I would like to know information on Sri keyuravati of Kashmir shaivism who was a central figure in krama lineage.

Would like to know about life. Important events and books written if any.

Also about guru and sishyas

We find a reference of her as the Guru of Govindaraja and as the disciple of a Sri Vidya Parampara Guru called Shiva Ananda Natha.

One special type of Shakta Yoga, which is related to the Shambhopaya technique of the Trika system, is called "Kalinaya".

Keyuravati was adept in this form and was an important female Guru in this lineage too.

There is a special type of shAkta yoga known as kAlInaya. It was
originated by one shivAnandanAtha about whom we know very little. He
imparted it to three female disciples named keyUravatI, kalyANikA and
madanikA. We know that govindarAja learnt it from keyUravatI and then
imparted it to the great philosopher somAnanda. kAlInaya reached
abhinavagupta through the line of ujjaTa, udbhaTa etc. erakanAtha, the
disciple of kalyANikA, engaged himself in attaining supernatural
powers and did not initiate any disciple in the path. This information
about the origin and spread of kAlInaya has been provided by jayaratha
in his commentary on tantrAloka. He bases the information on the
kramakeli of abhinavagupta and quotes a long passage from it. Passages
in kAshmIra-apabhramsha, quoted by abhinavagupta in his tantrasAra and
parAtrimshikAvivaraNa, may have been drawn from the sayings of works
of the above mentioned three female preceptors. These three highly
respected yoginis may have preferred to teach in the language of the
common people, as did lalleshvarI in the fourteenth century A.D.
shivAnanda, being the great-grand teacher of somAnanda, may have
flourished sometime in the eighth century A.D.
