Description

Made validation optional
Introduced STRICT_VALIDATION environment variable to control whether failures stop execution or just log errors.

Changed return type from None to bool
Instead of raising exceptions, the function returns False on failure, allowing other models to continue.

Replaced hard failures with logging
Errors are now logged instead of stopping execution unless strict validation is enabled.

Ensures all models continue logging even if one fails
By returning False, the function allows other models to log their forecasts without interruption.

Fixes #248
