Shared utilities for embedding input sanitization and response handling.

Functions

compute_norm

Compute L2 norm of a vector

handle_embedding_response

Replace embeddings for originally-invalid inputs with zero vectors.

is_embeddable

Returns true if s is non-empty after stripping ASCII whitespace.

l2_normalize

L2 normalize a vector to unit length

mean_pool

Mean pooling over sequence dimension with attention mask

sanitize_embedding_inputs

Replace empty/whitespace-only strings with "." to prevent API errors.
