This repository contains the artifacts of my master thesis "A logic for reasoning with mailbox types in separation logic".

The Rocq development is known to compile with:

• Rocq version 9.1.0
• OCaml version 4.14.1
• rocq-iris version dev.2025-11-19.0.ddfb616b
• rocq-iris-heap-lang version dev.2025-11-19.0.ddfb616b
• rocq-stdpp version dev.2025-11-18.2.f049a0f8

Ensure that opam is installed on your system and install the dependencies:

opam switch create iris-zanaris ocaml-base-compiler.4.14.1
eval $(opam env)
opam switch link iris-zanaris .
opam repo add iris-dev https://gitlab.mpi-sws.org/iris/opam.git
opam pin add --kind version rocq-iris-heap-lang "dev.2025-11-19.0.ddfb616b"

To build the project, run make -jN, where N is the number of CPU cores to use.
