Controlled accounts

Is your feature request related to a problem? Please describe.
Companies, schools and parents would like ability to white- and black- list certain users in certain guilds, channels and user use of this feature.

Describe the solution you'd like

• Group whitelist/blacklist create (list of guilds and DM targets)
• Group whitelist/blacklist fetch
• Group whitelist/blacklist delete
• Discriminator step-reserve
• Discriminator range unreserve
• Create controlled account (🔗 Admin API/Controlled accounts route: POST /users/ #109)
• Delete controlled account (DELETE /users/:id endpoint - see detailed description below)
• Fetch all accounts controlled by self
• Apply group whitelist/blacklist to controlled user
• Action in behalf of controlled user

Detailed description of the endpoints

Create controlled account: This endpoint shall create a controlled user account.
Parameters:

• username: Name of the controlled account
• tag: Discriminator of the controlled account
• scope: Array of group whitelist/blacklists to apply (if both white- and blacklists are present, then blacklist is subtracted from the whitelist)
• controller: The user who controls the account (implicit in writes, returned in reads of the controlled user)
• rights: Initial rights of the user

Returns: If unauthorized to create a controlled user or apply one or more of the control flags, return 403 Forbidden.
Otherwise, return 200 OK.

Delete controlled account: This endpoint shall remove a controlled user account. Anticensor provides two deletion methods:

POST /users/:id/delete - Regular invalidate & delete (like POST /users/@me/delete, but acting on others)

• Obeys retention policies
• Requires ACCOUNT_CONTROLLER or MANAGE_USERS permissions
• Permissions: A user with ACCOUNT_CONTROLLER can only delete an account within its own control group. A user with MANAGE_USERS can delete any user.

DELETE /users/:id - Right-to-erasure route (like DELETE /users/@me, but acting on others)

• Deletes everything created by the user
• Requires ACCOUNT_CONTROLLER or MANAGE_USERS permissions
• Permissions: A user with ACCOUNT_CONTROLLER can only delete an account within its own control group. A user with MANAGE_USERS can delete any user.

Returns: If the user does not exist, return 400 Bad Request. If the requesting user does not have the permission, then return 403 Forbidden.

Group white- and blacklist objects:
Parameters:

• whitelist: if true, a whitelist, else, a blacklist
• guilds: list of guilds
• users: list of DM targets
• roles: list of roles

If unauthorized to create a controlled user or apply one or more of the control flags, return 403 Forbidden.
On success, return 200 OK.

Group whitelist/blacklist create:

• users: Array of user IDs to be affected initially
• scope: Group whitelist/blacklist object

If unauthorized to create a controlled user or apply one or more of the control flags, return 403 Forbidden.
On success, return 200 OK.

Discriminator range reserve: Reserve certain discriminators for a certain account controller. An account controller can only reserve discriminators for itself, not for other controllers.
Parameters:

• include: a pair of discriminators, which denote an inclusive range
• exclude: array of pairs of discriminators, which denote ranges to be excluded from above

If unauthorized to create a controlled user or apply one or more of the control flags, return 403 Forbidden.
On success, return 200 OK.

Discriminator range fetch: Returns the reservation by reservation ID. Discriminator range reservations shall be returnable by any user.

If unauthorized to create the reservation or attempts to re-reserve an already reserved range, return 403 Forbidden.
On success, return 200 OK.

Discriminator range delete: Deletes the reservation by reservation ID. Only the user that created the reservation can delete it.

If unauthorized to unreserve the range, return 403 Forbidden. On attempt to delete a non-existent reservation, return 400 Bad Request.
On success, return 200 OK.

I have created the following plan after thorough exploration and analysis of the codebase. Follow the below plan verbatim. Trust the files and references. Do not re-verify what's written in the plan. Explore only when absolutely necessary. First implement all the proposed file changes and then I'll review all the changes together at the end.

### Summary

# Controlled Accounts Implementation Plan

Based on my analysis of the Spacebar codebase (a Discord-like server implementation), I'll provide a comprehensive implementation plan for the controlled accounts feature as described in the GitHub ticket.

## Overview

The controlled accounts feature enables parental/organizational control over user accounts through:
- **Controlled User Management**: Create and manage accounts under supervision
- **Whitelist/Blacklist Groups**: Control access to guilds, users, and roles
- **Discriminator Reservations**: Reserve discriminator ranges for controlled accounts
- **Acting on Behalf**: Perform actions as controlled users
- **Comprehensive API**: Full CRUD operations for all components

## Architecture Analysis

The Spacebar codebase follows these patterns that we'll leverage:

### Current Structure
- **Entity System**: TypeORM entities in `src/util/entities/`
- **Rights System**: BitField-based permissions in `src/util/util/Rights.ts`
- **Authentication**: JWT tokens with middleware in `src/api/middlewares/Authentication.ts`
- **API Routes**: RESTful endpoints under `src/api/routes/`
- **Validation**: Request/response schemas in `src/util/schemas/`
- **Database**: Multi-engine support (PostgreSQL, MySQL, MariaDB)

### Key Integration Points
- **User Entity**: Existing user management with rights, discriminators, and relationships
- **Route Handler**: Standardized `route()` helper with rights checking
- **Token System**: JWT-based authentication with user validation
- **Migration System**: Database schema versioning across multiple engines

## Implementation Strategy

### 1. Database Layer (New Entities)

#### ControlledAccount Entity
```typescript
// src/util/entities/ControlledAccount.ts
@Entity({ name: "controlled_accounts" })
export class ControlledAccount extends BaseClass {
  @Column()
  controller_id: string; // Foreign key to controlling User
  
  @Column()
  controlled_id: string; // Foreign key to controlled User
  
  @Column({ type: "simple-array", nullable: true })
  scope?: string[]; // Array of whitelist/blacklist group IDs
  
  @Column({ type: "bigint", nullable: true })
  rights?: string; // Initial rights override
  
  @ManyToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "controller_id" })
  controller: User;
  
  @OneToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "controlled_id" })
  controlled: User;
}

WhitelistBlacklistGroup Entity

// src/util/entities/WhitelistBlacklistGroup.ts
@Entity({ name: "whitelist_blacklist_groups" })
export class WhitelistBlacklistGroup extends BaseClass {
  @Column()
  owner_id: string; // Foreign key to User who created the group
  
  @Column()
  name: string; // Descriptive name
  
  @Column()
  whitelist: boolean; // true = whitelist, false = blacklist
  
  @Column({ type: "simple-array", nullable: true })
  guilds?: string[]; // Guild IDs
  
  @Column({ type: "simple-array", nullable: true })
  users?: string[]; // DM target user IDs
  
  @Column({ type: "simple-array", nullable: true })
  roles?: string[]; // Role IDs
  
  @ManyToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "owner_id" })
  owner: User;
}

DiscriminatorReservation Entity

// src/util/entities/DiscriminatorReservation.ts
@Entity({ name: "discriminator_reservations" })
export class DiscriminatorReservation extends BaseClass {
  @Column()
  reserved_by: string; // Foreign key to User
  
  @Column()
  include_start: string; // Start of inclusive range
  
  @Column()
  include_end: string; // End of inclusive range
  
  @Column({ type: "simple-json", nullable: true })
  exclude_ranges?: [string, string][]; // Excluded ranges
  
  @Column({ nullable: true })
  expires_at?: Date; // Optional expiration
  
  @ManyToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "reserved_by" })
  user: User;
}

2. Rights System Extension

Add new rights flags to src/util/util/Rights.ts:

static FLAGS = {
  // ... existing flags ...
  ACCOUNT_CONTROLLER: BitFlag(51),        // Can create and manage controlled accounts
  CREATE_CONTROLLED_ACCOUNTS: BitFlag(52), // Can create controlled accounts
  MANAGE_CONTROLLED_ACCOUNTS: BitFlag(53), // Can manage controlled accounts
  ACT_AS_CONTROLLED: BitFlag(54),         // Can perform actions on behalf
  RESERVE_DISCRIMINATORS: BitFlag(55),    // Can reserve discriminator ranges
  MANAGE_WHITELIST_GROUPS: BitFlag(56),   // Can create/manage whitelist groups
};

3. Authentication Enhancement

Token System Updates (src/util/util/Token.ts)

export type UserTokenData = {
  user: User;
  decoded: { 
    id: string; 
    iat: number; 
    email?: string;
    acting_as?: string; // ID of controlled account being acted as
  };
};

export async function generateActingToken(
  controller_id: string, 
  controlled_id: string
): Promise<string> {
  // Generate token with acting_as field for controlled account actions
}

Authentication Middleware Updates (src/api/middlewares/Authentication.ts)

declare global {
  namespace Express {
    interface Request {
      user_id: string;
      user_bot: boolean;
      token: { id: string; iat: number };
      rights: Rights;
      acting_user_id?: string;    // ID of controlled account being acted as
      controller_id?: string;     // ID of actual controlling user
    }
  }
}

4. User Entity Integration

Extend src/util/entities/User.ts:

export class User extends BaseClass {
  // ... existing fields ...
  
  @OneToMany(() => ControlledAccount, (ca) => ca.controller)
  controlled_accounts: ControlledAccount[];
  
  @OneToOne(() => ControlledAccount, (ca) => ca.controlled)
  controller_relationship: ControlledAccount;
  
  @OneToMany(() => WhitelistBlacklistGroup, (group) => group.owner)
  whitelist_groups: WhitelistBlacklistGroup[];
  
  // Helper methods
  isControlledAccount(): boolean {
    return !!this.controller_relationship;
  }
  
  async getController(): Promise<User | null> {
    if (!this.controller_relationship) return null;
    return this.controller_relationship.controller;
  }
  
  // Enhanced discriminator generation with reservation checking
  public static async generateDiscriminator(
    username: string,
    checkReservations: boolean = true
  ): Promise<string | undefined> {
    // Existing logic + reservation checking
  }
}

5. API Routes Structure

Create comprehensive admin routes under src/api/routes/admin/:

src/api/routes/admin/
├── groups/
│   ├── index.ts                    # POST /admin/groups, GET /admin/groups
│   └── #group_id/
│       └── index.ts               # GET/PATCH/DELETE /admin/groups/:id
├── controlled-accounts/
│   ├── index.ts                   # POST /admin/controlled-accounts, GET /admin/controlled-accounts
│   └── #account_id/
│       ├── index.ts              # GET/DELETE/PATCH /admin/controlled-accounts/:id
│       └── token.ts              # POST /admin/controlled-accounts/:id/token
└── discriminators/
    └── index.ts                   # POST /admin/discriminators/reserve, GET/DELETE /admin/discriminators/:id

6. Validation Schemas

Create request/response schemas in src/util/schemas/:

Group Management

// WhitelistBlacklistGroupCreateSchema.ts
export interface WhitelistBlacklistGroupCreateSchema {
  name: string;
  whitelist: boolean;
  guilds?: string[];
  users?: string[];
  roles?: string[];
}

Controlled Account Management

// ControlledAccountCreateSchema.ts
export interface ControlledAccountCreateSchema {
  username: string;
  tag?: string;           // Optional discriminator
  scope?: string[];       // Group whitelist/blacklist IDs
  rights?: string;        // Initial rights
}

Discriminator Reservations

// DiscriminatorReserveSchema.ts
export interface DiscriminatorRangeReserveSchema {
  include: [string, string];        // Inclusive range
  exclude?: [string, string][];     // Excluded ranges
}

7. Database Migrations

Create migrations for all supported database engines:

• src/util/migration/postgres/1756362750953-ControlledAccounts.ts
• src/util/migration/mysql/1756362750953-ControlledAccounts.ts
• src/util/migration/mariadb/1756362750953-ControlledAccounts.ts

Each migration will create:

• controlled_accounts table with proper foreign keys
• whitelist_blacklist_groups table with owner relationships
• discriminator_reservations table with range management
• Appropriate indexes for performance

Key API Endpoints

Group Management

• POST /admin/groups - Create whitelist/blacklist group
• GET /admin/groups - List user's groups
• GET /admin/groups/:id - Get specific group
• PATCH /admin/groups/:id - Update group
• DELETE /admin/groups/:id - Delete group

Controlled Account Management

• POST /admin/controlled-accounts - Create controlled account
• GET /admin/controlled-accounts - List controlled accounts
• GET /admin/controlled-accounts/:id - Get controlled account details
• DELETE /admin/controlled-accounts/:id - Delete controlled account
• PATCH /admin/controlled-accounts/:id/scope - Apply group restrictions
• POST /admin/controlled-accounts/:id/token - Generate acting token

Discriminator Management

• POST /admin/discriminators/reserve - Reserve discriminator range
• GET /admin/discriminators/:id - Fetch reservation details
• DELETE /admin/discriminators/:id - Delete reservation

User Deletion (Enhanced)

• POST /users/:id/delete - Regular deletion with retention policies
• DELETE /users/:id - Right-to-erasure deletion

Security Considerations

Rights-Based Access Control

• All operations require appropriate rights flags
• Controllers can only manage their own controlled accounts
• Discriminator reservations are user-specific
• Acting tokens include both controller and controlled user context

Validation and Error Handling

• Comprehensive input validation using existing schema system
• Proper error codes (400, 403, 404) as specified in ticket
• Cascade deletion for data consistency
• Token validation for acting-on-behalf functionality

Integration Benefits

Seamless Integration

• Leverages existing User entity and rights system
• Uses established route handler patterns with rights checking
• Follows existing authentication and token patterns
• Maintains database compatibility across all supported engines

Extensibility

• Modular design allows for future enhancements
• Rights system can be extended for additional permissions
• Group system supports complex whitelist/blacklist combinations
• Discriminator reservation system supports flexible range management

This implementation provides a comprehensive controlled accounts system that integrates seamlessly with the existing Spacebar architecture while meeting all requirements specified in the GitHub ticket.

[traycerai]

I have updated the Implementation Plan to reflect the recent changes in the ticket.

Previous Plan

Observations

The codebase is a Discord-like server implementation with a comprehensive user management system. It uses TypeORM entities, JWT authentication, a BitField-based rights system, and follows REST API patterns. The existing User entity has rights management, discriminator generation, and admin capabilities through the MANAGE_USERS right. There's no existing controlled accounts system, but the foundation exists with user rights, authentication middleware, and admin routes patterns.

Approach

I'll implement the controlled accounts feature by:

1. Database Layer: Create new entities for controlled accounts and whitelist/blacklist groups with proper relations
2. Rights System: Add new rights flags for controlled account management
3. Authentication: Extend JWT tokens and middleware to support "acting on behalf" functionality
4. API Routes: Create comprehensive REST endpoints for group management, controlled account CRUD, and proxy actions
5. Validation: Add request/response schemas following existing patterns
6. Discriminator Management: Extend existing discriminator logic for reservation/unreservation

The implementation follows the existing codebase patterns and integrates seamlessly with the current user management system.

Reasoning

I explored the codebase structure to understand the Discord-like server implementation. I examined the User entity and rights system to understand existing user management. I analyzed the authentication middleware and JWT token system to understand how to implement "acting on behalf" functionality. I reviewed existing API routes and schemas to follow established patterns. I checked the discriminator generation logic and found admin route examples to understand the current architecture.

Proposed File Changes

📄 src/util/entities/ControlledAccount.ts ^(NEW) 🔗

References

• 📄 src/util/entities/User.ts ^(MODIFY)
• 📄 src/util/entities/BaseClass.ts

Create a new TypeORM entity to represent the relationship between controllers and controlled accounts. This entity will include:

• id (primary key)
• controller_id (foreign key to User)
• controlled_id (foreign key to User)
• created_at timestamp
• scope (array of group whitelist/blacklist IDs to apply)
• rights (initial rights override for the controlled user)

Include proper TypeORM decorators, relations to the User entity, and validation methods. This follows the same pattern as other entities in src/util/entities/.

📄 src/util/entities/WhitelistBlacklistGroup.ts ^(NEW) 🔗

References

• 📄 src/util/entities/User.ts ^(MODIFY)
• 📄 src/util/entities/BaseClass.ts

Create a new TypeORM entity for whitelist/blacklist groups. This entity will include:

• id (primary key)
• owner_id (foreign key to User who created the group)
• name (descriptive name for the group)
• whitelist (array of guild IDs and DM target user IDs)
• blacklist (array of guild IDs and DM target user IDs to subtract from whitelist)
• created_at and updated_at timestamps

Include proper TypeORM decorators, relations to the User entity, and methods for resolving effective permissions (whitelist minus blacklist). This follows the same pattern as other entities in src/util/entities/.

📄 src/util/entities/DiscriminatorReservation.ts ^(NEW) 🔗

References

• 📄 src/util/entities/User.ts ^(MODIFY)
• 📄 src/util/entities/BaseClass.ts

Create a new TypeORM entity to track discriminator reservations. This entity will include:

• id (primary key)
• username (the username for which discriminators are reserved)
• discriminator_start (start of reserved range)
• discriminator_end (end of reserved range)
• reserved_by (foreign key to User who made the reservation)
• created_at timestamp
• expires_at (optional expiration)

Include methods for checking if a discriminator is reserved and for cleaning up expired reservations. This supports the discriminator step-reserve and range unreserve functionality mentioned in the ticket.

📄 src/util/entities/User.ts ^(MODIFY) 🔗

References

• 📄 src/util/entities/ControlledAccount.ts ^(NEW)
• 📄 src/util/entities/WhitelistBlacklistGroup.ts ^(NEW)
• 📄 src/util/entities/DiscriminatorReservation.ts ^(NEW)

Add new relations to the User entity to support controlled accounts:

• Add @OneToMany relation to ControlledAccount for accounts this user controls
• Add @OneToOne relation to ControlledAccount for when this user is controlled by another
• Add @OneToMany relation to WhitelistBlacklistGroup for groups owned by this user

Also add helper methods:

• isControlledAccount() - returns boolean if this user is controlled
• getController() - returns the controlling user if this is a controlled account
• getControlledAccounts() - returns array of accounts controlled by this user

These additions integrate with the existing User entity structure and follow the same patterns used for other relations like relationships and connected_accounts.
Extend the generateDiscriminator method to check for reservations:

1. Before generating a discriminator, query DiscriminatorReservation to check if the discriminator is reserved
2. Skip reserved discriminators when generating random or incremental discriminators
3. Add helper method isDiscriminatorReserved(username: string, discriminator: string): Promise<boolean>
4. Add cleanup method cleanupExpiredReservations(): Promise<void> to remove expired reservations

This integrates the discriminator reservation system with the existing discriminator generation logic, ensuring reserved discriminators are not assigned to regular users.

📄 src/util/entities/index.ts ^(MODIFY) 🔗

References

• 📄 src/util/entities/ControlledAccount.ts ^(NEW)
• 📄 src/util/entities/WhitelistBlacklistGroup.ts ^(NEW)
• 📄 src/util/entities/DiscriminatorReservation.ts ^(NEW)

Add exports for the new entities:

export * from "./ControlledAccount";
export * from "./WhitelistBlacklistGroup";
export * from "./DiscriminatorReservation";

This follows the existing pattern in the index file where all entities are exported for easy importing throughout the codebase.

📄 src/util/util/Rights.ts ^(MODIFY) 🔗

References

• 📄 src/api/util/handlers/route.ts

Add new rights flags to the Rights.FLAGS object for controlled account management:

• CREATE_CONTROLLED_ACCOUNTS: BitFlag(51) - can create controlled user accounts
• MANAGE_CONTROLLED_ACCOUNTS: BitFlag(52) - can manage controlled accounts (delete, modify scope)
• ACT_AS_CONTROLLED: BitFlag(53) - can perform actions on behalf of controlled accounts
• RESERVE_DISCRIMINATORS: BitFlag(54) - can reserve discriminator ranges
• MANAGE_WHITELIST_GROUPS: BitFlag(55) - can create and manage whitelist/blacklist groups

These new rights integrate with the existing rights system and follow the same BitFlag pattern used for other permissions. The rights will be checked in route handlers using the existing right: "RIGHT_NAME" pattern in the route() helper function.

📄 src/util/util/Token.ts ^(MODIFY) 🔗

References

• 📄 src/api/middlewares/Authentication.ts ^(MODIFY)

Extend the JWT token system to support "acting on behalf" functionality:

1. Update the UserTokenData type to include optional acting_as field
2. Modify generateToken function to accept optional acting_as parameter
3. Update checkToken function to validate and return acting_as information
4. Add new function generateActingToken(controller_id: string, controlled_id: string) that creates tokens for controlled account actions

The token payload will include both the controller's ID (as id) and the controlled account's ID (as acting_as). This allows the authentication middleware to properly identify both the actual user and the account they're acting as, similar to how src/api/middlewares/Authentication.ts currently handles user identification.

📄 src/api/middlewares/Authentication.ts ^(MODIFY) 🔗

References

• 📄 src/util/util/Token.ts ^(MODIFY)
• 📄 src/util/entities/ControlledAccount.ts ^(NEW)

Extend the authentication middleware to support controlled accounts:

1. Add new fields to the Express Request interface:

   • acting_user_id?: string - ID of the controlled account being acted as
   • controller_id?: string - ID of the actual controlling user

2. Modify the authentication logic to handle acting tokens:

   • When a token contains acting_as, validate that the controller has ACT_AS_CONTROLLED right
   • Verify the controlled account relationship exists in the database
   • Set both req.user_id (controlled account) and req.controller_id (actual user)
   • Load rights from the controlled account, not the controller

3. Add helper function isActingAsControlled(req: Request): boolean

This extends the existing authentication flow in src/api/middlewares/Authentication.ts while maintaining backward compatibility with regular user tokens.

📄 src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts ^(NEW) 🔗

References

• 📄 src/util/schemas/RegisterSchema.ts

Create a validation schema for creating whitelist/blacklist groups:

export interface WhitelistBlacklistGroupCreateSchema {
  name: string; // descriptive name for the group
  whitelist: string[]; // array of guild IDs and DM target user IDs
  blacklist?: string[]; // optional array to subtract from whitelist
}

This follows the same pattern as other schemas in src/util/schemas/ like RegisterSchema.ts and includes proper TypeScript interfaces with JSDoc annotations for validation.

📄 src/util/schemas/WhitelistBlacklistGroupModifySchema.ts ^(NEW) 🔗

References

• 📄 src/util/schemas/UserModifySchema.ts

Create a validation schema for modifying whitelist/blacklist groups:

export interface WhitelistBlacklistGroupModifySchema {
  name?: string;
  whitelist?: string[];
  blacklist?: string[];
}

This allows partial updates to groups, following the same pattern as UserModifySchema.ts where all fields are optional.

📄 src/util/schemas/ControlledAccountCreateSchema.ts ^(NEW) 🔗

References

• 📄 src/util/schemas/RegisterSchema.ts

Create a validation schema for creating controlled accounts based on the ticket requirements:

export interface ControlledAccountCreateSchema {
  username: string; // name of the controlled account
  tag?: string; // discriminator (optional, will be generated if not provided)
  scope?: string[]; // array of group whitelist/blacklist IDs to apply
  rights?: string; // initial rights of the user (as string to match User entity)
}

Note that controller is implicit (the authenticated user making the request) as mentioned in the ticket. This schema follows the same pattern as RegisterSchema.ts but is tailored for controlled account creation.

📄 src/util/schemas/DiscriminatorReserveSchema.ts ^(NEW) 🔗

References

• 📄 src/util/entities/DiscriminatorReservation.ts ^(NEW)

Create validation schemas for discriminator reservation operations:

export interface DiscriminatorStepReserveSchema {
  username: string;
  discriminator: string; // specific discriminator to reserve
  expires_at?: Date; // optional expiration
}

export interface DiscriminatorRangeUnreserveSchema {
  username: string;
  discriminator_start: string;
  discriminator_end: string;
}

These schemas support the discriminator step-reserve and range unreserve functionality mentioned in the ticket.

📄 src/util/schemas/index.ts ^(MODIFY) 🔗

References

• 📄 src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts ^(NEW)
• 📄 src/util/schemas/WhitelistBlacklistGroupModifySchema.ts ^(NEW)
• 📄 src/util/schemas/ControlledAccountCreateSchema.ts ^(NEW)
• 📄 src/util/schemas/DiscriminatorReserveSchema.ts ^(NEW)

Add exports for all the new schemas:

export * from "./WhitelistBlacklistGroupCreateSchema";
export * from "./WhitelistBlacklistGroupModifySchema";
export * from "./ControlledAccountCreateSchema";
export * from "./DiscriminatorReserveSchema";

This follows the existing pattern in the schemas index file for easy importing throughout the codebase.

I have created the following plan after thorough exploration and analysis of the codebase. Follow the below plan verbatim. Trust the files and references. Do not re-verify what's written in the plan. Explore only when absolutely necessary. First implement all the proposed file changes and then I'll review all the changes together at the end.

### Observations

The codebase is a Discord-like server implementation with a comprehensive user management system. It uses TypeORM entities, JWT authentication, a BitField-based rights system, and follows REST API patterns. The existing User entity has rights management, discriminator generation, and admin capabilities through the `MANAGE_USERS` right. There's no existing controlled accounts system, but the foundation exists with user rights, authentication middleware, and admin routes patterns.

### Approach

I'll implement the controlled accounts feature by:

1. **Database Layer**: Create new entities for controlled accounts and whitelist/blacklist groups with proper relations
2. **Rights System**: Add new rights flags for controlled account management 
3. **Authentication**: Extend JWT tokens and middleware to support "acting on behalf" functionality
4. **API Routes**: Create comprehensive REST endpoints for group management, controlled account CRUD, and proxy actions
5. **Validation**: Add request/response schemas following existing patterns
6. **Discriminator Management**: Extend existing discriminator logic for reservation/unreservation

The implementation follows the existing codebase patterns and integrates seamlessly with the current user management system.

### Reasoning

I explored the codebase structure to understand the Discord-like server implementation. I examined the User entity and rights system to understand existing user management. I analyzed the authentication middleware and JWT token system to understand how to implement "acting on behalf" functionality. I reviewed existing API routes and schemas to follow established patterns. I checked the discriminator generation logic and found admin route examples to understand the current architecture.

## Proposed File Changes

### src/util/entities/ControlledAccount.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity to represent the relationship between controllers and controlled accounts. This entity will include:

- `id` (primary key)
- `controller_id` (foreign key to User)
- `controlled_id` (foreign key to User) 
- `created_at` timestamp
- `scope` (array of group whitelist/blacklist IDs to apply)
- `rights` (initial rights override for the controlled user)

Include proper TypeORM decorators, relations to the `User` entity, and validation methods. This follows the same pattern as other entities in `src/util/entities/`.

### src/util/entities/WhitelistBlacklistGroup.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity for whitelist/blacklist groups. This entity will include:

- `id` (primary key)
- `owner_id` (foreign key to User who created the group)
- `name` (descriptive name for the group)
- `whitelist` (array of guild IDs and DM target user IDs)
- `blacklist` (array of guild IDs and DM target user IDs to subtract from whitelist)
- `created_at` and `updated_at` timestamps

Include proper TypeORM decorators, relations to the `User` entity, and methods for resolving effective permissions (whitelist minus blacklist). This follows the same pattern as other entities in `src/util/entities/`.

### src/util/entities/DiscriminatorReservation.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity to track discriminator reservations. This entity will include:

- `id` (primary key)
- `username` (the username for which discriminators are reserved)
- `discriminator_start` (start of reserved range)
- `discriminator_end` (end of reserved range)
- `reserved_by` (foreign key to User who made the reservation)
- `created_at` timestamp
- `expires_at` (optional expiration)

Include methods for checking if a discriminator is reserved and for cleaning up expired reservations. This supports the discriminator step-reserve and range unreserve functionality mentioned in the ticket.

### src/util/entities/User.ts(MODIFY)

References: 

- src/util/entities/ControlledAccount.ts(NEW)
- src/util/entities/WhitelistBlacklistGroup.ts(NEW)
- src/util/entities/DiscriminatorReservation.ts(NEW)

Add new relations to the User entity to support controlled accounts:

- Add `@OneToMany` relation to `ControlledAccount` for accounts this user controls
- Add `@OneToOne` relation to `ControlledAccount` for when this user is controlled by another
- Add `@OneToMany` relation to `WhitelistBlacklistGroup` for groups owned by this user

Also add helper methods:
- `isControlledAccount()` - returns boolean if this user is controlled
- `getController()` - returns the controlling user if this is a controlled account
- `getControlledAccounts()` - returns array of accounts controlled by this user

These additions integrate with the existing User entity structure and follow the same patterns used for other relations like `relationships` and `connected_accounts`.
Extend the `generateDiscriminator` method to check for reservations:

1. Before generating a discriminator, query `DiscriminatorReservation` to check if the discriminator is reserved
2. Skip reserved discriminators when generating random or incremental discriminators
3. Add helper method `isDiscriminatorReserved(username: string, discriminator: string): Promise<boolean>`
4. Add cleanup method `cleanupExpiredReservations(): Promise<void>` to remove expired reservations

This integrates the discriminator reservation system with the existing discriminator generation logic, ensuring reserved discriminators are not assigned to regular users.

### src/util/entities/index.ts(MODIFY)

References: 

- src/util/entities/ControlledAccount.ts(NEW)
- src/util/entities/WhitelistBlacklistGroup.ts(NEW)
- src/util/entities/DiscriminatorReservation.ts(NEW)

Add exports for the new entities:

```typescript
export * from "./ControlledAccount";
export * from "./WhitelistBlacklistGroup";
export * from "./DiscriminatorReservation";

This follows the existing pattern in the index file where all entities are exported for easy importing throughout the codebase.

src/util/util/Rights.ts(MODIFY)

References:

• src/api/util/handlers/route.ts

Add new rights flags to the Rights.FLAGS object for controlled account management:

• CREATE_CONTROLLED_ACCOUNTS: BitFlag(51) - can create controlled user accounts
• MANAGE_CONTROLLED_ACCOUNTS: BitFlag(52) - can manage controlled accounts (delete, modify scope)
• ACT_AS_CONTROLLED: BitFlag(53) - can perform actions on behalf of controlled accounts
• RESERVE_DISCRIMINATORS: BitFlag(54) - can reserve discriminator ranges
• MANAGE_WHITELIST_GROUPS: BitFlag(55) - can create and manage whitelist/blacklist groups

These new rights integrate with the existing rights system and follow the same BitFlag pattern used for other permissions. The rights will be checked in route handlers using the existing right: "RIGHT_NAME" pattern in the route() helper function.

src/util/util/Token.ts(MODIFY)

References:

• src/api/middlewares/Authentication.ts(MODIFY)

Extend the JWT token system to support "acting on behalf" functionality:

1. Update the UserTokenData type to include optional acting_as field
2. Modify generateToken function to accept optional acting_as parameter
3. Update checkToken function to validate and return acting_as information
4. Add new function generateActingToken(controller_id: string, controlled_id: string) that creates tokens for controlled account actions

The token payload will include both the controller's ID (as id) and the controlled account's ID (as acting_as). This allows the authentication middleware to properly identify both the actual user and the account they're acting as, similar to how src/api/middlewares/Authentication.ts currently handles user identification.

src/api/middlewares/Authentication.ts(MODIFY)

References:

• src/util/util/Token.ts(MODIFY)
• src/util/entities/ControlledAccount.ts(NEW)

Extend the authentication middleware to support controlled accounts:

1. Add new fields to the Express Request interface:

   • acting_user_id?: string - ID of the controlled account being acted as
   • controller_id?: string - ID of the actual controlling user

2. Modify the authentication logic to handle acting tokens:

   • When a token contains acting_as, validate that the controller has ACT_AS_CONTROLLED right
   • Verify the controlled account relationship exists in the database
   • Set both req.user_id (controlled account) and req.controller_id (actual user)
   • Load rights from the controlled account, not the controller

3. Add helper function isActingAsControlled(req: Request): boolean

This extends the existing authentication flow in src/api/middlewares/Authentication.ts while maintaining backward compatibility with regular user tokens.

src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts(NEW)

References:

• src/util/schemas/RegisterSchema.ts

Create a validation schema for creating whitelist/blacklist groups:

export interface WhitelistBlacklistGroupCreateSchema {
  name: string; // descriptive name for the group
  whitelist: string[]; // array of guild IDs and DM target user IDs
  blacklist?: string[]; // optional array to subtract from whitelist
}

This follows the same pattern as other schemas in src/util/schemas/ like RegisterSchema.ts and includes proper TypeScript interfaces with JSDoc annotations for validation.

src/util/schemas/WhitelistBlacklistGroupModifySchema.ts(NEW)

References:

• src/util/schemas/UserModifySchema.ts

Create a validation schema for modifying whitelist/blacklist groups:

export interface WhitelistBlacklistGroupModifySchema {
  name?: string;
  whitelist?: string[];
  blacklist?: string[];
}

This allows partial updates to groups, following the same pattern as UserModifySchema.ts where all fields are optional.

src/util/schemas/ControlledAccountCreateSchema.ts(NEW)

References:

• src/util/schemas/RegisterSchema.ts

Create a validation schema for creating controlled accounts based on the ticket requirements:

export interface ControlledAccountCreateSchema {
  username: string; // name of the controlled account
  tag?: string; // discriminator (optional, will be generated if not provided)
  scope?: string[]; // array of group whitelist/blacklist IDs to apply
  rights?: string; // initial rights of the user (as string to match User entity)
}

Note that controller is implicit (the authenticated user making the request) as mentioned in the ticket. This schema follows the same pattern as RegisterSchema.ts but is tailored for controlled account creation.

src/util/schemas/DiscriminatorReserveSchema.ts(NEW)

References:

• src/util/entities/DiscriminatorReservation.ts(NEW)

Create validation schemas for discriminator reservation operations:

export interface DiscriminatorStepReserveSchema {
  username: string;
  discriminator: string; // specific discriminator to reserve
  expires_at?: Date; // optional expiration
}

export interface DiscriminatorRangeUnreserveSchema {
  username: string;
  discriminator_start: string;
  discriminator_end: string;
}

These schemas support the discriminator step-reserve and range unreserve functionality mentioned in the ticket.

src/util/schemas/index.ts(MODIFY)

References:

• src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts(NEW)
• src/util/schemas/WhitelistBlacklistGroupModifySchema.ts(NEW)
• src/util/schemas/ControlledAccountCreateSchema.ts(NEW)
• src/util/schemas/DiscriminatorReserveSchema.ts(NEW)

Add exports for all the new schemas:

export * from "./WhitelistBlacklistGroupCreateSchema";
export * from "./WhitelistBlacklistGroupModifySchema";
export * from "./ControlledAccountCreateSchema";
export * from "./DiscriminatorReserveSchema";

This follows the existing pattern in the schemas index file for easy importing throughout the codebase.

   • Uses DiscriminatorRangeUnreserveSchema for validation
   • Removes DiscriminatorReservation records in the specified range
   • Returns 204 No Content

This implements the discriminator step-reserve and range unreserve functionality mentioned in the ticket.

src/util/migration/postgres/1756362750953-ControlledAccounts.ts(NEW)

References:

• src/util/migration/postgres/1720628601997-badges.ts

Create PostgreSQL migration for the controlled accounts feature:

1. Create controlled_accounts table with proper foreign keys to users
2. Create whitelist_blacklist_groups table with owner relationship
3. Create discriminator_reservations table for discriminator management
4. Add proper indexes for performance (controller_id, controlled_id, owner_id, username+discriminator)
5. Add foreign key constraints with CASCADE delete behavior

This follows the same pattern as existing migrations in src/util/migration/postgres/ and ensures database schema supports all the new entities.

src/util/migration/mysql/1756362750953-ControlledAccounts.ts(NEW)

<summary>New Plan</summary>



### Observations

The codebase is a comprehensive Discord-like server implementation called "Spacebar" with a robust user management system. It uses TypeORM entities, JWT authentication, a BitField-based rights system, and follows REST API patterns. The existing User entity has rights management, discriminator generation, and comprehensive user features. There's no existing controlled accounts system, but the foundation exists with user rights, authentication middleware, and established route patterns. The ticket requests a complex feature for parental/organizational control over user accounts.

### Approach

I'll implement the controlled accounts feature by:

1. **Database Layer**: Create new entities for controlled accounts, whitelist/blacklist groups, and discriminator reservations with proper TypeORM relations
2. **Rights System**: Add new rights flags for controlled account management following the existing BitField pattern
3. **Authentication**: Extend JWT tokens and middleware to support "acting on behalf" functionality
4. **API Routes**: Create comprehensive REST endpoints under `/admin/` for group management, controlled account CRUD, discriminator reservations, and proxy actions
5. **Validation**: Add request/response schemas following existing patterns in `src/util/schemas/`
6. **Database Migrations**: Create migrations for all supported database engines (PostgreSQL, MySQL, MariaDB)

The implementation follows the existing codebase patterns and integrates seamlessly with the current user management system.

### Reasoning

I explored the codebase structure to understand this Discord-like server implementation. I examined the User entity and rights system to understand existing user management patterns. I analyzed the authentication middleware and JWT token system to understand how to implement "acting on behalf" functionality. I reviewed existing API routes and schemas to follow established patterns. I checked the discriminator generation logic and found the route handler patterns to understand the current architecture.

```markdown
I have created the following plan after thorough exploration and analysis of the codebase. Follow the below plan verbatim. Trust the files and references. Do not re-verify what's written in the plan. Explore only when absolutely necessary. First implement all the proposed file changes and then I'll review all the changes together at the end.

### Observations

The codebase is a comprehensive Discord-like server implementation called "Spacebar" with a robust user management system. It uses TypeORM entities, JWT authentication, a BitField-based rights system, and follows REST API patterns. The existing User entity has rights management, discriminator generation, and comprehensive user features. There's no existing controlled accounts system, but the foundation exists with user rights, authentication middleware, and established route patterns. The ticket requests a complex feature for parental/organizational control over user accounts.

### Approach

I'll implement the controlled accounts feature by:

1. **Database Layer**: Create new entities for controlled accounts, whitelist/blacklist groups, and discriminator reservations with proper TypeORM relations
2. **Rights System**: Add new rights flags for controlled account management following the existing BitField pattern
3. **Authentication**: Extend JWT tokens and middleware to support "acting on behalf" functionality
4. **API Routes**: Create comprehensive REST endpoints under `/admin/` for group management, controlled account CRUD, discriminator reservations, and proxy actions
5. **Validation**: Add request/response schemas following existing patterns in `src/util/schemas/`
6. **Database Migrations**: Create migrations for all supported database engines (PostgreSQL, MySQL, MariaDB)

The implementation follows the existing codebase patterns and integrates seamlessly with the current user management system.

### Reasoning

I explored the codebase structure to understand this Discord-like server implementation. I examined the User entity and rights system to understand existing user management patterns. I analyzed the authentication middleware and JWT token system to understand how to implement "acting on behalf" functionality. I reviewed existing API routes and schemas to follow established patterns. I checked the discriminator generation logic and found the route handler patterns to understand the current architecture.

## Proposed File Changes

### src/util/entities/ControlledAccount.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity to represent the relationship between controllers and controlled accounts. This entity will include:

- `id` (primary key)
- `controller_id` (foreign key to User)
- `controlled_id` (foreign key to User) 
- `created_at` timestamp
- `scope` (array of group whitelist/blacklist IDs to apply)
- `rights` (initial rights override for the controlled user)

Include proper TypeORM decorators, relations to the `User` entity from `src/util/entities/User.ts`, and validation methods. This follows the same pattern as other entities in `src/util/entities/`.

### src/util/entities/WhitelistBlacklistGroup.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity for whitelist/blacklist groups as specified in the ticket. This entity will include:

- `id` (primary key)
- `owner_id` (foreign key to User who created the group)
- `name` (descriptive name for the group)
- `whitelist` (boolean indicating if this is a whitelist or blacklist)
- `guilds` (array of guild IDs)
- `users` (array of DM target user IDs)
- `roles` (array of role IDs)
- `created_at` and `updated_at` timestamps

Include proper TypeORM decorators, relations to the `User` entity from `src/util/entities/User.ts`, and methods for resolving effective permissions. This follows the same pattern as other entities in `src/util/entities/`.

### src/util/entities/DiscriminatorReservation.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity to track discriminator reservations as mentioned in the ticket. This entity will include:

- `id` (primary key)
- `reserved_by` (foreign key to User who made the reservation)
- `include_start` and `include_end` (inclusive range of reserved discriminators)
- `exclude_ranges` (array of pairs representing excluded ranges)
- `created_at` timestamp
- `expires_at` (optional expiration)

Include methods for checking if a discriminator is reserved and for cleaning up expired reservations. This supports the discriminator range reserve and unreserve functionality mentioned in the ticket.

### src/util/entities/User.ts(MODIFY)

References: 

- src/util/entities/ControlledAccount.ts(NEW)
- src/util/entities/WhitelistBlacklistGroup.ts(NEW)
- src/util/entities/DiscriminatorReservation.ts(NEW)

Add new relations to the User entity to support controlled accounts:

- Add `@OneToMany` relation to `ControlledAccount` for accounts this user controls
- Add `@OneToOne` relation to `ControlledAccount` for when this user is controlled by another
- Add `@OneToMany` relation to `WhitelistBlacklistGroup` for groups owned by this user

Also add helper methods:
- `isControlledAccount()` - returns boolean if this user is controlled
- `getController()` - returns the controlling user if this is a controlled account
- `getControlledAccounts()` - returns array of accounts controlled by this user

Extend the `generateDiscriminator` method to check for reservations:
1. Before generating a discriminator, query `DiscriminatorReservation` to check if the discriminator is reserved
2. Skip reserved discriminators when generating random or incremental discriminators
3. Add helper method `isDiscriminatorReserved(username: string, discriminator: string): Promise<boolean>`
4. Add cleanup method `cleanupExpiredReservations(): Promise<void>` to remove expired reservations

These additions integrate with the existing User entity structure and follow the same patterns used for other relations like `relationships` and `connected_accounts`.

### src/util/entities/index.ts(MODIFY)

References: 

- src/util/entities/ControlledAccount.ts(NEW)
- src/util/entities/WhitelistBlacklistGroup.ts(NEW)
- src/util/entities/DiscriminatorReservation.ts(NEW)

Add exports for the new entities:

```typescript
export * from "./ControlledAccount";
export * from "./WhitelistBlacklistGroup";
export * from "./DiscriminatorReservation";

This follows the existing pattern in the index file where all entities are exported for easy importing throughout the codebase.

src/util/util/Rights.ts(MODIFY)

References:

• src/api/util/handlers/route.ts

Add new rights flags to the Rights.FLAGS object for controlled account management as mentioned in the ticket:

• ACCOUNT_CONTROLLER: BitFlag(51) - can create and manage controlled user accounts
• CREATE_CONTROLLED_ACCOUNTS: BitFlag(52) - can create controlled user accounts
• MANAGE_CONTROLLED_ACCOUNTS: BitFlag(53) - can manage controlled accounts (delete, modify scope)
• ACT_AS_CONTROLLED: BitFlag(54) - can perform actions on behalf of controlled accounts
• RESERVE_DISCRIMINATORS: BitFlag(55) - can reserve discriminator ranges
• MANAGE_WHITELIST_GROUPS: BitFlag(56) - can create and manage whitelist/blacklist groups

These new rights integrate with the existing rights system in src/util/util/Rights.ts and follow the same BitFlag pattern used for other permissions. The rights will be checked in route handlers using the existing right: "RIGHT_NAME" pattern in the route() helper function from src/api/util/handlers/route.ts.

src/util/util/Token.ts(MODIFY)

References:

• src/api/middlewares/Authentication.ts(MODIFY)

Extend the JWT token system to support "acting on behalf" functionality:

1. Update the UserTokenData type to include optional acting_as field
2. Modify generateToken function to accept optional acting_as parameter
3. Update checkToken function to validate and return acting_as information
4. Add new function generateActingToken(controller_id: string, controlled_id: string) that creates tokens for controlled account actions

The token payload will include both the controller's ID (as id) and the controlled account's ID (as acting_as). This allows the authentication middleware in src/api/middlewares/Authentication.ts to properly identify both the actual user and the account they're acting as.

src/api/middlewares/Authentication.ts(MODIFY)

References:

• src/util/util/Token.ts(MODIFY)
• src/util/entities/ControlledAccount.ts(NEW)
• src/util/util/Rights.ts(MODIFY)

Extend the authentication middleware to support controlled accounts:

1. Add new fields to the Express Request interface:

   • acting_user_id?: string - ID of the controlled account being acted as
   • controller_id?: string - ID of the actual controlling user

2. Modify the authentication logic to handle acting tokens:

   • When a token contains acting_as, validate that the controller has ACT_AS_CONTROLLED right
   • Verify the controlled account relationship exists in the database
   • Set both req.user_id (controlled account) and req.controller_id (actual user)
   • Load rights from the controlled account, not the controller

3. Add helper function isActingAsControlled(req: Request): boolean

This extends the existing authentication flow while maintaining backward compatibility with regular user tokens. The changes integrate with the existing authentication patterns and the Rights system from src/util/util/Rights.ts.

src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts(NEW)

References:

• src/util/schemas/RegisterSchema.ts

Create a validation schema for creating whitelist/blacklist groups based on the ticket specification:

export interface WhitelistBlacklistGroupCreateSchema {
  name: string; // descriptive name for the group

[traycerai]

I have updated the Implementation Plan to reflect the recent changes in the ticket.

Previous Plan

Observations

The codebase is a comprehensive Discord-like server implementation called "Spacebar" with a robust user management system. It uses TypeORM entities, JWT authentication, a BitField-based rights system, and follows REST API patterns. The existing User entity has rights management, discriminator generation, and comprehensive user features. There's no existing controlled accounts system, but the foundation exists with user rights, authentication middleware, and established route patterns. The ticket requests a complex feature for parental/organizational control over user accounts.

Approach

I'll implement the controlled accounts feature by:

1. Database Layer: Create new entities for controlled accounts, whitelist/blacklist groups, and discriminator reservations with proper TypeORM relations
2. Rights System: Add new rights flags for controlled account management following the existing BitField pattern
3. Authentication: Extend JWT tokens and middleware to support "acting on behalf" functionality
4. API Routes: Create comprehensive REST endpoints under /admin/ for group management, controlled account CRUD, discriminator reservations, and proxy actions
5. Validation: Add request/response schemas following existing patterns in src/util/schemas/
6. Database Migrations: Create migrations for all supported database engines (PostgreSQL, MySQL, MariaDB)

The implementation follows the existing codebase patterns and integrates seamlessly with the current user management system.

Reasoning

I explored the codebase structure to understand this Discord-like server implementation. I examined the User entity and rights system to understand existing user management patterns. I analyzed the authentication middleware and JWT token system to understand how to implement "acting on behalf" functionality. I reviewed existing API routes and schemas to follow established patterns. I checked the discriminator generation logic and found the route handler patterns to understand the current architecture.

Proposed File Changes

📄 src/util/entities/ControlledAccount.ts ^(NEW) 🔗

References

• 📄 src/util/entities/User.ts ^(MODIFY)
• 📄 src/util/entities/BaseClass.ts

Create a new TypeORM entity to represent the relationship between controllers and controlled accounts. This entity will include:

• id (primary key)
• controller_id (foreign key to User)
• controlled_id (foreign key to User)
• created_at timestamp
• scope (array of group whitelist/blacklist IDs to apply)
• rights (initial rights override for the controlled user)

Include proper TypeORM decorators, relations to the User entity from src/util/entities/User.ts, and validation methods. This follows the same pattern as other entities in src/util/entities/.

📄 src/util/entities/WhitelistBlacklistGroup.ts ^(NEW) 🔗

References

• 📄 src/util/entities/User.ts ^(MODIFY)
• 📄 src/util/entities/BaseClass.ts

Create a new TypeORM entity for whitelist/blacklist groups as specified in the ticket. This entity will include:

• id (primary key)
• owner_id (foreign key to User who created the group)
• name (descriptive name for the group)
• whitelist (boolean indicating if this is a whitelist or blacklist)
• guilds (array of guild IDs)
• users (array of DM target user IDs)
• roles (array of role IDs)
• created_at and updated_at timestamps

Include proper TypeORM decorators, relations to the User entity from src/util/entities/User.ts, and methods for resolving effective permissions. This follows the same pattern as other entities in src/util/entities/.

📄 src/util/entities/DiscriminatorReservation.ts ^(NEW) 🔗

References

• 📄 src/util/entities/User.ts ^(MODIFY)
• 📄 src/util/entities/BaseClass.ts

Create a new TypeORM entity to track discriminator reservations as mentioned in the ticket. This entity will include:

• id (primary key)
• reserved_by (foreign key to User who made the reservation)
• include_start and include_end (inclusive range of reserved discriminators)
• exclude_ranges (array of pairs representing excluded ranges)
• created_at timestamp
• expires_at (optional expiration)

Include methods for checking if a discriminator is reserved and for cleaning up expired reservations. This supports the discriminator range reserve and unreserve functionality mentioned in the ticket.

📄 src/util/entities/User.ts ^(MODIFY) 🔗

References

• 📄 src/util/entities/ControlledAccount.ts ^(NEW)
• 📄 src/util/entities/WhitelistBlacklistGroup.ts ^(NEW)
• 📄 src/util/entities/DiscriminatorReservation.ts ^(NEW)

Add new relations to the User entity to support controlled accounts:

• Add @OneToMany relation to ControlledAccount for accounts this user controls
• Add @OneToOne relation to ControlledAccount for when this user is controlled by another
• Add @OneToMany relation to WhitelistBlacklistGroup for groups owned by this user

Also add helper methods:

• isControlledAccount() - returns boolean if this user is controlled
• getController() - returns the controlling user if this is a controlled account
• getControlledAccounts() - returns array of accounts controlled by this user

Extend the generateDiscriminator method to check for reservations:

1. Before generating a discriminator, query DiscriminatorReservation to check if the discriminator is reserved
2. Skip reserved discriminators when generating random or incremental discriminators
3. Add helper method isDiscriminatorReserved(username: string, discriminator: string): Promise<boolean>
4. Add cleanup method cleanupExpiredReservations(): Promise<void> to remove expired reservations

These additions integrate with the existing User entity structure and follow the same patterns used for other relations like relationships and connected_accounts.

📄 src/util/entities/index.ts ^(MODIFY) 🔗

References

• 📄 src/util/entities/ControlledAccount.ts ^(NEW)
• 📄 src/util/entities/WhitelistBlacklistGroup.ts ^(NEW)
• 📄 src/util/entities/DiscriminatorReservation.ts ^(NEW)

Add exports for the new entities:

export * from "./ControlledAccount";
export * from "./WhitelistBlacklistGroup";
export * from "./DiscriminatorReservation";

This follows the existing pattern in the index file where all entities are exported for easy importing throughout the codebase.

📄 src/util/util/Rights.ts ^(MODIFY) 🔗

References

• 📄 src/api/util/handlers/route.ts

Add new rights flags to the Rights.FLAGS object for controlled account management as mentioned in the ticket:

• ACCOUNT_CONTROLLER: BitFlag(51) - can create and manage controlled user accounts
• CREATE_CONTROLLED_ACCOUNTS: BitFlag(52) - can create controlled user accounts
• MANAGE_CONTROLLED_ACCOUNTS: BitFlag(53) - can manage controlled accounts (delete, modify scope)
• ACT_AS_CONTROLLED: BitFlag(54) - can perform actions on behalf of controlled accounts
• RESERVE_DISCRIMINATORS: BitFlag(55) - can reserve discriminator ranges
• MANAGE_WHITELIST_GROUPS: BitFlag(56) - can create and manage whitelist/blacklist groups

These new rights integrate with the existing rights system in src/util/util/Rights.ts and follow the same BitFlag pattern used for other permissions. The rights will be checked in route handlers using the existing right: "RIGHT_NAME" pattern in the route() helper function from src/api/util/handlers/route.ts.

📄 src/util/util/Token.ts ^(MODIFY) 🔗

References

• 📄 src/api/middlewares/Authentication.ts ^(MODIFY)

Extend the JWT token system to support "acting on behalf" functionality:

1. Update the UserTokenData type to include optional acting_as field
2. Modify generateToken function to accept optional acting_as parameter
3. Update checkToken function to validate and return acting_as information
4. Add new function generateActingToken(controller_id: string, controlled_id: string) that creates tokens for controlled account actions

The token payload will include both the controller's ID (as id) and the controlled account's ID (as acting_as). This allows the authentication middleware in src/api/middlewares/Authentication.ts to properly identify both the actual user and the account they're acting as.

📄 src/api/middlewares/Authentication.ts ^(MODIFY) 🔗

References

• 📄 src/util/util/Token.ts ^(MODIFY)
• 📄 src/util/entities/ControlledAccount.ts ^(NEW)
• 📄 src/util/util/Rights.ts ^(MODIFY)

Extend the authentication middleware to support controlled accounts:

1. Add new fields to the Express Request interface:

   • acting_user_id?: string - ID of the controlled account being acted as
   • controller_id?: string - ID of the actual controlling user

2. Modify the authentication logic to handle acting tokens:

   • When a token contains acting_as, validate that the controller has ACT_AS_CONTROLLED right
   • Verify the controlled account relationship exists in the database
   • Set both req.user_id (controlled account) and req.controller_id (actual user)
   • Load rights from the controlled account, not the controller

3. Add helper function isActingAsControlled(req: Request): boolean

This extends the existing authentication flow while maintaining backward compatibility with regular user tokens. The changes integrate with the existing authentication patterns and the Rights system from src/util/util/Rights.ts.

📄 src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts ^(NEW) 🔗

References

• 📄 src/util/schemas/RegisterSchema.ts

Create a validation schema for creating whitelist/blacklist groups based on the ticket specification:

📄 src/util/migration/postgres/1756362750953-ControlledAccounts.ts ^(NEW) 🔗

Create PostgreSQL migration for the controlled accounts feature:

1. Create controlled_accounts table with proper foreign keys to users
2. Create whitelist_blacklist_groups table with owner relationship and fields for whitelist flag, guilds, users, and roles arrays
3. Create discriminator_reservations table for discriminator management with include/exclude ranges
4. Add proper indexes for performance (controller_id, controlled_id, owner_id, reservation ranges)
5. Add foreign key constraints with CASCADE delete behavior

This follows the same pattern as existing migrations and ensures database schema supports all the new entities.

📄 src/util/migration/mysql/1756362750953-ControlledAccounts.ts ^(NEW) 🔗

Create MySQL migration for the controlled accounts feature with the same schema as the PostgreSQL version but using MySQL-specific syntax and data types. This ensures compatibility across all supported database engines.

📄 src/util/migration/mariadb/1756362750953-ControlledAccounts.ts ^(NEW) 🔗

Create MariaDB migration for the controlled accounts feature with the same schema as the other database versions but using MariaDB-specific syntax where needed. This maintains consistency across all supported database engines.

I have created the following plan after thorough exploration and analysis of the codebase. Follow the below plan verbatim. Trust the files and references. Do not re-verify what's written in the plan. Explore only when absolutely necessary. First implement all the proposed file changes and then I'll review all the changes together at the end.

### Observations

The codebase is a comprehensive Discord-like server implementation called "Spacebar" with a robust user management system. It uses TypeORM entities, JWT authentication, a BitField-based rights system, and follows REST API patterns. The existing User entity has rights management, discriminator generation, and comprehensive user features. There's no existing controlled accounts system, but the foundation exists with user rights, authentication middleware, and established route patterns. The ticket requests a complex feature for parental/organizational control over user accounts.

### Approach

I'll implement the controlled accounts feature by:

1. **Database Layer**: Create new entities for controlled accounts, whitelist/blacklist groups, and discriminator reservations with proper TypeORM relations
2. **Rights System**: Add new rights flags for controlled account management following the existing BitField pattern
3. **Authentication**: Extend JWT tokens and middleware to support "acting on behalf" functionality
4. **API Routes**: Create comprehensive REST endpoints under `/admin/` for group management, controlled account CRUD, discriminator reservations, and proxy actions
5. **Validation**: Add request/response schemas following existing patterns in `src/util/schemas/`
6. **Database Migrations**: Create migrations for all supported database engines (PostgreSQL, MySQL, MariaDB)

The implementation follows the existing codebase patterns and integrates seamlessly with the current user management system.

### Reasoning

I explored the codebase structure to understand this Discord-like server implementation. I examined the User entity and rights system to understand existing user management patterns. I analyzed the authentication middleware and JWT token system to understand how to implement "acting on behalf" functionality. I reviewed existing API routes and schemas to follow established patterns. I checked the discriminator generation logic and found the route handler patterns to understand the current architecture.

## Proposed File Changes

### src/util/entities/ControlledAccount.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity to represent the relationship between controllers and controlled accounts. This entity will include:

- `id` (primary key)
- `controller_id` (foreign key to User)
- `controlled_id` (foreign key to User) 
- `created_at` timestamp
- `scope` (array of group whitelist/blacklist IDs to apply)
- `rights` (initial rights override for the controlled user)

Include proper TypeORM decorators, relations to the `User` entity from `src/util/entities/User.ts`, and validation methods. This follows the same pattern as other entities in `src/util/entities/`.

### src/util/entities/WhitelistBlacklistGroup.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity for whitelist/blacklist groups as specified in the ticket. This entity will include:

- `id` (primary key)
- `owner_id` (foreign key to User who created the group)
- `name` (descriptive name for the group)
- `whitelist` (boolean indicating if this is a whitelist or blacklist)
- `guilds` (array of guild IDs)
- `users` (array of DM target user IDs)
- `roles` (array of role IDs)
- `created_at` and `updated_at` timestamps

Include proper TypeORM decorators, relations to the `User` entity from `src/util/entities/User.ts`, and methods for resolving effective permissions. This follows the same pattern as other entities in `src/util/entities/`.

### src/util/entities/DiscriminatorReservation.ts(NEW)

References: 

- src/util/entities/User.ts(MODIFY)
- src/util/entities/BaseClass.ts

Create a new TypeORM entity to track discriminator reservations as mentioned in the ticket. This entity will include:

- `id` (primary key)
- `reserved_by` (foreign key to User who made the reservation)
- `include_start` and `include_end` (inclusive range of reserved discriminators)
- `exclude_ranges` (array of pairs representing excluded ranges)
- `created_at` timestamp
- `expires_at` (optional expiration)

Include methods for checking if a discriminator is reserved and for cleaning up expired reservations. This supports the discriminator range reserve and unreserve functionality mentioned in the ticket.

### src/util/entities/User.ts(MODIFY)

References: 

- src/util/entities/ControlledAccount.ts(NEW)
- src/util/entities/WhitelistBlacklistGroup.ts(NEW)
- src/util/entities/DiscriminatorReservation.ts(NEW)

Add new relations to the User entity to support controlled accounts:

- Add `@OneToMany` relation to `ControlledAccount` for accounts this user controls
- Add `@OneToOne` relation to `ControlledAccount` for when this user is controlled by another
- Add `@OneToMany` relation to `WhitelistBlacklistGroup` for groups owned by this user

Also add helper methods:
- `isControlledAccount()` - returns boolean if this user is controlled
- `getController()` - returns the controlling user if this is a controlled account
- `getControlledAccounts()` - returns array of accounts controlled by this user

Extend the `generateDiscriminator` method to check for reservations:
1. Before generating a discriminator, query `DiscriminatorReservation` to check if the discriminator is reserved
2. Skip reserved discriminators when generating random or incremental discriminators
3. Add helper method `isDiscriminatorReserved(username: string, discriminator: string): Promise<boolean>`
4. Add cleanup method `cleanupExpiredReservations(): Promise<void>` to remove expired reservations

These additions integrate with the existing User entity structure and follow the same patterns used for other relations like `relationships` and `connected_accounts`.

### src/util/entities/index.ts(MODIFY)

References: 

- src/util/entities/ControlledAccount.ts(NEW)
- src/util/entities/WhitelistBlacklistGroup.ts(NEW)
- src/util/entities/DiscriminatorReservation.ts(NEW)

Add exports for the new entities:

```typescript
export * from "./ControlledAccount";
export * from "./WhitelistBlacklistGroup";
export * from "./DiscriminatorReservation";

This follows the existing pattern in the index file where all entities are exported for easy importing throughout the codebase.

src/util/util/Rights.ts(MODIFY)

References:

• src/api/util/handlers/route.ts

Add new rights flags to the Rights.FLAGS object for controlled account management as mentioned in the ticket:

• ACCOUNT_CONTROLLER: BitFlag(51) - can create and manage controlled user accounts
• CREATE_CONTROLLED_ACCOUNTS: BitFlag(52) - can create controlled user accounts
• MANAGE_CONTROLLED_ACCOUNTS: BitFlag(53) - can manage controlled accounts (delete, modify scope)
• ACT_AS_CONTROLLED: BitFlag(54) - can perform actions on behalf of controlled accounts
• RESERVE_DISCRIMINATORS: BitFlag(55) - can reserve discriminator ranges
• MANAGE_WHITELIST_GROUPS: BitFlag(56) - can create and manage whitelist/blacklist groups

These new rights integrate with the existing rights system in src/util/util/Rights.ts and follow the same BitFlag pattern used for other permissions. The rights will be checked in route handlers using the existing right: "RIGHT_NAME" pattern in the route() helper function from src/api/util/handlers/route.ts.

src/util/util/Token.ts(MODIFY)

References:

• src/api/middlewares/Authentication.ts(MODIFY)

Extend the JWT token system to support "acting on behalf" functionality:

1. Update the UserTokenData type to include optional acting_as field
2. Modify generateToken function to accept optional acting_as parameter
3. Update checkToken function to validate and return acting_as information
4. Add new function generateActingToken(controller_id: string, controlled_id: string) that creates tokens for controlled account actions

The token payload will include both the controller's ID (as id) and the controlled account's ID (as acting_as). This allows the authentication middleware in src/api/middlewares/Authentication.ts to properly identify both the actual user and the account they're acting as.

src/api/middlewares/Authentication.ts(MODIFY)

References:

• src/util/util/Token.ts(MODIFY)
• src/util/entities/ControlledAccount.ts(NEW)
• src/util/util/Rights.ts(MODIFY)

Extend the authentication middleware to support controlled accounts:

1. Add new fields to the Express Request interface:

   • acting_user_id?: string - ID of the controlled account being acted as
   • controller_id?: string - ID of the actual controlling user

2. Modify the authentication logic to handle acting tokens:

   • When a token contains acting_as, validate that the controller has ACT_AS_CONTROLLED right
   • Verify the controlled account relationship exists in the database
   • Set both req.user_id (controlled account) and req.controller_id (actual user)
   • Load rights from the controlled account, not the controller

3. Add helper function isActingAsControlled(req: Request): boolean

This extends the existing authentication flow while maintaining backward compatibility with regular user tokens. The changes integrate with the existing authentication patterns and the Rights system from src/util/util/Rights.ts.

src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts(NEW)

References:

• src/util/schemas/RegisterSchema.ts

Create a validation schema for creating whitelist/blacklist groups based on the ticket specification:

export interface WhitelistBlacklistGroupCreateSchema {
  name: string; // descriptive name for the group
  whitelist: boolean; // if true, a whitelist, else a blacklist
  guilds?: string[]; // list of guild IDs
  users?: string[]; // list of DM target user IDs
  roles?: string[]; // list of role IDs
}

This follows the same pattern as other schemas in src/util/schemas/ and includes proper TypeScript interfaces with JSDoc annotations for validation.

src/util/schemas/WhitelistBlacklistGroupModifySchema.ts(NEW)

References:

• src/util/schemas/UserModifySchema.ts

Create a validation schema for modifying whitelist/blacklist groups:

export interface WhitelistBlacklistGroupModifySchema {
  name?: string;
  whitelist?: boolean;
  guilds?: string[];
  users?: string[];
  roles?: string[];
}

This allows partial updates to groups, following the same pattern as other modify schemas where all fields are optional.

src/util/schemas/ControlledAccountCreateSchema.ts(NEW)

References:

• src/util/schemas/RegisterSchema.ts

Create a validation schema for creating controlled accounts based on the ticket requirements:

export interface ControlledAccountCreateSchema {
  username: string; // name of the controlled account
  tag?: string; // discriminator (optional, will be generated if not provided)
  scope?: string[]; // array of group whitelist/blacklist IDs to apply
  rights?: string; // initial rights of the user (as string to match User entity)
}

Note that controller is implicit (the authenticated user making the request) as mentioned in the ticket. This schema follows the same pattern as existing schemas but is tailored for controlled account creation.

src/util/schemas/DiscriminatorReserveSchema.ts(NEW)

References:

• src/util/entities/DiscriminatorReservation.ts(NEW)

Create validation schemas for discriminator reservation operations based on the ticket specification:

export interface DiscriminatorRangeReserveSchema {
  include: [string, string]; // pair of discriminators denoting inclusive range
  exclude?: [string, string][]; // array of pairs denoting ranges to exclude
}

export interface DiscriminatorRangeDeleteSchema {
  reservation_id: string; // ID of the reservation to delete
}

These schemas support the discriminator range reserve and delete functionality mentioned in the ticket.

src/util/schemas/index.ts(MODIFY)

References:

• src/util/schemas/WhitelistBlacklistGroupCreateSchema.ts(NEW)
• src/util/schemas/WhitelistBlacklistGroupModifySchema.ts(NEW)
• src/util/schemas/ControlledAccountCreateSchema.ts(NEW)
• src/util/schemas/DiscriminatorReserveSchema.ts(NEW)

Add exports for all the new schemas:

export * from "./WhitelistBlacklistGroupCreateSchema";
export * from "./WhitelistBlacklistGroupModifySchema";
export * from "./ControlledAccountCreateSchema";
export * from "./DiscriminatorReserveSchema";

This follows the existing pattern in the schemas index file for easy importing throughout the codebase.

src/api/routes/admin(NEW)

I have created the following plan after thorough exploration and analysis of the codebase. Follow the below plan verbatim. Trust the files and references. Do not re-verify what's written in the plan. Explore only when absolutely necessary. First implement all the proposed file changes and then I'll review all the changes together at the end.

### Summary

# Controlled Accounts Implementation Plan

Based on my analysis of the Spacebar codebase (a Discord-like server implementation), I'll provide a comprehensive implementation plan for the controlled accounts feature as described in the GitHub ticket.

## Overview

The controlled accounts feature enables parental/organizational control over user accounts through:
- **Controlled User Management**: Create and manage accounts under supervision
- **Whitelist/Blacklist Groups**: Control access to guilds, users, and roles
- **Discriminator Reservations**: Reserve discriminator ranges for controlled accounts
- **Acting on Behalf**: Perform actions as controlled users
- **Comprehensive API**: Full CRUD operations for all components

## Architecture Analysis

The Spacebar codebase follows these patterns that we'll leverage:

### Current Structure
- **Entity System**: TypeORM entities in `src/util/entities/`
- **Rights System**: BitField-based permissions in `src/util/util/Rights.ts`
- **Authentication**: JWT tokens with middleware in `src/api/middlewares/Authentication.ts`
- **API Routes**: RESTful endpoints under `src/api/routes/`
- **Validation**: Request/response schemas in `src/util/schemas/`
- **Database**: Multi-engine support (PostgreSQL, MySQL, MariaDB)

### Key Integration Points
- **User Entity**: Existing user management with rights, discriminators, and relationships
- **Route Handler**: Standardized `route()` helper with rights checking
- **Token System**: JWT-based authentication with user validation
- **Migration System**: Database schema versioning across multiple engines

## Implementation Strategy

### 1. Database Layer (New Entities)

#### ControlledAccount Entity
```typescript
// src/util/entities/ControlledAccount.ts
@Entity({ name: "controlled_accounts" })
export class ControlledAccount extends BaseClass {
  @Column()
  controller_id: string; // Foreign key to controlling User
  
  @Column()
  controlled_id: string; // Foreign key to controlled User
  
  @Column({ type: "simple-array", nullable: true })
  scope?: string[]; // Array of whitelist/blacklist group IDs
  
  @Column({ type: "bigint", nullable: true })
  rights?: string; // Initial rights override
  
  @ManyToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "controller_id" })
  controller: User;
  
  @OneToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "controlled_id" })
  controlled: User;
}

WhitelistBlacklistGroup Entity

// src/util/entities/WhitelistBlacklistGroup.ts
@Entity({ name: "whitelist_blacklist_groups" })
export class WhitelistBlacklistGroup extends BaseClass {
  @Column()
  owner_id: string; // Foreign key to User who created the group
  
  @Column()
  name: string; // Descriptive name
  
  @Column()
  whitelist: boolean; // true = whitelist, false = blacklist
  
  @Column({ type: "simple-array", nullable: true })
  guilds?: string[]; // Guild IDs
  
  @Column({ type: "simple-array", nullable: true })
  users?: string[]; // DM target user IDs
  
  @Column({ type: "simple-array", nullable: true })
  roles?: string[]; // Role IDs
  
  @ManyToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "owner_id" })
  owner: User;
}

DiscriminatorReservation Entity

// src/util/entities/DiscriminatorReservation.ts
@Entity({ name: "discriminator_reservations" })
export class DiscriminatorReservation extends BaseClass {
  @Column()
  reserved_by: string; // Foreign key to User
  
  @Column()
  include_start: string; // Start of inclusive range
  
  @Column()
  include_end: string; // End of inclusive range
  
  @Column({ type: "simple-json", nullable: true })
  exclude_ranges?: [string, string][]; // Excluded ranges
  
  @Column({ nullable: true })
  expires_at?: Date; // Optional expiration
  
  @ManyToOne(() => User, { onDelete: "CASCADE" })
  @JoinColumn({ name: "reserved_by" })
  user: User;
}

2. Rights System Extension

Add new rights flags to src/util/util/Rights.ts:

static FLAGS = {
  // ... existing flags ...
  ACCOUNT_CONTROLLER: BitFlag(51),        // Can create and manage controlled accounts
  CREATE_CONTROLLED_ACCOUNTS: BitFlag(52), // Can create controlled accounts
  MANAGE_CONTROLLED_ACCOUNTS: BitFlag(53), // Can manage controlled accounts
  ACT_AS_CONTROLLED: BitFlag(54),         // Can perform actions on behalf
  RESERVE_DISCRIMINATORS: BitFlag(55),    // Can reserve discriminator ranges
  MANAGE_WHITELIST_GROUPS: BitFlag(56),   // Can create/manage whitelist groups
};

3. Authentication Enhancement

Token System Updates (src/util/util/Token.ts)

export type UserTokenData = {
  user: User;
  decoded: { 
    id: string; 
    iat: number; 
    email?: string;
    acting_as?: string; // ID of controlled account being acted as
  };
};

export async function generateActingToken(
  controller_id: string, 
  controlled_id: string
): Promise<string> {
  // Generate token with acting_as field for controlled account actions
}

Authentication Middleware Updates (src/api/middlewares/Authentication.ts)

declare global {
  namespace Express {
    interface Request {
      user_id: string;
      user_bot: boolean;
      token: { id: string; iat: number };
      rights: Rights;
      acting_user_id?: string;    // ID of controlled account being acted as
      controller_id?: string;     // ID of actual controlling user
    }
  }
}

4. User Entity Integration

Extend src/util/entities/User.ts:

export class User extends BaseClass {
  // ... existing fields ...
  
  @OneToMany(() => ControlledAccount, (ca) => ca.controller)
  controlled_accounts: ControlledAccount[];
  
  @OneToOne(() => ControlledAccount, (ca) => ca.controlled)
  controller_relationship: ControlledAccount;
  
  @OneToMany(() => WhitelistBlacklistGroup, (group) => group.owner)
  whitelist_groups: WhitelistBlacklistGroup[];
  
  // Helper methods
  isControlledAccount(): boolean {
    return !!this.controller_relationship;
  }
  
  async getController(): Promise<User | null> {
    if (!this.controller_relationship) return null;
    return this.controller_relationship.controller;
  }
  
  // Enhanced discriminator generation with reservation checking
  public static async generateDiscriminator(
    username: string,
    checkReservations: boolean = true
  ): Promise<string | undefined> {
    // Existing logic + reservation checking
  }
}

5. API Routes Structure

Create comprehensive admin routes under src/api/routes/admin/:

src/api/routes/admin/
├── groups/
│   ├── index.ts                    # POST /admin/groups, GET /admin/groups
│   └── #group_id/
│       └── index.ts               # GET/PATCH/DELETE /admin/groups/:id
├── controlled-accounts/
│   ├── index.ts                   # POST /admin/controlled-accounts, GET /admin/controlled-accounts
│   └── #account_id/
│       ├── index.ts              # GET/DELETE/PATCH /admin/controlled-accounts/:id
│       └── token.ts              # POST /admin/controlled-accounts/:id/token
└── discriminators/
    └── index.ts                   # POST /admin/discriminators/reserve, GET/DELETE /admin/discriminators/:id

6. Validation Schemas

Create request/response schemas in src/util/schemas/:

Group Management

// WhitelistBlacklistGroupCreateSchema.ts
export interface WhitelistBlacklistGroupCreateSchema {
  name: string;
  whitelist: boolean;
  guilds?: string[];
  users?: string[];
  roles?: string[];
}

Controlled Account Management

// ControlledAccountCreateSchema.ts
export interface ControlledAccountCreateSchema {
  username: string;
  tag?: string;           // Optional discriminator
  scope?: string[];       // Group whitelist/blacklist IDs
  rights?: string;        // Initial rights
}

Discriminator Reservations

// DiscriminatorReserveSchema.ts
export interface DiscriminatorRangeReserveSchema {
  include: [string, string];        // Inclusive range
  exclude?: [string, string][];     // Excluded ranges
}

7. Database Migrations

Create migrations for all supported database engines:

• src/util/migration/postgres/1756362750953-ControlledAccounts.ts
• src/util/migration/mysql/1756362750953-ControlledAccounts.ts
• src/util/migration/mariadb/1756362750953-ControlledAccounts.ts

Each migration will create:

• controlled_accounts table with proper foreign keys
• whitelist_blacklist_groups table with owner relationships
• discriminator_reservations table with range management
• Appropriate indexes for performance

Key API Endpoints

Group Management

• POST /admin/groups - Create whitelist/blacklist group
• GET /admin/groups - List user's groups
• GET /admin/groups/:id - Get specific group
• PATCH /admin/groups/:id - Update group
• DELETE /admin/groups/:id - Delete group

Controlled Account Management

• POST /admin/controlled-accounts - Create controlled account
• GET /admin/controlled-accounts - List controlled accounts
• GET /admin/controlled-accounts/:id - Get controlled account details
• DELETE /admin/controlled-accounts/:id - Delete controlled account
• PATCH /admin/controlled-accounts/:id/scope - Apply group restrictions
• POST /admin/controlled-accounts/:id/token - Generate acting token

Discriminator Management

• POST /admin/discriminators/reserve - Reserve discriminator range
• GET /admin/discriminators/:id - Fetch reservation details
• DELETE /admin/discriminators/:id - Delete reservation

User Deletion (Enhanced)

• POST /users/:id/delete - Regular deletion with retention policies
• DELETE /users/:id - Right-to-erasure deletion

Security Considerations

Rights-Based Access Control

• All operations require appropriate rights flags
• Controllers can only manage their own controlled accounts
• Discriminator reservations are user-specific
• Acting tokens include both controller and controlled user context

Validation and Error Handling

• Comprehensive input validation using existing schema system
• Proper error codes (400, 403, 404) as specified in ticket
• Cascade deletion for data consistency
• Token validation for acting-on-behalf functionality

Integration Benefits

Seamless Integration

• Leverages existing User entity and rights system
• Uses established route handler patterns with rights checking
• Follows existing authentication and token patterns
• Maintains database compatibility across all supported engines

Extensibility

• Modular design allows for future enhancements
• Rights system can be extended for additional permissions
• Group system supports complex whitelist/blacklist combinations
• Discriminator reservation system supports flexible range management

This implementation provides a comprehensive controlled accounts system that integrates seamlessly with the existing Spacebar architecture while meeting all requirements specified in the GitHub ticket.
