+## Origins and papers
+CN was first described in [CN: Verifying Systems C Code with Separation-Logic Refinement Types](https://dl.acm.org/doi/10.1145/3571194) by Christopher Pulte, Dhruv C. Makwana, Thomas Sewell, Kayvan Memarian, Peter Sewell, and Neel Krishnaswami, in POPL 2023.
+The Fulminate system for runtime testing of CN specifications was first described in [Fulminate: Testing CN Separation-Logic Specifications in C](http://www.cl.cam.ac.uk/users/pes20/cn-testing-popl2025.pdf), by Rini Banerjee, Kayvan Memarian, Dhruv Makwana, Christopher Pulte, Neel Krishnaswami, and Peter Sewell, in POPL 2025. 
 To accurately handle the complex semantics of C, CN builds on the [Cerberus semantics for C](https://github.com/rems-project/cerberus/).
 Some of the examples in this tutorial are adapted from Arthur Charguéraud’s excellent
 [Separation Logic Foundations](https://softwarefoundations.cis.upenn.edu) textbook, and one of the case studies is based on an
