+create a module vfs_mail in @lib/vfs 
+check the interface as defined in @lib/vfs/interface.v and @metadata.v 
+
+see example how a vfs is made in @lib/vfs/vfs_local 
+
+create the vfs to represent mail objects in @lib/circles/dbs/core/mail_db.v 
+
+mailbox propery on the Email object defines the path in the vfs
+this mailbox property can be e.g. Draft/something/somethingelse
+
+in that dir show a subdir /id:
+-  which show the Email as a json underneith the ${email.id}.json
+
+in that dir show subdir /subject:
+-  which show the Email as a json underneith the name_fix(${email.envelope.subject}.json
+
+so basically we have 2 representations of the same mail in the vfs, both have the. json as content of the file

-# HeroLib Job DBSession
+# Circles Core Models
 
-This document explains the job management system in HeroLib, which is designed to coordinate distributed task execution across multiple agents.
+This directory contains the core data structures used in the herolib circles module. These models serve as the foundation for the circles functionality, providing essential data structures for agents, circles, and name management.
 
-## Core Components
+## Overview
 
-### 1. Job System
+The core models implement the Serializer interface, which allows them to be stored and retrieved using the generic Manager implementation. Each model provides:
 
-The job system is the central component that manages tasks to be executed by agents. It consists of:
+- A struct definition with appropriate fields
+- Serialization methods (`dumps()`) for converting to binary format
+- Deserialization functions (`*_loads()`) for recreating objects from binary data
+- Index key methods for efficient lookups
 
-- **Job**: Represents a task to be executed by an agent. Each job has:
-  - A unique GUID
-  - Target agents (public keys of agents that can execute the job)
-  - Source (public key of the agent requesting the job)
-  - Circle and context (organizational structure)
-  - Actor and action (what needs to be executed)
-  - Parameters (data needed for execution)
-  - Timeout settings
-  - Status information
-  - Dependencies on other jobs
+## Core Models
 
-- **JobStatus**: Tracks the state of a job through its lifecycle:
-  - created → scheduled → planned → running → ok/error
+### Agent (`agent.v`)
 
-- **JobManager**: Handles CRUD operations for jobs, storing them in Redis under the `herorunner:jobs` key.
+The Agent model represents a self-service provider that can execute jobs:
 
-### 2. Agent System
+- **Agent**: Main struct with fields for identification, communication, and status
+- **AgentService**: Represents services provided by an agent
+- **AgentServiceAction**: Defines actions that can be performed by a service
+- **AgentStatus**: Tracks the operational status of an agent
+- **AgentState**: Enum for possible agent states (ok, down, error, halted)
+- **AgentServiceState**: Enum for possible service states
 
-The agent system represents the entities that can execute jobs:
+### Circle (`circle.v`)
 
-- **Agent**: Represents a service provider that can execute jobs. Each agent has:
-  - A public key (identifier)
-  - Network address and port
-  - Status information
-  - List of services it provides
-  - Cryptographic signature for verification
+The Circle model represents a collection of members (users or other circles):
 
-- **AgentService**: Represents a service provided by an agent, with:
-  - Actor name
-  - Available actions
-  - Status information
+- **Circle**: Main struct with fields for identification and member management
+- **Member**: Represents a member of a circle with personal information and role
+- **Role**: Enum for possible member roles (admin, stakeholder, member, contributor, guest)
 
-- **AgentManager**: Handles CRUD operations for agents, storing them in Redis under the `herorunner:agents` key.
+### Name (`name.v`)
 
-### 3. Service System
+The Name model provides DNS record management:
 
-The service system defines the capabilities available in the system:
+- **Name**: Main struct for domain management with records and administrators
+- **Record**: Represents a DNS record with name, text, category, and addresses
+- **RecordType**: Enum for DNS record types (A, AAAA, CNAME, MX, etc.)
 
-- **Service**: Represents a capability that can be provided by agents. Each service has:
-  - Actor name
-  - Available actions
-  - Status information
-  - Optional access control list
+## Usage
 
-- **ServiceAction**: Represents an action that can be performed by a service, with:
-  - Action name
-  - Parameters
-  - Optional access control list
+These models are used by the circles module to manage agents, circles, and DNS records. They are typically accessed through the database handlers that implement the generic Manager interface.
 
-- **ServiceManager**: Handles CRUD operations for services, storing them in Redis under the `herorunner:services` key.
+## Serialization
 
-### 4. Access Control System
+All models implement binary serialization using the encoder module:
 
-The access control system manages permissions:
+- Each model type has a unique encoding ID (Agent: 100, Circle: 200, Name: 300)
+- The `dumps()` method serializes the struct to binary format
+- The `*_loads()` function deserializes binary data back into the struct
 
-- **Circle**: Represents a collection of members (users or other circles)
-- **ACL**: Access Control List containing multiple ACEs
-- **ACE**: Access Control Entry defining permissions for users or circles
-- **CircleManager**: Handles CRUD operations for circles, storing them in Redis under the `herorunner:circles` key.
+## Database Integration
 
-### 5. HeroRunner
+The models are designed to work with the generic Manager implementation through:
 
-The `HeroRunner` is the main factory that brings all components together, providing a unified interface to the job management system.
-
-## How It Works
-
-1. **Job Creation and Scheduling**:
-   - A client creates a job with specific actor, action, and parameters
-   - The job is stored in Redis with status "created"
-   - The job can specify dependencies on other jobs
-
-2. **Agent Registration**:
-   - Agents register themselves with their public key, address, and services
-   - Each agent provides a list of services (actors) and actions it can perform
-   - Agents periodically update their status
-
-3. **Service Discovery**:
-   - Services define the capabilities available in the system
-   - Each service has a list of actions it can perform
-   - Services can have access control to restrict who can use them
-
-4. **Job Execution**:
-   - The herorunner process monitors jobs in Redis
-   - When a job is ready (dependencies satisfied), it changes status to "scheduled"
-   - The herorunner forwards the job to an appropriate agent
-   - The agent changes job status to "planned", then "running", and finally "ok" or "error"
-   - If an agent fails, the herorunner can retry with another agent
-
-5. **Access Control**:
-   - Users and circles are organized in a hierarchical structure
-   - ACLs define who can access which services and actions
-   - The service manager checks access permissions before allowing job execution
-
-## Data Storage
-
-All data is stored in Redis using the following keys:
-- `herorunner:jobs` - Hash map of job GUIDs to job JSON
-- `herorunner:agents` - Hash map of agent public keys to agent JSON
-- `herorunner:services` - Hash map of service actor names to service JSON
-- `herorunner:circles` - Hash map of circle GUIDs to circle JSON
-
-## Potential Issues
-
-1. **Concurrency Management**:
-   - The current implementation doesn't have explicit locking mechanisms for concurrent access to Redis
-   - Race conditions could occur if multiple processes update the same job simultaneously
-
-2. **Error Handling**:
-   - While there are error states, the error handling is minimal
-   - There's no robust mechanism for retrying failed jobs or handling partial failures
-
-3. **Dependency Resolution**:
-   - The code for resolving job dependencies is not fully implemented
-   - It's unclear how circular dependencies would be handled
-
-4. **Security Concerns**:
-   - While there's a signature field in the Agent struct, the verification process is not evident
-   - The ACL system is basic and might not handle complex permission scenarios
-
-5. **Scalability**:
-   - All data is stored in Redis, which could become a bottleneck with a large number of jobs
-   - There's no apparent sharding or partitioning strategy
-
-6. **Monitoring and Observability**:
-   - Limited mechanisms for monitoring the system's health
-   - No built-in logging or metrics collection
-
-## Recommendations
-
-1. Implement proper concurrency control using Redis transactions or locks
-2. Enhance error handling with more detailed error states and recovery mechanisms
-3. Develop a robust dependency resolution system with cycle detection
-4. Strengthen security by implementing proper signature verification and enhancing the ACL system
-5. Consider a more scalable storage solution for large deployments
-6. Add comprehensive logging and monitoring capabilities
-
-## Usage Example
-
-```v
-// Initialize the HeroRunner
-mut hr := model.new()!
-
-// Create a new job
-mut job := hr.jobs.new()
-job.guid = 'job-123'
-job.actor = 'vm_manager'
-job.action = 'start'
-job.params['id'] = '10'
-hr.jobs.set(job)!
-
-// Register an agent
-mut agent := hr.agents.new()
-agent.pubkey = 'agent-456'
-agent.address = '192.168.1.100'
-agent.services << model.AgentService{
-    actor: 'vm_manager'
-    actions: [
-        model.AgentServiceAction{
-            action: 'start'
-            params: {'id': 'string'}
-        }
-    ]
-}
-hr.agents.set(agent)!
-
-// Define a service
-mut service := hr.services.new()
-service.actor = 'vm_manager'
-service.actions << model.ServiceAction{
-    action: 'start'
-    params: {'id': 'string'}
-}
-hr.services.set(service)!
-```

-## Circle Management with HeroScript
-
-You can use HeroScript to create and manage circles. Here's an example of how to create a circle and add members to it:
-
-```heroscript
-!!circle.create
-    name: 'development'
-    description: 'Development team circle'
-
-!!circle.add_member
-    circle: 'development'
-    name: 'John Doe'
-    pubkey: 'user-123'
-    email: 'john@example.com'
-    role: 'admin'
-    description: 'Lead developer'
-
-!!circle.add_member
-    circle: 'development'
-    name: 'Jane Smith'
-    pubkeys: 'user-456,user-789'
-    emails: 'jane@example.com,jsmith@company.com'
-    role: 'member'
-    description: 'Frontend developer'

-## Domain Name Management with HeroScript
-
-You can use HeroScript to create and manage domain names and DNS records. Here's an example of how to create a domain and add various DNS records to it:
-
-```heroscript
-!!name.create
-    domain: 'example.org'
-    description: 'Example organization domain'
-    admins: 'admin1-pubkey,admin2-pubkey'
-
-!!name.add_record
-    domain: 'example.org'
-    name: 'www'
-    type: 'a'
