Nice work! Congrats on your publication.

For future reference, you might be interested in comparing your work to "Light-weight Bounds Checking" (CGO 2012; https://www.seclab.cs.sunysb.edu/seclab/pubs/lbc.pdf), which pioneered the general two-stage "check if the value is possibly a red zone value, if so do a slow-path check" approach.
