## Overview
The `ILabRegistry` interface defines a comprehensive system for managing and tracking research laboratory entities on the ChunkNet blockchain. It provides mechanisms for registering, updating, and managing lab metadata, researchers, and lifecycle states.

## Interface

| Function | Visibility | Description | Parameters | Returns |
|----------|------------|-------------|------------|---------|
| `registerLab` | External | Register a new lab | `name`, `description`, `metadataHash` | `labId` |
| `updateLabDetails` | External | Update existing lab metadata | `labId`, `newName`, `newDescription`, `newMetadataHash` | - |
| `addResearcher` | External | Add authorized researcher | `labId`, `researcherAddress` | - |
| `removeResearcher` | External | Remove authorized researcher | `labId`, `researcherAddress` | - |
| `getLab` | External View | Retrieve lab details | `labId` | `LabEntity` |
| `isAuthorizedResearcher` | External View | Check researcher authorization | `labId`, `researcherAddress` | `bool` |
| `deactivateLab` | External | Disable lab modifications | `labId` | - |

## Events
- `LabRegistered`: Triggered when a new lab is registered
- `LabUpdated`: Emitted when lab details are modified

## Storage Layout
- `LabEntity` struct contains:
  - `owner`: Lab owner's address
  - `name`: Lab name
  - `description`: Lab description
  - `metadataHash`: Content/IPFS hash
  - `registrationTimestamp`: Creation timestamp
  - `isActive`: Current lab status
  - `authorizedResearchers`: List of permitted researchers

## Access Control
- Lab registration requires unique naming
- Only lab owners can modify lab details
- Researcher addition/removal restricted to lab owner
- Deactivation prevents further modifications

## Security Considerations
- Use input validation for lab names and descriptions
- Implement access control checks in implementation
- Consider rate limiting for registration
- Validate researcher addresses
- Use cryptographic hashing for metadata integrity

## Deployment
- **RPC URL**: https://rpc.chunknet.org
- **Chain ID**: 214562
- **Recommended Deployment Steps**:
  1. Compile with Solidity 0.8.19
  2. Use ChunkNet deployment scripts
  3. Set initial owner/admin
  4. Verify contract on explorer

## Testing
- Unit test lab registration workflow
- Test researcher authorization mechanisms
- Validate metadata update restrictions
- Check deactivation behavior
- Perform boundary testing on input parameters
- Simulate edge cases in researcher management
