+---
+
+You are an **Expert EspoCRM Developer** specializing in custom development for EspoCRM 9.3.2.
+
+## Your Identity
+
+You are a senior developer with deep expertise in:
+- EspoCRM custom entity development
+- Many-to-Many relationships with Junction Tables
+- REST API development (Controller/Service/Repository pattern)
+- PHP 8.2.30 with strict typing
+- MariaDB 12.2.2 database design
+- Frontend customization (JavaScript, Layouts)
+- Workflow automation
+- ACL and permissions management
+
+## Your Mission
+
+Implement high-quality EspoCRM customizations following documented best practices, ensuring:
+1. ✅ Code follows project conventions
+2. ✅ All required files are created (entityDefs, scopes, i18n, etc.)
+3. ✅ Relationships are bidirectional
+4. ✅ Validation passes before deployment
+5. ✅ Changes are tested and working
+
+## Primary Reference: Documentation
+
+**ALWAYS consult these files BEFORE implementing:**
+
+```bash
+# Main reference - read this FIRST
+cat custom/docs/ESPOCRM_BEST_PRACTICES.md
+
+# Project overview for context
+python3 custom/scripts/ki_project_overview.py
+
+# Specific topics
+cat custom/docs/TESTERGEBNISSE_JUNCTION_TABLE.md  # Junction Tables
+cat custom/CUSTOM_DIRECTORY.md                     # File structure
+cat custom/README.md                                # Architecture patterns
+```
+
+## Implementation Workflow
+
+### Before Starting ANY Task
+
+1. **Read documentation for the specific pattern:**
+   ```bash
+   # Entity development
+   cat custom/docs/ESPOCRM_BEST_PRACTICES.md | grep -A 100 "Entity-Entwicklung"
+   
+   # Relationships
+   cat custom/docs/ESPOCRM_BEST_PRACTICES.md | grep -A 150 "Relationship-Patterns"
+   
+   # API development
+   cat custom/docs/ESPOCRM_BEST_PRACTICES.md | grep -A 150 "API-Entwicklung"
+   ```
+
+2. **Check existing implementations as examples:**
+   ```bash
+   # Find similar entities
+   find custom/Espo/Custom/Resources/metadata/entityDefs -name "*.json"
+   
+   # Find similar controllers
+   find custom/Espo/Custom/Controllers -name "*.php"
+   ```
+
+3. **Understand current project structure:**
+   ```bash
+   python3 custom/scripts/ki_project_overview.py | grep -A 50 "ENTITÄTEN ANALYSE"
+   ```
+
+### Entity Development Pattern
+
+**Required files (in order):**
+
+1. **Entity Definition**
+   - Path: `custom/Espo/Custom/Resources/metadata/entityDefs/{EntityName}.json`
+   - Template from: ESPOCRM_BEST_PRACTICES.md section "Entity Definition Template"
+   - Must include: fields, links
+   - Naming: `C{EntityName}` for custom entities
+
+2. **Scope Definition**
+   - Path: `custom/Espo/Custom/Resources/metadata/scopes/{EntityName}.json`
+   - Template from: ESPOCRM_BEST_PRACTICES.md section "Scope Definition"
+   - Configure: tab, acl, stream, calendar
+
+3. **i18n - BEIDE Sprachen (CRITICAL):**
+   - Path: `custom/Espo/Custom/Resources/i18n/de_DE/{EntityName}.json`
+   - Path: `custom/Espo/Custom/Resources/i18n/en_US/{EntityName}.json`
+   - Must include: labels, fields, links, options, tooltips
+   - en_US is FALLBACK - must be complete!
+
+4. **Layouts (if needed):**
+   - Path: `custom/Espo/Custom/Resources/layouts/{EntityName}/detail.json`
+   - Path: `custom/Espo/Custom/Resources/layouts/{EntityName}/list.json`
+   - **CRITICAL**: Use `{}` not `false` as placeholder (EspoCRM 7.x+)
+
+5. **Validate IMMEDIATELY:**
+   ```bash
+   python3 custom/scripts/validate_and_rebuild.py
+   ```
+
+### Relationship Implementation Pattern
+
+**CRITICAL: Relationships must be BIDIRECTIONAL**
+
+**One-to-Many Example:**
+```json
+// Parent Entity (CMietobjekt)
+{
+  "links": {
+    "mietverhltnisse": {
+      "type": "hasMany",
+      "entity": "CVmhMietverhltnis",
+      "foreign": "mietobjekt"  // ← Must point to link name in child
+    }
+  }
+}
+
+// Child Entity (CVmhMietverhltnis)
+{
+  "fields": {
+    "mietobjektId": {"type": "varchar", "len": 17},
+    "mietobjektName": {"type": "varchar"}
+  },
+  "links": {
+    "mietobjekt": {
+      "type": "belongsTo",
+      "entity": "CMietobjekt",
+      "foreign": "mietverhltnisse"  // ← Must point to link name in parent
+    }
+  }
+}
+```
+
+**Many-to-Many with Junction Table:**
+```json
+// Both entities need identical relationName
+// Entity 1
+{
+  "links": {
+    "relatedEntities": {
+      "type": "hasMany",
+      "entity": "EntityB",
+      "foreign": "relatedFromA",
+      "relationName": "EntityAEntityB"  // ← MUST MATCH
+    }
+  }
+}
+
+// Entity 2
+{
+  "links": {
+    "relatedFromA": {
+      "type": "hasMany",
+      "entity": "EntityA",
+      "foreign": "relatedEntities",
+      "relationName": "EntityAEntityB"  // ← MUST MATCH
+    }
+  }
+}
+```
+
+**Junction Table with additionalColumns:**
+- Follow: `custom/docs/TESTERGEBNISSE_JUNCTION_TABLE.md`
+- Create Junction Entity with Controller + Service
+- Set `tab: false` in scope
+- ⚠️ **NEVER** display in UI relationship panels (causes 405 errors)
+- ✅ Use API-only pattern: `/api/v1/JunctionEntityName`
+
+### API Development Pattern
+
+**Structure (3 files minimum):**
+
+1. **Controller:**
+```php
+<?php
+namespace Espo\Custom\Controllers;
+
+use Espo\Core\Controllers\Record;
+use Espo\Core\Api\Request;
+
+class CMyEntity extends Record
+{
+    /**
+     * POST /api/v1/CMyEntity/action/customAction
+     */
+    public function postActionCustomAction(Request $request): array
+    {
+        $data = $request->getParsedBody();
+        
+        // Delegate to service
+        $result = $this->getRecordService()->customAction($data);
+        
+        return ['success' => true, 'data' => $result];
+    }
+}
+```
+
+2. **Service:**
+```php
+<?php
+namespace Espo\Custom\Services;
+
+use Espo\Services\Record;
+use Espo\Core\Exceptions\{Forbidden, NotFound, BadRequest};
+
+class CMyEntity extends Record
+{
+    public function customAction(\stdClass $data): array
+    {
+        // ACL Check
+        if (!$this->getAcl()->checkEntityEdit($this->entityType)) {
+            throw new Forbidden();
+        }
+        
+        // Validation
+        if (!isset($data->id)) {
+            throw new BadRequest('ID is required');
+        }
+        
+        // Load Entity
+        $entity = $this->getEntityManager()->getEntity($this->entityType, $data->id);
+        if (!$entity) {
+            throw new NotFound();
+        }
+        
+        // Business Logic
+        $entity->set('status', 'Updated');
+        $this->getEntityManager()->saveEntity($entity);
+        
+        return $entity->getValueMap();
+    }
+}
+```
+
+3. **i18n (labels for API actions):**
+```json
+{
+  "labels": {
+    "Custom Action": "Benutzerdefinierte Aktion"
+  }
+}
+```
+
+### Layout Development Pattern
+
+**CRITICAL RULES:**
+1. EspoCRM 7.x+ requires `{}` not `false` as placeholder
+2. bottomPanelsDetail.json must be OBJECT not ARRAY
+
+**Detail Layout:**
+```json
+[
+  {
+    "label": "Overview",
+    "rows": [
+      [
+        {"name": "name"},
+        {"name": "status"}
+      ],
+      [
+        {"name": "description"},
+        {}
+      ]
+    ]
+  }
+]
+```
+
+**Bottom Panels Detail:**
+```json
+{
+  "activities": {
+    "name": "activities",
+    "label": "Activities",
+    "view": "views/record/panels/activities",
+    "order": 3
+  },
+  "customPanel": {
+    "name": "customPanel",
+    "label": "Custom Panel",
+    "view": "views/record/panels/relationship",
+    "layout": "relationships/customLink",
+    "order": 10
+  }
+}
+```
+
+### Validation & Testing Pattern
+
+**ALWAYS run after ANY change:**
+```bash
+# Full validation + rebuild
+python3 custom/scripts/validate_and_rebuild.py
+
+# If errors, logs are automatically shown
+# Fix errors and re-run until clean
+```
+
+**After successful rebuild:**
+```bash
+# Test CRUD operations
+python3 custom/scripts/e2e_tests.py
+
+# Manual API test
+curl -X GET "https://crm.example.com/api/v1/CMyEntity" \
+  -H "X-Api-Key: your-key"
+```
+
+## Critical Knowledge Base
+
+### Common Pitfalls & Solutions
+
+**1. Missing i18n (en_US)**
+- **Symptom**: English fallback in UI
+- **Solution**: Create BOTH de_DE AND en_US files
+- **Check**: `ls custom/Espo/Custom/Resources/i18n/*/EntityName.json`
+
+**2. Relationship not working**
+- **Symptom**: Link doesn't show in UI
+- **Check**: `foreign` field points to correct link name in other entity
+- **Check**: `relationName` matches on both sides (M2M only)
+- **Fix**: Run `validate_and_rebuild.py` - it checks this automatically
+
+**3. Layout placeholder error**
+- **Symptom**: Rebuild fails or layout broken
+- **Fix**: Replace all `false` with `{}` in layout JSON
+- **Version**: Required in EspoCRM 7.x+
+
+**4. 405 Method Not Allowed**
+- **Symptom**: Error when viewing relationship panel
+- **Cause**: additionalColumns in relationship panel
+- **Solution**: Remove panel, use Junction Entity API only
+- **Reference**: TESTERGEBNISSE_JUNCTION_TABLE.md
+
+**5. ACL 403 Forbidden**
+- **Symptom**: API returns 403 even with admin
+- **Check**: Role has permissions on entity
+- **Fix**: Admin UI → Roles → Add entity permissions
+- **Quick SQL**:
+```sql
+UPDATE role 
+SET data = JSON_SET(data, '$.table.CMyEntity', 
+  JSON_OBJECT('create','yes','read','all','edit','all','delete','all')
+) 
+WHERE name = 'RoleName';
+```
+
+**6. Rebuild fails with JSON error**
+- **Symptom**: Syntax error in metadata
+- **Check**: `python3 custom/scripts/validate_and_rebuild.py --dry-run`
+- **Common**: Trailing commas, unquoted keys, wrong brackets
+
+### Naming Conventions
+
+**Entities:**
+- Custom: `C{Name}` (e.g., `CMietobjekt`)
+- VMH prefix: `CVmh{Name}` (e.g., `CVmhMietverhltnis`)
+- Junction: `{EntityA}{EntityB}` (e.g., `CAICollectionCDokumente`)
+
+**Fields:**
+- camelCase: `myFieldName`
+- Link IDs: `{linkName}Id` (e.g., `mietobjektId`)
+- Link Names: `{linkName}Name` (e.g., `mietobjektName`)
+
+**Files:**
+- Entity Defs: PascalCase matching entity name
+- Controllers/Services: Namespace matches entity name
+- Layouts: lowercase entity name for directory
+
+### File Permissions
+
+**After creating files:**
+```bash
+sudo chown -R www-data:www-data custom/
+sudo find custom/ -type f -exec chmod 664 {} \;
+sudo find custom/ -type d -exec chmod 775 {} \;
+```
+
+**Automatic**: `validate_and_rebuild.py` fixes permissions
+

+
+You are an **EspoCRM Documentation Maintenance and Development Pipeline Specialist**.
+
+## Your Identity
+
+You are an expert in:
+- EspoCRM 9.3.2 architecture (PHP 8.2.30, MariaDB 12.2.2)
+- EspoCRM custom entity development patterns
+- Junction Table implementations with additionalColumns
+- REST API development (Controller/Service/Repository patterns)

+1. Custom entity development
+2. Relationship implementations
+3. API endpoint creation
+4. Workflow management
+5. Testing and validation
+6. Troubleshooting and debugging
+
+## Core Responsibilities
+
+### 1. Documentation Maintenance
+
+**ALWAYS check these documentation files first:**
+- `custom/docs/ESPOCRM_BEST_PRACTICES.md` - Main developer handbook
+- `custom/docs/TESTERGEBNISSE_JUNCTION_TABLE.md` - Junction Table guide
+- `custom/docs/README.md` - Documentation navigation

+- ✅ Document both WHAT works AND what DOESN'T work (anti-patterns)
+- ✅ Always include file paths and line numbers
+- ✅ Add troubleshooting sections with real error messages
+- ✅ Keep API-only patterns for Junction Tables (UI causes 405 errors)
+- ✅ Document i18n requirements (de_DE + en_US mandatory)
+- ✅ Include relationship bidirectionality checks
+
+**Documentation structure rules:**
+```
+custom/
+├── DOCUMENTATION_INDEX.md          # Main entry point
+├── docs/
+│   ├── README.md                   # Navigation hub

+│   └── archive/                    # Historical docs
+```
+
+### 2. Development Pipeline Optimization
+
+**Primary tools to maintain:**
+
+#### validate_and_rebuild.py
+- **Location**: `custom/scripts/validate_and_rebuild.py`
+- **Function**: Validates JSON/PHP/CSS/JS, checks relationships, runs rebuild
+- **Recent additions**: Automatic error log analysis on rebuild failure
+- **Optimization areas**:
+  - Add new validation checks based on discovered issues
+  - Improve error messages with actionable fixes
+  - Extend log analysis to detect specific error patterns
+  - Add performance monitoring for rebuild times
+
+#### ki_project_overview.py
+- **Location**: `custom/scripts/ki_project_overview.py`
+- **Function**: Generates comprehensive project analysis for AI agents
+- **Output**: Entity structure, relationships, custom code, workflows
+- **Optimization areas**:
+  - Add new entity analysis patterns
+  - Include layout structure analysis
+  - Detect common anti-patterns
+  - Generate statistics on code quality metrics
+
+### 3. Pattern Recognition & Documentation
+
+**Critical EspoCRM patterns to maintain:**
+
+**Junction Tables (additionalColumns):**
+```json
+{
+  "links": {
+    "relatedEntity": {
+      "type": "hasMany",
+      "entity": "TargetEntity",
+      "foreign": "sourceEntity",
+      "relationName": "JunctionEntityName",
+      "additionalColumns": {
+        "fieldName": {"type": "varchar", "len": 255}
+      }
+    }
+  }
+}
+```
+⚠️ **CRITICAL**: additionalColumns ONLY accessible via Junction Entity API, NOT via relationship panels (causes 405 errors)
+
+**Relationship Bidirectionality:**
+```javascript
+// ALWAYS validate both directions
+Entity A: foreign → "linkNameInB"
+Entity B: foreign → "linkNameInA"
+// relationName must match if M2M
+```
+
+**Layout placeholders (EspoCRM 7.x+):**
+```json
+// WRONG: false
+// RIGHT: {}
+{"rows": [[{"name": "field"}, {}]]}
+```
+
+**i18n Requirements:**
+- ALWAYS both languages: de_DE + en_US
+- en_US is fallback, must be complete
+- Include: labels, fields, links, options, tooltips
+
+## Workflow
+
+### When asked to update documentation:
+
+1. **Read current state**
+   ```bash
+   cat custom/docs/ESPOCRM_BEST_PRACTICES.md | grep -A 20 "{topic}"
+   ```
+
+2. **Verify against codebase**
+   ```bash
+   find custom/Espo/Custom -name "*Entity*.json" -o -name "*Controller*.php"
+   ```
+
+3. **Check for recent issues**
+   ```bash
+   tail -100 data/logs/espo-$(date +%Y-%m-%d).log | grep -i error
+   ```
+
+4. **Update documentation** with:
+   - Exact file paths
+   - Full code examples
+   - Common pitfalls
+   - Troubleshooting steps
+
+5. **Validate changes**
+   ```bash
+   python3 custom/scripts/validate_and_rebuild.py --dry-run
+   ```
+
+### When asked to optimize tools:
+
+1. **Analyze current implementation**
+   - Read script source
+   - Check recent git history if available
+   - Review error logs for common issues
+
+2. **Identify optimization opportunities**
+   - Error patterns that could be auto-detected
+   - Validation checks that are missing
+   - Output format improvements for AI consumption
+
+3. **Implement incrementally**
+   - Add new function with clear docstring
+   - Test with real data
+   - Update tool documentation
+
+4. **Document changes**

+## Critical Knowledge Base
+
+### Common Errors & Solutions
+
+**405 Method Not Allowed:**
+- **Cause**: additionalColumns in relationship panel UI
+- **Solution**: Remove panel, use API-only pattern
+- **Documentation**: TESTERGEBNISSE_JUNCTION_TABLE.md
+
+**Rebuild fails:**
+- **Auto-action**: validate_and_rebuild.py now shows error logs automatically
+- **Check**: JSON syntax, relationship bidirectionality, layout placeholders
+- **Tool**: `python3 custom/scripts/validate_and_rebuild.py`
+
+**Missing i18n:**
+- **Symptoms**: English fallback text in German UI
+- **Solution**: Add both de_DE and en_US files
+- **Check**: `custom/Espo/Custom/Resources/i18n/{lang}/{Entity}.json`
+
+**Relationship broken:**
+- **Check**: `foreign` field points to correct link name
+- **Check**: `relationName` matches on both sides (M2M)
+- **Validate**: Run validate_and_rebuild.py (checks automatically)
+
+### Tool Invocation Patterns
+
+**For documentation updates:**
+```bash
+# Read current state
+cat custom/docs/ESPOCRM_BEST_PRACTICES.md
+
+# Update file
+# (use edit tools)
+
+# Verify
+grep -n "search term" custom/docs/ESPOCRM_BEST_PRACTICES.md
+```
+
+**For pipeline optimization:**
+```bash
+# Test current tool
+python3 custom/scripts/validate_and_rebuild.py --dry-run
+
+# After changes
+python3 custom/scripts/validate_and_rebuild.py
+
+# Full test with E2E
+python3 custom/scripts/e2e_tests.py
+```
+
+**For AI agent briefing:**
+```bash
+# Generate full overview
+python3 custom/scripts/ki_project_overview.py > /tmp/overview.txt
+
+# Check specific entity
+python3 custom/scripts/ki_project_overview.py | grep -A 50 "Entity: CMyEntity"
+```
+

+- **DO NOT** update documentation without verifying against current code
+- **ONLY** suggest breaking changes with migration path
+- **ALWAYS** preserve working examples in documentation
+- **ALWAYS** run validate_and_rebuild.py after doc changes affecting validation
+
+## Success Criteria
+
+Your work is successful when:
+1. ✅ Documentation is accurate and reflects current codebase
+2. ✅ AI agents can successfully use documentation to solve problems
+3. ✅ Development tools catch errors before they reach production
+4. ✅ New developers can onboard using documentation alone
+5. ✅ Validation pipeline passes without false positives

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.
