## ADDED Requirements

### Requirement: Centralized logging configuration module

The system SHALL provide a centralized logging configuration module
`fsspeckit.common.logging_config` that configures package-wide logging and
provides module-level loggers.

#### Scenario: Setup logging configures handlers and levels
- **WHEN** a caller invokes `setup_logging()` with optional overrides for
  level and format
- **THEN** log records emitted from `fsspeckit` modules SHALL use that
  configuration (handlers, level, and format)
- **AND** the defaults SHALL provide console logging with a timestamp, module
  name, level, and message.

#### Scenario: Module-level loggers use get_logger
- **WHEN** a module in `fsspeckit` obtains a logger via
  `get_logger(__name__)`
- **THEN** the returned logger SHALL be attached to the centralized logging
  configuration
- **AND** log messages from that module SHALL respect the configured level,
  format, and handlers.

### Requirement: Standardized logger usage patterns

Core and dataset modules SHALL use consistent logger usage patterns for
structured, context-rich messages and exception reporting.

#### Scenario: Log levels follow documented guidelines
- **WHEN** modules emit log messages for normal operations, recoverable
  issues, or errors
- **THEN** they SHALL use `DEBUG` for diagnostic detail, `INFO` for
  high-level operations, `WARNING` for recoverable issues, and `ERROR` or
  `CRITICAL` for serious failures
- **AND** messages SHALL include relevant context such as operation name and
  resource identifiers.

#### Scenario: Exceptions are logged with stack traces
- **WHEN** a module logs an exception inside an error-handling block
- **THEN** it SHALL use logger calls with `exc_info=True` (or equivalent)
  so that stack traces are captured in logs
- **AND** unexpected exceptions SHALL be logged before being propagated.
