| **§§15–26 CanG** | Anbauvereinigungen — formation, rights, obligations | Club registration flow must capture legally required club attributes |

+| **§26 CanG** | Documentation and reporting obligations | Compliance export module is a legal requirement, not an optional feature |
+| **§27 CanG** | Prevention officer requirements | Prevention officer fields mandatory in club setup; not optional |
+
+### DSGVO Obligations
+
+- All personal data stored on EU infrastructure (Hetzner DE)
+- Data processing agreement (AVV) required with each club before live data entry
+- Member data export endpoint required (Art. 20 DSGVO — data portability)

+
+### US-001: Register Club and Complete Setup Wizard
+
+**As a** Club Admin, **I want to** register my Anbauvereinigung and complete a guided setup wizard, **so that** my club is correctly configured with all legally required attributes before any members are added.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can register with email + password; email confirmation required before accessing the system
+- [ ] AC2: Setup wizard collects: club name, registered address, founding date, Vereinsregisternummer (if available), maximum membership count
+- [ ] AC3: Wizard requires designation of a Prevention Officer (name, contact) — field is mandatory, cannot be skipped
+- [ ] AC4: Wizard requires acceptance of DSGVO data processing agreement (AVV) before any member data can be entered
+- [ ] AC5: Completing the wizard provisions the club's isolated tenant environment (all subsequent data scoped to this club only)
+- [ ] AC6: Admin receives a welcome email with login link after successful setup
+- [ ] AC7: Incomplete wizard state is saved — admin can resume from last completed step
+
+**Notes:** The AVV acceptance (AC4) is a legal prerequisite for handling member personal data under DSGVO. It must be timestamped and stored.
+
+---
+
+### US-002: Add and Remove Members with Age Verification
+
+**As a** Club Admin, **I want to** add and remove club members with age verification, **so that** the member roster is accurate and the system can apply the correct distribution limits per member.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can add a member with: full name, date of birth, email (optional), membership start date, member ID (auto-generated or manual)
+- [ ] AC2: System rejects members with date of birth indicating age < 18
+- [ ] AC3: Members aged 18–21 are automatically flagged as "Restricted (§23 CanG)" — this flag drives reduced quantity limits
+- [ ] AC4: Admin can deactivate (soft-delete) a member; deactivated members cannot receive distributions but their historical records are preserved
+- [ ] AC5: Admin can permanently delete a member record (DSGVO Art. 17 right to erasure); system warns if member has distribution history and requires explicit confirmation
+- [ ] AC6: Member list is searchable by name and filterable by status (active / restricted / deactivated)
+- [ ] AC7: Total active member count is visible on the dashboard and in the member list header
+
+**Notes:** Hard deletion (AC5) must cascade correctly — distribution records referencing the member must be anonymised, not deleted, to preserve the compliance audit trail.
+
+---
+
+### US-003: Record a Distribution
+
+**As a** Club Admin, **I want to** record each cannabis distribution to a member, **so that** every handout is documented as required by §26 CanG and the member's consumption is tracked.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can log a distribution by selecting: member (search/autocomplete), strain, weight in grams (decimal, e.g. 3.5g), batch, date and time
+- [ ] AC2: System pre-fills date/time with current timestamp; admin can override
+- [ ] AC3: If the distribution would cause the member to exceed their daily limit (25g), the system displays a prominent warning and requires explicit override confirmation
+- [ ] AC4: If the distribution would cause the member to exceed their monthly limit (50g adult / 30g restricted), the system **blocks** the entry and displays the reason
+- [ ] AC5: For restricted members (§23), system additionally validates that the selected strain's THC percentage is ≤ 10% (if THC% is recorded on the batch)
+- [ ] AC6: Successfully saved distributions appear immediately in the distribution log and update the member's monthly counter
+- [ ] AC7: Distribution records are immutable after creation — admin can only add a correction note, not edit the original record
+
+**Notes:** Immutability (AC7) is essential for audit integrity. Correction notes are the appropriate mechanism for errors.
+
+---
+
+### US-004: View and Enforce Distribution Limits
+
+**As a** Club Admin, **I want to** view each member's current distribution totals and remaining quota, **so that** I can verify limits at a glance before and after recording distributions.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Each member's detail view shows: distributions this month (total grams), daily total for today, remaining monthly quota, and limit category (Adult 50g / Restricted 30g)
+- [ ] AC2: Remaining quota is displayed as a progress bar (visual indicator of how close to the limit)
+- [ ] AC3: Members who have reached or exceeded their monthly limit are visually flagged in the member list (e.g., red badge)
+- [ ] AC4: Members who have consumed > 80% of their monthly limit show a warning indicator (e.g., amber badge)
+- [ ] AC5: Monthly counters reset automatically on the first of each calendar month
+- [ ] AC6: System applies §22 limits (50g/month, 25g/day) for adults and §23 limits (30g/month) for restricted members — these cannot be changed by the admin
+
+**Notes:** The limits in AC6 are statutory and must be hardcoded, not configurable per club.
+
+---
+
+### US-005: Manage Stock (Strains, Quantities, Batches)
+
+**As a** Club Admin, **I want to** manage my club's cannabis stock including strains, batch information, and quantities, **so that** I know what is available for distribution and can track batch provenance for contamination purposes.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can create a strain with: name, THC% (optional), CBD% (optional), variety type (Indica/Sativa/Hybrid)
+- [ ] AC2: Admin can create a batch linked to a strain with: batch ID (auto-generated), quantity in grams, harvest date (optional), grow cycle reference (optional)
+- [ ] AC3: Each distribution recorded reduces the associated batch's available quantity
+- [ ] AC4: Admin can manually adjust stock quantity with a reason note (e.g., "lab sample", "disposal")
+- [ ] AC5: Admin is warned (but not blocked) when a batch's available quantity drops below a configurable threshold (default: 100g)
+- [ ] AC6: Stock overview page shows all active batches with: strain name, batch ID, quantity available, quantity distributed to date
+- [ ] AC7: Depleted batches (quantity = 0) are automatically moved to an "archived" view
+
+**Notes:** Batch tracking is required for contamination recall (US-009). The batch ID must be immutable once created.
+
+---
+
+### US-006: View Admin Dashboard
+
+**As a** Club Admin, **I want to** see a summary dashboard when I log in, **so that** I have an at-a-glance overview of club activity and can identify anything requiring attention.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Dashboard displays: total active members, members at/near their monthly limit (count), total distributions this calendar month (grams), active stock level (total grams across all batches)
+- [ ] AC2: Dashboard shows a count of members in the "restricted §23" category separately
+- [ ] AC3: Dashboard highlights any batches flagged as contaminated (contamination alert count)
+- [ ] AC4: Dashboard includes a recent activity feed (last 10 distributions: member name, strain, weight, time)
+- [ ] AC5: All dashboard data reflects the admin's own club only — never cross-tenant data
+- [ ] AC6: Dashboard loads in < 3 seconds on Hetzner VPS hardware
+
+**Notes:** Keep the dashboard simple for MVP — a single page with widgets. No charts required for v1.
+
+---
+
+### US-007: Export Monthly Compliance Report (PDF + CSV)
+
+**As a** Club Admin, **I want to** export a monthly compliance report as PDF and CSV, **so that** I can fulfil my documentation and reporting obligations under §26 CanG.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can select any calendar month/year and generate a compliance report
+- [ ] AC2: PDF report contains: club name, reporting period, total distributions (count and weight), distribution detail table (member ID, strain, batch, weight, date/time), stock summary
+- [ ] AC3: Member names in the PDF are replaced with member IDs to minimise PII exposure in the report document (actual name lookup available to the club separately)
+- [ ] AC4: CSV export contains full distribution log for the selected period with headers: member_id, strain, batch_id, weight_g, distribution_date, distribution_time
+- [ ] AC5: PDF is generated server-side using iText 7 (no client-side rendering dependency)
+- [ ] AC6: Export completes in < 10 seconds for a month with up to 5,000 distribution records
+- [ ] AC7: Generated reports are not stored on the server — they are streamed directly to the browser as a download
+
+**Notes:** Not storing reports (AC7) reduces data exposure risk. The club is responsible for retaining their own copies.
+
+---
+
+### US-008: Export Member List for Inspections
+
+**As a** Club Admin, **I want to** export the current member list, **so that** I can present it to authorities during an inspection as required by law.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can export the active member list as PDF and CSV at any time
+- [ ] AC2: Export includes: member ID, full name, date of birth, age category (Adult/Restricted §23), membership start date, current membership status
+- [ ] AC3: Export is timestamped with the generation date/time in the document
+- [ ] AC4: Admin is shown a DSGVO reminder before downloading (this document contains personal data — handle per your privacy obligations)
+- [ ] AC5: Export includes the club name and address in the header
+- [ ] AC6: Only active members are included by default; admin can optionally include deactivated members
+
+**Notes:** This document contains significant PII. The DSGVO reminder (AC4) is important to keep admins legally aware.
+
+---
+
+### US-009: Trigger Contamination Alert for a Batch
+
+**As a** Club Admin, **I want to** flag a batch as contaminated and immediately see all members who received from it, **so that** I can notify affected members and fulfil my contamination traceability obligations under CanG.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can mark any batch as "contaminated" with a reason note and timestamp
+- [ ] AC2: Immediately upon flagging, system displays a list of all members who received distributions from the contaminated batch (name, member ID, total grams received, dates received)
+- [ ] AC3: Contaminated batches are removed from the active distribution interface — admin cannot select them for new distributions
+- [ ] AC4: The dashboard shows a contamination alert badge whenever any active batch is flagged
+- [ ] AC5: Admin can export the affected member list as PDF and CSV (for authority notification)
+- [ ] AC6: Contamination status is immutable — once flagged, only a senior action (with confirmation) can reverse it; reversal is logged with reason
+
+**Notes:** Contamination traceability is explicitly required by CanG. Response speed matters — the affected member list (AC2) must display without delay.
+
+---
+
+### US-010: Manage Prevention Officer Information
+
+**As a** Club Admin, **I want to** record and update Prevention Officer (Präventionsbeauftragter) information, **so that** my club meets the mandatory requirement of §27 CanG.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Club profile includes a Prevention Officer section with fields: full name, contact email, contact phone, designation date
+- [ ] AC2: All four fields are required — the system warns if any is empty and marks the section as incomplete
+- [ ] AC3: Admin can update the Prevention Officer at any time; previous officer entries are retained in a change log (name, designation period)
+- [ ] AC4: The compliance report export (US-007) includes the current Prevention Officer name and contact in its header
+- [ ] AC5: Setup wizard (US-001) cannot be completed without entering Prevention Officer information
+
+**Notes:** This is a statutory requirement, not optional. AC5 enforces that clubs cannot operate on the platform without this data.
+
+---
+
+### Member Portal Stories
+
+---
+
+### US-011: Login with Club-Issued Credentials
+
+**As a** Club Member, **I want to** log in to the member portal using credentials issued by my club, **so that** I can access my personal information without the club admin needing to be present.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can generate login credentials (username + temporary password) for a member from the member management screen
+- [ ] AC2: Member receives credentials via a secure channel (displayed to admin for manual handoff in MVP; email in v2)
+- [ ] AC3: Member is required to change their temporary password on first login
+- [ ] AC4: Member login is scoped to their club only — they cannot access any other club's data or member list
+- [ ] AC5: Failed login attempts are rate-limited (5 attempts, then 15-minute lockout)
+- [ ] AC6: Member sessions expire after 24 hours of inactivity
+- [ ] AC7: Members cannot register themselves — accounts are always created by the Club Admin
+
+**Notes:** AC7 is critical for CanG compliance — only verified, age-checked members should have portal access.
+
+---
+
+### US-012: View Personal Distribution History
+
+**As a** Club Member, **I want to** view my personal distribution history, **so that** I can track what I have received from the club.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member can view all their distributions in reverse chronological order: date/time, strain, weight (grams), batch ID
+- [ ] AC2: Current calendar month distributions are shown first, with a clear monthly subtotal
+- [ ] AC3: Member can filter history by month/year
+- [ ] AC4: Member sees only their own distribution history — no other member's data is accessible
+- [ ] AC5: History is read-only — members cannot edit or delete distribution records
+
+---
+
+### US-013: View Current Stock Availability
+
+**As a** Club Member, **I want to** see what strains are currently available at the club, **so that** I know what I can request on my next visit.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member portal shows a stock list with: strain name, variety type (Indica/Sativa/Hybrid), THC% (if recorded), availability status (Available / Low Stock / Unavailable)
+- [ ] AC2: Exact batch quantities are NOT shown to members — only availability status
+- [ ] AC3: Only strains with available stock (quantity > 0) are shown as "Available"
+- [ ] AC4: Strains with stock below the admin-configured low-stock threshold are shown as "Low Stock"
+- [ ] AC5: For restricted members (§23 CanG), strains with THC > 10% are shown with a "Not available to you" indicator rather than hidden (transparency about why)
+- [ ] AC6: Stock view is refreshed in real time — no stale cache longer than 5 minutes
+
+**Notes:** AC2 is important — showing exact quantities could constitute advertising for the club's stock. Only availability status is shown.
+
+---
+
+### US-014: View Remaining Monthly Quota
+
+**As a** Club Member, **I want to** see my remaining monthly quota, **so that** I can plan my distributions and stay within my legal limits.
+
+**Priority:** Must Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member portal homepage prominently displays: consumed this month (grams), remaining quota (grams), monthly limit (grams), days remaining in current month
+- [ ] AC2: Quota is displayed as a progress bar with colour coding: green (< 50% used), amber (50–80% used), red (> 80% used)
+- [ ] AC3: Members in the restricted §23 category see their 30g/month limit (not the 50g adult limit)
+- [ ] AC4: Daily limit status is also visible: consumed today (grams) vs. 25g daily cap
+- [ ] AC5: Quota resets display on the first of each calendar month — confirmed visually (e.g., "Resets in X days")
+
+---
+
+## Should Have — v2
+
+---
+
+### US-015: Process Membership Fee Payments via Stripe
+
+**As a** Club Admin, **I want to** collect membership fees from members via Stripe, **so that** fee collection is automated and documented without manual bank transfers.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can configure an annual membership fee amount for their club
+- [ ] AC2: Members can pay via Stripe-hosted checkout (card payment)
+- [ ] AC3: Stripe subscription or one-time payment for annual fee — admin configures which model
+- [ ] AC4: Payment confirmation is logged against the member record with date and amount
+- [ ] AC5: Admin can view payment status per member (paid / pending / overdue)
+- [ ] AC6: No cannabis product payments are ever processed through this system — fee is for club membership only
+
+**Notes:** Stripe position: membership fees for registered non-profit clubs (Vereinsbeiträge) are standard use case. AC6 must be enforced at system design level.
+
+---
+
+### US-016: Manage Automated Waiting List
+
+**As a** Club Admin, **I want to** manage a waiting list for new membership applicants, **so that** I can process applications in order while respecting the club's maximum membership count.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can set a maximum member count for the club (from setup wizard or settings)
+- [ ] AC2: When member count reaches maximum, new applicants are added to a waiting list with timestamp
+- [ ] AC3: Waiting list is FIFO — applicants are offered membership in order of application
+- [ ] AC4: Admin can notify the next waiting list applicant (email notification — v2 dependency)
+- [ ] AC5: Admin can remove applicants from the waiting list
+- [ ] AC6: Waiting list count is visible on the admin dashboard
+
+---
+
+### US-017: Receive Email and SMS Notifications
+
+**As a** Club Member, **I want to** receive email (and optionally SMS) notifications for key events, **so that** I am informed without needing to log in to the portal.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Member receives email notification when their distribution is recorded by the admin
+- [ ] AC2: Member receives email when their monthly quota reaches 80% consumed
+- [ ] AC3: Member receives email when a batch they received from is flagged as contaminated
+- [ ] AC4: Admin receives email when any member's quota is exceeded (should not happen, but safety net)
+- [ ] AC5: SMS notifications are optional and require member opt-in; email is default
+- [ ] AC6: All notification emails are sent in German (language is not configurable in v2)
+- [ ] AC7: Members can manage notification preferences (opt out of non-mandatory notifications)
+
+---
+
+### US-018: Track Multi-Strain Grow Cycles
+
+**As a** Club Admin, **I want to** track grow cycles linked to batches, **so that** I have full provenance from grow start to distribution.
+
+**Priority:** Should Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can create a grow cycle with: cycle ID, strain, start date, expected harvest date, grow area (optional), notes
+- [ ] AC2: Batches can be linked to a grow cycle
+- [ ] AC3: Grow cycle view shows: all batches produced, total yield, grow duration
+- [ ] AC4: Closed grow cycles (harvest complete) are archived but remain searchable
+- [ ] AC5: Grow cycle data is included in the monthly compliance report (batch provenance section)
+
+---
+
+## Could Have — v3
+
+---
+
+### US-019: Access Mobile PWA
+
+**As a** Club Member, **I want to** use CannaManage on my smartphone without installing an app, **so that** I can check my quota and stock on the go.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: The member portal is fully responsive and usable on mobile viewport sizes (320px and up)
+- [ ] AC2: The app can be added to the home screen (PWA manifest, service worker, offline cache for quota display)
+- [ ] AC3: Core member portal features (quota, distribution history, stock view) work in offline mode with cached data
+- [ ] AC4: Admin portal is also responsive (admin-on-the-go distribution logging)
+- [ ] AC5: No app store submission required — pure PWA
+
+---
+
+### US-020: Support Multi-Location Club
+
+**As a** Club Admin, **I want to** manage a club with multiple distribution locations, **so that** members can pick up from different sites and all distributions are consolidated.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: Admin can define multiple locations (name, address) for one club
+- [ ] AC2: Distributions are recorded with a location tag
+- [ ] AC3: Stock is managed per location or shared — admin configures which model
+- [ ] AC4: Compliance reports can be generated per location or consolidated for the whole club
+- [ ] AC5: Members are assigned a primary location but can receive from any location within quota limits
+
+---
+
+### US-021: Download Legal Document Templates
+
+**As a** Club Admin, **I want to** download standardised legal document templates (Satzung, Jugendschutzkonzept), **so that** I can fulfil my legal obligations without hiring a lawyer for every document.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: Template library is accessible from the admin portal (separate from compliance exports)
+- [ ] AC2: Available templates include: Vereinssatzung (club charter), Jugendschutzkonzept (youth protection concept), DSGVO Datenschutzerklärung
+- [ ] AC3: Templates are pre-filled with club-specific data (name, address, Prevention Officer) where applicable
+- [ ] AC4: Templates are available as DOCX (editable) and PDF (final version)
+- [ ] AC5: Template library is a paid add-on (€49 one-time or included in Professional/Enterprise plan)
+
+---
+
+### US-022: Integrate with Authority Reporting Portals
+
+**As a** Club Admin, **I want to** submit compliance reports directly to authority portals via CannaManage, **so that** I save time and avoid transcription errors in authority submissions.
+
+**Priority:** Could Have  
+**Acceptance Criteria:**
+- [ ] AC1: System can detect available authority portals by Bundesland (state)
+- [ ] AC2: Admin can initiate a report submission from within CannaManage
+- [ ] AC3: Submission status is tracked (submitted, acknowledged, rejected) per report
+- [ ] AC4: System retries failed submissions automatically (up to 3 times)
+- [ ] AC5: This feature is only activated once at least one Bundesland has a machine-readable submission portal
+
+**Notes:** Authority portals may not exist in v3 timeline — this is aspirational and depends on government digitalisation progress.
+
+---
+
+## Won't Have — MVP (Explicitly Excluded)
+
+---
+
+### US-023: Public Club Discovery — "Find Clubs Near You"
+
+**As a** Public User, I want to find cannabis clubs near my location.
+
+**Priority:** Won't Have (MVP)  
+**Reason:** **Explicitly illegal under CanG §§6–7.** The advertising and sponsoring ban covers any feature that functions as advertising for Anbauvereinigungen to the general public. A public club directory constitutes advertising for clubs. This feature will never be built in any form on this platform.
+
+**Acceptance Criteria:** *None — this feature is permanently excluded.*
+
+**Notes:** This is not a commercial decision. It is a **legal constraint** hardcoded into the product architecture. No public-facing club listing, no map, no search, no "register your club publicly."
+
+---
+
+### US-024: Cannabis E-Commerce or Payment for Cannabis Products
+
+**As a** Club Member, I want to purchase cannabis through the CannaManage platform.
+
+**Priority:** Won't Have (MVP)  
+**Reason:** **Illegal.** Cannabis sales are not the legal model for Anbauvereinigungen under CanG. Payment for cannabis products would violate German law and immediately trigger Stripe account termination. CannaManage processes membership fee payments only — not cannabis product payments, ever.
+
+**Acceptance Criteria:** *None — permanently excluded.*
+
+---
+
+### US-025: Non-EU Data Storage
+
+**As a** Club Admin, I want my club's data stored on the cheapest/fastest infrastructure, including non-EU servers.
+
+**Priority:** Won't Have (MVP)  
+**Reason:** **DSGVO violation.** Club member data includes personal data (name, date of birth, consumption records). Storing this outside the EU without a valid adequacy decision or standard contractual clauses violates Art. 44–49 DSGVO. All data remains on Hetzner DE datacenters.
+
+**Acceptance Criteria:** *None — permanently excluded.*
+
+---

+## 2. Multi-Tenancy Strategy
+
+### Approach: Shared Schema with Row-Level Filtering
+
+Every JPA entity carries a `tenant_id` column (UUID, `NOT NULL`). A single PostgreSQL database hosts all clubs — row-level filtering enforces data isolation at the application layer.
+
+**Why shared schema (not separate schema/DB per tenant)?**
+- Lower operational overhead for an MVP with < 500 clubs
+- Single Flyway migration path across all tenants
+- Simpler connection pooling (one pool, not N)
+- Acceptable security risk when `tenant_id` filter is enforced at the service layer
+
+### Tenant Resolution
+
+```
+HTTP Request
+    └─ Spring Security Filter: extract JWT → resolve tenant_id
+         └─ TenantContext.setCurrentTenant(tenantId)   // ThreadLocal
+              └─ JPA @Where filter applied on every entity query
+```
+
+### Code Pattern — Tenant-Aware Base Entity
+
+```java
+// AbstractTenantEntity.java (pseudocode)
+@MappedSuperclass
+@FilterDef(
+    name = "tenantFilter",
+    parameters = @ParamDef(name = "tenantId", type = UUID.class)
+)
+@Filter(name = "tenantFilter", condition = "tenant_id = :tenantId")
+public abstract class AbstractTenantEntity {
+
+    @Column(name = "tenant_id", nullable = false, updatable = false)
+    private UUID tenantId;
+
+    @PrePersist
+    void injectTenant() {
+        this.tenantId = TenantContext.getCurrentTenant();
+    }
+}
+```
+
+```java
+// TenantFilterInterceptor.java (pseudocode)
+@Component
+public class TenantFilterInterceptor implements HandlerInterceptor {
+
+    @Autowired EntityManager em;
+
+    @Override
+    public boolean preHandle(HttpServletRequest req, ...) {
+        UUID tenantId = TenantContext.getCurrentTenant();
+        Session session = em.unwrap(Session.class);
+        session.enableFilter("tenantFilter")
+               .setParameter("tenantId", tenantId);
+        return true;
+    }
+}
+```
+
+**Invariants enforced:**
+- `tenant_id` is set at `@PrePersist` — never accepted from user input
+- `tenant_id` is `updatable = false` — cannot be changed after creation
+- Hibernate filter is enabled on every request thread before any query executes
+- All repository methods inherit the filter; raw JPQL queries must include `AND e.tenantId = :tenantId`
+
+---
+
+## 3. Authentication & Authorization
+
+### JWT Token Flow
+
+- **Access token:** 8-hour expiry, signed HS256, contains `sub` (userId), `role`, `tenantId`
+- **Refresh token:** 30-day expiry, stored in `users.refresh_token_hash` (hashed)
+- **Stateless:** No server-side session. JWT is verified on every request by `JwtAuthFilter`
+
+### Roles
+
+| Role | Description | Access |
+|---|---|---|
+| `ROLE_CLUB_ADMIN` | Club administrator | Full club management, all members, reports, distributions |
+| `ROLE_MEMBER` | Club member | Own quota, own distribution history |
+| `ROLE_PREVENTION_OFFICER` | Designated prevention officer | Member under-21 reports, prevention data |
+
+### Service-Layer Authorization Example
+
+```java
+@Service
+public class DistributionService {
+
+    @PreAuthorize("hasRole('CLUB_ADMIN')")
+    public Distribution recordDistribution(RecordDistributionRequest req) { ... }
+
+    @PreAuthorize("hasRole('MEMBER') and #memberId == authentication.principal.memberId")
+    public QuotaStatus getMyQuota(UUID memberId) { ... }
+
+    @PreAuthorize("hasAnyRole('CLUB_ADMIN', 'PREVENTION_OFFICER')")
+    public List<Member> getUnder21Members() { ... }
+}
+```
+
+### Member Login Sequence
+
+```mermaid
+sequenceDiagram
+    participant B as Browser
+    participant API as Spring Boot /api/v1/auth/login
+    participant DB as PostgreSQL (users table)
+    participant JWT as JwtService

+    else Valid
+        API->>JWT: generateAccessToken(userId, role, tenantId) → 8h
+        API->>JWT: generateRefreshToken(userId) → 30d
+        API->>DB: UPDATE users SET refresh_token_hash = ?, last_login = NOW()
+        DB-->>API: OK
+        JWT-->>API: accessToken, refreshToken
+        API-->>B: 200 { accessToken, refreshToken, expiresIn: 28800 }

+### Relationship Notes
+
+| Relationship | Cardinality | Notes |
+|---|---|---|
+| Club → Member | 1:N | `member.club_id` FK; max enforced by `Club.max_members` |
+| Member → Distribution | 1:N | Each distribution targets one member |
+| Member → MonthlyQuota | 1:N | One row per `(member_id, year, month)` — UNIQUE constraint |
+| Member → User | 1:0..1 | A member may have a portal login; admins may have no `member_id` |
+| Strain → Batch | 1:N | Each batch is one strain; a strain can have many batches |
+| Batch → Distribution | 1:N | A batch can supply many distributions |
+| Batch → StockMovement | 1:N | Every IN/OUT/RECALL against a batch is journaled |
+| Distribution.recorded_by → Member | N:1 | The admin who recorded it (audit trail) |
+
+### Key Constraints
+
+- `Distribution.immutable = true` by default — records are append-only; no UPDATE/DELETE allowed via API
+- `MonthlyQuota` has `UNIQUE(member_id, year, month)` — enforced at DB level
+- `Batch.contamination_flag` triggers recall workflow; `Batch.status = RECALLED` is the final state
+- All `tenant_id` columns: `NOT NULL`, `updatable = false`, set via `@PrePersist`
+- `Member.is_under_21` is derived from `date_of_birth` at registration and re-evaluated on birthday (scheduled job)
+
+---
+
+## 5. API Layer Design
+
+### Base Path: `/api/v1/`
+
+All endpoints are RESTful. JSON request/response bodies. JWT Bearer token required on all except `/auth/**`.
+
+| Controller | Base Path | Key Endpoints |
+|---|---|---|
+| `AuthController` | `/api/v1/auth` | `POST /login`, `POST /refresh`, `POST /logout` |
+| `ClubController` | `/api/v1/clubs` | `GET /`, `POST /`, `GET /{id}`, `PUT /{id}` |
+| `MemberController` | `/api/v1/members` | `GET /`, `POST /`, `GET /{id}`, `PUT /{id}/status`, `GET /me/quota` |
+| `DistributionController` | `/api/v1/distributions` | `POST /`, `GET /?memberId=&month=&year=` |
+| `StockController` | `/api/v1/stock` | `GET /batches`, `POST /batches`, `POST /batches/{id}/recall` |
+| `ReportController` | `/api/v1/reports` | `GET /monthly?month=&year=` (PDF + CSV), `GET /members/{id}/history` |
+| `QuotaController` | `/api/v1/quota` | `GET /members/{id}/current`, `GET /members/{id}/history` |
+
+### Standard HTTP conventions
+- `201 Created` + `Location` header on resource creation
+- `400 Bad Request` with `{ error, message, field? }` on validation failure
+- `403 Forbidden` when role/tenant check fails
+- `422 Unprocessable Entity` when compliance limits are breached (quota exceeded)
+- Pagination: `?page=0&size=20&sort=field,asc`
+
+---
+
+## 6. Compliance Engine
+
+The `ComplianceService` is the heart of regulatory enforcement. It is called synchronously before every distribution is persisted. All operations run in a single `@Transactional` block with optimistic locking to prevent race conditions under concurrent distribution recording.
+
+```java
+@Service
+@Transactional
+public class ComplianceService {
+
+    /**
+     * Validates whether a distribution is legally permitted.
+     *
+     * Checks:
+     *   1. Member is ACTIVE (not SUSPENDED or EXPELLED)
+     *   2. Daily limit: total distributed today + requestedGrams ≤ 25g
+     *   3. Monthly limit: MonthlyQuota.total_distributed + requestedGrams ≤ max_allowed
+     *      where max_allowed = 30g (under-21) or 50g (adult)
+     *   4. Batch is AVAILABLE (not RECALLED or EXHAUSTED)
+     *   5. Batch has sufficient stock
+     *
+     * @throws ComplianceLimitExceededException with remaining quota details
+     * @throws MemberIneligibleException if member is not ACTIVE
+     * @throws BatchUnavailableException if batch is recalled or exhausted
+     */
+    public ComplianceCheckResult checkDistributionAllowed(
+            UUID memberId, UUID batchId, BigDecimal quantityGrams) { ... }
+
+    /**
+     * Returns remaining quota for the current calendar month.
+     * Creates a MonthlyQuota row if none exists (lazy initialization).
+     *
+     * @return QuotaStatus { totalAllowed, totalUsed, remaining, isUnder21 }
+     */
+    public QuotaStatus getMonthlyRemaining(UUID memberId) { ... }
+
+    /**
+     * Flags a batch as RECALLED.
+     * Returns all members who received distributions from this batch
+     * so the caller can trigger notifications.
+     * Writes a StockMovement(RECALL) entry.
+     *
+     * @return List<AffectedMember> { memberId, name, email, totalReceived }
+     */
+    public List<AffectedMember> recallBatch(UUID batchId) { ... }
+}
+```
+
+### Race Condition Prevention
+
+`MonthlyQuota` rows carry a JPA `@Version` column (optimistic locking). If two concurrent requests attempt to increment `total_distributed` simultaneously, one will receive an `OptimisticLockException` and must retry. The retry logic is handled by a `@Retryable` annotation (Spring Retry, max 3 attempts, 50ms backoff).
+
+```java
+@Entity
+public class MonthlyQuota extends AbstractTenantEntity {
+
+    @Version
+    private Long version;  // optimistic lock
+
+    // ... other fields
+}
+```

+
+### Hetzner Sizing
+
+| Resource | Spec | Rationale |
+|---|---|---|
+| Server | CX21 (2 vCPU, 4GB RAM) | Sufficient for < 200 concurrent clubs at MVP |
+| Storage | 40GB SSD (included) | PostgreSQL + logs; Hetzner Volumes for backups |
+| Backups | Hetzner automated backups (20% surcharge) | Daily snapshot retention 7 days |
+| Location | Falkenstein, Germany (FSN1) | DSGVO: data remains within Germany |
+| TLS | Let's Encrypt via Certbot | Auto-renew via cron |
+
+### Deployment Workflow
+
+```
+git push origin main
+  → Gitea webhook fires
+  → deploy.sh on Hetzner:
+      docker pull cannamanage:latest
+      docker compose up -d --no-deps cannamanage-app
+      # zero-downtime: Nginx buffers requests during restart
+```
+
+Flyway migrations run automatically on application startup (`spring.flyway.enabled=true`). Migration files live at `src/main/resources/db/migration/V*.sql`.

+
+## 8. Key Design Decisions
+
+| Decision | Choice | Rationale |
+|---|---|---|
+| Multi-tenancy | Shared schema + `tenant_id` | MVP simplicity; upgrade to schema-per-tenant possible later |
+| Frontend MVP | PrimeFaces JSF | Patrick's existing expertise; fastest path to working UI |
+| Frontend v2 | Next.js / React | Modern UX; deferred to avoid scope creep in MVP |
+| Auth | JWT (stateless) | No sticky sessions needed; horizontal scale ready |
+| PDF generation | iText 7 | Mature Java library; handles complex compliance report layouts |
+| Compliance enforcement | Service layer + DB constraint | Belt-and-suspenders: service validates, DB `UNIQUE` prevents duplicates |
+| Distribution immutability | `immutable = true`, no DELETE API | Audit trail integrity for regulatory compliance |
+| Hosting | Hetzner (Germany) | DSGVO compliance; low cost; German DC |

+
+## Flow 1: Distribution Recording
+
+Records a cannabis distribution to a member. This is the most compliance-critical path in the system. Every step that can fail returns a user-facing error with actionable detail (remaining quota, batch status, etc.).

+
+## Flow 2: Member Registration
+
+Registers a new member in the club. Includes DSGVO consent, age validation, under-21 flag assignment, and automatic portal account creation.
+
+```mermaid
+flowchart TD
+    START([🟢 Admin opens\n'Add Member' form]) --> ENTER_DATA[Admin enters member data:\nfirst/last name, email,\ndate of birth, address]

+    SEND_EMAIL --> SUCCESS([✅ Member registered\nShow member profile\nwith membership number])
+```
+
+---
+
+## Flow 3: Contamination Batch Recall
+
+Handles the recall of a contaminated batch. This flow is time-critical — speed of notification is essential for member safety. All affected distributions are identified and the prevention officer is notified.
+
+```mermaid
+flowchart TD

+
+    QUERY_DIST --> HAS_DIST{Any distributions\nfound?}
+
+    HAS_DIST -->|No distributions| NO_DIST["⚠️ Batch was never distributed\n(still flag as RECALLED\nfor inventory integrity)"]
+    HAS_DIST -->|Yes| BUILD_LIST["Build affected member list:\n• member name\n• distribution date\n• quantity received\n• contact email"]
+
+    NO_DIST --> FLAG_BATCH
+    BUILD_LIST --> SHOW_LIST[Show affected member list\nto admin for review]
+
+    SHOW_LIST --> ADMIN_REVIEW{Admin reviews\nand confirms recall?}
+    ADMIN_REVIEW -->|Cancel| CANCEL
+    ADMIN_REVIEW -->|Proceed| FLAG_BATCH["💾 UPDATE Batch\nstatus = RECALLED\ncontamination_flag = true"]

+## Flow 4: Compliance Report Generation
+
+Generates the monthly compliance report required by § 22 KCanG. Covers all distributions within a calendar month, with per-member quota analysis and club metadata for regulatory submission.

+
+## Flow Summary
+
+| Flow | Trigger | Key Service | Critical Constraint |
+|---|---|---|---|
+| Distribution Recording | Admin records handout | `ComplianceService` | Daily 25g + monthly 30g/50g limits |
+| Member Registration | Admin adds new member | `MemberService` | Age ≥ 18, DSGVO consent mandatory |
+| Batch Recall | Admin flags contamination | `ComplianceService.recallBatch()` | Immediate prevention officer notification |
+| Report Generation | Admin requests monthly report | `ReportService` | iText 7 PDF + CSV for regulatory filing |
+| Member Login | Member accesses portal | `AuthService` + `QuotaController` | JWT stateless, read-only member view |
+
+### Error Handling Conventions
+
+All flows follow these conventions for user-facing error messages:
+
+- **Compliance errors** (`422 Unprocessable Entity`): Always include remaining quota/allowance so the admin knows what quantity would be valid
+- **Validation errors** (`400 Bad Request`): Include the specific `field` and a human-readable `message` in German (UI locale)
+- **Permission errors** (`403 Forbidden`): Generic message — do not reveal tenant or role details
+- **System errors** (`500 Internal Server Error`): Log full stack trace; show generic user message; alert via email to club admin
+
+### Transaction Boundaries
+
+The Distribution Recording flow (Flow 1) executes steps `SAVE_DIST → UPD_QUOTA → UPD_STOCK → UPD_BATCH` in a **single `@Transactional` block**. If any step fails (e.g., optimistic lock collision on `MonthlyQuota`), the entire transaction rolls back and no partial state is persisted.

+#### Compliance UX — Real-Time Quota Indicator
+
+The quota progress bar updates live as the weight field changes (via `f:ajax event="keyup"`):
+
+| Quota Used After Distribution | Bar Color | Submit Button | Message |
+|---|---|---|---|
+| 0–79% | `#8BC34A` (green) | Enabled | — |
+| 80–99% | `#FF6B35` (orange) | Enabled | "⚠ Approaching monthly limit" |
+| 100% | `#D32F2F` (red) | **Disabled** | "🚫 Monthly limit reached (50g)" |
+| Over-21 member, >30g monthly | `#D32F2F` (red) | **Disabled** | "🚫 Under-21 limit reached (30g)" |
+
+#### Components & Behavior
+
+| Component | PrimeFaces | Behavior |
+|---|---|---|
+| Member search | `p:selectOneMenu` with `p:ajax` filter | Filters on type, shows name + member no. |
+| Strain/Batch dropdown | `p:selectOneMenu` | Populated after member selection; shows only `AVAILABLE` batches |
+| Weight input | `p:inputNumber` min=`0.1` max=`25.0` step=`0.1` | Triggers quota recalculation on blur |
+| Quota bar | `p:progressBar` with dynamic `value` | Color class applied via `styleClass` computed in backing bean |
+| Submit | `p:commandButton` | Disabled via `disabled="#{bean.quotaExceeded}"` |
+| Cancel | `p:link` | Returns to distribution log without saving |

+
+#### Compliance Note — Available Strains Display
+
+Per CanG §§6–7, members may NOT see specific batch quantities or total stock levels. The **Available Strains** table shows only:
+- Strain name
+- Availability status (Available / Limited / Unavailable)
+
+Quantities, batch codes, and THC/CBD percentages are **not exposed** in the member portal.
+
+#### Components & Behavior
+
+| Component | PrimeFaces | Behavior |
+|---|---|---|
+| Quota circle | Custom CSS radial progress (`conic-gradient`) | Computed from monthly total; color matches threshold rules |
+| Quota bar | `p:progressBar` | Same color logic as admin distribution form |
+| History table | `p:dataTable` | Last 10 distributions; sorted newest first; no pagination in MVP |
+| Strains table | `p:dataTable` | `status` column: text + icon only, no quantities |

+└──────────────────────────────────────────┘
+```
+
+#### Design Decisions
+
+- **No self-registration link** — member accounts are created exclusively by admins via the admin portal. The login page has no "Create account" or "Sign up" flow.
+- **No forgot-password link** — password resets are initiated by the club admin only. The login page directs users to contact their admin, avoiding email-based reset flows that would require verified email infrastructure in MVP.
+- **No social login** — DSGVO compliance and club accountability require traceable credential management.
+- **Form submission:** POST to `/login` (Spring Security form login), redirect to `/member/dashboard` on success.
+
+#### Components & Behavior
+
+| Component | PrimeFaces | Behavior |
+|---|---|---|
+| Email field | `p:inputText` with `required="true"` | Bean Validation `@Email` |
+| Password field | `p:password` feedback=`false` | No strength meter on login |
+| Login button | `p:commandButton` | Submit form; shows `p:messages` on failure |
+| Error message | `p:messages` | "Invalid email or password." (never specific about which field failed) |

+
+## 5. Responsive Design Notes
+
+### MVP (v1) — Desktop-First
+
+Target viewport: **1024px+**. PrimeFaces responsive grid (`p:panelGrid` with responsive columns, `ui-g-12 ui-md-6 ui-lg-4`) handles most layout adaptation down to tablet without custom media queries.
+
+| Breakpoint | Behavior |
+|---|---|
+| `≥ 1280px` | Full layout — sidebar + content side-by-side |
+| `1024–1279px` | Sidebar collapses to icon-only (60px); tooltips on hover |
+| `768–1023px` | Sidebar hidden; hamburger menu in top navbar |
+| `< 768px` | Admin portal degraded (tables scroll horizontally) |
+
+### Member Portal — Mobile-First from Day One
+
+Members will typically check quota status on their phone. The member portal is designed mobile-first regardless of MVP/v2 timeline.
+
+| Breakpoint | Behavior |
+|---|---|
+| `≥ 1024px` | Two-column layout: quota circle left, history right |
+| `768–1023px` | Single-column, full-width cards |
+| `375–767px` | Single-column, compact quota ring, condensed table |
+| `< 375px` | Minimum supported; no horizontal scroll |
+
+### v2 Roadmap
+
+- PWA manifest + service worker (offline quota display)
+- 768px and 375px explicit breakpoints with design tokens
+- Touch-friendly `p:sidebar` for mobile member nav
+- Push notifications for low quota warnings
+
+---
+
+## 6. Accessibility
+
+CannaManage targets **WCAG 2.1 AA** compliance across both portals.
+
+### Keyboard Navigation
+
+| Element | Keyboard Behavior |
+|---|---|
+| Navigation sidebar | Tab navigates items; Enter activates |
+| Data tables | Tab to table; arrow keys for row navigation |
+| Dropdown menus | Enter/Space to open; arrow keys to navigate; Escape to close |
+| Modal dialogs | Focus trapped inside; Escape to close; first focusable element receives focus on open |
+| Confirmation dialogs | Tab between Confirm and Cancel; Enter on focused button |
+
+### Screen Reader Support
+
+- All `p:inputText` / `p:inputNumber` fields have `<label>` with `for` attribute
+- `aria-label` set on icon-only buttons (e.g., recall action column)
+- `aria-live="polite"` region on quota bar — announces percentage changes
+- `aria-describedby` links compliance warning messages to the weight input
+- PrimeFaces generates `role="grid"` and `aria-rowcount` on all data tables
+
+### Color Independence
+
+Status badges must never rely on color alone:
+
+| Status | Color | Icon | Text label |
+|---|---|---|---|
+| AVAILABLE | Green | ✓ | "Available" |
+| LOW | Orange | ⚠ | "Low Stock" |
+| RECALLED | Red | ⛔ | "Recalled" |
+| EXHAUSTED | Gray | — | "Exhausted" |
+
+Quota progress bar additionally shows numeric percentage text alongside color change.
+
+### Contrast Ratios
+
+| Foreground | Background | Ratio | AA pass |
+|---|---|---|---|
+| `#FFFFFF` | `#2D5016` | 9.1:1 | ✅ |
+| `#1A1A1A` | `#F5F5F5` | 16.0:1 | ✅ |
+| `#1A1A1A` | `#FFFFFF` | 19.0:1 | ✅ |
+| `#FFFFFF` | `#D32F2F` | 5.1:1 | ✅ |
+| `#FFFFFF` | `#FF6B35` | 3.1:1 | ⚠ verify at large text only |

+### Module Dependencies
+
+```
+cannamanage-domain    (no deps on other modules)
+       ↑
+cannamanage-service  (depends on domain)
+       ↑
+cannamanage-api      (depends on service, domain)
+cannamanage-web      (depends on service, domain)
+cannamanage-report   (depends on service, domain)
+```
+
+`cannamanage-api` and `cannamanage-web` are siblings — they do not depend on each other. The web module is the PrimeFaces JSF frontend (MVP); the API module provides the REST layer (future mobile / integration use).
+
+---
+
+## 2. Java Coding Standards
+
+### Language Version
+
+Java 21. All modern language features are permitted and preferred:
+
+| Feature | Use Case | Example |
+|---|---|---|
+| Records | DTOs, value objects, query results | `record MemberSummary(UUID id, String name, BigDecimal quotaUsed)` |
+| Sealed classes | Result types, compliance outcomes | `sealed interface QuotaResult permits QuotaOk, QuotaWarning, QuotaExceeded` |
+| Text blocks | JPQL, SQL in tests, JSON fixtures | `String jpql = """ SELECT m FROM Member m WHERE... """` |
+| Pattern matching `instanceof` | Type checks in services | `if (result instanceof QuotaExceeded e) { ... }` |
+| Switch expressions | Status mapping, report routing | `yield` syntax preferred |
+
+### Package Structure
+
+Pattern: `de.cannamanage.[module].[layer]`
+
+```
+de.cannamanage.domain.member          # Member entity
+de.cannamanage.domain.compliance      # ComplianceConstants, exceptions
+de.cannamanage.service.distribution   # DistributionService
+de.cannamanage.api.stock              # StockController, BatchDto
+de.cannamanage.web.admin              # DistributionFormBean
+de.cannamanage.report.monthly         # MonthlyComplianceReport
+```
+
+### Class Naming Conventions
+
+| Type | Pattern | Example |
+|---|---|---|
+| JPA Entity | `{Domain}` | `Member`, `Distribution`, `Batch` |
+| Spring Service | `{Domain}Service` | `MemberService`, `ComplianceService` |
+| Repository | `{Domain}Repository` | `DistributionRepository` |
+| REST Controller | `{Domain}Controller` | `StockController` |
+| JSF Backing Bean | `{Screen}Bean` | `DistributionFormBean`, `AdminDashboardBean` |
+| DTO (request) | `{Domain}Request` | `CreateDistributionRequest` |
+| DTO (response) | `{Domain}Response` / `{Domain}Dto` | `MemberSummaryDto` |
+| Exception | `{Condition}Exception` | `QuotaExceededException`, `BatchRecalledException` |
+| Enum | `{Domain}Status` / `{Domain}Type` | `BatchStatus`, `MembershipType` |
+| Constants class | `{Domain}Constants` | `ComplianceConstants` |
+
+### Dependency Injection
+
+**Constructor injection only.** Field injection (`@Autowired` on fields) is prohibited.
+
+```java
+// ✅ Correct
+@Service
+@RequiredArgsConstructor
+public class DistributionService {
+
+    private final DistributionRepository distributionRepository;
+    private final ComplianceService complianceService;
+    private final MemberRepository memberRepository;
+}
+
+// ❌ Prohibited
+@Service
+public class DistributionService {
+
+    @Autowired
+    private DistributionRepository distributionRepository;
+}
+```
+
+Lombok `@RequiredArgsConstructor` is the preferred way to generate the constructor.
+
+### Entity Base Class
+
+All `@Entity` classes must extend `AbstractTenantEntity`. No raw entities without tenant isolation.
+
+```java
+// de.cannamanage.domain.common.AbstractTenantEntity
+@MappedSuperclass
+@EntityListeners(AuditingEntityListener.class)
+public abstract class AbstractTenantEntity {
+
+    @Id
+    @GeneratedValue(strategy = GenerationType.UUID)
+    private UUID id;
+
+    @Column(name = "tenant_id", nullable = false, updatable = false)
+    private UUID tenantId;
+
+    @CreatedDate
+    @Column(name = "created_at", nullable = false, updatable = false)
+    private Instant createdAt;
+
+    @LastModifiedDate
+    @Column(name = "updated_at", nullable = false)
+    private Instant updatedAt;
+}
+
+// ✅ All entities extend this
+@Entity
+@Table(name = "members")
+@Getter
+@Builder
+@NoArgsConstructor
+@AllArgsConstructor
+public class Member extends AbstractTenantEntity {
+    // domain fields only — no id/tenantId/audit fields here
+}
+```
+
+### Transaction Boundaries
+
+- `@Transactional` belongs on **service layer** methods only
+- Controllers and repositories must not declare `@Transactional`
+- Use `@Transactional(readOnly = true)` for query-only methods — improves performance with Hibernate's read-only session optimization
+
+```java
+// ✅ Service layer — correct
+@Service
+@RequiredArgsConstructor
+public class MemberService {
+
+    @Transactional(readOnly = true)
+    public MemberSummaryDto getById(UUID memberId, UUID tenantId) { ... }
+
+    @Transactional
+    public void updateMemberStatus(UUID memberId, MemberStatus status, UUID tenantId) { ... }
+}
+
+// ❌ Controller — prohibited
+@RestController
+public class MemberController {
+
+    @Transactional  // Never here
+    @GetMapping("/members/{id}")
+    public MemberSummaryDto getMember(@PathVariable UUID id) { ... }
+}
+```
+
+### Lombok Usage
+
+| Annotation | Allowed | Notes |
+|---|---|---|
+| `@Getter` | ✅ | On entities and DTOs |
+| `@Setter` | ✅ | Use sparingly on entities; prefer builder pattern |
+| `@Builder` | ✅ | On entities and DTOs |
+| `@RequiredArgsConstructor` | ✅ | Services, beans (for DI) |
+| `@NoArgsConstructor` | ✅ | JPA requires no-arg constructor |
+| `@AllArgsConstructor` | ✅ | With `@Builder` |
+| `@ToString` | ✅ | Exclude sensitive fields: `@ToString.Exclude` on `passwordHash` etc. |
+| `@EqualsAndHashCode` | ✅ | Entities: only on `id` field |
+| `@Data` | ❌ | **Prohibited on entities** — generates mutable setters for all fields, breaks JPA proxy patterns |
+| `@SneakyThrows` | ❌ | Never hide checked exceptions |
+
+### Code Style
+
+- **Checkstyle config:** Google Java Style Guide (`checkstyle-google.xml` in parent POM)
+- **Indentation:** 4 spaces (no tabs)
+- **Line length:** 120 characters max
+- **No magic numbers** — use named constants or enums:
+
+```java
+// ❌ Magic number
+if (member.getAge() < 21) { limit = 30; }
+
+// ✅ Named constant
+if (member.getAge() < ComplianceConstants.AGE_LIMIT_UNDER21) {
+    limit = ComplianceConstants.MONTHLY_LIMIT_UNDER21_GRAMS;
+}
+```
+
+---
+
+## 3. Compliance Code Rules
+
+These rules apply exclusively to code that enforces CanG (Cannabisgesetz) distribution limits. Violations here carry legal risk.
+
+### Compliance Constants
+
+All legal limits live in a single, centrally tested constants class. **Never hardcode these values inline.**
+
+```java
+// de.cannamanage.domain.compliance.ComplianceConstants
+public final class ComplianceConstants {
+
+    private ComplianceConstants() {} // no instantiation
+
+    /** Maximum grams per single distribution for any member. */
+    public static final BigDecimal DAILY_LIMIT_GRAMS = new BigDecimal("25.0");
+
+    /** Monthly gram limit for adult members (age ≥ 21). */
+    public static final BigDecimal MONTHLY_LIMIT_ADULT_GRAMS = new BigDecimal("50.0");
+
+    /** Monthly gram limit for members under 21 years of age (CanG §10 Abs.1). */
+    public static final BigDecimal MONTHLY_LIMIT_UNDER21_GRAMS = new BigDecimal("30.0");
+
+    /** Age threshold below which the reduced monthly limit applies. */
+    public static final int AGE_LIMIT_UNDER21 = 21;
+
+    /** Minimum age for club membership (CanG §15 Abs.1). */
+    public static final int MINIMUM_MEMBER_AGE = 18;
+}
+```
+
+### ComplianceService Rules
+
+1. `ComplianceService` methods **must always execute within a `@Transactional` boundary** — either by being called from a service method already in a transaction, or by declaring `@Transactional` themselves. The compliance check and the distribution record creation must be atomic.
+
+2. Every public method in `ComplianceService` must have a corresponding test in `ComplianceServiceTest` that exercises its boundary conditions.
+
+3. `ComplianceService` is the **only** class permitted to read `ComplianceConstants` limits and make pass/fail decisions. No other class performs limit arithmetic.
+
+```java
+@Service
+@RequiredArgsConstructor
+public class ComplianceService {
+
+    private final DistributionRepository distributionRepository;
+
+    /**
+     * Validates whether a distribution of the given weight is permitted for the member.
+     *
+     * <p>Checks the daily single-distribution limit and the member's monthly quota.
+     * Must be called inside an existing @Transactional boundary — the calling
+     * DistributionService is responsible for the transaction.
+     *
+     * @param memberId   the member receiving the distribution
+     * @param tenantId   the club's tenant identifier
+     * @param weightGrams the proposed distribution weight in grams
+     * @return QuotaOk if permitted; QuotaWarning if >80% used; QuotaExceeded if over limit
+     * @throws IllegalArgumentException if weightGrams exceeds DAILY_LIMIT_GRAMS
+     */
+    public QuotaResult checkDistributionAllowed(UUID memberId, UUID tenantId, BigDecimal weightGrams) {
+        if (weightGrams.compareTo(ComplianceConstants.DAILY_LIMIT_GRAMS) > 0) {
+            throw new IllegalArgumentException(
+                "Single distribution exceeds daily limit of " + ComplianceConstants.DAILY_LIMIT_GRAMS + "g");
+        }
+        // ... monthly quota logic using ComplianceConstants
+    }
+}
+```
+
+### Distribution Record Immutability
+
+Once written, a `Distribution` record may never be modified (legal audit trail requirement). Enforce this at the JPA level:
+
+```java
+@Entity
+@Table(name = "distributions")
+@Getter
+@Builder
+@NoArgsConstructor
+@AllArgsConstructor
+public class Distribution extends AbstractTenantEntity {
+
+    @Column(name = "member_id", nullable = false, updatable = false)
+    private UUID memberId;
+
+    @Column(name = "batch_id", nullable = false, updatable = false)
+    private UUID batchId;
+
+    @Column(name = "weight_grams", nullable = false, updatable = false,
+            precision = 8, scale = 2)
+    private BigDecimal weightGrams;
+
+    @Column(name = "distributed_at", nullable = false, updatable = false)
+    private Instant distributedAt;
+
+    @Column(name = "recorded_by_admin_id", nullable = false, updatable = false)
+    private UUID recordedByAdminId;
+
+    // No setters — @Getter only, no @Setter
+    // updatable = false on ALL columns — Hibernate will reject any UPDATE attempt
+}
+```
+
+### Compliance Test Coverage Requirement
+
+`ComplianceServiceTest` must include at minimum:
+
+| Test Method | What It Covers |
+|---|---|
+| `checkDistributionAllowed_givenWeightAt25g_shouldReturnQuotaOk` | Exactly at daily limit |
+| `checkDistributionAllowed_givenWeightOver25g_shouldThrowIllegalArgument` | Daily limit exceeded |
+| `checkDistributionAllowed_givenMemberAtMonthlyLimit_shouldReturnQuotaExceeded` | Adult at 50g |
+| `checkDistributionAllowed_givenUnder21MemberAt30g_shouldReturnQuotaExceeded` | Under-21 at 30g |
+| `checkDistributionAllowed_givenUnder21MemberAtAdultLimit_shouldReturnQuotaExceeded` | Under-21 must not reach 50g |
+| `checkDistributionAllowed_givenMemberAt80Percent_shouldReturnQuotaWarning` | Warning threshold |
+| `checkDistributionAllowed_givenMemberAt40g_shouldReturnQuotaOk` | Normal adult, within limit |
+

+feat(compliance): add daily 25g distribution limit check
+
+Implements CanG §10 Abs.1 single-distribution cap. ComplianceService
+now throws IllegalArgumentException before any quota calculation if
+weightGrams > ComplianceConstants.DAILY_LIMIT_GRAMS.
+
+fix(member): correct under-21 flag when age is exactly 21
+
+Age comparison was using < instead of <=. Members who turn 21 on the
+exact distribution date now correctly receive the adult (50g) limit.
+Closes #17
+
+test(distribution): add quota boundary tests for 30g under-21 limit
+
+Adds 6 parameterized test cases covering 28g, 29g, 29.9g, 30g, 30.1g,
+and 31g for under-21 members. All reference ComplianceConstants — no
+hardcoded values in test assertions.
+
+chore(deps): update Spring Boot to 3.3.1
+
+CVE-2024-38821 fix included. No API changes required.

+### Framework Stack
+
+| Layer | Framework | Annotation / Config |
+|---|---|---|
+| Unit tests | JUnit 5 + Mockito | `@ExtendWith(MockitoExtension.class)` |
+| Integration tests | Spring Boot Test + Testcontainers | `@SpringBootTest`, `@Testcontainers` |

+
+### Test Naming Convention
+
+```
+methodName_givenCondition_shouldExpectedBehavior
+```
+
+```java
+// ✅ Correct
+@Test
+void checkDistributionAllowed_givenMemberAtMonthlyLimit_shouldThrowQuotaExceededException()
+
+@Test
+void createDistribution_givenValidRequest_shouldPersistAndReturnDto()
+
+@Test
+void getQuotaRemaining_givenUnder21Member_shouldCapAt30g()
+
+@Test
+void generateMonthlyReport_givenNoPriorDistributions_shouldReturnZeroTotals()
+```
+
+### Unit Test Structure
+
+```java
+@ExtendWith(MockitoExtension.class)
+class ComplianceServiceTest {
+
+    @Mock
+    private DistributionRepository distributionRepository;
+
+    @InjectMocks
+    private ComplianceService complianceService;
+
+    @Test
+    void checkDistributionAllowed_givenMemberAtMonthlyLimit_shouldReturnQuotaExceeded() {
+        // GIVEN
+        UUID memberId = UUID.randomUUID();
+        UUID tenantId = UUID.randomUUID();
+        BigDecimal currentMonthTotal = ComplianceConstants.MONTHLY_LIMIT_ADULT_GRAMS;
+
+        when(distributionRepository.sumWeightByMemberAndMonth(eq(memberId), eq(tenantId), any()))
+            .thenReturn(currentMonthTotal);
+
+        // WHEN
+        QuotaResult result = complianceService.checkDistributionAllowed(
+            memberId, tenantId, new BigDecimal("1.0"));
+
+        // THEN
+        assertThat(result).isInstanceOf(QuotaExceeded.class);
+    }
+}
+```
+
+### Integration Test Structure
+
+```java
+@SpringBootTest
+@Testcontainers
+@Transactional  // rolls back after each test
+class DistributionServiceIntegrationTest {
+
+    @Container
+    static PostgreSQLContainer<?> postgres = new PostgreSQLContainer<>("postgres:16-alpine");
+
+    @DynamicPropertySource
+    static void configureDataSource(DynamicPropertyRegistry registry) {
+        registry.add("spring.datasource.url", postgres::getJdbcUrl);
+        registry.add("spring.datasource.username", postgres::getUsername);
+        registry.add("spring.datasource.password", postgres::getPassword);
+    }
+
+    // Tests run against real PostgreSQL — Flyway migrations apply automatically
+}
+```
+
+### Coverage Target
+
+| Module | Line Coverage Target |
+|---|---|
+| `cannamanage-service` | **≥ 80%** (enforced by JaCoCo in CI) |
+| `cannamanage-domain` | ≥ 70% (entities + value objects) |
+| `cannamanage-api` | ≥ 70% (controllers via MockMvc) |
+| `cannamanage-report` | ≥ 60% (PDF generation harder to test) |
+| `cannamanage-web` | Best effort (JSF backing beans — limited testability) |
+
+### Test Rules
+
+1. **No test may hardcode a compliance limit value.** All assertions must reference `ComplianceConstants`:
+
+```java
+// ❌ Prohibited
+assertThat(limit).isEqualTo(new BigDecimal("50.0"));
+
+// ✅ Required
+assertThat(limit).isEqualTo(ComplianceConstants.MONTHLY_LIMIT_ADULT_GRAMS);
+```
+
+2. Parameterized tests (`@ParameterizedTest`) are strongly preferred for boundary condition coverage.
+
+3. Test data builders (or fixtures) must live in `src/test/java/.../fixtures/` — no anonymous object creation scattered across test methods.
+
+---
+
+## 6. Code Review Checklist
+
+Since CannaManage is a solo development project, a self-review checklist replaces a peer review process. All items must be checked before merging any PR to `main`.
+
+### Self-Review Checklist
+
+```markdown
+## Compliance & Legal
+- [ ] All distribution limits reference `ComplianceConstants` — zero hardcoded values
+- [ ] `Distribution` entity fields are annotated `@Column(updatable = false)` where required
+- [ ] `ComplianceService` calls are only made inside `@Transactional` boundaries
+- [ ] New compliance rules have corresponding unit tests in `ComplianceServiceTest`
+
+## Data & Multi-Tenancy
+- [ ] New entity extends `AbstractTenantEntity`
+- [ ] `tenant_id` is never accepted from user input (HTTP body, query param, path variable)
+- [ ] All repository queries filter by `tenantId` — no cross-tenant data leakage possible
+
+## Security & DSGVO
+- [ ] No PII in log statements (no email, full name, member number in log lines)
+- [ ] No passwords, tokens, or secrets hardcoded anywhere
+- [ ] New REST endpoints annotated with `@PreAuthorize`
+- [ ] DTOs validated with Bean Validation annotations (`@NotNull`, `@Size`, etc.)
+
+## Database
+- [ ] Flyway migration file added for any schema change (`V{n}__description.sql`)
+- [ ] Migration file is backward-compatible or includes rollback notes
+- [ ] No `@Column(nullable = false)` added without corresponding DB migration
+
+## Code Quality
+- [ ] Constructor injection used — no `@Autowired` field injection
+- [ ] No `@Data` on JPA entities
+- [ ] No magic numbers — named constants or enums used
+- [ ] Checkstyle passes locally (`./mvnw checkstyle:check`)
+- [ ] Javadoc on all public service methods
+
+## Testing
+- [ ] Unit test added for new service method
+- [ ] Integration test updated if schema or contract changed
+- [ ] Test coverage does not decrease in `cannamanage-service`
+- [ ] Test method names follow `method_givenCondition_shouldExpect` pattern
+
+## General
+- [ ] Commit message follows Conventional Commits format
+- [ ] Branch name follows `feature/US-XXX-` or `fix/` convention
+- [ ] No `TODO` comments left in production code (use GitHub Issues instead)
+```
+

+
+## 7. Security Standards
+
+### Authentication & Authorization
+
+```java
+// JWT secret from environment only — never in application.properties
+@Value("${JWT_SECRET}")
+private String jwtSecret;
+
+// All endpoints behind @PreAuthorize — no security by obscurity
+@RestController
+@RequestMapping("/api/v1/distributions")
+public class DistributionController {
+
+    @GetMapping
+    @PreAuthorize("hasRole('ADMIN')")
+    public Page<DistributionDto> list(...) { ... }
+
+    @PostMapping
+    @PreAuthorize("hasRole('ADMIN')")
+    public DistributionDto create(...) { ... }
+}
+
+// Member portal endpoints restricted to role + own data
+@GetMapping("/api/v1/member/quota")
+@PreAuthorize("hasRole('MEMBER') and #memberId == authentication.principal.memberId")
+public QuotaDto getQuota(@RequestParam UUID memberId) { ... }
+```
+
+### CORS Configuration
+
+```java
+@Bean
+CorsConfigurationSource corsConfigurationSource() {
+    CorsConfiguration config = new CorsConfiguration();
+    // No wildcard — club subdomain only
+    config.setAllowedOriginPatterns(List.of("https://*.cannamanage.de"));
+    config.setAllowedMethods(List.of("GET", "POST", "PUT", "DELETE", "OPTIONS"));
+    config.setAllowedHeaders(List.of("Authorization", "Content-Type"));
+    config.setAllowCredentials(true);
+    // ...
+}
+```
+
+### Input Validation
+
+All DTOs must be annotated with Bean Validation constraints. The controller calls `@Valid` on request bodies.
+
+```java
+public record CreateDistributionRequest(
+
+    @NotNull(message = "Member ID is required")
+    UUID memberId,
+
+    @NotNull(message = "Batch ID is required")
+    UUID batchId,
+
+    @NotNull(message = "Weight is required")
+    @DecimalMin(value = "0.1", message = "Weight must be at least 0.1g")
+    @DecimalMax(value = "25.0", message = "Weight cannot exceed daily limit")
+    BigDecimal weightGrams
+) {}
+```
+
+### SQL Injection Prevention
+
+- **JPA named queries only** — no string concatenation in JPQL
+- Spring Data JPA repository methods generate parameterized queries automatically
+- Native SQL queries use `@Query` with named parameters (`:param` syntax), never `+`
+
+```java
+// ✅ Safe — parameterized
+@Query("SELECT SUM(d.weightGrams) FROM Distribution d WHERE d.memberId = :memberId AND d.tenantId = :tenantId AND MONTH(d.distributedAt) = :month")
+BigDecimal sumWeightByMemberAndMonth(@Param("memberId") UUID memberId,
+                                     @Param("tenantId") UUID tenantId,
+                                     @Param("month") int month);
+
+// ❌ Prohibited — SQL injection risk
+String jpql = "SELECT ... WHERE name = '" + memberName + "'";
+```
+
+### Password Hashing
+
+```java
+@Bean
+PasswordEncoder passwordEncoder() {
+    return new BCryptPasswordEncoder(12);  // strength 12 — ~250ms per hash on modern hardware
+}
+```
+
+### Sensitive Data Logging
+
+```java
+// ❌ Never log PII
+log.info("Processing distribution for member: {}", member.getEmail());
+log.info("Member {} requested quota", member.getFullName());
+
+// ✅ Log with opaque identifiers only
+log.info("Processing distribution for memberId={} tenantId={}", member.getId(), tenantId);
+log.info("Quota check passed for memberId={}", memberId);
+```
+
+---
+
+## 8. Environment Configuration
+
+### Environment Variables Reference
+
+All secrets and environment-specific configuration are provided via environment variables. Never commit secrets to version control.
+
+| Variable | Required | Default | Description |
+|---|---|---|---|
+| `DB_URL` | ✅ | — | JDBC URL, e.g. `jdbc:postgresql://localhost:5432/cannamanage` |
+| `DB_USERNAME` | ✅ | — | PostgreSQL username |
+| `DB_PASSWORD` | ✅ | — | PostgreSQL password |
+| `JWT_SECRET` | ✅ | — | 256-bit (32-byte) random secret for JWT signing; generate with `openssl rand -base64 32` |
+| `JWT_ACCESS_TTL_HOURS` | ❌ | `8` | Access token TTL in hours |
+| `JWT_REFRESH_TTL_DAYS` | ❌ | `30` | Refresh token TTL in days |
+| `STRIPE_SECRET_KEY` | ✅ (billing) | — | Stripe secret key (starts with `sk_live_` in production) |
+| `STRIPE_WEBHOOK_SECRET` | ✅ (billing) | — | Stripe webhook signing secret for subscription events |
+| `MAIL_HOST` | ✅ | — | SMTP host for transactional emails |
+| `MAIL_USERNAME` | ✅ | — | SMTP username |
+| `MAIL_PASSWORD` | ✅ | — | SMTP password |
+| `MAIL_FROM` | ❌ | `noreply@cannamanage.de` | From address for system emails |
+| `SENTRY_DSN` | ❌ | — | Sentry DSN for error tracking; omit to disable |
+| `APP_BASE_URL` | ✅ | — | Application base URL, e.g. `https://meinclub.cannamanage.de` |
+| `ADMIN_INITIAL_EMAIL` | ❌ | — | Seed admin email on first startup (Flyway data migration) |
+| `ADMIN_INITIAL_PASSWORD` | ❌ | — | Seed admin password — change immediately after first login |
+
+### `application.properties` Pattern
+
+```properties
+# application.properties — references env vars only; no values hardcoded
+
+spring.datasource.url=${DB_URL}
+spring.datasource.username=${DB_USERNAME}
+spring.datasource.password=${DB_PASSWORD}
+
+spring.jpa.hibernate.ddl-auto=validate
+spring.flyway.enabled=true
+spring.flyway.locations=classpath:db/migration
+
+jwt.secret=${JWT_SECRET}
+jwt.access.ttl-hours=${JWT_ACCESS_TTL_HOURS:8}
+jwt.refresh.ttl-days=${JWT_REFRESH_TTL_DAYS:30}
+
+stripe.secret-key=${STRIPE_SECRET_KEY}
+stripe.webhook-secret=${STRIPE_WEBHOOK_SECRET}
+
+spring.mail.host=${MAIL_HOST}
+spring.mail.username=${MAIL_USERNAME}
+spring.mail.password=${MAIL_PASSWORD}
+
+sentry.dsn=${SENTRY_DSN:}
+```
+
+### Profile Strategy
+
+> **`spring.profiles.active=prod` is NOT a security mechanism.** Never use profile-based condition checks to gate security-relevant behavior (e.g., `@ConditionalOnProperty(name="spring.profiles.active", havingValue="prod")`).
+
+Profiles are used **only** for infrastructure wiring (in-memory H2 vs. real PostgreSQL for tests, Testcontainers vs. external DB).
+
+| Profile | Usage |
+|---|---|
+| `(none)` | Production — all config from environment variables |
+| `test` | JUnit integration tests — Testcontainers PostgreSQL |
+| `dev` | Local development — Docker Compose PostgreSQL, verbose SQL logging |
+
+### Local Development Setup
+
+```bash
+# Start local PostgreSQL via Docker Compose
+docker compose up -d postgres
+
+# Run with dev profile (verbose SQL, local DB)
+./mvnw spring-boot:run -Dspring-boot.run.profiles=dev \
+  -Dspring-boot.run.arguments="--DB_URL=jdbc:postgresql://localhost:5432/cannamanage_dev \
+    --DB_USERNAME=cannamanage --DB_PASSWORD=dev_password \
+    --JWT_SECRET=$(openssl rand -base64 32)"
+```

+
+### 1.3 CI Trigger Policy
+
+| Branch pattern | Tests run |
+|---------------|-----------|
+| `feature/*` | Unit tests only (`./mvnw test`) |
+| `develop` | Unit + Integration (`./mvnw verify -P integration-tests`) |

+
+---
+
+**TC-002** | `checkDistributionAllowed_givenUnder21AtMonthlyLimit_shouldThrowQuotaExceededMonthly`
+- **Given:** Under-21 member (age 18) with exactly 30.0g distributed this calendar month, requesting 1.0g more

+
+---
+
+**TC-003** | `checkDistributionAllowed_givenAdultAtDailyLimit_shouldThrowQuotaExceededDaily`
+- **Given:** Adult member with exactly 25.0g distributed today, requesting 0.5g more
+- **When:** `complianceService.checkDistributionAllowed(memberId, 0.5)`

+- **Compliance ref:** CanG §19(4) — under-21 members restricted to ≤10% THC strains
+
+---
+
+**TC-005** | `checkDistributionAllowed_givenAdultAt49gMonthlyRequesting2g_shouldThrowQuotaExceededMonthly`
+- **Given:** Adult member with 49.0g distributed this month, requesting 2.0g (would total 51.0g)
+- **When:** `complianceService.checkDistributionAllowed(memberId, 2.0)`
+- **Then:** Throws `QuotaExceededException` with code `QUOTA_EXCEEDED_MONTHLY`
+- **Note:** Even partial over-quota requests must be rejected in full; no partial fulfillment
+
+---
+
+**TC-006** | `checkDistributionAllowed_givenAdultAt0gRequesting25g_shouldReturnAllowed`
+- **Given:** Adult member with 0.0g distributed this month and today, requesting 25.0g
+- **When:** `complianceService.checkDistributionAllowed(memberId, 25.0)`
+- **Then:** Returns `DistributionAllowedResult` with `allowed = true`, `remainingDaily = 0.0`, `remainingMonthly = 25.0`
+- **Note:** Exactly at daily limit — allowed
+
+---
+
+**TC-007** | `checkDistributionAllowed_givenAdultAt24_9gDailyRequesting0_1g_shouldReturnAllowed`
+- **Given:** Adult member with 24.9g distributed today, requesting 0.1g (would reach exactly 25.0g)
+- **When:** `complianceService.checkDistributionAllowed(memberId, 0.1)`

+
+---
+
+**TC-010** | `checkDistributionAllowed_givenExpelledMember_shouldThrowMemberInactive`
+- **Given:** Member with `status = MemberStatus.EXPELLED`, requesting any amount
+- **When:** `complianceService.checkDistributionAllowed(memberId, 5.0)`
+- **Then:** Throws `QuotaExceededException` with code `MEMBER_INACTIVE`

+
+---
+
+## 3. Unit Test Cases — MemberService
+
+**Class under test:** `de.cannamanage.service.MemberService`  
+**Dependencies mocked:** `MemberRepository`, `ClubRepository`, `PasswordEncoder`
+
+---
+
+**TC-011** | `createMember_givenAge17_shouldThrowUnderageException`
+- **Given:** `CreateMemberRequest` with DOB resulting in age 17 at time of registration
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Throws `UnderageException` with message containing minimum age (18)
+- **Compliance ref:** CanG §6(1) — membership requires minimum age 18
+
+---
+
+**TC-012** | ~~`createMember_givenAge18_shouldSucceedAndSetIsUnder21False`~~ — *this case is incorrect*
+
+> **Note:** Age 18 IS under 21, therefore `isUnder21 = true`. See TC-013.
+
+---
+
+**TC-013** | `createMember_givenAge18_shouldSucceedAndSetIsUnder21True`
+- **Given:** `CreateMemberRequest` with DOB resulting in age 18 at time of registration
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Returns created `Member` with `isUnder21 = true`, `status = ACTIVE`
+- **Note:** The 18-year-old flag matters for quota enforcement (30g/month, ≤10% THC)
+
+---
+
+**TC-014** | `createMember_givenAge21_shouldSucceedAndSetIsUnder21False`
+- **Given:** `CreateMemberRequest` with DOB resulting in age exactly 21 at time of registration
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Returns created `Member` with `isUnder21 = false`, `status = ACTIVE`
+- **Note:** Age 21 is the boundary — exactly 21 qualifies as adult for quota purposes
+
+---
+
+**TC-015** | `createMember_givenDuplicateEmail_shouldThrowDuplicateMemberException`
+- **Given:** `MemberRepository.existsByEmailAndTenantId(email, tenantId)` returns `true`
+- **When:** `memberService.createMember(request, tenantId)`
+- **Then:** Throws `DuplicateMemberException` with code `DUPLICATE_EMAIL`
+- **Note:** Email uniqueness is per-tenant, not global
+
+---
+
+## 4. Unit Test Cases — Tenant Isolation
+
+**Class under test:** JPA repositories with `@TenantAware` filter active  
+**Setup:** Thread-local `TenantContext` populated via `TenantContextHolder.setTenantId()`
+
+---
+
+**TC-016** | `distributionRepository_givenTenantAContext_shouldNotReturnTenantBData`
+- **Given:** Two tenants (Tenant A: UUID-A, Tenant B: UUID-B); 5 distributions for each; `TenantContextHolder` set to UUID-A
+- **When:** `distributionRepository.findAll()`
+- **Then:** Returns exactly 5 records, all with `tenantId = UUID-A`; zero records from Tenant B
+- **Note:** Hibernate filter `tenantFilter` must be enabled in `TenantAwareInterceptor`
+
+---
+
+**TC-017** | `memberRepository_givenTenantAContext_shouldNotSeeClubBMembers`
+- **Given:** 10 members in Club A, 8 members in Club B; context set to Club A's tenant
+- **When:** `memberRepository.findAll()`
+- **Then:** Returns exactly 10 records; no member from Club B present
+- **Note:** Cross-tenant data leakage is a GDPR violation, not just a business bug
+
+---
+
+## 5. Integration Test Cases (Testcontainers)
+
+**Setup:** `@SpringBootTest(webEnvironment = RANDOM_PORT)` with `@Testcontainers`; real PostgreSQL 16 container; Flyway migrations applied before each test class.
+
+---
+
+**TC-018** | `POST /api/v1/distributions — successful distribution recording`
+- **Given:** Active adult member with 0g distributed; valid `DistributionRequest` for 10.0g; authenticated as `ROLE_ADMIN`
+- **When:** `POST /api/v1/distributions` with valid JWT
+- **Then:** HTTP 201; response body contains `distributionId`, `amount = 10.0`, `recordedAt`; DB contains one `distribution` row with `is_recalled = false`
+
+---
+
+**TC-019** | `POST /api/v1/distributions — quota exceeded returns 422`
+- **Given:** Adult member with 50.0g already distributed this month; requesting 1.0g more
+- **When:** `POST /api/v1/distributions`
+- **Then:** HTTP 422; response body `{"errorCode": "QUOTA_EXCEEDED_MONTHLY", "remainingMonthly": 0.0}`
+
+---
+
+**TC-020** | `POST /api/v1/distributions — concurrent race condition (last gram)`
+- **Given:** Adult member with 24.9g distributed today; two concurrent requests each for 0.2g (both would individually exceed 25g/day)
+- **When:** Both requests fired simultaneously via two threads
+- **Then:** Exactly one succeeds (HTTP 201); exactly one fails (HTTP 422 `QUOTA_EXCEEDED_DAILY`); DB total does not exceed 25.0g
+- **Mechanism:** `SELECT ... FOR UPDATE` on quota aggregation query prevents double-spend
+
+---
+
+**TC-021** | `POST /api/v1/auth/login — valid credentials return JWT`
+- **Given:** Admin user with email `admin@test-club.de`, correct password
+- **When:** `POST /api/v1/auth/login` with `{"email": "admin@test-club.de", "password": "..."}`
+- **Then:** HTTP 200; response contains `accessToken` (JWT), `tokenType = "Bearer"`, `expiresIn = 3600`
+
+---
+
+**TC-022** | `POST /api/v1/auth/login — invalid credentials return 401`
+- **Given:** Admin user exists; wrong password provided
+- **When:** `POST /api/v1/auth/login` with wrong password
+- **Then:** HTTP 401; response `{"errorCode": "INVALID_CREDENTIALS"}`; no token issued
+
+---
+
+**TC-023** | `GET /api/v1/members — ROLE_MEMBER accessing admin endpoint returns 403`
+- **Given:** Authenticated user with `ROLE_MEMBER` JWT (not ROLE_ADMIN)
+- **When:** `GET /api/v1/members` (admin-only endpoint)
+- **Then:** HTTP 403; response `{"errorCode": "FORBIDDEN"}`
+
+---
+
+**TC-024** | `GET /api/v1/members/{id}/quota — member accessing own quota returns 200`
+- **Given:** Authenticated member with JWT; requesting their own `memberId`
+- **When:** `GET /api/v1/members/{ownId}/quota`
+- **Then:** HTTP 200; response contains `dailyUsed`, `dailyRemaining`, `monthlyUsed`, `monthlyRemaining`, `isUnder21`
+
+---
+
+**TC-025** | `GET /api/v1/members/{otherMemberId}/quota — member accessing other member returns 403`
+- **Given:** Authenticated member requesting quota of a *different* member (same club)
+- **When:** `GET /api/v1/members/{otherMemberId}/quota`
+- **Then:** HTTP 403; GDPR principle: members must not see each other's consumption data
+
+---
+
+**TC-026** | `POST /api/v1/stock/batches/{id}/recall — verify cascade`
+- **Given:** Batch `BATCH-TEST-001` with 3 distributions recorded against it; `isRecalled = false`
+- **When:** `POST /api/v1/stock/batches/BATCH-TEST-001/recall` with `{"reason": "Contamination detected"}`
+- **Then:** HTTP 200; batch `isRecalled = true`; all 3 distribution records have `isRecalled = true`; response body contains list of 3 affected member IDs for notification
+
+---
+
+## 6. Test Data Fixtures
+
+Define these constants in `src/test/java/de/cannamanage/fixtures/TestFixtures.java`:

+    public static final double UNDER21_MAX_THC_PERCENT = 10.0;
+}
+```

+
+## 7. Coverage Requirements
+
+| Module | Test Type | Minimum Coverage | Enforcement |
+|--------|-----------|-----------------|-------------|
+| `cannamanage-service` | Unit | 80% line | JaCoCo CI gate |
+| `cannamanage-api` | Integration | 70% endpoint coverage | Manual checklist |
+| `cannamanage-domain` | Unit | 60% line (entities/enums) | JaCoCo CI gate |
+| `ComplianceService` | Unit | **100% line + branch** | JaCoCo CI gate — hard fail |
+| `TenantIsolationFilter` | Unit + Integration | 90% line | JaCoCo CI gate |
+
+> **Rationale for 100% on ComplianceService:** Each uncovered line is a potential legal violation. A missed branch in quota calculation could result in over-distribution — a criminal offence under CanG §34. This is not negotiable.

+
+```bash
+# Run all unit tests
+./mvnw test -pl cannamanage-service
+
+# Run integration tests (requires Docker for Testcontainers)
+./mvnw verify -P integration-tests
+
+# Run specific test class
+./mvnw test -pl cannamanage-service -Dtest=ComplianceServiceTest

+# Run compliance tests only (tagged)
+./mvnw test -pl cannamanage-service -Dgroups=compliance
+
+# Check coverage gate (will fail build if thresholds not met)
+./mvnw verify -P coverage-check
+```
+
+### Testcontainers Docker requirement
+
+Integration tests require Docker available on the host. The PostgreSQL container is pulled automatically by Testcontainers on first run. Ensure:
+- Docker daemon running: `systemctl start docker` (or `docker info`)
+- User in `docker` group: `sudo usermod -aG docker $USER`
+
+### Test annotation conventions

+# 09 — Deployment Guide
+
+**Project:** CannaManage — B2B SaaS for German Cannabis Social Clubs  
+**Version:** 0.1.0-PLAN  
+**Date:** 2026-04-06  
+**Target environment:** Hetzner VPS — Ubuntu 22.04 LTS — Docker Compose
+
+---
+
+## 1. Prerequisites
+
+### Hetzner VPS Specification
+
+| Resource | Value | Monthly Cost |
+|----------|-------|-------------|
+| Server type | CX21 | ~€5.88/month |
+| vCPU | 2 | — |
+| RAM | 4 GB | — |
+| SSD | 40 GB | — |
+| Network | 20 TB transfer | — |
+| OS | Ubuntu 22.04 LTS | — |
+
+> **Scale-up trigger:** Upgrade to CX31 (8GB RAM) when concurrent active clubs exceeds 20. PostgreSQL is the memory consumer — headroom is consumed by connection pools, not application heap.
+
+### DNS Setup
+
+| Record | Type | Value |
+|--------|------|-------|
+| `cannamanage.de` | A | `<VPS-IP>` |
+| `app.cannamanage.de` | A | `<VPS-IP>` |
+| `*.cannamanage.de` | A | `<VPS-IP>` |
+
+Wildcard A record enables future per-club subdomains (`clubname.cannamanage.de`) without additional DNS changes.
+
+### Required Software
+
+- Docker Engine 24+ (`docker.io` or Docker CE)
+- Docker Compose v2 (`docker compose` — not `docker-compose`)
+- Certbot with Nginx plugin (`python3-certbot-nginx`)
+- OpenSSH server (enabled by default on Ubuntu)
+
+---
+
+## 2. Infrastructure Architecture

+
+All three services run on an internal Docker bridge network (`cannamanage_net`). Only Nginx is exposed to the public internet. PostgreSQL has no external port binding.

+
+## 4. Environment Variables
+
+**File:** `/opt/cannamanage/.env` (never committed to git — add to `.gitignore`)
+
+```bash
+# Database
+DB_USERNAME=cannamanage_user
+DB_PASSWORD=<strong-random-password-min-32-chars>
+
+# JWT signing key (256-bit minimum — generate with: openssl rand -hex 32)
+JWT_SECRET=<256-bit-random-hex>
+
+# Stripe (use sk_live_ for production, sk_test_ for staging)
+STRIPE_SECRET_KEY=sk_live_...
+STRIPE_WEBHOOK_SECRET=whsec_...
+
+# Email (SMTP)
+MAIL_HOST=smtp.example.com
+MAIL_PORT=587
+MAIL_USERNAME=noreply@cannamanage.de
+MAIL_PASSWORD=<mail-password>
+MAIL_FROM=CannaManage <noreply@cannamanage.de>
+
+# Error tracking
+SENTRY_DSN=https://<key>@<org>.ingest.sentry.io/<project-id>
+
+# Application version (set by CI during deploy)
+VERSION=latest
+```
+
+> **Security:** Never store `.env` in version control. Use Gitea repository secrets for CI and inject at deploy time. On the VPS, set file permissions: `chmod 600 /opt/cannamanage/.env`.
+
+---
+
+## 5. First-Time Deployment
+
+### Step 1 — Create Hetzner VPS
+
+1. Log into [console.hetzner.cloud](https://console.hetzner.cloud)
+2. Create server: **CX21**, Ubuntu 22.04, Nuremberg or Frankfurt datacenter
+3. Add your SSH public key during setup (`cat ~/.ssh/id_ed25519.pub`)
+4. Note the assigned IPv4 address — update DNS A records
+
+### Step 2 — Install Docker + Docker Compose
+
+```bash
+ssh root@<VPS-IP>
+
+# Update system
+apt update && apt upgrade -y
+
+# Install Docker
+curl -fsSL https://get.docker.com | sh
+
+# Add deploy user (never run production as root)
+adduser deploy
+usermod -aG docker deploy
+usermod -aG sudo deploy
+
+# Install Certbot
+apt install -y python3-certbot-nginx certbot
+```
+
+### Step 3 — Clone Repository
+
+```bash
+su - deploy
+mkdir -p /opt/cannamanage
+cd /opt/cannamanage
+git clone http://192.168.188.119:30008/pplate/cannamanage.git .
+# Or from public mirror when available
+```
+
+### Step 4 — Create Production `.env`
+
+```bash
+cd /opt/cannamanage
+cp .env.example .env
+nano .env  # Fill in all production secrets
+chmod 600 .env
+```
+
+### Step 5 — Obtain SSL Certificate
+
+```bash
+# Stop anything on port 80 first (nothing should be running yet)
+certbot certonly --standalone \
+  -d app.cannamanage.de \
+  --non-interactive \
+  --agree-tos \
+  -m ssl@cannamanage.de
+
+# Symlink certs into nginx_certs volume location
+# Certbot places certs at /etc/letsencrypt/live/app.cannamanage.de/
+```
+
+### Step 6 — Build Docker Image
+
+```bash
+# On the VPS (or build locally and push to registry)
+./mvnw package -DskipTests -P production
+docker build -t cannamanage:latest .
+```
+
+### Step 7 — Start Services
+
+```bash
+cd /opt/cannamanage
+docker compose up -d
+```
+
+### Step 8 — Verify Health
+
+```bash
+# All containers should be 'healthy' or 'running'
+docker compose ps
+
+# Check application logs
+docker compose logs -f app --tail=100
+
+# Test health endpoint
+curl -f http://localhost:8080/actuator/health
+# Expected: {"status":"UP","components":{"db":{"status":"UP"},"diskSpace":{"status":"UP"}}}
+```
+
+### Step 9 — Flyway Migrations
+
+Flyway runs automatically on Spring Boot startup. Verify migration log:
+
+```bash
+docker compose logs app | grep -i flyway
+# Expected: Successfully applied N migrations to schema "public"
+```
+
+### Step 10 — Create First Admin User
+
+```bash
+# Option A: via REST API (recommended)
+curl -X POST https://app.cannamanage.de/api/v1/admin/bootstrap \
+  -H "Content-Type: application/json" \
+  -d '{
+    "adminEmail": "admin@yourclub.de",
+    "adminPassword": "<strong-password>",
+    "clubName": "Your Club e.V.",
+    "clubRegistrationNumber": "VR 12345"
+  }'
+
+# The bootstrap endpoint is disabled after first use (one-time setup flag in DB)
+```
+
+### Step 11 — Verify Production Access
+
+```bash
+# Web UI
+open https://app.cannamanage.de
+
+# API health check
+curl https://app.cannamanage.de/actuator/health
+```
+
+---
+
+## 6. CI/CD Pipeline (Gitea Actions)
+
+**File:** `.gitea/workflows/deploy.yml`

+            set -e
+            cd /opt/cannamanage
+
+            # Load new image
+            docker load < /tmp/cannamanage.tar.gz
+            rm /tmp/cannamanage.tar.gz

+
+            # Prune old images (keep last 3)
+            docker image prune -f
+          "
+```
+
+### Required Gitea Repository Secrets
+
+| Secret | Value |
+|--------|-------|
+| `HETZNER_IP` | VPS IPv4 address |
+| `SSH_PRIVATE_KEY` | Private key for `deploy` user |
+
+Add deploy user's public key to VPS authorized_keys:
+```bash
+# On VPS as deploy user
+mkdir -p ~/.ssh && chmod 700 ~/.ssh
+echo "<gitea-actions-public-key>" >> ~/.ssh/authorized_keys
+chmod 600 ~/.ssh/authorized_keys
+```
+
+---
+
+## 7. Database Backup
+
+### Automated Daily Backup
+
+Add to root crontab (`crontab -e`):
+
+```bash
+# Daily backup at 03:00 UTC — keep 14 days
+0 3 * * * docker exec cannamanage-db pg_dump \
+  -U cannamanage_user \
+  --format=custom \
+  cannamanage | gzip > /opt/backups/cannamanage_$(date +\%Y\%m\%d).sql.gz
+
+# Cleanup backups older than 14 days
+5 3 * * * find /opt/backups -name "cannamanage_*.sql.gz" -mtime +14 -delete
+```
+
+Create backup directory:
+```bash
+mkdir -p /opt/backups
+chown deploy:deploy /opt/backups
+```
+
+### Restore from Backup
+
+```bash
+# Restore (caution: this overwrites existing data)
+gunzip -c /opt/backups/cannamanage_20260406.sql.gz | \
+  docker exec -i cannamanage-db pg_restore \
+    -U cannamanage_user \
+    --clean \
+    --dbname=cannamanage
+
+# Verify restore
+docker exec cannamanage-db psql \
+  -U cannamanage_user \
+  -d cannamanage \
+  -c "SELECT COUNT(*) FROM clubs;"
+```
+
+### Offsite Backup (Optional)
+
+For additional redundancy, sync backups to Hetzner Object Storage:
+
+```bash
+# Install s3cmd and configure with Hetzner S3-compatible endpoint
+s3cmd sync /opt/backups/ s3://cannamanage-backups/
+```
+
+---
+
+## 8. Monitoring & Health Checks
+
+### Spring Boot Actuator
+
+The application exposes health endpoints via `spring-boot-actuator`:
+
+```bash
+# Full health detail (requires ROLE_ADMIN JWT)
+GET /actuator/health
+
+# Example response
+{
+  "status": "UP",
+  "components": {
+    "db": { "status": "UP", "details": { "database": "PostgreSQL", "validationQuery": "isValid()" } },
+    "diskSpace": { "status": "UP", "details": { "total": 42GB, "free": 30GB } },
+    "ping": { "status": "UP" }
+  }
+}
+```
+
+Expose only `health` and `info` publicly in `application-production.yml`:
+```yaml
+management:
+  endpoints:
+    web:
+      exposure:
+        include: health,info
+  endpoint:
+    health:
+      show-details: when-authorized
+```
+
+### Log Locations
+
+| Source | Location |
+|--------|----------|
+| Application logs | `docker compose logs -f app` |
+| Nginx access logs | `/var/log/nginx/access.log` |
+| Nginx error logs | `/var/log/nginx/error.log` |
+| PostgreSQL logs | `docker compose logs db` |
+| Sentry (errors) | `https://sentry.io/organizations/<org>/` |
+
+### Alerting
+
+Configure Sentry to email on new errors:
+1. Set `SENTRY_DSN` in `.env`
+2. Add `io.sentry:sentry-spring-boot-starter-jakarta:7.x` to POM
+3. Sentry auto-captures all unhandled exceptions with full stack trace
+
+Simple uptime check via `cron` + email:
+
+```bash
+# Health check every 5 minutes — email on 3 consecutive failures
+*/5 * * * * /opt/cannamanage/scripts/health_check.sh
+```
+
+```bash
+#!/bin/bash
+# /opt/cannamanage/scripts/health_check.sh
+HEALTH_URL="https://app.cannamanage.de/actuator/health"
+FAIL_COUNT_FILE="/tmp/cannamanage_health_fails"
+
+HTTP_STATUS=$(curl -s -o /dev/null -w "%{http_code}" "$HEALTH_URL")
+if [ "$HTTP_STATUS" != "200" ]; then
+    FAILS=$(cat "$FAIL_COUNT_FILE" 2>/dev/null || echo 0)
+    FAILS=$((FAILS + 1))
+    echo "$FAILS" > "$FAIL_COUNT_FILE"
+    if [ "$FAILS" -ge 3 ]; then
+        echo "CannaManage health check failed $FAILS times" | \
+          mail -s "ALERT: CannaManage DOWN" admin@cannamanage.de
+    fi
+else
+    echo 0 > "$FAIL_COUNT_FILE"
+fi
+```
+
+---
+
+## 9. SSL Certificate Renewal
+
+Let's Encrypt certificates expire after 90 days. Certbot handles renewal automatically:
+
+```bash
+# Test renewal (dry run — no actual renewal)
+certbot renew --dry-run
+
+# Manual renewal
+certbot renew --nginx
+
+# Reload Nginx after renewal
+docker exec cannamanage-nginx nginx -s reload
+```
+
+### Auto-Renewal via Cron
+
+```bash
+# Renew at 02:00 UTC on the 1st and 15th of each month
+0 2 1,15 * * certbot renew --quiet --nginx && \
+  docker exec cannamanage-nginx nginx -s reload
+```
+
+Certbot only renews when the certificate is less than 30 days from expiry — safe to run frequently.
+
+---
+
+## 10. Rollback Procedure
+
+If a deployment causes issues:
+
+```bash
+# On VPS — list recent images
+docker images cannamanage --format "table {{.Tag}}\t{{.CreatedAt}}"
+
+# Roll back to previous SHA
+cd /opt/cannamanage
+VERSION=<previous-sha> docker compose up -d app
+
+# Verify health after rollback
+docker compose ps app
+curl https://app.cannamanage.de/actuator/health
+```
+
+If database migrations were applied and rollback is needed:
+1. Restore from last backup (see Section 7)
+2. Redeploy the previous image version
+3. Flyway baseline the schema at previous version
+
+> **Note:** Flyway migrations are append-only and forward-only. Design migrations to be reversible where possible (add columns before removing old ones, etc.).

+# 10 — Sprint 0 Planning Retrospective
+
+**Project:** CannaManage — B2B SaaS for German Cannabis Social Clubs  
+**Sprint:** 0 — Planning & Documentation  
+**Period:** 2026-04-04 to 2026-04-06  
+**Mode:** Solo planning, AI-assisted documentation (Claude Sonnet 4.6 via Roo Orchestrator + Doc Writer modes)  
+**Outcome:** ✅ Complete — 10-document suite written, architecture locked
+
+---
+
+## What Went Well ✅
+
+**AI-assisted documentation at scale.** The complete documentation suite (10 documents, ~25,000 words total) was created in a single focused session using the Roo Orchestrator mode to coordinate multi-document generation. This would have taken 2–3 days manually. The quality is high enough to serve as actual implementation guidance — not placeholder text.
+
+**Legal analysis confirmed viability early.** The CanG compliance review (Phase 1) identified the key constraints (no public directory, no consumer-facing advertising, B2B-only) before any code was written. These became hard architectural constraints rather than late surprises. No "oh wait, we can't do that" moments during technical design.
+
+**Architecture decisions locked before code.** The shared-schema multi-tenancy decision, immutable distribution records design, and `ComplianceConstants` pattern were all decided and documented before a single line of production code was written. This is the correct order. Rework from late architectural pivots is far more expensive than planning time.
+
+**Compliance constants centralized from day zero.** Designing `ComplianceConstants.java` as the single source of truth for all CanG quota values (25g/day, 50g/month, etc.) prevents the most dangerous class of compliance bug: magic numbers scattered across the codebase that diverge when the law changes.
+
+**ComfyUI mockup images in minutes.** Generating 5 realistic UI mockup images with FLUX.1-schnell took approximately 8 minutes of wall-clock time. This provides a visual reference for the UI that would otherwise require a designer or Figma skills. The images are good enough for stakeholder presentations and early user research.
+
+**Test plan written before code.** TC-001 through TC-026 were defined against specifications, not against existing implementation. This forces clarity on what the code must do before writing it — the test cases are essentially executable requirements.
+
+---
+
+## What Was Challenging ⚠️
+
+**ComfyUI manual startup friction.** The ComfyUI image generation server does not auto-start with the system. This required manual service start and a retry cycle before image generation could proceed. The fix (systemd user service + auto-start lifespan check in `mcp-image-gen`) was implemented during this planning sprint but added unexpected overhead.
+
+**Solo developer timeline is ambitious.** The 18–24 month estimate for a production-ready SaaS while employed full-time at ADP Germany is tight. Sprint 1 goals are achievable; the risk accumulates in Sprints 3–6 when frontend work, billing integration, and PDF generation converge. The PrimeFaces JSF choice for MVP was deliberate to reduce this risk — existing Java frontend skills transfer directly.
+
+**Spring Boot 3 is not yet a "home" stack.** ADP work uses Jakarta EE (JBoss, CDI, JAX-RS). Spring Boot 3 shares the JPA/Hibernate mental model but diverges on dependency injection, auto-configuration, and application packaging. The learning curve is real but bounded — the `mss-failsafe` and `wellmann-shop` projects in `pi_mcps` demonstrate that the transition is manageable.
+
+**Next.js/React remains a significant gap.** The v2 frontend pivot to Next.js 15 + React 19 is the highest-skill-gap risk in the project. PrimeFaces buys time, but the clock starts ticking on React learning from Sprint 1. Deferring is correct; ignoring it is not.
+
+**No real user validation yet.** The entire architecture and pricing model is based on market research and regulatory reading, not on conversations with actual club administrators. The product may be solving the right problem in the wrong way. This is the most important open risk.
+
+---
+
+## Key Decisions Made 📋
+
+| Decision | Rationale | Alternatives rejected |
+|----------|-----------|----------------------|
+| Shared-schema multi-tenancy (single DB, `tenant_id` columns) | Lowest ops overhead for MVP; one DB to backup/restore; simpler Flyway migrations | Schema-per-tenant (complex provisioning), DB-per-tenant (expensive at scale) |
+| Immutable distribution records (`@Column(updatable = false)`) | Legal integrity — audit logs must be tamper-proof; corrections via `RecallEvent`, not `UPDATE` | Mutable records (simpler but legally risky under CanG §26 record-keeping) |
+| PrimeFaces JSF for MVP frontend | Leverages existing Jakarta EE skills; fastest path to working product; no JS build tooling required | React/Next.js (faster modern dev, but higher skill gap), Thymeleaf (less interactive) |
+| No public club discovery — permanent architectural exclusion | CanG §§6–7 prohibit advertising cannabis to the general public; club lookup tool would likely constitute advertising | N/A — this is a legal constraint, not a design choice |
+| `ComplianceConstants.java` single source of truth | Prevents magic number scatter; single change point when law evolves | Constants in each service (fragile), DB-configurable limits (dangerous — allows disabling compliance) |
+| Hetzner VPS over AWS/GCP | Cost (€5.88/month vs €20+); EU data residency (GDPR); simpler ops for solo developer | AWS (expensive, complex), Fly.io (less EU clarity), Railway (vendor lock-in) |
+
+---
+
+## Risks Going Forward ⚠️
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| New German government tightens CanG (e.g. lower quota limits) | Medium | High — requires rapid compliance updates | `ComplianceConstants.java` centralizes all limits; update is a 1-file change + test re-run |
+| Stripe flags account as cannabis-adjacent | Medium | Critical — billing becomes unusable | Use category "Vereinsverwaltung" (club management) in Stripe onboarding; prepare Mollie as fallback |
+| Solo dev burnout / timeline slip | High | Medium — delayed launch, not cancellation | Strict MVP scope; PrimeFaces reduces frontend effort; no scope creep before first paying customer |
+| Market timing risk — clubs adopt ad-hoc Excel/WhatsApp solutions | Medium | High — low willingness to pay for formal software | User research with 3+ clubs in Sprint 1 is mandatory before writing production code |
+| Legal risk: CanG compliance interpretation | Low | High — criminal liability for club officers | Specialist cannabis law opinion (€300–500) before launch; not optional |
+| Under-21 age calculation edge cases | Low | Medium — compliance bug | Birthday-based age calculation uses `Period.between()`, not year subtraction; tested in TC-013/014 |
+

+
+**B2B compliance and membership management SaaS for German cannabis social clubs (Cannabis-Anbauvereine).**
+
+---
+
+## What is CannaManage?
+
+Since April 2024, the Cannabisgesetz (CanG) permits licensed non-commercial social clubs to cultivate and distribute cannabis to their members. Each club must enforce strict distribution quotas, maintain tamper-proof audit logs, verify member eligibility, and comply with record-keeping obligations — all under threat of criminal liability for club officers.
+
+CannaManage is a purpose-built SaaS platform that makes these compliance obligations manageable. Club administrators get a single interface to track membership, record distributions against per-member quotas (25g/day, 50g/month for adults; 30g/month for under-21 members), manage cannabis stock batches, and generate the distribution logs required during official inspections.
+
+The platform is B2B only: it serves club administrators, not end consumers. It never stores member identities in a publicly discoverable way and contains no features that could be construed as advertising cannabis to the public — a legal requirement under CanG §§6–7. All data remains within the EU on Hetzner infrastructure.
+
+---
+
+## Key Features (MVP)
+
+- **Member management** — Registration, age verification (18+ required), under-21 flagging, status lifecycle (ACTIVE → SUSPENDED → EXPELLED)
+- **Distribution tracking** — Real-time quota enforcement: 25g/day, 50g/month (adults), 30g/month (under-21), ≤10% THC for under-21 members
+- **Compliance audit log** — Immutable distribution records; no `UPDATE` or `DELETE` on completed distributions
+- **Stock & batch management** — Strain catalogue with THC/CBD percentages, batch tracking from intake to zero, batch recall with member notification
+- **Multi-tenancy** — Full data isolation per club; shared-schema architecture with `tenant_id` filter
+- **PDF compliance reports** — iText 7 generated distribution logs formatted for regulatory inspection
+- **Stripe billing integration** — Subscription management per club; 4-tier pricing; webhook-driven provisioning
+- **Member self-service portal** — Quota dashboard, personal distribution history, appointment booking
+- **Role-based access** — ROLE_ADMIN (club officers), ROLE_MEMBER (read-only self-service)
+- **JWT authentication** — Stateless API with short-lived access tokens and secure refresh token rotation

+
+| Tier | Price | Members | Key inclusions |
+|------|-------|---------|----------------|
+| **Starter** | €29/month | Up to 50 | Core compliance, basic reports |
+| **Growth** | €59/month | Up to 150 | + PDF exports, email notifications |
+| **Professional** | €99/month | Up to 500 | + Stripe billing, priority support |
+| **Enterprise** | €199/month | Unlimited | + Custom reports, API access, SLA |
+
+All tiers include a 30-day free trial. Annual billing available at 2 months free (×10/12 monthly rate).
+
+**Market sizing:** Germany had approximately 3,000+ registered cannabis social clubs as of early 2026. At average Growth tier pricing, TAM is approximately €2.85M ARR.
+
+---
+
+## Legal Notice
+
+CannaManage operates exclusively as a B2B SaaS tool for licensed Cannabis-Anbauvereine registered under CanG (Cannabisgesetz, effective April 2024). Key legal positions:
+
+- **No public directory:** CannaManage contains no feature that enables public discovery of clubs or their locations. Club data is never exposed publicly or to other clubs.
+- **No advertising:** The platform does not advertise cannabis products to consumers. Club admins manage their own members — no public-facing cannabis content.
+- **CanG compliance:** Quota limits (25g/day, 50g/month for adults; 30g/month for under-21 members; ≤10% THC for under-21) are hardcoded constants, not configurable per club. This prevents compliance from being accidentally disabled.
+- **GDPR:** All data stored on EU infrastructure (Hetzner, Germany/Finland datacenters). Member personal data handled under GDPR legitimate interest basis (club membership) and statutory record-keeping obligation (CanG §26).
+- **Minimum age:** Club membership and therefore access to the member portal requires age 18+, verified at registration.
+
+*CannaManage is a management tool, not a cannabis marketplace. Club officers remain personally responsible for their club's legal compliance under CanG.*
+
+---
+
+## Development Status
+
+**Phase 0 — Foundation (Planning) — ✅ Complete as of 2026-04-06**
+
+The complete documentation suite (10 documents) has been written, covering architecture, API specification, data model, wireframes, test plan, and deployment guide. No production code has been written yet.
+
+**Sprint 1 goals (next):**
+- [ ] Initialize Spring Boot 3.x Maven multi-module project
+- [ ] Implement `AbstractTenantEntity` and Flyway baseline migration (`V1__initial_schema.sql`)
+- [ ] Build `ComplianceService` with 100% test coverage (TC-001 through TC-010)
+- [ ] Validate concept with 3 real club admins
+- [ ] Obtain specialist legal opinion on CanG compliance approach

+# FLUX.2 Klein 4B + Heretic — Session Recap
+
+**Date:** 2026-04-10  
+**Status:** Code complete, live generation BLOCKED by encoder dimension mismatch  
+
+---
+
+## What We Achieved ✅
+
+### Code Infrastructure (Solid)
+- **`mcp-image-gen/src/server.py`** — Generic workflow registry with model-based dispatch, `_inject_workflow_params()` works recursively on any node layout
+- **`mcp-image-gen/tests/test_server.py`** — 37/37 tests passing
+- **Gitea** — pushed to main (commit `38d26ad`)
+- The architecture is right: adding a new model = add 1 JSON file + 1 registry entry
+
+### Models Downloaded (on disk)
+| File | Location | Status |
+|------|----------|--------|
+| `flux-2-klein-4b.safetensors` | `~/ComfyUI/models/diffusion_models/` | ✅ 7.3GB |
+| `qwen_3_4b_bfl.safetensors` | `~/ComfyUI/models/text_encoders/` | ✅ merged from BFL shards |
+| `qwen_3_4b.safetensors` (z_image) | `~/ComfyUI/models/text_encoders/split_files/` | ✅ wrong model |
+| `Qwen3-4B-Q8_0.gguf` | `~/ComfyUI/models/text_encoders/` | ✅ wrong arch |
+| ComfyUI-GGUF extension | `~/ComfyUI/custom_nodes/ComfyUI-GGUF` | ✅ installed |
+
+---
+
+## What Failed and Why ❌
+
+### The Error (persistent)
+```
+mat1 and mat2 shapes cannot be multiplied (512x4096 and 7680x3072)
+```
+
+### Root Cause Analysis
+
+**Node 13** (`SamplerCustomAdvanced`) fails — meaning the conditioning vector from the text encoder doesn't match the diffusion model's expected input.
+
+| Component | Expected | Got |
+|-----------|----------|-----|
+| FLUX.2 Klein 4B conditioning input | **7680-dim** (2560 × 3) | **4096-dim** |
+
+**Why 7680 = 2560 × 3?**  
+FLUX models concatenate text embeddings across multiple time steps. The BFL Qwen3 encoder has `hidden_size=2560`, so the concatenated output is 2560×3=7680.
+
+**Why 4096?**  
+Every other Qwen3 variant (z_image_turbo, official Qwen repo GGUF) uses standard Qwen3 with `hidden_size=4096` — these are for Z-Image and text generation respectively, NOT for FLUX.2 Klein.
+
+### What We Tried (and Why Each Failed)
+1. `CLIPLoader type=flux` → wrong architecture (FLUX.1 style)
+2. `CLIPLoader type=flux2` → correct node, wrong encoder file (z_image Qwen)
+3. `CLIPLoaderGGUF type=flux2` → correct node, wrong GGUF (standard Qwen3)
+4. `CLIPLoader type=flux2 + qwen_3_4b_bfl.safetensors` → merged BFL shards, but still fails
+5. Workflow: `KSampler` → doesn't work with FLUX.2 (different architecture)
+6. Workflow: `SamplerCustomAdvanced + BasicGuider + Flux2Scheduler` → correct architecture but encoding mismatch persists
+
+### The Real Missing Piece
+
+The BFL FLUX.2 Klein text encoder in Diffusers format is designed for use via `transformers/diffusers` pipeline, NOT via ComfyUI's `CLIPLoader`. ComfyUI reads the weights differently. The weights are there but ComfyUI doesn't know how to map `model.embed_tokens`, `model.layers.N.*` etc. to the CLIP interface it expects.
+
+**The correct encoder file for ComfyUI** is `Comfy-Org/vae-text-encorder-for-flux-klein-4b` — the 7.5GB file we downloaded IS the right one, but ComfyUI is likely loading it with the wrong adapter in the `CLIPLoader`.
+
+---
+
+## Clean Approach — What We Need to Do
+
+### Option A: Use ComfyUI Web UI (Easiest)
+1. Open `http://localhost:8188` in browser
+2. Load the "Flux.2 Klein 4B Text-to-Image" workflow template (it's in the UI Templates)
+3. **Export the working API JSON** (Ctrl+Shift+E or Settings → Save as API format)
+4. Replace our `flux2_klein_heretic.json` with the exported JSON
+5. Add placeholders and test
+
+This gives us the **verified working node graph** without guessing. 10 minutes.
+
+### Option B: Find a Working API JSON online
+- Reddit r/comfyui has working FLUX.2 Klein workflows
+- Export format is what we need
+
+### Then: Add Heretic
+Once we have a working standard workflow:
+1. Download the actual Heretic-abliterated version of the BFL encoder (once it's published)
+2. Swap encoder filename in the JSON
+
+---
+
+## My Recommendation
+
+**Do Option A right now.** Open `http://localhost:8188`, load the template, export to API format, paste the JSON. We'll be running in 10 minutes instead of guessing node names.
+
+The MCP server code is solid — the only broken piece is `flux2_klein_heretic.json`. Once we have the right JSON from the UI, everything else works.
+
+---
+
+## Files to Clean Up (After We Have the Right JSON)
+
+```bash
+# Remove wrong encoders (save ~8GB)
+rm ~/ComfyUI/models/text_encoders/qwen_3_4b.safetensors   # z_image version
+rm ~/ComfyUI/models/text_encoders/qwen_3_4b_flux2.safetensors
+
+# Keep
+# ~/ComfyUI/models/text_encoders/qwen_3_4b_bfl.safetensors  ← correct encoder
+# ~/ComfyUI/models/text_encoders/Qwen3-4B-Q8_0.gguf          ← maybe useful later
+```

+# Plan: FLUX.2 Klein 4B + Heretic Abliterated Text Encoder in mcp-image-gen
+
+**Datum:** 2026-04-10  
+**Autor:** Lumen / Patrick Plate  
+**Status:** Ready for Implementation
+
+---
+
+## Ziel
+
+Das bestehende `mcp-image-gen` ComfyUI-Backend um ein zweites Modell erweitern:
+**FLUX.2 Klein 4B** mit dem abliterierten **Qwen3-4B-Heretic** als Text-Encoder.
+
+Ergebnis: `generate_image` kann via `model`-Parameter zwischen zwei Workflows wählen:
+- `flux1-schnell.safetensors` → bestehender Workflow (unverändert)
+- `flux-2-klein-4b-fp8.safetensors` → neuer Heretic-Workflow (keine Prompt-Refusals)
+
+---
+
+## Technischer Hintergrund
+
+### Warum Heretic + FLUX.2 Klein?
+
+FLUX.2 Klein 4B verwendet **Qwen3-4B als LLM Text-Encoder** (statt CLIP+T5 wie bei FLUX.1).
+Dieser LLM-Encoder hat Safety-Alignment → verweigert bestimmte Prompts → abliterieren.
+
+`DreamFast/qwen3-4b-heretic` (HuggingFace):
+- **KL Divergenz: 0.0000** — null messbarer Modell-Schaden
+- Nur **3/100 Refusals** nach Heretic v1.2.0 (200 Trials)
+- Drop-in Replacement für `qwen_3_4b.safetensors`
+
+### Modell-Architektur Unterschied
+
+| | FLUX.1-schnell | FLUX.2 Klein 4B |
+|---|---|---|
+| Diffusion Model | `flux1-schnell.safetensors` (UNet) | `flux-2-klein-4b-fp8.safetensors` |
+| Text Encoder | `DualCLIPLoader` (T5+CLIP) | `CLIPLoader` (Qwen3-4B) |
+| VAE | `ae.safetensors` | `flux2-vae.safetensors` |
+| Steps | 4 | 4 (distilled) |
+| VRAM | ~8GB | ~8.4GB |
+| Refusals | keine (kein LLM-Encoder) | keine (abliteriert) |
+

+## Phase 1: Modelle herunterladen
+
+### 1a. FLUX.2 Klein 4B (Diffusion Model)
+```bash
+# Von Black Forest Labs HuggingFace
+huggingface-cli download black-forest-labs/FLUX.2-klein-4B \
+  flux-2-klein-4b-fp8.safetensors \
+  --local-dir ~/ComfyUI/models/diffusion_models/
+```
+

+```bash
+huggingface-cli download black-forest-labs/FLUX.2-klein-4B \
+  flux2-vae.safetensors \
+  --local-dir ~/ComfyUI/models/vae/
+```
+
+### 1c. Qwen3-4B-Heretic (abliterierter Text-Encoder)
+```bash
+# Von DreamFast — bereits abliteriert, kein Heretic-Run nötig
+huggingface-cli download DreamFast/qwen3-4b-heretic \
+  --local-dir /tmp/qwen3-4b-heretic/

+cp /tmp/qwen3-4b-heretic/model.safetensors \
+   ~/ComfyUI/models/text_encoders/qwen_3_4b_heretic.safetensors
+```
+
+> **Hinweis:** DreamFast/qwen3-4b-heretic ist ein GGUF-/SafeTensors-Mix.
+> Wir brauchen die `.safetensors` Variante für ComfyUI. Falls nur GGUF verfügbar:
+> `huggingface-cli download Lockout/qwen3-4b-heretic-zimage qwen-4b-zimage-hereticV2-q8.gguf`

+
+## Phase 3: server.py — Workflow-Registry
+
+### Änderung 1: Workflow-Registry dict (nach `_WORKFLOW_PATH`)
+
+```python
+# Path to the bundled FLUX.1-schnell workflow template
+_WORKFLOW_PATH = Path(__file__).parent / "workflows" / "flux_schnell.json"
+
+# Workflow registry: model filename → workflow JSON path
+_WORKFLOW_REGISTRY: dict[str, Path] = {
+    "flux1-schnell.safetensors": Path(__file__).parent / "workflows" / "flux_schnell.json",
+    "flux-2-klein-4b-fp8.safetensors": Path(__file__).parent / "workflows" / "flux2_klein_heretic.json",
+}
+
+_DEFAULT_MODEL = "flux1-schnell.safetensors"
+```
+
+### Änderung 2: `_load_workflow()` Hilfsfunktion
+
+```python
+def _load_workflow(model: str) -> dict:
+    """Load the correct workflow JSON for the requested model.
+    
+    Falls back to FLUX.1-schnell if model not in registry.
+    """
+    path = _WORKFLOW_REGISTRY.get(model, _WORKFLOW_PATH)
+    if not path.exists():
+        raise FileNotFoundError(f"Workflow JSON not found: {path}")
+    return json.loads(path.read_text())
+```
+
+### Änderung 3: `_generate_single()` nutzt Registry
+
+Aktueller Code lädt immer `_WORKFLOW_PATH`. Änderung: `_load_workflow(model)` aufrufen:
+
+```python
+async def _generate_single(
+    client: ComfyUIClient,
+    prompt: str,
+    negative_prompt: str,
+    model: str,
+    seed: int,
+    width: int,
+    height: int,
+    steps: int,
+    output_dir: Path,
+    name: str,
+) -> tuple[TextContent, ImageContent | None]:
+    workflow = _load_workflow(model)  # ← statt json.loads(_WORKFLOW_PATH.read_text())
+    # ... rest unchanged
+```
+
+---
+
+## Phase 4: Tests
+
+Neue Tests in [`mcp/mcp-image-gen/tests/test_server.py`](mcp/mcp-image-gen/tests/test_server.py):
+
+1. **`test_workflow_registry_contains_both_models`** — Registry hat flux1-schnell + flux2-klein
+2. **`test_load_workflow_flux1_schnell`** — lädt flux_schnell.json korrekt
+3. **`test_load_workflow_flux2_klein`** — lädt flux2_klein_heretic.json korrekt
+4. **`test_load_workflow_unknown_model_falls_back`** — unbekanntes Modell → FLUX.1-schnell
+5. **`test_generate_image_uses_flux2_workflow`** — end-to-end Mock mit flux-2-klein-4b-fp8.safetensors
+
+---
+
+## Phase 5: USAGE.md Update
+
+Neuer Abschnitt "FLUX.2 Klein 4B (Heretic)" in [`mcp/mcp-image-gen/USAGE.md`](mcp/mcp-image-gen/USAGE.md):
+- Download-Befehle für alle 3 neuen Modell-Dateien
+- Erklärung warum Heretic (abliterierter Text-Encoder, KL=0)
+- Beispiel-Aufruf: `generate_image("...", model="flux-2-klein-4b-fp8.safetensors")`

+
+## VRAM-Analyse
+
+| Modell | VRAM gesamt | Passt in 24GB? |
+|---|---|---|
+| FLUX.1-schnell (fp8) | ~8GB | ✅ |
+| FLUX.2 Klein 4B (fp8) + Qwen3-4B | ~8.4GB + ~4GB = ~12.4GB | ✅ |
+| Beide gleichzeitig geladen | ~20GB | ✅ mit Margin |
+
+Der RX 7900 XTX mit 24GB VRAM kann beide Modelle komfortabel halten.
+

+
+## Risiken & Mitigationen
+
+| Risiko | Wahrscheinlichkeit | Mitigation |
+|---|---|---|
+| `CLIPLoader` node nicht verfügbar in ComfyUI | niedrig | ComfyUI updaten; alternativ custom node |
+| DreamFast-Modell nur als GGUF verfügbar | mittel | Lockout/qwen3-4b-heretic-zimage GGUF als Fallback |
+| Qwen3-4B braucht anderen node type | mittel | Live-Test in ComfyUI UI zuerst; workflow anpassen |
+| ROCm + Qwen3-4B Kompatibilität | niedrig | gleiche ROCm-Umgebung wie FLUX.1-schnell |
+
+---
+
+## Entscheidung
+
+✅ **Empfehlung: Umsetzen.** Minimale Code-Änderungen, kein Breaking Change, klarer Mehrwert.
+
+Der einzige unsichere Punkt ist der genaue ComfyUI-Node-Name für den Qwen3-4B-Loader.
+**Empfohlene Vorgehensweise:** Erst in der ComfyUI-Web-UI manuell einen Workflow mit Qwen3-4B aufbauen → JSON exportieren → als `flux2_klein_heretic.json` speichern. Das garantiert korrekte Node-Namen ohne Guess-Work.
