Engineering notes for HomeBlocks — a crash-consistent block-volume store built on HomeStore.

• Folly to Coroutine Migration — for engineers who know the old Folly-future architecture: how the I/O path works on the new C++23 sisl::async coroutine ("v8") stack, focused on the two things that actually changed how you write code — the heap/allocation model and the threading/affinity model.

• Coroutines as State Machines — the mental model underneath the migration: what the compiler lowers a co_await function into (frame + state-machine resume()), and how that differs from a stackful folly::fibers task. Read it if the frame/continuation/thread-hop mechanics feel like magic.

(Start here if you're picking up HomeBlocks/HomeStore after the v8 coroutine migration.)
