## ADDED Requirements

### Requirement: GitLab storage options SHALL validate configuration parameters

GitLabStorageOptions SHALL validate all configuration parameters to prevent runtime errors and provide clear error messages.

#### Scenario: Timeout validation in storage options
- **WHEN** GitLabStorageOptions is created with timeout parameter
- **THEN** options SHALL validate timeout is positive number
- **AND** SHALL enforce maximum timeout (3600 seconds)
- **AND** SHALL raise ValueError with descriptive message for invalid values
- **AND** SHALL document valid range in error message

#### Scenario: Maximum pages validation in storage options
- **WHEN** GitLabStorageOptions is created with max_pages parameter
- **THEN** options SHALL validate max_pages is positive integer
- **AND** SHALL enforce reasonable maximum (10000 pages)
- **AND** SHALL raise ValueError with descriptive message for invalid values
- **AND** SHALL document valid range in error message

#### Scenario: Environment variable validation
- **WHEN** GitLabStorageOptions loads configuration from environment variables
- **THEN** options SHALL validate timeout and max_pages from environment
- **AND** SHALL use sensible defaults for missing or invalid values
- **AND** SHALL log warnings when using fallback values

#### Scenario: Configuration validation error messages
- **WHEN** GitLabStorageOptions detects invalid configuration
- **THEN** error message SHALL clearly indicate which parameter is invalid
- **AND** SHALL provide guidance on valid range or format
- **AND** SHALL include current value for debugging
- **AND** SHALL suggest corrective action when possible

### Requirement: Storage options SHALL provide resource cleanup guidance

Storage options classes SHALL provide clear guidance on resource cleanup for filesystems that require explicit cleanup.

#### Scenario: Resource cleanup documentation
- **WHEN** GitLabStorageOptions creates GitLabFileSystem instance
- **THEN** options SHALL document need for explicit cleanup
- **AND** SHALL provide example of proper cleanup pattern
- **AND** SHALL recommend context manager usage when appropriate

#### Scenario: Cleanup method availability
- **WHEN** GitLabStorageOptions creates filesystem instance
- **THEN** resulting filesystem SHALL provide close() method
- **AND** storage options SHALL document cleanup requirements
- **AND** SHALL indicate when cleanup is optional vs required
