Deprecated: Parse is provided for backward compatibility only. Use ParseFromModelTokens with a []models.TokenWithSpan slice from the tokenizer instead. This shim wraps each token.Token into a zero-span models.TokenWithSpan and has no position information. Parse parses a slice of token.Token into an

(tokens []token.Token)

// Thread Safety: NOT thread-safe - use separate parser instances per goroutine.

	wrapped := make([]models.TokenWithSpan, len(tokens))
	for i, t := range tokens {

// parseTokens is the core parsing routine. It takes a preprocessed
