## Overview
`LabContract` is a sophisticated smart contract designed to manage scientific experiments on the blockchain. It provides a robust framework for creating, tracking, and managing experimental configurations with integrated funding and status tracking mechanisms.

## Interface
| Function | Parameters | Returns | Description |
|----------|------------|---------|-------------|
| `createExperiment` | `fundingAmount`, `configHash` | `bytes32` | Create a new experiment with initial funding |
| `updateExperimentStatus` | `experimentId`, `newStatus` | `void` | Toggle experiment active status |
| `getExperimentDetails` | `experimentId` | `ExperimentConfig` | Retrieve full experiment configuration |
| `withdrawFunds` | `experimentId`, `amount` | `void` | Withdraw funds from an active experiment |

## Events
- `ExperimentCreated`: Emitted when a new experiment is initialized
  - `experimentId`: Unique identifier
  - `creator`: Experiment creator's address
  - `fundingAmount`: Initial funding amount

- `ExperimentUpdated`: Emitted when experiment status changes
  - `experimentId`: Unique identifier
  - `isActive`: New active status

## Storage Layout
- `experiments`: Mapping of experiment IDs to `ExperimentConfig`
- `creatorExperiments`: Mapping tracking experiments per creator
- `ExperimentConfig` struct contains:
  - `creator`: Experiment initiator
  - `startTimestamp`: Experiment creation time
  - `fundingAmount`: Available experiment funds
  - `isActive`: Current experiment status
  - `configHash`: Experiment configuration identifier

## Access Control
- Uses OpenZeppelin's `Ownable` for contract-level administration
- Experiment creators have exclusive rights to:
  - Update experiment status
  - Withdraw experiment funds

## Security Considerations
- `nonReentrant` modifier prevents recursive calls
- Strict access controls on critical functions
- Validates input parameters
- Checks experiment creator before allowing modifications
- Requires positive funding amounts
- Validates experiment existence before operations

## Deployment
### ChunkNet Deployment Parameters
- **RPC URL**: https://rpc.chunknet.org
- **Chain ID**: 214562
- **Required Constructor Parameters**:
  1. `_registryAddress`: LabRegistry contract address
  2. `_helperAddress`: LabHelper contract address

### Deployment Script Example
bash
forge create LabContract \
  --rpc-url https://rpc.chunknet.org \
  --constructor-args $LAB_REGISTRY_ADDRESS $LAB_HELPER_ADDRESS


## Testing
### Recommended Test Scenarios
- Experiment creation with valid parameters
- Status update permissions
- Fund withdrawal mechanics
- Edge case handling:
  - Zero funding amount
  - Invalid experiment ID
  - Unauthorized status modifications
- Verify event emissions
- Validate access control mechanisms

### Test Coverage
- Unit tests for each function
- Integration tests with registry interactions
- Fuzz testing for input validation
- Simulation of various experiment lifecycle stages
