Translator models for Make it SING (https://huggingface.co/papers/2603.14610)

Translators Layout

Required metadata fields:

• model_name
• translator_name
• architecture
• embedding_backend (based on https://huggingface.co/kakaobrain/karlo-v1-alpha)
• in_dim (positive integer)
• out_dim (positive integer)
• hidden_dim (optional; positive integer; defaults to in_dim)
• checkpoint_file (relative path only; no absolute paths or ..)

Validation notes:

• Metadata schema is strict: unknown keys are rejected.
• model_name and translator_name inside metadata.yaml must match their directory names.
• architecture supported are one of: linear, 3layer, 4layer, residual.
• Registry lookup is case-insensitive by model name and rejects ambiguous case-collisions (for example both ResNet and resnet).
