The ikigai Book
gonk is built from the pieces The ikigai Book teaches: resources named by URIs and resolved by a kernel, spaces composed into a host, capabilities that are declared and enforced, golden threads that say what a write invalidates, and the transports that make a kernel reachable from another process or another machine. This book uses those ideas without re-teaching them; that book is where they are taught, from the first endpoint up.
The two books are built, tested and published together, from one repository: https://github.com/ikigai-rs/ikigai-tutorial.
